Description

Technical Field

[0001] This utility model belongs to the technical field of wire harness processing equipment, specifically, it relates to an equidistant cutting device for wire harness assembly. Background Technology

[0002] A wiring harness is a general unit of service equipment for a certain load source group, such as trunk lines, switching devices, and control systems. The basic research content of traffic theory is to study the relationship between traffic volume, call loss, and wiring harness capacity. Therefore, the wiring harness is an important basic concept in traffic theory.

[0003] Chinese Patent Publication No. CN206296400U discloses an equidistant cutting device for wire harness assembly, including a base plate, a bracket, a top plate, a first motor, a disc, a fixing plate, a wire sleeve, a first slide rail, a first slider, and a first button. Initially, the thumb cylinder is open, and the first slider is at the rightmost end of the slide rail. During cutting, one end of the wire harness is first passed through the wire sleeve, and the thumb cylinder clamps it. Then, two motors are started. The first motor drives the first slider to move left and right, allowing the wire harness to move with it. The second motor drives the blade to move up and down. When the first slider touches the first button, the pressure plate presses down on the wire harness, and the blade cuts the wire harness. Once the thumb cylinder releases, the first slider and blade reset. When the second button is pressed, the thumb cylinder clamps the wire again, repeating the cutting action. This allows for batch cutting with consistent lengths. When there are enough wire harnesses on the mounting plate, the first slider is at the far right, shutting off the device to collect and bundle the wire harnesses. However, this device may not be suitable for wire harnesses with special materials, shapes, or diameters. For example, the thumb cylinder may not be able to clamp the wire harnesses firmly if they are hard or thick, resulting in inaccurate cutting lengths. Or, for soft and easily deformable wire harnesses, twisting or tangling may occur during the wire passing through the wire sleeve and cutting process, affecting the cutting quality.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an equidistant cutting device for wire harness assembly, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A wire harness assembly equidistant cutting device includes: a base, a support frame connected to the right side of the base surface, a wire harness reel connected to the support frame, a support mechanism connected to the left side of the base surface, a wire guide roller connected to the support mechanism, a wire guide groove formed on the surface of the wire guide roller, clamps connected to both sides of the wire guide groove on the surface of the wire guide roller, and the clamps being threadedly connected to the surface of the wire guide roller; a cutting mechanism is also connected to the base surface, the cutting mechanism including a cutting table connected to the base surface, a fixing frame connected to the surface of the cutting table, a cylinder connected to the bottom end of the fixing frame, and a cutting blade connected to the bottom end of the cylinder.

[0008] Optionally, the support mechanism includes a first support plate and a second support plate, with the guide roller located between the first support plate and the second support plate.

[0013] Optionally, the cutting table is located below the guide roller, and the surface of the cutting table is provided with a scale groove.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up clamping plates, the clamping plates on the guide roller are threadedly connected to the surface of the guide roller. The spacing can be flexibly adjusted by rotating the clamping plates, thereby adapting to wire harnesses of different diameters. Whether the wire harness is thin or thick, it can be stably clamped on the guide roller, ensuring that the device can handle wire harnesses of various specifications and improving its applicability.

[0016] 2. With the addition of protrusions, the silicone protrusions on the opposite side of the clamping plate have the same width as the wire groove.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Please see Figure 1-6As shown, this embodiment provides an equidistant cutting device for wire harness assembly, including: a base 1, a support frame 2 connected to the right side of the base 1, a wire harness disc 3 connected to the support frame 2, a support mechanism connected to the left side of the base 1, a wire guide roller 8 connected to the support mechanism, a wire guide groove 81 opened on the surface of the wire guide roller 8, clamping plates 6 connected to both the front and rear sides of the wire guide groove 81 on the surface of the wire guide roller 8, and the clamping plates 6 are threadedly connected to the surface of the wire guide roller 8, and a cutting mechanism is also connected to the surface of the base 1, the cutting mechanism including a cutting table 9 connected to the surface of the base 1, a fixing frame 10 connected to the surface of the cutting table 9, a cylinder 12 connected to the bottom end of the fixing frame 10, and a cutting blade 13 connected to the bottom end of the cylinder 12.

[0032] The support frame 2 connected to the right side of the base 1 supports the wire harness reel 3, which holds the coiled wire harness. Before cutting begins, the wire harness coil is mounted on the reel 3 for subsequent feeding and cutting operations. The support mechanism connected to the left side of the base 1 supports the wire guide roller 8. The wire guide roller 8 has a wire guide groove 81 on its surface, which guides the wire harness and keeps it on a specific path during feeding, preventing deviation or tangling. Clamping plates 6 are connected to both sides of the wire guide groove 81 on the surface of the wire guide roller 8, and the clamping plates 6 are threaded to the surface of the wire guide roller 8. By rotating the clamping plates 6, the spacing between the clamping plates 6 can be adjusted to accommodate wire harnesses of different diameters. When it is necessary to clamp a thinner wire harness, the clamping plates 6 can be tightened to bring them closer together; if the wire harness is thinner... If the wire harness is too thick, loosen the clamping plate 6 to widen the gap and ensure that the wire harness can be stably clamped on the wire roller 8. The cutting table 9 is connected to the surface of the base 1 and is the working platform for wire harness cutting. The fixing frame 10 is connected to the surface of the cutting table 9 and is used to fix the cylinder 12 to ensure the stability of the cylinder 12 during operation. The cylinder 12 is connected to the bottom of the fixing frame 10. When the cylinder 12 is started, its telescopic rod will extend downward, driving the cutting blade 13 connected to the bottom to move downward. During the descent, the cutting blade 13 can cut the wire harness placed on the cutting table 9, thereby achieving the purpose of cutting the wire harness at equal intervals according to a certain length requirement. By controlling the extension frequency of the cylinder 12 and the stroke of each descent, the cutting interval distance can be precisely controlled to meet the needs of wire harnesses of different lengths during the wire harness assembly process.

