On the electric drive assembly production line, in order to efficiently complete the assembly operation of the reduction gearbox, it is often necessary to simultaneously grab multiple gears and assemble them onto the electric drive assembly at one time. This makes the assembly process have high position accuracy requirements for the gear shaft system in the assembly plane, and the assembled components need to have a certain elastic floating ability in both the assembly plane and the direction perpendicular to the assembly plane, so that the gear shaft system and the electric drive main body can perform adaptive meshing pairing when the internal and external spline shafts are aligned. In the traditional assembly process, the electric drive assembly is often assembled manually in multiple processes, with low assembly efficiency, high labor intensity, and it is easy to cause the situation of workpiece collision during the assembly process.

[0049] Reference Figures 1 - 17, the working principle of the present utility model is as follows: During actual use, the shaft system is placed on the input tray 5 and transported to the designated position by the input conveyor line 4. The industrial robot 3 carries the shaft system fixture 1 and inserts the shaft system into each positioning guide block from above the shaft system simultaneously. Each jaw cylinder drives the jaws to grip the shaft system. Then, the industrial robot 3 drives the shaft system fixture 1 with the shaft system to move to the shaft system assembly table 2 and inserts the shaft system into each positioning guide block. The jaws on the shaft system fixture 1 are driven by each jaw cylinder to release, and the industrial robot 3 leaves with the shaft system fixture 1. The second cylinder 2-19 extends to drive the lifting rod 2-17 to move upward with the ejector head 2-22 and squeeze the expansion head 2-24 to make the expansion head 2-24 expand and tightly adhere to the inner wall of the shaft system. The reduction motor 2-28 rotates, successively driving the small gear 2-12, large gear 2-13, pin 2-18, rotating shaft 2-14, ejector head 2-22, expansion head 2-24, and the shaft system to rotate. At the same time, the first cylinder 2-9 drives the adapter plate four 2-8 to move the non-rotating shaft system along the guide rail two 2-7 towards the rotating shaft system. When the two shaft systems come into contact and one shaft system's tooth top is aligned with the tooth root of the other shaft system through rotation, the shaft systems enter into meshing. The shaft systems continue to rotate and approach until they are fully meshed. At the same time, the cylinder two 2-29 drives the rack 2-31 to slide within the mounting seat 2-30 and mesh with another set of large gears 2-13. Subsequently, this large gear 2-13 drives a set of the same rotating unit to complete the meshing of another set of shaft systems placed thereon. The reduction motor 2-28 and the cylinder two 2-29 stop operating. The second cylinder 2-19 retracts, the expansion head 2-24 contracts and disengages from the inner wall of the shaft system. If the shaft systems have not been fully meshed at this time, the rodless cylinder 2-4 will move the shaft system to the manual station. The operator rotates and moves the shaft system until meshing is completed. The rodless cylinder 2-4 brings the shaft system back to the automatic station. The industrial robot 3 uses the shaft system fixture 1 to insert the shaft system with each positioning guide block three 1-19 installed on each compensation unit 1-22. Each jaw cylinder three 1-21 drives each jaw four 1-24 to grip the shaft system. The industrial robot 3 drives the shaft system fixture 1 to move the shaft system to the output tray 7 and insert it. The cylinders on the shaft system assembly table 2 return to their initial positions. Each jaw cylinder three 1-21 drives each jaw four 1-24 to release the shaft system. The industrial robot 3 leaves with the shaft system fixture 1 and enters the next working cycle.
