Description

Technical Field

[0001] The utility model relates to the technical field of hinge assembly, in particular to a damping hinge assembly device which can automatically assemble rivets for hinges. Background Art

[0002] A damping hinge is usually made of two steel sheets assembled by a rivet on each side, and then working in opposite directions to produce a damping effect. The damping hinge is a hardware part with a simple structure and a wide range of applications. In the prior art, damping hinges are mostly assembled manually, which is inefficient and cannot guarantee assembly accuracy, and is likely to affect the damping effect of the hinge, causing the hinge to fail to function properly.

[0003] At present, most hinge assembly devices on the market generally use a cylinder to drive the ejector to insert the pin from one side of the hinge, which will result in the need to first press in the left-end rivet and then turn the product over and press in the right-end rivet for production. For example, the Chinese utility model patent with patent announcement number CN205114419U discloses a pin insertion device for a hinge processing machine, which includes: a feeding device, a loading device and an ejector device. The loading device includes a plurality of loading boxes that can be used interchangeably, each of which can be moved to the receiving position below the through hole to receive the dropped pins and move to the feeding position after being filled; the ejector device includes an ejector installed behind the feeding position to push the pins in the loading box out and insert them into the middle of the hinge, and the ejector is connected to the cylinder that controls its movement. Its pins are automatically fed, and the cylinder pushes to realize the automatic insertion of the pins in the middle of the hinge.

[0004] However, the pin insertion device of the existing hinge processing machine has the following disadvantages due to its structural characteristics:

[0005] The pin insertion work in this scheme is carried out from one side of the hinge by driving the ejector pin with an air cylinder. However, for the hinge piece assembled with left and right double rivets, it is impossible to realize the left and right rivets moving towards each other and pressing them into the hinge piece at one time. In addition, the pin insertion method of the ejector pin pushing the hinge piece in one direction is prone to excessive pushing, resulting in errors, affecting the quality of the hinge piece, and there are also problems such as waste of working hours.

[0033] The driving assembly 3 includes a push block 32, a power element 30 for driving the push block 32 to move, and a connecting rod 31 arranged between the power element 30 and the push block 32; the push block 32 is provided with a first push arm 321 and a second push arm 322 for driving the first assembly part 21 and the second assembly part 22 to move synchronously toward each other, wherein the first push arm 321 and the second push arm 322 are respectively in contact with the first assembly part 21 and the second assembly part 22; the push block 32 is also provided with a third push arm 323, the front end of which is in contact with the positioning member 23. Since the hinge 90 moves toward each other from both sides, that is, when the power element 30 pushes the push block 32 forward through the connecting rod 31, the first push arm 321 drives the first assembly part 21 to move, and the second push arm 322 drives the second assembly part 22 to move, that is, the first assembly part 21 and the second assembly part 22 move toward each other and drive the first rivet and the second rivet to be assembled in the hinge 90 respectively.

[0034] In this embodiment, the first pushing arm 321 and the second pushing arm 322 can respectively push the first assembly part 21 and the second assembly part 22 to generate displacement when they move forward, which is achieved by the cooperation between the inclined surfaces. Specifically, the front end of the first pushing arm 321 is respectively formed with a first inclined surface 321A, and the front end of the second pushing arm 322 is respectively formed with a second inclined surface 322A.
