The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application.
Referring to fig. 1 to 7, the present application is a vertical multi-specification winding machine, which has a frame 1, wherein the frame 1 is provided with:
the winding device 3 is provided with a vertical winding die and a first driving mechanism for driving the winding die to rotate, and a plurality of winding sections with different peripheral diameters are arranged on the winding device 3 in an up-down arrangement mode and are used for winding coils with different peripheral diameters;
and the wire passing mechanism 2 is in butt joint with the winding mould and is used for guiding the enameled wires into different winding sections.
By adopting the winding machine with the structure, the enamelled wire is conveyed to the corresponding winding section through the wire passing mechanism 2, the winding of coils with different diameters can be realized through the rotation of the winding mould, and the winding sections with different diameters are arranged on the winding mould, so that the wire passing mechanism 2 can be used for winding the coil with a single diameter corresponding to the winding section with the required diameter according to production requirements, and the coils with different diameters can be wound by moving to the winding sections with different diameters in the winding process. The problem that only can wind single week footpath, specification coil on traditional equipment can be solved, the practicality is strong, helps improving production efficiency, reduction in production cost, and then improves the market competition of product.
Preferably, the winding device 3 is provided with a wire clamping mechanism at the upper end of the winding die, and the wire clamping mechanism is used for clamping the wire head or the wire tail of the coil wound on the winding wire section.
In order to realize the rotation of the winding mold, the winding device 3 has a spindle 305 penetrating the frame 1, the first driving mechanism is mounted on the frame 1 and is in transmission connection with the upper end of the spindle 305 to control the spindle 305 to rotate around the axis thereof, the winding mold is mounted at the lower end of the spindle 305, and the wire clamping mechanism is sleeved on the spindle 305.
Considering that the winding die needs to rotate to wind the coil, if the wire clamping mechanism is directly and fixedly mounted on the main shaft 305 to rotate along with the main shaft, the load of the first driving mechanism is increased, and the rotation of the winding die is easily affected. The thread clamping mechanism performs thread clamping operation, and therefore, the thread clamping mechanism inevitably has an opening and closing function, and if the thread clamping mechanism rotates along with the spindle 305, the line arrangement of the executing mechanism of the related starting operation is inconvenient.
Considering the above, as shown in fig. 3 to 5, the wire clamping mechanism includes a wire clamping assembly sleeved on the spindle 305 and a second driving mechanism installed on the frame 1 and used for controlling the operation of the wire clamping assembly, the wire clamping assembly includes a wire clamping slide 318 fixed in horizontal position relative to the spindle 305, a plurality of wire clamping holders 310 circumferentially distributed along the spindle 305 and installed on the wire clamping slide 318 in a manner of being capable of sliding along the spindle 305 in radial direction, and first push rods 314 installed vertically in one-to-one correspondence with the wire clamping holders 310, wherein the wire clamping holders 310 are provided with wire clamping columns 311 extending outside the wire clamping slide 318 and being capable of being attached to the side walls of the wire clamping slide 318, a reset spring 319 is provided between the wire clamping slide 318 and the wire clamping holders 310, the wire clamping holders 310 are enabled to abut against the side walls of the wire clamping slide 318 by the action of the reset spring 319, the upper ends of the wire clamping holders 310 are provided with conical surfaces, the lower ends of the first push rods 314 are aligned with the conical surfaces, and the second driving mechanism is provided with a transmission part connected with the upper ends of the first push rods 314, so that when the first push rods 314 are independently pushed down the wire clamping holders 310, the wire clamping holders 310 are prevented from being pushed down relative to the side walls of the frame 310, and the wire clamping holders are enabled to be separated from the side walls of the frame 310 by sliding.
Because each first push rod 314 only pushes one wire clamping seat 310, when the coils are taken down after the coils are wound on the winding mold, all the first push rods 314 need to be controlled to push the wire clamping seats 310 together so as to loosen the wire heads and the wire tails of all the coils, and the process is complicated.
