The end of the knocking rod close to the T-shaped plate is provided with an arc surface 1 for generating vibration by colliding with the surface of the T-shaped plate. The free end of the telescopic elastic rod 2 is fixedly connected to the surface of the knocking rod. A transmission belt is connected between the reciprocating screw rod 3 and the reciprocating screw rod 2 to further improve the cleaning effect of the air bag surface, further remove fine impurities remaining after vibration or dispersed dust, and form a vibration loosening and contact cleaning method.

[0011] The scraper is connected to the reciprocating screw rod three by a threaded connection, the scraper is slidably connected to the circumferential surface of the fixed plate, and a spring for resetting is provided between the limiting rod and the scraper, which significantly improves the cleanliness of the air bag surface, reduces the risk of contamination during the installation process, and improves the product yield.

[0012] The surface of the scraper is provided with a processing device for performing corresponding operations based on whether it meets the standards.

This function realizes the automatic linkage between the inspection results and the sorting action, avoiding the flow of unqualified products into the next process, while reducing the labor intensity of manual sorting, improving the intelligence level of the production line, and ensuring the stability and consistency of product quality.

[0014] A method for automatically flanging an airbag for assembling an automobile bag-type air spring, using the above-mentioned automatic flanging device for assembling an automobile bag-type air spring, comprises: Step 1: The staff places the air bag on the surface of the placement table, pre-fills the air bag with some gas, and then starts the hydraulic cylinder. The output end of the hydraulic cylinder moves downward to drive the placement table to move. At the same time, the placement table moves downward to drive the T-shaped plate to move. The T-shaped plate moves downward to drive the reciprocating screw to rotate. Step 2: The reciprocating screw rod 1 rotates to drive the gear plate 1 to rotate. Since the gear plate 1 is engaged with the gear plate 2, the rotation of the gear plate 1 drives the gear plate 2 to rotate. At the same time, the rotation of the gear plate 2 drives the reciprocating screw rod 2 to rotate. Step 3: The reciprocating screw 2 rotates to drive the sliding table to move closer to the placement table. At the same time, the movement of the sliding table drives the clamping plate to move. Then, the clamping plate contacts and clamps the air bag under the action of the sliding table. Step 4: The sliding table moves toward the placement table under the action of the reciprocating screw rod 2, driving the clamping rod to move. The movement of the clamping rod drives the telescopic elastic rod 1 to move. At the same time, the movement of the telescopic elastic rod 1 drives the limit clamping plate to move. Subsequently, the limit clamping plate moves toward the placement table under the action of the telescopic elastic rod 1 until it contacts the circumferential surface of the air spring. The clamping rod adapts to the shape change of the air spring due to inflation through the elastic deformation of the free end of the telescopic elastic rod 1. Step 5: After the air bag is clamped and fixed, start the flange hydraulic column to move downward. The movement of the flange hydraulic column drives the flange installed at the bottom to move until it contacts the top of the air bag. Then the flange hydraulic column continues to move downward to squeeze the air bag. At this time, the air bag is flanging under the action of the flange so that it can enter the groove of the flange to achieve locking. At this time, the flange hydraulic column pumps gas into the interior of the air bag until it is fully expanded. Then it drives the clamping plate to continue to move towards the air bag to detect it. The beneficial effects of the embodiments of the present invention are: In the present invention, the reciprocating screw rod 2 is connected to the sliding table through a threaded connection, and the rotation of the reciprocating screw rod 2 drives the sliding table to move toward the placement table. At the same time, the movement of the sliding table drives the clamping plate to move. Subsequently, the clamping plate contacts and clamps the air bag under the action of the sliding table, thereby achieving a fixed clamping effect on the air spring, improving the stability and reliability of the air bag in the subsequent flanging process, further improving the flanging effect and yield rate, and providing a stable operating basis for the subsequent flanging process.

