Description

Technical Field

[0001] This invention relates to the field of wire harness cutting technology, and more specifically, to a multi-station cutting device for high-voltage wire harness terminals of new energy vehicles. Background Technology

[0002] Before crimping terminals onto automotive high-voltage wiring harnesses, the insulation at the ends needs to be removed to expose the internal metal conductors. In existing technology, to improve terminal processing efficiency, the cutting and crimping processes are usually integrated. Currently, the cutting step generally involves "installing and positioning the wiring harness to be cut, reaching the cutting station, radial cutting and rotation of the cutter around its axis, and cutter retraction to remove the insulation." After these steps are completed, the exposed metal conductors of the wiring harness are moved to the crimping station to be crimped onto the terminals.

[0003] Currently, cutting tools for insulating sheaths typically consist of an upper cutter and a lower cutter. With each cut, the wear on the blades of these two cutters will differ. Therefore, when the upper and lower cutters re-enter the wire harness radially, the resistance they encounter will differ. Consequently, there is a difference in force at the top and bottom of the cutting point, causing the wire harness end to no longer remain parallel to the axial direction but instead tilt to one side (the side with less force). This results in different thicknesses of the insulating sheath radially at the top and bottom. Thus, while the cutter with greater cutting force has already cut through the insulation layer, the cutter with less cutting force has not yet done so.

[0004] Since the clamping force of the fixture on the wire harness is usually along the radial direction of the wire harness, after the insulation layer is cut off from the end of the wire harness, when the cutter pulls it back to peel off the insulation, the "connecting bridge" formed by the residual insulation layer will pull the wire harness body to move axially. In other words, after each wire harness is cut, its end will no longer be flush due to the above-mentioned axial movement, and it needs to be realigned before pressing, which increases the workload.

[0005] In view of this, we propose a multi-station cutting device for high-voltage wiring harness terminals of new energy vehicles to improve the shortcomings of the existing technology. Summary of the Invention

[0006] This invention provides a multi-station cutting device for high-voltage wiring harness terminals of new energy vehicles, which solves the problem that when the cutter pulls the cut insulation layer back to peel it off, the "connecting bridge" formed by the residual insulation layer will pull the wiring harness body to move axially, that is, the end of the wiring harness will no longer remain flush due to the axial movement of the wiring harness.

[0007] To achieve the above objectives, the multi-station cutting device for high-voltage wiring harness terminals of new energy vehicles includes a base. The top of the base is provided with multiple clamps for mounting the wiring harness to be cut. Each clamp slides along the y-axis. The top of the base is provided with a pair of mounting seats facing one side of the wiring harness to be cut. The two mounting seats facing the wiring harness to be cut form a cutting cavity and slide along the x-axis. The cutting cavity is provided with a drive seat that rotates around the wiring harness axis. A pair of support rods are fixedly connected to the side of the drive seat facing the wire harness, and the end of the support rod away from the drive seat is provided with a cutter that cuts radially into the wire harness; Inside the cutting cavity, a pair of rotating bolts are fixedly connected to the inner circumference of each support rod. The rotating bolts are fixedly connected to the mounting base. A toggle rod is rotatably connected between the two rotating bolts at the same height. A limit bracket is fixedly connected to the end of the toggle rod away from its own axis of rotation. The inner sides of the two limit brackets slide against the outer surface of the wire harness to be cut. When the inner side of the limit bracket is not pressed against the outer surface of the wire harness, the limit bracket rotates unidirectionally around its own axis of rotation towards the center of the wire harness. Both of the support rods are fixedly connected to a centripetal protrusion on the side that is close to each other, and both of the actuating rods are fixedly connected to a centrifugal protrusion on the side that is far from each other. The orthographic projection of the centripetal end of the centripetal protrusion on the yOz plane coincides with the orthographic projection of the centrifugal end of the centrifugal protrusion on the yOz plane.

[0008] In the above technical solution, when no external force is applied to the limiting bracket, the limiting bracket can only rotate inward towards the center of the wire harness. When the end of the wire harness extends between the two limiting brackets, the limiting brackets only provide support for the wire harness. When the two cutters radially cut into the insulation layer of the wire harness, the limiting brackets cannot rotate away from the center of the wire harness, thus preventing the wire harness end from skewing due to the difference in cutting force between the two cutters. In other words, under the limitation of the two limiting brackets, the end of the wire harness always remains parallel to the centerline of the cutting cavity, ensuring that the cuts made by the two cutters into the wire harness are in the same vertical plane. When the two cuts are in the same vertical plane, after the cutters rotate and cut with the drive seat, no "connecting bridge" will remain in the insulation layer of the wire harness.

