DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] The prior art often uses manual methods to select the bottom line in the wire harness, which has low work efficiency. However, the present invention provides a wire harness clamping device, which presses the wire harness into a lantern shape and then clamps the wire, that is, the required ground wire, through a wire clamping assembly.

[0029] A wire harness clamping device, comprising a wire pressing part and a wire clamping part, such as Figure 1-Figure 7As shown, the wire pressing part specifically includes a twisting and pressing harness base 1, a twisting and pressing harness module 2 and a limiting module 3 arranged on the twisting and pressing harness base 1, the limiting module 3 is used to clamp the wire harness to be processed and keep one end of the wire harness to be processed stationary, the twisting and pressing harness module 2 includes a first sliding component 21 installed on the twisting and pressing harness base 1, and a wire twisting component 22 slidably connected to the first sliding component 21, the first sliding component 21 can drive the wire twisting component 22 to press the wire harness toward the limiting module 3 until the wire harness is pressed into a lantern shape, the wire twisting component 22 includes an electric finger 222, a first clamping jaw component 221 installed at one end of the electric finger 222 and a rotating motor 223 at the other end, the rotating motor 223 is used to drive the first clamping jaw component 221 to twist the wire harness.

[0030] like Figure 7 As shown, the twisting and pressing wire harness base 1 can be a square support, or it can be composed of two support columns arranged between the upper panel and the lower panel, and the upper panel is used to install the limit module 3 and the twisting assembly 22. The limit module 3 is mainly used to fix the wire harness, because when processing the wire harness, the wire harness needs to be twisted and pressed into a lantern shape, and one end of the wire harness to be processed needs to be kept stationary, and the stationary mentioned here means neither rotating nor moving. When the wire twisting assembly 22 twists the wire harness, one end of the wire harness needs to remain stationary, so the limit module 3 is used to clamp the critical position of the non-processing end and the processing end of the wire harness to be processed, and then the wire twisting assembly 22 starts to twist the wire harness. The wire twisting assembly 22 performs the first twist according to the winding direction of the wire harness. If the wire harness is wound clockwise, the wire harness is twisted clockwise, that is, the original winding direction of the wire harness is pre-tightened, because if the wire harness is not pre-tightened, the wire harness is directly twisted counterclockwise. When the wire harness already shows signs of loosening, it is twisted counterclockwise so that the wire harness is twisted into a wire harness wound in another direction again. The wire harness is not opened, so the wire harness needs to be pre-tightened first, and then the wire harness is twisted in the opposite direction to loosen the wire harness. The first clamping jaw assembly 221 in the wire twisting assembly 22 can complete the pre-tightening and loosening of the wire harness.

[0031] In a preferred embodiment, in order to better complete the pre-tightening of the wire harness in the original winding direction, the twisting assembly 22 also includes a second clamping jaw assembly 224, and the second clamping jaw assembly 224 includes an upper clamping block 2241, a lower clamping block 2242, and a second power assembly 2243 that drives the upper clamping block 2241 and the lower clamping block 2242 to close and clamp the wire harness. When the upper clamping block 2241 and the lower clamping block 2242 are closed, a columnar second cavity for clamping the wire harness is formed. The first clamping assembly 221 includes a left clamping block 2211 and a right clamping block 2212, and the left clamping block 2211 and the right clamping block 2212 also form a first cavity for clamping the wire harness, the inner wall of the first cavity is not smooth and the inner wall of the second cavity is not smooth, but the inner wall of the first cavity is rougher than the inner wall of the second cavity, that is, the second cavity is more suitable for pre-tightening the wire harness. If only the first clamping jaw assembly 221 is used to pre-tighten the wiring harness, the wiring harness may be too forceful when rotating, and the wiring harness may be easily damaged when rotating in the opposite direction. Therefore, the second clamping jaw assembly 224 in the twisting assembly 22 is required to pre-tighten the wiring harness in the original direction. The second power assembly 2243 is a second clamping jaw assembly 224 cylinder, and the second clamping jaw assembly 224 cylinder drives the upper clamping block 2241 and the lower clamping block 2242 to clamp the wiring harness. The clamping method is: when the upper clamping block 2241 and the lower clamping block 2242 are closed, a cylindrical second cavity will be formed. The diameter of this second cavity is slightly smaller than the wiring harness. The inner wall of the second cavity is smoother than the inner wall of the first cavity, so that the clamping force of the wiring harness is not as strong as the first clamping jaw assembly 221, so the damage to the wiring harness caused by repeated twisting will not be very large. In order to enhance the effect of pre-tightening the wiring harness, a thread or a plurality of protrusions that enhance friction are provided on the inner wall of the second cavity to increase the friction between the inner wall of the second cavity and the wiring harness. The first clamping jaw assembly 221 includes a left clamping block 2211 and a right clamping block 2212, and a first power assembly 2213 that drives the left clamping block 2211 and the right clamping block 2212 to clamp the wire harness. The first power assembly 2213 is a linear pneumatic finger, and the linear pneumatic finger includes two fingers for driving the left clamping block 2211 and the right clamping block 2212 to open and close. The left clamping block 2211 and the right clamping block 2212 are closed to clamp the wire harness.

