Description

Technical Field

[0001] The invention relates to the technical field of magnetic core tube welding, and specifically provides an electromagnet magnetic core tube welding positioning device. Background Art

[0002] An electromagnet is a device that generates motion by generating electromagnetism through electric current. The strength, presence and direction of the electromagnet's magnetism can be controlled by controlling the current. The magnetic core tube is the core component of the electromagnet. The magnetic core tube is divided into two parts: an iron core and a guide sleeve. The existing processing technology of the magnetic core tube is to use a CNC lathe to process the iron core and the guide sleeve separately. Usually, an automatic or semi-automatic arc or plasma arc welding machine is used to weld the magnetic isolation ring to weld the iron core and the guide sleeve into one.

[0003] The patent with publication number CN110181202A discloses an automatic copper welding device for magnetic core tubes, which also includes a magnetic core tube loading and unloading mechanism, a clamping mechanism, and a heating device. The magnetic core tube loading and unloading mechanism includes a three-dimensional movable slide mechanism, a rotating cylinder is fixedly connected to the three-dimensional movable slide mechanism, and two sets of parallel pneumatic fingers are fixedly connected to the rotating cylinder; the clamping mechanism includes a fixed top mechanism and a mobile top mechanism, the fixed top mechanism includes a top spindle with a conical head, and the tail end of the top spindle is rotatably connected to the frame through a bearing, and the mobile top mechanism includes a tailstock, and the mobile top with a conical head is rotatably arranged on the tailstock through a bearing, and the tailstock is slidably arranged on the tailstock slide rail, and the tailstock is connected to the tailstock drive cylinder; the heating device is a high-frequency heating coil heating device. This device realizes the automatic welding of magnetic core tubes.

[0004] After improving the electromagnetic core tube welding positioning device, this application uses automatic loading and unloading and automatic welding of the core tube, and uses a high-frequency heating coil for preheating before welding, which can ensure welding strength and improve welding quality. The exhaust hole can effectively discharge the expanded gas caused by the welding temperature rise in time. The splash-proof sleeve can prevent copper from splashing onto the iron core and affecting product quality. The automatic welding cleaning device can automatically clean the welding slag after the welding gun is moved above the spring. However, there is no special grinding device when copper welding the magnetic isolation ring to weld the iron core and the guide sleeve into one, so manual grinding is required before welding. Therefore, we propose an electromagnetic core tube welding positioning device. Summary of the invention

[0015] 2. The present invention uses a welding mechanism to weld the first magnetic core tube and the second magnetic core tube after grinding and cleaning. The motor drives the third rotating rod to rotate, and then the third threaded rod pushes the third clamping block to clamp and fix the first magnetic core tube. After placing the second magnetic core tube above the placement table, the moving telescopic rod drives the positioning rod to insert into the second magnetic core tube, and then it can drive the second magnetic core tube to move above the first magnetic core tube by expanding with the top block. Then, the positioning rod inserts into the hole in the first magnetic core tube to achieve the positioning function. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The transmission mechanism 5 includes a motor 501 fixedly connected to the upper surface of the welding table 1. On the output shaft of the motor 501, a transmission rod 502 is fixedly connected. On the outer surface of the transmission rod 502, a first transmission wheel 503, a first trapezoidal gear 504, a second trapezoidal gear 505, and a third trapezoidal gear 506 are fixedly connected. On the upper surface of the welding table 1, a first rotating rod 507, a second rotating rod 508, and a third rotating rod 509 are rotatably connected. On the outer surface of the first rotating rod 507, a fourth trapezoidal gear 510 is fixedly connected. On the outer surface of the second rotating rod 508, a fifth trapezoidal gear 511 is fixedly connected. On the outer surface of the third rotating rod 509, a sixth trapezoidal gear 512 is fixedly connected. Inside the lower end of the welding table 1, a double-layer transmission wheel 514 is rotatably connected. On the outer surface of the first transmission wheel 503, a first transmission belt 513 is connected in transmission. On the outer surface of the double-layer transmission wheel 514, a second transmission belt 515 is connected in transmission. The first trapezoidal gear 504 and the fourth trapezoidal gear 510 are meshed and connected. The second trapezoidal gear 505 and the fifth trapezoidal gear 511 are meshed and connected. The third trapezoidal gear 506 and the sixth trapezoidal gear 512 are meshed and connected. The double-layer transmission wheel 514 and the first transmission wheel 503 are connected in transmission through the first transmission belt 513.

[0022] Furthermore, by starting the motor 501 to drive the transmission rod 502 to rotate, the first trapezoidal gear 504, the second trapezoidal gear 505, and the third trapezoidal gear 506 can be driven to rotate at the same time. At the same time, through the first trapezoidal gear 504, the second trapezoidal gear 505, and the third trapezoidal gear 506, the fourth trapezoidal gear 510, the fifth trapezoidal gear 511, and the sixth trapezoidal gear 512 are driven to rotate, so as to simultaneously drive the clamping mechanisms inside the grinding and cleaning mechanism 2, the drying mechanism 3, and the welding mechanism 4 to perform clamping.

[0023] The grinding and cleaning mechanism 2 includes a first fixed shell 201 fixedly connected to the upper surface of the welding table 1. A first moving cover 202 is slidably connected inside the first fixed shell 201. A water spray port 203 is fixedly connected inside the first fixed shell 201. A first threaded rod 206 is threadedly connected inside the first rotating rod 507. One end of the first threaded rod 206 is fixedly connected to a first moving block 207. A first push rod 208 is slidably connected inside the first moving block 207. One end of the first push rod 208 is fixedly connected to a first clamping block 210.

A grinding head 205 is fixedly connected to the lower surface of the first electric telescopic rod 204.

