Description

Technical Field

[0001] The present invention belongs to the technical field related to peeling devices, and specifically discloses an automatic cutting and peeling device for electrical wire harnesses. Background Art

[0002] When wiring an electrical cabinet, it is necessary to peel the wire harnesses inside. The existing peeling tools are laborious to operate. After manually cutting a small section of the wire harness, the outer skins of both ends of a small section of the cable are cut and peeled. However, this peeling method has many defects, such as low peeling efficiency. When multiple wire harnesses need to be peeled, the labor intensity is large, it is laborious to peel, and the labor cost is increased.

[0003] When using some automated wire stripping devices, they cannot operate quickly inside the cabinet, and the operating space and the position of the wire harness cannot be well utilized, resulting in low wiring efficiency. Therefore, we need to improve this situation. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background art, and a proposed automatic cutting and peeling device for electrical wire harnesses includes a base. On both sides of the upper end surface of the base, side frames are vertically installed. A moving rod is slidably installed inside the two side frames. On both sides of the lower end surface of the moving rod, lifting components are provided. On one outer wall of the moving rod, multiple mounting rods are provided. At the ends of the multiple mounting rods away from the moving rod, ring frames are fixedly provided. On the outer surface of each ring frame, a baffle is fixedly provided. Inside each ring frame, a peeling cylinder is provided. Inside each peeling cylinder, a peeling and wire tightening component is provided.

[0005] The peeling and wire tightening component is located near the lower part of the inner wall of the peeling cylinder, and is used to peel the epidermis at the lower end of the wire harness and can tighten the loose wire cores after peeling.

[0006] Preferably, the lifting component includes a lifting cylinder. The telescopic end of the lifting cylinder is connected to the lower end surface of the moving rod, and the bottom of the lifting cylinder is fixedly provided on the upper end surface of the base.

[0007] Preferably, the peeling and wire tightening component includes angle plates respectively installed on the inner walls of both sides of the peeling cylinder. Inside both angle plates, a swinging pressing component is provided. A clamping ring is sleeved outside the peeling cylinder, and the clamping ring is rotationally matched with the ring frame. A synchronous pulley is sleeved outside the peeling cylinder and below the clamping ring.

[0008] Preferably, the swinging pressing component includes a rotating shaft fixedly provided in the middle of the inside of the angle plate. A rotating sleeve is rotatably sleeved outside the rotating shaft. Below the outer side of the rotating sleeve, a peeling arc knife is fixedly provided. An active component is provided on the outer wall of the peeling arc knife and near the zigzag part.

[0009] Preferably, the movable part includes a telescopic cylinder. The telescopic end of the telescopic cylinder abuts against the outer wall of the peeling arc knife and near the bending part. An installation shell is rotatably installed at one end of the telescopic cylinder away from the peeling arc knife. The installation shell is fixedly embedded inside the peeling cylinder. A skin abutting part is arranged on the lower end surface of the peeling arc knife.

[0010] Preferably, the skin abutting part includes connecting rods fixedly installed on both sides of the lower end surface of the peeling arc knife. An arc-shaped ring is jointly arranged at the ends of the two connecting rods. A rotating ring is rotatably sleeved in the middle of the outer side of the arc-shaped ring. Friction rings are equidistantly sleeved on the outer side of the rotating ring along an arc track.

[0011] Preferably, wing frames are arranged on both sides of the peeling arc knife. Shafts are rotatably installed inside the two wing frames. Support rods are fixedly arranged on the outer sides of the two shafts. Rotating joints are arranged on the outer walls of the two support rods close to each other. And movable cylinders are movably sleeved outside the two rotating joints. Ball bearings are installed on the outer sides of the two movable cylinders away from the support rods. A bidirectional telescopic rod is jointly arranged between the two ball bearings. Core abutting parts are arranged at the ends of the two support rods away from the shafts.

[0012] Preferably, the core abutting part includes a core abutting rod. Connecting shafts are inserted into both ends of the core abutting rod. One end of one of the connecting shafts penetrates below the other end and into the inside of the support rod. The core abutting rod is rotatably attached to the upper end surface of the support rod. Reel wheels are rotatably arranged on the upper and lower ends of the outer sides of the two connecting shafts.

