Embodiment Construction

[0033] The present invention is described in detail below in conjunction with accompanying drawing:

[0034] like Figure 1-3 As shown, the present invention provides a general-purpose turning fixture for rear axle shaft parts, including a base 1, a spring 2, a spring slider 3, a spring baffle 4, a clamp body 5, an expansion sleeve 6, a left top 7, and a right top 10, dovetail slider 8, clamping block 11. It is characterized in that: the base 1 is arranged on the main shaft head, and is fixed by locking bolts through the taper hole and the taper of the main shaft head. The base 1 is provided with a blind hole, the spring 2 and the spring slider 3 are placed in the hole, and the spring baffle 4 is connected and fixed with the base 1 through locking bolts, so as to limit the movement stroke of the spring 2 and the spring slider 3 in the base 1. The clip body 5 is connected and fixed with the spring baffle 4 through locking bolts. The expansion sleeve 6 is placed in the clamp ...

Abstract

The invention belongs to the technical field of mechanical manufacturing, and relates to a universal turning fixture for rear axle gear shaft parts. Including the base, spring, spring slider, spring baffle, clamp body, expansion sleeve, left top, right top, dovetail slider and clamping block; the base has a blind hole, the spring and the spring slider are placed in the blind hole, and the spring The baffle is connected and fixed with the base through the locking bolt, and the clamp body is connected and fixed with the spring baffle through the locking bolt; the expansion sleeve is placed in the clamp body, and the internal thread of the left top is connected with the external thread on the spring slider to make the expansion sleeve Fixed on the spring slider, the expansion sleeve and the left top can move with the spring slider; the dovetail slider is fixed on the expansion sleeve, and the clamping block is fixed on the dovetail slider; the right top is fixed on the tailstock of the machine tool. The invention can adjust the height according to the diameter of the surface cone of the active bevel gear part to be processed, and adjust the angle of the clamping block according to the angle of the surface cone, and has strong versatility and high working efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a universal turning fixture for rear axle gear shaft parts. Background technique [0002] In the process of processing the active bevel gear parts of the rear axle gear, turning is usually used to ensure the accuracy of the shaft parts. [0003] At present, in the turning process of active bevel gears, there are three commonly used clamping methods: [0004] (1) "One clamp and one top" clamping: First, use a three-jaw self-centering chuck to clamp one end of the part, and then use the top of the tailstock of the machine tool to tighten the other end, and then perform turning processing. This clamping method is not only inefficient, but also Moreover, the parts are prone to deformation during the clamping process, resulting in a decrease in positioning accuracy; [0005] (2) "Two tops" clamping: Use two tops to tighten the parts, and use the heart clip to assist c...
