Description

Technical Field

[0001] This application relates to the technical field of flat wire bending inspection fixtures, and in particular to a flat wire bending inspection fixture. Background Technology

[0002] Flat wire, also known as flat conductor or flat wire, is widely used in numerous electrical equipment and electronic components. In the production process of flat wire, its bending performance is an important quality indicator. Flat wire with poor bending performance may experience breakage, poor contact, and other problems in actual use, affecting the normal operation of equipment. The flexibility of enameled wire is tested through a round bar bending test. Enameled copper flat wires of different sizes are bent 180 degrees along both the wide and narrow sides of a round bar of a specified diameter, and the enamel film on the bent portion of the sample is then examined for cracking.

[0003] However, the market currently lacks an efficient, accurate, and easy-to-operate flat wire bending inspection fixture. Existing inspection methods often suffer from low inspection accuracy, complex operation, and inability to simulate various bending conditions, failing to meet the needs of production and quality control. Moreover, existing round bar bending test specimens are bent by clamping enameled copper flat wires with fixtures, which easily damages the enamel film, leading to misjudgments and affecting the accuracy of the test. Utility Model Content

[0004] In order to safely inspect flat wires of different sizes, this application provides a flat wire bending inspection fixture.

[0005] The flat wire bending inspection fixture provided in this application adopts the following technical solution: A flat wire bending inspection fixture includes an equipment tray, an inspection tray mounted on the upper surface of the equipment tray, the inspection tray being rotatably connected to the equipment tray, and an angle motor for driving the inspection tray to rotate fixedly mounted on the lower surface of the equipment tray. A positioning seat is also mounted on the edge of the upper surface of the equipment tray, the positioning seat being fixedly connected to the equipment tray. A bending bracket is also fixedly mounted on the upper surface of the positioning seat, the bending bracket being disposed on the upper end of the inspection tray, and a limit pusher at the head of the bending bracket. A positioning rod is also vertically fixed at the center of the inspection tray. During inspection, the limit pusher and the positioning rod clamp the two ends of the flat wire. An adjustable pressure seat is also mounted on the upper surface of the inspection tray.

[0006] By adopting the above technical solution, and by setting up a rotatable inspection disc driven by an angle motor, the bending of the flat wire at different angles can be simulated, improving the accuracy and comprehensiveness of the inspection. The positioning seat and bending bracket provide stable support and installation position for the limiting pusher, enabling it to accurately limit and push the flat wire. The positioning vertical rod, in conjunction with the limiting pusher, firmly clamps both ends of the flat wire, ensuring its stability during inspection. The adjustable pressure seat allows for appropriate clamping of the flat wire according to its different specifications and inspection requirements, further improving the reliability of the inspection.

[0007] Optionally, the fixed bending bracket includes a connecting seat and a guide frame for sliding installation of the limiting push frame. The connecting seat is fixedly installed on the upper end face of the positioning seat, and the guide frame is integrally formed and disposed at one end of the connecting seat.

[0008] By adopting the above technical solution, the fixed bending support adopts a structural design in which the connecting seat and the guide frame are integrally formed. This not only ensures the overall strength and stability of the fixed bending support, but also allows the limiting pusher to slide smoothly on the guide frame, improving the movement accuracy of the limiting pusher, thereby more accurately positioning and pushing the flat line.

[0009] Optionally, the guide frame includes a vertical plate and a transverse screw for adjusting the position of the limiting pusher. The transverse screw is threaded onto the vertical plate, and the head of the transverse screw is rotatably connected to the limiting pusher.

[0010] By adopting the above technical solution, the guide frame adjusts the position of the limiting pusher via a transverse screw. This threaded adjustment method features high adjustment accuracy and convenient operation. By rotating the transverse screw, the movement distance of the limiting pusher can be precisely controlled, thus adapting to the inspection requirements of flat wires of different specifications. A trapezoidal threaded screw can be selected for the transverse screw, which has high transmission efficiency and self-locking performance.

