Abstract
Description
Technical Field
[0001] The present application relates to the technical field of grinding tools, and in particular to a diamond dressing roller. Background Art
[0002] A grinding wheel is a high-efficiency, high-precision tool used for mass-produced grinding of parts, and a diamond dressing roller is a tool used for grinding and shaping grinding wheels. It is often used as a dressing tool for mass-produced grinding wheels. The working principle is to shape and dress the ordinary ceramic bonded corundum grinding wheel used for grinding through a diamond roller installed on a grinding machine. After the grinding wheel is dressed and shaped, the parts are ground. The outer contour and precision dimensions of the dressing roller are copied to the surface of the part to be processed through the grinding wheel to ensure accuracy. Diamond dressing rollers generally include cup type, cone type, tap type, guide rail type and angle grinding type. Different diamond dressing rollers have different shapes.
[0003] The diamond dressing roller needs to be fixed to the spindle during use. Due to the continuous contact of high-speed grinding, the temperature of the diamond dressing roller increases. The conventional method is to cool it by continuously injecting coolant into the grinding position, but it can only cool down locally. After long-term processing, the temperature of the diamond dressing roller body will increase, affecting its use.
[0004] There are also some products on the market that can cool the diamond dressing roller body, such as the Chinese patent with publication number CN217914791U and authorization date of November 29, 2022, which discloses a diamond roller for grinding bearing grooves, including a roller body, a first circulation groove and a second circulation groove are opened inside the roller body, and the first circulation groove and the second circulation groove are arranged in an inclined shape inside the roller body, and a flow groove connected to the first circulation groove and the second circulation groove is opened inside the roller body.
[0005] In this application, when the roller body is rotated for grinding, the coolant inside the first circulation groove enters the inside of the flow groove and the second circulation groove. Through the mutual cooperation of the first circulation groove, the second circulation groove and the flow groove, the coolant inside the roller body can circulate, so that the coolant can fully cool the heat generated by the roller body, making the circulation of the coolant smoother. However, the inventor believes that the structure of this application is relatively complicated, and the mechanism set inside it will also affect the balance of the roller. Therefore, it is necessary to design a diamond dressing roller with a simple structure and good heat dissipation effect. Utility Model Content
