Description

Technical Field

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4 As shown, a marble drilling processing device includes a worktable 1. Clamping plates 2 are slidably connected to both sides of the top of the worktable 1. Pressure plates 3 are slidably connected to the inner sides of both clamping plates 2. A movable frame 4 is mounted on the top of the worktable 1 and outside the two clamping plates 2 via a self-locking slide rail. A drilling assembly is located at the bottom of the movable frame 4. A transmission assembly is located on the top of the worktable 1. The drilling assembly includes an electric telescopic rod 5. A lifting frame 6 is fixedly connected to the output end of the electric telescopic rod 5. A pressure block 22 is located at the bottom of the lifting frame 6. A through groove 7 is opened inside the pressure block 22, and a drill bit 8 is located in the through groove 7. Corrugated pipes 9 are fixedly connected to both sides of the through groove 7. The transmission assembly includes a bidirectional lead screw 10 and a linkage unit. The bidirectional lead screw 10 is rotatably connected to the lower interior of the worktable 1. A first motor 11 is fixedly connected to the outer side of the worktable 1 via a mounting plate. The output end of the first motor 11 extends into the interior of the worktable 1 and is fixedly connected to the bidirectional lead screw 10. The bottom of the clamping plate 2 is connected to the outer sides of the bidirectional screw 10 via a screw nut pair. The pressure plate 3 can be raised and lowered by a linkage unit. The linkage unit includes a first screw 12, which is rotatably connected to the inside of the two clamping plates 2. The two pressure plates 3 are connected to the outside of the corresponding first screw 12 via a screw nut pair. The bottom of the first screw 12 extends into the lower part of the clamping plate 2 and is fixedly connected to a gear 13. The inside sides of the worktable 1 are fixedly connected to racks 14. The two gears 13 mesh with the corresponding racks 14. The transmission assembly also includes a second screw 15, which is rotatably connected to the inside of the movable frame 4. The outer side of the movable frame 4 is fixedly connected to a second motor 16 via a mounting plate. The output end of the second motor 16 extends into the inside of the movable frame 4 and is fixedly connected to the second screw 15. The top of the electric telescopic rod 5 is fixedly connected to a threaded block, which is connected to the second screw 15 via a screw nut pair.

[0027] During operation, the marble slab to be processed is first placed on top of the support pad 24. Then, the first motor 11 is started, driving the double-acting lead screw 10 to rotate. The double-acting lead screw 10 then drives the two clamping plates 2 to move inward through the lead screw nut pair until the marble slab is clamped. During the movement of the two clamping plates 2, the gear 13 can drive the first lead screw 12 to rotate through the meshing relationship between it and the corresponding rack 14. The first lead screw 12 can then drive the corresponding pressure plate 3 to move downward through the lead screw nut pair until the marble slab inside the two clamping plates 2 is pressed tightly. The cooperation between the two clamping plates 2 and the two pressure plates 3 can clamp the marble slab while providing a pressing force from top to bottom, effectively improving the stability of the subsequent drilling process and avoiding the problem of the marble slab sliding and shifting due to vibration during drilling, which would lead to drilling failure. This improves drilling accuracy. The drilling process is as follows: The moving frame 4 is pushed to the designated position via a self-locking slide rail (this is known prior art and will not be elaborated upon). Then, the second motor 16 is started, driving the second lead screw 15 to rotate. This causes the second lead screw 15 to move the electric telescopic rod 5 and the lifting frame 6 via the lead screw nut pair. This, in turn, moves the drill bit 8 to the designated position via the lifting frame 6 and the fixed cover. The electric telescopic rod 5 is then started, causing the lifting frame 6 and the pressure block 22 to descend. After contacting the marble slab, they continue to descend, pushing the slide rod 20 to retract into the fixed column 19 until the drill bit 8 reaches the drilling location. At this point, the third motor 17 is started to begin drilling, and the suction fan 18 is activated. Dust generated during drilling can be drawn to the suction fan 18 by the corrugated pipe 9, preventing dust from flying everywhere and polluting the air, or even being inhaled by workers and threatening their health. This effectively improves the dustproof effect of the device.

[0028] The bottom of the lifting frame 6 is fixedly connected to the third motor 17 via a fixed cover. The drill bit 8 is rotatably connected to the bottom of the fixed cover. The output end of the third motor 17 is fixedly connected to the drill bit 8. The inside of the lifting frame 6 is equipped with a suction fan 18. The tops of the two corrugated pipes 9 extend into the inside of the lifting frame 6 and are fixedly connected to the suction fan 18. The threads of the two first lead screws 12 are opposite. Buffer pads 23 are fixedly connected to both sides of the bottom of the pressure block 22. A support pad 24 is fixedly connected to the top of the worktable 1.

[0029] The above technical solution, through the combination of buffer pad 23 and support pad 24, can effectively improve the buffering performance and prevent the marble slab from cracking during the drilling process.

[0030] Example 2

[0031] Please see Figure 5As shown in the first embodiment, as another implementation of this utility model, the bottom two sides of the lifting frame 6 are fixedly connected with sliding rods 20, and the top two sides of the pressure block 22 are fixedly connected with fixing columns 19. The bottom of the two sliding rods 20 is slidably connected to the inside of the corresponding fixing columns 19, and a spring 21 is provided inside the fixing column 19 and at the bottom of the sliding rod 20.

[0032] During operation, before drilling, the pressure block 22 is used to press the area around the drilled hole of the marble slab. With the adaptive elastic force of the spring 21, the pressure block 22 can always be pressed tightly against the surface of the marble slab, which can greatly reduce the vibration intensity around the drilled hole of the marble slab, thereby effectively avoiding the problem of cracks in the marble slab caused by excessive drilling vibration.

[0033] The working principle is as follows: First, the marble slab to be processed is placed on top of the support pad 24. Then, the first motor 11 is started, driving the double-acting lead screw 10 to rotate. The double-acting lead screw 10 then drives the two clamping plates 2 to move inward through the lead screw nut pair until the marble slab is clamped. During the movement of the two clamping plates 2, the gear 13 can drive the first lead screw 12 to rotate through the meshing relationship with the corresponding rack 14. The first lead screw 12 can then drive the corresponding pressure plate 3 to move downward through the lead screw nut pair until the marble slab inside the two clamping plates 2 is pressed. Through the cooperation between the two clamping plates 2 and the two pressure plates 3, the marble slab is clamped while a pressing force is provided from top to bottom, which effectively improves the stability of the subsequent drilling process and avoids the problem of the marble slab sliding and shifting due to vibration during the drilling process, thus preventing drilling failure. This improves the drilling accuracy and drilling effect. Then, the moving frame 4 is pushed to the designated position through the self-locking slide rail (this is known prior art and will not be described in detail). The second motor 16 is then started, driving the second lead screw 15 to rotate. This causes the second lead screw 15 to move the electric telescopic rod 5 and the lifting frame 6 via the lead screw nut pair. The lifting frame 6 and the fixed cover then move the drill bit 8 to the designated position. The electric telescopic rod 5 is then started, causing the lifting frame 6 and the pressure block 22 to descend. After contacting the marble slab, the rod continues to descend, pushing the slide rod 20 to retract into the fixed column 19 until the drill bit 8 reaches the drilling point. At this point, the third motor 17 is started to begin drilling, and the suction fan 18 is activated. Dust generated during drilling is drawn to the suction fan 18 by the corrugated pipe 9, preventing dust from flying everywhere and polluting the air or being inhaled by workers, thus effectively improving the dustproof effect of the device. The buffer pad 23, in conjunction with the support pad 24, effectively enhances the buffering performance, preventing cracks in the marble slab during drilling.
