Description

Technical Field

[0001] The utility model relates to the technical field of diamond rollers, in particular to a diamond roller. Background Art

[0002] Diamond roller is a high-efficiency, high-life, low-cost grinding wheel dressing tool for special machine tools and gear grinders for mass-produced profile grinding. It is mainly used to dress corundum and silicon carbide grinding wheels with complex surfaces. Diamond rollers are now being used in the field of profile grinding. Diamond rollers are installed on the dressing device of the grinding machine to dress ordinary ceramic grinding wheels or CBN grinding wheels. After the grinding wheel is formed, the parts are ground, so that the shape, precision and size of the diamond roller are copied to the surface of the processed parts through the grinding wheel. Its characteristics are simple machine operation, low technical requirements for operators, good precision consistency of processed products, stable quality, which can significantly improve production efficiency and product quality, reduce manufacturing costs, and easily realize grinding automation. Compared with traditional single-point diamond pen dressing, production efficiency is greatly improved, and the surface quality and precision of the processed parts are higher, which is particularly suitable for high-precision and mass production.

[0003] Diamond rollers are made by embedding a large number of diamond particles on the surface of steel rollers through electroplating and powder metallurgy, rotating at a certain speed, and producing grinding and rolling effects on the surface of high-speed grinding wheels, so that the grinding wheel can obtain a sharp working surface consistent with the profile of the diamond roller. Diamond rollers are complex to manufacture and costly, but they are durable and have high correction efficiency. They are high-efficiency, high-life, and low-cost grinding wheel dressing tools for special machine tools and gear grinders for large-scale shaping grinding.

[0004] For example: Chinese utility model with application number: 202020586460.8, a diamond roller capable of improving heat dissipation performance, the device includes a mounting frame, the outer surface of the mounting frame is provided with a plurality of mounting holes, the outer surface of the mounting frame is provided with a mounting groove located in the middle of the plurality of mounting holes, a storage frame is fixedly installed on the top of one end of the mounting frame, storage rods are fixedly installed on both sides of the storage frame, and the outer surface of the mounting hole is movably sleeved with a diamond roller body. In the specific use process of the utility model, the mounting hole, the mounting groove and the telescopic sleeve II cooperate with each other, so that no threaded connection is required when installing the diamond roller, which facilitates the adjustment of the diamond roller; the mounting frame is tightened by setting a telescopic spring and a clamping plate, so that the diamond roller is shock-absorbing while the diamond roller is working, thereby improving the stability of the diamond roller when working.

[0005] Although the above-mentioned device can facilitate the adjustment and stability of the diamond roller by telescopic springs, rope sleeves, etc., the above-mentioned device still needs to be improved during use. The above-mentioned device can adjust the distance between the diamond rollers, but cannot grind workpieces of different thicknesses at the same time. The entire grinding wheel needs to be replaced, and the operation is relatively cumbersome. Utility Model Content

[0020] Preferably, the number of the multiple grinding components is at least one.

[0021] Compared with the related art, the diamond roller provided by the utility model has the following beneficial effects:

[0022] 1. When replacing workpieces of different thicknesses, there is no need to replace the entire device. You only need to pull out the mounting plate to move the connecting column out of the mounting holes of the first fixing ring, the second fixing ring, the third fixing ring, and the grinding plate. Adjust the first fixing ring, the second fixing ring, and the third fixing ring according to the thickness you need, and then install grinding plates of different sizes and mounting plates of different sizes to adapt to different workpieces.

[0023] 2. When different workpieces need to be polished, you only need to install the first rotating rod and the second rotating rod, then you will get the magic rod, and then install the magic rod on the output end of the servo motor. Because the thickness of the entire multiple polishing assembly can be adjusted manually, the multiple polishing assembly on the first rotating rod and the second rotating rod can polish two different workpieces at the same time. At this time, there is only one power source for polishing two different workpieces, so that the same power source can be used to polish two workpieces of different sizes or the same size.
