Abstract

The invention discloses a milling machine fixture. The milling machine fixture comprises a fixing base, a positioning flat key, a rotating hand wheel, a supporting plate, a locking bolt, a bearing bush, a main movable block rotating shaft, a main movable block body, a main movable block push rod, a main movable block positioning element, connecting shafts, auxiliary movable block rotating shafts, auxiliary movable block bodies, auxiliary movable block push rods, auxiliary movable block positioning elements, a pressing disc, a pressing support, a pressing hand wheel, a fixing bolt, a long connecting rod and a short connecting rod. By the adoption of the design, when thin-wall sleeve type parts are positioned, the positioning precision is improved, radial deformation is reduced in the clamping process, the machining precision is improved, the number of the connecting shafts and the number of auxiliary movable blocks can be flexibly selected, and the milling machine fixture can be suitable for the thin-wall sleeve type parts with different length sizes.

Description

technical field

[0001] The invention relates to the technical field of machining, in particular to a milling machine fixture. Background technique

[0002] A milling machine is a machine tool that mills a workpiece with a milling cutter with multiple teeth. It can be used to process plane, curved surface, groove and rotary parts. During milling machine processing, the workpiece is installed and fixed on the fixture of the milling machine, the main motion of the milling machine is the rotation of the milling cutter, and the feed motion of the milling machine is the movement of the workpiece. The commonly used fixtures for milling machines include flat-nose pliers, pressure plates, dividing heads, and three-jaw chucks. When these fixtures clamp thin-walled sleeve parts, they are likely to cause radial deformation of the workpiece and affect machining accuracy. Therefore, a milling machine fixture is designed to solve the above problems. Contents of the invention
