Description

Technical Field

[0001] This utility model relates to the field of steering knuckle inspection tools, specifically a special inspection tool for steering knuckles. Background Technology

[0002] A steering knuckle gauge is a specialized measuring tool used to inspect whether various parameters of an automotive steering knuckle meet design requirements. The steering knuckle is a critical component of the automotive steering system, and its quality directly affects the safety and accuracy of steering. The steering knuckle gauge can accurately inspect the dimensional, shape, and positional accuracy of the steering knuckle, ensuring the stability of its quality during the production process.

[0003] Existing steering knuckle inspection fixtures are typically designed and manufactured for steering knuckles of specific vehicle models. Steering knuckles from different models vary significantly in shape, size, structure, and precision requirements. For example, the steering knuckles of passenger cars differ greatly in size and load-bearing capacity from those of heavy-duty trucks. This means that a single steering knuckle inspection fixture is often only suitable for inspecting steering knuckles from one or a few similar vehicle models. When inspecting steering knuckles from new vehicle models, it may be necessary to redesign and manufacture the fixture, reducing the calibration efficiency of the device. Therefore, we propose a dedicated steering knuckle inspection fixture. Utility Model Content

[0004] The purpose of this invention is to provide a dedicated steering knuckle inspection tool to address the problem mentioned in the background section that existing steering knuckle inspection tools are typically designed and manufactured for steering knuckles of specific vehicle models. Steering knuckles from different vehicle models vary significantly in shape, size, structure, and precision requirements. For example, the steering knuckles of passenger cars differ greatly in size and load-bearing capacity from those of heavy-duty trucks. This results in a steering knuckle inspection tool often only being applicable to the inspection of steering knuckles from one or a few similar vehicle models. When it is necessary to inspect steering knuckles from new vehicle models, it may be necessary to redesign and manufacture the inspection tool, reducing the calibration efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special inspection tool for steering knuckles, comprising: a main board, a calibration mechanism fixedly connected to the top of the main board, and an adjustment mechanism fixedly connected inside the main board.

[0006] The calibration mechanism includes a connecting rod fixedly connected to the top of the motherboard, a cylinder fixedly connected to the top of the connecting rod, a connecting plate fixedly connected to the bottom of the cylinder, a horizontal plate fixedly connected to the bottom of the connecting plate, a calibration plate fixedly connected to the bottom of the horizontal plate, and a fixing plate fixedly connected to one side of the connecting plate.

[0007] The bottom of the fixed plate is fixedly connected to a telescopic rod, the bottom of the telescopic rod is slidably connected to a retractable rod, and the retractable rod is fixedly connected to the top of the main board.

[0008] The adjustment mechanism includes a calibration hole fixedly connected inside the motherboard. A mounting plate is fixedly connected to one side of the calibration hole. A mounting bracket is fixedly connected to the periphery of the mounting plate. A threaded cylinder is fixedly connected to the bottom of the mounting bracket. A threaded rod is installed in the internal thread of the threaded cylinder.

[0009] The top of the threaded rod is fixedly connected to a turntable, and the outer periphery of the turntable is provided with anti-slip texture.

[0010] The motherboard has a support rod fixedly connected to its bottom, and a support base is fixedly connected to the bottom of the support rod.

[0011] One end of the motherboard is fixedly connected to an operating console, one end of the operating console is fixedly connected to a display screen, and one side of the display screen is fixedly connected to operating buttons.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, this invention features a calibration mechanism that allows operators to raise and lower the horizontal plate and calibration plate via a cylinder. The steering knuckle can then be calibrated and inspected through the calibration plate. The device also allows for reciprocating calibration via a telescopic rod, enhancing ease of use. An adjustment mechanism allows for calibration of the steering knuckle through a calibration hole. Furthermore, rotating a turntable rotates a threaded rod inside a threaded cylinder, allowing the calibration hole to be replaced by rotating the threaded rod out of the mounting bracket. This facilitates calibration of steering knuckles of different specifications, further improving the device's usability. Attached Figure Description
