Description

TECHNICAL FIELD

[0001] The utility model relates to the field of auxiliary positioning mechanism, specifically is a kind of automobile steering knuckle size measuring device auxiliary positioning mechanism. BACKGROUND

[0002] Vehicle steering knuckle is one of the main parts on automobile steering axle, and it is the key pivot in vehicle steering system, which is an important component connecting wheel and vehicle suspension, and bears the steering responsibility in vehicle running, so that vehicle can change running direction flexibly. In the process of vehicle steering running, vehicle steering knuckle completes steering action of wheel by cooperating with vehicle steering drag link and vehicle steering arm component, so as to change the running direction of vehicle.

[0003] Since the size accuracy of vehicle steering knuckle mounting hole directly affects the steering performance and running stability of vehicle, the automobile steering knuckle needs to be accurately measured before being installed to vehicle. After production of vehicle steering knuckle, vehicle steering knuckle is usually placed on detection frame, and then size measuring device measures caliber of mounting hole on vehicle steering knuckle. In the detection process of vehicle steering knuckle, size measuring device drives probe by setting program, and probe performs contact high-precision measurement on mounting hole on vehicle steering knuckle. Probe transmits measurement result to size measuring device, and worker compares measurement value with standard value to determine whether produced vehicle steering knuckle part is qualified.

[0004] In the process of measuring size of vehicle steering knuckle, worker usually places measuring steering knuckle on placing frame. Since caliber of mounting hole is measured by contact high-precision measurement, vehicle steering knuckle may be offset after being touched by probe for many times, so that size measuring device has detection result error. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model aims at providing a kind of automobile steering knuckle size measuring device auxiliary positioning mechanism to solve the technical problem that probe touches vehicle steering knuckle for many times when size measuring device detects caliber of vehicle steering knuckle mounting hole, which causes position offset of vehicle steering knuckle.
