Description

Technical Field

[0001] The invention relates to the technical field of transformer core production, in particular to a welding device for transformer core production. Background Art

[0002] The transformer core is the main magnetic circuit part of the transformer, usually made of stacked silicon steel sheets. The core has a significant impact on the power transmission of the transformer. Common transformer cores are produced by welding two E-shaped cores. However, existing transformer core welding equipment still has certain defects, such as:

[0003] The "transformer core integral welding device" with application number CN201520792687.7 does not have a flipping function during use. After welding one side of the transformer core, it needs to be manually re-clamped and then welded on the other side. This is not only cumbersome and inconvenient to operate, but also has low efficiency in welding the transformer core. At the same time, the smoke generated during the welding process cannot be absorbed, causing the smoke to affect the processing environment and endanger the health of workers, thus having limitations in use.

[0004] In view of this, in order to solve the above problems, an in-depth study was conducted and a welding device for transformer core production was proposed. Summary of the Invention

[0018] As a preferred technical solution of the present invention, the second driving mechanism includes a second motor, which is fixedly mounted on the left inner wall of the box, and the box is fixedly mounted on the upper end of the left wall of the fixed frame.

[0019] By adopting the above technical solution, the movable plate drives the support plate to move back and forth through the rotation of the reciprocating screw, thereby ensuring that the welding gun moves back and forth synchronously.

[0021] By adopting the above technical solution, when the reciprocating screw rotates, the driving gear and the driven gear are arranged to drive the rotating shaft and the fan to rotate, thereby sucking in and discharging the smoke and dust.

[0022] As a preferred technical solution of the present invention, the linkage mechanism includes a sliding rod, which slides horizontally and passes through the fixed plate, and a linkage rod is fixedly installed on the right end of the sliding rod, a rack is fixedly installed on the bottom end of the linkage rod, and the bottom of the rack is meshed with a linkage gear, the linkage gear is fixedly sleeved on the surface of the rotating rod, and the front and rear ends of the rotating rod are both connected to the mounting plate with bearings, and the mounting plate is fixedly installed on the top surface of the workbench.

[0023] The above technical solution is adopted to facilitate the support plate to move to the right to contact the linkage rod, so that the linkage rod drives the rack to move to the right and drives the rotating rod to rotate through the linkage gear.

[0024] As a preferred technical solution of the present invention, the return mechanism includes a side plate, which is fixedly installed on the left end of the sliding rod, and a spring is provided on the outer side of the sliding rod, and the left end of the spring is fixedly connected to the right side of the side plate, and the right end of the spring is fixedly connected to the left side of the fixed plate.

[0025] By adopting the above technical solution, the setting of the spring can ensure that the linkage rod can be reset to the left.

[0026] As a preferred technical solution of the present invention, the flipping mechanism includes a hollow tube, which is sleeved on the outer side of the rotating rod, and two hollow tubes are symmetrically arranged, the inner wall surface of the hollow tube is provided with a slide groove, and the inside of the slide groove is slidably connected to a slide rail, and the slide rail is fixedly installed on the surface of the rotating rod, the outer side of the hollow tube is sleeved with a connecting plate, and the hollow tube is connected to the connecting plate bearing, the left side of the connecting plate is fixedly installed with a connecting rod, and the left side of the connecting rod is fixedly connected to the right side of the skateboard, the outer wall surface of the hollow tube is fixedly sleeved with a driving pulley, and the driving pulley is connected to the driven pulley through a belt drive, and the driven pulley is coaxially fixedly installed on the outer end of the mounting shaft.

[0027] The above technical solution makes it easy to drive the hollow tube to rotate through the setting of the slide rail and the slide groove when the rotating rod rotates, and drive the installation shaft and the clamping seat to rotate synchronously through the setting of the active pulley, belt and driven pulley, so as to realize the flipping of the clamped transformer core.

