Description

Technical Field

[0001] The present invention relates to the technical field of power hardware manufacturing, and particularly relates to a device for detecting the manufacturing strength of power hardware. Background Art

[0002] Power hardware is a key metal component used for connecting, fixing, and suspending conductors, insulators, and other electrical equipment in transmission lines. Its quality and performance are directly related to the safe and stable operation of the power system. As an important part of power hardware, the U-shaped hanging ring often bears tensile force, and it is particularly important to detect its tensile strength. Through detection, it can be ensured that the U-shaped hanging ring has sufficient tensile load-bearing capacity during actual operation, avoiding line failures or safety accidents caused by insufficient strength, and thus guaranteeing the reliability of power transmission.

[0003] The existing detection of the tensile strength of the U-shaped hanging ring of power hardware mainly relies on equipment such as tensile testing machines. Its basic principle is to fix the U-shaped hanging ring with a fixture, simulate the stress state in actual use, apply tensile force and measure the magnitude of the tensile force and the deformation of the hanging ring with the help of a sensor, so as to evaluate whether the tensile strength of the U-shaped hanging ring meets the standard.

[0004] However, in terms of multi-directional tensile strength detection, for the existing device for detecting the manufacturing strength of power hardware, the fixation of the fixtures of multiple groups of tensile connections to the U-shaped hanging ring requires operators to operate one by one. This process not only takes time and effort, reduces the detection efficiency, and is difficult to meet the batch detection requirements, but is also easily affected by subjective factors of manual operation, such as insecure fixation and operation errors, resulting in the accuracy and consistency of the detection data being difficult to guarantee, and unable to accurately reflect the true performance of the U-shaped hanging ring under multi-directional stress. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defect that the existing device for detecting the manufacturing strength of power hardware has low fixing efficiency of multiple groups of fixtures to the surface of the hanging ring.

The inclined surface of the driven plate 710 coincides with the inclined surface of the pressing plate 75, enhancing the stability of the workpiece during the detection process and preventing it from displacing or rotating due to force.

[0032] An adjusting structure 5 is provided on one side of the workbench 1. The adjusting structure 5 is used for moving and adjusting the positions of multiple clamping structures 4. The adjusting structure 5 includes a circular shell 51 installed on the top of the workbench 1. A motor 52 is provided inside the circular shell 51. The output end of the motor 52 is connected to a turntable 53. Three arc-shaped grooves 54 are equally spaced on the surface of the turntable 53. A circular block 55 is slidably connected in each arc-shaped groove 54. A cross-shaped plate 56 is also provided inside the circular shell 51. An L-shaped sliding plate 57 is slidable on the surface of the cross-shaped plate 56. The L-shaped sliding plate 57 is connected to the circular block 55 and is also connected to the clamping frame 41, facilitating the driving.

[0033] Specifically, it is a well-known and mature prior art for a workpiece to be fed into the workpiece area between two groups of long plates on the surface of the workbench 1 by an external feeding component or a robotic arm and other driving components, and the applicant will not describe it in detail here. Then, the staff operates the driving member 6 provided inside the workbench 1 through the operation screen. The driving member 6 can be a lead screw or any other bidirectional driving component. By starting the driving source of the driving member 6, the lead screws on both sides are each threadedly connected to the sleeves, and the two groups of sleeves are each slidably connected to the long rods. Thus, the two groups of sleeves drive the limiting structure 7 at the top of the moving block to move in the opposite direction to fix the workpiece in multiple directions, enabling the workpiece to be positioned in the detection area, effectively avoiding uneven stress during detection due to workpiece position deviation, greatly improving the accuracy and reliability of the subsequent multi-directional tensile strength detection results, and ensuring that the detection data truly reflects the performance of the workpiece;

