Technical Field

The invention relates to the technical field of clearance surface difference adjustment, in particular to a mechanism for adjusting a clearance surface difference.

Background

As shown in figure 1, the installation positioning points of the parts are arranged on the reinforcing plate, and the appearance surfaces of the parts are matched with the sheet metal outer plate. During the manufacturing process, due to stamping of the reinforcing plate, welding between sub-assemblies, edge covering of the outer plate and size deviation accumulation, relative gaps between mounting points on the reinforcing plate and the outer door plate are floated. When the common fastening screws are used for mounting parts, the deviation cannot be compensated, the deviation exists on the appearance surface of the handle after the mounting is finished, the smooth curve modeling of the vehicle body is influenced, and the wind resistance borne by the vehicle during the running process is increased.

Chinese patent application No. CN201810689239.2 discloses an auxiliary tool for adjusting clearance surface difference of a car body, which can make the clearance surface difference of a car body component more convenient to adjust to a certain extent, and has the problems that the above tool is not suitable for eliminating the deviation when parts are installed, and cannot be used in a small space position as shown in fig. 1 because the space occupation is large.

Disclosure of Invention

The invention provides a mechanism for adjusting the difference of clearance surfaces, aiming at overcoming the technical problems that the relative clearance between the mounting point on a reinforcing plate and an outer door plate is floating, the traditional fastening screw cannot compensate the deviation, the deviation exists on the appearance surface of a handle after the installation is finished, and the smooth curve modeling of a vehicle body is influenced.

In order to achieve the above object, the present invention adopts the following technical solutions.

The utility model provides an adjust poor mechanism of clearance face, includes regulating part, mounting, locating part and base, and the base links to each other with the part of treating fixing, and regulating part and base screw thread normal running fit, mounting and locating part are located the both sides of base respectively, and the locating part links to each other with global fixed of regulating part, and the mounting can be dismantled with the regulating part and be connected, works as when mechanism's installation targets in place, locating part and reinforcing plate butt, the mounting with the part butt.

The traditional part installation operation is usually realized through the fastening cooperation of screw and nut, and the problem lies in, part installation setpoint is at the reinforcing plate, and the punching press of reinforcing plate in manufacturing process, welding between the subassembly, bordure with the planking, and dimensional deviation is accumulative, and the relative clearance of installing point and door planking floats on the final reinforcing plate, and can't compensate this deviation with ordinary fastening screw, and this just leads to the outward appearance face of handle to have the deviation, influences the curve molding of automobile body. The application provides an adjust poor mechanism of clearance face, the actual deviation volume of reinforcing plate that the initial design clearance of regulating part and locating part was allowed promptly, when the regulating part impels towards the direction that is close to the reinforcing plate, relative screw motion between base on the part and the regulating part, guarantee that the position of part does not change when the regulating part screw propulsion, when locating part and reinforcing plate butt, the precession action of regulating part stops, adjust the operation completion, tighten the mounting this moment and realize final part fastening, it can to avoid the locating part on the regulating part to take place the offset. This application absorbs manufacturing error through the cooperation of regulating part and locating part, guarantees the good matching of handle outward appearance face AND gate planking, realizes the smooth curve molding of automobile body, and the mounting prevents that regulating part and locating part from taking place the skew to promote the absorptive reliability of deviation.

The adjusting part is in threaded fit with the base, the part limits the base through a step surface on the mounting gap and the dead weight of the part, and when the adjusting part performs precession movement, the base synchronously rotates in the mounting gap without axial displacement, so that the change of the distance between the part at the position and the reinforcing plate is avoided.
