The two adjustment racks are respectively meshed with the two adjustment gears, and the lower part of the adjustment rack is vertically slidably connected to the top of the welding support.

[0020] A method for using a welding device for transformer production comprises the following steps:

[0021] S1. When in use, the transformer housing is clamped by the positioning telescopic cylinder and the clamping plate. At the same time, the heat sink inside the storage box moves to the position of the discharge slot under the pressure of the push block and the push spring. When the heat sink moves to the limit position at the discharge slot, the heat sink at the rightmost position of the storage box extends from the inside of the discharge slot under the action of the guide inclined plate. Then the positioning motor is started to rotate the positioning screw rod, so that the positioning screw sleeve moves with the slide rod and the clamping sleeve toward the transformer housing.

[0022] S2. During the movement of the jacket, the positioning pin on the jacket cooperates and slides with the positioning groove on the inner wall of the adjusting sleeve, so that the jacket enters the position of the discharge slot and presses against the adjacent heat sink to move to the left. At this time, the heat sink on the left side of the storage box is separated from the heat sink in the extended state. During this process, the middle part of the jacket is in the same straight line as the middle part of the heat sink in the extended state, and the two clamping blocks are respectively located on both sides of the heat sink in the extended state. As the jacket continues to move, the T-shaped movable rod on the jacket cooperates and slides with the side wall of the trapezoidal guide block on the inner wall of the adjusting sleeve, so that the T-shaped movable rod is pressed and moves toward the middle direction of the jacket with the adjacent clamping blocks. At this time, with the cooperation of the hinged bar, the two clamping blocks move relative to each other to clamp the heat sink in the extended state and move toward the welding port on the surface of the transformer housing;

[0023] S3. When the clamped heat sink moves to the limit position with the jacket, the heat sink and the welding port of the transformer are plugged in. At this time, the transmission screw is started to rotate and the two welding heads move back to back to perform welding operations on the two ends of the heat sink. When the transmission screw sleeve on the upper part of the welding machine bracket and the welding head rise to the limit position, the upper transmission screw sleeve with the L-shaped slider presses the gasket on the vertical rod to rise. At this time, the gasket brings the vertical rod and the dislocation block to rise inside the sink, so that the dislocation block and the trapezoidal guide block are offset. At this time, the T-shaped movable rod is no longer pressed by the dislocation block, and resets and moves under the action of the reset spring, so that the two clamping blocks inside the jacket move back to back and release the clamping of the welded heat sink;

[0024] S4, then start the positioning motor to reverse the positioning screw rod, so that the jacket and the clamping block are reset and moved. When the jacket is moved out of the discharge slot position, the push block inside the storage box pushes the next heat sink to the discharge slot position again, and automatically replenishes the heat sink to the position to be welded;

[0025] S5. When the clamping sleeve brings the pressure rod back to the extreme position, the end of the pressure rod presses against the inclined surface of the side wall of the wedge plate, so that the wedge plate is pressed and moves the adjusting rack downward. At this time, the adjusting rack is engaged with the adjusting gear on the surface of the adjusting screw rod, and the adjusting gear and the one-way bearing cooperate to drive the adjusting screw rod to rotate. At this time, the adjusting screw sleeve drives the material storage box to translate on the surface of the adjusting screw rod, and automatically moves the heat sink to be welded on the material storage box to the next welding port position.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In the present invention, through the coordinated use of components such as the material storage box, the adjustment sleeve and the positioning mechanism, when welding the heat sink on the surface of the transformer shell, after the material storage box is moved to the next welding port position on the transformer surface, under the action of the positioning mechanism, the heat sink on the far right inside the material storage box automatically extends out and is clamped and plugged into the welding position through two clamping plates, thereby avoiding the operator placing the heat sink on the clamp and improving the convenience of operation.

[0028] In the present invention, through the coordinated use of components such as a material storage box, a positioning mechanism and an adjusting mechanism, when a heat sink on the surface of the transformer shell is welded, the pressure rod on the positioning mechanism and the wedge plate on the adjusting mechanism slide in coordination, so that the material storage box automatically moves to the next welding port position at a fixed distance, thereby improving work efficiency.

[0029] In the present invention, by using the vertical rod, the gasket and the L-shaped slider in coordination, when the welding operation of the welding machine head is completed, the rising L-shaped slider moves upward synchronously with the gasket and the vertical rod, so that the dislocation block at the bottom of the vertical rod rises and releases the contact with the T-shaped movable rod. At this time, the reset spring resets the T-shaped movable rod, so that the two clamping blocks automatically release the clamping of the heat sink, which is convenient to use.

