Description

Technical Field

[0001] This utility model relates to the field of aluminum workpiece manufacturing and inspection technology, specifically a tooling for inspecting the shape of an aluminum workpiece connecting the front engine compartment of an automobile. Background Technology

[0002] The angle aluminum connecting nuts for the front engine compartment of an automobile are installed on the side beam of the front engine compartment. Several sleeve nuts are riveted onto the angle aluminum workpiece. During assembly, other components are installed onto the side beam of the front engine compartment via bolts at the sleeves. In the actual processing and use, the straightness and torsion of the angle aluminum workpiece are important indicators. Whether these indicators are qualified determines the subsequent assembly accuracy of the automobile. Therefore, it is essential to check the shape and position dimensions of the angle aluminum workpiece after processing.

[0003] Various tooling and fixtures are used in the inspection of angle aluminum workpieces. Traditional tooling and fixtures include inspection platforms, angle gauges, hole gauges, and feeler gauges. However, due to the large number of geometric dimensions that need to be inspected on the workpiece, it is very time-consuming to inspect each one individually using different fixtures. In addition, various accessories attached to the angle aluminum can also cause interference with the fixtures during inspection. Therefore, the design of dedicated inspection tooling for angle aluminum workpieces is a problem that needs to be considered by those skilled in the art. Summary of the Invention

[0004] The purpose of this utility model is to provide a tooling for inspecting the shape of aluminum angle workpieces connecting the front engine compartment of automobiles. It is specifically used for inspecting the aluminum angle nuts connecting the front engine compartment of automobiles and has the advantages of quick and convenient operation and high inspection accuracy.

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

[0006] A tooling for inspecting the shape of an aluminum angle workpiece connecting to the front engine compartment of an automobile has several base platforms on the base plate corresponding to one of the right-angled sides of the aluminum angle workpiece, and a side platform on one side of the base platforms corresponding to the other right-angled side of the aluminum angle workpiece. Several through holes are provided on the base platform and the side platform respectively, and a spring gauge is installed on each through hole to correspond to the machining hole position on the aluminum angle workpiece.

[0007] The included angle formed by the bottom platform and the side platform matches the included angle of the two right-angled sides of the angle aluminum workpiece. The spring gauge consists of a compression spring and a regular gauge with a handle. In the unused state, one end of the compression spring is fixed to the platform surface, and the other end is fixed to the handle. The gauge passes through the center hole of the compression spring and the through hole of the platform. In the used state, pressing the handle causes the gauge to overcome the resistance of the compression spring and pass into the machined hole of the angle aluminum workpiece. If the gauge is inserted smoothly, it proves that the position and size of the machined hole meet the requirements; if it cannot pass through, it proves that the position or size of the machined hole does not meet the requirements and the part is unqualified.

[0008] One end of the base platform is provided with an end post A, and a quick clamp A is fixedly installed on the top of the end post A. A through hole is provided on the end post A, and a horizontally movable pressure fork is inserted into the through hole. Several top blocks are provided on the base platform. The fork of the pressure fork matches the position of the top block and can be pressed into the middle of the pressure fork by the clamp of the quick clamp A.

[0009] The top block supports the four corners of the aluminum workpiece plane, creating a gap between the workpiece plane and the platform plane. The quality inspector will use both ends of a go gauge to check this gap. If the small end of the go gauge can pass through the gap but the large end cannot, it proves that the torsion and flatness of the aluminum workpiece are qualified; otherwise, it proves that the torsion and flatness of the aluminum workpiece are deviated.

[0010] Because the nuts or sleeves protruding on the angle aluminum workpiece interfere with the path of the pressure chuck, ordinary quick-clamp pressure chucks cannot be used here; instead, a movable pressure fork is used to approach the top block to be pressed horizontally from the end, and then the middle of the quick-clamp pressure fork is used to indirectly press the workpiece.

[0011] One end of the base platform is provided with an end post B, and a quick clamp B is fixedly installed on the top of the end post B. Several top blocks are provided on the base platform, and the fork-shaped pressure head of the quick clamp B matches the position of the top blocks.

[0012] For workpiece ends without assembled nuts or sleeves, quick-clamp fork-shaped chucks can be used to directly clamp the workpiece.

[0013] A positioning pin is provided on the bottom platform, and the position of the positioning pin matches the reference hole on the angle aluminum workpiece. The positioning pin securely and accurately positions the angle aluminum workpiece on the bottom platform.
