[0031] First embodiment

[0032] See also Figure 1 to Figure 6 The present invention provides an automobile steering wheel skeleton inspection device, comprising a base 101 and a support frame 102, wherein the support frame 102 is fixedly connected to the base 101 and is located on the top of the base 101, and further comprising a placement component 103 and a detection component 104, wherein the placement component 103 comprises a rotating motor 105, a support platform 106, and a mounting column 107, wherein the rotating motor 105 is fixed to the base 101, the support platform 106 is connected to the output end of the rotating motor 105, and the mounting column 107 is arranged on the support platform 106, and the detection component 104 comprises an adjustment seat 108, a lateral movement unit 109 and a point cloud laser scanning unit 110, wherein the adjustment seat 108 is arranged on the support frame 102, the lateral movement unit 109 is slidably arranged on the adjustment seat 108, and the point cloud laser scanning unit 110 is arranged on the lateral movement unit 109, and is used to perform laser scanning on the steering wheel skeleton.

[0033] In this embodiment, the base 101 serves as the basic platform of the entire device and provides stable support; the support frame 102 is fixedly connected to the base 101 and is located on the top of the base 101, providing the necessary installation space and support force for other components. The rotating motor 105 is firmly mounted on the base 101, and is connected to the support platform 106 through its output end, so as to drive the support platform 106 to rotate. This function allows the steering wheel skeleton to be displayed 360 degrees in all directions during the detection process, ensuring a dead-angle scan. The support platform 106 is directly connected to the output shaft of the rotating motor 105, and not only bears the weight of the mounting column 107 and the steering wheel skeleton thereon, but also rotates synchronously with the drive of the motor. The design of the support platform 106 takes into account strength and stability to ensure that good balance can be maintained even at high-speed rotation.

[0034] The mounting column 107 is erected on the support platform 106 and is specifically used to fix the steering wheel frame. Its design can be adjusted according to different models of steering wheel frames to ensure that each frame can be accurately and firmly placed on it, so as not to affect the subsequent detection process. The detection component 104 is the core part of realizing automatic detection. The adjustment seat 108 is installed on the support frame 102, providing an adjustable position reference for the lateral movement unit 109. It can adjust the height manually or electrically, so that the point cloud laser scanning unit 110 can adapt to steering wheel frames of different sizes and shapes to achieve the best scanning position. The lateral movement unit 109 can move freely in the horizontal direction. This feature allows the point cloud laser scanning unit 110 to scan the steering wheel frame in a wider range, covering all areas that need to be inspected.

[0035] The point cloud laser scanning unit 110 is arranged on the lateral moving unit 109. Using advanced laser technology, the point cloud laser scanning unit 110 can quickly generate a high-resolution three-dimensional image of the steering wheel skeleton. By comparing with the preset standard model, it can accurately identify any slight deviation or defect, such as uneven material thickness, surface flaws, etc. In addition, the unit is also equipped with an efficient processing algorithm, which can complete the analysis of a large amount of data in a short time, greatly improving the detection speed and accuracy.

[0036] In summary, this automobile steering wheel frame inspection device combines the advantages of mechanical movement and optical measurement to achieve efficient and accurate inspection of the steering wheel frame, which is of great significance for improving product quality.

[0037] The placement assembly 103 further includes a flexible pad 111 , and the flexible pad 111 is fixed to the support platform 106 .

[0038] In order to protect the steering wheel frame from damage during the detection process and provide a better positioning effect, a layer of flexible pad 111 is fixed on the support platform 106. The flexible pad 111 is made of high-quality elastic material, which is soft enough to absorb slight collisions or frictions, and has good wear resistance and anti-aging properties, ensuring stability and durability under long-term use.

[0039] The mounting column 107 includes a mounting column body 112, a plurality of blocks 113, a pushing cylinder 114, a push block 115 and a return spring 116. The mounting column body 112 is fixed to the center of the support platform 106. The plurality of blocks 113 are slidably arranged in the grooves on the mounting column body. The push block 115 is slidably arranged in the mounting column body 112. The output end of the pushing cylinder 114 is connected to the push block 115. The wedge-shaped surface of the push block 115 moves upward to push out the plurality of blocks 113. The return spring 116 is arranged between the push block 115 and the pushing cylinder 114.

[0040] The mounting column body 112 as the basic structure of the entire mounting column 107 is firmly fixed to the center of the support platform 106, providing a solid mounting platform for other components.

