Specific embodiments

[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0021] As Figures 1-3 shown, a surface polishing machine for tombstone processing includes a support housing 9 and a grinding mechanism. Two symmetrically arranged long strip concave-shaped blocks 24 are connected above the support housing 9. Clamping mechanisms are provided on both long strip concave-shaped blocks 24. A rotating shaft 29 is installed on the side of the long strip concave-shaped block 24 by screws. Gears 18 are fixedly sleeved on the surface of the rotating shaft 29. Racks 12 are engaged below the gears 18. A first electric cylinder 1 is provided between one ends of the two racks 12. The housing of the first electric cylinder 1 is installed on the top of the support housing 9 by screws. When performing the flipping operation on the tombstone, the movable end of the first electric cylinder 1 extends to push the two racks 12 to move. When the two racks 12 move, they apply a tangential force to the two gears 18. After the two gears 18 are stressed, they rotate in two bearing seats through the rotating shaft 28. The two rotating shafts 28 drive the two ends of the tombstone to flip synchronously through the two long strip concave-shaped blocks 24 and the four concave-shaped clamping parts 23 to complete the flipping operation of the tombstone. After the flipping is completed, the third electric cylinder 14 can be operated to push the support plate 11 to support the bottom of the tombstone, which improves the stability of the tombstone during processing.

[0022] Two mounting blocks 27 are installed on the top of the support housing 9 by screws. A bearing housing is installed on the top of the mounting block 27 by screws. One end of the rotating shaft 29 is tightly fitted and inserted into the inner ring of the bearing housing.

[0023] Sliding rails 21 are installed at the bottom of the racks 12 by screws. One end of the sliding rail 21 is installed with a movable support rod 20 by screws. The bottom of the movable support rod 20 contacts the top of the support housing 9. The other end of the sliding rail 21 is provided with a support rod 16. The top end of the support rod 16 is installed with a slider 17 by screws. The top end of the slider 17 extends into the chute of the sliding rail 21. The bottom end of the support rod 16 is installed on the top of the support housing 9 by screws. A connecting rod 19 is installed between one ends of the two movable support rods 20 by screws. The side of the connecting rod 19 is connected to the movable end of the first electric cylinder 1 by screws.

[0024] The clamping mechanism includes two ball screws 25 with opposite thread directions. One ends of the two ball screws 25 are welded and fixed. The other ends of the two ball screws 25 are tightly sleeved with bearings. The two bearings are installed in the inner groove of the long strip concave block 24 by screws. Concave clamping parts 23 are installed on the nut surfaces of the two ball screws 25 by screws. One end of one of the ball screws 25 is installed with a handle 22 by screws. When turning over the tombstone, the tombstone is placed on the tops of the two support plates 11 at this time. During operation, first rotate the handle 22 to drive the two ball screws 25 to rotate. The two ball screws 25 drive the two nuts among them to approach each other. At this time, the two nuts drive the two concave clamping parts 23 to move synchronously. When the two concave clamping parts 23 are sleeved on the two corners of the tombstone, continue to rotate the ball screws 25 so that the two concave clamping parts 23 tightly abut against the two corners of the tombstone. Then operate the other group of ball screws 25. When the other two concave clamping parts 23 tightly abut against the other two corners of the tombstone, the fixation of the tombstone position can be completed, which is used to improve the stability of the tombstone during the turning operation. After the turning is completed, the tops of the two support plates 11 can be operated to contact the bottom of the tombstone. The two support plates 11 play a supporting role for the tombstone. At this time, the two groups of ball screws 25 can be rotated in reverse in turn, which is convenient to drive the four concave clamping parts 23 to separate from the four corners of the tombstone, avoiding the concave clamping parts 23 blocking the surface position of the tombstone corners and facilitating the polishing treatment of the tombstone.

[0025] A water blocking frame 8 is installed on the top of the support housing 9 by screws. A sealing rubber pad is bonded to the bottom of the water blocking frame 8. The bottom of the sealing rubber pad contacts the top of the support housing 9. The cooperation of the water blocking frame 8 and the sealing rubber pad is used to prevent the aqueous solution from flowing from the top of the support housing 9 to the ground, avoiding the aqueous solution for cleaning the ground and playing a role in protecting the environment around the device.

[0026] The bottom of the support housing 9 is provided with an opening, and a water storage tank 13 is installed at the opening of the support housing 9 through a plurality of screws. A water outlet pipe is installed through between the side surface of the water storage tank 13 and the side surface of the support housing 9. The water outlet pipe is connected with a stop valve. The water storage tank 13 is used to receive the aqueous solution used during tombstone polishing, avoiding the flow of the aqueous solution to the periphery of the device, and at the same time facilitating the subsequent treatment of the aqueous solution.

[0027] The polishing mechanism includes two second linear motors 7. The two second linear motors 7 are installed on the top of the support housing 9 through screws. The movable ends of the two second linear motors 7 are both installed with second electric cylinders 6 through screws. A first linear motor 5 is installed between the movable ends of the two second electric cylinders 6 through screws. The movable end of the first linear motor 5 is installed with a driving motor 3 through screws. The movable end of the driving motor 3 is installed with a grinding disc 4 through screws. The movable end of the first linear motor 5 is installed with a fixing block 26 through screws. A water pipe 2 is installed through the surface of the fixing block 26. The bottom end of the water pipe 2 extends above the grinding disc 4. A spray head is installed at the bottom end of the water pipe 2. The two second electric cylinders 6 control the grinding disc 4 to move in the vertical direction, and control the grinding disc 4 to move to the surface of the tombstone; the first linear motor 5 controls the grinding disc 4 to move horizontally, and the two second linear motors 7 control the grinding disc 4 to move longitudinally horizontally, thereby controlling the grinding disc 4 to move on the surface of the tombstone, facilitating the polishing treatment of the surface of the tombstone; the driving motor 3 controls the grinding disc 4 to rotate, and the grinding disc 4 polishes the tombstone during rotation.

[0028] A plurality of water inlet openings 10 are provided at the top of the support housing 9. The water inlet openings 10 allow the aqueous solution used during tombstone polishing to fall, facilitating the aqueous solution to fall into the water storage tank 13.

[0029] Two support plates 11 are provided at the top of the support housing 9. A limiting block 28 is installed on the top of the support plate 11 through screws. Two third electric cylinders 14 are installed through the inner top surface of the support housing 9. The movable ends of the two third electric cylinders 14 are respectively installed at the bottom of the two support plates 11 through screws. A support seat 15 is installed between the bottom ends of the two third electric cylinders 14 through screws. Both ends of the support seat 15 are installed on the inner side surface of the support housing 9 through screws. After the tombstone is flipped, the movable ends of the two third electric cylinders 14 can be controlled to extend. The two third electric cylinders 14 push the two support plates 11 to move upward. The tops of the two support plates 11 support the bottom of the tombstone, and the plurality of limiting blocks 28 contact the two symmetrical side surfaces of the tombstone, improving the stability of the tombstone during the polishing process.
