The traditional carbon steel tensile testing equipment consists of lifting equipment, two clamps, a fixed cylindrical frame, a computer, and other equipment. The two clamps are respectively fixed on the two fixed cylindrical frames, and the two cylindrical frames are respectively fixed on the lifting equipment and the desktop. A lever arm is provided on the clamp, and the user clamps the clamp by rotating the lever arm. After the lifting equipment drives one of the clamps to stretch upward and the tested plate breaks, the stretching automatically stops. However, the strength and toughness of nuclear power carbon steel are very high, and the process of rotating the lever arm to clamp the clamp is very laborious, which increases the operation difficulty to a certain extent and brings inconvenience to the user. In order to solve the deficiencies of the prior art, we propose a tensile testing equipment for nuclear power carbon steel. Content of the Utility Model

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] The present utility model uses a tightening and loosening component, including a motor and two driving rods, to fix the fixed bracket on the outer wall of the fixed cylindrical frame, fixedly connect one side of the two driving rods to the left and right side edges of the outer wall of the lever arm respectively, and fixedly connect the other side of the two driving rods to the rotating bracket.

[0020] To make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0021] As shown in Figure 1 to Figure 4 An embodiment of the utility model provides a nuclear power carbon steel tensile test device, including a base 1. A lifting device 2 is arranged on the top of the base 1. A fixed cylindrical frame 3 is arranged on one side of the lifting device 2. A lever arm 4 is arranged on one side of the fixed cylindrical frame 3. A fixture 5 is arranged on one side of the lever arm 4. A tightening and loosening component 6 is arranged on one side of the fixture 5. An auxiliary measuring component 7 is arranged inside the fixture 5;

[0022] The tightening and loosening assembly 6 includes a fixed bracket 61 which is fixedly installed on the outer wall of the fixed cylindrical bracket 3. A first spur gear 62 and a rotating bracket 63 are rotatably connected to the outer wall of the fixed bracket 61. The rotating bracket 63 is fixedly connected to the top surface of the first spur gear 62. A motor 64 is fixedly installed on the outer wall of the fixed bracket 61. One end of the rotating shaft of the motor 64 is fixedly connected to a second spur gear 65. The second spur gear 65 meshes with the first spur gear 62. A transmission rod 66 is fixedly connected to one side outer surface of the rotating bracket 63.

[0023] Among them, the lever arm 4 is used to control the clamp 5 to clamp the plate. There are two fixed cylindrical brackets 3, lever arms 4, clamps 5 and tightening and loosening assemblies 6, which are symmetrically arranged at the top of the base 1 and the bottom of the lifting device 2 respectively.

[0024] The second spur gear 65 can drive the first spur gear 62 and the rotating bracket 63 to rotate around the outer wall of the fixed bracket 61.

[0025] Among them, in each tightening and loosening assembly 6, there are two transmission rods 66, which are symmetrically distributed on the left and right sides of the rotating bracket 63 and are fixedly connected to the left and right side edges of the outer wall of one of the lever arms 4 respectively.

[0026] By rotating the rotating bracket 63, the two transmission rods 66 can be driven to rotate, and the lever arm 4 can be driven to rotate. Since the two transmission rods 66 are fixedly connected to the left and right side edges of the outer wall of the lever arm 4, the rotating force is maximized through the lever principle.

[0027] Among them, the auxiliary measurement assembly 7 includes a connecting rod 71 which is slidably connected to the inner wall of the upper clamp 5. A threaded rod 72 is threadedly connected to the inner wall of the connecting rod 71. The threaded rod 72 is rotatably connected to the inner wall of the upper clamp 5. The top end of the threaded rod 72 is fixedly connected to a first bevel gear 73. A second bevel gear 74 meshes with the outer edge of the first bevel gear 73. One end of the rotating shaft of the second bevel gear 74 is fixedly connected to a knob 75.

[0028] By rotating the threaded rod 72, the connecting rod 71 can slide up and down along the direction of the threaded rod 72.

[0029] Among them, the auxiliary measurement assembly 7 further includes a scale 76 and a baffle 77. The scale 76 is fixedly connected to the bottom surface of the connecting rod 71 and is slidably connected to the inner wall of the lower clamp 5. The baffle 77 is fixedly connected to the outer wall of the scale 76.

[0030] When the connecting rod 71 slides up and down, it will drive the scale 76 and the baffle 77 to slide up and down.

[0031] Among them, the scales of the scale 76 are arranged from top to bottom, and the bottom surface of the baffle 77 is aligned with the zero scale line of the scale 76, so that the zero scale of the scale 76 can be aligned with the top surface of the lower fixture 5 before the tensile test;

[0032] By aligning the zero scale of the scale 76 with the top surface of the lower fixture 5 before the tensile test, after the lifting device 2 drives the upper fixture 5 to stretch upward, the scale 76 moves upward. At this time, the scale on the scale 76 that is flush with the top surface of the lower fixture 5 is the tensile length of the test sheet.

[0033] The working process of the present utility model is as follows:

[0034] First, fix the fixed bracket 61 on the outer wall of the fixed cylindrical frame 3, fixedly connect one side of the two transmission rods 66 to the left and right edges of the outer wall of the lever arm 4 respectively, and fixedly connect the other side of the two transmission rods 66 to the rotating bracket 63. After placing the test sheet at the clamping position of the fixture 5, start the motor 64 to drive the second straight gear 65 to rotate, thereby driving the first straight gear 62 and the rotating bracket 63 to rotate. At this time, the two transmission rods 66 drive the lever arm 4 to rotate, so that the fixture 5 clamps the sheet. After the test is completed, start the motor 64 to rotate in the reverse direction, drive the lever arm 4 to rotate and loosen the sheet. Before the tensile test of the sheet, rotate the knob 75 to make the second bevel gear 74 drive the first bevel gear 73 and the threaded rod 72 to rotate, thereby driving the connecting rod 71 to slide up and down along the threaded rod 72. The scale 76 is fixedly connected to the connecting rod 71. At this time, the scale 76 and the baffle 77 will move up and down together with the connecting rod 71. Adjust the scale 76 until the bottom surface of the baffle 77 fits the top surface of the lower fixture 5. At this time, the zero scale of the scale 76 is aligned with the top surface of the lower fixture 5. When the upper fixture 5 stretches upward, it drives the connecting rod 71 and the scale 76 to move upward. After the stretching is completed, the scale on the scale 76 that is aligned with the top surface of the lower fixture 5 is the length of the sheet stretch.
