Description

Technical Field

[0001] The utility model relates to the technical field of casting part detection, and specifically, to a steering knuckle deformation inspection tool. Background Art

[0002] If dimensional deviation occurs during the production and processing of the steering knuckle, resulting in a too large thickness, it will be inconvenient for subsequent installation or processing, seriously affecting the overall quality of the product. The existing method for detecting the steering knuckle is to manually use a caliper to confirm one by one. This method is not only prone to false detection or missed detection caused by fatigue after long-term manual testing, but also requires a long time for manual processing, resulting in low overall detection efficiency.

[0003] Therefore, there is an urgent need to provide a steering knuckle deformation inspection tool to solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steering knuckle deformation inspection tool, which has a simple structure, is convenient to operate, is accurate and efficient in detection, and saves the cost of rework.

[0005] To achieve the above purpose, the utility model provides a steering knuckle deformation inspection tool, which includes a bottom plate and a support arm. A support block matching with the hub installation end on the steering knuckle is formed on the top end surface of the bottom plate. A first limit block matching with the tie rod ball pin installation end on the steering knuckle is formed on one side of the bottom plate. A pair of second limit blocks matching with the brake caliper installation end on the steering knuckle are formed on the other side of the bottom plate. The support arm is vertically arranged and a third limit block matching with the shock absorber installation end on the steering knuckle is provided at the top end; wherein,

[0006] The support block, the first limit block, the second limit block and the third limit block enclose a detection area so that the steering knuckle with qualified dimensions can smoothly pass through the detection area.

[0007] Preferably, the steering knuckle enters from the front end of the detection area and exits from the rear end.

[0008] Preferably, the difference between the inner diameter dimension of the detection area and the outer diameter dimension of the standard steering knuckle is less than or equal to 1 mm.

[0009] Preferably, pressure testers are provided on the support block, the first limit block, the second limit block and the third limit block. An alarm is connected to the pressure tester and is set to trigger the alarm when the pressure tester detects that the pressure exceeds a preset value.

[0010] Preferably, the alarm is an audible and visual alarm.

[0011] Preferably, the support block, the first limiting block, the second limiting block, the third limiting block and the support arm are all detachably mounted on the bottom plate.

[0012] According to the above technical solution, the inspection fixture designed by the present utility model uses the end face of the steering knuckle bearing mounting hole as the part support surface to detect and check the deformation of the steering knuckle casting in the two-dimensional X and Z directions. During the inspection, if the steering knuckle deforms, the part cannot pass through the inspection fixture smoothly. If the dimensions of the steering knuckle are qualified, it can pass through the inspection fixture smoothly to meet the production requirements. In this way, the deformed parts generated during the production transfer process can be effectively detected through simple visual recognition by humans, with high work efficiency and ensuring the qualification rate of the steering knuckle products.

[0020] The following will describe in detail the specific implementation of the present utility model with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present utility model and is not used to limit the present utility model.

[0021] In the present utility model, unless otherwise stated, the orientation terms such as "front, rear" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0022] See Figure 1 and Figure 2, the present utility model provides a steering knuckle deformation inspection tool. The steering knuckle deformation inspection tool includes a bottom plate and a support arm. A support block 1 that cooperates with the hub mounting end on the steering knuckle is formed on the top surface of the bottom plate. A first limit block 2 that cooperates with the tie rod ball pin mounting end on the steering knuckle is formed on one side of the bottom plate. A pair of second limit blocks 3 that cooperate with the brake caliper mounting end on the steering knuckle are formed on the other side of the bottom plate. The support arm is vertically arranged and a third limit block 4 that cooperates with the shock absorber mounting end on the steering knuckle is provided at the top; wherein,

[0023] The support block 1, the first limit block 2, the second limit block 3 and the third limit block 4 enclose a detection area so that the steering knuckle with qualified dimensions can smoothly pass through the detection area.

[0024] Through the above technical solution, the steering knuckle deformation inspection tool takes the end face of the steering knuckle bearing mounting hole as the part support surface to detect and check the deformation of the steering knuckle casting in the two-dimensional X and Z directions. During detection, if the steering knuckle is deformed, the part cannot smoothly pass through the inspection tool. If the dimensions of the steering knuckle are qualified, it can smoothly pass through the inspection tool to meet the production requirements. In this way, deformed parts generated during the production transfer process can be effectively detected through simple visual recognition by humans, with high work efficiency and ensuring the qualified rate of the steering knuckle products.

[0025] When using the steering knuckle deformation inspection tool for detection, in order to achieve standardized operation, enable the steering knuckle to correctly enter the inspection tool for detection, and avoid damage caused by collision between the two, preferably, the steering knuckle enters from the front end of the detection area and exits from the rear end.

[0026] In this embodiment, in order to constrain the dimensional requirements of the steering knuckle to be measured and ensure that its dimensions meet the subsequent processing and use requirements, preferably, the difference between the inner diameter dimension of the detection area and the outer diameter dimension of the standard steering knuckle is less than or equal to 1 mm.

[0027] When using the steering knuckle deformation inspection tool for detection for a long time, the fatigue of the human eye is likely to cause misdetection. Therefore, in order to better assist the inspector in deformation detection, preferably, pressure testers are provided on the support block 1, the first limit block 2, the second limit block 3 and the third limit block 4. An alarm is connected to the pressure tester and is set to trigger the alarm when the pressure tester detects that the pressure exceeds a preset value.

[0028] Furthermore, in order to make the alarm reminder of the steering knuckle deformation inspection tool more obvious and easier for the inspector to easily discover and reject the steering knuckle with unqualified dimensions, preferably, the alarm is an audible and visual alarm.

[0029] In addition, to enable the knuckle deformation inspection fixture to have better adaptability and be applicable to the deformation detection of various knuckles, preferably, the support block 1, the first limit block 2, the second limit block 3, the third limit block 4 and the support arm are detachably mounted on the bottom plate. In this way, the support block 1, the first limit block 2, the second limit block 3, the third limit block 4 or the support arm with different sizes or shapes can be replaced according to specific requirements during use.
