Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0036] like Figure 1-12 As shown, a winding device for manufacturing an electric motor according to one embodiment of the present invention includes: a workbench 1 and a winding mechanism 2.

[0037] like Figure 1-4 As shown, a pair of first slide rods 101 are fixed on the workbench 1 for moving the moving block 102 up and down. The moving block 102 is slidably mounted on the pair of first slide rods 101. A cross arm 103 is fixed to one side of the moving block 102, and the moving block 102 drives the cross arm 103 to move up and down. A lifting rod 120 is fixed below the moving block 102. The lifting rod 120 is used to connect an external lifting device to drive it to move up and down, and the lifting rod 120 drives the moving block 102 to move up and down. A rotating rod 104 is inserted at the end of the cross arm 103 away from the moving block 102. The winding mechanism 2 is installed below the rotating rod 104. A rotating handle or a stepper motor can be externally mounted on the upper end of the rotating rod 104 to drive the rotating rod 104 to rotate. The rotating rod 104 drives the winding mechanism 2 to rotate, and then the winding mechanism 2 winds copper wire around the stator teeth at different positions.

[0038] like Figure 1-4 As shown, a clamping platform 105 is installed on the workbench 1. Multiple first slide rails 106 are cut into the clamping platform 105, and first sliders 107 are slidably mounted on each of the first slide rails 106. The first sliders 107 drive the upper fixing blocks 108 to move back and forth along the first slide rails 106, thus clamping and releasing the stator. A first screw 113 is threaded onto the first slider 107. Rotating the first screw 113 causes the first slider 107 to move back and forth on the first slide rails 106. A fixing block 108 is fixed to the first slider 107, and the first slider 107 drives the fixing block 108 to move on the first slide rails 106. A pair of second slide rods 109 are inserted into the fixing block 108 for connecting to clamping blocks 110. One end of each pair of second slide rods 109 is fixed to a clamping block 110 for clamping the stator.

[0039] like Figure 1-4 As shown, a first spring 112 is installed between the clamping block 110 and the fixing block 108 to buffer the force and prevent the stator from deforming due to excessive clamping force. A placement block 111 is fixed on the clamping block 110 for placing the stator, and a pair of second slide rods 109 are connected at the ends away from the clamping block 110.

[0040] like Figure 1-4As shown, a fixed shaft 115 is fixed inside the workbench 1. A first bevel gear 114 is rotatably mounted on the fixed shaft 115. A second bevel gear 119, the same number as the first screw 113, meshes with the first bevel gear 114. The first screw 113 is fixedly connected to the second bevel gear 119. Rotating the first bevel gear 114 drives the second bevel gear 119 to rotate, and the second bevel gear 119 drives the first screw 113 to rotate. A second gear 117 is fixed to the bottom of the first bevel gear 114. A first gear 116 meshes with one side of the second gear 117. A first drive shaft 118 is fixed to the first gear 116. The first drive shaft 118 is used to connect an external transmission device to drive its rotation. The first drive shaft 118 drives the first gear 116 to rotate, and the first gear 116 drives the second gear 117, causing the first bevel gear 114 to rotate.

[0041] like Figure 5-10 As shown, the winding mechanism 2 is mounted on the rotating rod 104. The winding mechanism 2 includes a housing 201, within which a first support rod 210 and a second support rod 211 are fixed, providing fixed support. A second drive shaft 209 is inserted into the first support rod 210 and the second support rod 211. The end of the second drive shaft 209 away from the one-way gear 207 is used to connect an external drive device to drive the second drive shaft 209 to rotate. A one-way gear 207 is mounted on one end of the second drive shaft 209. When the second drive shaft 209 rotates clockwise, it drives the one-way gear 207 to rotate; when the second drive shaft 209 rotates counterclockwise, it does not drive the one-way gear 207 to rotate. A gear ring 203 is rotatably mounted on the housing 201, and a pair of third gears 208 are arranged between the gear ring 203 and the one-way gear 207.

[0042] like Figure 5-10 As shown, a pair of second slide rails 215 are fixed inside the outer casing 201. A second slider 216 is slidably mounted on each of the second slide rails 215. A telescopic rod 205 is fixed on each of the second sliders 216. The telescopic rod 205 is engaged with the second slide rail 215 via the second slider 216, preventing rotation of the telescopic rod 205 and allowing it to move back and forth along the track of the second slide rail 215. A winding roller 202 is installed outside the outer casing 201 for holding copper wire.

[0043] like Figure 5-10As shown, a pair of third gears 208 mesh with the gear ring 203 and the one-way gear 207 respectively. The third gears 208 are rotatably mounted on the first support rod 210 to prevent displacement and ensure that the third gears 208 only rotate. A winding head 204 is fixed on the one-way gear 207. The second drive shaft 209 drives the one-way gear 207 to rotate, and the one-way gear 207 drives the gear ring 203 to rotate through the third gears 208. A guide plate 206 is fixed to one end of the telescopic rod 205 outside the outer casing 201 to guide the copper wire to be wound onto the stator core. A second screw 214 is fixed to the end of the telescopic rod 205 away from the guide plate 206. The second screw 214 drives the guide plate 206 to move back and forth through the telescopic rod 205.

