Description

Technical Field

[0002] A torque damper, also known as a torque damper, is generally used to connect the driving source and the driven source. Its main function is to protect the driving source by transmitting torque in the form of slipping when the driven source is overloaded. When the slip ends and the overload disappears, the transmission process is resumed.

[0003] During the manufacturing and installation process of the torque limiting vibration damper, there is a transmission mechanism inside. The important component of the transmission mechanism includes the friction plate. The friction plate needs to be installed on both sides of the corrugated plate and connected to the shock absorbing mechanism. When the friction plate and the corrugated plate are installed, multiple rivet interfaces are provided on them in a ring shape, and rivets are needed to connect the friction plate and the corrugated plate.

[0004] During the operation of the specific embodiment, the inventors found the following defects:

[0005] Since the friction plates are arranged in a ring on both sides of the corrugated plate, a riveting machine is required to rivet the friction plates one by one. After each riveting, the plates need to be rotated at a preset angle and riveted again. The riveting efficiency is low, and manual riveting operations are prone to cause damage to operators.

[0006] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

Then, the first rotating motor will drive the riveting support plate 4 on this side to rotate inward, rotate to the bottom of the hydraulic riveting mechanism 9, and the riveting support plate on the opposite side will rotate inward. The friction sheet and the corrugated sheet on the disk 4 are riveted at this time. After the operator takes the material, he places the new corrugated sheet and the friction sheet to be riveted on the rotating riveting support disk 4 again, waiting for the next round of operation. At the same time, the second workbench 5 loads the rivets. The loading track 8 can be manually loaded, that is, the rivets are pushed into the loading track 8 manually, or automatically loaded, that is, the loading track 8 is connected to the rivet loading vibration disk for loading. The vibration disk is an existing technology and will not be described in detail here.

[0036] A riveting groove 41 is provided in a ring shape on the top of the riveting support plate 4, and a positioning pin 42 is provided in a ring shape inside the riveting groove 41. The riveting groove 41 is adapted to the rivet to facilitate subsequent riveting operations. The positioning pin 42 is adapted to the hole on the inner side of the corrugated sheet to be processed. When loading the material, the operator only needs to align the hole on the corrugated sheet with the positioning pin 42.

The layout shape of the rivet placement grooves 62 corresponds one-to-one to the holes to be riveted on the corrugated sheet. During loading, the rivet will enter the rivet placement grooves 62 through the loading track 8. After entering a rivet, the second rotating motor drives the rotating loading disc 7 to rotate a preset angle so that the second rivet placement groove 62 is aligned with the loading track 8 for loading.

The rivet moving mechanism 10 can take out the rivets loaded on the bottom rotating loading tray 7 as a whole and send them into the riveting support tray 4. When the rivet placement grooves 62 of the rotating loading tray 7 are all put into the rivets, the rotating screw rod drives the moving plate to move to the top of the rotating loading tray 7, and then the lifting and transportation mechanism 104 will descend, and the rivets on the bottom rotating loading tray 7 will be adsorbed, and then lifted by the lifting and transportation mechanism 104. The rotating screw rod drives the moving plate to the top of the riveting support tray 4 again, and the lifting and transportation mechanism 104 descends to put the rivets into the corresponding position of the corrugated sheet and then lifts and resets, waiting for the next round of transportation operation.