[0032] The second power assembly 2243 is a cylinder of the second clamp assembly 224 installed on the side wall of the electric finger 222. Since the second clamp assembly 224 clamps the wire harness in the up and down directions, in order to facilitate the installation of the first clamp assembly 221, the clamping blocks of the second clamp assembly 224 are arranged on the left and right sides, and a cavity is formed when the left clamping block 2211 and the right clamping block 2212 are closed, which is the first cavity. The diameter of the cavity is much smaller than the diameter of the second cavity, and the wire harness can be completely clamped, and the force applied to the wire harness will be greater.

[0033] like Figure 6As shown, in a preferred embodiment, the limiting module 3 includes a bracket arranged on the twisting and pressing harness base 1, a transmission mechanism 32 installed on the bracket, and a third clamping jaw assembly 31 installed on the transmission mechanism 32 and driven to open and close by the transmission mechanism 32. The third clamping jaw assembly 31 includes a left clamping jaw 311 and a right clamping jaw 312; the transmission mechanism 32 includes a power source, a fixed block 321, a first transmission rod 323, a second transmission rod 324, a vertical slider, a vertical slide rail 327, a third transmission rod 325 and a fourth transmission rod 326; wherein a power rod 322 extends from the lower part of the fixed block 321, one end of the first transmission rod 323 and the second transmission rod 324 are respectively connected to the power rod 322, the other ends of the first transmission rod 323 and the second transmission rod 324 are respectively hinged to one end of the third transmission rod 325 and the fourth transmission rod 326, the other ends of the third transmission rod 325 and the fourth transmission rod 326 are respectively hinged to the vertical slider, the vertical slider slides on the vertical slide rail 327 and is fixedly connected to the power source.

[0034] The specific structure of the limiting module 3 is as follows: the power source is a cylinder or other linear motion structure on which a linear slide rail is arranged as a vertical slide rail 327. For example, the power source is a vertically arranged cylinder, and a slide groove is arranged on the surface of the cylinder as the vertical slide rail 327. The fixed block 321 is fixed to the twist and press harness base 1 through a bracket. The vertical slide rail 327 can be driven by the power source through the structure of the slide rail and the cooperation of the fixed block to complete the up and down sliding of the vertical slide rail. A power rod 322 extends out of the fixed block to install the first transmission rod 323 and the second transmission rod 324. As shown in the figure, the right end of the power rod 322 is hinged to one end of the first transmission rod 323, and the left end of the power rod 322 is hinged to one end of the second transmission rod 324; then, one end of the fourth transmission rod 326 is hinged to the end of the first transmission rod 323 away from the power rod 322, and one end of the second transmission rod 324 away from the power rod 322 is hinged to one end of the third transmission rod 325, and one end of the fourth transmission rod 326 away from the first transmission rod 323 is hinged to the vertical slider. 25 one end away from the second transmission rod 324 is hinged to the vertical slider, the fourth transmission rod 326 and the third transmission rod 325 coincide with the hinge point of the vertical slide rail, the vertical slide rail is hidden between the fixed block 321 and the vertical slide rail 327, when the wiring harness is clamped, the first transmission rod 323, the second transmission rod 324, the third transmission rod 325, and the fourth transmission rod 326 form an isosceles triangle with the first transmission rod 323 and the second transmission rod 324 as the base; when the wiring harness is released, the first transmission rod 323, the second transmission rod 324, the third transmission rod 325, and the fourth transmission rod 326 form a quadrilateral.

