DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 6 As shown, a welding device for producing anti-theft doors according to an embodiment of the present invention comprises a workbench 1; a protective frame 11 is fixedly connected to the side wall of the workbench 1; first slide rails 21 are symmetrically fixedly connected to the top of both ends of the workbench 1, a movable frame 2 is slidably connected to the two first slide rails 21, a second slide rail 22 is fixedly connected to the bottom of the movable frame 2, a sliding seat 221 is slidably connected to the second slide rail 22, a welding gun 223, a visual sensor 23 and a dust hood 24 are respectively provided below the sliding seat 221; a processing mechanism is provided on the dust hood 24; the processing mechanism comprises a hollow cylinder 241 fixedly connected to the top of the dust hood 24; a hollow cylinder 241 is provided inside the hollow cylinder 241 A rotating rod 243 is rotatably connected to the mounting frame, and a cyclone blade 244 is fixed to the rotating rod 243. A first gear 245 is fixed to the top of the rotating rod 243, and a first motor 247 is fixed to the top of the hollow cylinder 241. The output shaft of the first motor 247 is rotatably connected to the hollow cylinder 241 through a bearing and is fixed to a second gear 246, and the second gear 246 is engaged with the first gear 245; the top of the hollow cylinder 241 is connected and fixed with a dust suction pipe 26, and the top of the movable frame 2 is fixed with a collecting box 261, one end of the dust suction pipe 26 is connected and fixed to the collecting box 261, and a fan 262 is installed on the dust suction pipe 26.

[0023] When welding security doors, the steel components of the security doors need to be fixed first, and then metal cutting and welding equipment are used to manufacture them. Welding slag will be generated during the welding process. If the welding is not cleaned in time, the slag splashing will not only lead to a bad welding environment, but also the slag splashing to the connection of the transmission components, thereby causing the security door to be unstable and reducing the welding quality.

[0024] When the processing mechanism provided by the present invention is in use, it monitors the route of the welding gap of the anti-theft door through the visual sensor 23, and then transmits the route data to the computer system. According to the setting and planning of the route by the computer system, the welding gun 223 is driven to move to a suitable route for welding through the first slide rail 21 and the second slide rail 22. During the welding process, by turning on the fan 262, the fan 262 forms a negative pressure at the entrance of the dust hood 24, and absorbs the welding smoke and welding slag generated by welding through the negative pressure adsorption. The welding smoke and welding slag are sucked into the dust suction pipe 26 through the dust suction hood 24, and finally fall into the collection box 261 from the other end of the dust suction pipe 26. Since some sparks in the welding slag are absorbed before they can be extinguished, if the sparks are not processed The entry of sparks may burn the dust collection pipe 26 and the fan 262, so the first motor 247 needs to be turned on during cleaning. The first motor 247 drives the second gear 246 to rotate through the output shaft, drives the first gear 245 to rotate through the second gear 246, drives the rotating rod 243 to rotate through the first gear 245, and drives the cyclone blades 244 to rotate through the rotating rod 243. The absorbed welding slag is cycloned by the cyclone blades 244, so that the welding is centrifuged on the wall of the hollow cylinder 241, part of which will be sucked into the collection box 261, and part of which may not be sucked in due to the small negative pressure, and falls between the hollow cylinder 241 and the dust collection hood 24 under the action of gravity, thereby realizing the processing and recovery of sparks in the welding slag.

[0026] When the sliding column 226 provided by the present invention is in use, the electric push rod 224 is turned on, and the output end of the electric push rod 224 drives the connecting plate 222 to move, and the connecting plate 222 drives the welding gun 223 to move through the rotating mechanism, thereby adjusting the height of the welding gun 223, which is convenient for welding anti-theft doors of different heights; during the movement of the connecting plate 222, the connecting plate 222 drives the sliding column 226 to move, and the sliding column 226 slides on the side plate 225, and the side plate 225 limits the sliding column 226 to move in the vertical direction.

