Description

Technical Field

[0001] This utility model relates to the field of ground wire cutting technology, and more specifically, to a ground wire cutting device. Background Technology

[0002] refer to Figure 1 Ground wires 42 are provided on both sides of the high-speed wiring harness 4. After the high-speed wiring harness 4 is produced, the unused ground wires 42 will be cut off according to the needs of later use. Currently, when cutting the ground wires 42, the excess ground wires 42 are cut off by a cutting machine. Because the ground wires 42 are cut from the middle, the other end of the ground wires 42 is short and small. After the ground wires 42 are cut off, the cut ground wires 42 are easy to scatter on the machine and are not easy to clean later. At the same time, when cutting the ground wires 42, the cutting of the ground wires 42 is easy to scratch the surface of the high-speed wiring harness 4, which will affect the subsequent use of the high-speed wiring harness 4.

[0003] The purpose of this invention is to provide a ground wire cutting device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a ground wire cutting device, including a base plate. A displacement member is disposed on the upper side of the base plate, and a bottom receiving device and a cutting device are disposed on the upper side of the displacement member. The bottom receiving device and the cutting device cut off the ground wire at one end of a high-speed wiring harness. The bottom receiving device includes a sliding plate, with two sliding rods symmetrically fixed to the upper side of the sliding plate. A sliding plate is disposed on the upper side of the sliding plate, and the sliding plate is slidably fitted onto the sliding rods near both ends. A driving member is disposed on the lower side of the sliding plate to drive the sliding plate to move up and down. A bearing wire is fixedly connected to the upper side of the sliding plate via a fixing plate. The device comprises a block, wherein the driving component drives the receiving block to move upward to receive several high-speed wire harnesses, and the cutting device includes a lower pressure plate, with sliding rods fixed at the four upper corners of the lower pressure plate. A movable plate is provided on the upper side of the lower pressure plate and is slidably mounted on the sliding rods. Several cutting rods are fixed on the movable plate by fixing strips. An upper wire block is fixed on the lower side of the lower pressure plate and is positioned directly above the receiving block. Several pressure rods are provided between the lower pressure plate and the upper wire block. The pressure rods and cutting rods are staggered. The pressure rods move the ground wire away from the high-speed wire harness, and the cutting rods cut the ground wire.

[0005] As a further improvement to this technical solution, the driving component includes a lifting frame fixed to the bottom of the sliding plate, with rollers rotatably connected to the bottom of the lifting frame. A track frame is fixed to the upper side of the sliding plate, and a push plate is slidably arranged inside the track frame. The push plate is located below the rollers, and a cylinder is fixed to the end of the track frame away from the sliding plate. One end of the piston rod of the cylinder is fixedly connected to the push plate. The upper side of the push plate away from the cylinder is set as a downward inclined surface. When the cylinder pushes the push plate to move closer to the sliding plate in the track frame, the inclined surface of the push plate pushes the rollers upward, causing the rollers to drive the sliding plate upward.

[0006] As a further improvement to this technical solution, tension springs are fixed at both ends of the sliding plate, and the other end of the tension springs is fixed to the side wall of the slide plate. When the push plate moves toward the cylinder, the tension springs drive the sliding plate to move downward.

[0007] As a further improvement to this technical solution, a top plate is fixed to the upper end of the two slide rods, and the tangent device also includes a push cylinder fixed to the upper side of the slide rod. One end of the piston rod of the push cylinder passes through the slide rod and is fixedly connected to the upper side wall of the moving plate.

[0008] As a further improvement to this technical solution, two guide rods are symmetrically fixed on the lower pressure plate. The upper end of the guide rod slides through the moving plate, and the lower end of the guide rod slides through the fixed plate and the sliding plate.

[0009] As a further improvement to this technical solution, a number of push springs are installed between the moving plate and the lower pressure plate. The push springs push the lower pressure plate away from the moving plate. A rubber block is sleeved on the sliding rod at a position between the moving plate and the lower pressure plate. The height of the rubber block is less than the distance between the moving plate and the lower pressure plate.

