Description

Technical Field

[0001] The utility model belongs to the technical field of wire winding, and in particular relates to a wire winding machine. Background Art

[0002] As a special equipment, the winding machine is used to wind the wire on a core of a specific shape, thereby forming the basic structure of electronic components such as inductors and transformers. The traditional winding process first puts the core on the driving end of the driving device, and then the driving device drives the core to rotate to complete the winding. Since the inner diameter of each core has a certain deviation, when the driving device drives the core to rotate, the core and the driving device will also rotate relative to each other, or the core is easy to detach from the driving device, resulting in the number of winding turns not being consistent with the expected number of turns, affecting the processing quality, or detaching from the driving device, which is prone to safety accidents. Therefore, in existing winding machines, a fixing device is provided on the driving device to fix the core, but the existing fixing devices are all fixed on the outside of the core, which is easy to scratch the core, and the installation method is not only inefficient, but also labor-intensive and easy to cause fatigue of workers and increase the error rate.

[0003] In summary, the existing winding machine technology still has a lot of room for improvement in improving the level of automation and ease of operation. Therefore, the development of a winding machine that can facilitate the loading and unloading of winding cores has important practical significance and market demand. Utility Model Content

[0004] The purpose of the present utility model is to provide a winding machine, which aims to solve the technical problems in the prior art that the core and the driving device may rotate relative to each other, or the core may easily separate from the driving device, resulting in the number of winding turns not being consistent with the expected number of turns, affecting the processing quality, or the core may easily cause a safety accident when separated from the driving device and the existing fixing device may easily damage the core.

[0005] In order to achieve the above-mentioned purpose, an embodiment of the present invention provides a winding machine, comprising a driving device, a reeling device and a mounting jig. The mounting jig is arranged at the driving end of the driving device, and the reeling device is arranged above the driving device. The driving device is used to drive the mounting jig to rotate, and the reeling device is used to unwind. The mounting jig comprises a mounting shaft and a connecting shaft, one end of the connecting shaft is connected to the driving device, and the other end is connected to the mounting shaft, and the axes of the mounting shaft and the connecting shaft are located on the same straight line. A plurality of mounting holes are provided on the mounting shaft, and each mounting hole is arranged in a circular array on the outside of the mounting shaft, and each mounting hole extends along the outside of the mounting shaft into the mounting shaft. An elastic member and a ball are also provided in the mounting hole, and the two ends of the elastic member are respectively connected to the bottom of the mounting hole and the ball, and the ball is slidably arranged in the mounting hole and one end of the ball extends to the outside of the mounting hole.

[0006] Furthermore, a limiting ring is provided inwardly extending from one end of the mounting hole close to the outer side of the mounting shaft, and the inner ring diameter of the limiting ring is smaller than the diameter of the ball.

[0007] Furthermore, the mounting fixture is provided with a connecting hole that extends through the mounting fixture and is located on its centerline. A screw passes through the connecting hole to connect to the drive device. The connecting shaft is also provided with a plurality of threaded holes, each of which is arranged in a circular array on the outside of the connecting shaft. Each threaded hole extends from the outside of the connecting shaft into the inside of the connecting shaft and is connected to the connecting hole.

[0008] Furthermore, the driving device includes a transmission shaft, a driving motor and an installation box. The driving motor is arranged in the installation box. The transmission shaft is rotatably connected to one side of the installation box, and one end of the transmission shaft extends to the outside of the installation box and is connected to the installation fixture. The other end of the transmission shaft is transmission-connected to the driving motor, and the driving motor drives the transmission shaft to rotate.

[0009] Furthermore, the driving device also includes a stabilizing mechanism, which includes a bushing and several support columns. The bushing is mounted on a transmission shaft extending to the outside of the mounting box. Each support column is centered on the bushing, and the annular array is at the side end of the bushing, and the outside of the bushing is connected to each support column.

[0012] The above one or more technical solutions in a winding machine provided by an embodiment of the present invention have at least one of the following technical effects: the mounting jig is mounted on the driving end of the driving device, and the driving device drives the mounting jig to rotate during movement. When the core body is to be wound, the core body is sleeved in the mounting jig. Different mounting jigs are replaced according to core bodies of different specifications, which can greatly reduce the probability of the core body and the mounting jig sliding against each other. At the same time, when the core body is sleeved on the mounting shaft of the mounting jig, the inner side of the core body is slidably connected to the mounting shaft, and at the same time, the core body abuts against the ball bearing, and the ball bearing squeezes the elastic part. The elastic part compresses and stores elastic potential energy, so that the ball bearing presses the core body to avoid the core body from slipping with the mounting jig during rotation. The ball bearing can avoid scratching the inner side of the core body and can better position the core body. The installation method is simple and convenient. After installation, the core body is firm and not easy to slip with the mounting jig, thereby improving the winding quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In one embodiment of the present invention, reference Figures 1 to 3As shown, a winding machine is provided, comprising a driving device 100, a reeling device 200 and a mounting fixture 300. The mounting fixture 300 is arranged at the driving end of the driving device 100, and the reeling device 200 is arranged above the driving device 100. The driving device 100 is used to drive the mounting fixture 300 to rotate, and the reeling device 200 is used to unwind. The mounting fixture 300 includes a mounting shaft 310 and a connecting shaft 320. One end of the connecting shaft 320 is connected to the driving device 100, and the other end is connected to the mounting shaft 310. The axis centers of the mounting shaft 310 and the connecting shaft 320 are located on the same straight line. A plurality of mounting holes 311 are provided on the mounting shaft 310.

An elastic member 312 and a ball 313 are also provided in the mounting hole 311. The two ends of the elastic member 312 are respectively connected to the bottom of the mounting hole 311 and the ball 313. The ball 313 is slidably arranged in the mounting hole 311 and one end of the ball 313 extends to the outside of the mounting hole 311. The cam 312 of the second drive mechanism 313 is pressed against the support member 314 and the support member 316 is pressed against the support member 317 to prevent the cam 312 from slipping against the support member 316 during rotation.

[0023] Specifically, refer to Figures 1 to 3 As shown, a retaining ring 314 extends inward from one end of the mounting hole 311 near the outside of the mounting shaft 310.