[0027] like Figure 4 and Figure 5 As shown, the horizontal plate 227 is provided with a movable opening, and the movable opening is rotatably connected to a connecting column 25 through a rotating shaft 251, and the visual sensor 23 and the dust cover 24 are respectively fixed to the connecting column 25; one end of the rotating shaft 251 is fixed to a third gear 252; both ends of the horizontal plate 227 are fixed to a fixed plate 257, and a bidirectional screw rod 255 is rotatably connected between the two fixed plates 257 through a bearing, and a moving block 254 is symmetrically threaded on the bidirectional screw rod 255; the bottom of the moving block 254 is fixed to a rack, and the rack is respectively engaged with the third gear 252 on the same side; one end of the bidirectional screw rod 255 is provided with a second motor 258; two guide rods 256 are fixed between the two fixed plates 257, and the moving blocks 254 slide on the two guide rods 256.

[0028] When the third gear 252 and rack provided by the present invention are in use, by turning on the second motor 258, the output shaft of the second motor 258 drives the bidirectional screw 255 to rotate, and the two moving blocks 254 are driven to move in different directions through the bidirectional screw 255, and the rack is driven to move in different directions through the moving block 254, and the third gear 252 is driven to rotate in different directions through the rack, and the rotating shaft 251 is driven to rotate in different directions through the third gear 252, and the rotating shaft 251 drives the connected visual sensor 23 and the dust hood 24 to rotate in different directions through the connecting column 25, so that the visual sensor 23 and the dust hood 24 are rotated to align with the gun head of the welding gun 223, the welding seam is monitored by the visual sensor 23, and the welding slag and welding smoke are absorbed by the dust hood 24.

[0029] like Figure 3 As shown, the rotating mechanism includes a vertical plate 228 and a driving motor. Both ends of the welding gun 223 are fixed with a driving rod; one end of the driving rod is rotatably connected to the vertical plate 228 through a bearing; the driving motor is provided at one end of the driving rod.

[0030] The rotating mechanism provided by the present invention is used to adjust the angle of the welding gun 223 when in use. During welding, it is usually necessary to adjust the welding gun 223 to a suitable angle. By turning on the drive motor, the output shaft of the drive motor drives the drive rod to rotate, and the driving rod drives the welding gun 223 to rotate. The welding gun 223 rotates to a suitable angle, which facilitates improving the quality of welding.

[0031] like Figure 2 、 Figure 7 and Figure 8 As shown, two rectangular plates 35 are fixedly connected to the bottom of the workbench 1, and a bidirectional ball screw 33 is rotatably connected between the two rectangular plates 35 through a bearing. Two first limit seats 3 are threadedly connected to the bidirectional ball screw 33, and two cross bars 34 are fixed between the two rectangular plates 35. Both of the two first limit seats 3 are slidably connected to the two cross bars 34; a third motor 36 is provided at one end of the bidirectional ball screw 33; the first limit seat 3 slides through the workbench 1.

[0032] The first limit seat 3 provided by the present invention is used to limit and fix the short side of the anti-theft door when in use. First, the short side of the anti-theft door needs to be installed on the first limit seat 3, and then the third motor 36 is turned on. The third motor 36 drives the bidirectional ball screw 33 to rotate through the output shaft, and drives the two first limit seats 3 to move in different directions through the bidirectional ball screw 33 until the two first limit seats 3 drive the short side of the anti-theft door to be fixed to the long side; during the movement of the first limit seat 3, the first limit seat 3 slides on the cross bar 34, and the cross bar 34 limits the first limit seat 3 to move in the horizontal direction.

[0033] like Figure 7 and Figure 8 As shown, the workbench 1 also slides through two second limit seats 4, and the bottom of the workbench 1 is fixedly connected to two mounting plates 45; the mounting plates 45 are rotatably connected to a reciprocating screw 43 through bearings, and the second limit seat 4 is threadedly connected to the reciprocating screw 43; the bidirectional ball screw 33 is perpendicularly divided into two parts by the reciprocating screw 43; two limit rods 44 are fixedly connected to the mounting plates 45, and the second limit seat 4 is slidably connected to the two limit rods 44; a driving mechanism is provided at one end of the reciprocating screw 43.

