[0020] 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.

[0021] Please see Figures 1 to 12 This invention provides a technical solution: a welding device for automotive body reinforcing plate nuts, comprising a movable base 1, four first electric telescopic columns 2 fixed on the upper surface of the movable base 1, a support platform 3 fixed on the top of the four first electric telescopic columns 2, a cooling box 4 fixed on one side of the upper surface of the support platform 3, a bracket 9 fixed on the other side of the upper surface of the support platform 3, a welding and cooling mechanism 13 provided on the top of the bracket 9, the welding and cooling mechanism 13 comprising a rotating cylinder 1301, the rotating cylinder 1301 being rotatably connected to the top of the bracket 9, a straight pipe 1309 fixed at the bottom of the rotating cylinder 1301, a first exhaust pipe 1319 slidably connected to one end of the straight pipe 1309, a welding gun 1320 fixed at the bottom of the first exhaust pipe 1319, an exhaust channel 1321 fixed at the beginning of the first exhaust pipe 1319, a second blowing pipe 1330 slidably connected to the other end of the straight pipe 1309, and a blower head 1331 fixed at the bottom of the second blowing pipe 1330.

[0022] In this embodiment, as Figure 1 As shown, the top of the cooling tank 4 is threaded with a plug 5, and an electric drain valve 6 is fixed on one side of the cooling tank 4. After unscrewing the plug 5, coolant can be introduced into the cooling tank 4 to facilitate the cooling of hot air. After opening the electric drain valve 6, the coolant can be discharged.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 9As shown, two ventilation ducts 7 are rotatably connected to the cooling box 4, and both ventilation ducts 7 penetrate the cooling box 4. A first gear 8 is fixed to the outer side of one end of the ventilation duct 7. A first motor 10 is fixed to one side of the bracket 9, and the output end of the first motor 10 is connected to the belt drive assembly 17. An internal gear disk 11 is fixed to one side of the belt drive assembly 17, and the internal gear disk 11 is rotatably connected to the other side of the cooling box 4. Both first gears 8 are meshed with the inner wall of the internal gear disk 11, and a first through hole 12 is evenly opened on one side of the internal gear disk 11. During the use of the coolant in the cooling box 4, the air flows through the two ventilation ducts 7, which facilitates the removal of heat from the coolant and achieves the heat dissipation effect. At the same time, the belt drive assembly 17 can operate under the action of the first motor 10, thereby driving the internal gear disk 11 to rotate, which in turn drives the two first gears 8 to rotate, and the two ventilation ducts 7 to rotate accordingly, making the heat dissipation effect more comprehensive and uniform.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, two first protruding rings 1302 are fixed on the outer side of the rotating drum 1301. The top of the bracket 9 is located between the two first protruding rings 1302. A gear ring 1303 is fixed on the outer side of the rotating drum 1301. A second motor 1304 is fixed on the inner top of the bracket 9. The output end of the second motor 1304 is connected to the second gear 1305. The gear ring 1303 is meshed with one side of the second gear 1305. The second gear 1305 can rotate under the action of the second motor 1304. Since the second gear 1305 is meshed with the gear ring 1303, the rotating drum 1301 can rotate with the rotation of the second gear 1305. The bracket 9 and the two first protruding rings 1302 are used together to support and limit the rotating drum 1301.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, two second protruding rings 1306 are fixed on the outer side of the rotating drum 1301, and a third gear 1307 is rotatably connected to the outer side of the rotating drum 1301. The third gear 1307 is located between the two second protruding rings 1306, and the third gear 1307 is fixed to one of the second protruding rings 1306 by fasteners 1308. During the pushing and pulling of the first exhaust pipe 1319 and the second blower pipe 1330, the third gear 1307 rotates. After adjusting the position of the welding gun 1320 and the blower head 1331, the fasteners 1308 are tightened to lock the third gear 1307, and the first exhaust pipe 1319 and the second blower pipe 1330 are fixed. The two second protruding rings 1306 play a supporting and limiting role for the third gear 1307.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, a heat insulation cylinder 1322 is fixed to the inner top of the rotating cylinder 1301, and a connecting pipe 1323 is fixed to one side of the rotating cylinder 1301. A fixing frame 1325 is fixed to the top of the support 9, and a first annular pipe 1324 is fixed to the inner side of the fixing frame 1325. The connecting pipe 1323 is rotatably connected to the inner wall of the first annular pipe 1324. A second exhaust pipe 14 and a second exhaust pipe 18 are fixed to the top of the cooling box 4, and the first end of the second exhaust pipe 14 passes through one side of the fixing frame 1325 and is connected to the first annular pipe 1324. A first exhaust pipe 1326 is fixed to the top of the fixing frame 1325, and the first exhaust pipe 1326 passes through the rotating cylinder 1301, the heat insulation cylinder 1322, and the straight pipe 1309. 26 is fixed at the end of the second exhaust pipe 18, and the side of the bottom of the first exhaust pipe 1326 is uniformly provided with second through holes 1327. High-temperature fumes are generated during the welding process of the nut using the welding gun 1320. The exhaust channel 1321 sucks away the fumes. The fumes pass through the first exhaust pipe 1319 and the straight pipe 1309 in sequence and enter between the rotating cylinder 1301 and the heat insulation cylinder 1322. Then the fumes enter the first annular pipe 1324 through the connecting pipe 1323 and enter the cooling box 4 through the second exhaust pipe 14. The coolant can cool the high-temperature fumes, and the impurities in the fumes will remain in the coolant, which can achieve the effect of automatic impurity removal. The cooled fumes are discharged through the second exhaust pipe 18 and enter the first exhaust pipe 1326.

