[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 2 This utility model provides an embodiment of a milling machine positioning mechanism with a quick clamping function, including a base 1. The base 1 serves as the basic support for the entire mechanism, providing a stable platform for the subsequent installation and operation of various mechanisms. The base 1 is equipped with a positioning mechanism for positioning, which can accurately determine the position of the workpiece to be processed during the milling process, ensuring the accuracy of the processing. The positioning mechanism is equipped with a disassembly and assembly mechanism for disassembly and assembly, which can realize the quick disassembly and assembly of clamping components to adapt to the clamping requirements of components of different shapes and sizes. The base 1 is also equipped with a drive mechanism for driving, which provides power for the entire positioning and clamping process, ensuring that each component moves in a predetermined manner. The disassembly and assembly mechanism is equipped with a control mechanism for control, which allows the operator to flexibly control the disassembly and assembly process, improving the convenience of operation.

[0034] The positioning mechanism includes a rotating shaft 2, which serves as the central axis for the rotation of the rotating rod 3. It is securely rotatably connected inside the base 1, providing a rotational basis for the movement of the positioning mechanism. The rotating rod 3 is fixedly connected to the outside of the rotating shaft 2. Under the action of the driving mechanism, the rotating rod 3 rotates around the rotating shaft 2, thereby driving the movement of subsequent components. Transmission rods 4 are rotatably connected to both sides of the rotating rod 3. Sliding blocks 5 are rotatably connected to the opposite sides of the two transmission rods 4. The transmission rods 4 convert the rotation of the rotating rod 3 into linear motion to push the sliding blocks 5 to move. Under the drive of the transmission rods 4, the sliding blocks 5 can slide along a specific path at the top of the base 1.

[0035] Both sliding blocks 5 have fixed blocks 6 fixedly connected to their top ends. The fixed blocks 6 move together with the sliding blocks 5, providing a carrier for the installation and movement of the clamping blocks 10. Fixed rods 9 are slidably connected inside both fixed blocks 6, allowing for flexible sliding within the fixed blocks 6 and enabling detachable connection of the clamping blocks 10. Clamping blocks 10 are fixedly connected to adjacent sides of the two fixed rods 9. The clamping blocks 10 are used to directly clamp the workpiece to be processed, ensuring stable positioning of the workpiece during processing. A second sliding groove 20 is provided at the top of the base 1. The second sliding groove 20 provides a precise sliding track for the sliding blocks 5, ensuring accurate movement of the sliding blocks 5. The external sliding connection of the sliding blocks 5 is slidably connected inside the second sliding groove 20, making the entire positioning process more stable and reliable.

[0036] The drive mechanism includes a cylinder 8, which serves as the core power source of the drive mechanism and is securely fixed inside the base 1. A control rod 7 is fixedly connected to the drive end of the cylinder 8. The cylinder 8 provides power for the movement of the positioning mechanism by driving the movement of the control rod 7. The control rod 7 is externally rotatably connected to the outside of one of the transmission rods 4, transmitting the power of the cylinder 8 to the transmission rod 4, thereby driving the entire positioning mechanism to move. A shelf 21 is fixedly connected to the top of the base 1. The shelf 21 is used to place the device to be processed, providing a stable placement surface for the device.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The disassembly and assembly mechanism includes a fixed box 11, which is firmly fixed to the outside of the fixed block 6, providing installation space for subsequent components. A telescopic column 13 is fixedly connected inside the fixed box 11, and a limit block 12 is fixedly connected to the front end of the telescopic column 13. The telescopic column 13 plays a guiding and supporting role, ensuring the smooth movement of the limit block 12. A telescopic spring 14 is sleeved on the outside of the telescopic column 13. The telescopic spring 14 provides elastic restoring force to the limit block 12, realizing automatic limiting of the fixed rod 9. The limit block 12 slides inside the fixed box 11. Through the action of the telescopic spring 14, the limit and release of the fixed rod 9 are realized. The outside of the limit block 12 is slidably connected to the inside of the fixed block 6, cooperating with the fixed block 6 to jointly complete the restriction and release of the fixed rod 9.

[0038] The rear end of the telescopic spring 14 is fixedly connected to the inside of the fixed box 11, providing a fixed support point for the telescopic spring 14. The other end of the telescopic spring 14 is fixedly connected to the rear end of the limiting block 12. The outside of the limiting block 12 is slidably connected to the inside of the fixed box 11, ensuring that the limiting block 12 slides smoothly in the fixed box 11. The control mechanism includes a second rotating shaft 15, which serves as the center of rotation of the second rotating rod 16 and can be flexibly rotatably connected to the outside of the fixed block 6. The outside of the second rotating shaft 15 is fixedly connected to the second rotating rod 16. The operator can start the action of the control mechanism by pulling the second rotating rod 16 and rotating it around the second rotating shaft 15.

[0039] Both sides of the rotating rod 16 are rotatably connected to the transmission rod 17. The transmission rod 17 converts the rotation of the rotating rod 16 into the linear motion of the control rod 18. The control rod 18 is rotatably connected to the outside of the two transmission rods 17. Driven by the transmission rods 17, the control rod 18 slides in the sliding groove 19 to control the limit block 12. The rear end of the control rod 18 is fixedly connected to the outside of the limit block 12 and acts directly on the limit block 12 to control its position. The fixed box 11 has a sliding groove 19 on its outside. The sliding groove 19 provides a precise sliding track for the control rod 18 to ensure the accurate movement of the control rod 18. The outside of the control rod 18 is slidably connected to the inside of the sliding groove 19, making the operation of the control mechanism more stable and reliable.

[0040] Working principle: When the operator needs to position the part for milling, the part is placed on the top of the placement plate 21. At this time, by activating the cylinder 8, the cylinder 8 drives the control rod 7 to move, which causes the rotating rod 3 to rotate around the rotating shaft 2. This causes the two transmission rods 4 to move in opposite directions, which in turn causes the sliding block 5 to drive the fixed block 6 to slide on the top of the base 1. Finally, the two fixed rods 9 drive the two clamping blocks 10 to clamp and position the part in opposite directions, ensuring that the part is fixed in position during processing. This improves the processing quality and can quickly adapt to parts of different sizes, reducing the preparation time and improving the processing efficiency.

[0041] When dealing with different components, the positioning effect may be reduced due to significant differences in their shapes. In this case, the rotation rod 16 can be pulled to rotate around the rotation shaft 15, causing the transmission rod 17 to drive the control rod 18 to slide inside the sliding groove 19. This allows the limit block 12 to slide inside the fixed box 11, thereby removing the restriction on the fixed rod 9. The fixed rod 9 can then be manually slid out of the fixed block 6 for disassembly and cleaning. When replacing the new clamping block 10, the fixed rod 9 at the rear end of the new clamping block 10 is slid downwards along the opening of the fixed block 6, causing the fixed rod 9 to push the limit block 12 into the fixed box 11. When the fixed rod 9 is fully slid into the bottom of the fixed block 6, the telescopic spring 14 will push the limit block 12 out of the fixed box 11, thus restricting the fixed block 6 and enabling the installation of the clamping block 10. The quick disassembly and assembly structure and simple operation steps reduce preparation time and improve processing efficiency.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
