Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a device for testing the bending resistance of electronic wires. Background Technology

[0002] Existing electronic wire bending resistance testing devices can fix electronic wires of different sizes and move one end of the wire back and forth to repeatedly bend it until it breaks. This effectively tests the bending resistance of electronic wires. However, during the initial bending process, the bending point and direction of the electronic wire are not fixed, resulting in multiple bending points and affecting the test results. For example, a cable bending resistance testing device disclosed in Chinese Patent No. CN202420609444.4, although it can use an electromagnetic relay connected to the power supply to generate a magnetic field through the coil of the internal electromagnet to apply an attraction force to the armature, causing the armature to connect to the moving contact and supply power to the motor, controller, and electric push rod, and stop the power supply when the cable breaks and sound an alarm to alert the outside world, this design does not require personnel to be constantly on the side, freeing up manpower and improving work efficiency. However, it does not determine the bending position and direction of the cable during the bending process, which may result in multiple bending points in the initial bending process, thus affecting the test results and limiting its use. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a device for testing the bending resistance of electronic wires. This device uses a double-headed screw to drive a lower limiting plate that limits the bending according to the diameter of the electronic wire, ensuring that the electronic wire can only bend upwards during the bending process. At the beginning of the bending, a sliding plate and the limiting plate restrict the bending of the electronic wire from the middle. During the bending process, an electric telescopic rod drives the device to keep the limiting plate always positioned on both sides of the electronic wire, preventing the bending position and direction from varying and affecting the testing results. Furthermore, a motor drives the shaft cylinder to rotate, allowing the screw to drive a fixing plate to fix electronic wires of different diameters, improving the fixing effect.

[0004] This utility model also provides an electronic wire bending resistance testing device, comprising: a base plate, a second bending plate fixedly connected to the upper surface of the base plate, a first bending plate slidably connected to the upper surface of the base plate, a first motor fixedly connected to the upper surfaces of both the first and second bending plates, a first fixing plate fixedly connected to the inner side walls of both the first and second bending plates, a shaft cylinder fixedly connected to the output end of the first motor, a screw threadedly connected to the inner side wall of the shaft cylinder, and a second fixing plate fixedly connected to the end of the screw away from the shaft cylinder;

[0005] An electric telescopic rod is fixedly connected to the side surface of the bending plate one. A sliding plate is fixedly connected to the output end of the electric telescopic rod one. An electric telescopic rod two is fixedly connected to the upper surface of the sliding plate. A sliding groove plate is fixedly connected to the output end of the electric telescopic rod two. A motor three is fixedly connected to the side surface of the sliding groove plate. A double-ended screw is fixedly connected to the output end of the motor three. A limiting plate is threadedly connected to the side surface of the double-ended screw. Through these components, the limiting plate causes the electronic wire to bend upwards from the middle position, avoiding the impact of different bending directions and bending points on the detection effect.

[0006] According to the present invention, an electronic wire bending resistance testing device is provided, wherein a second motor is fixedly connected to the side surface of the base plate, and a threaded rod is fixedly connected to the output end of the second motor. The second motor drives the threaded rod to rotate.

[0007] According to the present invention, in an electronic wire bending resistance testing device, the end of the threaded rod furthest from the motor is rotatably connected to the base plate, and a slider is threadedly connected to the side surface of the threaded rod. The rotating threaded rod drives the slider to slide along the base plate.

[0008] According to the present invention, in an electronic wire bending resistance testing device, the side surface of the slider is slidably connected to the base plate, and the upper surface of the slider is fixedly connected to a bending plate. This allows the slider to move the bending plate.

[0009] According to the present invention, in a device for testing the bending resistance of electronic wires, a limiting rod is fixedly connected to the upper surface of a first fixed plate, and the side surface of the limiting rod is slidably connected to a second fixed plate. The limiting rod restricts the sliding of the second fixed plate, making its sliding more stable.

