Abstract

The invention relates to a composite freezing clamping device. Thedevice adopts a composite refrigeration method combining semiconductor refrigeration and vortex tube refrigeration. The surface of a workbench of the device is provided with an adhesive layer, and a to-be-processed workpiece is placed on the adhesive layer; when clamping is carried out, a semiconductor refrigeration sheet is electrified with direct current, a Peltier effect occurs, the temperature of the workbench is gradually reduced, the adhesive layer is solidified, the to-be-processed workpiece is clamped, anda vortex tube refrigerator is in a refrigeration state; when unloadingis carried out, the semiconductor refrigeration sheet is powered off and enters a closed state, the vortex tube refrigerator is in a heated state, hot gas is output to heat the workbench, the adhesive layer is thawed, and the to-be-processed workpiece is unloaded. The composite freezing clamping device has the advantages that the refrigerationspeed is fast, the refrigeration effect is good, the adjustability is high, the structure issimple, and the maintenance iseasy.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a composite freezing clamping device. Background technique [0002] One of the traditional clamping methods in cutting processing is fixture clamping. The degree of clamping deformation and springback deformation is closely related to the actual clamping layout, and the resulting processing deformation is more obvious; another more traditional clamping method is Vacuum adsorption, the clamping force is relatively uniform, but the clamping stress is inevitably introduced, and the workpiece will have a certain degree of rebound deformation after processing. Therefore, for the clamping in the cutting process, it is urgent to find a new clamping mechanism and method, which can significantly reduce the deformation caused by the clamping. [0003] Different from the traditional fixture clamping, vacuum suction cup and other fixing methods, the freezing clampi...
