[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the beam steel is transported to the top of the transfer plate via a transmission component at a certain point, and the steel component is positioned and transported by the second transmission component to the limit flip push component for fixing, and then after being flipped 90 degrees clockwise, the steel component is flipped and rotated to a vertical state. At this time, the lower surface of the steel component is horizontally fitted with the upper surface of the beam steel, and then the steel component is horizontally pushed by the limit flip push component to translate it, and it is moved to the welding position, fixed point welding, and then the connection part of the beam steel and the steel component is welded by uniform welding after the rotary welding component rotates one circle.

[0018] 2. The beam steel is placed on the transmission component 1 for positioning and conveying, and arrives at the inner cavity of the processing room with the transmission of the supporting roller. The driving member starts to slide through the rotation of the screw rod 2. The two driving members simultaneously drive the inclined block to slide toward the middle of the inclined table, and the driving member passes through the groove to ensure the smooth sliding of the inclined block. Since the slope surface of the inclined table abuts against the inclined block, the elastic member 2 begins to compress at this time, and the pressure plate slides toward the middle direction on the surface of the transfer plate. The height of the pressure plate during sliding rises and is higher than the upper surface height of the supporting roller. The beam steel is clamped and fixed by the pressure plates on both sides of the end to ensure its welding stability with the steel structure.

[0019] 3. In order to adapt to the welding of beams of different widths, the distance between the two frame plates is adjusted. First, the servo motor drives the worm to rotate, and the shaft on the worm wheel rotates together, pushing the cam 2 to the initial cam 1 position. At this time, the longitudinal wheel contacts the surface of the conveyor belt 1 and is used for the longitudinal sliding of the frame plate. After adjusting the distance between the two frame plates, the servo motor continues to rotate to restore the cam 1 to the initial height. At this time, the transverse wheel contacts the surface of the conveyor belt 1, reducing the friction between the frame plate and the conveyor belt 1, and realizing the use of two functions;

[0020] 4. After the steel component is flipped and pushed to the welding position of the beam steel, the electric push rod pushes the upper plate and the hollow plate frame downward synchronously. After the broken groove passes through the outside of the electric clamp, the driven gear rotates evenly around the main gear. In this process, the welding gun welds the connection between the steel component and the beam steel to realize the welding work of the beam steel and the steel component. Fixed-point automatic welding is highly efficient. BRIEF DESCRIPTION OF THE DRAWINGS

In use, the distance of the adjusting component is changed according to the width of the beam steel so that the beam steel can be moved through the transmission component 1. The transport component 1 is positioned and transported to the clamping and rotating lifting component for clamping and fixing. In this process, the end of the beam steel contacts the inner wall surface of the processing chamber 2. The steel component is then positioned and transported by the transport component 2 to the limit flipping and pushing component for fixing. After that, it is flipped 90 degrees clockwise and rotated to a vertical state. At this time, the lower surface of the steel component is horizontally fitted with the upper surface of the beam steel. After that, the steel component is horizontally pushed by the limit flipping and pushing component to translate the steel component and move it to the welding position for fixed-point welding. After that, the rotary welding component is rotated one circle for uniform welding, and the connection between the beam steel and the steel component is welded. Since the beam steel and the steel component are in a clamped state during welding, the accuracy of the welding point is improved, thereby improving the welding quality.

[0034] See also Figure 6As shown, the clamping rotation lifting assembly includes a transfer plate 17 arranged on the notch on the top surface of the base 1, a plurality of supporting rollers 18 are installed on the top surface of the transfer plate 17, and two tilting platforms 11 are arranged inside the transfer plate 17, and a driving motor is installed on the supporting roller 18 in the middle position, and an inclined block 35 is abutted on the inclined surface of each tilting platform 11, and a driving member 34 of a T-shaped structure is elastically installed at the bottom of the inclined block 35, and a pressing plate 19 for sliding on the upper limit of the top surface of the transfer plate 17 is installed on the top surface of the inclined block 35, and the pressing plate 19 is arranged at the end of the transfer plate 17, and the insertion end of the driving member 34 extends to the inside of the inclined block 35 and is sleeved with an elastic member 2 36, and a through groove 24 for the driving member 34 to pass horizontally is provided on the inclined surface of each tilting platform 11, and a screw rod 2 driven by a dual-axis motor is installed below the tilting platform 11. 33, the outer surface of the screw rod 33 is threadedly connected with the driving member 34, the beam steel is first transported by the transmission component 1 and reaches the inner cavity of the processing chamber 2 with the transmission of the supporting roller 18. When the end of the beam steel fits the inner wall surface of the processing chamber 2, the driving member 34 starts to slide through the rotation of the screw rod 33. At this time, the two driving members 34 simultaneously drive the inclined block 35 to slide toward the middle of the tilting table 11, and the driving member 34 passes through the through groove 24 to ensure the smooth sliding of the inclined block 35. Due to the contact between the slope surface of the tilting table 11 and the inclined block 35, the elastic member 2 36 begins to compress at this time. After the pressure plate 19 slides on the surface of the transfer plate 17, the height rises and is higher than the upper surface height of the supporting roller 18. The beam steel is clamped and fixed by the pressure plates 19 on both sides of the end to ensure its welding stability with the steel structure.

