The device is equipped with a system for centering the replacement part, first on one centering element, and then on two. 5 hp f-ly, 5 ill. The invention relates to mechanical engineering and can be used to orient parts relative to each other. The purpose of the invention is to improve the accuracy of attachment of a replacement part due to the fact that the high-precision orientation of both base axes relative to each other can not only be adjusted, but also be maintained under different operating conditions. Fig, 1 shows a device, axonometric; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section bb of fig 2; in fig. (—the scheme of interaction of the centering element with the supporting and guiding element and the landing / lny element; FIG. 5 is the layout of the device. The device has a frame i, along which the rack 2 horizontally moves. On the front side of the rack 2, the carrier part 3 is placed, is moved; on the vertical guide bars k. On the front side of part 3, a replaceable part 5 is fixed, in this example a spindle head. The D / gtal 5 has on its back side T-shaped vertical guide grooves 6, in which the clamping elements of the carrier part 3 enter. On the front side of the part 5 there is a spindle 7. In the rack 2 there is a spindle drive unit 7. The shaft 8 of this device runs vertically inside the rack 2 and is connected to a horizontal shaft that passes inside the part 3. A spindle 7 is connected to it. The drive shaft of the spindle passes in part 3 along the reference axis 9 of this part (FIG. 3). The reference axis 10 of the replacement part 3 is the spindle axis. The carrier part 3 has four clamping elements 11, respectively, consisting of a rod 12 which is horizontally displaced in the carrier part 3 and a wider head 13 provided at the outer end of the rod. The outer end of the rod 12 and the head 13 are inserted into T-shaped grooves. Clamping tool element 11 consists of a wedge transmission 1 (in which the inclined pusher 15 is included in the inclined transverse groove 16 of the rod 12. The pusher 15 about mounted on a piston 17 located in a cylinder 18, in which a spring 19 is installed, cooperating on a piston 17 in the direction of the rod 12, whereby the rod is pressed from the part 5. To release element 11, pressure 20 is supplied through pipe 20 -7 is pressed. As a result, the element 11 for releasing the part 5 exits the part 3. By means of the spring 19, the clamp is maintained when the pressure is released. The four clamping elements 11 are arranged in a rectangular pattern, controlled synchronously. The rod 12 of each clamping element 11 passes through the hole a block 21 fixed on the front surface of the part 3- Each block 21 has on its front side two protruding finely machined guide surfaces 22 to which the part 5 is pressed by clamping elements 11. All surfaces 22 are located in a common vertical plane 23. In the supporting plane 23, the rear wall of the part 5 is in contact with eight surfaces 22. On the rear wall of the part 5 there are three centering elements 2C-26. Each element has an inclined surface 27, a flat surface 28 located at a right angle to the plane 23. The surface 28 is parallel to the surface 29 of the elements 30 and 31 fixed to the front wall of the bearing part. An element 30 in the form of a crosspiece with surfaces 29 is provided for both centering elements 2k and 25. These surfaces extend at a height of the horizontal axis 32 of the coordinate system 33, whose center is located on the base axis 9. On the vertical axis 3, a vertical guide surface 29 is arranged. Each surface 29 interacts with the clamping element 35, which is arranged to move in part 3 parallel to the axis 9. The front end of the element protrudes from part 3. Element 35 is made with an inclined surface B3 parallel to the surface 27 of the centering element. When the part 5 is placed on the part 3, the head of the centering element enters the gap between the guide surface 29 and the surface 36. When the element 35 is extended from the part 3, the elements 2k-26 are pressed to the surface 29. The gaps between the elements 35 and 30 are arranged vertically, so that the centering elements with their horizontal bearing surface are pressed down to the surfaces 29. The element 2b is pressed with its supporting surface against the vertical surface 29 of the element 31. Thus, the axes 9 and 10 are oriented with one the other, with three centering elements located at a distance from the spindle 7. The element 35 is connected to a piston 37, which moves in a cylinder 38 housed in the part 3. The piston moves due to the pressure in the pipe ten 15 20 25 water 39 and is pressed by the spring 0 Due to the pressure in the pipe 41, the piston when the spring is compressed (0 rystnl- with back. The spring 40 prevents the part 5 from moving when the pressure disappears. The device works as follows. To center and clamp the workpiece 5 on the workpiece 3, the workpiece 5 is moved vertically behind the heads 13. Then, the side centering is performed by extending the lower clamping element cooperating with the item 26. Then the vertical centering is performed by actuating both elements 35 interacting with the centering elements and 25. The axis 9 and 10 are brought into coincidence, and at the same time four clamping elements 11 are drawn into the part 3, the replacement part 5 is clamped onto the part 3. In case of unintentional unclamping, the part 5 is held by the T-shaped grooves and rests on the guiding surfaces of the elements 24 and 25. With a possible change in the length of the part 5, the coincidence of the axes 9 and 10 is maintained. The position of the pistons 17 and 37 can be controlled by using hydraulic or pneumatic control channels, the flow through which can occur only at certain piston positions. Thus, it can be monitored whether the clamping elements 11, the pistons 37 are in the working position. Nozzle orifices may be provided on the support surfaces 22 and 29, from which compressed air flows out in order to clean the support surfaces and determine through the sensing elements whether part 5 is in the resting position, a, in which it closes the nozzle openings. On the heads 13, rollers can be placed in order to reduce the loss of friction when entering and releasing the part 5 and to avoid wear on the bearing surfaces 22. FIG. 5 shows the arrangement of the three guide surfaces 29 on the front side of the part 3. The centering elements are fastened not to the part, but to the replacement part. The arrows indicate the direction of action of the clamping elements here. thirty 35 40 45 50 7152 800 While both side locations. - centering are located at a greater distance from the center of the coordinate system 33, the distance from it to the lower i centering element is smaller. A lower 5 - LII centering element can be located near the coordinate system