[0034] As Figures 8-9 shown, as the two groups of moving blocks move in the opposite direction, they drive the vertical plate 71 to move closer to the workpiece, and the two groups of arc-shaped clamping plates 74 are inclined. When the workpiece enters between the two groups of arc-shaped clamping plates 74, it squeezes and moves the pressing plate 75. The pressing plate 75 is slidably connected to the T-shaped groove opened on the bottom surface of the cross plate 72 through the T-shaped block at the top. The cross plate 72 is connected to the vertical plate 71. Thus, the pressing plate 75 squeezes one end of the arc-shaped clamping plate 74, causing the two groups of arc-shaped clamping plates 74 to rotate in the opposite direction through the rotating rod 73 to be horizontal, and the two groups of arc-shaped clamping plates 74 clamp the surface of the workpiece. Since the inclined surface of the pressing plate 75 coincides with the inclined surface of the driven plate 710, when the pressing plate 75 moves towards the vertical plate 71, it squeezes the driven plate 710 downward, causing the driven plate 710 to drive the side block 78 at one end to slide downward in the vertical groove 77 opened on the surface of the side plate 76, and the side block 78 drives the spring 79 to stretch and store energy. The top of the side plate 76 is connected to the vertical plate 71. The downward movement of the driven plate 710 drives the lower pressing frame 711 at the bottom to move downward to limit the bolts of the workpiece, and the bottom end of the lower pressing frame 711 is magnetically fixed to the surface of the workbench 1, realizing automatic and tight clamping of the workpiece and bolt limiting. When the workpiece is placed, the arc-shaped clamping plates 74 can rotate and clamp adaptively to the shape of the workpiece, avoiding hard damage to the surface of the workpiece. At the same time, the limiting and magnetic fixing method of the lower pressing frame 711 for the bolts further enhances the stability of the workpiece during the detection process, preventing it from shifting or rotating due to stress and ensuring the smooth progress of the detection;

[0035] As Figures 3-4As shown, after the workpiece is fixed in an L-shaped position limit, the cross rail 2 is started through the operation screen. The cross rail 2 drives the detection component 3 to move. There are three groups of detection components 3, and the three groups of detection components 3 respectively perform tensile strength detection on three orientations of the workpiece. The detection component 3 is fixedly clamped on the surface of the workpiece in multiple groups through the clamping structure 4 connected to one side. The motor 52 is started through the operation screen. The motor 52 is fixed inside the circular shell 51, and the circular shell 51 is fixedly connected to the workbench 1. The motor 52 drives the turntable 53 at the output end to rotate. The rotation of the turntable 53 drives the three groups of arc grooves 54 on the surface to rotate, so that the round blocks 55 inside the three groups of arc grooves 54 slide from one end far from the center of the turntable 53 to the other end, so that the three groups of round blocks 55 respectively drive the L-shaped slide plates 57 on one side to slide in the cross plate 56. The three groups of L-shaped slide plates 57 respectively drive the clamping structures 4 at one end to approach the surface of the workpiece. By using the combination of the cross rail 2 and the motor drive, the movement of the detection component 3 can be accurately controlled, and multi-orientation positioning detection of the workpiece can be realized. The multiple groups of clamping structures 4 automatically approach the workpiece driven by components such as the motor, and can quickly and efficiently complete the clamping and fixing of multiple surfaces of the workpiece, improving the efficiency of the detection preparation work and laying a foundation for the smooth development of subsequent multi-orientation tensile detection;

