Description

Technical Field

[0001] The invention relates to the field of assembly installation of aircraft drain pipes, in particular to an automatic winding device for heating resistance wires used in aircraft drain pipes. Background Art

[0002] The aircraft drain pipe is used to discharge wastewater from the onboard waste system when the aircraft is flying, so that the discharged wastewater will not impact the tail of the fuselage, and is used to empty the waste system when the aircraft is parked on the ground. In order to prevent the aircraft drain pipe from freezing, the drain pipe is usually heated by electric heating to maintain the temperature of the drain pipe. The commonly used electric heating method is to evenly wrap the aircraft drain pipe with a resistance wire on the aircraft drain pipe by manual winding, and then heat the resistance wire by energizing it. The heated resistance wire contacts the drain pipe and heats the drain pipe by heat conduction. Since the heating of the drain pipe is achieved by heat conduction through the heating resistance wire, whether the drain pipe is heated evenly is directly related to the tightness and uniformity of the winding of the heating resistance wire on the drain pipe. Therefore, it is particularly necessary to be able to tightly and evenly wind the heating resistance wire on the drain pipe.

[0003] The traditional way to wind the resistance wire around the drain pipe is generally to use manual winding. The manual winding method generally involves fixing the drain pipe, folding a certain length of the heating resistance wire in half, fixing one side of the folded wire at the winding start position of the drain pipe, manually tightening the two ends of the other side of the heating resistance wire, and winding along the outer surface of the drain pipe. The winding direction and strength are all manually controlled. On the one hand, the heating resistance wire is not protected in the front and back directions and the up and down directions during the winding process, which can easily cause the winding resistance wire to deform and affect the winding effect; on the other hand, the heating resistance wire wound on the outer surface of the drain pipe is folded and two wires are wound at the same time. The manual winding method can easily cause the resistance wires to overlap each other during winding; on the other hand, the tension, winding speed and winding precision of the manual winding method are all handled manually, without protection function, and there are problems such as low precision, low efficiency and low safety factor. Summary of the invention

[0049] The use process of the above-mentioned rotating mechanism 1 is as follows: put the folded head 51 of the heating resistance wire 5 after folding on the starting fixing clamp 161, and then insert the folding head fixing bolt 162 into the hole of the folded head 51 of the heating resistance wire 5, so that the folded head 51 is fixed to one end of the discharge pipe 4, and then the winding servo motor 11 is used to drive the winding servo motor 11, the winding reducer 12, the winding coupling 13, the coupling 14 and the discharge pipe connecting shaft 15 to rotate in sequence, thereby driving the discharge pipe 4 to rotate, so that the heating resistance wire 5 is wound on the discharge pipe 4.

The wire-in direction roller 25 and the wire-winding direction roller 26 are used to support the heating resistor wire 5 entering the rotating mechanism 1 from the wire-arranging mechanism 2 so that the heating resistor wire 5 is substantially in the same plane as the coupling 14 and the drain pipe connecting shaft 5 .

[0051] Furthermore, the cable arrangement mechanism 2 further includes a limit assembly, which includes a left limit switch and a right limit switch. The left limit switch and the right limit switch are respectively installed on the left and right sides of the cable arrangement slide rail 22 to limit the movement range of the cable arrangement slider 23 on the cable arrangement slide rail 22.

[0052] In order to realize the function of the cable linear drive 27, please refer to Figure 1 , Figure 2 and Figure 6 In a preferred embodiment, the wire-arranging linear drive member 27 includes a wire-arranging screw rod 271, a wire-arranging nut 272 and a wire-arranging motor 273. The wire-arranging screw rod 271 is rotatably arranged on the slide rail support plate 21. The wire-arranging nut 272 is threadedly connected to the wire-arranging screw rod 271.

The wire-arranging motor 273 is connected to the wire-arranging screw rod 271 and is used to drive the wire-arranging screw rod 271 to rotate.

[0053] The use process of the above-mentioned wire arrangement mechanism 2 is as follows: the wire arrangement motor 273 drives the wire arrangement screw rod 271 to rotate, and the wire arrangement screw rod 271 acts on the wire arrangement nut 272. Since the wire arrangement nut 272 is limited by the wire arrangement slider 22 and cannot rotate, the rotation of the wire arrangement screw rod 271 is converted into the movement of the wire arrangement nut 272, thereby driving the wire arrangement slider 22 to move, and the wire arrangement slider 22 drives the vertical plate 24, the wire feeding direction roller 25, and the winding direction roller 26 to move synchronously, so that the heating resistance wire 5 moves along the length direction of the discharge pipe 4.

