Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a fast tool-changing wire harness cutting device. Background Art

[0002] A wire harness is a wire assembly that is composed of multiple wires or cables that are gathered together and wound with materials such as plastic or rubber and then fixed as a whole. It can be used to connect multiple devices and is an indispensable part of modern industry and transportation. In the production and processing of wire harnesses, it is necessary to use a cutting device to cut it into different lengths to suit different scenarios.

[0003] During the use of the current wire harness cutting device, the cutter used for cutting will reduce its blade sharpness due to factors such as wear during long-term use, and the cutter needs to be replaced. However, the current cutter is usually fixed with bolts, which is inconvenient to replace, resulting in long equipment downtime and a greater impact on production. For this reason, we propose a quick-change cutter wire harness cutting device. Utility Model Content

[0004] The utility model aims to provide a quick-change wire harness cutting device, which has the advantages of being able to quickly complete the replacement of the cutter, reducing the equipment downtime, extending the replacement cycle of the cutter, and reducing the impact on equipment downtime. It solves the problem that during the use of the current wire harness cutting device, the cutter used for cutting will reduce its blade sharpness due to factors such as wear during long-term use, and the cutter needs to be replaced, but the current cutter is usually fixed with bolts, which is inconvenient to replace, resulting in a long equipment downtime and a large impact on production.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-tool-changing wire harness cutting device, comprising a base and a cutter, a cylinder being fixedly mounted on the upper surface of the base through a fixing frame, a lifting plate being connected to the end of the cylinder output shaft, a through hole and a countersunk hole being respectively provided at the middle positions of the lifting plate and the front surface of the cutter, a T-shaped rod being inserted inside the through hole and the countersunk hole, an annular groove being provided on the outer surface of the T-shaped rod near the end position, a retaining spring being clamped inside the annular groove, blades being provided on the upper and lower surfaces of the cutter, grooves being symmetrically provided at both sides of the front surface of the lifting plate, springs being connected inside the two grooves, insertion rods being connected at the ends of the two springs, and fixing holes being symmetrically provided at both sides of the front surface of the cutter.

[0006] Preferably, two ends of the insertion rod are respectively located inside the fixing hole and the groove.

[0007] Preferably, slide grooves are symmetrically provided at both sides of the outer surface of the fixing frame, and protrusions are symmetrically provided at both sides of the outer surface of the lifting plate, and the two protrusions are respectively located in the two slide grooves.

[0008] Preferably, a placement groove is provided on the upper surface of the base below the cutting knife, and a knife seat is provided inside the placement groove.

[0009] Preferably, the upper surface of the base is symmetrically provided with grooves near both sides of the placement groove.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model can quickly replace the cutter by arranging a bottom plate, a lifting plate, a cylinder, a fixing frame, an elastic rod, an annular groove, a retaining spring, a countersunk hole, a through hole, a groove, a spring, an insertion rod and a fixing hole, thereby reducing the downtime of the equipment, extending the replacement cycle of the cutter, and reducing the effect of the downtime of the equipment. The cylinder drives the lifting plate and the cutter to rise and fall. When the cutter descends, the wire harness on the base is cut off by the blade. The cutter has two upper and lower blades. When the sharpness of one of the blades decreases and cannot be continued, the wire harness on the base is cut off by the blade. When continuing to cut the wire harness, press the plug rod to separate it from the fixing hole, and then rotate the cutter to interchange the positions of the upper and lower blades. After the interchange is completed, the elastic action of the spring allows the plug rod to be inserted into the fixing hole, thereby fixing the cutter, and the two blades can extend the replacement cycle of the cutter. When both blades cannot cut the wire harness due to reduced sharpness, remove the retaining spring inside the annular groove, and then pull out the T-bar from the through hole and the countersunk hole, the cutter can be removed and replaced with a new one.

[0012] 2. The utility model achieves the effect of improving the stability of the lifting plate by providing the slide groove and the protrusion. During the lifting process of the lifting plate, the protrusion slides inside the slide groove to limit the lifting plate, thereby improving the stability of the lifting plate.

