Abstract

The invention relates to the field of engineering, in particular to the tooling used when drilling holes. The aim of the invention is to increase the machining accuracy by increasing the fixing accuracy of the workpiece when drilling several holes in one installation. The device consists of a housing 1 in which a clamping device is mounted on a radial bearing 2. On the axis 4 of the clamping device there is a rigidly separating disk 6, made in the form of a ratchet with a number of teeth 10 corresponding to the number of bores of the workpiece 26, on the cylindrical neck 7 of the separating The disk 6 is freely mounted to the rocker 8, on which is attached a pawl, interacting with the teeth 10, filled on the separating disk 6. At the end of the scenes 8 there is a cam groove for interacting with the stop 18 conical locking 16, the hole under which is made in the separating disc 6 and the housing 1. When turning the knob 8 from itself, the conical locking 16 is pulled out of the orifice (socket) 20 due to the fact that the stop 18 is conical. (Lefl ff / J JJJ with y with d SP tpl / f.2

The jig for drilling holes consists of a housing 1, in which a clamping device 3 is mounted on the radial bearing 2. On the axis 4 of the clamping device 3 a separating disk 6 is mounted on the key 5, made in the form of a ratchet with a number of teeth corresponding to the number of drilled parts. On the cylindrical neck 7 of the separating disk 6, a freely mounted link 8, on which is fixed a pawl 9, which interacts with the teeth 10, is formed on the separating disk 6. The rotation of the link 8 is carried out from the handle 11.

From the axial movement, the separating disk 6, together with the slide B, is held by the nut 12 and the lock nut 13. Between the separating disk 6 and the body 1, a plate 14 is mounted rigidly connected to the body 1.

The dividing disc 6 and, consequently, the clamping device 3 is fixed by a ball latch 15 (preliminary) and a conical latch 16 (finally). A conical latch 16 is installed in the guides 17 inserted in the housing 1 and the stop 18 in the cam groove 19, performed at the end of the scenes 8,

together with him and zazh: immense fixture with part 26 fixed in it rotates at a predetermined angle. When the handle 8 of the slide 8 is turned towards itself, the conical clamp 16 moves into the hole (socket). 3 il.

the socket 20 (hole) for the conical retainer 16 is made in the separating disk 6 and the housing 1, the axis of which lies in the plane of the disk connector and the housing.

Plate 21 with conductor sleeves 22 is made folding and installed in the housing 1 with the axis 23.

If necessary, using the rotary cam 24, the base of the housing 1 of the conductor is installed in a plane at an angle to the drilling axis.

In the fixture 3, there is a prism 25, which serves to hold the part 26, pushed to the prism 25 by a screw 27, at one end of which is punched with 28 knurled, and at the other end there is a hole for the handle.

To orient the part 26, there is a latch 29, pressed by the spring 30.

The conductor operates as follows.

The workpiece 26 is inserted into the clamping device 3 and is screwed to the prism 25 with the aid of a screw 27. The part is oriented by the clamp 31 pressed by the spring 32. After drilling the hole, the clamping device 3 with the part 26 is rotated to the next position 35 as follows .

When the handle 11 of the scenes 8 is rotated from itself, the conical latch 16 is pulled out of the hole (socket) 20 due to the fact that the stop 18 attached to the conical latch 16 is -; interacts with the cam groove 19, made at the end of the wings 8. With the subsequent rotation of the handle 11

side, engages with one of the teeth 10 of the pitch disc 6 and rotates the latter, and with it the clamping device 3c with the part 26 fixed in it at a predetermined angle. The rotation ends with the fixation of the dividing disc 6 with a ball lock.

Then the knob 11 of the link 8 is turned towards itself and the cam support surface of the groove 19 of the link 8, which is made with a spiral rise, moves the conical clamp 16 into the hole (socket) 20.
