Description

Technical Field

[0001] The utility model relates to the technical field of chain shaft sleeve assembly, in particular to a chain shaft sleeve pressing device. Background Art

[0002] Chains are generally metal links or rings that have mechanical transmission and traction functions. They are generally composed of multiple chain plates and sleeves. Sleeves need to be inserted at the connections between the multiple chain plates for fixation. When assembling and installing, a press-in device is generally required to press the sleeves into the through holes on the two chain plates to combine the multiple chain plates.

[0003] Existing pressing equipment generally provides pressure through a power mechanism to press the sleeve onto the chain plate. However, during the production process of the chain, the chain plate is generally not specially lubricated. During the pressing process, there is a large friction between the holes on the chain plate and the sleeve, which causes damage to the chain plate during pressing and affects the quality of the chain. For this reason, we provide a chain sleeve pressing device to solve the above problems. Utility Model Content

[0016] 1. The utility model provides components such as a rebound mechanism and an extrusion box, and the cylinder is extended to drive the extrusion box.
