Description

Technical Field

[0001] This utility model belongs to the field of wire harness processing technology, and in particular relates to a wire harness equal length cutting device. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-formed contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wire harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments. During production, wiring harnesses often need to be cut to size and then packaged according to production requirements.

[0003] Chinese utility model patent CN215544540U discloses a fixed-length cutting device for automotive wiring harnesses, relating to the technical field of fixed-length cutting equipment for wiring harnesses. The device includes an operating table with a limiting component fixed to its upper surface. A pair of longitudinally fixed plates are positioned on the right side of the limiting component and fixed to the upper surface of the operating table. A pair of sliding rods are fixed between the two fixed plates, and a U-shaped plate is fixed to the upper surface of the operating table between the two sliding rods. An electric telescopic rod is positioned on the upper surface of the U-shaped plate, with its extension rod penetrating the upper surface of the U-shaped plate and fixed with a longitudinally arranged cutting blade. A pad fixed to the upper surface of the operating table is positioned below the cutting blade. A connecting rod is fixed to the rear end of the cutting blade, and its rear end penetrates the inner rear surface of the U-shaped plate and is fixed with a vertically arranged rack. This utility model facilitates batch fixed-length cutting of wiring harnesses, reducing labor costs and improving production efficiency.

[0004] However, the aforementioned utility model patents still have some shortcomings:

[0005] The aforementioned utility model patent requires inserting the end of the wire harness between the right-angle plate and the receiving plate during use, and then using the spring force to squeeze and fix the wire harness. Furthermore, after each cut of the wire harness, the end of the wire harness needs to be pulled to re-fix it for the next cut, which is too cumbersome. Utility Model Content

[0006] This invention provides a wire harness equal-length cutting device, which aims to solve the problems mentioned in the background art.

[0007] This utility model is implemented as follows: a wire harness equal-length cutting device includes a processing table. Several wire harness grooves are arranged side by side on the top of the processing table. A lifting component, a cutting component, and a positioning component are sequentially installed on the processing table along the length direction of the wire harness grooves. A pushing component is installed on the lifting component. The pushing component includes a rotating rod connected to the lifting component. Several pushing wheels are installed on the side wall of the rotating rod. The pushing wheels correspond to the wire harness grooves and are positioned directly above the wire harness grooves.

[0008] Preferably, the lifting assembly includes U-shaped blocks, which are fixedly connected to the front and rear side walls of the processing table. Each U-shaped block is fitted with a slider, and a rotating seat is fixedly connected to the bottom of the slider from left to right. A threaded rod is rotatably installed inside the rotating seat, and each threaded rod is screwed into a threaded cylinder, which is fixedly connected to the left and right side walls of the U-shaped block.

[0009] Preferably, one end of the rotating rod is rotatably mounted on the side wall of the U-shaped block, and the other end of the rotating rod passes through another U-shaped block and is connected to the output shaft end of the motor. The motor is mounted on the side wall of the U-shaped block.

[0010] Preferably, the cutting component includes a mounting frame fixed to the top of the processing table. An electric lifting rod is mounted on the top of the mounting frame. The telescopic end of the electric lifting rod passes through the top of the mounting frame and is connected to a cutting blade. A cutting groove is provided directly below the cutting blade and on the top of the processing table. A scale is provided on the top of the processing table from the position of the cutting groove to the position of the positioning component.

[0011] Preferably, the positioning component includes a mounting plate fixedly connected to the bottom of the processing table. A screw is rotatably mounted between the mounting plates. A movable plate is screwed onto the side wall of the screw. L-shaped blocks are fixedly connected to the front and rear side walls of the movable plate. A signal transmitter and a signal receiver are respectively mounted on the top of the two L-shaped blocks. The signal transmitter and the signal receiver are arranged opposite to each other. The transmission height of the signal transmitter is located above the processing table.

[0012] Preferably, a controller is installed on the top of the processing table, and the controller is connected to the motor and the electric lifting rod respectively via wiring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The motor can control the rotating rod to drive several push wheels to rotate counterclockwise. The friction between the push wheels and the surface of the wire harness is used to push the wire harness to move automatically to the position of the cutting blade. There is no need to pull and press the wire harness after each cut, which is more convenient.

[0015] 2. The operator can turn the handle to rotate the threaded rod to adjust the height of the U-shaped block and the push wheel, so that the push wheel presses down and contacts the wire harness, which allows the push wheel to push wire harnesses of different diameters.