[0011] Optionally, the limiting pusher includes a push plate and a guide rod. The guide rod is fixedly installed on both sides of the rear end face of the push plate and is slidably installed on the vertical plate.

[0012] By adopting the above technical solution, the design of the push plate and guide rod of the limiting pusher makes the limiting pusher more stable and smooth during movement. The guide rod slides on the vertical plate, providing good guidance for the push plate and preventing it from deviating during movement, thus ensuring accurate pushing of the flat wire.

[0013] Optionally, the push plate includes a slider, an arc-shaped disk, and a top plate. The arc-shaped disk is mounted on the front end face of the slider, and the top plate is mounted on the upper end face of the arc-shaped disk. The slider, the arc-shaped disk, and the top plate are integrally formed.

[0014] By adopting the above technical solution, the integrated structure of the slider, arc-shaped disk, and top plate of the pusher not only ensures the overall strength of the pusher, but also allows the design of the arc-shaped disk and top plate to better conform to the shape of the flat wire, improving the limiting and pushing effect on the flat wire. When pushing the flat wire, force can be applied more evenly, avoiding excessive local stress on the flat wire and thus preventing damage.

[0015] Optionally, the adjustable pressure seat includes a positioning slide, a pressure block, and a longitudinal screw. The positioning slide is vertically fixed to the upper surface of the inspection disc, the pressure block is slidably mounted on the positioning slide, and the longitudinal screw is threadedly connected to the positioning slide, with the lower end of the longitudinal screw rotatably connected to the pressure block.

[0016] By adopting the above technical solution, the adjustable pressure seat adjusts the position of the pressure block through a longitudinal screw to achieve the clamping of the flat wire. This structural design is simple and easy to operate, and can flexibly adjust the clamping force according to the different thicknesses of the flat wire and inspection requirements, ensuring that the flat wire will not loosen during inspection. A common triangular threaded screw can be used for the longitudinal screw, facilitating processing and installation.

[0017] Optionally, the upper end face of the positioning slide is provided with a threaded sleeve for mounting the longitudinal screw, the threaded sleeve is fixedly connected to the positioning slide, and the head of the longitudinal screw is also fixedly mounted with an operating disc.

[0018] By adopting the above technical solution, the threaded sleeve on the positioning slide provides a stable installation and transmission structure for the longitudinal screw, ensuring the stability of the longitudinal screw's rotation and movement. The control panel facilitates the operator's rotation of the longitudinal screw, improving operational convenience.

[0019] Optionally, a pressing groove is provided on one side of the pressing block for the flat wire to pass through, and an anti-slip inner pad is installed in the pressing groove and is glued and fixed to the pressing block.

[0020] By adopting the above technical solution, the design of the pressing groove and anti-slip inner pad on the pressing block can better fix the flat wire and prevent it from slipping during inspection. The anti-slip inner pad can increase the friction between the flat wire and the anti-slip inner pad, improving the pressing effect.

