Detailed Description

The technical solutions in the embodiments of the present utility model are clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The specific embodiments described herein are to be considered in an illustrative sense only and are not intended to limit the utility model.

The novel gauge of the multifunctional bracket for the front bumper of the automobile, as shown in fig. 1, comprises a base 1, a measuring reference 2, a profiling positioning table 3, a pressing clamp 4, a positioning block 5, a plane alignment gauge 6 and a feeler gauge 7. The three measurement references 2 are respectively arranged at three corners of the rectangular base 1, and provide reference coordinate origins for installation debugging, processing and future repeatability detection of the gauge. Lifting handles 11 are arranged on two sides of the base 1.

The profiling positioning table 3 is fixedly connected to the middle position of the top of the base 1, the three pressing pincers 4 surround the profiling positioning table 3 in a triangular shape, a datum point 31 longitudinally corresponding to a pressing head of the pressing pincers 4 is arranged on the table surface of the profiling positioning table 3, and the datum point 31 is used as a datum to support a bracket to be tested. The clamp 4 with the pressure of 10N is selected, so that the bracket to be measured is tightly contacted with the reference, the bracket is deformed due to the too large pressure, and the bracket is shifted during measurement due to the too small pressure.

The number of the positioning blocks 5 is 3, the two positioning blocks A51 are tangent to the bottom edge of the profiling positioning table 3, the other positioning block B52 is tangent to the right side edge of the profiling positioning table 3, and the positioning blocks 5 serve as references for the support 8 to be tested to be positioned in an abutting mode. The two positioning blocks A51 are respectively positioned at two ends of the bottom edge of the profiling positioning table 3.

The feeler gauge 7 is placed on the magnetic suction seat on the base 1, and the design thickness of the feeler gauge 7 is 1.3mm. The feeler gauge is used for detecting the gap between the adhesive surface 81 at the bottom of the bracket 8 to be detected and the reference surface at the top of the profiling positioning table. The bottom of the adhesive surface 81 is provided with a boss with the thickness of 0.8mm, the flatness of the adhesive surface is required to have the tolerance of +/-0.5 mm, so that a feeler gauge 7 with the design thickness of 0.8+0.5=1.3 mm is selected, as shown in figures 2, 3 and 4,

the flat gauge 6 is clamped and fixed by a fixing clamp on the base 1, the tolerance required by the contour degree of the circumference of the bracket 8 to be tested is +/-0.5 mm, and the standard surface difference of the flat gauge 6 is +/-0.5 mm.

When the novel gauge for the automobile front-guard multifunctional support is adopted, the support 8 to be tested is firstly placed on the profiling positioning table 3, the support 8 to be tested is enabled to be aligned with the positioning block, and then the pressing clamp 4 is closed to fix the support 8 to be tested.

When the flatness of the adhesive surface of the bracket 8 to be detected is detected, as shown in fig. 4, the feeler gauge 7 is plugged into a gap between the adhesive surface at the bottom of the bracket to be detected and the reference surface at the top of the profiling positioning table, if the gap cannot be plugged into the gap, the adhesive surface is qualified in flatness, and otherwise, the flatness is unqualified.

When the contour degree of the peripheral surface of the bracket 8 to be detected is detected, as shown in figure 5, the protruding section of the plane alignment gauge 6 is attached to the profiling positioning table 3, and the plus 0.5 requirement is met if the upper part does not contact the contour of the bracket 8 to be detected; the protruding section of the plane alignment gauge 6 is tightly attached to the outline of the bracket 8 to be tested, and the lower part is not connected with the profiling positioning table 3, so that the requirement of-0.5 is met. If the whole contour meets the measurement requirement, the contour degree of the circumferential surface of the bracket 8 to be measured is qualified, and otherwise, the contour degree of the circumferential surface of the bracket to be measured is opposite.
