Detailed Implementation

[0032] 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.

[0033] like Figures 1 to 9 As shown, a spot welding device for motor manufacturing in one embodiment of the present invention includes: device body 1 and fixing device 2.

[0034] like Figures 1 to 4As shown, a support platform 101 and a processing table 102 are fixed on the main body 1 of the device, serving as a fixed support. A toothed plate 103 is installed on the support platform 101, and a slide rail 106 is fixed to one end of the toothed plate 103 located below the support platform 101. The toothed plate 103 drives the slide rail 106 to move up and down. A first slider 107 is slidably arranged on the slide rail 106, and a support plate 108 is fixed on the first slider 107. The first slider 107 drives the support plate 108 to move on the slide rail 106. A first gear 104 is installed on the support platform 101, and the first gear 104 meshes with the toothed plate 103. A crank handle 105 is connected to the outside of the support platform 101 for the first gear 104. By turning the crank handle 105, the first gear 104 is rotated, thereby driving the toothed plate 103 to move up and down.

[0035] like Figures 1 to 4 As shown, a pair of meshing second gears 112 are rotatably mounted on the support plate 108. When the pair of second gears 112 mesh and rotate, they clamp or separate. Each of the pair of second gears 112 has a connecting arm 113 fixed to it, and a welding probe 114 is fixed to the connecting arm 113. The connecting arms 113 clamp or release the welding probe 114, thus spot welding the rotor enameled wire. One of the second gears 112 is connected to a throttle 111. Rotating the throttle 111 rotates one of the second gears 112, thereby causing the pair of meshing second gears 112 to rotate. A telescopic cylinder 109 is mounted on the support plate 108, and a telescopic rod 110 is mounted on the telescopic cylinder 109. The telescopic rod 110 is rotatably connected to the telescopic cylinder 109. The telescopic cylinder 109 drives the telescopic rod 110 to extend and retract, thereby rotating the throttle 111.

[0036] like Figures 5 to 9 As shown, the fixing device 2 is installed on the processing table 102. The fixing device 2 includes a placement table 201, on which several first sliding grooves 202 are carved. Second sliders 203 are slidably disposed within each of the first sliding grooves 202. A clamping body 204 is fixedly connected to one end of each second slider 203 outside the placement table 201. The second slider 203 drives the clamping body 204 to move along the trajectory of the first sliding grooves 202. A main shaft 205 is inserted into the placement table 201, and a third gear 207 is fixed to one end of the placement table 201. The third gear 207 drives the placement table 201 to rotate. A fixed shaft 217 is provided on one side of the third gear 207. The fixed shaft 217 is installed on the processing table 102 and is detachable, allowing for the replacement of intermittent gears 216 with different numbers of teeth. A fourth gear 215 is rotatably disposed on the fixed shaft 217, and a fixing block 223 is fixed on the processing table 102.

[0037] like Figures 5 to 9As shown, one end of the main shaft 205 is fixed with connecting rods 212, the same number as the clamping body 204. Rollers 214 are rotatably mounted on the ends of the connecting rods 212 away from the main shaft 205. The main shaft 205 drives the rollers 214 to move up and down via the connecting rods 212. A second groove 213 is carved into the clamping body 204. The rollers 214 are slidably disposed within the second groove 213. The main shaft 205 drives the rollers 214 to move up and down via the connecting rods 212. The rollers 214 slide within the second groove 213, causing the clamping body 204 to move inward or outward, thereby clamping or releasing the rotor.

[0038] like Figures 5 to 9 As shown, a limiting head 208 is fixed at the end of the main shaft 205 away from the connecting rod 212. A spring 206 is fixed between the limiting head 208 and the inner wall of the placement table 201. The elastic force provided by the spring 206 causes the limiting head 208 to move away from the placement table 201. The limiting head 208 drives the connecting rod 212 to move downward through the main shaft 205. The connecting rod 212 drives the roller 214 to move downward. The roller 214 slides downward in the second slide groove 213, driving the clamp 204 to move outward, thereby achieving the clamping of the rotor. A rotating rod 209 is rotatably mounted on the fixed block 223. An upper pressure head 210 is fixed to one end of the rotating rod 209 below the limiting head 208. A handle 211 is fixed to the other end of the rotating rod 209 away from the upper pressure head 210. By pressing down the handle 211, the upper pressure head 210 is driven to push the limiting head 208 upward, thereby causing the connecting rod 212 to drive the roller 214 to slide upward in the second slide groove 213, causing the clamp 204 to move inward and release the rotor.