[0021] In summary, this application includes at least one of the following beneficial technical effects: By using a rotatable inspection disc, a precise limiting pusher, and a positioning vertical rod, this application can simulate the bending of flat wire under different angles and conditions, enabling a comprehensive and accurate inspection of the bending performance of the flat wire, greatly improving inspection accuracy. The use of a threaded adjustment method to adjust the position of the limiting pusher and the pressure block allows operators to easily complete the adjustment by simply rotating the screw, simplifying operation and reducing operator workload. The adjustable pressure seat and limiting pusher positions can adapt to the inspection needs of flat wires of different specifications and thicknesses, improving the versatility and applicability of the fixture.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a fixture for inspecting flat wire bending. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, a flat wire bending inspection fixture includes an equipment disk 1, an inspection disk 2 mounted on the upper surface of the equipment disk 1, the inspection disk 2 being rotatably connected to the equipment disk 1, and an angle motor for driving the inspection disk 2 to rotate fixedly mounted on the lower surface of the equipment disk 1. A positioning seat 3 is also mounted at the edge of the upper surface of the equipment disk 1, fixedly connected to the equipment disk 1. A bending support 4 is also fixedly mounted on the upper surface of the positioning seat 3, positioned on the upper end of the inspection disk 2, and has a limit pusher 5 at its head. A positioning rod 6 is vertically fixed at the center of the inspection disk 2. During inspection, the limit pusher 5 and the positioning rod 6 clamp the two ends of the flat wire. An adjustable pressure seat 7 is also mounted on the upper surface of the inspection disk 2. By setting a rotatable inspection disk 2 and driving it to rotate using an angle motor, the bending of the flat wire at different angles can be simulated, improving the accuracy and comprehensiveness of the inspection. The positioning seat 3 and the bending bracket 4 provide stable support and installation position for the limiting pusher 5, enabling it to accurately limit and push the flat wire. The positioning vertical rod 6, in conjunction with the limiting pusher 5, firmly clamps both ends of the flat wire, ensuring its stability during inspection. The adjustable pressure seat 7 allows for appropriate clamping of the flat wire according to its specifications and inspection requirements, further improving inspection reliability. A stepper motor, such as a 57 stepper motor, can be used for the angle motor, providing high-precision angle control and accurately controlling the rotation angle of the inspection disc 2.

[0030] Reference Figure 2 and Figure 4 As shown, the bending support 4 includes a connecting seat 41 and a guide frame 42 for sliding installation of the limiting push frame 5. The connecting seat 41 is fixedly installed on the upper end face of the positioning seat 3, and the guide frame 42 is integrally formed at one end of the connecting seat 41. The bending support 4 adopts an integrally formed structural design of the connecting seat 41 and the guide frame 42, which not only ensures the overall strength and stability of the bending support 4, but also allows the limiting push frame 5 to slide smoothly on the guide frame 42, improving the movement accuracy of the limiting push frame 5, thereby more accurately positioning and pushing the flat wire. The connecting seat 41 and the guide frame 42 can be made of high-strength aluminum alloy material, such as 6061 aluminum alloy, which has the advantages of light weight, high strength, and corrosion resistance. The guide frame 42 includes a vertical plate part 421 and a transverse screw 422 for adjusting the position of the limiting push frame 5. The transverse screw 422 is threadedly connected to the vertical plate part 421, and the head of the transverse screw 422 is rotatably connected to the limiting push frame 5. The guide frame 42 adjusts the position of the limiting pusher 5 via a transverse screw 422. This threaded adjustment method features high adjustment accuracy and convenient operation. By rotating the transverse screw 422, the movement distance of the limiting pusher 5 can be precisely controlled, thus adapting to the inspection requirements of flat wires of different specifications. The transverse screw 422 can be a trapezoidal thread screw, which has high transmission efficiency and self-locking performance.

[0031] Reference Figure 2 and Figure 4 As shown, the limiting pusher 5 includes a push plate portion 51 and a guide rod 52. The guide rod 52 is fixedly installed on both sides of the rear end face of the push plate portion 51, and is slidably installed on the vertical plate portion 421. The design of the push plate portion 51 and the guide rod 52 of the limiting pusher 5 makes the limiting pusher 5 more stable and smooth during movement. The guide rod 52 slides on the vertical plate portion 421, providing good guidance for the push plate portion 51, preventing the push plate portion 51 from deviating during movement, and ensuring accurate pushing of the flat wire. The guide rod 52 can be made of stainless steel, such as 304 stainless steel, which has good wear resistance and corrosion resistance. The push plate portion 51 includes a slider 511, an arc-shaped disk 512, and a top plate 513. The arc-shaped disk 512 is installed on the front end face of the slider 511, and the top plate 513 is installed on the upper end face of the arc-shaped disk 512. The slider 511, the arc-shaped disk 512, and the top plate 513 are integrally formed. The integrated structure of the slider 511, arc-shaped disk 512, and top disk 513 in the push plate section 51 not only ensures the overall strength of the push plate section 51, but also allows the design of the arc-shaped disk 512 and top disk 513 to better conform to the shape of the flat wire, improving the limiting and pushing effect on the flat wire. When pushing the flat wire, force can be applied more evenly, avoiding damage caused by excessive localized force. The slider 511, arc-shaped disk 512, and top disk 513 can be made of engineering plastics, such as polyoxymethylene (POM), which has good wear resistance and self-lubricating properties.

