[0037] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. Furthermore, it should be understood that the use of the term "including", "comprising" or "having" herein is meant to be inclusive of the features, steps, operations, devices, components, and / or combinations thereof.

[0038] Noun explanation:

[0039] DTS refers to the design requirement of the gap and surface difference between each part of the vehicle appearance, which is an important indicator of the manufacturing quality of the vehicle appearance, and is a manifestation of the manufacturing level of the vehicle size quality, and is the subjective evaluation of the customer on the product quality. That is, DTS is the requirement for the matching relationship between parts, including the gap and surface difference of part matching.

[0040] In the whole vehicle assembly process of the automobile manufacturing industry, the vehicle body is adjusted to the standard state after each process, such as the front cover inner plate assembly lock buckle adjustment. The front cover inner plate is an outer covering part of the automobile body, which plays a role in decoration and ensuring the quality of the outer surface of the automobile body. The front cover inner plate is usually matched with the two side fenders, left and right headlamps, front bumpers and the like. The plastic front cover inner plate is assembled in the general assembly workshop, and the sheet metal front cover inner plate is assembled in the welding assembly, which needs to be repeatedly adjusted by each process to reach the standard state. In order to simulate the whole vehicle matching state, some auxiliary assembly devices are needed during assembly.

[0041] The automobile front cover inner plate is installed on the vehicle body through a hinge. The current automobile front cover inner plate is generally installed on the main vehicle body by manual installation. First, the automobile front cover inner plate is positioned and installed on the main vehicle body in an open state through an assembly tool. After the installation is completed, the automobile front cover inner plate is closed, and then manual adjustment is performed on the automobile front cover inner plate according to the DTS requirements. The manual repeated opening and closing of the front cover inner plate for adjustment consumes a long working time and is inconvenient to operate. In order to solve the above technical problems, effectively control the assembly posture of the front cover inner plate on the vehicle body, improve the assembly efficiency, and at the same time ensure the DTS qualified rate and assembly consistency, the present application provides an automobile front cover inner plate assembly tool for online adjustment auxiliary positioning of the automobile front cover inner plate, which can effectively ensure the consistency and reduce the time of repeated manual adjustment.

[0042] As shown in Figure 2 An embodiment of the present application provides an automobile front cover inner plate assembly tool 1 for fixing the front cover inner plate 3 and the hinge 2, which improves the assembly efficiency, reduces the cost and reduces the weight feeling of the employee operation.

Therefore, the assembling tool 1 of the present application can realize the closed clamping of the front cover inner plate 3, ensure the gap between the front cover inner plate 3 and the surrounding matched parts, and the height of the whole tool is about 70mm, avoiding the problems of large traditional tool and repeated adjustment of half-open clamping. The tool has small volume and is convenient to operate, effectively ensures the DTS requirement of the front cover inner plate 3, reduces the time waste caused by repeated adjustment of employees, and reduces the labor intensity of employees.

[0045] As shown in Figure 6 、 Figure 7 , the protruding block 122 has two sliding grooves 125, the two sliding grooves 125 are inclined grooves and are symmetrically arranged, the two sliding grooves 125 form an eight-shaped groove, the movable clamp plate 13 has two, and the two movable clamp plates 13 are respectively installed in the two sliding grooves 125, as shown in Figure 4 . When the lower end of the movable clamp plate 13 moves to both sides, the whole movable clamp plate 13 slides downward along the eight-shaped sliding groove 125, thereby tightening the front cover inner plate 3 and the hinge 2.

The assembler places the front cover inner plate 3 on the vehicle body, at this time the hinge 2 of the front cover inner plate 3 is in a freely movable state with the vehicle body, at this time the assembler measures whether the gap between the front cover inner plate 3 and the fender meets the DTS standard. If not, the assembler adjusts the hood to meet the requirements, presses the clamping button on the control box, the motor rotates forward, the ball nut rotates downward, drives the movable clamp plate 13 to move downward, until the front cover inner plate 3 is attached to the hinge 2. Through the downward pulling force of the movable clamp plate 13 and the upward force of the hinge 2, an upward and downward clamping force is formed, which ensures that the hinge 2 and the front cover inner plate 3 do not displace and play a fixing role. The assembler opens the front cover inner plate 3 to bolt connect the front cover inner plate 3 and the hinge 2. Press the release button on the control box, the motor reverses, the ball nut rotates upward, drives the movable clamp plate 13 to rise upward, forms a gap between the movable clamp plate 13 and the front cover inner plate 3, manually rotates the tool in the reverse direction, removes the tool, and completes the assembly adjustment of the front cover inner plate 3.
