[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-4 A tensile strength detection device includes a support column 1, an outer frame 2 is arranged on the top of the support column 1, a bottom plate 3 is installed at the bottom of the outer frame 2, a first clamp 4 is installed on one side of the inner wall of the outer frame 2, a force sensor 9 is installed on the first clamp 4, and the force sensor 9 measures the force received by utilizing the strain effect generated when an object is subjected to force, a hydraulic mechanism 5 is installed on the other side of the inner wall of the outer frame 2, an output end of the hydraulic mechanism 5 is connected to a mounting seat 6, a second clamp 7 is installed on one side of the mounting seat 6, and a vacuum clamp 8 is installed on the top of the mounting seat 6.
[0020] The outer frame 2 is in the shape of a rectangular parallelepiped frame with upper and lower openings. A partition is arranged on the inner wall of the outer frame 2, which divides the outer frame 2 into two parts. The bottom plate 3 is in a "V" shape and is arranged between one side of the inner wall of the outer frame 2 and the partition, and can support the aluminum strip to be tested.
[0021] Mounting holes are respectively opened on the other side of the inner part of the outer frame 2 and at the corresponding positions of the partition. Two mounting holes are respectively passed through the two ends of the hydraulic mechanism 5. The hydraulic mechanism 5 is composed of a hydraulic pump, a hydraulic cylinder and a hydraulic control valve. The hydraulic pump draws hydraulic oil from the hydraulic oil tank and applies pressure, and then transfers the hydraulic oil to the hydraulic cylinder through the hydraulic pipeline. The piston in the hydraulic cylinder moves under the action of the hydraulic pressure, thereby pulling the aluminum bar to be tested.
[0022] The second clamp 7 is located below the vacuum clamp 8, and a vacuum suction cup is provided on the vacuum clamp 8. The bottom surface of the vacuum suction cup is flush with the opening of the clamping end of the second clamp 7. The vacuum clamp 8 generates negative pressure inside to form a vacuum on the working surface, thereby fixing the workpiece by adsorbing the surface of the workpiece. When negative pressure is generated, the air pressure holds the workpiece firmly on the vacuum clamp 8 and prevents it from sliding or moving.
[0023] When using the device, firstly, connect the electrical equipment in the device to an external power source, place the device at a designated working position, and cooperate with the second clamp 7 and the vacuum clamp 8 to provide uniform stress distribution during the aluminum strip test, thereby improving the accuracy of the test results. Under the action of the uniform clamping force, the aluminum strip can more accurately reflect its true tensile strength, reduce additional errors introduced in the test, and ensure the consistency of the aluminum strip during the test.
[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
