Description

Technical Field

[0001] This utility model relates to the field of electronic coil winding fixing technology, and in particular to a stator coil frame fixing device. Background Technology

[0002] Electric motors, as key electromagnetic devices that convert or transmit electrical energy based on the law of electromagnetic induction, occupy a crucial position in modern industry and daily life. The stator coil is an indispensable and vital component of the motor. Only by using specialized winding machines and following precise process requirements can the coils mounted on the stator coil frame ensure the motor's efficient and stable operation.

[0003] Chinese Patent (Application No.: CN201922305650.8) discloses "A coil frame fixing device for a stator coil winding machine". Through the design of a rotating platform, when the winding machine is winding the coil frame on a fixed rod on one side of the rotating platform, the worker can install and fix the coil frame to be wound on the fixed rod on the other side. When the winding on one side is completed, the rotating platform only needs to be rotated 180° to exchange the position of the coil frame that has been wound and the coil frame to be wound. This solves the problem that after the winding machine has finished winding the previous set of coil frames, it is necessary to stop the machine to remove the wound coil frame before a new coil frame can be installed, which leads to long downtime and affects the winding speed.

[0004] However, the diameter of the fixing rod used to fix the coil frame cannot be adjusted according to the diameter of the coil frame. Therefore, whenever the coil frame of a motor of different specifications is fixed, the original fixing rod cannot be adapted due to the size difference. The staff has to replace it with a matching fixing rod, which not only reduces the overall speed of coil frame winding, but also increases the complexity and inconvenience of operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stator coil holder fixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stator coil holder fixing device includes a mounting frame, a rotating assembly at the bottom of the mounting frame, a mounting plate mounted on the mounting frame via the rotating assembly, a fixing plate fixedly mounted on the top of the mounting plate, a screw rotatably mounted inside the mounting plate, the screw and the fixing plate being rotatably connected, a threaded sleeve being threaded on the surface of the screw, a first connecting plate being fixedly mounted on the surface of the threaded sleeve, a connecting rod rotatably mounted on the surface of the first connecting plate, a second connecting plate rotatably mounted on the surface of the connecting rod, a support block being fixedly mounted on the surface of the second connecting plate, a limit block being fixedly mounted at the bottom of the support block, a limit groove being formed on the surface of the fixing plate, the limit block and the limit groove being slidably connected, and a driving assembly at the bottom of the mounting plate.

[0008] Preferably, the rotating assembly includes a motor fixedly mounted at the bottom of the mounting frame, the output end of the motor extending through the mounting frame into the interior of the mounting frame and fixedly mounted with a rotating shaft, and the rotating shaft being fixedly connected to the mounting plate.

[0009] Preferably, the drive assembly includes a drive shaft rotatably disposed at the bottom of the mounting plate, a drive pulley fixedly disposed on the surface of the drive shaft, a timing belt meshing with the surface of the drive pulley, a driven pulley meshing with the inside of the timing belt, and the driven pulley and the screw fixedly connected.

[0010] Preferably, a knob is fixedly provided at the bottom end of the drive shaft, and the knob is located at the bottom edge of the mounting plate.

[0011] Preferably, there are multiple support blocks, and all of the support blocks are made of non-slip rubber.

[0012] Preferably, there are multiple connecting rods, and the multiple connecting rods are symmetrically distributed on the surface of the first connecting plate.

[0013] Preferably, there are two fixing plates, and the two fixing plates are symmetrically distributed on the top of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The stator coil frame fixing device uses a drive assembly to rotate the screw, which in turn drives the threaded sleeve to move linearly. The downward movement of the threaded sleeve pushes the support block to move through the first connecting plate, the connecting rod, and the second connecting plate. The support block drives the limiting block to slide outward inside the limiting groove. By using multiple support blocks to abut against the inner side of the coil frame, coil frames of different diameters can be fixed.

This avoids the need for workers to replace different fixing rods for different specifications of coil frames, thus improving the practicality and convenience of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5A stator coil holder fixing device includes a mounting frame 1. A rotating assembly is provided at the bottom of the mounting frame 1. A mounting plate 4 is mounted on the mounting frame 1 via the rotating assembly. Two fixing plates 5 are fixedly mounted on the top of the mounting plate 4, symmetrically distributed. The two fixing plates 5 are used to mount two sets of support blocks 11. A screw 6 is rotatably mounted inside the mounting plate 4, rotatably connected to the fixing plate 5. A threaded sleeve 7 is threaded onto the surface of the screw 6. A first connecting plate 8 is fixedly mounted on the surface of the threaded sleeve 7. Multiple connecting rods 9 are rotatably mounted on the surface of the first connecting plate 8, symmetrically distributed. The multiple connecting rods 9 improve the stability of the support blocks 11 movement. A second connecting plate 10 is rotatably mounted on the surface of the connecting rods 9. Multiple support blocks 11 are fixedly mounted on the surface of the second connecting plate 10, all made of anti-slip rubber. The anti-slip rubber support block 11 effectively prevents the coil frame from sliding on its surface. The anti-slip rubber deforms upon contact with the coil frame, thus protecting it. A limiting block 13 is fixedly installed at the bottom of the support block 11, and a limiting groove 12 is formed on the surface of the fixing plate 5. The limiting block 13 and the limiting groove 12 are slidably connected. A drive assembly is provided at the bottom of the mounting plate 4. This stator coil frame fixing device uses the drive assembly to rotate the screw 6. The rotation of the screw 6 drives the threaded sleeve 7 to move linearly. The downward movement of the threaded sleeve 7 pushes the support block 11 to move via the first connecting plate 8, the connecting rod 9, and the second connecting plate 10. The support block 11 drives the limiting block 13 to slide outwards inside the limiting groove 12. By using multiple support blocks 11 to hold the inner side of the coil frame, coil frames of different diameters can be fixed. This device can be adjusted according to the diameter of the coil frame, making it suitable for coil frames of different diameters. This avoids the need for workers to replace different fixing rods for different specifications of coil frames, improving the practicality and convenience of the device.

