Description

Technical Field

[0002] Materials are anything used to make products, both natural and man-made. They can be solid, liquid, or gaseous, and possess specific physical, chemical, or mechanical properties. Materials can be used in diverse applications, such as construction, automotive, aerospace, and healthcare. Tensile testing is a test method used to determine a material's maximum tensile strength when subjected to an external force. When a material is stretched, it may break or fail.

[0003] However, the current material tensile testing device is inconvenient for fixing the material during actual use, and the operator needs to clamp the material multiple times, which increases the operation time and reduces the detection speed of the tensile force, causing inconvenience to the user. Moreover, the common tensile testing device can only see one side of the tensile material during the tensile test, and cannot fully observe the fracture of the tensile part of the tensile material. This may cause some defects and damage to not be discovered in time, thereby affecting the quality and safety of the product. Utility Model Content

A clamping assembly 7 for clamping materials is provided inside the first connecting shell 5 and the second connecting shell 6. The clamping assembly 7 includes a cylinder 701. The top of the detection frame 1 is fixedly connected to a driving assembly 8 for rotating and stretching materials. The driving assembly 8 includes a motor 801. A controller body 9 is fixedly connected to one side of the front side of the detection frame 1. The controller body 9 is used to conveniently control the motor 801, the hydraulic rod 4 and the cylinder 701 to drive the work. The four corners of the bottom of the detection frame 1 are fixedly connected to support legs 10, and the support legs 10 are used to conveniently support the detection frame 1.

[0024] The motor 801 is fixed to the top of the detection frame 1, and the output end of the motor 801 passes through the interior of the detection frame 1 and is fixedly connected to the transmission rod 802. The bottom of the transmission rod 802 is rotatably connected to the interior of the detection frame 1 through a bearing. The top and bottom of the surface of the transmission rod 802 are fixedly connected to the first transmission wheel 803, and the surface of the first transmission wheel 803 is provided with a transmission belt 804. The motor 801 can be turned on to make the transmission rod 802 cooperate with the first transmission wheel 803 to rotate. At this time, the first transmission wheel 803 drives the transmission belt 804 to make the second transmission wheel 805 cooperate to rotate the first support rod 2 and the second support rod 3, thereby rotating the material for tensile testing. The inner cavity of the transmission belt 804 is connected to the second transmission wheel 805 on the side away from the first transmission wheel 803, and the interiors of the two second transmission wheels 805 are fixedly connected to the first support rod 2 and the second support rod 3 respectively.

The surface of the limit rod 15 penetrates to the outside of the extension plate 13.

[0026] When the two ends of the two sliding plates 707 are fixed to the inner walls of the first connecting shell 5 and the second connecting shell 6, the two cylinders 701 are respectively fixed to the inner walls of the first connecting shell 5 and the second connecting shell 6.

The two ends of the two sliding rods 707 are respectively fixedly connected to the interior of the first connecting shell 5 and the second connecting shell 6.

[0027] Working principle: First, place the test material flat between the two clamping plates 705, and then the cylinder 701 will be lowered to drive the movable plate 702 to move. At this time, the movable plate 702 will drive the T-shaped block 703 to descend. At that time, the sliding plate 704 will be forced to drive the clamping plate 705 to move relatively, and the protective strip 706 will make anti-slip contact with the material for clamping. Then the hydraulic rod 4 is driven to drive the first connecting shell 5 to move, thereby stretching the material. At this time, the user can observe the ruler 12 to record the stretching distance, and then turn on the motor 801 to make the transmission rod 802 cooperate with the first transmission wheel 803 to rotate. At this time, the first transmission wheel 803 drives the transmission belt 804 to make the second transmission wheel 805 cooperate to rotate the first support rod 2 and the second support rod 3, and then drive the first connecting shell 5 and the second connecting shell 6 respectively, so as to rotate the material for stretching testing, so as to facilitate comprehensive observation of the stretching position.
