Description

Technical Field

[0001] This utility model relates to coil winding device technology, specifically to an electromagnetic coil magnetic attraction winding device. Background Technology

[0002] Existing winding devices use a threaded fixing method for winding coils. The guide shaft on the winding device needs to pass through a through hole in the winding post and be fixed at the other end with a nut to drive the winding post to rotate. Existing winding devices require a separate winding post with a through hole so that the guide shaft on the winding device can pass through the winding post and be locked at the other end with a nut. The existing device has a relatively narrow range of applications, requires a winding post with a through hole, and has a slow nut locking speed, resulting in low efficiency. Since the winding post is generally made of plastic, it is prone to deformation after locking. Utility Model Content

[0003] Purpose of the utility model: This utility model provides an electromagnetic coil magnetic attraction winding device, which has a wide range of applications and solves the problem of easy slippage and detachment during the winding process.

[0004] Technical solution: The present invention proposes an electromagnetic coil magnetic attraction winding device, including a winding shaft seat and a guide shaft located at the front center of the winding shaft seat base; a circular magnet is provided at the front end of the winding shaft seat base, and a plurality of cylindrical magnets are provided inside the winding shaft seat.

[0005] Preferably, the base of the winding shaft seat has a groove at its front end for placing a circular magnet.

[0006] Preferably, a guide pin is also provided, the guide pin being located on both sides of the guide shaft, the guide shaft being located inside the annular magnet, and the guide pin being located outside the annular magnet.

[0007] Preferably, the depth of the groove is the same as the height of the annular magnet.

[0008] Preferably, a plurality of the cylindrical magnets are fixed inside the winding shaft seat by a magnet positioning sleeve.

[0009] Preferably, the magnet positioning sleeve is fixed inside the winding shaft seat by a plurality of set screws.

[0010] Preferably, a buffer sleeve is provided between the magnet positioning sleeve and the winding shaft seat.

[0011] Beneficial effects: The device proposed in this utility model utilizes magnetic attraction to fix the winding assembly for coil winding, which is simple, labor-saving, and fast to install. This device has a wide range of applications and can be used for electromagnetic coils wound directly on the coil core, without requiring a winding post with a through hole. The device has a guide shaft and guide pin to limit the winding assembly, and the cylindrical magnet can be adjusted to regulate the magnetic attraction force, preventing the winding assembly from slipping or falling off during rotation.

[0015] See Figures 1 to 3 As shown, this utility model discloses an electromagnetic coil magnetic winding device, including a winding shaft seat 1, a circular magnet 2, a cylindrical magnet 3, a magnet positioning sleeve 4, a buffer sleeve 5, and a set screw 6. The winding shaft seat is made of metal, preferably carbon steel. A groove is formed at the front end of the base of the winding shaft seat 1 to hold the circular magnet 2. The depth of the groove is the same as the height of the circular magnet 2, allowing the circular magnet 2 to be embedded in the groove, thus generating magnetism on the bottom surface of the winding shaft seat 1. A guide shaft 11 is located at the center of the front end of the base of the winding shaft seat 1. Guide pins 12 are provided on both sides of the guide shaft 11. The guide shaft 11 is located inside the circular ring of the circular magnet 2, and the guide pins 12 are located outside the circular magnet 2. The guide pins limit the winding assembly during subsequent winding. A set of cylindrical magnets 3 are also placed inside the winding shaft seat 1. They can couple with the magnetic field of the front ring magnet 2 to adjust the magnetic field strength on the bottom surface of the winding shaft seat 1 and the guide shaft 11, thereby increasing the magnetic force. During the subsequent winding process, the coil core in the winding column assembly can be firmly attracted to the bottom surface of the winding shaft seat 1. A magnet positioning sleeve 4 is provided at the rear end of the cylindrical magnet 3 to fix the position of the cylindrical magnet 3 inside the winding shaft seat 1. A buffer rubber sleeve 5 is fitted on the outside of the magnet positioning sleeve 4 to provide a buffering effect when the winding device rotates at high speed, preventing the cylindrical magnet 3 from shifting or breaking.

[0016] The installation sequence of the magnetic winding device is as follows: First, the circular magnet 2 is attracted into the front groove of the winding shaft seat 1. Then, a set of cylindrical magnets 3 are installed into the magnet positioning sleeve 4 with the same magnetic pole direction as the circular magnet 3. The outer side of the magnet positioning sleeve 4 is covered with a buffer rubber sleeve 5. Then, the entire assembly is inserted into the inner hole of the winding shaft seat to the bottom and fixed with a set screw 6. The specific usage procedure is as follows: First, the magnetic winding device is installed on the output shaft of the winding machine. Then, the winding shaft of the coil winding assembly is aligned with the guide shaft 11 on the winding shaft seat and pushed all the way down. After the hole on the winding shaft base engages with the guide pin 12, the coil is limited, so that the coil core is attracted to the winding shaft seat 1. Then, the machine is turned on to wind the coil.
