[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-4 The utility model provides a machine tool fixture indexing mechanism, including a clamp body 1, a rotating shaft 2 is rotatably installed on the top of the clamp body 1, a drill sleeve 3 is arranged on the right side of the rotating shaft 2 on the clamp body 1, and an indexing mechanism 4 is installed on the bottom end of the clamp body 1 and is arranged on the clamp body 1.

[0024] The indexing mechanism 4 includes an indexing plate assembly 41 and a power assembly 42 . The indexing plate assembly 41 is disposed on the clamp body 1 through the rotating shaft 2 , and the power assembly 42 is disposed under the indexing plate assembly 41 for easy installation on the clamp body 1 .

[0025] The setting of the indexing mechanism 4 ensures that the workpiece can be indexed stably, which facilitates its processing and improves its processing efficiency.

[0026] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the dividing plate assembly 41 includes a plate body 411, the top of the plate body 411 is connected to the rotating shaft 2, and a dividing groove 412 is opened at the bottom of the plate body 411. There are six dividing grooves 412 and they are evenly arranged at the bottom of the plate body 411. Hexagonal grooves are arranged between the six dividing grooves 412 and are connected through them. The dividing grooves 412 are matched with the power assembly 42.

[0027] Further Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the power assembly 42 includes a motor 421, the motor 421 is fixedly installed at the bottom of the clamp body 1, the top of the motor 421 is fixedly connected to a fixed shaft 422, the top of the fixed shaft 422 is fixedly connected to a cam 423, the top of the cam 423 is fixedly connected to a fixed block 424, the top of the fixed block 424 is fixedly connected to a limiting rod 425 near the top of the outer end of the cam 423, a movable plate 426 is arranged on the left side of the cam 423, a sliding rod 427 is penetrated and slidably arranged on the movable plate 426, a spring 4210 is sleeved on the outer side of the sliding rod 427 on the left side of the movable plate 426, and the left side of the movable plate 426 is near the top The top of the disk body 411 is fixedly connected to a connecting block 428, and a baffle 429 is fixedly connected to the side of the top of the connecting block 428 away from the movable plate 426. Two sliding rods 427 are arranged front and back on the movable plate 426 and fixedly connected to the clamp body 1. The axis of the fixed shaft 422 is located on the edge line of the hexagonal groove at the bottom of the disk body 411. The limit rod 425 is matched with the dividing groove 412 through the fixed block 424 and is arranged in the dividing groove 412. The protrusion of the cam 423 is matched with the fixed block 424. The baffle 429 is matched with the protrusion of the cam 423 through the connecting block 428 and is arranged in the dividing groove 412.

[0028] Through the operation of the motor 421, the fixed shaft 422 drives the cam 423 and the fixed block 424 to rotate synchronously, so that the limit rod 425 drives the disk body 411 to rotate on the rotating shaft 2, and then the workpiece rotates to achieve indexing processing and ensure its stability.

[0029] According to the above working process, it can be known that: through the setting of the indexing mechanism 4, the precise indexing work of the indexing disk assembly 41 can be achieved, and the operation of the power assembly 42 can be coordinated to improve the stability of its working process, thereby improving the processing efficiency of the device.

[0030] This scheme has the following working process: when this device is used, the workpiece is installed on the upper part of the disk body 411 through the clamp body 1, and the workpiece can be processed through the drill sleeve 3. At this time, through the operation of the motor 421, the fixed shaft 422 drives the cam 423 and the fixed block 424 to rotate synchronously, so that the limit rod 425 drives the disk body 411 to rotate on the rotating shaft 2, and then the workpiece rotates. When the cam 423 rotates, the protruding part of the cam 423 will squeeze the movable plate 426, so that the movable plate 426 slides on the sliding rod 427 and squeezes the spring 4210, and at the same time, the connecting block 428 drives the blocking rod 429 to move to the left. Under the rotation of the disk body 411, When the limit rod 425 rotates, when the limit rod 425 rotates out of the first dividing groove 412, the cam 423 squeezes the movable plate 426 so that the blocking rod 429 just moves to another dividing groove 412, forming a limiting effect on the disk body 411 to ensure its stability. When the motor 421 continues to run, the limit rod 425 rotates to the next dividing groove 412. At this time, the protruding part of the cam 423 no longer squeezes the movable plate 426, and the movable plate 426 is pushed to reset under the elastic force of the spring 4210, and at the same time, the blocking rod 429 is disengaged from the dividing groove 412, so as to realize the rotation of the disk body 411, thereby realizing the indexing work, and then facilitating the indexing processing of the workpiece.

[0031] In summary: through the setting of the dividing mechanism 4, the precise dividing work of the dividing disk assembly 41 can be realized, and the operation of the power assembly 42 can be improved to improve the stability of its working process, thereby improving the processing efficiency of the device; through the setting of the dividing mechanism 4, the setting structure of its power assembly 42 is relatively simple, which is easy to implement, improves the feasibility, and thus reduces the cost of its production and processing.
