Specifically, referring to fig. 1 and 2 together, the first rotating shaft 200 is a substantially cylindrical shaft that can be clamped or otherwise fixed by a winding machine. In some embodiments, the first rotating shaft 200 may be inserted into a fixing portion of the winding machine in an insertion manner and fixed relative to the fixing portion. In some embodiments, a clamp may also be used to fix the first rotation shaft 200.

In some embodiments, referring to fig. 1, a positioning installation surface 210 may be formed on an outer wall of the first rotating shaft 200, and the positioning installation surface 210 is a plane and is used for limiting the first rotating shaft 200 when the first rotating shaft 200 is fixed, so as to prevent the first rotating shaft 200 and a fixing portion for fixing the first rotating shaft 200 from rotating relatively. In some embodiments, the number of the positioning installation surfaces 210 may be one or more, each positioning installation surface 210 may be arranged in parallel with the axial direction of the first rotation shaft 200, and when the number of the positioning installation surfaces 210 is plural, the plurality of positioning installation surfaces 210 may be uniformly arranged around the axis of the first rotation shaft 200.

Referring to fig. 1 and 3, the second rotating shaft 300 is configured to be coaxially detachably connected to the first rotating shaft 200, the second rotating shaft 300 includes an inner shaft 310 and a bushing 320, wherein the inner shaft 310 and the bushing 320 form a slidable assembly structure therebetween, and an outer diameter of the inner shaft 310 is smaller than an outer diameter of the first rotating shaft 200 and smaller than an aperture of the receiving hole 220. In some embodiments, the inner shaft 310 may be a solid shaft or a hollow shaft, in this embodiment, the inner shaft 310 is a hollow shaft, a through hole 315 is formed in the inner shaft 310 along the axial direction, and the through hole 315 penetrates through an end surface of the inner shaft 310.

An end of the inner shaft 310 facing the first rotating shaft 200 is formed with a mounting portion 313 to which a motor carrier is mounted, and the mounting portion 313 is used to mount the motor carrier. In some embodiments, the mounting portion 313 includes an annular groove 314 opened in the inner shaft 310, the annular groove 314 is formed on the outer surface of the inner shaft 310 and is formed along the circumferential direction of the inner shaft 310, and the annular groove 314 is located at one end of the inner shaft 310 close to the first rotation shaft 200 and penetrates through the end surface of the inner shaft 310, which corresponds to forming a step on the outer wall of the inner shaft 310.

The opening depth of the annular groove 314 is adapted to the dimensions of the motor carrier.

In other embodiments, the mounting portion 313 may be provided in other forms, such as a structure adapted to the motor carrier and provided on the inner shaft 310, and directly and integrally extended into the motor carrier.

Referring to fig. 3 again, the shaft sleeve 320 is slidably sleeved outside the inner shaft 310 and is used for locking the motor carrier along the axial direction of the motor carrier, specifically, when the motor carrier is mounted on the mounting portion 313, a part of the motor carrier protrudes out of the outer wall of the inner shaft 310, and at this time, the shaft sleeve 320 can abut against the protruding part of the motor carrier and abut against the motor carrier on the first rotating shaft 200.

In other embodiments, the shaft sleeve 320 and the inner shaft 310 may be fixed by a snap connection to achieve a relative displacement, so as to lock the motor carrier in the axial direction of the motor carrier or release the locked state.

Referring to fig. 3, in order to facilitate the operation of the shaft sleeve 320, in some embodiments, the shaft sleeve 320 is provided with a protrusion 322, the protrusion 322 is located at one side of the shaft sleeve 320 close to the limiting portion 312, two ends of the elastic member 400 respectively abut against the limiting portion 312 and the protrusion 322, and when the shaft sleeve 320 needs to be slid, the operation can be performed by pulling the protrusion 322, which is convenient for a worker to operate. Further, a groove 323 may be formed on the outer wall of the sleeve 320, and the groove 323 is adjacent to the protrusion 322, so that when the protrusion 322 is manually operated, there is more holding space, which is convenient for the staff to pull the protrusion 322 to make the sleeve 320 slide relative to the inner shaft 310.

In order to prevent the shaft sleeve 320 from rotating relative to the inner shaft 310 in the process of sliding the shaft sleeve 320 relative to the inner shaft 310, in some embodiments, a limiting groove 321 extending along the axial direction of the inner shaft 310 is formed in the shaft sleeve 320, and the second rotating shaft 300 further includes a limiting pin 340, and the limiting pin 340 is embedded in the limiting groove 321 and connected to the inner shaft 310. The number of the limiting grooves 321 may be one, two, or more, the limiting pin 340 is disposed along the radial direction of the inner shaft 310 and is embedded in the limiting groove 321, and the limiting pin 340 can slide in the limiting groove 321, at this time, the shaft sleeve 320 is limited by the limiting pin 340 and cannot rotate relative to the inner shaft 310, but can still slide relative to the inner shaft 310 along the axial direction of the inner shaft 310.

As an embodiment, referring to fig. 1 and fig. 3, a pin hole 311 is formed on the inner shaft 310, the pin hole 311 penetrates through the inner shaft 310 along a radial direction of the inner shaft 310, and a limit pin 340 penetrates through the pin hole 311. This arrangement provides the advantage of easy removal of the hub 320 and thus the inner shaft 310 at any time. It is understood that in other embodiments, the restraint pin 340 may be directly connected to the outer wall of the inner shaft 310.

