Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production, in particular to a wire harness production cutting device. Background Art

[0002] A wire harness is a combination of multiple wires or cables used to transmit electricity, signals or data from one place to another. A wire harness usually includes an insulating sheath, wiring terminals, wires and insulating wrapping materials, etc. They are organized together to simplify the installation, maintenance and management process. Wire harnesses are widely used in many fields such as automobiles, home appliances, computers and communication equipment. In the process of wire harness production, the wire harness model needs to be cut according to actual needs.

[0003] During the use of the current wire cutting device for wire harness production, after the wire harness is cut, the cut end of the wire harness needs to be manually pulled over the blade by the staff before the cutting operation can continue, resulting in reduced efficiency. For this reason, we propose a wire cutting device for wire harness production. Utility Model Content

[0004] The utility model aims to provide a wire cutting device for wire harness production, which has the advantage of automatically completing the pulling of one end of the wire harness after cutting during the wire harness cutting process, without manual operation, thereby improving the efficiency. It solves the problem that in the current wire cutting device for wire harness production, when the wire harness cutting is completed, the one end of the wire harness after cutting needs to be manually pulled by the staff and passed over the blade before the cutting operation can continue, resulting in reduced efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire harness production cutting device, comprising a base, a conveying frame and a circular frame, wherein columns are symmetrically installed at positions on both sides of the upper surface of the base close to the front surface, the ends of the columns are connected to a top plate, a cylinder is installed on the upper surface of the top plate, a lifting plate is connected to the end of the cylinder output shaft, a knife seat is installed on the lower surface of the lifting plate, a blade is installed on the upper surface of the base, a right-angled trapezoidal plate is installed on the rear surface of the lifting plate, horizontal sliding rods are symmetrically installed at positions on both sides of the upper surface of the base, horizontal sliding sleeves are symmetrically installed at positions on both sides of the outer surface of the circular frame, push springs are connected to the rear surfaces of the two horizontal sliding sleeves, a through-opening is provided on the upper surface of the circular frame, and a right-angled trapezoidal block is installed inside the through-opening.

[0006] Preferably, vertical sliding sleeves are installed at both sides of the outer surface of the right-angled trapezoidal block, the upper surfaces of the two horizontal sliding sleeves are connected with vertical sliding rods and downward pressure springs, the two vertical sliding rods pass through the two vertical sliding sleeves respectively, and the ends of the two downward pressure springs are respectively connected to the lower surfaces of the two vertical sliding sleeves.

[0007] Preferably, the two horizontal sliding rods pass through two horizontal sliding sleeves respectively.

[0008] Preferably, both of the two columns pass through the lifting plate.

[0009] Preferably, a conveying rack is installed on the upper surface of the base near the front surface of the column, and conveying rollers are installed inside the two conveying racks near the upper surface and the lower surface. A conveying motor is installed on one side of the outer surface of the conveying rack, and the end of the conveying motor output shaft is connected to one end of the conveying roller near the conveying motor.

[0010] Preferably, the ends of the two conveying rollers facing away from the conveying motor are connected with synchronous gears, and the two synchronous gears are meshed with each other. A gear cover is installed on the side of the conveying frame facing away from the conveying motor, and the two synchronous gears are located inside the gear cover.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model achieves the automatic traction of one end of the wire harness after cutting by arranging a horizontal sliding rod, a horizontal sliding sleeve, a pushing spring, a return frame, a through-hole, a right-angled trapezoidal block, a right-angled trapezoidal plate, a top plate, a cylinder and a blade during the wire harness cutting process. The wire harness passes through the return frame and the conveying frame and is pressed by the right-angled trapezoidal block. In the process of the cylinder driving the lifting plate to descend, the inclined surface of the right-angled trapezoidal plate contacts the inclined surface of the right-angled trapezoidal block, forcing the return frame to move backward away from the blade and at the same time the pushing spring is compressed. As the knife seat descends and cooperates with the blade to complete the cutting of the wire harness, after the cutting is completed, the cylinder drives the lifting plate to rise, the compressed pushing spring is released, the return frame moves forward and approaches the blade, and the wire harness is also driven to move by the return frame, and one end of the cut wire harness passes over the top of the blade and enters the inside of the conveying frame, then the traction of one end of the wire harness after cutting is automatically completed, which is convenient for the subsequent cutting of the wire harness and improves the efficiency.

[0013] 2. The utility model achieves the effect of facilitating the movement of the wire harness driven by the circular frame by arranging a vertical slide rod, a vertical slide sleeve and a downward pressure spring. The elastic force of the downward pressure spring acts on the right-angled trapezoidal block, thereby increasing the downward pressure of the right-angled trapezoidal block on the wire harness inside the circular frame, so that the circular frame can drive the wire harness to move toward the blade.

