[0003] In this regard, China applied for patent number: CN117415556B, which discloses a positioning device for welding of green building steel structures. The technical problem to be solved is: in the process of positioning the steel structure by the existing steel structure welding equipment, due to the loose fixation, the steel structure is dislocated or falls off during the welding process, which greatly affects the production efficiency and production accuracy. At the same time, there are a lot of burrs and debris during cutting, which leads to inaccurate positioning and uneven welding of the positioning device. The technical solution is: a positioning device for welding green building steel structures, including a workbench and an annular telescopic rod, etc.; the workbench is provided with an annular telescopic rod for transmitting and positioning hollow circular tubes. The present invention realizes that through the annular groove set on the lower side of the annular telescopic rod, the annular telescopic rod is pushed by the electric push rod, and the annular telescopic rod drives the slider to fit the annular groove to move, so that the annular telescopic rod moves in an arc shape to achieve the transmission positioning of the hollow circular tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The positioning device for welding green building steel structure comprises a first positioning seat, an operating table, a second positioning seat, a side block, a first motor, a first gear, a first rotating frame, a second gear, a second rotating frame, a first positioning clamping plate, a second positioning clamping plate, an auxiliary roller, a sliding groove, a second motor, a screw rod body, a sliding frame, a grinding disc, a limiting ring and an installation bevel gear. When in use, firstly, two groups of steel pipes to be welded are placed on the surfaces of the first positioning seat and the second positioning seat, and then the two groups of steel pipes are aligned with each other and transported. At this time, the first motor is started, and the first gear is driven to rotate by the first motor. Since the first gear is meshed with the second gear, the first gear is meshed with the second gear. The gear and the second gear can respectively drive the first rotating frame and the second rotating frame to rotate. Similarly, the second gear and the second rotating frame will also respectively drive the first positioning clamping plate and the second positioning clamping plate to rotate. At this time, the steel pipe in the middle position can be positioned by rotating the first positioning clamping plate and the second positioning clamping plate. At the same time, the position of the steel pipe can also be limited and clamped through the design of the auxiliary roller, so that the steel pipe is always in an aligned state during subsequent welding. Then, when the welding points of the two groups of steel pipes contact the left and right side surfaces of the grinding disk, the second motor is started at this time, and then the second motor will drive the screw body to rotate. At this time, the sliding frame will reciprocate on the surface of the screw body. The two sets of limit rings are used to limit the moving distance during the movement, so that the grinding disc can always move at the welding place of the two sets of steel pipes. The burrs and impurities at the welding place of the two sets of steel pipes can be ground through the movement of the grinding disc, and the overall grinding effect is good. The welding places of the two sets of steel pipes can be ground at the same time. At the same time, when the screw body rotates, it will drive the installed bevel gear to rotate, and then the installed bevel gear will mesh with the bevel gear column body. At this time, the bevel gear column body will drive the rotating disc to rotate. When the rotating disc rotates, it will drive the convex column to rotate, and then the reciprocating frame will reciprocate back and forth, so that the piston column can be driven to do piston-like movement inside the piston cylinder. Movement can transport the gas to the inside of the gas supply rack, and then the gas can be separated through the design of the partition plate, and then the gas is transported downward from the groove inside the top rack through the gas supply slot, so that the gas can be transported downward along the left and right side surfaces of the grinding disc, and the debris generated by the grinding of the two sets of steel pipe welding parts by the grinding disc can be quickly cleaned. At the same time, when the grinding disc is used to reciprocately grind the welding parts of the two sets of steel pipes, the grinding disc always fits the two sets of steel pipes, so that the debris generated during grinding will not fall into the inside of the steel pipe. Therefore, there is no need to clean the debris inside the steel pipe separately later. The overall cleaning effect is good, which reflects the functionality of the design.

[0019] 2. The positioning device for welding green building steel structure is provided with a rotating ring, a resistance ring, a connecting column, a limiting frame, an impact column, a resistance block and a spring body. When the bevel gear column body is rotating, it can also drive the rotating ring to rotate, and then the rotating ring will drive the resistance ring to rotate clockwise, and then the back of the resistance ring will resist the resistance block, and then the resistance block will be squeezed by the resistance ring and move backward. At this time, the resistance block will drive the impact column to move backward, and the impact column is limited by the limiting frame. When the impact column moves backward, the impact column can resist the front surface of the moving grinding disc, and the impurities on the left and right side surfaces of the grinding disc can be shaken at the moment of resistance to prevent impurities and debris from sticking to the left and right side surfaces of the grinding disc. At the same time, when the resistance ring does not resist the resistance When the friction block is in contact with the spring, the friction block automatically returns to its original position through the design of the spring body and the telescopic tube. Therefore, when the rotating ring drives the friction ring to rotate continuously, it can drive the impact column to continuously contact the front surface of the grinding disc, thereby shaking off the impurities and debris on the outer surface of the grinding disc, thereby enhancing the cleaning effect. When the grinding disc has completed grinding the welding parts of the two groups of steel pipes, the second motor stops moving, and then the operating table can be manually pulled forward from the inside of the first slide groove and the second slide groove, so that the two groups of steel pipes can be butt-welded subsequently. This design can knock the front surface of the grinding disc during welding, so that the debris and impurities accumulated on the outer surface of the grinding disc fall off, thereby avoiding excessive accumulation of debris affecting the grinding and subsequent welding of the steel pipes, which reflects the ingenuity of the design.