[0036] As Figures 5-6As shown in the figure, as the three groups of L-shaped slide plates 57 drive the clamping structure 4 to contact the surface of the workpiece respectively, the workpiece first squeezes the second inclined plate 442 in contact to drive the second rotating rod 441 to rotate. The second inclined plate 442 rotates into the inside of the groove 42. The second rotating rod 441 is rotatably connected to the groove 42. The two ends of the second rotating rod 441 are provided with a second spring. The rotation of the second rotating rod 441 drives the second moving plate 443 to rotate close to the surface of the workpiece. Thus, the arc surface on the surface of the second moving plate 443 contacts the surface of the workpiece. At the same time, the workpiece squeezes and rotates the second linkage plate 445 rotatably connected in the notch 444 opened on the surface of the second moving plate 443. The rotation of the second linkage plate 445 presses the secondary pressure block 452 on the same side. The secondary pressure block 452 drives the rack 453 to be slidably connected to the notch 451. The rack 453 slides into the inside of the notch 451. Thus, the rack 453 moves to be meshed with the gear 454. The gear 454 drives the rotating plate 456 connected to the rotating block 455 to rotate. Thus, the rotating plate 456 drives the nail head 461 to rotate 90 degrees. As the second inclined plate 442 is squeezed and rotated, the second inclined plate 442 squeezes the first inclined plate 432 to drive the first rotating rod 431 to rotate. The first inclined plate 432 rotates into the inside of the groove 42. The first rotating rod 431 is rotatably connected to the groove 42. The two ends of the first inclined plate 432 are provided with a first spring. The first rotating rod 431 drives the first moving plate 433 to rotate close to the surface of the workpiece, making the arc surface on the surface of the first moving plate 433 contact the surface of the workpiece. At the same time, the workpiece squeezes and rotates the first linkage plate 435 rotatably connected in the notch 434 opened on the surface of the first moving plate 433. The rotation of the first linkage plate 435 presses the secondary pressure block 452 on the same side. The secondary pressure block 452 drives the rack 453 to be slidably connected to the notch 451. The rack 453 slides into the inside of the notch 451. Thus, the rack 453 moves to be meshed with the gear 454. The gear 454 drives the rotating plate 456 connected to the rotating block 455 to rotate. Thus, the rotating plate 456 drives the locking component 46 except the nail head 461 to rotate 90 degrees. Furthermore, the opening opened on the surface of the fixed shell 462 corresponds to the nail head 461. The nail head 461 is inserted into the inside of the inner shell 463 inside the fixed shell 462. Thus, the nail head 461 squeezes and rolls the steel balls 465 inside the inclined groove 464 opened on the surface of the inner shell 463. The steel balls 465 contact and roll inside the outer shell 466. Since the outer shell 466 is arranged outside the inclined groove 464, and the inclined groove 464 and the outer shell 466 are frustum-shaped, and multiple groups of steel balls 465 are pushed by the nail head 461 to roll to the large-diameter end of the inclined groove 464, the distance between multiple groups of steel balls 465 increases, making the nail head 461 inserted and clamped. The compression spring 467 is compressed and stores energy. The three groups of clamping structures 4 move simultaneously to be clamped and fixed with multiple surfaces of the workpiece. The arrangement of the nail head 461 of the locking component 46 and multiple groups of steel balls 465 makes the direction of the pulling force reverse when the workpiece is subjected to the tensile strength test by the detection component 3. The greater the pulling force, the greater the locking effect of the locking component 46, avoiding the problem of falling off when the workpiece is subjected to the tensile test.Moreover, start the cross guide rail 2 to drive the corresponding detection component 3 to move in the opposite direction to the workpiece, so that the three groups of detection components 3 perform the tensile strength detection work of the maximum value on multiple orientations of the workpiece. Therefore, the workpiece will be pulled until it breaks, and the maximum value is measured. The multiple linkage design of the clamping structure 4 makes the clamping process more conform to the shape of the workpiece, enhancing the firmness of clamping. The locking component 46 uses ingenious structures such as the inclined groove 464 and the steel ball 465 to achieve the function of automatically enhancing the locking effect as the pulling force increases, effectively avoiding the workpiece falling off during the detection process, ensuring the integrity and accuracy of the detection data. By driving the detection component 3 to move in the opposite direction to the workpiece through the cross guide rail 2 for multi-directional tensile strength detection, the maximum tensile strength of the workpiece in different directions can be comprehensively and accurately obtained, providing rich and reliable data for evaluating the performance of the workpiece;

[0037] When it is necessary to unlock the locking component 46, the electric push rod 469 provided on the surface of the fixed shell 462 can be started through the operation screen, so that the electric push rod 469 drives the push plate 468 connected to the output end to move away from the compression spring 467. Since a plate groove is provided on the surface of the fixed shell 462 corresponding to the push plate 468, the electric push rod 469 drives the push plate 468 to slide in the plate groove, and the push plate 468 drives the inner shell 463 to move away from the compression spring 467, so that the distance between the steel balls 465 rollingly connected inside the inner shell 463 is enlarged. Thus, the distance between multiple groups of steel balls 465 is greater than the diameter of the nail head 461, so that it is convenient for the nail head 461 to disengage from the fixed shell 462. Through the remote control of the electric push rod 469, the unlocking of the locking component 46 can be quickly realized, improving the use convenience and working efficiency of the detection equipment. After the detection is completed, the workpiece can be taken out in time and easily, facilitating the connection of the subsequent detection process and reducing the idle time of the equipment.
