Description

Technical Field

[0001] The present invention relates to the technical field of bushing polishing, and particularly to a polishing device for processing hardware parts. Background Art

[0002] Hardware parts generally refer to various small mechanical or equipment components made of metal materials. Due to their durability and strength, these parts are widely used in multiple industries such as construction, manufacturing, automotive, and aerospace. Among them, the bushing, as a common hardware part, is widely used in various mechanical equipment to ensure the precise fit and stable operation between the shaft and other components.

[0003] After the bushing is produced, in order to improve its surface quality and durability, it usually needs to be subjected to surface grinding and polishing treatment. This process is crucial for ensuring that the bushing can achieve the expected functions in actual applications. However, existing polishing devices can usually only perform single polishing treatment on the inner wall or outer wall of the bushing, which means that in actual operation, it is necessary to manually transfer the bushing from a device dedicated to inner wall polishing to another device for outer wall polishing. This operation process not only reduces the polishing efficiency, but also in the process of batch processing, the frequent transfer of manual operations not only consumes time, but also may introduce additional risks of human errors. For example, the bushing may be damaged or lost during the transfer process, thus increasing the workload and complexity of manual operations. Summary of the Invention

[0004] In view of this, the present invention provides a polishing device for processing hardware parts, which can overcome the disadvantages that existing polishing devices can usually only perform single polishing treatment on the inner wall or outer wall of the bushing and have low polishing efficiency.

[0009] Furthermore, it further includes a feeding rack, a wedge-shaped rod, and an arc-shaped baffle. The feeding rack and the wedge-shaped rod are connected to the mounting frame, and the wedge-shaped rod is in contact with the side of the rotating disk. The arc-shaped baffles are circumferentially and evenly spaced and connected to the rotating disk.

[0010] Furthermore, it further includes an air pump, a hose, a sliding pipe, an annular nozzle, and a collecting assembly. The air pump is connected to the side of the bracket, the sliding pipe is slidably connected to the bracket, both ends of the hose communicate with the end of the sliding pipe and the air outlet of the air pump respectively. The annular nozzle is installed at the end of the sliding pipe and is rotatably connected to the lower rotating rod. The collecting assembly is used to collect the debris blown out of the shaft sleeve.

[0011] Furthermore, the collecting assembly includes a dust collecting pipe, a fixing frame, a collecting frame, and a filter screen. The dust collecting pipe is connected to the bracket, and the upper end of the dust collecting pipe communicates with the round hole.

Ventilation holes are symmetrically formed in the fixing frame. The collecting frame is placed inside the fixing frame, and the filter screens are symmetrically connected to both sides of the collecting frame.

[0012] Furthermore, it further includes a discharge inclined frame, a filtering frame, and a fixed brush. The discharge inclined frame is connected to the mounting frame and is located directly below the rotating disk. The filtering frame is installed inside the discharge inclined frame.

Specific embodiments

[0028] Reference to an embodiment in this text means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0029] Embodiment: A polishing device for processing hardware parts, as Figures 1 - 8 shown, includes a mounting bracket 1, a rotating disk 2, a driving motor I 3, a bracket 4, an arc plate 5, a guide rod 6, a sliding plate 7, an electric push rod 8, a rotating rod 9, a grinding wheel 10, a rotating assembly, a driving assembly, and a fixing assembly. The rotating disk 2 is rotatably connected to the middle of the upper part of the mounting bracket 1. The front part of the rotating disk 2 is circumferentially and evenly spaced with U-shaped through holes 201, and the rear part of the rotating disk 2 is circumferentially and evenly spaced with round holes 202, and the round holes 202 correspond to the U-shaped through holes 201 one by one and are horizontally aligned. The driving motor I 3 is connected to the upper part of the front side of the mounting bracket 1 and is connected to the rotating shaft of the rotating disk 2 through its output shaft. The bracket 4 is connected to the middle of the top surface of the mounting bracket 1. The shape of the bracket 4 is an inverted U shape, and the bracket 4 is located above the rotating disk 2. A plurality of arc plates 5 are circumferentially and evenly spaced and connected to the rotating disk 2, and the round holes 202 and the U-shaped through holes 201 are respectively located on the front and rear sides of the arc plate 5. The guide rod 6 is connected to the upper part of the front side of the bracket 4. The sliding plate 7 is slidably connected to the guide rod 6. The electric push rod 8 is connected to the top surface of the bracket 4, and the telescopic rod of the electric push rod 8 is connected to the upper part of the rear side of the sliding plate 7. Two rotating rods 9 are rotatably connected to the sliding plate 7, and the rear ends of the two rotating rods 9 pass through the front side of the bracket 4 and can rotate on the front side of the bracket 4. The bracket 4 can provide support for the rotating rod 9 and does not affect the forward and backward movement and rotation of the rotating rod 9. The grinding wheel 10 is installed at the rear end of the rotating rod 9 (in order to Figure 1The driving assembly is used to drive the rotating rod 9 to rotate, the rotating assembly is used to drive the shaft sleeve in the arc plate 5 to rotate, and the fixing assembly is used to fix the shaft sleeve in the arc plate 5.

