Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to a high-efficiency intelligent welding device for mechanical processing. Background Art

[0002] Welding is a process that melts metal parts locally by heating them, and then permanently connects them together after cooling. When welding metal parts, the heated part will melt quickly, but a small amount of molten metal may adhere to the surface of the welding head. After the welding is completed, as the coolant cools the welding head, the molten metal attached to its surface can cool and solidify into welding slag. The presence of welding slag will increase the wear and resistance of the electrode during subsequent welding, and may further increase energy consumption and reduce welding quality. Frequent manual cleaning is time-consuming and not conducive to improving production efficiency. In addition, during welding, molten metal and flux will produce pungent odors at high temperatures, which also poses a certain threat to the health of nearby workers. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0032] Example: As attached Figure 1-13 As shown, the present invention is a highly efficient intelligent welding device for mechanical processing, comprising:

[0033] A workbench 1, which is used to provide a basic support surface;

[0034] A vertical plate 4, the outer side of the vertical plate 4 is fixedly connected to the middle part of the workbench 1, a servo motor 5 is fixedly connected to the bottom of the rear end of the vertical plate 4, a turntable 6 is fixedly connected to the output end of the servo motor 5, a convex rod 7 is fixedly connected to the rear end of the turntable 6, a connecting plate 8 is arranged on the outer side of the convex rod 7, a rotating rod 9 is fixedly connected to the top of the front end of the connecting plate 8, the front end of the rotating rod 9 penetrates the vertical plate 4 and is fixedly connected to a gear 10, the front end of the gear 10 is rotatably connected to a limiting frame 11, the upper and lower sides of the limiting frame 11 are slidably connected to a spot welding head 12, both sides of the gear 10 are meshed with a rack 13, the rear ends of the upper and lower spot welding heads 12 are fixedly connected to the front end of the rack 13, and the middle of the front end of the limiting frame 11 is fixedly connected to a U-shaped frame 14, the front parts of the upper and lower ends of the U-shaped frame 14 are rotatably connected with a cleaning bin 15, the inner parts of the upper and lower cleaning bins 15 are slidably connected with a plurality of sliders 16 on the sides close to each other, and the plurality of sliders 16 are fixedly connected with a grinding wheel brush 17 on the side away from the cleaning bin 15, the rear parts of the upper and lower ends of the U-shaped frame 14 are slidably connected with an L-shaped bracket 18, the rear parts of the upper and lower L-shaped brackets 18 on the sides away from each other are rotatably connected with a rotating wheel 19, the front parts of the upper and lower L-shaped brackets 18 on the sides away from each other are rotatably connected with a rotating plate 20, and the ends of the upper and lower rotating plates 20 away from the rotating wheel 19 are rotatably connected to one side of the rear end of the cleaning bin 15, and the rear parts of the upper and lower spot welding heads 12 on the sides close to each other are fixedly connected with a wavy push plate 21.

[0035] The servo motor 5 can be supported by the vertical plate 4, so that the servo motor 5 can drive the turntable 6 to rotate stably. At this time, the protruding rod 7 located at the eccentric part of the rear surface of the turntable 6 can apply left and right thrust to the connecting plate 8 during rotation. Since the connecting plate 8 is restricted by the vertical plate 4 and the rotating rod 9, the connecting plate 8 can reciprocate to a certain extent with the rotating rod 9 as the center. The movement can be further transmitted to the gear 10 through the rotating rod 9, so that the gear 10 reciprocates and drives the spot welding head 12 and its energized part to move closer to or away from each other along the limit frame 11 through the rack 13 meshing with it, so as to achieve the purpose of welding metal parts transported to the area between the spot welding heads 12 by external conveying equipment. In addition, when the spot welding head 12 moves, the wavy push plate 21 connected to its shell can move synchronously. When near the area where the grinding wheel brush 17 is located, the wavy push plate 21 can contact the rotating wheel 19, so that the rotating wheel 19 can drive the L-shaped bracket 18 to move forward along the U-shaped frame 14 by utilizing the curvature of the surface of the wavy push plate 21. At this time, the rotating plate 20 connected to the L-shaped bracket 18 rotates due to its fixed length, thereby pushing the cleaning chamber 15 to rotate a certain angle along the surface of the U-shaped frame 14, and the slider 16 located inside the cleaning chamber 15 can drive the evenly distributed grinding wheel brushes 17 to scrape the metal liquid that may be attached to the surface of the welding area of ​​the spot welding head 12 when the spot welding head 12 passes through the cleaning chamber 15, so as to prevent it from cooling and solidifying into welding slag, and further prevent it from increasing electrode wear and resistance during subsequent welding, thereby achieving the purpose of reducing energy consumption and improving welding quality, and no manual regular cleaning is required, thereby improving the overall processing efficiency.

