Description

Technical Field

[0001] This invention belongs to the field of inductor winding tooling technology, and specifically relates to an inductor winding tooling. Background Technology

[0002] A wire-wound inductor is a passive electronic component used to store and release magnetic energy. It consists of a coil of wire wound into a spiral shape with one or more turns. The manufacturing process of an inductor includes winding, soldering, and shaping, with winding being a crucial step in the manufacturing process.

[0003] There are generally two ways to wind inductors: one is to purchase a winding machine, but traditional winding machines are expensive and not cost-effective; the other is to customize online, but the customization cycle is relatively long and the price is not cost-effective when the quantity is small. Summary of the Invention

[0004] This invention provides an inductor winding fixture, which aims to solve the problem that there are generally two ways to wind inductors: one is to purchase a winding machine, but traditional winding machines are expensive and not cost-effective; the other is to customize online, but the customization cycle is relatively long and the price is not cost-effective when the quantity is small.

[0005] This invention provides an inductor winding fixture, including a base, a bearing seat fixedly connected to the upper end of the base, a wire clamping shaft disposed on the bearing seat, the bearing seat and the wire clamping shaft being rotatably connected via a bearing component, an inductor winding needle disposed at one end of the wire clamping shaft, the wire clamping shaft and the inductor winding needle being connected via a locking nut, a rotating plate fixedly connected to the other end of the wire clamping shaft, two rotating heads symmetrically fixedly connected to the rotating plate, a thin copper wire wound on the inductor winding needle, a self-maintenance component disposed inside the bearing seat and above the bearing component, and a recycling component disposed inside the bearing seat and below the bearing component.

[0006] By adopting the above technical solution, during operation, the inductor winding needle is inserted into the tapered opening of the clamping shaft, the locking nut is screwed into the clamping shaft to lock the inductor winding needle, and then the copper wire on the base is wound around the inductor winding needle by the rotation of the clamping shaft to complete the inductor production. During the winding process, the self-maintenance component maintains the bearing components by itself, ensuring the smooth rotation of the clamping shaft and the service life of the device. At the same time, the recycling component can recover excess oil and press it back into the self-maintenance component for reuse, saving resources. The entire device has a simple structure, low cost, easy operation and maintenance, and is easy to customize and has high production efficiency.

[0007] Furthermore, the end of the clamping shaft away from the bearing seat is tapered, and a cross-shaped cut is provided at its end.

[0008] By adopting the above technical solution, the inductor winding needle can be clamped, making it convenient to wind miniature inductors.

[0009] Furthermore, the bearing component includes an outer ring disposed in the bearing housing and an inner ring disposed outside the clamping shaft. A bracket is provided between the outer ring and the inner ring, and a steel ball is rotatably disposed on the bracket. One side of the steel ball is embedded in the outer wall of the inner ring, and the steel ball can roll on the wall surfaces of the outer ring and the inner ring. Sealing rings are provided on both sides between the outer ring and the inner ring.

[0010] By adopting the above technical solution, the rotational connection between the clamping shaft and the bearing housing is realized, and the sealing of the cavity between the outer ring and the inner ring is ensured.

[0011] Furthermore, the self-maintenance component includes a guide hole formed at the top of the outer ring and a storage chamber and an injection hole formed in the bearing seat. The guide hole is arc-shaped, with its upper end connected to the bottom of the storage chamber and its lower end open and connected to the cavity between the outer and inner rings. The injection hole's lower end is connected to the top of the storage chamber. The storage chamber is filled with organic oil. The upper end of the injection hole extends out of the bearing seat. A sealing unit is provided at the opening of the guide hole, and the sealing unit can be opened by the steel ball.

[0012] By adopting the above technical solution, when the steel ball rotates to the sealing unit, the steel ball causes the sealing unit to move and opens the lower end of the guide hole, allowing the oil in the storage chamber to flow into the cavity between the outer ring and the inner ring. At the same time, the steel ball comes into contact with the oil to achieve the purpose of automatic maintenance. When the steel ball moves away from the sealing unit, the sealing unit moves and closes the lower end of the guide hole again to prevent the oil from flowing out continuously, which would cause the bearing components to malfunction due to excessive oil.