[0030] like Figure 5 As shown, the driving assembly includes a driving motor II 11, a driving gear 12 and a driven gear 13. The driving motor II 11 is connected to the middle of the front side of the sliding plate 7 (with Figure 1 The output shaft of the driving motor II 11 rotates and passes through the side of the sliding plate 7. The driving gear 12 is connected to the output shaft of the driving motor II 11. The two rotating rods 9 are respectively located on the upper and lower sides of the driving gear 12. The front ends of the two rotating rods 9 are connected to driven gears 13, and the two driven gears 13 are meshed with the driving gear 12.

[0031] like Figure 6 As shown, the rotating assembly includes an electric roller 14 and an auxiliary roller 15. Two electric rollers 14 are symmetrically installed on each arc plate 5. The outer side of the electric roller 14 is covered with a rubber sleeve. Four auxiliary rollers 15 are symmetrically rotatably connected to each arc plate 5.

[0032] like Figure 7 and Figure 8 As shown, the fixing assembly includes a sliding frame 16, a connecting spring 17, a connecting ring 18 and a rotating ring 19. The sliding frame 16 is slidably connected to the front side of the rotating disk 2 at uniform intervals in the circumferential direction. The sliding frame 16 corresponds to the U-shaped through hole 201 one by one and is aligned laterally. The sliding frame 16 is located at the front side of the U-shaped through hole 201 corresponding thereto, and the connecting spring 17 is wound around the sliding frame 16. The two ends of the connecting spring 17 are respectively connected to the front part of the sliding frame 16 and the front side of the rotating disk 2. The rear part of the rotating disk 2 is connected to the connecting ring 18 at uniform intervals in the circumferential direction. The rear sides of multiple sliding frames 16 are also connected to the connecting ring 18. The connecting rings 18 on the front and rear sides are respectively located on the front and rear sides of the arc plate 5. The sides of the connecting rings 18 on the front and rear sides that are close to each other are rotatably connected to the rotating ring 19, and the thickness of the connecting ring 18 and the rotating ring 19 are both less than the thickness of the shaft sleeve, so that when the grinding wheel 10 moves backward and contacts the shaft sleeve, the connecting ring 18 and the rotating ring 19 will not block the grinding wheel 10.

