Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a quick welding device used for after-sales maintenance of medical equipment. Background Art

[0002] Welding plays a key role in the after-sales maintenance of medical devices, especially for the maintenance needs of tubular medical devices. Due to frequent use in complex environments, these devices are easily affected by external forces, resulting in wear and damage, and often require welding repair. Through welding, these problems can be effectively solved to ensure that the repaired devices restore good performance and safety.

[0003] The patent with publication number CN211727821U discloses a welding tool for repairing medical equipment, including a base plate, a fixing seat and a pressure plate. A fixing block is fixedly connected to one side of the upper surface of the base plate, a sliding rod is fixedly connected to the inner side of the fixing block, a base is slidably connected to the surface of the sliding rod, and a sliding groove is provided on the upper surface of the base. The welding tool for repairing medical equipment can press the lower surface of the pressure plate against the medical equipment by adjusting the adjustment handle on the threaded rod. The pressure plate and the fixing seat form a splint to fix the medical equipment. The friction between the fixing seat and the upper surface of the base is increased by setting a rubber pad to avoid relative displacement of the medical equipment caused by shaking during the welding process.

[0004] During the welding repair process, the welding quality requirements are extremely strict to ensure that the repaired medical device can fully restore its original performance and accuracy. To achieve this goal, spot welding technology with higher precision and controllability is usually used. However, when using spot welding, workers are usually required to hold the welding gun and move it back and forth at the position where the medical device needs to be repaired. This method significantly increases the labor intensity of the workers. In addition, during the welding repair process of tubular medical devices, in order to ensure the uniformity and integrity of the welding, the medical device is often required to be rotated so that the worker can weld in the most suitable position. This operation not only increases the difficulty of the worker's operation, but also prolongs the welding time of the medical device.

[0005] In view of this, we propose a rapid welding device for after-sales maintenance of medical devices. Summary of the invention

[0058] Furthermore, after the lifting cylinder 210 is started, the fixed horizontal plate 220 and the four lifting rods 230 are driven to move upward, thereby driving the lifting plate 240 and the two sets of clamping devices 600 located below to move upward together, causing the clamping device 600 located below to collide with the clamping device 600 located above.

[0059] In this embodiment, Figure 6-Figure 7 As shown, the driving device 300 includes a driving motor 310, a dial 320 that rotates as the output shaft of the driving motor 310 rotates, a moving bracket 330 that moves up and down as the dial 320 rotates, an outrigger 340 disposed at the left and right ends of the crossbar of the moving bracket 330, a moving tooth plate 350 disposed at the end of the outrigger 340, and a docking bracket 360 that is symmetrically disposed with the moving bracket 330;

[0062] Furthermore, after the driving motor 310 is started, the dial 320 and the lever 321 are driven to rotate. When the lever 321 rotates in the frame slide groove 331 of the movable bracket 330, the movable bracket 330 and the docking bracket 360 are driven to move up and down, thereby driving the welding gun 400 to move up and down above the position where the tubular medical device needs to be repaired. When the movable bracket 330 moves up and down, the outrigger rods 340 at both ends are driven to move up and down together, thereby driving the movable tooth plate 350 to move up and down.

[0063] In this embodiment, Figure 8-Figure 11 As shown, the transmission device 500 includes a rotating shaft 510, a shaft gear 520 sleeved on the outer side of the rotating shaft 510, a toggle portion 530 that rotates as the shaft gear 520 rotates, a rotating rod 540 disposed on the outer side of the toggle portion 530, a rotating disk 550 and a rod gear 560 sleeved on the outer side wall of the rotating rod 540, an intermediate gear 570 that rotates as the rod gear 560 rotates, and a transmission portion 580 disposed between the rotating shaft 510 and the toggle portion 530, and a plurality of regularly distributed disk grooves 551 are opened on the outer side wall of the rotating disk 550;

[0064] Specifically, the toggle portion 530 includes a disc 531, a disc body cam shaft 532 integrally formed at the center position of the disc 531, two groups of outer protrusions 533 symmetrically arranged on the outer wall of the disc 531, an inner plug-in block 534 slidably connected to the inside of the outer protrusion 533, and a second pressure spring 535 welded and fixed to the outer wall of the inner plug-in block 534. The disc body cam shaft 532 is rotatably connected to the inner wall of the top horizontal plate of the fixed frame plate 120. The end of the inner plug-in block 534 is arc-shaped and its size is adapted to the size of the disc body groove 551. The end of the second pressure spring 535 is welded and fixed to the inner wall of the outer protrusion 533.

