Description

Technical Field

[0001] The utility model relates to the technical field of automotive wire harness cutting machines, and specifically relates to a cutting machine for automotive wire harness production. Background Art

[0002] In the process of automotive wire harness production, a cutting machine is an indispensable and important piece of equipment, which is used to cut the wire harness into specific lengths to meet the assembly requirements in the automotive manufacturing process. With the rapid development of the automotive industry, the performance requirements for wire harness cutting machines are also getting higher and higher, especially in terms of cutting accuracy, efficiency, and stability.

[0003] In the cutting process of traditional automotive wire harness cutting machines, it is often difficult to maintain a constant tension of the wire harness, resulting in unstable cutting quality, uneven cut surfaces, and even possible situations such as wire harness breakage or excessive stretching. In addition, when adjusting the cutting parameters of traditional cutting machines, manual operation is usually required, which is cumbersome and difficult to ensure accuracy. Summary of the Utility Model

[0004] (I) Purpose of the Utility Model

[0005] In view of this, the purpose of the present utility model is to propose a cutting machine for automotive wire harness production, which solves the problems raised in the above background.

[0006] (II) Technical Solution

[0007] A cutting machine for automotive wire harness production includes a base, both ends of the base are fixedly installed with fixing plates, and a cylinder is fixedly installed at the top of the fixing plates. One end of the cylinder is connected with a cutting knife, one side of the bottom end of the cutting knife is connected with a fixing frame, and two sides of one end of the fixing frame are fixedly installed with limiting plates. A plurality of groups of first rotating rollers are movably installed between the limiting plates. The other end of the fixing frame is movably installed with a second rotating roller, and a supporting plate is fixedly installed in the middle of the fixing frame. A first motor is arranged on one side of the supporting plate, one end of the first motor is connected with a tension roller, and a tension sensor is arranged on one side of the first motor.

[0008] Preferably, installation grooves are opened on both inner walls of the fixing plates, and two groups of fixing seats are fixedly installed in the installation grooves. Circular through grooves are opened on the outer surfaces of the two groups of fixing seats, and lead screws are movably installed in the circular through grooves. Moving blocks are movably installed on the outer surfaces of the lead screws, and one end of the moving block is connected with a limiting frame. During operation, the operator can rotate the lead screw to make the moving block move along the lead screw, thereby driving the position of the limiting frame to change. In this way, the distance between the limiting frame and the cutting area can be conveniently adjusted to adapt to wire harnesses of different sizes.

[0009] Preferably, a limiting groove is formed at the bottom end of the limiting frame, and a plurality of limiting rollers are movably installed in the limiting groove. When the wire harness passes through the limiting frame, it will come into contact with the limiting rollers. Since the limiting rollers are rolling, they can reduce the friction of the wire harness during transmission, enabling the wire harness to pass through the limiting frame more smoothly. At the same time, the limiting rollers can also play a role in supporting and guiding, ensuring that the wire harness maintains the correct position and path during transmission.

[0010] Preferably, one end of the screw rod is connected with a locking member, and the other end of the screw rod is connected with a second motor. The second motor is fixedly connected to the fixed seat. By precisely controlling the rotation angle and speed of the screw rod through the second motor, precise adjustment of the position of the limiting frame can be achieved, improving the cutting accuracy and product quality. Moreover, the automatic adjustment method can greatly reduce the time and labor intensity of manual operation, improving production efficiency. At the same time, due to the more accurate and rapid adjustment process, errors and wastes caused by human factors are also reduced.

[0011] Preferably, a protective plate is fixedly installed on one side of the installation groove. The protective plate can effectively shield and protect key components such as the fixed seat and the screw rod inside the installation groove, preventing these components from being collided or damaged by external objects during operation, thereby extending the service life of the entire adjustment mechanism.

[0012] Preferably, reinforcing plates are fixedly installed on both sides of the support plate. The installation of the reinforcing plates can significantly enhance the structural strength of the support plate, enabling it to withstand greater tension and pressure, thereby preventing deformation or fracture during operation and improving the stability and reliability of the entire cutting machine.

[0013] Preferably, a support member is connected to the bottom end of the base, and one end of the support member is connected to a fixed frame. The design of the support member can effectively increase the contact area between the base and the ground, thereby enhancing the stability of the entire cutting machine. This helps to prevent the equipment from shaking or tilting during operation, ensuring the smooth progress of the cutting operation.

[0014] From the above technical solutions, it can be seen that the present application has the following beneficial effects:

[0015] 1. The utility model monitors the wire harness tension in real time through a tension sensor and precisely adjusts the rotation speed of the tension roller according to the real-time data to ensure that the wire harness maintains a constant tension state during cutting. This avoids problems such as uneven cuts, stretching, or breakage caused by uneven tension, thereby greatly improving the cutting quality and stability.

[0016] 2. This utility model makes the entire cutting process more efficient through automated tension control and precise cutting mechanisms. By precisely controlling the rotational speed of the first motor, the tension roller can quickly respond to tension changes and maintain a constant wire harness tension, thereby reducing downtime and resource waste caused by improper tension adjustment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following description is essentially exemplary only and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. In a specific part of a specific drawing, the relevant details or structures of the embodiments of the present disclosure may be illustrated in an exaggerated manner.

