Description

113

The invention relates to the installation of electrical wiring automation systems can be used in the manufacture of low-voltage integrated devices mainly for controlling electric drives.

The purpose of the invention is to improve the operational capabilities by providing a template adjustment to the size of the tow.

Fig, 1 shows the proposed device with adjustable combs boards, General view; figure 2 - comb-fee, bottom view; Fig. 3 shows the comb when the cylindrical surfaces of rigid and floating roller bearings run over the annular grooves of the guides; Fig. 4 is the same at the time when the conical surfaces fix the rigid and floating roller bearings in the annular grooves of the guides.

The device for the manufacture of harnesses of electrical wires includes a drum template 1 and a drive 2, Drum template 1 consists of two spaced de. 3 and 4 on the shaft 5, on the inner end surfaces of which the guides 6 and 7 are mounted, each of which has annular grooves with cylindrical surfaces 8 and 9 and conical surfaces 10 and 11; circuit boards - comb 12, each of which is mounted on a rigid 13 and floating

14 roller bearings, which are trapezoidal or cylindrical in cross section. The supports 13 and 14 have a cylindrical

15 and a conical 16 surface and rods. Floating roller bearing 14 by means of rods mounted on the holder 17, which through the spring 18 is movably connected to the pusher 19 which is spring-loaded spring 20 to the cam 21 having a helical surface 22, in the axis of the cam 21 there is a quadrilateral slot for installing a quick-release key 23,

Gear 24 is mounted on the outer end surface of one of the disks, and gear 25 is fixed on the drive. A limb of 26 dp is set on the cylindrical surface of the disk on the dimensions of the harness. Pointers 27 are riveted on combs 12,

2022

The adjustment of the dies 12 of the device for the manufacture of harnesses of electrical wires to the dimensions of the harness is performed as follows.

The quick-release key 23 is inserted into the tetrahedral nest of the axis of the cam 21, rotates clockwise, the diameter of the helical surface 22 decreases, the pusher

19 due to the action of the springs 18 and 20 is pressed against the spiral surface

22 cam 21, relieving bearings 13 and 14 from thrust. By key

5 | 23, the comb 12 is moved parallel to the axis of the drum by rolling in the cylindrical surfaces 15 of the roller bearings 13 and 14 along the cylindrical surfaces 8 of the guides 6 and 7,

0 After the first comb with pointer 27 comes out to limb 26, the key 23 is turned counterclockwise, while the cam 21 with its spiral surface 22 moves the pusher 19, the springs 18 and

20 are pressed and fixing of the comb 12 occurs by spreading it with roller bearings 13 and 14 relative to the conical surfaces.

0 10 and 11 annular grooves directed y-mjix 6 and 7. Each of the following combs in this way moves to the desired bundle size along the limb and is fixed.

The proposed device has the following advantages: it provides a quick adjustment of the template to the required dimensions of the harnesses; adjustment of the dies is provided without

40 mounting and dismounting fasteners; the versatility of the pattern is ensured by diluting the dies to any size, which makes it possible to increase the degree of use of the equipment; The process of adjusting the template is easy, and, consequently, the labor intensity is reduced.