[0033] In this embodiment, the support mechanism includes a first support plate 4 and a second support plate 5. The guide roller 8 is located between the first support plate 4 and the second support plate 5. A limiting groove 51 is formed on the surface of the second support plate 5. The second support plate 5 is provided with a driving mechanism at the limiting groove 51. The driving mechanism includes a turntable 7 that is rotatably connected to the limiting groove 51. A motor 11 is connected to the rear end of the turntable 7. One end of the guide roller 8 is fixedly connected to the turntable 7, and the other end is rotatably connected to the first support plate 4.

[0034] The support mechanism consists of a first support plate 4 and a second support plate 5, with the wire guide roller 8 positioned between them. This structure provides stable support for the wire guide roller 8, ensuring that it does not shake or shift during operation and guaranteeing the stability of the wire harness delivery. A limiting groove 51 is formed on the surface of the second support plate 5, and the drive mechanism is located at this limiting groove 51. The drive mechanism includes a turntable 7 rotatably connected to the limiting groove 51. The rear end of the turntable 7 is connected to a motor 11, which serves as a power source. When the motor 11 starts running, it drives the turntable 7 to rotate within the limiting groove 51. One end of the wire guide roller 8 is fixedly connected to the turntable 7, and the other end is rotatably connected to the first support plate 4. When the turntable 7 rotates under the drive of the motor 11, it synchronously drives the wire guide roller 8 to rotate. The rotation of the wire guide roller 8 realizes the delivery of the wire harness. By controlling the speed and direction of rotation of the motor 11, the delivery speed and delivery amount of the wire harness can be precisely controlled to meet different cutting requirements.

[0035] Both clamping plates 6 have protrusions on their opposite sides. The width of these protrusions is the same as the width of the wire guide groove 81, and the protrusions are made of silicone. The fact that the width of the protrusions is the same as the width of the wire guide groove 81 allows the protrusions to fit precisely into the wire guide groove 81, thus more accurately fixing the wire harness. When the clamping plates 6 are tightened, the protrusions can tightly clamp the wire harness from both sides, preventing the wire harness from shifting within the wire guide groove 81 during transport. This improves the stability of wire harness transport and the accuracy of cutting. The silicone material of the protrusions has good flexibility and friction. Good flexibility can avoid damaging the surface of the wire harness when clamping it, especially for some soft or easily damaged wire harnesses. The greater friction can better fix the wire harness, ensuring that the wire harness will not slip between the wire harness and the protrusions when the wire guide roller 8 rotates to transport the wire harness, thus ensuring the reliability of wire harness transport.

[0036] The cutting table 9 is located below the wire guide roller 8, ensuring that the wire harness conveyed from the wire guide roller 8 can fall directly onto the cutting table 9, facilitating the cutting operation of the cutting blade 13 without the need for additional wire harness transfer steps, thus improving cutting efficiency. The surface of the cutting table 9 is provided with graduated grooves, which can be used as measuring tools to accurately measure the length of the wire harness on the cutting table 9. When cutting the wire harness, the operator can accurately control the length of each cut according to the markings in the graduated grooves, achieving equidistant cutting of the wire harness. This meets the strict requirements for wire harnesses of different lengths during the wire harness assembly process, improving cutting accuracy and production quality.

[0037] Working principle:

[0038] First, the coiled wire harness is placed on the wire harness reel 3, which is supported by the support frame 2 on the right side of the base 1 to ensure the stability of the wire harness during subsequent conveying. The spacing of the clamping plates 6, which are threaded to the front and rear sides of the wire groove 81 on the rotating wire guide roller 8, is adjusted according to the diameter of the wire harness. If the wire harness is thin, the clamping plates 6 are tightened to reduce the spacing; if the wire harness is thick, the clamping plates 6 are loosened to increase the spacing. In this way, the silicone protrusions on the clamping plates 6, which are the same width as the wire groove 81, can tightly clamp the wire harness, ensuring that the wire harness does not slip and avoiding damage to the surface of the wire harness.

[0039] Then, the motor 11 in the drive mechanism is started. The motor 11 drives the turntable 7 connected to it to rotate in the limiting groove 51 of the second support plate 5. Since one end of the wire roller 8 is fixedly connected to the turntable 7 and the other end is rotatably connected to the first support plate 4, the rotation of the turntable 7 synchronously drives the wire roller 8 to rotate. The wire groove 81 on the surface of the wire roller 8 guides the wire bundle so that it moves along a specific path during the conveying process, avoiding deviation or entanglement. By controlling the speed and rotation direction of the motor 11, the conveying speed and conveying amount of the wire bundle can be precisely controlled to meet different cutting requirements.

[0040] Finally, the wire harness conveyed from the guide roller 8 falls directly onto the cutting table 9 located below it. The graduated grooves on the surface of the cutting table 9 can help the operator accurately measure the length of the wire harness. According to the required wire harness length, the equidistant cutting of the wire harness is achieved by controlling the extension and retraction frequency and each descent stroke of the cylinder 12. When the cylinder 12 is activated, its extension rod extends downward, driving the cutting blade 13 at the bottom to descend and cut the wire harness placed on the cutting table 9. After the cutting is completed, the extension rod of the cylinder 12 retracts, and the cutting blade 13 rises to reset, waiting for the next cutting command. At the same time, the guide roller 8 continues to rotate and convey the wire harness, repeating the above cutting process to achieve continuous equidistant cutting operation, meeting the requirements of wire harness assembly for different lengths of wire harness.
