Description

Technical Field

[0001] The utility model relates to the technical field of machine tool slide rail accessories, in particular to a machine tool slide rail accessory with a locking function. Background Art

[0002] Guideway pairs, often referred to as guideways or slideways, are parts that support and guide moving components to move along a certain trajectory. The motion trajectory of moving components can be straight, circular or curved. Rolling circular guideways can be classified as rolling thrust bearings, and curved guideways are rarely used in machinery. Guideways are a very important component in machines, especially in machine tools. The machining accuracy of machine tools is directly related to the accuracy of guideways. Although there are many types of existing machine tools, they can be applied to the production needs of various products. However, the guideways on machine tools are generally fixed and may only be applicable to the production of one product during use. They have great limitations. If the same machine tool is used to produce products of different models, the path length of the operating robot arm of the CNC machine tool will change due to different product sizes, which is easy to waste more energy and increase the wear of the operating robot arm, thereby extending the time used for production and reducing production efficiency.

[0003] For example, the publication number CN202221481377.X discloses "A lockable machine tool slide rail accessory". When using it, first loosen the tightening bolt, then move the guide rail body back and forth to the appropriate position as needed, and determine the position by observing the pointer and scale line. Finally, tighten the tightening bolt into the socket at the corresponding position to lock the slide rail, thereby realizing the movement and locking of the slide rail. The position of the slide rail can be adjusted, so that the machine tool can be suitable for producing more products of different sizes, reducing the displacement path of the operating robot arm, reducing the wear of the machine, and reducing the production time, which is beneficial to extending the service life of the machine and improving the production efficiency of the machine tool. Then, the moving parts of the machine tool are assembled on the guide rail body, and the power of the machine tool is turned on to carry out normal production operations.

[0004] However, the intermittent locking and adjustment of the guide rail is still relatively troublesome. The bolts are prone to rust due to long-term use. When rust remains in the socket, it will make it difficult to fix the bolts to the socket, making it impossible to easily adjust the guide rail, thereby indirectly reducing production efficiency.
