Description

Technical Field

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

[0002] A positioning device for wire harness cutting is a specialized positioning device used in the wire harness cutting process. Its main function is to accurately position the wire harness before cutting to ensure the accuracy and efficiency of the cutting. This device uses a series of mechanical or electronic mechanisms to clamp, straighten, and position the wire harness, thereby meeting the needs of the cutting process. Existing wire harness cutting equipment usually has a wire guide tube installed on the side of the cutting blade. The presence of the wire guide tube can ensure the accuracy of the wire position during cutting. By precisely controlling the position of the wire in the wire guide tube, the cutting accuracy and stability can be further improved, thereby meeting higher processing requirements.

[0003] However, when traditional wire harness cutting and processing equipment passes the wire harness body through the wire conduit, the limited internal space of the conduit and the compact installation of the components result in a small operating space and obstructed vision, making it difficult to flexibly use the wire pulling tools and wires, which brings great inconvenience to the wire pulling work.

[0024] Please see Figures 1-6 As shown, a positioning device for wire harness cutting and processing includes a housing 1. A positioning structure 6 is mounted on the housing 1 via a movable structure 7. The movable structure 7 includes a mounting plate 701. The mounting plate 701 is slidably connected to the housing 1. The mounting plate 701 has multiple limiting holes 704. A connecting block 702 is fixedly connected to the housing 1. A limiting rod 703 is slidably connected to the connecting block 702. The top end of the limiting rod 703 engages with the limiting hole 704. The positioning structure 6 includes a second hydraulic rod 604. The second hydraulic rod 604 is mounted on the mounting plate 701. The extended end is fixedly connected to a rotating ring 605, and a second rotating shaft 606 is fixedly connected inside the rotating ring 605. A connecting rod 607 is rotatably connected to the second rotating shaft 606. A fixed seat 601 is fixedly connected to the housing 1. A first rotating shaft 602 is rotatably connected to the fixed seat 601. A fixed frame 603 is rotatably connected to the first rotating shaft 602. The bottom end of the fixed frame 603 is fixedly connected to the connecting rod 607. A wire conduit 608 is installed on the fixed frame 603. A wire harness body 3 is slidably connected inside the wire conduit 608. A cutting assembly 2, a driving structure 4, and an installation structure 8 are installed on the housing 1.

[0025] As a technical optimization of this utility model, the mounting plate 701 has a "T" shaped cross-section, the first rotating shaft 602 has a "T" shaped cross-section, a fixing block 5 is installed on the housing 1, and the wire harness body 3 is slidably connected to the fixing block 5; the fixing block 5 has a positioning and guiding function for the wire harness body 3, preventing the cutting component 2 from cutting the wire harness body 3 unevenly due to the bending of the wire harness body 3 when it is stripped.

[0026] As a technical optimization of this utility model, a pressure ring 706 is fixedly connected to the limiting rod 703, and a first spring 705 is fixedly connected between the connecting block 702 and the pressure ring 706; the first spring 705 resets and drives the limiting rod 703 to engage with the limiting hole 704.

[0027] As a technical optimization of this utility model, four screws 609 are rotatably connected to the fixing frame 603. The ends of the screws 609 are arc-shaped and abut against the conduit 608. The screws 609 have a fixing function on the conduit 608, which facilitates the installation of the conduit 608.

[0028] As a technical optimization of this utility model, a mounting bracket 610 is mounted on the mounting structure 8. Four first positioning wheels 611 are rotatably connected to the mounting bracket 610. A sliding plate 612 is slidably connected to the mounting bracket 610. Three second positioning wheels 613 are rotatably connected to the sliding plate 612. The first positioning wheels 611 and the second positioning wheels 613 are all rollably connected to the wire harness body 3. A lead screw 614 is rotatably connected to the mounting bracket 610, and the lead screw 614 is threadedly connected to the sliding plate 612. The wire harness is then... The main body 3 is sequentially inserted into the grooves on the first positioning wheel 611 and the second positioning wheel 613, thereby guiding and positioning the wire harness main body 3 through the two first positioning wheels 611 and the second positioning wheels 613. When the diameter of the wire harness main body 3 to be processed changes, the lead screw 614 is rotated, and the lead screw 614 drives the slide plate 612 to slide on the mounting bracket 610. While the slide plate 612 is sliding, it drives multiple second positioning wheels 613 to press down on the wire harness main body 3, thereby making the positioning effect of the first positioning wheel 611 and the second positioning wheel 613 on the wire harness main body 3 better.

