[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0023] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0024] Example 1: See Figure 1-Figure 3 The present invention provides a technical solution: an electric power fitting connection performance detection device, comprising a support frame 1, a support leg 2 fixedly connected to the bottom outer wall of the support frame 1, a first hydraulic rod 4 fixedly connected to the inner wall of the support frame 1, a first fixed shaft 3 fixedly connected to the outer surface of the support frame 1, and further comprising: The adjusting mechanism 5 includes a first fixed frame 501 fixedly connected to the output end of the first hydraulic rod 4, an auxiliary mechanism 6 is provided on the outside of the first fixed frame 501, a sliding groove 502 is provided on the outer surface of the first fixed frame 501, a dual-axis motor 506 is fixedly connected to the bottom outer wall of the first fixed frame 501, the output end of the dual-axis motor 506 is fixedly connected to the first rotating frame 507, the inner wall of the end of the first rotating frame 507 away from the dual-axis motor 506 is fixedly connected to the second hydraulic rod 508, the output end of the second hydraulic rod 508 passes through the first rotating frame 507 and is fixedly connected to the connecting frame 509, the inner wall of the end of the connecting frame 509 away from the first rotating frame 507 is fixedly connected to the vibrator 510, the dual-axis motor 506 drives the first rotating frame 507 to rotate around the fixed point, so that it moves to the electric metal The tool is flipped on one side. When conducting mechanical performance testing on the power fitting, after firmly clamping both ends of the power fitting with the clamping assembly 606, the first hydraulic rod 4 is started. The first hydraulic rod 4 pushes the first fixing frame 501 to which its output end is fixed, thereby applying tension to both ends of the power fitting. The tension test is carried out in the state where the power fitting clamps and fixes the cable. The dual-axis motor 506 drives the first rotating frame 507, so that the first rotating frame 507 drives the second hydraulic rod 508 to flip toward the side of the power fitting. The second hydraulic rod 508 pushes the connecting frame 509 to which its output end is fixed, causing it to move toward the side of the power fitting. The vibrator 510 fixedly connected inside the connecting frame 509 will simulate the vibration of the power fitting in a taut state, thereby testing the performance of the power fitting under extreme conditions.

[0025] The outer wall of the first fixed frame 501 is rotatably connected to the first rotating rod 503 through a rotating shaft, and the end of the first rotating rod 503 away from the first fixed frame 501 is rotatably connected to the first sliding block 504 through a rotating shaft. The first sliding block 504 is slidably connected to the outer surface of the first fixed shaft 3, and the outer wall of the first sliding block 504 away from the first rotating rod 503 is fixedly connected to the first elastic component 505. The end of the first elastic component 505 away from the first sliding block 504 is fixedly connected to the first fixed shaft 3, and the first fixed shaft 3 has an effect on the sliding distance of the first sliding block 504. When the first hydraulic rod 4 pushes the first fixed frame 501 to move, the first fixed frame 501 drives the first rotating rod 503 to pull the first sliding block 504 to slide on the outer surface of the first fixed shaft 3, and at the same time stretches the first elastic component 505. The first sliding block 504 ensures that the sliding distance of the first fixed frame 501 on both sides thereof is equal through the coordinated action with the first rotating rod 503. Therefore, when the electrical hardware is subjected to a tensile test, the tensile force on both sides of the electrical hardware can be ensured to be consistent, thereby effectively avoiding deviations in the test data and ensuring the accuracy of the test results.

[0026] Example 2: Please refer to Figure 4-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary mechanism 6 includes a sliding frame 601 slidably connected to the first fixed frame 501, the outer surface of the sliding frame 601 is fixedly connected to the auxiliary motor 602, the output end of the auxiliary motor 602 passes through the sliding frame 601 and is fixedly connected to the auxiliary wheel 603, the auxiliary wheel 603 is slidably connected to the inner wall of the sliding groove 502, the outer wall of the sliding frame 601 is fixedly connected to the second fixed frame 604, the inner wall of the second fixed frame 604 is fixedly connected to the third hydraulic rod 605, the output end of the third hydraulic rod 605 is provided with a clamping assembly 606, the clamping assembly Component 606 includes a first clamping rod 6061 fixedly connected to the third hydraulic rod 605. The third hydraulic rod 605 adjusts the distance between the first clamping rod 6061 and the power fitting through telescopic movement. After the clamping component 606 completes the clamping and fixing of the two ends of the power fitting, the auxiliary motor 602 drives the auxiliary wheel 603 to roll in the sliding groove 502. As the auxiliary wheel 603 rolls, the sliding frames 601 located on both sides of the first hydraulic rod 4 will slide in opposite directions along the outer surface of the first fixed frame 501, thereby applying torque to the power fitting, thereby realizing torque testing of the power fitting.

[0027] The bottom outer wall of the first clamping rod 6061 is rotatably connected to the second rotating rod 6065 through a rotating shaft. The end of the second rotating rod 6065 away from the first clamping rod 6061 is rotatably connected to the second rotating frame 6066 through a rotating shaft. The end of the second rotating frame 6066 away from the second rotating rod 6065 is rotatably connected to the second fixed frame 604. The first clamping rod 6061 drives the second rotating frame 6066 to rotate around the fixed point through the second rotating rod 6065, so that the second rotating frame 6066 can flip at an angle. The bottom outer wall of the first clamping rod 6061 is fixedly connected to the second fixed axis 6062. The end of the second rotating frame 6066 away from the second fixed frame 604 is rotatably connected to the second clamping rod 6067 through a rotating shaft. The outer wall of the second clamping rod 6067 on one side close to the second rotating frame 6066 is fixedly connected to a spring 6068. The spring 6068 is fixedly connected to the outer wall of the second clamping rod 6067 on the other side. 68, one end away from the second clamping rod 6067 is fixedly connected to the second rotating frame 6066. The spring 6068 elastically resets the second clamping rod 6067 to its initial position after rotation. The third hydraulic rod 605 pulls the first clamping rod 6061. After the first clamping rod 6061 is subjected to force, it drives the second rotating rod 6065 to pull the second rotating frame 6066 rotatably connected to the second fixed frame 604. The second clamping rod 6067 rotatably connected to the top of the second rotating frame 6066 then clamps and fixes the power fitting. When the second clamping rod 6067 contacts the outer surface of the power fitting, the second clamping rod 6067 will squeeze the spring 6068. Through the compression deformation of the spring 6068, the clamping angle of the second clamping rod 6067 can be adjusted, so that it can better fit the outer surface of the power fitting, ensuring a firm clamping and a high degree of fit.

[0028] The end of the second fixed shaft 6062 away from the first clamping rod 6061 passes through the second fixed frame 604 and is fixedly connected to the limiting block 6064. The limiting block 6064 is slidably connected to the outer surface of the third hydraulic rod 605. The top outer wall of the limiting block 6064 is fixedly connected with a second elastic component 6063. The end of the second elastic component 6063 away from the limiting block 6064 is fixedly connected to the second fixed frame 604. When the third hydraulic rod 605 drives the first clamping rod 6061 to slide, the second fixed shaft 6062 improves the stability of the first clamping rod 6061 during sliding. Through the elasticity of the second elastic component 6063 itself, the vibration generated by the first clamping rod 6061 during the movement is effectively absorbed, thereby enhancing the stability of the first clamping rod 6061 driven by the third hydraulic rod 605, thereby ensuring the smooth progress of the entire clamping operation.
