Abstract

A fixture for shaft part axial hole automatic positioning comprises a front positioning and clamping mechanism, a tail ejecting mechanism and a bottom plate. The bottom plate is a rectangular plate, and the front positioning and clamping mechanism and the tail ejecting mechanism are fixed to the two ends of the bottom plate; the front positioning and clamping mechanism comprises a baffle, a baffle ejector pin and a bush; a rotary hole is formed in the middle of the baffle, the top of the baffle is provided with a positioning hole, and a spring is arranged in the positioning hole; a rotary shaft at one end of the baffle ejector pin is matched with the interior of the rotary hole, and more than three ball holes are distributed in the circumference of the end face of a round plate at the other end of the baffle ejector pin; a positioning ball is arranged at the outer end of a spring in the positioning hole, and part of a ball body of the positioning ball extends into one of the more than three ball holes; the other end face of the round plate is provided with a pin hole and a centre; the bush is fixed to the round plate through a fixing plate, and an annular elastomer is arranged on the edge of the round hole; the tail ejecting mechanism comprises a tailstock base, a tailstock ejector pin and a handle; the tailstock ejector pin is arranged in the middle of the tailstock base, a screw rod is arranged at the outer end of the tailstock ejector pin, and the extending end of the screw rod is connected with a rotary handle in a matched mode.

Description

technical field [0001] The invention belongs to the field of mechanical processing tooling, in particular to a fixture for automatic positioning of axial holes of shaft parts. Background technique [0002] The machining of small radial holes in shaft parts has always been difficult, especially for several rows of holes in the axial direction, which need to penetrate the axial holes and radial holes, making clamping and positioning difficult. V-shaped block support and positioning device is usually used now. The front end is limited by the end face of the baffle, and the rear end is firmly supported by a thimble. pin positioning; [0003] The existing positioning device has the following problems: (1), the front end of the workpiece only relies on the friction between the end surface of the workpiece and the front baffle to constrain the workpiece, and then supports the workpiece with a V-shaped block, which cannot be fixed only by the friction between the front baffle and t...
