Perpendicularity testing tool of steering knuckle

Abstract

The invention discloses a perpendicularity testing tool of a steering knuckle. The perpendicularity testing tool of the steering knuckle comprises a support component, two support blocks, a core rod and a testing component, wherein the support component comprises a bottom plate and a support plate, a V-shaped groove is formed in each support block, the testing component comprises a measurement frame, a U-shaped clamp groove is formed in the measurement frame, and sensors are fixedly installed on the periphery of the U-shaped clamp groove. In use, the core rod passes through a main pine hole in the steering knuckle, and then the core rod together with the steering knuckle is placed on the V-shaped grooves in the support blocks, the support blocks limit four degrees of freedom of the steering knuckle, and then the measurement frame is slid until the U-shaped clamp groove clamps the core rod, and at the moment, each inward-opening gear corresponds to each sensor, and then signals of the sensors are collected, and therefore perpendicularity of planes of the inward-opening gears, relative to a main pin hole, can be evaluated, and then the signals of the sensors can be analyzed, and the width between planes of each two adjacent inward-opening gears is confirmed. Compared with the prior art, testing accuracy is substantially improved, and the perpendicularity testing tool of the steering knuckle is simple in structure, high in testing efficiency, and simple and reliable to operate.

[0002] The width of the inner opening of the steering knuckle and the perpendicularity between the two planes of the inner opening and the king pin hole with the bushing are the key indicators for the processing of the steering knuckle. The machining accuracy directly affects the steering system of the car. Generally, the machining is completed Finally, the detection of the above two parameters is required. At present, the commonly used method is to use three coordinates for detection. This method needs to make special fixtures to position and clamp the steering knuckle. However, the detection efficiency of three coordinates is low. The inspection procedure is cumbersome; the other three coordinates can only be inspected randomly. When the position accuracy is found to be unqualified, batch scrapping may have occurred

Finally, since there are many dense and irregular oil grooves in the bushing hole of the steering knuckle, the detection can only be completed by manually collecting the detection points one by one by the inspector when using the three-coordinate detection. Once a detection point is close to the oil groove or falls In the oil tank, the detection results will form a large error, which is not only inefficient, but also relatively error-prone
