Description

Technical Field

[0001] The invention relates to the technical field of wire harness processing, in particular to a threading device for positioning a wire harness in automobile wire drawing processing. Background Art

[0002] A large number of lines are used in the production process of automobiles. Before installing the lines, a wire threading machine will be used to pre-install the wires, and then the installed wire harness will be installed in the circuit board of the automobile. The existing wire threading machine will install a metal clip sleeve on the conductive end during the process of threading the wires, and then fix the wires through a clamping device, and then insert the wires installed with the metal clip sleeve into the wire harness frame, and cooperate with the clip pieces in the wire harness frame by clipping, thereby completing the entire installation process, and repeating the above steps to complete the installation of the entire wire harness frame.

[0003] However, the wire harness threading machine in the prior art cannot be effectively applied to the processing of wire harnesses with thicker diameters. For example, a wire harness positioning threading machine for automobile wire drawing processing with publication number CN114744553B has a magnetic suction device including a stroke block, a fixed sleeve is fixedly installed on one side of the stroke block, a contact copper sheet II is fixedly installed at a position near one end of the fixed sleeve, the axis of the contact copper sheet II and the axis of the contact copper sheet I are located on the same center line, and a solenoid is fixedly installed at the other end of the fixed sleeve, and the solenoids are connected by wires. The solenoid generates a magnetic field, thereby attracting the metal clamping sleeve at the end of the wire, and under this action, the wire will remain in a straight state, so that the wire can be aligned with the magnetic suction tube during the clamping process, so that it can be stably inserted, avoiding the problem that one end of the wire in the traditional equipment is too heavy due to the installation of the metal clamping sleeve, so that the clamping position is far away from one end, causing the wire to bend and make it unable to align with the magnetic suction tube, resulting in the inability to thread the wire correctly, and improving the stability of the operation of the device;

[0004] Although this patent application enables the wire to be aligned with the magnetic suction tube so that it can be inserted stably, when processing some wires with thicker diameters, the wire core exposed after the wire end is peeled will slightly expand to the surroundings due to the constraint of the wireless skin, which will cause the metal clamping sleeve to be unable to be smoothly connected to the wire core exposed at the wire end.

[0022] Fourthly, in the present invention, springs are provided on the right sides of the second clipping plate and the third clipping plate. When the first clipping plate moves to the left, the spring will exert a certain resistance on the right sides of the second clipping plate and the third clipping plate, so that the second clipping plate and the third clipping plate will not directly separate from the wire core in a natural state, but will only be driven to move to the right side under the traction of the slider on the first clipping plate on the slide groove, thereby avoiding the wire core from being unable to be constrained and shaped normally.

[0034] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] The embodiment of the present invention provides a threading device for positioning a wiring harness for automobile wire drawing processing, comprising a processing table 1, a wire core sleeve assembly 2 and a wire core clamping assembly 3, wherein the wire core sleeve assembly 2 is arranged on the processing table 1, and the wire core sleeve assembly 2 can sleeve and constrain the wire core exposed after the wire end is stripped, and the wire core clamping assembly 3 is located on the opposite side of the wire core sleeve assembly 2, and the wire core clamping assembly 3 and the wire core constraint working end on the wire core on the wire core sleeve assembly 2 are arranged facing each other, and the first driving mechanism 4 and the second driving mechanism 5 that can drive the wire core sleeve assembly 2 and the wire core clamping assembly 3 to move horizontally are respectively arranged on the wire core sleeve assembly 2 and the wire core clamping assembly 3, and the first driving mechanism 4 and the second driving mechanism 5 are both driving electric cylinders, and can also be other devices with a linear trajectory driving function, and the driving electric cylinder is controlled by an operation instruction through a control unit;

[0036] During processing, the operating control unit generates a pulling force to issue an operation command to the second driving mechanism 5, so that the second driving mechanism 5 drives the wire core clamping assembly 3 to move to the right, so that the distance between the wire core clamping assembly 3 and the wire core sleeve assembly 2 is expanded to facilitate the placement of the wire;

