Description

Technical Field

[0001] This application relates to the field of magnet winding production equipment, and more particularly to equipment for magnet winding. Background Technology

[0002] A magnet winding is a component made by winding a coil around a magnet. This structure is widely used in energy conversion, signal processing and other fields. With the development of electroacoustic equipment and sensor systems, the shapes of magnet windings have gradually become more diverse.

[0003] Existing magnet winding production equipment includes a machine tool and a fixture. The spindle of the machine tool is connected to the fixture, which is set horizontally and holds the magnet. The machine tool drives the magnet to rotate through the fixture. The user fixes the end of the metal cable to the magnet, causing the magnet to rotate and wind the cable, thus achieving the effect of producing magnet windings.

[0004] The aforementioned technical solutions have the following drawbacks: when the magnet is irregularly shaped, it is difficult to install the magnet on the machine tool, and a fixture that matches the shape of the magnet needs to be customized. Utility Model Content

[0005] To facilitate clamping and fixing irregularly shaped magnets and winding coils, this application provides a device for winding magnets.

[0006] The device for winding magnets provided in this application adopts the following technical solution: A device for winding magnets includes a machine tool, a fixture, and a fixing mechanism. The spindle of the machine tool is connected to the fixture, which is a three-jaw chuck. The fixing mechanism includes an end plate 1, an end plate 2, and multiple connecting rods. One end of each connecting rod is detachably connected to the end plate 1, and the other end is detachably connected to the end plate 2. The end plates 1 and 2 are used to clamp the magnets.

[0007] By adopting the above technical solution, a fixture is set on the machine tool, allowing the magnet to be installed on the fixed mechanism. The fixture clamps the fixed mechanism, thereby enabling the machine tool to drive the magnet to rotate. By connecting the two ends of the connecting rod to end plate one and end plate two respectively, the user can insert the connecting rod into the cavity in the middle of the magnet, so that end plate one and end plate two together clamp the magnet. When the fixture clamps the fixed mechanism, the magnet can maintain a stable position between end plate one and end plate two, which facilitates the fixture to clamp and fix irregularly shaped magnets and wind coils.

[0008] Optionally, the first end plate and the second end plate are circular plates. The first end plate has multiple sliding grooves 1 spaced at equal intervals along the circumference, and the second end plate has multiple sliding grooves 2 spaced at equal intervals along the circumference. One end of the connecting rod is slidably connected in the first sliding groove, and the other end is slidably connected in the second sliding groove.

[0009] By adopting the above technical solution, by opening grooves on end plate one and end plate two, the connecting rod can be inserted into the grooves and slide in the grooves. The connecting rod remains perpendicular to end plate one and end plate two. When the connecting rod is inserted into the cavity in the middle of the magnet, the connecting rod can abut against the inner wall of the magnet, thereby making the magnet maintain a stable position in end plate one and end plate two.

[0010] Optionally, nuts are threaded onto both ends of the connecting rod.

[0011] By adopting the above technical solution, nuts are set at both ends of the connecting rod so that the nuts can abut against end plate one or end plate two. When a magnet is set between end plate one and end plate two, the nuts cause end plate one and end plate two to clamp the magnet together, thereby reducing the probability of the magnet slipping between end plate one and end plate two.

[0012] Optionally, a clamping block is installed on the end plate, and the clamp is used to hold the clamping block.

[0013] By adopting the above technical solution, by setting a clamping block on the first end plate, the clamping device can hold the clamping block, thereby enabling the first end plate to be stably attached to the clamping device.

[0014] Optionally, the clamping block has a cylindrical structure, and the clamping block and the end plate are coaxially arranged.

[0015] By adopting the above technical solution and setting the clamping block and the end plate coaxially, the user can install the cylindrical magnet in the fixing mechanism, which makes it convenient for the user to wind coils on magnets of different shapes.

[0016] Optionally, a handle is provided on end plate one, and a handle is provided on end plate two.

[0017] By adopting the above technical solution, and by setting handle one on end plate one and handle two on end plate two, the user can move and transport the magnet by using handle one and handle two, which is convenient for use.

[0018] Optionally, a spring is provided between the first end plate and the second end plate, with one end of the spring abutting against the first end plate and the other end abutting against the second end plate.

[0019] By adopting the above technical solution, a spring is set between end plate one and end plate two, with one end of the spring abutting against end plate one and the other end abutting against end plate two. When end plate one and end plate two clamp the magnet together, the spring contracts and abuts against end plate one and end plate two, thereby reducing the probability of the nut falling off the connecting rod.

[0020] Optionally, end plates one and two are provided with retaining sleeves, and the end of the spring is inserted into the retaining sleeve.