[0023] Specifically, the rotating assembly includes a motor 2 fixedly mounted at the bottom of the mounting frame 1. The output end of the motor 2 extends through the mounting frame 1 into the interior of the mounting frame 1 and is fixedly mounted with a rotating shaft 3. The rotating shaft 3 is fixedly connected to the mounting plate 4. A knob 18 is fixedly mounted at the bottom end of the drive shaft 15. The knob 18 is located at the bottom edge of the mounting plate 4. When the motor 2 is started, the rotating shaft 3 is driven to rotate. The rotation of the rotating shaft 3 drives the mounting plate 4 to rotate. The rotation of the mounting plate 4 drives the fixed plate 5 to rotate. The rotation of the fixed plate 5 causes the positions of the two sets of support blocks 11 to be exchanged, thereby changing the positions of the two coil windings fixed on the support blocks 11. This avoids the need to wait for the coil frame to be replaced after it has been wound before the next coil can be wound.

[0024] Specifically, the drive assembly includes a drive shaft 15 rotatably mounted on the bottom of the mounting plate 4. A knob 18 is fixedly mounted on the bottom end of the drive shaft 15, located at the edge of the bottom of the mounting plate 4. A drive pulley 16 is fixedly mounted on the surface of the drive shaft 15, and a synchronous belt 17 is meshed on the surface of the drive pulley 16. A driven pulley 14 is meshed inside the synchronous belt 17. The driven pulley 14 is fixedly connected to the screw 6. Rotating the knob 18 causes the drive shaft 15 to rotate, which in turn drives the drive pulley 16 to rotate. The rotation of the drive pulley 16, through the synchronous belt 17, drives the driven pulley 14 to rotate, which in turn drives the screw 6 to rotate. The knob 18, located at the edge, prevents workers from reaching inside to rotate the screw 6, thus improving the comfort of the device.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0026] In use: Place the coil holder onto the surface of one set of support blocks 11. Rotate knob 18 to rotate the drive shaft 15. The rotation of drive shaft 15 drives drive pulley 16 to rotate. Drive pulley 16, via synchronous belt 17, drives driven pulley 14 to rotate. Driven pulley 14, via synchronous belt 17, drives screw 6 to rotate. Screw 6 rotates, causing threaded sleeve 7 to move. Threaded sleeve 7 moves first connecting plate 8, which in turn moves connecting rod 9. Connecting rod 9 moves second connecting plate 10, which in turn moves support block 11. Support block 11 causes limiting block 13 to slide outwards within limiting groove 12. Multiple support blocks 11 are used to press against the inner side of the coil frame to fix the coil frame. Similarly, another coil frame is fixed above the support block 11 on the other side. The coil frame is wound by a winding machine. When the winding of one coil frame is completed, the motor 2 is started, which causes the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the mounting plate 4 to rotate, which causes the positions of the two fixing plates 5 to be swapped. This causes the support blocks 11 on the surface of the fixing plate 5 and the coil frames fixed on the surface of the support blocks 11 to be swapped, so that the coil frames that have not been wound can be wound. The coil frames that have been wound can be rotated in the opposite direction by turning the knob 18 to retract the support blocks 11, thereby removing the coil frame.

[0027] In summary, this stator coil holder fixing device uses a drive assembly to rotate the screw 6. The rotation of the screw 6 causes the threaded sleeve 7 to move linearly. The downward movement of the threaded sleeve 7 pushes the support block 11 to move via the first connecting plate 8, the connecting rod 9, and the second connecting plate 10. The support block 11 causes the limiting block 13 to slide outward inside the limiting groove 12. By having multiple support blocks 11 abut against the inner side of the coil holder, coil holders of different diameters can be fixed. This device can be adjusted according to the diameter of the coil holder, making it suitable for coil holders of different diameters. This avoids the need for workers to replace different fixing rods for different specifications of coil holders, thus improving the practicality and convenience of the device.
