Detailed implementation manners

[0018] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention fall within the protection scope of the present invention.

[0019] The following combines Figures 1 - 7 to describe the structure and working principle of the present invention.

[0020] Referring to Figure 1 , a surface symmetry detection device provided by the present invention includes a support component 100, a driving component 200 and a positioning component 400. The driving component 200 is arranged on the support component 100. The driving component 200 is provided with at least one distance detection component 300. The driving component 200 is used to drive the distance detection component 300 to move along a preset trajectory. The positioning component 400 is arranged at an interval from the distance detection component 300. The positioning component 400 is used to fix the leaf spring 500 so that the leaf spring 500 is parallel to the preset trajectory.

[0021] Specifically, the distance detection component 300 can be a laser ranging component. The laser ranging component includes a laser emitter, a laser receiver, a timer and a calculation module. Among them, the laser emitter is used to generate and emit laser pulses with a specific wavelength. After the laser pulses are emitted, they are reflected when encountering the leaf spring 500. The laser receiver is responsible for capturing the laser pulses reflected by the leaf spring 500. The timer starts synchronously with the laser emitter and stops timing when the laser receiver receives the reflected pulses. The calculation module uses the recorded time difference and the known value of the speed of light, and determines the distance between the distance detection component 300 and the leaf spring 500 through the formula (distance = speed of light × time / 2).

[0022] When fixing the leaf spring 500, the bent side of the leaf spring 500 needs to be set facing the detection component 300 (as Figure 1 shown). And the center of the leaf spring 500 should coincide with the center of the positioning component 400. With such a setting, the center of the positioning component 400 can be used as a reference point, and both sides of it are symmetrically arranged. Furthermore, by measuring the distances between the parts of the leaf spring 500 on both sides of the reference point and at the same distance from the reference point to the detection component 300, the symmetry of the leaf spring 500 can be measured. When the two distances are the same, it indicates symmetry (within the allowable error range).

[0023] In the present invention, the leaf spring 500 is fixed by the positioning component 400, and the leaf spring 500 is parallel to the preset trajectory of the detection component 300. Furthermore, the position of the leaf spring 500 and its angle relative to the detection component 300 can be accurately controlled, ensuring a high degree of accuracy in the measurement process. In addition, the driving component 200 can drive the distance detection component 300 to move along the preset trajectory, so as to fully cover the surface of the leaf spring 500, ensuring a detailed detection of the entire leaf spring curved surface. Moreover, since the present invention adopts the laser ranging technology, the device can achieve non-contact high-precision measurement, reducing the errors that may be brought by traditional mechanical measurement methods. The present invention not only improves the quality control level of the leaf spring itself, but also indirectly promotes the improvement of the driving stability of the whole vehicle. By accurately measuring the symmetry of the leaf spring curved surface, the stress concentration problem caused by asymmetry can be effectively reduced, the service life of the leaf spring can be extended, and the overall performance of the vehicle suspension system can be improved.

[0024] Referring to Figure 1 , in some embodiments of the present invention, the driving component 200 includes a guiding component 210 and a driving component 220. Among them, the guiding component 210 is arranged on the supporting component 100, and the guiding component 210 is used to guide the distance detection component 300 so that the distance detection component 300 moves along the preset trajectory; the driving component 220 is arranged at an interval from the guiding component 210, and the guiding component 210 is used to drive the distance detection component 300 to move.

[0025] The driving component 200 includes a guiding component 210 and a driving component 220. Among them, the guiding component 210 is arranged on the supporting component 100 and is used to guide the distance detection component 300 to ensure that it moves along the preset trajectory; the driving component 220 is arranged at an interval from the guiding component 210, and the driving component 220 is used to drive the distance detection component 300 to move. This design ensures that the distance detection component 300 can move along the predetermined path under precise control, so as to achieve high-precision measurement of the curved surface of the leaf spring 500. In the present invention, through the coordinated work of the guiding component 210 and the driving component 220, the distance detection component 300 can move smoothly along the preset trajectory, realizing a comprehensive detection of the surface of the leaf spring 500.

[0026] Specifically, in the above structure, the guiding component 210 serves to provide a clear and stable path for the distance detection component 300, enabling it to move along a preset trajectory. The guiding component 210 ensures that the distance detection component 300 maintains the correct direction and position throughout the measurement process through mechanical constraints or guide rails, etc., avoiding measurement errors caused by path deviations. This not only improves the consistency and accuracy of the measurement results but also enables the system to operate stably under different conditions.