[0013] Furthermore, the sealing unit includes a telescopic rod fixedly connected to the upper wall of the storage chamber. A return spring is sleeved on the outer side of the telescopic rod. A support block is fixedly connected to the lower end of the telescopic rod. The two ends of the return spring are respectively connected to the support block and the upper wall of the storage chamber. A leak-proof ball is provided at the lower end of the support block. The leak-proof ball is pressed against the lower opening of the guide hole under the action of the return spring. The bottom of the leak-proof ball extends out of the lower opening of the guide hole and contacts the steel ball.

[0014] By adopting the above technical solution, when the steel ball rotates to the sealing unit, the steel ball pushes the anti-leak ball, the return spring is compressed, and the telescopic rod retracts. At this time, the anti-leak ball opens the lower end of the guide hole, allowing the oil in the storage chamber to enter the cavity between the outer ring and the inner ring, thereby realizing automatic maintenance of the bearing components and improving the smoothness and service life of the device. When the steel ball moves away from the anti-leak ball, under the deformation force of the return spring, the anti-leak ball is pressed tightly against the lower end of the guide hole, thereby blocking the lower end of the guide hole and preventing excessive oil from flowing into the bearing components.

[0015] Furthermore, the recycling assembly includes a collection chamber and a guide channel formed in the bearing housing. The guide channel is funnel-shaped, and its upper end is connected to the cavity between the outer and inner rings through a flow hole. One side of the lower end of the collection chamber is connected to the upper end of the storage chamber through a channel. The middle of the upper end of the collection chamber is connected to the middle of the lower end of the guide channel. A piston is slidably installed in the collection chamber, dividing the collection chamber into a left cavity and a right cavity. The lower end of the piston has a through-flow channel. The guide hole is equipped with a one-way valve, through which the oil in the right cavity can flow to the left cavity. A piston rod is provided at the right end of the piston, with the end of the piston rod away from the piston extending out of the bearing seat. An inclined surface is provided at the end of the piston rod away from the piston. A second return spring is sleeved on the outside of the piston rod, with both ends of the second return spring connected to the right wall of the piston and the right wall of the collection chamber, respectively. When the rotating plate rotates, it contacts and presses the inclined surface, causing the piston rod to move into the collection chamber.

[0016] By adopting the above technical solution, excess oil flows downwards under its own gravity to the flow hole, then flows into the guide channel, and finally into the collection chamber. When the device is winding, the rotating plate rotates and compresses the inclined plane, causing the piston rod to move towards the collection chamber. The return spring extends, and the piston rod pushes the piston to move in the collection chamber. The piston compresses the oil in the collection chamber and returns it to the storage chamber for continued use through the channel, avoiding waste of oil. When the piston moves to the left, the guide channel connects with the right cavity. At this time, as the piston continues to move, it can draw oil from the guide channel and drop it into the collection chamber, thereby drawing excess oil from the cavity between the outer and inner rings. When the rotating plate leaves the piston rod, the piston slowly returns to its original position under the deformation force of the return spring. During the piston's return process, the piston compresses the oil in the right cavity and delivers it to the left cavity through the guide hole, ensuring that excess oil can return to the storage chamber for continued use.