[0037] The stripped wire is then placed on the processing table 1, and the exposed wire core portion of the wire end is positioned into the constrained working end of the wire core sleeve assembly 2, and then the second driving mechanism 5 is started to move the wire core clamping assembly 3 toward the wire core sleeve assembly 2, and drive and extrude it from the right side of the wire core, and cooperate with the wire core sleeve assembly 2 to wrap the exposed wire core of the wire end, and maintain it for a period of time so that the slightly expanded part of the front end of the wire core can be shaped, and then the first driving mechanism 4 and the second driving mechanism 5 are started synchronously, so that the wire core sleeve assembly 2 and the wire core clamping assembly 3 are gradually separated from the wire core, so that the front end of the wire core is gradually exposed to facilitate the metal clamping sleeve to be sleeved on the wire core end, so that the shaped wire core can be returned to be smoothly placed in the metal clamping sleeve.

[0038] In a further preferred embodiment, the wire core socket assembly 2 comprises a first socket plate 21, a second socket plate 22 and a third socket plate 23, and the first socket plate 21, the second socket plate 22 and the third socket plate 23 have the same structure;

[0039] Taking the first socket plate 21 as an example, the first socket plate 21 is a rectangular block structure as a whole, and a groove 24 for placing the wire core is provided on the first socket plate 21, and the groove 24 passes through the right side of the first socket plate 21, so that the right side of the groove 24 on the first socket plate 21 is open;

[0040] The first sleeve plate 21, the second sleeve plate 22 and the third sleeve plate 23 are arranged closely on the processing table 1 in sequence, that is, the second sleeve plate 22 is located between the first sleeve plate 21 and the third sleeve plate 23, the first sleeve plate 21, the second sleeve plate 22 and the third sleeve plate 23 are all in transverse sliding cooperation with the processing table 1, the output end of the first driving mechanism 4 is arranged toward the first sleeve plate 21, and the output end of the first driving mechanism 4 is fixedly connected to the left side of the first sleeve plate 21;

[0041] When the wire core socket assembly 2 composed of the first socket plate 21, the second socket plate 22 and the third socket plate 23 is in use, after the first socket plate 21, the second socket plate 22 and the third socket plate 23 are combined and spliced ​​together, the groove 24 area between them can form a space for wrapping the wire core. During operation, the wire core part needs to be inserted into the groove 24 from the right side of the first socket plate 21, the second socket plate 22 and the third socket plate 23. When inserted, the wire core will be squeezed and guided by the inner wall of the groove 24 on the first socket plate 21, the second socket plate 22 and the third socket plate 23, so that the part where the wire core contacts the inner wall of the groove 24 of the first socket plate 21, the second socket plate 22 and the third socket plate 23 is shaped, so as to perform preliminary shaping treatment on the wire core.

[0042] In a further preferred embodiment, the inner sides of the right ends of the first sleeve plate 21, the second sleeve plate 22 and the third sleeve plate 23 after the groove 24 is set are provided with inclined surfaces 25, so that the right openings of the groove 24 areas of the first sleeve plate 21, the second sleeve plate 22 and the third sleeve plate 23 are in an expanded state;

[0043] When the wire core is placed into the groove 24 area on the first socket plate 21, the second socket plate 22 and the third socket plate 23, the design of the inclined surface 25 on the inner side of the right ends of the first socket plate 21, the second socket plate 22 and the third socket plate 23 after the groove 24 is set can expand the right side opening of the first socket plate 21, the second socket plate 22 and the third socket plate 23, so that the wire core with a slightly unfolded end can be smoothly placed in the groove 24 of the first socket plate 21, the second socket plate 22 and the third socket plate 23, and be shaped under the guidance of the inner wall of the groove 24.