[0032] Reference Figure 3 and Figure 5As shown, the adjustable pressure seat 7 includes a positioning slide 71, a pressure block 72, and a longitudinal screw 73. The positioning slide 71 is vertically fixed to the upper surface of the inspection disc 2. The pressure block 72 is slidably mounted on the positioning slide 71. The longitudinal screw 73 is threadedly connected to the positioning slide 71, and its lower end is rotatably connected to the pressure block 72. The adjustable pressure seat 7 adjusts the position of the pressure block 72 via the longitudinal screw 73 to achieve the pressing of the flat wire. This structure is simple in design and easy to operate. It can flexibly adjust the pressing force according to the different thicknesses of the flat wire and inspection requirements, ensuring that the flat wire will not loosen during inspection. The longitudinal screw 73 can be a common triangular threaded screw, which is easy to process and install. The upper surface of the positioning slide 71 is provided with a threaded sleeve 711 for mounting the longitudinal screw 73. The threaded sleeve 711 is fixedly connected to the positioning slide 71, and the head of the longitudinal screw 73 is also fixedly mounted with an operating disc 731. The threaded sleeve 711 on the positioning slide 71 provides a stable mounting and transmission structure for the longitudinal screw 73, ensuring the stability of the rotation and movement of the longitudinal screw 73. The operating disc 731 facilitates the operator's rotation of the longitudinal screw 73, improving operational convenience. The threaded sleeve 711 can be made of copper alloy material, such as brass, which has good wear resistance and corrosion resistance. The operating disc 731 can be made of rubber material with anti-slip textured surface for easy gripping and rotation. One side of the pressure block 72 has a pressure-holding groove for the flat wire to pass through, and an anti-slip inner pad 721 is installed in the pressure-holding groove and is adhesively fixed to the pressure block 72. The design of the pressure-holding groove and the anti-slip inner pad 721 on the pressure block 72 better secures the flat wire and prevents it from slipping during inspection. The anti-slip inner pad 721 increases the friction between the flat wire and the anti-slip pad, improving the clamping effect. The anti-slip inner pad 721 can be made of rubber materials, such as nitrile rubber, which has good anti-slip properties and elasticity.

[0033] The implementation principle of a flat wire bending inspection fixture according to this application embodiment is as follows: During actual testing, based on the specifications and inspection requirements of the flat wire, the horizontal screw 422 is rotated to adjust the position of the limiting pusher 5 so that the distance between it and the positioning vertical rod 6 is suitable for the length of the flat wire. One end of the flat wire is passed through the pressing groove of the pressing block 72 of the adjustable pressing seat 7, and the longitudinal screw 73 is rotated to move the pressing block 72 downward through the operating disc 731 to press the flat wire. The other end of the flat wire is placed between the arc-shaped disc 512 and the top disc 513 of the push plate part 51 of the limiting pusher 5 to ensure that the flat wire is firmly clamped. The angle motor is started to drive the inspection disc 2 to rotate according to the preset angle program, simulating the bending of the flat wire at different angles. During the inspection process, the bending of the flat wire is observed to check whether there are problems such as breakage or deformation. After the inspection is completed, the angle motor is turned off, the longitudinal screw 73 is rotated to release the pressing block 72, and the flat wire is taken out.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
