Chuck structure for rapidly clamping shaft workpieces

Abstract

The invention provides a chuck structure for rapidly clamping shaft workpieces, and belongs to the technical field of machinery. The chuck structure comprises a cylindrical body, one end of the body is opened, a hollow sleeve is arranged in the body, the circumferential surface of the sleeve is in threaded connection with the middle of the inner wall of the body, a spiral groove is formed in the end surface, close to the opened end of the body, of the sleeve, a plurality of guide blocks are uniformly arranged in the circumferential direction of the end surface, close to the opened end, of thebody, and a caliper is connected to the guide blocks in a sliding manner along the radial direction of the body. The caliper is provided with a plurality of thread convex ribs corresponding to the spiral grooves, the end, close to the bottom of the body, of the sleeve is provided with a step hole, the step hole is internally connected with a pressing block, a plurality of guide rods positioned atthe eccentric position of the pressing block are fixedly arranged on the pressing block, and the bottom of the body is provided with guide holes corresponding to the guide rods. The chuck structure has the advantages of being high in efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a chuck structure for quickly clamping shaft workpieces. Background technique [0002] During the processing of shaft workpieces, the workpiece needs to be clamped first. The clamping accuracy has a great influence on the machining accuracy, and the clamping efficiency has a great influence on the processing efficiency. The existing clamping tools for shaft workpieces are generally It is all realized by adjusting the clamping gap with multiple sliding calipers, and then fixing the adjusted calipers. However, the workpiece is easy to relax under the action of vibration and non-axial external force during processing, which seriously affects the processing efficiency and Precision. Contents of the invention [0003] The purpose of the present invention is to provide a chuck structure for quickly clamping shaft workpieces in view of the above-mentioned problems existing in the prio...
