Three-spot welding device

Abstract

The invention relates to the technical field of welding and particularly relates to a three-spot welding device. The device comprises a fixing bottom plate, a lifting servo motor, a coupler, a bearing block, a lifting unit, a rotation servo motor and a working rotation disc. A square column is formed integrally on the fixing bottom plate, the working rotation disc is arranged at the top end of the square column, the lifting unit is arranged on one side of the square column below the working rotation disc, the rotation servo motor is arranged on the lifting unit, the bearing block is fixed on one side of the square column below the lifting unit, and the lifting servo motor is arranged on the fixing bottom plate. By means of the device, an automatic position searching function of the servo motor is used, so that product diversification can be achieved, the device is applicable to production of multi-model products, the product quality is guaranteed, the production efficiency is high, welding splashes are few, the secondary machining process is reduced, the labor intensity and the production cost are reduced, and hurt to human bodies caused by harmful substances is reduced to the largest degree.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a three-spot welding equipment. Background technique [0002] Spot welding is a high-speed and economical connection method. It is suitable for the manufacture of stamped and rolled sheet members that can be overlapped, the joints do not require airtightness, and the thickness is less than 3mm. It is to weld the weldment on the contact surface of the joint. Individual spot welding; but now most of them still use manual spot welding, the joints of manual spot welding are uneven, the melting depth is not enough, the welding quality is difficult to guarantee, and the efficiency is low, the secondary processing of the product is complicated, and the workload of welding bead cleaning is large. Too much welding spatter. [0003] And the spot welding machine of prior art, although the efficiency height than artificial spot welding, mostly exists welding time-consuming long, the qualit...