[0035] The first sliding assembly 21 includes a base slider 211 sleeved on the wire twisting assembly 22 , a slider rail 212 slidably connected to the base slider 211 , and a first sliding assembly cylinder 213 driving the base slider 211 to move back and forth linearly on the slider rail 212 .

[0036] The device also includes a harness fixing assembly 4 for installing the harness to be processed, the harness fixing assembly 4 includes a base 41 and a clip arranged on the base 41 for fixing the harness, and the harness fixing assembly 4 can install at least two harnesses.

[0037] The specific operation of the pressing part includes the following steps:

[0038] S1, fixing the processed wire harness on the wire harness fixing component 4;

[0039] S2, driving the limit module 3 to clamp one end of the processing wiring harness;

[0040] S3, driving the wire twisting assembly 22 to clamp the other end of the wire harness to be processed;

[0041] S4, driving the rotating motor 223 to drive the wire twisting assembly 22 to twist the wire harness, and at the same time the first sliding assembly 21 drives the wire twisting assembly 22 to press the wire harness toward the limiting module 3 until the wire harness is pressed into a lantern shape.

[0042] The steps for twisting the wire harness to compress the wire harness into a lantern shape are as follows:

[0043] S401, driving the second clamping jaw assembly 224 in the wire twisting assembly 22 to clamp the wire harness;

[0044] S402, driving the rotating motor 223 to drive the second clamping jaw assembly 224 to twist the wire harness, wherein the twisting direction is the winding direction of the wires in the wire harness;

[0045] S403, driving the second clamping jaw assembly 224 to release the wire harness, and then driving the first clamping jaw assembly 221 in the wire twisting assembly 22 to clamp the wire harness;

[0046] S404, driving the rotating motor 223 to rotate in the opposite direction, and at the same time driving the first sliding assembly 21 to drive the first clamping claw assembly 221 to press the wire harness toward the limiting module 3 until the wire harness is pressed into a lantern shape.

[0047] like Figure 8-Figure 11As shown, the wire clamping part of the device specifically includes a wire clamping base 5, a wire clamping base adapter plate 6, and a wire clamping assembly 7 installed on the wire clamping base 5 through the wire clamping base adapter plate 6; the wire clamping assembly 7 includes a wire clamp 71, a power platform that is tilted and used to drive the wire clamp 71 to clamp the wire, and a power assembly 73 that drives the power platform to move; the power assembly 73 includes a driving member mounting plate 731 that is slidably connected to the power platform, a first linear driving member 732 that is vertically connected to the power platform and drives the power platform to slide on the driving member mounting plate 731, and a second linear driving member 733 that is installed on the wire clamping base adapter plate 6 and abuts against the driving member mounting plate 731 and is tilted in the same direction as the power platform; the first linear driving member 732 is used to drive the power platform to move linearly in the vertical direction; the second linear driving member is used to drive the power platform to move linearly in the tilted direction. The power platform is slidably connected to the driving member mounting plate 731, and the power platform is used to drive the wire clamp 71 to open and close the pneumatic clamping finger 72, wherein the finger of the pneumatic clamping finger 72 is the wire clamp claw.

