Aerospace light cable take-up device

Abstract

This invention discloses a lightweight cable winding device for aerospace applications, relating to the technical field of cable winding devices. It includes a base plate, a vertical plate, a winding shaft, a sliding seat, a reciprocating translation unit, and a telescopic unit. A mounting base is fixed to the telescopic unit, and a guide block is horizontally slidably connected to the mounting base. The upper surface of the guide block has a recessed guide groove. The guide block is driven to reciprocate horizontally by an actuating unit located on the mounting base. This invention drives the sliding seat to reciprocate horizontally via the reciprocating translation unit. The cable is engaged in the guide groove of the guide block. As the sliding seat reciprocates horizontally, the cable can reciprocate along the axial direction of the winding shaft during winding, resulting in the cable being evenly wound onto the shaft. Furthermore, due to the telescopic unit, the guide block can move up and down, allowing the cable to move downwards as the winding thickness increases, reducing resistance during cable winding.

Technical Field

[0001] This invention relates to the field of cable winding device technology, specifically a lightweight cable winding device for aerospace applications. Background Technology

[0002] When storing or installing aerospace cables, winding equipment is required to wind the cables. Existing winding equipment mainly uses a motor to drive the winding shaft to rotate, thereby winding the cable. However, when winding cables, the current winding equipment is prone to uneven winding thickness, which can easily lead to scattering.

[0003] Therefore, we propose a lightweight cable winding device for aerospace applications. Summary of the Invention

[0004] The purpose of this invention is to provide a lightweight cable winding device for aerospace applications to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A lightweight cable winding device for aerospace applications, comprising: A base plate and vertical plates fixed to both sides of the base plate, with a winding shaft horizontally rotatably connected to the two vertical plates; A sliding seat is horizontally slidably connected to the base plate. The sliding seat is driven to move horizontally reciprocally by a reciprocating translation unit provided on the base plate. The sliding seat is provided with a telescopic unit. A mounting base is fixed to the telescopic unit, and a guide block is slidably connected to the mounting base. The upper surface of the guide block is provided with a recessed guide groove. The guide block is driven to move horizontally back and forth by a toggle unit provided on the mounting base.

[0006] Furthermore, the take-up shaft is driven to rotate by a take-up motor mounted on one of the vertical plates.

[0007] Furthermore, the reciprocating translation unit includes: Fixed plates are fixed to both sides of the base plate; A lead screw is horizontally rotatably connected to two fixed plates at both ends, and the lead screw is driven to rotate by a servo motor mounted on one of the fixed plates; A nut is fitted onto the sliding seat, and the nut is threaded onto the lead screw.

[0008] Furthermore, two guide posts are horizontally fixed to the two fixed plates, and the sliding seat has through holes for the guide posts to pass through freely.

[0009] Furthermore, the telescopic unit includes: A fixing sleeve vertically fixed to the sliding seat; A telescopic column is inserted into the fixed sleeve, and the upper end of the telescopic column extends out of the fixed sleeve and is fixedly connected to the mounting base; A first elastic reset component is provided inside the fixed sleeve, which is used to drive the telescopic column to move upward.

[0010] Further, the first elastic reset component includes: A first spring is vertically installed inside the fixed sleeve. The first spring elastically abuts against the telescopic column and drives the telescopic column to move upward. A first limiting pin is fixed to the lower end of the telescopic column. The fixing sleeve has a first waist-shaped hole for the first limiting pin to be inserted. The first limiting pin can slide freely up and down in the first waist-shaped hole.

[0011] Furthermore, a limiting rod is horizontally fixed to the mounting base, and a sliding block is slidably fitted onto the limiting rod. The lower surface of the guide block is fixed to the upper surface of the sliding block.

[0012] Furthermore, a second spring is wound around the limiting rod, and the two ends of the second spring elastically abut against the sliding block and the inner wall of the mounting base, respectively.

[0013] Furthermore, the toggle unit includes: The column is vertically fixed to the fixed plate. A lifting rod is horizontally sleeved on both columns. The lifting rod has a sliding hole for the column to pass through freely. The lifting rod has a notch. The mounting base has a clearance groove for the lifting rod to pass through freely. A mounting sleeve is vertically fixed to the lower surface of the sliding block. A floating rod is telescopically inserted into the mounting sleeve. The lower end of the floating rod is provided with a ball head, which is used in conjunction with the notch. A second elastic reset component is provided inside the mounting sleeve. The second elastic reset component is used to drive the floating rod to move downward, so that the ball head abuts against the inner wall of the notch.

[0014] Furthermore, the second spring return assembly includes: A third spring is vertically installed inside the mounting sleeve, the third spring elastically abutting against the floating rod and driving the floating rod to move downward; A second limiting pin is fixed to the lower end of the floating rod, and the mounting sleeve has a second oblong hole for the second limiting pin to pass freely.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention drives the sliding seat to move horizontally back and forth via a reciprocating translation unit. The cable is inserted into the guide groove of the guide block. As the sliding seat moves horizontally back and forth, the cable can move back and forth along the axial direction of the winding shaft when the winding shaft is winding, thereby making the cable evenly wound on the winding shaft. In addition, due to the setting of the telescopic unit, the guide block can move up and down, so that as the winding thickness of the cable increases, the cable can drive the guide block to move downward, reducing the resistance during cable winding. The present invention provides a toggle unit so that when the cable is being wound up, the guide block will be driven by the toggle unit to move horizontally back and forth, that is, the cable can swing back and forth, so that the cable will not stack when it is wound on the winding shaft. This invention allows the ball head to alternately slide on the inner wall of multiple notches when the sliding seat moves horizontally back and forth, and with the elastic support of the floating rod by the third spring, the sliding block can produce a small horizontal back and forth movement when the sliding seat moves horizontally, thereby allowing the cable to swing and making it less likely for the cable to stack during the winding process.

