Clamping device for processing external diameter groove of thin-wall tubular part

Abstract

The invention relates to a clamping device for processing an external diameter groove of a thin-wall tubular part. The device comprises a three-jaw chuck, and is characterized in that: an expansion core is arranged at the axle center position of the three-jaw chuck; three groups of centering rods are uniformly arranged on the circumference between the expansion core and a claw of the three-jaw chuck; a tapered thread section is arranged at the front end of the expansion core and is engaged with the front ends of the three group of centering rods; and a workpiece clamping position is formed between the centering rods and the claw of the three-jaw chuck. The device has a scientific and reasonable structural design, the clamping accuracy, reliability and stability of the device can be effectively ensured, and the deformation amount of a workpiece is controlled to the lowest extent, so that the processing accuracy of the workpiece is ensured, and the requirement of processing the external diameter groove of the thin-wall tubular part is met.

Description

technical field [0001] The invention belongs to the field of mechanical processing devices, in particular to a device for processing and clamping outer diameter grooves of thin-walled tubular parts. Background technique [0002] When processing the outer diameter groove of thin-walled tubular parts, it is necessary to clamp the parts. Due to the characteristics of thin wall thickness of the parts, ordinary fixtures, whether internal expansion or external clamping, will cause excessive clamping force. Or the clamping force is uneven, resulting in the deformation of thin-walled tubular parts, which cannot guarantee the accuracy of the workpiece at all, resulting in the scrapping of the workpiece. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a thin-walled tubular part outer diameter groove processing clamping device that can effectively control the amount of deformation and ensure the proc...