[0044] like Figure 5-10 As shown, a threaded gear 212 is threadedly connected to the second screw 214. The threaded gear 212 is rotatably mounted on the second support rod 211 to prevent the position of the threaded gear 212 from shifting, allowing the threaded gear 212 to rotate. Since the telescopic rod 205 is locked inside the second slide rail 215 by the second slider 216, the telescopic rod 205 will not rotate, and therefore the second screw 214 will not rotate either. When the threaded gear 212 rotates, since the position of the threaded gear 212 is restricted on the second support rod 211, the rotation of the threaded gear 212 drives the second screw 214 to move back and forth. The second screw 214 drives the telescopic rod 205 to move back and forth. A fourth gear 213 is fixed on the second transmission shaft 209. The fourth gear 213 meshes with a pair of threaded gears 212. The second transmission shaft 209 drives the fourth gear 213 to rotate, and the fourth gear 213 drives the threaded gear 212 to rotate.

[0045] like Figure 10-12 As shown, a fixed head 221 is fixed to one end of the second drive shaft 209 inside the one-way gear 207. The second drive shaft 209 drives the fixed head 221 to rotate. A locking slot 220 is chiseled on the fixed head 221 for installing a locking block 218. The locking block 218 is rotatably disposed in the locking slot 220 and is used to lock the one-way gear 207. A slot 217 is cut into the one-way gear 207, and a locking block 218 is locked in the slot 217. When the second drive shaft 209 rotates clockwise, the locking block 218 is locked in the slot 217. The second drive shaft 209 drives the one-way gear 207 to rotate through the fixing head 221. When the second drive shaft 209 rotates counterclockwise, the one-way gear 207 pushes the locking block 218 into the locking block groove 220. The second drive shaft 209 does not drive the one-way gear 207 to rotate. A second spring 219 is fixed between the locking block 218 and the inner wall of the locking block groove 220. The elastic force provided by the second spring 219 pushes the locking block 218 into the locking groove 217.

[0046] Working principle: Before use, both the first drive shaft 118 and the second drive shaft 209 need to be connected to external drive devices to drive them to rotate. The lifting rod 120 is connected to an external lifting device to drive it to move up and down. The rotating rod 104 is connected to an external rotating handle or stepper motor. First, place the stator to be wound on the placement block 111. Then, start the drive device at the first drive shaft 118 to drive the first drive shaft 118 to rotate. The first drive shaft 118 drives the first gear 116 to rotate. The first gear 116 drives the second gear 117 to make the first bevel gear 114 rotate. The first bevel gear 114 drives the second bevel gear 119 to rotate. The second bevel gear 119 drives the first screw 113 to rotate, causing the first slider 107 to move back and forth on the first slide rail 106. The first slider 107 drives the clamping block 110 to move towards the stator through the fixing block 108 to clamp the stator. Then, turn off the drive device at the first drive shaft 118.

[0047] Then, the lifting device at the lifting rod 120 is activated, which drives the moving block 102 to move downward. The moving block 102 drives the winding mechanism 2 below the rotating rod 104 to move downward through the horizontal arm 103. When the winding mechanism 2 descends to the appropriate winding position, the lifting device is closed. Then, the drive device connected to the second transmission shaft 209 is activated, which drives the second transmission shaft 209 to rotate counterclockwise. The second transmission shaft 209 drives the fourth gear 213 to rotate counterclockwise. The fourth gear 213 drives the threaded sleeve gear 212 to rotate, which drives the threaded sleeve gear 212 to drive the second screw 214 to move forward. The second screw 214 drives the telescopic rod 205 to move forward. The telescopic rod 205 drives the guide plate 206 to move towards the stator. After moving to the inner position of the stator tooth pole, the drive device is closed. The counterclockwise rotation of the second transmission shaft 209 does not drive the one-way gear 207 to rotate. Therefore, at this time, only the guide plate 206 is sent into the inner position of the stator tooth pole, and copper wire winding is not performed.

[0048] Then, the drive device connected to the second drive shaft 209 is activated, causing the second drive shaft 209 to rotate clockwise. When the second drive shaft 209 rotates clockwise, it drives the one-way gear 207 to rotate. The one-way gear 207 drives the third gear 208 to rotate, causing the gear ring 203 to rotate. The gear ring 203 drives the winding head 204 to wind copper wire around the stator teeth. At the same time, the second drive shaft 209 also drives the fourth gear 213 to rotate. The fourth gear 213 drives the threaded sleeve gear 212 to rotate, causing the threaded sleeve gear 212 to drive the second screw 214 to move backward. The second screw 214 drives the telescopic rod 205 to move backward. The telescopic rod 205 drives the guide plate 206 to move backward slowly, so that the winding head 204 winds the copper wire evenly from the inside out.

[0049] Finally, by rotating the rotating rod 104, the winding mechanism 2 is rotated to wind copper wire around the stator teeth at other positions of the stator.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