[0027] The driving component 220 is responsible for providing power to enable the distance detection component 300 to move smoothly and continuously along the path set by the guiding component 210. The driving component 220 can use a motor, a lead screw, or other transmission devices to achieve this function. The design of the driving component 220 ensures that the distance detection component 300 can move precisely in a linear or curved motion along the predetermined trajectory under the guidance of the guiding component 210, thereby covering all key areas of the leaf spring 500. This combination not only improves the measurement efficiency but also ensures the reliability and repeatability of each measurement.

[0028] Refer to Figure 1 , in some embodiments of the present invention, the guiding component 210 includes at least two support frames 211, a cross beam 212, and a guiding groove 213. When the support frames 211 are spaced apart and arranged in the middle of the support assembly 100; the cross beam 212 is arranged at the top of the support frames 211; the guiding groove 213 is arranged on the cross beam 212, and the distance detection component 300 is in sliding fit with the guiding groove 213.

[0029] It should be noted that the number of support frames 211 needs to be set according to the actual situation. In some specific embodiments, it can be specifically set to two. The bottom ends of the support frames 211 can be connected to the support assembly 100 by welding or bolt connection. One end of the cross beam 212 is welded to the top of one of the support frames 211, and the other end of the cross beam 212 is welded to the top of the other support frame 211. The guiding groove 213 is arranged on one side surface of the cross beam 212, specifically, it can be the upper surface. At the same time, in order to improve the stability of the support frames 211, a plurality of side support rods can also be arranged between the bottom of the support frames 211 and the support assembly 100.

[0030] In the above structure, the support frames 211 provide a stable foundation. By being spaced apart and arranged in the middle of the support assembly 100, the stability of the entire guiding system is ensured. The design of the support frames 211 enables the cross beam 212 to maintain a horizontal state under different working conditions, avoiding distance detection errors caused by unstable support. The cross beam 212 is arranged at the top of the support frames 211, providing an installation platform for the guiding groove 213 and ensuring its fixed position.

[0031] The guiding groove 213 is provided on the cross beam 212 and is used to guide the distance detection component 300 to move along a preset trajectory. The distance detection component 300 is in sliding fit with the guiding groove 213 to ensure that it always maintains the correct direction and position during the movement. The design of the guiding groove 213 not only defines the movement path of the distance detection component 300, but also reduces the influence of external factors on its movement, improving the stability and accuracy during the measurement process.

[0032] Referring to Figures 1 to 3 , in some embodiments of the present invention, the driving component 220 includes a motor 221, at least one screw rod 222 and a sliding member 224. Among them, the motor 221 is arranged at one end of the top of the support component 100; the screw rod 222 is rotatably arranged at the top end of the support component 100, and one end is connected to the output shaft of the motor 221; the sliding member 224 is arranged corresponding to the distance detection component 300 one by one. The distance detection component 300 is arranged on the sliding member 224. The distance detection component 300 is in sliding fit with the guiding groove 213 through the sliding member 224. The screw rod 222 passes through the sliding member 224 and is threadedly connected to the sliding member 224.

[0033] Specifically, both ends of the screw rod 222 are rotatably arranged at the top end of the support component 100 through fixing seats 223. The fixing seats 223 are detachably arranged at the top end of the support component 100. A plurality of bearings are arranged on the fixing seats 223. The screw rod 222 passes through the bearings and is limited to the inner ring of the bearings. One screw rod 222 can be provided, or two screw rods 222 can be provided. In order to improve the sliding member 224, two of them can be arranged side by side (as Figure 3 shown). It should be noted that the length of the screw rod 222 needs to be greater than the length of the leaf spring 500, and the stroke of the sliding member 224 needs to be able to complete the measurement of the entire leaf spring 500. In some embodiments, the guiding component 210 can also play a role in supporting the screw rod 222. A support member 214 can be fixedly arranged in the middle of the cross beam 212. A bearing 215 is arranged in the middle of the support member 214. The number of bearings 215 is arranged corresponding to the number of screw rods 222 one by one. Such an arrangement can provide a certain support for the middle part of the screw rod 222 and increase the stability of the screw rod 222.

[0034] In the above structure, the motor 221 provides a power source. It is arranged at one end of the top of the support component 100 and directly drives the screw rod 222 to rotate through the output shaft. This design ensures that the motor 221 can stably transmit power to the screw rod 222, thereby driving the sliding member 224 to move along the axis direction of the screw rod 222. Since the screw rod 222 and the sliding member 224 are threadedly connected, when the motor 221 drives the screw rod 222 to rotate, the sliding member 224 will perform a linear motion along the screw rod 222.

