Description

Technical Field

[0001] The utility model relates to the field of keyway milling machine fixtures, in particular to a milling machine fixture which is easy to operate. Background Art

[0002] A milling machine is a machine tool with a wide range of uses. It can process planes, grooves, toothed parts, spiral surfaces 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 clamped on accessories such as fixtures, and the rotation of the milling cutter is the main motion, supplemented by the feed motion of the worktable or milling head, so that the workpiece can obtain the required processing surface. Due to the multi-blade intermittent cutting, the productivity of the milling machine is relatively high. In simple terms, the milling machine is a machine tool that can perform milling, drilling and boring on the workpiece.

[0003] The milling of keyways for shaft parts is mostly performed on milling machines. Before the keyway milling operation, the shaft parts need to be clamped and fixed. At this time, the fixture used to clamp the shaft parts can come in handy. The existing fixtures for shaft parts are relatively cumbersome to clamp, requiring workers to operate the fixture multiple times to complete the clamping of the parts. However, this method is unreliable, causing great hidden dangers to the processing quality of the workpiece, and requires a high level of operator experience. The existing fixtures have poor versatility. Often, one fixture can only be used to clamp one part. Purchasing different fixtures increases the company's expenses and is not conducive to the company's fixture management work. It does not meet the requirements of modern processing for the use of fixtures. Because the workpieces processed by keyway milling machines are generally shafts, which are difficult to fix, in order to ensure the processing accuracy, support devices need to be set on both sides to ensure that the center of the workpiece is consistent with the processing center, and the workpiece needs to be clamped to ensure that the workpiece does not move during processing to improve the processing accuracy. The existing clamping device has a complex structure and is inconvenient to adjust, which is not suitable for keyway milling machines. Therefore, we propose a milling machine fixture that is easy to operate to solve the above problems. Utility Model Content
