Description

Technical Field

[0001] The present invention relates to the technical field of parts processing, and particularly relates to a trimming processing device for vehicle rubber shock-absorbing bushings. Background Art

[0002] Rubber shock-absorbing bushings are mainly made of rubber. They are commonly used components in automotive suspension systems and other mechanical structures. Their main function is to provide buffering between moving parts, reduce vibration, noise, and wear. They are usually installed at positions such as control arms, steering knuckles, engine mounts, and transmission mounts to help absorb the impact force caused by road unevenness or other dynamic loads. Therefore, they play a crucial role in the automotive field. However, excess rubber is generated during the molding and vulcanization processes. To prevent lack of rubber, the rubber compound filled in the mold cavity will maintain a certain excess. During the mold pressing and vulcanization stage, the rubber compound quickly fills the mold cavity, and the excess rubber compound overflows through the mold parting surface to form flash. Therefore, trimming processing is required for rubber shock-absorbing bushings.

[0003] In the existing patent 201810811620.1, a trimming device for bushings used in automotive chassis suspensions includes a workbench, multiple support mechanisms, multiple feeding mechanisms, multiple trimming mechanisms, and multiple discharging mechanisms. The multiple feeding mechanisms are respectively arranged in one-to-one correspondence with the multiple support mechanisms. The feeding conveyor mechanism of the feeding mechanism is used to convey the workpiece to be processed into the feeding channel and feed it onto the first support device or the second support device through the feeding channel. The multiple trimming mechanisms are respectively arranged in one-to-one correspondence with the multiple support mechanisms, and the multiple trimming mechanisms are all installed on the workbench. The trimming mechanism is used to trim the workpieces on the first support device and the second support device. When the discharging assembly is in the first position state, it is used to clamp the processed workpieces on the first support device and the second support device.

The present invention can achieve automatic loading and unloading, and has high working efficiency.

[0004] In the above structure, automatic loading and unloading of bushings can be achieved. However, during the processing of rubber shock-absorbing bushings, flash phenomena occur at both ends of the bushings. Since the trimming of both ends of the bushings cannot be carried out, the bushings cannot meet the processing requirements, the shock-absorbing effect of the bushings is reduced, various performances of the bushings are affected, subsequent secondary processing of the bushings is required, the trimming processing efficiency of the bushings is reduced, time is wasted, the production cost of the enterprise is increased, and it is not conducive to the market competitiveness of the enterprise.

[0035] Embodiment 1:

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, a trimming processing device for a vehicle rubber shock-absorbing bushing of the present invention includes a support frame 1.

[0038] A receiving mechanism 10 is provided on the receiving cylinder 9. The receiving mechanism 10 receives and clamps the bushing. A transmission component 11 is provided between the rotating shaft 8 and the support frame 1. When the rotating mechanism 6 rotates, the transmission component 11 drives the rotating shaft 8 to rotate, so that the receiving cylinder 9 turns. A telescopic cutting knife 12 for cutting the flash of the bushing is provided on the support frame 1. The telescopic cutting knife 12 is a prior art and can be composed of an electric telescopic rod and a tool, and can realize telescoping to expand the cutting range;

[0039] A funnel 13 is provided on the support frame 1 below the rotating mechanism 6. A pressure-bearing component 14 communicated with the pushing component 5 is provided at the outlet end of the funnel 13.

