Description

Technical Field

[0001] The invention relates to the technical field of motor stator processing, in particular to a winding machine for motor stator coils. Background Art

[0002] The motor stator is an important component of the motor, which consists of a stator core, a stator winding and a frame. The stator coil is a key component of the motor stator part and needs to be produced by a winding machine. The winding machine winds the insulated wire into the slots of the stator core in a predetermined manner to form the stator winding of the motor. The efficiency and quality of motor production can be significantly improved by an automated winding machine.

[0003] At present, the winding machines used for motor stator coils still have certain shortcomings. For example, when installing the stator, the staff needs to manually turn the pressure rod, which reduces the working efficiency of the stator automatic winding machine. In addition, the automatic winding machine cannot achieve simultaneous winding of multiple parts of the stator, making it difficult to improve the efficiency of automatic winding: In order to overcome the problem that the stator automatic winding machine requires the staff to manually rotate the pressure rod, which reduces the working efficiency of the stator automatic winding machine, the Chinese patent of the prior art (publication number: CN218387199U) discloses an automatic stator winding machine. When the stator needs to be installed, the staff installs the stator on the mounting seat, and then resets the driving cylinder to displace the clamping block, and the rotating rod is rotated by the clamping block to achieve the effect of clamping the stator with the clamping block; when the stator needs to be removed, the staff starts the driving cylinder to displace the clamping block in the opposite direction, and the rotating rod is lifted by the tension of the tension spring, and the clamping block is away from the stator, so that the stator can be removed. The staff uses the clamping assembly to automatically clamp the stator, which reduces the labor intensity of the staff, speeds up the installation speed of the stator, and improves the working efficiency of the stator automatic winding machine; In order to overcome the problem that the automatic winding machine cannot realize the winding of multiple parts of the stator at the same time and it is difficult to improve the efficiency of automatic winding, the Chinese patent of the prior art (publication number: CN115622348B) discloses an automatic winding machine for motor windings. The automatic winding machine for motor windings solves the problem that the existing automatic winding machine cannot realize the winding of multiple parts of the stator at the same time, thereby improving the efficiency of automatic winding. In addition, after the winding is completed, some of them still need to manually cut the copper wire; In order to overcome the low efficiency of the sub-winding process, the Chinese patent of the prior art (publication number: CN112202301A) discloses a fully automatic stator winding machine for winding on a stator winding frame. A wire clamping mechanism and a wire cutting mechanism are also provided on one side of the winding mechanism. The wire ends are sent to the wire clamping mechanism through the wire feeding mechanism and clamped at the wire clamping mechanism to start working. After the winding wire is wound on the split frame through the winding mechanism, it returns to the wire clamping mechanism and the wire cutting mechanism, and the returned winding wire is cut off. After removing the original wire ends and the returned wire ends, the wound stator winding frame is removed from the winding machine, and the empty split frame is replaced to start a new winding work. The winding machine with such a structure allows the companies using it to improve production efficiency and save labor costs; However, the winding machines currently used for motor stator coils still have certain shortcomings. In the above-mentioned documents, the staff installs the stator on the mounting seat, and then resets the driving cylinder to displace the clamping block. The rotating rod is rotated by the clamping block to achieve the effect of clamping the stator with the clamping block. The clamping of the stator is not multi-faceted, and the direction of the extrusion force is transmitted on one side. There is a deviation during winding, and the stator is not clamped stably and is prone to skewness, which affects the winding accuracy. It is difficult to perform correct winding after skewness, which affects the product quality of the stator coil. Therefore, it is necessary to improve the existing structure.

The surface of the eccentric block 205 is rotatably connected to the first rotating block 206, and the side of the first rotating block 206 is rotatably connected to the movable block 207. The movable block 207 penetrates and slides inside the through groove 203. A connecting rod 208 is fixed on the side of the movable block 207, and an extrusion block 209 is fixed on the bottom of the connecting rod 208. When the winding machine is working, the stator coil will be processed on the surface of the workbench 1, and the stator will be placed at the position specified by the processing seat 2 The stator before winding the coil is fixed and clamped. After the stator is fixed, the machine will drive the stator to the processing position, and then move the wire to the side of the stator through the output end of the winding device 3. The output end of the winding device 3 winds the coil on the stator surface through its own rotation and expansion characteristics. While winding, the coil can be guided along the stator surface through the wire device 4, and the coil is wound on the stator surface in sequence in conjunction with the winding of the coil.

When the connecting rod 208 moves, it can drive the extrusion block 209 to move. When the extrusion block 209 moves to the side of the stator, it can be extruded. The simultaneous extrusion of the four groups of extrusion blocks 209 on the side of the stator can improve the stability of the extrusion, thereby improving the effect of the stator winding.

