Description

Technical Field

[0002] Carbon dioxide shielded welding is a commonly used arc welding method that uses carbon dioxide gas to protect the weld of the molten metal during the welding process; carbon dioxide gas can form a stable protective atmosphere during arc welding, preventing oxygen and other impurities from entering the welding area to reduce oxidation, pores and the generation of harmful inclusions.

[0003] In the related art, it is proposed that a large amount of spatter will be generated during carbon dioxide shielded welding accompanied by continuous operation, so that the welding gun shield nozzle is blocked by welding slag, thereby affecting the transportation of carbon dioxide and the use of welding wire. For example, the patent with the prior art publication number CN114211096A provides a carbon dioxide shielded welding machine, which is provided with a driving component and a scraping component on the shield nozzle. The driving component is rotated by external force to drive the scraping component to rotate, and then the scraping component scrapes and cleans the welding slag in the shield nozzle.

[0004] Although the above-mentioned prior art solution can achieve the effect of scraping and cleaning the welding slag in the protective mouth through the setting of the driving component and the scraping component, smoke will be generated at the welding position during welding, affecting the workers' vision and causing reduced quality of the weldment.

[0039] The present application is further described in detail below in conjunction with the accompanying drawings.

[0040] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses a carbon dioxide shielded welding machine, including a welding gun 1;

[0041] The clamping and placing mechanism 2 is arranged at the top of the welding gun 1, and the clamping and placing mechanism 2 is used to retract and fix the suction mechanism 5 when it is not in use;

By setting the clamping mechanism 3, the filter channel 4 and the suction mechanism 5 can be fixed during welding so that they will not shake at will. The welding gun 1 needs to be moved frequently during welding, so the use of the clamping mechanism 3 can prevent the filter channel 4 and the suction mechanism 5 from changing the current working state.

[0046] Reference Figure 1 and 4 The clamping mechanism 2 includes a stand 201, and clamping springs 202 are fixedly arranged on both sides of the top of the stand 201.

The stand 201 is fixedly arranged on the top of the welding gun 1.

[0047] When in use, directly pick up the filter channel 4 so that the first ventilation pipe 4011 leaves the anti-skid clamping plate 203 in the clamping mechanism 2. The anti-skid grooves provided on the anti-skid clamping plate 203 prevent the first ventilation pipe 4011 from falling off easily. After removing the first ventilation pipe 4011, the anti-skid clamping plate 203 returns to its original position through the elastic force of the clamping spring 202.

[0048] Reference Figure 1 and Figure 2A blocking net 405, a high-efficiency filter layer 406 and an activated carbon filter layer 407 are fixedly arranged on the inner side of the filter channel 4, a first ventilation pipe 4011 is fixedly arranged on one side of the filter channel 4, the first ventilation pipe 4011 is fixedly connected to the second ventilation pipe 401 through a telescopic pipe 402, an air outlet 403 is arranged at the other end of the second ventilation pipe 401, an outer sleeve 404 is fixedly arranged on the outer side of the other end of the first ventilation pipe 4011, a locking claw 4041 is symmetrically fixedly arranged on the outer side of the outer sleeve 404, a hook foot 4042 is arranged at the bottom end of the locking claw 4041, and one side of the bottom end of the hook foot 4042 is arranged as an inclined surface,

[0049] When the generated toxic gas passes through the filter channel 4, it first passes through the blocking net 405 to filter large particles of debris, and then passes through the high-efficiency filter layer or high-efficiency filter layer 406 to filter large particles of dust and some toxic gases, and the activated carbon filter layer 407 filters other toxic gases. The filtered gas is discharged from the air outlet 403 along the first ventilation pipe 4011, the telescopic pipe 402 and the second ventilation pipe 401.

[0050] Reference Figure 2 and Figure 4 The clamping mechanism 3 includes a fixed platform 301, a plurality of tensioning springs 303 are fixedly arranged on the inner side of the fixed platform 301, a cross-carrying plate is fixedly arranged on the other end of the tensioning spring 303, and the cross-carrying plate slide bar 302 is slidably arranged on the inner side, tensioning springs 303 are fixedly arranged on both sides of the fixed platform 301, a snap plate 304 is arranged on the side where the tensioning springs 303 are close to each other, shaft columns are fixedly arranged on both sides of the snap plate 304, a torsion spring 306 is fixedly arranged on the outer side of the shaft column, and the other end of the torsion spring 306 is fixedly arranged on one side of the tensioning spring 303, a limiting plate 305 is arranged on the top of the snap plate 304, and the limiting plate 305 is fixedly arranged on one side of the fixed platform 301, the fixed platform 301 is fixedly arranged on the top of the welding gun 1, and one side of the top of the snap plate 304 is arranged as an inclined surface.