[0035] The sliding member 224 and the distance detection assembly 300 are arranged in a one-to-one correspondence. The distance detection assembly 300 is installed on the sliding member 224, enabling the distance detection assembly 300 to move along a preset trajectory together with the sliding member 224. The sliding member 224 is in sliding fit with the guiding groove 213, ensuring that the sliding member 224 and the distance detection assembly 300 thereon always maintain the correct direction and position during the movement, and avoiding measurement errors caused by deviation from the track.

[0036] With this structure, the motor 221 drives the screw 222 to rotate, thereby enabling the sliding member 224 to perform precise linear motion along the screw 222, ensuring that the distance detection assembly 300 can move smoothly and accurately along the predetermined path. This design not only improves the stability and accuracy during the measurement process but also realizes automated operation, reducing the need for manual intervention.

[0037] Meanwhile, the guiding groove 213 provides further guiding, ensuring that the sliding member 224 and the distance detection assembly 300 thereon do not deviate or jitter during the movement. Combining the function of the guiding groove 213, the entire system can complete a comprehensive inspection of the curved surface of the leaf spring 500 under high-precision conditions.

[0038] Refer to Figure 4 In some embodiments of the present invention, a limiting portion 2242 is provided at the bottom of the sliding member 224. A plurality of rolling bodies 2243 are provided on the outer periphery of the limiting portion 2242, and the rolling bodies 2243 are in sliding fit with the guiding groove 213. The sliding member 224 is provided with a threaded hole 2241, and the screw 222 passes through the threaded hole 2241 and is threadedly connected. It should be noted that the shape of the limiting portion 2242 is adapted to the shape of the guiding groove 213, and such a setting can improve the stability of the movement of the sliding member 224.

[0039] In the above structure, the limiting portion 2242 is provided at the bottom of the sliding member 224, providing additional mechanical constraints to ensure that the sliding member 224 does not deviate or tilt when moving along the predetermined trajectory driven by the screw 222. The design of the limiting portion 2242 enables the sliding member 224 to be accurately positioned within the guiding groove 213, and the movement accuracy and stability of the sliding member 224 are further enhanced by the plurality of rolling bodies 2243 provided on its outer periphery.

[0040] The rolling elements 2243 are in sliding fit with the guide groove 213, reducing the frictional force between the sliding member 224 and the guide groove 213, thereby reducing the movement resistance and improving the operation efficiency and stability of the system. The rolling elements 2243 can be ball bearings or other rolling elements with a low coefficient of friction, and they are evenly distributed on the outer periphery of the limiting portion 2242 to ensure that the sliding member 224 maintains a smooth and straight movement trajectory during movement. This design not only reduces the error caused by friction but also extends the service life of the guide groove 213 and the rolling elements 2243.

[0041] Through the synergistic effect of the limiting portion 2242 and the rolling elements 2243, when the motor 221 drives the screw 222 to rotate, the sliding member 224 can perform precise linear motion along the guide groove 213. This design ensures that the distance detection assembly 300 can move stably and accurately along the preset trajectory.

[0042] Refer to Figure 5 , in some embodiments of the present invention, the support assembly 100 includes at least two support arms 110 and a bottom plate 120. Among them, the two support arms 110 are arranged at intervals; the bottom plate 120 is disposed between the two support arms 110, and the positioning assembly 400 is located in the middle of the bottom plate 120. Specifically, there are two support arms 110, and the bottom plate 120 is welded between the bottom ends of the two support arms 110 to form a U-shaped structure.

[0043] In the above structure, the support arms 110 provide stable vertical support to ensure that the entire detection device remains stable during use. The two support arms 110 are arranged at intervals, which not only provides sufficient installation space for the drive assembly 200 and the distance detection assembly 300 but also ensures the rigidity and strength of the overall structure. The design of the support arms 110 enables them to withstand forces from different directions and avoid measurement errors caused by external vibration or uneven load.

[0044] The bottom plate 120 is disposed between the two support arms 110 and is fixed to the bottom ends of the support arms 110 by welding to form a U-shaped structure. This design enhances the overall stability of the support assembly 100 and ensures its rigidity in both horizontal and vertical directions under various working conditions. The bottom plate 120 serves as the basic platform of the entire device, providing space for installing the positioning assembly 400 and ensuring the position accuracy of the positioning assembly 400. The positioning assembly 400 is located in the middle of the bottom plate 120 to ensure that the leaf spring 500 can be accurately fixed during the detection process, thereby improving the consistency and accuracy of the measurement results.

[0045] Through this structure, the support assembly 100 not only provides a stable support base for the driving assembly 200, the distance detection assembly 300 and the positioning assembly 400, but also ensures that the relative position relationship between the various components is maintained. The combination of the support arm 110 and the base plate 120 forms a solid overall frame, so that the entire detection device can operate under high precision conditions.

