Description

Technical Field

[0001] This utility model relates to the field of wheel hub inspection technology, specifically a comprehensive rapid inspection tool for wheel hub insert holes. Background Technology

[0002] In automotive wheel hub quality inspection, window deformation and the positional accuracy of insertion holes (such as bolt mounting holes) are key indicators. Currently, the inspection of insertion holes mostly uses vernier calipers and coordinate measuring machines (CMMs). General-purpose measuring tools are inefficient and cannot comprehensively assess the positional accuracy and deformation of the holes; while CMMs offer high precision, their high cost and long turnaround time cannot meet the demands of 100% rapid full inspection on production lines. Therefore, there is an urgent need for a specialized inspection tool that is simple to operate, fast to inspect, provides intuitive results, and can comprehensively assess the quality of insertion holes. Utility Model Content

[0003] In view of this, the present invention aims to provide a comprehensive and rapid inspection tool for wheel hub insert holes, which can quickly, comprehensively, and intuitively determine whether wheel hub insert holes are qualified.

[0006] In some embodiments, the main body of the profiling fixture is machined based on the 3D modeling data of the wheel hub window, and the working contour surface is used to quantitatively evaluate the deformation clearance of the wheel hub window.

[0007] In some embodiments, the shape and size of the first guide post, the second guide post, and the third guide post are matched with the maximum physical boundary of the plug hole to be detected, and the end planes of the first guide post, the second guide post, and the third guide post constitute a reference plane for detecting the depth of the plug hole.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is for reference. Figures 1 to 3 The wheel hub insert hole integrated rapid inspection tool of this utility model is described in conjunction with the embodiments.

[0021] A comprehensive rapid inspection tool for wheel hub insert holes includes a contouring tool body 1. A first guide post 2, a second guide post 3, and a third guide post 4 are fixedly arranged below the contouring tool body 1. A weight reduction recess 5 is opened between the first guide post 2, the second guide post 3, and the third guide post to reduce the overall weight of the tool. An inspection handle 6 is installed at the center position above the contouring tool body 1. The working contour surface 7 of the contouring tool body 1 precisely matches the 3D shape of the wheel hub window to be inspected.

[0022] The main body 1 of the contour gauge is designed and manufactured based on the 3D modeling data of the wheel hub window. Its working contour surface serves as the inspection benchmark and is used to compare with the actual wheel hub window to quantitatively evaluate its deformation gap.

[0023] Below the main body of the conformal inspection fixture, a first guide post, a second guide post, and a third guide post are fixedly installed. The shape and size of the first guide post 2, the second guide post 3, and the third guide post 4 match the maximum physical boundary of the plug-in hole to be inspected, and their end planes form a reference plane for detecting the depth of the plug-in hole.

[0024] Weight-reducing recesses are created between the first, second, and third guide posts to significantly reduce the overall weight of the inspection tool, making it easier for operators to use for extended periods.

[0025] At the center of the upper part of the profiling fixture body 1, a testing handle 6 is fixedly installed by means of a threaded connection, providing a comfortable grip point for operation.

[0026] To ensure testing accuracy and safe use, the main body 1 of the profiling fixture is made of aluminum alloy. The surface roughness of its working contour surface is Ra≤1.6μm after precision machining, and all edges and surfaces must be free of burrs and flash.

[0027] A comprehensive rapid inspection tool for wheel hub insert holes includes a contouring tool body 1. A first guide post 2, a second guide post 3, and a third guide post 4 are fixedly arranged below the contouring tool body 1. A weight reduction recess 5 is opened between the first guide post 2, the second guide post 3, and the third guide post to reduce the overall weight of the tool. An inspection handle 6 is installed at the center position above the contouring tool body 1. The working contour surface 7 of the contouring tool body 1 precisely matches the 3D shape of the wheel hub window to be inspected.

[0028] The operator holds the inspection handle 6 of the inspection tool, aligns the working contour surface 7 of the main body 1 of the conforming inspection tool with the surface of the wheel hub window to be inspected, and gently places it on it. During this process, the first guide post 2, the second guide post 3, and the third guide post 4 set below the main body 1 of the conforming inspection tool will be aligned with the corresponding insertion holes on the wheel hub.

[0029] Once the fixture is in place, the window profile accuracy is judged by observing the fit between the working contour surface 7 of the fixture body 1 and the actual surface of the wheel hub window. If the gap between the working contour surface 7 of the fixture and the wheel hub window is uniform and small, within the allowable tolerance of the process, the wheel hub window profile is deemed qualified; if there is an obvious and uneven gap between the two, it indicates that the wheel hub window is deformed.

[0030] The insertion holes are inspected simultaneously. The diameter and position of each insertion hole are judged by whether the first guide post 2, the second guide post 3 and the third guide post 4 can be smoothly and without interference fully inserted into the corresponding insertion hole. After the guide post is fully inserted, the hole depth is judged by whether the end plane of each guide post is flush with the casting surface on the back of the wheel hub insertion hole.

[0031] After inspection, the operator can directly remove the gauge from the hub using the inspection handle 6 to proceed with the inspection of the next workpiece. The entire inspection process is simple and quick, and can be completed by a single person, effectively improving inspection efficiency and accuracy.

[0032] Compared with existing technologies, the hub insertion hole integrated quick inspection tool of this utility model has the following advantages:

[0033] 1. High inspection accuracy: The measuring parts of the inspection tool are completely determined by the 3D model of the product, and digital manufacturing ensures the absolute accuracy of the inspection benchmark; the requirement of surface roughness Ra≤1.6μm ensures the stability and consistency of the inspection.

[0034] 2. Integrated functions, high efficiency and portability: The integrated structure integrates window outline and plug hole position and depth detection functions, and a comprehensive judgment can be completed with one placement; the aluminum alloy material makes the inspection tool lightweight and easy to operate, which is very suitable for high-frequency use on the production line.

[0035] 3. Excellent craftsmanship and durability: All burrs and flash must be removed to avoid scratching the product or operators, reflecting the high quality and safety of the product.