[0051] The outer sleeve 404 is placed on the cross-carrying plate and pressed down. The outer sleeve 404 presses the buckle plate 304 through the locking claw 4041 and the hook foot 4042 set at its bottom end, and the buckle plate 304 will tilt downward. The buckle plate 304 drives the shaft column to rotate, and the shaft column drives the torsion spring 306 to deform. At the same time, the outer sleeve 404 presses the cross-carrying plate and makes the slide bar 302 slide on the inner side of the fixed platform 301, and the tightening spring 303 is compressed until the hook foot 4042 is located at the bottom end of the buckle plate 304, and the outer sleeve 404 is released. The outer sleeve 404 and the cross-carrying plate rise to a certain height through the elastic force of the tightening spring 303, thereby providing a tightening force for the outer sleeve 404, and making the hook foot 4042 contact the bottom end of the buckle plate 304 and buckle it, and the buckle plate 304 can return to its original position through the torsion spring 306, so as to achieve the fixing effect of the outer sleeve 404.

[0053] The motor 502 in the suction mechanism 5 is turned on, so that the driving gear 503 can drive the gear ring 504 to rotate. The rotation of the gear ring 504 drives the suction fan 505 to rotate through the connecting leg 506, and generates suction, so that the toxic gas generated during welding is sucked into the inside of the air inlet channel 501 and transported backward, thereby improving the air quality around the welding pipe user and facilitating the staff to work better.

[0054] In summary, when the carbon dioxide shielded welding machine disclosed in the embodiment of the present application is in use, the filter channel 4 is directly lifted up, so that the first ventilation pipe 4011 leaves the anti-skid splint 203 in the clamping mechanism 2. The anti-skid pattern provided on the anti-skid splint 203 prevents the first ventilation pipe 4011 from falling off easily. After the first ventilation pipe 4011 is removed, the anti-skid splint 203 returns to its original position through the elastic force of the clamping spring 202. The anti-skid splint 203 is slidably arranged on the inner side of the stand 201. Through the arrangement of the telescopic tube 402, the first ventilation pipe 4011 and the second ventilation pipe 401 can be in a horizontal state without affecting the air intake operation. The outer sleeve 404 is pressed against the buckle plate 304 by the locking claw 4041 and the hook foot 4042 arranged at the bottom end thereof, and the buckle plate 304 will tilt downward, and the buckle plate 304 drives the shaft column to rotate, and the shaft column drives the torsion spring 306 to deform. At the same time, the outer sleeve 404 presses the cross-carrying plate and makes the slide bar 302 slide on the inner side of the fixed platform 301, and the tightening spring 303 is compressed until the hook foot 4042 is located at the bottom end of the buckle plate 304, and the outer sleeve 404 is released. The outer sleeve 404 and the cross-carrying plate rise to a certain height through the elastic force of the tightening spring 303, thereby providing a tightening force for the outer sleeve 404 and making the hook foot 4042 The foot 4042 contacts the bottom end of the snap plate 304 and buckles it, and the snap plate 304 can return to its original position through the torsion spring 306, so as to fix the outer sleeve 404. The homeowner's filter channel 4 and the suction mechanism 5 are shaken to change the working state during use. When unlocking, the outer sleeve 404 is pressed downward, and then the snap plate 304 is pressed to lift the outer sleeve 404 so that the hook foot 4042 is out of the buckle state with the snap plate 304, and then the motor 502 in the suction mechanism 5 is turned on, so that the driving gear 503 can drive the gear ring 504 to rotate, and the rotation of the gear ring 504 drives the suction fan 5 through the connecting leg 506. 05 rotates and generates suction, sucking the toxic gas generated during welding into the interior of the air inlet channel 501 and transporting it inward. When passing through the interior of the filter channel 4, it first passes through the blocking net 405 to filter large particles of debris, and then passes through the high-efficiency filter layer or high-efficiency filter layer 406 to filter large particles of dust and some toxic gases, and the activated carbon filter layer 407 filters other toxic gases.
