[0016] A buffer oil hole is arranged on the cylinder sleeve, one end of the buffer oil hole is communicated with the sliding chamber, and the other end of the buffer oil hole is communicated with one end of the hydraulic oil hole close to the outer surface of the cylinder sleeve.

[0017] Preferably, a buffer limit assembly is fixedly provided on the right side of the upper end surface of the first base;

[0018] A limit plate is fixedly provided on the lower end surface of the workbench, and the limit plate is located at the front end of the sliding push rod on the buffer limit assembly at the right position of the upper end surface of the first base, and is symmetrically arranged with the sliding push rod along the X-axis direction;

[0019] A grinding wheel dressing assembly is provided on the upper end surface of the workbench dressing section located on the left side of the workbench.

[0020] Preferably, the wear-resistant positioning pad and the limiting plate are fixed by thread-locking with a locking screw.

[0021] The beneficial effect of the utility model is that a grinding wheel dressing assembly is fixedly arranged on the non-grinding area surfaces at both ends of the surface grinder worktable, and the worktable is operated to move along the X-axis direction. When the worktable moves to the limit position, at this time, the topmost position of the diamond pen on the grinding wheel dressing assembly and the bottommost position of the grinding wheel are located in the same straight line position in the Y-axis direction, and then the grinding wheel is operated to move along the Y-axis and the Z-axis to dress and grind the grinding wheel. The whole operation process is simple and fast, with high work efficiency, and the grinding wheel can be quickly and accurately ground, thereby shortening the processing time of the processed workpiece;

[0022] Furthermore, since a buffer limit assembly is fixedly arranged on the upper end surface of the first base and a limit plate is fixedly arranged on the lower end surface of the workbench, when the workbench moves to a position close to the limit position, the wear-resistant positioning pad on the limit plate contacts with the sliding push rod on the buffer limit assembly. After the limit plate and the buffer limit assembly contact, they continue to move slowly under the support of the elastic force of the support spring. While the limit plate moves slowly, it drives the workbench to move slowly synchronously until it moves to the limit position. In this way, the impact force generated when the workbench moves to the limit position at high speed can be avoided, which may impact the piston cylinder and cause oil leakage or even damage to the piston cylinder, thereby extending the service life of the piston cylinder and ensuring that the surface grinder can operate stably for a long time.

[0023] At the same time, by providing a buffer oil hole on the cylinder sleeve of the piston cylinder, when the workbench moves to a position close to the limit, the front end of the sliding sealing sleeve slides to the inside of the cylinder sleeve, and under the sealing action of the oil sealing ring on the sliding sealing sleeve, the hydraulic oil is sealed in the sliding chamber between the cylinder sleeve, the sliding sealing sleeve and the outer cylinder body of the cylinder. As the piston rod continues to move forward, the hydraulic oil is squeezed into the buffer oil hole, and the hydraulic oil eventually flows back to the hydraulic station along the buffer oil hole. Since the hydraulic oil is incompressible, the flow rate and flow speed of the hydraulic oil flowing from the buffer oil hole are much lower than the flow speed of the hydraulic oil flowing from the hydraulic oil hole, thereby increasing the resistance to the movement of the piston rod and reducing the speed of the piston rod movement, further avoiding the impact force generated when the piston rod moves to the limit position at high speed, causing impact on the components on the piston cylinder, resulting in oil leakage or even damage to the piston cylinder, further extending the service life of the piston cylinder, and ensuring that the surface grinder can operate stably for a long time.

The outer diameter dimension of the front end position of the outer circumference of the sliding sealing sleeve 19 is smaller than the inner diameter dimension of the cylinder sleeve 15 located in the inner part of the sliding chamber 20, and an oil sealing ring 17 is fixedly provided on the outer circumference of the front end position of the outer circumference of the sliding sealing sleeve 19. When the front end position of the sliding sealing sleeve 19 slides into the inside of the cylinder sleeve 15, the outer circumference of the front end position of the sliding sealing sleeve 19 and the inner circumference of the cylinder sleeve 15 are slidingly and sealingly connected via the oil sealing ring 17.

[0048] The cylinder sleeve 15 is provided with a buffer oil hole 14 , one end of which is communicated with the sliding chamber 20 , and the other end of which is communicated with an end of the hydraulic oil hole 16 close to the outer surface of the cylinder sleeve 15 .

[0049] By providing a buffer oil hole 14 on the cylinder sleeve of the piston cylinder, when the workbench 2 moves to a position close to the limit, the front end of the sliding seal sleeve 19 slides to the inside of the cylinder sleeve 15, and the hydraulic oil is sealed in the sliding chamber 20 between the cylinder sleeve 15, the sliding seal sleeve 19, and the outer cylinder body 12 under the sealing effect of the oil seal ring 17 on the sliding seal sleeve 19. As the piston rod 13 continues to move forward, the hydraulic oil is squeezed into the buffer oil hole 14, and the hydraulic oil finally flows back to the hydraulic station along the buffer oil hole 14. The pressurized oil is incompressible, and the flow rate and flow speed of the hydraulic oil flowing from the buffer oil hole 14 are much lower than the flow speed of the hydraulic oil flowing from the hydraulic oil hole 16, thereby increasing the resistance to the movement of the piston rod 13 and reducing the movement speed of the piston rod 13, further avoiding the impact force generated when the piston rod 13 moves to the extreme position at high speed, causing impact on the components on the piston cylinder, causing oil leakage in the piston cylinder, or even damage, further extending the service life of the piston cylinder, and ensuring that the surface grinder can operate stably for a long time.

A grinding wheel dressing assembly 8 is provided on the upper end surface of the workbench dressing section 202 on the left side of the workbench 2.

[0051] By respectively arranging buffer limit assemblies 7 at both ends of the upper end surface of the first base 1, respectively arranging limit plates 11 on the lower end surface of the workbench 2 corresponding to the buffer limit assemblies 7 at both ends of the upper end surface of the first base 1, and arranging grinding wheel dressing assemblies 8 on the upper end surfaces of the workbench dressing sections 202 at both ends of the workbench 2, when one group of the buffer limit assemblies 7, the grinding wheel dressing assemblies 8 or the limit plates 11 fails, the workbench 2 can be moved in the opposite direction and the other group can be used for grinding with the grinding wheel, so as to avoid the grinding wheel not being able to be ground in time due to fault maintenance, delaying the normal processing of the workpiece, and even causing unnecessary economic losses.

[0052] The wear-resistant positioning pad 1101 and the limit plate 11 are threadedly locked and fixed by the locking screw 18. When the wear-resistant positioning pad 1101 and the sliding push rod 703 are in contact for a long time, the surface of the wear-resistant positioning pad 1101 will inevitably be damaged. At this time, you only need to disassemble and assemble the locking screw 18 to quickly replace the wear-resistant positioning pad 1101. The operation is simple and quick.

[0053] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