[0040] Working principle: Place the rubber shock-absorbing bushing into the storage cylinder 2 through the feeding port 3. Use the pushing assembly 5 to push the bushing through the output pipe 4 and drop it onto the receiving mechanism 10. The receiving mechanism 10 clamps the bushing inside the receiving cylinder 9. Start the rotating mechanism 6, so that the bushing continuously drops into all the receiving cylinders 9, making both ends of the bushing just expose outside the receiving cylinder 9. When the receiving cylinder 9 receives and clamps the bushing, stop the rotating mechanism 6, start the telescopic cutter 12, and cut the flash at one end of the bushing inside the receiving cylinder 9. Continue to start the rotating mechanism 6, forcing the support plate 7, the receiving mechanism 10 and the receiving cylinder 9 to rotate. Under the action of the transmission assembly 11, the rotating shaft 8 also rotates at the same time until the upper and lower ends of the receiving cylinder 9 exchange positions, so that the upper and lower ends of the bushing inside the receiving cylinder 9 change directions, making the cut bushing face down and the uncut bushing face up. When the flash at the upper end of all the bushings inside the receiving cylinder 9 is cut, when the receiving cylinder 9 moves to the position of the telescopic cutter 12 again, the telescopic cutter 12 cuts the other end of the bushing, thus realizing the cutting of the flash at both ends of the bushing. Repeat the above steps to complete the cutting of the flash at both ends of all the bushings. When the telescopic cutter 12 cuts the flash at the upper and lower ends of the bushing, stop the rotating mechanism 6, use the receiving mechanism 10 to release the bushing, so that the bushing drops vertically along the receiving cylinder 9 under the action of the receiving cylinder 9, making the bushing drop into the funnel 13 and fall out of the outlet end of the funnel 13 onto the pressure-bearing assembly 14. The pressure-bearing assembly 14 is squeezed, dropping and collecting the bushing. The extrusion assembly is affected by the gravity of the bushing, so through the action of the output pipe 4, it drives the pushing assembly 5 to push the bushing in the storage cylinder 2 into the receiving cylinder 9, so that the receiving mechanism 10 receives and clamps the bushing again, completing the closed-loop of the flash treatment of the bushing; In summary, a trimming and processing device for vehicle rubber shock-absorbing bushings of the present application can realize the trimming and processing of the flash on both sides of the bushing at one time, making the bushing meet the processing requirements, improving the shock-absorbing function effect of the bushing, improving the performance of the bushing, without subsequent secondary trimming and processing. When automatically feeding the bushing, it ensures the automatic and timely feeding of the bushing, improves the intelligence of the device, thus realizing the continuous processing of the bushing, ensuring the consistency of the product, improving the trimming and processing efficiency of the bushing, saving time, reducing the production cost of the enterprise, and being beneficial to the market competitiveness of the enterprise.

A roller 1102 is arranged inside the annular guide rail 1101. A shaft rod 1103 is connected to the roller 1102 by bearings. The shaft rod 1103 is connected to the support plate 7 by bearings.

The rotating gear 1106 is located inside the annular guide rail 1101. The shaft rod 1103 forces the rotating gear 1106 to move along the annular guide rail 1101. A sector-shaped internal rack 1107 meshing with the rotating gear 1106 is arranged on the annular guide rail 1101.

[0049] As Figure 7 and Figure 8 shown, for a trimming and processing device for a vehicle rubber shock-absorbing bushing according to the present invention, a limiting assembly 16 is arranged on the support plate 7. The limiting assembly 16 includes an electromagnet 1601 arranged on the support plate 7. A rotating block 1602 is fixedly sleeved on the shaft rod 1103. Magnet stones 1603 are arranged on both sides of the rotating block 1602. The electromagnet 1601 attracts the magnet stones 1603 to limit the shaft rod 1103 from rotating along with the roller 1102.

[0050] As Figure 1 , Figure 2 and Figure 11 shown, for a trimming and processing device for a vehicle rubber shock-absorbing bushing according to the present invention, the pressure-bearing assembly 14 includes a support rod 1401 arranged on the funnel 13. A second cylinder 1402 is installed on the support rod 1401. Gases are filled in both the first cylinder 501 and the second cylinder 1402. A pressure-bearing plug 1403 is arranged inside the second cylinder 1402. A pressure-bearing rod 1404 penetrating through the second cylinder 1402 is arranged on the pressure-bearing plug 1403. A cone 1405 adapted to the outlet end of the funnel 13 is arranged on the pressure-bearing rod 1404. A second spring 1406 sleeved on the outer circle of the pressure-bearing rod 1404 is arranged between the second cylinder 1402 and the cone 1405. A conduit 1407 communicating with the first cylinder 501 is arranged on the second cylinder 1402.

[0051] Working principle: When the device is in the vacant state, the bushings are sequentially placed into the storage cylinder 2 through the feeding port 3, and another bushing is directly dropped into the funnel 13, so that the bushing falls onto the pressure-bearing assembly 14, forcing the pushing assembly 5 to move. The pushing assembly 5 is forced to push the bushings in the storage cylinder 2 forward. By repeating the operation, multiple bushings are continuously pushed forward until the storage cylinder 2 is filled with bushings, and each receiving cylinder 9 receives a bushing respectively through the action of the output pipe 4;

