Description

Technical Field

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

[0002] A wire harness is a complete unit composed of multiple cables or wires connected by connectors, clamps, insulating sleeves, and other components. It is commonly used in equipment such as automobiles, aircraft, home appliances, and computers, serving as an electrical connection and signal transmission device. By connecting various electrical components and control systems, wire harnesses ensure the normal operation of equipment and avoid the confusion and poor contact problems that can occur when installing individual wires. During the production process, wire harnesses need to be cut to ensure that the length of each harness meets specifications and to guarantee product consistency and quality stability on the production line.

[0003] Authorized announcement number CN222695906U discloses a wire harness cutting device for automotive wire harness production, including a workbench. The workbench surface has multiple cutting grooves, and cutting blades are installed above the cutting grooves. Each cutting blade has a fixed block fixedly installed at its top. A connecting box is located above the fixed blocks, and multiple springs are installed at the top of the connecting box. A connecting plate is fixedly installed on the top surface of the connecting box. This invention mainly achieves simultaneous cutting of multiple wire harnesses by setting multiple cutting grooves on the workbench and correspondingly installing multiple cutting blades. Through the coordinated use of the connecting box, horizontal plate, springs, and other components, the cutting blades remain stable during the cutting process. Even if the cutting blades are subjected to a certain impact force, the springs can buffer the impact and reduce damage to the cutting blades, thereby improving the overall stability of the equipment.

[0004] In the above technical solution, the use of components such as connecting box, cross plate, and spring can make the cutting blade stable during the cutting process. Even if the cutting blade is subjected to a certain impact force, the spring can reduce the damage to the cutting blade through buffering, thereby improving the stability of the entire equipment. However, during the cutting process, the wire harness needs to be placed inside the cutting groove, and there is no fixing mechanism to fix the wire harness. This may cause the wire harness to shift during the cutting process, affecting the cutting effect. Utility Model Content

[0023] The slide 61 has two slides, and the inner walls of the two slides 61 are respectively connected to the first rotating rod 62 and the second rotating rod 67. The outer wall of the second rotating rod 67 is fixedly connected to the handle 69.

[0024] The throttle 69 rotates, which in turn drives the second rod 67 to rotate. The rotation of the second rod 67, in turn, drives the first rod 62 to rotate synchronously via the transmission belt 68.

[0025] The outer wall of the first rotating rod 62 is connected to a transmission belt 68, and the end of the transmission belt 68 away from the first rotating rod 62 is connected to the outer wall of the second rotating rod 67. Both the first rotating rod 62 and the second rotating rod 67 are fixedly connected to a bidirectional threaded rod 63 at the end near the slide groove 61.

[0026] The rotation of the first rotating rod 62 and the second rotating rod 67 both drive the bidirectional threaded rod 63 to rotate, which in turn drives the movable block 64 to move in opposite directions.

[0027] The bidirectional threaded rod 63 has two types of threads that are threaded through its outer surface and connected to a movable block 64. The top of the movable block 64 is rotatably connected to a rotating wheel 65, and the outer surface of the rotating wheel 65 has a groove 66.

[0028] The two rotating wheels 65 can clamp and fix wire harnesses of different sizes using the grooves 66 on their outer surfaces without affecting the forward and backward movement of the wire harnesses.

[0029] The electric push rod 3 has an installation mechanism 7 at its bottom end, a fixing plate 79 is fixedly connected to the bottom end of the electric push rod 3, an installation groove 71 is opened at the top end of the fixing plate 79, an insert block 72 is slidably connected to the inner wall of the installation groove 71, and a cutter 73 is fixedly connected to the top end of the insert block 72.

[0030] The installation mechanism 7 enables the quick installation and removal of the cutter 73, facilitating replacement and maintenance by staff.

[0031] The outer wall of the insert 72 is provided with a positioning hole 74, and the top of the fixing plate 79 is fixedly connected to a fixing post 75. The outer wall of the fixing post 75 is slidably connected to a positioning rod 76.

[0032] The positioning rod 76 has the same vertical cross-sectional dimensions as the positioning hole 74.

[0033] The positioning rod 76 is fixedly connected to the outer wall of a movable plate 77. A spring 78 is fixedly connected to the end of the movable plate 77 near the positioning rod 76. The end of the spring 78 away from the movable plate 77 is fixedly connected to the outer wall of the fixed column 75.

[0035] This utility model provides a wire harness cutting device for wire harness production, the specific working principle of which is as follows:

[0036] In use, place the wire harness to be cut above the receiving plate 4, with the wire harness positioned between the two rotating wheels 65. Turn the handle 69, which drives the second rotating rod 67 to rotate. The rotation of the second rotating rod 67 drives the first rotating rod 62 to rotate via the transmission belt 68. The first rotating rod 62 and the second rotating rod 67 rotate synchronously. The first rotating rod 62 and the second rotating rod 67 respectively drive the bidirectional threaded rod 63 to rotate. The rotation of the bidirectional threaded rod 63 drives two movable blocks 64 to move in opposite directions inside the slide groove 61. The movement of the movable blocks 64 drives the rotating wheels 65 to move, bringing the two rotating wheels 65 closer together to the wire harness. The wire harness is fixed inside the groove 66, thus maintaining the stability of the wire harness during the cutting process and ensuring product quality. After long-term use, when the cutter 73 wears out and needs to be replaced, the moving plate 77 is pulled outward. The moving plate 77 moves and drives the positioning rod 76 to move, while pulling the spring 78, so that the spring 78 is in a stretched state until the positioning rod 76 is disengaged from the positioning hole 74. At this time, the insert block 72 is disengaged from the limit and moves downward. The insert block 72 is disengaged from the mounting groove 71, which makes it easier for the staff to install and disassemble the cutter 73, greatly improving work efficiency.