[0046] The support arm 110 needs to have sufficient rigidity and strength to ensure that the entire detection device remains stable during operation. Therefore, the support arm 110 can be made of high-strength alloy steel. High-strength alloy steel not only provides the necessary mechanical strength, but also can maintain the stability of shape and size during long-term use, avoiding measurement errors caused by material fatigue or deformation. In addition, high-strength alloy steel has good processing properties and can be accurately formed through processes such as welding and cutting to ensure that the connection between the support arm 110 and the base plate 120 is firm and reliable.

[0047] The bottom plate 120 can also be made of high-strength alloy steel to provide a stable installation platform to ensure that the positioning assembly 400 can accurately position the leaf spring 500. The high rigidity and low deformation characteristics of high-strength alloy steel enable the bottom plate 120 to maintain horizontal and vertical stability when subjected to forces in different directions, thereby improving the measurement accuracy of the overall device.

[0048] The choice of material not only affects the mechanical properties of the support arm 110 and the base plate 120, but also their corrosion resistance and service life. High-strength alloy steel generally has good corrosion resistance, but in order to further enhance its protection ability, anti-corrosion treatment can also be performed on the surface, such as galvanizing or coating with anti-rust paint. These treatment methods can effectively prevent the material from oxidizing in a humid or corrosive environment and extend the service life of the support assembly 100.

[0049] Reference Figure 1 and Figure 3 In some embodiments of the present invention, two distance detection components 300 are provided, and the two distance detection components 300 move away from or approach each other with the positioning component 400 as the center.

[0050] In this embodiment, the screw 222 is a double-helical screw, the center of the double-helical screw is aligned with the center of the positioning assembly 400, and the thread rotation directions on both sides of the center of the double-helical screw are just opposite. The two distance detection assemblies 300 are symmetrically arranged on the double-helical screw. In this way, when the double-helical screw is rotated, the two distance detection assemblies 300 can move away from and toward each other. In addition, the symmetrical parts of the leaf spring 500 can be measured at the same time, and a better comparison can be made, and the symmetry of the leaf spring 500 can be better judged.

[0051] ReferenceFigure 6 and Figure 7 In some embodiments of the present invention, the positioning component 400 includes a mounting platform 410, at least two limiting side plates 420, and a positioning portion 430. Among them, the mounting platform 410 is provided on the bottom plate 120; the limiting side plates 420 are provided on both sides of the top of the mounting platform 410, and the limiting side plates 420 are used to limit the leaf spring 500; the positioning portion 430 is provided at the center of the top end of the mounting platform 410, and the positioning portion 430 is used to position the leaf spring 500.

[0052] Among them, the mounting platform 410 includes a mounting plate 412. Fixed wings 411 are provided on the left and right sides of the mounting plate 412. The fixed wings 411 are detachably connected to the bottom plate 120. Limiting grooves 413 are provided on both the front and rear sides of the mounting plate 412, and the limiting grooves 413 are used to limit the limiting side plates 420. The limiting side plates 420 include a side plate body 421. A clamping seat 422 is provided at the bottom of the side plate body 421, and the clamping seats 422 are respectively and correspondingly limited in the limiting grooves 413.

[0053] In the above structure, the mounting platform 410 serves as the basic platform for the entire positioning component 400, providing a stable support foundation. The fixed wings 411 are combined with the bottom plate 120 through a detachable connection method, which not only simplifies the installation process but also facilitates subsequent adjustment and maintenance. The design of the limiting grooves 413 ensures that the limiting side plates 420 can be accurately aligned and fixed in a predetermined position, avoiding measurement errors caused by position deviation.

[0054] The limiting side plates 420 are tightly connected to the mounting platform 410 through the cooperation of the clamping seats 422 and the limiting grooves 413. The side plate body 421 is provided on both sides of the top of the mounting platform 410 and is used to limit the leaf spring 500. This design ensures that the leaf spring 500 can be accurately fixed during the detection process and prevents it from shifting or tilting during the measurement process, thereby improving the consistency and accuracy of the measurement results.

[0055] The positioning portion 430 is provided at the center of the top end of the mounting platform 410 and is used to further accurately position the leaf spring 500. By aligning the center of the leaf spring 500 with the positioning portion 430, it can be ensured that the leaf spring 500 maintains the correct posture and position during the detection process. This design not only improves the positioning accuracy but also provides a reliable reference point for subsequent distance detection, ensuring the accuracy of the measurement data.