[0039] like Figures 5 to 9 As shown, a connector 222 is fixed on the fourth gear 215, and an intermittent gear 216 is installed on the connector 222. The intermittent gear 216 meshes with the third gear 207. When the toothed part of the intermittent gear 216 meshes with the third gear 207, it drives the third gear 207 to rotate, realizing the intermittent rotation of the third gear 207. By replacing the intermittent gear 216 with different numbers of teeth, the third gear 207 can rotate intermittently at different angles. The third gear 207 drives the placement platform 201 to rotate. A slot 221 is carved on the fourth gear 215, and a block 220 is fixed on the intermittent gear 216. The block 220 is inserted into the slot 221. By inserting the block 220 into the slot 221, the rotation of the fourth gear 215 drives the intermittent gear 216 to rotate. The fourth gear 215 is meshed with the fifth gear 218 on one side. The fifth gear 218 is connected to the drive motor 219 below. The drive motor 219 drives the fifth gear 218 to rotate, and the fifth gear 218 drives the fourth gear 215 to rotate. The drive motor 219 is fixed on the main body 1 of the device.

[0040] Working principle: First, take a rotor to be welded. Press down the handle 211 to drive the upper pressure head 210 to push the limiting head 208 upward. The limiting head 208 drives the connecting rod 212 to move upward through the main shaft 205. The connecting rod 212 drives the roller 214 to slide upward in the second slide groove 213, causing the clamping body 204 to move inward. Then, place the rotor on the placement table 201. Then release the handle 211. The elastic force provided by the spring 206 moves the limiting head 208 away from the placement table 201. The limiting head 208 drives the connecting rod 212 to move downward through the main shaft 205. The connecting rod 212 drives the roller 214 to move downward. The roller 214 slides downward in the second slide groove 213, causing the clamping body 204 to move outward, thereby achieving the clamping and fixing of the rotor.

[0041] Then, by turning the rocker handle 105, the first gear 104 is driven to rotate, thereby driving the toothed plate 103 to move downward. The toothed plate 103 drives the first slider 107 to move downward through the slide rail 106. After moving to the appropriate position, the first slider 107 is pushed to move left and right on the slide rail 106 to the appropriate position. The enameled wire to be welded is placed between a pair of welding probes 114. Then, the number of rotor enameled wires to be welded in one revolution of the rotor is determined. The fixed shaft 217 is removed and replaced with an intermittent gear 216 with a relative number of teeth, so that the gap rotation angle of the third gear 207 is consistent with the angle of every two rotor enameled wires to be welded. Then, the welding equipment is started. The telescopic cylinder 109 drives the telescopic rod 110 to extend and retract back and forth, thereby rotating the handle 111. The handle 111 drives one of the second gears 112 to rotate, thereby driving a pair of second gears 112 to rotate in mesh. When the pair of second gears 112 rotate in mesh, they drive a pair of welding probes 114 to clamp or loosen each other, thereby spot welding the rotor enameled wire.

[0042] Meanwhile, the drive motor 219 below drives the fifth gear 218 to rotate, the fifth gear 218 drives the fourth gear 215 to rotate, the fourth gear 215 drives the intermittent gear 216 to rotate, and when the intermittent gear 216 rotates, the toothed part meshes with the third gear 207, driving the third gear 207 to rotate, realizing the intermittent rotation of the third gear 207. The third gear 207 drives the placement platform 201 to rotate intermittently, realizing the welding of the enameled wire on one circle of the rotor. After the welding is completed, simply press down the handle 211 to release and remove the rotor.
