DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] See also Figure 1-Figure 6 The welding device for electromechanical installation in one embodiment of the present invention comprises a welding gun assembly 1, wherein the welding gun assembly 1 comprises a handle 101 and a welding gun 102, wherein the welding gun 102 is fixedly mounted on the handle 101; a gas guide assembly 2, wherein the gas guide assembly 2 comprises a gas guide cylinder 201, an exhaust shell 202, a hollow cylinder 203, a limiting wall 204, a rotating body 205 and a gas guide pipe 206, wherein the gas guide cylinder 201 is fixedly sleeved on the welding gun 102, and an exhaust shell 202 is also provided at one end of the gas guide cylinder 201, and a plurality of the gas guide cylinders 201 are provided with the gas guide cylinder 201. The hollow cylinder 203 is fixedly arranged at one end of the exhaust shell 202, and a limiting wall 204 is arranged in the hollow cylinder 203, the rotating body 205 is limitedly rotated and assembled in the limiting wall 204, and an air guide pipe 206 is also fixedly arranged in the middle of the rotating body 205; the air supply component 3, the air supply component 3 includes an air intake cylinder 301 and an air intake pipe 302, the air intake cylinder 301 is fixedly arranged at one end of the welding gun 102, one end of the air intake cylinder 301 is connected to the air guide cylinder 201, and the other end of the air intake cylinder 301 is connected to the air intake pipe 302.

[0023] In actual application of this embodiment, when the welding device is used to install electromechanical equipment, the grip 101 is used to hold the welding device, and the air inlet cylinder 301 at one end of the welding gun 102 is connected to the air inlet pipe 302, and the air inlet pipe 302 is used to continuously pump air into the air inlet cylinder 301. During the welding process, when the welding head is started under the control of the electric control switch, the external pump electrically connected to it continuously pumps air into the air inlet cylinder 301 through the air inlet pipe 302, and the air passes through the air inlet cylinder 301. 301 enters the inner cavity of the gas guide cylinder 201 and moves along the gas guide cylinder 201 toward the exhaust shell 202. A plurality of fixed hollow cylinders 203 are arranged on the cavity wall of the exhaust shell 202, and a rotating body 205 is rotatably installed in the middle of the hollow cylinder 203. By adjusting the rotation direction of the rotating body 205 relative to the hollow cylinder 203, the direction in which the gas is ejected along the gas guide pipe 206 can be controlled. During the welding process, the plurality of gas guide pipes 206 are all directed to one side of the welding gun head and are arranged at the welding gun. A conical gas curtain wall is formed between the head and the welding spot, and the initial velocity of the ejected gas is relatively fast at this time, which can blow away the flying chips generated during the welding process, and the flying chips quickly dissipate heat when passing through the gas curtain wall, so that the flying chips will not burn other workers when they are scattered outward, and the formed conical gas curtain wall can also prevent the welding smoke from drifting to the side of the operator. When the operator completes welding, when the welding gun is moved away from the welding spot, several of the rotating bodies 205 rotate in the opposite direction, so that several air guide tubes 206 rotate toward the side away from the welding spot. At this time, the pump continues to output air to the inlet pipe 302 for a period of time. Since several air guide tubes 206 rotate at the same time, the conical gas curtain wall is transformed into an annular gas curtain wall. At this time, the flow rate of the ejected gas is relatively slow, but the cross-sectional area in the circumferential direction is increased, forming a flat gas curtain wall between the operator and the welding spot, which quickly blows away the welding smoke, can effectively prevent the high-temperature welding smoke from being inhaled by the operator, and reduce the probability of respiratory diseases.

[0024] See also Figure 3 In a preferred embodiment of the present invention, the welding gun assembly 1 also includes a trigger 103, a traction rod 104, a pressure block 105 and a contact switch 106. The trigger 103 is elastically slidably arranged in the handle 101, one end of the trigger 103 is fixedly connected to the traction rod 104, the end of the trigger 103 is fixedly provided with a pressure block 105, and the handle 101 is fixedly provided with a contact switch 106.

[0025] In actual application of this embodiment, the trigger 103 is elastically slidably arranged in the grip 101. When the operator pulls the trigger 103, the trigger 103 overcomes the elastic force and moves toward the side of the contact switch 106. When the pressure block 105 and the contact switch 106 are movably abutted, the control circuit starts the welding gun. At the same time, the end of the traction rod 104 pulls the movable disk 402 to move synchronously, so that the rotating bodies 205 linked with the movable disk 402 adjust the rotation direction, thereby changing the directional position of the air guide tube 206.

[0026] See also Figure 2 In a preferred embodiment of the present invention, the exhaust shell 202 is arranged in a conical shape, and a plurality of the hollow cylinders 203 are arranged in a ring array in the circumferential direction.

[0027] In actual application of this embodiment, the exhaust shell 202 adopts a conical structure, so that during the rotation of the rotating body 205, the gas ejected from the air duct 206 will never interfere with the outer shell of the exhaust shell 202, thereby preventing the direction of gas flow from being affected. In addition, a plurality of hollow cylinders 203 are arranged in a circular array in the circumferential direction, so that the air ejected from the plurality of air ducts 206 can form a gas curtain wall connected in sequence in the circumferential direction.

[0028] See also Figure 4 In a preferred embodiment of the present embodiment, the air guide component 2 also includes a nozzle 207 and a fan-shaped nozzle 208, the nozzle 207 is fixedly assembled at the end of the air guide pipe 206, the two groups of fan-shaped nozzles 208 are mirror-arranged on both sides of the nozzle 207, and the two groups of fan-shaped nozzles 208 are rotatably connected to the nozzle 207, and the nozzle 207 and the fan-shaped nozzle 208 are slidably sealed and connected.

