[0002] MIG welding is a commonly used welding method. In the welding process, an inert gas is used as a shielding gas. The amount of gas added during use will cause different effects on the final weld scar. Therefore, if the same welding effect is to be achieved, it is necessary to adjust the gas amount in the internal space in real time to keep it within a perfect use range, so as to ensure the welding quality. There are also some devices for adjusting the gas volume in the prior art, but these devices can only adjust the size of the discharged gas volume during adjustment, lacking the application and adjustment of the gas volume after discharge.

Detailed Description of the Invention

[0022] The present invention will be further described below in conjunction with specific embodiments. Here, the present invention is explained by means of schematic embodiments and descriptions of the present invention, but it is not intended to limit the present invention.

[0023] Embodiment: As Figures 1-7A real-time gas regulation device for titanium alloy MIG welding as shown includes a main body housing 101. On one side of the main body housing 101, there is a data display table 104 and a scale mark 103. On the surface opposite to the data display table 104, there is an opening and closing door 105. The inside of the main body housing 101 is divided into two spaces. The space closer to the data display table 104 is the first space, and the space closer to the opening and closing door 105 is the second space. The main body housing 101 can be set as a transparent housing on one side or both sides according to the situation, which is convenient for knowing the internal situation or installing a camera.

[0024] In the first space, there is an inert gas cylinder 110. A main gas outlet pipe 112 is connected to the inert gas cylinder 110. The end of the main gas outlet pipe 112 is connected to a gas storage cylinder 120. A terminal gas pipe 108 is connected to the main gas outlet pipe 112 and extends into the second space.

[0025] Taking the gas outlet regulating shell 117 as a node, the main gas outlet pipe 112 is divided into two sections on the left and right. One section connects the gas outlet regulating shell 117 and the inert gas cylinder 110. This section is also provided with a gas outlet check valve 115 and a manual gas outlet valve 114, which are used to supply the gas in the inert gas cylinder 110 for the terminal gas pipe 108 to use. The other section connects the gas outlet regulating shell 117 and the gas storage cylinder 120. This section is also respectively provided with a recycling check gas supply valve 119 and a recycling manual valve 118, which are used to supply the gas recycled by the gas storage cylinder 120 for the terminal gas pipe 108 to use.

[0026] At the bottom of the second space, there is an air extraction port 106. The air extraction port 106 is arranged on an air extraction device 109. The air extraction device 109 is fixedly installed on the main body housing 101. A gas monitoring table 107 is also provided on the air extraction device 109. A recycling gas pipe 125 is connected to the air extraction port 106. The recycling gas pipe 125 is connected to a filtering device 126. The filtering device 126 is connected to the gas storage cylinder 120. A recycling terminal pipe 131 is connected to the gas storage cylinder 120 and is communicated with the inert gas cylinder 110.

[0027] A regulating plate 102 is slidably installed on the main body housing 101. On one side of the regulating plate 102, a pointer is fixedly installed. On the other side, an upper end clamping column 140 and a lower end clamping column 141 are fixedly installed. The upper end clamping column 140 is used to drive the gas outlet regulating component to rotate, and the lower end clamping column 141 is used to drive the recycling regulating component to rotate.

[0028] The air outlet adjustment component includes an air outlet screw rod 137, which is fixedly connected to the main air outlet gear 138. The main air outlet gear 138 is rotatably installed on the main body housing 101. The main air outlet gear 138 meshes with the secondary air outlet gear 139. The secondary air outlet gear 139 is rotatably installed on the main body housing 101. The secondary air outlet gear 139 cooperates with the air outlet adjustment inner valve 116 in the air outlet adjustment valve. There is a hexagonal groove on the secondary air outlet gear 139, and there is a hexagonal switch head on the air outlet adjustment inner valve 116 to drive the rotation of the air outlet adjustment inner valve 116. The air outlet adjustment valve further includes an air outlet adjustment housing 117, which is arranged on the main air outlet pipe 112, and the upper end clamping column 140 is in threaded cooperation with the air outlet screw rod 137.

