Embodiment Construction

[0010] Fixtures such as figure 2 As shown, including fixture body 1, side wall 2, positioning ring 3 is installed on side wall 2 through bolts, and positioning V-shaped block 4 is installed on the fixture body to ensure that the middle plane of the V-shaped block is perpendicular to the upper surface of the fixture body, and the sliding positioning The pin 5 is installed on the fixture body 1. By inserting the sliding positioning pin 5 into the end face hole of the workpiece, the workpiece is restricted from rotating around the axis on the V-shaped block. The tool setting block 6 is fixedly connected to the fixture body 1 through the fixing block 7, and is pressed tightly. The block 8 is connected with the support 11 through the screw 9 and the straight groove screw 10, and the handle 12 can be turned to pass the support 11, the straight groove screw 10, the screw 9, and the pressing block 8 to apply clamping force to the parts, and adjust the screw 9 The distance between the...

Abstract

The invention relates to a clamp device dedicated to the machining of the internal cavity of a component with a T-shaped head. The clamp device is simple in structure, and a workpiece is convenient to clamp. The clamp device comprises a base; a U-shaped opening is formed in a slide wall, so that space is reserved for the feed and movement of a tool when the component is machined on a horizontal milling machine; a positioning ring is arranged on the side wall and is fit with the end surface of the workpiece to limit the axial freedom degree of the component; a V-shaped positioning block and a sliding positioning pin are mounted on the base; the radial freedom degree of the component is limited by the V-shaped positioning block and the sliding positioning pin together; a feeler block is mounted on the base of a clamp through a fixed block; the clamp adopts a straight slot screw clamping manner, so that the clamping of the workpiece is facilitated; the work efficiency is improved. Two positioning keys are mounted on the base of the clamp and are matched with the slots of a worktable of the milling machine so as to ensure that the axis of the workpiece is parallel to the axis of the tool.

Description

technical field [0001] The invention relates to a fixture device for processing the inner cavity of a T-shaped head part, in particular to a fixture applied on a horizontal milling machine. Background technique [0002] The material of the T-shaped head part processed by this fixture device is YL12. The part is installed on one axis. The internal cavity is used to install the shift fork to control the small rotation of the part around the axis. The accuracy of the cavity width is high, and The side wall of the cavity is required to be at right angles to the end face. [0003] In modern machining, for the internal cavity of the rotary part, especially the processing that requires no rounded corners between the side wall of the cavity and other surfaces, a three-sided milling cutter is often used for processing on a horizontal milling machine, and the clamping method generally adopts V Shaped blocks, pressure plates, and bolts are clamped, and the labor intensity of workers i...
