DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0021] Example:

[0022] It includes support columns 1 on both sides, and a vertically extending track groove 2 is provided on the support column 1. A lifting frame 3 is slidably matched with the track groove 2, and slide bars are provided on both sides of the lifting frame 3. Side slideways adapted to the slide bars are provided on the side walls of the track groove 2, and the lifting guidance and constraint are achieved by constraining the slide bars through the slideways.

[0023] A motor is installed at the bottom of the support column 1, and a screw rod 4 is provided on the top of the motor for driving the motor to rotate. A nut 5 threadedly connected to the screw rod 4 is passed through the bottom of the lifting frame 3, and the lifting and lowering of the lifting frame 3 can be controlled based on the rotation of the screw rod 4.

[0024] A frame 6 is provided at the top of the lifting frame 3, and a roller 7 is rotatably mounted on the frame 6. The axes of the two rollers 7 are horizontal and parallel. A circular belt is wound between the two rollers 7. The outer surface of the belt is a grinding surface for grinding the template surface. Based on the above structure, the belt is located between the two lifting frames 3. Based on the circular winding of the belt and the rollers 7 at both ends, the belt includes an upper belt 8 and a lower belt 9 based only on the position. One roller 7 is driven by a motor. The specific structure can be that the motor is directly installed on one side of the frame 6, and the output shaft of the motor is connected to the shaft of the roller 7 through a reducer. A pulley can also be installed on the shaft of one of the rollers 7, and the belt is driven by the motor through a belt transmission. This is not limited to the example of this example, and any structure that drives the roller 7 to rotate is acceptable.

[0025] A connecting frame 10 is provided between the frames 6 to connect the two fixedly, and the connecting structure is strengthened by the connecting frame 10 to improve the stability of lifting. An optical axis 11 extending in the same direction as the belt is provided on one side, and the two ends of the optical axis 11 are respectively fixed on the frame 6 on the same side. The optical axis 11 is a circular optical axis 11, and a sliding sleeve 12 is sleeved on the optical axis 11. The sliding sleeve 12 is in clearance with the optical axis 11, and can rotate relative to the optical axis 11 and slide along the length direction of the optical axis 11. A pressure rod 13 is fixed on the upper part of the sliding sleeve 12, and a connecting rod 14 is provided on the pressure rod 13. A hanging hole 15 that is in clearance with the pressure rod 13 is penetrated at the top of the connecting rod 14, and the pressure rod 13 penetrates the hanging hole 15 to achieve sleeve connection with the connecting rod 14, and a threaded hole is provided on the top of the connecting rod 14 to communicate with the hanging hole 15, and a positioning bolt 16 threadedly connected to it is penetrated in the threaded hole, and a slot is provided on the pressure rod 13, and the positioning bolt 16 is movably plugged into the slot.

[0026] A pressure plate 17 is hinged at the bottom end of the connecting rod 14, and a hinge seat 18 hinged to the bottom end of the connecting rod 14 is centrally provided on the top surface of the pressure plate 17. When the positioning bolt 16 is inserted into the slot on the pressure rod 13, the pressure plate 17 is located above the lower belt 9. When the outer end of the pressure rod 13 is pressed downward, the pressure plate 17 can be driven downward and pressed on the inner side of the lower belt 9, and the lower belt 9 is deformed and pressed downward on the surface of the plate. Based on the rapid rotation of the belt, the grinding operation on the fixed position is realized.

[0027] A counterweight rod 19 is provided at one end of the sliding sleeve 12 away from the pressure rod 13, and the end of the counterweight rod 19 is inclined upward. The counterweight rod 19 is equipped with a counterweight block. When the pressure rod 13 is not pressed, it can naturally press down to make the sliding sleeve 12 flip backward, thereby lifting the pressure rod 13 at the other end, so that the pressure plate 17 is away from the lower belt 9 without human intervention.

[0028] A linear track 20 is fixed on the inner side of the support column 1. The length direction of the linear track 20 extends horizontally and is arranged perpendicular to the length direction of the belt. A slider 21 is slidably fitted on the linear track 20. A support plate 22 is provided under the belt. The bottom of the support plate 22 is fixed on the slider 21. The support plate 22 can slide back and forth in the vertical direction relative to the belt based on the guidance of the linear track 20.

[0029] Not limited to this example, electric power can also be added to the forward and backward operations of the pallet 22. For example, a rack is set on the bottom surface of the pallet 22, and a gear with a motor is installed on the support column 1 on one side. The forward and backward sliding of the pallet 22 can be controlled by the meshing of the gear and the rack.

[0030] By using this device, the plate is placed on the support plate 22 and the pressing rod 13 is operated to grind any position on the plate surface. Its advantages include:

[0031] The pressing plate 17 can slide left and right through the optical axis 11, and the plate can be guided to slide forward and backward through the linear track 20. The cooperation of the two can quickly locate any position on the plate surface that needs to be processed.

[0032] By utilizing the lever principle, when the pressing rod 13 is pressed down, a greater pressing force on the board surface can be easily obtained, thereby performing the grinding operation with less effort.

[0033] Based on the pressing plate 17 pressing down the belt, the bottom surface of the continuously rotating belt is in contact and friction with the plate surface, the pressing and grinding force are freely controllable, and the grinding position is also convenient for quick positioning, so that the operation is very efficient and labor-saving.

[0034] The structure that can be raised and lowered relative to the support plate 22 can adapt to plates of different thicknesses.
