Description

Technical Field

[0001] This invention relates to the field of explosive module loading and assembly technology, and in particular to an automatic wire winding device suitable for the assembly of lead wires for various types of propellant modules. Background Technology

[0002] In conventional rifled artillery, the copper band of the projectile moves forward along the rifling, accumulating a copper layer on the inner surface of the bore, making the rifling surface uneven. This causes the projectile to move erratically inside the barrel, resulting in unstable flight after exiting the barrel and ultimately reduced firing accuracy.

[0003] Removing copper buildup inside the barrel requires a copper-removing agent. This agent is a low-melting-point alloy composed of lead, tin, and other alloys. During firing, the copper-removing agent is heated by the propellant gases, vaporizing and forming a eutectic with the copper buildup, which adheres to the bore surface. This eutectic is easily swept away by the high-speed propellant gases or scraped off by the cartridge band of the next shot, thus removing the copper buildup. Practical experience has shown that the use of copper-removing agents in propellant significantly improves the firing accuracy of artillery.

[0004] In the existing technology, lead wire in the explosive module is usually used as a copper remover. During the assembly of the lead wire in the explosive module, there are certain requirements for the weight of the lead wire, and the diameter of the lead wire should not be too large. This may result in the lead wire that meets the weight requirements being too long to be assembled into the cartridge. Therefore, during assembly, the appropriate length of lead wire needs to be wound and then placed into the cartridge.

[0005] Current technologies typically involve manual winding of lead wire, which is labor-intensive, takes place in harsh environments, and is inefficient. Therefore, a new, more reliable, and efficient automated wire winding mechanism is needed for the assembly of explosive modules.

[0006] Therefore, how to provide a more reliable and efficient automatic wire winding mechanism for winding lead wire for explosive modules is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of the above problems, the present invention provides an automatic wire winding device for overcoming or at least partially solving the above problems.

Detailed Implementation

[0032] 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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An automatic wire winding device is provided in an embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the device may include:

[0034] Base 1, which is used to support the various components;

[0035] The wire winding mechanism 2 includes a drive motor 21, a rotating shaft 22, and a winding ring 23. The drive motor 21 is fixedly connected to the base 1, the rotating shaft 22 is rotatably connected to the base 1, and the winding ring 23 is fixedly connected to the first end of the rotating shaft 22. The drive motor 21 is connected to the rotating shaft 22 through a transmission assembly to drive the rotating shaft 22 to rotate so that the lead wire of the target length is wound onto the winding ring 23.

[0036] The unwinding mechanism 3 includes a movable collar 31, an unwinding cylinder 32, and a cam follower 34. The movable collar 31 is fitted onto the outside of the rotating shaft 22 and is connected to the rotating shaft 22 so that the movable collar 31 can move axially relative to the rotating shaft 22 but cannot move radially relative to the rotating shaft 22. The cylinder body of the unwinding cylinder 32 is fixedly connected to the base 1, and the cam follower 34 is connected to the piston rod of the unwinding cylinder 32.

[0037] The movable collar 31 is provided with a groove 33 extending circumferentially thereon, and the cam follower 34 is connected to the groove 33. The movable collar 31 is open at one end toward the winding ring 23, and the inner diameter of the movable collar 31 is not less than the outer diameter of the winding ring 23. After the lead wire on the winding ring 23 is wound, the wire unwinding cylinder 32 is used to drive the movable collar 31 to move toward the winding ring 23 so as to push out the lead wire on the winding ring 23.

[0038] The automatic wire winding device provided in this application embodiment can drive the rotating shaft 22 to rotate via the drive motor 21, thereby driving the winding ring 23 to rotate. The incoming lead wire in contact with the winding ring 23 can be wound onto the winding ring 23. Since the diameter of the lead wire and the outer diameter of the winding ring 23 are fixed, the weight of the lead wire can be calculated after a certain number of turns. After the required weight is reached, the drive motor 21 stops power output, and the lead wire is cut off. The wire unwinding cylinder 32 drives the moving collar 31 to move towards the winding ring 23, thus ejecting the wound lead wire from the winding ring 23. This device can realize quantitative winding and automatic ejection of lead wire without human intervention, greatly improving the winding efficiency and safety of the winding process.