[0017] The beneficial effects of this invention are as follows:

[0018] In operation, the inductor winding needle is inserted into the tapered opening of the clamping shaft, and the locking nut is screwed into the clamping shaft to lock the inductor winding needle. Then, the copper wire on the base is wound around the inductor winding needle by the rotation of the clamping shaft, thus completing the inductor fabrication. During the winding process, the self-maintenance component maintains the bearing components, ensuring the smooth rotation of the clamping shaft and extending the service life of the device. At the same time, the recycling component can recover excess oil and press it back into the self-maintenance component for reuse, saving resources. The entire device has a simple structure, low cost, easy operation and maintenance, and is easy to customize and has high production efficiency.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Reference Figures 1-6 This invention provides an inductor winding fixture, comprising a base 1, a bearing seat 2 fixedly connected to the upper end of the base 1, a wire clamping shaft 4 disposed on the bearing seat 2, the bearing seat 2 and the wire clamping shaft 4 being rotatably connected via a bearing component 3, an inductor winding needle 8 disposed at one end of the wire clamping shaft 4, the wire clamping shaft 4 and the inductor winding needle 8 being connected via a locking nut 5, a rotating plate 6 fixedly connected to the other end of the wire clamping shaft 4, two rotating heads 7 being symmetrically fixedly connected on the rotating plate 6, a thin copper wire 9 being wound on the inductor winding needle 8, a self-maintenance component 10 disposed inside the bearing seat 2 and above the bearing component 3, and a recycling component 11 disposed inside the bearing seat 2 and below the bearing component 3.

[0030] During operation, the inductor winding needle 8 is inserted into the tapered opening of the clamping shaft 4, and the locking nut 5 is screwed into the clamping shaft 4 to lock the inductor winding needle 8. Then, the copper wire on the base 1 is wound around the inductor winding needle 8 by the rotation of the clamping shaft 4 to complete the inductor production. During the winding process, the self-maintenance component 10 maintains the bearing component 3 itself to ensure the smooth rotation of the clamping shaft 4 and the service life of the device. At the same time, the recycling component 11 can recover excess oil and press it back into the self-maintenance component 10 for reuse, saving resources. The entire device has a simple structure, low cost, easy operation and maintenance, and is easy to customize and has high production efficiency.

[0031] Reference Figure 2 and Figure 3 The end of the clamping shaft 4 away from the bearing seat 2 is tapered, and a cross cut is provided at its end to clamp the inductor winding needle 8, which is convenient for winding miniature inductors.

[0032] Reference Figure 3 and Figure 4 The bearing component 3 includes an outer ring 31 disposed in the bearing housing 2 and an inner ring 32 disposed outside the clamping shaft 4. A bracket 33 is disposed between the outer ring 31 and the inner ring 32. A steel ball 34 is rotatably disposed on the bracket 33. One side of the steel ball 34 is embedded in the outer wall of the inner ring 32. The steel ball 34 can roll on the wall surfaces of the outer ring 31 and the inner ring 32. Sealing rings 35 are disposed on both sides between the outer ring 31 and the inner ring 32, realizing the rotational connection between the clamping shaft 4 and the bearing housing 2, and ensuring the sealing of the cavity between the outer ring 31 and the inner ring 32.

[0033] Reference Figure 3 and Figure 4 The self-maintenance component 10 includes a guide hole 101 opened on the top of the outer ring 31, a storage chamber 102 and an injection hole 103 opened in the bearing seat 2. The guide hole 101 is arc-shaped, and the upper end of the guide hole 101 is connected to the bottom of the storage chamber 102. The lower end of the guide hole 101 is open and connected to the cavity between the outer ring 31 and the inner ring 32. The lower end of the injection hole 103 is connected to the top of the storage chamber 102. The storage chamber 102 is filled with organic oil. The upper end of the injection hole 103 extends out of the bearing seat 2. A sealing unit is provided at the opening of the guide hole 101. The sealing unit can be opened by the steel ball 34.

[0034] When the steel ball 34 rotates to the sealing unit, it causes the sealing unit to move and opens the lower end of the guide hole 101, allowing the oil in the storage chamber 102 to flow into the cavity between the outer ring 31 and the inner ring 32. At the same time, the steel ball 34 comes into contact with the oil to achieve automatic maintenance. When the steel ball 34 moves away from the sealing unit, the sealing unit moves and closes the lower end of the guide hole 101 again to prevent the oil from flowing out continuously and causing the bearing component 3 to malfunction due to excessive oil.

