Description

Technical Field

[0001] This utility model mainly relates to the field of wire harness processing technology, specifically a cutting fixture for wire harness processing. Background Technology

[0002] Wire harnesses are widely used in current industrial production. They are wiring components that connect various electrical devices in a circuit. They consist of an insulating sheath, terminals, and wires. The wires in the wire harnesses produced in the workshop are very long, so they need to be cut according to different applications.

[0003] The existing method of conveying wire harnesses in their entirety requires the use of conveyor rollers for compression. While the conveyor rollers can provide a certain amount of pressure to compress and restrict the wire harness, the wire harness may break at the moment of cutting, posing a safety hazard. In addition, after the wire harness is cut, when the subsequent conveyor rollers transport the wire harness and connect it with the previous conveyor rollers, there will be a misalignment, causing the entire wire harness transported in the subsequent transport to tilt. As a result, when the wire harness is cut again, the cut surface of the wire harness will be tilted. Utility Model Content

[0004] This utility model provides a solution that addresses the problem of overly simplistic solutions in existing technologies. It offers a significantly different solution, primarily a cutting fixture for wire harness processing. This fixture solves the problems mentioned in the background section, such as wire harness breakage and erratic movement when cut by simply squeezing and restricting the wire harness with a conveyor roller. Additionally, it addresses the issue that when the cut wire harness is conveyed and connected to the forward conveyor roller, misalignment occurs, resulting in slanted cut surfaces when subsequent wire harnesses are cut.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A cutting fixture for wire harness processing includes a base, a support seat on the base, a conveying roller for conveying the wire harness on the support seat, a processing table on the support seat, a guiding component for guiding and restricting the wire harness on the processing table, a cutting blade for cutting the wire harness on the support seat, and a pressing component for fixing both sides of the cutting point of the wire harness on the cutting blade.

[0007] Preferably, the support base is provided with two layers of conveying rollers, and the support base is provided with positioning holes.

[0008] Preferably, the guiding component includes a guiding block, which is disposed on a processing table. The processing table has a guiding groove and a cutting groove.

[0009] Preferably, the processing table is provided with a bracket, the bracket is provided with a first limiting rod, the guide block is provided with a first support block, the first support block is sleeved on the first limiting rod, and the first limiting rod is sleeved with a first spring.

[0010] Preferably, the support base is provided with a support frame, the support frame is provided with a hydraulic cylinder, and the hydraulic cylinder telescopic rod is provided with a cutting blade.

[0011] Preferably, the pressing component includes a second limiting rod, which is disposed on the cutting blade. A second spring is sleeved on the second limiting rod, and a second support block is sleeved on the second limiting rod. A connecting rod is disposed on the second support block, and a pressure block is disposed at the end of the connecting rod away from the second support block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a guiding component, when the wire harness is transported to the bottom of the cutting blade, the guiding component will guide the wire harness to prevent the wire harness from deviating and causing the cut surface to tilt. When the cutting blade descends to cut the wire harness, the pressing component will first press down on the guiding component to press down and fix both sides of the wire harness cutting point. This can prevent the wire harness from breaking after cutting. At the same time, since the two ends of the wire harness are pressed down and fixed, the two wire harnesses still maintain the state before cutting after cutting. When transported again, the wire harness can be transported in a straight line without deviation.

[0013] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please refer to the appendix carefully. Figures 1-5 A cutting fixture for wire harness processing includes a base 1, a support seat 2 on the base 1, a conveying roller 4 for conveying the wire harness on the support seat 2, a processing table 5 on the support seat 2, a guiding component for guiding and restricting the wire harness on the processing table 5, a cutting blade 9 on the support seat 2 for cutting the wire harness, and a pressing component on the cutting blade 9 for fixing both sides of the cutting point of the wire harness.

