Abstract

The invention relates to metal working and in particular to universal devices for processing systems of alternating holes. The aim of the invention is the expansion of technological capabilities. The conductor plate is made in the form of a cylindrical ring 1 with a circular groove 2 and mounted on it with the possibility of rotation of the hinged dies. Each link 5 of the multilink consists of a pair of plates 6 with a central groove 7 and mounted in the last pair of sliders 96 with holes for interchangeable conductor sleeves 8. The axle of the multiple link consists of conductor holes 8 mounted in the holes of the sliders and fixed by retaining rings . The gaps between the links of the multi-link form additional guides for tools. In the embodiment of the conductor design, in the absence of fixing screws, bevels are made on the side surfaces of the sliders 9 for connecting them with an additional common fixture mounted on each of the links of the multi-link. Adjustment of the device is carried out according to the standard. After loosening the locking screws 10, the conductor sleeves 8, together with the sliders 9, are able to move simultaneously in two directions along the slots of the plates 6 of each multi-link. Then, loosening the bolts 3, they are moved along the circular groove 2 of the ring 1, thereby adjusting the axial distance of the conductor sleeves 8. After that, the locking screws of 10.2 C are fixed. clamp rod

The invention relates to metal working, in particular, to universal devices for processing systems of alternating holes.

The aim of the invention is the expansion of technological capabilities due to the stepless adjustment of the coordinate position of each conductor sleeve in their common conductor plate, and the conductor plate itself relative to the housing

Conductor sleeves 8 are fixed with locking rings 11 {fig. 8 and 4). In addition to the south, the gaps 12 each of the links of the 5 link form additional guides for the tools, in which, if necessary, additional conductor bushings can be installed (Fig. 9). The adjustment of the device is carried out according to the standard). To adjust the processing of a specific group of parts having corresponding systems of alternating holes, the locking screws 10 (Fig. I and 3) are loosened, while the conductor sleeves 8, together with the crawl piece 9, are able to move simultaneously in two - the directions along the slots of the plates 6 of each link are many pennic. Then, loosening the bolts 3, they will be mixed in a circular groove 2 of the ring 1 (fig. 10), in connection with this, the head changes between the edges 1537405

the links of the multisite. Due to this, adjustment of the center distance of the conductor bushings is carried out both in one row and between their rows. After that, the locking screws 10 are fastened.

Next, adjust the position of the axes of the system of conductor sleeves 8 relative to the ring 1. To do this, without changing the relative position of the links 5, the entire multi-link is turned relative to the fixed ring 1. After that, the bolts 3 are fixed. Thus, the device is configured for machining parts with a system of alternating holes with a central hole. For machining a part with a system of alternating holes without a central hole, the tools are guided either directly along additional guides formed by the base surfaces of the mash i 6 links IJ, 1 either by conductor, /: sleeve;, m set in these gaps 12 (in ,. 9).

To tune in to the processing of another system of alternating holes, differing in diameter, the holes are replaced: approx. 8.