[0036] As attached Figure 1 , Attachment Figure 4 and attached Figure 5 The outer front end of the turntable 6 is rotatably connected to a support ring 22, the front end of the support ring 22 is fixedly connected to the rear end of the vertical plate 4, the rear end of the gear 10 is rotatably connected to the middle part of the front end of the vertical plate 4, the upper and lower sides of the rear end of the limit frame 11 are fixedly connected to the front end of the vertical plate 4, and the rear end of the rack 13 is slidably connected to both sides of the front end of the vertical plate 4.

[0037] The support ring 22 can be used to fix the turntable 6 to prevent it from shaking when rotating and causing excessive shear force on the output end of the servo motor 5. The vertical plate 4 can be used to limit the gear 10 and the rack 13 to prevent them from deviating from the predetermined trajectory, thereby ensuring that the gear 10 and the rack 13 can be effectively engaged.

[0038] As attached Figure 6 and attached Figure 8 The upper and lower spot welding heads 12 are both facing the cleaning bin 15, and multiple sliders 16 are fixedly connected to the side close to the cleaning bin 15 with springs 23, and the ends of multiple springs 23 away from the sliders 16 are fixedly connected to the inside of the cleaning bin 15, and multiple limit rods 24 are passed through the upper and lower cleaning bins 15, and the ends of multiple limit rods 24 close to each other are fixedly connected to the ends away from the sliders 16, and multiple springs 23 are wrapped around the outside of the limit rods 24.

[0039] By having the spot welding head 12 facing the cleaning chamber 15, it can be ensured that the spot welding head 12 can be acted upon by the grinding wheel brush 17, and by using the spring 23, the grinding wheel brush 17 can be effectively contacted with the spot welding head 12, thereby improving the scraping effect, and the movement direction of the slider 16 and the grinding wheel brush 17 can be limited by the limit rod 24 to prevent the grinding wheel brush 17 from deviating from the predetermined trajectory and overlapping, and further avoid the grinding wheel brush 17 from being unable to fully contact the spot welding head 12. In addition, when the spot welding heads 12 contact each other, their outer frustum-shaped shells can contact the grinding wheel brush 17 to push the grinding wheel brush 17 and the slider 16 to overcome the thrust applied by the spring 23 and approach the inner wall of the cleaning chamber 15 along the limit rod 24, thereby avoiding the grinding wheel brush 17 from still contacting the electrode area of ​​the spot welding head 12 after power is supplied to it.

[0040] As attached Figure 8 and attached Fig. 9 The upper and lower L-shaped brackets 18 are fixedly connected with trapezoidal blocks 25 on both sides, the front parts of the top ends of the multiple trapezoidal blocks 25 are slidably connected with trapezoidal blocks 26, and the front parts of the multiple trapezoidal blocks 26 are penetrated by guide frames 27, and the guide frames 27 are fixedly connected to the upper and lower ends of the U-shaped frame 14 at one end.

[0041] The moving direction of the trapezoidal block 26 can be restricted by the guide frame 27, and the trapezoidal block 26 can apply a thrust to the trapezoidal block 25 through the inclined surface in contact with the trapezoidal block 25 by utilizing its own weight. Moreover, since the trapezoidal block 25 is connected to the L-shaped bracket 18, the L-shaped bracket 18 can always have a tendency to move backward under the action of the deadweight of the trapezoidal block 26, thereby ensuring that the rotating wheel 19 can move forward and backward along the curvature of its surface when the wavy push plate 21 moves, so that the cleaning chamber 15 can drive the slider 16 and the grinding wheel brush 17 to rotate back and forth through the deflection of the rotating plate 20, thereby further improving the cleaning effect of the grinding wheel brush 17 on the metal liquid that is about to solidify into welding slag on the surface of the spot welding head 12.

