Description

Longitudinal Quick Clamping Device for Friction Stir Welding Welding Workpiece

technical field

The utility model belongs to the field of mechanical processing, in particular to a longitudinal fast clamping device for friction stir welding workpieces.

Background technique

At present, when using welding tooling to weld and fix parts longitudinally, the method of installing a curved Kalan fastening device on the positioning tool or using a large weight to directly press on the workpiece has the following disadvantages: The curved Kalan fastening device must be manually fastened by the operator according to the position of the workpiece; the fastening method is clumsy, and the torque wrench is used to add force; because the operator manually fastens, the working time is long.

Contents of the invention

The utility model provides a fast vertical clamping device for friction stir welding welding workpieces to solve the problem that the existing manual fastening device adopts a pressing iron to directly receive force manually and has a long working time.

The technical scheme of the utility model is: the bottom plate is welded with the bottom fixing frame, three support plates are fixedly connected with the bottom plate, the welding groove is fixedly connected with the support plate, 10 sets of adsorption devices are installed on both sides of the welding groove, and are connected with the bottom The plate is fixedly connected, there is a suction cup above the adsorption device, 3 sets of vertical fast clamping blocks are fixedly connected with the bottom plate, the horizontal fixed plate and the bottom support plate are respectively fixedly connected with the support plate, the base is installed on the support plate, and the fixed seat is fixed with the base Connection, the pneumatic cylinder is installed on the supporting beam through the mounting hole, the supporting beam is installed on the supporting vertical beam, the supporting beam and the supporting vertical beam are closely matched through the fastening pin, the supporting vertical beam is connected with the support, and there is a pneumatic joint on the pneumatic cylinder .

The utility model has the advantages of novel structure, which changes the original way of only using manual fastening device, but adopts pneumatic control of air compressor, fast and firm clamping speed, greatly improves labor efficiency and reduces cost. It used to take 30 minutes to clamp a 3-meter-long friction stir welding workpiece, but now it only takes 6 minutes, which greatly shortens the clamping time of the work.