[0018] The technical solutions of 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.

[0019] Please see Figures 1-5 The present invention provides a technical solution: a lightweight cable winding device for aerospace applications, comprising a base plate 3 and vertical plates 4 fixedly connected to both sides of the base plate 3. A winding shaft 7 is horizontally rotatably connected to the two vertical plates 4 by ball bearings. The winding shaft 7 is driven to rotate by a winding motor 5 installed on one of the vertical plates 4. A fixing plate 1 is welded to each of the opposite sides of the base plate 3. A bearing is embedded in the fixing plate 1. A lead screw 15 is passed through the two bearings. The lead screw 15 is driven to rotate by a servo motor 10 installed on one of the fixing plates 1. A threaded nut sleeve 13 is threaded onto the lead screw 15. A sliding seat 12 is fixedly sleeved on the threaded nut sleeve 13. A lug is fixedly connected to each side of the sliding seat 12. A guide post 14 is horizontally fixed to both fixing plates 1. A through hole is provided on the lug for the guide post 14 to pass freely. A fixed sleeve 11 is vertically fixed to the top of the sliding seat 12. A telescopic column 26 is telescopically inserted into the fixed sleeve 11. A first spring 28 is vertically installed inside the fixed sleeve 11. The first spring 28 elastically abuts against the telescopic column 26 and drives the telescopic column 26 to move upward. A first limiting pin 27 is fixedly connected to the lower end of the telescopic column 26. The fixed sleeve 11 has a first oblong hole 29 for the first limiting pin 27 to be inserted. The first limiting pin 27 slides freely up and down in the first oblong hole 29. The upper end of the telescopic column 26 protrudes from the fixed sleeve. 11 and a mounting base 8 is fixedly connected. The mounting base 8 is U-shaped and its two vertical sections are horizontally fixedly connected to a limiting rod 25. A sliding block 18 is slidably sleeved on the limiting rod 25. The sliding block 18 slides freely horizontally on the limiting rod 25. In addition, a second spring 24 is wound around the limiting rod 25. The two ends of the second spring 24 elastically abut against the sliding block 18 and the inner side wall of the mounting base 8 respectively in the direction of the elastic force. A guide block 17 is fixedly connected to the top of the sliding block 18. A recessed guide groove 16 is opened on the upper surface of the guide block 17. A column 2 is vertically fixedly connected to the fixed plate 1. A lifting rod 6 is horizontally sleeved on both columns 2. The lifting rod 6 has a sliding hole for the column 2 to pass through freely. The lifting rod 6 has a notch 9. The mounting base 8 has a clearance groove for the lifting rod 6 to pass through freely. A mounting sleeve 23 is vertically fixedly connected to the lower surface of the sliding block 18. A floating rod 22 is telescopically inserted on the mounting sleeve 23. The lower end of the floating rod 22 has a ball head 21. The ball head 21 is used in conjunction with the notch 9. A third spring 19 is vertically installed inside the mounting sleeve 23. The third spring 19 elastically abuts against the floating rod 22 and drives the floating rod 22 to move downward. A second limiting pin 20 is fixedly connected to the lower end of the floating rod 22. The mounting sleeve 23 has a second oblong hole for the second limiting pin 20 to pass through freely.

[0020] The working principle of the present invention is as follows: When the cable is inserted into the guide groove 16 of the guide block 17, the first spring 28 elastically pushes against the telescopic column 26, causing the telescopic column 26 to move upward and the inner wall of the guide groove 16 to pull the cable upward, thereby making the cable straight. Start the winding motor 5, which drives the winding shaft 7 to rotate. When the winding shaft 7 rotates, it will pull the cable and then wind the cable. When the cable is wound, the servo motor 10 is started simultaneously. The servo motor 10 drives the lead screw 15 to rotate. When the lead screw 15 rotates, the lead screw sleeve 13 will be screwed into the lead screw 15, which will drive the sliding seat 12 to move horizontally back and forth, so that the cable can move back and forth along the axial direction of the winding shaft 7, so that the cable can be wound evenly on the winding shaft 7. As the winding thickness increases, the cable can press the guide block 17 downward, causing the guide block 17 to move downward, which in turn causes the telescopic column 26 to move downward and compress the first spring 28. The first spring 28 is in a compressed state and accumulates elastic potential energy. At the same time, because the first limiting pin 27 slides in the first waist-shaped hole 29, the telescopic column 26 will not come out of the fixed sleeve 11. Since the lifting rod 6 is sleeved on the column 2, it can only move up and down and not horizontally. As a result, when the guide block 17 moves up and down, it synchronously drives the lifting rod 6 to move up and down. When the mounting base 8 moves horizontally, the ball head 21 slides from the inner wall of one notch 9 to the top surface of the lifting rod 6, causing the floating rod 22 to compress the third spring 19. The third spring 19 accumulates elastic potential energy. At this time, the sliding block 18 moves towards the mounting base 8 and compresses the second spring 24. Then, the ball head 21 slides from the top surface of the lifting rod 6 to another notch 9. The second spring 24 changes from a compressed state to an extended state, causing the sliding block 18 to move quickly in the opposite direction. This allows the guide block 17 to move horizontally in a small amplitude, which in turn allows the guide block 17 to move the cable, causing the cable to swing slightly. This prevents the cable from stacking when it is wound on the winding shaft 7, i.e., it prevents the phenomenon of large local winding thickness. As a result, the winding thickness of the cable is more uniform at all points on the winding shaft 7 after winding.