[0046] A positioning telescopic cylinder 8 is symmetrically fixedly connected to the middle position of the top of the welding support 1, and a clamping plate 9 is fixedly connected to the movable end of the positioning telescopic cylinder 8. It should be noted that the positioning telescopic cylinder 8 is set as an electric telescopic cylinder, and the transformer housing is clamped by the positioning telescopic cylinder 8 and the clamping plate 9, and then the heat dissipation plates on the front and rear sides of the transformer housing are welded by the positioning mechanism 5 and the adjustment mechanism 7 at the front and rear sides of the welding support 1.

[0047] In this embodiment, Figures 1 to 12 As shown, the positioning mechanism 5 includes a push block 501, which is slidably connected to the inside of the material storage box 3, and a push spring 502 is fixedly connected between the side wall of the push block 501 and the inner wall of the material storage box 3. A discharge groove 503 is provided on the side of the material storage box 3 away from the push block 501, and a material guide inclined plate 504 is symmetrically fixedly connected to the position of the inner wall of the material storage box 3 near the discharge groove 503; the two material guide inclined plates 504 are symmetrically arranged on the inner wall of the material storage box 3 up and down. It should be noted that the outlet end width of the discharge slot 503 is set to 1.5 times the width of the heat sink, and the width of the guide ramp 504 is set to 0.5 times the width of the heat sink. When the heat sink moves toward the discharge slot 503 inside the storage box 3, the heat sink is pressed against the surface of the guide ramp 504, and then the heat sink moves obliquely toward the outlet end of the discharge slot 503 and extends out, and then the heat sink is still restricted inside the storage box 3 and will not move out of the discharge slot 503.

[0048] The inner wall of the adjusting sleeve 4 is rotatably connected with a positioning screw 505, the surface of the positioning screw 505 is threadedly connected with a positioning screw sleeve 506, the side wall of the adjusting sleeve 4 is fixedly connected with a positioning motor 507 matched with the positioning screw 505, the left side of the positioning screw sleeve 506 is symmetrically fixedly connected with a slide bar 508, a jacket 509 is slidably connected between the two slide bars 508, and the right side of the jacket 509 is slidably connected to the inside of the adjusting sleeve 4. It should be noted that the rotating end of the positioning motor 507 penetrates the adjusting sleeve 4 and is fixedly connected to the end of the positioning screw 505, and the left side of the adjusting sleeve 4 is open to facilitate the sliding of the jacket 509 inside the adjusting sleeve 4.

[0049] The top and bottom of the inner wall of the adjustment sleeve 4 are provided with positioning grooves 510, and the top and bottom of the right side of the jacket 509 are fixedly connected with positioning pins 511, and the two positioning pins 511 are respectively slidably connected to the inside of the two positioning grooves 510, and the middle part of the jacket 509 is rotatably connected with a hinge strip 512, and both sides of the inner wall of the jacket 509 are slidably connected with clamping blocks 513, and the surfaces of the two clamping blocks 513 are provided with grooves 514, and the two ends of the hinge strip 512 are respectively movably connected to the inside of the two grooves 514. It should be noted that: sliding holes are symmetrically opened on the side walls of the jacket 509, and the jacket 509 slides in cooperation with the slide rod 508 through the sliding holes; when the positioning screw 505 rotates to transmit the positioning screw sleeve 506, the positioning screw sleeve 506 translates the jacket 509 inside the adjustment sleeve 4 through the slide rod 508, and the jacket 509 moves along the trajectory of the positioning groove 510 through the positioning pin 511, and at this time the jacket 509 can slide on the surface of the slide rod 508.

[0050] A pressure rod 515 cooperating with the adjustment mechanism 7 is fixedly connected to the side of the jacket 509 away from the storage box 3, and a movable groove 516 is opened on the side of the jacket 509 close to the adjustment sleeve 4. A T-shaped movable rod 517 is slidably connected inside the movable groove 516. The left end of the T-shaped movable rod 517 extends to the inside of the jacket 509 and is fixedly connected to the side wall of the adjacent clamping block 513. A return spring 518 is movably connected between the middle part of the T-shaped movable rod 517 and the inner wall of the movable groove 516, and a trapezoidal guide block 519 cooperating with the T-shaped movable rod 517 is fixedly connected to the upper part of the inner wall of the adjustment sleeve 4. It should be noted that: when the jacket 509 slides inside the adjustment sleeve 4, the T-shaped movable rod 517 on the jacket 509 contacts the side wall of the trapezoidal guide block 519, so that the T-shaped movable rod 517 is pressed to move the corresponding clamping block 513. At this time, under the action of the hinge strip 512, the two clamping blocks 513 can move relative to each other to clamp the heat sink and transport it toward the transformer housing.

