Description

Technical Field

[0001] The present invention relates to the technical field of wire harness terminal insertion, and specifically provides an automobile wire harness terminal insertion tooling. Background Art

[0002] An automobile wire harness is the main network of the automobile circuit. Its main function is to connect various electrical devices of the automobile, enabling current to be transmitted between each component, thereby ensuring the normal operation of the automobile electrical system. To facilitate the connection between the automobile wire harness and each electrical component, terminals need to be inserted into the wire harness.

[0003] When inserting terminals into a wire harness, it is usually completed using insertion tooling. With the cooperation of a mold, the terminal is placed between two molds, and then the operator inserts the wire harness through the mold onto the mold, and cooperates with the mold to insert the terminal onto the wire harness.

[0004] When inserting terminals into a wire harness composed of multiple strands of wires, after the insulation layer of the wire harness is removed, due to the lack of restraint of the insulation layer, the multiple strands of wires will be in a loose state. When inserting the terminal, the phenomenon of reverse threading often occurs, that is, some wires do not enter the terminal. In this case, the external reverse threading may cause a short circuit in the wire harness; usually, when inserting wire harness terminals, it is mostly a batch operation. When inserting the terminal and the wire harness through the mold, precise alignment is required, resulting in low insertion efficiency. During batch insertion operations, the overall processing efficiency will be affected. Summary of the Invention

Detailed implementation manners

[0036] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] As Figure 1 and Figure 2As shown in the figure, an automotive wiring harness terminal insertion tooling includes an installation frame 1. At the inner bottom end of the installation frame 1, there are two symmetrically arranged connecting sleeves 2 for multi-station splicing. On the installation frame 1, there are successively arranged from back to front a positioning mechanism 5 for clamping the wiring harness, a limiting mechanism 4 for limiting the exposed wires of the wiring harness, a pressing mechanism 3 for extruding the terminals, a terminal placement mechanism 7 for placing the terminals, and a gathering mechanism 6 for tightening the exposed wires of the wiring harness.

[0038] As Figure 1 and Figure 3 As shown in the figure, the positioning mechanism 5 includes two symmetrically arranged moving tracks 51 fixedly connected to the installation frame 1. Along the front-back direction, a first electric slider 52 is slidably connected to the moving track 51. On the opposite surfaces of the two first electric sliders 52, there are first linkage sleeves 53 for multi-station splicing. On the upper surfaces of the two first electric sliders 52, a positioning member 54 is commonly arranged.

[0039] As Figure 3 As shown in the figure, the positioning member 54 includes a support cross plate 541 commonly and fixedly connected to the upper surfaces of the two first electric sliders 52. At the lower surface of the support cross plate 541, there are two symmetrically arranged bidirectional elastic telescopic rods 546 in the front-back direction. At the telescopic ends of the bidirectional elastic telescopic rods 546, there is a fixedly connected frame 542. On the two fixedly connected frames 542 distributed in the front-back direction, there is a commonly fixedly connected auxiliary plate 543. The auxiliary plate 543 is slidably matched with the support cross plate 541. On the opposite surfaces of the two auxiliary plates 543, there are two symmetrically arranged connecting sliding rods 545 in the up-down direction. On the two connecting sliding rods 545 arranged in the up-down direction, a limiting and pressing plate 544 is elastically slidably connected along the front-back direction.

[0040] During specific use, first, the staff places the position of the wiring harness with the insulating layer between the two limiting and pressing plates 544 and presses downward. At this time, the two limiting and pressing plates 544 are subjected to forces in the direction of moving away from each other. The limiting and pressing plates 544 push the auxiliary plate 543 to move synchronously. The auxiliary plate 543 drives the telescopic sections of the bidirectional elastic telescopic rods 546 through the fixedly connected frame 542. With the elastic forces of the two bidirectional elastic telescopic rods 546 themselves, a reverse acting force is generated on the auxiliary plate 543, thereby clamping the wiring harness between the two limiting and pressing plates 544. At the same time, it is ensured that one end of the exposed wire of the wiring harness is located on the limiting mechanism 4. Then, the first electric slider 52 drives the wiring harness to move forward on the moving track 51. After the front side of the insulating layer of the wiring harness abuts against the limiting mechanism 4, the movement of the first electric slider 52 is stopped. At this time, the placement work of the wiring harness is completed.

