[0002] The lead-out pole is a common type of pole in power lines. It is mainly used at the starting point, end point or branch of the line, and is responsible for leading out or introducing wires.

[0003] The outlet poles of transformer rectifiers often do not need to be replaced frequently and will be used continuously for several years or even longer. Therefore, most outlet poles are usually welded to brackets and connected to the transformer rectifier through the brackets. The outlet poles include a main pole and an insulator. When welding, the main pole is usually welded to the bracket, and the welding area is at the bottom of the main pole. However, if the welding area at the bottom of the main pole is not smooth and has bumps, it will easily cause a cold weld during welding. This will cause the outlet pole to be easily corroded by rainwater outdoors and break at the connection between the outlet pole and the bracket. Therefore, the present application proposes a clamping device for welding the outlet pole of a transformer rectifier and its preparation process, which can grind and wipe the bottom of the main pole, grind the welding area of ​​the main pole smooth and wipe off the burrs and dust on the main pole before welding the main pole, so as to avoid the situation where the weld formed between the main pole and the bracket has different strengths due to the unevenness.

[0036] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0037] like Figures 1-6 As shown, an embodiment of the present invention provides a clamping device for welding a transformer rectifier lead-out rod, comprising a frame 1, a moving device 2, a moving frame 3, a lead-out rod body 5, and a welding base plate 17. The moving device 2 is installed on the frame 1, and the moving frame 3 is connected to the moving device 2 for driving the moving frame 3 to move. The moving device 2 can drive the moving frame 3 to move along the operating table 6, and can cover the grinding area 601, the wiping area 602, and the welding area 603 on the operating table 6. The lead-out rod body 5 includes a middle main rod and an insulator thereon. The lead-out rod body 5 is fixed to the welding base plate 17 by welding. During specific welding, the main rod is welded to the welding base plate 17.

[0038] In order to clamp the wire-out rod body 5 , a clamping mechanism 4 for clamping and releasing the wire-out rod body 5 is provided on the movable frame 3 .

[0039] In a specific embodiment, the clamping mechanism 4 includes a clamping frame 401, a threaded rod 402, a drive motor 403, a pull-out plate 404, a clamping claw support 405, a welding clamping claw 406, a connecting plate 407, and an upper pressure plate 408. The clamping frame 401 is installed on the mobile frame 3, the threaded rod 402 is movably connected to the clamping frame 401, the threaded rod 402 is connected to the output shaft of the drive motor 403 through a coupling, the threaded rod 402 is connected to the pull-out plate 404 through a threaded connection, and the pull-out plate 404 is connected to the clamping claw 406 through a threaded connection. The plate 404 is slidably matched with the clamping frame 401, the clamping jaw support 405 is installed on the clamping frame 401, the clamping jaw support 405 is movably connected to the welding clamping jaw 406, the welding clamping jaw 406 is movably connected to one end of the connecting plate 407, and the other end of the connecting plate 407 is movably connected to the pulling plate 404. An upper pressure plate 408 is provided on the upper side of the welding clamping jaw 406. There are two welding clamping jaws 406, and the two welding clamping jaws 406 are symmetrically distributed about the center line of the threaded rod 402.

[0040] When the driving motor 403 is started, the threaded rod 402 can be driven to rotate. The pulling plate 404 connected to the threaded rod 402 by a thread can move along the clamping frame 401 as the threaded rod 402 rotates. During the movement, the welding clamping jaw 406 is pulled to rotate around the clamping jaw support 405 by the connecting plate 407. The two welding clamping jaws 406 move closer to or away from each other, and can clamp or release the wire rod body 5 located between the two welding clamping jaws 406. The upper pressure plate 408 provided on the upper side of the welding clamping jaw 406 can clamp the insulator in the wire rod body 5. At the same time, the welding clamping jaw 406 and the upper pressure plate 408 are provided with a first arc portion and a second arc portion corresponding to the main rod and the insulator. In this way, when the welding clamping jaw 406 and the upper pressure plate 408 clamp the wire rod body 5 on the upper and lower sides at the same time, the wire rod body 5 can be vertically distributed, which is convenient for subsequent grinding, wiping and welding work.

[0041] In order to move the outlet rod body 5 clamped by the clamping mechanism 4 to the welding position and perform grinding and wiping work at the welding position before welding, an operating table 6 is provided on the outside of the frame 1, and a grinding area 601, a wiping area 602 and a welding area 603 are provided on the operating table 6.

[0042] In a specific embodiment, a grinding guide tube 7, a support seat 8, and a grinding mechanism are provided at the grinding area 601. The guide hole in the grinding guide tube 7 cooperates with the main rod in the outlet rod body 5. A tapered tube is provided at the top of the grinding guide tube 7, and the tapered hole in the tapered tube communicates with the guide hole. The grinding mechanism is used to grind the bottom of the outlet rod body 5 inserted into the grinding guide tube 7. When the outlet rod body 5 is welded to the welding base plate 17, the welding area is at the bottom of the outlet rod body 5, which is also the bottom of the main rod. The grinding guide tube 7 is mounted on the operating table 6 via the support seat 8.

[0043] More specifically, the grinding mechanism includes a first grinding gear 9, a second grinding gear 10, a grinding motor, a grinding head 11, a grinding base plate 12, and a first lifting device 13. The center line of the first grinding gear 9 coincides with the center line of the grinding guide tube 7. The first grinding gear 9 is connected to the second grinding gear 10 through tooth meshing transmission. The second grinding gear 10 is connected to the output shaft of the grinding motor, and can be specifically connected through common flat keys and keyways. The first grinding gear 9 is movably connected to the operating table 6. The first grinding gear 9 can rotate on the operating table 6. The center of rotation during rotation is the center line of the grinding guide tube 7. The grinding head 11 is installed on the first grinding gear 9. The grinding base plate 12 is connected to the first lifting device 13 for driving the grinding base plate 12 up and down. The size of the grinding base plate 12 is smaller than the size of the guide hole in the grinding guide tube 7. The first lifting device 13 can use a cylinder.

