Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an energy-saving and high-efficiency pneumatic spot welding machine. Background Technology

[0002] A pneumatic spot welding machine uses the pressure generated by compressed air to press the workpiece together, and applies current through electrodes to generate resistance heat at the contact points, thereby achieving welding. In industrial production, pneumatic spot welding machines are widely used in automobile manufacturing, electronic equipment production, and home appliance manufacturing.

[0003] Chinese patent application CN217913576U discloses an energy-saving and high-efficiency pneumatic spot welding machine. This patent application solves the problem that in the clamping process of stainless steel kettles, the rounded surface of the kettle makes it inconvenient to clamp stably, causing displacement during welding, reducing the processing speed of the pneumatic spot welding machine, and wasting electricity. At the same time, existing pneumatic spot welding machines are inconvenient to quickly install the processing table. However, the above patent still has the following shortcomings:

[0004] (1) When welding stainless steel kettles with traditional pneumatic spot welding machines, the welding slag is easy to stick and difficult to clean. Uneven cooling causes workpiece deformation. The combination of manual cleaning and high-pressure blowing is energy-intensive and inefficient, which restricts production.

[0005] (2) After welding, stainless steel kettles cool down slowly by nature and cool down unevenly by ordinary air blowing.

[0006] (3) When welding stainless steel kettles, the friction of the electrodes and the ionization of the air can easily generate static electricity, which adsorbs dust and welding slag, affecting the surface finish.

[0018] Beneficial effects

[0019] This invention provides an energy-efficient and high-performance pneumatic spot welding machine. Compared with the prior art, it has the following advantages:

[0020] (1) By setting up the swing cooling and slag-adhesion mechanism, the empty roller is in contact with the stainless steel kettle shell and rolls, so that the air outlet rotates continuously and the blown air changes angle continuously, and blows evenly to one side of the stainless steel kettle shell for cooling. At the same time, when the empty roller is in contact with the stainless steel kettle shell, some welding slag that is not easy to blow away can be adhered, preventing the welding slag from affecting the surface smoothness of the stainless steel kettle shell after it cools down. There is no need to use a high-pressure blowing device, so the energy consumption is low and the efficiency is high.

[0021] (2) By setting up a lifting and stopping water spraying component, water is sprayed at two positions, high and low, using the nozzle. It is used in conjunction with the swing cooling and slag-adhesion mechanism. The air blown out of the air outlet blows the water mist onto the stainless steel kettle shell. When spraying water mist at a high position, the low-density water mist covers the medium temperature zone, slowly cooling down to balance the overall temperature and avoid local sudden cooling that causes cracks, thus achieving initial cooling. Then, water mist is sprayed from a low position, so that the high-density water mist directly acts on the high-temperature zone. The water vaporization absorbs heat to quickly reduce the temperature of the weld point and prevent overheating damage. Compared with natural cooling and ordinary blowing cooling, this water mist combined with blowing can achieve cooling more quickly and evenly, and can also avoid local sudden cooling after the stainless steel kettle shell is welded, thus improving the yield rate.

[0022] (3) By setting up the electrostatic discharge component, the static electricity generated by electrode friction and air ionization during the welding of stainless steel kettle shell is intermittently discharged, thereby effectively preventing the stainless steel kettle shell from adsorbing dust and welding slag, and further improving the surface finish.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The present invention provides three technical solutions, specifically including the following embodiments:

[0034] Example 1

[0035] Please see Figures 1-4 An energy-saving and high-efficiency pneumatic spot welding machine includes a welding base 1, a welding station 2 fixed on one side of the welding base 1, the welding station 2 providing welding support for spot welding, and a swing cooling and slag-adhesive mechanism 3 provided on one side of the welding base 1. The swing cooling and slag-adhesive mechanism 3 is used to blow air to cool down the welded workpiece and adhere the welding slag.

