Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a polishing device for producing excavator oil pipe joints. Background Technology

[0002] Excavator hydraulic pipe joints are key components connecting hydraulic pipes in the excavator's hydraulic system. They come in various types and have different functions, directly affecting the sealing performance, reliability, and working efficiency of the hydraulic system.

[0003] Existing polishing devices for excavator oil pipe joint production generate a large amount of dust during the polishing process, which not only pollutes the air but also harms human health. Furthermore, the contact area between the polishing device and the surface of the excavator oil pipe joint generates high temperatures due to prolonged high-speed friction, which can damage both the polishing device and the oil pipe joint. Therefore, it is necessary to provide a polishing device for excavator oil pipe joint production to solve the above-mentioned technical problems. Summary of the Invention

[0004] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, a polishing device for excavator oil pipe joint production is proposed to solve the problems that grinding devices generate a large amount of dust during the polishing process, which not only pollutes the air but also harms human health. Furthermore, the contact area between the polishing device and the surface of the excavator oil pipe joint generates high temperatures due to long-term high-speed friction, which can damage both the polishing device and the oil pipe joint.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a polishing device for the production of excavator oil pipe joints, including a polishing table and a support frame fixedly installed on the top of the polishing table. Three abrasive belt wheels are rotatably installed on the side wall of the support frame via a first rotating shaft. The three abrasive belt wheels are arranged in a triangular distribution, and an abrasive belt for polishing the excavator oil pipe joint is sleeved on the outer wall of the three abrasive belt wheels. A protective box is detachably installed on the outer wall of the support frame, outside one of the abrasive belt wheels. The outer wall of the protective box is provided with a dust collection device for the polishing process and simultaneously blows air onto the surface of the abrasive belt to accelerate the airflow speed on the surface of the abrasive belt.

[0006] Furthermore, a servo motor is fixedly installed on the side wall of the support frame, and the output shaft of the servo motor is fixedly connected to the shaft of one of the sanding belt wheels.

[0007] Furthermore, the dust collection mechanism includes a cylinder fixedly mounted on the outer wall of the protective box, an air filter box fixedly mounted on the side wall of the cylinder, and an air inlet connected to the inside of the air filter box on the side wall of the cylinder. An impeller is rotatably mounted inside the cylinder via a second rotating shaft, one end of which rotatably passes through the cylinder and the air filter box and is fixedly connected to one of the first rotating shafts.

[0008] Furthermore, a first pipe connected to the interior is fixedly installed on the outer wall of the air filter box, and a dust suction nozzle is fixedly installed at one end of the first pipe. The dust suction nozzle is fixedly installed on the front of the protective box, and the bottom of the dust suction nozzle is the dust suction port.

[0009] Furthermore, a second pipe fitting is fixedly installed at the top of the cylinder and communicates with its interior. An air nozzle is fixedly installed at one end of the second pipe fitting, and the air nozzle is fixedly installed at the top of the inner cavity of the protective box.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model has the following beneficial effects: By setting up a dust collection mechanism, since the impeller in the dust collection mechanism is connected to one of the sanding belt wheels, it can use part of the power of the sanding belt wheel to synchronously drive the impeller to rotate. When the impeller rotates, it can generate a suction force at the bottom of the dust collection nozzle, so that the powder generated during sanding belt polishing is sucked into the dust collection nozzle and enters the air filter box through the first pipe for filtration. The filtered clean air can then be blown onto the surface of the sanding belt through the air nozzle, thereby reducing the temperature of the sanding belt caused by friction, avoiding the sanding belt from wearing out due to high temperature, and achieving the effect of extending the service life of the sanding belt.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] A polishing device for producing excavator oil pipe joints includes a polishing table 1 and a support frame 2 fixedly mounted on the top of the polishing table 1. Three abrasive belt wheels 3 are rotatably mounted on the side wall of the support frame 2 via a first rotating shaft. The three abrasive belt wheels 3 are arranged in a triangular pattern, and an abrasive belt 4 for polishing the excavator oil pipe joint is sleeved on the outer wall of the three abrasive belt wheels 3. A protective box 5 is detachably mounted on the outer wall of the support frame 2, outside one of the abrasive belt wheels 3. The outer wall of the protective box 5 is provided with a function to collect dust generated during the polishing process and simultaneously blow air onto the surface of the abrasive belt 4 to accelerate the airflow speed on the surface of the abrasive belt 4.

[0015] In this embodiment, a servo motor 7 is fixedly installed on the side wall of the support frame 2, and the output shaft of the servo motor 7 is fixedly connected to the rotating shaft of one of the sanding belt wheels 3.

[0016] In this embodiment, the dust collection mechanism 6 includes a cylindrical body 61 fixedly mounted on the outer wall of the protective box 5. An air filter box 62 is fixedly mounted on the side wall of the cylindrical body 61, and an air inlet 63 communicating with the inside of the air filter box 62 is opened on the side wall of the cylindrical body 61. An impeller 64 is rotatably mounted inside the cylindrical body 61 via a second rotating shaft. One end of the second rotating shaft rotatably passes through the cylindrical body 61 and the air filter box 62 and is fixedly connected to one of the first rotating shafts.

[0017] In this embodiment, a first pipe 65 communicating with the interior is fixedly installed on the outer wall of the air filter box 62. A dust suction nozzle 66 is fixedly installed at one end of the first pipe 65. The dust suction nozzle 66 is fixedly installed on the front of the protective box 5, and the bottom of the dust suction nozzle 66 is the dust suction port.

[0018] In this embodiment, a second pipe 67 connected to the inside of the cylinder 61 is fixedly provided on the top of the cylinder 61. An air nozzle 68 is fixedly provided at one end of the second pipe 67. The air nozzle 68 is fixedly provided at the top of the inner cavity of the protective box 5.

[0019] Working principle: During use, the servo motor 7 drives one of the sanding belt wheels 3 to rotate. Since multiple sanding belt wheels 3 are fitted with the same sanding belt 4, they rotate synchronously due to friction. The operator can hold the polished excavator oil pipe connector close to the sanding belt 4 in front for grinding and polishing. Since the impeller 64 is connected to one of the sanding belt wheels 3 through the second rotating shaft, the impeller 64 and the sanding belt wheel 3 can rotate synchronously. When the impeller 64 rotates, it can draw air into the cylinder 61. The bottom of the dust suction nozzle 66 generates negative pressure. The dust generated by polishing enters the air filter box 62 through the dust suction nozzle 66 and the first pipe 65. Then, the air enters the cylinder 61 through the air inlet 63. After filtration, the air enters the air nozzle 68 through the second pipe 67 and blows onto the surface of the sanding belt 4. The blown-out air is discharged through the bottom of the protective box 5.