[0065] Furthermore, the transmission part 580 includes two sets of pulleys 581 arranged in parallel and a synchronous belt 582 sleeved between the two sets of pulleys 581. The pulley 581 at the front end is fixedly connected to the outer wall of the rotating shaft 510 by a pin, and the pulley 581 at the rear end is fixedly connected to the outer wall of the disc body convex shaft 532 by a pin.

[0066] Furthermore, both ends of the rotating shaft 510 are rotatably connected to the groove walls of the circular groove 121 , and the shaft gear 520 is fixedly connected to the outer side of the rotating shaft 510 through a bayonet pin and meshes with the movable gear plate 350 .

[0067] Furthermore, the end of the rotating rod 540 is rotatably connected to the outer groove wall of the circular groove 121, the rotating disk 550 and the rod body gear 560 are fixedly connected to the outer wall of the rotating rod 540 by a pin, and the intermediate gear 570 is rotatably connected to the interior of the lower convex warehouse body 130 through the center rod, and the intermediate gear 570 is meshed with the rod body gear 560.

[0068] Furthermore, at this time, as the movable tooth plate 350 moves up and down, the shaft gear 520 in the transmission device 500 is driven to reciprocate together with the rotating shaft 510, and the pulley 581 fixed on the outside of the rotating shaft 510 is driven to reciprocate. After the power is transmitted through the synchronous belt 582, the pulley 581 fixed on the outside of the disc body convex shaft 532 in the toggle part 530 is driven to reciprocate, so that the disc body convex shaft 532 reciprocates with it; during the reciprocating rotation of the disc body convex shaft 532, the disc 531 is driven to reciprocate as a whole, and the disc 531 When rotating counterclockwise, the arc surface of the inserted block 534 conflicts with the arc groove surface in the upper disk body groove 551 of the rotating disk 550, and shrinks into the interior of the outer protrusion 533, and under the elastic force of the second pressure spring 535, extends to the interior of another disk body groove 551; then, when the disk 531 rotates clockwise, the inserted block 534 conflicts with the straight groove surface in the upper disk body groove 551 of the rotating disk 550, and drives the rotating disk 550 together with the rotating rod 540 and the rod body gear 560 to rotate clockwise, thereby driving the intermediate gear 570 to rotate.

[0069] In this embodiment, Figure 12-14 As shown, the clamping device 600 includes a mounting block 610, a rotating ring 620 rotatably connected to the inside of the mounting block 610, two magnetic sliders 630 arranged on the outer wall of the rotating ring 620, an annular wall gear 640 arranged between the two magnetic sliders 630, and a rubber pad 650 adhered to the inner annular wall of the rotating ring 620.

[0070] Specifically, the upper mounting block 610 is snap-fitted and fixed to the bottom of the lower convex bin body 130, and the lower mounting block 610 is snap-fitted and fixed to the end of the lifting rod 230. A block through groove 611 that passes through the upper and lower parts is opened at the center position of the mounting block 610, and limiting grooves 612 with T-shaped cross-sections are opened on both sides of the block through groove 611 inside the mounting block 610, and a circular hole connected to the limiting groove 612 is opened on the top surface of the mounting block 610.

[0071] Furthermore, the magnetic slide 630 and the annular wall gear 640 are both clamped and fixed on the outer ring wall of the rotating ring 620, the magnetic slide 630 is slidably connected to the inside of the limiting slide groove 612, the annular wall gear 640 is meshed with the intermediate gear 570, and the limiting protrusion 660 is slidably connected to the inside of the opening at the center of the top surface of the magnetic slide 630, and the bottom end of the limiting protrusion 660 is welded and fixed with a third pressure spring 670, and the bottom end of the third pressure spring 670 is welded and fixed to the hole wall of the opening on the top surface of the magnetic slide 630.