[0027] In this embodiment, as Figure 3 , Figure 4 , Figure 6 and Figure 12As shown, a second annular pipe 1328 is fixed to the inner bottom of the straight pipe 1309, and the second annular pipe 1328 is rotatably connected to the outside of the first exhaust pipe 1326. A first air blowing pipe 1329 is fixed to one side of the second annular pipe 1328, and the first air blowing pipe 1329 extends into the second air blowing pipe 1330. The first air blowing pipe 1329 and the second air blowing pipe 1330 form a telescopic structure. After the cooled flue gas enters the first exhaust pipe 1326, it will pass through the second through hole 1327 and enter the second annular pipe 1328. Then the cold air passes through the first air blowing pipe 1329 and the second air blowing pipe 1330 and is blown out, which facilitates the cooling of the welding position of the nut.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the bottom of the first exhaust pipe 1326 is connected to the circular plate 1311 via the second electric telescopic column 1310. A worm gear 1312 is rotatably connected to the inner side of the circular plate 1311. The worm gear 1312 passes through one side of the circular plate 1311 and is connected to the knob 1313. A worm wheel 1314 is meshed with the front side of the worm gear 1312. A rotating frame 1315 is fixed to the bottom of the worm wheel 1314 and rotatably connected to the bottom of the circular plate 1311. Four first toothed plates 1316 are evenly fixed to the outer circumference of the rotating frame 1315. Four pressure plates 1317 are evenly rotatably connected to the bottom circumference of the circular plate 1311. A rack 1318 is evenly fixed to one end of each pressure plate 1317. 8. Engagement connection with the outer side of the first toothed plate 1316. After placing the nut in the welding position, position the round plate 1311 directly above the nut. Hold the knob 1313 and rotate the worm gear 1312, thereby driving the worm wheel 1314 to rotate. The rotating frame 1315 and the four first toothed plates 1316 rotate accordingly. Since the first toothed plate 1316 is engaged with the rack 1318, the four pressure plates 1317 rotate and open. The degree of opening of the pressure plates 1317 can be determined according to the outer diameter of the nut, ensuring that the pressure plates 1317 can press the nut while not exceeding the edge of the nut. Then, the round plate 1311 moves downward under the extension of the second electric telescopic column 1310, and the four pressure plates 1317 can press and fix the nut.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, both sides of the straight pipe 1309 are fixed with limiting sleeves 1332, and each of the two limiting sleeves 1332 has a second toothed plate 1333 passing through it. The two second toothed plates 1333 are respectively meshed and connected to both sides of the third gear 1307. When the first exhaust pipe 1319 or the second blower pipe 1330 is pushed or pulled, the corresponding second toothed plate 1333 moves. At this time, the third gear 1307 rotates and drives the other second toothed plate 1333 to move. The two second toothed plates 1333 move in opposite directions, which makes it convenient to adjust the position of the welding gun 1320 and the blower head 1331 according to the size of the nut. The limiting sleeves 1332 play a supporting and limiting role during the movement of the second toothed plate 1333.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a support cylinder 15 is fixed on the second exhaust duct 14, and a fan 16 is rotatably connected inside the support cylinder 15. The fan 16 is connected to the output end of the belt drive assembly 17. The operation of the belt drive assembly 17 can drive the fan 16 to rotate. The fan 16 exhausts air to the left, which facilitates the extraction of high-temperature flue gas into the coolant.