[0009] As the two cutters radially penetrate the wire harness insulation layer, their concentric protrusions continuously press down on the centrifugal protrusions during rotation, causing the two limiting supports to press inwards against the cut edge of the wire harness. Simultaneously, because the pressing of the two limiting supports against the wire harness surface is intermittent, it's as if the two limiting supports are striking the cut edge of the insulation layer. This striking action, through high-frequency micro-impact, disrupts the molecular chain structure of the insulation, reducing its toughness and causing the insulation to break quickly when the cutters penetrate, thus preventing tensile deformation.

[0010] Based on this, both mounting bases have channels on the side of the cutting cavity away from the clamp, and the two channels form a peeling groove. A waste trough is provided on the top of the base below the peeling groove on the side away from the cutting cavity.

[0011] The support rod is provided with a hydraulic rod at the end away from the drive seat. The cylinder of the hydraulic rod is fixedly connected to the support rod, and the piston end of the hydraulic rod is fixedly connected to the cutter. The piston end of the hydraulic rod is distributed radially along the wire harness.

[0012] In another technical solution, a rotating rod is fixedly connected to the end of the actuating rod away from the limiting bracket. The rotating rod is perpendicular to the actuating rod, that is, the rotating rod is the pivot of the actuating rod, and the rotating rod extends out from the inside of the rotating bolt.

[0013] Furthermore, a mounting arm is fixedly connected to the side of the rotating bolt away from the other rotating bolt. A coil spring is sleeved between the inner wall of the mounting arm and the outer wall of the rotating rod. The innermost coil spring is fixedly connected to the outer wall of the rotating rod, and the outermost coil spring is fixedly connected to the inner wall of the mounting arm.

[0014] The centrifugal protrusion is a force-bearing block fixedly connected to the lever, and the force-bearing block is distributed along the outer radial direction of the wire harness.

[0015] In this technical solution, when the force-bearing block is not pressed down by the centripetal protrusion, the limiting bracket remains in non-compressive contact with the outer surface of the wire harness. When the cutter radially cuts into the wire harness insulation layer, even if the cutting forces of the two cutters on the wire harness are different, the actuating rod will not rotate outward under the structural restraint of the coil spring. Furthermore, before the two cutters radially cut into the wire harness, the cutter drives the support rod to rotate, positioning the two cutters at the top and bottom of the wire harness respectively. At the cut, the wire harness is always confined between the two limiting brackets. This prevents the wire harness from tilting to both sides due to uneven force caused by the difference in cutting forces between the two cutters.

[0016] Furthermore, since the two cutters are located at the top and bottom of the wire harness respectively when they cut into it, the concentric protrusion will squeeze the two force blocks inward. As a result, the lever will rotate inward around the axis, and the two limit supports will further press the wire harness near the cut, so that the end of the wire harness remains parallel to the whole wire harness as it is being cut radially by the cutter.

[0017] In addition, the centripetal protrusion is a lever fixedly connected to the support rod, and the lever is distributed along the inner radial direction of the wire harness.

[0018] The outer periphery of the force-bearing block is located on the rotation path of the push block. When the push block rotates with the drive seat, the push block presses the force-bearing block radially along the inner side of the wire harness.

[0019] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: After the cutter radially cuts through the insulation layer of the wire harness, the drive unit drives the cutter to rotate around the axis of the wire harness and perform a circumferential cut on its end. The prying block continuously passes near the force-bearing block, squeezing the force-bearing block inward to clamp the wire harness with two limiting brackets. When the force-bearing block is squeezed by the prying block, the coil spring is stretched and stores elastic potential energy. When the prying block leaves the vicinity of the force-bearing block, the coil spring releases the elastic potential energy to reset the limiting brackets, thereby achieving the effect of the limiting brackets striking the cut end of the wire harness, allowing its insulation layer to completely break away from the overall insulation layer of the wire harness.

