Embodiment Construction

[0032] In the prior art, a suction cup leveling device is usually used to position the vehicle door. However, the suction cup leveling device is prone to failure, for example, the air hole in the suction cup adjustment device is easy to block, the suction cup rubber is easily deformed and cannot be sealed, etc., resulting in inconsistent adsorption force of the front suction cup and the rear suction cup, so that the surface difference block cannot be aligned with the front door at the same time. It fits with the rear door, so that there is a large surface difference between the front door and the rear door, and it is difficult to meet the assembly accuracy requirements of the door.

[0033] In view of this, an embodiment of the present invention provides a door positioning device, the end of the tension rod can be limited in the limit groove of the body-in-white, and the body-in-white is clamped by locking the tension rod with the locking assembly. Between the tension rod and ...

Abstract

The invention provides a vehicle door positioning device, and relates to the technical field of automobiles. The vehicle door positioning device is used for solving the technical problem that in the vehicle door installing process, a large surface difference exists between a front vehicle door and a rear vehicle door, and the vehicle door assembly precision requirement is difficult to meet. The vehicle door positioning device comprises a locking mechanism and an adjusting mechanism, a body-in-white is clamped between a tensioning rod and a locking base by locking the tensioning rod through a locking assembly, a second clamping rod is driven to rotate through a connecting assembly so that the second clamping rod can be coaxial with a first clamping rod, the second clamping rod is locked to the position coaxial with the first clamping rod through an anti-disengaging assembly, then at least one of the second clamping rod and the first clamping rod is made to move in the axial direction of the first clamping rod, the vehicle door is fixed in the clamping space, the vehicle door is prevented from sliding to affect the assembling precision so that the front vehicle door and the rear vehicle door can be positioned correspondingly, and the front vehicle door and the rear vehicle door can both meet the assembling precision requirement.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle door positioning device. Background technique [0002] During the assembly process of the automobile body-in-white, the door of the automobile is usually hinged with the automobile body-in-white through hinges. In order to meet the lightweight design of automobiles, aluminum doors have become the choice of more and more car companies. When installing a car door, a suction cup leveling device is usually used to position the door. [0003] The suction cup leveling device includes a front suction cup, a rear suction cup and a surface difference block between the front suction cup and the rear suction cup. When positioning the door, the front suction cup is usually used to absorb the front door and the rear suction cup is used to absorb the rear door so that the surface difference The blocks fit the front door and the rear door respectively. [0004] However, the suc...
