[0026] 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 the embodiments.

[0027] Embodiment: This embodiment discloses a high-strength copper rod bending resistance testing device, which is suitable for testing copper rods with a diameter of less than 15 mm. Figure 1-Figure 8 As shown, the present invention comprises: a machine base 1; a fixed platform 3, which is fixedly connected to the machine base 1, and clamping components 4 are connected at both ends of the fixed platform 3 for clamping and fixing the copper rod. After the copper rod is clamped and fixed, the copper rod is located at the center of the annular seat 21; a testing mechanism 2, which comprises an annular seat 21, and the annular seat 21 is fixedly connected to the machine base 1. A testing component 22 capable of moving along its circumferential direction is connected to the annular seat 21. When the testing component 22 moves to different positions of the annular seat 21, it can perform bending tests on the copper rod in different directions, with various testing methods and more accurate test results; a driving mechanism 5, which is fixedly installed on the fixed platform 3, and is used to drive the testing component 22 to perform bending tests on the copper rod.

[0028] like Figure 3-Figure 4 As shown, the test assembly 22 includes a slide seat 221, and the slide seat 221 can slide circumferentially along the annular seat 21. The surface of the annular seat 21 is fixedly connected with an annular slide rail 25, and the inner side of the annular slide rail 25 is fixedly connected with a gear ring 26. The slide seat 221 is fixedly connected with a guide seat 225, and the guide seat 225 is movably connected with a pressure column 224, and the pressure column 224 faces the center direction of the annular seat 21. One end of the pressure column 224 is fixedly connected with a pressure block 228. During testing, the pressure block 228 contacts the copper rod, and the pressure block 228 is in an arc shape; the slide seat 221 is rotatably connected with a gear 222 that meshes with the gear ring 26. When the gear 222 rotates, it can drive the test assembly 22 to slide along the annular slide rail 25. The gear 222 is coaxially connected with The rotating part 223 and the pressure column 224 are connected with a rack 227 that cooperates with the rotating part 223; when the pressure column 224 moves toward the direction close to the copper rod, the rack 227 will not drive the gear 222 to rotate through the rotating part 223; when the pressure column 224 has finished testing the copper rod, when the pressure column 224 moves away from the copper rod, the rack 227 can drive the gear 222 to rotate through the rotating part 223, thereby driving the test assembly 22 to slide once on the annular seat 21 and changing the position of the test assembly 22; thereby, the pressure column 224 performs a bending test on the copper rod once, drives the gear 222 to rotate once, drives the test assembly 22 to move once on the annular seat 21, and then can continuously perform bending tests on the copper rod in different directions.

[0029] Preferably, the pressure column 224 is fixedly connected to a fixed block 229, the fixed block 229 is slidably connected to a slider 2210, the slider 2210 is fixedly connected to a bracket 2212, the rack 227 is fixedly connected to the bracket 2212, and the fixed block 229 is rotatably connected to a screw 2211, and the screw 2211 is threadedly connected to the slider 2210; the position of the rack 227 can be adjusted by the screw 2211, thereby controlling the meshing of the rack 227 and the rotating member 223; when the rack 227 and the rotating member 223 can mesh, the pressure column 224 performs a bending test on each pair of copper rods once, which can drive the gear 222 to rotate once, and drive the test assembly 22 to move once on the annular seat 21; when the rack 227 and the rotating member 223 cannot mesh, the pressure column 224 performs a bending test on each pair of copper rods once, and will not drive the test assembly 22 to move. At this time, the copper rods are continuously bent in one direction.

[0030] like Figure 5 As shown, the rotating member 223 includes an outer gear ring 2231, and a ratchet 2232 is rotatably connected inside the outer gear ring 2231. The ratchet 2232 is coaxially and fixedly connected to the gear 222. When the ratchet 2232 rotates, it can drive the gear 222 to rotate together. A plurality of ratchet pawls 2233 cooperating with the ratchet 2232 are connected to the inner wall of the outer gear ring 2231, and an elastic member 2234 is connected between the ratchet pawls 2233 and the inner wall of the outer gear ring 2231; when the outer gear ring 2231 rotates forward, it can drive the ratchet 2232 to rotate, and then drive the gear 222 to rotate; when the outer gear ring 2231 rotates reversely, it will not drive the ratchet 2232 and the gear 222 to rotate.