[0020] Embodiment 2:

[0021] like Figure 2 , Figure 5 , Figure 6 and Figure 7 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the clamping mechanism of the winding machine stator has many restrictions on the stator specifications and the stator with larger or smaller specifications cannot be processed, an adjustment mechanism is disclosed: The adjustment mechanism includes a sliding groove 211, which is provided on the right side of the external block 210. A sliding block 212 is slidably inserted into the sliding groove 211. The sliding block 212 is fixed to the side of the connecting rod 208 away from the extrusion block 209. A telescopic groove 213 is provided on the side of the sliding block 212. A telescopic block 214 is slidably inserted into the telescopic groove 213. A first spring 215 is connected between the telescopic block 214 and the telescopic groove 213. The telescopic block 214 forms a telescopic structure with the telescopic groove 213 through the first spring 215. A fixed rod 214 is fixed to the side of the telescopic block 214 close to the telescopic groove 213. 16, the fixing rod 216 penetrates and slides inside the sliding block 212 and the connecting rod 208, and a snap-fit ​​groove 217 is provided on the side of the sliding groove 211. The snap-fit ​​groove 217 is provided in multiple groups, and the snap-fit ​​groove 217 is snap-fitted with the telescopic block 214. The stator size is different. When a larger or smaller stator needs to be processed, the clamping component needs to be replaced, otherwise the stator clamping is likely to be unstable, which is easy to reduce the quality of the stator coil winding. If the clamping component is replaced, the replacement method is usually threaded, and it will take a long time to replace a set of components. Therefore, when the stator clamp is replaced, the stator clamp is replaced. Before holding, by pulling the fixed rod 216, it can slide through the sliding block 212 and the connecting rod 208. When the fixed rod 216 slides, it can pull the telescopic block 214 to move. The telescopic block 214 can slide through the telescopic groove 213 and the engaging groove 217. When the telescopic block 214 slides, it can squeeze the first spring 215. When the telescopic block 214 squeezes out of the engaging groove 217, it pushes the connecting rod 208 up and down. When the connecting rod 208 is pushed, it can drive the sliding block 212 to move. When the sliding block 212 moves, it can slide through the telescopic groove 213. The sliding block 212 When sliding, the telescopic block 214 can be driven to move. When the telescopic block 214 moves to the side of the engaging groove 217 of other groups, the fixing rod 216 is released. When the fixing rod 216 is released, the first spring 215 can push the telescopic block 214 to reset by its own elastic force. When the telescopic block 214 is reset, it can be engaged and positioned with the engaging groove 217 of other groups. When the telescopic block 214 is positioned, it can drive the connecting rod 208 to be positioned. When the connecting rod 208 is positioned, the range of clamping the stator can be adjusted, which reduces the restrictions on the specifications of the stator and does not need to replace the clamping parts, thereby improving the efficiency of the stator winding in disguise.

[0022] Embodiment three:

[0023] like Figure 5 , Figure 8 and Fig. 9 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that there are many types of winding machine stators, when clamping the stator outside, it is necessary to replace parts to fix the inside of the stator, which affects the stator processing efficiency, a rotating mechanism is disclosed: The rotating mechanism includes a third rotating groove 219, which is symmetrically arranged at the upper and lower sides of the external block 210. The third rotating groove 219 is internally rotatably connected with a second rotating block 220, and a second spring 221 is connected between the second rotating block 220 and the third rotating groove 219. A second rotating block 222 is fixed to the side of the movable block 207, and the second rotating block 222 is rotatably connected to the second rotating groove 218. A positioning groove 223 is arranged on the top of the movable block 207, and the positioning groove 223 is engaged with the second rotating block 220. There are various types of stators, and there are also many ways to clamp and fix the stator, which are usually mechanical clamping and hydraulic clamping. The clamping is divided into internal clamping and external clamping. The internal clamping is The clamping is usually achieved by the inner diameter or inner hole of the stator, which is suitable for the case where the stator has a center hole. The external clamping is usually achieved by the outer diameter or outer surface of the stator, which is suitable for the case where the stator has no obvious inner hole or the internal structure is not suitable for clamping. Most of the market replaces the internal and external clamping by replacing the clamping parts, and the operation process is relatively cumbersome. When the winding machine needs to be fixed by internal clamping, the upper and lower second rotating blocks 220 are rotated by hand. When the top second rotating block 220 is pushed, it can rotate through the third rotating groove 219. At the same time, the protrusion at the bottom of the second rotating block 220 can rotate inside the positioning groove 223. When the second rotating block 220 rotates, it passes through the third rotating groove 21 9 can stretch the second spring 221, and the end of the second rotating block 220 can be rotated out of the positioning groove 223 when it is stretched. At this time, rotating the external block 210 can drive the second rotating groove 218 to rotate. When the second rotating groove 218 rotates, it can rotate through the second rotating block 222. The rotation of the external block 210 can drive the two second rotating blocks 220 to rotate. When the external block 210 rotates 180 degrees, the two second rotating blocks 220 at the bottom can be swapped. At this time, the second rotating block 220 at the bottom can be rotated to the top, and the second rotating block 220 at the bottom will rotate to the top of the positioning groove 223. At this time, the second rotating block 220 is released through the second spring 22 1 can be reset by its own elastic tension. When the second rotating block 220 at the bottom is reset, the convex block at the bottom can be engaged with the positioning groove 223 for positioning. When the second rotating block 220 is positioned, it can drive the external block 210 to be positioned. When the external block 210 is positioned, it can drive the extrusion block 209 to be positioned. At this time, the extrusion block 209 is flipped. When the extrusion block 209 is flipped, the connecting rod 208 can be moved outward by reverse operation of the clamping mechanism. When the connecting rod 208 moves outward, the extrusion block 209 can extrude, support and fix the inside of the stator. The winding machine can adapt to various types of stators, is easy to operate, can better adapt to production needs, and once again improves the efficiency and effect of the winding process.