[0036] The oscillating cooling and slag-adhesion mechanism 3 includes an L-shaped arm 31 mounted on one side of the welding base 1. A sliding plate 32 is slidably connected to one side of the L-shaped arm 31, and one side of the sliding plate 32 extends into the interior of the L-shaped arm 31. A U-shaped plate 33 is fixed to one side of the sliding plate 32. An empty roller 34 is rotatably connected between opposite sides of the U-shaped plate 33. The interior of the empty roller 34 is hollow, and multiple air outlets 310 are opened on the empty roller 34. The air outlets 310 can blow out the air introduced into the empty roller 34. A guide pipe 35 is connected to one side of the empty roller 34. The guide pipe 35 rotates inside the U-shaped plate 33. One end of the guide pipe 35 passes through the U-shaped plate 33 and extends to one side of the U-shaped plate 33. A fan 36 is fixed to one side of the U-shaped plate 33. The fan 36 is controlled by an external switch and electrically connected to an external power supply. The air outlet is connected to an air outlet pipe 37. One end of the air outlet pipe 37 extends into the interior of the air guide pipe 35. After the fan 36 is started, the air outlet pipe 37 blows out air and guides it into the empty roller 34 through the air guide pipe 35. Side plates 38 are fixed on both sides of the L-shaped arm 31. Springs 39 are fixed on one side of the two side plates 38 and one side of the U-shaped plate 33. The springs 39 are used to drive the empty roller 34 to reset. When the empty roller 34 is swung by the L-shaped arm 31, the empty roller 34 moves down and contacts and squeezes the surface of the stainless steel kettle shell, causing the slide plate 32 to slide inward into the L-shaped arm 31. At the same time, the springs 39 are squeezed and compressed. After the empty roller moves up and separates from the stainless steel kettle shell, the springs 39 reset and drive the slide plate 32 to slide outward from the L-shaped arm 31. A drive assembly 4 is provided on one side of the welding base 1 to drive the L-shaped arm 31 to swing back and forth.

[0037] The drive assembly 4 includes a U-shaped frame 41 fixed to one side of the welding base 1. A rotating roller 42 is rotatably connected between opposite sides of the U-shaped frame 41. A wave groove 43 is provided on the rotating roller 42. A base plate 44 is fixed to the bottom of the U-shaped frame 41. A horizontal bar 45 is fixed to one side of the base plate 44. An L-shaped arm 31 is rotatably connected to one side of the horizontal bar 45 through a rotating shaft. When the L-shaped arm 31 swings, it reciprocates around the rotating shaft.

[0038] A connecting column 46 is fixed to one side of the L-shaped arm 31. One end of the connecting column 46 extends into the interior of the wave groove 43 and slides inside the wave groove 43. When the rotating roller 42 rotates, the wave groove 43 rotates with the rotating roller 42, thereby causing the connecting column 46 to move back and forth in the wave groove 43. In turn, the connecting column 46 drives the L-shaped arm 31 to swing up and down. A motor 47 is fixed to one side of the U-shaped frame 41. The motor 47 is controlled by an external switch and is electrically connected to an external power source. The motor 47 drives the rotating roller 42 to rotate. The output end of the motor 47 is fixed to the rotating shaft of the rotating roller 42 through a coupling.

[0039] By using the swing cooling and slag-adhesion mechanism 3, the empty roller 34 rolls in contact with the stainless steel kettle shell, causing the air outlet 310 to rotate continuously. This causes the blown air to change angle continuously and be evenly blown to one side of the stainless steel kettle shell for cooling. At the same time, when the empty roller 34 rolls in contact with the stainless steel kettle shell, it can adhere to some welding slag that is not easy to blow away, preventing the welding slag from affecting the surface smoothness of the stainless steel kettle shell after it cools down. This eliminates the need for a high-pressure blowing device, resulting in low energy consumption and high efficiency.

[0040] A cylinder 7 is fixed to one side of the welding base 1. Cylinder 7 is controlled by an external switch and electrically connected to an external power source. A locking sleeve 8 is fixed to the output end of cylinder 7. A sliding column 9 is slidably connected to the inner surface of the locking sleeve 8. A spot welding gun 10 is fixedly installed on one side of the sliding column 9. The spot welding gun 10 is existing technology. Its working principle is to apply pressure through electrodes to bring two or more workpieces into close contact, while simultaneously applying current. The resistance heat at the contact point melts the material and forms a weld spot, completing the welding. The spot welding gun 10 is controlled by an external switch and electrically connected to an external power source. A horizontal plate 11 is fixed to one side of the locking sleeve 8. A baffle 12 is fixed to the top of the horizontal plate 11. A cylinder 13 is fixed to one side of the baffle 12. Cylinder 13 is controlled by an external switch and electrically connected to an external power source. The output end of cylinder 13 is fixed to one end of the sliding column 9. A sliding groove 14 is provided on one side of the base 1, and one side of the horizontal plate 11 extends into the interior of the sliding groove 14. The dimensions of the horizontal plate 11 and the sliding groove 14 are matched, and the plate slides within the sliding groove 14. A connecting base 15 is fixed on the top of the welding station 2. A rotating column 16 is rotatably connected to the interior of the connecting base 15 via a rotary motor. A chuck 17 is fixed to one end of the rotating column 16. The rotary motor inside the connecting base 15 is controlled by an external switch and is electrically connected to an external power supply. After the rotary motor is started, it can synchronously drive the rotating column 16 and the chuck 17 to rotate. The chuck 17 is a prior art technology, specifically a four-jaw chuck. The four-jaw chuck is a commonly used workpiece clamping device, consisting of four independently movable jaws, a chuck body, and a drive mechanism. Its working principle is to clamp the workpiece from four directions by adjusting the radial position of the four jaws. It can clamp irregularly shaped workpieces such as round, square, and rectangular.

