Abstract

The invention discloses a simple elastic collet chuck which solves the problem in the existing collet chucks of being complex in structure. The collet chuck comprises a cylinder and a collet chuck body. An expanding sleeve is arranged at one end of the cylinder, the inner wall of the expanding sleeve is conical, the collet chuck body is attached to the inner wall of the expanding sleeve, sliding grooves are formed in the inner wall of the expanding sleeve and the outer wall of the collet chuck body, guiding pins are arranged in the two sliding grooves, the end portion of the collet chuck body is connected with one end of a cylinder piston, the other end of the cylinder piston rod is connected with a collet chuck pull rod, and a clamping adjusting nut is arranged on the collet chuck pull rod. The simple elastic collet chuck is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to machining technology, in particular to a simple elastic collet. Background technique [0002] The collet is a device for clamping small-diameter tools to the end of the spindle, and is mainly used in automatic lathes. The existing collet generally has a complex structure, cannot realize fast clamping and loosening actions, and has low work efficiency, and is not suitable for processing small batches of workpieces. Contents of the invention [0003] The invention provides a simple elastic collet to solve the problem of complex structure existing in the existing collet. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: [0005] A simple elastic collet includes a cylinder and a collet. A tension sleeve is provided at one end of the cylinder. The inner wall of the tension sleeve is tapered, and the collet is attached to the inner wall of the tension sleeve...
