[0002] The current rim inspection is to detect the hub end diameter runout value by locating the spoke center hole after the rim and spoke are integrated. The inspection method is basically in the product terminal process. If the rim processing is unqualified, the terminal inspection is unqualified and cannot be repaired, the product will be scrapped. There is a lack of intermediate process inspection, and the production quality of the rim cannot be fully guaranteed.

[0003] Therefore, designing a rim end runout detection device that can quickly detect the rim runout and fully ensure the production quality of the rim is an urgent problem to be solved. Utility Model Content

The circumferential rotation of the three-claw chuck mechanism can ensure that the diameter runout detector performs complete diameter runout detection in the circumferential direction of the rim. At the same time, the matching of the centering clamping mechanism and the telescopic claws can meet the diameter runout detection of rims of different specifications. The detection device is used alone to increase the detection process in the rim production process, which is conducive to ensuring the rim production quality and provides a quality assurance for the overall production process of the hub.

[0024] Please refer to Figure 1The embodiment of the present application provides a rim end radial runout detection device, including a detection platform 01, a three-jaw chuck mechanism 02, a centering clamping mechanism 03 and a radial runout detection mechanism 04; the three-jaw chuck mechanism 02 is rotatably arranged on the detection platform 01; the centering clamping mechanism 03 is arranged on the detection platform 01 at intervals around the three-jaw chuck mechanism 02; the centering clamping mechanism 03 is adapted to the position of the telescopic claw 24 of the three-jaw chuck mechanism 02, and the centering clamping mechanism 03 is connected to the telescopic claw 24; the radial runout detection mechanism 04 is arranged on one side of the detection platform 01.

[0025] The rim end diameter runout detection device achieves accurate fixation of the rim to be detected through the matching of the telescopic claw 24 of the three-claw chuck mechanism 02 and the centering clamping mechanism 03. The circumferential rotation of the three-claw chuck mechanism 02 can ensure that the diameter runout detector performs complete diameter runout detection in the circumferential direction of the rim. At the same time, the matching of the centering clamping mechanism 03 and the telescopic claw 24 can meet the diameter runout detection of rims of different specifications. The detection device alone increases the detection process in the rim production process, which is conducive to ensuring the quality of rim production and provides a quality assurance for the overall production process of the wheel hub.

[0026] Among them, the three-jaw chuck mechanism 02 includes a rotating shaft 21, an installing bearing 22, a turntable 23 and a telescopic claw 24; the rotating shaft 21 is rotatably set on the detection platform 01; the turntable 23 is sleeved on the rotating shaft 21; the installing bearing 22 is sleeved on the rotating shaft 21 and is located between the turntable 23 and the detection platform 01; the telescopic claw 24 is circumferentially spaced around the rotating shaft 21, and the telescopic claw 24 is connected to the rotating shaft 21 for movement along the radial direction of the rotating shaft 21.

[0027] The centering clamping mechanism 03 includes a clamping block 31, a connecting and mounting platform 32, a moving slider 33 and a fixed slide rail 34; the fixed slide rail 34 is arranged on the detection platform 01, and the track direction of the fixed slide rail 34 is along the radial direction of the rotating shaft 21; the moving slider 33 is slidably arranged on the fixed slide rail 34; the connecting and mounting platform 32 is fixedly arranged on the moving slider 33, and the side of the connecting and mounting platform 32 close to the rotating shaft 21 is connected to the telescopic claw 24; the clamping block 31 is fixedly arranged on the connecting and mounting platform 32.

[0028] The clamping block 31 includes a supporting seat and a supporting wall; the supporting seat is fixedly arranged on the connecting mounting platform 32; the supporting wall is arranged on the side of the supporting seat away from the rotating shaft 21, and the height of the supporting wall relative to the connecting mounting platform 32 is not less than the height of the supporting seat relative to the connecting mounting platform 32.

[0029] Due to the high height of the abutting wall, when the three-jaw chuck mechanism 02 drives the telescopic grip to retract, the abutting wall moves radially toward the axis of the rotating shaft 21 under the drive of the connecting mounting platform, thereby achieving stable clamping of the rim. The turntable 23 can ensure flatness, and is equipped with a fixed slide rail 34 and the transmission of the three-jaw chuck mechanism 02 to ensure that the clamping block 31 is synchronously opened and tightened with a repetitive accuracy within 0.03mm, thereby meeting the rim detection standard.

[0031] It also includes a telescopic foot 11, which is arranged on one end of the testing platform 01 away from the three-jaw chuck mechanism 02. The telescopic foot 11 can be adapted to different ground surfaces to ensure the stability of the test.

[0032] In summary, the embodiments provided by the present invention have the following main effective effects:

[0033] The rim end diameter runout detection device achieves accurate fixation of the rim to be tested through the matching of the telescopic claw 24 of the three-claw chuck mechanism 02 and the centering clamping mechanism 03. The circumferential rotation of the three-claw chuck mechanism 02 can ensure that the diameter runout detector performs complete diameter runout detection in the circumferential direction of the rim. At the same time, the matching of the centering clamping mechanism 03 and the telescopic claw 24 can meet the diameter runout detection of rims of different specifications. The detection device alone increases the detection process in the rim production process, which is conducive to ensuring the quality of rim production and provides a quality assurance for the overall production process of the hub.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
