Technical Field
[0001] This utility model relates to the field of torsion spring testing technology, specifically a torsion spring endurance testing device. Background Technology
[0002] In mechanical manufacturing and industrial production, torsion springs are an important elastic element widely used in various mechanical equipment, automotive parts, electronic products and other fields. The torsion spring's endurance performance directly affects the quality and reliability of related equipment and products. Therefore, accurate testing of the torsion spring's endurance performance is of utmost importance.
[0003] Currently, traditional torsion spring endurance testing devices have many problems. Traditional testing devices mostly use manual torque application, which is not only labor-intensive, but also difficult to control the torque precisely. The differences in operation by different operators can also have a significant impact on the test results. Therefore, this utility model proposes a torsion spring endurance testing device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a torsion spring endurance testing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a torsion spring endurance testing device, comprising a test platform, wherein a fixed column, a torsion spring body, and testing components are provided on the test platform;
[0006] The torsion spring body is horizontally inserted and installed on the fixed post;
[0007] The test component includes a torque test block, a torque sensor is provided on the end side of the torque test block, and the torque test block is mounted on a rotating shaft, which is mounted on a fixed frame.
[0008] A toothed block extends from one end of the rotating shaft, and the toothed block meshes with the transmission teeth. The transmission teeth are connected to the output end of a reciprocating motor mounted on a fixed frame.
[0009] The reciprocating motor can drive the transmission gear to rotate, and the transmission gear drives the rotating shaft to rotate through the tooth block, which in turn drives the torque test block to rotate, applying torque to the torsion spring body. The torque sensor is used to detect the magnitude of the torque applied to the torsion spring body by the torque test block.
[0010] Preferably, the test bench is provided with a guide groove, the bottom end of the fixing frame is installed in the guide groove and connected to the screw in the guide groove, and the screw is connected to the output end of the control motor on the side wall of the test bench.
[0011] Preferably, a retaining ring is provided on the end side of the torque test block, the ring diameter of which matches the ring diameter of the torsion spring body, and a pressure sensor is provided on the inner side of the retaining ring.
[0012] Preferably, a stud extends from one side of the fixing post, and the fixing post is installed on the test bench in a spiral manner via the stud.
[0013] Preferably, a controller is integrated on the side wall of the test bench, and the controller is electrically connected to the reciprocating motor and the control motor.
[0014] Preferably, the test bench is equipped with a data display terminal, which is electrically connected to the torque sensor and the pressure sensor, and is used to receive and visualize the torque data measured by the torque sensor and the pressure data collected by the pressure sensor in real time.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) Through automated structural design, the defects of traditional manual inspection are effectively overcome. The reciprocating motor drives the shaft and torque test block to rotate through the cooperation of transmission gears and gear blocks, thereby replacing manual application of torque. Operators only need to set parameters to start the inspection process, which greatly reduces labor intensity. At the same time, the torque sensor monitors and feeds back torque data in real time. Combined with the controller's precise control of the reciprocating motor, the torque error can be controlled within a very small range. Compared with the traditional manual method, the accuracy and stability of torque application are significantly improved.
[0017] (2) A guide groove is set on the test bench, and the bottom end of the fixed frame is connected to the screw in the guide groove. The screw is driven by the control motor, so that the fixed frame can achieve precise displacement adjustment on the test bench. Through this structural design, the position of the test component can be flexibly adjusted according to the size of the torsion spring body of different specifications, ensuring that the clamping ring on the torque test block is tightly fitted with the torsion spring body. At the same time, the pressure sensor inside the clamping ring can accurately collect the pressure data of the torsion spring, thereby realizing the synchronous testing of the torsion spring torque and pressure.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a torsion spring endurance testing device, including a test platform 1, a fixed column 2, a torsion spring body 3, and a testing component 4 on the test platform 1; the torsion spring body 3 is horizontally inserted and installed on the fixed column 2; the testing component 4 includes a torque testing block 41, a torque sensor 411 is provided on the end side of the torque testing block 41, and the torque testing block 41 is installed on a rotating shaft 42, which is installed on a fixed frame 5; a toothed block 43 extends from one end of the rotating shaft 42, and the toothed block 43 meshes with a transmission tooth 44, which is connected to the output end of a reciprocating motor 45 installed on the fixed frame 5; the reciprocating motor 45 can drive the transmission tooth 44 to rotate, and the transmission tooth 44 drives the rotating shaft 42 to rotate through the toothed block 43, thereby causing the rotating shaft 42 to drive the torque testing block 41 to rotate, applying torque to the torsion spring body 3; the torque sensor 411 is used to detect the magnitude of the torque applied to the torsion spring body 3 by the torque testing block 41.
