Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a generator welding machine tool which can automatically adapt to different specifications. Background Art

[0002] When the motor runs at high speed for a long time, a large amount of heat will be generated inside it. The heat will be dissipated to the outside through the motor casing. In order to improve the heat dissipation efficiency of the motor casing, multiple cooling fins need to be arranged on the motor casing to increase the contact area between the motor casing and the air.

[0003] The heat sink is generally welded to the surface of the casing. In order to ensure the welding effect of the heat sink, a welding tool is generally used, such as a motor casing welding tool with application number: CN202223026231.9. The tool fixes the motor casing through a fixed cylinder, and then uses a heat sink fixing mechanism to position multiple heat sink fins at equal intervals in an arc shape on the outside of the motor casing. The positioning is more precise, so that equal spacing is maintained between multiple heat sinks, and it is convenient for welding operations. There is no need to fix the heat sink to the outside of the motor casing by spot welding in advance, which simplifies the welding operation and improves the welding efficiency.

[0004] However, in the actual application process, the tooling has some shortcomings: first, the tooling does not have the function of automatic loading, which requires the staff to manually place each heat sink one by one on the corresponding fixed structure. This process is not only time-consuming and labor-intensive, but also greatly reduces work efficiency; secondly, the tooling lacks flexibility in design and cannot flexibly adjust the distance between the two heat sinks according to different needs, which to a certain extent limits its scope of application and efficiency.

[0068] In this embodiment, the working principle of the feeding mechanism 5 is that when the first feeding part 51 pushes the heat sink to be welded to move forward, the gas feeding part 53 is responsible for providing power to the second feeding part 54, so that the second feeding part 54 pushes the heat sink to move into the feeding cavity 32; the feeding part 52 transports the heat sink to the welding position of the welding mechanism 6 through mechanical transmission.

[0069] Next, please refer to Figure 1 and Figures 4 to 6The auxiliary clamping mechanism 2 includes a turntable 201, which is rotatably connected to the upper end of the housing 1. The top surface of the turntable 201 is provided with a guide groove 202 in an annular distribution. A guide block 203 is slidably connected in the guide groove 202. A fixed plate 204 is fixedly connected to the guide block 203. An electric push rod 205 is installed at one end of the guide groove 202, and the telescopic end of the electric push rod 205 is fixedly connected to the guide block 203. A rotating seat 206 is fixedly connected to the bottom surface of the inner cavity of the housing 1. The outer ring of the rotating seat 206 is provided with protrusions 2 in an array distribution. 07. A rotating motor 208 is also installed on the bottom surface of the inner cavity of the shell 1. A small gear 209 is installed on the upper end of the output shaft of the rotating motor 208. A large gear 210 is installed on the lower end of the rotating seat 206. The top surface of the rotating seat 206 is provided with arc grooves 211 in a ring-shaped distribution. A movable block 212 is slidably connected in the arc groove 211, and the upper end of the movable block 212 is fixedly connected to the bottom surface of the turntable 201. A first compression spring 213 is fixedly connected to the movable block 212, and the other end of the first compression spring 213 is fixedly connected to the inner wall of the arc groove 211.

[0070] In this embodiment, the casing to be processed is sleeved outside the three fixing plates 204, and then the three electric push rods 205 are controlled to be shortened synchronously, so that the three fixing plates 204 are separated from each other and contact the inner wall of the casing to achieve fixation.

[0071] Secondly, please refer to Figure 7 The sliding base 4 includes a sliding sleeve 401, which is fixedly connected to the outer shell 1. A first sliding seat 402 is slidably connected in the sliding sleeve 401, a second sliding seat 403 is slidably connected in the first sliding seat 402, and the second sliding seat 403 is fixedly connected to the feed box 3. A spring 404 is fixedly connected between the sliding sleeve 401 and the first sliding seat 402. A threaded rod 405 is threadedly connected to the first sliding seat 402, and the other end of the threaded rod 405 is rotatably connected to the second sliding seat 403; wherein, the right side of the first sliding seat 402 is connected to a limiting block 8, the left side of the turntable 201 is connected to a limiting seat 9, and a contact switch 10 is arranged in the limiting seat 9.

[0072] In this embodiment, before welding, the threaded rod 405 is rotated to cause the second sliding seat 403 to move along the first sliding seat 402 to adjust the position of the welding mechanism 6 and make the heat sink at the rightmost end of the feed cavity 32 contact the outer surface of the casing to ensure that it can weld the fixed heat sink.

