Spot welding clamp for automobile parts

Abstract

The invention belongs to the technical field of automobile part welding appliances, and particularly relates to a spot welding clamp for automobile parts. The spot welding clamp for the automobile parts comprises a bottom plate, a worktable is slidably arranged on the bottom plate, and the worktable is connected with a worktable air cylinder; an anti-missing strip penetrates through a sliding groove and then is arranged on a sliding sleeve, and an anti-missing inductor is arranged on the position, located below the anti-missing strip, on a left clamping plate and a right clamping plate; an anti-sliding boss is arranged on the position, located on one side of a material trough, of the left clamping plate and the right clamping plate; and an anti-sliding elastic piece is arranged on the anti-sliding boss. The spot welding clamp for the automobile parts has the beneficial effects that whether the parts are loaded in missing and wrong modes or not can be identified, the mistake-proofing, anti-missing and anti-sliding functions are achieved, automatic clamping is realized, automatic returning is achieved after welding is finished, manual power is only required to conduct discharging, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of welding tools for auto parts, in particular to a spot welding fixture for auto parts. Background technique [0002] In the welding of auto parts, most of them use manual welding at present, especially for the spot welding of pipe fittings. Due to the special shape of the pipe fittings, when welding, the pipe fittings first need to be clamped and positioned. Therefore, at present, there are preliminary fixtures for positioning when performing manual welding. This kind of fixture structure is generally relatively simple, including two splints, and a material groove is formed between the two splints, and then welding is performed. There are defects in this kind of welding method: first, it is easy to install wrong parts when welding, and weld two irrelevant parts; second, it is easy to miss parts, which affects the efficiency; When the parts are clamped too tightly, it is easy to damage the surface of the p...

Problems solved by technology

There are defects in this kind of welding method: first, it is easy to install wrong parts during welding, and weld two irrelevant parts; second, it is easy to miss parts, which affects the efficiency; third, when welding When the parts are clamped too tightly, it is easy to damage the surface of the parts. If the clamp is loose, it is easy to slide during welding, which will affect the welding effect
