The top of the workbench 1 is fixed with a support seat 2001, and the top of the support seat 2001 is fixed with a collection box 2002. By setting the collection box 2002, the waste chips can be collected. The supporting seat 2001 and the collecting box 2002 are penetrated by a connecting rod 2003, and the penetration point is slidably connected. The top of the connecting rod 2003 is fixed with a fixed seat 2004, and the top of the fixed seat 2004 is fixed with a brush 2005.

The clamping blocks 1209 are moved away from each other through the connecting rod 1206, so that the clamping blocks 1209 will not clamp the steel pipe, and then the first motor 6 can be started to control the bidirectional threaded rod 8 is reversed, so that the threaded sleeves 9 move away from each other, and the clamping mechanisms 12 move away from each other, and then the threaded sleeves 9 can drive the disc 1205 to contact the fixed column 14. When the disc 1205 continues to move away from the L-shaped support plate 2, the disc 1205 will be squeezed and moved closer to the support block 11. Through the cooperation of the squeezing rod 1207, the inclined block 1208 and the connecting rod 1206, the clamping blocks 1209 can be moved away from each other, and then the steel pipe can be taken out of the rotating sleeve 1201, and the clamping blocks 1209 move away from each other, which makes it convenient to extend the steel pipe into the rotating sleeve 1201 to clamp and fix the steel pipe. When the threaded sleeve 9 moves on the bidirectional threaded rod 8, the protrusion 19 can be driven to move through the L-shaped connecting rod 18.

Through the cooperation of the fixed rod 2010, the square block 2009 and the transmission rod 2008, the baffle 2006 can drive the connecting rod 2003 to move downward, so that the vibration spring 2007 is stretched, and the connecting rod 2003 can drive the fixing seat 2004 and the brush 2005 to move downward. When the protrusion 19 moves between the two groups of arc blocks 2012, the vibration spring 2007 is in a stretched state, so that the connecting rod 2003 drives the brush 2005 to return to its original position upward. Then, when the protrusion 19 moves on the arc block 2012, the brush 2005 can vibrate up and down, and the impurities attached to the brush 2005 can be vibrated off.To prevent a large amount of impurities from being attached to the brush 2005, which will affect the cleaning of the steel pipe connection, the impurities cleaned by the brush 2005 fall into the collection box 2002, which is convenient for the staff to clean up in a centralized manner. A connecting plate 2013 is fixed to the side wall of the collection box 2002, a support rod 2014 is fixed to the outer wall of the connecting rod 2003, and a bearing plate 2015 is fixed to the end of the support rod 2014 away from the connecting rod 2003.

When the connecting rod 2003 moves downward, the fixing seat 2004 can be driven to move downward, so that the U-shaped rod 2020 moves downward, and the supporting rod 2014 drives the push rod 2016 to move downward, so that the push plate 2017 contacts the connecting plate 2013, and then the push plate 2017 is subjected to an extrusion force, so that the push rod 2016 moves upward on the bearing plate 2015, so that the push rod 2016 squeezes the oblique rod 2019, so that the oblique rod 2019 is subjected to an extrusion force, so that the oblique rod 2019 squeezes the U-shaped rod 2020 toward the fixing seat 2 004, so that the U-shaped rod 2020 drives the beating plate 2021 to move, so that the beating plate 2021 beats the brush 2005, and then the cleaning can be further performed, and the dust attached to the brush 2005 can be beaten off. The side wall of the beating plate 2021 is fixed with a beating block 2022. When the beating plate 2021 beats the brush 2005, the beating block 2022 can be inserted into the brush 2005 and the brush 2005, so that the dust attached between the brush 2005 can be cleaned, so that the cleaning effect of the brush 2005 is better.

[0040] Working principle: when it is necessary to weld two groups of steel pipes, the steel pipes can be inserted into the rotating sleeve 1201, and then the first motor 6 can be started to control the bidirectional threaded rod 8 to rotate forward, so that the two groups of threaded sleeves 9 are close to each other, and then the disc 1205 is moved away from the fixed column 14, so that the disc 1205 is not squeezed, and because the reset spring 1204 is in a stretched state, the reset spring 1204 can drive the disc 1205 away from the rotating sleeve 1201, so that the disc 1205 drives the extrusion rod 1207 away from the support block 11, and then the extrusion rod 1207 does not squeeze the inclined block 1208, and because the return spring 1211 is in a stretched state, the connecting rod 1206 can be moved into the rotating sleeve 1201, and the rotating sleeve can be clamped by the clamping block 1209. The steel pipe in 1201 is clamped and fixed, so that the rotating sleeve 1201 can drive the steel pipe to move, and then when the rotating sleeve 1201 drives the welding parts of the two groups of steel pipes to fit together, the outer wall of the welding part of the steel pipe can fit with the brush 2005. When the second motor 15 is started, the rotating rod 16 can be rotated, and the large gear 1210 can be driven to rotate through the small gear 17, so that the large gear 1210 drives the rotating sleeve 1201 and the steel pipe to rotate, and then the welding part of the steel pipe rotates on the brush 2005, and then the welding part of the steel pipe can be cleaned by the brush 2005, and the impurities at the welding part of the steel pipe can be brushed off to prevent a large amount of impurities from being attached to the welding part of the steel pipe, which will affect the welding of the steel pipe. When the cylinder 3 is started, the welding part When the machine 4 moves downward for welding, the steel pipe is rotated to facilitate the welding operation of the steel pipe. When the welding is completed, one group of discs 1205 can be pushed to make the disc 1205 approach the support block 11, and the clamping blocks 1209 are moved away from each other by squeezing the rod 1207, the inclined block 1208 and the connecting rod 1206, so that the clamping blocks 1209 do not clamp the steel pipe, and then the first motor 6 can be started to control the reversal of the bidirectional threaded rod 8 to make the threaded sleeves 9 move away from each other, and the clamping mechanism 12 move away from each other, and then the threaded sleeve 9 can drive the disc 1205 to contact the fixed column 14. When the disc 1205 continues to move away from the L-shaped support plate 2, the disc 1205 will be squeezed and moved closer to the support block 11. By the cooperation of the extrusion rod 1207, the inclined block 1208 and the connecting rod 1206, the clamping blocks 1209 can be moved away from each other, so that the steel pipe can be taken out of the rotating sleeve 1201, and the clamping blocks 1209 can be moved away from each other, so that it is convenient to insert the steel pipe into the rotating sleeve 1201 to clamp and fix the steel pipe. When the threaded sleeve 9 moves on the two-way threaded rod 8, the protrusion 19 can be driven to move by the L-shaped connecting rod 18. When the protrusion 19 moves to contact with the arc block 2012, the arc block 2012 will be squeezed and moved downward. By the cooperation of the fixed rod 2010, the square block 2009 and the transmission rod 2008, the baffle 2006 can drive the connecting rod 2003 to move downward, so that the vibration spring 2007 is stretched.The connecting rod 2003 can drive the fixing seat 2004 and the brush 2005 to move downward. When the protrusion 19 moves between the two sets of arc blocks 2012, the vibration spring 2007 is in a stretched state, so that the connecting rod 2003 drives the brush 2005 to return to its original position upward. Then, when the protrusion 19 moves on the arc block 2012, the brush 2005 can vibrate up and down, and the impurities attached to the brush 2005 can be vibrated off, so as to prevent a large amount of impurities from being attached to the brush 2005, which will affect the cleaning of the steel pipe connection.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
