Description

Technical Field

[0001] The utility model belongs to the technical field of milling machine finishing fixtures, in particular to a milling machine finishing fixture. Background Art

[0002] Milling machine is a widely used machine tool. It can process planes (horizontal and vertical surfaces), grooves (keyways, T-slots, dovetail grooves, etc.), toothed parts (gears, spline shafts, sprockets), spiral surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used for processing the surface of rotating bodies, internal holes and cutting. When the milling machine is working, the workpiece is mounted on the workbench or on accessories such as the indexing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or the milling head, and the workpiece can obtain the required processing surface. Due to the multi-blade intermittent cutting, the productivity of the milling machine is relatively high. Simply put, the milling machine is a machine tool that can perform milling, drilling and boring on the workpiece.

[0003] The above-mentioned device does not have a structure for adjusting the clamping angle of the fixed workpiece when in use, so that most of the existing milling machine fixtures can only perform ordinary clamping and fixing of the workpiece when in use. It is impossible to quickly rotate and adjust a certain angle to turn and mill the other side or other sides after the single-sided milling is completed. The fixation must be released first, and then the position angle of the workpiece must be adjusted and fixed before the operation can continue. It is relatively cumbersome and has poor precision and is inconvenient to use. Based on the deficiencies in the existing technology, the utility model designs a milling machine finishing fixture.