[0013] Preferably, drive belts are jointly arranged outside the multiple synchronous wheels. A drive wheel is rotatably arranged at one end inside the drive belt. A plug shaft is fixedly inserted into the middle of the drive wheel. A motor is fixedly arranged on the upper end surface of the plug shaft. The motor is fixed to the outer wall of one side of the moving rod through a fixedly arranged mounting bracket on the outer side of one side of the motor. Feet are arranged on both sides of the lower end surface of the base. Reinforcing plates are symmetrically arranged on the outer walls of the two side frames. A U-shaped rod is jointly arranged outside the two reinforcing plates. A clamping rod is jointly arranged at the lower ends of the multiple baffle plates. A recycling box is clamped outside the clamping rod. And the recycling box is located below the multiple peeling cylinders.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Place the device at the inner bottom of the electrical cabinet body. The peeling cylinder corresponds to the corresponding connected wire harness. As the telescopic end of the lifting cylinder rises, the moving rod, the mounting rod, and the peeling cylinder penetrate into the outside of the wire harness. The telescopic cylinders on both sides inside the peeling cylinder correspondingly drive the peeling arc knife to press against the outside of the wire harness. The synchronous wheels outside the peeling cylinder are driven by the drive wheel and the drive belt to rotate by themselves inside the ring frame. Then, with the gradual pressing of the telescopic cylinder, the outer skin of the wire harness is peeled off.

[0016] 2. When peeling, the two swivels located below the peeling arc knife will press against the epidermis peeled off from the lower end. As the telescopic end of the lifting cylinder moves downward, the pressed epidermis breaks away from the surface of the wire core and moves downward, thus separating the peeled epidermis from the wire core. Without the clamping of the wire core, the epidermis falls into the recycling bin for temporary storage and collection.

[0017] 3. The wire core with the wire skin peeled off will open outward. At this time, under the drive of the bidirectional telescopic rod, the two support rods above the outside of the peeling arc knife move closer to each other, causing the pressing rod and the wire winding wheel at one end of the support rod to fit against the upper end of the wire harness. When the wire harness is pulled out, the wire winding wheel will press against both sides of the wire harness and wrap around the wire core on the outside of the wire core. Similarly, driving the conveyor belt to rotate again causes the wire winding wheel to rotate on the outside of the wire core and tighten the slightly opened wire core. Thus, it is more convenient for later wire connection and insertion, improving the efficiency of later wire harness connection. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0032] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0033] As Figures 1 - 12 shown, an automatic cutting and peeling device for electrical wire harnesses includes a base 1. On both sides of the upper end surface of the base 1, side frames 2 are vertically installed. A moving rod 11 is slidably installed inside the two side frames 2. Lifting members are provided on both sides of the lower end surface of the moving rod 11. On one outer wall of the moving rod 11, a plurality of mounting rods 12 are provided. At the ends of the plurality of mounting rods 12 away from the moving rod 11, ring frames 13 are fixedly provided. On the outer surface of each ring frame 13, a baffle 7 is fixedly provided. Inside each ring frame 13, a peeling cylinder 5 is provided. Inside each peeling cylinder 5, a peeling and wire tightening assembly is provided;

[0034] The peeling and wire tightening assembly is located on the inner wall of the peeling cylinder 5 and near the lower part, and is used for peeling the epidermis at the lower end of the wire harness and tightening the loose wire cores after peeling.

[0035] The lifting member includes a lifting cylinder 10. The telescopic end of the lifting cylinder 10 is connected to the lower end surface of the moving rod 11, and the bottom of the lifting cylinder 10 is fixedly provided on the upper end surface of the base 1;

[0036] The lifting cylinder 10 can drive the moving rod 11 to move up and down, so as to cooperate with subsequent use.

[0037] The stripping and tensioning assembly includes angle plates 20 respectively installed on the inner walls of both sides of the stripping cylinder 5. Swing pressing assemblies are arranged inside both angle plates 20. A snap ring 21 is sleeved outside the stripping cylinder 5. The snap ring 21 is rotatably matched with the ring frame 13. A synchronous pulley 19 is sleeved outside the stripping cylinder 5 and below the snap ring 21.