[0041] Several blocks 113 are evenly distributed around the mounting column body 112, and these blocks 113 can slide left and right in the slots on the mounting column body 112. When the steering wheel frame needs to be fixed, the blocks 113 can expand outward from the inside to tightly clamp the inner wall of the steering wheel frame to achieve a stable fixation; in the released state, the blocks 113 will automatically shrink back into the mounting column 107, making it easy to remove the steering wheel frame that has been tested.

[0042] A push cylinder 114 is arranged in the mounting column body 112, and its output end is connected to a wedge-shaped push block 115. By controlling the action of the push cylinder 114, the push block 115 can be moved axially along the mounting column body 112. When the push block 115 moves upward, its wedge-shaped surface will push out each block 113, thereby expanding the distance between the blocks 113, achieving the effect of fixing the steering wheel frame; on the contrary, when the push block 115 moves downward, the block 113 will retract under the action of the return spring 116, which is convenient for loading and unloading operations.

[0043] The return spring 116 is located between the push block 115 and the push cylinder 114, and is used to ensure that the push block 115 remains in the initial position when there is no external force. At the same time, after the push cylinder 114 drives the push block 115 to move upward, the return spring 116 can also store energy so as to quickly restore the original state when needed, thereby improving work efficiency.

[0044] The placement component 103 also includes a limit frame 117, a limit cylinder 118 and a second spring 119. The limit frame 117 is slidably arranged on one side of the support platform 106, the output end of the limit cylinder 118 is connected to the limit frame 117, and the second spring 119 is arranged between the limit frame 117 and the limit cylinder 118.

[0045] The limiting frame 117 is slidably disposed on one side of the supporting platform 106, and its extension length can be adjusted according to different types of steering wheel frames to ensure that the steering wheel can be accurately positioned every time to better pre-fix the steering wheel.

[0046] The output end of the limit cylinder 118 is connected to the limit frame 117, which is responsible for driving the limit frame 117 to perform telescopic action. By accurately controlling the working state of the limit cylinder 118, the position of the limit frame 117 can be flexibly adjusted to meet the detection requirements of steering wheel skeletons of various sizes and shapes.

[0047] The second spring 119 is placed between the limit frame 117 and the limit cylinder 118, and mainly plays a buffering role. It can provide a certain elasticity and stability when the limit frame 117 is impacted or vibrated, avoiding the problem of inaccurate positioning caused by sudden external force. At the same time, the second spring 119 also helps the limit frame 117 to quickly return to the initial position after completing a test, ready to welcome the arrival of the next piece to be tested.

[0048] The adjustment seat 108 includes a seat body 120 and a locking screw 121 . The seat body 120 is slidably disposed on the support frame 102 . The locking screw 121 is threadedly connected to the seat body 120 and passes through the seat body 120 .

[0049] The seat body 120 is the core structure of the adjustment seat 108. The seat body 120 is slidably arranged on the support frame 102 and can move freely in the vertical direction. Its design takes into account the requirements of strength and lightness, and is made of high-strength aluminum alloy material, which not only ensures sufficient mechanical strength, but also reduces the overall weight, making the movement smoother.

[0050] The seat body 120 is connected to the support frame 102 by a set of well-designed locking screws 121. These screws not only form a threaded connection with the seat body 120, but also pass through the seat body 120. When the position of the seat body 120 needs to be fixed, a tight fit can be achieved by tightening the screws to prevent any unnecessary displacement.

[0051] The adjustment seat 108 also includes a laser emitting unit 122, and a light receiving unit 123 is arranged on the mounting column body 112. The judgment unit is connected to the light receiving unit 123. The laser emitting unit 122 emits a positioning light and obtains a position signal through the light receiving unit 123. The judgment unit calculates the adjustment parameters of the seat body 120 according to the position signal.

[0052] The laser emitting unit 122 is integrated in the adjustment seat 108 and is used to emit a high-precision laser beam. The laser emitting unit 122 uses a low-power but highly stable laser source, which can produce a clear, visible and stable laser line or point within a short distance, thereby providing a reliable reference for subsequent positioning operations.

[0053] A light receiving unit 123 is provided at a corresponding position on the mounting column body 112, which can capture the laser signal emitted and reflected by the laser emitting unit 122. The light receiving unit 123 has a built-in highly sensitive photoelectric sensor, which can quickly respond to and record the received laser information, and can maintain a high signal-to-noise ratio even under weak light conditions.