[0041] Example 2

[0042] Based on Example 1, see Figures 5-6As shown, a lifting-type stationary water spray assembly 5 is provided on the other side of the U-shaped frame 41. The lifting-type stationary water spray assembly 5 includes a vertical block 51 fixed to one side of the U-shaped frame 41, a mounting base 52 fixed to one side of the vertical block 51, an L-shaped plate 53 slidably connected inside the mounting base 52, the top and bottom of the L-shaped plate 53 extending to the outside of the mounting base 52, a roller 54 rotatably connected to one side of the L-shaped plate 53, and a folding arm 55 rotatably connected to the axle of the roller 54. The top of the folding arm 55 is provided with an inclined protruding edge. An L-shaped platform 56 is fixed to one side of the mounting base 52. The protruding edge of the folding arm 55 can be locked onto the L-shaped platform 56. A folding rod 57 is fixed to one side of the L-shaped plate 53. A square plate 58 is fixed to one end of the folding rod 57. A second spring 59 is fixed to one side of the square plate 58 and one side of the folding arm 55. The second spring 59 is used to assist the folding arm 55 in being locked onto the L-shaped platform 56. One end of the rotating shaft of the roller 42 passes through the U-shaped frame 41 and the vertical block 51 and extends to the outside of the vertical block 51. A turntable 510 is fixed to one end of the rotating shaft of the roller 42.

[0043] A lug 511 is fixed on the turntable 510. The side surface of the lug 511 contacts and presses against the side surface of the roller 54. A connecting plate 512 is fixed on one side of the turntable 510. A protruding post 513 is fixed on one side of the connecting plate 512. When the protruding post 513 rotates, its outer surface contacts and presses against one side of the folding arm 55. A support plate 514 is fixed on one side of the L-shaped plate 53. A water tank 515 is fixed on the top of the support plate 514. The water tank 515 contains clean water. A liquid hopper 516 is connected to the top of the water tank 515. External clean water is introduced into the water tank 515 through the liquid hopper 516. A horizontal pipe 517 is connected to the bottom of the water tank 515 through a conduit. Multiple nozzles 518 are connected to the bottom of the horizontal pipe 517. The nozzles 518 are controlled by an external switch and are electrically connected to an external power supply. After the nozzles 518 are started, they can spray the water in the water tank 515 in the form of water mist.

[0044] By setting up the lifting and stopping water spray component 5, water is sprayed at two positions, high and low, using the nozzle 518. It works in conjunction with the swing cooling and slag-adhesion mechanism 3. The air blown from the air outlet 310 blows the water mist onto the stainless steel kettle shell. When the water mist is sprayed at the high position, the low-density water mist covers the medium-temperature zone, slowly cooling down to balance the overall temperature and avoid local sudden cooling that could cause cracks, thus achieving initial cooling. Then, the water mist is sprayed from the low position, allowing the high-density water mist to directly act on the high-temperature zone. The water vaporization absorbs heat to quickly reduce the temperature of the weld point and prevent overheating damage. Compared with natural cooling and ordinary air cooling, this water mist combined with air blowing can achieve cooling more quickly and evenly, and can also avoid local sudden cooling after the stainless steel kettle shell is welded, thus improving the yield rate.

