Description

Technical Field

[0001] The utility model relates to the technical field of automobile processing, in particular to a multi-hole precision rapid detection device for special-shaped aluminum workpieces. Background Art

[0002] In recent years, due to the requirement of lightweight, all parts of the whole vehicle have been made of aluminum. In particular, aluminum profiles have multiple closed cavities and are produced by hot extrusion. They have good rigidity and precise cross-sectional dimensions and are used in various beams of the vehicle body. The aluminum workpiece is connected to the chassis of the vehicle body through multiple connectors or bolt fasteners. First, the connection holes must be processed on the aluminum workpiece. The processing position and dimensional tolerance of the connection holes are strictly required, and the dimensional relationship between the various processed holes must also match and relate to each other, otherwise it will affect the subsequent assembly.

[0003] Usually, after the aluminum workpiece is processed, it needs to be placed on a check fixture for hole position detection. The traditional detection platform or tool has a low degree of integration, and multiple detection tools are used to detect the processed holes one by one. The detection efficiency is low, and the detection of the relative positions of the various processed holes is difficult. In particular, the shapes of workpieces vary, and there are many special-shaped processing holes on the workpieces, mixed with multiple circular processing holes. The number of processing holes is large and the shapes are different. Manual detection is very complicated, the workload is large, and it is easy to miss detection. Therefore, special inspection fixtures for special workpieces are very necessary. Although some integrated special detection devices are also recorded in the existing literature, for the rapid detection of special-shaped workpieces, the methods need to be flexible and changeable to achieve the effect of twice the result with half the effort. Summary of the invention

[0004] The utility model aims to provide a device for rapid detection of multiple holes of special-shaped aluminum workpieces, which adopts a sliding abutment seat to abut against the plane of the workpiece to detect its special-shaped holes, and other round holes are detected by hole gauges, and is supplemented by positioning mechanisms in horizontal and vertical directions to achieve the effect of rapid detection of special-shaped aluminum workpieces.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A device for rapid detection of multiple holes of a special-shaped aluminum workpiece is disclosed. A base is fixedly arranged on a platform, and the base includes a corner base and a main body base. The corner base corresponds to the corner part supporting the special-shaped aluminum workpiece, and the main body base corresponds to the main body of the special-shaped aluminum workpiece. A slide rail is also arranged on the platform, and a slidable sliding abutment seat is installed on the slide rail. A special-shaped protrusion matching the special-shaped processing hole of the special-shaped aluminum workpiece is arranged on the panel of the sliding abutment seat.

[0007] Since there are multiple special-shaped holes on the main plane of the special-shaped aluminum workpiece, traditional inspection methods are not applicable. Therefore, in this patent, a standard abutment inspection plate is pre-processed, and several special-shaped protrusions on the inspection plate completely correspond to the special-shaped holes of the aluminum workpiece and meet the tolerance requirements. When the special-shaped protrusions are successfully embedded in the special-shaped holes, the special-shaped processing holes of the aluminum workpiece are considered qualified.

[0008] Side positioning blocks are fixedly arranged on both sides of the base to abut against and position the two side walls of the special-shaped aluminum workpiece. The side positioning blocks are L-shaped, with the horizontal part fixed on the platform and the vertical part used to support and abut against the aluminum workpiece.

[0009] The platform is provided with a plurality of vertical clamping mechanisms, which are composed of manual quick clamps and a clamping block installed at the end of the clamp arm, to limit the up and down position of the aluminum workpiece.

[0010] The platform is provided with a horizontal clamping mechanism, which is composed of a manual quick clamp and a pressure head installed at the end of a pressure rod, to limit the horizontal position of the aluminum workpiece and clamp the aluminum workpiece together with the sliding abutment seat.

[0011] A plurality of hole gauges are placed on the base, and the hole gauges correspond to the circular holes on the aluminum workpiece one by one.

[0012] The method of using special-shaped workpieces includes the following steps:

[0013] A. Place the special-shaped aluminum workpiece on the base, with the corner corresponding to the corner base and the main body corresponding to the main body base; both sides of the special-shaped aluminum workpiece are positioned against the side positioning blocks;

[0014] B. Press the quick clamp of the vertical clamping mechanism down to clamp the upper end surface of the aluminum workpiece, and the quick clamp of the horizontal clamping mechanism presses the back of the aluminum workpiece to prevent the aluminum workpiece from moving freely;

[0015] C. Slide the sliding abutment seat against the plane of the special-shaped aluminum workpiece. If the multiple special-shaped protrusions of the sliding abutment seat can be exactly fitted into the multiple special-shaped holes of the aluminum workpiece, it is considered that the processing size and position of the special-shaped holes meet the requirements;

[0016] D. Use the hole gauge placed on the platform to inspect the circular holes of the aluminum workpiece one by one. If all the hole diameters meet the requirements, it is considered that the processing of the aluminum workpiece meets the requirements.

[0017] Advantages of utility models

[0018] After the special-shaped aluminum workpiece is clamped once, the sliding abutment seat with multiple special-shaped protrusions is used to perform a one-time abutment detection on the special-shaped holes on the special-shaped aluminum workpiece, which not only has high detection efficiency but also is accurate and has fewer detection steps.

[0019] The utility model does not need to hold a detection tool for detection, and the sliding detection saves effort and time, which can reduce the work intensity of the quality inspectors.

[0020] The utility model has a small overall volume, does not occupy space, and is convenient and quick to carry.

[0021] After the detection plate on the sliding abutment seat is replaced, the utility model can be suitable for the detection needs of other aluminum workpieces, and the application scope can be expanded arbitrarily. BRIEF DESCRIPTION OF THE DRAWINGS
