Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and more specifically, to a motor rotor coil welding device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. During the production of electric motors, coil welding of the motor rotor is often required. For example, a rotor coil welding machine proposed in application number "CN202323265652.1" includes a machine body, a worktable mounted on the machine body, a welding head mounted on the machine body, a pneumatic chuck mounted on the machine body, and a placement device for placing the rotor. The placement device includes a base fixedly connected to the worktable and a placement block fixedly connected to the base. The placement block has a placement groove for placing the rotor at its end away from the worktable, and the placement groove has a V-shaped cross-section. This application has the effect of making the rotor placement more stable during processing and facilitating the operator to use the pneumatic chuck to fix the rotor shaft.

[0003] However, although the above technical solutions can fix the rotor shaft with pneumatic chucks to improve its stability, when multiple coils on the rotor shaft need to be welded, it often relies on the user to manually control the rotor shaft to rotate continuously. This method not only consumes a lot of manpower and time costs, but also makes it difficult to guarantee the accuracy and stability of each rotation due to manual operation, resulting in inconsistent welding quality and seriously affecting the overall processing efficiency. Therefore, we propose a motor rotor coil welding device to solve the above problems. Utility Model Content

[0026] like Figures 4 to 8As shown, in another embodiment of this utility model, the upper surface of the support platform 1 is provided with a movable groove 206, and a second turntable 207 is movably installed inside the movable groove 206. An upper toothed ring 208 is installed on the upper surface of the second turntable 207, and an inner toothed ring 209 is provided on the side of the second turntable 207 near the first rotating block 219. A placement groove 212 is provided inside the support platform 1 and at one end near the movable groove 206, and the placement groove 212 is connected to the movable groove 206. A motor 211 is installed at the lower end of the placement groove 212, and a motor 211 is installed at the upper end of the placement groove 212. A second gear 210 is provided, which meshes with an internal gear ring 209. The output end of the motor 211 is connected to the second gear 210. A positive and negative lead screw 213 is movably installed through the middle of the slide groove 202. The shaft of the positive and negative lead screw 213 is threaded through and installed inside the clamping frame 204. First gears 205 are respectively installed at both ends of the shaft of the positive and negative lead screw 213. The first gears 205 are movably installed through and installed on the lower ends of both sides of the first turntable 201, and the first gears 205 mesh with an upper gear ring 208. The first turntable... An auxiliary groove 214 is provided in the middle of the interior of 201, and the rod body of the positive and negative lead screw 213 is movably installed through the interior of the auxiliary groove 214. A friction disc 215 is installed on the outer side of the rod body of the positive and negative lead screw 213 inside the auxiliary groove 214. A locking frame 216 is movably installed inside the auxiliary groove 214, and a friction groove 217 is provided through the interior of the locking frame 216. The friction disc 215 is movably installed through the interior of the friction groove 217, and the outer side of the friction disc 215 is engaged with the upper end of the interior of the friction groove 217. A first cylinder 225 is installed at the lower end of the interior of the connecting groove 218. The output end of the first cylinder 225 is movably located at the upper end of the connecting groove 218. An extension rod 220 is movably installed through the lower end of the auxiliary groove 214. A second rotating block 221 is fixedly installed at the lower end of the extension rod 220, and the second rotating block 221 is engaged inside the output end of the first cylinder 225.

A limit groove 222 is provided on the lower surface of the first rotating block 219, and the limit bracket 223 is engaged inside the fiber limit groove 222.

[0027] When it is necessary to weld coils onto the raw material, the user places the raw material between the clamping frames 204. Then, the first cylinder 225 pushes the push plate 224 and the extension rod 220 upwards, causing the push plate 224 to drive the limiting frame 223 into the limiting groove 222, thereby positioning the first rotating block 219 and the first turntable 201. Then, the extension rod 220 pushes the engaging frame 216 upwards, causing the engaging frame 216 to separate the friction groove 217 and the friction disc 215. Then, the user... The motor 211 can be started, causing the second gear 210 to rotate. The second gear 210 then engages with the internal gear ring 209 to control the rotation of the second turntable 207. The second turntable 207 then drives the upper gear ring 208 to rotate, which in turn drives the first gear 205 to rotate. The first gear 205 then drives the positive and negative lead screws 213 to rotate, allowing the lead screws 213 to control the clamping frame 204 to clamp and position the raw material via the thread. After the positioning is completed, motor 211 stops working. Then, the first cylinder 225 pulls the push plate 224 and the locking bracket 216 downwards, causing the push plate 224 to separate the limiting bracket 223 and the limiting groove 222. At the same time, the locking bracket 216 also causes the friction groove 217 to move downwards, so that the friction groove 217 and the friction disc 215 are engaged and connected, thereby achieving the tensioning and locking of the friction disc 215 and the positive and negative lead screws 213, preventing the positive and negative lead screws 213 and the friction disc 215 from rotating. Then, motor 211 can... The second turntable 207 is then rotated again. The second turntable 207, through the upper gear ring 208 and the locked first gear 205, controls the first turntable 201 and the raw material to rotate around the first rotating block 219 as the axis, thereby adjusting the required welding angle of the raw material. After each adjustment of the raw material angle, the electric slide rail 4, in conjunction with the slider 5, controls the height of the welding head 7. After the height adjustment is completed, the second cylinder 6 pushes the welding head 7 toward the coil to complete the welding work.

[0028] The working principle of this motor rotor coil welding device:

[0029] In use, when it is necessary to weld the coil on the raw material, the user places the raw material between the clamping frames 204. Then, the first cylinder 225 pushes the push plate 224 and the extension rod 220 upward, causing the push plate 224 to drive the limiting frame 223 into the limiting groove 222, thereby positioning the first rotating block 219 and the first turntable 201. Then, the extension rod 220 pushes the locking frame 216 upward, causing the locking frame 216 to separate the friction groove 217 and the friction disc 215. The user can then start the motor 211, causing it to drive the second gear 210 to rotate. The second gear 210, in turn, engages with the internal gear ring 209 to control the rotation of the second turntable 207. The second turntable 207 then drives the upper gear ring 208 to rotate, which in turn drives the first gear 205 to rotate. This first gear 205 then drives the positive and negative lead screws 213 to rotate, allowing the lead screws 213 to control the clamping frame 204 to clamp and position the material via the thread. After clamping and positioning are completed, motor 211 stops working. Then, the first cylinder 225 pulls the push plate 224 and the locking frame 216 downwards, causing the push plate 224 to separate the limiting frame 223 and the limiting groove 222. At the same time, the locking frame 216 also causes the friction groove 217 to move downwards, so that the friction groove 217 and the friction disc 215 are engaged and connected, thereby achieving the tensioning and locking of the friction disc 215 and the positive and negative lead screws 213, preventing the positive and negative lead screws 213 and the friction disc 215 from rotating. Then, motor 211... The second turntable 207 can be controlled to rotate again. Then, the second turntable 207 can control the first turntable 201 and the raw material to rotate around the first rotating block 219 through the upper gear ring 208 and the locked first gear 205, so as to adjust the required welding angle of the raw material. After each adjustment of the raw material angle is completed, the electric slide rail 4 can cooperate with the slider 5 to control the height of the welding head 7. After the height adjustment is completed, the second cylinder 6 can push the welding head 7 towards the coil to realize the welding work.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
