[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example

[0021] Reference Figure 1 and 4 The first embodiment of this utility model provides a detection component 1 including an operating table 101 and a control panel 102. The upper end of the operating table 101 is fixedly connected to the lower end of the control panel 102. A tensioning mechanism 2 is provided inside the operating table 101. A fixing mechanism 3 is provided at the upper end of the tensioning mechanism 2. The tensioning mechanism 2 is used to detect the elasticity of the spring, and the fixing mechanism 3 is used to fix the two ends of the spring.

[0022] Specifically, the detection component 1, by setting the fixing mechanism 3 and the tensioning mechanism 2 on the operating table 101 and linking them with the control panel 102, effectively solves the problems of unstable clamping, inaccurate motion control, and low operating efficiency during spring detection. The fixing mechanism 3 achieves synchronous clamping of both ends of the spring, ensuring accurate positioning. The tensioning mechanism 2 provides stable reciprocating tension force through the cam 202 linkage transmission, realistically simulating the working force state. The overall structure, together with the control panel 102, achieves automated operation, improving the repeatability, accuracy, and efficiency of detection, and reducing human error.

[0023] Furthermore, when it is necessary to perform quality inspection on the processed spring, the spring to be tested must first be placed stably on the designated position of the operating table 101 to ensure that its axis is aligned with the movement direction of the testing component 1. Then, the two ends of the spring are fixed by the fixing mechanism 3, and the elasticity of the spring is tested by the tensioning mechanism 2. Example

[0024] The second embodiment of this utility model provides a tensioning mechanism 2 including a servo motor 201, a cam 202, a connecting rod 203, a fixed seat 204, and an auxiliary wheel 205. The output end of the servo motor 201 is fixedly connected to the inner wall of the cam 202. The inner wall of the cam 202 is rotatably connected to the surface of the connecting rod 203 via a rotating shaft. The surface of the connecting rod 203 is rotatably connected to the inner wall of the fixed seat 204 via a rotating shaft. The outer side of the fixed seat 204 is rotatably connected to the inner wall of the auxiliary wheel 205 via a rotating shaft. The surface of the servo motor 201 is fixedly connected to the lower end of the operating table 101. The surface of the cam 202 is rotatably connected to the inner wall of the operating table 101 via a sliding groove. The surface of the fixed seat 204 is slidably connected to the inner wall of the operating table 101 via a sliding groove. The surface of the auxiliary wheel 205 is slidably connected to the inner wall of the operating table 101.

[0025] Specifically, the stretching mechanism 2 drives the cam 202 and the linkage transmission structure through the servo motor 201, which effectively solves the problems of unstable motion and inaccurate stroke control in traditional spring detection. The non-circular contour of the cam 202 transforms the uniform rotation into the controllable reciprocating linear motion of the fixed seat 204. With the hinge transmission of the connecting rod 203, the periodic stretching of the spring is achieved. The fixed seat 204 cooperates with the slide groove of the operating table 101 and is supported by the rolling of the auxiliary wheel 205 to reduce frictional resistance, prevent motion jamming and uneven load, ensure the smooth stretching process, and improve the repeatability and data reliability of the detection.

[0026] Furthermore, after the spring ends are fixed, the tensile performance test can be initiated. The servo motor 201 is started via the control panel 102, and its output drives the cam 202 to rotate. The cam 202, as a key motion conversion element, has non-circular geometric features with continuously changing contours. During uniform rotation, it converts rotational motion into the periodic reciprocating motion required by the follower. The contour change of the cam 202 contacts and pushes one end of the connecting rod 203, while the other end of the connecting rod 203 is hinged to the fixed seat 204 via a rotating shaft. The fixed seat 204 is integrally embedded in the guide groove on the inner wall of the operating table 101, allowing it to slide linearly within it. As the cam 202 rotates... 2. Continuous rotation of the connecting rod 203 converts the radial displacement change of the cam 202 into the reciprocating linear motion of the fixed seat 204, thereby applying a tensile load to the fixed spring and simulating the force situation under actual working conditions. To ensure the smoothness of the tensile testing process and the accuracy of the motion trajectory, auxiliary guide structures are set at both ends of the fixed seat 204. Specifically, the fixed seat 204 is equipped with an auxiliary wheel 205 through a rotating shaft. The auxiliary wheel 205 contacts the guide rail on the inner wall of the operating table 101 and rolls along it, effectively reducing the frictional resistance of the fixed seat 204 in the reciprocating motion, avoiding motion distortion caused by off-center loading or jamming, and improving the reliability and repeatability of the test data. Example

