Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tensile strength testing machines, and particularly relates to a tensile strength testing machine with a fixing component. Background Art
[0002] A tensile strength testing machine is a precision device used to determine the maximum stress and corresponding deformation that a material can withstand during the tensile process. It usually consists of a fixing component, a moving component, a driving system, a control system, etc. The fixing component provides stable support and clamping for the test, ensuring that the material does not slide or loosen during the test. During the test, a force is applied through the driving system to stretch the material between the fixing components, and at the same time, the control system records the force and displacement data, and calculates the tensile strength of the material.
[0003] When using a traditional tensile strength testing machine, first, a material sample to be tested needs to be placed in the fixing component of the testing machine, such as a fixture, to ensure that the sample is firmly fixed and prevent it from sliding during the test. Then, parameters such as the test speed and force are set through the controller. After the test starts, a force is applied through the driving system, such as a motor or a hydraulic system, to uniformly stretch the sample between the fixing components. At the same time, the sensors built into the testing machine will record the force and displacement data of the sample in real time.

A rack 10 is slidably connected inside the fixed seat 6. The gear 9 meshes with the rack 10. The outer wall of the rack 10 slides inside the placement table 3. The upper surface of the rack 10 is fixedly connected to a sliding seat 11. The lower surface of the sliding seat 11 slides on the upper surface of the placement table 3. A clamping assembly is arranged on the outer wall of the sliding seat 11. The clamping assembly is used for clamping and fixing the workpiece. The clamping assembly includes a fixture 12. The outer wall of the fixture 12 is fixedly connected to the outer wall of the sliding seat 11. A rubber pad 23 is fixedly connected to the outer wall of the fixture 12;
[0029] Specifically, first place one end of the workpiece above the placement table 3, and then rotate the rotating rod 4 to drive the worm 5 to rotate inside the fixed seat 6. Due to the meshing between the worm 5 and the worm gear ring 7, the worm gear ring 7 rotates with the rotation of the worm 5, thereby driving the internal gear ring 8 to rotate through the worm gear ring 7. Through the meshing relationship between the internal gear ring 8 and the gear 9, the three gears 9 inside the fixed seat 6 rotate synchronously with the rotation of the internal gear ring 8. Finally, through the meshing between the gear 9 and the rack 10, the three racks 10 slide inside the placement table 3 and the fixed seat 6 with the rotation of the gear 9, thereby driving the three sliding seats 11 above to move, and further driving the fixture 12 and the rubber pad 23 to fix the movement of the workpiece through the sliding seat 11. Then fix the other end of the workpiece through the fixture 12 on one side of the upper fixing plate 20, achieving the effect of fixing the workpiece.
[0030] In another embodiment of the present invention, refer to Figure 1 and Figure 4, a support 13 is fixedly connected to the upper surface of the workbench 1. A chute 22 is provided inside the support 13. A motor 14 is fixedly connected to the top of the support 13. The output end of the motor 14 is fixedly connected to a toothed concave wheel 15. The toothed concave wheel 15 is rotatably connected inside the support 13. A toothed transmission belt 16 is slidably connected inside the support 13. The toothed concave wheel 15 meshes with the toothed transmission belt 16. A threaded rod 17 is fixedly connected inside the toothed concave wheel 15. The threaded rod 17 is rotatably connected inside the support 13. A sliding sleeve 18 is threadedly connected to the outer wall of the threaded rod 17.

The outer wall of the limiting block 21 is slidably connected inside the support 13;
[0031] Specifically, start the motor 14 to drive the toothed concave wheel 15 to rotate. Through the meshing relationship between the toothed concave wheel 15 and the toothed transmission belt 16, the toothed transmission belt 16 drives the toothed concave wheels 15 on both sides to rotate synchronously, thereby driving the two threaded rods 17 to rotate synchronously. Then, through the threaded relationship between the threaded rod 17 and the sliding sleeve 18, the sliding sleeve 18 slides on the outer wall of the threaded rod 17. Furthermore, the fixing plate 20 is driven to move up and down through the connecting plate 19. Then, one end of the workpiece is driven to move through the movement of the fixing plate 20, realizing the tensile strength test. During this process, the movement of the fixing plate 20 will drive the limiting block 21 to slide inside the chute 22, improving its stability.
[0032] Working principle: When the tensile strength tester of the fixing component needs to be used, first place one end of the workpiece above the placement table 3. Rotate the rotating rod 4 to drive the worm 5 to rotate, thereby driving the internal gear ring 8 to rotate through the worm gear ring 7, and then driving the three gears 9 inside the fixing seat 6 to rotate synchronously. The gears 9 mesh with the racks 10, causing the three racks 10 to slide inside the placement table 3 and the fixing seat 6, driving the sliding seat 11 to move, and fixing the workpiece through the fixture 12 and the rubber pad 23;
[0033] In addition, start the motor 14 to drive the toothed concave wheel 15 to rotate. Through the meshing of the toothed transmission belt 16, the toothed concave wheels 15 on both sides rotate synchronously, and then drive the threaded rod 17 to rotate, causing the sliding sleeve 18 to slide on the outer wall of the threaded rod 17. Then, the fixing plate 20 is driven to move up and down through the connecting plate 19, realizing the tensile strength test of the workpiece. During this process, the movement of the fixing plate 20 drives the limiting block 21 to slide inside the chute 22 to improve the stability of the test
