    DETAILED DESCRIPTION It is well known that in a tile cutting machine, the engraving tool is attached to a lower end of a tool holder 1. Typically, the tool has the shape of a wheel R, which is made of hard metal, and is attached in a lower region of a tool holder body 1 a, from which an actuating handle 1 b extends.
    2.13
    AT15 701 U1 2018-04-15 Austrian
    Patent Office The tool holder body 1a is traversed in the longitudinal direction by a continuous slot 2, which forms a sliding seat of a guide rod, not shown, of the tile cutting machine. Since the guide rod typically has a rectangular cross section, the slot 2 also has on the inside at least two planar sliding or sliding surfaces 2 ′ arranged parallel to one another, as shown in FIG. 2. The tool holder 1 is normally made of a light metal alloy, for example aluminum, by casting and then straightening the workpiece surfaces: the shape and size of the slot and the corresponding sliding surfaces 2 'is therefore fixed.
    According to the invention, one of the two lateral surfaces 2 'of the slot has a cutout 3 which forms an access to an adjacent housing space 4. The housing space 4 acts as a seat for a support roller 5 which is rotatably held on a pivot 6, for example via two bearings 5 '. The roller 5 is preferably made of a more ductile material than that of the guide rod so that it does not damage the surface of the guide rod; for example, the roller 5 is made of a self-lubricating plastic material, such as Teflon.
    The pivot 6 is in turn received with its ends in holding openings which are arranged in end blocks of a cradle or storage 7.
    The storage 7 partially takes up the cylindrical circumference of the roller 6 and thus represents a covering half-box, which completes the protection of the roller 6 as soon as it is inserted into the seat 4 of the tool holder.
    In addition, the bearing 7 has two through openings 7a and 7b, which is formed in the end blocks perpendicular to the axis of the pivot 6. In the through openings 7a and 7b, fastening and adjusting screws 8a and 8b are to be used, which interact with corresponding, threaded openings 9, which are correspondingly formed on the tool holder body, as shown in FIG. 3. The openings are preferably arranged at the two opposite corners of the bearing 7, which has a substantially rectangular shape in plan view; in any case, the openings 7a and 7b are not aligned on the same side of the bearing 7, so that the fastening force is better distributed on the bearing body and consequently on the roller without generating torques which would lead to the bearing being related to twist on the base of the tool holder 1a, which would have the consequence that the storage would have an undesirable play.
    Between the bearing 7 and the main body of the tool holder 1a are preferably elastic means, which are not shown and are provided to push the bearing away from the tool holder, counter to the force of the fastening and adjusting screws 8a and 8b. The elastic means have, for example, the shape of a spring washer or disc spring which is wedged onto the shaft of the fastening and adjusting screws 8a and 8b.
    Once the roller 5 is assembled with the bearing 7 and this assembly is mounted in the housing space 4 of the tool holder body (Fig. 1), the roller 5 is placed so that it protrudes slightly from the cutout 3 and on the guide rod, if this is inserted through the slot 2, rests, which leads to the establishment of a positioning guideline for the tool holder 1. As a result, two opposing support or positioning guidelines of the guide rod are defined within the one slot and thus restrict lateral movements: on one side an inner surface 2 'of the tool holder and on the other side the generatrix of the roller 5. During the movement of the Tool holder on the guide rod thus creates a lateral guide that is slidable on one side and rolling on the other side.
    In order to achieve the best possible support of the roller 5 on the guide rod during the displacement of the tool holder on the guide rod in the different pivot positions that the tool holder can assume, the axis of the pivot pin 6
    3.13
    AT15 701 U1 2018-04-15 Austrian
    Patent Office arranged at an angle no greater than 30 ° with respect to the supporting axis, i.e. the axis that passes through the wheel R and is perpendicular to the tile during the engraving step. This position is such that the axis of rotation of the pin 6 remains mainly perpendicular to the direction of progress of the tool holder during engraving and therefore the roller interacts with the guide rod in an almost ideally rotating manner.
    Since the wear due to the shifting over time reduces the diameter of the roller 5, which certainly wears out earlier than the guide rod and the sliding surfaces 2 'within the slot, it is possible to act on the fastening and adjusting screws 8a and 8b, to move the cradle or storage slightly closer to the tool holder body 1a by overcoming the restoring force of the elastic means, for example the Belleville washers. In this way, even a slight play can be absorbed in a controlled manner, which may have occurred within the slot due to the reduction in the diameter of the roller 5.