[0027] The third embodiment of this utility model provides a fixing mechanism 3 including a protective cover 301, a fixing motor 302, a driving gear 303, a driven gear 304, an adjusting screw 305, a transmission block 306, a fixing block 307, and a guide plate 308. The surface of the protective cover 301 is fixedly connected to the surface of the fixing motor 302. The output end of the fixing motor 302 is fixedly connected to the inner wall of the driving gear 303. The tooth surface of the driving gear 303 meshes with the tooth surface of the driven gear 304. The inner wall of the driven gear 304 is fixedly connected to the upper end of the adjusting screw 305. The adjustment screw 305 is threadedly connected to the inner wall of the transmission block 306. The surface of the transmission block 306 is fixedly connected to the surface of the fixed block 307. The inner wall of the fixed block 307 is slidably connected to the surface of the guide plate 308. The lower end of the protective cover 301 is fixedly connected to the upper end of the guide plate 308. The driving gear 303 and the driven gear 304 are both located inside the protective cover 301. The lower end of the guide plate 308 is fixedly connected to the upper end of the fixed seat 204. The two ends of the adjustment screw 305 are rotatably connected to the inner walls of the protective cover 301 and the fixed seat 204, respectively.

[0028] Specifically, the fixing mechanism 3 effectively solves the problem of spring displacement or slippage caused by unstable clamping during the testing process through gear transmission and screw transmission. The fixed motor 302 drives the gear set to rotate the adjusting screw 305, causing the transmission block 306 to move axially, realizing the synchronous clamping of the two ends of the spring by the fixing block 307, ensuring uniform clamping force and accurate positioning. The cooperation structure between the guide plate 308 and the protective cover 301 improves the guidance and safety of the moving parts, enhances the stability and reliability of the overall device, and provides a precise initial positioning basis for subsequent tensile testing.

[0029] Furthermore, to ensure the stability of the spring during the testing process, its two ends need to be reliably fixed. The fixed motor 302 is started by operating the control panel 102. The motor output drives the driving gear 303 to rotate. The driving gear 303 meshes with the driven gear 304, thereby transmitting power to the adjusting screw 305, which is coaxially connected to the driven gear 304. The surface of the adjusting screw 305 is provided with a matching threaded transmission block 306. When the screw rotates, the transmission block 306 moves linearly along the axial direction under the action of the thread. Since the transmission block 306 is connected to the fixed block 307, it can drive the fixed block 307 to move synchronously, thereby clamping and positioning the two ends of the spring. After the fixing is completed, the next testing stage begins.

[0030] When quality inspection of the processed spring is required, the spring to be tested must first be placed stably in the designated position on the operating table 101, ensuring that its axis is aligned with the movement direction of the inspection component 1. To ensure the stability of the spring during the inspection process, both ends of the spring must be reliably fixed. The fixed motor 302 is started through the operating control panel 102. The motor output drives the drive gear 303 to rotate. The drive gear 303 meshes with the driven gear 304, thereby transmitting power to the adjusting screw 305, which is coaxially connected to the driven gear 304. The adjusting screw 305... The surface is equipped with a matching threaded transmission block 306. When the screw rotates, the transmission block 306 moves linearly along the axial direction under the action of the thread. Since the transmission block 306 is connected to the fixed block 307, it can drive the fixed block 307 to move synchronously, realizing the clamping and positioning of both ends of the spring. After the fixing is completed, the next testing stage begins. After the two ends of the spring are fixed, the tensile performance test can be started. The servo motor 201 is started through the control panel 102, and its output end drives the cam 202 to rotate. The cam 202, as a key motion conversion element, has non- The circular shape and continuously changing contour of the cam 202 can convert rotational motion into the periodic reciprocating motion required by the follower during uniform rotation. The contour change of the cam 202 contacts and pushes one end of the connecting rod 203, while the other end of the connecting rod 203 is hinged to the fixed seat 204 via a rotating shaft. The fixed seat 204 is integrally embedded in the guide groove on the inner wall of the operating table 101 and can slide linearly inside it. As the cam 202 continues to rotate, the connecting rod 203 converts the radial displacement change of the cam 202 into the reciprocating linear motion of the fixed seat 204. The motion applies a tensile load to the fixed spring, simulating the stress condition under actual working conditions. To ensure the smoothness of the tensile testing process and the accuracy of the motion trajectory, auxiliary guide structures are provided at both ends of the fixed seat 204. Specifically, the fixed seat 204 is equipped with auxiliary wheels 205 through a rotating shaft. The auxiliary wheels 205 contact the guide rail on the inner wall of the operating table 101 and roll along it, effectively reducing the frictional resistance of the fixed seat 204 in reciprocating motion, avoiding motion distortion caused by off-center loading or jamming, and improving the reliability and repeatability of the test data.

[0031] In summary: the reliable clamping of the spring is achieved through the coordinated action of the fixed motor, adjusting screw, transmission block and fixed block. Then, the servo motor drives the cam and connecting rod mechanism to drive the fixed seat to reciprocate. Combined with the guiding support of the auxiliary wheel, stable and repeatable testing of the spring's tensile performance is realized.
