Description

Technical Field

[0001] The utility model relates to the field of automobile body assembly welding, in particular to a simple tool for welding a rear panel assembly. Background Art

[0002] The welding of the rear panel assembly requires welding the rear panel attachment parts, such as the rear panel reinforcement plate, the rear seat hook bracket, and the rear ceiling mounting bracket, to the rear panel body to form the rear panel assembly.

[0003] At present, the rear panel parts are measured by tape measure and marked manually, and the handheld parts are welded by CO2 shielded welding. This method has obvious defects:

[0004] Measuring with a tape measure and marking by hand, and locating parts by marking, there will be deviations in the operation itself. After the hands are released after positioning and welding, there will also be deviations in welding deformation.

[0005] When welding handheld workpiece parts, only two-way welding can be used for positioning, and resistance welding cannot be used. Two-way welding requires CO2 gas and welding filler materials, so the welding cost is relatively high.

[0006] On-site operators hold the workpiece in one hand and the welding gun in the other, which can easily burn their hands during welding and also pose a safety hazard.

[0007] Each time the rear panel assembly is welded, each component that needs to be welded to the rear panel needs to be measured and marked with a tape measure, which is difficult and time-consuming to manufacture and has low work efficiency. Utility Model Content

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0060] The structure of the simple tooling for welding the rear panel assembly is as follows Figure 1-3 shown.

[0061] The support frame includes a bottom plate 1, a support column 2, and a base plate 3 fixed in sequence from bottom to top. A plurality of support rods 4 are fixed on the top of the base plate to support the rear panel body 14 and to install the rear panel body positioning and clamping unit and the rear panel additional parts positioning and fixing unit. The base plate 3 is also fixed with a welded lifting ring 10 for lifting the entire device.

[0062] The rear panel body positioning and pressing unit comprises a rear panel body positioning sub-unit and a rear panel body pressing sub-unit.

[0063] The rear panel body positioning subunit includes two or more main body positioning pins 9, which are fixed to the top of the support rod 4 through a cross bar. The main body positioning pins 9 cooperate with the positioning holes of the rear panel body to position the rear panel body. In this embodiment, two main body positioning pins 9 are used.

[0064] The rear panel body clamping subunit adopts a rear panel body clamp installed on the top of the support rod 4. The upper part of the rear panel body clamp is a movable part, which has a handle and is connected to the lower part through a connecting plate 11. The lower part is a fixed part, which has a support point 8 for supporting the rear panel body. The rear panel body clamp can be installed on the top of the same support rod 4 as the main body locating pin 9, or it can be installed separately on the top of a support rod 4. In this embodiment, the first rear panel body clamping subunit 12 is installed on the top of the same support rod 4 as the main body locating pin 9, and the second rear panel body clamping subunit 13 is installed separately on the top of a support rod 4.

[0065] The rear panel additional parts positioning and fixing unit includes: a rear panel reinforcement plate positioning and fixing and rear seat hook positioning and fixing integrated unit, which is used to position and fix the rear panel reinforcement plate and the rear seat hook; and a ceiling rear mounting bracket positioning and fixing unit, which is used to position and fix the ceiling rear mounting bracket.

[0066] The rear panel reinforcement plate positioning and fixing and rear seat hook positioning and fixing integrated unit comprises a rear panel reinforcement plate positioning and fixing unit and a rear seat hook positioning and fixing unit.

[0067] The rear panel reinforcement plate positioning and fixing unit is used to position and fix the rear panel reinforcement plate in the width direction. In this embodiment, the rear panel reinforcement plate positioning and fixing unit has two, which are in the form of a clamp structure in which the lower arm fixes the upper arm and the upper arm is movable, and are respectively a first rear panel reinforcement plate positioning and fixing unit 20 and a second rear panel reinforcement plate positioning and fixing unit 21, each of which is rotatably mounted on the top end of a support rod 4 through a rotating mechanism 7.

[0068] There are two rear seat hook positioning and fixing units, which also adopt the clamp structure form and are installed at the two ends of the rear panel reinforcement plate in the length direction, namely the first rear seat hook positioning and fixing unit 17 and the second rear seat hook positioning and fixing unit 18, each of which is installed on the top of a support rod 4.

[0076] Hang the rear ceiling mounting bracket to the positioning pin of the rear ceiling mounting bracket positioning and fixing unit, pull the handles of the rear ceiling mounting bracket positioning and fixing unit in turn, and the positioning pin extends to position and fix the rear ceiling mounting.

[0077] The rear panel body and rear panel attachment parts are positioned and fixed, and resistance welding is used for welding. After welding, loosen the clamps of the rear panel body positioning and clamping unit, the rear panel reinforcement plate positioning and fixing unit, and the rear seat hook positioning and fixing unit, and bend the handle backward to release the rear panel body. Return the positioning pin of the mounting bracket positioning and fixing unit.

[0078] After welding is completed, open all clamping positions and remove the rear panel assembly from the tooling. After passing the inspection, load it onto the turnover material rack and transport it to the next sequence.

[0079] It can be seen that the simple tooling of the rear panel assembly provided in this embodiment is convenient for mounting, and the parts to be welded can be conveniently positioned, thereby improving work efficiency. The parts are positioned by positioning pins and manual clamping, which improves the welding accuracy of the parts. At the same time, the tooling can also assist in detecting the status of the parts, thereby playing the role of a check fixture; the welding process of the parts with the tooling positioning parts can be replaced by resistance welding, and the deviation caused by offset during welding will not occur, thereby improving production efficiency and reducing production costs.