[0042] As attached Figure 2 , Attachment Figure 6 , Attachment Figure 7 , Attachment Fig.11 and attached Fig.12 , a suction mechanism 2, which is arranged on both sides of the front of the workbench 1 and is used to process the gas generated by welding;

[0043] The suction mechanism 2 includes a treatment cylinder 201, the outer sides of the treatment cylinder 201 are respectively fixedly connected to the two sides of the front part of the workbench 1, a transmission rod 202 is passed through the middle of the treatment cylinders 201 on both sides, and the outer tops of the transmission rods 202 on both sides are fixedly connected to impellers 203, the inner lower parts of the treatment cylinders 201 on both sides are fixedly connected to orifice plates 204, and the inner bottoms of the treatment cylinders 201 on both sides are provided with a plurality of exhaust holes 205, the bottom ends of the treatment cylinders 201 on both sides are fixedly connected to drive bins 206, and the insides of the drive bins 206 on both sides are rotatably connected to impellers 207, and the middle parts of the impellers 207 on both sides are fixedly connected to the outer bottoms of the transmission rods 202, and the drive bins 206 on both sides are fixedly connected to the outer bottoms of the transmission rods 202. 06 is provided with an exhaust hole 208 at the front of the bottom end, and the rear ends of the driving compartments 206 on both sides are fixedly connected to the exhaust pipes 209, and the top rear part of the workbench 1 is fixedly connected to the cooling pool 210, and the rear ends of the exhaust pipes 209 are respectively fixedly connected to the upper parts of the two sides of the front end of the cooling pool 210, and the bottom end of the cooling pool 210 is fixedly connected to the S-shaped pipe 211, and the lower part of one side of the front end of the cooling pool 210 is fixedly connected to the pump body 212, and the upper and lower spot welding heads 12 are fixedly connected to the cooling pipe 213, and one side of the rear end of the cooling pipe 213 is arranged inside the pump body 212, and the other side of the rear end of the cooling pipe 213 is fixedly connected to the lower part of the front end of the cooling pool 210 away from the pump body 212.

[0044] The S-shaped tube 211 can increase the contact time between the internal coolant and the cooling water in the cooling pool 210, thereby ensuring that the coolant has effectively recovered to normal temperature when it is pumped into the cooling pipe 213 by the pump body 212. It can further ensure that the coolant can promptly remove the heat inside the spot welding head 12 when flowing through the cooling pipe 213 inside the spot welding head 12, preventing the high temperature generated after the spot welding head 12 is powered on from accumulating inside the spot welding head 12 for a long time and causing overheating and damage to the spot welding head 12. After the heat is exchanged to the cooling water, the copper cooling pool 210 can be used to increase the heat dissipation area. In addition, part of the heated and boiling cooling water can also generate water vapor, which is discharged to the rear continued area in the drive compartment 206 under the connection with the exhaust pipe 209. Since the internal space of the drive compartment 206 is limited, and all the water vapor is discharged to the exhaust hole 202 through the exhaust hole 209. 8 is located at the front bottom end of the driving bin 206, so the water vapor can apply thrust to the impeller 207 when being discharged, so that the impeller 207 drives the transmission rod 202 and the impeller 1 203 to rotate, and then with the rotation of the impeller 1 203, the irritating air generated by the spot welding head 12 during welding can be sucked into the treatment tube 201, so that the air is adsorbed and treated by the activated carbon and other substances above the orifice plate 204, and the purified air can be discharged to the outside through the tiny holes on the surface of the orifice plate 204 and the exhaust holes 1 205 evenly distributed below the orifice plate 204, thereby achieving the purpose of purifying the air and protecting nearby staff, and no additional driving source is required, which can save energy to a certain extent. In addition, the cooling pipe 213 needs to be reserved for a sufficient length in actual use to prevent it from restricting the normal movement of the spot welding head 12.

[0045] As attached Fig.11 and attached Fig.12 The middle parts of the orifice plates 204 on both sides are rotatably connected to the outside of the transmission rod 202, the tops of the orifice plates 204 on both sides are fixedly connected with annular plates 215, the inner sides of the annular plates 215 on both sides are rotatably connected to the outside of the transmission rod 202, the upper outer parts of the transmission rods 202 on both sides are rotatably connected with cross plates 214, the outer sides of the cross plates 214 on both sides are fixedly connected to the upper inner part of the processing cylinder 201, and the middle parts of the two sides of the processing cylinders 201 away from each other are hinged with arc plates 216.

