[0002] In the fields of power systems, industrial automation, industrial machinery, new energy, etc., the operating current of the equipment is relatively large, and the electromagnetic components of the related equipment require a larger wire diameter to carry the corresponding large current. As one of the electromagnetic components, the toroidal inductor also requires a larger wire diameter for winding during product design and production.

[0003] In the production of large-diameter toroidal inductors, coil winding is basically done manually. During the production work, the different physical strength of operators and the impact of working hours on physical strength cause differences in winding tension and wire arrangement tightness, resulting in poor consistency of electrical characteristics such as product impedance and leakage inductance, unstable quality, low production efficiency, and high production costs. When using mechanical assisted winding, due to restrictions such as usage conditions and operating modes, the winding tension cannot be effectively controlled, and the instantaneous kinetic energy impact of winding directly acts on the enameled wire, magnetic core and magnetic core shell, causing damage, resulting in a high product defect rate.

[0004] For example, the publication number "CN117912836A" discloses "an inductor coil winding device for electronic equipment", including a machine tool plate; it also includes: a support plate, the support plate is installed on the machine tool plate, a circular through hole is opened on the support plate, and a notch is provided on the circular through hole; an annular baffle plate, the annular baffle plate is installed on the top of the support plate, the center of the annular baffle plate and the center of the circular through hole on the support plate are located on the same vertical line, and a notch is also provided on the annular baffle plate, which is in the same direction as the notch of the circular through hole on the support plate; a lower pull hook, the lower pull hook can be installed on the working plane in a lifting manner; an upper lifting mechanism, the upper lifting mechanism includes an upper lifting clamp, and the upper lifting clamp can be rotatably installed on the machine tool plate. However, in actual applications, such devices will produce impacts at the moment of starting and stopping, which will cause instantaneous dynamic impact damage to the magnetic core, the magnetic core shell and the enameled wire, and the quality and reliability cannot be guaranteed.

[0034] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1:

[0036] like Figure 1 , 2 As shown, a winding device for a hydraulic transmission toroidal inductor includes a base 1, a guide rail 2 is arranged on the base 1, a clamping seat 3 is slidably connected to the guide rail 2, the clamping seat 3 is connected to a driving rod 4, an auxiliary baffle 5 is connected to the driving rod 4, and an energy absorbing spring group 6 is arranged between the auxiliary baffle 5 and the clamping seat 3. A positioning rod 11 is connected to the side of the clamping seat 3 close to the driving rod 4, and the auxiliary baffle 5 is slidably connected to the positioning rod 11.

[0037] By setting the energy-absorbing spring group 6, a buffering effect can be generated between the auxiliary baffle 5 and the clamping seat 3. At the start and stop moments of the clamping seat 3 moving forward and backward, the energy-absorbing spring group 6 can be used for buffering, thereby effectively reducing the dynamic impact at the start and stop moments during winding, effectively protecting the magnetic core, the magnetic core shell and the enameled wire from instantaneous dynamic impact damage, and effectively improving the product quality and reliability. In the present application, the guide rail 2 is slidably connected to the clamping seat 3 to ensure the linear motion of the clamping seat 3, and the driving rod 4 can be connected to a driving mechanism, such as various cylinder drives, hydraulic drives, etc., and a driving force can be generated on the clamping seat 3 through the driving rod 4. The energy-absorbing spring group 6 is set between the auxiliary baffle 5 and the clamping seat 3, thereby avoiding the start and stop actions on the driving rod 4 from being directly transmitted to the clamping seat 3, reducing the kinetic energy impact; through the sliding connection between the positioning rod 11 and the auxiliary baffle 5, a guiding effect can be provided for the auxiliary baffle 5 to ensure the stable forward and backward movement of the auxiliary baffle 5, wherein the movement close to the side of the toroidal inductor is forward movement, and the movement away from the side of the toroidal inductor is backward movement.

[0038] like Figure 2 As shown, the driving rod 4 is provided with a top block 41, which is arranged on the side of the auxiliary baffle 5 away from the clamping seat 3, and the energy absorption spring group 6 includes a forward energy absorption spring 61, which is sleeved on the positioning rod 11, and the forward energy absorption spring 61 abuts the auxiliary baffle 5. The driving rod 4 is sleeved with a backward energy absorption spring 62 on the side of the auxiliary baffle 5 close to the clamping seat 3. The driving rod 4 is provided with a pressure block 42, which is arranged on the side of the backward energy absorption spring 62 close to the clamping seat 3, and the pressure block 42 abuts the backward energy absorption spring 62.

[0039] The energy absorption spring group 6 includes a forward energy absorption spring 61, wherein the forward energy absorption spring 61 is sleeved on the positioning rod 11, so the forward energy absorption spring 61 is clamped between the clamping seat 3 and the auxiliary baffle 5, reducing the impact force in the process of switching from stop to advance and from retreat to stop. When the driving rod 4 drives the top block 41 to move, the auxiliary baffle 5 is squeezed by the top block 41, thereby generating an extrusion force on the forward energy absorption spring 61; the backward energy absorption spring 62 is arranged on the driving rod 4 and sleeved with the driving rod 4, and the backward energy absorption spring 62 is arranged on the side of the auxiliary baffle 5 close to the clamping seat 3, so that the backward energy absorption spring 62 can be compressed in the process of switching from stationary to retreat and from forward to stop, thereby achieving a buffering effect; the pressure block 42 arranged on the driving rod 4 is arranged at one end of the driving rod 4 close to the clamping seat 3, so the backward energy absorption spring 62 is arranged between the pressure block 42 and the auxiliary baffle 5, thereby achieving an extrusion effect on the backward energy absorption spring 62.

