[0041] A linear slide groove 10 is provided at the top of the load-bearing slide rail 2 and along the length direction of the load-bearing slide rail 2, and an extension plate 11 is fixedly connected to the side of the load-bearing slide rail 2; the connecting slide seat 4 includes a transverse slide plate 7, which is slidably connected to the load-bearing slide rail 2 through a linear slide groove 10, and a limiting guide frame 8 is detachably fixedly connected to the side of the transverse slide plate 7, and the limiting guide frame 8 is slidably connected to the side of the load-bearing slide rail 2, and the limiting guide frame 8 is slidably connected to the lower end of the extension plate 11; the upper end of the limiting guide frame 8 is detachably fixedly connected to a load-bearing connecting frame 9, and the load-bearing connecting frame 9 is detachably fixed to the load-bearing plate group 3.

[0042] Furthermore, the limiting guide frame 8 is arranged in a vertical Z shape, and a connecting bracket 13 is fixedly connected to the upper side of the limiting guide frame 8, and the connecting bracket 13 is horizontally plug-in connected to the horizontal slide 7, and the connecting bracket 13 is detachably fixedly connected to the horizontal slide 7 through a fixing screw 14, and a plurality of moving wheels 12 are rotatably connected to the horizontal slide 7 in a linear distribution, and the horizontal slide 7 is slidably connected to the linear slide groove 10 provided on the bearing slide rail 2 through the moving wheel 12. The installation and disassembly of the limiting guide frame 8 and the horizontal slide 7 can be realized by cooperating with the connecting bracket 13 and the fixing screw 14, so as to facilitate the replacement of the horizontal slide 7 and the limiting guide frame 8.

[0043] Furthermore, a moving wheel 2 15 is laterally rotatably connected to the top inner side of the limiting guide frame 8, and the limiting guide frame 8 is rollingly connected to the side of the supporting slide rail 2 through the moving wheel 2 15. A moving wheel 3 16 is vertically rotatably connected to the bottom inner side of the limiting guide frame 8, and the moving wheel 3 16 is located at the lower end of the extension plate 11. The upper end of the moving wheel 3 16 is rollingly connected to the lower end of the extension plate 11. The movement of the limiting guide frame 8 can be guided and limited by the moving wheels 2 15 and 3 16 to avoid the limiting guide frame 8 from being separated from the supporting slide rail 2.

[0044] Furthermore, the load-bearing connecting frame 9 is arranged in a T shape, and both sides of the upper end of the load-bearing connecting frame 9 are detachably fixedly connected to the load-bearing plate group 3 by fixing screws 3 18, the lower end of the load-bearing connecting frame 9 is fitted with the upper end side of the limiting guide frame 8, the top of the limiting guide frame 8 is fitted with the top of the side of the load-bearing connecting frame 9, and the upper part of the limiting guide frame 8 is detachably connected to the lower end of the load-bearing connecting frame 9 by fixing screws 2 17; the load-bearing plate group 3 is lifted by the load-bearing connecting frame 9, and the connection between the limiting guide frame 8 and the load-bearing connecting frame 9 is achieved by fixing screws 2 17, so that after the fixing screws 2 17 are removed, the limiting guide frame 8 and the load-bearing connecting frame 9 can be disassembled, thereby facilitating the replacement of the limiting guide frame 8 and the load-bearing connecting frame 9.

[0045] It can be seen that, through the connection between the load-bearing connecting frame 9 and the limiting guide frame 8, the pressure of the load-bearing plate group 3 is transmitted to the limiting guide frame 8 through the load-bearing connecting frame 9, and through the connection between the limiting guide frame 8 and the horizontal slide 7, the horizontal slide 7 can realize the downward pressure of the load-bearing connecting frame 9, and the horizontal slide 7 can realize the rolling connection with the load-bearing slide rail 2 through the moving wheel 12, and the movement of the moving wheel 12 can be guided and limited by the linear slide 10; the moving wheel 2 15 set on the top of the inner side of the limiting guide frame 8 and the side of the load-bearing slide rail 2 The rolling connection can guide the limit guide frame 8 in the horizontal direction and avoid the deviation of the limit guide frame 8, thereby effectively reducing the friction generated by the side of the moving wheel 12 and the side of the linear slide groove 10; and through the rolling connection between the moving wheel 3 16 and the bottom of the extension plate 11, the limit guide frame 8 cannot move upward, and the limit guide frame 8 and the bearing slide rail 2 are connected and locked, so that the limit guide frame 8 will not be separated from the bearing slide rail 2, thereby effectively ensuring the connection between the bearing plate group 3 and the bearing slide rail 2.

