A multi-degree-of-freedom and multi-angle rocker-arm spot welding machine

Abstract

The invention discloses a multi-degree of freedom and multi-angle rocker arm type spot welder. The spot welder comprises an engine base, wherein a stand column component is installed on the engine base, a cross arm is installed on the side wall of the upper portion of the stand column component, a sleeve perpendicular to the cross arm is installed at the tail end of the cross arm, an upward support pillar is fixedly installed on the sleeve, a support seat is installed on the upper end of the support pillar in a sliding mode, outer supports arranged horizontally and symmetrically are installed in front of the support seat and in back of the support seat respectively, an upper clamp and a lower clamp arranged coaxially are installed between the opposite inner walls of the outer supports in a rotary mode, an inner support is fixed on the tail end of the upper clamp, a pushing rod is arranged in the middle of the inner support, a tail end of the pushing rod is installed on the inner support in a rotary mode, and the front end of the pushing rod and the tail end of the lower clamp are installed in a rotary mode; an upper spot welding head and a lower sport welding head arranged oppositely are installed at the front ends of the upper clamp and the lower clamp respectively. According to the multi-degree of freedom and multi-angle rocker arm type spot welder, motions with multi-degree of freedom directions are achieved, metal plate structures with different angles can be welded, clamping is achieved at a time, consistency of welding quality is guaranteed, labor intensity of operating personnel is lowered, and work efficiency is improved.

Description

technical field [0001] The invention relates to a welding machine, in particular to a multi-degree-of-freedom and multi-angle rocker-arm spot welding machine. Background technique [0002] The spot welding machine is a device that uses the resistance heat generated by the current passing through the contact surface of the joint and the adjacent area to weld, so the spot welding method is also called resistance welding. In the prior art, the welding head of the resistance welding equipment is generally divided into three categories: one is to clamp the workpiece by manually manipulating the pedal mechanical device to move the electrode; the other is to use the cylinder or hydraulic device to drive the mechanical device to move the electrode; the third is to The servo electrode is used to drive the mechanical device to move the electrode. The rocker welding machine proposed by the present invention belongs to the use of a cylinder or a hydraulic device as a power source to dri...

AI Technical Summary

Problems solved by technology

[0003] Traditional resistance welding equipment can usually only move up and down, and can only be used for sheet metal structures with relatively regular welder profiles or small angles. For sheet metal structures with complex profiles and large angles, usually It is necessary to manually readjust the fixed angle before welding. Due to the limitation of the welding structure and multiple clamping, it has the disadvantages of low work efficiency, high work intensity of the operator, and poor consistency of welding quality.
