Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and specifically discloses a polishing device for automotive parts processing. Background Technology

[0002] Automotive parts are the various units that make up a car and the various accessories that serve the vehicle. They cover multiple areas such as the engine system, chassis system, braking system, and steering system, and are the core foundation for ensuring the normal operation, safety performance, and service life of a car. Among them, small parts, such as small gears in the transmission, brake caliper housings in small cars, and brake caliper housings, often have burrs, flash, or oxide scale remaining on their surfaces after processing. These defects not only affect the assembly accuracy of the parts, but may also cause abnormal noises, accelerate wear, and even pose safety hazards during use due to friction. Therefore, polishing these small-batch produced parts to remove burrs and refine surface roughness is a key process to ensure their performance and reliability.

[0003] In existing technologies, polishing of the aforementioned small parts often employs vibratory polishing machines. The working principle involves a vibratory motor driving a vibratory tank to vibrate at high frequency, causing the abrasive material within the tank to fully contact and rub against the parts, thereby achieving deburring and polishing effects. However, in practical applications, after polishing, the parts and abrasive material accumulate mixed in the vibratory tank. Since there are many small parts inside the tank, they must be manually sorted out one by one from the abrasive material. This is not only labor-intensive but also has extremely low sorting efficiency and easily leads to parts being missed inside the vibratory tank, severely impacting production efficiency.

[0004] Therefore, a polishing device for processing automotive parts is needed to solve the above problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5A polishing device for processing automotive parts includes a base plate 1. An auxiliary part-picking mechanism is provided above the base plate 1. The auxiliary part-picking mechanism includes two vertical plates 2. The two vertical plates 2 are rotatably connected to a rotating shaft 3 via embedded bearings on opposite sides. The two rotating shafts 3 are fixedly connected to a connecting frame 4 on opposite sides. A polishing tank 5 located on the upper side and a storage tank 6 located on the lower side are fixedly connected between the two connecting frames 4. A transfer pipe 12 is connected between the polishing tank 5 and the storage tank 6. The transfer pipe 12 is equipped with a manually self-locking ball valve. A filter screen plate 7 is fixedly connected inside the polishing tank 5. A central column 8 is fixedly connected to the upper end of the filter screen plate 7. A sealing cover 11 is provided outside the polishing tank 5.

[0026] Locking mechanisms are provided on the opposite sides of the two rotating shafts 3;

[0027] A vibration mechanism is installed above the base plate 1.

[0028] In this embodiment: Before use, the rotation of the rotating shaft 3 is restricted by two locking mechanisms, thereby fixing the positions of the connecting frame 4, the polishing tank 5 and the storage bucket 6.

[0029] The small parts to be polished are placed into the abrasive in the polishing tank 5. The sealing cover 11 is then fixed to the top of the polishing tank 5 to prevent material splashing during subsequent vibration. The vibration generated is then transmitted to the polishing tank 5 through a vibration mechanism, causing the polishing tank 5 to produce high-frequency composite vibration. This thorough friction achieves deburring and polishing effects.

[0030] After polishing, the device needs to maintain vibration, and the manual self-locking ball valve of the transfer tube 12 should be opened. Since the mesh of the filter plate 7 allows abrasive to pass through but not parts, the abrasive inside the polishing tank 5 is transferred through the transfer tube 12 to the inside of the storage tank 6, while the parts are isolated at the top of the filter plate 7. After opening the sealing cover 11, the parts inside the polishing tank 5 can be directly removed. This method facilitates the separation of abrasive from small parts, avoiding the need for manual searching and sorting of small parts from the abrasive, significantly improving work efficiency and reducing labor intensity.

[0031] After the parts are removed, the sealing cover 11 is reinstalled on the upper side of the polishing tank 5. Then, the guide rod 20 is pulled upward, causing the connecting block 18 and the limiting post 24 to rise. The compression spring 19 is compressed. When the two limiting posts 24 are completely disengaged from the two limiting holes 16, the locking state of the rotating shaft 3 is released. Then, the polishing tank 5, the storage tank 6, and the connecting frame 4 are rotated 180° around the rotating shaft 3, so that the polishing tank 5 is on the lower side and the storage tank 6 is on the upper side. The abrasive inside the storage tank 6 will flow into the interior of the polishing tank 5 through the transfer pipe 12. Then, the manual self-locking ball valve of the transfer pipe 12 is closed. Subsequently, the polishing tank 5, the storage tank 6, and the connecting frame 4 are rotated 180° in the opposite direction around the rotating shaft 3, and the polishing tank 5 is rotated back to the upper side. Under the action of the compression spring 19, the two limiting posts 24 are reinserted into the interior of the two limiting holes 16, completing the limiting of the rotating shaft 3, and preparing for the next polishing.

[0032] As a technical optimization of this utility model, the locking mechanism includes a connecting shaft 14 fixedly connected to the end of the rotating shaft 3. The connecting shaft 14 passes through the vertical plate 2 and is fixedly connected to a disc 15. A limit hole 16 is opened on the outer wall of the disc 15. A limit post 24 is inserted into the inside of the limit hole 16. The upper end of the limit post 24 is fixedly connected to a connecting block 18 that fits against the outer wall of the disc 15. A fixing plate 17 is fixedly connected to the outer wall of the vertical plate 2. A compression spring 19 is fixedly connected between the fixing plate 17 and the connecting block 18. A guide rod 20 passing through the compression spring 19 is fixedly connected to the upper end of the connecting block 18. The guide rod 20 passes through the fixing plate 17 and is slidably connected to the fixing plate 17. A pull plate is fixedly connected to the upper end of the guide rod 20.

