Description

Technical Field

[0001] The present application relates to the technical field of winding machines, and in particular to a coil winding machine. Background Art

[0002] A wire winding machine is a machine that winds the wire on a wire reel. First, place the wire reel on the frame, make it mesh well with the transmission part, and shake the top cone to tighten it. This can effectively prevent swinging during operation and irregular winding. Then check whether all parts are intact and reliably grounded. After checking, fix any end of the numbered wire on the reel axle, turn on the power and press the triple start button, and the wire will automatically and neatly wind in the wire reel.

[0003] For example, patent publication number CN216957747U discloses a new type of automatic coil winding machine, which passes the wire through the first wire groove, the second wire groove and the third wire groove in sequence, at which time one end of the wire is pressed on one side of the winding drum body, and then the sleeve rod and the sleeve are held, and the length of the sleeve rod is controlled, and then it is rotated around the winding drum body, so that the wire can be evenly wound on the outer surface of the winding drum body.

DETAILED DESCRIPTION

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0038] like Figure 1 and Figure 6 As shown, the present application provides a coil winding machine, comprising a base 1, and a winding portion 4 installed on the base 1, the winding portion 4 is used to perform winding operations on wires;

[0039] The winding part 4 includes a third motor 41 fixedly connected to the base 1, a first clamp 42 is fixedly arranged on one side of the third motor 41, and a bracket 45 is fixedly arranged on the base 1;

[0040] The bracket 45 is threadedly connected with a screw rod 47, and a second clamp 44 is rotatably provided on a side of the screw rod 47 close to the first clamp 42, and a locking portion 46 is fixedly connected to a side of the screw rod 47 away from the second clamp 44, so that the screw rod 47 can be rotated by the locking portion 46 to make the second clamp 44 close to or away from the first clamp 42;

[0041] A winding roller 43 is provided between the first clamp 42 and the second clamp 44. The winding roller 43 is clamped by the first clamp 42 and the second clamp 44 to facilitate the stability of the wire winding. At the same time, the movement of the position of the second clamp 44 by the locking portion 46 facilitates the disassembly and assembly of the winding roller 43.

[0042] like Figure 1-Figure 2 As shown, a first adjusting portion 2 is installed on the upper end of the base 1, and the first adjusting portion 2 is used to perform preliminary guidance and tension control on the wire;

[0043] The first adjusting part 2 includes a first slide rail 21 fixedly connected to the upper end of the base 1, a first slider 22 is slidably connected to the upper end of the first slide rail 21, and three sets of tensioning wheels 23 are installed on the upper end bearing of the first slider 22. The three sets of tensioning wheels 23 constitute a channel for wire transmission, so as to tension the wire when the wire is rolled;

[0044] A first motor 26 is fixedly arranged on one side of the first slide rail 21, and a lead screw (not shown in the figure) is fixedly installed on the output end of the first motor 26, and is transmission-connected with the first slider 22 and the lead screw, so that when the first motor 26 is in operation, the first slider 22 can be driven to move along the direction of the first slide rail 21 to adjust the position of the wire winding;

[0045] like Figure 1 and Figure 3-Figure 5 As shown, a second adjusting portion 3 is provided on the base 1 between the first adjusting portion 2 and the winding portion 4 and close to the winding portion 4. The second adjusting portion 3 is used to guide the wire and control the tension when the wire transmission is coming to an end.

[0046] The second adjusting portion 3 includes a supporting portion 32 fixedly connected to the first slide rail 21, the supporting portion 32 is used to support the second adjusting portion 3, a second slide rail 33 is fixedly provided on the supporting portion 32, a second slider 35 is slidably connected to the second slide rail 33, and a tightening portion 34 is fixedly connected to the upper end of the second slider 35. When the wire passes through the tightening portion 34, the first slider 22 moves to drive the second slider 35 to move along the direction of the second slide rail 33;

[0047] The tightening part 34 includes a support frame 349 fixedly mounted on the second slider 35, a cylinder 341 is fixedly mounted on the upper end of the support frame 349, and a slide groove 342 is arranged on the outer wall of the cylinder 341, and a third slide rail 347 is arranged outside the slide groove 342, and a third slider 344 is slidably connected to the third slide rail 347, and a second motor 343 is arranged on one side of the third slide rail 347, and a lead screw (not shown in the figure) is fixedly mounted on the output end of the second motor 343, and is transmission-connected to the third slider 344 and the lead screw, and when the second motor 343 is in operation, the third slider 344 can be driven to move along the direction of the third slide rail 347;

[0048] At the same time, an elastic chuck 345 is installed inside the cylinder 341, and the elastic chuck 345 is divided into a fixed section and an elastic contraction section;

[0049] The fixing section is used to be fixedly connected to the inner wall of the cylinder 341. At the same time, the outer ring of the elastic clamp 345 is provided with a tightening ring 346 near the fixing section. The tightening ring 346 is fixedly connected to the third slider 344, so that the tightening ring 346 can move synchronously with the movement of the third slider 344.

[0050] Meanwhile, the elastic contraction section is composed of a plurality of metal springs, which are circumferentially distributed at the beginning of the elastic clamp 345, and a through hole 351 is formed inside the metal spring;

[0051] It can be understood that when the metal spring is in a relaxed state, the diameter of the through hole 351 will be larger than the outer diameter of the wire, so as to facilitate the passage of the wire. On the contrary, when the metal spring is in a contracted state, the diameter of the through hole 351 will be smaller than the outer diameter of the wire, so as to facilitate the clamping of the wire by the through hole 351.

[0052] In this embodiment, a rubber protective layer may be provided at the contact points between the multiple groups of metal springs and the wires to prevent scratches on the wires;

[0053] A tightening block 350 is provided at one end of the plurality of metal spring sheets away from the fixed section. The diameter of the tightening block 350 gradually decreases from the opening end along the wire conveying direction. Meanwhile, the minimum diameter of the tightening block 350 is smaller than the diameter of the fixed section, so that the tightening ring 346 can reach the outer ring of the tightening block 350 from the fixed section.

[0054] When the tightening ring 346 reaches the large diameter of the outer ring along the small diameter of the outer ring of the tightening block 350, since the inner diameter of the tightening ring 346 is fixed, it will drive multiple groups of metal springs to move inward and tighten the wire.

[0055] In summary: when the wire is wound to the end, the wire will be separated from the first adjusting part 2, so that the wire will lose its initial tension. At this time, the second motor 343 of the tightening part 34 will operate to drive the third slider 344 to move along the direction of the third slide rail 347, so that the tightening ring 346 fixed to the third slider 344 can move synchronously with the movement of the third slider 344;

[0056] The tightening ring 346 reaches the outer ring of the tightening block 350 from the fixed section. When the tightening ring 346 reaches the outer ring of the tightening block 350 from the smaller diameter of the outer ring of the tightening block 350 to the larger diameter of the outer ring of the tightening block 350, the wire can be tightened because the inner diameter of the tightening ring 346 is fixed.

[0057] Finally, the winding unit 4 is used for winding.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