[0041] It should be noted that when multiple tooling fixtures need to work simultaneously, a fixing rod can be inserted between the connecting sleeves 2 on two tooling fixtures, and the fixing rod and the connecting sleeve 2 are limited by a limit bolt to ensure that the two tooling fixtures are relatively fixed. At the same time, a linkage rod is inserted inside the first linkage sleeve 53 so that the support cross plates 541 between multiple tooling fixtures move synchronously. When aligning the wire harnesses on multiple tooling fixtures, the wire harnesses placed on the multiple tooling fixtures are uneven. When the multiple support cross plates 541 move forward synchronously for a certain distance, there will be a situation where the insulating layers of some wire harnesses abut against the limiting mechanism 4, while some wire harnesses have not yet abutted against the limiting mechanism 4. As the support cross plate 541 continues to move, the wire harnesses that abut against the limiting mechanism 4 will generate resistance to the support cross plate 541. At this time, as the support cross plate 541 continues to move, the resistance acts on the limit extrusion plate 544, pushing the limit extrusion plate 544 to slide backward on the connecting slide rod 545. At this time, when the multiple support cross plates 541 continue to move synchronously, the wire harnesses that abut against the limiting mechanism 4 will not hinder the movement of the support cross plate 541. Subsequently, the support cross plate 541 can continue to push the wire harnesses that have not abutted against the limiting mechanism 4 forward until the insulating layers of all wire harnesses abut against the limiting mechanism 4, and at this time, the alignment of all wire harnesses is completed.

[0042] As Figure 1 and Figure 4 shown, the limiting mechanism 4 includes a support plate 42 fixedly connected to the upper surface of the mounting frame 1. A limiting member 41 is arranged on the upper surface of the support plate 42, and a pressing member 43 is jointly arranged on the limiting member 41 and the support plate 42.

[0043] As Figure 4 and Figure 5 shown, the limiting member 41 includes two symmetrically arranged fixing seats 411 fixedly connected to the upper surface of the support plate 42. Two symmetrically arranged first elastic telescopic rods 412 are fixedly connected to the opposite surfaces of the two fixing seats 411. An arc-shaped extrusion block 413 is jointly fixedly connected to the ends of the two front-back distributed first elastic telescopic rods 412 far away from the fixing seats 411. The arc-shaped extrusion block 413 is slidably matched with the support plate 42.

[0044] As Figure 4 and Figure 5 shown, the pressing member 43 includes two symmetrically arranged second electric telescopic rods 436 fixedly connected to the mounting frame 1 and located below the support plate 42. A third linkage sleeve 435 is jointly fixedly connected to the bottom ends of the two second electric telescopic rods 436. A U-shaped pushing frame 432 is fixedly connected to the middle of the upper surface of the third linkage sleeve 435. Two symmetrically arranged sliding plates 434 are slidably connected to the support plate 42 in the left-right direction. A limiting block 433 is fixedly connected to the upper surface of the sliding plate 434.

[0045] As Figure 4 andFigure 5 As shown in the figure, two limit blocks 433 are in one-to-one correspondence and sliding fit with two arc surface extrusion blocks 413. Grooves adapted to the terminals are provided on the front sides of the two arc surface extrusion blocks 413. There is an elastic sliding connection between the limit block 433 and its corresponding fixed seat 411. The opposite surfaces of the two sliding plates 434 are both beveled and correspond to the two vertical sections of the U-shaped pushing frame 432 one by one. Auxiliary rollers are provided at the tops of the two vertical sections of the U-shaped pushing frame 432. Linking ports for multi-station splicing are provided at both the left and right ends of the third linkage sleeve 435.

[0046] During specific use, when the staff places the wire harness on the alignment member 54, at this time, the exposed wire part of the wire harness is located between the two arc surface extrusion blocks 413. The two arc surface extrusion blocks 413 cooperate with the elastic force of the first elastic telescopic rod 412 itself to limit the exposed wire. At the same time, the front end of the insulating layer of the wire harness abuts against the rear surface of the support plate 42. At this time, the secondary limiting work before tightening and gathering the exposed wire of the wire harness starts. The second electric telescopic rod 436 contracts to drive the third linkage sleeve 435 to move upward. The third linkage sleeve 435 pushes the U-shaped pushing frame 432 to move upward synchronously. At this time, the two vertical sections of the U-shaped pushing frame 432 slide upward along the bevel surfaces of the sliding plates 434. With the auxiliary rollers on the vertical sections of the U-shaped pushing frame 432, it can make the sliding between the U-shaped pushing frame 432 and the sliding plates 434 smoother. The U-shaped pushing frame 432 continues to move upward, pushing the two sliding plates 434 to move closer to each other on the support plate 42, driving the two limit blocks 433 to move synchronously to perform secondary clamping and limiting on the exposed wire part of the wire harness located between the two arc surface extrusion blocks 413.

