    A bearing arrangement for a feeding device for a drilling machine, comprising a feeding beam (1) provided with longitudinal guides (6), a carriage supporting a drilling machine (3) and provided with guide surfaces in slidable engagement with the guides, and displacing means for displacement of the carriage along the guides. At least one guide surfce (5a) of the carriage is formed by a spacer (5) supported by the carriage. For automatical eliminatin of the clearance between the feeding beam and the carriage, the spacer is pressed against a wedging surface (8) provided on the carriage and extending essentially in parallel with the guide. The carriage is provided by means (9) for displacement of the spacer in between the guide surface (6a) of the guide of the feeding beam and the wedging surface (8) of the carriage so that the growth of clearance caused by wearing of the spacer is avoided as the wearing increases.

    The invention relates to metal cutting.
    The purpose of the invention is to improve accuracy by providing self-regulation of the carriage on guide rails.
    FIG. 1 shows the feeding device of the drilling machine, side view; Fig. 2 shows the construction of the bearing surface of the guide, longitudinal section (version I) in Fig. 3 - the same; view from above; in fig. 4 - diagram of the operation of the bearing surface design, partial section (version II); in fig. 5 shows the construction of the bearing surface as shown in FIG. 4, longitudinal section; in fig. 6 - the same, top view; in fig. 7 - bearing surface design, longitudinal section (version III).
    The feeding device includes an elongated feeding beam 1 and a carriage 2h which can move along it. Drilling ctaHOK 3 is located on beam 1. The carriage moves along the longitudinal guides on the feeding beam, using a feeding chain, first in the direction of drilling A to drill a hole in the rock, and then in the opposite direction B to remove spindles from the drilled hole and return the drilling machine to Initial position, at the end of the supply beam. Between the carriage and the feed beam (in Figs. 2 and 3), two gaskets 4 and 5 are installed, which form guide surfaces 6-9, with which the gaskets are pressed against the guides 10 of the delivery beam 1. The gasket 5 has the shape of a wedge and forms The sliding surface 11, which is pressed against the wedging surface 12 on the carriage. The angle between the guide surface 8 of the gasket and the sliding surface 11 is equal to the angle between the wedging surface of the carriage and the corresponding surface 13 of the feed beam. The wedging surface of the carriage approaches the guide in the direction of drilling A. Between the carriage and the gasket there is a means of displacement in the form of a spring 14, which presses the gasket in the direction of drilling to the carriage.

    the springs are chosen so as to prevent the gasket from sticking when the carriage begins to move in the opposite direction B.
    The design of the bearing surface of the guide for the feeder of the boring machine (version I) works as follows.
    The spring pushes the gasket into a wedge-shaped gap between the feed beam guide and the wedging surface of the carriage with a force determined by the spring stiffness, whereby the gasket eliminates the gap between the feed beam and the carriage. When the guide surfaces wear out, the gasket automatically pushes deeper into the space between the beam and the carriage, which ensures precise carriage adjustment. When the carriage is withdrawn in the opposite direction, a gasket in a similar way allows the carriage to slide along the feed beam without a gap. Since the proppant carriage surface is located under the inclination to the other guide surfaces 6, 7, and 9 of the carriage (Fig. 2), the gasket eliminates the gap in the direction of height and in the direction of the width of the carriage.
    The carriage has an adjusting means in the form of a screw 15 (Fig. 3), with which it is possible to limit the penetration of the gasket into the wedge-shaped gap between the carriage and the feeding beam, which provides the required clearance between the carriage and the beam. The adjustment screw can also be installed from the opposite gasket to limit the movement of the gasket in both directions.
    The displacement means in the form of a feeding chain 16 (as shown in FIGS. 4-6) is intended to move the carriage along the guide beam. For this, the chain 16 has a stop 17 provided with a lever 18, which, in turn, engages with a slip for the finger 19 protruding from the gasket 20. The latter is connected to the chain 16. The carriage has two bearing surfaces 21 and 22, between which there is the chain stop 17 of the chain 16. The distance between the support surfaces 21 and 22 is such that when the chain 16 moves in the opposite direction, the lever 18 moves and contacts the finger head 23 before the stop G7 touches the support:
    When the chain 16 moves in the direction of drilling, the stop 17 contacts the other support surface 22, preventing contact by the lever 18 of the gasket 20. The spring 14 on the carriage pushes the gasket 5 in the direction of drilling. The finger 19 of the gasket and the supporting surfaces 21 and 22 of the carriage ki are arranged relative to each other so that the lever 18 leads the gasket 20 out of the gap between the carriage and the feeding beam, but only so as to prevent unintentional sticking during the return movement and to maintain effective setting the direction of the carriage 2 along the feeding beam 1.
    The gasket 20 has sliding surfaces 24 and 25 corresponding to two wedge surfaces 26 and 27, which form the propping surface of the carriage 2 (Figs. 5 and 6). The wedge surfaces 26 and 27 are located one behind the other in the direction of motion and. Such a constructive extension increases the area of the wedging surface.
    The sliding surface 28 of the gasket 29, as well as the proppant surface 30 of the carriage 2 (Fig. 7) is formed by cylindrical surfaces having equal radii and coaxial. The axes of the cylindrical surfaces are inclined relative to the guide surface 8 of the gasket, with the result that the gasket can rotate relative to the longitudinal axis on the wedging surface. Regardless of wear, the guide surface 8 of the gasket is always parallel to the surface of the guide 10 of the feed beam 1.
