Description

Technical Field

[0001] This utility model relates to the field of automotive component manufacturing and inspection technology, specifically a tooling for detecting the contour and hole positions of aluminum workpieces in the rear section of the rear floor side beam of an automobile. Background Technology

[0002] The rear floor side beam, located at the edge of the car chassis, enhances the vehicle's body strength and connects the chassis to the side skirts. Traditionally, the rear section of the rear floor side beam is made of steel. However, with the development of lightweight vehicles, aluminum alloy materials are increasingly being used to replace it, particularly aluminum profiles. The multi-cavity aluminum profiles provide structural rigidity while significantly reducing the weight of the rear floor side beam. The cross-section has two cavities, one of which has a connecting flange on one side.

[0003] Inspecting the outer contour of the rear section aluminum component of the rear floor side beam in automobiles is typically cumbersome. Because this component is not a regular shape, various inspection tools are required, such as inspection platforms, feeler gauges, hole gauges, and contour gauges, to inspect multiple surfaces. This process is complex and consumes a significant amount of time and effort from quality inspectors, especially when the inspection frequency is high, resulting in extremely low efficiency. Furthermore, due to the presence of protruding edges, the aluminum workpiece requires specially shaped supports with grooves to ensure stable placement. Therefore, improving the inspection efficiency and reducing the difficulty of inspecting the rear section aluminum workpiece of the rear floor side beam in automobiles is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this utility model is to provide a tooling for detecting the contour and hole positions of aluminum workpieces in the rear section of automotive rear floor side beams. It is specifically used for detecting the outer contour and machined hole positions of aluminum workpieces in the rear section of automotive rear floor side beams, and has the advantages of fast and accurate detection and convenient operation.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A fixture for detecting the contour and hole positions of an aluminum workpiece in the rear section of a car rear floor side beam includes: a base plate with a reference positioning pin whose position matches the reference machining hole on the workpiece; a raised edge support plate on one side of the base plate, matching the position of the raised edge on the workpiece; a side profile gauge on one side of the base plate, the shape of which matches the side contour shape of the workpiece; several downward quick clamps and side quick clamps on both sides of the base plate; a rear support at the rear end of the base plate, a swing arm at the top of the rear support, and a top profile gauge installed at the end of the swing arm, forming a gap between the top profile gauge and the top surface of the workpiece.

[0007] Use a standard gauge to scan the gap between the top and side profile gauges and the workpiece. If the larger end cannot enter the gap, but the smaller end can, it proves that the side profile of the workpiece meets the processing requirements.

[0008] The downward quick clamp and the side quick clamp anchor and clamp the workpiece's XY horizontal displacement and Z vertical displacement respectively to prevent it from loosening and affecting the detection.

[0009] The rear support is laterally inserted with a rear guide rod, and a rear movable guide rod is installed at the end of the rear guide rod. The rear movable guide rod forms a gap with the edge of the rear end face of the workpiece. A front fixed guide rod is set at the corresponding position on the front end face of the workpiece, and the front fixed guide rod forms a gap with the edge of the front end face of the workpiece.

[0010] The rear movable gauge, together with the front fixed gauge, ensures the inspection of the outer contour of the other side of the profile. The gap between the gauge and the workpiece is swept by a standard gauge. If the large end cannot enter the gap, but the small end can, it proves that the side contour of the workpiece meets the processing requirements.

[0011] The base plate is equipped with several bottom spring gauges, whose positions match the machining holes on the bottom surface of the workpiece. If the bottom spring gauges can be pressed down by hand and pass smoothly through the machining holes on the bottom surface of the workpiece, it proves that the machining holes on the bottom surface meet the machining size requirements.

[0012] A vertical gauge fixing plate is provided at the front end of the base plate, and several front spring gauges are installed on the gauge fixing plate. If the front spring gauges can pass smoothly through the machined holes on the front end face of the workpiece when pressed down by hand, it proves that the machined holes on the front end face meet the machining size requirements.

[0013] The top guide is equipped with several top hole gauges, the positions of which match the machining holes on the top of the workpiece. If the hole gauges can be smoothly inserted into the machining holes on the top surface of the workpiece, it proves that the machining holes on the top surface meet the machining size requirements.

[0014] The tooling usage method is as follows:

[0015] (1) Place the workpiece into the fixture from top to bottom, with the bottom surface supported by the base plate, and the reference positioning pin is embedded in the reference hole of the workpiece;

[0016] (2) Tighten the downward quick clamp and the side quick clamp;

[0017] (3) The quality inspector uses both ends of the standard gauge to scan the gap between the workpiece and each gauge. If the large end of the standard gauge cannot be inserted into the gap, but the small end of the standard gauge can be inserted into the gap, it proves that the surface contour (torsion, curvature) of the workpiece meets the processing requirements; otherwise, it proves that the surface contour of the workpiece is unqualified.

[0018] (4) If the quality inspector presses down or inserts the hole gauge on each face, and it can pass smoothly through the machined holes on each face of the workpiece, it proves that the machined holes on each face meet the machining size requirements.

[0019] Advantages of this utility model:

[0020] (1) This utility model is specifically used for the detection of the outer contour and machining hole of the aluminum workpiece in the rear section of the rear floor beam of automobile. It mainly performs one-time detection of the outer contour and machining hole of the workpiece, and the detection efficiency is high.

[0021] (2) This utility model has a compact structure, occupies a small area, is easy to operate and maintain.

[0022] (3) The structure and principle of this utility model can be further expanded to adapt to the detection of other workpieces. Attached Figure Description