[0010] As a further improvement to this technical solution, the moving plate, the lower pressure plate, and the upper line block are all provided with a number of cutting rod grooves that are adapted to the shape of the cutting rod, and one end of the cutting rod is slidably inserted into the cutting rod groove.

[0011] As a further improvement to this technical solution, the upper block is provided with a number of pressure rod grooves that are adapted to the shape of the pressure rod. The pressure rod is slidably disposed in the pressure rod grooves, and a push spring is fixed at the upper end of the pressure rod. A spring groove is provided at the position corresponding to the pressure rod groove on the lower pressure plate. The push spring is installed in the spring groove and pushes the pressure rod to move away from the lower pressure plate.

[0012] As a further improvement to this technical solution, a wire pressing groove adapted to the shape of the high-speed wire harness is provided at the middle position of the lower end of the pressure rod, and wire guide surfaces inclined towards the wire pressing groove are provided on both sides of the lower end of the pressure rod. The wire guide surfaces guide the ground wire away from the high-speed wire harness. Downward extending guide blocks are provided at both ends of the cutting rod near the edge, and the cutting rod cuts the ground wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this ground wire cutting device, the drive unit drives the wire receiving block to move upward, so that the wire receiving block receives several high-speed wire harnesses, ensuring that the high-speed wire harnesses are not in a suspended state. Then, the piston rod of the push cylinder pushes the moving plate downward. At this time, the downward movement of the upper wire block and the cooperation of the wire receiving block fix the position of the high-speed wire harness. During the downward movement of the upper wire block, the high-speed wire harness enters the wire pressing groove, and the conductor surface guides the ground wires located on both sides of the high-speed wire harness away from the high-speed wire harness, so that the ground wires present an outward bulging structure. Then the cutting rod cuts the ground wires, thereby achieving the effect of not cutting the surface of the high-speed wire harness.

[0014] 2. In this ground wire cutting device, a rubber sleeve is fitted on one end of the high-speed wire harness. The rubber sleeve wraps around one end of the ground wire. After the ground wire is cut, the rubber sleeve fixes the cut end of the ground wire. After the high-speed wire harness completes the ground wire cutting, the rubber sleeve and the ground wire are manually removed to prevent the small ground wire from falling onto the machine.

[0019] Example 1 Please see Figure 1 As shown, this embodiment provides a high-speed wire harness 4. Two ground wires 42 are provided at both ends of the high-speed wire harness 4. In this solution, a rubber sleeve 41 made of soft rubber is sleeved on one end of the high-speed wire harness 4, and the other end of the ground wire 42 is fixed in the rubber sleeve 41.

[0020] refer to Figures 2-12 As shown, this solution provides a ground wire cutting device, including a base plate 1. A displacement member is provided on the upper side of the base plate 1. A bottom receiving device 2 and a wire cutting device 3 are provided on the upper side of the displacement member. The bottom receiving device 2 and the wire cutting device 3 cut off the ground wire 42 at one end of the high-speed wire harness 4. The displacement member includes two sliding rails 11 fixed on the upper side of the base plate 1. A servo motor 12 fixed on the base plate 1 is provided between the two sliding rails 11. One end of the output shaft of the servo motor 12 is fixed to a lead screw through a coupling. The two ends of the lead screw are rotatably set on the base plate 1. A lead screw nut is threadedly connected to the lead screw. The bottom receiving device 2 includes a sliding plate 21. The lead screw nut is fixed on the lower side of the sliding plate 21. When the servo motor 12 is powered on, the servo motor 12 can drive the lead screw to rotate. The rotating lead screw drives the lead screw nut to move the sliding plate 21. At the same time, the bottom of the sliding plate 21 and the sliding rail 11 are slidably set, and the sliding rail 11 supports the sliding plate 21.