[0044] In a further preferred embodiment, the wire core clamping assembly 3 comprises a first clamping plate 31, a second clamping plate 32 and a third clamping plate 33, and the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 have the same structure;

[0045] Taking the first clamping plate 31 as an example, the first clamping plate 31 is a rectangular block structure as a whole. An arc groove 34 for clamping and constraining the wire core is arranged on the left side of the first clamping plate 31. The arc groove 34 can wrap the wire core just after being spliced ​​with the groove 24 on the first sleeve plate 21.

[0046] In a further preferred embodiment, the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 are arranged closely in sequence on the processing table 1, that is, the second clamping plate 32 is located between the first clamping plate 31 and the third clamping plate 33, and the first clamping plate 31 is arranged correspondingly to the first sleeve plate 21, the second clamping plate 32 is arranged correspondingly to the second sleeve plate 22, and the third clamping plate 33 is arranged correspondingly to the third sleeve plate 23;

[0047] The first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 are all in transverse sliding cooperation with the processing table 1, the output end of the second driving mechanism 5 is arranged toward the first clamping plate 31, and the output end of the second driving mechanism 5 is fixedly connected to the right side of the first clamping plate 31;

[0048] When the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 gradually move toward the wire core socket assembly 2, the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 can be inserted from the right area of ​​the groove 24 on the corresponding first socket plate 21, the second socket plate 22 and the third socket plate 23. During the insertion process, the arc groove 34 on the left side of the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 can drive and squeeze the wire core from the right side, and move the wire core to the first socket assembly 2. The wire core is driven into the groove 24 area of ​​the connecting plate 21, the second connecting plate 22 and the third connecting plate 23 until the wire core is in a stopped state. At this time, the arc groove 34 area on the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33 can cooperate with the groove 24 area of ​​the first connecting plate 21, the second connecting plate 22 and the third connecting plate 23 to wrap and extrude the surrounding of the wire core, so as to shape the wire core with the slightly unfolded end, so that the wire core can return to be smoothly installed by the metal clamping sleeve.

[0049] In a further preferred embodiment, sliders 26 are fixedly provided on the rear sides of the first sleeve plate 21, the second sleeve plate 22 and the third sleeve plate 23, wherein slide grooves 27 with transverse straight track are provided at positions corresponding to the sliders 26 on the second sleeve plate 22 and the third sleeve plate 23, the slider 26 on the rear side of the first sleeve plate 21 extends into the slide groove 27 on the second sleeve plate 22, and the slider 26 on the rear side of the second sleeve plate 22 extends into the slide groove 27 on the third sleeve plate 23.

[0050] In a further preferred embodiment, the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 are all fixedly provided with sliders 26 on their rear sides, wherein the positions of the second clamping plate 32 and the third clamping plate 33 corresponding to the sliders 26 are provided with slide grooves 27 with transverse straight track, the slider 26 on the rear side of the first clamping plate 31 extends into the slide groove 27 on the second clamping plate 32, and the slider 26 on the rear side of the second clamping plate 32 extends into the slide groove 27 on the third clamping plate 33;

[0051] After the wire core is shaped, when the metal clamping sleeve is sleeved on the end of the wire core, the first driving mechanism 4 and the second driving mechanism 5 can be started to drive the corresponding first sleeve plate 21 and the first clamping plate 31 to move horizontally to the corresponding left and right sides respectively, so that the groove 24 area on the first sleeve plate 21 and the arc groove 34 area on the second clamping plate 32 are respectively separated from the front end of the wire core. At this time, the front end of the wire core is exposed, and the metal clamping sleeve can be sleeved on the front end of the wire core immediately. With the continuous operation of the first driving mechanism 4 and the second driving mechanism 5, the first sleeve plate 21 continues to move to the left side. When moving, the slider 26 on the first sleeve plate 21 will move in the slide groove 27 on the second sleeve plate 22. When the slider 26 contacts the left inner wall of the slide groove 27 on the second sleeve plate 22, the second sleeve plate 22 will be pulled and the second sleeve plate 22 will be driven to move to the left. Then, the slider 26 on the second sleeve plate 22 will pull the left inner wall of the slide groove 27 on the third sleeve plate 23 to continue to drive the third sleeve plate 23 to move to the left, so that after the first sleeve plate 21 is separated from the left side of the wire core, the second sleeve plate 22 and the third sleeve plate 23 will also gradually separate from the wire core.

