Problems solved by technology

Most of the traditional pre-treatment electrophoresis four-door tooling accessories are connected by bolts. There are three main problems in this method: first, the four-door tooling is not universal, and it is divided into left tooling and right tooling. Because of the small difference, it is not convenient for on-site tooling Second, the bolt holes on the car body shake, the manual screw connection takes a long time, and the ergonomics are poor; third, the tooling is complicated, the processing is difficult, and the investment is high

Embodiment 1

[0024] like Figure 1 to Figure 2 As shown, a four-door general-purpose tooling for pre-painting electrophoresis, including a connecting rod 1, positioning structures respectively arranged at both ends of the connecting rod 1 and a hooking and tensioning mechanism that can be deformed to form a tensioning force, one end of the connecting rod 1 The hooking and tensioning mechanism is hooked and connected with the vehicle body, and the other end is positioned and connected with the car door through a positioning structure.

[0025] Wherein, the positioning structure is the positioning pin 2 . Locating pin 2 is concentrically located with the locating hole of the car door, and the locating pin is the benchmark of the whole frock. The positioning pin 2 is preferably a lower circle upper cone structure, the lower circle upper cone structure includes a circular column for connecting the positioning hole of the car door and a tapered structure arranged on the circular column for fit...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that the connecting rod is a telescopic rod, and the purpose is to adjust the distance between the hook and the positioning pin according to the structure of different vehicle models. The telescopic rod can adopt two sleeve rods that are nested with each other. The inner sleeve rod is provided with multiple positioning holes in the axial direction, and the outer sleeve rod is provided with elastic positioning protrusions, which cooperate with different positioning holes through the elastic positioning protrusions. Realize the telescopic adjustment of two sets of rods. Of course, the connecting rod can also be an electric push rod, the positioning pin is arranged at the telescopic end of the electric push rod, and the hook and the spring are arranged at the tail end of the electric push rod.

Abstract

The invention discloses a four-door universal tool for processing electrophoresis before coating. The tool comprises a connecting rod, positioning structures and a hooking and tensioning mechanism, wherein the positioning structures are arranged at the two ends of the connecting rod, and the hooking and tensioning mechanism can be deformed to form a tensioning force; and one end of the connectingrod is connected to a vehicle body in a hooked mode through the hooking and tensioning mechanism, and the other end is connected to a vehicle door in a positioning mode through a positioning structure. According to the tool, the vehicle door can be firmly connected to the vehicle body, so that the opening angle of the vehicle door and the vehicle body is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electrophoretic painting auxiliary tools for pretreatment of automobiles, and in particular relates to a four-door general tooling for electrophoresis of prepainting treatment. Background technique [0002] During the pre-treatment and electrophoresis process of the car's body-in-white, in order to ensure the smooth discharge of the pre-treatment and electrophoresis tank solution, it is necessary to form a certain angle gap between the door and the body, so as to realize the smooth flow of the tank solution within the specified process time. In order to achieve this goal, it is necessary to use pre-treatment electrophoresis tooling accessories. Most of the traditional pre-treatment electrophoresis four-door tooling accessories are connected by bolts. There are three main problems in this method: first, the four-door tooling is not universal, and it is divided into left tooling and right tooling. Because o...
