Small-diameter inner hole machining technology and equipment thereof

Abstract

The invention discloses a small-diameter inner hole machining technology and equipment thereof, and relates to the technical field of machining. The small-diameter inner hole machining technology comprises the following process steps: selecting a cylindrical milling cutter which is used for a milling machine and has cutter lines on the side wall, and mounting the milling cutter on a cutter holder of a lathe through a reducing sleeve, wherein the diameter of the milling cutter is equivalent to that of the inner hole; opening two symmetrically-arranged main clamps through a main adjusting assembly, and placing a workpiece with an inner hole to be machined between the two main clamps; aligning the to-be-machined position of the workpiece to the milling cutter, and adjusting the positions of the main clamps through the main adjusting assembly so that the two main clamps can clamp the workpiece to achieve preliminary fixing; and further fixing the workpiece by an auxiliary clamp adjusting the proper position through an auxiliary adjusting assembly. The equipment can be suitable for clamping workpieces in different shapes and is high in stability, meanwhile, the milling cutter for a milling machine replaces a turning cutter, and cutter vibration during machining can be effectively avoided.

Description

Technical field [0001] The present invention belongs to the technical field of mechanical machining, particularly to a small pore diameter is within the processing technology and equipment, the small aperture hole machining workpieces major role. Background technique [0002] In machining a workpiece, the inner hole machining small aperture is a common means of processing, the operation, the staff will work fixing jig of a lathe and rotated by a motor to drive the rotating jig, the workpiece simultaneously driven by the air cylinder turning the direction of feed, hole drilling, however, there are the following conventional lathe workpiece deficiencies small aperture hole processing: [0003] 1. bore prior to processing small aperture holding means, the holding ability is poor, unable to meet the different shape of the workpiece holder, in particular for the elongated dimension of the workpiece, conventional clamping means can not achieve a firm and stable clamping; [0004] 2. Wh...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing clamping device for small-diameter inner hole processing has poor clamping ability and cannot meet the clamping of workpieces of different shapes. Especially for long-sized workpieces, the existing clamping device cannot achieve firm and stable clamping;

[0004] 2. When the existing turning tool for machining small-diameter inner holes is fixed on the lathe for work, because the handle is arranged in a rectangular strip shape, and the knife grain is only installed on one side of one end of the rectangular strip body, during processing, the turning tool The whole knife is prone to vibration, which affects the processing speed;
