When in use, the winding piece 3 is driven to rotate by the rotating shaft 2 to wind the copper wire. The clamping arm 6 is pressed by pressing the elastic piece, so that the two groups of clamping arms 6 rotate inward and clamped on the outside of the winding piece 3, so that the wire pressing roller 13 presses the winding part of the copper wire for regular winding. Pressing and regularizing are performed from two points.

[0042] Embodiment 2

[0043] according to Figure 1 , 2 As shown in , 3, 4, 5, 6, and 7, this embodiment proposes a method for using a wire pressing auxiliary device of a transformer winding machine, comprising the following steps:

[0044] Pass one end of the copper wire through the wire tube 14 and wind it onto the winding member 3, rotate the rotating shaft 2 to drive the winding member 3 to rotate, and wind the copper wire;

[0045] The second spring 20 squeezes the support leg 18, so that the rotating ring 17 rotates, and the clamping arm 28 presses the clamping arm 6, so that the two groups of clamping arms 6 rotate inward and clamp on the outside of the winding member 3, and the wire pressing roller 13 presses the winding part of the copper wire to make it regular; press and regularize from two points;

[0046] The copper wire passes between the two sets of cleaning rollers 8, and the first spring 12 pushes the T-shaped square column 9, so that the mounting plate 10 moves inward, and the two sets of cleaning rollers 8 clamp the copper wire for cleaning;

[0047] The copper wire passes between two groups of clamping rollers 7, and the first spring 12 pushes the T-shaped square column 9, so that the mounting plate 10 moves inward, and the two groups of clamping rollers 7 clamp the copper wire for regularization; the copper wire passes between two groups of cleaning rollers 8, and then passes between two groups of clamping rollers 7, and the first spring 12 pushes the T-shaped square column 9, so that the mounting plate 10 moves inward, and the two groups of cleaning rollers 8 and two groups of clamping rollers 7 clamp the copper wire for cleaning and regularization, thereby improving the quality of the copper wire, diversifying the functions, and ensuring the winding effect;

[0048] The motor 26 drives the screw rod 27 to rotate, and the screw rod 27 drives the slide rod 4 to move and change its position in the sleeve 24 through the action of the thread, thereby adjusting the position of the winding and performing variable turn winding. The functions are more comprehensive.

[0049] The elasticity of the second spring 20 is greater than that of the first spring 12. While the wire pressing rollers 13 at one end of the two clamping arms 6 are pressed against the copper wire, the two cleaning rollers 8 and the two clamping rollers 7 are in close contact, so that the copper wire is processed normally.

[0050] The present invention drives the winding member 3 to rotate by the rotating shaft 2 to wind the copper wire, and presses the clamping arm 6 by pressing the elastic member, so that the two groups of clamping arms 6 rotate inward and clamp on the outer side of the winding member 3, so that the wire pressing roller 13 presses the winding part of the copper wire for regular winding, and presses and regularizes from two points.

Since the elasticity of the pressing elastic member is greater than the elasticity of the first spring 12, while the wire pressing roller 13 at one end of the two groups of clamping arms 6 presses the copper wire, the two groups of cleaning rollers 8 and the two groups of clamping rollers 7 are in close contact, thereby maintaining normal processing of the copper wire. At the same time, the product drives the screw rod 27 to rotate through the motor 26, and the screw rod 27 drives the slide rod 4 to move and change its position in the sleeve 24 through the thread action, thereby adjusting the position of the winding and performing variable turn winding, with more comprehensive functions.