As shown in fig. 1, the frame 1 includes a first mounting plate 101 and a second mounting plate 102 disposed up and down, the first mounting plate 101 is erected above the second mounting plate 102 by a support bar, and a lower end of the second mounting plate 102 is also provided with a support bar for supporting the entire winding machine. The main shaft 305 is provided with a bearing and is vertically arranged on the first mounting plate 101 through the bearing, the synchronous wheel 316 is fixedly arranged outside the upper end of the main shaft 305, the first driving mechanism comprises a first driving motor arranged on the first mounting plate 101, the output shaft of the first driving motor is provided with a driving wheel, and the driving wheel is connected with the synchronous wheel 316 through belt transmission or directly meshed with the synchronous wheel 316, so that the main shaft 305 is controlled to rotate.
The corresponding wire clamping mechanism mainly comprises three specific installation modes, wherein the first installation mode is as follows: the wire clamping slide seat 318 is fixedly arranged below the first mounting plate 101, the wire clamping seat 310 and the reset spring 319 are correspondingly arranged on the wire clamping slide seat 318, the transmission part of the second driving mechanism corresponding to the first push rod 314 is a first driving cylinder vertically arranged on the first mounting plate 101, the first push rod 314 is fixed at the output end of the first driving cylinder, a plurality of second push rods 313 are arranged at the upper end of the wire clamping top ring 312, and the third driving mechanism is a second driving cylinder vertically arranged on the first mounting plate 101 and connected with the upper end of the second push rod 313. The clamp top ring 312 may be supported by the clamp base 310 or by the first mounting plate 101 by fixedly connecting the second push rod 313. So configured, the entire wire clamping mechanism is fixed to the frame 1 and does not rotate with the spindle 305.
The second mounting mode is as follows: the wire clamping slide seat 318 is fixedly installed on the main shaft 305, the upper end face of the wire clamping slide seat 318 is set to be a plane, a limiting ring is placed at the upper end of the wire clamping slide seat, a mounting chute of the wire clamping seat 310 is formed in the limiting ring, the wire clamping seat 310 is installed between the limiting ring and the wire clamping slide seat 318 and can slide along the mounting chute, and the reset spring 319 is installed in the mounting chute. And the first push rod 314 and the clamp coil top ring 312 are installed in the same manner as the first installation method. So configured, the thread clamping slide 318 of the thread clamping mechanism rotates along with the spindle 305, while the thread clamping seat 310, the limiting ring and other components are fixed relative to the frame 1 and cannot rotate along with the frame.
The third mounting mode is: the clamping slide 318 is fixedly mounted on the spindle 305, the clamping seat 310 and the return spring 319 are mounted on the clamping slide 318, and a certain gap is reserved between the first push rod 314 and the clamping top ring 312 and the clamping seat 310. In this way, the clamping slide 318, the clamping seat 310 and the return spring 319 rotate with the spindle 305, while the first push rod 314 and the clamping top ring 312 are fixed relative to the frame 1, do not rotate therewith, and only move downward during operation to butt against the clamping seat 310.
Since the coil wound on the winding section is in a tight state and is difficult to take off, in order to facilitate the taking out of the coil, further, the winding mold comprises a front mold 302 and a rear mold 301 which are vertically arranged, and the front mold 302 and/or the rear mold 301 are movably mounted at the lower end of the main shaft 305 so that the front mold 302 can be close to or far from the rear mold 301. Thus, after the winding of the coil is completed, the front mold 302 and the rear mold 301 are controlled to be close to each other, so that the tightening state of the coil can be relieved, and the coil can be taken out conveniently.