[0054] The judgment unit is an intelligent control system connected to the light receiving unit 123 and is responsible for processing the received position signal. Through complex algorithm analysis, the judgment unit can calculate the specific position of the seat body 120 relative to the mounting column 107 based on the data provided by the light receiving unit 123, and adjust the height and other parameters of the seat body 120 accordingly to ensure that the point cloud laser scanning unit 110 can be in the best working state. In addition, the judgment unit can also monitor and feedback the position change in real time, making the entire detection process more automated and intelligent.

[0055] In actual operation, the steering wheel frame to be tested is first placed on the mounting column 107, and the laser emitting unit 122 will emit positioning light to the mounting column 107. As the seat body 120 slides left and right along the support frame 102, the light receiving unit 123 continuously receives the reflected laser signal and transmits this information to the judgment unit. The judgment unit compares and analyzes the preset standard model and the currently received position signal. Once a deviation is found, it will immediately send a command to the driving mechanism (such as an electric motor or a cylinder) of the adjustment seat 108 to prompt the seat body 120 to make fine adjustments until the ideal position is reached.

[0056] The lateral moving unit 109 includes a moving screw 125, a first motor 126 and a mounting block 127. The first motor 126 is fixed to the base body 120, the moving screw 125 is connected to the output end of the first motor 126, the mounting block 127 is threadedly connected to the moving screw 125, and is slidably connected to the support frame 102.

[0057] The moving screw 125 is the core transmission component of the lateral moving unit 109. The moving screw 125 is connected to the output end of the first motor 126, and drives the mounting block 127 to move precisely along the predetermined track by converting the rotational motion into the linear motion. In order to ensure the smoothness and accuracy of the movement, the moving screw 125 adopts the precision ball screw technology, which has high transmission efficiency and low friction resistance.

[0058] The first motor 126 is fixed to the seat body 120 of the adjustment seat 108 to provide power for the moving screw 125. It uses a high-performance stepper motor or servo motor, which has the characteristics of precise positioning and rapid response, and can quickly adjust the position according to the instructions issued by the control system. In addition, the motor is also equipped with an encoder feedback system, which can monitor its own speed and angle in real time to further improve the accuracy of position control.

[0059] The mounting block 127 is threadedly connected to the moving screw 125 and is slidably disposed in the guide rail on the support frame 102. When the moving screw 125 rotates, the mounting block 127 will perform linear motion along the guide rail, driving the point cloud laser scanning unit 110 to move synchronously. The design of the mounting block 127 takes strength and flexibility into consideration, ensuring sufficient rigidity to support the scanning unit while allowing it to slide freely in the guide rail, thereby achieving efficient and stable lateral movement.

[0060] The detection component 104 further includes a rim detection unit 128 and a skeleton detection unit 129. The rim detection unit 128 is used to detect the edge of the steering wheel skeleton; the skeleton detection unit 129 is used to detect the middle bracket of the steering wheel skeleton.

[0061] The rim detection unit 128 is mainly used to detect the edge of the steering wheel skeleton to facilitate adjustment of the position of the point cloud laser scanning unit 110. The skeleton detection unit 129 focuses on the detection of the middle bracket part of the steering wheel skeleton, so that when the middle bracket is rotated to the position, the point cloud laser scanning unit 110 can be moved to scan the middle bracket.

[0062] The rim detection unit 128 includes a moving block 130, a second spring 119, a displacement detector 132 and a contact wheel 133. The moving block 130 is slidably arranged on the base 101, the second spring 119 is arranged on one side of the moving block 130, the displacement detector 132 is arranged on the moving block 130, and the contact wheel 133 is rotatably arranged on the moving block 130 for contacting the steering wheel frame.

[0063] The moving block 130 is slidably mounted on the base 101 and can move freely within a certain range. Its function is to adjust the position of the contact wheel 133 during the detection process so that it can closely follow the edge contour of the steering wheel frame. A guide mechanism is provided inside the moving block 130 to ensure that its moving track is straight and stable and will not affect the detection results.

[0064] The second spring 119 is disposed on one side of the moving block 130 to provide appropriate pre-pressure so that the contact wheel 133 can always maintain good contact with the steering wheel frame.

