Description

Technical Field

[0001] The utility model belongs to the technical field of testing machines, in particular to a double digital display tension and compression spring testing machine. Background Art

[0002] A machine used to test the performance and elasticity of tension and compression springs. This testing machine can perform bidirectional tension and compression tests on springs to measure their elastic modulus, yield strength, maximum load capacity and other parameters, thereby evaluating the quality and performance of the springs. This testing machine is commonly used in the spring manufacturing industry and quality control field.

[0003] A new type of spring tension and compression testing machine is disclosed in the announcement number CN218470124U, which includes a base, a slide groove is opened in the middle of the top of the base, a slider is slidably connected inside the slide groove, screw rods are rotatably connected on both sides of the inner wall of the slide groove, the screw rods are threadedly connected to the middle of the slider, an extrusion plate is fixedly installed on the top of the slider, a servo motor is fixedly installed on one side of the base, the output shaft of the servo motor is fixedly connected to one end of the screw rod, a fixed plate is fixedly installed on one side of the top of the base, and a pressure sensor is fixedly installed on one side of the fixed plate. The utility model drives the rotation of the screw rod through the installed servo motor, and drives the movement of the extrusion plate through the rotation of the screw rod, and performs an extrusion test on the spring through the movement of the extrusion plate. The hook provided at the bottom end of the gantry and the fixing ring provided at the top end of the extrusion plate facilitate the tension test, the tension and compression test of the spring, and the intuitive observation of the deformation of the spring. However, the structure of the above-mentioned new spring tension and compression testing machine is relatively simple, and the tension and pressure of the spring cannot be tested using the same device. There is a lack of corresponding auxiliary induction sensing mechanism, which is inconvenient to use. Usually, the spring tension and compression testing machine needs to perform a certain degree of displacement movement when in use. However, when performing tension and compression tests on the spring, the spring elastic force easily causes positional deviation during the movement, which is not conducive to accurate measurement and lacks flexible adjustment conditions. Therefore, it is necessary to provide a dual digital display tension and compression spring testing machine to solve the above problems. Utility Model Content

[0023] Please refer to Figure 1-5 . Double digital display tension and compression spring testing machine, including:

[0024] A stabilizing seat 1, the bottom end of which is connected to a supporting leg 2 for supporting stability, the surface of the stabilizing seat 1 is installed with a sensing mechanism 3 for measuring data and a supporting column 4 for supporting the structure, the top end of the supporting column 4 is connected to a pulling and pressing mechanism 5, and one side of the supporting column 4 is installed with a first display 6 and a second display 7.

[0025] Furthermore, the sensing mechanism 3 includes a force frame 31, which is made of steel and has the advantages of high strength, wear resistance, corrosion resistance, etc., and is suitable for bearing the heavy pressure of large mechanical equipment or heavy objects. The force frame 31 is a grid structure, and the center point of the force frame 31 is on the same horizontal line as the center point of the stable seat 1. A connecting column 32 is connected to the middle position of the force frame 31, and the internal thread of the connecting column 32 is rotatably connected to a tension and compression sensor 34. The tension and compression sensor 34 adopts an LCD810 tension and compression dual-purpose weighing force sensor, which has the advantages of compact structure, easy installation, and durability. The screw-type design is convenient for quick installation and disassembly. It can be used alone with a transmitter or with a shackle for tensile measurement. It is suitable for force measurement and control, testing machines and other force measuring devices. The surface of the tension and compression sensor 34 is provided with a receiving ring 33. The receiving ring 33 is made of stainless steel and has the advantages of high strength, corrosion resistance, wear resistance and reliability. The end of the tension and compression sensor 34 away from the connecting column 32 is threadedly connected to a first hook 35, which provides the entire device with a sensing display structure that can be used for integrated tension and compression measurement, which is convenient for different experiments and also facilitates real-time observation of data.

[0026] Furthermore, the pulling and pressing mechanism 5 includes a top fixing plate 51, which is made of stainless steel and has high strength and durability. It is suitable for occasions that need to withstand greater pressure or weight. A motor 52 is connected to one side of the top fixing plate 51, and a threaded rod 53 is installed at the output end of the motor 52, and a lifting platform 54 is sleeved on the surface of the threaded rod 53. The size and shape of the lifting platform 54 are the same as the size and shape of the receiving ring 33. A sliding engaging hole 55 and a receiving groove 56 are opened on the surface of the lifting platform 54. The internal thread of the lifting platform 54 is rotatably connected to a second hook 57. Limiting rods 58 are set on the surfaces of the top fixing plate 51 and the lifting platform 54, which provide stable conditions for the pulling and pressing process of the entire device, improve the user experience, and increase the stability of the device.

[0027] Furthermore, the supporting legs 2 are arranged in four groups, and the four groups of supporting legs 2 are symmetrically distributed, so that the entire device can be placed stably, which is conducive to the smooth progress of the tension and compression experiments.

[0028] Furthermore, a reserved hole is provided inside the receiving ring 33 to cooperate with the tension and compression sensor 34, and the inner diameter of the reserved hole is consistent with the diameter of the tension and compression sensor 34, so that the tension and compression sensor 34 can be installed and engaged with the receiving ring 33, which facilitates the fixation of the spring during the experiment, is easy to operate, and improves the user experience.

[0029] Furthermore, the limiting rods 58 are arranged in two groups, and the two groups of limiting rods 58 are symmetrically distributed, so that the lifting platform 54 can maintain a stable position when moving, and the elastic force of the spring will not affect the experiment, thereby improving the measurement accuracy.

[0030] Working principle: When in use, the two ends of the spring to be measured are respectively connected to the first hook 35 and the second hook 57, or fixed to the receiving ring 33, the tension and compression sensor 34 and the receiving groove 56, and the motor 52 inside the tension and compression mechanism 5 is started. The threaded rod 53 rotates under the action of the motor 52, and at the same time drives the lifting platform 54 to move up and down. The lifting platform 54 cooperates with the limit rod 58 to move up and down. At this time, the tension and compression sensor 34 on the surface of the receiving ring 33 inside the sensing mechanism 3 is subjected to force and collects data and displays it through the first display 6 or the second display 7 on one side of the support column 4. In this process, the force frame 31 and the connecting column 32 provide stable conditions for the receiving ring 33 and the tension and compression sensor 34, ensuring the smooth progress of the experiment. The stabilizing seat 1 and the supporting leg 2 provide basic guarantees for the stable operation of the entire device. The above is the entire working principle of the utility model.
