Description

Technical Field

[0001] This utility model relates to the field of spring testing, and in particular to a spring elasticity performance testing device. Background Technology

[0002] As a fundamental and crucial elastic element, springs are widely used in many fields such as machinery, electronics, automobiles, and aerospace. Their elastic properties directly affect key indicators such as the quality, stability, safety, and service life of related products.

[0003] Existing spring elasticity performance testing usually involves manually hooking each spring onto a tensile testing machine for testing. However, most current tensile testing equipment can only test a single spring under single conditions and cannot test multiple springs simultaneously. This not only affects testing efficiency but also makes it difficult to comprehensively and accurately evaluate the overall performance of the spring, affecting the reliability of the test and making it very inconvenient to use.

[0004] Therefore, it is necessary to design a spring elasticity performance testing device that can perform elasticity performance testing on multiple or single springs under different tensions and heights, adapt to testing needs in different scenarios, facilitate comprehensive evaluation of spring performance, improve testing efficiency and reliability, and is easy to use. Utility Model Content

[0005] To overcome the shortcomings of most current tensile testing equipment, which can only test a single spring under a single condition and cannot test multiple springs simultaneously, thus affecting testing efficiency, making it difficult to comprehensively and accurately evaluate the overall performance of the springs, impacting testing reliability, and causing great inconvenience, this utility model provides a spring elasticity performance testing device that can test the elasticity performance of multiple or single springs under different tensile forces and heights. This device is easy to adapt to testing needs in different scenarios, facilitates comprehensive evaluation of spring performance, improves testing efficiency and reliability, and is convenient to use.

[0006] The technical solution is as follows: A spring elasticity performance testing device includes a base, a support frame, a connecting seat, a feeding component, and a testing component. The support frame is connected to the upper side of the lower part of the base, and the connecting seats are connected to the upper sides of both the left and right sides of the base. Each connecting seat is equipped with a feeding component for limiting and feeding the spring, and the support frame is equipped with a testing component for testing the elasticity performance of the spring.

[0007] As a further preferred option, the support frame is U-shaped.

[0008] As a further preferred option, it also includes collection boxes, with two collection boxes placed on the left and right sides at the bottom of the base.

[0009] As a further preferred embodiment, the feeding assembly includes a first multi-stage cylinder and a push plate. The first multi-stage cylinder is connected to the connecting seat, and the push plate is connected to the telescopic end of the first multi-stage cylinder.

[0010] As a further preferred embodiment, the detection assembly includes an electric push rod, a slider, a second multi-stage cylinder, a tension sensor, a connecting rod, a sliding frame, a scale plate, a motor, and a lead screw. The electric push rod is connected to the lower rear of the support frame, and the slider is slidably connected to the upper part of the support frame. The second multi-stage cylinder is connected to the slider, and the tension sensor is connected to the telescopic end of the second multi-stage cylinder. The connecting rod is connected to the lower side of the tension sensor. Sliding frames are slidably connected to both the front and rear parts of the support frame, and the sliding frames are slidably connected to the connecting rods. Scale plates are connected to the inner sides of both the front and rear parts of the support frame, and the sliding frames are slidably connected to the scale plates. A motor is connected to the upper left part of the support frame, and a lead screw is connected to the output shaft of the motor. The lead screw is connected to the slider via a thread.

[0011] As a further preferred option, grooves are provided on the sides of the sliding frames that are close to each other.

[0012] Beneficial effects: 1. This utility model installs one or more springs between the connecting rod and the telescopic end of the electric push rod. The springs are detected by moving the connecting rod up and down, the tension is detected by the tension sensor, and the positioning is achieved by the scale plate. This allows for the testing of the elasticity performance of multiple or single springs under different tensions and heights, making it easy to adapt to the testing needs of different scenarios, facilitating a comprehensive evaluation of spring performance, improving testing efficiency and reliability, and making it convenient to use.

[0013] 2. This utility model uses a push plate to move and limit the clamping and installation of the spring. The spring is disengaged from the spring by the telescopic end of the connecting rod or electric push rod. Then, the push plate on one side moves to push the spring into the collection box for collection and sorting. This allows for the detection of the spring clamping and limiting during loading, and the automatic sorting and unloading of the spring after detection. This facilitates the loading and unloading of springs, prevents spring displacement or falling off, and improves the stability of use. Attached Figure Description

[0021] A spring elasticity performance testing device, such as Figures 1-5 As shown, the device includes a base 1, a collection frame 2, a support frame 3, a connecting seat 4, a feeding assembly, and a detection assembly. The base 1 has two collection frames 2 placed on the lower part for collecting springs. The support frame 3 is connected to the upper side of the lower part of the base 1. The support frame 3 is U-shaped for easy support. The connecting seats 4 are connected to the upper sides of both the left and right parts of the base 1. Each connecting seat 4 is equipped with a feeding assembly for limiting and feeding the springs. The support frame 3 is equipped with a detection assembly for detecting the elasticity of the springs.