[0028] As a preferred technical solution of the present invention, the limiting mechanism includes a limiting rod, which slides longitudinally through the horizontal plate, and the bottom surface of the limiting rod and the top surface of the linkage rod are matching inclined surfaces, and a connecting frame is fixedly installed on the top surface of the limiting rod, and a tension spring is sleeved on the outside of the limiting rod, and the top end of the tension spring is fixedly connected to the bottom surface of the connecting frame, and the bottom end of the tension spring is fixedly connected to the bottom surface of the horizontal plate.

[0029] By adopting the above technical solution, the linkage rod can contact the limit rod to move the limit rod upward. After the linkage rod is separated from the limit rod to the right, the limit rod moves downward to limit the linkage rod.

[0030] As a preferred technical solution of the present invention, the reset mechanism includes a straight rod, which is fixedly installed on the right side of the movable plate, and the straight rod slides horizontally through the fixed plate, and a push block is fixedly installed on the right end of the straight rod, the straight rod movably passes through the interior of the connecting frame, and a resistance block is fixedly installed on the inner top surface of the connecting frame, and the bottom surface of the resistance block and the top left end surface of the push block are matching inclined surfaces.

[0031] By adopting the above technical solution, after the straight rod drives the push block to move leftward and abuts against the abutment block, the connecting frame drives the limit rod to move upward and separate from the linkage rod, so that the linkage rod returns to the left.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows: the welding device for transformer core production can ensure that after welding one side of the transformer core is completed, it can be turned over so that welding can be carried out on the other side of the transformer core. The operation is simple and flexible, and the welding efficiency of the transformer core is improved. At the same time, the smoke and dust generated during the welding production of the transformer core can be absorbed, thereby ensuring the air quality of the transformer core production environment and avoiding harm to the health of workers.

[0033] 1. The first motor drives the bidirectional screw to rotate, causing the two slides to move toward each other, thereby causing the mounting shaft and the clamping seat to move synchronously to clamp and fix the transformer core;

[0034] 2. The reciprocating screw is driven by the second motor to rotate, so that the movable plate drives the support plate, the electric telescopic rod and the welding gun to move back and forth. When the welding gun moves to the right, one side of the transformer core is welded by the welding gun;

[0035] 3. After the support plate moves to the right and hits the linkage rod, the linkage rod will move to the right, causing the rack to move to the right and drive the rotating rod to rotate through the linkage gear, thereby driving the hollow tube to rotate through the action of the slide rail and the slide groove. The rotation of the hollow tube drives the mounting shaft and the clamping seat to rotate synchronously through the active pulley, the belt and the driven pulley, so that the transformer core rotates at the same time, until the linkage rod hits the limit rod, causing the limit rod to move upward and stretch the tension spring through the connecting frame. After the linkage rod moves to the right and separates from the limit rod, the limit rod moves downward under the action of the tension spring to limit the linkage rod, and the transformer core is flipped at this time;

[0036] 4. When the movable plate moves to the left, the turned transformer core is welded by the welding gun, thereby achieving welding on both sides of the transformer core and improving welding efficiency;

[0037] 5. The movable plate continues to move to the left, causing the push block driven by the support rod to contact the resistance block, pushing the resistance block, the connecting frame and the limit rod to move upward. After the limit rod moves upward and separates from the linkage rod, the spring releases the sliding rod to drive the linkage rod to move back to the left, thereby realizing the flip reset of the clamping seat;

[0038] 6. While the reciprocating screw is rotating, the driving gear and the driven gear cause the rotating shaft to drive the fan to rotate, so that the smoke generated during welding is absorbed by the suction hood, enters the cylinder through the through pipe and the telescopic hose, and is then discharged to the external purification equipment through the exhaust pipe.

