Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, in particular to a detection tool for determining the height of a ball pin mounting hole of an automobile steering knuckle. Background Technique

[0002] In the automobile manufacturing industry, the steering knuckle is a key component and an important part of the vehicle suspension system. It is also known as a wheel fork or a steering knuckle arm. It is located near the center of the wheel. Its main function is to connect the wheel and the suspension system, enabling the wheel to move vertically to adapt to road surface changes and allowing the wheel to rotate relative to the vehicle body during steering. It also plays a role in connecting other control structures, such as control arms and steering tie rods, and in transmitting the movement of the steering wheel to achieve wheel steering. Therefore, it is a crucial safety component for ensuring vehicle driving. Therefore, its design, manufacture, and inspection all need to follow strict standards. Currently, the measurement at the ball pin mounting hole generally uses a profiling inspection tool, and then visually determines whether the upper and lower limit plunger end faces of the profiling inspection tool exceed or are lower than the machined surface to judge whether the height from a specific virtual plane to the machined surface is qualified. However, this judgment method is prone to misjudgment due to inaccurate subjective judgment in critical value judgment. Content of the Utility Model

[0003] The utility model provides a detection tool for determining the height of a ball pin mounting hole of an automobile steering knuckle, which can solve the problem that the existing measurement at the ball pin mounting hole of the steering knuckle uses a profiling inspection tool, and then visually determines whether the upper and lower limit plunger end faces of the profiling inspection tool exceed or are lower than the machined surface to judge whether the height from a specific virtual plane to the machined surface is qualified, and the measurement result is prone to deviation in critical value judgment, resulting in inaccurate measurement results.

[0004] To achieve the above object, the utility model provides the following technical solution: A detection tool for determining the height of a ball pin mounting hole of an automobile steering knuckle, including a first inner surface spacing inspection tool jaw and a second inner surface spacing inspection tool jaw arranged oppositely, and the first inner surface spacing inspection tool jaw and the second inner surface spacing inspection tool jaw are connected by a handle; a first clamping groove is arranged on the outer side of the first inner surface spacing inspection tool jaw, a second clamping groove is arranged on the outer side of the second inner surface spacing inspection tool jaw, and a screw-shaped detection block is arranged in the first clamping groove or the second clamping groove. One end of the detection block is attached to the inner side wall of the first clamping groove or the second clamping groove, and the other end of the detection block is inserted into the ball pin mounting hole of the steering knuckle. By adopting a standard block and an accurate jaw design, the traditional visual judgment method is replaced by mechanical positioning and fixing devices, significantly reducing the error caused by the subjective judgment of the operator and improving the reliability of the measurement result.

[0005] Preferably, the detection block includes a measured plane positioning and mounting block that matches the ball joint mounting hole of the steering knuckle. A positioning block is provided on one side of the measured plane positioning and mounting block. The measured plane positioning and mounting block is inserted into the ball joint mounting hole of the steering knuckle, and the distance between the lower surface of the measured plane positioning and mounting block and the lower surface of the steering knuckle is the distance to be detected.

[0006] Preferably, the cross-section of the handle is polygonal, and threaded holes are provided on the opposite outer sides of the handle, which is convenient for processing.

[0007] Preferably, the cross-section of the handle is polygonal, and threaded holes are provided on the opposite outer sides of the handle, which is convenient for processing.

[0008] Preferably, through holes corresponding to the threaded holes are provided on the opposite inner sides of the first inner surface spacing gauge jaw and the second inner surface spacing gauge jaw.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0018] As Figures 1-4 shown, in order to solve the problem that the measurement at the ball pin mounting hole of the existing steering knuckle uses a profiling fixture, and then visually judges whether the two upper and lower limit plunger end faces of the profiling fixture exceed or are lower than the machined surface to judge whether the height from a specific virtual plane to the machined surface is qualified, and the measurement result is prone to deviation in the critical value judgment, resulting in inaccurate measurement results, the present utility model provides the following technical solutions: An inspection fixture for determining the height of the ball pin mounting hole of an automotive steering knuckle, including a first inner surface spacing inspection fixture jaw 1 and a second inner surface spacing inspection fixture jaw 2 arranged oppositely, and the first inner surface spacing inspection fixture jaw 1 and the second inner surface spacing inspection fixture jaw 2 are connected by a handle 3; a first clamping groove 11 is arranged on the outer side of the first inner surface spacing inspection fixture jaw 1, a second clamping groove 21 is arranged on the outer side of the second inner surface spacing inspection fixture jaw 2, and a screw-shaped detection block 4 is arranged in the first clamping groove 11 or the second clamping groove 21. One end of the detection block 4 is attached to the inner side wall of the first clamping groove 11 or the second clamping groove 21, and the other end of the detection block 4 is inserted into the ball pin mounting hole of the steering knuckle 5. By adopting a standard block and an accurate jaw design, the traditional visual judgment method is replaced by mechanical positioning and fixing devices, significantly reducing the error caused by the subjective judgment of the operator and improving the reliability of the measurement result.

[0019] In this embodiment, as Figure 3 shown, the detection block 4 includes a measured plane positioning and mounting block 41 matching the ball pin mounting hole of the steering knuckle 5. A positioning block 42 is arranged on one side of the measured plane positioning and mounting block 41. The measured plane positioning and mounting block 41 is inserted into the ball pin mounting hole of the steering knuckle 5, and the lower surface of the measured plane positioning and mounting block 41 and the lower surface of the steering knuckle 5 are the distances to be detected.

[0020] In this embodiment, as Figure 3 shown, a slot 43 is arranged on one side of the measured plane positioning and mounting block 41 close to the positioning block 42, which is convenient for processing.

[0021] In this embodiment, as Figure 1 shown, the cross section of the handle 3 is polygonal, and threaded holes 31 are arranged on the opposite outer sides of the handle 3, which is convenient for processing.

[0022] In this embodiment, as Figure 2As shown, through holes 12 corresponding to the threaded holes 31 are provided on the relative inner sides of the first inner surface spacing gauge jaws 1 and the second inner surface spacing gauge jaws 2. Fasteners pass through the through holes 12 and are connected to the threaded holes 31, which is convenient for installation.

[0023] In this embodiment, as Figures 1-4 shown, first, insert the measured plane positioning and mounting block 41 of the detection block 4 into the ball pin mounting hole of the measured steering knuckle 5. The ball pin mounting hole of the measured steering knuckle 5 is in the shape of a tapered hole or a round hole. The first clamping groove 11 of the first inner surface spacing gauge jaw 1 is clamped on the upper side of the measured plane positioning and mounting block 41 and the lower surface of the measured steering knuckle 5, and the first clamping groove 11 is pushed in by fitting the upper surface of the measured plane positioning and mounting block 41. If it can be completely inserted, it means that the measured dimension is below the upper limit height, and it is judged to be qualified. If it cannot be pushed in, it means that the dimension exceeds the upper limit, and it is judged to be unqualified. Use the second clamping groove 21 of the second inner surface spacing gauge jaw 2 to clamp on the upper side of the measured plane positioning and mounting block 41 and the lower surface of the measured steering knuckle 5, and the second clamping groove 21 is pushed in by fitting the upper surface of the measured plane positioning and mounting block 41. If it can be completely inserted, it means that the dimension is above the lower limit height, and it is judged to be qualified. If it cannot be pushed in, it means that the dimension is lower than the lower limit, and it is judged to be unqualified. Only when the measurement conditions of both the first clamping groove 11 and the second clamping groove 21 are qualified can the test be judged to be qualified, and the rest of the situations are unqualified.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indicators will also change accordingly.

[0025] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features.