[0038] The rotation mode between the snap ring 21 and the ring frame 13 is embedded rotation. The lower end of the snap ring 21 is embedded inside the ring frame 13. Therefore, when the ring frame 13 moves up and down, the stripping cylinder 5 also moves accordingly.

[0039] The swing pressing assembly includes a rotating shaft 29 fixedly arranged in the middle inside the angle plate 20. A rotating sleeve 23 is rotatably sleeved outside the rotating shaft 29. A stripping arc knife 25 is fixedly arranged below the outside of the rotating sleeve 23. An active part is arranged on the outer wall of the stripping arc knife 25 and near the bending part.

[0040] The rotating shaft 29 and the rotating sleeve 23 can be pressed by the active part to make the stripping arc knife 25 flip and move back and forth.

[0041] The active part includes a telescopic cylinder 27. The telescopic end of the telescopic cylinder 27 abuts against the outer wall of the stripping arc knife 25 and near the bending part. One end of the telescopic cylinder 27 away from the stripping arc knife 25 is rotatably installed with a mounting shell 22. The mounting shell 22 is fixedly embedded inside the stripping cylinder 5. A skin pressing part is arranged on the lower end face of the stripping arc knife 25.

[0042] The mounting shell 22 is used to assemble the telescopic cylinder 27 inside the lower part of the stripping cylinder 5. Under the telescopic pressing of the telescopic cylinder 27, it will cause the stripping arc knife 25 to rotate outside the rotating shaft 29. During stripping, the distance between the two stripping arc knives 25 can be adjusted, so that the two stripping arc knives 25 gradually penetrate into the cable during circumferential cutting, thereby achieving the purpose of stripping.

[0043] The stripping arc knife 25 is composed of a swing rod in the shape of an L, and an arc-shaped cutting edge is arranged at the lower end.

[0044] The skin pressing part includes connecting rods 36 fixedly installed on both sides of the lower end face of the stripping arc knife 25. An arc ring 35 is jointly arranged at the ends of the two connecting rods 36. A rotating ring 37 is rotatably sleeved in the middle outside the arc ring 35. Friction rings 28 are sleeved on the outside of the rotating ring 37 at equal distances along an arc track.

[0045] The arc ring 35 can assist the friction rings 28 and the rotating ring 37 to closely adhere to the epidermis of the wire harness. It should be emphasized that the friction rings 28, the arc ring 35, and the rotating ring 37 are all made of flexible materials. When the stripping arc knife 25 cuts off the epidermis at the lower end of the wire harness, during the downward movement of the telescopic end of the lifting cylinder 10, the friction rings 28 are pressed against the epidermis, so as to rub off the peeled epidermis from the lower end of the wire core.

[0046] Both sides of the peeling arc knife 25 are provided with wing frames 24. Inside each of the two wing frames 24, a clamping shaft 30 is rotatably installed, and a support rod 26 is fixedly arranged on the outer side of each of the two clamping shafts 30;

[0047] The wing frames 24 and the clamping shafts 30 are rotation support structures arranged to cooperate with the support rods 26 to rotate on the peeling arc knife 25. The purpose is to enable the support rods 26 to perform the subsequent function of tightening the wire core above the peeling arc knife 25. On the outer walls of the mutually approaching sides of the two support rods 26, rotating joints 31 are arranged, and movable cylinders 33 are movably sleeved outside the two rotating joints 31. On the outer sides of the ends of the two movable cylinders 33 away from the support rods 26, balls 34 are installed. A double telescopic rod 32 is arranged between the two balls 34. Inside the ends of the two support rods 26 away from the clamping shafts 30, core abutting members are arranged;

[0048] The rotating joint 31 is composed of a spherical body and a rod structure. The movable cylinder 33 is sleeved outside the rotating joint 31. Driven by the double telescopic rod 32, the two support rods 26 rotate, causing the movable cylinder 33 to move outside the rotating joint 31. Cooperating with the balls 34 at the telescopic ends of the double telescopic rod 32, it is beneficial for the two support rods 26 to rotate more flexibly.