[0035] Reference Figure 4 The sealing unit includes a telescopic rod 105 fixedly connected to the upper wall of the storage chamber 102. A return spring 104 is sleeved on the outer side of the telescopic rod 105. A support block 106 is fixedly connected to the lower end of the telescopic rod 105. The two ends of the return spring 104 are respectively connected to the support block 106 and the upper wall of the storage chamber 102. A leak-proof ball 107 is provided at the lower end of the support block 106. Under the action of the return spring 104, the leak-proof ball 107 is pressed against the lower opening of the guide hole 101. The bottom of the leak-proof ball 107 extends out of the lower opening of the guide hole 101 and contacts the steel ball 34.

[0036] When the steel ball 34 rotates to the sealing unit, it pushes the anti-leak ball 107, compresses the return spring 104, and retracts the telescopic rod 105. At this time, the anti-leak ball 107 opens the lower end of the guide hole 101, allowing the oil in the storage chamber 102 to enter the cavity between the outer ring 31 and the inner ring 32, thereby achieving automatic maintenance of the bearing component 3 and improving the smoothness and service life of the device. When the steel ball 34 moves away from the anti-leak ball 107, under the deformation force of the return spring 104, the anti-leak ball 107 is pressed against the lower end of the guide hole 101, thereby blocking the lower end of the guide hole 101 and preventing excessive oil from flowing into the bearing component 3.

[0037] Reference Figure 3 , Figure 5 and Figure 6The recycling assembly 11 includes a collection chamber 111 and a guide channel 112 formed in the bearing housing 2. The guide channel 112 is funnel-shaped. The upper end of the guide channel 112 is connected to the cavity between the outer ring 31 and the inner ring 32 through a flow hole 113. One side of the lower end of the collection chamber 111 is connected to the upper end of the storage chamber 102 through a channel 114. The middle of the upper end of the collection chamber 111 is connected to the middle of the lower end of the guide channel 112. A piston 115 is slidably installed in the collection chamber 111, dividing the collection chamber 111 into a left cavity and a right cavity. The lower end of the piston 115 has a through hole 116 that extends from left to right. A one-way valve is provided in the through hole 116, through which the oil in the right chamber can flow to the left chamber. A piston rod 117 is provided at the right end of the piston 115. The end of the piston rod 117 away from the piston 115 extends out of the bearing seat 2. An inclined surface 118 is provided at the end of the piston rod 117 away from the piston 115. A return spring 119 is sleeved on the outside of the piston rod 117. The two ends of the return spring 119 are connected to the right wall of the piston 115 and the right wall of the collection chamber 111, respectively. When the rotating plate 6 rotates, it contacts and presses the inclined surface 118, causing the piston rod 117 to move into the collection chamber 111.

[0038] Excess oil flows downwards under its own weight to the flow hole 113, then through the flow hole 113 into the guide groove 112, and then from the guide groove 112 into the collection chamber 111 for collection. When the device is winding, the rotating plate 6 rotates and compresses the inclined plane 118, causing the piston rod 117 to move towards the collection chamber 111. The return spring 119 extends, and the piston rod 117 pushes the piston 115 to move in the collection chamber 111. The piston 115 squeezes the oil in the collection chamber 111 and returns it to the storage chamber 102 through the channel 114 for continued use, avoiding waste of oil. When piston 115 moves to the left, guide channel 112 connects with the right cavity. At this time, as piston 115 continues to move, it can draw oil from guide channel 112 and drop it into collection chamber 111. It can also draw excess oil from the cavity between outer ring 31 and inner ring 32. When rotating plate 6 leaves piston rod 117, piston 115 slowly returns to its original position under the deformation force of return spring 119. During the return process of piston 115, piston 115 squeezes the oil in right cavity and delivers it to left cavity through guide hole 116, ensuring that excess oil can return to storage chamber 102 for continued use.
