[0002] As an important component related to the safe driving of automobiles, the wheel hub plays a vital role in the safety of drivers and vehicles. Therefore, during the production and manufacturing process of the wheel hub, the size inspection of the wheel hub is extremely strict. The flange flatness of the forged wheel hub is prone to out-of-tolerance problems after milling, which leads to abnormal noise after the wheel hub is installed on the vehicle, affecting the driving experience of the whole vehicle. For the routine inspection of the wheel hub flange flatness, three-coordinate equipment is currently used for inspection. The operation steps are cumbersome, the overall inspection is time-consuming, and the inspection efficiency is low.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-4 As shown, a portable hub flange flatness detection device comprises a frame 1, on which a plurality of measuring arms 2 are arranged in a central array, and a measuring gauge 3 is arranged on the measuring arm 2 corresponding to the end face of the hub flange, for measuring the flatness data of the hub flange. A positioning mandrel 4 is arranged at the center of the frame 1 corresponding to the center hole of the hub flange, and the positioning mandrel 4 is rotatably connected to the center hole of the hub flange, so that the frame 1 can rotate relative to the hub flange with the mandrel as the axis, thereby driving the measuring gauge 3 to complete the flatness measurement of the end face of the hub flange.

[0022] When in use, the positioning mandrel 4 of the detection device is inserted into the center hole of the hub flange to be inspected, the measuring arm 2 is rotated, the measuring gauge 3 is driven to slide on the cross section of the hub flange, and the flatness data of the end face of the hub flange to be inspected is measured by the reading change of the measuring gauge 3. This embodiment provides a convenient flatness measurement method. The operator only needs to hold the measuring device and place it on the hub flange to complete the detection of the hub flange plane, overcoming the problems of cumbersome operation steps and low detection efficiency in traditional three-coordinate detection. At the same time, the on-site detection measurement method eliminates the trouble of carrying the three-coordinate system on the hub and reduces the labor intensity of the operator.

[0023] As a preferred embodiment, the fitting clearance between the positioning mandrel 4 and the center hole of the hub flange is controlled between 0.04-0.08 mm. While ensuring that the positioning mandrel 4 can smoothly penetrate the center hole of the hub flange, the fitting clearance between the positioning mandrel 4 and the center hole of the hub flange is minimized to ensure measurement accuracy.

[0024] As a preferred embodiment, the positioning mandrel 4 is detachably connected to the seat frame 1 to facilitate the replacement of the positioning mandrel 4, and the positioning mandrel 4 is configured with a variety of specifications corresponding to different types of hub flanges. When the positioning mandrel 4 is worn or accidentally damaged due to long-term use, the positioning mandrel 4 can be easily removed from the seat frame 1, and a new positioning mandrel 4 can be replaced to ensure the measurement accuracy. At the same time, when measuring the flatness of hub flanges of different models, the positioning mandrel 4 of the corresponding specifications can be replaced to quickly measure the flatness of different hub flanges. Preferably, the positioning mandrel 4 is threadedly connected to the seat frame 1. This embodiment enables the detection device to have a certain degree of versatility, eliminates the trouble of separately making a detection device for each type of hub flange, and reduces the production and management costs of on-site inspection tools.

[0025] Preferably, if Figure 2-3 As shown, the measuring gauge 3 is movably connected to the measuring arm 2, so that the radial position of the measuring gauge 3 on the end face of the hub flange can be adjusted, so that different radial positions of the end face of the hub flange can be measured. Specifically, a vertical long hole 21 penetrating the measuring arm 2 is provided on the measuring arm 2, and the measuring gauge 3 is slidably connected in the vertical long hole 21. By adjusting the position of the measuring gauge 3 in the long hole, the measurement of different radial positions of the end face of the hub flange can be achieved.

[0026] Preferably, the measuring scale 3 is connected to the measuring arm 2 through a clamping structure 5, so as to facilitate the position adjustment operation of the measuring scale 3. Specifically, the clamping structure 5 includes a slider for holding the measuring scale 3, the measuring arm 2 is a hollow tube, the slider is slidably connected to the inner cavity of the measuring arm 2, and the slider is composed of a positioning block 51 and a pressing block 52 which are separately arranged. The cylindrical grooves on the positioning block 51 and the pressing block 52 corresponding to the fixed rod 31 of the measuring scale 3 are used to clamp the measuring scale 3. A top plate 53 is provided in the inner cavity of the measuring arm 2 corresponding to the pressing block 52, and a through threaded hole is provided on the top plate 53. A sliding groove 55 for sliding connection of a pressing screw 54 is provided on the side wall of the measuring arm 2. The pressing screw 54 passes through the sliding groove 55, is screwed to the threaded hole, and is pressed against the pressing block 52. When in use, the pressing screw 54 is adjusted to make the top plate 53 press against the inner cavity of the measuring arm 2, thereby forming a pressing force on the fixed rod 31 of the measuring scale 3.

[0027] Preferably, the seat frame 1 is connected with a handle 6 for the operator to hold the detection device for measurement, and the handle 6 is screwed to the seat frame 1 .