The straightening roller group 31, the front wire feeding roller 32, the rear wire feeding roller 33, the wire feeding roller 34, the line feeding roller 35 and the direction-changing nylon roller 36 are all rotatably arranged on the vertical plate 24. After being folded, the heating resistance wire 5 enters the tension control component 37 along the straightening roller group 31, the front wire feeding roller 32, the rear wire feeding roller 33, the wire feeding roller 34 and the line feeding roller 35 in sequence. After passing through the tension control component 37, it is wound around the winding direction roller 26 via the direction-changing nylon roller 36. In this embodiment, the straightening roller group 31, the front wire feed roller 32, the rear wire feed roller 33, the online feed roller 34, the offline feed roller 35, and the changing nylon roller 36 are all made of nylon material. Through the rolling clamping of the straightening roller group 31, the front wire feed roller 32, the rear wire feed roller 33, the online feed roller 34, the offline feed roller 35, and the changing nylon roller 36, the jitter of the heating resistance wire 5 in the transmission state is reduced, and the shape of the heating resistance wire 5 is not affected. At the same time, the directions of the straightening roller group 31, the front wire feed roller 32, the rear wire feed roller 33, the online feed roller 34, the offline feed roller 35, and the changing nylon roller 36 are different, and the heating resistance wire 5 in transmission is clamped from the up and down directions and the front and back directions, which solves the problem of deformation of the heating resistance wire 5 due to uneven force during the winding process.

[0055] To specifically implement the function of the tension control component 37, please refer to Figure 1 , Figure 2 and Figure 7-10 In a preferred embodiment, the tension control assembly 37 comprises an upper belt fixing plate 371, an upper belt left guide wheel 372, an upper belt right guide wheel 373, an upper end synchronous belt 374, a lower belt left guide wheel 375, a lower belt right guide wheel 376, a lower end resistance synchronous belt 377, a tension control assembly 378 and a clamping assembly 379. The upper belt fixing plate 371 is hinged to the vertical plate 24; the upper belt left guide wheel 372 is rotatably disposed at one end of the upper belt fixing plate 371; the upper belt right guide wheel 373 is rotatably disposed at the other end of the upper belt fixing plate 371; the upper end synchronous belt 374 is closed, one end of the upper end synchronous belt 374 is wound around the upper belt left guide wheel 372, and the other end of the upper end synchronous belt 374 is wound around the upper belt right guide wheel 373.

[0056] The lower belt left guide wheel 375 is rotatably set at one end of the vertical plate 24; the lower belt right guide wheel 376 is rotatably set at the other end of the vertical plate 24; the lower end resistance synchronous belt 377 is closed, and the lower end resistance synchronous belt 377 and the upper end synchronous belt 374 are used to clamp the heating resistance wire 5, one end of the lower end resistance synchronous belt 377 is wound around the lower belt left guide wheel 375, and the other end of the lower end resistance synchronous belt 377 is wound around the lower belt right guide wheel 376; the tension control component 378 is connected to the lower end resistance synchronous belt 377 and is used to adjust the size of the rotational resistance torque of the lower end resistance synchronous belt 377; the clamping component 379 is used to clamp the upper belt fixing plate 371 and the vertical plate 24.

[0057] To implement the function of the tension control component 378, please refer to Figure 1 , Figure 2 and Figure 7-10 In a preferred embodiment, the tension control assembly 378 includes a tension adjustment wheel 3781 and a magnetic powder brake 3782. The tension adjustment wheel 3781 is rotatably arranged on the vertical plate 24, the lower end resistance synchronous belt 377 is wound around the tension adjustment wheel 3781, and the output end of the magnetic powder brake 3782 is fixedly connected to the tension adjustment wheel 3781. The magnetic powder brake 3782 is based on the electromagnetic principle and uses magnetic powder to transmit torque. It has the characteristics that the excitation current and the transmission torque are basically linear. It can transmit a certain torque regardless of the slip, has the advantages of fast response speed, simple structure, no pollution, no noise, no impact vibration, and energy saving. It is a multi-purpose, high-performance automatic control component. Its working principle is as follows: The magnetic powder brake is a new type of transmission component that uses magnetic powder as a medium and forms a magnetic powder chain to transmit torque when powered on. It is mainly composed of an inner rotor, an outer rotor, an excitation coil and magnetic powder. When the coil is not energized, the active rotor rotates. Due to the centrifugal force, the magnetic powder is thrown onto the inner wall of the active rotor. There is no contact between the magnetic powder and the driven rotor, and the active rotor idles. After the DC power supply is turned on, an electromagnetic field is generated. The working medium magnetic powder forms a magnetic powder chain under the action of magnetic lines of force, connecting the inner rotor and the outer rotor, thereby achieving the purpose of transmitting and braking torque.

