Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grinding wheel electroplating equipment, and more specifically to an insulating tooling for grinding wheel electroplating. Background Technology
[0002] Electroplated grinding wheels are grinding tools made by electroplating a layer of superhard abrasive such as diamond or CBN onto the working surface of a metal substrate. Due to their special shape, butterfly grinding wheels are often used for the fine grinding and polishing of complex surfaces such as molds and gears. During the electroplating process, the grinding wheel substrate needs to be immersed in the electroplating solution as the cathode. Ideally, the abrasive should only be plated in the predetermined working area (usually the outer conical surface or end face of the grinding wheel). However, non-working areas of the grinding wheel substrate, such as the inner hole and both end faces, will also be plated with abrasive under the influence of the electric field if not insulated. This leads to a series of problems: 1. Product defects: Abrasive plating on the inner hole causes dimensional changes, making it impossible to install on the grinding machine spindle; abrasive plating on non-working end faces affects the balance and accuracy of the grinding wheel. 2. Resource waste: Expensive superhard abrasive is wasted in non-working areas. 3. Difficult subsequent processing: The plating layer in non-working areas needs to be cleaned, increasing processes and costs, and may damage the substrate.
[0003] Currently, common insulation methods involve coating non-electroplated areas with peelable rubber or applying adhesive tape. However, these methods suffer from drawbacks such as uneven insulation layer thickness, inadequate sealing at edges leading to electroplating solution seepage and "crawling," cumbersome operation, and poor repeatability. Therefore, there is an urgent need for a specialized tooling capable of providing rapid, precise, and reliable insulation to the non-working areas of a disc grinding wheel. Utility Model Content
[0004] The purpose of this utility model is to overcome the defects of the prior art and provide an insulating fixture for grinding wheel electroplating. The insulating fixture has the characteristics of simple structure, convenient clamping, reliable insulation effect and reusability.
[0005] To achieve the above and other objectives, this utility model is implemented through the following technical solution: This utility model provides an insulating fixture for grinding wheel electroplating, the insulating fixture for grinding wheel electroplating comprising:
[0006] A pair of oppositely arranged cover plates that can be snapped together to hold a grinding wheel;
[0007] At least two sealing rings are disposed on the end face of the cover plate to form a seal with the end face of the grinding wheel when the plates are fastened together.
[0008] And connectors for fastening the cover plates together.
[0009] In one embodiment, the cover plate includes a base plate, a sidewall extending from one side of the base plate, and a positioning post protruding from the central region of the base plate, wherein the sidewall and the positioning post form an annular receiving cavity.
[0010] In one embodiment, the base plate has a first groove recessed on the side facing the positioning post.
[0011] In one embodiment, a second groove is provided on the end face of the sidewall, and the sealing ring is installed in the second groove.
[0012] In one embodiment, the cover plate includes a first cover plate and a second cover plate disposed opposite to each other.
[0013] In one embodiment, the sealing ring includes a first sealing ring and a second sealing ring, with one end of the first sealing ring abutting against the first cover plate and one end of the second sealing ring abutting against the second cover plate.
[0014] In one embodiment, the cover plate is provided with a connecting hole, and the connecting element is a bolt or screw disposed in the connecting hole.
[0015] In one embodiment, the insulating fixture further includes a sealing plug located within a connection hole on the second cover plate.
[0016] In one embodiment, the insulating fixture further includes a wire, one end of which is connected to the connector.

Detailed Implementation
[0028] Please see Figures 1 to 4 The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0029] like Figure 1 As shown, this utility model provides an insulating fixture for electroplating grinding wheels. The insulating fixture includes a cover plate 1, which includes a first cover plate 11 and a second cover plate 12 disposed opposite to each other. The first cover plate 11 is located above the second cover plate 12, and the cover plate 1 has a cylindrical structure.
[0030] The cover plate 1 includes a base plate 111. A positioning post 112 and a side wall 113 are connected to one side of the base plate 111. The side wall 113 and the positioning post 112 form an annular receiving cavity 114. The receiving cavity 114 on the cover plate 1 can accommodate the main body of the grinding wheel 100. A first groove 115 is formed on one side of the base plate 111 recessed towards the positioning post 112. The positioning post 112 can be installed and positioned within the inner hole of the grinding wheel 100, and the positioning post 112 is located at the center.
[0031] like Figure 4 As shown, the cover plate 1 has a second groove 1131 on the end face of the side wall 113, and the second groove 1131 can be used to install the sealing ring 2.
[0032] like Figure 2As shown, the insulating fixture includes a sealing ring 2, which comprises a first sealing ring 21 and a second sealing ring 22. The first sealing ring 21 is disposed on the second sealing ring 22. The sealing ring 2 is located on the end face where the first cover plate 11 and the second cover plate 12 are closed. The sealing ring 2 can be an O-ring. The first sealing ring 21 is disposed against the first cover plate 11, and the second sealing ring 22 is disposed against the second cover plate 12.
[0033] The bottom plate 111 of the cover plate 1 has multiple connecting holes, and a connector 4 is installed in each connecting hole. There can be three connecting holes. The connector 4 can be a bolt or a screw.
[0034] The insulating fixture includes a sealing plug 3, which is located in the connection hole on the second cover plate 12. Specifically, the bottom of the connector 4 does not protrude from the connection hole of the second cover plate 12.
[0035] like Figure 2 As shown, the grinding wheel 100 is a butterfly-shaped grinding wheel. When the insulating fixture is in use, two cover plates 1 are fitted onto the two end faces of the grinding wheel 100. The two cover plates 1 are fixed using connectors 4 within the connecting holes, firmly clamping the butterfly-shaped grinding wheel base between the two cover plates 1. A sealing ring 2 is used to seal the contact surface between the cover plates 1 and the grinding wheel 100, isolating the inner hole and end face of the grinding wheel 100 from the electroplating solution and electric field during the electroplating process.
[0036] As shown in Figure 2, the insulating fixture includes a wire 5, one end of which is connected to the connector 4. The wire 5 connects the grinding wheel 100 to the cathode of the electroplating power supply, so that the grinding wheel 100 acts as the cathode in the electroplating solution, thereby electroplating superhard abrasive onto a preset working area.
[0037] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model.