[0029] The recovery adjustment component includes a recovery screw rod 136, which is fixedly connected to the recovery gear 135. The recovery gear 135 is rotatably installed on the main body housing 101. The recovery gear 135 meshes with the main gear 134. The main gear 134 is fixedly connected to the output shaft of the encoder-driven motor 133. The encoder-driven motor 133 is fixedly installed on the main body housing 101. The recovery gear 135 cooperates with the recovery adjustment inner valve 121 in the recovery adjustment valve to drive the rotation of the recovery adjustment inner valve 121. The recovery adjustment valve further includes a recovery adjustment housing 122, which is arranged on the gas storage cylinder 120, and the lower end clamping column 141 is in threaded cooperation with the recovery screw rod 136.

[0030] A recovery one-way valve 123 and a recovery pressure gauge 124 are successively connected to the recovery gas pipe 125.

[0031] A recovery transport one-way valve 129 and a recovery transport pressure gauge 130 are further arranged between the filtering device 126 and the gas storage cylinder 120. A filtering one-way valve 127 is also arranged on the side of the filtering device 126 and is connected to the filtering exhaust port 128, and the filtering exhaust port 128 is communicated with the outside air.

[0032] A recovery terminal one-way valve 132 is arranged on the recovery terminal pipe 131 for introducing the gas in the gas storage cylinder 120 into the inert gas cylinder 110.

[0033] The working principle of the present invention: Open the opening and closing door 105 of the present invention, connect the inert gas pipe of the welding torch to the terminal gas pipe 108 in advance, place the object to be welded in the main body housing 101, and then close the opening and closing door 105. The welding program adopts automatic welding.

[0034] The pointer of the adjusting plate 102 is initially at the bottom. At this time, the gas outlet adjusting valve composed of the gas outlet adjusting inner valve 116 and the gas outlet adjusting housing 117 is in the closed state, and the recovery adjusting valve composed of the recovery adjusting inner valve 121 and the recovery adjusting housing 122 is in the open state. During welding, the gas monitoring meter 107 monitors the amount of inert gas in the second space. When the gas volume is insufficient, a signal is sent to the encoder-driven motor 133. The encoder-driven motor 133 drives the main gear 134 to rotate, and the main gear 134 drives the recovery gear 135 and the recovery screw rod 136 to rotate, thereby causing the adjusting plate 102 to rise. The rise of the adjusting plate 102 will drive the gas outlet screw rod 137 and the main gas outlet gear 138 to rotate. The main gas outlet gear 138 meshes with the secondary gas outlet gear 139, driving the secondary gas outlet gear 139 to rotate. The secondary gas outlet gear 139 drives the gas outlet adjusting inner valve 116 to rotate, opening the gas outlet adjusting valve and closing the recovery adjusting valve. The gas enters the terminal gas pipe 108 from the inert gas cylinder 110 for use by the welding torch.

[0035] When the gas monitoring meter 107 monitors that the amount of gas inside reaches the perfect state range for welding, the welding torch starts to work. When the continuously input welding protection gas amount exceeds the perfect range, adjustment and reduction are required. The recovery adjusting valve composed of the recovery adjusting inner valve 121 and the recovery adjusting housing 122 opens, and the gas outlet adjusting valve closes.

[0036] The main principle is that the encoder-driven motor 133 drives the main gear 134 to reverse, thereby driving the adjusting plate 102 to descend under the action of the recovery gear 135, which can be achieved. At this time, the air extraction device 109 starts to work, sucking the gas in the second space from the air extraction port 106 into the recovery adjusting housing 122, the recovery check valve 123, and the recovery gas pipe 125, and finally reaching the filtering device 126. After being filtered by the filtering device 126, it enters the gas storage cylinder 120 through the recovery transport check valve 129, and the remaining gas is discharged through the filtering check valve 127.

[0037] Part of the gas reaching the gas storage cylinder 120 is directly recycled into the inert gas cylinder 110 through the recovery terminal pipe 131 and the recovery terminal check valve 132, and the other part enters the recovery one-way supply valve 119 and the recovery manual valve 118 for use in supplying the terminal gas pipe 108. The recovery manual valve 118 can manually control the gas flow rate entering the terminal gas pipe 108.

[0038] The gas outlet monitoring meter 113, the recovery pressure gauge 124, and the recovery transport pressure gauge 130 are used to monitor the gas volume in each pipeline to ensure safe use.

[0039] Matters not described in this invention are applicable to the prior art.
