Multi-purpose clamping device for laser transmission welding

Abstract

The invention belongs to the field of a laser transmission welding and relates to a multi-purpose clamping device for the laser transmission welding. The multi-purpose clamping device comprises a base, an upper pressing plate, a pressure display screen, a moving plate, a base plate and a spring. According to sensors on the upper faces of the base, the moving plate and the base plate, the multi-purpose clamping device is adjusted by adjusting nuts, the pressing force is effectively controlled, the stress is uniformed, and the quality of machined workpieces is improved. Through the adjustment of the pressing force, the overall strength and rigidity of weldments are improved. The multi-purpose clamping device is mainly used for connecting T-shaped connectors between thermoplastic plastic or between the thermoplastic plastic and metal materials, and the gap between the adjusting base and the moving plate can be adjusted according to the thickness of a lower workpiece. Four corners are pressed equally through the adjusting nuts, and therefore the welding quality is guaranteed. Laser transmission overlap welding is also achieved when the base and the moving plate make contact in a seamless mode in perpendicular direction after the spring and the base plate are removed.

Description

Technical field [0001] The invention belongs to the research field of laser transmission welding, and specifically relates to a multi-purpose laser transmission welding clamping device. Background technique [0002] Plastic products have the advantages of light weight, high strength, low density, low cost, excellent elasticity, and corrosion resistance. Therefore, plastics are used more and more widely, especially thermoplastics. Most thermoplastic products are molded products. Due to the influence of injection molding, extrusion processing technology and mold making, many plastic products with irregular shapes or complex structures are difficult to injection mold at a time. Usually the most economical and effective method is Combining multiple simple injection molded parts together, therefore, a variety of thermoplastic connection methods have emerged. The traditional mechanical connection method is not widely used due to the shortcomings of easy damage to components, weak conn...