[0010] According to the present invention, in an electronic wire bending resistance testing device, one side surface of the shaft cylinder is rotatably connected to a first bending plate, and the side surface of the other shaft cylinder is rotatably connected to a second bending plate. This allows a first motor to drive the shaft cylinder to rotate between the first and second bending plates respectively.

[0011] According to the present invention, in an electronic wire bending resistance testing device, one side surface of the second fixing plate is slidably connected to the first bending plate, and the other side surface of the second fixing plate is slidably connected to the second bending plate. This allows the second fixing plate in the first and second bending plates to slide along their respective bending plates and fix the electronic wire to the first fixing plate.

[0012] According to the present invention, in an electronic wire bending resistance testing device, the side surface of the limiting plate is slidably connected to the slide rail, and the side surface of the sliding plate is slidably connected to the base plate. This allows the limiting plate to slide along the slide rail to limit electronic wires of different diameters, ensuring that the electronic wires can only bend upwards.

[0013] Beneficial effects:

[0014] Compared with existing technologies, this method uses a double-headed screw to drive a lower limit plate that limits the electronic wire according to its diameter, ensuring that the electronic wire can only bend upwards during the bending process. At the beginning of the bending, a sliding plate and a limit plate restrict the electronic wire to bend from the middle. During the bending process, an electric telescopic rod drives the limit plate to always be positioned on both sides of the electronic wire, avoiding the electronic wire's bending position and direction from being different each time, which would affect the detection effect. Furthermore, the screw drives the fixed plate to fix electronic wires of different diameters by rotating the shaft cylinder driven by a motor, improving the fixing effect.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-5 This utility model provides an electronic wire bending resistance testing device, which includes: a base plate 1, a bending plate 2 3 fixedly connected to the upper surface of the base plate 1, a bending plate 1 2 slidably connected to the upper surface of the base plate 1, a motor 4 fixedly connected to the upper surfaces of both the bending plate 1 2 and the bending plate 2 3, a fixing plate 5 fixedly connected to the inner side walls of both the bending plate 1 2 and the bending plate 2 3, a shaft cylinder 14 fixedly connected to the output end of the motor 1 4, a screw 17 threadedly connected to the inner side wall of the shaft cylinder 14, and a fixing plate 2 15 fixedly connected to the end of the screw 17 away from the shaft cylinder 14.

[0025] Specifically, both bending plate 12 and bending plate 23 are equipped with fixing plate 15 and fixing plate 25 inside. When it is necessary to fix the electronic wire, the screw 17 drives the fixing plate 25 to move in the vertical direction by the rotation of the shaft cylinder 14 driven by motor 14 and the limitation of the limit rod 16. Together with fixing plate 15, the two ends of the electronic wire are fixed on bending plate 12 and bending plate 23 respectively. During the detection process, the electronic wire will be bent by the movement of one end of the electronic wire driven by bending plate 12.

[0026] An electric telescopic rod 8 is fixedly connected to the side surface of the bending plate 12. A slide plate 9 is fixedly connected to the output end of the electric telescopic rod 8. The side surface of the slide plate 9 is slidably connected to the base plate 1. An electric telescopic rod 19 is fixedly connected to the upper surface of the slide plate 9. A slide rail 10 is fixedly connected to the output end of the electric telescopic rod 19. A motor 11 is fixedly connected to the side surface of the slide rail 10. A double-headed screw 18 is fixedly connected to the output end of the motor 11. A limit plate 12 is threadedly connected to the side surface of the double-headed screw 18. The side surface of the limit plate 12 is slidably connected to the slide rail 10.