[0046] A T-shaped slide groove 19 is opened at the top of the load-bearing plate group 3 and along the length direction of the load-bearing plate group 3, and the pulley group 6 is set into two groups, and the two groups of pulley groups 6 are respectively arranged at the positions on both sides of the lower end of the load-bearing plate group 5; the ends of the T-shaped slide groove 19 are provided with limiting members for limiting the movement of the load-bearing plate group 5; specifically, the limiting members include a movable baffle 20, and the movable baffle 20 is arranged in a V shape, and the middle part of the movable baffle 20 is rotatably connected with the load-bearing plate group 3, one end of the movable baffle 20 is located inside the T-shaped slide groove 19, and the other end of the movable baffle 20 is inside the load-bearing plate group 3.

[0047] Furthermore, each group of pulley blocks 6 is arranged in two rows, and each row of pulley blocks 6 is provided with four pulley frames, the two pulley frames at the same end are symmetrically arranged with the two pulley frames at the other end, the pulley frames are located inside the T-shaped slide groove 19, and the load-bearing plate group 5 is slidingly connected with the load-bearing plate group 3 through the cooperation of the pulley frame and the T-shaped slide groove 19; when the four pulley frames in each row of pulley blocks 6 inside the T-shaped slide groove 19, after the pulley frame at the end passes through the limit member, the limit member blocks the remaining three pulley frames.

[0048] It can be known that the sliding connection between the bearing plate group 5 and the bearing plate group 3 is realized by cooperating with the T-shaped slot 19 provided at the upper end of the bearing plate group 3 and the pulley group 6 at the lower end of the bearing plate group 5. The movement of the pulley group 6 can be guided and limited by the T-shaped slot 19, and the movement of the bearing plate group 5 can be limited by the limiting component at the end of the T-shaped slot 19 to avoid the bearing plate group 5 from slipping. The design of two rows of pulley groups 6, with four pulley frames in each row, makes it possible to arrange at least four pulley frames symmetrical in pairs inside each T-shaped slot 19. When the pulley frame moves inside the T-shaped slot 19, when one of the pulley frames at the end of the four pulley frames moves to the position of the movable stop frame 20, the movable stop frame 20 is located in the T-shaped slot 1 through the pulley frame at the end. 9 is squeezed, so that the squeezed end of the movable stop frame 20 moves toward the inside of the load-bearing plate group 3, so that the pulley frame at the end can pass through the movable stop frame 20. At the same time, during the squeezing of one end of the movable stop frame 20, the other end of the movable stop frame 20 moves out from the load-bearing plate group 3 and moves into the inside of the T-shaped slide groove 19, so that the remaining three pulley frames except the end can be blocked, so that they can no longer continue to move toward the end of the T-shaped slide groove 19, thereby achieving the limiting effect; when the four pulley frames move in the opposite direction, the pulley frame at the end squeezes the end of the movable stop frame 20 located in the T-shaped slide groove 19 again, and the pulley frame at the end returns to its original state after passing through the movable stop frame 20, so that the next blocking and limiting can be performed.

[0049] It also includes a driving component, which includes a fixed frame 23, a movable beam 24 is laterally arranged at the upper end of the fixed frame 23, the end of the movable beam 24 is laterally slidably connected to the fixed frame 23 through a first linear motor 25, a movable mounting frame 26 is arranged on the side of the movable beam 24, the movable mounting frame 26 is longitudinally slidably connected to the movable beam 24 through a second linear motor 27, a lifting mechanism 28 is arranged on the side of the movable mounting frame 26, the telescopic end of the lifting mechanism 28 is arranged downward, and a contact pressure frame 29 is detachably arranged at the telescopic end of the lifting mechanism 28, and the contact pressure frame 29 corresponds to the position of the carrier plate group 5.

[0050] It can be seen that after the wooden board or the guzheng box body parts are placed on the upper end of the bearing plate group 5, the contact pressure frame 29 can be pushed to press the wooden board or the guzheng box body parts downward by starting the lifting mechanism 28, thereby cooperating with the bearing plate group 5 to achieve the downward clamping. By starting the first linear motor 25, the movable beam 24 can be driven to move horizontally, and by starting the second linear motor 27, the movable mounting frame 26 can be driven to move longitudinally. During the movement, the bearing plate group 5 can follow the movement through the cooperation of the lower bearing slide rail 2, the bearing plate group 3, and the connecting slide 4, so that workers or cutting and polishing equipment can process the workpiece on the bearing plate group 5 without moving in one position.

[0051] It can be seen that through the structural coordination design of the bearing slide rail 2, the bearing plate group 3, the connecting slide seat 4, the bearing disc group 5, and the pulley group 6, the device can lift the workpiece to move in the horizontal and vertical directions, and can be rotated and adjusted with the bearing disc group 5 as the axis, so that a person can stand in place and hold the processing equipment to cut or polish the workpiece, reducing the increase in work intensity caused by people walking back and forth.
