At present, the flexibility testing method of insulated wires is manual bending or bending with auxiliary tools. The operation is cumbersome, there are many processes, and manual adjustment is required. The bending angles of insulated wires of the same specification have errors each time and cannot be unified.

Detailed Embodiment

[0027] The flexible detection device for insulated wires provided by the present utility model will be explained and described in detail below with reference to the accompanying drawings of the specification.

[0028] This embodiment specifically discloses a flexible detection device for insulated wires, as shown in Figures 1-3As shown, it includes a base 1, a winding disc 2, a winding column 3, a winding driving mechanism 4, a clamping and positioning mechanism 5, and a winding mechanism 6. The winding disc 2 is fixed on the base 1 and is rotatably connected to the base 1. The winding column 3 is detachably fixed at the center of the winding disc 2. The winding column 3 can be replaced according to the specifications of the insulated wire to be measured, so as to be applicable to the detection of insulated wires of different specifications. The winding driving mechanism 4 drives the winding disc 2 to rotate around the central axis of the winding column 3. The winding driving mechanism 4 is a motor or a rotary cylinder. In this embodiment, the winding disc 2 is a disc, and the central axis of the winding disc 2 coincides with the central axis of the winding column 3. As Figure 1 , 2 and as shown in 4, the base 1 includes a top plate 11, a bottom plate 12, and support columns 13 connected between the top plate 11 and the bottom plate 12. The number of support columns 13 is 4. The 4 support columns 13 are distributed in a rectangle between the bottom plate 12 and the top plate 11. The base of the winding driving mechanism 4 is fixed on the bottom plate 12, the winding disc 2 is fixed on the top plate 11, and the output shaft of the winding driving mechanism 4 is fixedly connected to the winding disc 2. As Figure 4 shown, the winding disc 2 includes a winding disc body at the top and a chassis below the winding disc body. The chassis is used for rotatably connecting with the top plate 11. A hole for the chassis to pass through is opened on the top plate 11. The chassis is fixedly connected to the output shaft of the winding driving mechanism 4 by screws. The chassis and the top plate 11 can be rotatably connected through a bearing. A bearing is sleeved outside the chassis. The inner ring of the bearing is fixedly connected to the chassis, and the outer ring of the bearing is fixedly connected to the hole wall of the hole on the top plate 11 for the chassis to pass through, realizing the fixation and rotational connection of the winding disc 2 and the base 1.

[0029] As Figure 1 and 4 shown, the winding column 3 includes a winding part 31 at the top and a mounting part 32 at the bottom. The winding part 31 is used for bending and winding the insulated wire to be measured. An installation hole is opened at the center of the winding disc 2. The mounting part 32 is installed in the installation hole, and the upper end surface of the mounting part 32 is flush with the top surface of the winding disc 2. The winding column 3 can be provided with multiple specifications. The sizes of the mounting parts 32 of each specification of the winding column 3 are the same, and the winding parts 31 have different specifications, that is, the winding parts have different diameters. By replacing the winding column 3 with different specifications of the winding part 31, it can adapt to insulated wires to be measured of different specifications. In this embodiment, the mounting part 32 can be in interference fit with the installation hole, and the winding column 3 can rotate together with the winding disc 2 to prevent the insulation layer on the surface of the insulated wire to be measured from being worn out during winding; the outer diameter of the mounting part 32 can also be slightly smaller than the diameter of the installation hole, and the mounting part 32 is placed in the installation hole.

[0030] As Figures 1-3As shown, a winding drive switch 41 for controlling the start and stop of the winding drive mechanism 4 is provided on the side of the base 1, which is convenient for operation, making the rotation angle of the winding disc 2 relative to the base 1 easier to control and accurately controllable. The winding drive mechanism 4 is a motor or a rotary cylinder. By controlling the rotation angle of the motor or the rotary cylinder, the rotation angle of the winding disc 2 relative to the base 1 can be controlled. The operation is more convenient and the control is more accurate.

[0031] Optionally, an angle scale is provided on the outer periphery of the disc surface of the winding disc 2, and a pointer for indicating the angle scale is fixed on the base 1. The pointer is fixed on the top plate 11, and the tip of the pointer extends above the angle scale of the winding disc 2. The range of the angle scale can be set to 360°, and the minimum unit of the angle scale is 1°. The pointer initially points to the 0° scale line of the angle scale, and the rotation angle of the winding disc 2 relative to the base 1 is displayed by the angle scale pointed to by the pointer.

