Description

Technical Field

[0001] The invention belongs to the technical field of wire harness stripping, and in particular relates to a circular cutting device for automobile wire harness processing. Background Art

[0002] In the automotive manufacturing industry, where high precision and efficiency are paramount, every detail counts. Automotive wiring harnesses, as a crucial component of a vehicle's electrical system, have a quality that directly impacts its overall performance and safety. However, the insulation layer on the outside of the wiring harness often needs to be precisely stripped during processing to facilitate subsequent wiring and connection. This is where automotive wire stripping machines become indispensable. These machines are mechanical devices specifically designed to efficiently strip the insulation layer from automotive wiring harnesses. These machines typically operate using a circular cutting method, using a specific tool or cutting device to create a uniform cut in the insulation layer of the wiring harness. Mechanical force is then used to strip the insulation away, exposing the underlying wires.

[0003] The problem with the existing technology is that the existing automotive wire harness stripping equipment often has great limitations in controlling the cutting depth, making it difficult to achieve precise cutting operations, and it is impossible to achieve synchronous adjustment of multiple cutting knives, resulting in low adjustment efficiency. Summary of the Invention

[0004] In response to the problems existing in the prior art, the present invention provides a circular cutting device for automobile wire harness processing, which has the advantages of high working efficiency, more precise cutting depth and high efficiency. It solves the problem that the existing automobile wire harness stripping equipment is difficult to achieve precise cutting operations, cannot achieve synchronous adjustment of multiple cutting knives, and has low adjustment efficiency.

[0005] The present invention is achieved as follows: a ring cutting device for automobile wire harness processing includes a mounting frame, a fixed ring frame and a first motor are fixedly connected to the mounting frame, a gear ring is rotatably connected to one side of the fixed ring frame, an output end of the first motor is fixedly connected to a first gear, the first gear is meshed with the gear ring, a connecting ring is fixedly connected to one side of the gear ring, a cutting mechanism is provided on the circumference of the connecting ring, and an adjustment mechanism is provided on one side of the cutting mechanism;

[0006] The cutting mechanism includes a movable frame, which is rotatably connected to the connecting ring. A third motor is fixedly installed on the movable frame, and a cutting knife is connected to one side of the third motor.

[0007] As a preferred embodiment of the present invention, a plurality of mounting grooves are provided on the circumference of the connecting ring, a fixed shaft is fixedly connected in the mounting groove, the fixed shaft is rotatably connected to the movable frame, and a movable groove is provided at one end of the movable frame away from the cutting knife.

[0008] As a preferred feature of the present invention, the third motor and one side of the cutting blade are coaxially connected to transmission wheels, each of which is protected by a transmission belt. In this device, the first motor on the mounting frame drives the first gear, which in turn rotates the meshing gear ring and the connecting ring attached to it. This transmission method ensures smooth and precise rotation of the connecting ring, providing a stable power source for subsequent cutting operations. Furthermore, the circumferential cutting mechanism on the connecting ring enables the device to achieve omnidirectional cutting of automotive wiring harnesses.

[0009] Secondly, a third motor in the cutting mechanism drives the cutting blades via a transmission belt. During this rotation, the cutting blades engage the automotive wiring harness, which rotates synchronously with the connecting ring, thereby stripping the wiring harness. Because the device utilizes multiple cutting blades operating simultaneously, it can simultaneously cut at multiple points on the automotive wiring harness. This not only greatly improves work efficiency but also ensures uniform and consistent cutting.

[0010] As a preferred embodiment of the present invention, the adjustment mechanism includes a rotating ring, which is rotatably sleeved on the connecting ring, and a plurality of shifting rods are fixedly connected to one side of the rotating ring, and the shifting rods movably pass through the movable slots.

[0011] As a preferred embodiment of the present invention, a tooth groove is provided on the rotating ring, and a second gear is meshedly connected to the tooth groove.

[0012] As a preferred embodiment of the present invention, a second motor is fixedly connected to the connecting ring, and an output end of the second motor is fixedly connected to the second gear.

[0013] As a preferred embodiment of the present invention, the fixed shaft includes a straight portion and a curved portion, and a notch is provided on the side of the upper end of the movable frame close to the gear ring; the movable frame can switch between the straight portion and the curved portion; and a yield groove is provided on the outer surface of the shift rod and / or the inner surface of the movable groove.

[0014] As a preferred embodiment of the present invention, the straight portion and the curved portion are connected in an arc shape, the diameter of the curved portion is 90%-95% of the diameter of the straight portion, and the angle between the straight portion and the curved portion is 3°-15°.

