Description

Technical Field

[0001] This utility model relates to the field of transmission component polishing technology, and in particular to a polishing device for processing transmission components with good dust removal effect. Background Technology

[0002] Transmission components are key parts in mechanical transmission systems used to transmit motion, power, or change the form of motion. They are widely used in various mechanical equipment such as machine tools, automobiles, construction machinery, and robots. Their performance directly affects the efficiency, precision, and reliability of the entire mechanical system. Therefore, when machining transmission components, polishing is necessary to remove burrs and protrusions from the surface, thereby ensuring the accuracy of the transmission components.

[0003] When polishing transmission components, a polishing device is required. The polishing disc is driven by a motor to polish the transmission components. Since dust is generated during the polishing process, a dust removal mechanism is installed on the polishing device to collect the dust and debris generated during polishing, thereby preventing dust and debris from spreading into the external environment.

[0004] However, the suction port of traditional dust removal mechanisms is usually in a fixed position, generally located on the side or above the grinding area. When the grinding position of the transmission component changes, the distance between the suction port of the dust removal mechanism and the dust source may increase. When the distance increases, the suction force of the dust removal structure on the dust source will decrease, and dust will easily spread with the air and be inhaled by the workers. Based on the above problems, this application proposes a polishing device for processing transmission components with good dust removal effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a polishing device for processing transmission components with good dust removal effect, thereby solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A polishing device for processing transmission components with good dust removal effect includes a polishing box. A door is installed on the front side of the polishing box via a hinge. A rotating fixing component is provided on the surface of the polishing box. A lifting component is provided on the surface of the polishing box. A connecting bracket is provided inside the polishing box via the lifting component. A drive motor is fixedly installed on the top of the connecting bracket. A mounting shaft is fixedly installed on the output end of the drive motor. A polishing disc is fixedly installed on the surface of the mounting shaft. A dust collection component is provided on the surface of the polishing box.

[0008] Preferably, the rotating fixing assembly includes a mounting bracket fixedly mounted on the surface of the polishing box. A servo motor is fixedly mounted at the bottom of the mounting bracket. A drive gear is fixedly mounted at the output end of the servo motor. A driven gear is meshed on the surface of the drive gear. A rotating shaft is fixedly mounted inside the driven gear. The rotating shaft is rotatably mounted inside the polishing box. A placement plate is fixedly mounted at the top of the rotating shaft. A transmission component is overlapped on the surface of the placement plate. A fixing nut for fixing the transmission component is threaded on the surface of the placement plate.

[0009] Preferably, the radius of the driving gear is smaller than the radius of the driven gear, and both the driving gear and the driven gear are made of metal.

[0010] Preferably, the lifting assembly includes a hydraulic push rod fixedly installed on the top of the polishing box, a lifting plate fixedly installed at the output end of the hydraulic push rod, a guide rod fixedly installed on the top of the lifting plate, the guide rod being slidably installed inside the polishing box, and a connecting bracket fixedly installed on the top of the lifting plate.

[0011] Preferably, a corrugated protective sleeve is connected between the top of the lifting plate and the upper side wall of the polishing box, the output shaft of the hydraulic push rod is located inside the corrugated protective sleeve, and the corrugated protective sleeve is made of rubber.

[0012] Preferably, the dust collection assembly includes a collection box and a dust collection fan fixedly installed on the top of the polishing box. The air inlet of the dust collection fan is connected to the collection box. A filter screen is fixedly installed inside the collection box. A dust inlet pipe is fixedly installed on the right side of the collection box. A metal corrugated pipe is fixedly installed at the bottom of the dust inlet pipe. A connecting pipe is fixedly installed at the bottom of the metal corrugated pipe. An annular pipe is fixedly installed at the bottom of the connecting pipe.

