Description

Technical Field

[0001] This invention relates to the technical field of wire harness processing, and more specifically to a wire harness stripping device. Background Technology

[0002] In the manufacturing process of wire harnesses, the stripping of the insulation sheath at the wire harness ends is a fundamental and critical step. Its processing quality directly affects the reliability of subsequent terminal crimping and welding assembly, as well as the electrical performance and service life of the finished wire harness. With the continuous improvement of wire harness processing precision requirements, higher demands are placed on the cutting accuracy, core protection capability, and processing efficiency of stripping devices. Existing wire harness stripping equipment still has many shortcomings in practical applications: most devices use a cylinder to drive the stripping blade feed, making it difficult to accurately control the cutting depth. This can easily lead to excessive cutting depth, scratching or even cutting off part of the metal core, resulting in a decrease in the tensile strength and conductivity of the wire harness; or the cutting depth may be too shallow, resulting in incomplete cutting of the insulation layer, causing tearing and residual insulation during axial stripping. Furthermore, the adjustment for different wire diameters is cumbersome and has poor adaptability. Summary of the Invention

[0003] The purpose of this invention is to provide a wire harness stripping device to overcome the above-mentioned defects in the prior art.

[0004] A wire harness stripping device includes a frame, a clamping mechanism, and a stripping mechanism; The clamping mechanism is mounted on the frame and is used to clamp and fix the wire harness to be stripped. The peeling mechanism includes a first moving drive assembly, a second moving drive assembly, a rotary drive assembly, a cylinder, and a mounting plate. The first moving drive assembly is mounted on the frame and drives the first moving plate thereon to move. The second moving drive assembly is mounted on the first moving plate and drives the second moving plate thereon to move. The cylinder is rotatably connected to the first moving plate and driven by the rotary drive assembly. The second moving plate is rotatably connected to a drive shaft, and the end of the drive shaft is provided with a triangular plate. Two mounting plates are provided and symmetrically arranged in the cylinder. The outer end of the mounting plate is provided with a peeling blade. Several sliding rods inserted into the sliding grooves on the cylinder are symmetrically arranged on both sides of the mounting plate. Several springs are provided on the mounting plate and sleeved on the guide rods on the cylinder. Several rollers are rotatably connected to the inner end of the mounting plate. A swing frame that is slidably inserted into the mounting groove on the triangular plate is rotatably connected to the inner end of the mounting plate.

[0005] Furthermore, the clamping mechanism includes a clamping plate, a second spring, and a cylinder. The clamping plate has two connecting rods that are symmetrically and slidably connected to the frame. The second spring is sleeved on the connecting rod and located between the clamping plate and the frame. The side of the clamping plate has a connecting plate that is inserted into the upper limit block of the frame. The connecting plate has a rod that is inserted into the upper limit groove of the limit block. The end of the connecting plate is rotatably connected to a second roller. The cylinder is mounted on a fixed plate on the frame, and its piston rod has a triangular plate located between the two second rollers. The triangular plate is slidably connected to the fixed plate through a fixed rod.

[0006] Furthermore, the mobile drive assembly includes a drive screw and a motor. The drive screw is rotatably connected to the frame. The motor is mounted on the frame and a synchronous pulley is mounted on its output shaft. The synchronous pulley is connected to a synchronous pulley on the drive screw via a synchronous belt. The moving plate is slidably connected to a pull rod on the frame and screwed to the drive screw via a screw nut.

[0007] Furthermore, the second moving drive assembly includes a vertical plate, a second drive screw, and a second motor. The vertical plate is sleeved on the first drive screw and connected to the first pull rod. The second pull rod is provided between the first moving plate and the vertical plate. The second drive screw is rotatably connected between the first moving plate and the vertical plate. The second motor is mounted on the vertical plate, and a third synchronous wheel is mounted on its output shaft. The third synchronous wheel is connected to a fourth synchronous wheel on the second drive screw via a second synchronous belt. The second moving plate is screwed onto the second drive screw via a screw nut.

[0008] Furthermore, the rotary drive assembly includes a motor three, a gear one, and a gear two. The motor three is mounted on a movable plate one, and the gear one is mounted on the output shaft of the motor three. The gear one meshes with the gear two on the outside of the cylinder.

[0009] Furthermore, each mounting plate has two staggered stripping blades at its outer end.

[0010] Furthermore, the cylinder is provided with several positioning rods that are slidably inserted into the positioning grooves on the drive shaft.

[0011] Furthermore, the upper end of the clamping plate is provided with a V-shaped groove.

[0012] Furthermore, the fixing rods are provided in two and symmetrically arranged on both sides of the second triangular plate.

