Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 and figure 2 As shown, a keyway milling fixture includes a double-acting vise 10, and the double-acting vise 10 includes a clamp base 11 and a double V-shaped jaw 12 arranged on the clamp base 11, and the double-V-shaped jaw 12 can To clamp the workpiece 100, the clamp base 11 is also connected with a workpiece locator 20. The workpiece locator 20 has a rotatable positioning mandrel 21, and the shape and size of the positioning mandrel 21 are consistent with the cavity of the workpiece 100. Fittingly, when the positioning mandrel 21 is inserted into the cavity of the workpiece 100, the centerline of the workpiece 100 is positioned and fixed, and the positioning mandrel 21 can rotate along the circumferential direction of the centerline of the double V-shaped jaw 12 , that is, the processing surface of the wo...

Abstract

The invention belongs to the technique field of machinery process and relates to a milling key groove clamp. In order to solve the technique problems of the prior art that the height is adjusted while clamping the workpiece different in diameter, the work efficiency is low and the processing precision is impacted. The milling key groove clamp comprises a dual-function flat clamp, the dual-function flat clamp comprises a clamp seat and dual-V clamping opening formed in the clamp seat, the clamp seat is connected to a workpiece locator, the workpiece locator comprises a locating core bar capable of rotating, the shape, size of the locating core bar are matched with the cavity shape of the workpiece, the locating core bar can rotate along the centre line of the dual-V clamping opening along the circumference direction. While processing the workpiece different in diameter, the height is not adjusted and the centre height of the workpiece is constant, the work efficiency and the processing precision can be improved.

Description

technical field [0001] The invention belongs to the technical field of machining, and relates to a keyway milling fixture. Background technique [0002] Keyway milling is a process of milling a keyway on the surface of a workpiece with a milling cutter. The workpiece needs to be clamped and milled with a milling cutter. During the processing, the accuracy of the keyway is required to be high. When clamping the keyways of workpieces with different diameters, if ordinary flat pliers are used, the symmetry between the keyway and the diameter of the workpiece needs to be readjusted, and the center height of workpieces with different diameters clamped by ordinary flat pliers will change, so the end face cavity The height of the alignment device needs to be readjusted, which is time-consuming and laborious and affects the machining accuracy. [0003] In order to overcome the deficiencies of the prior art, various solutions have been proposed through continuous exploration. For ex...