[0064] The limiting mechanism includes a limiting rod 42, which slides longitudinally through the horizontal plate 41, and the bottom surface of the limiting rod 42 is an inclined surface that matches the top surface of the linkage rod 28. A connecting frame 43 is fixedly mounted on the top surface of the limiting rod 42, and a tension spring 44 is sleeved on the outside of the limiting rod 42, and the top end of the tension spring 44 is fixedly connected to the bottom surface of the connecting frame 43, and the bottom end of the tension spring 44 is fixedly connected to the bottom surface of the horizontal plate 41;

[0065] The reset mechanism includes a straight rod 45, which is fixedly mounted on the right side of the movable plate 6, and the straight rod 45 slides horizontally through the fixed plate 22, and a push block 46 is fixedly mounted on the right end of the straight rod 45, and the straight rod 45 movably passes through the interior of the connecting frame 43, and a resistance block 8 is fixedly mounted on the inner top surface of the connecting frame 43, and the bottom surface of the resistance block 8 and the top left end surface of the push block 46 are matching inclined surfaces.

[0066] Working principle: When in use, the first motor 16 is started to rotate the bidirectional screw rod 17, so that the two slides 3 move toward each other, thereby causing the slides 3 to drive the mounting shaft 4 and the clamping seat 5 to move synchronously, thereby clamping and fixing the transformer core;

[0067] As the slide plate 3 moves, the connecting rod 37 drives the connecting plate 36 and the hollow tube 33 to move synchronously, so that the slide rail 35 slides relative to the slide groove 34;

[0068] Then, the second motor 20 is started to rotate the reciprocating screw 19, firstly, the movable plate 6 drives the support plate 7, the electric telescopic rod 15 and the welding gun 9 to move to the right, and the transformer core is welded by the welding gun 9;

[0069] When the movable plate 6 and the support plate 7 move to the right, the movable plate 6 drives the straight rod 45 and the push block 46 to move to the right. The rightward movement of the support plate 7 will contact the linkage rod 28, so that the linkage rod 28 is pushed to move to the right, and the slide bar 27 drives the side plate 47 to move to the right to compress the spring 48. At the same time, the linkage rod 28 moves to the right and drives the rack 29 to move synchronously, so that the linkage gear 30 meshing with the rack 29 drives the rotating rod 31 to rotate, and the relative limit of the slide rail 35 and the slide groove 34 drives the hollow tube 33 to rotate synchronously, thereby driving the mounting shaft 4, the clamping seat 5 and the transformer core to rotate synchronously through the action of the driving pulley 38, the belt 39 and the driven pulley 40.

[0070] After the linkage rod 28 moves to the right and contacts the limit rod 42, it pushes the limit rod 42 upward, causing the connecting frame 43 to move upward synchronously to stretch the tension spring 44. After the linkage rod 28 moves to the right and separates from the limit rod 42, the tension spring 44 pulls the connecting frame 43 to drive the limit rod 42 downward, causing the limit rod 42 to limit and fix the linkage rod 28. At this time, the position of the linkage rod 28 causes the clamping seat 5 and the clamped transformer core to flip 180 degrees.

[0071] Then, when the reciprocating screw 19 continues to rotate, the moving plate 6 drives the support plate 7, the electric telescopic rod 15 and the welding gun 9 to move to the left, and the welding gun 9 is used to weld the other side of the transformer core;

[0072] The movable plate 6 moves leftward, causing the straight rod 45 and the push block 46 to move leftward, until the push block 46 contacts the contact block 8, pushing the contact block 8 upward, thereby causing the connecting frame 43 to drive the limiting rod 42 to move upward. After the limiting rod 42 moves upward and separates from the linkage rod 28, the spring 48 releases the side plate 47 to drive the sliding rod 27 and the linkage rod 28 to return to their original position. The return movement of the linkage rod 28 will cause the clamping seat 5 to return to its original position and flip over for subsequent use.

[0073] As the reciprocating screw 19 rotates, it drives the driving gear 23 to rotate, so that the driven gear 24 meshing with the driving gear 23 drives the rotating shaft 25 and the fan 26 to rotate synchronously, so that the smoke generated during welding is sucked into the through pipe 12 through the suction hood 13, and enters the cylinder 10 through the telescopic hose 11, and then discharged through the exhaust pipe 14. The exhaust pipe 14 is externally connected to an air purification device to achieve smoke treatment.