[0025] Driven by the reciprocating motor 45, the transmission gear 44 and the gear block 43 work together to drive the rotating shaft 42 and the torque test block 41 to rotate, thereby replacing manual application of torque. Operators only need to set parameters to start the testing process, which greatly reduces labor intensity. At the same time, the torque sensor 411 monitors and feeds back torque data in real time. Combined with the precise control of the reciprocating motor 45 by the controller 11, the torque error can be controlled within a very small range. Compared with the traditional manual method, the accuracy and stability of torque application are significantly improved.
[0026] Please see Figures 1 to 4The test bench 1 is provided with a guide groove 13. The bottom end of the fixing frame 5 is installed in the guide groove 13 and connected to the screw 48 in the guide groove 13. The screw 48 is connected to the output end of the control motor 49 on the side wall of the test bench 1.
[0027] Please see Figures 1 to 4 A clamping ring 46 is provided on the end side of the torque test block 41. The ring diameter of the clamping ring 46 matches the ring diameter of the torsion spring body 3. A pressure sensor 47 is provided inside the clamping ring 46.
[0028] Please see Figures 1 to 4 A stud 21 extends from one side of the fixed post 2. The fixed post 2 is installed on the test bench 1 by means of the stud 21. The screw installation structure allows the fixed post 2 to be quickly disassembled and replaced. When it is necessary to test different types or specifications of torsion spring bodies 3, the operator can quickly replace the fixed post 2 with a suitable one.
[0029] Please see Figures 1 to 4 A controller 11 is integrated on the side wall of the test bench 1. The controller 11 is electrically connected to the reciprocating motor 45 and the control motor 49. In use, the controller 11 can achieve intelligent linkage control of the reciprocating motor 45 and the control motor 49 through electrical connection. During the test, the controller 11 can use PLC programming technology to preset programs or test requirements to accurately control the frequency and force of torque application of the reciprocating motor 45, as well as the adjustment of the position of the fixed frame 5 by the control motor 49. There is no need for frequent manual intervention, which greatly improves the automation of the test process, reduces manpower input, and improves test efficiency.
[0030] Please see Figures 1 to 4 The test bench 1 is equipped with a data display terminal 12, which is electrically connected to the torque sensor 411 and the pressure sensor 47. It is used to receive and visualize the torque data measured by the torque sensor 411 and the pressure data collected by the pressure sensor 47 in real time. Through the electrical connection between the data display terminal 12 and the torque sensor 411 and the pressure sensor 47, the test data can be visualized in real time, which makes it easy for operators to quickly grasp the test results. In addition, the intuitive data display also provides convenience for subsequent data statistics, comparative analysis and quality assessment of the torsion spring body 3, improving the efficiency and scientific nature of the test.
[0031] In use, the reciprocating motor 45 drives the transmission gear 44 and the gear block 43 to mesh, which drives the rotating shaft 42 to rotate. This causes the torque test block 41 to apply torque to the torsion spring body 3. The torque sensor 411 detects the torque magnitude in real time. At the same time, the position of the fixing frame 5 can be adjusted by the screw 48 and the control motor 49, so that the pressure sensor 47 on the inner side of the tight ring frame 46 abuts against the torsion spring body 3, compressing the torsion spring body 3. This allows the pressure data of the torsion spring body 3 to be acquired simultaneously, achieving accurate detection of multiple parameters of torque and pressure, and comprehensively evaluating the torsion spring's endurance performance.
[0032] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
