Problems solved by technology
The rim side detection mechanism includes a three-axis linkage mechanism fixed on the side of the base and a scanning sensor fixed on the three-axis linkage mechanism. The scanning sensor detects the pressure deformation of the side surface of the rim, and the detection control device records the detection data output by the scanning sensor. , but the rim detection device with this structure can only measure the compression deformation of the side of the rim, and cannot measure the compression of the rim in the axial direction.

Embodiment Construction
[0025] The invention discloses a rim axial detection mechanism which can accurately measure the flatness of the rim and the shear strength of the rim steel wire. The second mounting part for the movement of the mounting part, the bearing mounting seat installed on the second positioning part, the bearing arranged on the bearing mounting seat, the servo motor, the spring, and the resistance ruler fixedly connected to one side of the second mounting part, wherein, The servo motor drives the bearing to move and makes the bearing contact with the rim. When the bearing meets the uneven contact surface of the rim, it will move. The bearing moves to drive the second mounting part and the guide rod to move. The guide rod moves to drive the spring to be stretched, and the resistance scale collects the bearing. When the contact surface of the rim returns to flatness, the elastic force of the spring drives the bearing back to the initial position. Through a resettable structure with a spr...

An axial testing mechanism for a rim comprises a seat, a first mounting element, a second mounting element, a bearing, a servo motor, a guide rod, a base, a spring and a resistance scale. One end of the guide rod is fixed with the second mounting element, and the other end of the guide rod is fixed with the base. Two ends of the spring are connected with the first mounting element and the base respectively. The servo motor drives the bearing to move and contacts the bearing with the rim, the bearing moves when the rim contact surface is not flat and drives the second mounting element and the guide rod to move, the guide rod moves to drive the spring to be tensioned, the resistance scale collects movement changing data of the bearing, and the spring force drives the bearing to return to the initial position when the rim contact surface recovers flatness. According to the axial testing mechanism for the rim, the flatness of the rim can be measured accurately through a reset structure with the spring and the resistance scale for collecting bearing bounce data, the structure is simple, and the measurement is accurate.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a wheel rim detection device. Background technique [0002] In the prior art, before the rim leaves the factory, the rim needs to be inspected for pressure deformation. Generally, pressure is applied manually or mechanically to rub the deformed rim shape, and check whether the rim is qualified by referring to the comparison table. The side of the ring can also be detected by the mechanical structure. [0003] In the prior art, there is a rim detection device for measuring the pressure on the side of the rim, which includes a test stand, which includes a base, a rotating platform fixed on the base, and a rim side detection mechanism. The middle part of the turntable is provided with toughened glass for placing the rim and a pressure driving mechanism capable of applying pressure to the rim. The middle part of the base is provided with an image measurement sensor and a detect...
