Description

Technical Field

[0001] This utility model relates to the field of CNC numerical control technology, specifically a CNC side milling fixture. Background Technology

[0002] CNC machine tools are mechanical devices that use computer numerical control technology. They control the movement and operation of the machine tool through pre-programmed instructions and are used to manufacture various parts and workpieces. CNC machine tools can perform precise and complex tasks, such as cutting, drilling, milling and shaping materials such as metal, wood and plastic. The application of CNC technology automates and streamlines the manufacturing process, improving production efficiency, accuracy and productivity. In CNC side milling, tooling fixtures are usually required to hold the workpiece. However, the position of the fixture is usually fixed during use. Therefore, the adjustment of the angle and position of the workpiece is not effective in side milling, which affects the processing efficiency. Utility Model Content

The outer surface of the bottom end of the threaded rod 9 is fixedly connected to the inner ring of the bearing 10, which better supports the bottom end of the threaded rod 9 and avoids the problem of swaying when the threaded rod 9 rotates.

[0030] Each slider 7 has a mounting bracket 21 fixedly installed on its right side. A fixed plate 14 is placed between two mounting brackets 21. A rotating shaft 15 is fixedly installed at both the front and rear ends of the fixed plate 14. Each mounting bracket 21 has a bearing 22 embedded inside. The outer ends of the two rotating shafts 15 pass through the two bearings 22 and extend to the outside of the mounting bracket 21.