[0015] In the present invention, the limiting clamp moves toward the placement table under the action of the telescopic elastic rod until it contacts the circumferential surface of the air spring. The clamping rod adapts to the shape change of the air spring due to inflation through the elastic deformation of the free end of the telescopic elastic rod, thereby limiting the air spring and avoiding the hard squeezing damage to the airbag surface caused by traditional rigid limiting. At the same time, it ensures that the airbag is always in the preset position during the inflation process, improves the limiting accuracy, reduces the flange offset or wrinkles caused by deformation, and ensures the consistency of the flange quality.

[0016] In the present invention, the knocking rod moves to contact and collide with the surface of the T-shaped plate to generate vibration. At this time, the vibration of the T-shaped plate transmits the vibration to the air bag to shake off the dust accumulated on the surface of the air bag, and foreign matter that affects the installation of the flange can be removed in advance, avoiding impurities being sandwiched between the air bag and the flange groove, resulting in sealing failure or decreased structural strength, thereby improving the sealing and service life of the product from the source. The three rotations of the reciprocating screw drive the scraper to move in the direction close to the eccentric wheel. The movement of the scraper cleans the dust or impurities on the top of the air bag, further improving the cleaning effect of the air bag surface, and further removing the fine impurities or dispersed dust remaining after the vibration, forming a vibration loosening and contact cleaning cleaning, significantly improving the cleanliness of the air bag surface, reducing the pollution risk during the installation process, and improving the product yield.

[0017] In the present invention, the marking plate is driven to rotate counterclockwise by the rotation of the fixed rod, and the rotation of the marking plate marks the air bags that meet the standards, thereby achieving permanent marking of qualified air bags, ensuring uniform marking positions and accurate information, facilitating subsequent traceability and quality control, and at the same time improving production efficiency, reducing problems of human omissions or mislabeling, and eliminating the need for human intervention, thereby improving marking accuracy.

[0018] In the present invention, the free end of the telescopic rod is driven to move toward the placement table by the rotation of the linkage rod. The free end of the placement table moves until the air bag is pushed out through the opening opened on the surface of the placement table, thereby achieving the effect of corresponding treatment of the air bag after the inspection. This function realizes the automatic linkage between the inspection result and the sorting action, preventing unqualified products from flowing into the next process, and at the same time reducing the labor intensity of manual sorting, improving the intelligence level of the production line, and ensuring the stability and consistency of product quality.

[0027] like Figures 1 to 7 As shown, it shows an automatic flanging device and method for assembling an air bag for an automobile bag-type air spring in one embodiment of the present invention, including a flanging machine 1, a flange hydraulic column 2 is fixedly installed on the surface of the flanging machine 1, an air pipe 3 is fixedly passed through the surface of the flange hydraulic column 2, a hydraulic cylinder 4 is fixedly installed on the surface of the flanging machine 1, and a clamping device for clamping and fixing the air spring is provided at the output end of the hydraulic cylinder 4. The clamping device includes a placement table 51, the placement table 51 is fixedly installed at the output end of the hydraulic cylinder 4, a sliding table 52 is slidably installed on the inner wall of the flanging machine 1, and a T-shaped plate 53 is fixedly installed on the circumferential surface of the placement table 51. The surface of the flanging machine 1 rotates A reciprocating screw rod 54 is installed, and a gear plate 55 is fixedly installed on the end of the reciprocating screw rod 54 away from the flanging machine 1. A reciprocating screw rod 2 56 is rotated and penetrated on the surface of the sliding table 52, and a gear plate 2 57 is fixedly installed on the end of the reciprocating screw rod 2 56 close to the gear plate 55. A clamping rod 58 is fixedly installed on the bottom of the sliding table 52, and a telescopic elastic rod 59 is fixedly installed on the surface of the clamping rod 58. A limiting clamping plate 510 is slidably installed on the surface of the flanging machine 1, and a clamping plate 511 is fixedly penetrated on the surface of the sliding table 52. The movement of the sliding table 52 drives the clamping plate 511 to move, and then the clamping plate 511 contacts and clamps the air bag under the action of the sliding table 52.

[0028] In some examples, the air supply pipe 3 is fixed through the surface of the flanging machine 1, an opening is opened on the surface of the placement table 51, the T-shaped plate 53 is slidably connected to the circumferential surface of the reciprocating screw rod 54, the T-shaped plate 53 and the reciprocating screw rod 54 are connected by threads, and the T-shaped plate 53 moves downward to drive the reciprocating screw rod 54 to rotate.

