Problems solved by technology

The advantage of using this spot welding process is that the fixture design is simple. The problem is that the welding process requires two times of clamping and positioning, and two times of welding, resulting in poor positioning accuracy, low welding efficiency, and high labor intensity, which restricts the qualification of the product. Product rate improvement

Embodiment

[0027] The invention is applicable to the positioning fixture for relay armature combination spot welding. The invention distributes two shaft fixing pieces of the relay armature combination shaft symmetrically on the two surfaces of the relay armature, and is clamped and positioned by the invention.

[0028] Concrete clamping process of the present invention is as follows:

[0029] Refer to figure, figure 2 , image 3 Place the relay armature together with the shaft fixing piece in the cavity of the clamp body 1, and make the two sides of the shaft fixing piece face the upper and lower pressing mechanism 2, and push the relay armature and the shaft fixing piece into the two pressing blocks of the upper and lower pressing mechanism 2 24, the shaft fixing piece touches the two pressing blocks 24 of the upper and lower pressing mechanism 2, and the pressing block 24 together with the pressing block sleeve 23 overcomes the elastic force of the first spring 22 to open; at the sa...

Abstract

The invention discloses a fixture for combined spot welding of relay armatures. The fixture comprises a fixture body, a vertical pressing mechanism, a front side pressing mechanism and a lateral facepressing mechanism. The vertical pressing mechanism, the front side pressing mechanism and the lateral face pressing mechanism are arranged on the fixture body, the vertical pressing mechanism implements vertical positioning, the lateral face pressing mechanism implements lateral positioning, and the front side pressing mechanism implements forward positioning as well as final fixing, so that clamping and positioning of the relay armatures and two-sided shaft fixing pieces are automatically completed finally. Through cooperation of the fixture and a double-end spot welding machine, spot welding is conducted on the two-sided shaft fixing pieces and the relay armatures at the same time. The fixture for combined spot welding of the relay armatures has the advantages that clamping is convenient, positioning is reliable, the consistency of the two-sided shaft fixing pieces is good, the work efficiency is high, and the precision of products subjected to spot welding is greatly improved.

Description

technical field [0001] The invention relates to the technical field of relay welding fixtures, in particular to a relay armature set [0002] Fixtures for spot welding. Background technique [0003] The combined shaft of the relay armature has two shaft fixing pieces, which are symmetrically distributed on both sides of the relay armature. Due to the defects of the fixture, the shaft fixing piece in the prior art can only be welded on one side, that is, the clamping point is installed first. Weld one side of the shaft fixing piece, after the spot welding is completed, turn it over for the second clamping and then spot weld the other side of the shaft fixing piece. The advantage of using this spot welding process is that the fixture design is simple. The problem is that the welding process requires two times of clamping and positioning, and two times of welding, resulting in poor positioning accuracy, low welding efficiency, and high labor intensity, which restricts the qual...
