[0030] Combined with Figures 1 to 5 As shown, the present utility model discloses an auxiliary measuring jig for automotive skin covering parts. The automotive skin covering part 8 has a first measuring surface 81 and a second measuring surface 82, and there is an included angle between the first measuring surface 81 and the second measuring surface 82. The auxiliary measuring jig for the automotive skin covering part includes:
[0031] A working platform 1;
[0032] A base 2; the base 2 is arranged on the working platform 1, and the base 2 has a profiling cavity for placing the automotive skin covering part 8, and the wall shape of the profiling cavity matches the outer peripheral shape of the automotive skin covering part 8; a first reference surface 21 and a second reference surface 22 are arranged on the base 2;
[0033] A first profiling component 23 and a second profiling component 24, the first profiling component 23 and the second profiling component 24 are arranged on the base 2;
[0034] When the automotive skin covering part 8 is placed on the base 2, the first profiling component 23 abuts against the back of the first measuring surface 81, and the second profiling component 24 abuts against the back of the second measuring surface 82; the first reference surface 21 is parallel to the first measuring surface 81, and the second reference surface 22 is parallel to the second measuring surface 82.
[0035] Compared with the prior art, the utility model can detect whether the thickness dimensions of the automotive skin covering parts 8 before and after skin covering meet the standards by measuring the distances between the first reference plane 21 and the first measuring plane 81 before and after skin covering on the surface of the parts, and the distances between the second reference plane 22 and the second measuring plane 82 before and after skin covering, and measuring the clearance values between the outer peripheral shape of the automotive skin covering parts 8 before and after skin covering and the wall surface of the profiling cavity. Only one set of inspection tools is needed to detect whether the thickness dimensions of the automotive skin covering parts 8 before and after skin covering meet the standards, effectively saving the detection cost and space.
[0036] Specifically, a surface difference gauge can be used to measure the distances between the first reference plane 21 and the first measuring plane 81 before and after skin covering of the automotive skin covering parts 8, and the distances between the second reference plane 22 and the second measuring plane 82 before and after skin covering, and a clearance measuring tool can be used to measure the clearance values between the outer peripheral shape of the automotive skin covering parts 8 before and after skin covering and the wall surface of the profiling cavity.
[0037] In one embodiment, the auxiliary measuring fixture for the automotive skin covering parts further includes a plurality of clamping structures 3, a steel wire rope 4 and a wire tightener 5; the clamping structure 3 includes a mounting block 31 arranged on the base 2 and a first clamping head 32 and a second clamping head 33 arranged on the mounting block 31. A groove is arranged between the first clamping head 32 and the second clamping head 33 for clamping the protruding part on the back of the automotive skin covering parts 8. The first clamping head 32 is fixed on the mounting block 31, and the second clamping head 33 can be opened outward relative to the first clamping head 32 and is connected to the wire tightener 5 through the steel wire rope 4. By controlling the wire tightener 5 to move the second clamping head 33 towards the first clamping head 32, the protruding part on the back of the automotive skin covering parts 8 is clamped by the first clamping head 32 and the second clamping head 33, achieving the effect of fixing the automotive skin covering parts 8. In this way, the staff does not need to hold the automotive skin covering parts 8 by hand during measurement.
[0038] Furthermore, a return spring is arranged between the second clamping head 33 and the mounting block 31. During the process of the wire tightener 5 tightening the second clamping head 33, since the two ends of the return spring are respectively abutted against the second clamping head 33 and the mounting block 31, the return spring is continuously compressed; after the wire tightener 5 loosens the second clamping head 33, the second clamping head 33 resets under the action of the return spring to loosen the automotive skin covering parts 8.
[0039] In one embodiment, after the automotive skin covering part is placed on the base, the first reference plane is higher than the first measurement plane; the second reference plane is located outside the second measurement plane; and the upper surface of the automotive skin covering part 8 is an arc surface or a flat surface, lacking a part that can serve as a handle. Therefore, to facilitate the staff to take out the automotive skin covering part 8 from the profiling cavity, the auxiliary measurement fixture for the automotive skin covering part further includes a first reference plate 6 and a flipping structure 7. The upper surface of the first reference plate 6 constitutes the first reference plane 21, and the first reference plate 6 is placed on the base 2; the flipping structure 7 is arranged on the working platform 1, and the flipping structure 7 is fixedly connected to the first reference plate 6 to drive the first reference plate 6 to rotate. The present utility model provides a rotatable first reference plate 6. After the reference plate is flipped upward, the bending edge of the automotive skin covering part 8 can be exposed. The staff can apply force to the bottom of the bending edge with their hands to take out the automotive skin covering part 8. After taking out the automotive skin covering part 8, the first reference plate 6 can be flipped back onto the base 2 again, so that the first reference plate 6 is placed back on the base 2 again, ensuring that the position of the first reference plane 21 remains fixed during measurement and does not affect the measurement accuracy.
[0040] Further, to flip the first reference plate 6, the flipping structure 7 includes a lifting seat 71, two limiting support blocks 72, a pin shaft, and a flipping bar 73; the lifting seat 71 is fixed on the working platform 1; the two limiting support blocks 72 are arranged on the lifting seat 71; the flipping bar 73 is arranged between the two limiting support blocks 72; the pin shaft passes through the two limiting support blocks 72 and the flipping bar 73.
[0041] Further, to define the limit position of the upward flipping of the first reference plate 6, the flipping structure 7 further includes a limiting member 74; the limiting member 74 is arranged at the rear side of the flipping bar 73, and a limiting inclined surface 741 is arranged on the side of the limiting member 74 facing the flipping bar 73; during the upward rotation of the flipping bar 73, the surface of the flipping bar 73 abuts against the limiting inclined surface 741. At this time, the flipping bar 73 cannot continue to rotate under the limitation of the limiting inclined surface 741, so as to define the limit position after the first reference plate 6 is flipped upward.
[0042] The above description is an explanation of the present utility model, not a limitation of the utility model. The scope defined by the present utility model can be seen in the claims. Within the protection scope of the present utility model, any form of modification can be made.
[0043] The present utility model is not limited to the above embodiments. If various modifications or variations of the present utility model do not depart from the spirit and scope of the present utility model, and provided that these modifications and variations fall within the scope of the claims of the present utility model and equivalent technical scope, then the present utility model also intends to encompass these modifications and variations.