[0021] Two sliding rods 28 are symmetrically fixed to the upper side of the slide plate 21. The two sliding rods 28 are vertically arranged. A sliding plate 25 is provided on the upper side of the slide plate 21. The sliding plate 25 is slidably sleeved on the sliding rods 28 near both ends. A driving component for driving the sliding plate 25 to move up and down is provided on the lower side of the sliding plate 25. The driving component includes a lifting frame 24 fixed to the bottom of the sliding plate 25. Rollers are rollably connected to the bottom of the lifting frame 24. A track frame 22 is fixed on the upper side of the slide plate 21. The track frame 22 is located below the rollers. A push plate 23 is slidably arranged inside the track frame 22. The push plate 23 is located below the rollers. A cylinder 211 is fixed to the end of the track frame 22 away from the sliding plate 25. One end of the piston rod of the cylinder 211 is fixedly connected to the push plate 23. The upper side of the push plate 23 away from the cylinder 211 is tilted downward. The inclined plane has a roller that rolls in contact with it. When the cylinder 211 pushes the push plate 23 to move closer to the sliding plate 25 in the track frame 22, the inclined plane of the push plate 23 pushes the roller upward, causing the roller to move the sliding plate 25 upward. When the cylinder 211 drives the push plate 23 to move away from the sliding plate 25, the roller rolls along the inclined plane, and the sliding plate 25 moves downward. To ensure that the roller and the push plate 23 are always in contact, tension springs are fixed at both ends of the sliding plate 25. The other end of the tension spring is fixed to the side wall of the slide plate 21. When the sliding plate 25 moves upward, the tension spring is stretched. When the push plate 23 moves closer to the cylinder 211, the tension spring contracts, causing the sliding plate 25 to move downward. During this process, the tension spring on the sliding plate 25 keeps the roller in contact with the inclined plane.

[0022] The tangent device 3 includes a lower pressure plate 32, with sliding rods 33 fixed at each of the four upper corners of the lower pressure plate 32. A movable plate 31 is provided on the upper side of the lower pressure plate 32, and the movable plate 31 is slidably mounted on the sliding rods 33. A nut is fixed to the end of the sliding rod 33, blocking the movable plate 31 and limiting its movement distance. Several push springs 311 are installed between the movable plate 31 and the lower pressure plate 32, pushing the lower pressure plate 32 away from the movable plate 31. At this time, several push springs 311 push the moving plate 31 away from the lower pressure plate 32, so that one side of the moving plate 31 contacts the end cap. At the same time, a rubber block 312 is sleeved on the sliding rod 33 at the position between the moving plate 31 and the lower pressure plate 32. The height of the rubber block 312 is less than the distance between the moving plate 31 and the lower pressure plate 32. That is to say, when the moving plate 31 moves, it will be blocked by the rubber block 312, so that the moving plate 31 can only move a limited distance on the sliding rod 33.

[0023] A top plate 29 is fixed to the upper end of the two slide rods 28. The tangent device 3 also includes a downward push cylinder 38 fixed to the upper side of the slide rod 28. One end of the piston rod of the downward push cylinder 38 passes through the slide rod 28 and is fixedly connected to the upper side wall of the moving plate 31. When the piston rod of the downward push cylinder 38 extends downward, the moving plate 31 moves downward along with one end of the piston rod of the downward push cylinder 38.

[0024] A wire-bearing block 27 is fixedly connected to the upper side of the sliding plate 25 via a fixing plate 26. The fixing plate 26 is also fixed on the sliding plate 25. The driving component drives the wire-bearing block 27 to move upward to receive several high-speed wire harnesses 4. An upper wire block 34 is fixed to the lower side of the lower pressure plate 32. The upper wire block 34 is located directly above the wire-bearing block 27. Several wire grooves for placing high-speed wire harnesses 4 are opened on the wire-bearing block 27. Several pressure blocks corresponding to the wire grooves are fixed to the lower side of the upper wire block 34. During the process of the wire-bearing block 27 moving upward and the upper wire block 34 moving downward, the wire-bearing block 27 and the upper wire block 34 clamp and fix the position of the high-speed wire harnesses 4.

