Description

Technical Field

[0001] This utility model relates to the technical field of cutting devices for wire harnesses, specifically a cutting device for wire harnesses. Background Technology

[0002] With social development and technological advancements, in the production of wire harnesses, to facilitate installation and maintenance and ensure that electrical equipment can operate under the harshest conditions, wires of different specifications and colors used in various electrical devices throughout the vehicle are rationally arranged and bundled together with insulating materials. This results in a complete and neat assembly. However, during the assembly of existing wire harnesses, sometimes the harnesses are quite long and need to be cut. But during the cutting process, instability can easily occur, causing the wire harness to shift and resulting in an uneven cut surface. This fails to meet market demands for wire harness cutting, thus reducing its practicality. Furthermore, adjusting the length of the wire harness often requires manual adjustment by operators, leading to a large workload and low work efficiency.

[0003] A search revealed an existing technology (application number: CN202111003412.7) for an automatic wire harness cutting device. The document describes it as "including a cutting machine housing, an L-shaped support plate, and a transmission support frame. A slide rail is provided at the top of the cutting machine housing, and the L-shaped support plate is also provided at the top of the L-shaped support plate. A hydraulic lifting rod is provided at the top of the L-shaped support plate, and a cutting fixing rod is provided at the output end of the hydraulic lifting rod. Mounting and positioning blocks are provided on both sides of the cutting fixing rod, and the transmission support frame is located at the end of the cutting machine housing away from the L-shaped support plate." This utility model uses clamping and limiting blocks to buffer and fix the wire harness, making cutting more stable.

[0004] However, while the existing technology has improved the clamping and limiting blocks to buffer and fix the wire harness, making it more stable during cutting, it still has some shortcomings: it cannot cut multiple wire harnesses at once. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting device for wire harnesses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wire harness cutting device, comprising a device base including a junction box arranged above the device base, and a guide block fixedly arranged on the device base, the guide block having two sets of holes inside, through which a wire harness slides and passes for guiding the wire harness; a cutting mechanism including a cutting support fixedly arranged above the device base, two sets of guide columns fixedly arranged above the cutting support, and a fixing block above the two sets of guide columns, the fixing block having a cylinder fixedly arranged for driving a lifting cutting component on the guide columns to cut the wire harness; and a transmission mechanism including a support block arranged between the cutting support and the guide block, and a motor arranged on one side of the support block, the motor output end having a guide component for transmitting the wire harness.

[0007] As a further description of the above technical solution:

[0008] The lifting and cutting assembly includes: a feed block that slides through two sets of guide columns; a first blade that is fixedly arranged below the feed block; and a second blade that is fixedly arranged on the cutting support and positioned between the two sets of guide columns.

[0009] As a further description of the above technical solution:

[0010] The output end of the cylinder is fixedly connected above the feed block. When the cylinder is started, the output end of the cylinder drives the feed block to press down, causing the blade to cut the wire harness downwards, and then the wire harness falls into the junction box.

[0011] As a further description of the above technical solution:

[0012] The conveying assembly includes: a conveying roller, which is rotatably arranged on two sets of support frames on the base of the device, and one end of the conveying roller is fixedly connected to a motor; and a connecting column, which is rotatably arranged above the conveying roller, and a rolling wheel is fixedly provided on the connecting column.

[0013] As a further description of the above technical solution:

[0014] The rolling wheel abuts against the surface of the conveying roller. When the motor is started, it drives the conveying roller to rotate. The wire harness drives the rolling wheel to rotate through the friction of the rotating conveying roller, thus moving the wire harness forward.

[0015] As a further description of the above technical solution:

[0016] The guiding component includes: a support frame, fixedly arranged on one side of the junction box; and two sets of guide grooves, fixedly arranged on the support frame, through which the wire harness passes for guiding the wire harness.

[0017] As a further description of the above technical solution:

[0018] The guide groove is hollow and cylindrical, used for internal wire harness passage.

[0019] This utility model has the following beneficial effects:

[0020] 1. The guide block on the base of the device pre-guides the wire harness, keeping it in a relatively stable position before entering the transmission and cutting stage. The two sets of hollow columnar guide grooves in the guide assembly further guide the wire harness precisely, preventing it from shifting, bending or tangling during transmission and cutting, and allowing multiple wire harnesses to be cut simultaneously.

[0021] 2. The feed block is driven by a cylinder to slide precisely on the guide post, ensuring that the first blade is pressed down vertically and cooperates with the fixed second blade to accurately cut the wire harness, ensuring the flatness and consistency of the wire harness cut, and meeting the requirements of different application scenarios for wire harness cut length and quality.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figures 1 to 4As shown, this embodiment provides a wire harness cutting device, comprising: a device base 11, including a junction box 12 arranged above the device base 11, and a guide block 33 fixedly arranged on the device base 11, the guide block 33 having two sets of holes inside, and a wire harness 4 sliding through the holes for guiding the wire harness 4; a cutting mechanism, including a cutting support 25 fixedly arranged above the device base 11, two sets of guide columns 21 fixedly arranged above the cutting support 25, and a fixing block above the two sets of guide columns 21, and a cylinder 2 fixedly arranged on the fixing block for driving the lifting cutting component on the guide column 21 to cut the wire harness 4; and a transmission mechanism, including a support block arranged between the cutting support 25 and the guide block 33, and a motor 31 arranged on one side of the support block, and a guide component arranged at the output end of the motor 31 for transmitting the wire harness 4.