[0013] 3. The utility model achieves the effect of facilitating the replacement of the knife seat by providing a placement groove and a knife seat. When the cutter cooperates with the knife seat to complete the wire harness cutting for a long time, certain dents will be generated on the surface of the knife seat. When there are too many dents on the knife seat, the knife seat can be directly removed from the placement groove and replaced with a new one. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 4 As shown, a quick tool-changing harness cutting device proposed by the utility model comprises a base 1 and a cutter 6. A cylinder 7 is fixedly mounted on the upper surface of the base 1 through a fixing frame 5. The fixing frame 5 is in an "n" shape. A lifting plate 14 is connected to the end of the output shaft of the cylinder 7. The lifting plate 14 is located below the cylinder 7 and inside the fixing frame 5. Slide grooves 8 are symmetrically arranged at both sides of the outer surface of the fixing frame 5. Bumps 9 are symmetrically arranged at both sides of the outer surface of the lifting plate 14, and the two bumps 9 are respectively located inside the two slide grooves 8. During the lifting and lowering process of the lifting plate 14, the bumps 9 slide inside the slide groove 8 to limit the lifting plate 14, thereby improving the stability of the lifting plate 14.

[0021] A through hole 18 and a countersunk hole 16 are respectively provided at the middle position of the front surface of the lifting plate 14 and the cutter 6, and a T-shaped rod 17 is inserted into the through hole 18 and the countersunk hole 16. An annular groove 13 is provided near the end position of the outer surface of the T-shaped rod 17, and a retaining spring 12 is clamped inside the annular groove 13. The cutter 6 is fixed to the front surface of the lifting plate 14 by the retaining spring 12, the through hole 18, the countersunk hole 16, the T-shaped rod 17 and the annular groove 13, and the cutter 6 can be rotated with the T-shaped rod 17 as the axis. A blade 15 is provided on the upper and lower surfaces of the cutter 6. When the cutter 6 rotates with the T-shaped rod 17 as the axis, the positions of the upper and lower blades 15 can be interchanged, thereby extending the replacement cycle of the cutter 6.

[0022] Grooves 10 are symmetrically provided at both sides of the front surface of the lifting plate 14, and springs 11 are connected inside the two grooves 10, and plug rods 20 are connected at the ends of the two springs 11. Fixing holes 19 are symmetrically provided at both sides of the front surface of the cutter 6, and the two ends of the plug rod 20 are respectively located inside the fixing holes 19 and the grooves 10. The plug rod 20 plays a role in limiting the rotation of the cutter 6. A placement groove 2 is provided on the upper surface of the base 1 below the cutter 6, and a knife seat 3 is provided inside the placement groove 2. In the process of the cutter 6 cooperating with the knife seat 3 to complete the wire harness cutting for a long time, certain dents will be generated on the surface of the knife seat 3. When there are too many dents on the knife seat 3, the knife seat 3 can be directly removed from the placement groove 2 and replaced with a new knife seat 3. Grooves 4 are symmetrically provided on the upper surface of the base 1 near both sides of the placement groove 2. The setting of the groove 4 facilitates the insertion of fingers and the removal of the knife seat 3.

[0023] When the utility model is in use, the cylinder 7 drives the lifting plate 14 and the cutter 6 to rise and fall. When the cutter 6 descends, the wire harness on the base 1 is cut off by the blade 15. The cutter 6 has two upper and lower blades 15. When the sharpness of one of the blades 15 decreases and it is unable to continue to cut the wire harness, the insertion rod 20 is pressed to separate it from the fixing hole 19, and then the cutter 6 is rotated so that the upper and lower blades 15 are interchanged. After the interchange is completed, the elastic action of the spring 11 causes the insertion rod 20 to be inserted into the fixing hole 19, thereby fixing the cutter 6, and the two blades 15 can extend the replacement cycle of the cutter 6. When both blades 15 cannot cut the wire harness due to the decrease in sharpness, the retaining spring 12 inside the annular groove 13 is removed, and then the T-bar 17 is pulled out from the through hole 18 and the countersunk hole 16, so that the cutter 6 can be removed and replaced with a new cutter 6.