[0048] The pneumatic clamping finger 72 is tilted to mean that the angle between the pneumatic clamping finger 72 and the horizontal plane is acute, and the acute angle can be 30°, 45° or 60°, which can be designed according to the needs of the present invention. The wire clamp jaw is used to drive the opening and closing of the wire clamp 71. When the wire clamp 71 is opened, the wire clamp 71 is extended to both sides of the target wire in the wire harness. For example, if the target wire is a ground wire, the wire clamp 71 is extended to both sides of the ground wire, and then the wire clamp jaw clamps the wire clamp 71, and the tip of the wire clamp 71 is closed to clamp the ground wire.

[0049] The power assembly 73 includes a driver mounting plate 731 slidably connected to the pneumatic clamping finger 72, a first linear driver 732 slidably connected to the upper end surface of the driver mounting plate 731 and vertically connected to the pneumatic clamping finger 72, and a second linear driver 733 mounted on the clamping base adapter plate and abutting against the driver mounting plate 731 and tilted in the same direction as the pneumatic clamping finger 72. The second linear driver tilted in the same direction here means that the overall linear direction of the second linear driver 733 is in a straight line with the overall direction of the pneumatic clamping finger 72, so the overall directions of the driver mounting plate 731, the pneumatic clamping finger 72, and the second linear driver 733 are in a straight line; the driver mounting plate is a rectangular plate, the upper surface of the driver mounting plate 731 is slidably installed with the first linear driver 732, and the lower surface of the driver mounting plate is fixedly installed with the second linear driver 733. The first linear driver 732 is used to drive the clamping jaw to move in the vertical direction; the second linear driver 733 is used to drive the clamping jaw to move in a straight line along the inclined direction.

[0050] The first linear driving member 732 includes a first adapter plate 7321 slidably connected to the driving member mounting plate 731, and a first linear cylinder 7322 connected to the first adapter plate 7321 and used to drive the first adapter plate 7321 to move vertically. When the first adapter plate 7321 is installed with the pneumatic clamping finger 72, the mounting portion of the first adapter plate 7321 is sleeved on the pneumatic clamping finger 72, and a portion of the side wall of the first adapter plate 7321 extends vertically downward, which is the mounting plate of the first linear cylinder 7322, and the first linear cylinder 7322 is fixed to the mounting plate of the first linear cylinder 7322. When the first linear cylinder 7322 reciprocates up and down, it drives the pneumatic clamping finger 72 to move up and down; for example, the first linear power cylinder moves vertically upward, driving the first linear cylinder 7322 mounting plate to move upward, and the first linear cylinder 7322 mounting plate drives the overall first adapter plate 7321 to move upward. Since the pneumatic clamping finger 72 and the first adapter plate 7321 are fixed and the pneumatic clamping finger 72 is slidably connected to the drive member mounting plate 731, the upward movement of the first linear cylinder 7322 will cause the first adapter plate 7321 to drive the pneumatic clamping finger 72 to slide obliquely upward on the upper surface of the drive member mounting plate 731 as shown in the figure. The oblique upward direction is the inclination direction of the upper surface of the drive member mounting plate 731 in the figure. It can also be seen from the structure in the figure that when the pneumatic clamping finger 72 slides in the inclination direction of the plane, the pneumatic clamping finger 72 with the wire clamp 71 will perform a fine adjustment and rise.

[0051] The second linear drive member 733 includes a second linear cylinder 7331 whose fixed end is mounted on the clamping base adapter plate, and a second adapter plate 7332 mounted on the output end of the second linear cylinder 7331. The fixed end of the first linear cylinder is fixed on the second adapter plate 7332. The second adapter plate 7332 is arranged at the output end of the second linear cylinder 7331 to ensure that the first linear drive member 732 can be driven to move in the coarse position adjustment link on the pneumatic clamping finger 72, so as to facilitate the subsequent fine adjustment of the pneumatic clamping finger 72 by the first linear drive member 732.

