Description

Technical Field

[0001] The utility model relates to the field of diamond electroplating, in particular to a novel auxiliary clamp for improving the uniformity of electroplating. Background Art

[0002] Electroplated diamond products have unique performance advantages in many difficult-to-process materials such as glass, ceramics, sapphire, etc. Electroplated diamond abrasives have their own unique advantages such as high concentration, high dimensional accuracy, and high surface flatness, which makes them play an important role in the processing of hard and brittle materials.

[0003] Although electroplating has good unique properties, it also has certain disadvantages. For example, the high and low potential difference that occurs during the electroplating process is also one of the industry's problems. Over the years, the industry has achieved little success by changing the electroplating formula (type and formula of main salt and additives), changing the stirring method during the electroplating process, and changing the current density of the electroplating process.

[0004] With the increasing demand for rod-shaped grinding tools in the market, the processing difficulty of such products has gradually become apparent, mainly in the following aspects: 1. It is relatively difficult to ensure the concentricity of large round rod grinding heads; 2. The working surface is longer, and the difference in high and low potentials of electroplating is more obvious; these two problems will aggravate the wear of the working surface of the grinding tool, and even cause the abrasive to fall off, resulting in the end of the life of the grinding tool, and the occurrence of adverse problems such as breakage of the workpiece being processed. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] A novel auxiliary fixture for improving electroplating uniformity includes a sleeve;

[0007] The open end of the sleeve is threadedly provided with a fixing fixture, and a clamping hole is provided in the middle of the fixing fixture;

[0008] A grinding tool is arranged inside the sleeve, and the grinding tool is a convex structure. The smaller end of the grinding tool extends outward through the clamping hole, and the clamping hole contacts the smaller end of the grinding tool and the side wall of the larger end of the grinding tool.

[0009] As a further solution of the utility model: an outer side of the fixing fixture is formed with an external thread, an inner wall of the open end of the sleeve is formed with an internal thread, and the fixing fixture is threadably matched with the sleeve through the external thread and the internal thread.

[0010] As a further solution of the utility model: the inner end of the internal thread extends inwardly to the middle of the sleeve.

[0011] As a further solution of the utility model: the larger end of the grinding tool and the inner wall of the sleeve are arranged at a distance from each other.

[0012] Compared with the prior art, the beneficial effect of the utility model is that by providing a fixed clamp, the position of the high-point potential of the grinding tool is shielded, which can reduce the density of the electroplating line at the high potential to a certain extent, and then the details are adjusted in combination with the actual effect of electroplating until a uniform electroplating surface effect is obtained, thereby effectively improving the overall flatness of the electroplated diamond surface. At the same time, the current density does not need to be reduced, and a better electroplating effect can be obtained with conventional current, thereby improving production efficiency by 30%.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0020] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The open end of the sleeve 1 is threadedly provided with a fixing fixture 2, and a clamping hole 3 is provided in the middle of the fixing fixture 2;

[0023] A grinder 4 is arranged inside the sleeve 1. The grinder 4 is a convex structure. The smaller end of the grinder 4 extends outward through the clamping hole 3. The clamping hole 3 is in contact with the smaller end of the grinder 4 and the side wall of the larger end of the grinder 4.

[0024] By extending the smaller end of the grinding tool 4 outward through the clamp hole 3, the fixing fixture 2 and the grinding tool 4 are in contact and fixed, and the grinding tool 4 is fixed in the sleeve 1 through the threaded fit between the fixing fixture 2 and the sleeve 1, the position of the high point potential of the grinding tool 4 is shielded, which can reduce the density of the electroplating line at high potential to a certain extent, and then the details are adjusted in combination with the actual effect of electroplating until a uniform electroplating surface effect is obtained, thereby effectively improving the overall flatness of the electroplated diamond surface. At the same time, the current density does not need to be reduced, and a better electroplating effect can be obtained with conventional current, thereby improving the production efficiency by 30%;

[0025] The high and low potential difference refers to the difference in electroplating efficiency at different positions of the workpiece during the electroplating process. Under the same time and current density, the electroplating rates at different positions are different. The high potential is generally manifested at the tip and the position with a smaller diameter.

[0028] As a further solution of the utility model: the inner end of the internal thread 5 extends inwardly to the middle of the sleeve 1.

[0029] The installation position of the fixing fixture 2 can be adjusted conveniently, so as to facilitate fixing of the grinding tools 4 of different sizes and specifications.

[0030] As a further solution of the utility model: the larger end of the grinding tool 4 and the inner wall of the sleeve 1 are arranged at a distance from each other.

[0031] Can ensure normal processing.
