Description

Technical Field

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

[0002] As a piece of sports equipment, the puller is generally made of pull rings and springs or elastic bands. Users complete upper limb exercises by pulling one of the pull rings with one hand or both pull rings with both hands. As an elastic device widely used in fitness, rehabilitation and industrial fields, the core performance indicator of the puller - the precise detection of elastic characteristics - directly affects product safety and effectiveness.

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

DETAILED DESCRIPTION

[0035] The technical solutions of the present application will be described clearly and completely below in combination with embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Embodiment one: in view of the technical problem that the existing technology cannot comprehensively evaluate the comprehensive elastic performance of the tensioner under complex working conditions, the following technical solution is proposed:

[0037] Referring to Figure 1 - Figure 9 In the present embodiment, the elastic detection device based on the elastic performance of the tensioner includes a dynamic-static adjustment seat 5 and a locking seat 6 symmetrically and slidably arranged on a bottom plate 1, and a test body displacement mechanism for tensioner movement is installed through the dynamic-static adjustment seat 5.

[0038] A pair of dynamic-static adjustment seats 5 have a guide rod 10 horizontally installed on both sides of the middle part, the locking seat 6 is movably arranged on the outside of the dynamic-static adjustment seat 5, and the locking plate 20 is jointly installed between the end parts of the dynamic-static adjustment seat 5 and the locking seat 6, the locking plate 20 is connected with the dynamic-static adjustment seat 5 and the locking seat 6 through a pin, and a screw rod 11 is jointly horizontally installed between a pair of locking seats 6, and the screw rod 11 is threadedly connected with one of the locking seats 6.

[0039] A tension applying mechanism is installed in the middle of the outer side of the dynamic and static adjustment seat 5. The tension applying mechanism includes a tension meter body 8. The output end of the tension meter body 8 is connected to an anti-hook rod 9 for pulling the tensioner. A telescopic component for bidirectional telescopic control of the tension meter body 8 is installed on the outer side of the dynamic and static adjustment seat 5.

[0040] Among them, the telescopic assembly includes a driving cylinder and a motor 2, 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 base plate 1. The sliding support plate 3 and the side shift plate 4 are both slidably connected to the slide rails 2. The upper ends of the dynamic and static adjustment seat 5 and the locking seat 6 are provided with a fiber optic Bragg grating sensor and a high-speed camera. The fiber optic Bragg grating sensor, the high-speed camera and the dynamometer body 8 are connected to a control panel for communication;

[0041] In conjunction with the above, it is necessary to explain that the tensioner can be set between the tension meter body 8 and complete the pulling through the reverse hook rod 9, and the two-way telescopic control of the dynamic and static adjustment seat 5 and the locking seat 6 is completed by the added telescopic assembly. It is specifically divided into dynamic elasticity testing and static elasticity testing, which are explained one by one below:

[0042] Dynamic elasticity test: At this time, the locking seat 6 is separated from the dynamic and static adjustment seat 5, and the driving cylinder in the telescopic assembly is symmetrically arranged outside the pair of dynamic and static adjustment seats 5 and is used for telescopic control. The driving cylinder is activated to drive the dynamic and static adjustment seats 5 to move, and the tensioner fixed between the anti-hook rods 9 is subjected to bidirectional and reciprocating telescopic control. During this process, the tensioner is currently subjected to real-time acquisition of the tension through the tension meter body 8;

[0043] Static elasticity test: 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 assembly is set outside the screw rod 11. When the second motor is started, it drives the dynamic and static adjustment seat 5 outside the screw rod 11 to move, and the tensioner fixed between the anti-hook rods 9 is subject to unidirectional telescopic control. During this process, the tensioner is currently subjected to real-time acquisition of the tension through the tension meter body 8;

[0044] Reference 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. A motor 12 is installed at one end of the outer side of the sliding support plate 3. The motor 12 is driven and connected to a plurality of positioning wheels 18. The upper end of the positioning wheel 18 passes through the dynamic and static adjustment seat 5 and extends to the upper side. The inner side of the plurality of positioning wheels 18 is connected to a driving gear 16 through a shaft 21. An auxiliary gear 17 is engaged between an adjacent pair of driving gears 16. The motor 12 on the same side drives one of the driving gears 16 to rotate, driving the positioning wheels 18 to rotate in the same direction.