[0025] Two guide rods 35 are symmetrically fixed on the lower pressure plate 32. The upper end of the guide rod 35 slides through the moving plate 31, and the lower end of the guide rod 35 slides through the fixed plate 26 and the sliding plate 25. When the lower cylinder 38 drives the moving plate 31 to move down, one end of the guide rod 35 slides between the fixed plate 26 and the sliding plate 25 to ensure the stability of the moving plate 31 and the lower pressure plate 32 in moving up and down, and to ensure that the wire receiving block 27 and the upper wire block 34 can be accurately connected to position the high-speed wire harness 4.

[0026] Several cutting rods 36 are fixed on the movable plate 31 by a fixing strip 313. The cutting rods 36 are vertically arranged, and each cutting rod 36 has a locking slot at both ends. Several slots corresponding to the locking positions of the cutting rods 36 are formed on the fixing strip 313. Each slot forms a locking block. The locking block is set in the locking slot between two connected cutting rods 36. The position of the cutting rod 36 is fixed by the locking block. At the same time, several cutting rod grooves 341 that are adapted to the shape of the cutting rods 36 are formed on the movable plate 31, the lower pressure plate 32, and the upper wire block 34. One end of the cutting rod 36 is slidably inserted into the cutting rod groove 341. At this time, the cutting rod 36 is fixed on the movable plate 31. The cutting rod 36 slides inside the cutting rod groove 341 in the lower pressure plate 32 and the upper wire block 34. The lower end of the cutting rod 36 extends through to the lower side of the upper wire block 34.

[0027] Several pressure rods 37 are arranged between the lower pressure plate 32 and the upper wire block 34. The pressure rods 37 are arranged vertically. Several pressure rod grooves 342 that are adapted to the shape of the pressure rods 37 are opened on the upper wire block 34. The pressure rods 37 are slidably arranged in the pressure rod grooves 342. A stop block larger than the pressure rod groove 342 is provided at the upper end of the pressure rod 37. The stop block prevents the pressure rod 37 from sliding down from the pressure rod groove 342. A push spring 371 is fixed at the upper end of the pressure rod 37. A spring groove is opened at the corresponding position of the lower pressure plate 32 and the pressure rod groove 342. The push spring 371 is installed in the spring groove. The push spring 371 pushes the pressure rod 37 to move away from the lower pressure plate 32. One end of the pressure rod 37 extends through to the bottom of the upper wire block 34.

[0028] like Figure 11 As shown, several pressure rods 37 and several cutting rods 36 are arranged alternately, and there is an overlapping area when the pressure rods 37 and cutting rods 36 are alternately arranged. A pressure groove adapted to the shape of the high-speed wire harness 4 is opened at the middle position of the lower end of the pressure rod 37. A conductor surface inclined towards the pressure groove is provided on both sides of the lower end of the pressure rod 37. The conductor surface guides the ground wire 42 away from the high-speed wire harness 4. Both ends of the cutting rod 36 are provided with downward extending guide blocks near the edge. The pressure rod 37 drives the ground wire 42 away from the high-speed wire harness 4, and the cutting rod 36 cuts the ground wire 42.

[0029] Meanwhile, spaces are provided on the upper side of the conductor block 27 and the lower middle part of the upper conductor block 34 for the cutting rod 36 and the pressing rod 37 to handle the ground wire 42 of the high-speed wire harness 4, and reference is made to Figure 12 As shown, the lower end of the pressure bar 37 is located below the lower end of the cutting bar 36.