In order to achieve the detachable connection between the first rotating shaft 200 and the second rotating shaft 300, which is convenient for disassembly and assembly, in some embodiments, the first rotating shaft 200 and the second rotating shaft 300 are connected by a magnetic connection manner, that is, the first rotating shaft 200 and the second rotating shaft 300 are attracted together by a magnetic force of a magnetic member, and when disassembly is required, the disassembly only needs to be performed by overcoming the magnetic force. The benefits of this approach are: because the magnetic connection does not need to arrange other connecting pieces on the first rotating shaft 200 and the second rotating shaft 300, the motor carrier is convenient to mount and dismount, and the mounting and dismounting are both very convenient.

Specifically, in the present embodiment, the first magnetic member 230 is embedded in the end portion of the first rotating shaft 200 facing the second rotating shaft 300, and the second magnetic member 350 is embedded in the end portion of the inner shaft 310 facing the first rotating shaft 200. At least one of the first magnetic member 230 and the second magnetic member 350 is a magnet or a magnetite, and a surface of the first magnetic member 230 facing the second magnetic member 350 has opposite magnetism to a surface of the second magnetic member 350 facing the first magnetic member 230, so that when the first magnetic member 230 approaches the second magnetic member 350, the two magnetic members can attract and connect with each other.

Specifically, the first magnetic member 230 is disposed on an end surface of the first rotating shaft 200 close to the second rotating shaft 300 and exposed from the receiving hole 220. The second rotating shaft 300 further includes a core shaft 330 and a positioning block 360, the inner shaft 310 is provided with a through hole along the axial direction thereof, the core shaft 330 is sleeved in the through hole, the second magnetic member 350 and the positioning block 360 are both located in the through hole, and the second magnetic member 350 and the positioning block 360 are respectively located at two sides of the core shaft 330 and abut against the core shaft 330. The second magnetic member 350 is close to the first magnetic member 230 and exposed from the end surface of the inner shaft 310, so that the first magnetic member 230 and the second magnetic member 350 can be directly attached together, which can increase the magnetic attraction force between the first magnetic member 230 and the second magnetic member 350, and make the connection between the first rotating shaft 200 and the second rotating shaft 300 more stable. Further, the surface areas of the contacting surfaces of the first and second magnetic members 230 and 350 may be equal and completely coincident, further increasing the coupling force between the first and second magnetic members 230 and 350.

In addition, in order to allow the limit pin 340 to pass through, a clamping groove 331 is arranged in the core shaft 330, and the position of the clamping groove 331 is matched with the position of the pin hole 311, so that the limit pin 340 passes through the clamping groove 331 while passing through the pin hole 311, and at the moment, the core shaft 330 is also limited by the limit pin 340 and cannot rotate relative to the inner shaft 310. In other embodiments, the inner shaft 310 may be a solid structure, and the second magnetic member 350 may be directly embedded in the inner shaft 310.

Referring to fig. 4 and fig. 5, the working principle of the winding jig 100 provided in the present embodiment is as follows: when fixing the motor carrier 500, the first rotating shaft 200 and the second rotating shaft 300 are detached, the motor carrier is mounted on the mounting portion 313, and then the motor carrier is pressed against the receiving hole 220 of the first rotating shaft 200. The motor carrier 500 has a protruding tooth 510 protruding from the motor carrier 500 along the radial direction, and the shaft sleeve 320 abuts against the protruding tooth 510 on the motor carrier 500 along the axial direction of the motor carrier under the elastic pressure of the elastic member 400, so that the motor carrier 500 cannot rotate relative to the inner shaft 310, and at this time, the motor carrier 500 is stably fixed on the winding jig 100, and since the shaft sleeve 320 abuts against the protruding tooth 510, no excessive pressure is generated on the motor carrier 500 in the axial direction. Since there is no fastening force between the second rotation shaft 300 and the screw of the motor carrier 500 although they are in contact with each other in the process of fixing the motor carrier, and a clamping force in the radial direction of the motor carrier 500 is not applied to the outer shape of the motor carrier 500, the motor carrier 500 is not damaged. At this time, the first rotating shaft 200 may be mounted on the winding machine, and the coil may be wound on the motor carrier 500 from a gap between the sleeve 320 and the end surface of the first rotating shaft 200.

In other embodiments, the mounting portion 313 may be disposed at an end of the first rotating shaft 200 facing the inner shaft 310, the motor carrier 500 is mounted on the first rotating shaft 200 during a winding operation, and the bushing 320 locks the motor carrier in an axial direction of the motor carrier after the second rotating shaft 300 is assembled with the first rotating shaft 200. Specifically, at this time, a receiving hole may be formed at an end of the inner shaft 310 facing the first rotating shaft 200, the receiving hole has the same or similar structure as the receiving hole 220 in the above-described embodiment, and a mounting portion 313 may be formed at an end of the first rotating shaft 200 facing the inner shaft 310, and the mounting portion 313 may also be provided in the form of an annular groove 314.

Referring to fig. 6, the present embodiment further provides a winding machine 10, including the winding jig 100 (not shown in fig. 5), a machine body 11, a fixing seat 12 and a driving motor 13, where the fixing seat 12 is disposed on the machine body 11, the fixing seat 12 is provided with a mounting hole (not shown) for mounting the first rotating shaft 200, an aperture of the mounting hole is adapted to an outer diameter of the first rotating shaft 200, the first rotating shaft 200 may be embedded into the mounting hole to form a fixing, and the driving motor 13 is used for driving the fixing seat 11 to rotate, and completing winding in a rotating process. In some embodiments, the mounting hole may also be configured to match with the positioning mounting surface 210, such that when the first rotating shaft 200 is assembled in the mounting hole, the first rotating shaft 200 and the fixing base 12 will not rotate relatively.

The winding machine 10 provided in this embodiment does not damage the motor carrier when performing coil winding operation, and can improve the yield of products during winding operation.
