Description

Technical Field

[0001] This utility model relates to the field of steering knuckle inspection tools, and in particular to an automotive steering knuckle inspection tool. Background Technology

[0002] The steering knuckle is a key structural and load-bearing component in a car's steering system. Generally fork-shaped, it houses the kingpin and steering knuckle journal, connecting the wheels to the steering system to transmit and bear the loads from the front of the vehicle, supporting and driving the front wheels to rotate around the kingpin, thus enabling the car to steer. To ensure the safety and performance of the car's steering system, the steering knuckle needs to be inspected. However, existing steering knuckle inspection tools cannot fully utilize the shape of the steering knuckle during use, resulting in low positioning accuracy.

[0003] To address the aforementioned issues, patent document CN220428139U discloses an automotive steering knuckle inspection tool. This tool includes a main support base with a support frame at its bottom. The main support base has a steering knuckle center slot positioning and abutment assembly capable of reciprocating linearly in the vertical direction. The main support base also has a steering knuckle side fixing component capable of reciprocating linearly near or away from the steering knuckle center slot positioning and abutment assembly. The steering knuckle side fixing component and the steering knuckle center slot positioning and abutment assembly are staggered. In use, the steering knuckle center slot positioning and abutment assembly first passes through the center slot of the steering knuckle, securing them together. Then, the steering knuckle side fixing component is moved towards the side of the steering knuckle to ground-fix the side of the steering knuckle, thereby fully utilizing the shape of the steering knuckle and improving positioning accuracy.

[0004] However, although the aforementioned steering knuckle gauge can achieve precise positioning of the steering knuckle by utilizing its shape, it cannot directly inspect the mounting holes on various parts of the steering knuckle. Additional inspection tools are required for measurement, and different inspection tools need to be changed depending on the measurement of different mounting holes. This operation is cumbersome and greatly increases the time and labor costs of inspection. Utility Model Content

[0005] This utility model provides an automotive steering knuckle inspection tool to solve the technical problem that existing steering knuckle inspection tools cannot detect the mounting holes on the steering knuckle, requiring the use of other inspection tools for inspection, which is cumbersome and costly.

[0006] To solve the above problems, the automotive steering knuckle inspection tool provided by this utility model adopts the following technical solution:

[0007] An automotive steering knuckle inspection tool includes a base plate and a positioning structure and a detection structure mounted on the base plate;

[0008] The positioning structure includes a positioning seat and a shock-absorbing arm assembly installed on the side of the positioning seat.

[0014] 2. By installing a detection structure on the base plate, including a pin assembly, a tapered hole detection assembly, and a smooth hole detection assembly, the threaded holes, smooth holes, and tapered holes on the steering knuckle can be detected. During the inspection, it is only necessary to observe the insertion of the threaded hole pin, smooth hole pin, tapered hole detection pin, and smooth hole detection pin into the corresponding holes on the steering knuckle to determine whether the size, angle, position, and coaxiality of each hole on the steering knuckle meet the requirements. The operation is simple and does not require the use of additional inspection tools, effectively reducing the inspection cost of the steering knuckle.

[0015] Through the above-mentioned design, this utility model effectively solves the technical problem that the existing steering knuckle inspection tool cannot detect the mounting holes on the steering knuckle, requiring the use of other inspection tools for inspection, which is cumbersome and costly.

[0016] Furthermore, the positioning seat has a positioning boss at its center, and a plurality of positioning shafts are spaced apart on the outer periphery of the positioning boss.

[0017] Furthermore, the shock absorber arm base is provided with a pin mounting hole, and a bushing is provided inside the pin mounting hole, with the shock absorber arm pin inserted into the bushing.

[0018] Furthermore, the pin base includes a horizontal section and a vertical section. The vertical section is connected to the end of the horizontal section away from the positioning seat, and the angle between the vertical section and the horizontal section is an obtuse angle. The vertical section has pin mounting holes spaced vertically for mounting the threaded hole pin and the smooth hole pin.

[0019] Furthermore, a bushing is provided inside the pin mounting hole, and the threaded hole pin and the smooth hole pin are inserted into the bushing.

[0020] Furthermore, the number of the pin assemblies is two, namely the brake pipe mounting hole pin assembly and the ABS hole pin assembly.

[0021] Furthermore, the radial dimension of the threaded hole pin of the brake pipe mounting hole pin assembly is greater than the radial dimension of the smooth hole pin; the radial dimension of the threaded hole pin of the ABS hole pin assembly is smaller than the radial dimension of the smooth hole pin.

[0022] Furthermore, the conical hole base includes a horizontal section and a vertical section.

The vertical section is provided with a pin mounting hole for installing the conical hole pin, and a bushing for inserting the conical hole pin is provided in the pin mounting hole.

[0023] Furthermore, the positioning seat, the shock-absorbing arm base, the pin base, and the conical hole base can all be detachably mounted on the base plate.

[0024] Furthermore, the base plate has a mounting hole for mounting the optical aperture detection pin, a bushing is installed in the mounting hole, and the optical aperture detection pin passes through the bushing and extends vertically upward. Attached Figure Description
