[0041] In actual application, the Z-direction adjustment mechanism includes a Z-direction base 14, a lifting seat 15 and an adjustment component. The Z-direction base 14 is arranged on the X-direction base 10. The X-direction base 10 has a lifting channel 16. The lifting seat 15 can be lifted and lowered with the Z-direction base 14. The lower end of the lifting seat 15 passes through the lifting channel 16. The lifting seat 15 has an extension section below the X-direction base 10. The first motor 2 is arranged at the lower end of the extension section. The adjustment component cooperates with the lifting seat 15 to adjust the Z-direction position of the lifting seat 15.

[0042] In this technical solution, the Z-axis adjustment mechanism is used to adjust the movement of the grinding wheel 3 in a direction perpendicular to the plane of the X-axis and Y-axis, and on the other hand, it can accurately control the grinding surface of the grinding wheel 3 to be parallel to the workpiece surface to achieve the purpose of precise grinding.

[0050] In actual application, an adjustment structure is provided at the lower end of the Z-axis adjustment mechanism for adjusting the motor position so that the grinding surface of the grinding wheel 3 is parallel to the surface of the workpiece to be ground. A flushing and lubrication pipe 28 and a grinding surface rounding structure of the grinding wheel 3 are also provided on the three-dimensional adjustment mechanism. One end of the flushing and lubrication pipe 28 is used to connect a flushing and lubricating liquid device, and the other end is provided with a flushing nozzle 29. The liquid spray port of the flushing nozzle 29 is arranged corresponding to the grinding surface of the grinding wheel 3.

[0054] In this technical solution, the drill bit on the grinding surface circular adjustment structure of the grinding wheel 3 is fitted into the grinding surface of the grinding wheel 3, and the first motor 2 is started to rotate the grinding wheel 3. During the rotation of the grinding wheel 3, the X-axis adjustment mechanism or the Y-axis adjustment mechanism is adjusted to move the drill bit along the axial direction of the grinding wheel 3, thereby drilling the grinding surface of the grinding wheel 3 into a standard cylindrical surface.

[0055] In the present technical solution, the grinding surface rounding structure of the grinding wheel 3 includes a dressing fixed seat 30 fixed on the base 1, a dressing adjustment seat 31 whose position can be adjusted with the dressing fixed seat 30, and a dressing head 32 arranged on the dressing adjustment seat 31, and the outer end of the dressing head 32 is a pointed drilling portion.

The longitudinal section of the dressing fixed seat is trapezoidal, and the short upper bottom of the trapezoid faces the grinding wheel 3. The dressing adjustment seat 31 is provided with a long strip-shaped adjustment guide groove 33, and the adjustment guide groove 33 is inclined in the X direction and the Z direction, and is inclined in the direction of the grinding wheel 3. The dressing fixed seat has a recessed guide groove, and the dressing adjustment seat 31 is arranged in the guide groove for guiding the dressing adjustment seat 31.

[0056] When the grinding surface of the grinding wheel 3 is rounded, the X-axis adjustment mechanism and the Y-axis adjustment mechanism are adjusted to make the grinding surface of the grinding wheel 3 close to the pointed drilling part of the dressing head 32, and then the Y-axis base 8 is moved back and forth to make the grinding wheel 3 move back and forth in the Y direction, so that the pointed drilling part of the dressing head 32 acts on various parts of the grinding surface of the grinding wheel 3. Since the pointed drilling part of the dressing head 32 is fixed and the X-axis position of the grinding wheel 3 remains unchanged, it can be adjusted to a regular cylindrical shape under the action of the pointed drilling part of the dressing head 32, so that the grinding wheel 3 with a regular cylindrical grinding surface has a better effect of grinding the workpiece surface.

[0057] In this embodiment, both the X-axis drive 11 and the Y-axis drive 9 are servo motors with reducers. The use of servo motors is conducive to precise control of movement, thereby helping to improve grinding accuracy.