[0033] When it is necessary to use this device to polish the bushing, the sliding frame 16 can be pulled forward first, the connecting spring 17 is stretched, and the sliding frame 16 can drive the front connecting ring 18 and the front rotating ring 19 to move forward. Then, the bushing is placed into the arc-shaped plate 5 so that the bushing is located between the front and rear rotating rings 19. Then, the sliding frame 16 is released, and the connecting spring 17 will return to its original state, driving the sliding frame 16 to move backward and reset. The sliding frame 16 can drive the front connecting ring 18 and the front rotating ring 19 to move backward and reset, so that the front and rear rotating rings 19 can clamp the front and rear ends of the bushing. Then, the electric roller 14 can drive the bushing to rotate automatically in the arc-shaped plate 5 through the friction force between the rubber sleeve on it and the bushing. The bushing can drive the auxiliary roller 15 and the rotating ring 19 to rotate through the friction force, without affecting the clamping of the bushing by the rotating ring 19. Then, the drive motor I 3 can be used to drive the rotating disk 2 to rotate intermittently. The rotating disk 2 can drive the bushing to rotate through the arc-shaped plate 5. Whenever the rotating disk 2 stops rotating, the operator can repeat the above operation to place the next bushing into the next arc-shaped plate 5 until the bushing rotates to the rear of the grinding wheel 10 along with the rotating disk 2. Then, the drive motor II 11 can be controlled to drive the driving gear 12 to rotate. The driving gear 12 can drive the driven gear 13, the rotating rod 9, and the grinding wheel 10 to rotate. At the same time, the telescopic rod of the electric push rod 8 can be controlled to shorten, driving the sliding plate 7 to move backward along the guide rod 6. The sliding plate 7 can drive the rotating rod 9 and the grinding wheel 10 to move backward. Both grinding wheels 10 can pass through the U-shaped through hole 201, and both grinding wheels 10 can contact the top surface and the inner bottom surface of the bushing respectively. At this time, the bushing is rotating automatically. As the grinding wheel 10 continues to move backward, both grinding wheels 10 can polish the outer wall and the inner wall of the bushing respectively. Then, the telescopic rod of the electric push rod 8 is controlled to extend, driving the sliding plate 7 to move forward along the guide rod 6 and reset. The sliding plate 7 can drive the rotating rod 9 and the grinding wheel 10 to move forward and reset, separating the grinding wheel 10 from the bushing. At this time, the rotation of the rotating disk 2 can drive the next bushing to rotate to the rear of the grinding wheel 10. In this way, the outer wall and the inner wall of the bushing can be polished automatically in batches, improving the polishing efficiency. Finally, the sliding frame 16 can be pulled forward to drive the front rotating ring 19 to move forward, so that the two rotating rings 19 release the polished bushing. Then, a new bushing is placed in, and then the sliding frame 16 is released, enabling the front rotating ring 19 to move backward and reset to clamp the new bushing.

[0034] Such as Figure 9As shown in the figure, it further includes a feeding rack 20, a wedge-shaped rod 21 and an arc-shaped baffle 22. The feeding rack 20 is connected to the upper right side of the mounting rack 1. The top surface of the feeding rack 20 is an inclined surface that is lower on the left and higher on the right. The front side of the upper part of the mounting rack 1 is connected with a wedge-shaped rod 21. The rear side surface of the wedge-shaped rod 21 is close to the front side surface of the rotating disc 2. And the wedge-shaped rod 21 is arc-shaped, and the left end of the wedge-shaped rod 21 is an inclined surface. The sliding rack 16 can contact with the inclined surface at the left end of the wedge-shaped rod 21 as the rotating disc 2 rotates counterclockwise. The arc-shaped baffles 22 are circumferentially and evenly spaced and connected to the rotating disc 2, and the arc-shaped baffles 22 are located between two adjacent arc-shaped plates 5.

[0035] Initially, the sliding racks 16 in contact with the wedge-shaped rod 21 are all squeezed and move forward for a certain distance, and the corresponding connecting springs 17 are in a stretched state; when manual feeding of the bushings is required, only the bushings need to be placed on the feeding rack 20 in sequence, so that the bushings can roll leftward along the top surface of the feeding rack 20, so that the leftmost bushing on the feeding rack 20 can automatically enter one of the arc-shaped plates 5. As the rotating disc 2 rotates intermittently, the rotating disc 2 can drive the arc-shaped plate 5, the sliding rack 16 and the arc-shaped baffle 22 to rotate. When the sliding rack 16 rotates to separate from the wedge-shaped rod 21, the corresponding connecting spring 17 will return to its original state, so as to drive the front rotating ring 19 to move backward, so that the front and rear rotating rings 19 clamp the bushing in the arc-shaped plate 5. At this time, the arc-shaped baffle 22 on the rotating disc 2 can block the remaining bushings on the feeding rack 20. When the rotating disc 2 stops rotating, the next arc-shaped plate 5 will just be located on the left side of the feeding rack 20, so that the next bushing can automatically roll leftward and fall into the next arc-shaped plate 5. In this way, the feeding function of the bushings can be automatically completed; after the bushings are polished, the rotating disc 2 can drive the polished bushings to rotate through the arc-shaped plate 5. When the polished bushing rotates to below the rotating disc 2, the corresponding sliding rack 16 will contact with the wedge-shaped rod 21, and the wedge-shaped rod 21 will squeeze the sliding rack 16 to move forward, driving the front rotating ring 19 to move forward, so that the front and rear rotating rings 19 release the polished bushing, and the polished bushing can fall downward due to gravity for automatic discharging.

