SU456700A1 - Device for fixing the contact springs during welding - Google Patents

Description

between the nut 13 of the rod 6 and the slide, m 14 there is a gap, and the clamps 2 protrude from the housing 1 upwards. The clamps 2 are put on the contact spring 3, and the camshaft 12 is turned on. After this, the housing 1 together with the carriage moves along the guides 16 under the action of the spring 17 until it stops 22. The contact spring 3 is installed with a small gap with the contact wire 21. With further rotation of the distributor The shaft 12, the cam 11, interacting with the roller 28, moves down the rod 26 with the fork 25, which engages the brush 6 and does not have it down.

In this case, the support 7 compresses the spring 9, and the housing 1 is pressed by the spring 10 to the lower stop 5. The lower stop 5 is adjusted so that at the moment when the case is fed into it, the contact spring 3 is pressed to the contact wire 21. The electrodes 23 and 24 are compressed, and proiz.chodit welding. Then, under the action of the cam 11, the slider 6 moves even lower, compressing the spring 9. At the same time, the body 1, having reached the lower stop 5, is already

does not lower, and the bm, moving relative to the housing 1, compresses the spring 10 like a shock absorber. to the starting position.

P | redmet invention

A device for fixing contact springs during welding, containing a corus with clamps, located on the carriage and spring-loaded from it, characterized in that, in order to increase the quality of welding of contacts to short contact springs, Kopinyc is equipped with a spring-mounted with respect to it, installed with the possibility of on the latches and rigidly connected with the support placed between the housing and the carriage, while the carriage is equipped with adjustable stops limiting the vertical movement of Kopinyca.