[0030] When using this device: In the initial state, one end of several high-speed wire harnesses 4 is suspended on the upper side of the base plate 1 by external clamps. At this time, the bottom receiving device 2 and the wire cutting device 3 are located on one side of the high-speed wire harness 4. The bottom receiving device 2 and the wire cutting device 3 are driven to approach the high-speed wire harness 4 by the displacement member. When the bottom receiving device 2 and the wire cutting device 3 move to the designated position, the displacement member stops driving the bottom receiving device 2 and the wire cutting device 3 to move. At this time, one end of the high-speed wire harness 4 is between the wire receiving block 27 and the upper wire block 34. Then the piston rod of the cylinder 211 extends to drive the push plate 23 to move. The moving push plate 23 pushes the roller to move upward. The moving roller drives the wire receiving block 27 to move upward, so that the wire receiving block 27 receives the high-speed wire harness 4 from the lower side. Each high-speed wire harness 4 is placed in the corresponding wire groove. Then the piston rod of the downward-pushing cylinder 38 extends to drive the moving plate 31 to move downward. The moving plate 31 drives the lower pressure plate 32 to move downward. The lower pressure plate 32 drives the guide rod 35 to move downward. The guide rod 35 slides on the sliding plate 25 and the fixed plate 26. The guide rod 35 restricts the downward trajectory of the lower pressure plate 32, ensuring that the upper wire block 34 can accurately press the high-speed wire harness 4 in the wire receiving block 27.

[0031] As the upper wire block 34 approaches the receiving block 27, one end of the pressure rod 37 first contacts the high-speed wire harness 4, and the high-speed wire harness 4 enters the wire pressing groove. The side wall of the pressure rod 37 is between the high-speed wire harness 4 and the ground wire 42. The conductor surface moves the ground wire 42 away from the high-speed wire harness 4. At this time, the ground wire 42 bulges outward. Then the upper wire block 34 continues to move. At this time, the downward spring 371 is compressed and contracts, while the pressure rod 37 presses the high-speed wire harness 4 onto the receiving block 27. The upper wire block 34 continues to move downward, making... The upper wire block 34 presses the high-speed wire harness 4 onto the wire support block 27. At this time, the cutting rod 36 is in contact with the ground wire 42. Because the upper wire block 34 is blocked by the wire support block 27, the moving plate 31 continues to move downward. The moving plate 31 drives the cutting rod 36 to move downward, so that the cutting rod 36 cuts the ground wire 42. After the cutting rod 36 cuts the ground wire 42, the rubber blocks 312 block the moving plate 31 to prevent the moving plate 31 from driving the cutting rod 36 to collide with the bottom of the wire support block 27 and damage the cutting rod 36. At this time, the ground wire 42 that has been cut is fixed by the rubber sleeve 41, so that the ground wire 42 will not come off the material. After the cutting operation is completed, the wire cutting device 3 moves up and the bottom receiving device 2 moves down, so that the bottom receiving device 2 and the wire cutting device 3 release the fixation of the high-speed wire harness 4. Then the worker takes away the high-speed wire harness 4 and pulls the rubber sleeve 41 off the high-speed wire harness 4.

[0032] The drive unit drives the wire receiving block 27 to move upward, allowing it to receive several high-speed wire harnesses 4 and ensuring that the high-speed wire harnesses 4 are not suspended. Then, the piston rod of the downward-pushing cylinder 38 pushes the moving plate 31 downward. At this time, the downward movement of the upper wire block 34, in conjunction with the wire receiving block 27, fixes the position of the high-speed wire harnesses 4. During the downward movement of the upper wire block 34, the high-speed wire harnesses 4 enter the wire pressing groove, and the conductor surface guides the ground wires 42 located on both sides of the high-speed wire harnesses 4 away from the high-speed wire harnesses 4, so that... The ground wire 42 has an outward bulging structure. Then the cutting rod 36 cuts the ground wire 42 to avoid damaging the surface of the high-speed wire harness 4. A rubber sleeve 41 is put on one end of the high-speed wire harness 4 to wrap one end of the ground wire 42. After the ground wire 42 is cut, the rubber sleeve 41 fixes the cut end of the ground wire 42. After the high-speed wire harness 4 has finished cutting the ground wire 42, the rubber sleeve 41 and the ground wire 42 are removed manually to prevent the small ground wire 42 from falling onto the machine.
