Description

Technical Field

[0001] This invention relates to the field of wire stripping technology, and more particularly to a wire stripping device that adapts to wire harnesses of different specifications. Background Technology

[0002] As the name suggests, a wire stripping machine is a tool used to strip the protective layer from wires and cables. Common wire stripping machines include manual and automatic types. Manual wire stripping machines generally consist of clamps and blades. The wire or cable needs to be manually clamped in the clamps, and then the outer sheath is cut and stripped by rotation or pressure. Manual wire stripping machines are suitable for smaller wires or cables and are more flexible to operate, but they require higher operator skills. Automatic wire stripping machines, on the other hand, are automated wire stripping devices, generally equipped with multiple sets of blades, and can strip wires and cables of various specifications.

[0003] For example, patent application CN 212257979 U discloses a wire harness stripping device that facilitates adjustment of stripping length, including a base on which a stripping mechanism is mounted. One side of the stripping mechanism has a conveying guide groove for conveying the wire harness, and the other side has a limiting mechanism for limiting the stripping length of the wire harness. The limiting mechanism includes a slot formed on the base along the wire harness conveying direction, a transverse plate below the slot that can move along the length direction of the slot, a lifting rod passing through the slot and movable up and down on the transverse plate, and a baffle integrally formed at the top of the lifting rod that can abut against the end of the wire harness. However, although this device achieves wire harness stripping, it lacks an effective limiting device, resulting in inconsistent stripping lengths and difficulty in guaranteeing stripping quality. Furthermore, the layout of this stripping device is unreasonable; the lengths and diameters of the wire harnesses to be stripped vary, requiring the use of multiple devices for separate operation, which has significant limitations. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a stripping device that adapts to wire harnesses of different specifications.

[0005] The objective of this invention is achieved through the following technical solution: A wire stripping device adaptable to different specifications includes a frame, on which a clamping assembly for holding the cable is provided. A driving assembly is provided on one side of the clamping assembly. A slide plate and a support plate are slidably provided on the driving assembly. A ball spline is pivotally provided on the slide plate. The ball spline has at least a spline shaft and a spline sleeve. The spline sleeve can rotate under the action of a rotating assembly. A cutting frame is fixedly provided on the spline shaft. A pin is fixedly provided on the cutting frame. A transmission arm is pivotally provided on the pin. A cutting blade is fixedly provided at one end of the transmission arm. A connecting arm is pivotally provided at the other end. A connecting seat is fixedly provided on the spline sleeve. The other end of the connecting arm is pivotally provided on the connecting seat. The frame also includes a transfer assembly for driving the slide plate to slide and a telescopic assembly for driving the spline shaft to telescopically move. The splined shaft has a natural state and a retracted state; When the spline shaft is in its natural state, the cable can be positioned by contacting the spline shaft, and the transmission arm is in a horizontal state. When the spline shaft is in the retracted state, the retraction of the spline shaft causes the transmission arm to tilt until the distance between the cutting blades is equal to the diameter of the stripped wire harness.

[0006] Preferably, the drive assembly includes at least a drive plate fixedly mounted on the frame, a drive rod fixedly mounted between the drive plates, a sliding sleeve sleeved on the drive rod, and the slide plate and the support plate respectively fixedly mounted on the corresponding sliding sleeve.

[0007] Preferably, the drive plate is pivotally provided with a drive shaft, one end of which is fixedly connected to the motor shaft of a drive motor fixedly mounted on the frame; the drive shaft is provided with a drive nut adapted to it, and the support plate is fixedly mounted on the drive nut.

[0008] Preferably, the clamping assembly includes at least a connecting plate fixedly mounted on one of the drive plates, a connecting frame fixedly mounted on the end side of the connecting plate, a clamping cylinder fixedly mounted on the connecting frame, and a clamping head fixedly mounted on the cylinder shaft of the clamping cylinder.

[0009] Preferably, a sensing plate is fixedly mounted on the support plate, a sensor is provided on the frame, a sensing slot is provided on the sensor, and the sensing plate can be placed inside the sensor.

[0010] Preferably, the rotating assembly includes at least a servo motor fixedly mounted on the slide plate, a drive wheel fixedly mounted on the motor shaft of the servo motor, a driven wheel fixedly mounted on the spline sleeve, and a transmission belt wound between the drive wheel and the driven wheel.