[0016] 3. When the wire harness moves to the position of the signal transmitter, the signal emitted by the signal transmitter is blocked by the wire harness. The controller responds and drives the motor to stop working. The wire harness stops moving. The electric lifting rod works to drive the cutting blade to move downward and then return to the initial position, thus completing one cutting operation of the wire harness. The length of the wire harness is the distance from the cutting groove to the signal transmitter. The cutting length of the wire harness can be adjusted by adjusting the position of the signal transmitter and the signal receiver. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 The present invention provides a technical solution: a wire harness equal length cutting device, including a processing table 1, a number of wire harness grooves 2 are arranged side by side on the top of the processing table 1, and a lifting component 3, a cutting component 5 and a positioning component 6 are installed on the processing table 1 along the length direction of the wire harness grooves 2, and a pushing component 4 is installed on the lifting component 3.

[0029] The pushing component 4 includes a rotating rod 41, which is connected to the lifting component 3. Several pushing wheels 43 are installed on the side wall of the rotating rod 41. The pushing wheels 43 correspond to the wire harness groove 2 and are located directly above the wire harness groove 2.

[0030] Specifically, the length direction of the wire harness groove 2 is consistent with the length direction of the processing table 1. The wire harness to be cut is placed in the wire harness groove 2 and can be automatically pushed towards the cutting component 5 by the pushing component 4.

[0031] A fixing plate 9 is fixedly attached to the left wall of the processing table 1. A roller 10 is rotatably mounted between the two fixing plates 9 via a rotating shaft, allowing excessively long wire harnesses to be suspended outside the processing table 1 for movement under the action of the pushing component 4. The roller 10 is designed to prevent the wire harnesses suspended outside the processing table 1 from rubbing against the edge of the processing table 1 and causing damage.

[0032] Furthermore, one end of the rotating rod 41 is rotatably mounted on the side wall of the U-shaped block 31, and the other end of the rotating rod 41 passes through another U-shaped block 31 and is connected to the output shaft end of the motor 42. The motor 42 is mounted on the side wall of the U-shaped block 31.

[0033] Specifically, motor 42 can control the rotating rod 41 to drive several push wheels 43 to rotate counterclockwise. The friction between the push wheels 43 and the surface of the wire harness is used to push the wire harness to move automatically to the position of the cutting component 5. At the same time, the lifting component 3 can drive the push wheels 43 to move vertically so as to press down and contact the wire harnesses of different apertures so as to perform frictional pushing.

[0034] Furthermore, the lifting assembly 3 includes a U-shaped block 31, which is fixedly connected to the front and rear side walls of the processing table 1. Each U-shaped block 31 is fitted with a slider 32, and the bottom of the slider 32 is fixedly connected to a rotating seat 33 on the left and right sides. A threaded rod 34 is rotatably installed inside the rotating seat 33. Each threaded rod 34 is screwed into a threaded cylinder 36, which is fixedly connected to the left and right side walls of the U-shaped block 31.

[0035] Specifically, a U-shaped block 31 is fixed to both the front and rear side walls of the processing table 1, and two sliding holes 37 are opened through the slider 32 so that the slider 32 can be fitted onto the two vertical side walls of the U-shaped block 31.

[0036] One end of the threaded rod 34 is rotatably mounted in the rotating seat 33, while the other end is fixedly connected to the handle 35, and its side wall is screwed into the threaded cylinder 36.

[0037] When it is necessary to adjust the height of the push wheel 43, two operators stand at the two U-shaped blocks 31 respectively, holding a handle 35 in each hand and rotating them simultaneously to adjust the height of the U-shaped blocks 31 in the vertical direction.

[0038] It should be noted that the threads on the sidewalls of the two threaded rods 34 on the same side are opposite, so that the operator can rotate the two threaded rods 34 in opposite directions to adjust the height.

[0039] Furthermore, the cutting component 5 includes a mounting frame 51, which is fixed to the top of the processing table 1. An electric lifting rod 52 is installed on the top of the mounting frame 51. The telescopic end of the electric lifting rod 52 passes through the top of the mounting frame 51 and is connected to a cutting blade 53. A cutting groove 54 is provided directly below the cutting blade 53 and on the top of the processing table 1. A scale 8 is provided on the top of the processing table 1 from the position of the cutting groove 54 to the position of the positioning component 6.

