Description

Technical Field

[0001] The utility model relates to the technical field of riveting equipment, in particular to a riveting equipment for automobile parts. Background Art

[0002] During the riveting process of automobile parts, the parts need to be placed in the corresponding tooling, and then riveted by a riveting head. Before riveting two relatively large concave plates, the two concave plates need to be placed in the corresponding tooling first. The vertical rods on the tooling are inserted into the through holes of the concave plates to limit the concave plates. After riveting, it can be directly taken out upwards. Although this method makes the placement and removal of the concave plates convenient, the concave plates are relatively large. After being limited horizontally, they are prone to shift longitudinally before the riveting head moves down for riveting, which is likely to cause the riveting position to shift. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problem that the riveting head is prone to shift longitudinally before moving down for riveting, which is likely to cause the riveting position to shift as mentioned in the above background art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A riveting equipment for automobile parts, comprising: a workbench, a pressing component and a top plate. An installation seat moving longitudinally is arranged on the upper side of the workbench, and a riveting head is installed on the installation seat; the pressing component includes two symmetrical pressing plates. A connecting plate is installed on the installation seat, and the pressing plate is connected with the connecting plate through an elastic member. The height of the pressing plate is lower than that of the riveting head; the top plate is arranged on the lower side of the concave plate, and the top plate makes the two riveted concave plates have a rising and falling stroke through longitudinal reciprocating movement.

[0006] Preferably, the elastic member includes a rod body slidably connected to the connecting plate. A spring is sleeved on the rod body. Two sides of the spring are respectively connected with the rod body and the connecting plate, and the lower end of the rod body is connected with the pressing plate.

[0007] Preferably, an elastic detection rod is installed on the connecting plate.

[0008] Preferably, the top plate is connected with the connecting plate through a transmission mechanism.

[0009] Preferably, the transmission mechanism includes a driving rack fixed to the connecting plate and a transmission gear arranged on the workbench. A driving shaft is fixed on the transmission gear, a driving gear is connected to the driving shaft, the driving gear is meshed with a jacking rack, and the jacking rack is fixedly connected with the top plate.

[0010] Preferably, two sliding rods are fixed on the workbench, and extension plates extend out on both sides of the jacking rack and are slidably connected with the sliding rods.

[0011] Preferably, the jacking rack is located at the middle position of the top plate.

[0012] Preferably, two telescopic shock absorbers are arranged on the workbench, and the extending ends of the two telescopic shock absorbers are respectively abutted against the upper and lower sides of the extension plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Before riveting, the pressing plate presses and fixes the two concave plates from the upper side, and then cooperates with the tooling to make the concave plates stable horizontally and vertically. Moreover, after riveting is completed, it also prevents the concave plates from being lifted by the riveting head and then falling to form vibrations after just being riveted.

[0015] The elastic detection rod is used to insert into the through hole of the concave plate. If the elastic detection rod can be inserted normally, it means that the position of the concave plate is correct. If the elastic detection rod is compressed, it means that the position of the concave plate is incorrect.

[0016] The cooperation between the top plate and the transmission makes it convenient to take out the concave plate after it rises and falls, and it will not cause the rivets to be stuck on the tooling due to riveting. Moreover, through the telescopic shock absorber, the concave plate can slowly fall back, preventing the vibration of the concave plate when it falls back. Description of the Drawings

[0027] Please refer to Figures 1-4 , a riveting device for automotive parts, including: a workbench 1, a pressing component 2 and a top plate 3. There is a longitudinally movable mounting seat 4 on the upper side of the workbench 1. A riveting head 41 is installed on the mounting seat 4. The mounting seat 4 and the riveting head 41 are prior arts. The bracket supporting the mounting seat 4 in the figure is a prior art. There is a tooling 11 on the workbench 1. A plug rod inserted into the concave plate is fixed on the tooling 11. One inner wall of the tooling 11 is an arc surface, and the arc surface contacts the side arc surface of the concave plate;

[0028] The pressing component 2 includes two symmetric pressing plates 21. The two pressing plates 21 are respectively on two sides of the riveting head 41. A connecting plate 5 is installed on the mounting seat 4. The pressing plate 21 is connected to the connecting plate 5 through an elastic member 22. The height of the pressing plate 21 is lower than that of the riveting head 41. The elastic member 22 includes a rod body 221 slidably connected to the connecting plate 5. A spring 222 is sleeved on the rod body 221. Two sides of the spring 222 are respectively connected to the rod body 221 and the connecting plate 5. The lower end of the rod body 221 is connected to the pressing plate 21.

