DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] A magnetic ring clamping device for a winding machine comprises a supporting mechanism and a clamping mechanism capable of clamping magnetic rings 501 of different sizes, wherein the supporting mechanism comprises a base plate 101, a plurality of telescopic rods 102 and a supporting plate 103, wherein the base plate 101 is detachably arranged on a workbench of the winding machine, and the supporting plate 103 is connected to the base plate 101 via the plurality of telescopic rods 102; the clamping mechanism is arranged on the supporting plate 103, and the clamping mechanism comprises three linked clamping units, wherein the supporting plate 103 is provided with three elongated holes 201 distributed in a circular array, and the extension directions of the three elongated holes 201 intersect at one point; and the moving parts of the three clamping units can respectively move synchronously in the three elongated holes 201.

[0023] In some implementations of the present embodiment, any clamping unit includes a driving mechanism 202 arranged on the support plate 103, a sleeve 203 slidably arranged in the corresponding elongated hole 201, a clamping rod 204 rotatably connected to the sleeve 203, and a rubber wheel arranged at the top of the clamping rod 204, the driving mechanism 202 is used to drive the sleeve 203 to move back and forth in the elongated hole 201, and the three driving mechanisms 202 work synchronously; both ends of the clamping rod 204 extend out of the sleeve 203, and the central axes of the three clamping rods 204 are parallel to each other.

[0024] Since the magnetic ring 501 needs to rotate during the winding process to cooperate with the relevant mechanisms of the winding machine to wind the wire around the magnetic ring 501, the bottom end of one of the clamping rods 204 is connected to the drive motor 205. When the magnetic ring 501 is clamped by the three rubber wheels, the drive motor 205 starts to work to control the clamping rod 204 connected to it to rotate around its own axis. The rotation of the clamping rod 204 will drive the rubber wheel installed thereon to rotate. The rotation of the rubber wheel drives the magnetic ring 501 to rotate under the action of friction. The control method for controlling the synchronous action of the three drive mechanisms 202 belongs to the prior art and will not be repeated here.

[0025] In some implementations of this embodiment, the rubber wheel includes a limiting column 206 and a lower limiting ring 207, the bottom end of the limiting column 206 is connected to the top end of the clamping rod 204, the lower limiting ring 207 is arranged at the bottom end of the limiting column 206, and the outer diameter of the lower limiting ring 207 is greater than the diameter of the limiting column 206. The three lower limiting rings 207 form a bearing platform with a supporting function to place the magnetic ring 501 to be wound.

[0026] In some implementations of this embodiment, an upper limit ring 301 is further provided at the top of the limit post 206, the outer diameter of the upper limit ring 301 is larger than the diameter of the limit post 206, and an adjustment post 302 is provided on the upper limit ring 301, and the adjustment post 302 is threadedly connected to the limit post 206. This design allows magnetic rings 501 of different thicknesses to be placed between the three rubber wheels. When in use, the upper limit ring 301 is screwed to drive the adjustment post 302 to rotate, so that the distance between the upper limit ring 301 and the lower limit ring 207 is adapted to the thickness of the current magnetic ring 501.

[0027] When the magnetic ring 501 to be wound is clamped by the three rubber wheels, one of the rubber wheels rotates under the control of the driving motor 205 to drive the magnetic ring 501 to rotate during the winding process. In order to increase the friction between the rubber wheel and the magnetic ring 501, so that the magnetic ring 501 rotates smoothly under the drive of the rubber wheel, a plurality of grooves are specially provided on the outer wall of the limiting column 206. The grooves can increase the friction between the magnetic ring 501 and the limiting column 206 of the rubber wheel.

[0028] Since the distances between the relevant winding mechanisms of different winding machines and the working tables of the winding machines are different, the clamping heights of the three rubber wheels can be adjusted by adjusting the length of the telescopic rod 102 when necessary, so that the clamping device can be adapted to different winding machines.

[0029] In some implementations of this embodiment, the driving mechanism 202 is a hydraulic cylinder, and the execution end of the driving mechanism 202 is connected to the corresponding sleeve 203. The hydraulic cylinder is used here to take advantage of its easy control of objects to achieve linear motion. In other implementations of this embodiment, the driving mechanism 202 can also use a screw nut mechanism and a linear motor to control the movement of the sleeve 203.

[0030] In order to facilitate the sliding of the sleeve 203 in the elongated hole 201, the two inner side walls of any elongated hole 201 are provided with a rolling track 401 and an avoidance track 402, the extension direction of the rolling track 401 and the extension direction of the avoidance track 402 are the same as the extension direction of the elongated hole 201, and the rolling track 401 and the elongated hole 201 are connected through the avoidance track 402; a roller 403 is provided in the rolling track 401, and a rotating shaft 404 is provided in the avoidance track 402, one end of the rotating shaft 404 is connected to the sleeve 203, and the other end is rotatably connected to the roller 403.

[0031] Working principle:

[0032] When clamping, first set the parameters of the hydraulic cylinder according to the size of the magnetic ring 501, so that the hydraulic cylinder stops extending when the three limit columns 206 just clamp the magnetic ring 501. Then place the magnetic ring 501 between the three rubber wheels, start the control mechanism to control the three hydraulic cylinders to extend simultaneously, so that the three rubber wheels move toward the magnetic ring 501 at the same time, and when the three rubber wheels clamp the magnetic ring 501, the three hydraulic cylinders stop extending and maintain the current state. After the magnetic ring 501 is clamped, the drive motor 205 starts to work to control the clamping rod 204 connected to it to rotate around its own axis. The rotation of the clamping rod 204 will drive the rubber wheel installed thereon to rotate. The rotation of the rubber wheel drives the magnetic ring 501 to rotate under the action of friction. During the rotation of the magnetic ring 501, the relevant mechanism of the winding machine will wind the wire around the magnetic ring 501.

[0033] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