[0013] The beneficial effects achieved by this invention are as follows: 1. This application uses a mobile drive assembly two to drive the drive shaft and triangular plate one to move axially. Through the swing frame transmission and the elastic force of spring one, it can drive two mounting plates to feed synchronously along the slide groove of the cylinder, ensuring a smooth and uniform cutting process. A roller one is rotatably installed at the inner end of the mounting plate. After the cutting reaches the desired depth, the roller one abuts against the surface of the wire core to form a physical limit, precisely limiting the cutting depth of the stripper. This ensures that the insulation layer is completely cut off and structurally prevents the stripper from scratching the metal wire core, making it suitable for processing wire harnesses of various diameters. At the same time, two staggered strippers are set at the outer end of each mounting plate, forming a double-layer ring-cutting structure, which makes the cutting effect on the tough insulation layer more reliable and effectively prevents insulation residue and tearing problems.

[0014] 2. The first moving drive assembly of this device drives the entire peeling mechanism to translate along the first pull rod, completing the axial peeling of the insulation. The second moving drive assembly independently drives the radial feed of the peeling blade. The rotary drive assembly drives the cylinder to rotate through the meshing of gear one and gear two to achieve circumferential cutting. Each action has a clear division of labor and a compact layout. At the same time, the positioning rod inside the cylinder is slidably inserted into the positioning groove of the drive shaft, which ensures that the cylinder and the drive shaft rotate synchronously without interfering with their relative axial movement. There is no shaking during operation, the circumferential cutting trajectory is round and uniform, and the peeling quality is stable and reliable. Attached Figure Description

[0023] like Figure 1-5 As shown, the present invention provides a wire harness stripping device, including a frame 1, a clamping mechanism 2 and a stripping mechanism 3; Furthermore, the peeling mechanism 3 includes a first moving drive assembly 31, a second moving drive assembly 32, a rotary drive assembly 34, a cylinder 33, and a mounting plate 37. The first moving drive assembly 31 is mounted on the frame 1 and is used to drive the movement of the first moving plate 311 thereon. The first moving drive assembly 31 includes a first driving screw 312 and a first motor 313. The first driving screw 312 is rotatably connected to the frame 1. The first motor 313 is mounted on the frame 1 and a first synchronous pulley 314 is mounted on its output shaft. The first synchronous pulley 314 is connected to the second synchronous pulley 315 on the first driving screw 312 via a first synchronous belt 316. The first moving plate 311 is slidably connected to a first pull rod 317 on the frame 1 and is screwed to the first driving screw 312 via a screw nut. Additionally, the second moving drive assembly 32 is mounted on the first moving plate 311 and is used to drive the second moving plate 321 on it to move. The second moving drive assembly 32 includes a vertical plate 322, a second driving screw 323, and a second motor 324. The vertical plate 322 is sleeved on the first driving screw 312 and connected to a first pull rod 317. A second pull rod 328 is provided between the first moving plate 311 and the vertical plate 322. The second driving screw 323 is rotatably connected between the first moving plate 311 and the vertical plate 322. The second motor 324 is mounted on the vertical plate 322 and a third synchronous pulley 325 is mounted on its output shaft. The third synchronous pulley 325 is connected to a fourth synchronous pulley 327 on the second driving screw 323 through a second synchronous belt 326. The second moving plate 321 is screwed to the second driving screw 323 through a screw nut. However, the cylinder 33 is rotatably connected to the moving plate 311 and driven by the rotary drive assembly 34. The rotary drive assembly 34 includes a motor 341, a gear 342, and a gear 343. The motor 341 is mounted on the moving plate 311. The gear 342 is mounted on the output shaft of the motor 341. The gear 342 meshes with the gear 343 on the outside of the cylinder 33, thereby driving the cylinder 33 to rotate when stripping the wire harness. Furthermore, a drive shaft 35 is rotatably connected to the second movable plate 321. Several positioning rods are provided in the cylinder 33 and are slidably inserted into the positioning grooves on the drive shaft 35, thereby limiting the relative rotation between the drive shaft 35 and the cylinder 33, ensuring the phase alignment of the first triangular plate 36 and the mounting plate 37, and making the swing frame 38 drive reliably. The end of the drive shaft 35 is provided with the first triangular plate 36. Two mounting plates 37 are provided and symmetrically arranged in the cylinder 33. The outer end of each mounting plate 37 is provided with two staggered peeling blades 371. Several sliding rods 372 are symmetrically arranged on both sides of the mounting plate 37 and are inserted into the sliding grooves 331 on the cylinder 33. Several springs 373 are provided on the mounting plate 37 and sleeved on the guide rods 332 on the cylinder 33. Several rollers 374 are rotatably connected to the inner end of the mounting plate 37. The swing frame 38 is rotatably connected to the inner end of the mounting plate 37 and is slidably inserted into the mounting groove 361 on the first triangular plate 36.

