Description

Technical Field

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

[0002] The wire harness cutting device is a device specially used for cutting wire harnesses. It combines mechanical, electrical and automation technologies to efficiently and accurately complete the cutting of wire harnesses. The wire harness cutting device is mainly composed of a feeding device, a conveying mechanism, a positioning and clamping mechanism, a cutting mechanism and a control system. The wire harness cutting device is widely used in the wire harness production field of the automotive, electronics, communications and other industries. In these industries, the wire harness is an important part of electrical connection, and its cutting quality and efficiency directly affect the quality and production efficiency of the product.

[0003] For example, the Chinese patent "A wire harness processing and cutting device" with announcement number CN219997954U includes a wire harness cutting device, a wire harness collecting box is arranged on the left side of the wire harness cutting device, a slide groove is opened inside the wire harness collecting box, a connecting plate is slidably connected in the slide groove, the connecting plate is slidably connected in the wire harness collecting box, a through groove is opened on the left side of the wire harness collecting box, a collecting mechanism is arranged in the through groove, the collecting mechanism includes a round rod, the round rod is fixedly connected inside the through groove, a moving rod is provided on the sliding sleeve on the surface of the round rod, the moving rod is located on one side of the wire harness collecting box and is fixedly connected to the connecting plate, a first spring is provided on the movable sleeve on the surface of the round rod, and the two ends of the first spring are respectively fixedly connected between the through groove and the connecting plate, and a mounting plate is fixedly connected on the side of the wire harness collecting box close to the wire harness cutting device.

[0004] Although the above-mentioned prior art can realize the cutting of wire harnesses, in actual use, on the one hand, it is difficult to automatically perform the next cutting after the wire harness cutting is completed. After completing one wire harness cutting, the operator needs to re-fix the wire head before performing the next wire harness cutting, resulting in the need to shut down the machine for operation during the wiring process, thereby reducing the efficiency of wire harness cutting. On the other hand, it is difficult to keep the wire harness taut during wire harness cutting. During wire harness cutting, the blade squeezes the wire harness to a certain extent, causing the wire harness to loosen, resulting in the wire harness cutting position being offset, thereby reducing the quality of wire harness cutting. Therefore, it does not meet the existing needs. In this regard, we propose a wire harness cutting device. Utility Model Content

[0005] The utility model aims to provide a wire harness cutting device to solve the problems in the above background technology that it is difficult to automatically cut the wire harness for the next time after the wire harness is cut, and it is difficult to keep the wire harness taut during cutting.

[0006] To achieve the above object, the utility model provides the following technical solution: a wire harness cutting device, comprising a frame, wherein two frames are provided, a workbench is fixedly provided on the upper end of the frame, and mounting frames are fixedly provided on both sides of the upper end of the workbench; and further comprising:

[0007] A second fixing frame is arranged at the upper end of the workbench located on the inner side of the mounting frame on one side, a mounting plate is fixedly arranged between the mounting frames on one side, a second hydraulic telescopic device is fixedly arranged at the front and rear ends of one side of the mounting plate, and the telescopic end of the second hydraulic telescopic device extends to the other side of the mounting plate and is fixedly connected to the second fixing frame, and a limit rod is fixedly arranged between the mounting frames at the front and rear ends;

[0008] A slide groove is arranged inside the limiting rod, and connecting rods are fixedly arranged at the front and rear ends of the outside of the second fixed frame, and the connecting rods extend into the slide groove. A pulley is arranged outside the connecting rod located inside the slide groove, and the pulley is rotatably connected to the connecting rod, and the pulley and the slide groove are slidably limited.

[0009] Preferably, the workbench is fixedly provided with a first fixed frame at the upper end on one side of the second fixed frame, and the rear ends of the first fixed frame and the second fixed frame are both provided with driving cavities, a first rotating rod is rotatably provided above the middle position inside the first fixed frame and the second fixed frame, and the first rotating rod extends to the inside of the driving cavity, and a second rotating rod is rotatably provided below the middle position inside the first fixed frame and the second fixed frame, and the second rotating rod extends to the inside of the driving cavity.

[0014] Preferably, a cutting wheel is arranged inside the mounting ear plate, a first motor is fixedly arranged on one side outside the mounting ear plate, and an output shaft of the first motor extends into the interior of the mounting ear plate and is fixedly connected to the cutting wheel.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can make the second fixed frame move by the second hydraulic telescopic device and the pulley. After the wire harness is cut, the second hydraulic telescopic device is turned on to extend the telescopic end of the second hydraulic telescopic device. At this time, the telescopic end of the second hydraulic telescopic device is extended to push the second fixed frame to move on the workbench. At the same time, the pulleys on the connecting rods at both ends of the second fixed frame slide and cooperate with the slide grooves. When the second fixed frame moves to a suitable position, the second motor on the second fixed frame is turned on to make the output shaft of the second motor drive the driving roller to rotate counterclockwise. The friction force between the driving roller and the wire harness makes the cut wire harness pass through the second fixed frame again. At this time, the telescopic end of the second hydraulic telescopic device is contracted. The telescopic end of the second hydraulic telescopic device is contracted to restore the second fixed frame to its original position and carry out the next wire harness cutting, thereby avoiding the need for the operator to re-fix the wire harness after completing one wire harness cutting, thereby improving the efficiency of wire harness cutting.

[0017] 2. The utility model can keep the wire harness taut during cutting through the driving roller and the transmission roller. When the wire harness is cut, the wire harness passes through the driving rollers and the transmission rollers on both sides. At this time, the second motors on the first fixed frame and the second fixed frame are turned on at the same time, so that the second motor on the first fixed frame is energized in the forward direction and the second motor on the second fixed frame is energized in the reverse direction, so that the output shaft of the second motor on the first fixed frame drives the driving roller to rotate clockwise. At the same time, the driving roller on the first fixed frame is rotated counterclockwise through the cooperation of the driving gear and the transmission gear, and the output shaft of the second motor on the second fixed frame drives the driving roller to rotate counterclockwise. At the same time, the driving roller on the second fixed frame is rotated clockwise through the cooperation of the driving gear and the transmission gear. At this time, the friction force between the two ends of the wire harness and the transmission roller and the driving roller forms a pulling force, which pulls the wire harness to the two ends and keeps the wire harness taut for cutting, so as to avoid the loosening of the wire harness during cutting, thereby improving the accuracy of wire harness cutting.

[0018] 3. The utility model can change the height of the cutting wheel by providing a first hydraulic telescopic device. When cutting the wire harness, the wire harness is already in a taut and fixed state. The first hydraulic telescopic device is turned on, so that the telescopic end of the first hydraulic telescopic device drives the mounting ear plate to move downward, and the cutting wheel fixed inside the mounting ear plate also moves downward until the cutting wheel moves to a suitable position. Then, the first motor is turned on, so that the output shaft of the first motor drives the cutting wheel to rotate. The rotating cutting wheel completes the cutting of the wire harness, so that the cutting wheel can be adjusted in position according to the thickness of different wire harnesses, thereby adapting to wire harnesses of different thicknesses.
