[0002] With the development of the aluminum alloy wheel industry, the manufacturing accuracy of aluminum alloy wheel products has been continuously improved, which has put forward higher requirements for wheel inspection methods. The existing wheel inspection fixture lacks the function of detecting the rim and contour. The detection of the wheel rim and contour can only be measured by a three-coordinate measuring machine, and the wheel hub needs to be manually moved to the measuring platform of the three-coordinate measuring machine for inspection, which has high labor intensity. During the inspection process, it is necessary to complete positioning, find the origin and other operations. The operation steps are cumbersome and the inspection efficiency is low, which cannot meet the inspection needs of fast-paced production. In addition, the three-coordinate measuring machine is occupied too much, which affects the timely inspection of other three-coordinate inspection items of the wheel hub.

[0003] Based on this, developing a hub profile inspection fixture for application in actual production is an urgent problem to be solved. Utility Model Content

[0004] The purpose of the utility model is to provide a hub profile inspection tool to solve the existing problems and solve the existing problems at the same time.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A wheel hub profile inspection tool comprises a ruler body, wherein the left end of the ruler body is fixedly connected to a ruler handle arranged corresponding to the outer rim of the wheel hub, the right side of the ruler body is slidably connected to a slide ruler arranged corresponding to the inner rim of the wheel hub, and the ruler body is provided with a measurement mark for indicating the rim width of the wheel hub to be inspected.

[0007] Preferably, the measurement mark is a circular mark hole opened on the ruler, and the aperture of the circular mark hole corresponds to the tolerance setting of the rim width.

[0008] Preferably, a plurality of the marking circular holes are arranged along the length direction of the ruler body, and are respectively arranged corresponding to wheel hubs of different specifications to meet the detection requirements of rim widths of different wheel types.

[0009] Preferably, wheel rim detection parts are respectively provided on the ruler handle and the slide ruler corresponding to the inner and outer wheel rims, for detecting the inner and outer wheel rims of the wheel hub.

[0010] Preferably, the wheel rim detection unit comprises a height scale for setting the wheel rim height dimension, and the height scale comprises a height through gauge set corresponding to the upper tolerance of the wheel rim height dimension, and a height stop gauge set corresponding to the lower tolerance of the wheel rim height dimension.

[0011] Preferably, the wheel rim detection unit comprises a thickness scale for detecting the wheel rim thickness, and the thickness scale is arranged corresponding to the end faces of the inner and outer wheel rims of the wheel hub.

[0012] Preferably, the wheel rim detection unit comprises an arc scale for detecting the arc radius of the inner and outer wheel rims, and the arc of the arc scale is set corresponding to the upper arc of the inner and outer wheel rims.

DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 1-3 As shown, a wheel hub profile inspection tool comprises a ruler body 1, the left end of the ruler body 1 is fixedly connected to a ruler handle 2 arranged corresponding to the outer rim of the wheel hub, and the right side of the ruler body 1 is slidably connected to a slide ruler 3, and the slide ruler 3 is arranged corresponding to the inner rim of the wheel hub. A measurement mark 11 is arranged on the ruler body 1 to indicate whether the rim width of the wheel hub being inspected is qualified.

[0023] During detection, if Figure 2 As shown, place the wheel hub vertically, hold the ruler body 1 so that the ruler handle 2 is fixed on the outer rim of the wheel hub, slide the slider 3 horizontally so that the right end of the slider 3 is fixed on the inner rim of the fixed wheel hub, and complete the installation of the inspection fixture. At this time, look at the position of the corresponding measurement mark 11 on the left end of the slider 3 to determine whether the wheel hub rim width is qualified. The slider 3 slidably connected to the ruler body 1 can be adjusted on the ruler body 1 to meet the requirements of wheel hubs with different rim widths for inspection.

