Problems solved by technology
The disadvantage of this solution is that the push speed cannot be adjusted, so that it is impossible to simulate the door closing speed in actual use of the vehicle; at the same time, the rubber block is used to contact the car door immediately to form a collision, so that the force of each collision will be generated according to the actual contact angle. There is also the possibility of inaccurate detection

The invention relates to the automobile manufacturing equipment technology field and especially relates to a vehicle door quantitative force application device used for automobile manufacturing and usage method thereof. The device comprises a main frame, an auxiliary frame, a constant force thruster, a controller, an air pump and a suction disc. The auxiliary frame can be movably arranged on the front side of the main frame through a power avoidance device. The front side of the auxiliary frame is provided with a hand-operated type lifting mechanism. One end of the constant force thruster is connected to the hand-operated type lifting mechanism in a transmission connection mode. The other end of the constant force thruster is provided with a walking support. The suction disc is connected to an output rod of the constant force thruster through a universal joint. The constant force thruster comprises a hydraulic rod and a frequency conversion oil pump. The air pump and the frequency conversion oil pump are arranged on the external portion of the main frame. The upper portion of the hydraulic rod is provided with a detachment sensor which can be rotated and adjusted. The detachment sensor can carry out synchronous vertical movement with the hydraulic rod through the hand-operated type lifting mechanism. The detachment sensor and the controller are electrically connected. In the invention, accuracy of vehicle door closing detection can be greatly increased.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing equipment, in particular to a device for quantitatively applying force to a door in automobile manufacturing and a method for using the same. Background technique [0002] At present, in the field of automobile manufacturing, the comfort of the car door is an important factor in evaluating the car. The minimum force required to close the entire door is a criterion used to evaluate the quality of the car. In the quality control of automobiles, the difficulty of the door is a very prominent problem. In many economical cars, most of the doors cannot be opened and closed very well and easily. Every time the car owner closes the door, he has to push hard, which is laborious and insecure. In recent years, major domestic OEMs have used door closing speed meters to quantitatively measure and analyze the door closing in the trial production stage of prototype vehicles. This method has t...