[0072] Furthermore, the block through groove 611 in the mounting block 610 is used to provide a rotation range for the intermediate gear 570 and the annular wall gear 640, and the limiting slide groove 612 is used to provide a rotation range for the magnetic slider 630. After the mounting block 610 located at the bottom collides with the mounting block 610 located at the top, at this time, the magnetic slider 630 in the upper and lower clamping devices 600 connects the two sets of rotating rings 620 into a whole under the action of magnetic force. When the two semicircular rubber pads 650 are in close contact with the tubular medical device and are squeezed, they will generate elastic force due to their own deformation, and this elastic force is immediately converted into a force applied firmly and evenly on the outer wall of the tubular medical device. The toothed design further The stability and gripping force of this force are further enhanced. After the intermediate gear 570 rotates, it conflicts with the annular wall gear 640 located in the upper clamping device 600, and drives the upper and lower rotating rings 620 to rotate as a whole, so that the tubular medical device fixed inside the two rubber pads 650 rotates, thereby cooperating with the welding gun 400 moving up and down to complete the maintenance welding of the tubular medical device. The elastic force provided by the third pressure spring 670 pushes the limiting protrusion 660 to move outward. When the limiting protrusion 660 extends to above the circular hole on the top surface of the mounting block 610, it ensures that in the absence of external force, the position of the magnetic slider 630 in the limiting slide groove 612 can be kept fixed.

[0073] Finally, it should be noted that the lifting cylinder and driving motor involved in the present invention are universal standard parts or parts known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, the lifting cylinder and driving motor are connected to the external power supply through wires. The specific connection method should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection methods are all well-known technologies in this field.

[0074] When the quick welding device for after-sales maintenance of medical devices of the present invention is used, first, the welding worker places two groups of tubular medical devices to be welded on the top surface of the fixed box 110 respectively, and ensures that the positions of the two groups of tubular medical devices are respectively placed in the middle of the two lifting plates 240 in the lifting device 200;

[0075] Subsequently, the lifting cylinder 210 in the lifting device 200 is started, and the fixed horizontal plate 220 and the four lifting rods 230 are driven to move upward, thereby driving the lifting plate 240 and the two groups of clamping devices 600 located below to move upward together, until the mounting block 610 in the clamping device 600 located below conflicts with the mounting block 610 in the clamping device 600 located above. At this time, the magnetic sliders 630 in the upper and lower groups of clamping devices 600 connect the two groups of rotating rings 620 into a whole under the action of magnetic force;

[0076] During the upward movement of the lifting plate 240, the welding worker fine-tunes the positions of the two groups of tubular medical devices that need to be welded, ensuring that the positions that need welding and repair are placed directly below the welding gun 400;

[0077] Next, the driving motor 310 in the driving device 300 is started to drive the dial 320 and the lever 321 to rotate. When the lever 321 rotates in the frame slide slot 331 of the movable bracket 330, the movable bracket 330 and the docking bracket 360 are driven to move up and down, thereby driving the welding gun 400 to move up and down above the position where the tubular medical device needs to be repaired;

[0078] When the movable bracket 330 moves up and down, the outriggers 340 at both ends are driven to move up and down together, thereby driving the movable toothed plate 350 to move up and down;

[0079] At this time, as the movable toothed plate 350 moves up and down, the shaft gear 520 in the transmission device 500 is driven to move back and forth together with the rotating shaft 510, and the pulley 581 fixed on the outer side of the rotating shaft 510 is driven to reciprocate, and after the power is transmitted through the synchronous belt 582, the pulley 581 fixed on the outer side of the disc body convex shaft 532 in the toggle part 530 is driven to reciprocate, so that the disc body convex shaft 532 reciprocates with it;

[0080] During the reciprocating rotation of the disc body convex shaft 532, the disc 531 is driven to reciprocate as a whole. When the disc 531 rotates counterclockwise, the arc surface of the inner insert block 534 contacts the arc groove surface in the disc body groove 551 on the rotating disc 550, and shrinks into the inside of the outer convex block 533, and extends to the inside of another disc body groove 551 under the elastic force of the second pressure spring 535;

[0081] Next, when the disc 531 rotates clockwise, the insert block 534 contacts the linear groove surface in the groove 551 of the rotating disc 550, driving the rotating disc 550, the rotating rod 540 and the rod gear 560 to rotate clockwise, thereby driving the intermediate gear 570 to rotate;

[0082] After the intermediate gear 570 rotates, it conflicts with the annular wall gear 640 in the upper clamping device 600, and drives the upper and lower rotating rings 620 to rotate as a whole, so that the tubular medical device fixed inside the two rubber pads 650 rotates, thereby cooperating with the welding gun 400 moving up and down to complete the maintenance welding of the tubular medical device;

[0083] Subsequently, after the welding is completed, the telescopic rod in the lifting cylinder 210 is controlled to move downward, and the repaired tubular medical device can be taken out.