[0034] The second limiting seat 4 provided by the present invention is used to limit and fix the short side of the anti-theft door when in use. First, the long side of the anti-theft door needs to be installed on the second limiting seat 4. During the rotation process, the bidirectional ball screw 33 drives the reciprocating screw 43 to rotate through the driving mechanism, and the reciprocating screw 43 drives the second limiting seat 4 to move, and the long side and short side of the anti-theft door are driven to cooperate and fix through the second limiting seat 4; during the movement of the second limiting seat 4, the second limiting seat 4 slides on the limiting rod 44, and the limiting rod 44 limits the second limiting seat 4 to move in the horizontal direction. like Figure 8 As shown, the driving mechanism includes a fixed box 5 fixed to the bottom of the workbench 1; one end of the two reciprocating screws 43 is symmetrically fixed with a second bevel gear 46; one end of the limit rod 44 is fixed to the fixed box 5; the bidirectional ball screw 33 is fixed with a first bevel gear 37; the first bevel gear 37 is engaged with the two second bevel gears 46; the reciprocating screw 43 and the bidirectional ball screw 33 are both rotatably connected to the fixed box 5 through bearings; the limit rod 44 and the cross bar 34 are both fixed to the fixed box 5.

[0035] The driving mechanism provided by the present invention is used to link the bidirectional ball screw 33 and the reciprocating screw 43 when in use. During the rotation of the bidirectional ball screw 33, the bidirectional ball screw 33 drives the first limit seat 3 to move; at the same time, the bidirectional ball screw 33 drives the first bevel gear 37 to rotate, and drives the second bevel gear 46 to rotate through the first bevel gear 37. Since the two second bevel gears 46 are symmetrically arranged on both sides of the first bevel gear 37, the two second bevel gears 46 rotate synchronously in opposite directions, and the reciprocating screw 43 is driven to rotate through the second bevel gear 46, and the second limit seat 4 is driven to move through the reciprocating screw 43.

[0036] like Figure 7 As shown, the first limiting seat 3 is fixedly connected to a first placing plate 31; the first placing plate 31 is provided with a first lower pressure plate 32; the first limiting seat 3 is fixedly connected to a first cylinder; the output end of the first cylinder is fixedly connected to the top of the first lower pressure plate 32; the first lower pressure plate 32 is slidably connected to the first limiting seat 3.

[0037] When the first placement plate 31 and the first lower pressure plate 32 provided by the present invention are in use, the short side of the anti-theft door is placed on the first placement plate 31. Through the movement of the driving mechanism, the short side and the long side of the anti-theft door are coordinated. By opening the first cylinder, the output end of the first cylinder drives the first lower pressure plate 32 to move downward until the short side of the anti-theft door is pressed tightly.

[0038] like Figure 7 As shown, the second limiting seat 4 is fixedly connected to a second placing plate 41; the second placing plate 41 is provided with a second lower pressure plate 42; the second limiting seat 4 is fixedly connected to a second cylinder; the output end of the second cylinder is fixedly connected to the top of the second lower pressure plate 42; the second lower pressure plate 42 is slidably connected to the second limiting seat 4.

[0039] When in use, the second placement plate 41 and the second lower pressure plate 42 provided by the present invention place the long side of the anti-theft door on the first placement plate 31. Through the movement of the driving mechanism, the long side and the short side of the anti-theft door cooperate with each other. By opening the second cylinder, the output end of the second cylinder drives the second lower pressure plate 42 to move downward until the long side of the anti-theft door is pressed tightly.

[0040] like Figure 6 As shown, a connecting pipe is fixedly connected to the top of the dust hood 24 , and the connecting pipe extends inside the hollow cylinder 241 . An electric air valve 242 is installed on the connecting pipe; the electric air valve 242 is electrically connected to the first motor 247 .

[0041] The electric air valve 242 provided by the present invention is used for sealing and circulating the connecting pipe when in use. When the first motor 247 is turned on, the electric air valve 242 is open to facilitate the absorption of welding smoke and welding slag. When the next welding position is to be changed or a lot of welding slag is accumulated between the hollow cylinder 241 and the dust hood 24, the second motor 258 is turned off and the electric air valve 242 is closed at the same time. At this time, a closed space is formed between the dust hood 24 and the hollow cylinder 241, and then the fan 262 removes the welding slag in the hollow cylinder 241 through the dust suction pipe 26.