[0029] In actual application of this embodiment, the end of the air guide tube 206 is fixedly equipped with a nozzle 207, and both ends of the nozzle 207 are rotatably equipped with fan-shaped nozzles 208. Therefore, when the two sets of fan-shaped nozzles 208 are opening and closing, the guide area of ​​one end of the nozzle 207 changes. When the pressure is constant, according to Bernoulli's principle, the smaller the guide area on one side of the nozzle 207, the faster the movement speed of the fluid, and the larger the guide area on one side of the nozzle 207, the slower the movement speed of the fluid. Therefore, the guide area at one end of the nozzle 207 can be adjusted to change the movement speed of the air. At the same time, the opening angle of the air jet is also adjusted to change its effective area in the circumferential direction, so that the guide area at one end of the nozzle 207 can be matched and adjusted according to the rotation direction of the rotating body 205. By default, during the welding process, several air guide tubes 206 all rotate toward the welding point side, and when the welding is completed, several air guide tubes 206 all rotate toward the side away from the welding point.

[0030] See also Figure 4In a preferred embodiment of the present invention, the air guide component 2 also includes a secondary magnetic body 209 and a main magnetic body 210, and the two groups of secondary magnetic bodies 209 are respectively installed on the two groups of fan-shaped mouths 208, and the main magnetic body 210 is fixedly installed at one end of the limiting wall 204, and the two groups of secondary magnetic bodies 209 are magnetically connected to the main magnetic body 210.

[0031] In actual application of this embodiment, the two fan-shaped nozzles 208 are respectively independently provided with secondary magnetic bodies 209, and the magnetism of the secondary magnetic bodies 209 is matched with the magnetism of the main magnetic body 210. One end of each of the two groups of limiting walls 204 is provided with a main magnetic body 210. When the air guide tube 206 rotates toward one side of the welding point, when the two groups of secondary magnetic bodies 209 are close to the main magnetic body 210 on this side, the two groups of secondary magnetic bodies 209 and the main magnetic body 210 on this side are in a state of opposite poles attracting each other, so that the two groups of fan-shaped nozzles 208 on the nozzle 207 are closed, thereby reducing the diversion area on one side of the nozzle 207. When the air guide tube 206 rotates toward the side away from the welding point, when the two groups of secondary magnetic bodies 209 are close to the main magnetic body 210 on the other side, the two groups of secondary magnetic bodies 209 and the air guide cylinder 201 on the other side are in a state of opposite poles repelling each other, so that the two groups of fan-shaped nozzles 208 on the nozzle 207 are opened, thereby increasing the diversion area on one side of the nozzle 207.

[0032] In one case of this embodiment, the magnetic force between the two sets of secondary magnetic bodies 209 is negligible.

[0033] See also Figure 6 In a preferred embodiment of the present invention, the welding device for electromechanical installation also includes a transmission assembly 4, which includes a fixed plate 401, a moving plate 402, a guide rod 403, a rotating shaft seat 404 and a traction rod 405. The fixed plate 401 is fixedly arranged in the air guide cylinder 201, and a plurality of guide rods 403 are arranged at one end of the moving plate 402. The guide rods 403 are elastically slidably assembled on the fixed plate 401. A plurality of traction rods 405 are also circumferentially arranged on one side of the moving plate 402. One end of the traction rod 405 is rotatably connected to the moving plate 402, and the other end of the traction rod 405 is rotatably connected to the rotating body 205.

[0034] In actual application of this embodiment, when the traction rod 104 pulls the guide rod 403 to move, the guide rod 403 synchronously drives the movable plate 402 to slide on one end of the fixed plate 401. Since one end of the traction rod 405 is rotationally connected to the rotating shaft seat 404, and the other end is rotationally connected to the rotating body 205, several rotating bodies 205 can be pulled to rotate synchronously during the movement, thereby adjusting the jet directions of several air guide tubes 206 at the same time.

[0035] See also Figure 6In a preferred embodiment of the present invention, the transmission assembly 4 also includes a damper 406, which is fixedly arranged in the air cylinder 201, and one end of the damper 406 is fixedly connected to the air cylinder 201, and the movable shaft at the other end of the damper 406 is fixedly connected to the guide rod 403.

[0036] In actual application of this embodiment, a damper 406 is further provided between the gas cylinder 201 and the guide rod 403. When the operator pulls the trigger 103 to the open state, the traction rod 104 pulls the movable plate 402 to slide toward the fixed plate 401 through the guide rod 403, and the elastic member between the fixed plate 401 and the movable plate 402 is in an energy storage state. When the operator releases the trigger 103, the damper 406 can prevent the movable plate 402 from quickly resetting under the elastic force, so that the gas curtain wall can rotate stably, prevent the gas curtain wall from shaking, and prevent welding smoke from penetrating into the other side of the curtain wall.

[0037] The above-mentioned embodiment of the present invention provides a welding device for electromechanical installation. By arranging an air guide cylinder 201 and an exhaust shell 202 on the welding gun 102, the jet direction of several air guide tubes 206 on the exhaust shell 202 can be adjusted according to the welding action, forming a deformable gas curtain wall between the welding gun and the welding point, effectively blocking the splashing of welding slag, and at the same time preventing the welding fume from being inhaled by the operator, thereby improving the operation safety.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