[0031] The method of use and advantages of this invention: The working process of this automotive body reinforcement plate nut welding equipment is as follows: like Figures 1 to 12As shown: Unscrew the plug 5 and fill the cooling box 4 with coolant, then screw the plug 5 back on. First, place the nut on the reinforcing plate, raise the support platform 3, and use the movable seat 1 to move the device to the desired location so that the circular plate 1311 is directly above the nut. Connect to the external power supply and manually push or pull the first exhaust pipe 1319 or the second blower pipe 1330. The corresponding second toothed plate 1333 moves, and the other second toothed plate 1333 moves under the rotation of the third gear 1307. The two second toothed plates 1333 move closer or further apart. After adjusting the positions of the welding gun 1320 and the blower head 1331, tighten the fastener 1308. This locks the third gear 1307. Then, the support platform 3 is lowered, and the welding gun 1320 is aligned with the welding point, maintaining a suitable distance between it and the welding point. The worm gear 1312 is rotated by holding knob 1313, causing the worm wheel 1314, rotating frame 1315, and four first toothed plates 1316 to rotate as a whole. The four pressure plates 1317 rotate and open. Then, the circular plate 1311 moves down, and the four pressure plates 1317 press against the top of the nut, ensuring they do not exceed the edge of the nut. The welding gun 1320 is activated, and the second gear 1305 rotates, causing the rotating drum 1301 and straight tube 1309 to rotate. The welding gun 1320 then surrounds the nut. After the welding is completed, the drive assembly 17 rotates, driving the fan 16 to rotate. The fan 16 draws air to the left, and the exhaust duct 1321 sucks away the high-temperature fumes. The fumes pass sequentially through the first exhaust duct 1319, straight pipe 1309, rotating cylinder 1301, connecting pipe 1323, first annular pipe 1324, and second exhaust duct 14 into the coolant. The coolant cools the fumes, and impurities in the fumes remain in the coolant. The cooled fumes are discharged through the second exhaust duct 18 and sequentially pass through the first exhaust duct 1326, second through hole 1327, second annular pipe 1328, first blowing duct 1329, and second blowing duct. The air blows out from the pipe 1330 and the blower head 1331. The blower head 1331 blows air around the nut to facilitate cooling of the weld. The air travels through the two ventilation pipes 7, which can carry away the heat in the coolant. At the same time, the drive assembly 17 drives the internal gear disk 11 to rotate, and the two first gears 8 rotate, thereby driving the two ventilation pipes 7 to rotate, which facilitates comprehensive and uniform heat dissipation. After the welding cooling operation is completed, the circular plate 1311 is raised, the nuts of the pressure plate 1317 are loosened, the knob 1313 is rotated in the opposite direction to retract the four pressure plates 1317, then the first exhaust pipe 1319 and the second blower pipe 1330 are reset, and finally the support platform 3 is raised and the device is removed.

[0032] In summary, this automotive body reinforcement plate nut welding equipment achieves the goals of positioning, clamping and fixing, cooling, automatic impurity removal, and uniform heat dissipation, thus meeting people's usage needs.
