Description

Technical Field

[0001] This utility model relates to the field of grinding wheel dressing technology, specifically a CNC grinding wheel dressing device for a grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses abrasives to grind the surface of a workpiece. The grinding wheel is an important component of a grinding machine and is commonly used for grinding various mechanical parts. It is a smooth, uniformly thick circular disc with a hole in the center for mounting on a high-speed rotating shaft. During use, the abrasive grains of the grinding wheel will wear and fall off. Due to the uneven hardness of the grinding wheel and the different working conditions of the abrasive grains, the wear and shedding of abrasive grains in different parts of the grinding wheel are different, causing the grinding wheel to lose its shape accuracy. In addition, the abrasive chips generated by the wear of the abrasive grains often get stuck in the pores on the surface of the grinding wheel, causing the surface of the grinding wheel to become blocked and the grinding wheel to lose its cutting ability.

[0003] Currently, traditional grinding wheel dressing relies on experienced technicians using diamond dressing pens to dress the grinding wheels. Because it is a manual operation, it often takes a lot of time to dress the grinding wheels, and manual operation requires multiple measurements and repeated dressing, which is time-consuming and labor-intensive. Moreover, dressing grinding wheels of different specifications requires higher skill levels from the technicians, which is quite inconvenient. Therefore, a CNC grinding wheel dressing device for grinding machines is proposed to solve the problems mentioned above. Utility Model Content

[0007] Furthermore, the fixing component includes a threaded head and a positioning shaft, both of which are fixedly connected to the end of the fixing rod and both penetrate the inner side of the grinding wheel.

[0008] Furthermore, a fixing nut is threaded onto the outer side of the threaded head, and there are two positioning shafts, which are located on the upper and lower sides of the threaded head, respectively.

[0009] Furthermore, the vertical plate is fixedly connected to the top of the base plate, and the drive motor is fixedly installed on the outer wall of the vertical plate.

[0010] Furthermore, a main gear is fixedly connected to the end of the shaft away from the drive motor, and a driven gear is fixedly connected to the outer wall of the rotating sleeve, with the driven gear meshing with the main gear.

[0011] Furthermore, a mounting cover is fixedly connected to the outer wall of the vertical plate, and both the main gear and the driven gear are located inside the mounting cover.

[0013] Furthermore, the guide assembly includes a guide rod and a limiting piece. The guide rod is fixedly connected to the outer wall of the rotating sleeve and passes through the inner side of the mounting plate. The limiting piece is fixedly connected to the outer side of the guide rod.

[0014] Compared with the prior art, this utility model provides a CNC grinding wheel dressing device for a grinding machine, which has the following beneficial effects:

[0015] The CNC grinding wheel dressing device of this grinding machine fixes the grinding wheel to the fixed rod through the cooperation of the threaded head, positioning shaft and fixing nut. The position of the mounting plate is adjusted by the set pneumatic rod. The dressing pen is adjusted to the appropriate position according to the current size of the grinding wheel, so that the dressing pen can keep in contact with the grinding wheel. The drive motor drives the shaft to rotate, which drives the main gear to rotate. Under the transmission of the main gear and the driven gear, the rotating sleeve rotates, which in turn drives the dressing pen to rotate. This allows the dressing pen to efficiently dress the grinding wheel. It solves the problems of often spending a lot of time making grinding wheels, and having to measure and dress them repeatedly by hand, which is time-consuming and labor-intensive. Moreover, dressing grinding wheels of different specifications requires higher operation skills from the technicians and is quite inconvenient. Attached Figure Description
