Abstract
Description
Technical Field
[0001] This application relates to the field of wire harness processing technology, specifically to an end stripping device for automotive wire harnesses. Background Technology
[0002] Wire harnesses are wiring components that connect various electrical devices in a circuit. They include wire cores, shielding layers, and insulation layers. During the processing of wire harnesses, in order to facilitate connection with various connectors, it is usually necessary to strip the wire harness ends to expose the internal conductive parts for connection and installation. Using automatic wire harness stripping devices is a conventional method in existing technology.
[0003] Existing stripping devices use stripping blades positioned above and below to press against each other to cut the protective sheath of the wire harness. Although the stripping blades have arc-shaped notches that match the wire harness, these notches cannot be adapted to wire harnesses of different diameters. This results in the protective sheath not being completely cut off, causing the sides of the protective sheath to easily stick to the wire harness after cutting, which affects the subsequent removal of the protective sheath.
[0004] Therefore, it is necessary to provide an automotive wiring harness end stripping device to solve the above problems.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an automotive wiring harness end stripping device that achieves the effect of adapting to the cutting operation of wiring harnesses of different diameters.
[0007] The technical solution adopted by this application to solve its technical problem is: an automotive wiring harness end stripping device, including a body, a working head, and a stripping mechanism; the working head is slidably disposed at the front end of the body, and the stripping mechanism is rotatably disposed at the end face of the working head;
[0008] The peeling mechanism includes a base plate, an adjustment component, and a cutting component. A through hole is formed in the center of the base plate. The adjustment component is movably mounted on the base plate. Multiple cutting components are provided, and each is fixed to the adjustment component circumferentially around the through hole. The adjustment component is used to control the synchronous movement of the cutting component within the slot. Thus, the wire harness enters the through hole and is placed concentrically with the through hole. The distance between the cutting component and the center of the through hole is controlled by the adjustment component to accommodate the cutting of shielding and insulation layers of wire harnesses with different diameters.
[0009] Furthermore, a support ring is fixedly installed at the end of the substrate away from the body, and a ring frame is fixedly installed on the substrate at the center of the support ring. Multiple sets of opening slots are opened at corresponding positions along the circumferential direction on the top of the support ring and the ring frame. The length direction of the multiple sets of opening slots is arranged along the radial direction of the substrate. An arc-shaped groove is opened at the end of the substrate where the opening slot is away from the center.
[0010] An electrically controlled push rod is fixedly installed at the other end of the substrate. A connecting plate is hinged to the output end of the electrically controlled push rod. The other end of the connecting plate passes through an arc groove and is hinged to the adjustment assembly. Thus, the electrically controlled push rod provides power to the adjustment assembly, and the arc groove is used to limit the movement direction of the connecting plate, so that the connecting plate moves along the arc direction of the arc groove.
[0011] Furthermore, the adjustment assembly includes an internal gear ring, multiple sets of gears, and multiple rack plates; the internal gear ring bearing is installed inside the support ring, the multiple sets of gears are mounted on the base plate through bearings and arranged in the circumferential direction, and all gears mesh with the internal gear ring; the rack plates are slidably disposed in the opening slots in a one-to-one correspondence.
[0012] The rack plate corresponds to the gear, and the rack plate has a toothed shape along its length, which meshes with the gear.
[0013] Furthermore, each rack plate corresponds to a cutting component, and the rack plate and the cutting component are detachably installed.
[0014] Furthermore, the substrate has a toothed disc structure; the height of the support ring and ring frame is higher than the height of the internal gear ring and lower than the height of the gear, and the support ring and ring frame ensure that the rack plate and the internal gear ring do not interfere with each other's operation.
[0015] Furthermore, a ring is fixedly installed on one side of the internal gear ring, a limiting groove is opened on one side of the support ring, one end of the ring passes through the limiting groove, and the inner wall is connected to the connecting plate by bolts; the side of the connecting plate and the ring hinged end is slidably connected to the arc groove.
[0016] Furthermore, the electrically controlled push rod adopts a dual Hall effect push rod. Thus, the dual Hall effect push rod can determine the push rod stroke by receiving resistance values. The change in the push rod stroke is proportional to the change in the diameter of the rack plate, thereby enabling precise control of the position of the cutting part.