[0073] Please refer again Fig. 9 and Fig.10The welding mechanism 6 includes a support plate 601, and the two support plates 601 are fixedly connected to the feed box 3 by a support rod. A rotating rod 602 is rotatably connected between the two support plates 601. A wire block 603 is sleeved on the rotating rod 602. A sliding rod 604 is slidably connected to the wire block 603, and the two ends of the sliding rod 604 are respectively fixedly connected to the two support plates 601. A driving motor 605 is installed on the support plate 601, and the output shaft of the driving motor 605 is fixed to the central rotating shaft of the rotating rod 602. A welding gun 606 is installed on the wire block 603, a U-shaped air pipe 607 is fixedly connected to the welding gun 606, and the U-shaped air pipe 607 is divided into an air inlet pipe and an air outlet pipe, a negative pressure fan 608 and an activated carbon adsorption layer 609 are installed in the air inlet pipe, a driving gear 612 is fixedly installed at the lower end of the rotating rod 602, a refrigeration box 610 is arranged on the top surface of the U-shaped air pipe 607, a heat dissipation column 611 is fixedly connected to the upper end of the air outlet pipe, and the upper end of the heat dissipation column 611 extends into the refrigeration box 610.

[0074] In this embodiment, during the welding process, the drive motor 605 is started to drive the rotating rod 602 to rotate, and the rotation of the rotating rod 602 causes the wire block 603 to move (the outer wall of the rotating rod 602 is provided with a thread compatible with the wire block 603, and the rotating rod 602 is threadedly connected to the wire block 603), and the movement of the wire block 603 drives the welding gun 606 to move downward, thereby realizing a top-down welding operation; at the same time, the negative pressure fan 608 is started to suck the generated harmful gas into the air inlet pipe on the U-shaped air pipe 607, and the harmful gas is adsorbed and purified by the activated carbon adsorption layer 609, thereby effectively controlling the emission of welding smoke and improving the working environment; the purified air enters the air outlet pipe through the air inlet pipe, and the gas contacts the heat dissipation column 611 when flowing along the air outlet pipe, and the gas is cooled by heat exchange, and finally discharged from the air outlet pipe to blow toward the welding point to achieve the purpose of cooling.

[0075] It should be added that the refrigeration box 610 is filled with coolant, and the function of the refrigeration box 610 is to cool the coolant inside. The welding gun 606, the negative pressure fan 608 and the refrigeration box 610 are all products currently available on the market. When selecting the model, you should try to choose one that meets the requirements of this application under the premise of suitable specifications and usage scenarios. The specific model specifications are not limited here.

[0076] It should be noted that the threads on the two rotating rods 602 have opposite rotation directions, and the two driving motors 605 have opposite rotation directions when rotating.

[0077] Next, please refer to Fig.11 The first material pushing part 51 includes a guide rod 511, which is slidably inserted into the rear end of the feeding box 3, and a second compression spring 512 is sleeved on the guide rod 511. One end of the guide rod 511 is fixedly connected to a first push plate 513.

[0078] In this embodiment, the first push plate 513 is first pushed backward and the second compression spring 512 is compressed, and then the heat sink to be welded is placed in the storage cavity 31, and the heat sink is arranged in an array in the delivery cavity 32.

[0079] Next, the first push plate 513 is released, and the elastic force of the second compression spring 512 pushes the first push plate 513 forward, thereby sending the heat sink to the designated position in sequence. In this way, a continuous and automated welding process of the heat sink can be achieved, greatly improving production efficiency and welding quality.

[0080] In addition, the design of the guide rod 511 ensures the linear movement of the first push plate 513, avoiding the problem of inaccurate delivery due to deviation.

[0081] Please refer again Figures 11 to 13 The feeding part 52 includes round rods 521, which are rotatably connected to the feeding box 3 in an array distribution. A feeding roller 522 is installed on the round rods 521. The lower end of the round rods 521 is fixedly connected to the first transmission gear 523. The lower end of the rightmost round rod 521 is also rotatably connected to the second transmission gear 524. The lower end of the round rod 521 is located in the second transmission gear 524 and a ratchet 525 is fixedly installed. The inner wall of the second transmission gear 524 is rotatably connected to a pawl 526, and a third compression spring 527 is fixedly connected to the pawl 526, and the other end of the third compression spring 527 is fixedly connected to the inner wall of the second transmission gear 524.

