Description
Technical Field
[0001] The utility model relates to the technical field of shims, in particular to a shim with adjustable precision. Background Art
[0002] Machine tool shims are a common type of accessory in the prior art. When using them to install a machine tool, there is no need to set up anchor bolts to fix it to the ground. Moreover, machine tool shims have good vibration damping and a certain vertical deflection, enabling the machine tool to be stable on the ground, saving installation costs, shortening the installation period, and also allowing the machine tool position to be adjusted at any time according to production, eliminating secondary installation costs. The adjustment precision of the shim is related to the pitch of the screw and the inclination angle of the wedge block. At present, after the shim is assembled, the screw and the wedge block are not easily disassembled and do not have the ability to be disassembled and replaced, resulting in the inability to adjust the adjustment precision of the shim. When adjusting the position of the equipment or replacing the equipment in the later stage, the adjustment precision of the shim cannot meet the use requirements. At this time, the entire shim needs to be replaced. In actual use, the shim is mostly fixed to the ground by pouring, which causes difficulties in disassembling and replacing the shim. Fundamentally, it lies in the inability to adjust the adjustment precision of the shim. Content of the Utility Model

A wedge block is connected to the top of the sliding block by a fastening screw. The top inclined surface of the wedge block is in contact with an upper wedge block. The top of the upper wedge block is detachably connected to a guiding column, and the guiding column movably passes through the cover plate and is connected to a bearing platform.
[0005] Further, the wedge block is provided with a counterbore and a through hole from top to bottom. A threaded hole is opened at the top of the sliding block, and the tail of the fastening screw passes through the through hole and is threadedly fitted in the threaded hole. The screw head of the fastening screw is located in the counterbore.
[0006] Further, the detachable screw includes a main shaft and a screw. One end of the main shaft is rotatably connected to the shim housing, and a rectangular slot is opened at the other end.

Detailed Embodiment
[0017] Embodiment 1
[0018] As Figures 1 to 3As shown in the figure, an adjustable-precision shim block includes a shim block housing 1. A detachable screw 2 is arranged inside the shim block housing 1. The detachable screw 2 is rotatably connected to the shim block housing 1. The top of the shim block housing 1 is open. A cover plate 3 is connected to the top of the shim block housing 1 by screws. A sliding block 4 is threadedly sleeved on the detachable screw 2. A wedge block 6 is connected to the top of the sliding block 4 by a fastening screw 5. The top inclined surface of the wedge block 6 contacts an upper wedge block 7. A guide post 8 is detachably connected to the top of the upper wedge block 7. The guide post 8 movably passes through the cover plate 3 and is connected to a bearing platform 9. Multiple wedge blocks 6 with different inclined surface angles are configured. Similarly, each wedge block 6 is correspondingly matched with an upper wedge block 7. The wedge block 6 is detachably installed on the sliding block 4 by a fastening screw 5, which is convenient for installation and disassembly. By replacing the wedge block 6 and the upper wedge block 7, the adjustment precision of the shim block is adjusted. When it is necessary to change the adjustment precision of the shim block in the later stage, the whole shim block does not need to be replaced, reducing the operation difficulty and being able to meet the installation requirements of later equipment.
[0019] Embodiment 2
[0020] On the basis of Embodiment 1, as Figure 1 shown, the detachable screw 2 includes a main shaft 13 and a screw 14. One end of the main shaft 13 is rotatably connected to the shim block housing 1, and a rectangular slot 15 is opened at the other end. A plug-in block 16 is coaxially fixed at one end of the detachable screw 2. The plug-in block 16 is fitted in the rectangular slot 15. The screw 14 is assembled in a detachable manner. When the cooperation between the upper wedge block 7 and the wedge block 6 cannot meet the precision requirements, the screw 14 can be replaced. Multiple screws 14 with different pitches are configured. The connection between the main shaft 13 and the screw 14 is completed by plugging. By rotating the main shaft 13, the screw 14 is driven to rotate, so that the sliding block 4 thereon drives the wedge block 6 to move. The wedge block 6 drives the guide post 8 to move up and down through the cooperation with the upper wedge block 7, and then drives the bearing platform 9 to move up and down. The movement precision of the bearing platform 9 is adjusted by replacing the screw 14.
[0021] Furthermore, the wedge block 6 is provided with a counterbore 10 and a through hole 11 from top to bottom. A threaded hole 12 is opened at the top of the sliding block 4. The tail of the fastening screw 5 passes through the through hole 11 and is threadedly fitted in the threaded hole 12. The head of the fastening screw 5 is located in the counterbore 10. The head of the fastening screw 5 is hidden in the counterbore 10, so that the upper wedge block 7 can fit well with the wedge block 6.
[0022] Embodiment 3
[0023] On the basis of Embodiment 2, as Figure 1As shown, a disassembly window 17 is provided on the side wall of the shim shell 1. A side cover plate 18 is arranged in the disassembly window 17. The side cover plate 18 is connected to the shim shell 1 by screws. A bearing 19 is installed at one end of the side cover plate 18 close to the screw rod 14. One end of the screw rod 14 far from the main shaft 13 coaxially penetrates into the inner ring of the bearing 19. By removing the side cover plate 18, the screw rod 14 can be removed together with the sliding block 4, realizing the removal of the screw rod 14. During assembly, the insertion block 16 of the screw rod 14 is inserted into the rectangular slot 15, and then the side cover plate 18 is installed, so that one end of the screw rod 14 far from the main shaft 13 penetrates into the inner ring of the bearing 19 and contacts the side cover plate 18. The side cover plate 18 prevents the screw rod 14 from detaching from the main shaft 13. At the same time, the setting of the bearing 19 does not affect the rotational freedom of the screw rod 14.
[0024] Embodiment Four
[0025] On the basis of Embodiment Three, as Figures 1 to 3 shown, a positioning groove 20 is provided at the top of the upper wedge block 7. The bottom of the guide post 8 is fitted in the positioning groove 20. A horizontal limiting hole 21 is provided on the side wall of the guide post 8. A limiting rod 22 penetrates through the side wall of the upper wedge block 7. The limiting rod 22 penetrates into the limiting hole 21. A threaded hole 23 is provided on the side wall of the upper wedge block 7. The threaded hole 23 communicates with the positioning groove 20. The limiting rod 22 is threadedly fitted in the threaded hole 23. A nut is fixedly installed at the first end of the limiting rod 22 far from the guide post 8. The upper wedge block 7 and the guide post 8 are detachably connected. When replacing the wedge block 6, the upper wedge block 7 needs to be replaced correspondingly. At this time, only by unscrewing the limiting rod 22, the upper wedge block 7 and the guide post 8 can be disassembled, and the corresponding upper wedge block 7 can be replaced and connected by the limiting rod 22.