[0039] The movable collar 31 provided in this embodiment has a groove 33, and a cam follower 34 is connected to the groove 33, so that the movable collar 31 can be limited by the cam follower mechanism during the rotation of the rotating shaft 22, and will not move along the axial direction of the rotating shaft 22. When an ejection operation is required, the unwinding cylinder 32 can provide power to the movable collar 31 along the axial direction of the rotating shaft 22 through the cam follower 34, so that the movable collar 31 reciprocates along the axial direction of the rotating shaft 22. The movable collar 31 can be connected to the rotating shaft 22 by a spline connection.

[0040] The base 1 provided in this embodiment can be used to support other components included in the device, and can also be used to connect with other devices in the explosive module loading and assembly production line. The rotating shaft 22, as the main component driving the winding ring 23 to rotate during winding, needs to ensure smooth operation during rotation. Therefore, this embodiment provides that the second end of the rotating shaft 22 is rotatably connected to the base 1 via a bearing seat 24 and bearings 25. Two bearings 25 can be provided on the bearing seat 24, and the rotating shaft 22 is connected to the bearing seat 24 via the two bearings 25, making the rotation of the rotating shaft 22 more stable.

[0041] The drive motor 21 provided in this embodiment is used to drive the rotating shaft 22 to rotate via a transmission assembly. Specifically, the transmission assembly includes a first synchronous pulley 26, a second synchronous pulley 27, and a synchronous belt 28. The first synchronous pulley 26 is connected to the output shaft of the drive motor 21, the second synchronous pulley 27 is connected to the rotating shaft 22, and the synchronous belt 28 is fitted between the first synchronous pulley 26 and the second synchronous pulley 27. The pitch circle diameter ratio of the second synchronous pulley 27 to the first synchronous pulley 26 is 0.75. Synchronous belt drives combine the advantages of belt drives, gear drives, and chain drives. Synchronous belt drives can achieve transmission over long center distances, have accurate transmission ratios, and operate without slippage; they have high transmission efficiency; they provide smooth transmission, absorb vibration, and have low noise; and they have a wide range of applications. Synchronous belt drives do not require special tensioning, have a compact structure, are easy to maintain, and can operate in harsh environments such as high temperatures and corrosion without lubrication; however, they have high installation requirements, complex manufacturing processes, and their cost is greatly affected by batch production.

[0042] In actual assembly, a spacer 29 is provided on the rotating shaft 22, and the spacer 29 is located between the second synchronous pulley 27 and the bearing seat 24.

[0043] To increase the structural strength of the rotating shaft 22 when it rotates, this application embodiment can provide a pneumatic rotary joint 210, which is connected to the base 1 via a fixed bracket 211, and the second end of the rotating shaft 22 is connected to the pneumatic rotary joint 210 via a connecting seat 212.

[0044] To facilitate the fixing of the winding ring 23 and the cam follower 34 and ensure stability after fixing, this embodiment of the application can provide that the movable collar 31 is connected to the rotating shaft 22 through a movable bushing 35. Furthermore, the cam follower 34 is connected to the piston rod of the unwinding cylinder 32 through a mounting plate 36.

[0045] To ensure that the incoming lead wire does not swing arbitrarily as the winding ring 23 rotates, this application embodiment can provide a wire clamping mechanism 4. The wire clamping mechanism 4 includes a wire clamping cylinder 41 and a wire clamping gripper 42. The wire clamping cylinder 41 is connected to the movable collar 31, and the wire clamping gripper 42 is connected to the wire clamping cylinder 41. The wire clamping cylinder 41 is used to drive the wire clamping gripper 42 to clamp and fix the incoming lead wire.