[0029] As a technical optimization of this utility model, the mounting structure 8 includes a slider 801. A slider 801 with a "T"-shaped cross-section is slidably connected to the housing 1. A slot 803 is provided on the slider 801. A locking block 802 is slidably connected to the housing 1, engaging with the slot 803. A guide rod 805 is fixedly connected to the housing 1, slidably connecting the locking block 802 and the guide rod 805. A second spring 804 is sleeved on the outside of the guide rod 805, with one end of the second spring 804 fixedly connected to the housing 1. The other end is fixedly connected to the locking block 802. When the number of wire harness bodies 3 to be processed increases and the first positioning wheel 611 and the second positioning wheel 613 need to be replaced, a hexagonal wrench is inserted into the groove of the locking block 802 and pressed down so that the locking block 802 is no longer engaged with the slot 803 on the slider 801. At this time, the locking block 802 retracts against the second spring 804 and then pulls the mounting bracket 610 outward. The mounting bracket 610 drives the slider 801 to slide out of the housing 1, which facilitates the replacement of the mounting bracket 610 with the first positioning wheel 611 and the second positioning wheel 613 of the specifications corresponding to the number of wire harness bodies 3 to be processed.

[0030] As a technical optimization of this utility model, the driving structure 4 includes a driving roller 401. Two sets of driving rollers 401 are rotatably connected to the housing 1. The two sets of driving rollers 401 are located on both sides of the cutting assembly 2. A pulley 403 is fixedly connected to the driving roller 401. The same belt 404 is wound around the two pulleys 403 in the same set. Two sets of driven rollers 402 are rotatably connected to the housing 1. Two motors 405 are installed on the housing 1. The output end of the motor 405 is fixedly connected to the driving roller 401. A first hydraulic rod 406 is installed on the housing 1. A connecting frame 407 is fixedly connected to the extended end of the first hydraulic rod 406. The connecting frame 407 is rotatably connected to the driven roller 402. When it is necessary to adjust the distance between the driving roller 401 and the driven roller 402, the first hydraulic rod 406 is activated. The first hydraulic rod 406 drives the two sets of driven rollers 402 downwards via the connecting frame 407, causing the driven rollers 402 to contact the wire harness body 3 downwards. Then, two motors 405 are activated, and the two motors 405 drive the two... The drive roller 401 rotates, simultaneously moving the wire harness body 3. This creates friction between the wire harness body 3 and the driven roller 402, causing the driven roller 402 to rotate. Through the cooperation of the drive roller 401 and the driven roller 402, the wire harness body 3 moves. When the wire harness body 3 passes through the cutting assembly 2 and its end is positioned on the set of drive rollers 401 and driven rollers 402 responsible for unloading, the wire harness body 3 is cut by the cutting blade. At this point, the second hydraulic rod 604 is activated, extending and driving the connecting rod via the second rotating shaft 606. 607 rotates toward the cutting assembly 2, and the connecting rod 607 drives the fixing frame 603 to rotate on the first rotating shaft 602. At the same time, the fixing frame 603 drives the wire tube 608 to rise toward one end of the cutting assembly 2. The wire tube 608 has a guiding and positioning function for the wire harness body 3, and also provides good protection for the wire harness body 3. At this time, the drive roller 401 and the driven roller 402 responsible for feeding rotate in opposite directions, driving the cut wire harness body 3 to move toward the cutting assembly 2. The cutting assembly 2 performs wire stripping work on the end of the wire harness body 3.