[0032] As Figures 1-4 As shown, the clamping and positioning mechanism 5 is fixed on the base 1 and extends above the winding disc 2, pressing the insulating wire to be tested on the winding disc 2 and on the side of the winding column 3. Specifically, the clamping and positioning mechanism 5 includes a downward pressing mechanism 51 and a side pressing mechanism 52. The side pressing mechanism 52 is fixed on the base 1 and extends above the winding disc 2 and is located on the side of the downward pressing mechanism 51. The side pressing mechanism 52 presses on the side of the insulating wire to be tested away from the winding column 3. The downward pressing mechanism 51 is fixedly connected to the side pressing mechanism 52. The downward pressing mechanism 51 presses above the insulating wire to be tested and presses the insulating wire to be tested on the winding disc 2. The downward pressing mechanism 51 is an electric telescopic rod, a linear cylinder or a hydraulic cylinder. A downward pressing mechanism switch 53 is fixed on the side of the base 1 to control the downward pressing stroke of the downward pressing mechanism 51, ensuring that the insulating wire is tightly pressed while avoiding damaging the insulating wire. When the downward pressing mechanism 51 is a linear cylinder, a pressure regulating valve 7 can be provided on the top plate 11 to adjust the pressure of the linear cylinder through the pressure regulating valve 7. The side pressing mechanism 52 and the downward pressing mechanism 51 cooperate to fix the insulating wire to be tested on the winding disc 2 and on the side of the winding column 3. Preferably, the side of the insulating wire to be tested is in contact with the winding column 3.

[0033] As Figures 1-6 As shown, the side pressing mechanism 52 includes a first screw 521, a first fixing block 522 and a first slider 523. One end of the first fixing block 522 is fixedly connected to the base 1, and the other end of the first fixing block 522 extends above the winding disc 2. The first screw 521 is threadedly connected to the first fixing block 522. One end of the first screw 521 close to the winding disc 2 is rotatably connected to the first slider 523. As Figure 1As shown, the end of the first screw rod 521 close to the winding disc 2 is stepped, and the part with a larger diameter of the stepped structure is close to the first slider 523. A stepped groove matching the stepped end of the first screw rod 521 is formed on the first slider 523. The stepped end of the first screw rod 521 is clamped into the stepped groove of the first slider 523 and can rotate in the stepped groove. The first slider 523 is slidably connected to the first fixed block 522, and the first slider 523 slides in the direction close to or away from the winding column 3. As Figure 5 and 6 shown, a first sliding groove is provided on one of the top surface of the first fixed block 522 and the bottom surface of the first slider 523, and a first convex block matching the first sliding groove is provided on the other. In this embodiment, a T-shaped first sliding groove is formed on the bottom surface of the first slider 523, and a T-shaped first convex block is provided on the top surface of the first fixed block 522. The first sliding groove is stuck on the first convex block. When the first screw rod 521 rotates, the first screw rod 521 pushes the first slider 523 to slide along the first fixed block 522 in the direction close to or away from the winding column 3. Optionally, a first stop block 54 is fixed to the end of the first slider 523 away from the first screw rod 521, and the fixed end of the pressing mechanism 51 is fixedly connected to the first stop block 54. The setting of the first stop block 54 increases the contact area with the insulating wire to be measured. When the first screw rod 521 drives the first slider 523 to move, the first stop block 54 moves with the first slider 523, and thus the distance between the first stop block 54 and the winding column 3 can be adjusted to adapt to insulating wires of different specifications. The pressing mechanism 51 also moves with the movement of the first stop block 54. A Teflon pressing block can be fixed to the telescopic end of the pressing mechanism 51 to ensure the pressure intensity. The pressing mechanism 51 and the side pressing mechanism 52 cooperate to fix the insulating wire to be measured on the winding disc 2 and keep it stationary.

[0034] As Figures 1-3 shown in FIGS. 4 and 5, the winding mechanism 6 is fixed on the winding disc 2. The winding mechanism 6 presses on the side of the insulating wire to be measured away from the winding column 3. The winding mechanism 6 presses the insulating wire to be measured towards the winding column 3. The winding mechanism 6 rotates with the rotation of the winding disc 2 and winds the insulating wire to be measured around the winding column 3.

[0035] As Figures 1-3 shown in FIGS. 4 and 5, the winding mechanism 6 includes a second screw rod 61, a second fixed block 62 and a second slider 63. The second fixed block 62 is fixed on the winding disc 2. The second screw rod 61 is threadedly connected to the second fixed block 62. One end of the second screw rod 61 close to the winding column 3 is rotatably connected to the second slider 63. The second slider 63 is slidably connected to the second fixed block 62. The second slider 63 slides in the direction close to or away from the winding column 3. As Figure 1As shown, the end of the second screw rod 61 close to the winding column 3 is stepped. The part with a larger diameter of the stepped structure is close to the second slider 63. A stepped groove matching the stepped end of the second screw rod 61 is formed on the second slider 63. The stepped end of the second screw rod 61 is stuck into the stepped groove of the second slider 63 and can rotate in the stepped groove. The second slider 63 is slidably connected to the second fixed block 62, and the second slider 63 slides in the direction close to or away from the winding column 3. As Figure 5 shown, a second sliding groove is provided on one of the top surface of the second fixed block 62 and the bottom surface of the second slider 63, and a second convex block matching the second sliding groove is provided on the other. In this embodiment, a T-shaped second sliding groove is formed on the bottom surface of the second slider 63, and a T-shaped second convex block is provided on the top surface of the second fixed block 62. The second sliding groove is stuck on the second convex block. When the second screw rod 61 rotates, the second screw rod 61 pushes the second slider 63 to slide along the second fixed block 62 in the direction close to or away from the winding column 3. Optionally, a second stopper 64 is fixed to the end of the second slider 63 away from the second screw rod 61. The setting of the second stopper 64 increases the contact area with the insulating wire to be tested. When the second screw rod 61 drives the second slider 63 to move, the second stopper 64 moves with the second slider 63, and thus the distance between the second stopper 64 and the winding column 3 can be adjusted to adapt to insulating wires of different specifications.

