Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of grinding devices, and more particularly, to a grinding device for treating burrs on manhole covers. Background Art

[0002] A manhole cover is a covering used to cover a road or a deep well at home. Its main function is to prevent people or objects from falling, and at the same time, it can also protect the facilities inside the well and keep the environment inside the well from being affected by the outside world. During the production of manhole covers, burrs may appear on the sides of the manhole covers due to improper pressure control or uneven material flow. In order for the manhole cover to fit better with the road surface later, it is necessary to grind the burrs on the manhole cover to make it smooth.

[0003] When grinding the burrs on a circular manhole cover, it is placed on a turntable, and then the grinding piece is moved to fit the manhole cover. By rotating the manhole cover, the burrs on the side of the manhole cover are ground, and the ground debris then falls on the turntable or the workpiece table. If the debris is not cleaned up in time, when a new manhole cover is placed later, the debris is likely to scratch the surface of the manhole cover.

[0004] When cleaning up the debris, a blower is usually installed on the workbench to blow the debris on the turntable or the workbench down. However, after blowing the debris, the debris will fall on the ground, and there is a lack of a collection device on the workbench, making it difficult to synchronously collect the blown-down debris. Further cleaning and collection of the debris on the ground are still required later. Summary of the Invention

The chip collection box 3 is placed opposite to the blower 2 and is used to collect the debris blown by the blower 2. There are two translation components, and the two translation components are respectively arranged at both ends of the support table 1. The chip collection box 3 is arranged on one of the translation components. The adjustment component is arranged on the translation component, and the blower 2 is arranged on the adjustment component. The adjustment component is used to drive the blower 2 to translate so that the chip blowing is complete. The chip blocking component is arranged on the support table 1, and the chip blocking component is adjacent to both sides of the blower 2 and the chip collection box 3, and is used to block the debris from splashing during chip blowing.

[0031] After grinding, when it is necessary to collect the debris generated on the support table 1, such as Figure 2As shown, the blower 2 and the chip collection box 3 are driven to move relative to each other by the translation component. The translation component includes slide rails 4, a first motor 5, a first driving gear 6 and a first rack 7. There are two slide rails 4, and both of the two slide rails 4 are fixedly installed on the side surface of the support platform 1. The chip collection box 3 is slidably installed on the two slide rails 4. The first motor 5 is installed on one of the slide rails 4. The first driving gear 6 is coaxially connected to the output end of the first motor 5. The first rack 7 meshes with the first driving gear 6. One of the first racks 7 is fixedly installed on the side surface of the chip collection box 3. Specifically, when the first motor 5 is started, the output end of the first motor 5 drives the first driving gear 6 to rotate, and the first driving gear 6 drives the first rack 7 to translate, thereby driving the blower 2 and the chip collection box 3 to move relative to each other respectively. Then the chip collection box 3 is moved to the side surface of the support platform 1, and then the blower 2 is started to blow the chips on the support platform 1, as Figure 5 shown. Since a blowing component is installed on the blower 2, the blowing component includes an air outlet pipe 18 and an air outlet hopper 19. The air outlet pipe 18 is connected and installed at the air outlet of the blower 2. There are several air outlet hoppers 19, and several air outlet hoppers 19 are all connected and installed on the side surface of the air outlet pipe 18. The air outlets of several air outlet hoppers 19 face the grinding mechanism. Therefore, the air can be blown out through the air outlet pipe 18 and the multiple air outlet hoppers 19 to completely blow the chips on the support platform 1.

[0032] When blowing, the blower 2 is moved through the adjustment component, so that the blowing is more complete, as Figure 2 shown. The adjustment component includes a support cover 8, a driving screw 9, a second motor 10 and a driving block 11. The support cover 8 is slidably installed on the other two slide rails 4. The other first rack 7 is fixedly installed on the side surface of the support cover 8. The driving screw 9 is rotatably installed in the support cover 8. The second motor 10 is installed on the side surface of the support cover 8, and the output end of the second motor 10 is coaxially connected to the driving screw 9. The driving block 11 is threadedly connected to the driving screw 9, and the blower 2 is installed on the driving block 11. By starting the second motor 10, the output end of the second motor 10 drives the driving screw 9 to rotate in the support cover 8. It should be added that the driving block 11 and the driving screw 9 are in a rolling screw drive, as Figure 7 shown. And a chute is opened on the inner side wall of the support cover 8. The driving block 11 is slidably installed in the chute of the support cover 8 through a slider. Therefore, the driving block 11 can move on the driving screw 9, and then drive the blower 2 to move left and right, so as to completely blow the chips on the support platform 1 into the chip collection box 3. Support rods 23 are fixedly installed on both sides of the driving block 11, and a support ring 24 is fixedly installed on the support rods 23. The air outlet pipe 18 is installed through the support ring 24, and the air outlet pipe 18 can be supported by the support rods 23 and the support ring 24.