[0015] As a preferred embodiment of the present invention, the side of the gear ring is fixedly connected with an arc-shaped limiting slide, the rotating ring is fixedly connected with an electric push rod, the telescopic end of the electric push rod is fixedly connected with a roller, the roller is clamped in the arc-shaped limiting slide, and can roll along the arc-shaped limiting slide.

[0016] As a preferred embodiment of the present invention, an accommodating channel is provided inside the shift rod and the rotating ring, a supporting plate is fixedly connected to the outer side of the rotating ring, the main body of the electric push rod is fixedly connected to the supporting plate, and the electric push rod is at least partially located in the accommodating channel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By arranging multiple cutting blades around the circumference of the connecting ring, the present invention can simultaneously cut the automotive wiring harness at multiple points, improving work efficiency. By arranging the cutting blades on a movable frame and adjusting the tilt angle of the movable frame through an adjustment mechanism, the cutting depth can be gradually increased, making the cutting operation more precise and controllable.

[0019] 2. When the movable frame and the straight section are aligned, the position of the cutting mechanism can be adjusted to accommodate wire harnesses of varying diameters. When the rotating ring is pushed, causing the movable frame to slide from the straight section to the curved section, the frame rotates axially a certain angle, thereby tilting the cutting blade. This tilting of the cutting blade creates a spiral cut in the wire harness, facilitating stripping. For example, the movable frame and the straight section cooperate to perform a circular cut, followed by a spiral cut of the desired portion by the curved section. This facilitates stripping and also facilitates wire harness discharge (the wire harness can be ejected in a spiral motion). Furthermore, by pushing the rotating ring to shift the movable frame between the straight and curved sections, synchronization is ensured, ensuring that all cutting blade rings tilt synchronously at the same angle. The outer surface of the lever and / or the inner surface of the movable slot are provided with a relief groove (e.g., a wedge-shaped groove) to allow the movable frame to tilt.

[0034] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0035] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1 to 7 As shown, an embodiment of the present invention provides a ring cutting device for automobile wire harness processing, including a mounting frame 1, to which a fixed ring frame 4 and a first motor 5 are fixedly connected, a gear ring 7 is rotatably connected to one side of the fixed ring frame 4, an output end of the first motor 5 is fixedly connected to a first gear 6, the first gear 6 is meshed with the gear ring 7, a connecting ring 71 is fixedly connected to one side of the gear ring 7, a cutting mechanism 3 is arranged on the circumference of the connecting ring 71, and an adjusting mechanism 2 is arranged on one side of the cutting mechanism 3.

[0038] Furthermore, the cutting mechanism 3 includes a movable frame 31, which is rotatably connected to the connecting ring 71. A third motor 34 is fixedly installed on the movable frame 31, and a cutting knife 37 is connected to one side of the third motor 34. A plurality of mounting grooves 72 are provided on the circumference of the connecting ring 71. A fixed shaft 32 is fixedly connected in the mounting groove 72. The fixed shaft 32 is rotatably connected to the movable frame 31. A movable groove 33 is provided at one end of the movable frame 31 away from the cutting knife 37. The third motor 34 and one side of the cutting knife 37 are coaxially fixedly connected to a transmission wheel 35, and a transmission belt 36 is provided on the two transmission wheels 35.

[0039] Specifically, several movable frames 31 are circumferentially arranged on the connecting ring 71, and the cutting knife 37 is circumferentially arranged in the middle of the connecting ring 71. During operation, the cutting knife 37 is driven to rotate by starting the third motor 34, and the first gear 6 is driven to rotate by the first motor 5. The first gear 6 drives the gear ring 7 and the connecting ring 71 to rotate, thereby driving the several cutting knives 37 to rotate synchronously with the connecting ring 71, and can peel the automotive wiring harness placed inside the cutting knife 37. By setting up several cutting knives 37, cutting can be performed from multiple points of the automotive wiring harness at the same time, thereby improving work efficiency.

[0040] Furthermore, the adjusting mechanism 2 includes a rotating ring 21, which is rotatably sleeved on the connecting ring 71. A number of levers 25 are fixedly connected to one side of the rotating ring 21, and the levers 25 movably pass through the movable groove 33. A tooth groove 22 is provided on the rotating ring 21, and a second gear 24 is meshed and connected to the tooth groove 22. A second motor 23 is fixedly connected to the connecting ring 71, and the output end of the second motor 23 is fixedly connected to the second gear 24.

