[0003] However, the existing universal inspection fixtures for exterior trim assemblies have the following defects during use: 1. When measuring the hole depth, a hole depth gauge is usually provided at the tail of the caliper. During measurement, since the hole depth gauge is fixedly connected to the caliper, the staff generally controls the hole depth gauge by holding the caliper body to measure, and during the operation, it is necessary to ensure that the front end surface of the hole depth gauge is flush with the surface of the rear port of the preset hole. Then the staff reads the front end surface of the preset hole through the surface scale of the hole depth gauge. During the reading process, it is also necessary to ensure the stability of the hole depth gauge to avoid the problem of inaccurate reading caused by offset. This method has high requirements for operation, and the measurement accuracy is easily affected by human factors. 2. When measuring the aperture, it is necessary to keep the measuring claw perpendicular to the preset hole port.

After that, the cross beam 33 can be reset, and the measuring mechanism 1 4 and the measuring mechanism 2 5 can perform corresponding detection work.

[0032] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The measuring mechanism 2 5 includes a sleeve 51 connected to the measuring mechanism 1 4. Four grooves 52 are evenly distributed along the circumference of the sleeve 51. A measuring slider 53 extending to the inside of the sleeve 51 is slidably arranged on a side wall of the groove 52 close to the center of the sleeve 51. The side of the measuring slider 53 away from the center of the sleeve 51 is arranged in a triangular cone shape. The lower side of the sleeve 51 is opened and a cover plate 6 is fixed by bolts.

One end of the spring 57 away from the connecting block 56 is fixedly connected to the inner wall of the movable hole 55. A measuring component 2 58 is jointly arranged between the upper side of the connecting block 56 and the upper side of the sleeve 51. A driving component 59 is arranged on the sleeve 51, and a limiting component 510 is also arranged on the sleeve 51.

[0033] See also Figure 5 , Figure 6 and Figure 7 A movable groove is provided on the inner wall of the groove 52 and above the corresponding measuring slider 53. The measuring component 1 54 includes a scale plate 1 541 fixedly arranged on the inner wall of the groove 52, and a pointer plate 1 542 corresponding to the adjacent scale plate 1 541 is slidably arranged in the movable groove; the measuring component 2 58 includes a scale plate 2 581 fixedly arranged on the upper side of the sleeve 51 and close to the upper end of each movable hole 55, and a pointer plate 2 582 corresponding to the adjacent scale plate 2 581 is fixedly arranged on the upper side of the connecting block 56.

[0034] See also Figure 5 and Figure 6The driving assembly 59 includes a rotating ring 591 rotatably arranged in the middle position of the upper side of the sleeve 51, and four transmission plates 592 distributed along the circumferential direction are hinged on the upper side of the rotating ring 591. The side of the transmission plate 592 away from the rotating ring 591 is rotatably connected to the upper side of the corresponding pointer plate 2 582.

[0035] See also Figure 6 The limit assembly 510 includes a screw rod 5101 rotatably arranged inside the sleeve 51, a limit platform 5102 with a conical structure is threadedly connected to the screw rod 5101, and the four measuring slide blocks 53 are in operative contact with the peripheral side wall of the limit platform 5102 at the side close to each other and close to the lower side. An adjusting knob 7 is rotatably arranged on the upper side of the sleeve 51, and the adjusting knob 7 is fixedly connected to the upper end of the screw rod 5101 through a connecting shaft. A guide rod 3 is fixedly arranged on the lower side of the limit platform 5102, and the lower end of the guide rod 3 is slidably plugged with the cover plate 6.

[0036] During specific operation, the second measuring mechanism 5 can be used alone to quickly detect whether there are problems with the same type of preset holes on the automobile exterior trim 8. When measuring the aperture of the same type of preset hole, after fixing the automobile exterior trim 8 on the base 1, the staff rotates the rotating ring 591 on the upper side of the sleeve 51 to cooperate with the transmission plate 592 so that the four measuring slide blocks 53 can be retracted into the sleeve 51. At this time, the sleeve 51 can be smoothly inserted into the preset hole. Then the staff loosens the rotating ring 591, and the four measuring slide blocks 53 move toward the inner wall of the preset hole under the action of the corresponding springs 57 and come into conflict. Then the staff rotates the adjusting knob 7 to make the screw 5101 rotate, thereby driving the limit platform 5102 to rise, so that the outer wall of the limit platform 5102 comes into conflict with the measuring slide block 53, and the measuring slide block 53 is limited. At this time, the measuring slide block 53 is limited by the inner wall of the preset hole and the limit platform 5102, and no longer moves. Then the staff reads the readings through any two opposite pointer plates 582 on the upper side of the sleeve 51 and their corresponding scale plates 581, such as Figure 7As shown. After reading the reading of the preset hole, determine whether the preset hole meets the requirements according to the parameters of the preset hole on the exterior design drawing. On the premise that the preset hole is qualified, the staff will pull the sleeve 51 out of the preset hole, and then move it to the top of the next preset hole. Before inserting the sleeve 51 into the preset hole below again, the staff will turn the rotating ring 591 again to control the measuring slider 53 to conflict with the limit table 5102. At this time, the distance between any two corresponding measuring sliders 53 ends on the sleeve 51 is the aperture of the previous preset hole. Keep this state and insert the sleeve 51 into the next preset hole. If it can be inserted just right, it means that there is no problem with the preset hole; if the sleeve 51 cannot be inserted into the preset hole or there is a certain distance between the end of the measuring slider 53 and the preset hole after the sleeve 51 is inserted, it means that there is a problem with the preset hole and it is unqualified. The same method can be used to quickly and quickly check the preset holes of the same model in batches.