[0046] The contact between the orifice plate 204 and the transmission rod 202 can prevent substances such as activated carbon from falling directly to the bottom of the treatment cylinder 201, and the annular plate 215 can prevent the transmission rod 202 from colliding with the activated carbon when rotating. At the same time, by opening the arc plate 216, the activated carbon above the orifice plate 204 can be replaced regularly to avoid affecting the treatment effect of the irritating air. In addition, the cross plate 214 can be used to limit the transmission rod 202 to prevent the transmission rod 202 from shaking when rotating.

[0047] As attached Figure 3 , Attachment Fig.10 and attached Fig.13A water inlet mechanism 3 is arranged at the rear of the top end of the workbench 1 and is used to control the cooling water level.

[0048] The water inlet mechanism 3 includes a hollow floating plate 301, which is arranged at the rear part of the cooling pool 210. The top of the hollow floating plate 301 is rotatably connected to a rotating plate 2 302, and the top of the rotating plate 2 302 is rotatably connected to a baffle 303. The top of the baffle 303 is slidably connected to the rear part of the top of the workbench 1, and a water inlet hole 304 is opened at the rear part of the workbench 1. Guide rods 305 are fixedly connected to both sides of the upper part of the cooling pool 210, and multiple connecting blocks 306 are slidably connected to the outer sides of the guide rods 305 on both sides. The tops of the connecting blocks 306 are respectively fixedly connected to the four corners of the bottom end of the baffle 303. Guide frames 2 307 are passed through both sides of the hollow floating plate 301. The upper and lower sides of the rear ends of the guide frames 2 307 on both sides are fixedly connected to the rear end of the cooling pool 210, and transparent observation ports 308 are opened on both sides of the cooling pool 210.

[0049] The hollow floating plate 301 can be limited by the guide frame 307 to prevent the hollow floating plate 301 from lateral displacement with the change of water level, and the guide rod 305 and the connecting block 306 can be used to limit the movement direction of the baffle 303. When the water level of the cooling water in the cooling pool 210 drops due to evaporation, the hollow floating plate 301 can move down accordingly, and the rotating plate 302 connected to the hollow floating plate 301 has a fixed length, so it can rotate with the cooperation of the guide rod 305 and the connecting block 306 to pull the baffle 303 backward, and after the baffle 303 moves a certain distance, it no longer blocks the water inlet hole 304, and The external water supply pipe connected to the water inlet hole 304 can inject cooling water into the cooling pool 210 in time to make up for the water loss due to evaporation, and avoid too little cooling water affecting the cooling effect of the S-shaped tube 211. As the water level recovers, the hollow floating plate 301 can push the baffle 303 back through the rotating plate 302, so that when the water level reaches a certain height, the baffle 303 can be used to block the water inlet hole 304 again to avoid the water level being too high and causing the cooling water to enter the drive compartment 206 through the exhaust pipe 209, thereby achieving the purpose of actively controlling the water level. In addition, the transparent observation port 308 can facilitate the staff to actively check the internal situation of the cooling pool 210.

[0050] As attached Fig.10 and attached Fig.13 The front end of the hollow floating plate 301 is fixedly connected with an indicator plate 309, the upper part of the indicator plate 309 passes through the workbench 1, and both sides of the indicator plate 309 are slidably connected with scale plates 310, and the bottom ends of the scale plates 310 on both sides are fixedly connected to the rear part of the top of the workbench 1.

[0051] The movement direction of the indicator plate 309 can be restricted by the scale plate 310 to prevent the indicator plate 309 from shaking when moving with the hollow floating plate 301. At the same time, the scale value on the surface of the scale plate 310 can facilitate the staff to understand the actual height of the hollow floating plate 301 through the indicator plate 309, and then the actual remaining water volume inside the cooling pool 210 can be grasped in real time, so that the staff can use the spot welding head 12 with confidence.