[0046] The detailed structure and usage of the device provided in the embodiments of this application are described in detail below:

[0047] The connection relationship of the components of the device is as follows: the base 1 is fixed on the table; the winding mechanism 2 passes through the base 1 and is fixed on the side plate of the base 1; the power unit is fixed on the base 1, located above the winding device, and drives the winding mechanism 2 to rotate through the synchronous belt; the unwinding mechanism 3 is fixed on the base 1 and located below the winding mechanism 2; one end of the fixed bracket 211 is fixed on the side plate of the base 1, and the other end is fixed to the end of the winding mechanism 2.

[0048] like Figure 4 As shown, the wire winding mechanism 2 includes: a rotating shaft 22, a pneumatic rotary joint 210, a connecting seat 212, a bearing seat 24, a wire winding ring 23, a fixed ring 213, a movable collar 31, a movable bushing 35, a second synchronous pulley 27, a spacer 29, a wire clamping cylinder 41, and a wire clamping gripper 42; the bearing seat 24 is fixed on the side plate of the base 1; the rotating shaft 22 is fixed on the bearing seat 24; the second synchronous pulley 27 is fixed on the rotating shaft 22 through the spacer 29; the connecting seat 212 is fixed at one end of the rotating shaft 22, and the pneumatic rotary joint 210 is fixed on the rotating shaft 22 through the connecting seat 212; the wire winding ring 23 is fixed on the other end of the rotating shaft 22 through the fixed ring 213; the movable collar 31 is fixed on the movable bushing 35 and connected to the rotating shaft 22, and can rotate and move back and forth on the rotating shaft 22; the wire clamping cylinder 41 is fixed on the movable collar 31, and the wire clamping gripper 42 is fixed on the wire clamping cylinder 41.

[0049] like Figure 4 As shown, the unwinding mechanism 3 includes: an unwinding cylinder 32, a mounting plate 36, and a cam follower 34; the unwinding cylinder 32 is fixed on the side plate; the mounting plate 36 is fixed on the push plate of the unwinding cylinder 32; the cam follower 34 is fixed on the mounting plate 36 and fitted into the groove 33 on the moving collar 31.

[0050] like Figure 4 As shown, the winding power device includes: a servo drive motor 21, a motor mounting plate 36, a first synchronous pulley 26, and a synchronous belt 28; the servo drive motor 21 is fixed to the side plate of the base 1 through the motor mounting plate 36; the first synchronous pulley 26 is mounted on the output shaft of the servo drive motor 21, and the first synchronous pulley 26 and the second synchronous pulley 27 are connected through the synchronous belt 28.

[0051] In the synchronous belt drive mechanism, the pitch circle diameter ratio of the two synchronous pulleys is 0.75. The larger diameter second synchronous pulley 27 is mounted on the rotating shaft 22, and the smaller diameter first synchronous pulley 26 is mounted on the output shaft of the servo motor.

[0052] The working process of the automatic wire winding device is described as follows:

[0053] When the device is running, the incoming lead wire is pulled onto the wire clamping gripper 42. The wire clamping cylinder 41 drives the wire clamping gripper 42 to close, clamping and fixing the incoming lead wire. The servo drive motor 21 in the winding power device drives the rotating shaft in the winding mechanism 2 to rotate through the synchronous belt pulley transmission mechanism. The lead wire is fixed by winding the wire ring 23 in the winding mechanism 2. At the same time, the wire unwinding mechanism 3 is limited by the moving collar 31 in the winding mechanism 2 when it rotates through the cam follower 34. After waiting for the required number of turns, the lead wire is cut off. The servo motor in the power device stops, the wire clamping gripper 42 releases the lead wire, and the wire unwinding cylinder 32 drives the moving collar 31 on the rotating shaft 22 to move forward through the cam follower 34 installed on it, pushing out the lead wire wound on the winding ring 23, completing the automatic wire winding process.

[0054] The air pipe of the wire clamping cylinder 41 is connected to an external air source through a hollow rotating shaft 22 and a pneumatic rotary joint 210. The pneumatic rotary joint 210 is fixed to a fixed bracket 211 to increase structural strength during rotation. When cutting lead wire, the cutting mechanism built into the explosive module loading and assembly line can be used to perform the cutting process.
