Abstract

The invention discloses a self-centering spring clamping device which comprises an elastic collet body, a sliding conical sleeve and a locking nut. A clamping portion of the elastic collet body is sleeved with the sliding conical sleeve, and the sliding conical sleeve can slide up and down along the clamping portion. The locking nut is in threaded connection with the elastic collet body and used for pushing the sliding conical sleeve to slide. The locking nut is located below the sliding conical sleeve. A self-centering center is fixedly arranged inside a clamping hole of the elastic collet body. The self-centering spring clamping device is simple in structure, novel and reasonable in design and convenient to install and use, the problems that an existing shaft type gear is not convenient to machine and install and long in adjustment time and wastes time and labor during adjustment are solved, self-centering of the shaft type gear can be conveniently achieved, the clamping precision of the shaft type gear is high, and the machining precision of the shaft type gear can be ensured.

Description

technical field [0001] The invention belongs to the technical field of machine tool processing, and in particular relates to a self-centering spring clamping device. Background technique [0002] For the processing of shaft gears, the shaft diameter of the shaft gears is too large or too small and the length of the shaft, etc., will cause the shaft gears to be clamped on the machine tool for processing, and the grinding wheel cannot be punched out of the tooth groove, resulting in the gears not being able to be precisely Processing or processing clamping is difficult. Therefore, the machining of shaft gears usually requires transition sleeves to fix the shaft gears on the machine tool for processing. During specific processing, one end of the transition sleeve and an end of the shaft gear are fixed, the other end of the transition sleeve is fixed on the collet of the machine tool, and the other end of the shaft gear is tightly fastened on the tailstock top of the machine to...