[0047] It should be noted that when multiple toolings are spliced, a linkage rod is inserted between the opposite surfaces of the third linkage sleeves 435 on the two toolings, so that the third linkage sleeves 435 on multiple toolings move synchronously.

[0048] As Figure 1 and Figure 6 shown in the figure, the gathering mechanism 6 includes two symmetrically arranged displacement tracks 64 on the upper surface of the mounting frame 1. A driving member 63 is jointly provided on the front sides of the two displacement tracks 64. A displacement member 62 is jointly provided on the rear sides of the two displacement tracks 64. A gathering member 65 is provided on the rear side of the displacement member 62. An adjusting member 61 is provided on the gathering member 65.

[0049] During specific use, after the secondary clamping and limiting of the bare wires of the wire harness are completed, the displacement member 62 moves backward on the displacement track 64, pushing the gathering member 65 to move to the front side of the arc-shaped extrusion block 413, and then the gathering member 65 is pushed by the adjusting member 61 to clamp on the bare wires of the wire harness. At this time, the displacement member 62 moves forward, and during the movement, the driving member 63 drives the gathering member 65 to rotate, tightening and gathering the bare wires of the wire harness.

[0050] As Figure 6 、 Figure 7 and Figure 8 shown, the gathering member 65 includes a connecting cross brace 652 fixedly connected to the displacement member 62. On the rear side of the upper surface of the connecting cross brace 652, two symmetrically arranged L-shaped mounting plates 653 are fixedly connected. An arc-shaped extrusion plate 651 is elastically hinged on the vertical section of the L-shaped mounting plate 653.

[0051] As Figure 6 and Figure 7 shown, the adjusting member 61 includes a mounting sleeve 612 fixedly connected to the lower surface of the horizontal section of the L-shaped mounting plate 653. A adjusting rod 613 is slidably connected through the upper and lower surfaces of the mounting sleeve 612. An auxiliary roller is provided at the top of the adjusting rod 613, and the auxiliary roller is in rolling cooperation with the corresponding arc-shaped extrusion plate 651. A sliding track 614 is fixedly connected to the rear end of the lower surface of the connecting cross brace 652. A second electric slider 611 is slidably connected to the sliding track 614 in the up and down direction. Synchronization plates 615 are fixedly connected to both the left and right sides of the second electric slider 611. One end of the synchronization plate 615 away from the second electric slider 611 is fixedly connected to the bottom end of the corresponding adjusting rod 613.

[0052] During specific use, when the gathering member 65 is pushed by the adjusting member 61 to clamp on the bare wires, the second electric slider 611 moves upward on the sliding track 614, driving the adjusting rod 613 to move upward on the mounting sleeve 612 through the synchronization plate 615. At this time, the auxiliary roller at the top of the adjusting rod 613 slides upward along the outer arc surface of the arc-shaped extrusion plate 651, pushing the arc-shaped extrusion plate 651 to rotate on the L-shaped mounting plate 653 in the direction close to the bare wires of the wire harness until the arc-shaped extrusion plate 651 is tightly attached to the bare wires of the wire harness. Then the second electric slider 611 remains stationary, and the arc-shaped extrusion plate 651 is limited by the adjusting rod 613.

[0053] As Figure 6 、 Figure 7 and Figure 9As shown in the figure, the driving member 63 includes a connecting sliding sleeve 631 slidably connected to the displacement track 64 in the front-rear direction. The lower surfaces of the two connecting sliding sleeves 631 are fixedly connected together with a mounting cross brace. A driving motor is fixedly mounted on the rear surface of the mounting cross brace. The lower surface of the mounting cross brace is fixedly connected with a linkage box 633. Synchronous spline bushings 632 are rotatably connected to both the left and right sides of the linkage box 633. One end of the synchronous spline bushing 632 close to the linkage box 633 penetrates into the interior of the linkage box 633. A connecting shaft 634 is rotatably connected to the rear surface of the linkage box 633. The front end of the connecting shaft 634 penetrates to the front surface of the linkage box 633 and is fixedly connected to the output shaft of the driving motor. The circumferential surface of the connecting shaft 634 located inside the linkage box 633 is in transmission connection with the synchronous spline bushing 632 through bevel gears. The rear end of the connecting shaft 634 is rotatably connected with a transmission gear 635.