[0011] Preferably, the telescopic assembly includes at least an electric cylinder fixedly mounted on the support plate, wherein the cylinder shaft of the electric cylinder is fixedly connected to the spline shaft.

[0012] Preferably, the transfer assembly includes at least a transfer shaft pivotally mounted on the support plate, one end of the transfer shaft being fixedly connected to the motor shaft of a transfer motor fixedly mounted on the support plate, and a transfer nut being provided on the transfer shaft via a lead screw drive, with the sliding plate fixedly mounted on the transfer nut.

[0013] Preferably, the cutting frame has a threaded hole, and a locking bolt passes through the threaded hole to lock the cutting frame onto the splined shaft.

[0014] The beneficial effects of this invention are mainly reflected in: 1. The device is ingeniously designed with a compact structure and reasonable layout, achieving a high degree of integration, reducing space occupation, and is applicable to various specifications of wire harnesses. At the same time, it can precisely limit the stripping length of the wire harness, greatly improving the yield and accuracy, and has a wide range of applicability.

[0015] 2. The drive shaft and drive nut cooperate to drive the slide plate and support plate to move synchronously, thereby realizing the position adjustment of wire harnesses of different lengths. This adjustment method is simple and stable. In addition, it is preferred to use a screw drive for driving, which can efficiently and accurately convert rotary motion into linear motion. It is suitable for high-precision and high-load transfer applications and greatly improves accuracy.

[0016] 3. When the splined shaft is in its natural state, it abuts against the wire harness for positioning, ensuring a uniform stripping position and significantly improving yield. When the splined shaft retracts, it drives the cutting frame backward via a pin, causing the drive arm to rotate around the pin. The cutting blades then work together to clamp the wire harness. This compact structure achieves high integration, reducing space requirements. Furthermore, driven by only one electric cylinder, it significantly reduces costs and facilitates business development.

[0017] 4. The drive wheel, driven wheel, and transmission belt work together to drive the spline sleeve to rotate, thereby enabling the cutting blade to cut the wire harness. The operation is simple, convenient, stable, and reliable. At the same time, it is easy to disassemble, replace, and maintain, greatly improving work efficiency.

[0018] 5. The sliding plate is driven to move by the cooperation of the transfer shaft and the transfer nut, thereby stripping the cable. This operation is fully automated and requires no manual operation, which greatly improves work efficiency. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3As shown, the present invention discloses an adaptive stripping device for wire harnesses of different specifications, including a frame 1, on which a clamping assembly 2 for clamping the cable is provided. The clamping assembly 2 includes at least a connecting plate 21, a connecting frame 22 fixedly provided on the end side of the connecting plate 21, a clamping cylinder 23 fixedly provided on the connecting frame 22, and a clamping head 24 fixedly provided on the cylinder shaft of the clamping cylinder 23.

[0025] A drive assembly 3 is provided on one side of the clamping assembly 2. The drive assembly 3 includes at least a drive plate 31 fixedly mounted on the frame 1. A drive rod 32 is fixedly mounted between the drive plates 31. A sliding sleeve 33 is fitted on the drive rod 32. The slide plate 4 and the support plate 6 are respectively fixedly mounted on the corresponding sliding sleeves 33. Further, a drive shaft 34 is pivotally mounted on the drive plate 31. One end of the drive shaft 34 is fixedly connected to the motor shaft of the drive motor 35 fixedly mounted on the frame 1. A drive nut 36 adapted to the drive shaft 34 is provided, and the support plate 6 is fixedly mounted on the drive nut 36. In the above, the drive shaft 34 and the drive nut 36 cooperate to drive the slide plate 4 and the support plate 6 to move synchronously, thereby realizing the position adjustment of wire harnesses of different lengths. This adjustment method is simple and stable. In addition, it is preferable to use a screw drive for driving, which can efficiently and accurately convert rotary motion into linear motion, suitable for high-precision and high-load transfer applications, and greatly improving accuracy. In addition, a sensing plate 61 is fixedly installed on the support plate 6, and a sensor 62 is installed on the frame 1. The sensor 62 has a sensing groove, and the sensing plate 61 can be placed inside the sensor 62. The sensing plate 61 and the sensor 62 work together to monitor the position of the support plate 6 in real time, so as to ensure the accuracy of the movement position to the greatest extent.