[0052] When the second driving mechanism 5 is running, the first clamping plate 31 continues to move to the right, and the slider 26 on the first clamping plate 31 moves in the sliding groove 27 on the second clamping plate 32. When the slider 26 contacts the right inner wall of the sliding groove 27 on the second clamping plate 32, the second clamping plate 32 is pulled and the second clamping plate 32 is driven to move to the right. Then, the slider 26 on the second clamping plate 32 pulls the right inner wall of the sliding groove 27 on the third clamping plate 33 to continue to drive the third clamping plate 33 to move to the left, so that the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 are gradually separated from the wire core.

[0053] It can prevent the rear end of the wire core from being unconstrained after the first sleeve plate 21, the second sleeve plate 22, the third sleeve plate 23, the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 are all separated from the wire core in an instant, thereby causing the rear end of the wire core to be deformed due to the extrusion of the wire core when the metal clamping sleeve is sleeved on the end of the wire core, thereby causing the metal clamping sleeve to be unable to be normally sleeved and pushed toward the rear end of the wire core;

[0054] Therefore, by gradually disengaging the first socket plate 21, the second socket plate 22, the third socket plate 23, the first clamping plate 31, the second clamping plate 32 and the third clamping plate 33 from the wire core, the wire core can be gradually exposed from the front end to the rear end, so as to facilitate the gradual insertion of the metal clamping sleeve onto the end of the wire core, and until the metal clamping sleeve can be completely inserted into the end of the wire core.

[0055] In a further preferred embodiment, a spring 6 is provided on the left side of the second sleeve plate 22 and the third sleeve plate 23, and a clamping block 7 is fixedly provided on the left side of the second sleeve plate 22 and the third sleeve plate 23 on the processing table 1. The two ends of the spring 6 on the second sleeve plate 22 and the third sleeve plate 23 are respectively fixedly connected to the clamping block 7 and the corresponding second sleeve plate 22 and the third sleeve plate 23, and under the thrust of the spring 6, the second sleeve plate 22 and the third sleeve plate 23 can be pushed to the right;

[0056] Since the output end of the first driving mechanism 4 is only connected to the first socket plate 21, and the second driving mechanism 5 is only connected to the first clamping plate 31, when the first socket plate 21 moves to the left, the spring 6 will exert a certain resistance on the left side of the second socket plate 22 and the third socket plate 23, so that the second socket plate 22 and the third socket plate 23 will not directly separate from the wire core in a natural state, but will only move to the left side under the traction of the slider 26 on the first socket plate 21 on the slide groove 27, thereby avoiding the wire core from being constrained and shaped normally.

[0057] In a further preferred embodiment, a spring 6 is provided on the right side of the second clamping plate 32 and the third clamping plate 33, and a clamping block 7 is fixedly provided on the processing table 1 at the right side of the second clamping plate 32 and the third clamping plate 33. The two ends of the spring 6 on the second clamping plate 32 and the third clamping plate 33 are respectively fixedly connected to the clamping block 7 and the corresponding second clamping plate 32 and the third clamping plate 33, and under the thrust of the spring 6, the second clamping plate 32 and the third clamping plate 33 can be pushed to the left;

[0058] When the first clip plate 31 moves to the left, the spring 6 will exert a certain resistance on the right side of the second clip plate 32 and the third clip plate 33, so that the second clip plate 32 and the third clip plate 33 will not directly separate from the wire core in a natural state, but will only be driven to move to the right side under the traction of the slider 26 on the first clip plate 31 on the slide groove 27, thereby avoiding the wire core from being unable to be constrained and shaped normally.