[0024] Preferably, the measurement mark 11 is a marking circular hole 12 opened on the ruler body 1, and the aperture of the marking circular hole 12 corresponds to the tolerance setting of the rim width. During the inspection, the position of the marking circular hole 12 corresponding to the left end of the slide ruler 3 can be observed horizontally to determine whether the rim width size of the wheel hub being inspected is qualified. If the left end of the slide ruler 3 is aligned with the diameter range of the marking circular hole 12, it indicates that the rim width size of the wheel hub being inspected is qualified; if the left end of the slide ruler 3 is not aligned with the marking circular hole 12, it indicates that the rim width size of the wheel hub being inspected is unqualified. This embodiment uses the marking circular hole 12 as the measurement mark 11 to facilitate the inspection personnel to quickly identify the measurement mark 11, eliminates the trouble of specific readings, and improves the inspection efficiency.

[0025] The marking circular holes 12 are arranged in a plurality along the length direction of the ruler body 1 and are respectively arranged corresponding to wheel hubs of different specifications to meet the detection requirements of rim widths of different wheel types and improve the applicability of the inspection tool.

[0026] As a preferred embodiment, the ruler handle 2 and the slide ruler 3 are provided with wheel rim detection parts 4 corresponding to the inner and outer wheel rims, respectively, for detecting the inner and outer wheel rims of the wheel hub.

[0027] Preferably, the rim detection unit 4 includes a height scale 41 for setting the rim height dimension, and the height scale 41 includes a height through gauge 411 corresponding to the upper tolerance setting of the rim height dimension, and a height stop gauge 412 corresponding to the lower tolerance setting of the rim height dimension. During detection, the height through gauge 411 and the height stop gauge 412 of the rim detection unit 4 are respectively fixed between the inner and outer rims to perform rim height detection. If there is a certain gap between the upper edge of the height through gauge 411 and the upper edges of the inner and outer rims, and at the same time, the upper edge of the height stop gauge 412 is completely in contact with the upper edges of the inner and outer rims, and there is a certain gap between the lower edge of the height stop gauge 412 and the tire bead seat, then the inner and outer rim heights of the inspected wheel hub are determined to be qualified. Otherwise, it is unqualified. This embodiment completes the quick detection of the wheel hub rim height through the detection method of the stop gauge, which greatly improves the hub detection efficiency.

[0028] Preferably, the wheel rim detection unit 4 includes a thickness scale 42 for wheel rim thickness detection, and the thickness scale 42 is arranged corresponding to the end faces of the inner and outer wheel rims of the wheel hub. During detection, the wheel rim detection unit 4 is clamped between the inner and outer wheel rims. If the end faces of the inner and outer wheel rims protrude from the thickness scale 42 or the two are flush, the wheel rim thickness size of the inspected wheel hub is determined to be qualified; if the end faces of the inner and outer wheel rims are recessed in the thickness scale 42, it is determined to be unqualified.

[0029] Preferably, the wheel rim detection unit 4 includes an arc scale 43 for detecting the arc radius of the inner and outer wheel rims, and the arc scale 43 is set corresponding to the upper arc of the inner and outer wheel rims. During the detection, the wheel rim detection unit 4 is clamped between the inner and outer wheel rims, so that the arc scale 43 corresponds to the upper arc of the inner and outer wheel rims, and the arc scale 43 is horizontally observed to see whether it fits the upper arc of the inner and outer wheel rims to determine whether the wheel rim arc size is qualified. If the arc scale 43 fits the upper arc of the inner and outer wheel rims completely, or there is a gap of less than 0.5mm in the middle of the arc, it is determined that the arc radius size of the inner and outer wheel rims of the inspected wheel hub is qualified; if the arc scale 43 fits the middle of the upper arc of the inner and outer wheel rims and there is a gap at both ends, it indicates that the wheel rim arc radius of the inspected wheel hub is too small and is determined to be unqualified.

[0030] Preferably, if Figure 3 As shown, a slide groove 31 is provided on the slide ruler 3 corresponding to the ruler body 1, and the slide groove 31 is slidably connected to the ruler body 1. A cover 32 is buckled on the slide groove 31, and the cover 32 is connected and fixed to the slide ruler 3 by a fastening bolt 33.

[0031] The above disclosure is only a specific embodiment of the present patent, but the present patent is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, the deformation made should be deemed to belong to the protection of the present invention.