[0037] When it is necessary to detect the hole depth of a preset hole on the automobile exterior trim 8, the measuring slider 53 on the sleeve 51 is completely retracted by rotating the rotating ring 591, and then the sleeve 51 is inserted into the preset hole so that the measuring slider 53 completely passes through the preset hole. Then the rotating ring 591 is loosened, so that the measuring slider 53 slides outward under the action of the corresponding spring 57 to be in a naturally stretched state, and then the sleeve 51 is pulled in the opposite direction. At this time, the measuring slider 53 conflicts with the back end of the preset hole, and then the pointer plate 1 542 moves downward to conflict with the front end of the preset hole. At this time, the thickness of the preset hole can be read by the position of the pointer plate 1 542 on the scale plate 1 541, as shown in FIG. Figure 8 As shown, the thickness of the preset hole can be accurately measured without precise control of the entire process.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The measuring mechanism 14 includes two card plates 41 with positioning pins on the lower side. The upper side of the crossbeam plate 33 is provided with a plurality of positioning holes distributed along the length direction thereof. The card plates 41 are plugged into the positioning holes through the positioning pins. A telescopic plate 42 is rotatably provided on the upper side of the card plate 41. A locking sleeve 43 is fixedly provided on the upper side of the movable section of the telescopic plate 42 and away from the card plate 41. A positioning rod 46 penetrating the movable section of the telescopic plate 42 is slidably plugged into the locking sleeve 43. A locking bolt is connected to the surface bolt of the locking sleeve 43. One end of the locking bolt abuts against the outer wall of the positioning rod 46. The lower end of the positioning rod 46 is fixedly connected to the upper side of the sleeve 51 through a connecting piece 44. A measuring plate 45 is slidably provided between the two positioning rods 46. The measuring plate 45 includes a ruler body with scales on the surface. A strip hole is provided on the upper side of the ruler body along the scale direction. The width of the strip hole is the same as the diameter of the positioning rod 46.

[0039] See also Figure 2 and Figure 4 The connecting member 44 includes a connecting plate 441 fixedly connected to the lower end of the positioning rod 46, and two electromagnetic rods 442 symmetrically arranged with the center of the positioning rod 46 as the midpoint are fixedly arranged on the lower side of the connecting plate 441. Two slots that are compatible with the electromagnetic rods 442 are opened at corresponding positions on the upper side of the sleeve 51, and iron sheets are fixedly arranged in the slots.

[0040] During specific operation, the measuring mechanism 2 5 can be used in conjunction with the measuring mechanism 1 4 to measure any two preset holes on the automobile exterior trim 8. When it is necessary to measure the distance between any two preset holes on the automobile exterior trim 8, first insert the sleeve 51 into the preset hole on the automobile exterior trim 8, and the four measuring sliders 53 on the outside of the same sleeve 51 all come into conflict with the preset holes. Then, the adjusting knob 7 at the upper end of the screw 5101 is rotated to make the limit platform 5102 rise and come into conflict with the four measuring sliders 53, so that the four measuring sliders 53 will not move even under pressure, so that the sleeve 51 is concentric with the preset hole. After the sleeve 51 is inserted into the preset hole, the corresponding positioning rod 46 is moved and the electromagnetic rod 442 is inserted into the slot on the upper side of the sleeve 51 to contact the iron sheet. At the same time, the electromagnetic rod 442 is energized to generate an adsorption force, so that the electromagnetic rod 442 is fixedly connected to the sleeve 51, thereby fixing the sleeve 51 at the preset position through the positioning rod 46. In the same way, another sleeve 51 is inserted into the corresponding preset hole. At this time, the two positioning rods 46 are inserted into the bar holes on the measuring plate 45. By comparing the positions of the two positioning rods 46 in the bar holes with the scales on the measuring plate 45, the distance between any two preset holes on the automotive exterior parts 8 can be accurately measured.
