Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing equipment, in particular to a coupling assembly process equipment for agricultural machinery. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. They rotate together during the transmission of motion and power and do not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads, thus playing the role of overload protection.

[0003] In the high-speed and heavy-load power transmission of agricultural machinery and equipment, the coupling also has the functions of buffering, vibration reduction and improving the dynamic performance of the shaft system. The drivers of agricultural machinery and equipment need to be connected to the equipment through couplings for use, and the elastic sleeve pin coupling is widely used. During the production of the elastic sleeve pin coupling, multiple pins and elastic sleeves need to be installed between the active end connecting seat and the driven end connecting seat through nuts. The assembly steps are cumbersome and require a large amount of manpower for assembly. Since the elastic sleeve is elastic, when the driven end connecting seat and the active end connecting seat are closed and installed, the elasticity will press the driven end connecting seat against the manual tightening nut for assembly and fixing. It is easy to have uneven torque, resulting in loose installation. Repeated debugging is required to complete the correct installation, which greatly reduces the assembly efficiency.

[0004] Therefore, it is particularly important to design a coupling assembly process equipment for agricultural machinery to solve the above-mentioned defects. Utility Model Content

[0032] In this embodiment, the implementation scenario is specifically as follows: when assembling the coupling body 7, the bottom end of the pin 703 is placed in the positioning hole 802 to complete the positioning, and then the active end connecting seat 701 is aligned with the top of the pin 703 and lowered so that its bottom end enters the inner side of the positioning groove 801 to complete the positioning, and then the elastic sleeve 704 and the driven end connecting seat 702 are assembled in turn.