[0040] Specifically, the telescopic end of the electric lifting rod 52 controls the cutting blade 53 to move vertically to cut the wire harness at the cutting groove 54.

[0041] The setting of scale 8 allows operators to adjust the position of positioning component 6 according to production needs, so as to produce wire harnesses of different lengths. The length of the wire harness is the distance from cutting groove 54 to positioning component 6 (signal transmitter 66).

[0042] Furthermore, the positioning component 6 includes a mounting plate 61, which is fixedly attached to the bottom of the processing table 1. A screw 62 is rotatably mounted between the mounting plates 61. A movable plate 64 is screwed onto the side wall of the screw 62. L-shaped blocks 65 are fixedly attached to the front and rear side walls of the movable plate 64. A signal transmitter 66 and a signal receiver 67 are respectively mounted on the top of the two L-shaped blocks 65. The signal transmitter 66 and the signal receiver 67 are arranged opposite to each other. The transmission height of the signal transmitter 66 is located above the processing table 1.

[0043] Specifically, one end of the screw 62 is rotatably mounted on one of the movable plates 64, and the other end passes through another movable plate 64 and is connected to the output shaft end of the second motor 63, which is mounted on the movable plate 64.

[0044] The signal emitted by the signal transmitter 66 is received by the signal receiver 67. When the signal emitted by the signal transmitter 66 is blocked by the wire harness, the motor 42 stops working, the electric lifting rod 52 starts to cut the wire harness, and after the operator takes away the cut wire harness, the signal emitted by the signal transmitter 66 is received again by the signal receiver 67, and the motor 42 starts working to continue to push the wire harness to move.

[0045] Motor 63 is connected to controller 7. The operator can drive motor 63 through controller 7 to control screw 62 to rotate, so that moving plate 64 drives L-shaped block 65, signal transmitter 66 and signal receiver 67 to move in the horizontal direction to adjust the fixed length requirement of wire harness.

[0046] Furthermore, a controller 7 is installed on the top of the processing table 1. The controller 7 is connected to the motor 42 and the electric lifting rod 52 via wiring.

[0047] Specifically, the controller 7 is also connected to the signal receiver 67 via a line. When the signal receiver 67 does not receive the signal from the signal transmitter 66, the controller 7 responds by stopping the drive motor 42, and the electric lifting rod 52 drives the cutting blade 53 to move downward and then return to the initial position, thus completing one cutting operation.

[0048] It should be noted that the duration of signal reception by the signal receiver 67 can also be controlled by the controller 2 7. When the signal receiver 67 receives a signal exceeding the set value, it means that the wire harness has been cut and the remaining length is not enough to push to the signal transmitter 66. This can remind the staff to replenish the wire harness in time.

[0049] The working principle and usage process of this utility model: After the utility model is installed, the operator places the wire harness to be cut into the wire harness groove 2 and passes it under the push wheel 43. The operator turns the handle 35 to drive the threaded rod 34 to rotate, and adjusts the height of the U-shaped block 31 and the push wheel 43 so that the push wheel 43 presses down and contacts the wire harness.

[0050] The controller 7 drives the motor 42 to control the rotating rod 41 to simultaneously drive several push wheels 43 to rotate counterclockwise. The friction between the push wheels 43 and the surface of the wire harness is used to push the wire harness to move automatically towards the position of the cutting blade 53.

[0051] When the wire harness moves to the position of the signal transmitter 66, the signal emitted by the signal transmitter 66 is blocked by the wire harness. The controller 7 responds and drives the motor 42 to stop working. The wire harness stops moving. The electric lifting rod 52 works to drive the cutting blade 53 to move downward and then return to the initial position, thus completing one cutting operation of the wire harness. The length of the wire harness is the distance from the cutting groove 54 to the signal transmitter 66. The cut wire harness is extracted and stacked by the operator.

[0052] When the cutting length of the wire harness needs to be adjusted according to production requirements, the operator can drive the motor 63 through the controller 7 to control the screw 62 to rotate, so that the moving plate 64 drives the L-shaped block 65, the signal transmitter 66 and the signal receiver 67 to move in the horizontal direction, and adjust the fixed length requirement of the wire harness according to the scale 8.

[0053] It should be noted that the external power supply of controller 7 provides power to the drive unit of this device.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