[0022] like Figure 1 and Figure 3 As shown, the feeding assembly includes a first multi-stage cylinder 5 and a push plate 6. The first multi-stage cylinder 5 is connected to the connecting seat 4, and the push plate 6 is connected to the telescopic end of the first multi-stage cylinder 5.

[0023] like Figure 2 , Figure 4 and Figure 5As shown, the detection assembly includes an electric push rod 7, a slider 8, a second multi-stage cylinder 9, a tension sensor 10, a connecting rod 11, a sliding frame 12, a scale plate 13, a motor 14, and a lead screw 15. The electric push rod 7 is connected to the lower rear of the support frame 3, and the slider 8 is slidably connected to the upper part of the support frame 3. The second multi-stage cylinder 9 is connected to the slider 8, and the tension sensor 10 is connected to the telescopic end of the second multi-stage cylinder 9. The connecting rod 11 is connected to the lower side of the tension sensor 10. The front of the support frame 3... The latter two parts are slidably connected to the sliding frame 12, and the sliding frame 12 is slidably connected to the connecting rod 11. The sliding frame 12 has a sliding groove on the side that is close to each other to facilitate the movement of the connecting rod 11. The scale plate 13 is connected to the inner side of the front and rear parts of the support frame 3, and the sliding frame 12 is slidably connected to the scale plate 13. The motor 14 is connected to the upper left part of the support frame 3, and the lead screw 15 is connected to the output shaft of the motor 14. The lead screw 15 is connected to the slider 8 by a thread.

[0024] When it is necessary to test the elasticity performance of a spring, this device can be used. The base 1 is brought into contact with the ground, and then one or more springs are lifted, positioning them between the push plates 6. Next, the first multi-stage cylinder 5 is activated, causing the push plates 6 to move and contact the springs for clamping and limiting. Then, the first multi-stage cylinder 5 is closed, and the electric push rod 7 is activated. The telescopic end of the electric push rod 7 extends and contacts the spring, hooking it onto the telescopic end. Then, the electric push rod 7 is closed, and the second multi-stage cylinder 9 is activated, causing the tension sensor 10 and the connecting rod 11 to move, allowing the sliding frame 12 to move along the support frame 3 until it reaches the spring. After the spring is positioned, the second multi-stage cylinder 9 is closed, and the motor 14 on the support frame 3 is started. The support frame 3 is U-shaped for easy support. The motor 14 drives the lead screw 15 to rotate, causing the slider 8 to move under the action of the thread. This causes the second multi-stage cylinder 9 to move, causing the connecting rod 11 to move along the groove on the sliding frame 12 and contact the spring. The spring hooks onto the connecting rod 11. Then, the motor 14 is closed, and the second multi-stage cylinder 9 operates in the reverse direction, causing the tension sensor 10 and the connecting rod 11 to move in the opposite direction and reset. This causes the sliding frame 12 to move in the opposite direction and reset. Then, the second multi-stage cylinder 9 operates again, causing the connecting rod 11 to move up and down, causing the slider 8 to move. The frame 12 moves repeatedly, thus repeatedly stretching and compressing the spring to test its elasticity. The tension sensor 10 detects the tension on the spring, and the scale plate 13 positions the frame. This allows the sliding frame 12 to move repeatedly at the same height or at different heights to test the spring. This enables the elasticity testing of multiple or single springs under different tensions and heights, adapting to testing needs in different scenarios, facilitating comprehensive evaluation of spring performance, improving testing efficiency and reliability, and providing ease of use. After testing, the second multi-stage cylinder 9 is closed, and the motor 14 operates in reverse, causing the lead screw 15 to rotate in the opposite direction. Under the action of the thread, the slider 8 moves in the opposite direction, causing the connecting... The connecting rod 11 moves in the reverse direction to reset and disengage from the spring. Then, the second multi-stage cylinder 9 operates in the reverse direction, causing the connecting rod 11 to move in the reverse direction and reset, and the sliding frame 12 to move in the reverse direction and reset. Alternatively, the electric push rod 7 operates in the reverse direction, causing its telescopic end to retract. When the spring has a problem, the first multi-stage cylinder 5 on the right operates in the reverse direction, causing the push plate 6 on the right to move in the reverse direction and reset. Then, the first multi-stage cylinder 5 on the left operates, causing the push plate 6 on the left to move and push the spring into the collection frame 2 on the right, thus disengaging the spring from the connecting rod 11. When the spring is functioning correctly, the first multi-stage cylinder 5 on the left operates in the reverse direction, causing the push plate 6 on the left to move in the reverse direction and reset.Then, the first multi-stage cylinder 5 on the right side operates, causing the push plate 6 on the right side to move and push the spring into the collection frame 2 on the left side. This disengages the spring from the telescopic end of the electric push rod 7, thus classifying and unloading the spring. Subsequently, the second multi-stage cylinder 9 operates in the opposite direction, causing the push plate 6 to move in the opposite direction and reset. This allows for both the detection of springs at the limit position and the automatic classification and unloading of springs after detection, facilitating spring loading and unloading, preventing spring displacement or detachment, and improving stability during use. The above operation is then repeated to install and test springs until all springs have been tested.
