Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts detection tool, concretely is shock tower hole position precision gauge. BACKGROUND

[0002] The shock tower is a top metal structural member installed on the automobile shock absorber, and the shock absorber and the shock spring of the suspension system are installed on the shock tower. As a key load-bearing component, the shock tower is mainly used for absorbing top impact and bearing force from the shock absorber spring, and plays a crucial role in the comfort and steering stability of the automobile.

[0003] The hole on the shock tower is a key part for installing the shock absorber, and the accuracy of the hole directly affects the installation position and angle of the shock absorber. If the accuracy of the hole is insufficient, it may cause deviation in the cooperation of the shock absorber with other components after installation, affecting the normal work of the shock absorber, reducing its buffering and damping effect, and further affecting the driving stability and comfort of the vehicle. In actual production, the detection of the shock tower usually adopts a special detection tool. For example, the prior art "a shock tower detection gauge" (publication number: CN222279563U) discloses a shock tower, which realizes detection of the relevant hole positions of the front end, middle end and rear end of the shock tower by setting multiple detection mechanisms. However, the existing technology still has the following technical problems:

[0004] The structure of the shock tower is complex, and the whole is in the shape of a upwardly convex shell. The existing technology can only detect the holes of the front end, middle end, top end and side end of the shock tower, but cannot detect the holes on the rib plate inside the concave part of the shock tower, which may lead to inaccurate position of the holes on the rib plate of the shock tower, affecting the connection stability of the shock tower and other components. With the increase of driving time and body vibration of the vehicle, the shock tower is prone to deformation or damage, even falling off, causing safety accidents. UTILITY MODEL CONTENTS

[0006] The present application provides the following technical scheme: a shock tower hole position precision gauge, comprising a mounting seat, a support table, a pressing unit and a detection unit fixed on the mounting seat respectively; a support plate is provided in the middle of the mounting seat, and the support table is located on the support plate; the pressing unit is located around the support table;

[0007] The detection unit comprises a rib plate hole detection mechanism under the support table, the rib plate hole detection mechanism comprises a support arm fixed on the support plate and in L shape, a detection rod slidingly connected to the upper end of the support arm, a locking nut threadedly connected to the end of the detection rod, and a compression spring sleeved on the rod portion of the detection rod, the two ends of the compression spring being located between the locking nut and the support arm, and the end of the detection rod away from the locking nut being a detection head, the diameter of the detection head being larger than the diameter of the rod portion of the detection rod.

[0008] Advantages:

[0009] 1. The detection comprehensiveness of the damping tower is improved, and the problem of insufficient connection stability of the damping tower is prevented. The rib plate hole detection mechanism is arranged below the support table, which can detect the structure holes inside the recess of the damping tower. When the damping tower is placed on the support table, the rib plate of the recess of the damping tower can be close to one side of the support table, and the side wall of the support table is in parallel with the surface of the rib plate of the damping tower, so that when the locking nut is actuated to push the detection head, the detection head can enter the rib plate hole vertically to detect the position accuracy, and the holes on the rib plate inside the recess of the damping tower which are difficult to detect are comprehensively detected, thereby the quality control of the damping tower is strengthened, and the connection stability of the damping tower is ensured.