[0049] The core abutting member includes an abutting rod 40. Connecting shafts 38 are inserted through the two ends of the abutting rod 40. One end of one of the connecting shafts 38 penetrates downward to the inside of the support rod 26. The abutting rod 40 is rotatably attached to the upper end face of the support rod 26. Winding wheels 39 are rotatably arranged on the outer sides of the upper and lower ends of the two connecting shafts 38;

[0050] The abutting rod 40 can be finely adjusted and rotated above the support rod 26 under the connection of the connecting shaft 38 correspondingly inserted into the support rod 26, so that the four winding wheels 39 can be more flexible during wrapping. When the four winding wheels 39 symmetrically wrap the wire core at the lower end of the wire harness, they can cooperate with the rotation of the peeling cylinder 5 to tighten the slightly opened wire core after peeling, so as to be more convenient for subsequent wire harness connection.

[0051] A drive belt 8 is arranged outside a plurality of synchronous wheels 19. One end inside the drive belt 8 is rotatably provided with a drive wheel 18. An insertion shaft 16 is fixedly inserted through the middle of the drive wheel 18. On the upper end face of the insertion shaft 16, a motor 17 is fixedly arranged. One side of the motor 17 is fixedly installed on the outer wall of one side of the moving rod 11 through a fixedly arranged mounting bracket 15;

[0052] The drive belt 8 is a common drive chain in the market. Driven by the rotation of the motor 17, the drive wheel 18 corresponding to the lower end of the insertion shaft 16 can drive a plurality of peeling cylinders 5 to rotate by themselves;

[0053] On both sides of the lower end surface of the base 1, feet 9 are provided. On the outer walls of the two side frames 2, reinforcing plates 3 are symmetrically arranged together. On the outer sides of the two reinforcing plates 3, a U-shaped rod 4 is provided. At the lower ends of multiple baffles 7, a clamping rod 14 is provided together. The outside of the clamping rod 14 is clamped with a recycling box 6, and the recycling box 6 is located below multiple peeling cylinders 5;

[0054] When the two reinforcing plates 3 and the U-shaped rod 4 are in use, it is convenient for workers to adjust the positions of the base 1 and the side frames 2 externally, and thus it is more convenient to operate externally during use;

[0055] The recycling box 6 can be assembled by being inserted into the outside of the clamping rod 14 from above, so that the recycling box 6 can hold the peeled epidermis below the peeling cylinders 5.

[0056] Working principle: When in use, the device needs to be placed inside the electrical cabinet body. The feet 9 at the lower ends of both sides of the base 1 are placed at the bottom of the cabinet body. Then the worker arranges the wire harnesses to be peeled in sequence inside the peeling cylinders 5. As the lifting member ascends, the peeling arc knives 25 inside the peeling cylinders 5 are placed on the lower surface of the wire harness. Under the pressing of the telescopic cylinder 27, the two peeling arc knives 25 are attached to the outer surface of the wire harness from both sides. The motor 17 drives the insertion shaft 16 and the driving wheel 18 to rotate, prompting the transmission belt 8 to drive the synchronous wheels 19 outside the multiple peeling cylinders 5 to rotate. At the same time, the telescopic cylinder 27 also prompts the peeling arc knives 25 to press against the epidermis of the wire harness during the rotation process, so as to cut off the epidermis at the lower end of the wire harness by rotation. At this time, the two connecting rods 36 at the lower ends of the peeling arc knives 25 also drive multiple friction rings 28 to press against the outer surface of the peeled epidermis. Under the pressing of the multiple friction rings 28, as the telescopic end of the lifting cylinder 10 moves downward, the peeled epidermis is pulled downward, causing the epidermis to fall into the internal temporary collection of the lower recycling box 6. At this time, the wire cores of the peeled epidermis are exposed outside. The bidirectional telescopic rod 32 drives the movable cylinders 33 at both ends to approach each other, causing the two support rods 26 to approach each other. The corresponding pressing rods 40 and the wire winding wheels 39 are wrapped around the slightly opened wire cores, and the slightly opened wire cores are looped. Then the transmission belt 8 is driven to rotate again, so that the peeling cylinders 5 rotate, and the wire winding wheels 39 rotate and adhere to the outside of the slightly opened wire cores and tighten them. Thus, the peeled wire harness will be more worry-free during plug-in installation, saving the steps for workers to tighten and wind the wire cores in sequence, and adding convenience to the subsequent connection of the wire harness.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
