Bending plate chain link automatic welding equipment

Abstract

The invention discloses automatic welding equipment for chain links of a bent plate chain. Three installing and clamping devices for installing and clamping workpieces are arranged on a rotating base plate, and two welding guns are arranged on a machine fame and are used for respectively welding combining parts of chain plates at two side and a sleeve, so three processing stations are formed, one station is used for dismounting and mounting the workpieces, one station is used for welding the chain plate at one side and the sleeve, so the other station is used for welding the chain plate at the other side and the sleeve, so the cyclic circulation of the installing and clamping devices for installing and the clamping the workpieces among the three stations can be realized, the one-step installing and clamping can be realized, the flow line welding is realized, the welding speed is high, and the production efficiency is high. The automatic welding equipment has the advantages that the chain plates at two sides and the sleeve only need to be installed and clamped in one step, the welding of the chain plates at the two sides and the sleeve can be realized through the rotation of the base plate, and the flow line welding operation of simultaneously carrying out welding and installing and clamping can be realized.

Description

technical field [0001] The invention belongs to the technical field of chain manufacturing equipment, and in particular relates to an automatic welding equipment used for welding chain links of bent plate chains. Background technique [0002] At present, the amount of bent plate chain is relatively large, and the bent plate chain is mainly composed of welded chain links connected in series through connecting pins, such as figure 2 As shown, the bent plate chain link is formed by welding and fixing the chain plates 22, 23 on both sides and the sleeve 21 in the middle. Publication Nos. CN103769791A and CN201264068Y each disclose a welding device for a bent plate chain link. Two welding torch heads are simultaneously inserted between the chain plates on both sides of the bent plate chain link for synchronous welding. Such a structure is only suitable for welding sleeves Longer length bent plate chain. In the prior art, for the welding of curved plate chain links with shorter ...

AI Technical Summary

Problems solved by technology

In the prior art, for the welding of curved plate chain links with shorter sleeves or smaller chain links, two welding torches cannot be accommodated for simultaneous welding, so only traditional welding can be used, that is, only one side of the chain plate can be welded first And the sleeve, and then manually replace the position, and finally weld the other side of the chain plate and the sleeve, which requires a lot of labor and low production efficiency

[0003] In addition, the welding device disclosed in the above patent documents also has problems such as time-consuming manual clamping operation, low clamping positioning and rotation accuracy, low utilization rate of welding equipment, and low production efficiency.
