[0002] A code disc refers to a digital encoder that measures angular displacement. It has the advantages of strong resolution, high measurement accuracy, and reliable operation. It is the most commonly used displacement sensor for measuring shaft angular position. Code discs are divided into two types: absolute encoders and incremental encoders. The former can directly give a digital code corresponding to the angular position, while the latter uses a computing system to add or subtract the pulse increments generated by the rotating code disc relative to a certain reference number. In the manufacturing process of code discs, laser processing technology is widely used. During the laser processing process, the fixation of the code disc has a crucial impact on the processing accuracy and quality. Therefore, a vacuum adsorption fixture for code disc laser processing is particularly needed.

The fixed fixture may not be accurately fixed in the optimal position. The fixed fixture position will limit the processing angle and range and cannot meet diverse processing needs.

[0022] The sliding mechanism 7 includes a sliding groove 701, a limiting groove 702, a limiting block 703, a sliding block 704, a first moving groove 705, a spring 706, a first clamping block 707, a connecting rod 708, a limiting groove 709, a second clamping block 710, a positioning block 711 and a positioning groove 712.

[0023] Furthermore, two groups of limit blocks 703 are symmetrically arranged around the central axis of the sliding block 704.

[0025] Furthermore, the outer dimensions of the positioning block 711 are consistent with the inner dimensions of the positioning groove 712, and multiple groups of positioning grooves 712 are arranged at equal intervals on the inner surface of the sliding groove 701. Through the arrangement of the positioning grooves 712, when in use, multiple groups of equally spaced positioning grooves 712 provide the sliding block 704 with multiple optional positioning positions, greatly increasing the flexibility and adaptability of the clamping mechanism 8.
[0026] Furthermore, the clamping mechanism 8 includes a fixed block 801, a fixed plate 802, a first rotating groove 803, a first rotating shaft 804, a connecting block 805, a second rotating groove 806, a third rotating groove 807, a second rotating shaft 808, a pressing plate 809, a handle 810, a fourth rotating groove 811, a fifth rotating groove 812, a third rotating shaft 813, a connecting plate 814, a sixth rotating groove 815, a seventh rotating groove 816, a fourth rotating shaft 817, an eighth rotating groove 818, a threaded hole 819, a threaded column 820, a pressing block 821 and a nut 822. The upper surface of the sliding block 704 is fixedly connected to the fixed block 801, the fixed block 801, and the upper surface of the fixed block 801 is fixedly connected to the fixed plate 802. The inner surface of the first rotating groove 803 is provided with a first rotating shaft 804, and the outer surface of the first rotating shaft 804 is rotatably connected to the connecting block 805. The inner surface of the connecting block 805 is provided with a second rotating groove 806, and the inner surface of the connecting block 805 is provided with a third rotating groove 807. The inner surface of the third rotating groove 807 is rotatably connected to the second rotating shaft 808.

The inner surface of the pressing plate 809 is provided with a fourth rotating groove 811. The inner surface of the pressing plate 809 is provided with a fifth rotating groove 812.