Specifically, as shown in fig. 4, a winding mounting seat 317 is fixedly disposed at the lower end of the main shaft 305, a horizontal mounting through groove is disposed at the lower end of the winding mounting seat 317, a horizontal adjusting gear ring 308 is disposed in the winding mounting seat 317 in a rotating manner, the lower end surfaces of the adjusting gear ring 308 extend into the mounting through groove and are provided with end surface threads, the upper ends of the front mold 302 and the rear mold 301 are provided with a front mold sliding seat 306 and a rear mold sliding seat 307 and are mounted in the mounting through groove, the upper end surfaces of the front mold sliding seat 306 and the rear mold sliding seat 307 are provided with end surface threads matched with the adjusting gear ring 308, the adjusting gear ring 308 is provided with transmission teeth 309 extending outside the winding mounting seat 317, and meanwhile, when the adjusting gear ring 308 is mounted at the lower end of the winding mounting seat 317, a wire taking space is reserved between the front mold 302 and the rear mold 301. The front mold 302 and the rear mold 301 can be controlled to be close to or far away from each other by controlling the rotation of the adjusting gear ring 308, so that the device can be used for releasing the tightening of the coil, and can also be used for adjusting the peripheral diameter of a winding section formed by the front mold 302 and the rear mold 301, thereby enlarging the application range and having strong practicability. In view of the inconvenience of adjusting the gear ring 308, in the above-mentioned structure, a wire-withdrawing chute parallel to the mounting through slot is formed on the rear mold sliding seat 307 in the present embodiment, the rear mold 301 is slidably mounted in the wire-withdrawing chute, and meanwhile, a push spring 315 is disposed in the wire-withdrawing chute at one end of the rear mold 301 close to the front mold 302. Therefore, after the coil is wound, the rear die 301 is pushed to press the push spring 315 to be close to the front die 302, so that the distance between the two dies can be reduced, the tightening state of the coil is relieved, the coil is conveniently taken out, and then the rear die 301 can be automatically reset after being pushed by loosening the push spring, so that the coil winding device is convenient to use and high in practicability. In addition, a wire-taking space is reserved between the front mold 302 and the rear mold 301, and after the tightening state of the coil is released, the coil can be taken out from the wire-taking space, so that convenience and rapidness are realized.
Further, as shown in fig. 2, the front mold 302 and the rear mold 301 are aligned with each other to form a vertical line-escape groove 304. The wire-pushing rod 303 is installed at the upper end of the wire-withdrawing groove 304 to push out the coil wound on the front mold 302 and the rear mold 301. In order to realize the vertical movement of the wire pushing rod 303, in this embodiment, the main shaft 305 is configured to be a hollow structure, a connecting rod is inserted into the main shaft 305, the lower end of the connecting rod is connected to the wire pushing rod 303, the upper end of the connecting rod extends to the upper end of the first mounting plate 101, meanwhile, the upper end of the first mounting plate 101 corresponds to a third driving cylinder arranged on the connecting rod, after the winding of the coil is completed and the tightening state of the coil is released, the connecting rod is pressed down by the third driving cylinder, and the wire pushing rod 303 is controlled to move downwards to push the coil out. The actual length of the push rod 303 may be set as needed, so that it may extend outside the front mold 302 and the rear mold 301 in the winding stage, or may extend outside the front mold 302 and the rear mold 301 only when the coil tension is released, and this will not be described in detail. Because the front mold 302 and the rear mold 301 will rotate along with the main shaft 305, the components such as the rotary coupling and the like can be arranged between the third driving cylinder and the connecting rod to realize the butt joint, and the rotation of the third driving cylinder is avoided.
As shown in the figure, in order to make the winding of each group of coils uniform in the winding process of the winding mould, each winding section is coaxially arranged so that the rotation centers of the winding sections are consistent. And the plurality of winding segments are arranged in a mode that the circumference diameter of the winding segments is sequentially reduced from top to bottom. Because the wire end is clamped on the wire clamping slide seat 318 at the upper end of the winding mould, in order to avoid the enameled wire from being pulled out upwards from the corresponding winding section in the winding process, the winding mould is provided with an anti-drop structure at the upper end of each winding section. Specifically, since the peripheral diameters of two adjacent winding sections are reduced, a step is formed between the outer surfaces of the two adjacent winding sections, in this embodiment, a notch is machined at the end face of the step, and the enameled wire is clamped on the wire clamping slide seat 318, so that the enameled wire is limited by the notch at the upper end of the corresponding winding section, and is prevented from falling off, so that an anti-falling structure is formed.

In this way, the lifting mounting seat is formed by the wire passing mounting seat 201, the movable plate 202 and the wire passing mounting plate 203, so that the wire clamp has a triaxial movement function, and the enameled wire is clamped by the wire clamp in the non-working state of the winding machine. When the winding machine works, the enameled wire is guided to the wire clamping mechanism through the wire clamp movement so as to clamp the wire head or the wire tail, the enameled wire is abutted against winding sections with different peripheral diameters, notches at the upper ends of the winding sections, and the like, and the winding machine does not need to move up and down through a winding die, so that the stability of the operation of the winding die is improved.
