Clamping mechanism for welding bolts

Abstract

The invention provides a clamping mechanism for welding bolts. The clamping mechanism includes a limiting block, and the left part of the limiting block stretches forward to form a clamping part; an opening groove is formed in the middle of the interior of the clamping part, and the opening groove is forward internally provided with two manganese steel spring pieces, wherein the two manganese steel spring pieces are arranged in a V shape; the welding bolts are inserted into the front sides of the middles of the two manganese steel spring pieces and are clamped; and the head parts of the welding bolts are located below the clamping part; pressing blocks are arranged on the front sides of the welding bolts, and the pressing blocks can press the head parts of the welding bolts downwards. During welding, the welding bolts are stuffed into the front sides of the middles of the two manganese steel spring pieces which are arranged in the V shape, and grooves are formed to allow the welding bolts to pass through, in this way, it can be ensured well that the welding bolts are clamped in place and cannot fall off, and then clamping force is exerted on the welding bolts through the pressing blocks, so that the functions of clamping and fixing to the welding bolts are achieved, and the perpendicularity of the welding bolts is ensured to make the welding bolts be suitable for production.

Description

technical field [0001] The invention relates to the field of clamping of welding bolts, in particular to a clamping mechanism of welding bolts. Background technique [0002] Welding process is a common manufacturing process of automobile body frame, among which bolt welding is a commonly used method on automobile body frame parts. At present, in the welding process, it often occurs that the clamping is not in place and the production efficiency is affected by repeated assembly, or the verticality cannot meet the requirements. Therefore need a kind of clamping in place, and satisfy verticality. Therefore, it is very important to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a clamping mechanism for welding bolts. During welding, the welding bolts are inserted into the middle front side of two manganese steel spring pieces arranged in a V shape, and grooves are provided for the welding bolt...