When in use, the entire clamping mechanism 8 is connected to the sliding block 704 through the fixed block 801. The fixed block 801 provides a stable support base for the upper fixed plate 802 and other components. The first rotating groove 803 on the fixed plate 802 is rotatably connected to the first rotating shaft 804.The first rotating shaft 804 is connected to the connecting block 805. This rotating connection mode enables the connecting block 805 to rotate flexibly relative to the fixed plate 802. The second rotating groove 806 and the third rotating groove 807 of the connecting block 805 are connected to the clamping plate 809 through the second rotating shaft 808, giving the clamping plate 809 the ability to rotate within a certain range. When the operator holds the handle 810, an external force is applied. The handle 810 is fixed on the clamping plate 809. The external force is transmitted to the clamping plate 809 through the handle 810. Since the clamping plate 809 is connected to the connecting block 805 through the second rotating shaft 808, the clamping plate 809 starts to rotate around the second rotating shaft 808, which changes the angle of the clamping plate 809 and gradually approaches the stabilizing plate 5 that needs to be clamped. When the clamping plate 809 rotates, the fourth rotating groove 811, the fifth rotating groove 812 on its inner surface and the third rotating shaft 813 and the connecting plate 8 The rotational connections between the sixth rotation groove 815, the seventh rotation groove 816, the fourth rotation shaft 817 and the eighth rotation groove 818 of the fixed plate 802 work together. These rotational connections enable the connecting plate 814 to rotate accordingly with the rotation of the clamping plate 809, ensuring that the entire mechanism can adapt to the shape of the stabilizing plate 5 during the clamping process, and can automatically adjust the angle and position to adapt to different workpieces, thereby achieving a tighter and more stable clamping effect. The threaded hole 819 on the connecting plate 814 is threadedly connected to the threaded column 820, and one end of the threaded column 820 is connected to the clamping block 821. By rotating the threaded column 820, the clamping block 821 can be moved closer to or away from the stabilizing plate 5, thereby adjusting the size of the clamping force. The clamping force can be accurately controlled according to factors such as the thickness and material of the different code discs 4 and the stabilizing plate 5, ensuring that the code disc 4 is firmly fixed during the processing and will not be damaged by excessive extrusion.
[0027] Furthermore, the second rotating groove 806 is rotationally connected to the first rotating shaft 804, the second rotating shaft 808 is rotationally connected to the fourth rotating groove 811, the third rotating shaft 813 is rotationally connected to the sixth rotating groove 815, and the fourth rotating shaft 817 is rotationally connected to the eighth rotating groove 818, so that the connecting block 805 can be flexibly rotated around the first rotating shaft 804 in the second rotating groove 806. Through the setting of the second rotating groove 806, the first rotating shaft 804, the second rotating shaft 808, the fourth rotating groove 811, the third rotating shaft 813, the sixth rotating groove 815, the fourth rotating shaft 817 and the eighth rotating groove 818, when in use, the various components cooperate with each other, so that the clamping mechanism 8 can effectively complete the task when facing different clamping requirements, ensuring that the code disk 4 can be firmly fixed during the processing process, thereby ensuring the processing accuracy.
[0028] Furthermore, two groups of fixing plates 802 are provided, and two groups of nuts 822 are provided. Through the setting of the fixing plates 802, when in use, the two groups of fixing plates 802 are symmetrically arranged, providing a more stable support structure for the entire clamping process, further improving the stability and reliability of the clamping.
[0029] Working principle: the code disc 4 is placed on the placement block 2, the placement block 2 is located on the inner side of the base 1 and has adsorption holes 3 on its surface. When the external vacuum equipment is working, the adsorption holes 3 generate suction to tightly adsorb the code disc 4 on the placement block 2. The shape and size of the code disc groove 6 match the code disc 4, so that the code disc 4 can be accurately located at the center of the stabilizing plate 5 when placed, and the code disc 4 is further positioned and limited. During the processing, the stabilizing plate 5 can prevent the code disc 4 from deviating due to external interference, and also provide a stable clamping surface for the clamping mechanism 8. The entire clamping mechanism 8 is connected to the sliding block 704 through the fixed block 801. The fixed block 801 provides a stable support base for the fixed plate 802 and other components above. The first rotating plate 802 on the fixed plate 802 The movable groove 803 is rotatably connected to the first rotating shaft 804, and the first rotating shaft 804 is connected to the connecting block 805. This rotating connection mode enables the connecting block 805 to rotate flexibly relative to the fixed plate 802. The second rotating groove 806 and the third rotating groove 807 of the connecting block 805 are connected to the clamping plate 809 through the second rotating shaft 808, giving the clamping plate 809 the ability to rotate within a certain range. When the operator holds the handle 810, an external force is applied. The handle 810 is fixed on the clamping plate 809. The external force is transmitted to the clamping plate 809 through the handle 810. Since the clamping plate 809 is connected to the connecting block 805 through the second rotating shaft 808, the clamping plate 809 starts to rotate around the second rotating shaft 808, changing the 9, so that it gradually approaches the stabilizing plate 5 that needs to be clamped. When the clamping plate 809 rotates, the fourth rotating groove 811 and the fifth rotating groove 812 on its inner surface work together with the third rotating shaft 813, the sixth rotating groove 815 and the seventh rotating groove 816 of the connecting plate 814, the fourth rotating shaft 817, and the eighth rotating groove 818 of the fixed plate 802. These rotating connections make the connecting plate 814 rotate accordingly with the rotation of the clamping plate 809, ensuring that the entire mechanism can adapt to the shape of the stabilizing plate 5 during the clamping process, and can automatically adjust the angle and position to adapt to different workpieces, thereby achieving a tighter and more stable clamping effect. The threaded hole 819 on the connecting plate 814 is threaded with the threaded column 820 The screw thread column 820 is connected to the clamping block 821 at one end. By rotating the screw thread column 820, the clamping block 821 can be moved closer to or away from the stabilizing plate 5, thereby adjusting the size of the clamping force. The clamping force can be accurately controlled according to factors such as the thickness and material of the different code discs 4 and the stabilizing plate 5 to ensure that the code disc 4 is firmly fixed during the processing and will not be damaged by excessive extrusion. The sliding groove 701 above the base 1 provides a moving track for the entire sliding mechanism 7, and the limiting groove 702 opened on the inner surface of the sliding groove 701 cooperates with the limiting block 703 to limit the movement of the sliding block 704. When the sliding block 704 is pushed or pulled, the limiting block 703 slides smoothly in the limiting groove 702, thereby driving the entire clamping mechanism 8 to move to the appropriate position.When the sliding block 704 moves, the spring 706 is compressed. When the sliding block 704 moves to the vicinity of the predetermined position, the spring 706 pushes the first clamping block 707, the connecting rod 708 and the second clamping block 710, so that they are clamped into the positioning groove 712 on the inner surface of the sliding groove 701. The sliding mechanism 7 adjusts the position of the clamping mechanism 8 according to the size and processing requirements of different code disks 4 and stabilizing plates 5. In addition, the position stability of the clamping mechanism 8 can be maintained during normal use to avoid changes in the clamping position due to external factors such as vibration, thereby ensuring the clamping effect and processing accuracy of the code disk 4 and stabilizing plate 5.