[0036] As Figure 10 and Figure 11As shown in the figure, it further includes an air pump 23, a hose 24, a sliding tube 25, an annular nozzle 26 and a collection assembly. The air pump 23 is connected to the upper part of the front side of the bracket 4. The sliding tube 25 is slidably connected to the upper part of the front side of the bracket 4, and the sliding tube 25 is located on the right side of the lower rotating rod 9. The two ends of the hose 24 are respectively communicated with the front end of the sliding tube 25 and the air outlet of the air pump 23. The annular nozzle 26 is installed at the rear end of the sliding tube 25, and the annular nozzle 26 is rotatably connected to the rear end of the lower rotating rod 9. The collection assembly is used to collect the debris blown out of the shaft sleeve. The collection assembly includes a dust collection tube 27, a fixed frame 28, a collection frame 29 and a filter screen 2901. The dust collection tube 27 is connected to the upper side of the rear part of the bracket 4, and the upper end of the dust collection tube 27 is in contact with the rear side of the rotating disk 2. As the rotating disk 2 rotates, the circular hole 202 on the rotating disk 2 can rotate to communicate with the upper end of the dust collection tube 27. The fixed frame 28 is connected to the lower side of the rear part of the bracket 4, and the lower end of the dust collection tube 27 is communicated with the top surface of the fixed frame 28. A plurality of ventilation holes 2801 are spaced apart from the upper parts of the left and right sides of the fixed frame 28. The collection frame 29 is placed in the fixed frame 28. The upper parts of the left and right sides of the collection frame 29 are respectively connected with a filter screen 2901, and the filter screen 2901 is flush with the height of the ventilation holes 2801.

[0037] When the rotating rings 19 on the front and rear sides clamp the shaft sleeve in the arc-shaped plate 5, the rear end of the shaft sleeve can communicate with the circular hole 202. When the rotating rod 9 moves backward, the lower rotating rod 9 can drive the annular nozzle 26 and the sliding tube 25 to move backward. When the lower grinding wheel 10 is polishing the inner wall of the shaft sleeve, air can be injected into the hose 24 through the air pump 23. The air in the hose 24 can enter the annular nozzle 26 through the sliding tube 25, so that the annular nozzle 26 can blow air backward, thereby blowing the debris generated by polishing the inner wall of the shaft sleeve backward, preventing the debris from remaining on the inner wall of the shaft sleeve and affecting the subsequent polishing effect of the inner wall of the shaft sleeve, and enabling the debris to pass through the circular hole 202, the dust collection tube 27 and the fixed frame 28 into the collection frame 29 in sequence. The air in the collection frame 29 can be discharged outward through the filter screen 2901 and the ventilation holes 2801. The filter screen 2901 can prevent the debris in the collection frame 29 from floating out. After a certain amount of debris is stored in the collection frame 29, the collection frame 29 can be pulled out backward to facilitate the unified treatment of the debris in the collection frame 29. When the rotating rod 9 moves forward to reset, the lower rotating rod 9 can drive the annular nozzle 26 and the sliding tube 25 to move forward to reset.

[0038] As Figure 12 and Figure 13As shown in the figure, it further includes a discharge inclined frame 30, a filter frame 31 and a fixed brush 32. The discharge inclined frame 30 is connected to the lower part of the mounting frame 1, and the discharge inclined frame 30 is located directly below the rotating disk 2. The filter frame 31 is detachably installed on the lower side inside the discharge inclined frame 30. The top surface of the filter frame 31 is inclined with the left side higher than the right side. The fixed brush 32 is connected to the upper side inside the discharge inclined frame 30, and the fixed brush 32 contacts the rotating disk 2 and the arc-shaped plate 5. Since debris will also be generated during the polishing of the outer wall of the bushing, the debris may adhere to the outer wall of the bushing or the surfaces of the rotating disk 2 and the arc-shaped plate 5. When the rotating rings 19 on the front and rear sides release the polished bushing, the polished bushing will fall down onto the top surface of the filter frame 31. At this time, the bushing will vibrate, enabling the debris adhering to the outer wall of the bushing to fall down through the filter frame 31 into the discharge inclined frame 30. Subsequently, the bushing can roll to the right along the top surface of the filter frame 31 for discharging. As the rotating disk 2 and the arc-shaped plate 5 rotate, the fixed brush 32 can scrape off the debris adhering to the surfaces of the rotating disk 2 and the arc-shaped plate 5, causing the debris to fall into the discharge inclined frame 30 for convenient subsequent unified treatment.

[0039] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
