Milling machine fixture

Abstract

The invention discloses a milling machine fixture. The milling machine fixture comprises a bottom plate, a first V-shaped block, a second V-shaped block, at least one screw rod group, an upper sliding block and a lower sliding block, the first V-shaped block is arranged at the left side of the bottom plate while the second V-shaped block is arranged at the right side of the bottom plate, both the first V-shaped block and the second V-shaped block are L-shaped iron blocks, and a V-shaped slot is formed in the head face of each of the first V-shaped block and the second V-shaped block; the screw rod group is fixed on the bottom plate and comprises two screw rods engaged to each other through gears, both the upper sliding block and the lower sliding block are arranged on the screw rods, and the screw rods pass through the upper sliding block and the lower sliding block; a rotating handle is arranged at the lower end of one screw rod to drive the screw rod to rotate. The milling machine fixture has high locating precision, the clamping force of the fixture is proper, and moreover, the fixture has enough rigidity and stability so that the regulation is facilitated.

Description

technical field [0001] The invention relates to a clamp device, more specifically, to a movable clamping force adjustable clamp for a milling machine. Background technique [0002] In the technology of machining parts with machine tools, it is generally necessary to fix the parts that need to be processed by fixtures. First of all, it is necessary to determine the relative position of the workpiece and the tool on the machine tool, and then the fixture exerts force on the workpiece to clamp the workpiece. The whole process from workpiece positioning to workpiece clamping is clamping. The main function of the milling machine fixture is to complete the clamping and fixing of the workpiece, and the quality of the clamping of the workpiece directly affects the machining accuracy of the workpiece. [0003] However, the current fixtures have the following problems in the actual machining process of the machine tool: the clamping force of the fixture is not suitable, some clamping...

AI Technical Summary

Problems solved by technology

[0003] However, the current fixtures have the following problems in the actual machining process of the machine tool: the clamping force of the fixture is not suitable, some clamping force is too small, the workpiece moves during the processing and the fixture positioning fails, which not only affects the quality, but also can cause Processing accidents; the clamping force of some fixtures is too large, which will not only deform the workpiece and the fixture itself, but also the processing quality is not high