[0041] Specifically, the adjustment mechanism 2 can adjust the angle of the movable frame 31 to achieve cutting of wire harnesses of different specifications. In the initial state, the movable frame 31 is tilted, and the distance between the several cutting knives 37 is large. When the automobile wiring harness is placed inside the connecting ring 71, the second motor 23 is started to drive the second gear 24 to rotate. Through the engagement between the second gear 24 and the tooth groove 22, the rotating ring 21 drives the several shifting rods 25 to rotate. The shifting rods 25 move in the movable groove 33, and at the same time, the movable frame 31 is rotated with the fixed shaft 32 as the center axis, so that the cutting knife 37 gradually approaches the automobile wiring harness until it contacts the wiring harness. During the rotation of the connecting ring 71, the movable frame 31 continues to tilt and deepens the cutting depth until the outer layer of the wiring harness is cut off. The positions of multiple cutting knives 37 can be adjusted at the same time to achieve synchronous and efficient adjustment.

[0042] Example 2

[0043] On the basis of Example 1, the following settings are also performed:

[0044] See Figures 1-13The fixed shaft 32 includes a straight portion and a curved portion, and a notch is provided on the upper end of the movable frame 31 near the gear ring 7 (so that the thickness of the movable frame 31 is halved, allowing the movable frame 31 to move from the straight portion to the curved portion); the movable frame 31 can switch between the straight portion and the curved portion; the outer surface of the shift lever 25 and / or the inner surface of the movable groove 33 are provided with a clearance groove 8.

[0045] This setting has two functions:

[0046] When the movable frame 31 and the straight portion are matched, the working principle is the same as that of embodiment 1, and will not be described in detail here.

[0047] When the rotating ring 21 is pushed, causing the movable frame 31 to slide from the straight portion to the curved portion, the movable frame 31 rotates axially a certain angle, thereby tilting the cutting blade 37. This tilting of the cutting blade 37 creates a spiral cut in the wire harness, facilitating stripping (for example, the movable frame 31 first cuts in a circular pattern with the straight portion, and then cuts in a spiral pattern with the curved portion, thereby facilitating stripping). This also facilitates wire harness discharge (the wire harness can be ejected in a spiral motion). Furthermore, by pushing the rotating ring 21 to switch the movable frame 31 between the straight and curved portions, synchronization is ensured, allowing all cutting blades 37 to tilt synchronously at the same angle. The outer surface of the lever 25 and / or the inner surface of the movable slot 33 are provided with a clearance groove 8 (e.g., a wedge-shaped groove) to allow the movable frame 31 to tilt.

[0048] Furthermore, the straight portion and the curved portion are connected in an arc shape, and the diameter of the curved portion is 90%-95% of the diameter of the straight portion, which facilitates the passage of the movable frame 31; the angle between the straight portion and the curved portion is 3°-15°. If the angle is too large, it is not convenient for the movable frame 31 to switch between the two.

[0049] Furthermore, the side of the gear ring 7 is fixedly connected to an arc-shaped limiting slide 9, the rotating ring 21 is fixedly connected to an electric push rod 10, the telescopic end of the electric push rod 10 is fixedly connected to a roller 11, and the roller 11 is clamped in the arc-shaped limiting slide 9 and can roll along the arc-shaped limiting slide 9.

[0050] This arrangement has the following functions: the electric push rod 10 can slide, so it will not hinder the rotation of the rotating ring 21. And shortening the electric push rod 10 can make the rotating ring 21 push the movable frame 31 to switch from the straight part to the curved part, and vice versa.

[0051] Furthermore, an accommodating channel 12 is provided inside the shift rod 25 and the rotating ring 21, and a supporting plate 13 is fixedly connected to the outer side of the rotating ring 21. The main body of the electric push rod 10 is fixedly connected to the supporting plate 13, and the electric push rod 10 is at least partially located in the accommodating channel 12.

[0052] Through this arrangement, the accommodating channel 12 can limit the electric push rod 10 to prevent the electric push rod 10 from being bent, and the electric push rod 10 can be easily disassembled by removing the carrying plate 13.

[0053] Working principle of the present invention:

[0054] During use, the second motor 23 drives the second gear 24 and the rotating ring 21 to rotate, so that the movable frame 31 tilts, and the cutting knife 37 contacts the outer skin of the wire harness. The third motor 34 is started to drive the cutting knife 37 to rotate, and the first motor 5 is started to drive the first gear 6 and the gear ring 7 to rotate, and at the same time drive several movable frames 31 and the cutting knife 37 to rotate. The movable frame 31 continues to gradually tilt inward during the rotation process, so that the cutting depth is more accurate and controllable.

[0055] To sum up: this circular cutting device for automobile wiring harness processing, by arranging several cutting knives 37 on the circumference, can cut from multiple points of the automobile wiring harness at the same time, thereby improving work efficiency. By arranging the cutting knives 37 on the movable frame 31 and then adjusting the inclination angle of the movable frame 31 through the adjustment mechanism 2, the cutting depth can be slowly deepened, making the cutting operation more precise and controllable.
