Abstract: When manually assembling a car opening door lock puller assembly, it requires 2 people
to work closely together to complete it. In order to improve the production efficiency, a semi-automatic
machine clamping equipment is designed on the basis of manual assembly action. The machine fixture
is equipped with a single cylinder piston pushing and resetting mechanism to complete the pushing and
resetting movement of the connecting rod, and a double cylinder piston clamping and resetting mechanism
to complete the clamping and resetting movement of the pendulum torsion spring. In manual operation, it is
necessary to put the puller into the equipment for positioning, and it is also necessary to put the torsion spring
into the cylinder of the pendulum block, compress the torsion spring and put the pendulum block and torsion
spring into the puller between the two ends of the cams which are 33.3 mm apart, and the right end of the
torsion spring needs to be inserted into the corresponding hole of the puller. The semi-automatic machine
clamping equipment saves manpower, reduces the labour intensity of workers, improves the production
efficiency and assembly quality, and lays the foundation for the design and manufacture of the subsequent
fully automatic equipment.
Key words: handle assembly; manual assembly; machine clamping equipment; push reset mechanism;
