The movable end of the X-axis moving component 11 is fixedly connected to the support plate 12. The support plate 12 is fixedly connected to the fixed end of the Y-axis moving component 13. The movable end of the Y-axis moving component 13 is fixedly connected to the fixing frame 14. The fixing frame 14 is fixedly connected to the housing of the first electric push rod 15. A connecting block 16 is fixed to the telescopic rod end of the first electric push rod 15. A second motor 17 is fixedly installed on one side of the connecting block 16. One end of the connecting block 16 is rotatably connected to a bolt 20. One end of the bolt 20 is fixedly connected to the output shaft of the second motor 17. The bolt 20 can pass through the grinding wheel 18. The bolt 20 is screwed to a nut 19. The nut 19 is used to fix the grinding wheel 18.

[0015] In this embodiment, the positioning block 23 on one side of the tabletop 1 and the positioning wheel 21 on the other side cooperate. The positioning wheel 21 is driven to extend and retract by the second electric push rod 22, which can apply pressure to the marble and fix it on the tabletop 1. The position adjustment component can adjust the horizontal or vertical position of the positioning wheel 21 to adapt to marbles of different sizes. The X-axis moving component and the Y-axis moving component cooperate with the first electric push rod 15 to drive the grinding wheel 18 to move in three-dimensional space (X and Y axes translation, Z axis extension and retraction via the electric push rod). The second motor 17 fixes the grinding wheel 18 with bolts 20 and nuts 19 and drives it to rotate to achieve grinding of the marble edge. The positioning block and the positioning wheel 21 form a bidirectional fixing structure to ensure that the marble does not shift during grinding. The X-axis moving component 11 and the Y-axis moving component 13 cooperate with the electric push rod to allow the grinding wheel 18 to cover different positions of the marble edge. The electric push rod can adjust the downward pressure of the grinding wheel 18 to control the grinding depth.

One end of the screw 6 is fixedly connected to the output shaft of the first motor, and the screw 6 is screwed to the slider 8. The other end of the support member is slidably connected to the guide shaft 4, and the guide shaft 4 is fixed to the bracket 2. The upper side of the support member is fixedly connected to the fixed end of the vertical movement assembly 9, and the movable end of the vertical movement assembly 9 is fixedly connected to the connecting frame 10.

[0017] In this embodiment, the first motor drives the screw 6 to rotate, and the screw 6 is screwed to the slider 8, so that the slider 8 slides laterally in the groove of the straight groove rod 7; the guide shaft 4 slides with the support to ensure the stability of the slider 8's movement and realize the precise adjustment of the position of the positioning wheel 21, which is suitable for the positioning needs of marble of different specifications. The movable end of the vertical moving component 9 is connected to the connecting frame 10, which can drive the positioning wheel 21 to move up and down. In conjunction with the lateral adjustment, the two-dimensional position adjustment of the positioning wheel 21 in the plane is realized. Through the transmission of the motor-driven screw 6, the guide shaft 4 cooperates with the straight groove rod 7 to prevent the slider 8 from deviating when moving.

[0018] The vertical moving component 9, the X-axis moving component 11, and the Y-axis moving component 13 are all connected by a drive component. The drive component includes a second screw 24, a moving block 25, a track bracket 26, and a stepper motor 27.

The track bracket 26 of the vertical moving component 9 is fixedly connected to the support member.

[0019] In this embodiment, the stepper motors 27 of the vertical moving component 9, the X-axis moving component, and the Y-axis moving component can drive the screw 6 to rotate. The moving block 25 is screwed to the screw 6 and slides along the track bracket 26, thereby driving the movable ends of each component to move. The track bracket 26 of the X-axis moving component is fixed on the bracket 2 and controls the lateral movement of the grinding wheel 18.

According to the grinding process requirements, the operating parameters of the stepper motor 27 are set through the control system, including the movement paths and speeds of the X-axis moving component, the Y-axis moving component, and the vertical moving component 9, as well as the rotational speed of the second motor 17 (the driving motor for the grinding wheel 18); at the same time, the extension and retraction of the first electric push rod 15 are set to control the downward pressure and grinding depth of the grinding wheel 18 (the control system setting of the motor parameters and the extension and retraction of the first electric push rod 15 are existing technologies, and their principles will not be elaborated here). Start the equipment, and the X-axis moving component, Y-axis moving component, and first electric push rod 15 work together to drive the grinding wheel 18 to move along the edge of the marble along a preset path; the second motor 17 drives the grinding wheel 18 to rotate at high speed to grind the marble edge. After grinding is completed, control the grinding wheel 18, Y-axis moving component 13, and X-axis moving component 11 to stop working, control the second electric push rod 22 to retract the positioning wheel 21, and then take out the processed marble.