[0020] The above settings prevent the cutter from leaving "connecting bridges" when circumferentially cutting the insulation layer of the wire harness. This prevents the wire harness from sliding relative to each other along the x-axis within the fixture due to these "connecting bridges" when the pneumatic system retracts the cutter to remove the insulation. In other words, after each wire harness has been stripped, the exposed metal conductor end remains flush. Subsequent terminal crimping does not require realignment. Attached Figure Description

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-3 Since the clamping force of the fixture on the wire harness is usually along the radial direction of the wire harness, after the insulation layer is cut off from the end of the wire harness, when the cutter pulls the cut insulation layer back to peel off, the "connection bridge" formed by the insulation layer residue will pull the wire harness body to move axially. When crimping terminals onto the exposed metal wire surface later, it is necessary to realign the ends of each wire harness.

[0025] To address the aforementioned problems, the present invention aims to provide a multi-station cutting device for high-voltage wiring harness terminals of new energy vehicles. The cutting device includes a base 100, and a plurality of clamps 110 for mounting the wiring harness to be cut are provided on the top of the base 100. Each clamp 110 slides along the y-axis. A pair of mounting seats 120 are provided on the top of the base 100 facing one side of the wiring harness to be cut. The two mounting seats 120 form a cutting cavity 121 facing the wiring harness to be cut and slide along the x-axis. A drive seat 200 that rotates around the wiring harness axis is provided inside the cutting cavity 121. A pair of support rods 210 are fixedly connected to the side of the drive base 200 facing the wire harness. The end of the support rod 210 away from the drive base 200 is provided with a cutter 220 that cuts into the wire harness radially. A pair of rotating bolts 230 are fixedly connected to the inner circumference of each support rod 210 in the cutting cavity 121. The rotating bolts 230 are fixedly connected to the mounting base 120. A toggle rod 231 is rotatably connected between the two rotating bolts 230 at the same height. A limit bracket 240 is fixedly connected to the end of the toggle rod 231 away from its own axis of rotation. The inner sides of the two limit brackets 240 slide against the outer surface of the wire harness to be cut. When the inner side of the limit bracket 240 is not pressed against the outer surface of the wire harness, the limit bracket 240 rotates unidirectionally around its own axis of rotation towards the axis of the wire harness. When no external force is applied to the limit bracket 240, the limit bracket 240 can only rotate towards the inner side closer to the axis of the wire harness. When the end of the wire harness extends between the two limit brackets 240, the limit bracket 240 only provides support for the wire harness. When the two cutters 220 radially cut into the insulation layer of the wire harness, the limiting support 240 cannot rotate away from the wire harness axis, thus preventing the wire harness end from skewing due to the difference in cutting force between the two cutters 220. In other words, under the limitation of the two limiting supports 240, the wire harness end always remains parallel to the axis of the cutting cavity 121, ensuring that the cuts made by the two cutters 220 into the wire harness are in the same vertical plane. When the two cuts are in the same vertical plane, after the cutters 220 rotate with the drive seat 200 to cut, no "connecting bridge" will remain in the wire harness insulation layer.

[0026] Both support rods 210 have a centripetal protrusion fixedly connected to their respective sides, and both actuating rods 231 have a centrifugal protrusion fixedly connected to their respective sides. The orthographic projection of the centripetal end of the centripetal protrusion in the yOz plane coincides with the orthographic projection of the centrifugal end of the centrifugal protrusion in the yOz plane. When the two cutters 220 radially cut into the wire harness insulation layer, as they rotate with the cutters 220, the centripetal protrusion continuously presses down on the centrifugal protrusion, causing the two limiting supports 240 to press inward at the cut of the wire harness. At the same time, since the pressing of the two limiting supports 240 on the surface of the wire harness is intermittent, that is, the two limiting supports 240 are equivalent to striking the cut of the insulation layer. The striking action destroys the molecular chain structure of the insulation layer through high-frequency micro-impact force, reducing its toughness, so that the insulation layer breaks quickly when the cutter 220 cuts in, avoiding tensile deformation.