[0021] By adopting the above technical solution, by setting a retainer on end plate one and end plate two, the end of the spring can be locked in the retainer, thereby reducing the probability of the spring slipping between end plate one and end plate two.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By setting a fixture on the machine tool, the magnet can be installed on the fixed mechanism. The fixture clamps the fixed mechanism, thereby enabling the machine tool to drive the magnet to rotate. By connecting the two ends of the connecting rod to end plate one and end plate two respectively, the user can insert the connecting rod into the cavity in the middle of the magnet, so that end plate one and end plate two clamp the magnet together. When the fixture clamps the fixed mechanism, the magnet can maintain a stable position between end plate one and end plate two, which facilitates the fixture to clamp and fix irregularly shaped magnets and wind coils. 2. By opening grooves on end plate one and end plate two, the connecting rod can be inserted into the groove and slide in the groove. The connecting rod remains perpendicular to end plate one and end plate two. When the connecting rod is inserted into the middle cavity of the magnet, the connecting rod can abut against the inner wall of the magnet, thereby making the magnet maintain a stable position in end plate one and end plate two. 3. By setting handle one on end plate one and handle two on end plate two, the user can move and transport the magnet by using handle one and handle two, which is convenient for use.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a device for winding magnets, referring to... Figure 1The system includes a machine tool 1, a fixture 2, and a fixing mechanism 3. The fixture 2 is mounted on the machine tool 1, and the drive shaft of the machine tool 1 is horizontally positioned and connected to the fixture 2. The fixing mechanism 3 is used to mount the workpiece. By placing an irregularly shaped workpiece on the fixing mechanism 3, the user can cause the fixture 2 to clamp the fixing mechanism 3, enabling the machine tool 1 to drive the workpiece to rotate, thereby allowing the metal wire to be wound around the workpiece, completing the magnet winding production process.

[0029] Reference Figure 2 and Figure 3 The clamp 2 is configured as a three-jaw chuck. The fixing mechanism 3 includes end plate 1 31, end plate 2 32, and multiple connecting rods 33. End plate 1 31 and end plate 2 32 are circular plates and are parallel to each other. Multiple connecting rods 33 are arranged between end plate 1 31 and end plate 2 32, with one end of each connecting rod connected to end plate 1 31 and the other end connected to end plate 2 32. Multiple connecting rods 33 are inserted into the central cavity of the workpiece, and end plate 1 31 and end plate 2 32 abut against both sides of the workpiece.

[0030] Reference Figure 2 and Figure 3 Multiple sliding grooves 311 are provided on end plate 31, and these grooves are equidistantly spaced along the circumference of end plate 31. Multiple sliding grooves 321 are provided on end plate 32, and these grooves are equidistantly spaced along the circumference of end plate 32. A connecting rod 33 is inserted into the sliding grooves 311 and 321. The connecting rod 33 can slide within the sliding grooves 311 and 321, thereby securing the connecting rod 33 to the inner wall of the cylindrical workpiece. A thread is provided at the end of the connecting rod 33, and nuts 331 are threaded to both ends of the connecting rod 33. The nuts 331 are used to secure the workpiece to the end face of end plate 31 or end plate 32, thereby maintaining a stable position between end plate 31 and end plate 32.

[0031] Reference Figure 3 A clamping block 312 is connected to one end face of the end plate 31. The clamping block 312 is a cylindrical structure and is coaxially connected to the end plate 31. The fixture 2 can install the fixing mechanism 3 on the fixture 2 by clamping the clamping block 312. When the cylindrical workpiece is installed on the fixing mechanism 3, the workpiece can be coaxially installed on the end plate 31 and wound with coil.

[0032] Reference Figure 2 and Figure 3 A handle 313 is fixed on end plate 31, and a handle 322 is fixed on end plate 32. When connecting rod 33 connects end plate 31 and end plate 32, handle 313 is located on the side of end plate 31 away from end plate 32, and handle 322 is located on the end of end plate 32 away from end plate 31. The fixed mechanism 3 and the workpiece can be easily moved by handle 313 and handle 322.

[0033] Reference Figure 2 and Figure 3 A spring 34 is provided between end plate 31 and end plate 32. The spring 34 abuts against end plate 31 and end plate 32. When the connecting rod 33 connects end plate 31 and end plate 32, the spring 34 contracts and applies a spring force to end plate 31 and end plate 32. The spring 34 can provide support for end plate 31 and end plate 32, so that end plate 31 and end plate 32 abut against nut 331, reducing the probability of nut 331 slipping on connecting rod 33.

[0034] Reference Figure 3 A retaining sleeve 341 is coaxially fixed on end plate 31 and end plate 32 respectively. The retaining sleeve 341 is coaxially arranged with end plate 31 or end plate 32. The end of spring 34 is arranged in retaining sleeve 341. Retaining sleeve 341 serves to fix the end of spring 34, so that the length direction of spring 34 is parallel to the length direction of connecting rod 33.

[0035] The implementation principle of this application embodiment is as follows: By setting multiple connecting rods 33 between end plate 1 31 and end plate 2 32, the two ends of the connecting rods 33 slide in slide groove 1 311 and slide groove 2 321 respectively, thereby enabling the connecting rods 33 to be locked on the inner wall of the hollow cavity of the workpiece, so that the workpiece remains in a stable position. By setting handle 1 313 on end plate 1 31 and handle 2 322 on end plate 2 32, it is convenient for the user to move the fixing mechanism 3 and the workpiece through handle 1 313 and handle 2 322.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
