A lead-cutting device for wire assembly processing

Abstract

This utility model discloses a lead-cutting device for wire assembly processing, relating to the field of wire assembly processing. The device includes a base, a support frame fixed to one side of the top of the base, and a fixed box mounted on the top of the base. The device incorporates a servo motor, a worm gear, a worm wheel, a rotating shaft, a screw hole, a threaded post, and a support plate. After the leads are cut, they accumulate on the support plate. At this time, a hydraulic cylinder activates, causing the cutter to move upwards and reset. Simultaneously, the servo motor is activated, driving the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft's rotation moves the threaded post, which in turn moves the lifting plate upwards, causing the rotating plate to rotate. The rotating plate then drives the support plate to rotate, causing the support plate to tilt towards the collection box. The cut leads accumulated on the support plate automatically slide into the collection box, preventing workers from accidentally bumping the cutter when manually handling residual material, thus improving safety.

Description

Technical Field

[0001] This utility model relates to the field of wire assembly processing, specifically a lead-cutting device for wire assembly processing. Background Technology

[0002] Lead cutting devices for wire assembly processing are key equipment in the production and processing of wire assemblies such as wires and cables, electronic wire harnesses, and connectors. They are mainly used to precisely cut and trim the leads, wire ends, or excess wire segments of wire assemblies to meet preset length, flatness, or shape requirements.

[0003] According to Chinese Patent No. CN214212054U, a lead-cutting device for wire assembly processing is disclosed. This utility model is equipped with a power mechanism, a transmission mechanism, and an auxiliary mechanism. When cutting off the lead of a wire, the lead of the wire only needs to be placed directly below the cutter head, and the remaining part is placed on a first platform. The operator only needs to manually pull down the handle to move the cutter head down, thereby cutting off the lead. During the downward movement of the cutter head, the power rod moves down accordingly, which in turn pushes the transmission rod upward through hydraulic oil, thereby moving the push rod upward. The push rod then moves the support plate upward, using the support plate to support the lead of the wire and prevent the cutter head from failing to cut due to insufficient force.

[0004] Regarding the aforementioned patent content, after the wire leads are cut, the cut residue will accumulate directly on the surface of the support plate used to support the wires. To avoid affecting the processing of the next batch of wire assemblies, the residue needs to be manually removed from the support plate. Since the support plate is located directly below the cutter, and although the cutter moves up and resets after cutting, it is still in close proximity to the support plate, if manual cleaning of the accumulated residue is required, the worker's hand needs to reach into the area between the cutter and the support plate. This makes it very easy to touch the cutter due to operational errors or sudden equipment movements (such as accidentally touching the start switch and causing the cutter to fall), resulting in cuts and other safety accidents, thereby reducing the safety of equipment use. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a cutting device for processing wire assemblies, so as to solve the technical problem that workers may accidentally touch the cutting blade and cause hand cuts when manually cleaning the residual material on the support plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing wire assemblies, comprising a base, a support frame fixed to one side of the top of the base, a fixed box installed on the top of the base, and a rotating shaft connected to the lower interior of the fixed box via a bearing, and a support plate installed on the upper side of one side of the fixed box via a hinge, the rotating shaft having a threaded hole inside, and a threaded post threaded inside the threaded hole, a lifting plate installed at the top of the threaded post, the lifting plate and the support plate being rotatably connected via the rotating shaft, a worm gear installed on the outer wall of the rotating shaft, and a servo motor installed on the lower other side of the fixed box, with a worm gear connected to the output end of the servo motor.

[0007] By adopting the above technical solution, the rotating shaft can drive the threaded column to move when it rotates, which in turn drives the lifting plate to move, which in turn drives the rotating plate to rotate, and the rotating plate can drive the support plate to rotate, thereby adjusting the tilt angle of the support plate.

[0008] Furthermore, one end of the worm is connected to the inner wall of the fixed box via a bearing, and the worm meshes with a worm wheel.

[0009] By adopting the above technical solution, when the worm rotates, it will drive the worm wheel to rotate, which in turn drives the shaft to rotate, and in turn drives the screw hole to rotate.

[0010] Furthermore, a guide rod is installed inside the upper part of the fixed box, and the guide rod passes through the lifting plate.

[0011] By adopting the above technical solution, the guide rod can guide the lifting plate, thereby improving the stability of the lifting plate during movement and preventing the lifting plate from rotating.

[0012] Furthermore, the top of the fixed box is provided with a through groove, through which the rotating plate passes.

[0013] By adopting the above technical solution, the through slot design facilitates the smooth rotation of the rotating plate.

[0014] Furthermore, a collection box is placed on top of the base, and the collection box is located on one side of the fixed box.

[0015] By adopting the above technical solution, the collection box can collect the scraps, preventing the cut scraps from falling around the equipment.

[0016] Furthermore, a hydraulic cylinder is installed on the top of the support frame, and a movable plate is installed on the output end of the hydraulic cylinder via a piston rod, with a cutter installed on the bottom of the movable plate.

