Description

[0001] The present invention relates to the technical field of elasticity detection, and particularly to an elasticity detection device for studying the elastic performance of a tensioner. Background Art

[0002] As a sports equipment, a tensioner is generally made of a pull ring and a spring or an elastic band. Users can complete upper limb exercises by pulling one pull ring with one hand or two pull rings with both hands. As an elastic device widely used in the fields of fitness, rehabilitation and industry, the accurate detection of the core performance index - elastic characteristics directly affects the product safety and service efficiency.

[0003] Traditional detection techniques mostly adopt static tensile tests (such as tensile displacement-load curve analysis) or single dynamic impact tests. The static tensile test relies on independent equipment to complete static stretching (such as measuring elastic modulus and yield strength). The single static test cannot capture the fatigue characteristics of materials, while the dynamic test equipment cannot simulate the continuous bidirectional stress scenario in actual use. That is, the above two methods are difficult to comprehensively evaluate the comprehensive elastic performance of the tensioner under complex working conditions. Therefore, this application proposes a solution. Summary of the Invention

[0020] Embodiment 1: Aiming at the technical problem that the comprehensive elastic performance of the tensioner cannot be comprehensively evaluated under complex working conditions in the prior art, the following technical solutions are proposed: Referring to Figure 1 - Figure 9 As shown, in this embodiment, an elastic detection device for studying the elastic performance of the tensioner includes a static and dynamic adjustment seat 5 and a locking seat 6 symmetrically and slidably arranged on the bottom plate 1. A test body displacement mechanism for the movement of the tensioner is installed through the static and dynamic adjustment seat 5; On both sides of the middle of a pair of static and dynamic adjustment seats 5, a guide rod 10 is horizontally installed through. The locking seat 6 is movably arranged outside the static and dynamic adjustment seat 5. A locking plate 20 is installed between the ends of the static and dynamic adjustment seat 5 and the locking seat 6. The locking plate 20 is connected to the static and dynamic adjustment seat 5 and the locking seat 6 respectively through pins. A lead screw 11 is horizontally installed between a pair of locking seats 6. The lead screw 11 is threadedly connected to one of the locking seats 6; A tension application mechanism is installed in the middle of the outside of the static and dynamic adjustment seat 5. The tension application mechanism includes a tensiometer body 8. The output end of the tensiometer body 8 is connected with a reverse hook rod 9 for pulling the tensioner. An expansion and contraction assembly for two-way expansion and contraction control of the tensiometer body 8 is installed outside the static and dynamic adjustment seat 5; Among them, the telescopic component includes a driving cylinder and a second motor, which are used to control the horizontal reciprocating movement of the dynamic and static adjustment seat 5. Slide rails 2 are installed on both sides of the bottom plate 1. The sliding support plate 3 and the side shift plate 4 are both slidably connected to the slide rails 2. Fiber Bragg sensors and high-speed cameras are arranged at the upper ends of the dynamic and static adjustment seat 5 and the locking seat 6. The Fiber Bragg sensors, high-speed cameras and the tensiometer body 8 are jointly communicatively connected to a control panel; It should be noted in combination with the above that the tensioner can be arranged between the tensiometer bodies 8 and is pulled through the reverse hook rod 9. The two-way telescopic control of the dynamic and static adjustment seat 5 and the