Description

Technical Field

[0001] This utility model relates to the technical field of automotive B-pillar guard plate detection equipment, and in particular to an automotive B-pillar guard plate contour detection device. Background Technology

[0002] The B-pillar, located between the front and rear doors, is an indispensable part of a car. Its complex structure makes it a crucial component of the vehicle body, supporting the roof, connecting the rear and front door locks, and securing seatbelts. In the event of a collision, it mitigates the dangers of side impacts, ensuring occupant safety. The B-pillar trim is a structural component, typically made from cold-rolled steel. Currently, the production of high-strength steel in China usually involves processes such as drawing, trimming, punching, and shaping, requiring stringent selection of forming technology. Considering the need for welding and matching with other parts during assembly, this component requires high precision and also functions as a door self-locking safety device, providing anti-theft and sealing effects. To meet side impact safety standards, car manufacturers require component manufacturers to use high-strength steel plates in the manufacture of car B-pillars.

[0003] Chinese patent CN209399962U discloses a molding fixture for automotive B-pillar trim panels, including an upper mold base and a lower mold base, an upper mold detection block on the upper mold base, and a lower mold fixing block on the lower mold base. The mating surfaces of the upper mold detection block and the lower mold fixing block form a detection cavity.

[0043] Please see Figure 1 This invention discloses a vehicle B-pillar guard plate contour detection device 100, comprising a base plate 10, a detection platform 20, a positioning mechanism 30, a contour limiting frame 40, and a rapid detection head 50. The detection platform 20 is fixedly mounted on the base plate 10, and the positioning mechanism 30 is mounted on the detection platform 20. The positioning mechanism 30 is used to fix the vehicle B-pillar guard plate 200 on the detection platform 20. The contour limiting frame 40 is detachably mounted on the detection platform 20 via a threaded connection. The contour limiting frame 40 is arranged circumferentially around the vehicle B-pillar guard plate 200. A detection gap 60 is provided between the side end of the vehicle B-pillar guard plate 200 and the adjacent contour limiting frame 40. The rapid detection head 50 is used to quickly determine whether the vehicle B-pillar guard plate 200 is qualified by whether it can be inserted into the detection gap 60. The rapid detection head 50 includes a small rapid detection head and a large rapid detection head. The small rapid detection head has a diameter of 4.5 mm, and the large rapid detection head has a diameter of 5.5 mm.

[0044] The specific testing principle is as follows: When the standard B-pillar guard plate is placed in the middle of the contour limiting bracket 40, the testing gap 60 is 5mm. At this time, the small rapid testing head can extend into the testing gap 60 and circle around the B-pillar guard plate 200, while the large rapid testing head cannot extend into the testing gap 60. Therefore, when the small rapid testing head cannot extend into the testing gap 60, it proves that the contour of the B-pillar guard plate 200 is unqualified and the size of the B-pillar guard plate 200 is too large; when the large rapid testing head can extend into the testing gap 60, it proves that the contour of the B-pillar guard plate 200 is unqualified and the size of the B-pillar guard plate 200 is too small.

[0052] Please see Figure 1The automobile B-pillar guard plate contour detection device 100 further includes a difference measurement component 70, which includes a measurement positioning seat 71, a bracket 72, a fixing screw 73, and a measuring dial indicator 74. The measurement positioning seat 71 is disposed on the detection table 20, and the bracket 72 is hinged to the measurement positioning seat 71. The measurement positioning seat 71 is provided with a fixing screw hole. The measuring dial indicator 74 is fixed on the bracket 72. The contour limiting frame 40 is provided with a positioning groove 41 and a slot 42. The fixing bolt passes through the bracket 72 and engages with the fixing screw hole. The bracket 72 is inserted into the positioning groove 41. The elastic measuring head of the measuring dial indicator 74 passes through the slot 42 and abuts against the side end of the automobile B-pillar guard plate 200.

[0053] Please see Figure 1 The automotive B-pillar guard plate contour detection device 100 also includes a calibration component 80 for zeroing the dial gauge 74. The calibration component 80 is fixed on the base plate 10, which allows for constant calibration of the dial gauge 74, effectively improving the accuracy of the measurement data. In this embodiment, the calibration length of the calibration component 80 is 50mm.

[0054] The detection principle is as follows: Since a standard B-pillar guard plate is placed in the middle of the contour limiting bracket 40, when the elastic detection head of the measuring dial indicator 74 abuts against the standard B-pillar guard plate, the reading of the measuring dial indicator 74 is 0. Therefore, during measurement, if the reading of the measuring dial indicator 74 is positive, it proves that the edge of the B-pillar guard plate 200 is concave inwards; if the reading of the measuring dial indicator 74 is negative, it proves that the edge of the B-pillar guard plate 200 is convex outwards. For example, if the reading of the measuring dial indicator 74 is 1mm during measurement, it proves that the edge of the B-pillar guard plate 200 is 1mm more concave inwards than the standard B-pillar guard plate; similarly, if the reading of the measuring dial indicator 74 is -1mm during measurement, it proves that the edge of the B-pillar guard plate 200 is 1mm more convex outwards than the standard B-pillar guard plate.

[0055] The working principle of the B-pillar guard plate contour detection device 100 in this embodiment is as follows: During operation, the B-pillar guard plate 200 is placed on the fixed pad 351, and the edge of the B-pillar guard plate 200 is engaged between the longitudinal fixed clamping block 331 and the longitudinal movable clamping block 332, as well as between the transverse fixed clamping block 321 and the transverse movable clamping block 322. The longitudinal positioning rod 333 is pulled, causing the longitudinal fixed clamping block 331 and the longitudinal movable clamping block 332 to press against each other, thereby achieving longitudinal positioning of the B-pillar guard plate 200. Simultaneously, pull the lateral positioning lever 323 to make the lateral fixed clamping block 321 and the lateral movable clamping block 322 press against each other to achieve lateral positioning of the car B-pillar guard plate 200. Then, manually drive the handle 345 to lock the locking assembly 34. Then, twist the rotary rod 353 to make the snap-fit ​​block 3531 rotate out from the upper limit groove 3541 and snap into the pressing groove 3542. Under the action of the pressing spring 355, the pressing block 352 is driven to press the car B-pillar guard plate 200 onto the fixed pad 351. This achieves the positioning of the car B-pillar guard plate 200.

[0056] During contour inspection, the contour limiting frame 40 is fixed to the inspection table 20 by screws. The contour limiting frame 40 is arranged circumferentially around the B-pillar guard plate 200 of the car. A large and a small rapid inspection head are used to perform a quick contour inspection of the B-pillar guard plate 200 to quickly determine whether it is qualified. If qualified, the next B-pillar guard plate 200 is inspected. If not, a dial indicator 74 is used to measure the difference in the B-pillar guard plate 200. This allows users to easily correct the B-pillar guard plates 200, turning some unqualified B-pillar guard plates 200 into qualified products, reducing material waste, being more environmentally friendly, and effectively reducing production costs.

[0057] The beneficial effects of this utility model are as follows: through the cooperation of the base plate 10, the testing table 20, the positioning mechanism 30, the contour limiting frame 40 and the rapid testing head 50, the vehicle B-pillar guard plate 200 can be quickly tested to determine whether it is qualified. The testing accuracy is high and the testing efficiency is effectively improved.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
