Welding positioning device for capacitor outer shell of electric automobile

Abstract

The invention discloses a welding positioning device for a capacitor outer shell of an electric automobile. The welding positioning device comprises a mounting plate, the mounting plate is fixedly connected with a first check block used for limiting a welding workpiece bottom plate, the mounting plate is fixedly connected with a limiting column, and the limiting column is used for limiting the rear side of a workpiece; supporting rods are fixedly connected to the two sides of the mounting plate, a supporting plate is fixedly connected to the supporting rods, a first linear driving device is fixedly mounted on the supporting plate, a first linear driving shaft which drives up and down is arranged at the lower end of the first linear driving device, and the first linear driving shaft penetrates through the supporting plate and is connected with a first guide clamping mechanism; and the first guide clamping mechanism is used for clamping a to-be-welded outer shell at a relative position on the bottom plate. According to the welding positioning device, the workpiece can be conveniently guided, positioned and clamped, so that the workpiece can be conveniently welded, and the welding efficiency and the welding precision are improved; and the structure is simple, and welding slag can be prevented from affecting positioning accuracy.

Description

Technical field: [0001] The invention relates to the technical field of auxiliary manufacturing of capacitors, in particular to a welding positioning device for electric vehicle capacitor shells. Background technique: [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. [0003] A capacitor, usually referred to as a capacitor for its ability to hold charges, is a device that holds charges; it is composed of an insulating dielectric sandwiched between two metal electrodes. When a voltage is applied between two metal electrodes, charges are stored on the electrodes, so capacitors are energy storage elements. Automotive capacitors, also known as electrochemical capacitors and electric double-layer capacitors, are a new type of capacitor. Its appearance makes the limit capacity of the capacitor rise suddenly. [0004] In the r...

AI Technical Summary

Problems solved by technology

The existing automobile capacitor shell is generally welded on the bottom plate of the flat plate with a bent C-shaped section shell, and the leakage on both sides of the bottom plate forms a flange for fixing. During the welding process of the capacitor shell, the existing method Manual spot welding is used to fix first, and then continuous welding to weld the shell to the bottom plate. This kind of welding has low efficiency and cannot meet the production capacity requirements.