locking seat 6 is completed by means of the added telescopic component, which is specifically divided into dynamic elasticity detection and static elasticity detection, and will be described one by one below: Dynamic elasticity detection: At this time, the locking seat 6 is separated from the dynamic and static adjustment seat 5, and the driving cylinders in the telescopic component are symmetrically arranged outside a pair of dynamic and static adjustment seats 5 and are used for telescopic control. The driving cylinders are started to drive the dynamic and static adjustment seat 5 to move, and the tensioner fixed between the reverse hook rods 9 is subjected to two-way and reciprocating telescopic control. During this process, the tensiometer body 8 is used to obtain the tension received by the current tensioner in real time; Static elasticity detection: At this time, the locking seat 6 is fixed to the dynamic and static adjustment seat 5 through the locking plate 20, and the second motor in the telescopic component is arranged outside the lead screw 10. The second motor is started to drive the dynamic and static adjustment seat 5 outside the lead screw 11 to move, and the tensioner fixed between the reverse hook rods 9 is subjected to one-way telescopic control. During this process, the tensiometer body 8 is used to obtain the tension received by the current tensioner in real time; Refer to Figure 1 and Figure 5 As shown, the test body displacement mechanism includes a sliding support plate 3 and a side shift plate 4 arranged on the lower side of the dynamic and static adjustment seat 5. One end of the outside of the sliding support plate 3 is provided with a first motor 12. The first motor 12 is drivingly connected with a number of adjustment wheels 18. The upper ends of the adjustment wheels 18 penetrate through the dynamic and static adjustment seat 5 and extend to the upper side. The inner sides of the a number of adjustment wheels 18 are connected with a driving gear 16 through a shaft rod 21. An auxiliary gear 17 is jointly meshed between adjacent pairs of driving gears 16. The first motor 12 on the same side drives one of the driving gears 16 to rotate to drive the adjustment wheels 18 to rotate in the same direction; When performing the elasticity detection of the tensioner, the pull rings on the tensioner are respectively placed on the adjustment wheels 18. The first motor 12 is started. The first motor 12 drives the driving gear 16 to rotate, and the adjacent driving gears 16 are driven to rotate in the same direction through the auxiliary gear 17, that is, the tensioner on the adjustment wheels 18 is subjected to continuous rotation in the same direction to complete continuous feeding, and intermittently stops at the reverse hook rod 9. The elasticity performance of the tensioner is detected by releasing the reverse hook rod 9 downward; Refer to Figure 5 and Figure 6As shown in the figure, an installation frame 7 is provided on the outer side of the dynamic and static adjustment seat 5. A fixed plate 13 is installed on the upper surface of the dynamic and static adjustment seat 5 corresponding to the installation frame 7. A top displacement rod 14 is provided at the output end of the tensiometer body 8. One end of the top displacement rod 14 extending above the dynamic and static adjustment seat 5 penetrates through the outside of the fixed plate 13 in the reverse direction and is sleeved with a spring 15. The end of the top displacement rod 14 extending inside the fixed plate 13 is sleeved with a reverse hook rod 9. The arc-shaped hook structure of the reverse hook rod 9 faces downward. Among them, the reverse hook rod 9 is movably sleeved on the top displacement rod 14. During elastic detection, the tensioner moved under the reverse hook rod 9 is fixed by reversely hooking the pull ring of the tensioner. Subsequently, the telescopic assembly respectively completes dynamic elastic detection and static elastic detection.