[0045] When testing the elasticity of the tensioner, the pull rings on the tensioner are placed on the positioning wheel 18 respectively, and the motor 12 is started. The motor 12 drives the drive gear 16 to rotate, and the adjacent drive gear 16 is driven by the auxiliary gear 17 to complete the same-direction rotation. That is, the tensioner on the positioning wheel 18 is subjected to continuous same-direction rotation to complete continuous feeding, and intermittently stops at the anti-hook rod 9. The elasticity test of the elastic performance of the tensioner is carried out by releasing the anti-hook rod 9 downward;

[0046] Reference Figure 5 and Figure 6 As shown, a mounting frame 7 is provided on the outer side of the dynamic and static adjustment seat 5, and a fixed plate 13 is installed on the upper surface of the dynamic and static adjustment seat 5 corresponding to the mounting frame 7. A push rod 14 is provided at the output end of the dynamometer body 8. The push rod 14 extends to one end above the dynamic and static adjustment seat 5 and passes through the outer side of the fixed plate 13 in reverse and is sleeved with a spring 15. The push rod 14 extends to the end inside the fixed plate 13 and is sleeved with the anti-hook rod 9. The arc-shaped hook structure of the anti-hook rod 9 faces downward, and the anti-hook rod 9 is movably sleeved on the push rod 14. During elasticity testing, the tensioner moved under the anti-hook rod 9 is fixed by reversely hooking the pull ring of the tensioner, and then the telescopic assembly completes dynamic elasticity testing and static elasticity testing respectively.

[0047] Reference Figure 5 、 Figure 8 and Figure 9 As shown, a through slot 19 is provided at the upper end of the dynamic and static adjustment seat 5, and the positioning wheel 18 passes through the through slot 19 and is vertically aligned with the anti-hook rod 9. A wheel groove 22 is provided on the positioning wheel 18, and the wheel grooves 22 on an adjacent pair of positioning wheels 18 are staggered and overlapped. In the prior art, the positioning wheel 18 is composed of a pull ring and a spring or an elastic band. Therefore, when conducting a continuous elastic test of the tensioner, continuous transportation can be completed by supporting the pull ring. The positioning wheels 18 do not contact each other, and no motion interference will be caused during the same-direction rotation.

[0048] Basic principle: Figure 5 To illustrate, in the process of testing the elastic performance of the tensile device, the tension applying mechanism and the test body displacement mechanism set based on the tensile gauge body 8 are used to realize the alternation of dynamic elastic testing and static elastic testing of the tensile device, and the continuous testing function can be realized in a cyclic feeding and discharging manner, which is conducive to the comprehensive evaluation of the elastic performance of the tensile device.

[0049] Example 2: This example further intelligently optimizes the elasticity detection of the elastic performance of the tensioner in Example 1. A detection system is provided in the control panel, and the detection system includes a data monitoring terminal, a data comparison terminal, an elasticity evaluation and analysis terminal, an execution control terminal, and a processor that are communicatively connected.