[0058] Specifically in this embodiment, the magnetic powder brake 3782 can control the size of the resistance torque encountered by the tension adjustment wheel 3781 when it rotates, thereby adjusting the size of the rotational resistance torque of the lower end resistance synchronous belt 377. The greater the rotational resistance torque of the lower end resistance synchronous belt 377, the greater the resistance encountered by the heating resistance wire 5 clamped between the lower end resistance synchronous belt 377 and the upper end synchronous belt 374, and thus the greater the tension during winding, and vice versa.

[0059] To specifically implement the function of the clamping assembly 379, please refer to Figure 1 , Figure 2 and Figure 7-10 In a preferred embodiment, the clamping assembly 379 includes a left fixed buckle 3791, a right fixed buckle 3792, a left fixed block 3793 and a right fixed block 3794. The left fixed buckle 3791 is hinged to one end of the vertical plate 24, the right fixed buckle 3792 is hinged to the other end of the vertical plate 24, the left fixed block 3793 is fixed to one end of the upper belt fixing plate 371, the left fixed block 3793 is provided with a left fixed bayonet matched with the left fixed buckle 3791, the right fixed block 3794 is fixed to the other end of the upper belt fixing plate 371, and the right fixed block 3794 is provided with a right fixed bayonet matched with the right fixed buckle 3792. In this embodiment, the left fixed buckle 3791 and the right fixed buckle 3792 are both push-pull type quick clamps.

[0060] The use process of the above-mentioned wire feeding mechanism 3 is as follows: first, loosen the left fixing buckle 3791 and the right fixing buckle 3792; then, flip the upper belt fixing plate 371 to a position perpendicular to the vertical plate 24; then, the folded heating resistance wire 5 is passed through the tension control component 37 along the lower belt left guide wheel 375, the lower end resistance synchronous belt 377 and the lower belt right guide wheel 376; then, flip the upper belt fixing plate 371 back to a position parallel to the vertical plate 24 (as shown in various views); finally, fasten the left fixing buckle 3791 to the left fixing bayonet, and fasten the right fixing buckle 3792 to the right fixing bayonet, so that the upper belt fixing plate 371 and the vertical plate 24 are fixed. At this time, the heating resistance wire 5 is between the upper end synchronous belt 374 and the lower end resistance synchronous belt 377, passes through the tension control component 37, and enters the winding starting position through the changing nylon roller 36, completing a wire feeding process.

[0061] In order to better understand the present invention, the following Figure 1-Figure 11 The working process of the automatic winding device for the aircraft drain pipe heating resistance wire provided by the present invention is described in detail:

[0062] First, loosen the left fixing buckle 3791 and the right fixing buckle 3792; then, flip the upper belt fixing plate 371 to a position perpendicular to the vertical plate 24; then, the folded heating resistance wire 5 is passed through the tension control component 37 along the lower belt left guide wheel 375, the lower end resistance synchronous belt 377 and the lower belt right guide wheel 376; then, flip the upper belt fixing plate 371 back to a position parallel to the vertical plate 24 (as shown in various views); finally, fasten the left fixing buckle 3791 to the left fixing bayonet, and fasten the right fixing buckle 3792 to the right fixing bayonet, so that the upper belt fixing plate 371 and the vertical plate 24 are fixed. At this time, the heating resistance wire 5 is between the upper end synchronous belt 374 and the lower end resistance synchronous belt 377, and enters the winding starting position after passing through the tension control component 37 through the changing nylon roller 36;

[0063] Afterwards, the folded head 51 of the heating resistance wire 5 is put on the head fixing clamp 161, and then the folding head fixing bolt 162 is inserted into the hole of the folded head 51 of the heating resistance wire 5, so that the folded head 51 is fixed to one end of the discharge pipe 4, and then the winding servo motor 11 is driven in sequence to rotate the winding servo motor 11, the winding reducer 12, the winding coupling 13, the coupling 14 and the discharge pipe connecting shaft 15, thereby driving the discharge pipe 4 to rotate, so that the heating resistance wire 5 is wound on the discharge pipe 4;

[0064] During this process, the wire arrangement motor 273 drives the wire arrangement screw rod 271 to rotate, and the wire arrangement screw rod 271 acts on the wire arrangement nut 272. Since the wire arrangement nut 272 is limited by the wire arrangement slider 22 and cannot rotate, the rotation of the wire arrangement screw rod 271 is converted into the movement of the wire arrangement nut 272, thereby driving the wire arrangement slider 22 to move. The wire arrangement slider 22 drives the vertical plate 24, the wire feed direction roller 25, and the winding direction roller 26 to move synchronously, so that the heating resistor wire 5 moves along the length direction of the drain pipe 4, thereby realizing the heating resistor wire 5 being wound around the drain pipe 4.