The ring 35 rotates clockwise, and then the back side of the resistance ring 35 will resist the resistance block 39, and then the resistance block 39 will be squeezed by the resistance ring 35 and move backward. At this time, the resistance block 39 will drive the impact column 38 to move backward. At this time, the impact column 38 is limited by the limit frame 37.

Due to the meshing between the first gear 7 and the second gear 9, the first gear 7 and the second gear 9 can respectively drive the first rotating frame 8 and the second rotating frame 10 to rotate. Similarly, the second gear 9 and the second rotating frame 10 will also respectively drive the first positioning clamping plate 11 and the second positioning clamping plate 12 to rotate.

[0034] Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device. First, place the two groups of steel pipes to be welded on the surfaces of the first positioning seat 1 and the second positioning seat 4, and then align the two groups of steel pipes with each other for transportation. At this time, start the first motor 6, and drive the first gear 7 to rotate through the first motor 6. Due to the meshing between the first gear 7 and the second gear 9, the first gear 7 and the second gear 9 can respectively drive the first rotating frame 8 and the second rotating frame 10 to rotate. Similarly, the second gear 9 and the second rotating frame 10 will also drive the first positioning clamping plate 11 and the second positioning clamping plate 12 to rotate respectively. At this time, the steel pipe in the middle position can be positioned by rotating the first positioning clamping plate 11 and the second positioning clamping plate 12. At the same time, the position of the steel pipe can also be limited and clamped by the design of the auxiliary roller 13, so that the steel pipe is always in an aligned state during subsequent welding. Then, when the welding points of the two groups of steel pipes contact the left and right side surfaces of the grinding disc 18, start the second motor 15, and then the second motor 15 will drive the screw body 16 to rotate. At this time, the sliding frame 17 will The surface of the screw body 16 moves back and forth, and the moving distance is limited by two sets of limit rings 19 during the movement, so that the grinding disc 18 can always move at the welding place of the two sets of steel pipes. The burrs and impurities at the welding places of the two sets of steel pipes can be ground by the movement of the grinding disc 18, and the welding places of the two sets of steel pipes can be ground at the same time. At the same time, when the screw body 16 rotates, the installed bevel gear 20 is driven to rotate, and then the installed bevel gear 20 is meshed with the bevel gear column body 21. At this time, the bevel gear column body 21 drives the rotating disc 23 to rotate. Rotate, when the rotating disk 23 rotates, the convex column will rotate, and then the reciprocating frame 24 will reciprocate back and forth, thereby driving the piston column 27 to do piston-like movement inside the piston cylinder 28, and can deliver gas to the inside of the gas delivery frame 29, and then the gas can be separated by the design of the partition plate 31, and then the gas is delivered downward from the groove inside the top frame 22 through the gas delivery groove 30, so that the gas can be delivered downward along the left and right side surfaces of the grinding disk 18, and the debris generated by the grinding of the two sets of steel pipe welding parts by the grinding disk 18 can be quickly cleaned;

[0035] When the bevel gear column body 21 is rotating, it can also drive the rotating ring 34 to rotate, and then the rotating ring 34 will drive the contact ring 35 to rotate clockwise, and then the back side of the contact ring 35 will contact the contact block 39, and then the contact block 39 will be squeezed by the contact ring 35 and move backward. At this time, the contact block 39 will drive the impact column 38 to move backward. At this time, the impact column 38 is limited by the limit frame 37. When the impact column 38 moves backward, the impact column 38 can contact the front surface of the moving grinding disk 18, and the impurities on the left and right side surfaces of the grinding disk 18 can be shaken at the moment of contact. At the same time, when the contact ring 35 does not contact When the friction block 39 is touched, the friction block 39 automatically returns to its original position through the design of the spring body 40 and the telescopic cylinder 41. Therefore, when the rotating ring 34 drives the friction ring 35 to rotate continuously, it can drive the impact column 38 to continuously contact the front surface of the grinding disk 18, so that the impurities and debris on the outer surface of the grinding disk 18 can be shaken off. When the grinding disk 18 finishes grinding the welding parts of the two groups of steel pipes, the second motor 15 stops moving, and then the operating table 3 can be manually pulled forward from the inside of the first slide groove and the second slide groove, so that the two groups of steel pipes can be butt-welded later. The above is all the working principles of the present invention.
