Abstract

The invention relates to instrumentation, in particular to the manufacture of frame structures for electrical and radio equipment. The purpose of the invention is to expand the functionality of the joint, as well as reduce the labor and material costs of manufacturing the bracket. The device contains support and pressure parts, a core with technological holes, installed with a gap, which is filled with hardening material. New in the device is that the supporting and clamping parts are made in the form of half-molds, which mate with the rod and with each other along several mutually perpendicular surfaces and cover the rod on the outer and inner sides, and an insert is installed in the half-form bracket and to coordinate the half-form relative to each other, the gap between the half-forms, the rod and the insert has the configuration of the bracket. 3 il.

Description

The invention relates to instrumentation, in particular to the manufacture of frame structures for electrical and radio equipment.

The purpose of the invention is to expand the functionality of the joint, as well as reduce the labor and material costs of manufacturing the bracket.

FIG. shows the proposed device for connection; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The core bar 1 is made with technological openings 2, a device is installed on it for connection with a bracket, which consists of half-molds 3 and 4, covering the core on the external and internal sides, insert 5 is inserted into the half-form, molten metal is poured another any or softening material forming the bracket 7.d J

The device works as follows.

The half-molds 3 and 4 mate with the rod 1 and between themselves on several mutually perpendicular surfaces and cover the core on the outer and inner sides, after which an insert 5 is installed in the half-molds 3 and 4 to form the hole in the bracket and coordinate the half-forms 3 and 4 with respect to one another, through the opening 6, the molten metal or some other material is poured in, which, filling the gap between the molds 3 and 4, the rod 1, the holes 2 in the rod and the insert 5, forms after hardening the bracket 7 and provides A. Prefabricated connection of the bracket 7 with the rod 1. Thus, the formation of the bracket during the connection with the rod reduces the labor and material costs associated with the manufacture of the bracket and assembly work on its connection C5 N3 N5

WITH

it is a C6 rod and allows to obtain a connection with minimal overall dimensions.