[0024] In addition, the clamping mechanism 2 is mounted on the frame 1 and is used to clamp and fix the wire harness to be stripped. The clamping mechanism 2 includes a clamping plate 21, a spring 221 and a cylinder 26. The clamping plate 21 is provided with two connecting rods 22 that are symmetrically slidably connected to the frame 1. The upper end of the clamping plate 21 is provided with a V-shaped groove. When clamping, the V-shaped groove at the upper end of the clamping plate 21 automatically guides the wire harness to the center position, realizing self-centering clamping. A spring 221 is sleeved on the connecting rod 22 and located between the clamping plate 21 and the frame 1. A connecting plate 24 is provided on the side of the clamping plate 21 and inserted into the upper limit block 23 of the frame 1. A rod 241 is provided on the connecting plate 24 and inserted into the upper limit groove 231 of the limit block 23. A roller 25 is rotatably connected to the end of the connecting plate 24. The cylinder 26 is mounted on the fixing plate 261 on the frame 1 and a triangular plate 27 is provided on its piston rod between the two rollers 25. The triangular plate 27 is slidably connected to the fixing plate 261 through the fixing rod 271. There are two fixing rods 271 and they are symmetrically arranged on both sides of the triangular plate 27. The two symmetrically arranged fixing rods 271 make the force on the triangular plate 27 balanced during the movement, avoid deflection, and ensure that the triangular plate 27 is always pushed vertically between the two rollers 25.

[0025] Detailed implementation methods and principles: During operation, the piston rod of cylinder 26 extends, the triangular plate 27 presses against the two rollers 25, the two clamping plates 21 move on the connecting rod 22, the spring 221 on the connecting rod 22 is compressed, and the V-groove at the upper end of the clamping plate 21 opens to its maximum, waiting for the wire harness to be inserted. The first moving drive assembly 31 drives the first moving plate 311 to the initial position close to the clamping mechanism 2; the second moving drive assembly 32 drives the second moving plate 321 to the initial position close to the cylinder 33; the first triangular plate 36 moves forward synchronously with the drive shaft 35; the first spring 373 is in a compressed state, pushing the two mounting plates 37 to open radially outward; the spacing between the peeling blades 371 at the outer end of the mounting plates 37 is the largest. Insert the end of the wire harness to be stripped from the center of the cylinder 33, through the gap between the two mounting plates 37, and extend it between the V-grooves of the two clamping plates 21 of the clamping mechanism 2. Adjust the extension position of the wire harness according to the preset stripping length. When cylinder 26 is activated, the piston rod retracts, pushing the inclined surfaces on both sides of triangle plate 27 away from roller 25. Under the elastic force of spring 221, roller 25 drives connecting plate 24 to move towards the center along the limiting groove 231 of limiting block 23, pushing two clamping plates 21 to slide along connecting rod 22. The wire harness is automatically centered and clamped through the V-groove at the upper end, completing the fixation of the wire harness and preventing the wire harness from shifting during stripping. When motor 2 324 operates, it drives drive screw 2 323 to rotate through synchronous pulley 3 325, synchronous belt 2 326, and synchronous pulley 4 327, which in turn drives moving plate 2 321 to move along pull rod 2 328, and drives drive shaft 35 and end triangle plate 1 36 to move synchronously. When the triangular plate 36 moves backward, the sliding rod 372 on the mounting plate 37 moves in the sliding groove 331 through the swing frame 38. Under the elastic force of the spring 373 on the guide rod 332 inside the cylinder 33, the stripper 371 at the outer end of the mounting plate 37 gradually approaches and cuts into the insulation layer of the wire harness. When motor 341 starts, it drives gear 1 342 on the output shaft to rotate. Through gear meshing, gear 2 343 on the outside of cylinder 33 is driven to rotate cylinder 33 around its own axis. When the cylinder 33 rotates, it synchronously drives the mounting plate 37, the stripper 371, and the swing frame 38 to make a circular motion around the wire harness axis. The stripper 371 cuts the insulation layer along the circular trajectory, completing the full circle cut and completely cutting off the insulation skin to be stripped from the wire harness body. Then, motor 313 starts, and drives drive screw 312 to rotate through synchronous pulley 314, synchronous belt 316, and synchronous pulley 315, driving moving plate 311 to move away from clamping mechanism 2 along pull rod 317. The moving plate 311 drives the cylinder 33, the mounting plate 37, and the stripper 371 to move as a whole. Since the stripper 371 has been inserted into the circumferential cutting opening, it will drive the cut insulation to move backward together, completely peeling the insulation from the metal wire core and completing the axial stripping action. After the stripping is completed, the second moving drive component 32 rotates in reverse, the first triangular plate 36 pushes the swing frame 38 radially, the two mounting plates 37 slide outwards to reset, and the stripping blade 371 opens accordingly, separating the wire harness from the stripped insulation sheath. The piston rod of cylinder 26 of clamping mechanism 2 extends, driving triangular plate 27 to push roller 25, causing clamping plate 21 to move to both sides on connecting rod 22, releasing the processed wire harness, and the operator can take out the finished product; Once fully restored to its initial state, it awaits the clamping of the next wire harness and begins the next work cycle.