[0052] When the receiving cylinder 9 receives and clamps the bushing, the electric push rod 1001 located below the receiving cylinder 9 is started, and the electric push rod 1001 drives the support ring 1002 to move downward to a reasonable position. At this time, there is a certain distance between the arc-shaped clamping plate 1007 and the receiving cylinder 9, and this distance is the part of the bushing that is exposed. The rotating ring 1003 moves along. The motor three 1005 below is started, and the output shaft of the motor three 1005 rotates to drive the threaded rod 1006 to rotate. Under the action of the guiding rod 1008, the two arc-shaped clamping plates 1007 move closer to each other until the two arc-shaped clamping plates 1007 are both below the port of the receiving cylinder 9. The bushing falls into the receiving cylinder 9 through the output pipe 4 until the tops of the two arc-shaped clamping plates 1007 below abut against one end of the bushing, and the other end of the bushing is exposed from the receiving cylinder 9; The upper electric push rod 1001 is started, and the electric push rod 1001 drives the support ring 1002 to move to a reasonable position, and the rotating ring 1003 moves along until the two arc-shaped clamping plates 1007 above are flush with the top surface of the receiving cylinder 9. The upper motor three 1005 is started, and the output shaft of the motor three 1005 rotates to drive the threaded rod 1006 to rotate. Under the action of the guiding rod 1008, the two arc-shaped clamping plates 1007 move closer to each other until the two arc-shaped clamping plates 1007 clamp the bushing exposed from the receiving cylinder 9; The motor three 1005 and the electric push rod 1001 below are adjusted again to force the two arc-shaped clamping plates 1007 below to clamp the bushing, so as to achieve the effect of the receiving cylinder 9 receiving and clamping the bushing;

[0053] When cutting the upper end of the bushing, the telescopic cutter 12 is forced to be located at the flash of the bushing. The motor two 1501 is started, and the output shaft of the motor two 1501 rotates to drive the driving gear 1502 to rotate. The driving gear 1502 rotates to drive the driven gear to rotate, so that the rotating ring 1003 rotates, forcing the bushing in the receiving cylinder 9 to rotate, so that the telescopic cutter 12 trims and cuts the flash at the upper end of the bushing;

[0054] The motor one 606 is started, and the output shaft of the motor one 606 rotates to drive the rotating rod 603 to rotate. The rotating rod 603 drives the rotating disk 604 to rotate. The rotating disk 604 drives the support plate 7 to rotate until the next receiving cylinder 9 drives the bushing to be located at the telescopic cutter 12. The motor one 606 is stopped, and the above operation is repeated to complete the trimming and cutting treatment of the upper ends of all bushings;

[0055] For the flash treatment at the lower end of the bushing, when the next receiving cylinder 9 is rotated to the telescopic cutter 12, the rotating disk 604 rotates, causing the rotating disk 604 to drive the support plate 7, the receiving mechanism 10, the rotating shaft 8 and the receiving cylinder 9 to rotate. The support plate 7 drives the shaft rod 1103 to rotate, and the shaft rod 1103 drives the roller 1102 to roll along the annular guide rail 1101. The electromagnet 1601 is energized, causing the electromagnet 1601 to attract the magnet stone 1603, thereby restricting the rotation of the shaft rod 1103;

[0056] The rotating gear 1106 runs on the annular guide rail 1101 following the shaft rod 1103. When the shaft rod 1103 rotates to the sector internal rack 1107, the rotating gear 1106 meshes with the sector internal rack 1107, causing the rotating gear 1106 to rotate. When the shaft rod 1103 overcomes the attraction force, the rotating gear 1106 drives the shaft rod 1103 to rotate. The shaft rod 1103 drives the driving bevel gear 1104 to rotate, and the driving bevel gear 1104 drives the driven bevel gear 1105 to rotate, thereby causing the rotating shaft 8 to rotate. The rotating shaft 8 drives the receiving cylinder 9 to turn over, causing the upper and lower positions of the receiving cylinder 9 to be exchanged, so that the untrimmed lower end of the bushing is in the upper part. At this time, just the rotating gear 1106 passes through the sector internal rack 1107, and the roller 1102 continues to run on the annular guide rail 1101. The electromagnet 1601 attracts the magnet stone 1603, restricting the shaft rod 1103 from rotating following the roller 1102, thereby restricting the rotating shaft 8 from driving the receiving cylinder 9 to rotate freely;

[0057] When the receiving cylinder 9 rotates to the telescopic cutter 12 for the second time, the flash at the lower end of the bushing is at the upper end. Repeat the above steps to cut and trim the flash until the flashes at both ends of all bushings are trimmed;

[0058] When both ends of the bushing are trimmed, it is necessary to release the bushing inside the receiving cylinder 9. Start the motor three 1005 at both ends of the receiving cylinder 9. The output shaft of the motor three 1005 rotates to drive the threaded rod 1006 to rotate. Under the action of the guide rod 1008, the two arc-shaped clamping plates 1007 move away from each other until the two arc-shaped clamping plates 1007 are separated from the bushing inside the receiving cylinder 9. Under the action of gravity, the bushing falls along the receiving cylinder 9, and the bushing falls into the funnel 13 through the through hole 605 on the rotating disk 604;

