[0002] A rotating mechanism refers to a mechanism used to realize the rotation of an object. There are many types of rotating mechanisms, such as plane rotating mechanisms, space rotating mechanisms, tilt rotating mechanisms, etc. The most common of them is the plane rotating mechanism, which is usually composed of bearings, gears, couplings, motors and other components. It is used to realize the horizontal or vertical rotation of objects. At present, rotating mechanisms are widely used in various industrial production equipment and machinery manufacturing, such as machine tools, automated production lines, industrial robots, etc.

[0003] Rotating mechanisms are generally used for processing parts. During the processing, the angles of the parts can be adjusted so that the operator can process the parts at various angles to meet the needs of the workpiece. Existing fixing mechanisms generally rotate with the parts and are subject to the constraints of the lines, resulting in a small rotation angle. In addition, the parts are mostly fixed by extrusion on both sides, which has a poor clamping effect and low stability. Slippage is likely to occur during the processing, which affects the processing accuracy. At the same time, the rotating mechanism needs to be locked during the processing of parts. Based on this, the present invention provides a locking device for a rotating mechanism to solve the above-mentioned problems. Utility Model Content

After the angle adjustment is completed, the fixing mechanism 9 is started to fix the parts for convenience of processing. At the same time, the locking mechanism 10 is started to fix the locking plate 8 so that it no longer rotates, and then the fixed rotating shaft 2 no longer rotates, thereby ensuring that the rotating shaft 2 will not drive the support table 4 to rotate during the processing, thereby ensuring the stability and accuracy of the processing.

[0023] Specifically, in this embodiment, the fixing mechanism 9 includes a fixing plate 901 and a telescopic cylinder 902. The fixing plate 901 is fixedly mounted on the upper end of the mounting platform 1. The telescopic cylinder 902 is fixedly mounted on the outer end of the fixing plate 901. The output end of the telescopic cylinder 902 is fixedly connected to the mounting plate 903. The other end of the mounting plate 903 is fixedly connected to a connecting rod 905. The other end of the connecting rod 905 is rotatably connected to a clamping plate 904. The end of the clamping plate 904 away from the connecting rod 905 is fixedly connected to an anti-slip pad 908. One end of the clamping plate 904 close to the connecting rod 905 is rotatably connected to one end of a pair of telescopic rods 906.

The size of the roller 1007 matches the size of the locking slot 801. Driven by the telescopic cylinder 1002, the movable plate 1003 drives the roller 1007 to approach the locking plate 8, and the locking plate 8 rotates with the rotating shaft 2. By inserting the roller 1007 into the locking groove 801, the locking plate 8 is fixed and no longer rotates, and then the rotating shaft 2 is fixed and no longer rotates, thereby ensuring that the rotating shaft 2 will not drive the support table 4 to rotate during the processing, thereby ensuring the stability and accuracy of the processing.

The surface of the part, combined with the anti-slip pad, has a good clamping effect and high stability, so that the fixing mechanism 9 is not prone to sliding during the process of fixing the part, thereby ensuring the accuracy of processing; at the same time, the locking mechanism is started and driven by the telescopic cylinder 1002, so that the movable plate 1003 drives the roller 1007 to approach the locking plate 8, and the locking plate 8 rotates with the rotating shaft 2, and the roller 1007 is inserted into the locking groove 801, so that the locking plate 8 is fixed and no longer rotates, and then the rotating shaft 2 is fixed and no longer rotates, thereby ensuring that the rotating shaft 2 will not drive the support table 4 to rotate during the processing, thereby ensuring the stability and accuracy of the processing.