[0054] As Figure 6 , Figure 7 and Figure 8 As shown in the figure, the displacement member 62 includes a third electric slider 623 slidably connected to the displacement track 64 in the front-rear direction. Fourth linkage sleeves 624 are fixedly connected to the opposite surfaces of the two third electric sliders 623. A positioning frame 622 is fixedly connected to the two third electric sliders 623 together. A toothed disc 621 is rotatably connected to the interior of the positioning frame 622. A through hole smaller than the diameter of the toothed disc 621 is formed in the rear surface of the positioning frame 622. A through groove adapted to the transmission gear 635 is formed in the lower surface of the positioning frame 622. The transmission gear 635 passes through the through groove and meshes with the toothed disc 621. A connecting cross brace 652 passes through the through groove in the positioning frame 622 and is fixedly connected to the front surface of the toothed disc 621.

[0055] During specific use, when the two arc-shaped pressing plates 651 clamp on the exposed wires of the wire harness, at this time, the driving motor drives the transmission gear 635 to rotate through the connecting shaft 634. The transmission gear 635 drives the toothed disc 621 to rotate inside the positioning frame 622. The toothed disc 621 drives the two arc-shaped pressing plates 651 to rotate synchronously through the connecting cross brace 652. At this time, the two arc-shaped pressing plates 651 start to rotate to tighten and gather the exposed wires of the wire harness. At the same time, the third electric slider 623 slides forward on the displacement track 64 to tighten and gather the exposed wires of the wire harness from the rear to the front. The connecting sliding sleeve 631 moves synchronously with the third electric slider 623.

[0056] It should be noted that when the driving motor drives the connecting shaft 634 to rotate, the connecting shaft 634 is in transmission through bevel gears inside the linkage box 633 (as Figure 9As shown in the figure, it drives the two synchronous spline bushings 632 on the linkage box 633 to rotate synchronously. When multiple toolings are spliced, a spline shaft is inserted between the opposite surfaces of the synchronous spline bushings 632 on the two toolings, so that the synchronous spline bushings 632 on multiple toolings rotate synchronously, and further the multiple transmission gears 635 rotate synchronously. A linkage rod is inserted between the opposite surfaces of the fourth linkage sleeves 624 on the two toolings, so that the positioning frames 622 on multiple toolings move synchronously.

[0057] As Figure 1 and Figure 6 As shown in the figure, the terminal placement mechanism 7 includes two left - and - right symmetric first electric telescopic rods 72 fixedly connected to the upper surface of the mounting frame 1. An auxiliary telescopic rod 71 is fixedly connected to the upper surface of the mounting frame 1 and in front of the first electric telescopic rod 72. The tops of the front - and - rear distributed auxiliary telescopic rod 71 and the first electric telescopic rod 72 are jointly fixedly connected to a synchronous connection frame 73. A terminal placement box 74 is fixedly connected between the opposite surfaces of the two synchronous connection frames 73. L - shaped limit plates 75 are fixedly connected to the bottom ends of the left and right sides of the terminal placement box 74. A groove adapted to the arc - shaped pressing plate 651 is provided on the front side of the L - shaped limit plate 75. Second linkage sleeves 76 for linking the synchronous connection frames 73 on multiple toolings are arranged on the opposite surfaces of the two synchronous connection frames 73.

[0058] During specific use, as the third electric slider 623 continues to move, when the arc - shaped pressing plate 651 separates from the bare wire of the cable, at this time, the driving motor continues to rotate, driving the two arc - shaped pressing plates 651 to continue rotating and adjusting their positions until the contact points at the ends of the two arc - shaped pressing plates 651 far from the L - shaped mounting plate 653 are in the directly - above position. Then the first electric telescopic rod 72 starts to contract, driving the terminal placement box 74 to move downward. The setting of the auxiliary telescopic rod 71 can make the terminal placement box 74 move more smoothly during the movement. When the terminal placement box 74 moves to the specified position, the first electric telescopic rod 72 stops contracting and keeps the terminal placement box 74 stationary. Then the second electric telescopic rod 436 extends, driving the U - shaped pushing frame 432 to move downward. At this time, the U - shaped pushing frame 432 moves downward along the inclined surface of the sliding plate 434. The thrust received by the sliding plate 434 gradually decreases. Since the limit block 433 is elastically slidably connected to the fixed seat 411, at this time, under the action of the elastic force between the limit block 433 and the fixed seat 411, the limit block 433 is driven to move towards the direction close to the fixed seat 411, releasing the clamping of the limit block 433 on the bare wire of the wire harness.

