Description

Technical Field

[0001] This utility model relates to the field of electroplated diamond grinding head technology, specifically a tooling fixture for electroplated diamond grinding heads. Background Technology

[0002] Electroplated diamond grinding heads have extremely high hardness and can easily meet the grinding needs of various hard materials. They are widely used in the processing of hard materials such as optical lenses, prisms, watch glass, and sapphire glass. When using electroplated diamond grinding heads, they are usually used in conjunction with tooling fixtures.

[0003] In the machining process, some existing tooling fixtures may have insufficient clamping force due to unreasonable design of the clamping mechanism or improper adjustment of the clamping force. This may cause the workpiece to loosen or fall off during the machining process, resulting in poor positioning and fixing effect.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent application number: 201720250340.9, application date: 2017.11.28) discloses a fixture for machining diamond grinding heads. This fixture positions the base body by precision machining and further precision machining the base body to ensure that the base body meets the machining dimensions. The method has a short clamping time, small and stable runout value, convenient dimensional measurement, no wear of measuring tools, and convenient clamping. It realizes rapid positioning of diamond grinding heads in lathe machining, improves production efficiency, reduces measuring tool wear, and reduces production costs.

[0005] While existing technologies can solve the problem of rapid positioning of diamond grinding heads, the fixtures lack versatility and cannot adapt to diamond grinding heads of different sizes. This makes it impossible to fix and install electroplated diamond grinding heads of different sizes and specifications, reducing the practicality of the tooling fixtures. Furthermore, the positioning base of the precision machining fixture does not have an anti-slip protective structure, which cannot further increase the stability of the grinding head and also increases the vibration and wear of the grinding head during the processing.

[0006] Therefore, we proposed a tooling fixture for electroplated diamond grinding heads that can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a tooling fixture for electroplated diamond grinding heads, in order to solve the problems mentioned in the background art. Currently available fixtures lack versatility and cannot adapt to diamond grinding heads of different sizes, thus failing to fix and install electroplated diamond grinding heads of different sizes and specifications, reducing the practicality of the tooling fixture. Furthermore, the positioning base of the precision machining fixture lacks an anti-slip protective structure, which cannot further increase the fixation of the grinding head and also increases the vibration and wear of the grinding head during the processing.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for electroplating diamond grinding heads, comprising a grinding machine body, wherein the output shaft of the grinding machine body passes through a fixture frame via a coupling, a guide cover is fixedly installed at the bottom of the fixture frame, and an electroplating diamond grinding head body is disposed inside the fixture frame;

[0009] It also includes: a rotating plate is provided on the inner wall of both sides of the fixture frame, a support plate is fixedly installed on the top of the rotating plate, a dual-axis motor body is provided in the middle of the support plate, and a screw is fixedly installed on the output shaft of the dual-axis motor body through a coupling, and the end of the screw is connected through the support plate.

[0010] The screw is fitted with a threaded sleeve plate on its outer wall. A clamping plate is fixedly installed at the bottom of the threaded sleeve plate. An anti-slip pad is fixedly connected to the inner wall of the clamping plate and is located on the outer wall of the electroplated diamond grinding head.

[0011] As a preferred technical solution of this application, a rotating shaft is provided at the rear of the support plate, a protective cover is fitted on the outer wall of the rotating shaft, and a handle is fixedly connected to the front of the protective cover.

[0012] As a preferred technical solution of this application, the protective cover has symmetrically opened grooves on the front and rear sides, and a slider is provided inside the groove. The end of the slider is fixedly connected to a threaded sleeve plate. During the movement of the threaded sleeve plate, the slider is driven to slide in the corresponding groove, thereby increasing the stability of the movement of the threaded sleeve plate.

[0013] As a preferred technical solution of this application, through holes are provided inside the upper and lower sides of the rotating plate, and a telescopic rod passes through the through hole. The end of the telescopic rod passes through and is connected to the clamping plate. Six springs are fixedly connected to the right side of the clamping plate.

[0014] As a preferred technical solution of this application, the rotating plate and the through hole are integrated, and the telescopic rod and the through hole are movably connected. The rotating plate and the grinder body are fixedly connected. During the movement of the clamping plate, the telescopic rod is driven to move in the corresponding through hole, while the spring is stretched or compressed to increase the stability of the movement of the clamping plate.

[0015] As a preferred technical solution of this application, the clamping plate and the anti-slip pad are tightly fitted together, and the anti-slip pad is made of rubber. The clamping plate and the rotating plate are fixedly connected to both ends of the spring. Since the anti-slip pad is made of rubber, it has elasticity and anti-slip effect, which can not only fix the grinding head more firmly, but also reduce the vibration and wear of the grinding head during the processing to a certain extent.

