Embodiment Construction

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0032] It should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated structure. Those of ordinary skill in the art can understand the specific meanings of such terms in this patent according to specific situations.

[0033] Existing fixtures refer to Figure 4 , when the checker detects the axial and radial runout of the wheel, the wheel is installed on the turntable 101, and the turntable 101 is set in the vertical direction through the steel ball 102 in the limit ring and the bushing 103 to generate relative rotation and frict...

Abstract

The invention relates to the technical field of wheel production and manufacturing, in particular to a wheel radial and axial runout testing fixture which comprises a turntable, a rotating shaft and a supporting seat sequentially arranged from top to bottom in the vertical direction, wherein the supporting seat is of a hollow cylindrical structure; one end of the rotating shaft is connected with the turntable, and the other end extends into the supporting seat; and a plurality of bearings arranged in the vertical direction are arranged in the supporting seat. The beneficial effects are that in the process of detecting the radial and axial runout of the wheel, the central position of the rotating shaft is fixed through the cooperation of the bearing and the rotating shaft, so that the wheel can be effectively ensured to concentrically rotate along with the rotating disc and the rotating shaft without deviation; friction force in the rotating process of the rotating shaft is reduced through the bearing, abrasion between parts can be greatly reduced, and the rotating shaft can always keep stable measuring precision after long-term use.

Description

technical field [0001] The invention relates to the technical field of wheel manufacturing, in particular to a wheel radial and axial runout detection tool. Background technique [0002] The wheel is an important part of the vehicle driving system. The wheel is a rotating component that bears the load between the tire and the axle. It is usually welded by the combination of the two main components, the rim and the spokes. The radial and axial runout of automobile wheels is an important performance index used to measure the quality of wheel products. When the radial and axial swings of the car wheels are too large, the inertia generated will produce a huge periodic impact force with the increase of the vehicle speed, causing the wheels to bounce up and down, and the vibration will be transmitted to the whole vehicle through the suspension system. , Seriously affect the driving performance of the vehicle and the comfort of the driver and passengers. [0003] At present, the ...