[0027] In practice, the wire harnesses to be cut are first placed in the respective clamps 110, ensuring that the cutting positions of each wire harness are flush. Next, a pneumatic system, such as a cylinder, pushes two mounting seats 120 closer to the wire harness, causing the cutting positions at the ends of the wire harness to extend into the cutting chamber 121. Then, the cutter 220 cuts into the insulation layer radially along the wire harness. Once the insulation layer is cut through, the drive seat 200, via the support rod 210, rotates the cutter 220, circumferentially cutting off the insulation layer at the ends of the wire harness. Finally, maintaining the position where the cutter 220 is cutting into the insulation, the pneumatic system drives the cutter 220 to retract, completing the stripping process.

[0028] It should be disclosed that the movement of the wire harness along the y-axis and the movement of the cutter 220 along the x-axis are controlled by a PLC program, and the movement of the wire harness following the clamp 110 along the y-axis is existing technology, which can be achieved by using cylinders, electric actuators, etc., and can be set according to actual needs.

[0029] Insulation waste generated after the wire harness ends are stripped, if it accumulates in the cutting cavity 121 near the wire harness, will interfere with subsequent circumferential cutting of the wire harness. For example... Figure 4 and Figure 5 As shown below, the destination of the insulation waste after the wire harness end is circumferentially cut is disclosed: Both mounting bases 120 have channels on the side of the cutting cavity 121 away from the clamp 110, and the two channels form a peeling groove 122. A waste trough 130 is provided on the top of the base 100 below the peeling groove 122 on the side away from the cutting cavity 121.

[0030] In other words, after the cutter 220 cuts off the insulation layer at the end of the wire harness, the insulation waste falls into the waste tank 130 through the peeling groove 122 under the retraction action of the two cutters 220.

[0031] Next, refer to Figure 5 and Figure 6 The drive structure for the cutter 220 to rotate around the axis of the wire harness and cut radially into the wire harness is described. The cutting cavity 121 is rotatably connected to the gear 201 on the outer periphery of the drive seat 200. Several toothed openings are provided on the outer periphery of the drive seat 200, and the toothed openings mesh with the gear 201.

[0032] A hydraulic rod 211 is provided at the end of the support rod 210 away from the drive seat 200. The cylinder of the hydraulic rod 211 is fixedly connected to the support rod 210, and the piston end of the hydraulic rod 211 is fixedly connected to the cutter 220. The piston end of the hydraulic rod 211 is distributed radially along the wire harness.

[0033] When the pneumatic system drives the mounting base 120 to extend the end of the wire harness into the cutting cavity 121, the piston end of the hydraulic rod 211 drives the cutter 220 to cut radially into the insulation layer of the wire harness. After the cutter 220 cuts through the insulation layer of the wire harness, the gear 201 drives the drive base 200 to rotate, and the drive base 200 drives the cutter 220 to perform circumferential cutting on the outer surface of the wire harness through the support rod 210.

[0034] It should be noted that the rotation of gear 201 is driven by a motor, the thickness of the wire harness insulation layer is known data, and the depth to which the cutter 220 needs to cut radially is set by the PLC before cutting.

[0035] As the number of wire harnesses cut by the cutter 220 increases, the two cutters 220 will experience different degrees of wear. To prevent the wire harness ends from becoming misaligned due to different cutting forces applied by the two cutters 220 to opposite sides of the wire harness, such as the top and bottom, this application provides a unidirectional rotating limit support 240 on the outer periphery of the wire harness. The following discloses how this limit support restricts the wire harness during cutting through unidirectional rotation: like Figure 7 As shown, a rotating rod 232 is fixedly connected to one end of the actuating rod 231 away from the limiting support 240. The rotating rod 232 is perpendicular to the actuating rod 231, that is, the rotating rod 232 is the pivot of the actuating rod 231, and the rotating rod 232 extends out from the inside of the rotating bolt 230.

[0036] Furthermore, a mounting arm 235 is fixedly connected to the side of the rotating bolt 230 away from the other rotating bolt 230. A coil spring 234 is sleeved between the inner wall of the mounting arm 235 and the outer wall of the rotating rod 232. The innermost coil of the coil spring 234 is fixedly connected to the outer wall of the rotating rod 232, and the outermost coil of the coil spring 234 is fixedly connected to the inner wall of the mounting arm 235.

[0037] The centrifugal protrusion is a force-bearing block 233 fixedly connected to the actuating rod 231, and the force-bearing block 233 is distributed along the outer radial direction of the wire harness.

