Description

Technical Field

[0001] The utility model relates to an assembly inspection tool for a rear side panel of a car tailgate. Background Art

[0002] The tailgate, also known as the trunk lid, is mainly used to protect and store items while providing convenience and safety. The rear side panel assembly is a component that surrounds the rear of the car body and cooperates with the tailgate. Its function is to enhance the strength of the trunk and enable the opening and closing of the tailgate. The rear side panel assembly of the tailgate is semi-enclosed and is welded or riveted from multiple parts. Since the rear side panel assembly of the tailgate also needs to have functions such as anti-collision, sealing and wiring, its structure is relatively complex.

[0003] In order to ensure the accuracy of the shape, size, hole position and other aspects of the rear side panel assembly of the automobile tailgate, it is necessary to use the matching inspection fixture to inspect the assembled rear side panel assembly of the automobile tailgate.

[0004] However, the existing inspection fixtures for the rear side panel assembly of the automobile tailgate cannot simultaneously inspect various items of the rear side panel assembly of the automobile tailgate. Instead, at least two sets of inspection fixtures must be made and the inspection must be carried out in two steps, namely, the rear side panel assembly of the automobile tailgate is first placed and fixed on one of the inspection fixtures to verify its shape and size accuracy, and then the rear side panel assembly of the automobile tailgate is removed and fixed on the other inspection fixture to inspect the position accuracy of each hole position and each locating pin on the rear side panel assembly of the automobile tailgate. Therefore, the inspection steps are relatively cumbersome, and the rear side panel assembly of the automobile tailgate must be fixed and removed at least twice, which is time-consuming and labor-intensive, resulting in low inspection efficiency. In addition, the need to make two sets of inspection fixtures will lead to increased inspection costs, which needs to be further improved. Utility Model Content

[0048] Working principle:

[0049] Push the crank of the pull rope mechanism 113 in each clamping assembly to drive the two clamping blocks of each two-way buckle mechanism 112 to separate from each other through the corresponding brake line; the two-way buckle mechanism and the pull rope mechanism are both standard parts used in the field of automotive inspection fixtures, and their structure and the principle of connecting the pull rope mechanism to the two-way buckle mechanism through the brake line to play a driving role are both existing technologies.

[0050] Next, pull up the swing ends of the first horizontal turning mechanism 3, the second horizontal turning mechanism 92 in each first basic detection unit 9, and the third horizontal turning mechanism 102 in each second basic detection unit 10 to respectively drive the press frame 4, the first press beam 93, and the second press beam 103 to rotate upward; the horizontal turning mechanism is a standard part used in the field of automotive inspection fixtures, and its structure and use method are both existing technologies.

[0051] Next, the rear side panel assembly of the automobile tailgate is horizontally pressed onto the top of the first support beam 5, the second support beam 6 and the third support beam 7 in the two support assemblies, and the middle part of the rear side panel assembly of the automobile tailgate is located below the pressing frame 4. At the same time, the left and right sides of the rear side panel assembly of the automobile tailgate are respectively pressed onto the positioning beams 83 in the two precise positioning assemblies 8.

[0052] Subsequently, the swing ends of the first horizontal flipping mechanism 3, the second horizontal flipping mechanism 92 in each first basic detection unit 9, and the third horizontal flipping mechanism 102 in each second basic detection unit 10 are swung downward to drive the pressure frame 4, the first pressure beam 93 and the second pressure beam 103 to rotate downward in the same way, until the pressure frame 4, the first pressure beam 93 and the second pressure beam 103 are all pressed against the top of the rear side panel assembly of the automobile tailgate, and then the first horizontal flipping mechanism 3 and the second horizontal flipping mechanism 92 in each first basic detection unit 9 are locked, thereby completing the fixation of the rear side panel assembly of the automobile tailgate.

[0053] At this time, each positioning pin located on the rear side panel assembly of the automobile tailgate extends between the two clamping blocks in a corresponding two-way snap mechanism 112; thereafter, the pull rope mechanism 113 and the crank handle are pulled to drive the two clamping blocks of each two-way snap mechanism 112 to move closer to each other through the corresponding brake line; and then the two clamping blocks of each two-way snap mechanism 112 clamp the corresponding positioning pin, thereby completing the precise positioning of the rear side panel assembly of the automobile tailgate.

[0054] Finally, the first detection pin 843 in the first detection module in each lateral detection unit 84 and the second detection pin 842 in each second detection module are screwed in turn, so that the detection ends of each first detection pin 843 and each second detection pin 842 are close to the rear side panel assembly of the automobile tailgate, until the detection end of each first detection pin 843 and each pressure block 849 are pressed tightly against the outer wall of the rear side panel assembly of the automobile tailgate, so as to determine whether the hole position, hole spacing and hole diameter values ​​of each mounting hole located on the left and right sides of the rear side panel assembly of the automobile tailgate are qualified.

[0055] After the first pressure beam 93 and the two second pressure beams 103 are pressed against the top of the rear side panel assembly of the automobile tailgate, the first curved surface 933 on each first protrusion 931, the second curved surface 1033 on each second protrusion 1031, the third curved surface 1072 on each third pressure plate 1071, and the fourth curved surface 1052 on each fourth pressure plate 1051 will all be pressed against the outer wall of the rear side panel assembly of the automobile tailgate, so that each part of the rear side panel assembly of the automobile tailgate can be pressed and fixed without displacement; then each fourth detection pin 94, each fifth detection pin 104, each sixth detection pin 108, and each seventh detection pin 106 are screwed in turn so that their detection ends are all pressed against the outer wall of the rear side panel assembly of the automobile tailgate, so as to judge whether the hole position, hole spacing, and hole diameter values ​​of each mounting hole in front of the rear side panel assembly of the automobile tailgate are qualified.

[0056] The utility model only needs one inspection fixture to simultaneously inspect various items of the rear side panel assembly of the automobile tailgate, and only needs to perform the fixing and removing operations once, thereby simplifying the inspection steps to achieve the effect of saving time and labor and improving the inspection efficiency. In addition, it also reduces the inspection cost.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