[0051] A sink 520 is provided on the inner wall of the adjustment sleeve 4 at one side away from the T-shaped movable rod 517, and a dislocation block 521 cooperating with the trapezoidal guide block 519 is slidably connected inside the sink 520, and a vertical rod 522 is fixedly connected to the top of the dislocation block 521, and a gasket 523 is fixedly connected to the top of the vertical rod 522 penetrating the adjustment sleeve 4. It should be noted that the sink 520 is provided at the upper position of the inner wall of the adjustment sleeve 4, and when the dislocation block 521 moves down to the limit, the side wall of the dislocation block 521 cooperates with the side wall of the trapezoidal guide block 519 to press the T-shaped movable rod 517, and when the dislocation block 521 rises and enters the sink 520, the T-shaped movable rod 517 moved to the position of the dislocation block 521 is released from the compressed state, so that the two clamping blocks 513 can release the clamping of the heat sink.

[0052] A welding machine bracket 524 is fixedly connected to the side of the surface of the adjustment sleeve 4 away from the positioning motor 507, and a transmission screw 525 is vertically rotatably connected inside the welding machine bracket 524.

An L-shaped slider 528 is fixedly connected to the side wall of the upper transmission screw sleeve 526, and one end of the L-shaped slider 528 is slidably connected to the surface of the vertical rod 522. It should be noted that: a welding motor is fixedly connected to the top of the welding machine bracket 524, and the rotating end of the welding motor is fixedly connected to the top of the transmission screw 525. The combination of the welding motor and the transmission screw 525 here is the existing technology and is not described in detail. When the transmission screw 525 rotates, the two transmission screw sleeves 526 move with the corresponding welding machine heads 527 to weld the two end positions of the heat sink. When the upper transmission screw sleeve 526 rises to the limit position, the L-shaped slider 528 on the surface of the upper transmission screw sleeve 526 slides and rises along the surface of the vertical rod 522. At this time, the L-shaped slider 528 can move up synchronously with the vertical rod 522 and the dislocation block 521 through the gasket 523, so that the dislocation block 521 enters the interior of the sink 520 and releases the pressure on the T-shaped movable rod 517. At this point, when the heat sink is welded, the two clamping blocks 513 are released from the clamping state.

[0053] In this embodiment, Figures 1 to 12 As shown, there are two hinge bars 512, which are symmetrically arranged inside the jacket 509, and a connecting rod is fixedly connected to the middle position of the two hinge bars 512, and the connecting rod is rotatably connected between the top and the bottom of the inner wall of the jacket 509. It should be noted that: a moving groove is provided on the inner wall of the jacket 509, and a moving block matching the moving groove is fixedly connected to the surface of the clamping block 513. In the process of the two clamping blocks 513 matching with the hinge bars 512, the two clamping blocks 513 can stably move relative to each other to clamp the heat sink, and the ends of the clamping blocks 513 and the side walls of the jacket 509 are both chamfered to avoid interference in the process of the clamping blocks 513 moving to the heat sink.

[0054] Hinge grooves are provided on both sides of the hinge bar 512, and a hinge pin is fixedly connected to the inner wall of the groove 514. The hinge bar 512 is hinged to the hinge pin through the hinge grooves.

[0056] In this embodiment, Figures 1 to 12As shown, a pressing spring is fixedly connected between the top of the dislocation block 521 and the inner top surface of the sink 520, and the side wall of the dislocation block 521 is set as an inclined surface that matches the side wall of the trapezoidal guide block 519. It should be noted that: when the L-shaped slider 528 moves down and resets, the pressing spring moves the dislocation block 521 down and resets and matches with the trapezoidal guide block 519 again.

[0057] In this embodiment, Figures 1 to 12 As shown, the middle part of the side wall of the storage box 3 is provided with a handle fixedly connected to the side wall of the push block 501, and the middle part of the handle is slidably connected to the inside of the horizontal groove. It should be noted that by pulling the handle to move the push block 501, it is convenient to add a batch of heat sinks to the inside of the storage box 3 at one time, ensuring that the number of heat sinks inside the storage box 3 is consistent with the number of welding ports on the surface of the transformer, so that after completing the welding of all heat sinks on a single transformer, the next batch of heat sinks can be added.