[0017] By adopting the above technical solution, when it is necessary to move the cutter downward, the hydraulic cylinder can be activated. The operation of the hydraulic cylinder can extend the piston rod, thereby driving the cutter downward, thus adjusting the position of the cutter.

[0018] Furthermore, a fixed frame is fixed inside the support frame, and a limiting groove is opened on one side of the fixed frame. A limiting block is set inside the limiting groove, and one side of the limiting block is fixedly connected to the movable plate.

[0019] By adopting the above technical solution, the movement of the movable plate can drive the limiting block to slide inside the limiting groove, thereby improving the stability of the movable plate when it moves.

[0020] Furthermore, the cutter and the movable plate are slidably connected to the limiting groove via a limiting block, and the cutter is located directly above the support plate.

[0021] By adopting the above technical solution, the pins on the support plate can be cut when the cutter moves down.

[0022] Furthermore, a fixed platform is installed on the other side of the top of the base. A sliding groove is opened on the top of the fixed platform, and a slide seat is provided inside the sliding groove. A second electric push rod is installed on one side of the fixed platform, and the output end of the second electric push rod is fixedly connected to one side of the slide seat through a piston rod. A frame is installed on the top of the slide seat, and a threaded shaft is threadedly connected to the frame. The bottom end of the threaded shaft is connected to a pressure plate through a bearing.

[0023] By adopting the above technical solution, when it is necessary to tighten the wire, the operator can rotate the threaded shaft to move the threaded shaft down and drive the pressure plate down, and the pressure plate can then tighten the wire.

[0024] Furthermore, a mounting plate is installed on the support frame, a first electric push rod is installed on the back of the mounting plate, and a calibration plate is installed on the output end of the first electric push rod via a piston rod.

[0025] By adopting the above technical solution, when the position of the calibration plate needs to be adjusted, the staff can activate the first electric push rod. The operation of the first electric push rod can cause the piston rod to retract, thereby driving the calibration plate to move.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model is equipped with a servo motor, worm gear, worm wheel, rotating shaft, screw hole, threaded column, and support plate. When the leads are cut, they will accumulate on the support plate. At this time, the hydraulic cylinder starts to move the cutter upward and reset, and at the same time, the servo motor is started. The servo motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the rotating shaft to rotate. When the rotating shaft rotates, it can drive the threaded column to move, which in turn drives the lifting plate to move upward, which in turn drives the rotating plate to rotate. The rotating plate can drive the support plate to rotate, thereby adjusting the tilt angle of the support plate so that the support plate tilts towards the collection box. At this time, the cut leads accumulated on the support plate will automatically slide into the collection box, avoiding the accidental bumping of the cutter when the staff manually picks up the residue, thereby reducing the frequency of manual contact with the cutting area, reducing the risk of safety accidents, and improving the safety of equipment use.

[0028] 2. This utility model is equipped with a guide rod to guide the lifting plate, thereby improving the stability of the lifting plate during movement and preventing the lifting plate from rotating. The through groove facilitates the smooth rotation of the rotating plate. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A lead-cutting device for processing wire assemblies, such as Figures 1-6 As shown, the system includes a base 1, a support frame 2 fixed to one side of the top of the base 1, a fixed box 12 installed on the top of the base 1, and a rotating shaft 13 connected to the lower part of the fixed box 12 via a bearing. A support plate 10 is installed on the upper side of one side of the fixed box 12 via a hinge 11. A screw hole 14 is opened inside the rotating shaft 13, and a threaded post 23 is threaded inside the screw hole 14. A lifting plate 18 is installed at the top of the threaded post 23. A rotating plate 19 is rotatably connected to the lifting plate 18 and the support plate 10 via a rotating shaft. A worm gear 15 is installed on the outer wall of the rotating shaft 13. A servo motor 17 is installed on the lower side of the other side of the fixed box 12, and a worm gear 16 is connected to the output end of the servo motor 17. When the rotating shaft 13 rotates, it can drive the threaded post 23 to move. The movement of the threaded post 23 can drive the lifting plate 18 to move, which in turn drives the rotating plate 19 to rotate. The rotating plate 19 can then drive the support plate 10 to rotate, thereby adjusting the tilt angle of the support plate 10.

[0040] See Figures 1-4 One end of the worm gear 16 is connected to the inner wall of the fixed box 12 through a bearing. The worm gear 16 meshes with the worm wheel 15. When the worm gear 16 rotates, it will drive the worm wheel 15 to rotate. The worm wheel 15 will drive the rotating shaft 13 to rotate, which in turn will drive the screw hole 14 to rotate. A through slot 21 is provided on the top of the fixed box 12. The rotating plate 19 passes through the through slot 21. The through slot 21 facilitates the smooth rotation of the rotating plate 19. A collection box 9 is also placed on the top of the base 1. The collection box 9 is located on one side of the fixed box 12. The collection box 9 can collect residual materials to prevent the cut-off residual materials from falling to the sides of the equipment.