[0024] Please refer to Figures 1-5 , an embodiment provided by this utility model:

[0025] A cutting machine for automobile wire harness production, including a base 4, fixed plates 1 are fixedly installed at both ends of the base 4, and a cylinder 2 is fixedly installed at the top of the fixed plates 1. One end of the cylinder 2 is connected to a cutter 3. One side of the bottom end of the cutter 3 is connected to a fixed frame 8. Limit plates 6 are fixedly installed on both sides of one end of the fixed frame 8. A plurality of first rotating rollers 7 are movably installed between the limit plates 6. A second rotating roller 913 is movably installed at the other end of the fixed frame 8. A support plate 915 is fixedly installed in the middle of the fixed frame 8. A first motor 911 is arranged on one side of the support plate 915. One end of the first motor 911 is connected to a tension roller 9. A tension sensor 912 is arranged on one side of the first motor 911.

[0026] Furthermore, installation grooves are formed on both inner walls of the fixed plate 1, and two groups of fixed seats 811 are fixedly installed in the installation grooves. Circular through grooves are formed on the outer surfaces of the two groups of fixed seats 811, and a lead screw 812 is movably installed in the circular through grooves. A movable block 814 is movably installed on the outer surface of the lead screw 812. One end of the movable block 814 is connected to a limit frame 611. During operation, an operator can rotate the lead screw 812 to move the movable block 814 along the lead screw 812, thereby driving the position of the limit frame 611 to change. In this way, the distance between the limit frame 611 and the cutting area can be conveniently adjusted to adapt to wire harnesses of different sizes.

[0027] Furthermore, a limit groove is formed at the bottom end of the limit frame 611, and a plurality of limit rollers 612 are movably installed in the limit groove. When the wire harness passes through the limit frame 611, it will come into contact with the limit rollers 612. Since the limit rollers 612 are rolling, they can reduce the friction of the wire harness during transmission, enabling the wire harness to pass through the limit frame more smoothly. At the same time, the limit rollers 612 can also play a role in supporting and guiding to ensure that the wire harness maintains the correct position and path during transmission.

[0028] Furthermore, one end of the lead screw 812 is connected to a locking member 813, and the other end of the lead screw 812 is connected to a second motor 816. The second motor 816 is fixedly connected to the fixed seat 811. By precisely controlling the rotation angle and speed of the lead screw 812 through the second motor 816, precise adjustment of the position of the limit frame 611 can be achieved, improving the cutting accuracy and product quality. And the automatic adjustment method can greatly reduce the time and labor intensity of manual operation and improve production efficiency. At the same time, due to the more accurate and rapid adjustment process, errors and waste caused by human factors are also reduced.

[0029] Furthermore, a protective plate 5 is fixedly installed on one side of the installation groove. The protective plate 5 can effectively shield and protect key components such as the fixed seat 811 and the lead screw 812 inside the installation groove, preventing these components from being collided or damaged by external objects during operation, thereby extending the service life of the entire adjustment mechanism.

[0030] Furthermore, reinforcing plates 914 are fixedly installed on both sides of the support plate 915. The installation of the reinforcing plates 914 can significantly enhance the structural strength of the support plate 915, enabling it to withstand greater tension and pressure, thereby preventing deformation or fracture during operation, and improving the stability and reliability of the entire cutting machine.

[0031] Furthermore, a support member 111 is connected to the bottom end of the base 4, and one end of the support member 111 is connected to a fixing frame 8. The design of the support member 111 can effectively increase the contact area between the base 4 and the ground, thereby enhancing the stability of the entire cutting machine. This helps prevent the equipment from shaking or tilting during operation and ensures the smooth progress of the cutting operation.

[0032] Working principle: During operation, first place the automotive wire harness to be cut between the first rotating roller 7 and the second rotating roller 913, and through the rotation of the second rotating roller 913, the transmission of the wire harness is realized. During the transmission process, the wire harness is subjected to a certain tension, and this tension acts on the wire harness through the tension roller 9. The tension sensor 912 monitors the tension of the wire harness in real time and transmits the monitored tension data to the control system. The control system adjusts the rotation speed of the tension roller 9 by controlling the rotation speed of the first motor 911 according to the preset tension parameters and the received real-time tension data, thereby achieving precise control of the wire harness tension. When the tension is too large, the rotation speed of the first motor 911 is reduced, the rotation speed of the tension roller 9 is decreased, and the tension of the wire harness is reduced; when the tension is too small, the rotation speed of the first motor 911 is increased, the rotation speed of the tension roller 9 is increased, and the tension of the wire harness is increased. In this way, it can ensure that the wire harness maintains a constant tension state during cutting, improving the cutting quality and stability. When the wire harness is transmitted to the position of the cutting knife 3, the cylinder 2 drives the cutting knife 3 to press down to achieve the cutting of the wire harness. Since the wire harness maintains a constant tension during cutting, the cut is smooth and there is no stretching or breaking phenomenon. At the same time, by adjusting the stroke and speed of the cylinder 2, the cutting depth and cutting speed of the cutting knife 3 can be controlled to meet the cutting requirements of different wire harnesses.