[0059] The bushing falls from the funnel 13 onto the cone 1405. Under the gravitational force of the bushing, the cone 1405 drives the pressure-bearing rod 1404 to move, increasing the distance between the cone 1405 and the outlet of the funnel 13, thereby collecting the fallen bushing. The movement of the pressure-bearing rod 1404 forces the pressure-bearing plug 1403 to move within the second cylinder 1402, compressing the gas within the second cylinder 1402. At this time, the second spring 1406 is compressed. Under the gas guiding action of the conduit 1407, the gas within the second cylinder 1402 is forced to be compressed and enter the first cylinder 501. The gas in the first cylinder 501 increases and the pressure rises, thereby pushing the pushing plug 502 to move. The pushing plug 502 drives the pushing rod 503 to move, and the pushing rod 503 drives the pushing plate 504 to move. When the pushing plate 504 moves one process, the pushing plate 504 pushes the bushing at the output pipe 4 to fall through the output pipe 4 into the receiving cylinder 9, and the trimming operation of the next bushing flash continues; after the bushing falls from the cone 1405, the second spring 1406 returns to its original state, causing the gas in the first cylinder 501 and the second cylinder 1402 to return to their original states, forcing the pressure-bearing rod 1404 and the cone 1405 to retract to their original positions, and forcing the pushing rod 503 and the pushing plate 504 to return to their original positions;

[0060] The arrangement of the pushing component 5 can successively supplement the bushings in the storage cylinder 2 into the receiving cylinder 9, ensuring that the receiving cylinder 9 always holds and clamps the bushings, timely replenishing the bushings, improving the processing efficiency of the device for the bushings, and being able to communicate with the pressure-bearing component 14 to achieve the connectivity of material feeding and loading, enhancing the intelligence of the device; the arrangement of the rotating mechanism 6 can rotate the receiving cylinder 9, enabling the untrimmed bushings to keep up in time, realizing the continuous processing of the bushings. At the same time, it can force the transmission component 11 to move, so that after the first trimming of the bushing, the bushing is forced to deflect and trimmed again, completing the trimming process of the flash on both sides of the bushing at one time, making the bushing meet the processing requirements; the arrangement of the receiving mechanism 10 can achieve the effect of receiving and clamping the bushing, providing a supporting effect for the bushing, preventing the bushing from falling when the receiving cylinder 9 rotates, improving the stability of the device, determining the clamping position of the bushing, making the parts of both ends of the bushing exposed outside the two ends of the receiving cylinder 9 the same, improving the operation consistency of the device, and facilitating the trimming operation of the telescopic cutter 12 on the bushing; the arrangement of the rotating mechanism 15 enables the rotating ring 1003 to rotate, and under the clamping action at the upper and lower ends, the rotation of the bushing is realized, facilitating the telescopic cutter 12 to cut and trim the periphery of the bushing, improving the integrity of the trimming of the bushing by the device and facilitating the thorough treatment of the trimming; the arrangement of the transmission component 11 can transmit the rotational force of the rotating disk 604, change the direction of the force, so that the shaft rod 1103 and the rotating shaft 8 rotate, forcing the upper and lower ends of the receiving cylinder 9 to exchange positions, and ensuring that the bushing rotates around the rotating disk 604, facilitating the telescopic cutter 12 to process the two ends of the bushing; the arrangement of the limiting component 16 can limit the free rotation of the shaft rod 1103 following the roller 1102, improving the stability of the device. When the shaft rod 1103 rotates under force, the shaft rod 1103 will overcome the attraction of the electromagnet 1601 and the magnet stone 1603, and the shaft rod 1103 completes the rotation. When the rotating gear 1106 passes by the sector internal rack 1107, the electromagnet 1601 will attract the magnet stone 1603 on the other side and limit the shaft rod 1103 again, improving the flexibility of the device; the arrangement of the pressure-bearing component 14 can respond to the dropping of the bushing, drive the pushing component 5 to act by the gravity of the bushing, ensure the automatic and timely loading of the bushing when the bushing is automatically unloaded, improve the intelligence of the device, and at the same time release and unload the bushing to complete the collection of the bushing.

[0061] This solution can achieve automatic feeding into the receiving cylinder 9, trimming the upper ends of all bushings. After the first trimming is completed, the receiving cylinder 9 rotates, and the lower ends of all bushings are trimmed for the second time. After trimming both ends of all bushings in sequence, automatic discharging operation is carried out, achieving the purpose of automatic loading and unloading. It can timely supplement bushings into the receiving cylinder 9, improve intelligence, enhance the performance of bushings, realize continuous processing of bushings, ensure product consistency, improve the trimming processing efficiency of bushings, save time, reduce the production cost of enterprises, and be conducive to the market competitiveness of enterprises.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