[0029] The reciprocating screw rod 2 56 is engaged with the toothed disc 2 57, the free end of the telescopic elastic rod 1 59 is fixedly connected to the limit clamping plate 510, the reciprocating screw rod 2 56 and the sliding table 52 are connected by a thread, and the reciprocating screw rod 2 56 and the sliding table 52 are connected by a thread. The rotation of the reciprocating screw rod 2 56 drives the sliding table 52 to move toward the placement table 51, and at the same time, the movement of the sliding table 52 drives the clamping plate 511 to move.

[0030] For example, Figures 1 to 7 As shown, the staff places the air bag on the surface of the placement table 51, and the staff pre-fills the air bag with some gas, and then starts the hydraulic cylinder 4. The output end of the hydraulic cylinder 4 moves downward to drive the placement table 51 to move, and at the same time, the placement table 51 moves downward to drive the T-shaped plate 53 to move. Because the T-shaped plate 53 is connected to the reciprocating screw rod 1 54 through a threaded connection, the T-shaped plate 53 moves downward to drive the reciprocating screw rod 1 54 to rotate, and at the same time, the rotation of the reciprocating screw rod 1 54 drives the gear plate 1 55 to rotate. Because the gear plate 1 55 is engaged with the gear plate 2 57, the rotation of the gear plate 1 55 drives the gear plate 2 57 to rotate, and at the same time, When the gear plate 2 57 rotates, the reciprocating screw rod 2 56 rotates. Since the reciprocating screw rod 2 56 is connected to the sliding table 52 by a threaded connection, the rotation of the reciprocating screw rod 2 56 drives the sliding table 52 to move toward the placement table 51. At the same time, the movement of the sliding table 52 drives the clamping plate 511 to move. Then, the clamping plate 511 contacts and clamps the air bag under the action of the sliding table 52, thereby achieving a fixed clamping effect on the air spring, improving the stability and reliability of the air bag in the subsequent flanging process, further improving the flanging effect and yield rate, and providing a stable operating basis for the subsequent flanging process.

[0031] When the sliding platform 52 moves toward the placement platform 51 under the action of the reciprocating screw rod 2 56, it drives the clamping rod 58 to move, and the movement of the clamping rod 58 drives the telescopic elastic rod 1 59 to move. At the same time, the movement of the telescopic elastic rod 1 59 drives the limiting clamping plate 510 to move. Subsequently, the limiting clamping plate 510 moves toward the placement platform 51 under the action of the telescopic elastic rod 1 59 until it contacts the circumferential surface of the air spring. The clamping rod 58 adapts to the shape change of the air spring inflation through the elastic deformation of the free end of the telescopic elastic rod 1 59, thereby limiting the air spring and avoiding the hard extrusion damage to the airbag surface caused by the traditional rigid limit. At the same time, it ensures that the airbag is always in the inflation process. It is finally in the preset position, which improves the limit accuracy, reduces the flange offset or wrinkles caused by deformation, and ensures the consistency of the flange quality. After the air bag is clamped and fixed, the flange hydraulic column 2 is started to move downward. The movement of the flange hydraulic column 2 drives the flange installed at its bottom to move until it contacts the top of the air bag. Then the flange hydraulic column 2 continues to move downward to squeeze the air bag. At this time, the air bag is flanged under the action of the flange so that it can enter the groove of the flange to be locked. At this time, the flange hydraulic column 2 pumps gas into the interior of the air bag until it is expanded, and then drives the clamping plate 511 to continue to move toward the air bag for detection.

