Description

Technical Field

[0001] The utility model relates to a checking fixture for an upper decorative plate of an A-pillar of an automobile. Background Art

[0002] The A-pillar of a car is a connecting column that is located on the left and right front of the car, connecting the roof and the front cabin. The upper trim of the A-pillar is a plate-like part installed on the upper part of the A-pillar for decorative purposes. Since the upper trim of the A-pillar needs to cover multiple positions, its contour is irregular, and the surface is not flat, but has ups and downs. After the A-pillar upper trim is produced, it must be inspected with a matching inspection fixture to verify the position accuracy of each mounting hole. The inspection fixture is a fixture used to fix the workpiece for easy inspection.

[0003] Since the mounting holes on the A-pillar upper trim are not distributed in a centralized manner, but are divided into three areas, each area is provided with a plurality of mounting holes; however, the existing inspection fixture for the A-pillar upper trim cannot detect the mounting holes in each area at the same time, but needs to be carried out in three steps, and three independent matching inspection fixtures need to be made to inspect the mounting holes in each area in turn, so the operation is quite troublesome, and it takes a lot of time to transfer the A-pillar upper trim back and forth between the three inspection fixtures, which is both time-consuming and labor-intensive, resulting in low work efficiency, and also increases the manufacturing cost of the inspection fixture, so further improvement is needed.

[0033] Then place the A-pillar upper trim flat on the first support dam 22, the second support dam 25, the third support dam 21, the fourth support dam 23, the fifth support dam 24, the sixth support dam 27 and the seventh support dam 26. The tops of the first support dam 22, the second support dam 25, the third support dam 21, the fourth support dam 23, the fifth support dam 24, the sixth support dam 27 and the seventh support dam 26 will be correspondingly attached to the structural surface on the lower outer wall of the A-pillar upper trim; then the swing ends of the first quick clamp 82 in each first clamping unit 8 and the second quick clamp 92 in each second clamping unit 9 are swung downward to the bottom, so that the first pressing head 83 in each first clamping unit 8 and the second pressing head 94 in each second clamping unit 9 are pressed on the upper outer wall of the A-pillar upper trim, thereby completing the preliminary positioning of the A-pillar upper trim.

[0034] Then, the ends of the swing rods of the first horizontal flipping mechanism 36, the second horizontal flipping mechanism 32, the third horizontal flipping mechanism 42, the fourth horizontal flipping mechanism 45, the fifth horizontal flipping mechanism 49, the sixth horizontal flipping mechanism 52, the seventh horizontal flipping mechanism 55, the eighth horizontal flipping mechanism 59, the ninth horizontal flipping mechanism 62 and the tenth horizontal flipping mechanism 72 are all swung downward to the bottom, so that the first limiting beam 37, the second limiting beam 33, the first positioning piece 43, the second positioning piece 46, the third positioning piece 47, the fourth positioning piece 410, the linear molding 53, the third limiting beam 56, the arc molding 510, the fifth positioning piece 63 and the sixth positioning piece 73 are all fitted to the corresponding positions of the upper outer wall of the A-pillar upper trim.

[0035] Finally, a first detection pin 39 is inserted into each pressure block 38, and multiple second detection pins 34 are inserted into the second limiting beam 33, so that the end of each first detection pin 39 and each second detection pin 34 close to the A-pillar upper trim is inserted into the corresponding structural hole on the A-pillar upper trim above the first support dam 22 to verify its size and position; then, multiple third detection pins 57 are inserted into the third limiting beam 56, and the end of each third detection pin 57 close to the A-pillar upper trim is inserted into the corresponding structural hole on the A-pillar upper trim above the third support dam 21 to verify its size and position.