[0040] like Figure 3As shown, a pressure regulating assembly 8 is provided on the base 1, and the pressure regulating assembly 8 includes a pressure regulating valve 81, and a pressure regulating gauge 82 is connected to the pressure regulating valve 81. The pressure regulating assembly 8 can quickly adjust the hydraulic value of the driving rod 4, control the distance and speed, and improve the adaptability to different production scenarios.

[0041] like Figure 1 As shown, a distribution box 9 is arranged on the side of the base 1.

[0042] The assembly and working process of the winding device of the hydraulic transmission toroidal inductor in this embodiment are as follows: in this embodiment, a base 1 is provided, and a guide rail 2 is provided on the base 1, wherein two guide rails 2 are provided in this embodiment, and a wire clamping seat 3 is slidably connected to the guide rail 2, and the components provided on the wire clamping seat 3 can realize the clamping of the winding, wherein the wire clamping seat 3 is connected to the driving rod 4, and the driving rod 4 can drive the wire clamping seat 3 to slide back and forth on the guide rail 2, and an auxiliary baffle 5 is connected to the driving rod 4, wherein an energy absorption spring group 6 is provided between the auxiliary baffle 5 and the wire clamping seat 3, in this embodiment, the energy absorption spring group 6 includes a forward energy absorption spring 61 and a backward energy absorption spring 62, the driving rod 4 passes through the auxiliary baffle 5, and a top block 41 is connected to the driving rod 4, wherein the top block 41 is arranged on the side of the auxiliary baffle 5 away from the wire clamping seat 3, and when the driving rod 4 is pushed to the right as shown in the figure, the top block 41 abuts against the auxiliary baffle 5. The auxiliary baffle 5 transmits the rightward movement of the driving rod 4, driving the auxiliary baffle 5 to move rightward synchronously. In this embodiment, a positioning rod 11 is provided on the side of the clamping seat 3 close to the driving rod 4. Two positioning rods 11 are provided, and forward energy absorption springs 61 are provided on the two positioning rods 11. In this embodiment, the positioning rod 11 is provided with a step surface, so the two ends of the forward energy absorption spring 61 are respectively abutted on the auxiliary baffle 5 and the step surface. When the auxiliary baffle 5 moves to the right, since the clamping seat 3 is in a stationary state, it is necessary to transmit the force through the forward energy absorption spring 61 provided therebetween. During the transmission process, the forward energy absorption spring 61 can partially buffer, so that the clamping seat 3 will not start suddenly, which can effectively reduce the instantaneous dynamic impact of starting and stopping during winding, effectively protect the magnetic core, the magnetic core shell and the enameled wire from instantaneous dynamic impact damage, and effectively improve the production quality and reliability.

[0043] In addition to the above-mentioned forward energy absorption spring 61, a backward energy absorption spring 62 is also provided in the present application, wherein the backward energy absorption spring 62 is arranged on the driving rod 4, and a pressure block 42 is arranged at the end of the driving rod 4 close to the clamping seat 3, and the backward energy absorption spring 62 is arranged between the pressure block 42 and the auxiliary baffle 5. When the driving rod 4 drives the clamping seat 3 to move to the left, the top block 41 is arranged on the left side of the auxiliary baffle 5, and therefore will not move synchronously with the auxiliary baffle 5. The top block 41, the driving rod 4, and the pressure block 42 move synchronously. At this time, the auxiliary baffle 5, the positioning rod 11, the clamping seat 3, and the energy absorption spring group 6 remain stationary. Therefore, when the pressure block 42 needs to transmit force through the backward energy absorption spring 62, it will produce a buffering effect through the backward energy absorption spring 62, and then drive the entire clamping seat 3 to move to the left.

[0044] In addition to the above two situations, the forward energy absorption spring 61 and the backward energy absorption spring 62 provided in the present embodiment can realize the buffering effect during the sudden stop process. When the driving rod 4 drives the wire clamping seat 3 to move to the right, when the driving rod 4 is transformed from the moving state to the stopped state, the wire clamping seat 3 is affected by inertia and will continue to maintain the tendency to move to the right. At this time, since the driving rod 4 has stopped, the wire clamping seat 3 drives the auxiliary baffle 5 to squeeze the backward energy absorption spring 62 to achieve the buffering effect; on the contrary, when the driving rod 4 moves to the left, it is transformed from the moving state to the stopped state. At this time, the wire clamping seat 3 maintains the tendency to move to the left. Therefore, the wire clamping seat 3 drives the positioning rod 11 to move, and the step surface on the positioning rod 11 squeezes the forward energy absorption spring 61. When the step surface is not provided on the positioning rod 11, the buffering effect is achieved by the wire clamping seat 3 directly abutting against the forward energy absorption spring 61.
