Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a grinding device for reducing wear on grinding wheels. Background Technology

[0002] A grinding machine is a grinding machine that uses abrasive-coated or embedded grinding wheels to grind the surface of a workpiece. It is mainly used for grinding high-precision flat surfaces, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces, and other profiled surfaces of workpieces. Currently, in traditional grinding machines, the grinding disc for loading the workpiece is placed directly on the grinding wheel. For example, Chinese patent CN201922389763.0 discloses a single-sided grinding machine, which includes a grinding disc, a carrier disc, and a pressure grinding disc. The carrier disc is placed on the grinding disc and is used to hold the workpiece. The pressure grinding disc is located above the carrier disc and includes a concentrated pressure ball, which is installed in the center hole of the workpiece. The pressure grinding disc presses against the concentrated pressure ball. This grinding machine ensures uniform grinding of the workpiece through the contact between the pressure grinding disc and the concentrated pressure ball. However, since the carrier disc is placed directly on the grinding disc, relative rotation occurs between the carrier disc and the grinding disc while the grinding machine is grinding the workpiece, leading to wear on the grinding disc and reducing the service life of both the grinding disc and the carrier disc. Summary of the Invention

[0003] In view of this, the present invention provides a grinding device for reducing wear of grinding wheels to solve the above problems.

[0004] A grinding apparatus for reducing grinding wheel wear includes a grinding machine, at least three lifting assemblies disposed on the grinding machine, and three grinding disc assemblies respectively disposed on the three lifting assemblies. Each lifting assembly includes at least two adjusting blocks fixedly disposed on the grinding machine and located on one side of the grinding wheel, a support plate disposed on one side of the adjusting blocks, and at least three bearings spaced apart on the side of the support plate facing the grinding machine. Each grinding disc assembly includes a grinding disc and a feed tray disposed within the grinding disc. The grinding machine has a rotary motor inside, the output end of which is connected to a grinding wheel. Each adjusting block has at least two adjusting grooves, the length of which is perpendicular to the plane of the grinding wheel. The support plate is fixed to the adjusting blocks by screws and washers.

[0005] Furthermore, a circular groove is provided on the support plate, which corresponds to the grinding disc.

[0006] Furthermore, three screws for fixing the bearings are respectively provided on the support plate at the positions corresponding to the three bearings.

[0007] Furthermore, the bearing protrudes from the support plate on the side facing the grinding disc. Furthermore, the grinding disc is a hollow, flat cylinder.

[0008] Furthermore, a stepped portion protrudes from the outer circumferential wall of the grinding disc.

[0009] Furthermore, the tray is provided with a number of material holes spaced apart for placing materials.

[0010] Furthermore, the grinding device for reducing wear of the grinding wheel also includes a tool holder disposed on one side of the grinding wheel, which clamps a dressing tool toward the center of the grinding wheel.

[0011] Compared with the prior art, the grinding device for reducing wear of grinding wheels provided by this utility model fixes the support plate to the adjusting block with screws and washers, and adjusts the distance between the support plate and the grinding wheel through the adjusting groove. The grinding disc is mounted on the part of the bearing that protrudes from the support plate through the stepped part. In this way, when the material is placed in the grinding disc assembly, the pressure roller presses down, ensuring that the material abuts against the surface of the grinding wheel while avoiding contact between the grinding disc and the grinding wheel. This effectively reduces the wear of the grinding wheel during the grinding operation and improves the service life of the grinding wheel and the grinding disc. Attached Figure Description

[0013] Figure 2 for Figure 1 A schematic diagram of the structure of the grinding device lifting component and grinding disc component to reduce grinding wheel wear. Detailed Implementation

[0014] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0015] like Figure 1 The diagram shows the structure of the grinding device for reducing grinding wheel wear provided by this utility model. The grinding device includes a grinding machine 10, at least three lifting components 20 disposed on the grinding machine 10, and three grinding disc assemblies 30 respectively disposed on the three lifting components 20. It is conceivable that the grinding device for reducing grinding wheel wear also includes other functional modules, such as a power supply module for providing power, a pressure roller for stabilizing materials, a screw washer module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0016] The grinding machine 10 is a machine tool that uses an abrasive to grind the surface of a workpiece. The grinding machine 10 has a rotary motor inside, and a grinding wheel 11 is connected to its output end. The grinding wheel 11 rotates under the drive of the rotary motor, thereby performing grinding operations on the material abutting against the surface of the grinding wheel 11.

[0017] Please see Figure 2 The lifting assembly 20 includes at least two adjusting blocks 21 fixedly mounted on the grinding machine 10 and located on one side of the grinding wheel 11, a support plate 22 disposed on one side of the adjusting blocks 21, and at least three bearings 23 spaced apart on the side of the support plate 22 facing the grinding machine 10.

[0018] The adjusting block 21 has at least two adjusting grooves 24, the length direction of which is perpendicular to the plane of the grinding wheel 11. The support plate 22 is fixed to the adjusting block 21 by screws and washers. The screws can be positioned along the length direction of the adjusting grooves 24 to adjust the distance between the support plate 22 and the grinding wheel 11. In this way, after the material is placed in the grinding disc assembly 30, it can ensure that the material abuts against the surface of the grinding wheel 11 while avoiding contact between the grinding disc assembly 30 and the grinding wheel 11, effectively reducing the wear of the grinding wheel 11 during the grinding operation.

[0019] A circular groove is formed on the support plate 22, which corresponds to the grinding disc assembly 30. Three screws are respectively provided on the support plate 22 at the positions corresponding to the three bearings 23 to fix the bearings 23. The bearings 23 protrude from the support plate 22 on the side facing the grinding disc assembly 30 to support the grinding disc assembly 30.

[0020] The grinding disc assembly 30 includes a grinding disc 31 and a material tray 32 disposed within the grinding disc 31.

[0021] The grinding disc 31 is a hollow, flat cylinder, the hollow part of which is used to fix the material tray 32. A stepped portion 33 is provided on the outer circumferential wall of the grinding disc 31. The stepped portion 33 is used to support the part of the bearing 23 that protrudes from the support plate 22, thus supporting the grinding disc 31 so that the grinding disc 31 is mounted above the grinding wheel 11.

[0022] The material tray 32 is provided with a plurality of material holes 34 spaced apart. The material holes 34 are used to place the wafer-shaped material. When the pressure roller presses on the material tray 32, the material can be pressed onto the grinding wheel 11 on the side facing the grinding wheel 11, thereby performing a grinding operation on the material.

[0023] The grinding device for reducing grinding wheel wear also includes a tool holder 40 disposed on one side of the grinding wheel 11, which clamps a dressing tool (not shown) towards the center of the grinding wheel 11. This dressing tool is used to correct the surface of the grinding wheel 11, remove wear particles, and maintain the flatness of the grinding wheel 11 to ensure machining accuracy. Compared with the prior art, the grinding device for reducing wear of grinding wheels provided by this utility model fixes the support plate 22 on the adjusting block 21 with screws and washers, and adjusts the distance between the support plate 22 and the grinding wheel 11 through the adjusting groove 24. The grinding disc 31 is mounted on the part of the bearing 23 that protrudes from the support plate 22 through the stepped part 33. In this way, when the material is placed in the grinding disc assembly 30, the pressure roller presses down, which ensures that the material abuts against the surface of the grinding wheel 11, while avoiding contact between the grinding disc 31 and the grinding wheel 11. This effectively reduces the wear of the grinding wheel 11 during the grinding operation and improves the service life of the grinding wheel 11 and the grinding disc 31.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