[0013] Preferably, the number of vacuum tubes is several, and the several vacuum tubes are distributed in a circular array.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the polishing device for processing transmission parts with good dust removal effect has a lifting component that drives the drive motor to move through the mounting bracket, so that the mounting shaft drives the polishing disc to contact the transmission part. During the movement of the lifting component, the dust suction pipe in the collection component will move, so that the dust suction pipe always maintains a suitable distance from the transmission part. This avoids the situation where the distance between the dust suction pipe and the dust source increases, resulting in a decrease in the suction power of the dust removal structure for the dust source. It also avoids the situation where dust is not completely collected and diffuses with the air, and is inhaled by the workers. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example: Refer to Figure 1-4A polishing device for processing transmission parts with good dust removal effect includes a polishing box 1. A door 2 is hinged to the front of the polishing box 1. A rotating fixing assembly and a lifting assembly are provided on the surface of the polishing box 1. A connecting bracket 13 is provided inside the polishing box 1 via the lifting assembly. A drive motor 14 is fixedly mounted on the top of the connecting bracket 13. A mounting shaft 15 is fixedly mounted on the output end of the drive motor 14. A polishing disc 16 is fixedly mounted on the surface of the mounting shaft 15. A dust collection assembly is provided on the surface of the polishing box 1. The lifting assembly includes a hydraulic push rod 11 fixedly mounted on the top of the polishing box 1. A lifting plate 12 is fixedly mounted on the output end of the hydraulic push rod 11. A guide rod 26 is fixedly installed at the top of the polishing box 1. The guide rod 26 is slidably installed inside the polishing box 1. The connecting bracket 13 is fixedly installed on the top of the lifting plate 12. The dust collection assembly includes a collection box 17 and a dust collection fan 19 fixedly installed at the top of the polishing box 1. The air inlet of the dust collection fan 19 is connected to the collection box 17. A filter screen 18 is fixedly installed inside the collection box 17. A dust inlet pipe 20 is fixedly installed on the right side of the collection box 17. A metal corrugated pipe 21 is fixedly installed at the bottom of the dust inlet pipe 20. A connecting pipe 22 is fixedly installed at the bottom of the metal corrugated pipe 21. An annular pipe 23 is fixedly installed at the bottom of the connecting pipe 22. A dust collection pipe 24 is fixedly installed at the bottom of the annular pipe 23. There are several suction pipes 24 arranged in a circular array. A movable plate 25 is fixedly mounted on the surface of each suction pipe 24. The movable plate 25 is fixedly installed on the top of the lifting plate 12. The drive motor 14 drives the polishing disc 16 to rotate via the mounting shaft 15. The hydraulic push rod 11 moves the connecting bracket 13 and the movable plate 25 via the lifting plate 12, causing the drive motor 14 to drive the polishing disc 16 to contact the transmission component 9 via the mounting shaft 15, polishing the transmission component 9. This causes the movable plate 25 to move the suction pipes 24 downwards, causing the annular pipe 23 to stretch the metal corrugated pipe 21 via the connecting pipe 22, positioning the suction pipes 24 at the top of the transmission component 9. Above, the dust collector 19 is activated, causing the dust collection pipe 24 to collect the dust and debris generated during polishing. The collected dust and debris enter the collection box 17 through the annular pipe 23, connecting pipe 22, metal corrugated pipe 21, and dust inlet pipe 20. The filter screen 18 blocks the incoming dust and debris, keeping them inside the collection box 17. This ensures that the dust collection pipe 24 maintains a suitable distance from the dust source, preventing the distance from the dust source from becoming too large, which would weaken the suction of the dust collection pipe 24 and cause it to not be completely collected, resulting in the dust spreading in the external environment and being inhaled by the staff.

[0022] Specifically, the rotating fixing assembly includes a mounting bracket 3 fixedly installed on the surface of the polishing box 1. A servo motor 4 is fixedly installed at the bottom of the mounting bracket 3. A drive gear 5 is fixedly installed at the output end of the servo motor 4. A driven gear 6 is meshed on the surface of the drive gear 5. The radius of the drive gear 5 is smaller than the radius of the driven gear 6. Both the drive gear 5 and the driven gear 6 are made of metal. A rotating shaft 7 is fixedly installed inside the driven gear 6. The rotating shaft 7 is rotatably installed inside the polishing box 1. A placement plate 8 is fixedly installed at the top of the rotating shaft 7. A transmission component 9 is overlapped on the surface of the placement plate 8. A fixing nut 10 for fixing the transmission component 9 is threaded on the surface of the placement plate 8. The transmission component 9 to be polished is placed on the top of the placement plate 8, and the fixing nut 10 is tightened on the surface of the placement plate 8 to fix the transmission component 9. Then, the servo motor 4 drives the drive gear 5 to rotate, which causes the rotating shaft 7 to rotate the placement plate 8. The placement plate 8, in conjunction with the fixing nut 10, drives the transmission component 9 to rotate, thereby polishing different positions of the transmission component 9.

[0023] Specifically, a corrugated protective sleeve is connected between the top of the lifting plate 12 and the upper side wall of the polishing box 1. The output shaft of the hydraulic push rod 11 is located inside the corrugated protective sleeve. The corrugated protective sleeve is made of rubber, which facilitates the protection of the hydraulic push rod 11 and prevents the hydraulic push rod 11 from being damaged by contact with dust.

[0024] In use: The drive motor 14 drives the mounting shaft 15 to rotate, which in turn drives the polishing disc 16 to rotate. Meanwhile, the hydraulic push rod 11 drives the lifting plate 12 downwards, causing the lifting plate 12 to slide along the guide rod 26 inside the polishing chamber 1. This allows the lifting plate 12 to drive the drive motor 14 downwards via the connecting bracket 13, causing the drive motor 14 to contact the polishing disc 16 with the transmission component 9 via the mounting shaft 15. The polishing disc 16 then polishes the transmission component 9. As the lifting plate 12 moves downwards, it also drives the moving plate 25 downwards, which in turn drives the suction pipe. 24 moves downwards, and the suction pipe 24 drives the connecting pipe 22 to move downwards through the annular pipe 23, so that the connecting pipe 22 stretches the metal corrugated pipe 21, so that the suction pipe 24 is above the transmission component 9, and the suction fan 19 is started, so that the suction pipe 24 collects the dust and debris generated by polishing. The collected dust and debris enter the interior of the connecting pipe 22 through the annular pipe 23, and then enter the interior of the metal corrugated pipe 21 through the connecting pipe 22. Subsequently, it enters the interior of the collection box 17 through the dust inlet pipe 20, and the filter screen 18 blocks the dust and debris that enters, so that the dust and debris remain inside the collection box 17.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
