[0002] In the production and manufacturing process of transformers, welding is a crucial link, and its welding quality directly affects the performance and service life of the transformer. Traditional transformer welding equipment mostly uses manual welding, which is not only inefficient, but also the welding quality is greatly affected by the workers' technical level and working status, making it difficult to ensure consistency.

When the transformer needs to be welded, it can be placed on the upper end of the placement table, and then the motor is started and the clamping mechanism is driven to clamp the transformer. Then the height of the transformer is adjusted by the electric cylinder, and the electric roller is driven to drive the rotating disk to rotate, thereby changing the angle of the transformer.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Among them, the clamping mechanism 7 includes a rotating shaft 71, a wave cam 72, a push rod 73, a fixed plate 74, a first hinge rod 75, a guide rod 76, a limit block 77, a first spring 78, a second hinge rod 79 and a fixed rod 710. The suction cup of the transformer that fits the side wall of the fixed plate 74 is placed in the four sets of clamping mechanisms 7. At this time, the first spring 78 is in a compressed state. The four sets of clamping mechanisms 7 clamp the transformer for fixing, so that the transformer can be directly welded on the operating table 1, avoiding the staff from welding by hand, reducing the possibility of accidents, and improving the accuracy of welding work. Avoid hand shaking during hand-held work and other situations that affect welding. The rotating shaft 71 passes through the clamp 6, and the penetration is rotatably connected. The wave cam 72 is fixedly connected to the right side of the rotating shaft 71 The outer wall of the wave cam 72 is provided with a wave groove. When the wave cam 72 rotates, the wave groove on the outer wall of the wave cam 72 also rotates with the wave cam 72. A rotating handle is fixed to the right side wall of the wave cam 72. When the partial welding is completed and the angle needs to be adjusted, the rotating handle can be rotated to drive the wave cam 72 to rotate. The rotation of the wave cam 72 drives the rotating shaft 71 to rotate. The push rod 73 passes through the clamp 6 and is slidably connected at the penetration point. A convex rod is fixed to the bottom surface of the push rod 73. The outer wall of the convex rod and the inner wall of the wave groove on the outer wall of the wave cam 72 are fitted together, and the fitting part is slidably connected. When the wave groove rotates, the convex rod fitted with its inner wall slides along the wave groove. When the convex rod slides to the leftmost end along the wave groove, the convex rod extends out of the clamp 6 When the locking cam 75 is in the state of being moved forward, the locking cam 73 is in the state of being moved forward, and the locking cam 73 is in the state of being moved forward, so that the locking cam 73 can be locked to the locking cam 73 by the locking cam 73a. Then, the upper surface of the limit block 77 is fixedly connected to the bottom end of the first spring 78, and the second hinge rod 79 rotates upward to push the limit block 77 to slide upward, further compressing the first spring 78. The top end of the first spring 78 is fixedly connected to the top end of the guide rod 76, and the side wall of the limit block 77 is hinged to one end of the second hinge rod 79, and the end of the second hinge rod 79 away from the limit block 77 is hinged to the long rod end of the first hinge rod 75. When the first hinge rod 75 rotates upward, it drives the second hinge rod 79 to rotate upward, so that the clamping mechanism 7 is released, and the fixing rod 710 is L-shaped. The bottom surface of the limit block 77 is hinged to the short rod end of the fixing rod 710. When the limit block 77 slides upward, it drives the short rod end of the fixing rod 710 to move upward, and the outer wall of the protrusion fixes the limit rod.The limiting rod passes through the long rod end of the fixing rod 710, and the penetration is slidably connected. The long rod end of the fixing rod 710 rotates around the limiting rod and slides along the long rod end of the fixing rod 710. The long rod end of the fixing rod 710 moves downward to press the transformer at the edge. When the clamping mechanism 7 rotates while clamping the transformer and adjusting the welding angle of the transformer, the wave groove on the outer wall of the wave cam 72 cooperates with the convex rod at the bottom end of the push rod 73 to drive the push rod 73 to interact forward, push the first hinged rod 75 just above to rotate, so that the first hinged rod 75 drives the second hinged rod 79 Loosen the clamping mechanism 7 above the transformer to prevent the top clamping mechanism 7 from blocking the welding area when adjusting to the required welding angle, affecting welding, and preventing the transformer from being removed and re-fixed, affecting welding efficiency; when loosening the top clamping mechanism 7, the second hinged rod 79 is rotated to drive the limit block 77 to slide upward, and the limit rod drives the fixed rod 710 to rotate, so that the fixed rod 710 presses the edge of the transformer from above, preventing the transformer from being overweight or shifting its center of gravity, and the transformer from tipping over and falling when the top clamping mechanism 7 is loosened, damaging the transformer.