[0029] During the process of moving the riveting head 41 downward for riveting, the pressing plate 21 first contacts the upper surface of the concave plate, and then the riveting head 41 continues to move downward. The rod body 221 slides upward on the connecting plate 5 until the riveting head 41 reaches the position. Before riveting, the pressing plate 21 presses and fixes the two concave plates from the upper side, and then cooperates with the tooling 11 to make the concave plates stable horizontally and longitudinally. After riveting is completed, it also prevents the concave plates from being lifted and then falling again by the riveting head 41 after just being riveted, forming vibrations. An elastic detection rod 23 is installed on the connecting plate 5. The elastic detection rod 23 is an elastic rod in the prior art. The elastic detection rod 23 is used to insert into the through hole of the concave plate. If the elastic detection rod 23 can be inserted normally, it means that the position of the concave plate is correct. If the elastic detection rod 23 is compressed, it means that the position of the concave plate is incorrect.

[0030] The top plate 3 is arranged on the lower side of the concave plate. The top plate 3 makes the two riveted concave plates have a rising and falling stroke through longitudinal reciprocating movement. When the riveting head 41 is about to return to the highest position at the rising and falling positions of the two concave plates, at this time, the rising and falling of the two concave plates do not affect the connection. The top plate 3 makes it convenient to take out the concave plates after rising and falling, and will not cause the situation that the rivets are stuck on the tooling 11 due to riveting.

[0031] The top plate 3 is connected to the connecting plate 5 through a transmission mechanism 6. The transmission mechanism 6 includes a driving rack 61 fixed to the connecting plate 5 and a transmission gear 62 arranged on the workbench 1. Only a part of the driving rack 61 has teeth. The teeth on the driving rack 61 first engage with and then disengage from the transmission gear 62 during the upward and downward movement. A driving shaft 63 is fixed on the transmission gear 62. The driving shaft 63 is supported by the workbench 1. A driving gear 64 is connected to the driving shaft 63. The driving gear 64 is meshed with a jacking rack 65. The jacking rack 65 is located at the middle position of the top plate 3. The jacking rack 65 is fixedly connected to the top plate 3. Two sliding rods 66 are fixed on the workbench 1. Extension plates 651 extend out on both sides of the jacking rack 65 and are slidably connected to the sliding rods 66. Two telescopic shock absorbers 67 are arranged on the workbench. The extending ends of the two telescopic shock absorbers 67 respectively abut against the upper and lower sides of the extension plate 651. The telescopic shock absorbers 67 can slowly reset the top plate 3. The telescopic shock absorbers 67 are prior art and will not be described in detail.

[0032] In use, when the riveting joint 41 moves downward, before riveting, the teeth on the driving rack 61 first cause the transmission gear 62 to rotate. The transmission gear 62 causes the driving shaft 63 to rotate. The driving shaft 63 causes the jacking rack 65, the extension plate 651 and the top plate 3 to move downward. The extension plate 651 presses against the lower telescopic shock absorber 67. After the teeth on the driving rack 61 are separated from the transmission gear 62, the lower telescopic shock absorber 67 causes the jacking rack 65, the extension plate 651 and the top plate 3 to slowly reset. When the riveting is completed, the driving rack 61 rises. The teeth on the driving rack 61 cause the transmission gear 62 to rotate. The transmission gear 62 causes the driving shaft 63 to rotate. The driving shaft 63 causes the jacking rack 65, the extension plate 651 and the top plate 3 to move upward. The top plate 3 jacks up the concave plate. At the same time, the extension plate 651 presses against the upper telescopic shock absorber 67. After the teeth on the driving rack 61 are separated from the transmission gear 62, the upper telescopic shock absorber 67 causes the jacking rack 65, the extension plate 651 and the top plate 3 to slowly move downward and reset. And the concave plate moves with the top plate 3. The upper telescopic shock absorber 67 prevents the shock of the concave plate from falling back.
