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 technical field of automobile manufacturing equipment, and particularly relates to an automobile door quantitative force application device applied to automobile manufacturing and a using method thereof. The automobile door quantitative force application device comprises a main rack, an auxiliary rack, a constant-force propeller, a controller, a gas pump and a sucker;the auxiliary rack can be movably arranged at the front side of the main rack by a power avoidance device; a hand-operated lifting mechanism is mounted at the front side of the auxiliary rack; one endof the constant-force propeller is in transmission connection with the hand-operated lifting mechanism; a traveling bracket is mounted at the other end of the constant-force propeller; the sucker isconnected with an output rod of the constant-force propeller by a universal joint; the constant-force propeller comprises a hydraulic rod and a variable-frequency oil pump; both the gas pump and the variable-frequency oil pump are mounted outside the main rack; a separation sensor which can be rotationally regulated is also arranged above the hydraulic rod; the separation sensor can synchronouslyand vertically move with the hydraulic rod by the means of the hand-operated lifting mechanism; and the separation sensor is electrically connected with the controller. According to the invention, accuracy of detecting closeness of an automobile door can be greatly improved.
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...
