Flexible lossless meshing assembly mechanism for gears

Technical Field

The utility model belongs to the technical field of automatic assembly, and relates to automatic meshing assembly equipment for two gears.

Background

The gear meshing automatic assembly adopts the mode that one gear is placed statically, and the other gear is placed into the static gear from top to bottom. The feeding postures of the gears on the assembly line are arbitrary, and the assembly in the mode needs to guide the relative positions of the two gears before the gears above the gears are assembled, so that two groups of gear posture adjusting mechanisms need to be added, and the cost of the whole equipment is high. Moreover, even under the condition that the relative positions of the two gears are aligned, the upper gear is very easily influenced by the vibration of the equipment in the descending process, and the surfaces of the two gears are scratched.

The servo rotary motor 40 is fixedly connected to the floating table 30, and the servo rotary motor 40 drives the pneumatic holding jaw 50 for holding the gear to rotate. If the relative position of the upper gear and the lower gear is deviated, the bottom surface of the upper gear is contacted with the top surface of the lower gear, the floating platform 30 is pushed upwards, the sensor 70 detects the height change between the floating platform 30 and the base platform 20, the servo linear motor stops immediately, the upper gear stops descending, the servo rotary motor 40 drives the upper gear to rotate to adjust the angle, if the positions of the upper gear and the lower gear are aligned, the thrust applied to the floating platform 30 disappears, the floating platform 30 descends immediately under the action of the spring force, and the servo linear motor 10 drives the upper gear to continue descending until the assembly of the two gears is completed.