[0017] Furthermore, the inner wall of the working head is provided with an annular groove and a placement groove, with the placement groove located on one side of the annular groove; the substrate is rotatably disposed within the annular groove, and a pneumatically controlled slide is fixedly installed within the placement groove, with the pneumatically controlled slide located below the substrate; a rack plate two is fixedly installed at the top of the movable part of the pneumatically controlled slide, and the end of the rack plate two away from the pneumatically controlled slide has a toothed shape along its length, which meshes with the substrate; thereby, the pneumatically controlled slide controls the rack plate two to move left and right, driving the substrate to rotate, thus providing power for the rotation of the substrate, facilitating the substrate to drive the cutting component to rotate and cut the wire harness.
[0018] Furthermore, an electrically controlled telescopic rod is provided at the front end of the machine body. The end of the electrically controlled telescopic rod away from the machine body is fixedly connected to the working head. A slide rail is fixedly installed at the front end of the machine body. The bottom of the working head is slidably connected to the slide rail. Thus, after the working head cuts the wire harness, the control component drives the cutting piece to retract slightly without leaving the insulation layer but away from the wire core. Then, the electrically controlled telescopic rod drives the working head to retract, causing the cutting piece to detach the cut insulation layer from the wire core.
[0019] The beneficial effects of this application are: the automotive wiring harness end stripping device provided by this application, by providing an adjustment component, allows the wiring harness to enter the through hole and be placed concentrically with the through hole; the distance between the cutting component and the center of the through hole is controlled by the adjustment component to cope with the cutting of shielding and insulation layers of wiring harnesses of different diameters.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0032] like Figures 1-6 As shown, this application provides an automotive wiring harness end stripping device for stripping the wire harness during wiring harness processing. In actual operation, the device is installed on one side of the conveyor line.
[0033] like Figure 1 , Figure 2 As shown, it includes a machine body 1, a working head 2, and a peeling mechanism 3; the working head 2 is slidably disposed at the front end of the machine body 1, and the peeling mechanism 3 is rotatably disposed at the end face of the working head 2;
[0034] The peeling mechanism 3 includes a base plate 31, an adjustment component 32, and a cutting component 34; the structural relationship between the working head 2 and the peeling mechanism 3 is as follows:
[0035] Reference Figure 2-Figure 3The substrate 31 has a toothed disc structure and a through hole is provided in the center of the substrate 31. A support ring 312 is fixedly installed at the end of the substrate 31 away from the body 1. A ring frame 313 is fixedly installed on the substrate 31 at the center of the support ring 312. Multiple sets of opening slots 314 are provided at corresponding positions along the circumferential direction on the top of the support ring 312 and the ring frame 313. The length direction of the multiple sets of opening slots 314 is arranged along the radial direction of the substrate 31.
[0036] Meanwhile, a cutting element 34 is slidably disposed on the end face of the substrate 31. Multiple cutting elements 34 are disposed and arranged in a circumferential direction with the through hole as the center, so that the cutting element 34 is used to cut the insulation layer of the wire harness.
[0037] In order to control the movement of the cutting component 34, an adjustment component 32 is movably disposed on the substrate 31 and fixed on the adjustment component 32; the adjustment component 32 is suitable for controlling the synchronous movement of the cutting component 34 in the opening slot 314; thereby, the wire harness enters the through hole and is placed concentrically with the through hole; the distance between the cutting component 34 and the center of the through hole is controlled by the adjustment component 32 to cope with the cutting of shielding and insulation layers of wire harnesses of different diameters.
[0038] Reference Figures 2-6 The adjusting assembly 32 includes an internal gear ring 321, multiple sets of gears 322, and multiple rack plates 323. The internal gear ring 321 is mounted in a support ring 312 with bearings. The multiple sets of gears 322 are mounted on a base plate 31 via bearings and arranged in a circumferential direction. All sets of gears 322 mesh with the internal gear ring 321. The height of the support ring 312 and the ring frame 313 is higher than the height of the internal gear ring 321 and lower than the height of the gears 322. Thus, when the internal gear ring 321 rotates, the multiple sets of gears 322 can rotate synchronously.
[0039] The rack plates 323 are slidably disposed in the opening slots 314 in a one-to-one correspondence; the rack plates 323 correspond one-to-one with the gears 322, and the rack plates 323 are provided with teeth along the length direction, which mesh with the gears 322; the thickness of the inner gear ring 321 is less than the distance between the opening slots 314 and the base plate 31; thus, while the gears 322 rotate, the rack plates 323 can be driven to slide in the opening slots 314, and the support rings 312 and the ring frame 313 ensure that the rack plates 323 and the inner gear ring 321 do not affect each other's operation.
[0040] In this application, the rack plate 323 corresponds one-to-one with the cutting element 34 and is fixedly installed with the cutting element 34. Thus, when the rack plate 323 moves, it can drive the cutting element 34 to move synchronously, thereby changing the diameter formed by the cutting elements 34 to adapt to wire harnesses of different diameters.