[0033] In this embodiment: In the locking mechanism, the connecting shaft 14 fixes the rotating shaft 3 and the disc 15, and the limiting hole 16 of the disc 15 cooperates with the limiting post 24 to achieve locking; the compression spring 19 pushes the connecting block 18 to insert the limiting post 24 into the limiting hole 16, restricting the rotation of the disc 15 and the rotating shaft 3; the guide rod 20 is pulled to drive the connecting block 18 to rise, and the limiting post 24 disengages from the limiting hole 16, releasing the lock.

[0034] As a technical optimization of this utility model, the vibration mechanism includes horizontal plates 22 that are fixedly connected to the opposite sides of the two vertical plates 2. Two support springs 23 are fixedly connected to the lower ends of the two horizontal plates 22. All four support springs 23 are fixedly connected to the base plate 1. Vibration motors 21 are installed on the opposite sides of the two vertical plates 2.

[0035] In this embodiment: In the vibration mechanism, the vibration motor 21 generates vibration and transmits it to the polishing tank 5; the support spring 23 cooperates with the vibration motor 21 to make the polishing tank 5 generate high-frequency vibration, providing conditions for the friction polishing of parts and abrasives.

[0036] As a technical optimization of this utility model, a guide ring 13 connected to the transfer pipe 12 is installed at the top of the inner wall of the storage barrel 6. The interior of the guide ring 13 has a conical structure.

[0037] In this embodiment: Since the guide ring 13 is connected to the transfer tube 12 and has a conical structure inside, the abrasive is guided into the interior of the transfer tube 12.

[0038] As a technical optimization of this utility model, a threaded column 9 is fixedly connected to the upper end of the central column 8, and a threaded cylinder 10 that is fixedly connected to the sealing cover 11 is threadedly connected to the outer wall of the threaded column 9.

[0039] In this embodiment: the threaded post 9 at the upper end of the central post 8 is connected to the threaded cylinder 10 fixed to the sealing cover 11 by threads. When tightened, the sealing cover 11 can tightly cover the outside of the polishing tank 5 to prevent materials from splashing out of the gap during vibration; when loosened, the sealing cover 11 can be opened to facilitate the placement of the parts to be polished or the removal of the abrasive.

[0040] As a technical optimization of this utility model, the upper end of the sealing cover 11 is fixedly connected with a plurality of handles evenly distributed along the circumference.

[0041] In this embodiment, multiple handles are provided to facilitate the rotation of the sealing cover 11.

[0042] As a technical optimization of this utility model, mounting plates are fixedly connected to both the left and right ends of the base plate 1.

[0043] In this embodiment, the device is fixed in place by setting two mounting plates.

[0044] The working principle and usage process of this utility model are as follows: Before use, the two limiting posts 24 are inserted into the limiting holes 16 of the two discs 15 under the elastic force of the two compression springs 19. The rotation of the rotating shaft 3 is restricted by the cooperation of the limiting posts 24 and the limiting holes 16, thereby fixing the position of the connecting frame 4, the polishing tank 5 and the storage bucket 6.

[0045] Place the small parts to be polished into the abrasive in the polishing tank 5. Then screw the threaded sleeve 10 of the sealing cover 11 into the outer wall of the threaded post 9 until the sealing cover 11 is tightly abutted against the upper end of the polishing tank 5, thereby preventing material from splashing during subsequent vibration.

[0046] Then, the two vibration motors 21 are started. The vibration generated by the vibration motors 21 is transmitted to the polishing tank 5. At the same time, the support spring 23 at the lower end of the horizontal plate 22 vibrates in coordination, causing the polishing tank 5 to generate high-frequency composite vibration. The deburring and polishing effects are achieved through sufficient friction.

[0047] After polishing, the device needs to maintain vibration, and the manual self-locking ball valve of the transfer tube 12 should be opened. Since the mesh of the filter plate 7 allows abrasive to pass through but not parts, the abrasive inside the polishing tank 5 is transferred through the transfer tube 12 to the inside of the storage tank 6, while the parts are isolated at the top of the filter plate 7. After opening the sealing cover 11, the parts inside the polishing tank 5 can be directly removed. This method facilitates the separation of abrasive from small parts, avoiding the need for manual searching and sorting of small parts from the abrasive, significantly improving work efficiency and reducing labor intensity.

[0048] After the parts are removed, the sealing cover 11 is reinstalled on the upper side of the polishing tank 5. Then, the guide rod 20 is pulled upward, causing the connecting block 18 and the limiting post 24 to rise. The compression spring 19 is compressed. When the two limiting posts 24 are completely disengaged from the two limiting holes 16, the locking state of the rotating shaft 3 is released. Then, the polishing tank 5, the storage tank 6, and the connecting frame 4 are rotated 180° around the rotating shaft 3, so that the polishing tank 5 is on the lower side and the storage tank 6 is on the upper side. Under the guidance of the guide ring 13, the abrasive inside the storage tank 6 will flow into the interior of the polishing tank 5 through the transfer pipe 12. Then, the manual self-locking ball valve of the transfer pipe 12 is closed, and the polishing tank 5, the storage tank 6, and the connecting frame 4 are rotated 180° in the opposite direction around the rotating shaft 3. The polishing tank 5 is rotated back to the upper side. Under the action of the compression spring 19, the two limiting posts 24 are reinserted into the interior of the two limiting holes 16, completing the limiting of the rotating shaft 3, and preparing for the next polishing.
