Description

Technical Field

[0001] The utility model relates to the technical field of surface grinders, in particular to a numerically controlled precision surface grinder with a grinding wheel adjustment mechanism. Background Art

[0002] The angle of the grinding wheel determines the contact area and grinding force distribution during grinding, which directly affects the surface roughness and shape accuracy of the workpiece. The appropriate grinding wheel angle can ensure the uniformity and consistency of the grinding surface and improve the processing quality of the workpiece. If the angle is not selected properly, it may lead to reduced grinding efficiency and even cause premature wear of the grinding wheel or burns of the workpiece. The accurate adjustment of the grinding wheel position determines the precise position of the grinding point, which is especially important for workpieces that require high-precision processing. By accurately adjusting the grinding wheel position, the precise correspondence between the grinding surface and the workpiece surface can be ensured to achieve high-precision processing requirements.

[0003] During the processing of high-precision surface grinders, the continuous friction between the grinding wheel and the processed product makes the connection between the grinding wheel and the flange and the rotating shaft easily deflected, especially the end of the flange far away from the rotating shaft, which has too little connection with the rotating shaft, and thus easily causes angular deviation. It is not only difficult to find the deviation in time, but also extremely time-consuming and laborious to reinstall the grinding wheel and flange, making it inconvenient to use.

[0004] The existing patent (publication number: CN215547322U) is a high-precision surface grinder grinding wheel angle adjustment mechanism, which is installed by installing an adjustment device inside the end of the grinding arm, and connecting the fixed box in the adjustment device to the flange on the surface of the grinding wheel body, and then adjusting the height of one end of the flange by changing the height of the fixed box, and inserting the measuring block inside the fixed box into the interior of the flange, and monitoring the force of the inner wall of the flange on the measuring block, so as to facilitate the judgment of whether the flange and the grinding wheel body are tilted and the tilt direction, and then adjust it through the fixed box, so that it has the characteristic of facilitating timely adjustment of the grinding wheel angle of the high-precision surface grinder.

[0005] In view of the above problems, existing patents have provided solutions, but most existing grinders have fixed grinding angles and positions during processing, which makes it inconvenient to adjust the grinding angles. When faced with workpieces with different processing requirements, it is necessary to constantly change the clamping position of the workpiece to adapt to the grinding angle and position, resulting in low processing efficiency.

[0006] Therefore, a CNC precision surface grinder with a grinding wheel adjustment mechanism is proposed. Utility Model Content
