Description

Technical Field

[0001] This utility model relates to the field of spring testing technology, and in particular to an S-shaped return spring resistance testing device. Background Technology

[0002] The elasticity test of a spring requires applying a certain load to the spring using a spring testing machine, measuring its deformation, calculating the spring's elastic coefficient according to Hooke's Law, and checking whether it meets the design value. Fatigue testing, on the other hand, requires simulating the stress conditions of the spring in actual operation, subjecting it to multiple cyclic loading and unloading tests to test its fatigue resistance during long-term use. The load-bearing capacity test of a spring requires applying a gradually increasing load until the spring reaches the specified deformation or fails, in order to determine the spring's maximum load-bearing capacity. When testing S-type return springs, spring breakage can cause ejection. Current technology uses a closed enclosure to protect the testing device, but this requires opening and closing the door each time the spring is tested, affecting the efficiency of the spring testing.

[0022] Please see Figures 1-4 This utility model provides an S-type return spring resistance detection device, the structure of which includes a resistance detection device 1, the resistance detection device 1 is installed at the bottom of the support box 2, and the control panel 3 is provided on the top left side of the support box 2;

[0023] The resistance testing device 1 includes a protective box 11, a resistance testing frame 12, a tensile force testing sensor 13, a servo motor 14, and a protective device 15. The protective box 11 is located on the top right side of the support box 2. The resistance testing frame 12 is installed inside the protective box 11. The tensile force testing sensor 13 is located at the bottom of the resistance testing frame 12. The servo motor 14 is installed at the bottom of the inside of the protective box 11. The protective device 15 is fixedly installed on the rear end face of the protective box 11.

[0024] The protective device 15 includes an electromagnetic adsorption device 151, a support frame 152, a protective ring 153, and a handle 154. The electromagnetic adsorption device 151 is fixedly installed on the rear end face of the inner side of the protective box 11 through the support frame 152. There are two protective rings 153, and the protective rings 153 are rotatably connected to the left and right sides of the electromagnetic adsorption device 151 respectively. The handle 154 is located on the end face of the protective ring 153.

[0025] The electromagnetic adsorption device 151 includes a mounting base 1511, an adsorption plate 1512, an iron core 1513, a copper coil 1514, and a connecting circuit line 1515. The mounting base 1511 is fixedly mounted on the end face of the support frame 152. The adsorption plate 1512 is attached to the end face of the mounting base 1511. The iron core 1513 is fixedly connected to the end face of the adsorption plate 1512, and the end face of the iron core 1513 is wound with a copper coil 1514. The copper coil 1514 is electrically connected to the connecting circuit line 1515.

[0026] The side end face of the support box 2 is provided with heat dissipation holes 4.

[0027] The bottom of the tension sensor 13 is connected to a threaded rod 16, which can be driven to move up and down by a servo motor 14, thus stretching and resetting the S-shaped return spring.

[0028] The protective ring 153 is provided with a small magnet at its end, which is conducive to attracting and connecting the two ends of the protective ring 153 together by the magnet's magnetism.

[0031] Working principle: The upper and lower ends of the S-shaped return spring to be tested are hung in the hooks 17 of the resistance testing frame 12. Pulling the handle 154 causes the two protective rings 153 to magnetically close together. If the S-shaped return spring breaks, the protective rings 153 can prevent the S-shaped return spring from being ejected and causing harm to personnel. The tension sensor 13 detects the abnormality and supplies power to the copper coil 1514 through the connecting circuit 1515, so that the copper coil 1514 is energized, causing the iron core 1513 to rotate. The broken S-shaped return spring is attracted by magnetization, which facilitates manual processing of inferior S-shaped return springs and improves the efficiency of S-shaped return spring testing. Then, the servo motor 14 engages with the threaded rod 16 to drive the resistance testing frame 12 to move downward to perform tensile testing on the S-shaped return spring. At the same time, the tension detection sensor 13 connected to the top of the threaded rod 16 can detect the tension on the S-shaped return spring. The detected data is then analyzed and processed through the control panel 3, and the resistance test data of the S-shaped return spring can be displayed.
