[0002] Robots have been widely used in industry, especially in the field of precision machining. Robotic grinding, polishing, and deburring have become key means to improve production efficiency, ensure product quality, and reduce labor costs. However, the process of robotic grinding generates a large amount of dust and debris, which not only affects the grinding quality but also may cause damage to the robot and the operator. In addition, traditional robotic grinding devices often require human assistance, and dust and debris are inevitably generated during the grinding process. If people are in the vicinity of the device for a long time, it can easily endanger their health. In addition, during the grinding process, the tool and the object are prone to high temperature and even fragments will fly out after breaking, posing a significant safety hazard. Dust and debris in the air can also pollute the environment. If the debris and dust generated during the grinding process can be collected and recycled, it can not only reduce production costs, but also avoid environmental pollution, protect personal safety and reduce potential risks. Therefore, it is necessary to design an auxiliary device that can assist robots in grinding operations and recycle the dust and debris generated by grinding, protecting personnel safety and reducing losses. Utility Model Content

[0003] In response to the above technical problems, the utility model provides an auxiliary device that can assist the robot in performing grinding operations and recycle the dust and debris generated by grinding, thereby protecting personnel safety and reducing losses.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3The auxiliary grinding device for an industrial robot shown in the figure includes a bottom box 1 and a dust removal box 2. The dust removal box 2 is fixedly connected to the top right side of the bottom box 1. In order to enable the chuck 6 to clamp the workpiece to be polished, a first screw 3 is rotatably connected to the left side of the bottom box 1. The two ends of the first screw 3 are rotatably connected to the inner wall of the bottom box 1 through bearings. In order to adapt to the size of different workpieces to be polished, electric cylinders 4 are symmetrically slidably connected to the two sides of the first screw 3 through threaded blocks. The electric cylinder 4 drives the clamping seat 5 to move up and down, which facilitates the rotation of the workpiece to be polished, so that the output end of the electric cylinder 4 extends through the top of the bottom box 1. The wall is fixedly connected with a card seat 5. In order to enable the workpiece to rotate autonomously, a chuck 6 is rotatably connected to the card seat 5. A first motor 7 is fixedly connected to the card seat 5. The chuck 6 is driven by the first motor 7. In order to collect the water coming out of the nozzle 13 for reuse, a water collecting tank 22 is provided at the bottom of the bottom box 1. In order to remove the dust and debris generated during grinding, a dust suction nozzle 8 is fixedly connected to the right side of the electric cylinder 4 at the top of the bottom box 1. The output end of the dust suction nozzle 8 is fixedly connected to a dust suction pipe 9 that runs through the side wall of the dust removal box 2. In order to ensure sufficient suction, the dust and debris generated during grinding are removed. The dust is collected into the dust collecting box 2, and a negative pressure fan 10 is fixedly connected to the dust suction pipe 9. The output end of the dust suction pipe 9 is connected to the left side of the top of the dust collecting tank 11. The dust collecting tank 11 is set without a cover to prevent the internal pressure of the dust collecting tank 11 from being too high. In order to filter the moisture sucked into the dust collecting tank 11 into the water collecting tank 22 below, the bottom of the dust collecting tank 11 passes through the bottom wall of the dust removal box 2. In order to collect the water above into the water collecting tank 22, the top wall of the bottom box 1 is connected to the top of the water collecting tank 22. In order to enable the nozzle 13 to move left and right with the grinding tool of the robot, Two symmetrically arranged support frames 12 are fixedly connected to the same side of the dust removal box 2, and a second screw 16 is rotatably connected between the two opposite support frames 12. The second screw 16 is fixedly connected to the nozzle 13 through a slider. In order to ensure that the hose will not get tangled when the nozzle 13 moves left and right, a hose 14 is fixedly connected to the input end of the nozzle 13, and a coiler 17 is fixedly connected to the top of the dust removal box 2. The other end of the hose 14 passes through the limit ring and is wound around the coiler 17. The coiler 17 is a spring rewinding coiler, which can tighten the hose 14.

[0018] In order to control the rotation of the first screw 3 to make the chuck 6 move relative or oppositely, and thus to clamp and release the workpiece, the first screw 3 is set with opposite rotation directions of the threads on both sides. In order to provide power, the first screw 3 is driven by the second motor 20 and the second screw 16 is driven by the third motor 21.

[0019] In order to collect the waste water used during melting, a water collection port 19 is opened on the top of one side of the bottom box 1. The water collection port 19 is connected to the water collection box 22 through a channel. In order to filter out dust and impurities and prevent them from entering the water collection box 22, a filter net is provided at the water collection port 19.

[0020] In order to separate the moisture sucked into the dust collecting box 11 from the dust and debris, a filter cloth layer 18 is detachably connected to the inner wall and the bottom of the dust collecting tank 11. In order to facilitate the cleaning of the filter cloth layer 18, a box door is opened on one side of the dust collecting box 2. In order to avoid excessive pressure in the dust collecting box 2, an air outlet is opened at the top of the dust collecting box 2.

[0021] In order to facilitate the movement of the entire device, a universal wheel 15 is fixedly connected to the bottom of the bottom box 1.

[0022] The specific working process of this utility model is as follows:

[0023] When it is necessary to grind a workpiece, first adjust the electric cylinder 4 according to the size of the workpiece so that the chuck 6 is at a suitable height, and place the workpiece between the two chucks 6. At this time, start the second motor 20 to clamp the workpiece tightly between the two chucks 6. Then push the device to the front of the industrial robot so that the robot can grind. When grinding begins, turn on the negative pressure fan 10 to suck the dust and debris generated by grinding into the dust box 11 through the suction nozzle 8. The dust and debris sucked into the dust box 11 adhere to the filter cloth layer 18. When the temperature of the workpiece being ground or the grinding tool is too high, the hose 1 is turned on. 4 is filled with water, which flows from the nozzle 13 onto the workpiece being polished. Used wastewater flows from the water collection port 19 into the water collection box 22. The water absorbed into the dust box 11 is filtered by the bottom filter cloth layer 18 and flows into the water collection box 22. By controlling the forward and reverse rotation of the third motor 21, the nozzle 13 sprays water at different locations on the workpiece, improving the polishing quality of the workpiece. By providing a hose 14 and a coiler 17, it is possible to ensure that the hose 14 follows the left and right movement of the nozzle 13 without tangling. After dust and debris have been collected in the dust box 11 for a period of time, the box door can be opened to remove the filter cloth layer 18 and clean it. Performing industrial robot-assisted polishing according to the above steps can reduce manual labor intensity, local hazards, protect the health of operators, and recycle dust and debris to avoid air pollution and damage to the equipment, thereby improving the polishing quality.
