Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile part manufacturing inspection, specifically to a detection tool for the contour and partial position of an automobile front anti-collision beam. BACKGROUND

[0002] The front impact beam is located behind the front bumper and can improve the impact stiffness of the automobile, limit deformation, support the body structure and protect other components. The traditional front impact beam workpiece is manufactured by stamping steel. In recent years, due to the development of automobile lightweight, more and more front impact beams of vehicles are manufactured by aluminum profiles. The processing technology of aluminum profiles is significantly different from that of steel workpieces. After the aluminum profile is pressed, bent and milled, it is necessary to quickly and accurately determine whether the contour size and hole processing size can meet the assembly requirements, which is a problem that needs to be considered by quality inspection technicians in the field. SUMMARY

[0003] The utility model discloses a kind of detection tools for the contour and partial position of automobile front anti-collision beam, and it is specially used for the detection of the outer contour and processing hole of front impact beam aluminum profile workpiece, with the advantages of quick and accurate detection, convenient operation etc.

[0004] To achieve the above object, the technical scheme of the utility model is as follows:

[0005] A detection tool for the contour and partial position of automobile front anti-collision beam, the base is provided with a bottom support and an end positioning plate at both ends, the bottom support supports the bottom surface of both ends of the workpiece, and the end positioning plate matches the edge line position of both ends of the workpiece; the rear side of the base is provided with a side contour plate A and a side contour plate B, which abut against the side edge of the workpiece; a side hole positioning pin is arranged on the side contour plate B, and the position of the side hole positioning pin matches the position of the side hole of the workpiece.

[0006] The side hole is a processing reference hole of the workpiece. After the side hole positioning pin is inserted into the side hole, the workpiece is placed on the tool for detection; a go-no-go gauge is swept through the gap between the end of the workpiece and the end positioning plate to determine whether the length of the workpiece meets the standard tolerance; the go-no-go gauge is swept through the gap between the edge of the workpiece and the side contour plate A and the side contour plate B to determine whether the horizontal straightness of the workpiece meets the standard tolerance.

[0007] Two fulcrums are arranged on the bottom supports at both ends. The fulcrums correspond to the corners of both ends of the workpiece.

[0008] The workpiece is supported by the fulcrums, and the main body of the workpiece is separated from the bottom support and the bottom hole gauge seat by a specific gap. The quality inspection personnel use the two heads of the go-no-go gauge to sweep the gap respectively. If the small head can be inserted into the gap and smoothly sweep through the gap, and the large head cannot be inserted into the gap, it is proved that the outer contour of the workpiece meets the tolerance requirement; otherwise, if one of them does not meet the requirement, it is proved that the outer contour of the workpiece does not meet the tolerance requirement.

[0009] The bottom hole gauge seat is provided with a plurality of through holes, and the positions of the through holes are matched with the positions of the bottom hole A and the bottom hole B of the workpiece.

[0010] The upper end face shape of the bottom hole gauge seat is matched with the bottom surface shape of the workpiece, and has the same function as the bottom support. When the workpiece is mounted, the hole gauge is inserted through the through hole, and it is detected whether the front end of the hole gauge can smoothly pass through the bottom hole A and the bottom hole B. If yes, it proves that the hole position processing is qualified.

[0011] The middle hole gauge pressing arm is connected to the middle hole of the workpiece through the column.

[0012] When the workpiece is placed, the pressing arm is pressed down, and the middle hole gauge is inserted into the middle hole. If yes, it proves that the middle hole processing is qualified.

[0013] The top pressing arm is connected to the top hole of the workpiece through the column.

[0014] The bottom surface shape of the top contour plate is matched with the top surface of the workpiece. After the top pressing arm is pressed down, the gap between the bottom surface of the top contour plate and the top surface of the workpiece is scanned by the two ends of the through gauge, and then the hole gauge is inserted into the through hole and the top hole. If yes, it proves that the top processing is qualified.

[0015] Advantages of the utility model

[0016] (1) The utility model is specially used for detecting the outer contour and the processing hole position of the automobile front anti-collision beam workpiece, and the shape and the size and position of the hole position of the workpiece are detected at the same time, so that the rapid and accurate detection of the workpiece is realized, and the production efficiency is greatly improved.

[0017] (2) The utility model has compact structure, small occupied area, convenient operation and convenient maintenance.

[0018] (3) The structure form and principle of the utility model can be further expanded, and are suitable for detecting other workpieces. DETAILED DESCRIPTION OF THE DRAWINGS