[0052] Working principle: When in use, the metal parts to be welded are continuously transported to the middle area of ​​the upper and lower spot welding heads along the guide frame on the surface of the workbench through external conveying equipment. At this time, the servo motor is started, so that the turntable can drive the convex rod at the eccentric part of its surface to rotate, and under the restriction of the vertical plate and the rotating rod, the connecting plate in contact with the convex rod can be forced to swing, and then react to the rotating rod, so that the rotating rod can drive the gear to rotate reciprocatingly. At this time, the rack meshing with the two sides of the gear can make reciprocating linear motion along the vertical plate, so as to drive the spot welding head to approach the metal parts to be welded under the restriction of the limit frame. When the spot welding head is energized and the welding is completed, the reciprocating rack drives the spot welding head to return after the power is turned off, thereby reserving transportation time for the subsequent metal parts to be welded, and because the trapezoidal block 2 can pass through under the action of gravity The inclined surface applies thrust to the trapezoidal block 1, and the trapezoidal block 1 is connected to the rotating wheel through the L-shaped bracket. Therefore, the rotating wheel can approach the limit frame when not pushed by external force. At the same time, the wavy push plate connected to the spot welding head and capable of moving synchronously therewith can contact the rotating wheel after moving a certain distance, so that the rotating wheel can move forward and backward along the curvature of the surface of the wavy push plate under the joint action of the wavy push plate and the trapezoidal block 2, so that the L-shaped bracket can have the same movement trend. Due to the restriction that the length of the rotating plate 1 is fixed, the rotating plate 1 can rotate when the L-shaped bracket moves, thereby pushing the cleaning chamber to drive the grinding wheel brush to rotate a certain angle through the slider, and as the rotating wheel moves backward, the rotating plate 1 can drive the grinding wheel brush to reverse through the cleaning chamber and the slider, so that when the spot welding head passes through the inner side of the grinding wheel brush, the grinding wheel brush can be used to The surface of the spot welding head is repeatedly scraped to achieve the purpose of timely cleaning the welding slag on the surface of the spot welding head, preventing the welding slag from affecting the resistance value and temperature change of the subsequent spot welding head when used, avoiding the need to manually suspend processing and manually remove the welding slag, thereby improving the processing efficiency. When the spot welding heads are close to each other for welding operations, the truncated cone-shaped shell on the surface of the spot welding head can push the grinding wheel brush and the slider to overcome the thrust applied by the spring, thereby moving away from the spot welding head to avoid the grinding wheel brush from contacting the spot welding head after power is turned on. Conversely, when the spot welding head is powered off and the truncated cone-shaped shell on its surface is separated from the grinding wheel brush, the slider and the grinding wheel brush can be pushed by the spring to contact the spot welding head, thereby ensuring the quality of the scraping. In addition, the spot welding head can generate a high temperature of hundreds of degrees when powered on, and the coolant inside the cooling tube can be used to timely cool the spot welding head. The heat from the inside is taken away to prevent the spot welding head from being damaged due to long-term high temperature. The S-shaped tube connected to the cooling pipe can increase the time that the coolant is acted upon by the cooling water inside the cooling pool, ensuring that the coolant has recovered to normal temperature when it is discharged from the inside of the S-shaped tube. Under the action of the pump body, the coolant can continue to enter the spot welding head through the cooling pipe to complete the cycle. The heated cooling water inside the cooling pool can further increase the heat dissipation area through the copper cooling pool. At this time, the heated cooling water can also generate high-temperature steam. The exhaust pipe is used to allow air to continuously enter the rear area of ​​the driving compartment. As the air pressure inside the driving compartment increases, the air can drive the second impeller to rotate and be discharged to the outside through the second exhaust hole at the front bottom of the driving compartment. At the same time, the transmission rod can also drive the first impeller to rotate.Thus, the irritating air generated when the spot welding head welds metal parts is continuously sucked into the treatment cylinder, and then adsorbed by the activated carbon and other substances above the orifice plate. The treated air can pass through the orifice plate through the tiny holes on the surface of the orifice plate, and then be discharged to the outside along the evenly distributed exhaust holes, so as to prevent nearby workers from inhaling excessive irritating odors and affecting their health. In addition, as the cooling water inside the cooling pool evaporates, the water level can gradually drop, so that the hollow floating plate can drive the rotating plate 2 to move down along the guide frame 2. Since the length of the rotating plate 2 is fixed, it can rotate and pull the baffle to move backward along the guide rod and the connecting block, so as not to block the water inlet hole. Further, the cooling water from the outside can be actively injected into the cooling pool to prevent the S-shaped pipe from being unable to be effectively cooled down due to insufficient cooling water. As the water level inside the cooling pool rises, the rotating plate 2 and the baffle can move in the opposite direction to prevent excessive cooling water from entering the drive compartment along the exhaust pipe, thereby achieving the purpose of self-control of the water level.
