Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a grinding machine vibration damping device and a grinding machine. Background Technology

[0002] Grinding machines are key pieces of equipment in machining, used for precision grinding. They use a high-speed rotating grinding wheel to cut the surface of a workpiece, thereby improving its dimensional accuracy. During operation, the high-speed rotation of the grinding wheel in contact with the workpiece generates vibrations. Vibration-absorbing devices function to absorb or isolate these vibrations, reducing their impact on machining accuracy and the equipment itself.

[0003] The existing patent publication number CN218476321U discloses a shock-absorbing CNC gantry machine tool base, which includes a support plate, a shock-absorbing mechanism, and a machine tool base. The shock-absorbing mechanism includes a damper and a fixed seat. The fixed seat has an installation groove, and the damper is disposed in the installation groove. The damper is connected to the support plate, and the bottom surface of the fixed seat is fixed to the machine tool base. The shock-absorbing mechanism is disposed between the support plate and the machine tool base to ensure the stability of the machine tool and guarantee the machining accuracy of the machine tool.

[0004] The aforementioned base buffers machine tool vibration in the vertical direction through a damper, but it cannot be specifically adapted to the machine tool. Vibration from the grinding machine is transmitted to the damper, resulting in unstable deformation at various points and affecting machining accuracy. To address these issues, a grinding machine vibration absorption device and a grinding machine are proposed. Utility Model Content

[0030] 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.

[0031] Please see Figures 1-6 In this embodiment, a grinding machine vibration damping device includes...

[0032] The shock-absorbing seat 1 includes a seat body 11 and an annular shock-absorbing pad 12 connected to the bottom of the seat body 11. The annular shock-absorbing pad 12 is in direct contact with the placement surface. When the grinding machine body 5 vibrates during operation, the annular shock-absorbing pad 12 absorbs part of the vibration energy through its own elastic deformation.

[0033] The connecting seat 2 includes a central block 21, a threaded ring 22 connected to the bottom of the central block 21 and threadedly engaged with the pad body 11, a lever 23 connected to the outer wall of the central block 21, a reinforcing ring 24 connected to the bottom of the lever 23, and a rubber washer 25 connected to the top of the central block 21; the threaded ring 22 rotates on the pad body 11 to adjust the height of the central block 21;

[0034] Mounting member 3 is mounted on center block 21; and stabilizing member 4 includes wedge block 41 placed between reinforcing ring 24 and pad body 11, wherein one side of pad body 11 is connected to adjusting member for adjusting the distance between wedge block 41 and threaded ring 22.

[0035] Please see Figure 5 The outer wall and top of the annular shock-absorbing pad 12 are connected with several raised rings, and the inner wall of the pad body 11 is provided with an annular groove that engages with the raised rings; the engagement between the raised rings and the annular groove on the inner wall of the pad body 11 enhances the connection stability between the two, ensures that the structure is not easily loosened during shock absorption, and further improves the shock absorption effect.

[0036] Please see Figure 4 The inner wall of the pad body 11 is provided with a threaded groove 13 that is threaded to the outer wall of the threaded ring 22; the threaded ring 22 of the connecting seat 2 is threaded to the threaded groove 13 on the inner wall of the pad body 11, realizing the initial connection between the connecting seat 2 and the shock-absorbing seat 1. At the same time, the height of each connecting seat 2 on the shock-absorbing seat 1 can be adjusted according to the placement position of the grinding machine.

[0037] Please see Figure 3 The lever 23 is provided in four sets, and the four sets of levers 23 are arranged in a circular array; personnel can rotate the reinforcing ring 24 by turning the lever 23.

[0038] Please see Figure 6 The mounting component 3 includes a mounting screw 31 and a nut 32 threaded onto the mounting screw 31, and the center block 21 is provided with a through hole for the nut 32 to pass through.

[0039] Please see Figure 4 The adjusting component includes an L-shaped block 42 connected to the annular outer wall of the pad body 11, an adjusting screw 43 rotatably connected to the L-shaped block 42, and a wedge block 41 threadedly connected to the adjusting screw 43. Specifically, by rotating the adjusting screw 43, the position of the wedge block 41 can be changed. By utilizing the sliding fit between the bottom of the wedge block 41 and the tapered inclined surface at the top of the pad body 11, as well as the contact between the top of the wedge block 41 and the reinforcing ring 24, stable support for the adjusted connecting seat 2 can be achieved, so that the device remains stable after adjustment.

[0040] Furthermore, the top of the wedge block 41 is a flat surface, and the bottom of the wedge block 41 slides in contact with the tapered inclined surface at the top of the pad body 11. After the height of the center block 21 is adjusted, the adjustable wedge block 41 can slide horizontally along the top of the pad body 11. When the center block 21 is raised, the adjustable wedge block 41 slides closer to the threaded ring 22. When the center block 21 is lowered, the adjustable wedge block 41 slides further away from the threaded ring 22.

[0041] Please see Figure 7A grinding machine includes a grinding machine body 5 and a grinding machine shock absorption device, wherein the rubber gasket 25 contacts the bottom of the grinding machine body 5, and the center block 21 is fixed to the top of the grinding machine body 5 by a mounting member 3;

[0042] The grinding machine body 5 is installed through a grinding machine vibration absorption device. The rubber gasket 25 contacts the bottom of the grinding machine body 5 to provide a buffering effect. The center block 21 is fixed to the top of the grinding machine body 5 through the mounting part 3, so that the grinding machine body 5 and the vibration absorption device form an integral whole. This ensures that the vibration of the grinding machine can be effectively transmitted to the vibration absorption device and absorbed when the grinding machine is working. Through vibration, the stability of the grinding machine body 5 during operation is guaranteed, the accuracy of the processed parts is improved, the service life of the grinding machine is extended, and the grinding machine can perform processing work more efficiently and stably.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