[0033] When blowing the chips, the other two sides of the support platform 1 can be blocked by the chip blocking component, as Figure 3As shown in the figure, the chip baffle assembly includes a chip baffle 12, a first electric cylinder 13 and a transmission assembly. Chutes are provided on both sides of the support table 1. There are two chip baffles 12, and the two chip baffles 12 are respectively slidably installed on both sides of the support table 1. The length of the chip baffle 12 is consistent with the length of the support table 1. There are two first electric cylinders 13, and the two first electric cylinders 13 are both installed on both sides of the support table 1. The output ends of the two first electric cylinders 13 are fixedly connected to the bottom end of one of the chip baffles 12. The transmission assembly is arranged on the side of the support table 1 and is used to drive the two chip baffles 12 to move up and down synchronously. The transmission assembly includes a fixed frame 14, a transmission shaft 15, a second rack 16 and a second driving gear 17. The fixed frame 14 is fixedly installed on the side of the support table 1. The transmission shaft 15 is rotatably installed through the fixed frame 14. There are two second racks 16, and the two second racks 16 are respectively fixedly installed on the sides of the two chip baffles 12. There are two second driving gears 17, and the two second driving gears 17 are respectively fixedly installed at both ends of the transmission shaft 15, and the two second driving gears 17 are respectively meshed with the two second racks 16.

[0034] Specifically, when the first electric cylinder 13 is started, the output end of the first electric cylinder 13 drives one of the chip baffles 12 to move up. The chip baffle 12 drives the second rack 16 on its side to move. The second rack 16 drives one of the second driving gears 17 to rotate. The second driving gear 17 drives the transmission shaft 15 to rotate on the fixed frame 14. The transmission shaft 15 drives the other second driving gear 17 to rotate. The second driving gear 17 drives the second rack 16 to move up. The second rack 16 drives the other chip baffle 12 to move up, so as to realize the synchronous upward movement of the two chip baffles 12. And the length of the chip baffle 12 is greater than the width of the support table 1. Therefore, it can block the chips on both sides of the support table 1 and can also block during grinding to prevent the chips from flying out of the support table 1.

[0035] A leak-proof component is installed on the chip collection box 3, such as Figure 4 As shown in the figure, the leak-proof component includes a second electric cylinder 20, a leak-proof plate 21 and a connecting rod 22. There are two second electric cylinders 20, and the two second electric cylinders 20 are respectively installed on both sides of the chip collection box 3.

There are two connecting rods 22, and the two connecting rods 22 are respectively fixedly connected to the output ends of the two second electric cylinders 20. The two connecting rods 22 are fixedly connected to the top end of the leak-proof plate 21. During collection, when the second electric cylinder 20 is started, the output end of the second electric cylinder 20 drives the leak-proof plate 21 to move up. After collection is completed, it drives the leak-proof plate 21 to move down, so as to block the opening of the chip collection box 3, and then move to the position opposite to the support table 1, which is convenient for subsequent cleaning, and the chips will not leak out during the movement.

[0036] Working principle: After grinding is completed, start motor 1 - 5. The output end of motor 1 - 5 drives drive gear 1 - 6 to rotate. Drive gear 1 - 6 drives rack 1 - 7 to translate, thereby driving blower 2 and chip collection box 3 to move relative to each other respectively. Then move chip collection box 3 to the side of support platform 1. Then start blower 2 to blow the chips on support platform 1. Start blower 2. Blower 2 blows the air into air inlet and outlet pipe 18 and several air outlet hoppers 19, making the blowing more comprehensive. And when blowing, motor 2 - 10 can be started. The output end of motor 2 - 10 drives drive screw 9 to rotate in support cover 8. Drive block 11 moves on drive screw 9, and then drives blower 2 to move left and right, blowing the chips on support platform 1 completely into chip collection box 3. Before blowing, start electric cylinder 2 - 20. The output end of electric cylinder 2 - 20 drives leak - proof plate 21 to move up, so that the chips can be blown into chip collection box 3. After blowing, move leak - proof plate 21 down to seal chip collection box 3. Then move chip collection box 3 backward to facilitate subsequent cleaning of the chips in chip collection box 3.