[0044] After the clamping mechanism 4 clamps the outlet rod body 5, the mobile frame 3 and the clamping mechanism 4 are moved to the position of the grinding area 601 through the moving device 2, and then the clamping mechanism 4 is controlled to loosen the outlet rod body 5. The loosened outlet rod body 5 falls and is inserted into the grinding guide tube 7, and finally falls on the grinding base plate 12. At this time, the clamping mechanism 4 is controlled to clamp the outlet rod body 5. At this time, due to the falling of the outlet rod body 5, the welding clamping claw 406 clamps the insulator on the outlet rod body 5. At this time, the grinding motor is started, and the grinding motor can drive the second grinding gear 10 to rotate. The second grinding gear 10 can drive the first grinding gear 9 to rotate through the tooth transmission meshing engagement, and the first grinding gear 9 can drive the grinding head 11 to rotate, and the grinding surface of the grinding head 11 is in contact with the bottom of the outlet rod body 5. The grinding head 11 rotates several circles to grind the area of ​​the bottom of the outlet rod body 5 that needs to be welded smooth. The setting of the first lifting device 13 can push out the loosened outlet rod body 5 after the outlet rod body 5 is ground, so that the outlet rod body 5 reaches the area above the grinding guide tube 7. In this way, there is no need to manually pull out the outlet rod body 5, which facilitates the control of the subsequent movement of the outlet rod body 5.

[0045] The setting of the grinding base plate 12 allows the outlet rod body 5 to still be at a certain height from the operating table 6 when it falls on the upper side of the grinding base plate 12, and the area covered by the grinding head 11 can be lower than the height of the outlet rod body 5, so that the bottom of the outlet rod body 5 can be polished cleanly without leaving any dead corners.

[0046] In order to wipe the area where the wire-outlet rod body 5 and the welding base plate 17 are welded, and to remove iron filings remaining due to grinding, as well as dust on the wire-outlet rod body 5, a wiping guide sleeve 14 and a wiping mechanism 15 are provided at the position of the wiping area 602. The wiping guide sleeve 14 is installed on the operating table 6, and the wiping mechanism 15 is installed on the operating table 6. The wiping mechanism 15 is used to wipe the bottom of the wire-outlet rod body 5 that needs to be welded. The wiping mechanism 15 is internally provided with a first wiping gear, a second wiping gear, a wiping power motor, a wiping base plate, a second lifting device, and a wiping cloth. The components in the wiping mechanism 15 and the grinding mechanism are replaceable. The grinding head 11 in the grinding mechanism corresponds to the wiping cloth. The wiping cloth can wipe the bottom of the wire-outlet rod body 5 during rotation, so that the bottom of the main rod in the wire-outlet rod body 5 can be kept clean, which is convenient for subsequent welding work.

[0047] In order to weld the wire-out rod body 5, a welding guide mechanism 16 is provided at the position of the welding area 603. The welding guide mechanism 16 cooperates with the main rod in the wire-out rod body 5, and the welding work between the wire-out rod body 5 and the welding base plate 17 is performed in the welding area 603. After the wire-out rod body 5 and the welding base plate 17 are welded together, the wire-out rod body 5 cannot be pulled out from the welding guide mechanism 16 from the upper side.

[0048] Therefore, the welding guide mechanism 16 includes a first connecting sleeve 1601 and a second connecting sleeve 1602, which are connected by bolts. The first connecting sleeve 1601 and the second connecting sleeve 1602 can be separated, so that the welded outlet rod body 5 can be removed from the welding guide mechanism 16.

[0049] A welding preparation process for a transformer rectifier outlet rod comprises the following steps:

[0050] Step 1: Clamp the outlet rod body 5; start the clamping mechanism 4 to clamp the main rod and insulator in the outlet rod body 5;

[0051] Step 2: Grind the welding area 603 of the outlet rod body 5; start the moving device 2, move the moving frame 3, the clamping mechanism 4, and the clamped outlet rod body 5 to the position of the grinding area 601, and the clamping mechanism 4 releases the outlet rod body 5, and the outlet rod body 5 falls and is inserted into the grinding guide tube 7. Start the grinding mechanism to grind the welding area 603 at the bottom of the outlet rod body 5 until it is smooth. After grinding, the outlet rod body 5 is pushed out of the grinding guide tube 7 by the first lifting device 13, and the outlet rod body 5 is clamped by the clamping mechanism 4;

[0052] Step 3: Wipe the welding area 603 of the outlet rod body 5; start the moving device 2 to move the moving frame 3, the clamping mechanism 4, and the clamped outlet rod body 5 from the grinding area 601 to the position of the wiping area 602, the clamping mechanism 4 loosens the outlet rod body 5, and the outlet rod body 5 falls and is inserted into the wiping guide sleeve 14. The wiping mechanism 15 is started to wipe the area on the bottom of the outlet rod body 5 that needs to be welded. The second lifting device lifts the outlet rod body 5, and then the clamping mechanism 4 clamps the outlet rod body 5 pushed out of the wiping guide sleeve 14;

[0053] Step 4: Insert the outlet rod body 5 into the corresponding position on the welding base plate 17. Activate the moving device 2 to move the moving frame 3, the clamping mechanism 4, and the clamped outlet rod body 5 from the wiping area 602 to the welding area 603. The clamping mechanism 4 releases the outlet rod body 5, and the outlet rod body 5 falls along the welding guide mechanism 16 to the position on the welding base plate 17 where welding is required. After alignment, proceed with subsequent welding work.