[0027] Specifically, the bending plate 2 and the sliding plate 9 are connected by an electric telescopic rod 8, and the distance between the bending plate 2 and the sliding plate 9 is adjusted by the electric telescopic rod 8. At the same time, the surface of the sliding plate 9 is provided with a through hole, the diameter of which is larger than the diameter of the threaded rod 7, so that the movement of the sliding plate 9 is not affected by the threaded rod 7. Before the test begins, the double-headed screw 18 is rotated by the motor 3 11, which moves the two limiting plates 12 inward and makes the distance between the two limiting plates 12 slightly larger than the diameter of the electronic wire. When the test begins, the two limiting plates 12 limit the electronic wire to bend upward, and under the action of the electric telescopic rod 8 and the electric telescopic rod 2 19, the bent part of the electronic wire is always located between the two limiting plates 12.

[0028] A second motor 6 is fixedly connected to the side surface of the base plate 1. A threaded rod 7 is fixedly connected to the output end of the second motor 6. The end of the threaded rod 7 away from the second motor 6 is rotatably connected to the base plate 1. A slider 13 is threadedly connected to the side surface of the threaded rod 7. The side surface of the slider 13 is slidably connected to the base plate 1. The upper surface of the slider 13 is fixedly connected to the bending plate 2.

[0029] Specifically, motor 6 drives threaded rod 7 to rotate. After the threaded rod 7 rotates, it will drive bending plate 2 to move along the base plate 1 through slider 13, so that bending plate 2 can drive one end of the electronic wire to move and bend the electronic wire.

[0030] A limiting rod 16 is fixedly connected to the upper surface of the fixing plate 15. The side surface of the limiting rod 16 is slidably connected to the fixing plate 2. The side surface of one shaft cylinder 14 is rotatably connected to the bending plate 2. The side surface of the other shaft cylinder 14 is rotatably connected to the bending plate 2. The side surface of one fixing plate 25 is slidably connected to the bending plate 2. The side surface of the other fixing plate 25 is slidably connected to the bending plate 2.

[0031] Specifically, both bending plate 12 and bending plate 23 are equipped with a set of motor 14, shaft cylinder 14, screw 17, fixing plate 25 and fixing plate 15. The motor 14 drives the shaft cylinder 14 to rotate, which enables the screw 17 to drive the fixing plate 25 to move and fix the electronic wire between fixing plate 15 and fixing plate 25. The fixing plate 15 is also equipped with a limiting rod 16, which allows the fixing plate 25 to slide only along the limiting rod 16 during the movement, so that the fixing plate 25 can slide stably and fix the electronic wire.

[0032] Working principle: Before use, adjust the slide plate 9 to be between the bending plate 1 (2) and the bending plate 2 (3). Then, pass the electronic wire between the bending plate 1 (2) and the bending plate 2 (3) and position it above the slide plate 10. Then, simultaneously start the motor 1 (4) on the bending plate 1 (2) and the bending plate 2 (3). The motor 1 (4) drives the shaft cylinder 14 to rotate, and under the restriction of the limit rod 16, the screw 17 drives the fixing plate 2 (15) to move vertically. Together with the fixing plate 1 (5), the two ends of the electronic wire are fixed to the bending plate 1 (2) and the bending plate 2 (3) respectively. Then, start the motor 3 (11) to drive the double-headed screw 18 to rotate, so that the two limit plates 12 on both sides move inward and the distance between the two limit plates 12 is slightly larger. Regarding the diameter of the electronic wire, when the test begins, motor 6 drives the threaded rod 7 to rotate. After the threaded rod 7 rotates, it will drive the bending plate 2 to move along the base plate 1 through the slider 13, so that the bending plate 2 can drive one end of the electronic wire to move and bend the electronic wire. The electronic wire can only bend upward under the restriction of the limiting plate 12. At the same time, during the initial bending process, the limiting plate 12 will always be located on both sides of the electronic wire under the drive of the electric telescopic rod 8 and the electric telescopic rod 19, so that the bending point of the electronic wire is fixed and multiple bending points are avoided in the first few bending processes. Afterwards, the bending plate 2 will move back and forth under the drive of the threaded rod 7, and drive the electronic wire to bend repeatedly until it breaks.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