[0030] When the present embodiment is working, the suction cup of the transformer that fits the side wall of the fixing plate 74 is placed in the four-group clamping mechanism 7. At this time, the first spring 78 is in a compressed state. The four-group clamping mechanism 7 clamps the transformer. The motor 3 is started. The motor 3 drives the screw rod 4 to rotate. When the screw rod 4 rotates, it drives the adjustment rod 5 to slide along the slide groove of the operating table 1. The position of the clamp 6 is adjusted, and the transformer is moved under the welder 2 for welding. When the partial welding is completed and the angle needs to be adjusted, the handle can be rotated to drive the wave cam 72 to rotate. The rotation of the wave cam 72 drives the rotating shaft 71 to rotate. The rotating shaft 71 The fixing plate 74 is driven to rotate. When the fixing plate 74 rotates, the four groups of clamping mechanisms 7 hinged on its outer wall also rotate together, driving the transformer to rotate. When the clamping mechanism 7 rotates, the wave groove on the outer wall of the wave cam 72 also rotates with the wave cam 72. When the wave groove rotates, the convex rod fitted with its inner wall slides along the wave groove. When the convex rod slides to the leftmost end along the wave groove, the ejector rod 73 extends out of the clamp 6, and at the same time, one group of the clamping mechanism 7 rotates to the top. At this time, the ejector rod 73 will push the first hinged rod 75 upward around the hinge with the convex block on the outer wall of the fixing plate 74. When the first hinge rod 75 rotates upward, the second hinge rod 79 is driven to rotate upward, so that the uppermost clamping mechanism 7 is released, and the second hinge rod 79 rotates upward to push the limit block 77 to slide upward, further compressing the first spring 78. When the limit block 77 slides upward, the short rod end of the fixing rod 710 is driven to move upward, and the long rod end of the fixing rod 710 rotates around the limit rod and slides along the long rod end of the fixing rod 710 at the same time. The long rod end of the fixing rod 710 moves downward and presses the transformer at the edge. The rotating shaft 71 continues to rotate. When the uppermost clamping mechanism 7 leaves the upper part, The wave groove on the outer wall of the wave cam 72 drives the push rod 73 to retract, and the first hinged rod 75 is no longer subjected to thrust. At the same time, the limit block 77 slides downward under the elastic force of the first spring 78, driving the second hinged rod 79 to rotate. The rotation of the second hinged rod 79 drives the first hinged rod 75 to rotate. The hinge between the first hinged rod 75 and the second hinged rod 79 clamps the transformer again. While the limit block 77 slides downward, it drives the short rod end of the fixed rod 710 to move downward, and the long rod end of the fixed rod 710 rotates around the limit rod and slides along the long rod end of the fixed rod 710, and the long rod end of the fixed rod 710 moves upward.

[0031] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, the clamping mechanism 7 is provided with a fixing mechanism 8 that makes the transformer and the clamp 6 fit more closely, and the fixing mechanism 8 includes a connecting rod 81, a telescopic rod 82, an air extraction rod 83, a gear 84, a top block 85, a friction block 86, a fixing plate 87 and a third spring 88. The connecting rod 81 is fixedly connected to the bottom surface of the limit block 77. When the limit block 77 slides upward, the connecting rod 81 is driven to move upward. The connecting rod 81 penetrates the telescopic rod 82 and is slidably connected at the penetration point. When the connecting rod 81 moves upward, the telescopic rod 82 is pulled to move upward. A second spring is fixed to the bottom end of the connecting rod 81. One end of the second spring away from the connecting rod 81 is fixedly connected to the inner wall of the telescopic rod 82. The elastic coefficient of the second spring is small. Due to the elastic coefficient of the first spring 78, the air extraction rod 83 penetrates the fixed plate 74 and is slidably connected at the penetration point. The air extraction rod 83 slides backward, which reduces the air density between the suction cup and the transformer. The pressure between the transformer and the suction cup is less than the pressure of the external air, so that the transformer fits more closely with the suction cup. A threaded groove is provided on the outer wall of the air extraction rod 83. The air extraction rod 83 penetrates the gear 84 and fits at the penetration point. A semicircular body is fixed on the inner wall of the gear 84. The outer wall of the semicircular body fits the threaded groove of the outer wall of the air extraction rod 83, and the fitting point is slidably connected. When the gear 84 rotates, the semicircular body on its inner wall slides along the threaded groove of the outer wall of the air extraction rod 83. The position of the gear 84 remains unchanged. Therefore, when the semicircular body slides along the threaded groove, it drives the air extraction rod 83 to slide backward, and the gear 84 The top block 85 is meshed with the telescopic rod 82, and the telescopic rod 82 drives the gear 84 to rotate when it moves upward. The rear end of the air pumping rod 83 is fixed with a top block 85. When the air pumping rod 83 slides backward, it drives the top block 85 to move backward. The friction block 86 penetrates the rotating shaft 71 and is slidably connected at the penetration point. When the top block 85 moves to contact the friction block 86, it pushes the friction block 86 to slide along the inclined surface in the direction away from the rotating shaft 71. When the top block 85 moves to the top, the end of the friction block 86 away from the rotating shaft 71 abuts against the inner wall of the clamp 6, increasing the friction force received by the rotating shaft 71 when the rotating shaft 71 rotates, limiting the rotating shaft 71, and the upper surface of the friction block 86 is fixed with a fixed plate 87, and the side wall of the fixed plate 87 is fixedly connected to one end of the third spring 88, and the end of the third spring 88 away from the fixed plate 87 and The outer wall of the rotating shaft 71 is fixedly connected. When the friction block 86 slides in the direction away from the rotating shaft 71, the third spring 88 is stretched. When the rotating shaft 71 continues to rotate, the air extraction rod 83 moves forward and drives the top block 85 to move forward. The friction block 86 is no longer pushed by the top block 85, and is at the same time affected by the elastic force of the third spring 88, so that the friction block 86 returns to its original position, and the limit of the friction block 86 on the rotating shaft 71 is released. The fixing mechanism 8 drives the connecting rod 81 to move through the sliding of the limit block 77, and at the same time cooperates with the linkage of the telescopic rod 82 and the gear 84 to drive the air extraction rod 83 to slide, and the air between the suction cup and the transformer is extracted, so that when the clamping mechanism 7 at the top of the transformer is released, the transformer can also be more stably fixed on the clamp 6, thereby further improving the stability of the device;When the air extraction rod 83 slides, the top block 85 is driven to move, pushing the friction block 86 against the inner wall of the clamp 6, increasing the friction between the shaft 71 and the clamp 6, and avoiding the situation that the transformer vibrates during welding and drives the shaft 71 to rotate, causing the adjusted angle of the transformer to be changed again, affecting the quality of welding.

