The current pads only have height adjustment freedom and cannot adapt to the uneven areas of the bottom surface of the machine tool for fine-tuning. Its support adjustment effect needs to be further improved. Utility Model Content

DETAILED DESCRIPTION

[0018] Example 1

[0019] like Figures 1 to 4As shown, a precision spherical vibration damping washer comprises a washer shell 1 and a spherical support platform 9. A washer hole 2 is provided on the top of the washer shell 1. A sliding wedge block 3 is provided in the washer shell 1. The top wedge surface of the sliding wedge block 3 is matched with a lifting wedge block 4. A lifting column 5 is fixed to the top of the lifting wedge block 4. The lifting column 5 passes through the washer hole 2 and is fixed with a bearing plate 6. A column 7 is fixed on the bearing plate 6. A spherical concave surface 8 is provided on the top of the column 7. A spherical convex surface 10 is formed on the bottom of the spherical support platform 9. The spherical convex surface 10 is formed on the bottom of the spherical convex surface 10. 0 is adapted to fit in the spherical concave surface 8. The column 7 includes a fixed half-column 11 and a detachable half-column 12. The fixed half-column 11 is fixed to the bearing plate 6. The detachable half-column 12 is connected to the fixed half-column 11 by a bolt 13. The lifting wedge block 4 is lifted by the movement of the sliding wedge block 3, or the lifting wedge block 4 moves downward under its own gravity, thereby driving the lifting wedge block 4 to move up and down. The lifting wedge block 4 drives the bearing plate 6 up and down through the lifting column 5. The bearing plate 6 drives the spherical support platform 9 up and down through the column 7. , so that the position of the spherical support platform 9 can be adjusted, and the spherical support platform 9 and the column 7 are matched through the spherical surface, so that the spherical support platform 9 has fine-tuning freedom, can adapt to the uneven inclination angle of the bottom surface of the machine tool, and have a larger contact area between the spherical support platform 9 and the machine tool, thereby improving the supporting effect; secondly, since the spherical support platform 9 directly contacts the machine tool for support, the contact surface on the top of the spherical support platform 9 will be deformed due to long-term extrusion. At this time, the spherical support platform 9 needs to be replaced. Since the height of the machine tool lifted by the jack is limited, the space for the spherical support platform 9 in the height direction is limited. In order to facilitate the replacement of the spherical support platform 9, the column 7 is set to a split structure. When replacing, the detachable half-column 12 is removed from the fixed half-column 11, and then the spherical support platform 9 is slid out from the side. The spherical support platform 9 can be replaced using the space on the side. There is no need to move the spherical support platform 9 upward out of the spherical concave surface 8. The spherical support platform 9 can be replaced in a small space without replacing the shim as a whole, which reduces the later maintenance cost.

[0020] Furthermore, an adjusting screw 18 is rotatably provided in the solid iron shell 1, and the sliding wedge block 3 is threadedly mounted on the adjusting screw 18. The side wall of the sliding wedge block 3 contacts the inner wall of the iron shell 1. By rotating the adjusting screw 18, the sliding wedge block 3 makes a linear motion along the axial direction of the adjusting screw 18, thereby realizing the height adjustment of the spherical support platform 9.

[0021] Example 2

[0022] Based on the first embodiment, Figure 1 and Figure 2As shown, a first wing plate 14 is fixed on both sides of the fixed half-form column 11, and a second wing plate 15 is fixed on both sides of the detachable half-form column 12. A threaded hole 16 is provided on the first wing plate 14, and a through hole 17 is provided on the second wing plate 15. The tail of the bolt 13 passes through the through hole 17 and is threadedly fitted into the threaded hole 16. The fixed half-form column 11 and the detachable half-form column 12 are connected together by the bolt 13, which facilitates the installation and disassembly of the detachable half-form column 12, and further facilitates the replacement of the spherical support platform 9.

[0023] Example 3

[0024] Based on the second embodiment, Figures 1 to 4 As shown, the sliding wedge block 3 includes two half-wedge blocks, and the end faces of the two half-wedge blocks that contact each other are each provided with a half-threaded hole. The two half-threaded holes form a complete screw threaded hole, and the adjusting screw 18 thread is adapted to the screw threaded hole. The cover on the top surface of the pad iron shell 1 can be removed to remove the lifting wedge block 4, which is convenient for replacing the lifting wedge block 4. The sliding wedge block 3 is threadedly connected to the adjusting screw 18, and disassembly becomes difficult. The adjusting screw 18 needs to be removed to remove the sliding wedge block 3 for replacement. In order to facilitate the replacement of the sliding wedge block 3, the sliding wedge block 3 is set to a half-detachable structure. The two half-wedge blocks can be separated to remove the sliding wedge block 3 from the adjusting screw 18. The operation is simple and the replacement efficiency is higher.

[0025] Furthermore, if Figure 1 and Figure 4 As shown, one half of the wedge block is provided with a connecting threaded hole 19, and the other half of the wedge block is provided with a stepped countersunk hole 20. The tail end of the connecting screw 21 passes through the stepped countersunk hole 20 and is threadedly adapted in the connecting threaded hole 19. The shim shell 1 is provided with disassembly windows on both sides of the adjusting screw 18. The disassembly window is connected with a baffle by screws. The cover is removed, and then the connecting screw 21 is screwed out. Then, the half wedge block at the disassembly window is taken out, and then the other half wedge block is taken out through the other disassembly window. Then, a new sliding wedge block 3 is installed. First, half of the wedge block is adapted to the adjusting screw 18, and then the baffle is installed to limit the half wedge block. Finally, the other half wedge block is connected to the corresponding front half wedge block. The two half wedge blocks are connected together by the connecting screw 21, and finally the baffle is installed.