    In view of the guiding accuracy that can be achieved with any wear condition of the tool holder, it is preferred that the tool is also adequately constructed in order to achieve a degree of precision of the same order of magnitude.
    For this purpose, according to a preferred embodiment, the tool holder is provided with a lubrication system, for example as described in Applicant's Italian Utility Model No. 270 567.
    In particular, and preferably on the same side on which the cradle or storage of the adjustment device is installed, a recessed and elongated seat is held for receiving a compressible tank 10 which serves as a tank for lubricating oil.
    The tank 10 is obtained by being molded from a thin plastic film and has a flat wall on which a thinly shaped wall is instead arranged to form a kind of semi-cylindrical bottle. At one end of the cylindrical bottle there is a short delivery channel with a bottle neck 10a which prevents oil flow from the cylindrical bottle in the absence of excess pressure. At the other end of the discharge channel, a conical chamber 10b with an outlet 10c is formed, at the apex of which an oil discharge hole is made. The tank 10, as shown in the drawings, is held in its seat in the tool holder by a simple connection, ensuring that the chamber with the outlet is arranged in the lower region, the discharge opening being inserted into a delivery channel 11 is. The channel 11 is preserved in the thickness of the body of the tool holder 1a and connects the lower region of the tank seat with the seat of the actual tool, i.e. the wheel made of hard metal R, as shown in FIG. 6.
    In a preferred arrangement it is thus provided that the seat of the tank 10 is elongated as such and has a longitudinal axis which radially extends from the axis of rotation of the edge R and is oriented in the direction of the base body of the tool holder.
    The delivery channel 11, which opens to the outside of the tool holder, in the absence of the tank 10, can also be used to insert the discharge end of an oil supply device. If, instead, the tank is present and filled with oil, the lubrication of the gravity wheel R can be carried out easily by pressing lightly on the flexible bottle, so that the pressure therein is temporarily increased and the oil causes the bottle neck in the delivery channel overcome until it flows out of the dispensing opening.
    It has proven to be advantageous to improve this arrangement by providing a delivery rod 12. Depending on the ambient conditions, the arrangement of the bottle neck 10a and the conical chamber 10a may not be sufficient to prevent an unimpeded discharge of oil from the outlet 10c, which can lead to premature consumption of the lubricating oil from the cylindrical chamber 10. The rod 12 has a shape with a thin semi-rigid core, having a diameter slightly smaller than the diameter of the outlet opening 10c, and having a porö4 / 13
    AT15 701 U1 2018-04-15 Austrian
    Patentamt sen surface is provided, which is able to withdraw oil from the conical chamber 10b and this by capillary action to the other end. The rod 12 preferably consists of a metallic, twisted wire core, which is provided with soft bristles, similar to the known brush tube cleaner.
    The rod 12 is received in the channel 11, one end being in contact with the cutting wheel R and the other end inserted into the conical chamber 10b and partially closing the outlet opening 10c.
    The arrangement of the rod 12 has proven to be excellent in order to deliver the correct amount of oil to the cutting wheel R by capillary action, whereby an overflow of the oil from the tank 10 is prevented.
    7A to 7C show steps of assembling the tank 10 to the tool holder: first, the rod 12 is inserted into the outlet opening 10c in a direction aligned with the central axis of the channel 11; then the tank 10 is rotated to insert it into its seat, bending the rod 12 a few degrees.
    Based on the above description, it should be clearly understood that the device according to the invention enables a perfect solution to the tasks set out in the introduction. In particular, the tool holder according to the present invention can be easily adjusted, and therefore its sliding accuracy on the guide rod can be maintained over time. The engraving accuracy is also obtained consistently and synergistically through proper lubrication of the engraving wheel by embedding a suitable lubrication device in the tool holder.
    It is pointed out, however, that the protection of the presently described invention is not limited to the specifically illustrated embodiment, but extends to any other design variants that achieve the same benefit.
    In particular, although a preferred version of the device is shown, the option is not excluded that a support cradle or support bearing of the support roller is provided on both sides of the tool holder. The duplication of the adjustment device is not absolutely necessary in view of the costs and the complications that this entails, although it enables further advantages in terms of adjustment accuracy and symmetry to be achieved.