[0038] When the force-bearing block 233 is not pressed down by the centripetal protrusion, the limiting support 240 remains in non-compressive contact with the outer surface of the wire harness. When the cutter 220 cuts radially into the wire harness insulation layer, even if the cutting forces of the two cutters 220 on the wire harness are different, the actuating rod 231 will not rotate outward under the structural restraint of the coil spring 234. In addition, before the two cutters 220 cut radially into the wire harness, the support rod 210 is rotated by the cutters 220, so that the two cutters 220 are located at the top and bottom of the wire harness, respectively. Therefore, the wire harness is always limited between the two limiting supports 240 at the cut. This avoids the wire harness from tilting due to uneven force on both sides caused by the difference in cutting forces of the two cutters 220.

[0039] Furthermore, since the two cutters 220 are located at the top and bottom of the wire harness respectively when they cut into it, the concentric protrusion will squeeze the two force blocks 233 inward. As a result, the lever 231 will rotate inward around the axis, and the two limit supports 240 will further press the wire harness near the cut, so that the end of the wire harness remains parallel to the whole wire harness during the radial cutting process of the cutter 220.

[0040] To facilitate understanding of the above content, Figure 8 The side view shows the support rod 210 rotating with the drive seat 200. The centripetal protrusion is a paddle 212 fixedly connected to the support rod 210. The paddle 212 is distributed along the inner radial direction of the wire harness.

[0041] Please see last. Figure 9The outer periphery of the force-bearing block 233 is located on the rotation path of the lever block 212, such as Figure 9 In the shaded area, when the dial 212 rotates with the drive seat 200, the dial 212 presses the force block 233 radially along the inner side of the harness.

[0042] After the cutter 220 radially cuts through the insulation layer of the wire harness, the drive seat 200 drives the cutter 220 to rotate around the axis of the wire harness and make a circumferential cut at its end. During this process, the toggle block 212 continuously passes near the force block 233, pressing the force block 233 inward to clamp the wire harness with the two limit supports 240. When the force block 233 is pressed by the toggle block 212, it drives the actuating rod 231 to rotate around the rotating rod 232, and causes the coil spring 234 to stretch and store elastic potential energy. When the toggle block 212 leaves the vicinity of the force block 233, the coil spring 234 releases the elastic potential energy to reset the limit support 240, thereby realizing the striking of the cut end of the wire harness by the limit support 240, so that its insulation layer can be completely separated from the overall insulation layer of the wire harness.

[0043] The above settings prevent the cutter 220 from leaving "connecting bridges" when circumferentially cutting the wire harness insulation layer. This prevents the wire harness from sliding relative to each other along the x-axis within the clamp 110 due to these "connecting bridges" when the pneumatic system retracts the cutter 220 for stripping. In other words, after stripping, the exposed metal conductor end of each wire harness remains flush. Subsequent terminal crimping does not require realignment.

[0044] The working principle of the cutting device will be explained in detail below: First, the wire harnesses to be cut are placed in each clamp 110, ensuring the cutting positions of each wire harness are flush. Next, a pneumatic system pushes two mounting bases 120 closer to the wire harness, causing the cutting ends of the wire harness to extend into the cutting cavity 121. Then, the cutter 220 cuts into the insulation layer radially along the wire harness. Once the insulation layer is cut through, the drive base 200, via the support rod 210, rotates the cutter 220, circumferentially cutting off the insulation layer at the wire harness end. Finally, maintaining the position where the cutter 220 is cutting into the insulation, the pneumatic system drives the cutter 220 to retract, completing the stripping process.

[0045] When the force-bearing block 233 is not pressed down by the toggle block 212, the limiting support 240 remains in non-pressurizing contact with the outer surface of the wire harness. When the cutter 220 cuts radially into the wire harness insulation layer, the toggle lever 231 will not rotate outward under the structural restraint of the coil spring 234. Therefore, the wire harness is always limited between the two limiting supports 240 at the cut. This avoids the wire harness from tilting due to uneven force on both sides caused by the difference in cutting force between the two cutters 220.

[0046] Since the two cutters 220 are located at the top and bottom of the wire harness respectively when they cut into it, the lever 212 will press the two force blocks 233 inward. As a result, the lever 231 rotates inward around the axis, and the two limit supports 240 will further press the wire harness near the cut, so that the end of the wire harness remains parallel to the whole wire harness during the radial cutting process of the cutter 220.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