[0052] The fixed end of the first linear cylinder 7322 of the first linear drive member 732 can also be on a separate bracket, and the bracket can be provided with a slide rail in the X and Y directions. A lifting structure is provided on the bracket and is fixedly connected to the wire clamping claw of the wire clamping base, the slide rails in the X and Y directions and the lifting structure that is adjustable in the Z direction. The lifting structure moves with the movement of the pneumatic clamping finger 72, and then fine-tuning of the pneumatic clamping finger 72 in the Z direction is performed.

[0053] The wire clamp jaws include a clamping finger arranged on a pneumatic clamping finger 72, and the pneumatic clamping finger 72 can drive the clamping finger to open and close. The clamping finger can be composed of two rectangular blocks with an obtuse angle, and the pneumatic clamping finger 72 can drive the clamping finger to close and open. The specific driving method can be that the pneumatic clamping finger 72 is a two cylinder structure, the output end of one cylinder is connected to the left clamping piece, and the output end of the other cylinder is connected to the right clamping piece. Of course, this wire clamping base can also be a screw nut structure, and the clamping finger is provided with a threaded hole and is sleeved on two opposite screws, and the screw rotates to drive the clamping finger to clamp or loosen.

[0054] The driver mounting plate 731 is provided with a groove slide rail, and the pneumatic gripper finger 72 is provided with a protrusion that slides on the groove slide rail. In order to allow the pneumatic gripper finger 72 to slide on the mounting plate, a slide rail structure can be set at both ends, and preferably a slide groove, that is, a groove slide rail, is set on the mounting plate.

[0055] The wire clamp 71 includes a left clamp 711 and a right clamp 712. The left clamp 711 and the right clamp 712 include a clamp root installed on the pneumatic clamp finger 72 and a tip for clamping the wire harness. The opening and closing of the clamp jaws is used to drive the opening and closing of the left clamp 711 and the right clamp 712. As shown in the figure, the wire clamp 71 is provided with two groups. Due to work needs, when two groups of wires, that is, two groups of ground wires, need to be removed, the two groups of wire clamps 71 can be installed on the lower surface of the pneumatic clamp finger 72 at the same time, that is, the clamps present an L shape from the root to the tip. The left clamp 711 and the right clamp 712 can also be arranged in a cross-arrangement. Here, the cross-arrangement refers to an "×" arrangement. When the clamp jaws are closed, the upper part of the intersection is clamped, so that the left clamp 711 and the right clamp 712 clamp the wire group.

[0056] The device also includes a slide rail drive assembly 8, which is used to move the wire clamping base adapter plate 6 on the wire clamping base 5; the slide rail drive assembly 8 includes a fixed slide rail 81, a slider 82 connected to the adapter plate and sliding on the fixed slide rail, and a linear drive cylinder 83 that drives the slider to slide.

[0057] When the device is in motion, it first drives the second linear cylinder 7331 to drive the wire clamp jaw to make a rough adjustment in a position, so that the wire clamp jaw moves to the bottom of the wire harness and is very close to the wire harness in the vertical direction, and then drives the first linear cylinder to move vertically upward so that the wire clamp jaw drives the wire clamp 71 to penetrate into the gap between the wires, and the pneumatic clamping fingers 72 close the clamping fingers so that the wire clamp 71 clamps the wires; then drives the second linear cylinder 7331 to move obliquely downward, the target wire is pulled out, and then the second linear cylinder 7331 moves downward to completely pull down the pulled out wire to separate it from the wire harness.

[0058] The specific operation of the clamping part includes the following steps:

[0059] S5, driving the second linear cylinder 7331 to drive the power platform to move upwards until the wire clamp 71 on the power platform moves to the bottom of the wire harness to be processed;

[0060] S6, driving the first linear cylinder 7322 to drive the power platform to move vertically upward until the left clamping piece 711 and the right clamping piece 712 of the wire clamp penetrate into the wire harness;

[0061] S7, the power platform drives the left clamping piece 711 and the right clamping piece 712 to clamp the wire;

[0062] S8, driving the second linear cylinder 7331 to drive the power platform to tilt downward and drive the wire clamp 71 to pull out the clamped wire;