[0041] In addition, refer to 3- Figure 6The substrate 31 has an arc-shaped groove 311 at the end of the opening groove 314 away from the center; a ring fastener (such as...) is fixedly installed on one side of the internal gear ring 321. Figure 4 A limiting groove 3121 is provided on one side of the support ring 312, and one end of the ring buckle extends through the limiting groove 3121; an electric control push rod 33 is fixedly installed on the other end of the base plate 31, and a connecting plate 331 is hinged to the output end of the electric control push rod 33; the inner wall of the ring buckle is connected to the connecting plate 331 by bolting; the side of the connecting plate 331 and the ring buckle hinged end is slidably connected to the arc groove 311; thus, the electric control push rod 33 provides power to the adjustment component 32, and the arc groove 311 is used to limit the movement direction of the connecting plate 331, so that the connecting plate 331 moves along the arc direction of the arc groove 311.
[0042] Among them, the electric control push rod 33 adopts a dual Hall push rod. Thus, the dual Hall push rod can determine the push rod stroke by receiving the resistance value. The change of its push rod stroke is proportional to the change of the diameter of the rack plate, thereby accurately controlling the position of the cutting part 34.
[0043] Reference Figure 5 , Figure 6 The inner wall of the working head 2 is provided with an annular groove 21 and a placement groove 22, with the placement groove 22 located on one side of the annular groove 21. The substrate 31 is rotatably disposed in the annular groove 21, and a pneumatically controlled slide 41 is fixedly installed in the placement groove 22, with the pneumatically controlled slide 41 located below the substrate 31. A rack plate 2 42 is fixedly installed at the top of the movable part of the pneumatically controlled slide 41, and the end of the rack plate 2 42 away from the pneumatically controlled slide 41 is provided with a toothed shape along its length, which meshes with the substrate 31. Thus, when the adjusting component 32 cuts the cutting piece 34 into the wire harness, the pneumatically controlled slide 41 controls the rack plate 2 42 to move from one side to the other, driving the substrate 31 to rotate, thereby providing power for the rotation of the substrate 31, which facilitates the substrate 31 to drive the cutting piece 34 to rotate and perform complete cutting around the wire harness.
[0044] In order to peel off the cut insulation layer, an electrically controlled telescopic rod 11 is provided at the front end of the machine body 1. The end of the electrically controlled telescopic rod 11 away from the machine body 1 is fixedly connected to the working head 2. A slide rail 12 is fixedly installed at the front end of the machine body 1. The bottom of the working head 2 is slidably connected to the slide rail 12. Thus, after the working head 2 cuts the wire harness, the adjusting component 32 drives the cutting piece 34 to retract slightly without leaving the insulation layer but away from the wire core. Then, the electrically controlled telescopic rod 11 drives the working head 2 to retract, so that the cutting piece 34 drives the cut insulation layer to detach from the wire core.
[0045] In summary, the electrically controlled telescopic rod 11 pushes the working head 2 forward, allowing the wire harness to enter the through hole in the center of the substrate 31. The adjusting assembly 32 adjusts the position of the cutting piece 34 according to the diameter of the wire harness. The steps are as follows:
[0046] The electric actuator 33 is activated, which drives the internal gear ring 321 to rotate via the connecting plate 331. The internal gear ring 321 controls the rack plate 323 to move synchronously on the opening slot 314 via the gear 322, thereby controlling the sliding of the cutting piece 34 on the substrate 31. This allows multiple cutting pieces 34 to simultaneously move inward or outward, so as to cut wire harnesses of different diameters according to the wire harness diameter requirements. The cutting head of the cutting piece 34 adopts a sickle-type structure (e.g., ...). Figure 2 ).
[0047] For wire harnesses with excessively large diameters, the cutting element 34 cannot completely cut through the insulation layer after it enters the wire harness. After the cutting element 34 enters the insulation layer, the pneumatic slide 41 controls the rack plate 42 to move from one side to the other, thereby driving the substrate 31 to rotate and providing power for the rotation of the substrate 31. This facilitates the substrate 31 to drive the cutting element 34 to rotate and perform a complete cut around the wire harness.
[0048] Subsequently, in order to peel off the cut insulation layer, the adjusting component 32 drives the cutting piece 34 to retract slightly without leaving the insulation layer but away from the wire core, and then the electrically controlled telescopic rod 11 drives the working head 2 to retract, so that the cutting piece 34 drives the cut insulation layer to detach from the wire core.
[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
