Problems solved by technology
Because the axis of the steel hinge pin is not parallel to the axis of the manipulator, and the load balance of the manipulator is adjusted in advance according to the weight of the door, there is no other external lifting force to overcome the extra friction generated by the non-parallelism, so the existing manipulator cannot move the door. removed from the body

The invention discloses an air path control device of a vehicle door dismounting and mounting manipulator. The device mainly comprises a loading channel and a pressurization control channel composed of a pressurization manual control valve, an additional auxiliary pressure reducing valve and an additional auxiliary pressure reducing control valve. When the vehicle door dismounting and mounting manipulator is used for dismounting a new vehicle type vehicle door adopting a profile steel hinge, the pressurization manual control valve is pressed down, the additional auxiliary pressure reducing control valve is switched on, airflow from an air source is added to the control end of a main pressure reducing valve through the additional auxiliary pressure reducing valve, and therefore a loading air cylinder is pressurized and inflated, the load lifting force of the vehicle door dismounting and mounting manipulator is improved, additional friction force generated due to the fact that the axialdirection of a profile steel hinge pin shaft is not parallel to the axial direction of the vehicle door dismounting and mounting manipulator can be overcome, and the profile steel hinge pin shaft is pulled out and the vehicle door is dismounted. The air path control device solves the problem that an existing air path control device of the vehicle door dismounting and mounting manipulator is only suitable for dismounting an old vehicle type vehicle door adopting a stamping hinge and is not suitable for dismounting the new vehicle type vehicle door adopting the profile steel hinge.
Description
technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a gas path control device for a door dismounting manipulator. Background technique [0002] The disassembly and assembly of automobile doors is generally completed by manipulators. The door hinge structure of the old model in production is a stamping hinge, which is a four-point bolt connection structure. After the hinge bolts are disassembled, the manipulator only needs to realize the load balance of the weight of each door (the lifting force generated by the driving cylinder is equal to the load weight), and then the door can be easily removed from the vehicle body. The doors of new models generally adopt the form of steel hinges, and the hinge pins of the steel hinges must be pulled out to remove the doors. Because the axis of the steel hinge pin is not parallel to the axis of the manipulator, and the load balance of the manipulator is adjusted i...
