The setting of the two movable limit rods in the present invention plays a limiting role on the movable positioning seat, enabling the movable positioning seat to be in a stable state after being connected to the installation frame.

When the output shaft of the servo motor B rotates by a quarter turn, the two rows of welding slot holes come into contact with the two multi-functional hollow frames, and one row of air suction round holes moves to the lower part. At the same time, after the output shaft of the servo motor B rotates by a quarter turn, the negative pressure hose starts to suck air, enabling the welding fumes to enter the circular hollow tube through one row of air suction round holes and then enter the negative pressure hose, avoiding the fumes from affecting the health of the staff. The setting of the two multi-functional hollow frames, on the one hand, plays a sealing role on the two rows of welding slot holes, being beneficial to improving the air suction effect of one row of air suction round holes, and on the other hand, plays a protective role on one row of laser welding heads. Even when a small amount of fumes float out, the fumes will not come into contact with one row of laser welding heads, avoiding the attachment of sundries on the lenses of one row of laser welding heads.

[0026] In the embodiment of the present disclosure, as Figure 9 and Figure 10 shown, the multi-functional mechanism 400 includes: a circular hollow tube 401 and a servo motor B 402; the circular hollow tube 401 is rotatably installed on the mounting frame 101, and a row of welding slots 4011 are respectively opened on the upper and lower sides of the circular hollow tube 401, and a row of air suction round holes 4012 are also opened on the front side of the circular hollow tube 401; the servo motor B 402 is installed on the right side of the mounting frame 101 by screws, and the output shaft of the servo motor B 402 is also fixedly connected to the circular hollow tube 401; the multi-functional mechanism 400 also includes: a negative pressure hose 403 and a multi-functional hollow frame 404; the negative pressure hose 403 is fixedly installed at the left end of the circular hollow tube 401; there are two multi-functional hollow frames 404 in total, and the two multi-functional hollow frames 404 are fixedly installed on the mounting frame 101, and the inner sides of the two multi-functional hollow frames 404 are also in contact with the outer wall of the circular hollow tube 401; Its specific functions are as follows: Since a row of welding slot holes 4011 are respectively formed on the upper and lower sides of the circular hollow tube 401, the laser emitted by a row of laser welding heads 103 can pass through the circular hollow tube 401 normally; also, since the output shaft of the servo motor B402 is fixedly connected to the circular hollow tube 401, and the negative pressure hose 403 is fixedly installed at the left end of the circular hollow tube 401, when the output shaft of the servo motor B402 rotates by a quarter of a turn, the two rows of welding slot holes 4011 come into contact with the two multi-functional hollow frames 404, and a row of air suction round holes 4012 move to the lower side; at the same time, after the output shaft of the servo motor B402 rotates by a quarter of a turn, the negative pressure hose 403 starts to suck air, so that the dust generated during welding can enter the circular hollow tube 401 through a row of air suction round holes 4012, and then enter the negative pressure hose 403, avoiding the smoke from affecting the physical health of the staff; the setting of the two multi-functional hollow frames 404, on the one hand, plays a sealing role for the two rows of welding slot holes 4011, which is beneficial to improving the air suction effect of a row of air suction round holes 4012, and on the other hand, plays a protective role for a row of laser welding heads 103. Even when a small amount of dust floats out, the dust will not come into contact with a row of laser welding heads 103, avoiding debris adhering to the lenses of a row of laser welding heads 103.

[0027] The specific usage mode and functions of this embodiment are as follows: When the present invention is in use, first, the staff installs the installation frame 101 on the workbench through bolts, and then installs a corresponding plurality of assembly tooling on the movable positioning seat 301 through screws; then, through an external robot, the accessories are placed on the plurality of assembly tooling. When welding and assembling are required, the servo motor A 104 is started. When the output shaft of the servo motor A 104 rotates, a row of movable mounting blocks 102 can drive a row of laser welding heads 103 to move simultaneously, realizing the automatic welding and assembly of multiple groups of metal pipe fittings; when the output shaft of the servo motor A 104 rotates in the reverse direction, a row of movable mounting blocks 102 can also drive a row of laser welding heads 103 to move simultaneously, also realizing the automatic welding and assembly of multiple groups of metal pipe fittings; after the assembly is completed, the output shaft of the servo motor B 402 rotates one-quarter of a circle. At this time, the two rows of welding slot holes 4011 are in contact with the two multifunctional hollow frames 404, and a row of air suction round holes 4012 moves to the lower part; at the same time, after the output shaft of the servo motor B 402 rotates one-quarter of a circle, the negative pressure hose 403 starts to suck air, so that the soot generated during welding can enter the circular hollow pipe 401 through a row of air suction round holes 4012, and then enter the negative pressure hose 403, avoiding the influence of the fumes on the physical health of the staff; the setting of the two multifunctional hollow frames 404, on the one hand, plays a sealing role for the two rows of welding slot holes 4011, which is beneficial to improving the air suction effect of a row of air suction round holes 4012, and on the other hand, plays a protective role for a row of laser welding heads 103. Even when a small amount of soot floats out, the soot will not contact a row of laser welding heads 103, avoiding the attachment of sundries on the lenses of a row of laser welding heads 103; When the assembly tooling needs to be replaced, the staff pulls out the movable positioning seat 301. When the staff pulls or pushes the movable positioning seat 301, the movable positioning seat 301 can drive the two movable limit rods 203 to move upward, so that the two movable limit rods 203 are automatically separated from the two limit card slots 3012, facilitating the installation and disassembly of the movable positioning seat 301 and making the replacement of the tooling on the movable positioning seat 301 more convenient. Then, the corresponding assembly tooling is installed on the movable positioning seat 301 through screws. The settings of the rectangular detection seat 302 and the rectangular detection block 305 have an auxiliary pressing effect on the external robot, making the external robot more stable during use. When the external robot is slightly skewed after long-term use, under the action of friction, when the rectangular detection block 305 is pulled out, the two front-side spiral springs B307 are compressed, and when the rectangular detection block 305 is inserted, the two rear-side spiral springs B307 are compressed. When the two front-side spiral springs B307 are compressed, the inclined mounting frame 303 can automatically press the rear-side switch 310. When the two rear-side spiral springs B307 are compressed, the inclined mounting frame 303 can automatically press the front-side switch 310. When one of the switches 310 is pressed, the alarm 309 works, facilitating the reminder to the staff to timely detect whether there is any looseness in the external robot and being beneficial to improving the placement and extraction accuracy of subsequent accessories.
