Abstract

The invention discloses an airbag type compression device which comprises a base, a pressing plate, an airbag and a round pin. The pressing plate is arranged on the base, a space for containing a workpiece is formed between the base and the pressing plate, the round pin is fixed on the base, one end of the pressing plate is hinged on the base, a locking plate is hinged at the other end of the pressing plate, a slot is formed in the locking plate, an opening is formed in one end of the slot, the inner wall of the slot can contact with the round pin, a groove is formed in the inner wall of the slot, a retaining piece is arranged in the groove, a pressing spring is arranged between the retaining piece and the groove, one plane of the retaining piece facing the opening of the slot is an inclined plane, the inclined plane is inclined toward the direction far away from the opening of the slot, and the air bag is arranged on one side of the pressing plate facing the workpiece. The air bag is arranged on the pressing plate, different amounts of gas can be inflated into the air bag, so that different workpieces are pressed, different pressing plates do not need to be designed according to different workpieces, the locking plate is arranged on the pressing plate, the pressing plate can be locked through the locking plate, and a special driving device or labor for providing the clamping force is omitted.

Description

technical field [0001] The invention belongs to the technical field of devices for fastening or fixing components or machine parts. Background technique [0002] Before the workpiece is processed, the workpiece needs to be fixed and positioned to prevent the workpiece from moving during processing. The common workpiece clamping mechanism now clamps the workpiece through two opposite jaws, and provides a continuous clamping force to fix the workpiece. [0003] However, the above-mentioned structure has the following disadvantages: the setting of the jaws needs to be designed according to the shape of the workpiece, otherwise the jaws and the workpiece will be in point contact, which will easily damage the workpiece. It is necessary to provide a special driving mechanism or manpower to make the jaws have a continuous clamping force on the workpiece to ensure that the workpiece will not fall from the jaws, but the special driving mechanism and manpower clamping will inevitably...
