Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding wheel dressing, in particular to a diamond grinding wheel dresser. Background Art

[0002] Diamond grinding wheel is a circular bonded abrasive with a through hole in the center, made of diamond abrasive as raw material and metal powder, resin powder, ceramic and electroplated metal as binders. It can grind hard-to-machine materials such as carbide, glass and ceramic efficiently. When using diamond grinding wheel to grind workpiece, the surface of diamond grinding wheel will gradually become uneven and asymmetrical, which will easily affect the grinding accuracy. Therefore, it is necessary to dress the grinding wheel surface with a grinding wheel dresser. When traditional diamond grinding wheel dressers are used to dress diamond grinding wheels, the dressing disc is generally installed on the electric grinding wheel by bolts. The height of the grinding wheel surface is adjusted on the rotating shaft of the machine by manual hand-held or electric push rod. The traditional diamond wheel dresser is fixed by bolts, which may cause the position of the diamond wheel to be unstable, especially when rotating at high speed, it may shake or offset, affecting the accuracy and quality of dressing, and it cannot be adaptively adjusted and fixed according to the size of the through hole diameter of the diamond wheel, which makes the flexibility of diamond wheel dressing poor. At the same time, the accuracy of adjusting the height of the grinding disc by the electric push rod is relatively low, and the height cannot be finely adjusted. For this reason, we propose a diamond wheel dresser. Utility Model Content

[0015] 1. When the grinding wheel is used to grind the workpiece for a long time, the surface of the grinding wheel will gradually become uneven and asymmetrical. Then, the grinding wheel is movably mounted on the outer surface of the fixed cylinder, and then the conical column is inserted into the interior of the fixed cylinder to contact the inclined surface of the inclined surface extrusion block until the thread groove is aligned with the internal thread groove. Then, the knob is twisted, and the knob drives the conical column to rotate. The rotation of the conical column is connected with the internal thread groove through the thread groove, thereby driving the conical column to move to the right and contact the inclined surface of the inclined surface extrusion block for extrusion. The inclined surface extrusion block slides on the upper and lower inner walls of the guide groove through the sliders at the upper and lower ends, and then from the inner part of the slide groove. The wall is continuously squeezed to the right by the conical column to expand the inclined extrusion block outward with the center of the fixed cylinder as the center, so that the rubber anti-skid strip contacts the through hole in the middle of the grinding wheel, and then the knob is continuously twisted until it is tightly contacted with the through hole in the middle of the grinding wheel, and then the through hole in the middle of the grinding wheel is used for internal support and fixation. It can provide additional support and stability, reduce the loosening and shaking of the grinding wheel during grinding, thereby improving the stability and accuracy of grinding. The friction is increased by the rubber anti-skid strip to prevent loosening. At the same time, the knob can be appropriately twisted according to the diameter of the through hole in the middle of the grinding wheel, which increases the flexibility of fixing the grinding wheel.

[0016] 2. Then the single chip microcomputer is used to control the operation of motor one.

At the same time, motor three drives the screw to rotate, and the screw is connected to the mounting plate through a thread. Then, the mounting plate is moved downward through the rotation of the screw. The mounting plate drives the grinding disk to move downward until it contacts the outer surface of the grinding wheel and starts grinding. The outer surface of the grinding wheel can be ground faster and more completely through relative rotation with the grinding wheel, and the height can be adjusted by the forward and reverse rotation of motor three according to the diameter of the grinding wheel. It can provide higher adjustment accuracy and stability, which is convenient for grinding grinding wheels of different diameters and has strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