[0031] In use, the following steps are performed: First, the wire is threaded. Pulling down the limiting rod 703 releases it from the limiting hole 704, causing the pressure ring 706 to slide downwards. Simultaneously, the pressure ring 706 slides and contracts against the first spring 705. Then, pulling outwards the fixing bracket 603 causes it to slide on the first rotating shaft 602. At the same time, the fixing bracket 603, via the connecting rod 607, causes the wire conduit 608, the second hydraulic rod 604, and the mounting plate 701 to slide away from the housing 1. Once the mounting plate 701 has slid to the appropriate position, it is released. The limiting rod 703 engages with another limiting hole 704, thereby limiting the mounting plate 701 and ensuring that both ends of the wire conduit 608 are unobstructed, increasing the operating space and making the wire threading process more convenient and flexible. Then, the wire harness body 3 is pulled out to a certain length and passed through the wire conduit 608, with the end of the wire harness body 3 positioned on the cutting assembly 2. The end of the wire harness body 3 facing the mounting plate 701 is then placed between the two driving rollers 401 and the two driven rollers 402. Finally, the wire harness body 3 is sequentially inserted into the first... The first positioning wheel 611 and the second positioning wheel 613 are located in the grooves on the first positioning wheel 611 and the second positioning wheel 613, thereby guiding and positioning the wire harness body 3. Since the first positioning wheel 611 and the second positioning wheel 613 are provided with grooves corresponding to the wire harness body 3, when the number of wire harness bodies 3 to be processed increases and the first positioning wheel 611 and the second positioning wheel 613 need to be replaced, a hexagonal wrench is inserted into the groove of the locking block 802 and pressed down, so that the locking block 802 is no longer engaged with the locking groove 803 on the slider 801. At this time, the locking block 802 abuts against the second spring. Spring 804 retracts and pulls the mounting bracket 610 outward. The mounting bracket 610 drives the slider 801 to slide out of the housing 1, which facilitates the replacement of the mounting bracket 610 with the first positioning wheel 611 and the second positioning wheel 613 of the specifications corresponding to the number of wire harness bodies 3 to be processed. When the diameter of the wire harness body 3 to be processed changes, the lead screw 614 is rotated. The lead screw 614 drives the slide plate 612 to slide on the mounting bracket 610. The slide plate 612 drives multiple second positioning wheels 613 to press down on the wire harness body 3, thereby playing a good positioning role for the wire harness body 3.When it is necessary to adjust the distance between the drive roller 401 and the driven roller 402, the first hydraulic rod 406 is activated. The first hydraulic rod 406 drives the two sets of driven rollers 402 to slide downward through the connecting frame 407, so that the driven rollers 402 touch the wire harness body 3 downward. Then, the two motors 405 are activated. The two motors 405 drive the two sets of drive rollers 401 to rotate through the belt 404. The rotation of the drive rollers 401 drives the wire harness body 3 to move, so that friction is generated between the wire harness body 3 and the driven rollers 402, and the driven rollers 402 are driven to rotate. Thus, the wire harness body 3 is moved by the cooperation of the drive rollers 401 and the driven rollers 402. When the wire harness body 3 passes through the cutting assembly 2 and its end is located at the set of drive rollers 401 and the driven rollers 402 responsible for feeding, the wire harness body 3 is moved. When the wire harness body 3 is cut by the cutting blade on the moving roller 402, the second hydraulic rod 604 is activated. The second hydraulic rod 604 extends and drives the connecting rod 607 to rotate towards the cutting assembly 2 via the second rotating shaft 606. The connecting rod 607 drives the fixing frame 603 to rotate on the first rotating shaft 602. At the same time, the fixing frame 603 drives the wire tube 608 to rise towards one end of the cutting assembly 2. The wire tube 608 provides both guidance and positioning for the wire harness body 3, and also provides good protection for the wire harness body 3. At this time, the driving roller 401 and the driven roller 402, which are responsible for feeding, rotate in opposite directions, driving the cut wire harness body 3 to move towards the cutting assembly 2. The cutting assembly 2 then strips the wire from the end of the wire harness body 3.
