Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment equipment, in particular to a connecting rod assembly device. Background Art

[0002] The structure of the sorting machine of the construction waste treatment process line contains multiple sets of elastic connecting rods. The elastic connecting rods are assembled from elastic hinges and connecting rod sleeves. The elastic hinges include inner rigid hinges, outer rigid hinges and an elastomer sandwiched between the inner rigid hinges and the outer rigid hinges. The elastic hinges need to be installed in the connecting rod sleeve and ensure that they are in the middle of the sleeve axis and at the same distance from the two end faces of the sleeve. Since the outer diameter of the elastic hinge is slightly larger than the inner diameter of the rigid sleeve, it is difficult to put it in directly and needs to be deformed by external strong compression before it can be put in. At present, there is no special device for assembling elastic connecting rods in the factory, and it only relies on manual strong assembly, which makes it difficult to ensure the assembly quality of the elastic connecting rods, affecting the yield rate and later service life, and is very time-consuming and labor-intensive.

[0003] Authorized patent number CN115781236A discloses an elastic connecting rod assembly device for garbage sorting equipment, including a base, an elastic hinge installation device and two supports are provided on the base, a connecting rod sleeve includes a connecting rod flange, and rigid sleeves are fixedly installed at the left and right ends of the connecting rod flange, and the connecting rod sleeve is placed on the two supports; the elastic hinge installation device includes a lifting drive device and a clamping device. The present invention has a simple structure and is easy to operate, and has the beneficial effects of reducing labor intensity, improving assembly efficiency, improving installation accuracy, ensuring installation quality, reducing damage to elastic hinges during assembly, improving the yield rate, extending the service life of the elastic connecting rod, and reducing the maintenance frequency.

[0004] However, the above device places a rigid sleeve on a support. When the support is moved, it is difficult to ensure the stability of the rigid sleeve, especially when the clamping device applies pressure to the rigid sleeve and the elastic hinge, it is easy to be misplaced and difficult to maintain stability. In this regard, we design a connecting rod assembly device. Utility Model Content