[0042] Working principle: When welding security doors, the steel components of the security doors need to be fixed first, and then metal cutting and welding equipment are used to manufacture them. Welding slag will be generated during the welding process. If the welding is not cleaned in time, the slag splashing will not only lead to a bad welding environment, but also the slag splashing to the connection of the transmission components, thereby causing the security door to be unstable and reducing the welding quality.

[0043] When the processing mechanism provided by the present invention is in use, it monitors the route of the welding gap of the anti-theft door through the visual sensor 23, and then transmits the route data to the computer system. According to the setting and planning of the route by the computer system, the welding gun 223 is driven to move to a suitable route for welding through the first slide rail 21 and the second slide rail 22. During the welding process, by turning on the fan 262, the fan 262 forms a negative pressure at the entrance of the dust hood 24, and absorbs the welding smoke and welding slag generated by welding through the negative pressure adsorption. The welding smoke and welding slag are sucked into the dust suction pipe 26 through the dust suction hood 24, and finally fall into the collection box 261 from the other end of the dust suction pipe 26. Since some sparks in the welding slag are absorbed before they can be extinguished, if the sparks are not processed The entry of sparks may burn the dust collection pipe 26 and the fan 262, so the first motor 247 needs to be turned on during cleaning. The first motor 247 drives the second gear 246 to rotate through the output shaft, drives the first gear 245 to rotate through the second gear 246, drives the rotating rod 243 to rotate through the first gear 245, and drives the cyclone blades 244 to rotate through the rotating rod 243. The absorbed welding slag is cycloned by the cyclone blades 244, so that the welding is centrifuged on the wall of the hollow cylinder 241, part of which will be sucked into the collection box 261, and part of which may not be sucked in due to the small negative pressure, and falls between the hollow cylinder 241 and the dust collection hood 24 under the action of gravity, thereby realizing the processing and recovery of sparks in the welding slag.

[0044] By turning on the second motor 258, the output shaft of the second motor 258 drives the bidirectional screw rod 255 to rotate, and the bidirectional screw rod 255 drives the two moving blocks 254 to move in different directions, and the moving block 254 drives the rack to move in different directions, and the rack drives the third gear 252 to rotate in different directions, and the third gear 252 drives the rotating shaft 251 to rotate in different directions. The rotating shaft 251 drives the connected visual sensor 23 and the dust hood 24 to rotate in different directions through the connecting column 25, so that the visual sensor 23 and the dust hood 24 are rotated to align with the gun head of the welding gun 223, the welding seam is monitored by the visual sensor 23, and the welding slag and welding smoke are absorbed by the dust hood 24.

[0045] The short side of the security door is placed on the first placement plate 31. The movement of the drive mechanism causes the short side of the security door to mate with the long side. The first cylinder is activated, and the output end of the first cylinder drives the first lower pressing plate 32 downward until the short side of the security door is pressed tightly. The long side of the security door is placed on the first placement plate 31. The movement of the drive mechanism causes the long side of the security door to mate with the short side. The second cylinder is activated, and the output end of the second cylinder drives the second lower pressing plate 42 downward until the long side of the security door is pressed tightly. Then, the third motor 36 is turned on. The third motor 36 drives the bidirectional ball screw 33 to rotate via the output shaft, and the bidirectional ball screw 33 drives the two first limiting seats 3 to move in different directions until the two first limiting seats 3 drive the short side of the anti-theft door to be fixed to the long side. During the rotation of the bidirectional ball screw 33, the bidirectional ball screw 33 drives the first bevel gear 37 to rotate, and the first bevel gear 37 drives the second bevel gear 46 to rotate. Since the two second bevel gears 46 are symmetrically arranged on both sides of the first bevel gear 37, the two second bevel gears 46 rotate synchronously in opposite directions, and the reciprocating screw 43 is driven to rotate by the second bevel gear 46, and the reciprocating screw 43 is driven to move by the reciprocating screw 43. The long side of the anti-theft door is fixed to the short side by the second limiting seat 4.
