Embodiment 1

[0037] Such as Figure 1-Figure 4 As shown, the steering knuckle detection device includes a first moving seat 10, the first moving seat 10 can move axially along the shaft portion 31 of the detected steering knuckle, and a light curtain sensor 11 is installed on the first moving seat 10, The light curtain sensor 11 faces the circumferential surface or the conical surface of the shaft portion 31 of the knuckle. Specifically, the first moving seat 10 is slidably mounted on a pair of guide rails 20 , and the extending direction of the guide rails 20 is the same as the axial direction of the shaft portion 31 of the steering knuckle to be detected. When it is necessary to measure different axial positions, it is sufficient to move the first movable seat 10 on the guide rail 20 . In addition, the first mobile seat 10 can be made into a gantry shape, which can improve the overall rigidity of the first mobile seat 10, reduce the deformation of the first mobile seat 10 due to unavoid...

Embodiment 2

[0052] This embodiment provides a steering knuckle detection method using the above steering knuckle detection device, such as Figure 5 As shown, the method includes a shaft detection step and a displacement step;

[0053] In the shaft portion detection step, use the light curtain sensor 11 to measure the radius of the shaft portion 31 during the 360° rotation of the steering knuckle along the shaft portion 31 to obtain the circular runout value, and / or use the surface runout detection sensor 12 to detect the end face runout value and circular runout value;

[0054] In the displacement step, the first moving seat 10 is moved along the linear direction of the shaft portion 31 to different positions of the shaft portion 31 .

[0055] That is, the steering knuckle is rotated 360° at an axial position, and the radius of the shaft section 31 is measured by the light curtain sensor 11 to obtain the circumferential runout value, and / or, the surface runout detection sensor 12 is use...

Abstract

The invention relates to the technical field of machining product detection, and particularly relates to a steering knuckle detection device and a steering knuckle detection method by using the steering knuckle detection device. The steering knuckle detection device comprises a first mobile seat; the first mobile seat can move axially along the axial part of a detected steering knuckle; a light curtain-type sensor is arranged on the first mobile seat; and the light curtain-type sensor faces the circumferential surface or the conical surface of the axial part of the steering knuckle. Thus, thetechnical problem of long measuring time in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of detection of machined products, in particular to a steering knuckle detection device and a steering knuckle detection method using the steering knuckle detection device. Background technique [0002] Automobile steering knuckle is one of the important components in the steering axle. It is a device that can make the car run stably and flexibly change the driving direction according to the driver's intention. The function of the steering knuckle is to transmit and carry the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the car is running, it bears variable impact loads, so it is required to have high strength. Therefore, after the production and processing of the steering knuckle, it is necessary to test its space, angle, and hole position to ensure that each product is qualified. [0003] At present, the measurement methods of automobile stee...