[0032] The fixture 6 is provided with a knocking mechanism 9 for cleaning iron filings when rotating. The knocking mechanism 9 includes a square plate 91, a connecting rod 92 and a knocking rod 93. The rotating shaft 71 passes through the square plate 91 and is fixedly connected at the penetration point. The outer wall of the friction block 86 is fixed with a connecting rod 92. When the friction block 86 slides, the connecting rod 92 is driven to move. The outer wall of the square plate 91 and the upper end of the knocking rod 93 are hinged. The connecting rod 92 passes through the knocking rod 93 and is slidably connected at the penetration point. The movement of the connecting rod 92 drives the knocking rod 93 to rotate around the hinge with the square plate 91. When the friction block 86 is released from the limit, the friction block 86 The third spring 88 quickly resets itself due to the elastic force, driving the connecting rod 92 to move quickly. The connecting rod 92 drives the knocking rod 93 to rotate quickly, causing the knocking rod 93 to hit the rotating shaft 71. The knocking mechanism 9 drives the knocking rod 93 to rotate quickly through the sliding of the friction block 86, causing the knocking rod 93 to hit the rotating shaft 71, causing the rotating shaft 71 to vibrate, driving the transformer to vibrate. After the welding work is completed, or before the angle needs to be adjusted for the next welding step, the debris generated during the welding is shaken off to avoid affecting the next welding or subsequent work and affecting the quality of transformer production.

[0033] When the embodiment is working, when the limit block 77 slides upward, it drives the connecting rod 81 to move upward. When the connecting rod 81 moves upward, it pulls the telescopic rod 82 to move upward. When the telescopic rod 82 moves upward, it drives the gear 84 to rotate. When the gear 84 rotates, it drives the telescopic rod 82 meshed on the other three sides to move. Since the telescopic rod 82 and the connecting rod 81 are connected by a second spring, and the elastic coefficient of the second spring is much smaller than the elastic coefficient of the first spring 78, the second spring is compressed when the telescopic rod 82 on the other three sides moves, and the connecting rod 81 is not pushed to move. When the gear 84 rotates, the semicircular body on its inner wall slides along the thread groove on the outer wall of the suction rod 83, and the position of the gear 84 remains unchanged. Therefore, when the semicircular body slides along the thread groove, it drives the suction rod 83 to slide backward, so that the air density between the suction cup and the transformer becomes smaller. When the suction rod 83 slides backward, it drives the top block 85 to move backward. When the top block 85 moves to contact the friction block 86, it pushes the friction block 86 along When the second spring is compressed to the maximum extent, the elastic force of the second spring pushes the telescopic rod 82 to move downward, and the telescopic rod 82 drives the gear 84 to rotate, and the gear 84 drives the semicircular body to rotate, so that the suction rod 83 slides forward, and the pressure between the transformer and the suction cup is restored. When the suction rod 83 moves forward, it drives the top block 85 to move forward, and the friction block 86 is no longer pushed by the top block 85, and at the same time, it is affected by the elastic force of the third spring 88, so that the friction block 86 returns to its original position, and the limit of the friction block 86 on the rotation shaft 71 is released.

[0034] When the friction block 86 slides outwardly away from the rotating shaft 71, the connecting rod 92 on its outer wall drives the knocking rod 93 to rotate around the hinge between the knocking rod 93 and the square plate 91, so that the end of the knocking rod 93 away from the square plate 91 is away from the rotating shaft 71. When the friction block 86 is released from the limit, the friction block 86 is quickly reset by the elastic force of the third spring 88, driving the connecting rod 92 to move quickly, and the connecting rod 92 drives the knocking rod 93 to rotate quickly, so that the knocking rod 93 hits the rotating shaft 71.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