[0065] The displacement detector 132 is integrated on the moving block 130 and is used to monitor the displacement change of the contact wheel 133 relative to the initial position in real time. The detector uses a high-resolution photoelectric sensor or an inductive displacement sensor, which can capture tiny position changes and provide an accurate basis for subsequent data analysis.

[0066] The contact wheel 133 is rotatably arranged on the moving block 130 and directly contacts the steering wheel frame. The surface of the contact wheel 133 is specially treated to be smooth and have a certain friction coefficient, so that it can smoothly follow the edge shape of the frame during rolling while avoiding scratches or wear. The diameter and material selection of the contact wheel 133 are carefully considered to adapt to different models of steering wheel frames.

[0067] Second embodiment

[0068] See also Figure 7 The present invention also provides a method for inspecting a car steering wheel skeleton, comprising:

[0069] S201: placing the car steering wheel frame on the mounting column 107 of the support platform 106 for fixing;

[0070] The operator carefully places the steering wheel frame to be inspected on the mounting column 107 on the support platform 106. The mounting column 107 is designed with a plurality of adjustable blocks 113. Under the action of the push cylinder 114, these blocks 113 can expand from the inside to the outside, tightly clamping the inner wall of the steering wheel frame to achieve a stable fixation. The presence of the flexible pad 111 not only protects the surface of the steering wheel frame from damage, but also provides an anti-slip function to ensure that no deviation occurs during the subsequent rotation process.

[0071] S202 starts the rotating motor 105 to drive the rotating platform to rotate, and at the same time drives the steering wheel frame to rotate;

[0072] Once the steering wheel frame is securely fixed, the control system will issue a command to start the rotation motor 105. The motor drives the support platform 106 and the steering wheel frame thereon to rotate 360 ​​degrees in all directions to prepare for the next scanning process. In this step, the rotation speed can be adjusted as needed to ensure stability and accuracy during scanning.

[0073] S203 the point cloud laser scanning unit 110 scans the steering wheel skeleton to obtain first scanning data;

[0074] As the steering wheel skeleton slowly rotates, the point cloud laser scanning unit 110 located on the lateral moving unit 109 starts to work. It uses a high-precision laser beam to fully scan the steering wheel skeleton and quickly generate detailed three-dimensional image data. The first scan data obtained at this stage contains all the geometric features of the outer edge of the steering wheel skeleton, such as edge contours, surface textures, etc., laying the foundation for subsequent analysis.

[0075] S204: When the middle bracket of the steering wheel frame is detected, the rotating platform stops rotating, and the lateral moving unit 109 is started to drive the point cloud laser scanning unit 110 to scan the middle bracket to obtain second scanning data;

[0076] During the scanning process, the judgment unit monitors the position signal in real time. Once the position of the intermediate bracket is identified, the control system immediately commands the rotating table to stop rotating and starts the lateral movement unit 109. At this time, the point cloud laser scanning unit 110 moves horizontally to the optimal scanning position and performs a detailed scan specifically for the intermediate bracket part. The second scanning data obtained focuses on the structural details of the intermediate bracket, such as thickness changes, integrity of the connection parts, etc., which are crucial for evaluating its strength and durability.

[0077] S205: the lateral moving unit 109 is reset, and the rotating platform continues to drive the steering wheel skeleton to rotate and scan, and finally obtains complete vehicle steering wheel skeleton data;

[0078] After completing the special scan of the middle bracket, the lateral moving unit 109 returns to the initial position, and the rotating table starts again to continue to drive the steering wheel skeleton to rotate. During this period, the point cloud laser scanning unit 110 continues to work until all areas of the entire skeleton are fully scanned. Finally, all the scanning data are integrated to form a complete and detailed three-dimensional model of the automobile steering wheel skeleton, covering the shape and size information of each part.

[0079] S206 calculates the steering wheel deformation based on the vehicle steering wheel skeleton data.

[0080] The final step is to conduct an in-depth analysis of the collected data. By comparing the actual measurement results with the preset standard template, the deformation of each part of the steering wheel frame can be accurately calculated. This includes but is not limited to bending, twisting, and local deformation. If any deviation beyond the allowable range is found, the system will automatically mark and record it so that corrective measures can be taken later or unqualified products can be directly eliminated.

[0081] In summary, this automobile steering wheel frame inspection method not only improves the inspection efficiency, but also significantly enhances the accuracy and reliability of the inspection results, providing solid technical support for ensuring the safety and performance of automobile parts.

[0082] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