[0021] Referring to Figure 5 , Figure 8 and Figure 9 As shown in the figure, a through groove 19 is opened at the upper end of the dynamic and static adjustment seat 5. The adjustment wheel 18 penetrates to the upper part of the through groove 19 and is vertically aligned with the reverse hook rod 9. A wheel groove 22 is opened on the adjustment wheel 18. The wheel grooves 22 on a pair of adjacent adjustment wheels 18 intersect and overlap. In the prior art, the adjustment wheel 18 is composed of a pull ring and a spring or an elastic band. Therefore, during the continuous elastic test of the tensioner, the continuous conveying can be completed by supporting the pull ring. The adjustment wheels 18 do not contact each other and will not cause movement interference during the same-direction rotation process.

[0022] Basic principle: Taking Figure 5 as an example, during the detection process of the elastic performance of the tensioner, a tension application mechanism and a test body displacement mechanism based on the tensiometer body 8 are used to alternately perform dynamic elastic detection and static elastic detection of the tensioner, and the continuous test function can be realized in a cyclic feeding and discharging manner, which is beneficial to the comprehensive evaluation of the elastic performance of the tensioner.

[0023] Embodiment 2: This embodiment further intelligently optimizes the elastic detection of the elastic performance of the tensioner in Embodiment 1. A detection system is provided in the control panel. The detection system includes a data monitoring end, a data comparison end, an elastic evaluation and analysis end, an execution control end and a processor that are communicatively connected; The data monitoring end is used to obtain the tension value LL applied by the tensiometer body 8 to the tensioner and the external force value WL applied to the tensioner during the detection process of the elastic performance of the tensioner, and send the tension value LL and the external force value WL to the data comparison end through the processor; After receiving the tension value LL and the external force value WL, the data comparison end performs analysis operations: S1: Obtain the tensile force value LL and the external force value WL, where the tensile force value LL represents the tensile force F when the spring / elastic band in the tensioner is stretched to the limit length, and the external force value WL represents the displacement Δd when the tensioner is stretched to the limit length and the time duration Δt between the start of stretching and the occurrence time of the surface crack of the spring / elastic band of the tensioner; S2: Through the formula: , obtain the elastic force value TL, where a, b, and c are preset proportionality coefficients. The role of the preset proportionality coefficients is to assign weights to the calculation process of the elastic force value TL. If the tensile force F has a greater impact on the result of the elastic force value TL, the assigned value of the preset proportionality coefficient a corresponding to the tensile force F is larger, and here a > b > c > 0; S3: Compare and analyze the elastic force value TL with the preset elastic force threshold in the processor to obtain the evaluation information; And send the evaluation information to the elastic evaluation and analysis terminal. The elastic evaluation and analysis terminal generates an elastic force performance qualified signal and an elastic force performance unqualified signal according to the evaluation information and sends them to the execution control terminal. The generation processes of the elastic force performance qualified signal and the elastic force performance unqualified signal are as follows: When the elastic force value ≥ the elastic force threshold, generate an elastic force performance qualified signal and send it to the execution control terminal; When the elastic force value < the elastic force threshold, generate an elastic force performance unqualified signal and send it to the execution control terminal; After receiving the elastic force performance qualified signal and the elastic force performance unqualified signal, the execution control terminal controls the relevant components to act and completes the continuous cyclic test of the tensioner; The process of controlling the relevant components to act is as follows: Action 1: Start the motor 12 to drive the driving gear 16 to rotate, and the adjacent driving gears 16 drive each other to rotate in the same direction through the auxiliary gear 17, that is, the tensioner on the positioning wheel 18 is subjected to continuous rotation in the same direction to complete continuous feeding, and intermittently stops at the reverse hook rod 9, and the elastic detection of the elastic force performance of the tensioner is carried out by releasing the reverse hook rod 9 downward; Action 2: After the elastic detection is completed, the reverse hook rod 9 disengages from the tensioner, and the positioning wheel 18 continues to rotate to drive the tensioner to disengage from the detection device and continue to carry out the continuous elastic detection of the next tensioner; When generating the elastic force performance unqualified signal, the above-mentioned starting action 2 is to "remove" the unqualified tensioner so that the next tensioner to be detected can continuously enter, so that the elastic force performance detection process of the entire tensioner is carried out continuously in a cycle, optimizing the time required for manual adjustment and improving the elastic detection efficiency of the tensioner; It should be noted importantly that: for the above elastic value calculation formula, combined with the comparison and analysis process of the elastic threshold in a positive correlation relationship, it can be understood that: when the calculation result is within the threshold or exceeds the threshold range, it indicates that the current elastic value meets the requirements; conversely, if the calculation result is lower than the threshold range, that is, the elastic value does not meet the requirements.

[0024] The advantages of the optimization scheme are as follows: with the intelligent detection system combined with the auxiliary setting of the automatic control structure, the data during the elastic detection of the tensioner can be intelligently supervised and processed. The true level of data processing is reflected through the elastic performance detection method combining static detection and dynamic detection, and it is judged whether the tensioner meets the acceptance standard by whether the elastic value is within the standard threshold.

[0025] In summary: on the one hand, through the tension application mechanism and the test body displacement mechanism set based on the tension meter body 8, the dynamic elastic detection and static elastic detection of the tensioner are alternately carried out, and the continuous test function can be realized in a cyclic feeding and discharging manner, which is conducive to the comprehensive evaluation of the elastic performance of the tensioner; on the other hand, with the intelligent detection system combined with the auxiliary setting of the automatic control structure, the data during the elastic detection of the tensioner can be intelligently supervised and processed. The true level of data processing is reflected through the elastic performance detection method combining static detection and dynamic detection, and it is judged whether the tensioner meets the acceptance standard by whether the elastic value is within the standard threshold.

[0026] The above formulas are all obtained by collecting a large amount of data for software simulation and selecting a formula close to the true value. The coefficients in the formula are set by those skilled in the art according to the actual situation.
