Description

Technical Field

[0001] This utility model relates to the field of wire testing technology, specifically a wire tensile strength testing device. Background Technology

[0002] To ensure reliable installation and use of electrical wires, tensile testing is required before the wires leave the factory. Currently, universal testing machines are commonly used to perform tensile testing on electrical wires. During the tensile testing process, the elongation of the wire also needs to be measured, which is usually estimated based on the changes in the positions of the two clamps.

[0003] According to a public announcement of a wire tensile strength testing device (announcement number: CN217505493U), the above application includes a base and a controller. The base is provided with a fixed seat and a linear movement mechanism. A tensile sensor is installed on the fixed seat. The tensile sensor and the linear movement mechanism are both electrically connected to the controller. Wire clamps are installed on the sensitive beam of the tensile sensor and the moving end of the linear movement mechanism.

[0004] However, in actual use, the above-mentioned testing device requires manual winding of the wire onto the spool. This requires careful winding of the wire one turn at a time to avoid misalignment, otherwise the wire distribution may be asymmetrical, affecting the accuracy of the test data. In view of this, we propose a wire tensile strength testing device. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the tensile strength of electrical wires, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire tensile strength testing device, comprising a frame, a controller fixedly connected to the top end face of the frame, a scale fixedly connected to the side wall of the frame, a stretching assembly provided on the top end face of the frame, and a winding assembly provided on the top of the stretching assembly, the winding assembly comprising: Mounting bracket, wherein a limit ring is fixedly connected to the side wall of the mounting bracket, and a through groove is provided on the side wall of the mounting bracket; A rotating shaft, a winding shaft is fixedly connected to the side wall of the rotating shaft, a gear is fixedly connected to the side wall of the rotating shaft, a slot is opened in the side wall of the rotating shaft, the slot is inserted into a plug, and a handle is fixedly connected to the end face of the plug. The placement block has a guide groove on its top and a toothed rod fixedly connected to its side wall.

[0007] Preferably, the stretching assembly includes a drive motor, which is fixedly connected to the side wall of the frame. The output end of the drive motor is fixedly connected to a lead screw, and the side wall of the lead screw is connected to a movable frame. The top end face of the movable frame is fixedly connected to the mounting frame.

[0008] Preferably, a tension sensor is fixedly connected to the side wall of the frame, and the end face of the tension sensor is fixedly connected to the mounting bracket. The tension sensor is used to detect the maximum tension that the wire body can withstand.

[0009] Preferably, the rotating shaft is rotatably connected to the mounting bracket, the side wall of the winding shaft is wound with the wire body, and the handle is inserted into the limiting ring.

[0010] Preferably, the cross-section of the placement block is trapezoidal, the rack meshes with the gear, the placement block is inserted into the through slot, and the rotation of the gear drives the rack to move laterally.

[0011] Preferably, a crossbar is fixedly connected to the side wall of the frame, and the crossbar is movably connected to the movable frame. The restriction of the crossbar allows the movable frame to move only laterally.

[0012] Preferably, a limiting frame is fixedly connected to the inner wall of the mounting bracket, and the limiting frame is slidably connected to the placement block.

[0013] Compared with the prior art, the present invention provides a device for testing the tensile strength of electrical wires, which has the following advantages: 1. This wire tensile strength testing device, through its winding assembly, utilizes the friction between the wire bodies to prevent them from being pulled out. The layered winding creates significant friction, making it difficult for the wire body to slide or loosen on its own without unwinding. This stable winding state helps maintain the stability of the wire body during testing, improving the consistency of the test. The guide groove limits the movement trajectory of the wire body, ensuring that each turn of the wire body is precisely aligned in the predetermined position, avoiding misalignment, overlap, and other problems, thus improving the accuracy of the test. The wire body can be installed by turning the handle. Compared to traditional manual winding, this device makes the wire body arrangement more neat and standardized, improving winding consistency and repeatability, which is conducive to standardized operation. It is particularly suitable for batch testing and electrical performance consistency comparison.

[0014] 2. The wire tensile strength testing device, through the set limit frame, provides a fixed sliding direction and range for the placement block, to prevent the placement block from shaking, shifting or rotating during the movement, and to keep its movement trajectory linear, stable and controllable, so as to ensure the accurate wiring of the wire body.

[0017] like Figures 1-5 As shown, this utility model provides a technical solution: a wire tensile strength testing device, including a frame 1, a controller 2 fixedly connected to the top end face of the frame 1, a scale 3 fixedly connected to the side wall of the frame 1, a stretching component 4 provided on the top end face of the frame 1, a winding component 5 provided on the top of the stretching component 4, and the winding component 5 including a mounting bracket 501, a limiting ring 502, a through groove 503, a rotating shaft 504, a winding shaft 505, a gear 506, a slot 507, a plug 508, a handle 509, a placement block 510, a guide groove 511, and a toothed bar 512.