[0082] In this embodiment, when the rotating rod 602 starts to rotate and moves the wire block 603 downward, the rotating action of the rotating rod 602 will drive the driving gear 612 to rotate accordingly. The rotating action of the driving gear 612 is transmitted by the toothed belt, and further drives the second transmission gear 524 to start rotating. Inside the second transmission gear 524, a ratchet 526 is provided, and the ratchet 526 and the ratchet 525 are meshed with each other. Therefore, when the second transmission gear 524 rotates, the ratchet 526 will push the ratchet 525 to rotate together. As the ratchet 525 rotates, it will drive the round rod 521 on the right side to start rotating. The first transmission gear 523 on the multiple round rods 521 ensures that the multiple round rods 521 on the same side can rotate synchronously through the transmission effect of the toothed belt. The rotating action of the round rod 521 will further drive the feed roller 522 to start rotating. The rotating action of the feed roller 522 is to effectively transport the heat sink to be welded by using the front and rear sides and the opposite rotation direction. When the rotating rod 602 rotates in the opposite direction, driving the wire block 603 to move upward and reset, the pawl 526 in the second transmission gear 524 will not mesh with the ratchet 525. In this case, even if the second transmission gear 524 continues to rotate, the ratchet 525 will not rotate because the pawl 526 is not meshed with the ratchet 525, thereby not affecting the movement of the round rod 521 and the feeding roller 522.

[0083] Please refer again Fig.15 and Fig.16 The gas delivery part 53 includes a disc 531, which is fixedly connected to the leftmost round rod 521, and a first lever 532 is fixedly connected to the lower end of the disc 531. A connecting rod 533 is rotatably connected to the bottom surface of the feed box 3. A guide rail 534 is also fixedly connected to the bottom surface of the feed box 3. A slider 535 is slidably connected to the guide rail 534. A second lever 536 is fixedly connected to the bottom surface of the slider 535. A first hollow cylinder 537 is fixedly connected to the bottom surface of the feed box 3. A movable rod 538 is inserted at one end of the first hollow cylinder 537. A piston plate 539 is fixedly connected to one end of the movable rod 538, and the other end of the movable rod 538 is fixedly connected to the slider 535.

[0084] Please refer again Fig.14 and Fig.15 The second pushing part 54 includes a second hollow cylinder 541, the second hollow cylinder 541 is fixedly connected to the left end of the feed box 3, one end of the second hollow cylinder 541 is slidably inserted with the third hollow cylinder 542, one end of the third hollow cylinder 542 is slidably inserted with a push rod 543, a tension spring 544 is connected between the second hollow cylinder 541 and the third hollow cylinder 542, a fourth compression spring 545 is fixedly connected between the push rod 543 and the third hollow cylinder 542, the other end of the push rod 543 is fixedly connected with a second push plate 546, one end of the second hollow cylinder 541 is connected with an air pipe 547, and the other end of the air pipe 547 is connected to the first hollow cylinder 537.

[0085] In this embodiment, the left circular rod 521 drives the disc 531 to rotate when rotating, and the rotation of the disc 531 drives the connecting rod 533 to rotate through the first lever 532, and then the slider 535 is moved through the cooperation of the connecting rod 533 and the second lever 536. When the slider 535 drives the movable rod 538 to move into the first hollow cylinder 537, it drives the piston plate 539 to move and compress the air in the first hollow cylinder 537, and vice versa, the air is exhausted; the compressed air in the first hollow cylinder 537 The gas is transmitted to the second hollow cylinder 541 through the gas delivery pipe 547, and then the third hollow cylinder 542 is pushed to slide along the second hollow cylinder 541 by the gas pressure, and the tension spring 544 is stretched. The sliding of the second hollow cylinder 541 drives the push rod 543 and the second push plate 546 to move, and the heat sink in the material storage chamber 31 is pushed into the material delivery chamber 32 by the movement of the second push plate 546, so as to transport the material. On the contrary, when the gas is pumped out, the third hollow cylinder 542 is sucked into the second hollow cylinder 541 to reset it.

[0086] During the welding process, when the heat sink in the feeding cavity 32 is full, the second push plate 546 is blocked by the heat sink and cannot move forward. At this time, when the third hollow cylinder 542 moves, the ejector rod 543 will shrink into the third hollow cylinder 542 and squeeze the fourth compression spring 545, thereby ensuring the stable delivery of the heat sink. Through the coordinated use of multiple components, the purpose of automatic feeding is achieved, reducing the labor burden of the staff in feeding.

[0087] Supplementary explanation: An air hole is opened at the right end of the first hollow cylinder 537. When the piston plate 539 moves to the right end, air can enter the first hollow cylinder 537 along the air hole to replenish the gas lost during operation and ensure the stability of the air pressure.

[0088] Please refer again Fig.17 The force-bearing mechanism 7 includes a sleeve plate 701, which is fixedly connected to the bottom surface of the first sliding seat 402. A plug plate 702 is plugged into the lower end of the sleeve plate 701, and the plug plate 702 is provided with lock holes distributed in an array. A fastening bolt 703 is provided on the sleeve plate 701, and a force-bearing rod 704 is fixedly connected to the lower end of the plug plate 702. A vertical rod is fixedly connected to the plug plate 702, and a sleeve block is slidably connected to the vertical rod, and the sleeve block is fixedly connected to the sleeve plate 701, which can increase the connection strength between the sleeve plate 701 and the plug plate 702.