[0014] 3. The utility model provides synchronous gears so that the two conveying rollers rotate synchronously towards each other, which is beneficial to the transmission of the wire harness. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 5 As shown, a wire harness production cutting device proposed by the utility model includes a base 6, a conveying frame 7 and a circular frame 22. The upper surface of the base 6 is symmetrically installed with columns 4 at positions on both sides near the front surface, the upper surface of the base 6 is installed with a conveying frame 7 near the front surface of the column 4, and the two conveying frames 7 are installed with conveying rollers 8 near the upper surface and the lower surface. A conveying motor 9 is installed on one side of the outer surface of the conveying frame 7. The end of the output shaft of the conveying motor 9 is connected to the end of the conveying roller 8 near the conveying motor 9. The ends of the two conveying rollers 8 facing away from the conveying motor 9 are connected with synchronous gears 18, and the two synchronous gears 18 are meshed. The conveying motor 9 drives one of the conveying rollers 8 to rotate, and the two conveying rollers 8 are transmitted through the two meshing synchronous gears 18, so that the two conveying rollers 8 rotate synchronously towards each other, and the wire harness passes between the two conveying rollers 8 and is conveyed by the two conveying rollers 8.

[0023] A gear cover 5 is installed on the side of the conveying frame 7 away from the conveying motor 9, and two synchronous gears 18 are located inside the gear cover 5. The end of the column 4 is connected to the top plate 2, and the upper surface of the top plate 2 is installed with a cylinder 1. The end of the output shaft of the cylinder 1 is connected to the lifting plate 3. The two columns 4 pass through the lifting plate 3. A knife seat 17 is installed on the lower surface of the lifting plate 3. A blade 21 is installed on the upper surface of the base 6. The blade 21 is located directly below the knife seat 17. In the process of the knife seat 17 being driven down by the cylinder 1, the cutting of the wire harness can be completed by cooperating with the blade 21. A right-angled trapezoidal plate 20 is installed on the rear surface of the lifting plate 3, horizontal slide bars 10 are symmetrically installed on both sides of the upper surface of the base 6, and horizontal sliding sleeves 11 are symmetrically installed on both sides of the outer surface of the circular frame 22. The two horizontal slide bars 10 pass through the two horizontal sliding sleeves 11 respectively, and the rear surfaces of the two horizontal sliding sleeves 11 are connected to push springs 12.

[0024] A through hole 19 is provided on the upper surface of the circular frame 22, and a right-angled trapezoidal block 13 is installed inside the through hole 19. The inclined surface of the right-angled trapezoidal block 13 contacts the inclined surface of the right-angled trapezoidal plate 20. Therefore, during the descending process of the right-angled trapezoidal plate 20, the right-angled trapezoidal block 13 and the circular frame 22 can be forced to move backward. Vertical sliding sleeves 15 are installed on both sides of the outer surface of the right-angled trapezoidal block 13. The upper surfaces of the two horizontal sliding sleeves 11 are connected with vertical sliding rods 14 and downward pressure springs 16. The two vertical sliding rods 14 pass through the two vertical sliding sleeves 15 respectively. The ends of the two downward pressure springs 16 are respectively connected to the lower surfaces of the two vertical sliding sleeves 15. The elastic force of the downward pressure spring 16 acts on the right-angled trapezoidal block 13, thereby increasing the downward pressure of the right-angled trapezoidal block 13 on the wiring harness inside the circular frame 22, so that the circular frame 22 can drive the wiring harness to move toward the blade 21.

[0025] When the utility model is in use, the wire harness passes through the circular frame 22 and the conveying frame 7 and is pressed by the right-angled trapezoidal block 13. During the process of the cylinder 1 driving the lifting plate 3 to descend, the inclined surface of the right-angled trapezoidal plate 20 contacts the inclined surface of the right-angled trapezoidal block 13, forcing the circular frame 22 to move backward away from the blade 21. At this time, the wire harness is fixed by the two conveying rollers 8 inside the conveying frame 7. During the movement of the circular frame 22, the wire harness does not move, and the push spring 12 is compressed. As the knife seat 17 descends and cooperates with the blade 21 to complete the cutting of the wire harness, after the cutting is completed, the cylinder 1 drives the lifting plate 3 to rise, and the compressed push spring 12 is released, so that the circular frame 22 moves forward and approaches the blade 21, and the wire harness is also driven to move by the circular frame 22. One end of the cut wire harness passes over the top of the blade 21 and enters the inside of the conveying frame 7, then the traction of the cut end of the wire harness is automatically completed, which is convenient for the subsequent cutting of the wire harness and improves the efficiency.

[0026] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