[0018] In one embodiment of the present invention, a limiting ring 502 is fixedly connected to the side wall of the mounting bracket 501, and a through groove 503 is provided on the side wall of the mounting bracket 501.

[0019] The rotating shaft 504 is rotatably connected to the mounting bracket 501. A winding shaft 505 is fixedly connected to the side wall of the rotating shaft 504. The wire body 7 is wound around the side wall of the winding shaft 505. A gear 506 is fixedly connected to the side wall of the rotating shaft 504. A slot 507 is opened on the side wall of the rotating shaft 504. The slot 507 is inserted into the plug 508. A handle 509 is fixedly connected to the end face of the plug 508. The handle 509 is inserted into the limit ring 502.

[0020] The placement block 510 is inserted into the through groove 503. The cross-section of the placement block 510 is trapezoidal. A guide groove 511 is provided on the top of the placement block 510. A toothed rod 512 is fixedly connected to the side wall of the placement block 510. The toothed rod 512 meshes with the gear 506. The rotation of the gear 506 drives the toothed rod 512 to move laterally.

[0021] The stretching assembly 4 includes a drive motor 401, which is fixedly connected to the side wall of the frame 1. The output end of the drive motor 401 is fixedly connected to a lead screw 402. The side wall of the lead screw 402 is connected to a movable frame 403. The top end face of the movable frame 403 is fixedly connected to the mounting frame 501. A tension sensor 404 is fixedly connected to the side wall of the frame 1. The end face of the tension sensor 404 is fixedly connected to the mounting frame 501. The tension sensor 404 is used to detect the maximum tension that the wire body 7 can withstand. A crossbar 8 is fixedly connected to the side wall of the frame 1. The crossbar 8 is movably connected to the movable frame 403. The restriction of the crossbar 8 allows the movable frame 403 to move only laterally.

[0022] Place the wire body 7 into the guide groove 511, pull out the handle 509 to disconnect it from the limit ring 502. Then rotate the handle 509 to rotate the winding shaft 505, winding the wire body 7 around the side wall of the winding shaft 505. The rotation of the winding shaft 505 pulls the gear 506 to rotate, further driving the rack 512 and the placement block 510 to move laterally. This guides the wire body 7 to reciprocate on the winding shaft 505, causing the outer layer of the wire body 7 to press against the lower layer, as per the instruction manual. Figure 4 As shown, then insert handle 509 so that handle 509 is connected to limit ring 502. At this time, pull the wire body 7, but due to the friction between the wire bodies 7, the wire body 7 cannot be pulled out. The layered winding causes greater friction, and the wire body 7 is difficult to slide or loosen on its own without unwinding. The stable winding state is conducive to maintaining the stability of the wire body 7 during testing and improving the consistency of the test.

[0023] Meanwhile, the guide groove 511 limits the movement trajectory of the wire body 7, so that each turn of the wire body 7 can be precisely arranged in the predetermined position, avoiding misalignment, overlap and other problems, and improving the accuracy of the test. By turning the handle 509, the wire body 7 can be installed. Compared with the traditional manual winding, the wire body 7 is arranged more neatly and standardized, improving the winding consistency and repeatability, which is conducive to standardized operation. It is especially suitable for batch testing, electrical performance consistency comparison and other occasions.

[0024] In addition, the inner wall of the mounting bracket 501 is fixedly connected to the limiting bracket 6, which is slidably connected to the placement block 510. The limiting bracket 6 acts as a guide rail, providing a fixed sliding direction and range for the placement block 510, preventing the placement block 510 from shaking, shifting or rotating during movement, maintaining its linear, stable and controllable movement trajectory, ensuring that the wire body 7 is accurately laid out and neatly aligned, and avoiding tangling and misalignment.

[0025] In this invention, during use, the wire body 7 is placed in the guide groove 511, and the handle 509 is pulled out, thus disengaging the handle 509 from the limiting ring 502. The handle 509 can then be rotated, causing the winding shaft 505 to rotate, winding the wire body 7 around the side wall of the winding shaft 505. The rotation of the winding shaft 505 pulls the gear 506 to rotate, further driving the rack 512 and the placement block 510 to move laterally. This guides the wire body 7 to be repeatedly wound around the winding shaft 505, causing the outer layer of the wire body 7 to press against the lower layer, as shown in the attached instruction manual. Figure 4 As shown, insert the handle 509 so that it engages with the limiting ring 502. The guide groove 511 limits the movement trajectory of the wire body 7, so that each loop of the wire body 7 can be precisely arranged in the predetermined position, avoiding misalignment, overlap and other problems, and improving the accuracy of detection. By rotating the handle 509, the wire body 7 can be installed.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