[0089] In this embodiment, after a heat sink is welded, the rotating motor 208 needs to be started, and the start of the motor will drive the small gear 209 to start rotating. The small gear 209 is tightly meshed with the large gear 210, and this meshing relationship will cause the rotating seat 206 to start rotating. During the rotation of the rotating seat 206, the rotating disk 201 will not be able to rotate because the limit block 8 is stuck in the limit seat 9. As the rotating seat 206 continues to rotate, it will apply pressure to the first compression spring 213, producing a squeezing effect.

[0090] The protrusion 207 on the outside of the rotating seat 206 will push the force-bearing mechanism 7 to move to the left, and the leftward movement of the force-bearing mechanism 7 will drive the second sliding seat 403 to move to the left as well, and squeeze the spring 404. As the second sliding seat 403 moves to the left, the feed box 3 will also be driven to move to the left, so that the welded heat sink can be separated from the feed cavity 32. At the same time, the limit block 8 will also be separated from the limit seat 9, and the rotating disk 201 will lose its limit at this time, so it can be rotated. Under the reset force of the first compression spring 213, the movable block 212 will move, and the movement of the movable block 212 will drive the rotating disk 201 to move, thereby compensating for the rotation angle. When the protrusion 207 no longer applies pressure to the force-bearing mechanism 7, the reset force of the spring 404 will reset the second sliding seat 403 and the feed box 3. Subsequently, the limit block 8 will be reinserted into the limit seat 9 and squeeze the contact switch 10, which will trigger a signal to turn off the rotating motor 208, thereby completing the adjustment of the housing angle. Through this process, the heat sink can be welded to the outer surface of the casing in an all-round manner.

[0091] It is worth noting that the protrusions 207 are arranged in a vertical array, and only three rows are shown in the figure. The length of the protrusions 207 in each row is gradually increased. This design prolongs the time for the limit block 8 to leave the limit seat 9, and the rotation angle increases accordingly, so that the distance between the two heat sinks can be adjusted.

[0092] The plug plate 702 is slidably inserted in the sleeve plate 701. When the height of the force-bearing rod 704 needs to be adjusted to match the protrusions 207 of different heights, the fastening bolt 703 can be removed. After removal, the plug plate 702 can be moved freely, and the height of the force-bearing rod 704 can be adjusted by moving the plug plate 702. After the adjustment is completed, the fastening bolt 703 only needs to be screwed into the corresponding lock hole on the plug plate 702 to fix the position of the plug plate 702 and ensure that the height of the force-bearing rod 704 is adjusted to the right position.

[0093] The working principle of the present invention is:

[0094] The housing to be processed is clamped and rotated by means of components such as the electric push rod 205, the turntable 201, the guide groove 202, the guide block 203 and the fixing plate 204.

[0095] The rotary motor 208 drives the small gear 209 to mesh with the large gear 210, driving the entire clamping structure to rotate as required to complete multi-angle welding.

[0096] The first material pushing part 51 and the second material pushing part 54 work together to push the heat sink to be welded from the material storage chamber 31 to the material delivery chamber 32 by compressing the elastic force provided by the second compression spring 512 and the pressure generated by the pneumatic system (including the disc 531, the first lever 532, etc.).

[0097] The feeding portion 52 utilizes a series of transmission gears (such as the first transmission gear 523 , the ratchet 525 , etc.) and a feeding roller 522 to achieve orderly transportation of the heat sink in the feeding cavity 32 .

[0098] The sliding base 4 adopts a double-layer sliding structure (a first sliding base 402 and a second sliding base 403), combined with a spring 404 and a threaded rod 405, so as to adjust the position of the feed box 3 so as to accurately place or remove the heat sink.

[0099] The force-bearing mechanism 7 adjusts the height of the force-bearing rod 704 through the design of the sleeve plate 701 , the plug plate 702 and the lock hole therein to adapt to different heights of the protrusions 207 , thereby controlling the rotation range of the turntable 201 .

[0100] The welding mechanism 6 is composed of a support plate 601 , a rotating rod 602 , a wire block 603 , a welding gun 606 , etc., wherein a driving motor 605 drives the rotating rod 602 to rotate, thereby moving the wire block 603 along the sliding rod 604 , thereby achieving precise control of the position of the welding gun 606 .

[0101] A negative pressure fan 608 and an activated carbon adsorption layer 609 are provided in the U-shaped air pipe 607 to purify harmful gases generated during the welding process.

[0102] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