[0016] As a preferred technical solution of this application, the protective cover and the rotating shaft are tightly fitted together, and the rotating shaft and the support plate are rotatably connected. By having the operator hold the handle tightly and move the protective cover upward, the protective cover drives the rotating shaft to rotate on the support plate, thereby opening the protective cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This tooling fixture for electroplated diamond grinding heads, equipped with a screw and clamping plate, can fix and install electroplated diamond grinding heads of different sizes. It also features anti-slip pads to increase the stability of the grinding heads and reduce vibration and wear during processing. Furthermore, it includes a protective cover and a rotating shaft, which can be opened to expose the internal dual-axis motor body and screw components for inspection, maintenance, or replacement.

[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 The present invention provides the following technical solution:

[0032] Example 1: To address the shortcomings of existing fixtures on the market, such as their lack of versatility in accommodating diamond grinding heads of varying sizes, thus hindering the secure mounting of electroplated diamond grinding heads of different dimensions and reducing the practicality of tooling fixtures, and the absence of anti-slip protective structures on the positioning base of precision machining fixtures to further enhance grinding head stability and increase vibration and wear during machining, please refer to the attached... Figure 1 - Appendix Figure 5The system includes a grinder body 1, whose output shaft passes through a clamping frame 2 via a coupling. A guide cover 3 is fixedly installed at the bottom of the clamping frame 2, and an electroplated diamond grinding head body 4 is disposed inside the clamping frame 2. It also includes: rotating plates 5 disposed on the inner walls of both sides of the clamping frame 2; a support plate 11 fixedly installed on the top of the rotating plates 5; a dual-axis motor body 14 disposed in the middle of the support plate 11; a screw 15 fixedly installed on the output shaft of the dual-axis motor body 14 via a coupling, with the end of the screw 15 passing through and connected to the support plate 11; a threaded sleeve plate 16 sleeved on the outer wall of the screw 15; a clamping plate 8 fixedly installed at the bottom of the threaded sleeve plate 16; an anti-slip pad 10 fixedly connected to the inner wall of the clamping plate 8, and the anti-slip pad 10 located on the outer wall of the electroplated diamond grinding head body 4. A protective cover 13 has symmetrically opened grooves 18 on its front and rear sides, with sliders 17 disposed inside the grooves 18, and the ends of the sliders 17 fixedly connected to the threaded sleeve plates 16. The rotating plate 5 has through holes 6 on its upper and lower sides. A telescopic rod 7 passes through the through holes 6, and the end of the telescopic rod 7 is connected to a clamping plate 8. Six springs 9 are fixedly connected to the right side of the clamping plate 8. The rotating plate 5 and the through holes 6 are integrated, while the telescopic rod 7 is movably connected to the through holes 6. The rotating plate 5 is fixedly connected to the grinder body 1. The clamping plate 8 and the anti-slip pad 10 are tightly fitted together, and the anti-slip pad 10 is made of rubber. The two ends of the springs 9 are fixedly connected to the clamping plate 8 and the rotating plate 5.

[0033] The electroplated diamond grinding head body 4 to be processed is manually placed between two clamping plates 8 by the staff. Depending on the size of the electroplated diamond grinding head body 4, the external control board activates the dual-axis motor body 14. The output shaft of the dual-axis motor body 14 drives the screw 15 to rotate, causing the screw 15 to move the corresponding threaded sleeve 16 horizontally, either close to or far from it. During the movement of the threaded sleeve 16, the slider 17 slides within the corresponding groove 18, increasing the stability of the threaded sleeve 16's movement. This, in turn, causes the threaded sleeve 16 to move the clamping plates 8. The clamping plate 8 moves, causing the anti-slip pad 10 to adhere to both sides of the electroplated diamond grinding head body 4 for fixation. During the movement of the clamping plate 8, the telescopic rod 7 moves within the corresponding through hole 6, while simultaneously stretching or compressing the spring 9 to increase the stability of the clamping plate 8's movement. The anti-slip pad 10, made of rubber, has elasticity and anti-slip properties, which not only more firmly fixes the grinding head but also reduces vibration and wear of the grinding head during processing to a certain extent. This allows for the fixed installation of electroplated diamond grinding heads of different sizes and specifications, facilitating subsequent processing.

[0034] Example 2: The protective cover 13 can be opened, as shown in the attached document. Figure 1 - Appendix Figure 6A rotating shaft 12 is provided behind the support plate 11. A protective cover 13 is fitted on the outer wall of the rotating shaft 12. A handle 19 is fixedly connected to the front of the protective cover 13. The protective cover 13 and the rotating shaft 12 are tightly fitted together, and the rotating shaft 12 and the support plate 11 are rotatably connected.

[0035] By having the staff firmly grasp the handle 19, the protective cover 13 is moved upward, causing the protective cover 13 to drive the rotating shaft 12 to rotate on the support plate 11, thereby opening the protective cover 13 and exposing the internal dual-axis motor body 14 and screw 15 and other components, so that the staff can inspect, repair or replace them.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
