Description

Clamp for welding logistics vehicle body

Technical Field

The invention relates to the technical field of welding fixtures, in particular to a fixture for welding a body of a logistics vehicle.

Background

Welding, also known as fusion, welding, is a manufacturing process and technique for joining metals or other thermoplastic materials, such as plastics, in a heated, high temperature or high pressure manner. Welding accomplishes the purpose of joining by three ways: 1. fusion welding, namely heating the workpieces to be jointed to locally melt the workpieces to form a molten pool, cooling and solidifying the molten pool to joint the workpieces, and adding a melt filler to assist when necessary, so that the method is suitable for welding various metals and alloys without pressure. 2. Pressure welding, in which pressure must be applied to a welding piece in a welding process, belongs to the processing of various metal materials and partial metal materials. 3. Brazing, namely, a metal material with a melting point lower than that of the base metal is used as brazing filler metal, the liquid brazing filler metal is used for wetting the base metal, a joint gap is filled, and the liquid brazing filler metal and the base metal are mutually diffused to realize a link weldment. It is suitable for welding various materials, and also suitable for welding different metals or different materials.

The energy sources for modern welding are many, including gas flame, electric arc, laser, electron beam, friction, and ultrasonic, among others. In addition to use in a factory, welding can be performed in a variety of environments, such as the field, underwater, and space. Wherever welding can be dangerous for the operator, appropriate precautions must be taken while welding is being performed. The possible injuries to human body caused by welding include burn, electric shock, visual impairment, toxic gas inhalation, over-irradiation of ultraviolet rays, etc.

When a vehicle body is welded, parts need to be clamped, and the clamping stability of the conventional clamping mechanism is poor, so that the welding efficiency cannot be effectively improved, and therefore, improvement is needed.