[0050] The data monitoring end is used to obtain the tension value LL and the external force value WL applied to the tensioner by the tension meter body 8 during the elastic performance test of the tensioner, and send the tension value LL and the external force value WL to the data comparison end via the processor;

[0051] The data comparison terminal performs analysis operations after receiving the tension value LL and the external force value WL:

[0052] S1: Obtain the tension value LL and the external force value WL, where the tension value LL represents the tension F when the spring / elastic band in the tensioner is stretched to its limit length, and the external force value WL represents the displacement Δd when the tensioner is stretched to its limit length and the time Δt between the start of stretching and the appearance of surface cracks on the spring / elastic band of the tensioner;

[0053] S2: Formula: , the elastic force value TL is obtained, where a, b, and c are preset proportional coefficients. The preset proportional coefficients are used to assign weights to the calculation process of the elastic force value TL. If the tension F has a greater impact on the result of the elastic force value TL, the larger the assigned value of the preset proportional coefficient a corresponding to the tension F, and here a>b>c>0;

[0054] S3: Compare and analyze the elastic force value TL with the elastic force threshold preset in the processor to obtain evaluation information;

[0055] The evaluation information is sent to the elasticity evaluation and analysis terminal, which generates a qualified elasticity performance signal and a failed elasticity performance signal based on the evaluation information and sends them to the execution control terminal. The generation process of the qualified elasticity performance signal and the failed elasticity performance signal is as follows:

[0056] When the elastic force value is greater than or equal to the elastic force threshold, a qualified elastic force performance signal is generated and sent to the execution control end;

[0057] When the elastic force value is less than the elastic force threshold, an elastic force performance failure signal is generated and sent to the execution control end;

[0058] After receiving the elastic performance qualified signal and the elastic performance unqualified signal, the execution control end controls the actions of the relevant components and completes the continuous cycle test of the tensioner;

[0059] The process of controlling the actions of related components is as follows:

[0060] Action 1: Start the motor 12 to drive the drive gear 16 to rotate, and the adjacent drive gear 16 is driven by the auxiliary gear 17 to complete the same direction rotation, that is, the tensioner on the positioning wheel 18 is subjected to continuous same direction rotation to complete continuous feeding, and intermittently stops at the anti-hook rod 9, and the elasticity performance of the tensioner is tested by releasing the anti-hook rod 9 downward;

[0061] Action 2: After the elasticity test is completed, the anti-hook rod 9 is separated from the tensioner, and the positioning wheel 18 continues to rotate to drive the tensioner to separate from the detection device, and continue to perform continuous elasticity testing on the next tensioner;

[0062] When an unqualified elastic performance signal is generated, the second starting action is to "remove" the unqualified tensioner to facilitate the continuous entry of the next tensioner to be tested, thereby making the entire tensioner elastic performance testing process continuous and cyclical, optimizing the time required for manual adjustment and improving the efficiency of tensioner elasticity testing;

[0063] It is important to note that the above elasticity calculation formula, combined with the positive correlation and analysis process with the elasticity threshold, can be understood as follows: when the calculation result is within or exceeds the threshold, it means that the current elasticity value meets the requirements; conversely, if the calculation result is below the threshold, the elasticity value does not meet the requirements.

[0064] The advantages of the optimization scheme are: the intelligent detection system is combined with the auxiliary setting of the automatic control structure, so that the data of the tensioner during the elastic detection process can be intelligently supervised and processed, and the elastic performance detection method combining static detection and dynamic detection is used to feedback the actual level of data processing, and whether the tensioner meets the acceptance criteria can be judged by whether the elastic value is within the standard threshold.

[0065] In summary, the tension applying mechanism and the test body displacement mechanism provided on the tensile gauge body 8 enable alternating dynamic and static elasticity testing of the tensile device, and enable continuous testing in a cyclic feeding and discharging manner, thereby facilitating a comprehensive evaluation of the elastic performance of the tensile device.

[0066] On the other hand, the intelligent detection system is combined with the auxiliary setting of the automatic control structure, so that the data of the tensioner during the elastic detection process can be intelligently supervised and processed, and the elastic performance detection method combining static detection and dynamic detection is used to feedback the actual level of data processing, and whether the tensioner meets the acceptance criteria can be judged by whether the elastic value is within the standard threshold.

[0067] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by those skilled in the art according to actual conditions. The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
