[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The present invention provides a technical solution: a spring tension testing device comprising a base 1, a drawer 2 mounted on one side of the base 1, a first handle 3 mounted on the surface of the drawer 2, a protective assembly mounted on the top of the base 1 to enhance the safety and efficiency of the tension testing device, and a clamping assembly mounted within the protective assembly to enhance the stability of the tension testing device. The base 1 ensures the stability of the entire testing device during tension testing, effectively preventing the device from shaking or tilting during testing, thereby ensuring the accuracy and reliability of the test results.

[0023] The protective assembly includes a protective body 4, the bottom of which is connected to the top of the base 1. A control panel 5 is mounted on the top of the protective body 4. A protective door 6 is mounted on the surface of the protective body 4. A hinge 7 is mounted on one side of the connection between the protective door 6 and the surface of the protective body 4. A second handle 8 is mounted on the surface of the protective door 6. The interaction between the protective body 4 and the protective door 6 completely encloses the spring during the inspection process within the protective body 4, effectively preventing the safety hazard of low-quality springs breaking due to the tension during the inspection process, which could cause splashing and injury.

[0024] Specifically, the protective door 6 is made of transparent tempered glass with a tempering degree of 2-4N / cm, so that the morphological changes of the spring can be observed. Experimental tests have shown that the impact force generated by a spring with a diameter of 0.2cm and a height of 10cm when it breaks and splashes is generally less than 30 joules, while tempered glass can withstand energy impacts between 60-100 joules. Therefore, by setting up the protective door 6 and completely enclosing the spring during the detection process inside the protective body 4, it is possible to avoid the spring breaking and splashing during the detection process to injure people, thereby improving safety.

[0025] By installing a control panel 5 for displaying various parameters and results during the detection process, the operator can intuitively see the various parameters and results during the detection process, making it easier to make accurate judgments; the hinge 7 is installed on one side of the connection between the protective door 6 and the surface of the protective body 4, and cooperates with the first handle 3 to realize the opening and closing function of the protective door 6.

[0026] Sliding grooves 9 are provided on both sides of the inner wall of the protective body 4, and a motor 10 is installed at the bottom of the sliding groove 9. A partition 11 is installed at the end of the sliding groove 9 close to the motor 10. The output end of the motor 10 passes through the partition 11 and is installed with a first screw 12. The end of the first screw 12 away from the motor 10 is connected to the top of the sliding groove 9; a slider 13 is threadedly installed on the surface of the first screw 12, and the surface of the slider 13 slides in contact with the inner wall of the sliding groove 9. A connecting plate 14 is installed on the surface of the slider 13, and a tensile tester 15 is installed on the lower surface of the connecting plate 14. By driving the first screw 12 to rotate forward and backward through the motor 10, the slider 13 can drive the connecting plate 14 to move up and down; the sliding groove 9 is designed on both sides of the inner wall of the protective body 4, providing a stable motion track for the slider 13, so that the slider 13 can move smoothly along the sliding groove 9 under the drive of the motor 10, thereby driving the connecting plate 14 and the clamping assembly to perform precise displacement; the tension tester 15 measures and records the magnitude of the force applied to the spring during the stretching process, which can ensure the accuracy and reliability of the test results and provide key data for evaluating the performance of the spring.

[0027] The clamping assembly includes a first connecting block 16, the top of the first connecting block 16 is connected to the detection end of the tension tester 15, the lower surface of the first connecting block 16 is provided with a first groove 17, and the top of the inner wall of the first groove 17 is installed with an elastic spring 18; the inner wall of the first groove 17 is provided with a second groove 19, and the inner wall of the second groove 19 is installed with a second connecting block 20, the bottom of the second connecting block 20 is installed with a connecting column 21, and the lower surface of the connecting column 21 is installed with a first servo electric clamp 22; the clamping assembly also includes a supporting plate 23, the bottom of the supporting plate 23 is connected to the top of the base 1, and the upper surface of the supporting plate 23 is installed with a second servo electric clamp 24.

[0028] The first connecting block 16 is a key component connecting the tension tester 15 and the first servo electric clamp 22. It is connected to the detection end of the tension tester 15 to transmit the tension of the spring to the tension tester 15 for measurement. The cooperation of the first connecting block 16, the second connecting block 20, the connecting column 21 and the first servo electric clamp 22 can stably clamp the spring to be tested. The cooperation of the bearing plate 23 and the second servo electric clamp 24 can stably fix the spring to be tested, ensuring that the spring can maintain a stable position and state during the tension test process. ; By rotating the first servo electric clamp 22, the connecting column 21 and the second connecting block 20 are driven to rotate to a certain angle inside the first groove 17 and the second groove 19 respectively. At this time, the elastic force of the elastic spring 18 will pop out the second connecting block 20, the connecting column 21 and the first servo electric clamp 22, thereby achieving the purpose of quickly disassembling the first servo electric clamp 22; the drawer 2 can be opened by pulling the first handle 3, and the disassembled first servo electric clamp 22 can be placed inside the drawer 2 to facilitate maintenance and care of the first servo electric clamp 22.

[0029] Specifically, it can be proposed to set different detection parameter programs through the software interface of the control panel 5 to realize one-click detection of springs of different specifications, thereby improving the degree of automation and ease of operation. The tension tester 15 is electrically connected to the control panel 5, and the motor 10, the first servo electric clamp 22 and the second servo electric clamp 24 are electrically connected, and the motor 10, the first servo electric clamp 22 and the second servo electric clamp 24 can be controlled through the control panel 5.

[0030] A tension value A is preset via the control panel 5;

[0031] Measure the length of the test spring using a measuring tool to obtain the original length C;

[0032] The specific steps are:

[0033] Place the detection spring between the first servo electric clamp 22 and the second servo electric clamp 24, and control the first servo electric clamp 22 and the second servo electric clamp 24 to open and close through the control panel 5 to clamp and fix the detection spring;

[0034] The motor 10 is started through the control panel 5, and then the first servo electric clamp 22 pulls the test spring. After the tension tester 15 detects that the applied tension reaches the preset tension value A, the control panel 5 automatically stops applying the tension, so that the spring remains in the current state for 5-10 seconds;

[0035] The control panel 5 controls the first servo electric clamp 22 to release the fixing of the detection spring, and then controls the second servo electric clamp 24 to release the fixing of the detection spring;

[0036] Open the protective door 6 to take out the detection spring, and observe the surface of the detection spring to see if there is any breakage. Then, test the length of the detection spring to obtain the length C after testing. Compare the original length B with the length C after testing to obtain the difference D. Through the numerical value of the difference D, we can intuitively judge the changes in the spring under the action of tension, that is, the tensile performance, which provides a reliable basis for judging the quality of the spring.

[0037] In addition, when the preset tension A remains unchanged, springs of different specifications and models can be replaced for testing, and the test results of springs of different specifications and models can be recorded separately. By comparing multiple sets of test results, the performance of different springs under the same tension test can be intuitively observed.

[0038] In addition, the preset tension A can also be adjusted to perform tension tests of different degrees on springs of the same specification and model.

[0039] Through the cooperation of the above-mentioned testing steps and the testing device, springs of various models and specifications can be tested, which reflects the versatility, convenience and reliability of the testing device.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