[0032] like Figures 1 to 7 As shown, it shows another embodiment of the present invention, the circumferential surface of the reciprocating screw rod 2 56 is provided with a vibration device for shaking off the dust on the surface of the air spring, the vibration device includes an eccentric wheel 61, the eccentric wheel 61 is fixedly mounted on the circumferential surface of the reciprocating screw rod 2 56, the surface of the flanging machine 1 is slidably penetrated by a knocking rod 62, the surface of the flanging machine 1 is fixedly mounted with a telescopic elastic rod 2 63, the circumferential surface of the knocking rod 62 is rotated and penetrated by a reciprocating screw rod 3 64, the surface of the flanging machine 1 is fixedly mounted with a limiting rod 65, the circumferential surface of the reciprocating screw rod 3 64 is slidably mounted with a scraper 66, the rotation of the reciprocating screw rod 3 64 drives the scraper 66 to move toward the direction close to the eccentric wheel 61, the scraper 66 moves to clean the dust or impurities on the top of the air bag, and the surface of the limiting rod 65 is fixedly penetrated by a fixed plate 67. In some examples, an arc surface 1 is provided at one end of the knocking rod 62 close to the T-shaped plate 53 for generating vibration by colliding with the surface of the T-shaped plate 53. The free end of the telescopic elastic rod 2 63 is fixedly connected to the surface of the knocking rod 62. A transmission belt is connected between the reciprocating screw rod 3 64 and the reciprocating screw rod 2 56. When the reciprocating screw rod 2 56 rotates under the action of the toothed disc 2 57, the transmission belt is driven to rotate, and the rotation of the transmission belt drives the reciprocating screw rod 3 64 to rotate.

[0033] Scraper 66 is threadedly connected to reciprocating screw rod 3 64. Scraper 66 is slidably connected to the circumference of fixed plate 67. A spring is provided between limiting rod 65 and scraper 66 for reset. Scraper 66 is threadedly connected to reciprocating screw rod 3 64. Rotation of reciprocating screw rod 3 64 drives scraper 66 toward eccentric wheel 61.

[0034] The surface of the scraper 66 is provided with a processing device for performing corresponding operations based on whether it meets the standards. The processing device includes a tooth plate 71, which is fixedly mounted on the surface of the scraper 66. A fixed rod 72 is rotatably mounted on the surface of the flanging machine 1. A gear 73 is fixedly mounted on the circumferential surface of the fixed rod 72. A marking plate 74 is fixedly mounted on the circumferential surface of the fixed rod 72. A telescopic rod 75 is fixedly penetrated by the surface of the flanging machine 1. A push plate 76 is fixedly mounted on the free end of the telescopic rod 75. A linkage rod 77 is fixedly mounted on the output end of the hydraulic cylinder 4. The movement of the linkage rod 77 drives the linkage rod 77 at the end away from the output end of the hydraulic cylinder 4 to rotate.

[0035] The gear 73 is engaged with the tooth plate 71 , the shape of the marking plate 74 is set to be arc-shaped, the linkage rod 77 is rotatably connected to the free end of the telescopic rod 75 , and the rotation of the linkage rod 77 drives the free end of the telescopic rod 75 to move toward the placement platform 51 .

[0036] For example, Figures 1 to 7 As shown, the reciprocating screw rod 2 56 rotates under the action of the gear plate 2 57, driving the eccentric wheel 61 to rotate. The eccentric wheel 61 rotates, contacts and squeezes the knocking rod 62 to move downward, and the knocking rod 62 moves, contacts and collides with the surface of the T-shaped plate 53 to generate vibration. At this time, the vibration of the T-shaped plate 53 transmits the vibration to the air bag to shake off the dust accumulated on the surface of the air bag, and foreign matter that affects the installation of the flange can be removed in advance, avoiding impurities sandwiched between the air bag and the flange groove, resulting in sealing failure or decreased structural strength, thereby improving the sealing and service life of the product from the source.

[0037] When the reciprocating screw rod 2 56 rotates under the action of the toothed disc 2 57, it drives the transmission belt to rotate, and the rotation of the transmission belt drives the reciprocating screw rod 3 64 to rotate. Since the scraper 66 and the reciprocating screw rod 3 64 are connected by a thread, the rotation of the reciprocating screw rod 3 64 drives the scraper 66 to move toward the eccentric wheel 61. The scraper 66 moves to clean the dust or impurities on the top of the air bag, further improving the cleaning effect of the air bag surface, and further removing the fine impurities or dispersed dust remaining after vibration, forming a vibration loosening and contact cleaning cleaning, which significantly improves the cleanliness of the air bag surface, reduces the pollution risk during the installation process, and improves the product yield.

