Description

Technical Field

[0001] The utility model relates to the technical field of tombstone stone polishing, in particular to a tombstone stone polishing machine which is convenient for turning over. Background Art

[0002] Polishing can make the stone surface smoother and brighter, with stronger light reflecting ability, that is, glossiness, thereby enhancing the visual beauty of the tombstone, and at the same time can effectively protect the stone surface of the tombstone.

[0003] After searching, the patent document with announcement number CN220783368U discloses a stone polishing machine for tombstone processing. The polishing machine places the tombstone stone inside the load-bearing plate, and then rotates the positioning screw. The positioning screw drives the extrusion plate to contact the tombstone stone, making it convenient for users to disassemble and assemble the tombstone stone. Then, the working motor drives the working screw to rotate. The working screw is adapted to the guide block at the bottom of the load-bearing plate, making it convenient for users to adjust the horizontal position of the tombstone stone. Then, under the action of the double-headed screw, the screw cap in contact with the first mounting seat is installed, making it convenient for users to disassemble and assemble the movable plate.

[0023] A tombstone polishing machine that is easy to turn over, such as Figure 1-4 As shown, it includes a support frame 1, the interior of the support frame 1 is provided with a flip hole, support columns 2 are fixed at the four corners of the bottom of the support frame 1, a polishing frame 3 is fixed on the top of the support frame 1, an operating pipe 4 is fixed on the top of the inner wall of the polishing frame 3, and a polishing machine 5 is fixed at the bottom of the operating pipe 4. The operating pipe 4 can drive the polishing machine 5 to move so as to quickly polish the surface of the tombstone stone;

[0024] A one-way drive mechanism is provided on both sides of the top of the support frame 1, and a positioning ring 6 is provided through the one-way drive mechanism. A rotating rod 7 is rotatably passed through both sides of the positioning ring 6. The rod walls of the two rotating rods 7 are rotatably sleeved with a damping sleeve 19. The damping sleeve 19 is fixedly connected to the outer wall of the positioning ring 6. The damping sleeve 7 can damp and position the rotation position of the rotating rod 7 to ensure that the position of the stone is stable after turning over. An electric push rod 8 is fixed on one end of the two rotating rods 7. A splint 9 is fixed on the end of the output shaft of the two electric push rods 8. The outer wall of the positioning ring 6 is provided with a mobile polishing mechanism for driving the positioning ring 6 to move. The electric push rod 8 cooperates with the splint 9 to stably clamp the stone in the positioning ring 6 for stable polishing processing.

[0025] The one-way drive mechanism includes a support ring 10, which is U-shaped and sleeved on the outside of the positioning ring 6. Two symmetrically arranged vertical rods 11 are fixed on both sides of the bottom of the support ring 10. A mounting plate 12 is fixed at the bottom of the vertical rod 11. The mounting plate 12 is fixed to the top of the support frame 1. The mounting plate 12 and the vertical rod 11 effectively support the setting position of the positioning ring 6.

[0026] A plurality of spaced mounting blocks 13 are fixedly provided on the top of the mounting plate 12, and a mounting rod 14 is fixedly passed through the end of the mounting block 13. A ratchet 15 is provided on the rod wall rotation sleeve of the mounting rod 14, and the ratchet 15 rotates with the rod wall of the mounting rod 14 through its internal bearing. The rod wall sleeve of the mounting rod 14 is provided with a torsion spring 16, and the two ends of the torsion spring 16 are respectively fixedly connected to the ratchet 15 and the mounting rod 14. A ratchet 17 is provided on the rod wall fixing sleeve of the rotating rod 7, and the ratchet 15 is matched with the ratchet 17. A limiting rod 18 is provided in contact with the side wall of the ratchet 15, and the limiting rod 18 is fixedly connected to the mounting block 13. The limiting rod 18 contacts and cooperates with the lower end of the outer arc surface of the ratchet 15. The one-way engagement of the ratchet 15 and the ratchet 17 enables the tombstone stone to rotate stably in the positioning ring 6 and turn over when the positioning ring 6 moves back and forth once.

[0027] The mobile polishing mechanism includes a cylinder 20, a fixed plate 21 is fixed to the outer wall of the support frame 1, the cylinder 20 is fixed to the outer wall of the fixed plate 21, and the output shaft passes through the fixed plate 21 and is fixedly connected to the positioning ring 6. The setting of the cylinder 20 enables the tombstone stone to enter the bottom of the polishing machine 5 for stable polishing processing.

[0028] To sum up: before the polishing work is carried out, the positioning ring 6 is located outside the support ring 10, and the tombstone material can be placed in the positioning ring 6, and the two electric push rods 7 drive the clamping plates 9 to move, so that the two clamping plates 9 can effectively clamp the stone material, and then the cylinder 20 is started to push the positioning ring 6 into the support ring 10. During the movement of the positioning ring 6, the ratchet 17 is supported by the torsion of the torsion spring 16 and only contacts the outer arc surface of the multiple ratchet teeth 15. At this time, the ratchet teeth 15 cannot push the ratchet 17, so that the ratchet 17 does not rotate when the positioning ring 6 enters the interior of the support ring 10. At this time, the tombstone material can stably enter the interior of the polishing frame 3 and be quickly polished by the polishing machine 5;

[0029] When the stone needs to be turned over, the cylinder 20 pulls back to move the positioning ring 6 out of the support ring 10. During this process, the ratchet 15 can push the ratchet 17 through the support of the limit rod 18, so that the ratchet 17 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the electric push rod 8 and the splint 9 to rotate under the support of the damping sleeve 19, so that the stone can be stabilized and continue to enter the polishing frame 3 to complete the polishing work.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