[0030] In this embodiment, the device base 11, the cutting mechanism, and the transmission mechanism constitute the wire harness cutting device involved in this application, realizing a wire harness cutting device. The wire harness in this application generally refers to the wire harness used in the semiconductor industry. This device can be used as long as wire harness cutting is required. This application does not limit the specific type of wire harness.

[0031] In this embodiment, the hole in the guide block 33 provides a guiding path for the wire harness 4, enabling it to accurately reach the cutting position, and the cut wire harness falls into the junction box 12.

[0032] In this embodiment, the cylinder 2 generates power to drive the lifting and cutting assembly to move along the guide post 21 to cut the wire harness.

[0033] It should be noted that the guide block 33 can be made of metal and is fixed on the device base 11. It has two sets of circular holes inside for the wire harness 4 to pass through and be guided.

[0034] Specifically, the lifting and cutting assembly includes: a feed block 24 that slides through two sets of guide posts 21; a first blade 22 that is fixedly arranged below the feed block 24; and a second blade 23 that is fixedly arranged on the cutting support 25 and positioned between the two sets of guide posts 21.

[0035] In this embodiment, the output end of cylinder 2 drives the feed block 24 to press down, causing the first blade 22 to move downward, working together with the second blade 23 to cut the wire harness, precisely controlling the cutting action and efficiently cutting the wire harness.

[0036] Specifically, the output end of the cylinder 2 is fixedly connected above the feed block 24. When the cylinder 2 is started, the output end of the cylinder 2 drives the feed block 24 to press down, causing the blade 22 to cut the wire harness 4 downwards, thereby causing the wire harness 4 to fall into the junction box 12.

[0037] In a preferred embodiment, the motor 31 drives the conveyor roller 3 to rotate, and the conveyor roller 3 drives the wire harness 4 forward through friction with the wire harness 4. At the same time, the wire harness drives the roller 36 to rotate, so that the wire harness is continuously and automatically conveyed.

[0038] Specifically, the conveying assembly includes: a conveying roller 3, which is rotatably arranged on two sets of support frames 35 on the device base 11, and one end of the conveying roller 3 is fixedly connected to a motor 31; and a connecting column 32, which is rotatably arranged above the conveying roller 3, and a rolling wheel 36 is fixedly provided on the connecting column 32.

[0039] It should be noted that when the motor 31 is started, it drives the conveyor roller 3 to rotate. The conveyor roller 3 contacts the surface of the wire harness 4 and drives the wire harness 4 to move through friction. The wire harness 4 then drives the roller 36 to rotate, which can stably transmit the wire harness.

[0040] Specifically, the rolling wheel 36 abuts against the surface of the conveying roller 3 and the wire harness 4. When the motor 31 is started, it drives the conveying roller 3 to rotate. The wire harness 4 drives the rolling wheel 36 to rotate through the friction of the rotating conveying roller 3, so that the wire harness 4 moves forward.

[0041] In a preferred embodiment, the roller 36 and the conveyor roller 3 abut against the wire harness 4. When the motor 31 is started, the roller 36 and the conveyor roller 3 clamp the wire harness 4 and rotate, causing the wire harness 4 to move forward continuously.

[0042] Example 2:

[0043] Based on Example 1, in order to further improve the continuous pushing of the wire harness 4 forward, a motor 31 is fixedly connected to one side of the conveyor roller 3. The motor 31 is started to make the conveyor roller 3 rotate and drive the wire harness 4 forward.

[0044] Specifically, the guiding components include: a support frame 35, which is fixedly arranged on one side of the junction box 12; and two sets of guide grooves 34, which are fixedly arranged on the support frame 35, with the wire harness 4 passing through the guide grooves 34 for guiding the wire harness 4.

[0045] It should be noted that the guide groove 34 constrains the wire harness 4, ensuring that it maintains a straight line during transmission and accurately reaches the cut-off position.

[0046] Specifically, the guide groove 34 is a hollow column shape, used for internal passage of the wire harness 4.

[0047] In this embodiment, the hollow cylindrical guide groove 34 encloses the wire harness 4, restricting its lateral movement, ensuring that the wire harness is transmitted in a set direction, guiding the wire harness, and ensuring the accuracy of wire harness transmission and cutting.

[0048] In use, the operator passes the wire harness 4 through the guide block 33, starts the motor 31, drives the conveyor roller 3 to rotate, the wire harness 4 extends between the two conveyor rollers 3 for transmission, passes through the guide groove 34, and then enters the cutting device. The cylinder 2 is started, pushing the feed block 24 downward. The first blade 22 connects to the feed block 24 and feeds the wire harness 4 downward, making contact with the second blade 23 to cut it. The cut wire harness 4 falls onto the junction box 12 for collection.

[0049] Finally, it should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
