Spot welding clamp with preheating function and hooks

Abstract

The invention discloses a spot welding clamp with a preheating function and hooks, and belongs to the field of spot welding clamps. The spot welding clamp comprises a pair of clamp forceps, a positioning device, a base, two supporting plate and a positioning plate, wherein the pair of clamp forceps is arranged on one side of the upper surface of the base; the two supporting plates are respectively positioned on the two sides of the lower surface of the base; the positioning device is arranged on one side of the upper surface of the base; the positioning plate is positioned in the center of the upper surface of the base; the clamp further comprises an eddy heater and the hooks; the eddy heater is fixed in the center of the lower surface of the base; the hooks are fixed on the side surface of the base. When the clamp is used, a worker can directly heat a workpiece, the welding can be performed just after the heating, the operation is convenient, and the cost is reduced; meanwhile, the worker can hang various tools needed in the operation process on the hooks, the taking and the use are convenient, the design is attractive and elegant, safety hazards to the production can not be generated, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of spot welding fixtures, and in particular relates to a spot welding fixture with a preheating function and a hook. Background technique [0002] Spot welding is a high-speed, economical joining method. It is suitable for the manufacture of stamped and rolled thin plate components that can be overlapped, the joints do not require airtightness, and the thickness is less than 3mm. It is to weld the individual points of the weldment on the contact surface of the joint. Spot welding requires the metal to have good plasticity. The spot welding electrode is an important part to ensure the quality of spot welding. Its main functions are: (1) conduct current to the workpiece; (2) transmit pressure to the workpiece; (3) rapidly dissipate the heat in the welding zone. Spot welding is usually divided into two categories: double-sided spot welding and single-sided spot welding. During double-sided spot welding, the electrode...