[0038] When the air bag detection result meets the standard, the hydraulic cylinder 4 is started, and the output end of the hydraulic cylinder 4 moves upward, driving the scraper 66 to move away from the placement table 51. The movement of the scraper 66 drives the gear plate 71 to move. Because the gear plate 71 is engaged with the gear 73, the gear plate 71 moves in the direction away from the placement table 51, driving the gear 73 to rotate. At the same time, the rotation of the gear 73 drives the fixed rod 72 to rotate, and the rotation of the fixed rod 72 drives the marking plate 74 to rotate counterclockwise. The marking plate 74 rotates to mark the air bag that meets the standard, thereby realizing permanent marking of qualified air bags, ensuring uniform marking position and accurate information, facilitating subsequent traceability and quality control, and at the same time improving production efficiency, reducing problems of human omission or mislabeling, and eliminating the need for manual intervention, thereby improving the accuracy of marking.

[0039] When the air bag passes the inspection, the hydraulic cylinder 4 is started, and the output end of the hydraulic cylinder 4 moves downward, driving the linkage rod 77 to move downward. At the same time, the movement of the linkage rod 77 drives the linkage rod 77 at the end away from the output end of the hydraulic cylinder 4 to rotate. The rotation of the linkage rod 77 drives the free end of the telescopic rod 75 to move toward the placement table 51. The free end of the placement table 51 moves until the air bag is pushed out through the opening opened on the surface of the placement table 51. At this time, the effect of corresponding processing of the air bag after the inspection is achieved. This function realizes the automatic linkage between the inspection results and the sorting action, avoids unqualified products from flowing into the next process, and at the same time reduces the labor intensity of manual sorting, improves the intelligence level of the production line, and ensures the stability and consistency of product quality.

The output end of the hydraulic cylinder (4) moves downward to drive the placement table (51) to move. At the same time, the placement table (51) moves downward to drive the T-shaped plate (53) to move. The T-shaped plate (53) moves downward to drive the reciprocating screw rod (54) to rotate; Step 2: The reciprocating screw rod 1 (54) rotates to drive the gear plate 1 (55) to rotate. Since the gear plate 1 (55) is engaged with the gear plate 2 (57), the rotation of the gear plate 1 (55) drives the gear plate 2 (57) to rotate. At the same time, the rotation of the gear plate 2 (57) drives the reciprocating screw rod 2 (56) to rotate. Step 3: The reciprocating screw rod 2 (56) rotates to drive the sliding table (52) to move toward the placement table (51), and at the same time, the movement of the sliding table (52) drives the clamping plate (511) to move, and then the clamping plate (511) contacts and clamps the air bag under the action of the sliding table (52); Step 4: The sliding table (52) moves toward the placement table (51) under the action of the reciprocating screw rod 2 (56), driving the clamping rod (58) to move. The movement of the clamping rod (58) drives the telescopic elastic rod 1 (59) to move. At the same time, the movement of the telescopic elastic rod 1 (59) drives the limiting clamp (510) to move. Subsequently, the limiting clamp (510) moves toward the placement table (51) under the action of the telescopic elastic rod 1 (59) until it contacts the circumferential surface of the air spring. The clamping rod (58) device adapts to the shape change of the air spring through the elastic deformation of the free end of the telescopic elastic rod 1 (59); Step 5: After the air bag is clamped and fixed, the flange hydraulic column (2) is started to move downward. The movement of the flange hydraulic column (2) drives the flange installed at the bottom thereof to move until it contacts the top of the air bag. Then the flange hydraulic column (2) continues to move downward to squeeze the air bag. At this time, the air bag is flanged under the action of the flange so as to enter the groove of the flange to achieve locking. At this time, the flange hydraulic column (2) pumps gas into the interior of the air bag until it is fully expanded, and then drives the clamping plate (511) to continue to move in the direction close to the air bag to detect it.