[0031] like Figure 6 As shown, the test assembly 22 also includes a fixed frame 23, which is fixedly connected to the machine base 1, and a guide rail 231 is fixedly connected to the fixed frame 23. A ring-shaped movable seat 24 is slidably connected to the guide rail 231, and a rotating seat 241 is rotatably connected to the surface of the movable seat 24. One end of the pressure column 224 is fixedly connected to a hinge block 226, and a first push rod 27 is hinged between the hinge block 226 and the rotating seat 241. When the movable seat 24 slides on the guide rail 231, it drives the pressure column 224 to move, thereby controlling the pressure column 224 to perform a bending test on the copper rod, and when the test assembly 22 slides on the annular slide rail 25, it drives the rotating seat 241 to rotate on the surface of the movable seat 24, thereby cooperating with the bending test of the copper rod in different directions.

[0032] like Figure 7-Figure 8As shown, the clamping assembly 4 includes a support arm 41, a slide groove 32 slidably connected to the support arm 41 is provided on the fixed platform 3, a screw rod 31 is rotatably connected in the slide groove 32, the screw rod 31 is threadedly connected to the support arm 41, and the distance between the two clamping assemblies 4 can be adjusted by rotating the screw rod 31; a connecting seat 42 is slidably connected to the end face of the support arm 41, and a groove 47 slidably connected to the connecting seat 42 is provided on the end face of the support arm 41, and a spring 48 is fixedly connected between the connecting seat 42 and the groove 47; when the copper rod is bent, the connecting seat 42 will slide in the groove 47; a clamping seat 43 is rotatably connected to the connecting seat 42, and a through hole 44 matching the copper rod is provided on the clamping seat 43, and a clamping block 45 is connected in the through hole 44 for clamping and fixing the copper rod, a locking bolt 46 is threadedly connected to the clamping seat 43, and one end of the locking bolt 46 is rotatably connected to the clamping block 45; the clamping block 45 is driven to clamp and fix the copper rod by rotating the locking bolt 46.

[0033] Preferably, a spring frame 49 is fixedly connected above the connecting seat 42 , and a tension spring 410 is fixedly connected between the spring frame 49 and the clamping seat 43 . The tension spring 410 applies tension to the connecting seat 42 to reset the connecting seat 42 .

[0034] Preferably, the driving mechanism 5 includes: a frame 51, a hydraulic cylinder 52 is installed on the frame 51, a lifting seat 53 is fixedly connected to the piston of the hydraulic cylinder 52, and a guide column movably connected to the lifting seat 53 is fixedly connected to the frame 51, and a second push rod 54 is hinged between the lifting seat 53 and the movable seat 24; the lifting seat 53 is driven to descend by the hydraulic cylinder 52, which will drive the movable seat 24 to slide on the guide rail 231, and drive the pressure column 224 to perform a bending test on the copper rod.

[0035] Working principle: During the test, the copper rod is clamped and fixed on the two clamping components 4, and the movable seat 24 is driven to move by the driving mechanism 5, thereby driving the pressure column 224 to perform a bending test on the copper rod. After each test, the pressure column 224 drives the test component 22 to slide once on the annular seat 21 during its return process, thereby changing the position of the test component 22 on the annular seat 21, thereby being able to continuously perform bending tests on the copper rod in different directions; when it is necessary to perform a unidirectional bending test on the copper rod, the position of the rack 227 can be adjusted by the screw 2211 so that the rack 227 cannot engage with the rotating part 223. At this time, after each bending test on the copper rod by the pressure column 224, the position of the test component 22 remains unchanged, thereby being able to perform a unidirectional bending test on the copper rod.