[0026] In this application, a ball spline 5 is pivotally mounted on the slide plate 4. The structure of the ball spline 5 is prior art and not a key point of protection in this invention; therefore, its structure will not be described in detail. As described above, the ball spline 5 has at least a spline shaft 51 and a spline sleeve 52. A cutting frame 53 is fixedly mounted on the spline shaft 51, and a pin 55 is fixedly mounted on the cutting frame 53. A transmission arm 57 is pivotally mounted on the pin 55. A cutting blade 58 is fixedly mounted at one end of the transmission arm 57, and a connecting arm 59 is pivotally mounted at the other end. A connecting seat 50 is fixedly mounted on the spline sleeve 52, and the other end of the connecting arm 59 is pivotally mounted on the connecting seat 50. This design is ingenious. When the spline shaft 51 is in its natural state, it abuts against the wire harness for positioning, thereby ensuring a uniform position for stripping the wire harness and greatly improving the yield rate. When the spline shaft 51 retracts, it drives the cutting frame 53 to move backward via the pin 55, causing the transmission arm 57 to rotate around the pin 55. The cutting blades 58 then cooperate to clamp the wire harness. This structure is compact, highly integrated, and occupies less space. Furthermore, it is driven by only one electric cylinder, greatly reducing costs and facilitating business development.

[0027] Furthermore, the spline shaft 51 is driven to extend and retract by a telescopic cylinder 8. Specifically, the telescopic assembly 8 includes at least an electric cylinder 81 fixedly mounted on the support plate 6, with the cylinder shaft of the electric cylinder 81 fixedly connected to the spline shaft 51. The preferred use of an electric cylinder 81 is due to its high control precision. Of course, lead screw drives and other methods can also be used, all of which fall within the scope of protection of this invention.

[0028] In this invention, the spline sleeve 52 can rotate under the action of the rotating assembly 9. The rotating assembly 9 includes at least a servo motor 91 fixedly mounted on the slide plate 4. A drive wheel 92 is fixedly mounted on the motor shaft of the servo motor 91, and a driven wheel 93 is fixedly mounted on the spline sleeve 52. A transmission belt 94 is wound between the drive wheel 92 and the driven wheel 93. As described above, the drive wheel 92, the driven wheel 93, and the transmission belt 94 cooperate to drive the spline sleeve 52 to rotate, thereby enabling the cutting blade 58 to cut the wire harness. Furthermore, in this invention, the rotational speed of the servo motor 91 can be controlled by a PLC control system. The above operation method is simple, convenient, stable, and reliable. It also facilitates disassembly, replacement, and maintenance, greatly improving work efficiency.

[0029] Preferably, the cutting frame 53 has a threaded hole 531, and a locking bolt 532 passes through the threaded hole 531 to lock the cutting frame 53 onto the spline shaft 51. The connection by the locking bolt can greatly improve work efficiency.

[0030] The frame 1 is also equipped with a transfer assembly 7 for driving the slide plate 4 to slide. The transfer assembly 7 includes at least a transfer shaft 71 pivotally mounted on the support plate 6. One end of the transfer shaft 71 is fixedly connected to the motor shaft of the transfer motor 72 fixedly mounted on the support plate 6. A transfer nut 73, driven by a lead screw, is provided on the transfer shaft 71. The slide plate 4 is fixedly mounted on the transfer nut 73. The transfer shaft 71 and the transfer nut 73 work together to drive the slide plate 4 to move, thereby stripping the cable. This operation is fully automated and requires no manual operation, greatly improving work efficiency. In addition, the lead screw drive can efficiently and accurately convert rotary motion into linear motion, which is suitable for high-precision and high-load transfer applications, greatly improving accuracy.

[0031] The working process of this invention is briefly described below: The wire harness is conveyed horizontally until the end of the wire harness abuts against the spline shaft 51. At this time, the electric cylinder 81 controls the spline shaft 51 to retract. The spline shaft 51 drives the cutting frame 53 to move backward through the pin 55, thereby causing the transmission arm 57 to rotate around the pin 55. The cutting blades 58 cooperate to clamp the wire harness.

[0032] After clamping is completed, the servo motor 91 starts and drives the spline sleeve 52 to rotate through the cooperation of the drive wheel 92, the transmission belt 94 and the driven wheel 93, so that the cutting blade 58 cuts the wire harness. After cutting is completed, the transfer motor 72 starts and drives the slide plate 4 to move through the cooperation of the transfer shaft 71 and the transfer nut 73, so as to strip the cable.

[0033] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0034] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