[0036] In the embodiment of the present application, both the side pressing mechanism 52 and the winding mechanism 6 adopt the principle of a lead screw. The side pressing mechanism 52 and the winding mechanism 6 cooperate to press from the side of the insulating wire to be tested and push the insulating wire to be tested against the winding column 3. The side pressing mechanism 52 and the downward pressing mechanism 51 keep the insulating wire to be tested fixed. The winding mechanism 6 rotates with the winding disc 2 and thus rotates around the winding column 3 to wind the insulating wire to be tested around the winding column 3 by bending.

[0037] In this embodiment, the top plate 11, the bottom plate 12, and the winding disc 2 are all made of aluminum, the support column 13 is made of steel, the winding column 3 is made of steel, and the first screw rod 521, the second screw rod 61, the first slider 523, the second slider 63, the first fixed block 522, the second fixed block 62, the first stopper 54, and the second stopper 64 are all made of steel to ensure the structural strength of the entire detection device.

[0038] Taking the flexibility detection of a flat insulating wire as an example, the method for detecting the flexibility of an insulating wire using the insulating wire flexibility detection device of the embodiment of the present application is described as follows:

[0039] Select a suitable winding column 3 according to the specifications of the flat insulated wire to be tested, install it on the winding disc 2, place the flat insulated wire to be tested on the side of the winding column 3 and between the side pressure mechanism 52, the winding mechanism 6 and the winding column 3, so that the winding side of the flat insulated wire to be tested is close to the winding column 3. Adjust the positions of the first stopper 54 and the second stopper 64 by rotating the first screw 521 and the second screw 61. The first stopper 54 and the second stopper 64 move towards the flat insulated wire to be tested until they press on the side of the flat insulated wire to be tested, and clamp the flat insulated wire to be tested between the first stopper 54, the second stopper 64 and the winding column 3. At this time, the first stopper 54 and the second stopper 64 are arranged side by side and are on the same straight line (such as Figure 1 and 3In the state shown, press the switch 53 of the downward pressing mechanism. The downward pressing mechanism 51 moves downward and presses on the flat insulating wire to be tested. If the downward pressing mechanism 51 is a linear cylinder, the pressure value of the linear cylinder can be adjusted through the pressure regulating valve 7 to avoid damaging the flat insulating wire to be tested due to excessive pressure. At this time, the flat insulating wire to be tested remains stationary. Then, press the winding drive switch 41. The winding disc 2 rotates, and the winding mechanism 6 rotates with the rotation of the winding disc 2, bending and winding the flat insulating wire to be tested around the winding column 3. The rotation angle of the winding disc 2 is determined by the angle scale pointed by the pointer. When the winding disc 2 rotates to the required angle value, stop the rotation of the winding disc 2, thus realizing the automatic bending process. When the winding disc 2 rotates, under the pressure action of the downward pressing mechanism 51 and the side pressing mechanism 52, the flat insulating wire to be tested still remains stationary and is only wound around the winding column 3 through the action of the winding mechanism 6. Although the rotation of the winding disc 2 will cause slight wear on the bottom of the flat insulating wire to be tested, the wear on the bottom is not an index for judging the flexible wire detection and does not affect the flexible detection result. After stopping winding, the included angle between the two ends of the flat insulating wire to be tested can be viewed through the angle scale on the winding disc 2, and then the rebound angle can be calculated; check whether there are cracks at the winding position of the flat insulating wire to be tested, and then it can be judged whether the flexibility of the flat insulating wire to be tested meets the requirements. When detecting other flat insulating wires with the same radius again, first press the switch 53 of the downward pressing mechanism to make the telescopic end of the downward pressing mechanism 51 move upward to release the flat insulating wire that has completed winding. Reverse-rotate the first screw rod 521 and the second screw rod 61 to make the first stop block 54 and the second stop block 64 retract backward by a certain distance, take out the flat insulating wire that has completed winding, then place the new flat insulating wire to be tested at the specified position, and then rotate the first screw rod 521 and the second screw rod 61 until the front end faces of the first stop block 54 and the second stop block 64 contact the flat insulating wire to be tested, clamp the flat insulating wire to be tested between the first stop block 54, the second stop block 64 and the winding column 3, then press the switch 53 of the downward pressing mechanism, and the downward pressing mechanism 51 presses above the flat insulating wire to be tested, and then repeat the above winding steps to complete the detection of another flat insulating wire. If detecting flat insulating wires of different specifications, the corresponding specification of the winding column 3 needs to be replaced. The whole detection process has simple procedures and mechanized detection, improving the detection precision and operation efficiency.

[0040] Insulating wires of the same specification are bent and wound using the same winding column 3, and the bending angle is the same each time, making the detection results more accurate.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and simple improvements made on the substantial content of the present invention shall be included within the protection scope of the present invention.