[0059] Then, the third electric slider 623 moves backward on the displacement track 64. When the arc-shaped extrusion plate 651 moves to the position of the L-shaped limiting plate 75, in cooperation with the groove on the L-shaped limiting plate 75, the two arc-shaped extrusion plates 651 enter between the two L-shaped limiting plates 75 and push the terminal between the two L-shaped limiting plates 75 backward. In cooperation with the exposed wires after being tightened and gathered, the terminal can be smoothly inserted into the exposed wire of the wire harness. The arc-shaped extrusion plate 651 continuously pushes the terminal backward. In cooperation with the grooves on the two arc-shaped extrusion blocks 413, the terminal can smoothly enter between the two arc-shaped extrusion blocks 413. Until the rear end of the terminal fits on the insulating layer of the wire harness, stop pushing the terminal to move, and then start to press the terminal on the wire harness through the pressing mechanism 3.

[0060] It should be noted that after the terminal between the two L-shaped limiting plates 75 is pushed away, under the action of its own gravity, the terminal inside the terminal placement box 74 moves downward, so that a terminal is loaded again between the two L-shaped limiting plates 75. The lower side of the outer circumferential surface of the terminal is limited by the horizontal sections of the two L-shaped limiting plates 75 (as Figure 10 shown). At the same time, the first electric telescopic rod 72 extends and pushes the terminal placement box 74 upward to its original position through the synchronous connection frame 73. When multiple toolings are spliced, a linkage rod is inserted between the opposite surfaces of the second linkage sleeves 76 on the two toolings, so that the second linkage sleeves 76 on multiple toolings move synchronously.

[0061] As Figure 1 and Figure 4 shown, the pressing mechanism 3 includes a bidirectional electric telescopic rod 31 fixedly connected to the inner bottom end of the installation frame 1. Fixedly connected to the left and right telescopic ends of the bidirectional electric telescopic rod 31 are sickle-shaped connecting rods 32, and fixedly connected to the opposite surfaces of the horizontal sections of the two sickle-shaped connecting rods 32 are pressing blocks 33.

[0062] During specific use, after the terminal is inserted into the exposed wire of the wire harness, the bidirectional electric telescopic rod 31 contracts bidirectionally, drives the two pressing blocks 33 to move towards each other through the sickle-shaped connecting rods 32, and clamps the terminal on the exposed wire of the wire harness. At this time, the wire harness terminal insertion work is completed. Then, the bidirectional electric telescopic rod 31 extends to restore the two pressing blocks 33 to their original positions. At this time, the first electric slider 52 moves backward on the moving track 51 to drive the wire harness to move backward synchronously. At this time, the two arc-shaped extrusion blocks 413 generate a squeezing force on the terminal inserted on the wire harness. In cooperation with the first electric slider 52 driving the wire harness to move backward, this is used to check whether the terminal is firmly crimped.

[0063] Then, the wire harness is removed from the support cross plate 541, and the first electric slider 52 continues to move backward to restore the support cross plate 541 to its original position. Since the limit extrusion plate 544 and the connecting slide rod 545 are elastically slidably connected, the limit extrusion plate 544 is restored to its original position under the action of elastic force. At the same time, the second electric slider 611 moves downward on the sliding track 614, driving the adjusting rod 613 to move downward synchronously to restore to its original position. At this time, the adjusting rod 613 no longer exerts a thrust on the arc extrusion plate 651. Since the arc extrusion plate 651 and the L-shaped mounting plate 653 are elastically hinged, the two arc extrusion plates 651 are opened on their corresponding L-shaped mounting plates 653 under the action of elastic force. At this time, the third electric slider 623 continues to move backward, moving the two arc extrusion plates 651 back to the front side of the arc surface extrusion block 413. Repeating the above steps can perform the next wire harness terminal insertion operation.

[0064] As Figures 1 - 10 shown, the working principle is as follows: In specific use, first, the staff places the wire harness on the alignment member 54, and at the same time places the exposed wire part of the wire harness between the two limit members 41. The exposed wire of the wire harness is limited by the limit members 41, and then the position of the wire harness is aligned through the alignment mechanism 5. At this time, the exposed wire of the wire harness is tightened and gathered and gradually moved forward by the gathering member 65 in cooperation with the displacement member 62 and the driving member 63. After the exposed wire of the wire harness is gathered, the first electric telescopic rod 72 contracts to drive the terminal placement box 74 to move downward to the specified position. The displacement member 62 drives the gathering member 65 to move backward, pushing the terminals inside the terminal placement box 74 backward to sleeved on the terminals of the wire harness, and then the terminal is pressed onto the wire harness through the pressing mechanism 3. At this time, the terminal insertion of one wire harness is completed. The wire harness with completed terminal insertion is removed from the alignment mechanism 5, and the above steps are repeated for the next terminal pressing.
