It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Reference Figures 1-7 A machining positioning device includes a base plate 1, a support plate 2 fixedly connected to the upper surface of the base plate 1, a motor 3 fixedly connected to the outer wall of the support plate 2, the support plate 2 being fixed to the upper surface of the base plate 1 to support and fix the motor 3, a transmission shaft 4 fixedly installed at the output end of the motor 3, both ends of the transmission shaft 4 being rotatably connected to the inside of the support plate 2, a cam 5 fixedly connected to the outer wall of the transmission shaft 4, a sliding column 6 slidably connected to the inner wall of the cam 5, a fixing column 7 fixedly connected to the top of the sliding column 6, a turntable 8 fixedly connected to the outer wall of the fixing column 7, one end of a support column 9 fixedly connected to the bottom of the turntable 8, the other end of the support column 9 being rotatably connected to the inside of the base plate 1, the support column 9 fixing the turntable 8, and a drive assembly 10 provided on the upper surface of the turntable 8.

[0033] The process of using the machining positioning device provided by this utility model is as follows:

[0034] When different positions of the workpiece need to be processed, the motor 3 is started. The driving action of the motor 3 causes the transmission shaft 4 to rotate inside the support plate 2. The transmission shaft 4 fixes the cam 5. The transmission action of the transmission shaft 4 drives the cam 5 to rotate synchronously. The inner wall of the cam 5 has a groove that can engage with the sliding column 6. When the cam 5 rotates, the sliding column 6 will slide against its inner wall, and there are always two sliding columns 6 in contact with the cam 5. The rotation of the cam 5 will cause one of the sliding columns 6 to slide out of the cam 5, and during the rotation, the next sliding column 6 will slide to the inner wall of the cam 5. Press the stop button. The rotation cycle of pause-indexing-stop creates intermittent rotation. The sliding column 6 and the turntable 8 fix the fixed column 7, causing the turntable 8 to rotate synchronously with the rotation of the fixed column 7. This rotation drives the fixed box 1001 on the upper surface to rotate, which in turn drives the workpiece to rotate synchronously. When the turntable 8 rotates, it drives the support column 9 to rotate synchronously. The support column 9, located inside the base plate 1, provides stable support for the rotation of the turntable 8. The intermittent rotation of the turntable 8 drives the workpiece to rotate intermittently, ensuring that the workpiece is precisely aligned at each processing position and improving processing accuracy.

[0035] Reference Figure 6 and Figure 7 The drive assembly 10 includes a fixed box 1001. The lower surface of the fixed box 1001 is fixedly connected to the upper surface of the turntable 8. The turntable 8 supports and fixes the fixed box 1001. An electric push rod 1002 is fixedly connected inside the fixed box 1001.

[0036] The process of using the machining positioning device provided by this utility model is as follows:

[0037] When the turntable 8 rotates, it will drive the fixed box 1001 on the upper surface to rotate as well. When the workpiece is fixed on the fixed box 1001, it can drive the workpiece to rotate and process different positions of the workpiece to ensure the consistency of the processing position. The fixed box 1001 plays a supporting and fixing role for the electric push rod 1002, and the electric push rod 1002 can provide driving force.

[0038] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7The output end of the electric push rod 1002 is fixedly connected to a push block 11. A connecting block 12 is fixedly connected to the upper surface of the push block 11, which supports and fixes the connecting block 12. A fixing plate 13 is slidably connected to the outer wall of the connecting block 12. The outer wall of the fixing plate 13 is fixedly connected to the inside of the fixing box 1001, and the fixing plate 13, fixed inside the fixing box 1001, supports and limits the connecting block 12. A first connecting shaft 14 is fixedly connected to the upper surface of the connecting block 12. One end of a first rotating plate 15 is rotatably connected to the outer wall of the first connecting shaft 14, which connects the first rotating plate 15 and the connecting block 12. A second connecting shaft 16 is fixedly connected to the other end of the first rotating plate 15, and a limit block 21 is rotatably connected to the outer wall of the second connecting shaft 16. A third connecting shaft 17 is fixedly connected to the inside of the first rotating plate 15, and a second rotating plate 18 is rotatably connected to the outer wall of the third connecting shaft 17. One end of the second rotating plate 18 is rotatably connected to the first fixed shaft 19, and the other end of the second rotating plate 18 is fixedly connected to the second fixed shaft 20. The outer wall of the second fixed shaft 20 is rotatably connected to the inside of the limiting block 21. The second fixed shaft 20 serves to connect the second rotating plate 18 and the limiting block 21. The outer wall of the limiting block 21 is slidably connected to the support block 22. The upper surface of the support block 22 is fixedly connected to the slider 23. The outer wall of the slider 23 is slidably connected to the inner wall of the fixed box 1001. The upper surface of the slider 23 is fixedly connected to the first clamping plate 24. The slider 23 serves to connect the support block 22 and the first clamping plate 24. The inside of the first clamping plate 24 is slidably connected to the limiting post 25. The outer wall of the limiting post 25 is fixedly connected to the second clamping plate 26. The outer wall of the limiting post 25 is slidably connected to the spring 27. One end of the spring 27 is fixedly connected to the outer wall of the second clamping plate 26, and the other end of the spring 27 is fixedly connected to the outer wall of the first clamping plate 24.