[0058] In this embodiment, Figures 1 to 12 As shown, the adjustment mechanism 7 includes an adjustment screw 701, which is rotatably connected to the top of the welding support 1, the inside of the adjustment screw sleeve 6 is threadedly connected to the surface of the adjustment screw 701, and adjustment gears 702 are arranged on both sides of the adjustment screw 701, and a one-way bearing 703 is fixedly connected between the inner ring of the adjustment gear 702 and the surface of the adjustment screw 701. It should be noted that: both ends of the adjustment screw 701 and the adjustment rod 2 are fixedly connected with pads, and the bottom of the pad is fixedly connected to the top surface of the welding support 1; the one-way bearing 703 is arranged, and when the adjustment rack 706 moves downward, it can mesh with the adjustment gear 702 to rotate with the adjustment screw 701, and vice versa, when the adjustment rack 706 is in the process of rising, it meshes with the adjustment gear 702, and at this time, the adjustment gear 702 cannot rotate with the adjustment screw 701.

[0059] The top of the welding support 1 is vertically slidably connected with a wedge plate 704 that cooperates with the positioning mechanism 5, and a compression spring 705 is fixedly connected between the bottom of the wedge plate 704 and the top of the welding support 1. Adjustment racks 706 are fixedly connected to both sides of the wedge plate 704. The two adjustment racks 706 are respectively meshed with two adjustment gears 702, and the lower part of the adjustment rack 706 is vertically slidably connected to the top of the welding support 1. It should be noted that: a vertical groove is provided on the top of the welding support 1, which cooperates with the adjusting rack 706, and a positioning rod is symmetrically fixedly connected to the bottom of the wedge block. A positioning hole is provided on the top of the welding support 1, which cooperates with the positioning rod. The compression spring 705 is movably sleeved on the surface of the positioning rod. The vertical groove and the positioning hole are set to ensure the stability of the wedge plate 704 and the adjusting rack 706 during the vertical sliding process on the top of the welding support 1; when the jacket 509 moves toward the wedge plate 704 with the pressure rod 515, the inclined surface of the side wall of the wedge plate 704 is compressed and moves the adjusting rack 706 downward, so that the adjusting rack 706 is meshed with the adjusting gear 702 and rotates with the adjusting screw 701. At this time, the adjusting screw 701 is meshed with the adjusting screw sleeve 6 to drive the storage box 3 to translate on the surface of the adjusting rod 2, so that the storage box 3 moves with the stored heat sink and switches to the next welding position.

[0060] In this embodiment, Figures 1 to 12 As shown, a method for using a welding device for transformer production includes the following steps:

[0061] S1. When in use, the transformer housing is clamped by the positioning telescopic cylinder 8 and the clamping plate 9. At the same time, the heat sink inside the storage box 3 moves to the position of the discharge slot 503 under the pressure of the push block 501 and the push spring 502. When the heat sink moves to the limit position at the discharge slot 503, under the action of the guide inclined plate 504, the heat sink at the rightmost position of the storage box 3 extends out from the inside of the discharge slot 503, and then the positioning motor 507 is started to rotate the positioning screw rod 505, so that the positioning screw sleeve 506 moves with the slide rod 508 and the clamping sleeve 509 toward the transformer housing;

[0062] S2. During the movement of the jacket 509, the positioning pin 511 on the jacket 509 cooperates with the positioning groove 510 on the inner wall of the adjusting sleeve 4 to slide, so that the jacket 509 enters the position of the discharge slot 503 and then presses the adjacent heat sink to move to the left. At this time, the heat sink on the left side of the storage box 3 is separated from the heat sink in the extended state. During this process, the middle part of the jacket 509 is in the same straight line as the middle part of the heat sink in the extended state, and the two clamping blocks 513 are respectively located on both sides of the heat sink in the extended state. As the jacket 509 continues to move, the T-shaped movable rod 517 on the jacket 509 cooperates with the side wall of the trapezoidal guide block 519 on the inner wall of the adjusting sleeve 4 to slide, so that the T-shaped movable rod 517 is pressed and moves with the adjacent clamping blocks 513 toward the middle direction of the jacket 509. At this time, with the cooperation of the hinge strip 512, the two clamping blocks 513 move relative to each other to clamp the heat sink in the extended state and move toward the welding port on the surface of the transformer housing;

