Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of trimmer, in particular to a geometric method instead of algebraic calculation to trim the guide wheel generatrix of the best contact line length of the guide wheel surface and the workpiece generatrix, and the grinding wheel guide wheel can share the grinding wheel guide wheel shared trimmer. BACKGROUND
[0002] The traditional grinding wheel and guide wheel trimmer of centerless grinding machine are independent, and the grinding wheel trimmer is fixed. The guide wheel trimmer can be adjusted in the parallel plane of the guide wheel axis. When straight-through grinding, the guide wheel is inclined backward to transport the product. The guide wheel generatrix in contact with the product needs to be trimmed into a hyperbola to maximize the contact with the product generatrix. The traditional guide wheel generatrix hyperbola has a mature algebraic equation for accurate calculation, but it has been a difficult problem in practice to trim the calculated hyperbola. The core problem of the traditional "hyperbolic" trimming method is the algebraic thinking mode of "calculation first and trimming later". Although accurate calculation is made, it has no guiding significance for actual operation. The operator can only adjust the horizontal angle of the guide wheel trimmer by experience estimation method to trim the approximate guide wheel generatrix hyperbola, because the backward inclination angle of the guide wheel and the horizontal angle of the trimmer cannot be accurately positioned. The trimmed guide wheel generatrix often needs to be repeatedly tested and trimmed several times to trim the approximate guide wheel generatrix hyperbola. This method can grind qualified products, but it still has the following defects in controlling the precision and process stability of the product: 1. Complex adjustment: The setting and adjustment of the trimmer angle require high skill of the operator and are prone to human error.
[0003] 2. Low efficiency: Due to the limitation of the function of the trimmer itself, the theoretically calculated hyperbola cannot be accurately trimmed. The angle of the trimmer can only be adjusted by experience estimation, and the contact degree of the guide wheel surface and the product generatrix needs to be verified several times.
[0004] 3. Difficulty in ensuring parallelism: The grinding wheel and the guide wheel use two independent trimmers, which makes it difficult to maintain strict parallelism between the grinding wheel and the guide wheel and the product contact line during long-term use, affecting the grinding quality and stability.
[0005] Therefore, we propose a new type of grinding wheel and guide wheel shared trimmer. SUMMARY
[0006] The purpose of the present application is to solve the problems of complex adjustment, low efficiency and difficulty in ensuring parallelism in the existing trimmer, and to propose a grinding wheel and guide wheel shared trimmer.
[0007] In order to achieve the above purpose, the present application adopts the following technical scheme: The grinding wheel guide wheel shared dresser comprises a dresser body, a three-axis servo mechanism is arranged on the dresser body, the Z-axis of the three-axis servo mechanism is arranged between the guide wheel and the grinding wheel guide wheel, and a diamond pen is arranged at the tail end of the Z-axis.
[0008] Preferably, the bottom of the dresser body is provided with a permanent magnetic suction disc with a switch, which facilitates quick installation and use on existing centerless grinding machines. The X-axis and Y-axis of the three-axis servo mechanism must be parallel to the horizontal plane of the grinding wheel axis, and the X-axis must be parallel to the end surface of the grinding wheel.
[0009] In the present application, the grinding wheel guide wheel shared dresser controls the running track of the diamond pen through the three-axis servo mechanism to dress the grinding wheel and the guide wheel. The core principle is that the diamond pen runs in a straight line parallel to the main shaft of the grinding wheel in the horizontal plane parallel to the grinding wheel axis, and the guide wheel rotates and is dressed by the diamond pen, so that a curve identical to the track of the diamond pen is formed on the surface of the guide wheel. The dresser body of the present scheme realizes numerical control programming and automatic dressing, without complex algebraic operations, experimental experience estimation and repeated debugging, and is simple, fast and accurate to operate. Regardless of the change of the backward inclination angle of the guide wheel, the accurate formation of the contact straight line between the guide wheel and the product generatrix is not affected. In the cutting-in grinding, the dresser body can also dress the grinding wheel and the guide wheel to form various complex steps, inclined surfaces, arc surfaces and the like through programming.

[0016] In the present application, the dresser must be calibrated first when in use, i.e. the X axis 6 and the Y axis 5 of the dresser are parallel to the horizontal plane of the axis of the grinding wheel 2, and then the X axis 6 is parallel to the end surface of the grinding wheel 2. The diamond pen is arranged to run in a straight line parallel to the spindle of the grinding wheel in the horizontal plane parallel to the axis of the grinding wheel, and the guide wheel is rotated by the diamond pen.
