Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tool machining, and more particularly to a machining jig and a diamond tool machining device. BACKGROUND

[0002] The diamond grinding wheel tool is suitable for machining of hard and brittle materials such as ceramics, sapphire and glass, and has a large market demand. The production process of the diamond grinding wheel tool includes electroplating production of the diamond grinding wheel tool and sintering of the diamond grinding wheel tool. The production process of the electroplated diamond grinding wheel tool is to plate a layer of diamond abrasive on the base material rod through electroplating. Since only physical electroplating is used and the adhesion strength of the diamond abrasive is low, the diamond grinding wheel tool only has a single layer of diamond abrasive, and the service life of the diamond grinding wheel tool is very short. The production process of the sintered diamond grinding wheel tool includes material preparation (such as preparation of diamond abrasive, flux, trace elements and other raw materials), molding, sintering and welding, electrical discharge machining and laser marking. The diamond abrasive is formed in multiple layers, and after sintering and welding, the abrasive is physically bonded by the flux, and there is an interfacial reaction between the diamond and the welding and trace elements. The adhesion strength of the diamond abrasive is higher, the holding force of the abrasive on the abrasive rod base is greatly enhanced, and the sintered diamond grinding wheel tool has multiple layers of abrasive, and has a longer service life. Different abrasive sizes and processing techniques can be used to process long-life machining tools of different precision and different processing types. When the grinding wheel tool is used with a suitable machine tool to produce products, the tool changing time is reduced, the precision loss caused by tool changing is reduced, and the overall product machining efficiency, precision and cost are greatly improved.

[0003] However, during the production of the sintered diamond grinding wheel tool, the diamond grinding wheel tool will deform after sintering, and the finished product will have a large round runout error, which will affect the grinding machining precision. The tool contour needs to be machined on the electrical discharge machine, and the jig body needs to be tangentially moved with the peripheral surface of the diamond grinding wheel tool to uniformly discharge the diamond grinding wheel tool. In addition, each driver is usually paired with a set of jig bodies and diamond grinding wheel tools, which greatly affects the machining efficiency of the sintered diamond grinding wheel tool, and the cost of the electrical discharge machining equipment is high, which seriously increases the production cost.

[0040] Please refer to Figures 1 to 4 The machining jig provided by the embodiments of the present application will be described. The machining jig comprises a support assembly 70, a plurality of jig bodies 20, a transmission assembly 30 and a driver 40.

[0041] The plurality of jig bodies 20 are arranged on the support assembly 70, and the plurality of jig bodies 20 are respectively arranged corresponding to the plurality of tools to be machined 90; the transmission assembly 30 is arranged on the support assembly 70; the driver 40 is in transmission connection with the transmission assembly 30, and the driver 40 is used to drive the plurality of jig bodies 20 or the plurality of tools to be machined 90 to rotate simultaneously through the transmission assembly 30.

[0042] For example, as Figures 1 to 4As shown, the support assembly 70 is used to place the jig body 20, the transmission assembly 30 and the tool to be machined 90, and the driver 40 can also be arranged on the support assembly 70, the support assembly 70 can position the jig body 20 and the tool to be machined 90, so that the part to be machined of the tool to be machined 90 is matched with the jig body 20. The jig body 20 is correspondingly arranged with the part to be machined of the tool to be machined 90. An electrolytic reaction occurs between the tool to be machined 90 and the jig body 20, and the tool to be machined 90 and the jig body 20 also need to be connected with the opposite electrodes. The driver 40 is mainly used to provide total power output, the transmission assembly 30 is in transmission connection with the driver 40, and the transmission assembly 30 is mainly used to form a whole body of the jig body 20 or the tool to be machined 90, so that the power generated by the driver 40 can drive the jig body 20 or the tool to be machined 90, so that the relative rotation occurs between all the jig bodies 20 and all the tools to be machined 90.

[0058] Specifically, the second positioning plate 72 is arranged on the side of the first positioning plate 71 close to the tool to be machined 90, the third positioning plate 73 is horizontally arranged on the side of the second positioning plate 72 away from the first positioning plate 71, the second positioning plate 72 is provided with a third positioning hole for positioning the jig body 20, and the third positioning plate 73 is provided with a fourth positioning hole for positioning the tool to be machined 90, and the fourth positioning hole is also arranged opposite to the third positioning hole and the second positioning hole in the vertical direction, so that after the jig body 20 and the tool to be machined 90 are installed on the support assembly 70, the center axes of the jig body 20 and the tool to be machined 90 coincide with each other, and by arranging the third positioning plate 73 between the two support plates 74, the tool to be machined 90 can be quickly positioned, further improving the machining efficiency.

[0059] In an embodiment of the present application, please refer to Figure 3 and Figure 8 , the third positioning plate 73 is provided with a fixing hole 731 for fixing the tool to be machined 90 on the third positioning plate 73 by a jackscrew.
