Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0027] refer to Figure 1-6 A machine body base plate 1 is set, and a protective railing 11 is set on the machine body base plate 1. The protective railing 11 can protect the insulator from damage caused by external forces in the environment during the processing. A clamping assembly 2 is slidably connected on the machine body base plate 1. The clamping assembly 2 is also set at the bottom of the top plate of the upper end of the protective railing 11, realizing the effect of clamping the insulator from both the top and bottom. The two clamping assemblies 2 are arranged facing each other, and the insulator is placed between the two clamping assemblies 2.

[0028] refer to Figure 1-6The clamping assembly 2 includes a clamping base plate 21, on which clamping blocks 22 are arranged in a circular array. The clamping blocks 22 can move and clamp the surface of the insulator to be tested, applying force against the surface of the insulator. Elastic grooves 211 are formed around the perimeter of the clamping base plate 21. A clamping spring 212, fixedly connected to the clamping blocks 22, is fixedly connected within the elastic grooves 211. The elastic force of the clamping spring 212 is away from the center of the clamping base plate 21. The clamping spring 212 applies a continuous force away from the center of the clamping base plate 21 to the clamping blocks 22, ensuring that the clamping blocks 22 are in an open state in their natural state. An abutment groove 221 is formed on the clamping blocks 22, into which the clamping spring 212 extends and abuts against the surface. The inner wall of the groove 221 is fixedly connected to limit the clamping spring 212. The center of the clamping base plate 21 is provided with a drive groove 23. The side wall of the drive groove 23 is provided with a linkage groove 231. A linkage rod 232 is slidably connected in the linkage groove 231. The linkage rod 232 and the clamping block 22 are rotatably connected. The center of the drive groove 23 is rotatably connected with a drive rotating block 24 that drives the linkage rod 232 to move along the length of the linkage groove 231. By rotating the drive rotating block 24, the linkage rod 232 is driven to slide in the linkage groove 231. Thus, through the rotational connection between the linkage groove 231 and the clamping block 22, the clamping block 22 is driven to rotate around the bearing center at the rotational connection, thereby achieving the effect of driving the surface of the clamping block 22 to move toward or away from the surface of the insulator.

[0029] refer to Figure 1-6 The drive block 24 is divided into a rotating protrusion 241 and a rotating part 242. The rotating protrusion 241 abuts against the end of the linkage rod 232. When the rotating protrusion 241 and the end of the linkage rod 232 abut, the clamping block 22 applies a clamping force to the surface of the insulator. When there is no abutment, the clamping block 22 opens and moves away from the surface of the insulator under the action of elastic force. Hinges 25 are fixedly connected around the clamping base plate 21. The clamping block 22 and the hinges 25 are rotatably connected. The rotating protrusion 241 includes a protruding guide surface 243, which can... Regarding the rotation and reset of the linkage rod 232, the extension height of the rotating protrusion 241 is greater than that of the rotating part 242. When the drive block 24 rotates, the end of the linkage rod 232 will switch from the rotating protrusion 241 to the rotating part 242 to achieve the switching of the contact mode of the end of the linkage rod 232. A rotating connecting block 244 is fixedly connected to the drive block 24, and a rotating handle 245 is fixedly connected to the side wall of the rotating connecting block 244. By driving the rotating handle 245, the clamping effect of the clamping component 2 can be achieved by manually controlling it.

[0030] refer to Figure 1-6A clamping drive plate 26 is fixedly connected to the top of the clamping base plate 21, and a lead screw motor 12 is fixedly connected to the top of the guardrail 11. A rotating lead screw is fixedly connected to the output end of the lead screw motor 12. When the lead screw motor 12 rotates, it drives the slider on the rotating lead screw to slide. A slide plate 13 is fixedly connected to the end of the rotating lead screw, and the slider drives the slide plate 13 to move, thereby driving the slide plate 13 to slide through the lead screw motor 12. Slide rails 14 are fixedly connected to both sides of the inner cavity of the guardrail 11. The slide plate 13 and the slide rails 14 are slidably connected, restricting the slide plate 13. The sliding direction of 3 maintains the stability of the sliding of the slide plate 13. The slide plate 13 and the clamping drive plate 26 are fixedly connected. A horizontal rail 15 is fixedly connected to the machine body base plate 1. A support plate 151 is slidably connected to the horizontal rail 15. The clamping component 2 located at the bottom is fixedly connected to the surface of the support plate 151. A horizontal propulsion cylinder 152 is fixedly connected to the outside of the guardrail 11. The piston rod end of the horizontal propulsion cylinder 152 is fixedly connected to one side of the support plate 151. The position of the bottom clamping component 2 can be adjusted by the horizontal propulsion cylinder 152.

[0031] The working principle of this device is as follows: When performing tensile testing on an insulator, the insulator is placed inside the protective barrier 11. At this time, the horizontal propulsion cylinder 152 is activated to adjust the position of the bottom clamping assembly 2, assembling the bottom of the insulator and the bottom clamping assembly 2. Rotating the rotating handle 245 of the bottom clamping assembly 2 will drive the drive rotating block 24 to rotate. The drive rotating block 24 will rotate the rotating protrusion 241 to the position corresponding to the end of the linkage rod 232 and push the linkage rod 232 away from the center of the drive groove 23. When the linkage rod 232 moves, the clamping block 22 will rotate towards the surface of the insulator with the rotating shaft at the other end of the linkage rod 232 as the center, and abut against the surface of the insulator. At this time, the bottom clamping assembly 2 will clamp the insulator. The bottom of the insulator is clamped and fixed. Then, the screw motor 12 is started, causing the slide plate 13 to slide along the slide rail 14. The position of the top clamping component 2 is adjusted according to the height of the insulator. The same driving operation is performed as the bottom clamping component 2. The rotating handle 245 of the top clamping component 2 is pulled, so that the top clamping component 2 abuts against the top of the insulator, thereby fixing the insulator. At this time, the tensile strength test of the insulator can be performed. By driving the screw motor 12 in reverse, the top clamping component 2 is driven to move upward, while the bottom clamping component 2 fixes the bottom of the insulator, so that the surface of the insulator is subjected to tension, thereby realizing the tensile strength test process. This completes the effect of more stable clamping and fixing of the insulator and mechanical testing.

[0032] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