[0063] S3, when the jacket 509 moves to the limit position with the clamped heat sink, the heat sink and the welding port of the transformer are plugged in, and the transmission screw 525 is started to rotate and move the two welding heads 527 to move back to each other, and the two ends of the heat sink are welded. When the transmission screw sleeve 526 and the welding head 527 on the upper part of the welding machine bracket 524 rise to the limit position, the upper transmission screw sleeve 526 and the L-shaped slider 528 press the gasket 523 on the vertical rod 522 to rise, and the gasket 523 and the vertical rod 522 and the dislocation block 521 rise inside the sink 520, so that the dislocation block 521 is offset from the trapezoidal guide block 519, and the T-shaped movable rod 517 is no longer pressed by the dislocation block 521, and resets and moves under the action of the reset spring 518, so that the two clamping blocks 513 inside the jacket 509 move back to each other and release the clamping of the welded heat sink;

[0064] S4, then start the positioning motor 507 to reverse the positioning screw rod 505, so that the jacket 509 and the clamp block 513 are reset and moved. When the jacket 509 is moved out of the discharge slot 503, the push block 501 inside the storage box 3 pushes the next heat sink to the discharge slot 503 again, and automatically replenishes the heat sink to the position to be welded;

[0065] S5. When the jacket 509 moves to the limit position with the pressure rod 515, the end of the pressure rod 515 presses against the inclined surface of the side wall of the wedge plate 704, so that the wedge plate 704 is pressed and moves the adjusting rack 706 downward. At this time, the adjusting rack 706 is engaged with the adjusting gear 702 on the surface of the adjusting screw rod 701, and the adjusting gear 702 and the one-way bearing 703 cooperate to drive the adjusting screw rod 701 to rotate. At this time, the adjusting screw sleeve 6 drives the storage box 3 to translate on the surface of the adjusting screw rod 701, and automatically moves the heat sink to be welded on the storage box 3 to the next welding port position.

A method for using a welding device for transformer production, characterized in that: Using a welding device for transformer production as described in any one of claims 1 to 7 comprises the following steps: S1. When in use, the transformer housing is clamped by the positioning telescopic cylinder (8) and the clamping plate (9), and the heat sink inside the storage box (3) moves to the position of the discharge slot (503) under the pressure of the push block (501) and the push spring (502). When the heat sink moves to the limit position at the discharge slot (503), the heat sink at the rightmost position of the storage box (3) extends from the inside of the discharge slot (503) under the action of the guide inclined plate (504), and then the positioning motor (507) is started to rotate with the positioning screw rod (505), so that the positioning screw sleeve (506) moves with the slide rod (508) and the clamping sleeve (509) toward the transformer housing; S2. During the movement of the jacket (509), the positioning pin (511) on the jacket (509) slides in cooperation with the positioning groove (510) on the inner wall of the adjusting sleeve (4), so that the jacket (509) enters the position of the discharge slot (503) and presses against the adjacent heat sink to move to the left. At this time, the heat sink on the left side of the storage box (3) is separated from the heat sink in the extended state. During this process, the middle part of the jacket (509) is in the same straight line as the middle part of the heat sink in the extended state, and the two clamping blocks (513) are respectively in the extended state. The positions of the heat sink in the extended state are adjusted, and as the jacket (509) continues to move, the T-shaped movable rod (517) on the jacket (509) and the side wall of the trapezoidal guide block (519) on the inner wall of the adjustment sleeve (4) slide in cooperation, so that the T-shaped movable rod (517) is pressed and moves the adjacent clamping blocks (513) toward the middle of the jacket (509).

When the clamped heat sink is moved to the limit position with the jacket (509), the heat sink is plugged into the welding port of the transformer. At this time, the transmission screw (525) is started to rotate and move the two welding heads (527) back to back to perform welding operations on the two ends of the heat sink. When the transmission screw sleeve (526) and the welding head (527) on the upper part of the welding machine bracket (524) rise to the limit position, the upper transmission screw sleeve (526) with the L-shaped slider (528) presses against the vertical rod ( The gasket (523) on the vertical rod (522) rises, and the gasket (523) brings the vertical rod (522) and the misalignment block (521) to rise inside the sink (520), so that the misalignment block (521) and the trapezoidal guide block (519) are offset. At this time, the T-shaped movable rod (517) is no longer pressed by the misalignment block (521), and is reset and moved under the action of the reset spring (518), so that the two clamping blocks (513) inside the clamping sleeve (509) move back to each other and release the clamping of the welded heat sink; S4, then start the positioning motor (507) to reverse the positioning screw rod (505), so that the jacket (509) and the clamp block (513) are reset and moved.