[0025] The specific operating procedure of this utility is as follows: The wire harness is passed through one end of the support base 2 and transported to the other end of the support base 2 via the conveyor roller 4. During the transportation, the wire harness will pass through the guide component on the processing table 5. The guide component keeps the wire harness transported in a straight line. The guide component is set on both sides of the cutting blade 9. There is no cutting component in the part directly below the cutting blade 9. When the cutting blade 9 is lowered, the cutting blade 9 will drive the pressing component to descend synchronously. The pressing component will press down on the guide component. The guide component presses down and fixes the two sides of the wire harness cutting point. The cutting blade 9 continues to descend and cuts the wire harness. After cutting, the cutting blade 9 and the pressing component rise, and the wire harness continues to be transported via the conveyor roller 4. Due to the setting of the guide component, the two wire harnesses continue to be transported in a straight line.

[0026] Please refer to Figure 1 and Figure 2 The support base 2 is equipped with two layers of conveying rollers 4, and the support base 2 is provided with positioning holes 3.

[0027] Positioning holes 3 are provided on both sides of the support base 2, and the positioning holes 3 are aligned with the gap between the two layers of conveying rollers 4. The conveying rollers 4 are set on both sides of the processing table 5. The wire harness is inserted through the positioning hole 3 on one side of the support base 2 and inserted between the two layers of conveying rollers 4. The wire harness is moved forward by the rotation of the conveying roller 4. The wire harness passes through the processing table 5 and is inserted into the other side of the conveying roller 4. It is transported to the other end of the support base 2 by the other side of the conveying roller 4 and output from the positioning hole 3 at the other end of the support base 2.

[0028] Please refer to Figure 3 and Figure 4 The guiding component includes a guiding block 10, which is disposed on a processing table 5. The processing table 5 has a guiding groove 6 and a cutting groove 20. A bracket 12 is disposed on the processing table 5. A first limiting rod 13 is disposed on the bracket 12. A first support block 11 is disposed on the guiding block 10. The first support block 11 is sleeved on the first limiting rod 13. A first spring 14 is sleeved on the first limiting rod 13.

[0029] The guide block 10 is attached to the wire harness by pushing the first support block 11 down by the first spring 14. Due to the elasticity of the first spring 14, the guide block 10 can adapt to wire harnesses of different thicknesses. The first limiting rod 13 is used to support and limit the first spring 14 and the first support block 11. The guide groove 6 is arc-shaped, and the guide block 10 is also arc-shaped. The guide groove 6 and the guide block 10 are used to limit the guide wire harness to keep it moving in a straight line.

[0030] Please refer to Figure 3 and Figure 5A support frame 7 is provided on the support base 2, a hydraulic cylinder 8 is provided on the support frame 7, a cutting blade 9 is provided on the telescopic rod of the hydraulic cylinder 8, and the pressing component includes a second limiting rod 16, which is provided on the cutting blade 9. A second spring 17 is sleeved on the second limiting rod 16, a second support block 15 is sleeved on the second limiting rod 16, a connecting rod 18 is provided on the second support block 15, and a pressure block 19 is provided at the end of the connecting rod 18 away from the second support block 15.

[0031] Hydraulic cylinder 8 is activated. The hydraulic cylinder 8 extends and retracts via a hydraulic rod, causing the cutting blade 9 to descend. Simultaneously, the descent of the cutting blade 9 causes the pressure block 19 to descend as well. The pressure block 19 presses down on the guide blocks 10 on both sides, thus fixing the wire harness cutting point on both sides. As the cutting blade 9 continues to descend, the pressure block 19 can no longer press down. At this point, the pressure block 19 pushes the second support block 15 upward via the connecting rod 18. The second support block 15 moves upward in a straight line along the second limiting rod 16, compressing the second spring 17. As the second spring 17 is continuously compressed, the pressure of the pressure block 19 on the guide blocks 10 increases. When the cutting blade 9 descends into the cutting groove 20, the pressure of the second spring 17 reaches its maximum, and the cutting blade 9 cuts the wire harness. The cutting groove 20 is used to restrict the cutting blade 9 to maintain a straight line when cutting the wire harness. The pressure blocks 19 at both ends press down on the guide blocks 10 to ensure that the wire harness cutting point on both sides is fixed, preventing the wire harness from breaking during cutting.

[0032] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