[0045] Example 3

[0046] Based on Example 2, see Figures 7-8As shown, an electrostatic discharge assembly 6 is provided on one side of the U-shaped frame 41. The electrostatic discharge assembly 6 includes a vertical plate 61 fixed to one side of the U-shaped frame 41. A rotating plate 63 is rotatably connected to one side of the vertical plate 61 via a rotating rod 62. A fixing plate 64 is fixed to one side of the U-shaped frame 41. A vertical tube 65 is fixed to the top of the fixing plate 64. A sliding rod 66 is slidably connected to the top of the vertical tube 65. The bottom end of the sliding rod 66 extends into the interior of the vertical tube 65.

[0047] A folding plate 67 is fixed to the top of the slide rod 66, and a spring 68 is sleeved on the slide rod 66. The spring 68 is used to drive the folding plate 67 to return to its original position. The top of the spring 68 is fixed to the bottom of the folding plate 67, and the bottom of the spring 68 is fixed to the top of the vertical tube 65. A conductive plate 69 is fixed to one side of the folding plate 67. The conductive plate 69 is made of conductive metal material and is grounded through a wire. A conductive post 610 is fixed to the bottom of the conductive plate 69. The conductive post 610 is also made of conductive metal material.

[0048] By setting up the electrostatic discharge component 6, the static electricity generated by electrode friction and air ionization during the welding of the stainless steel kettle shell is intermittently discharged, thereby effectively preventing the stainless steel kettle shell from adsorbing dust and welding slag, and further improving the surface finish.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0050] During operation, the stainless steel kettle shell is placed in chuck 17, which clamps the kettle shell. Cylinder 7 is activated, causing the spot welding gun 10 to move downwards and spot weld the kettle shell. A rotary motor rotates chuck 17 and the kettle shell, changing their orientation. Motor 47 is activated, causing roller 42 to rotate. The corrugated groove 43 on roller 42 rotates accordingly, causing connecting column 46 to slide left and right within the groove. This causes L-arm 31 to swing downwards. As L-arm 31 swings downwards, empty roller 34 moves downwards. Fan 36 is activated. Air is blown into the empty roller 34 and discharged through the air outlet 310 onto the stainless steel kettle shell for cooling. As the empty roller 34 swings, the blowing angle can be continuously adjusted. After the empty roller 34 contacts the stainless steel kettle shell, it rolls and adheres to the welding slag that is difficult to blow off the stainless steel kettle. At the same time, the sliding plate 32 slides into the L-shaped arm 31 and squeezes and compresses the first spring 39. When the rotating roller 42 rotates, it synchronously drives the turntable 510 to rotate. Then, when the turntable 510 rotates, it drives the lug 511 to contact and squeeze the roller 54. The roller 54 drives the L-shaped plate 53 to move upward, which in turn drives the folding arm 55 to move upward. The elastic force of the second spring 59 drives the protruding edge of the folding arm 55. The nozzle 518 is positioned on the L-shaped platform 56. At this point, the L-shaped plate 53 moves the nozzle 518 upwards and holds it for a period of time. The nozzle 518 then activates, spraying water mist. This mist, combined with the airflow from the air outlet 310, propels the low-density water mist around the stainless steel kettle's outer casing, achieving initial cooling. When the protruding post 513 rotates to contact the folding arm 55, it drives the folding arm 55 to rotate, which in turn compresses the second spring 59. At this point, the folding arm 55 separates from the L-shaped platform 56. The L-shaped plate 53 then moves downwards under gravity, causing the nozzle 518 to move downwards and hold for a period of time. During this time, the water mist sprayed by the nozzle 518 is closer to the air outlet 310. High-density water mist is blown around the stainless steel kettle shell. At this time, the water mist is closer to the stainless steel kettle shell, which can deeply cool and clean it. When the protrusion 513 rotates, it contacts the rotating plate 63, which in turn drives the rotating plate 63 to rotate. The rotating plate 63 squeezes and compresses the folding plate 67, which in turn squeezes the slide rod 66 and the spring 68. The folding plate 67 then drives the conductive plate 69 and the conductive post 610 to contact the stainless steel kettle shell, dissipating the static electricity on the stainless steel kettle shell and preventing dust and welding slag from adhering to the stainless steel kettle shell due to static electricity. After the protrusion 513 separates from the rotating plate 63, the spring 68 returns to its original position, causing the conductive post 610 to separate from the stainless steel kettle shell.

[0051] The embodiments of the invention have been described in detail above, but the content described is only a preferred embodiment of the invention and should not be considered as limiting the scope of the invention. All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