[0039] The process of using the machining positioning device provided by this utility model is as follows:

[0040] When it is necessary to fix the workpiece, the workpiece to be processed is placed on the upper surface of the fixing box 1001. The electric push rod 1002 is activated, which pushes the push block 11 to slide. When the push block 11 slides, it will drive the connecting block 12 on the upper surface to slide as well. The connecting block 12 is set on the inner wall of the fixing plate 13. The connecting block 12 will slide against the inner wall of the fixing plate 13, limiting its own movement trajectory and preventing deviation during the sliding process. The connecting block 12 plays a role in fixing the first connecting shaft 14, while the first rotating plate 15 plays a role in supporting the first connecting shaft 14, so that the first rotating plate 15 can rotate synchronously through the sliding of the first connecting shaft 14. The third connecting shaft 17 connects the first rotating plate 14. The function of the second rotating plate 18 is to cause the second rotating plate 18 to rotate synchronously through the rotation of the third connecting shaft 17. One end of the first rotating plate 15 is connected to the first connecting shaft 14, and the other end is connected to the second connecting shaft 16. The second connecting shaft 16 rotates inside the limiting block 21, so that the limiting block 21 can slide synchronously through the sliding of the second connecting shaft 16, setting the limiting block 21 inside the support block 22. The limiting block 21 will slide against the inner wall of the support block 22, thereby limiting and supporting the rotation of the first rotating plate 15. Similarly, the limiting block 21 on the other side of the support block 22 will also slide due to the second fixed shaft 20, limiting and supporting the rotation of the second rotating plate 18. The sliding of the support block 22 will drive the sliding... Block 23 slides synchronously, and slider 23 slides against the inner wall of the fixed box 1001 to prevent deviation during sliding. Slider 23 fixes the first clamping plate 24 and can drive the first clamping plate 24 to slide synchronously. Limiting post 25 connects the first clamping plate 24 and the second clamping plate 26. The second clamping plate 26 slides with the first clamping plate 24. When the second clamping plate 26 contacts the workpiece, the workpiece will exert a compressive force on the second clamping plate 26, causing it to push the limiting post 25 to slide inside the first clamping plate 24. Spring 27 is set between the first clamping plate 24 and the second clamping plate 26. Spring 27 will be compressed due to the sliding of the second clamping plate 26. Spring 27 plays a buffering and protective role to avoid over-clamping of the workpiece. To prevent damage to the workpiece surface, the other ends of the first rotating plate 15 and the second rotating plate 18 are respectively connected to the first connecting shaft 14 and the first fixed shaft 19. Through the first connecting shaft 14 and the first fixed shaft 19, a connection can be established with the first rotating plate 15 and the second rotating plate 18 on the other side, so that the first rotating plate 15 and the second rotating plate 18 on one side rotate synchronously through the rotation of the first rotating plate 15 and the second rotating plate 18 on the other side, thereby driving the second clamping plate 26 on the other side to slide. Through the sliding of the second clamping plates 26 on both sides, the workpiece can be clamped and fixed. The second clamping plate 26, which is easy to adjust in position, can adapt to workpieces of different sizes, ensuring that workpieces of different sizes can be firmly clamped, while avoiding over-clamping and preventing damage to the workpiece surface.

[0041] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0042] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.