[0041] Specifically, a hydraulic cylinder 3 is installed on the top of the support frame 2, and a movable plate 4 is installed on the output end of the hydraulic cylinder 3 through the piston rod. A cutter 5 is installed on the bottom of the movable plate 4. When the cutter 5 needs to be moved down, the hydraulic cylinder 3 can be activated. The operation of the hydraulic cylinder 3 can extend the piston rod, thereby driving the cutter 5 to move down, thus adjusting the position of the cutter 5. A fixed frame 6 is fixed inside the support frame 2. The cutter 5 and the movable plate 4 are slidably connected to the limiting groove 7 through the limiting block 8. The cutter 5 is located directly above the support plate 10 so that the pins on the support plate 10 can be cut when the cutter 5 moves down.

[0042] See Figures 1-4 A fixed platform 34 is installed on the other side of the top of the base 1. The top of the fixed platform 34 has a sliding groove 27, and a slide seat 28 is provided inside the sliding groove 27. A second electric push rod 29 is installed on one side of the fixed platform 34, and the output end of the second electric push rod 29 is fixedly connected to one side of the slide seat 28 through a piston rod. A frame 30 is installed on the top of the slide seat 28, and a threaded shaft 32 is threadedly connected to the frame 30. The bottom end of the threaded shaft 32 is connected to a pressure plate 31 through a bearing. A limiting rod 33 is installed on the top of the pressure plate 31, which can guide the pressure plate 31 and improve the stability of the pressure plate 31 when it moves. A silicone pad is provided at the bottom of the pressure plate 31. When it is necessary to tighten the wire, the operator can rotate the threaded shaft 32. A knob is connected to the top of the threaded shaft 32, and the outer wall of the knob is provided with The anti-slip texture causes the threaded shaft 32 to move downwards, which in turn moves the pressure plate 31 downwards. The pressure plate 31 can then press the wire tightly. A mounting plate 25 is installed on the support frame 2. A first electric push rod 26 is installed on the back of the mounting plate 25. A calibration plate 24 is installed at the output end of the first electric push rod 26 through a piston rod. When the position of the calibration plate 24 needs to be adjusted, the operator can start the first electric push rod 26. The operation of the first electric push rod 26 can retract the piston rod, thereby moving the calibration plate 24. A control panel 22 is installed on one side of the support frame 2. The control panel 22 is electrically connected to the hydraulic cylinder 3, the servo motor 17, the first electric push rod 26, and the second electric push rod 29, respectively. This allows the operator to start or stop the hydraulic cylinder 3, the servo motor 17, the first electric push rod 26, and the second electric push rod 29 through the control panel 22.

[0043] Example 2:

[0044] Based on the above embodiment 1, in order to prevent the lifting plate 18 from rotating, it needs to be guided, so the following structure will be set.

[0045] Specifically, a guide rod 20 is installed inside the upper part of the fixed box 12. The guide rod 20 passes through the lifting plate 18 and can guide the lifting plate 18, thereby improving the stability of the lifting plate 18 when it moves and preventing the lifting plate 18 from rotating.

[0046] Example 3:

[0047] Based on the above embodiment 1, in order to improve the stability of the movable plate 4 when it moves, it needs to be guided, so the following structure will be set.

[0048] See Figures 1-3 A limiting groove 7 is provided on one side of the fixed frame 6, and a limiting block 8 is provided inside the limiting groove 7. One side of the limiting block 8 is fixedly connected to the movable plate 4. The movement of the movable plate 4 can drive the limiting block 8 to slide inside the limiting groove 7, thereby improving the stability of the movable plate 4 when it moves.

[0049] The working principle of this utility model is as follows: First, before use, the operator turns on the power supply and places multiple wires on the slide 28 of the fixed platform 34. Then, the threaded shaft 32 is rotated to move the pressure plate 31 down and press the wires. Next, the second electric push rod 29 is activated to push the slide 28 along the slide groove 27 and then move the wires. Wires with excessively long leads will bend under the action of the calibration plate 24 until the lead cuts of all wires are in the same place. Then, the piston rod is driven to retract by the first electric push rod 26, which in turn moves the calibration plate 24 so that the calibration plate 24 does not contact the wires. At this time, the excess leads fall below the cutter 5. Then, the hydraulic cylinder 3 is activated by the control panel 22. The piston rod pushes the movable plate 4 to move the cutter 5 down. The limit block 8 slides along the limit groove 7 to ensure that the cutter 5 moves vertically. The cutter 5 completes the cutting of the wire leads above the support plate 10.

[0050] After cutting, the cutter 5 moves upward and resets; then the servo motor 17 is started to drive the worm gear 16 to rotate, the worm gear 16 drives the worm wheel 15 to rotate, the worm wheel 15 drives the rotating shaft 13 to rotate, the threaded hole 14 of the rotating shaft 13 cooperates with the threaded post 23 to make the lifting plate 18 move upward, the rotating plate 19 pushes the support plate 10 to rotate and tilt around the hinge 11, and the residual material slides down the support plate 10 to the collection box 9; after collection, the servo motor 17 reverses, and the support plate 10 is reset to horizontal.