[0024] Further, when the first magnetic core tube 8 moves into the grinding and cleaning mechanism 2, the motor 501 is started to rotate the first rotating rod 507. Then the first threaded rod 206 pushes the first moving block 207 to move inward. Thus, the first moving block 207 compresses the first spring 209 to push the first clamping block 210 to move. The first clamping blocks 210 on both sides of the first magnetic core tube 8 move towards the middle simultaneously, which can clamp and fix the first magnetic core tube 8. Therefore, it can prevent the first magnetic core tube 8 from moving during the grinding of the first magnetic core tube 8.

A second moving cover 302 is slidably connected inside the second fixed shell 301. A telescopic cylinder 303 is fixedly connected to the upper surface of the second fixed shell 301.

A second threaded rod 307 is threadedly connected inside the second rotating rod 508. One end of the second threaded rod 307 is fixedly connected to a first limiting rod 308. A second moving block 309 is slidably connected to the upper surface of the welding table 1. One end of the second moving block 309 is fixedly connected to a fixed chuck 310. A second push rod 311 is slidably connected inside the second moving block 309. One end of the second push rod 311 is fixedly connected to a second clamping block 313. A second spring 312 is sleeved on the outer surface of the second push rod 311. A second limiting groove 315 and a first limiting groove 314 are formed inside the second fixed shell 301. A second limiting rod 316 is fixedly connected to the side surface of the second moving block 309. The second limiting rod 316 is slidably connected inside the second limiting groove 315. The first limiting rod 308 is slidably connected inside the first limiting groove 314. The fixed chuck 310 is slidably connected inside the first limiting rod 308. The rear end of the second limiting groove 315 is inclined upward.

[0026] Further, when clamping the first magnetic core tube 8 inside the drying mechanism 3, the first limiting rod 308 pushes the second moving block 309 to move towards the middle. When the second limiting rod 316 moves inside the second limiting groove 315 to the middle of the second limiting groove 315 and continues to move, the second moving block 309 will move upward according to the shape of the first transmission belt 513, so as to lift the clamped first magnetic core tube 8 upward, so that the debris and some cleaning water at the bottom of the first magnetic core tube 8 can be dried and baked through the upper air jet port 305 and the lower air jet port 306.

[0027] The welding mechanism 4 includes a third moving block 402 slidably connected to the upper surface of the welding table 1. A third threaded rod 401 is threadedly connected inside the third rotating rod 509. A third push rod 403 is slidably connected inside the upper end of the third moving block 402. One end of the third push rod 403 is fixedly connected to a third clamping block 405. A third spring 404 is sleeved on the outer surface of the third push rod 403. A third fixed base 406 is fixedly connected to the upper surface of the welding table 1. A placement table 407 is fixedly connected to the upper surface of the third fixed base 406. A gantry 408 is fixedly connected to the upper surface of the placement table 407. A moving telescopic rod 409 is slidably connected inside the gantry 408. The lower end of the moving telescopic rod 409 is fixedly connected to a fixed disk 410. A positioning rod 413 is fixedly connected to the lower end of the fixed disk 410.

A welding head 412 is fixedly connected inside the rotating disk 411.

[0028] Further, the welding mechanism 4 is used to weld the first magnetic core tube 8 and the second magnetic core tube 9 after grinding and cleaning. The motor 501 drives the third rotating rod 509 to rotate, and then the third threaded rod 401 pushes the third clamping block 405 to clamp and fix the first magnetic core tube 8. After placing the second magnetic core tube 9 above the placement table 407, the moving telescopic rod 409 drives the positioning rod 413 to insert into the second magnetic core tube 9 and then expand through the top block 414 to drive the second magnetic core tube 9 to move above the first magnetic core tube 8. Then, the positioning rod 413 is inserted into the hole inside the first magnetic core tube 8 to achieve the positioning function.

[0029] Working principle: After the first magnetic core tube 8 moves into the grinding and cleaning mechanism 2, the first rotating rod 507 is rotated by starting the motor 501. Then, the first threaded rod 206 pushes the first moving block 207 to move inward. Thus, the first moving block 207 compresses the first spring 209 to push the first clamping block 210 to move. The first clamping blocks 210 on both sides of the first magnetic core tube 8 move towards the middle simultaneously, which can clamp and fix the first magnetic core tube 8. Therefore, it can prevent the first magnetic core tube 8 from moving during the grinding of the first magnetic core tube 8. When the first magnetic core tube 8 after being ground by the grinding and cleaning mechanism 2 is conveyed to the drying mechanism 3 through the second conveyor belt 6, when clamping the first magnetic core tube 8 inside the drying mechanism 3, the first limiting rod 308 pushes the second moving block 309 to move towards the middle. When the second limiting rod 316 moves to the middle of the second limiting groove 315 and continues to move inside the second limiting groove 315, the second moving block 309 will move upward according to the shape of the first conveyor belt 513. Thus, it can lift the clamped first magnetic core tube 8 upward, so that the debris ground at the bottom of the first magnetic core tube 8 and some cleaning water can be dried and baked through the upper air jet 305 and the lower air jet 306. Then, it is continuously conveyed to the welding mechanism 4 through the second conveyor belt 6. The third rotating rod 509 is rotated by the motor 501, and then the third threaded rod 401 pushes the third clamping block 405 to clamp and fix the first magnetic core tube 8. After that, after placing the second magnetic core tube 9 above the placement table 407, the moving telescopic rod 409 drives the positioning rod 413 to insert into the second magnetic core tube 9 and then expands through the top block 414 to drive the second magnetic core tube 9 to move above the first magnetic core tube 8. Then, the positioning rod 413 is inserted into the hole inside the first magnetic core tube 8 to achieve the positioning function.