[0035] See also Figure 6 As shown, the clamping rotating lifting assembly also includes a bracket seat arranged below the notch of the transfer plate 17, a rotating cylinder 26 is installed on the upper surface of the bracket seat, a hydraulic cylinder 25 is installed on the driving end of the rotating cylinder 26, and the pushing end of the hydraulic cylinder 25 is fixed to the bottom surface of the transfer plate 17; a conveyor belt 2 for conveying the welded beam steel is arranged at the rear side of the bottom of the base 1, and the upper surface of the conveyor belt 2 is flush with the height of the top outer surface of the supporting roller 18;

[0036] When welding is completed, the hydraulic cylinder 25 pushes the transfer plate 17 downward, and then the rotary cylinder 26 rotates 90 degrees, so that the upper surface of the supporting roller 18 is flush and parallel to the height of the conveyor belt 2. The welded workpiece is transferred to the conveyor belt 2 for transportation by driving the supporting roller 18 in the middle position.

[0037] See also Figure 7As shown, the limit flip push assembly includes a rotating plate 27 rotatably arranged on the top boss of the base 1, a bonding plate 28 is fixed on the upper surface of the rotating plate 27, and an electric push rod 29 and an electric push rod 31 are respectively arranged inside the bonding plate 28. The push end of the electric push rod 29 is fixedly connected to an electric clamp 30 for clamping the steel member, and the push end of the electric push rod 31 is fixedly connected to a stopper 32 for limiting the end of the steel member. In the initial state, the stopper 32 is exposed on the upper surface of the bonding plate 28, and the steel member passes through the positioning of the transmission assembly 2. After being transported, it passes through the middle of the electric clamp 30 and is blocked by the end of the steel component by the block 32. Then the electric clamp 30 clamps the steel component, the electric push rod 31 is powered off and pushes the block 32 to slide into the interior of the bonding plate 28, and then the rotating plate 27 is turned 90 degrees clockwise to change the steel component from a horizontal state to a vertical state. At this time, the bottom surface of the steel component is in contact with the upper surface of the beam steel, and then the electric push rod 29 is extended and pushes the electric clamp 30 and the steel component to slide to the welding position, which is convenient for subsequent fixed-point welding.

[0038] See also Figure 1 and Figure 2 As shown, the transmission component 1 includes a U-shaped carrier frame 3, a conveyor belt 1 4 is installed inside the carrier frame 3, and limit rods 5 are arranged at both ends of the carrier frame 3 and on one side adjacent to the conveyor belt 1 4, and two frame plates 6 that slide with the limit rods 5 are sleeved on the outer surface of the conveyor belt 1 4;

[0039] The adjustment assembly includes a screw rod 1 which is rotatably mounted on the carrier 3 and is used to drive the two frame plates 6 to move simultaneously in opposite directions. The adjustment seats at the top of the two frame plates 6 are threadedly connected to the screw rod 1. During use, the frame plates 6 on both sides are driven to move simultaneously toward the middle of the conveyor belt 4 by turning the screw rod 1, thereby changing the distance between the two frame plates 6, thereby adapting to the conveying and welding work of beams of different widths.

[0040] See also Figure 3 , Figure 4 and Figure 5 As shown, a plurality of auxiliary wheels 7 for assisting the transmission of the beam steel are rotatably installed on the inner side surface of the frame plate 6, and the auxiliary wheels 7 are in contact with the side surface of the beam steel to assist the transportation of the beam steel. A worm 9 is rotatably installed inside the frame plate 6, and a worm wheel 10 is meshed at the lower end of the worm 9, and a servo motor 8 is installed at the end of the worm 9 and extends to the outer surface of the frame plate 6. A plurality of cams 12 and cams 2 13 are respectively fixedly sleeved on the outer surface of the shaft rod fixedly connected in the middle of the worm wheel 10, and the cams 12 and cams 2 13 are arranged at intervals, and the cams 2 13 coincide with the position of the cams 12 after rotating 90 degrees, and the bottom of the cams 12 abuts against the transverse wheels 14 that are in rolling contact with the conveyor belt 1 4, and the bottom of the cams 2 13 abuts against the longitudinal wheels 15;

[0041] The inner wall surface of the frame plate 6 is provided with a plurality of track grooves, and the surface of the support connected with the transverse wheel 14 and the longitudinal wheel 15 is provided with a slider that slides with the track groove, and an elastic member 16 is installed between the slider and the track groove. When the transverse wheel 14 and the longitudinal wheel 15 are respectively subjected to the extrusion external force of the cam 12 and the cam 2 13, the elastic member 16 will be elastically stretched, and the elastic member 16 will be elastically reset after the external force disappears;

[0042] The frame plate 6 is sleeved on the outside of the conveyor belt 4. Since the frame plate 6 is fixed to the adjustment seat, the frame plate 6 is driven to move through the adjustment seat. When adjusting the distance between the two frame plates 6, the servo motor 8 first drives the worm 9 to rotate 90 degrees. Due to the helical shape of the worm 9, it meshes with the tooth surface of the worm wheel 10 to produce a transmission effect, thereby driving the worm wheel 10 to rotate. Due to the helical shape of the tooth surface of the worm wheel 10, the worm 9 cannot be reversely transmitted, forming a self-locking. The shaft on the worm wheel 10 rotates 90 degrees together, pushing the cam 13 to rotate to the initial position of the cam 12, and the initial cam 12 is located at the position of the cam 13. At this time, the longitudinal wheel 15 contacts the surface of the conveyor belt 4 and is used for the longitudinal sliding of the frame plate 6. After adjusting the distance of the frame plate 6 according to the predetermined width of the beam steel, the servo motor 8 continues to rotate 90 degrees to restore the cam 12 to its initial height. Figure 4 As shown, at this time, the transverse wheel 14 contacts the surface of the conveyor belt 4, reducing the friction between the frame plate 6 and the conveyor belt 4, thereby realizing the use of two functions, while the longitudinal wheel 15 is hidden in the frame plate 6.

[0043] See also Figure 6 As shown, the rotary welding assembly includes an electric push rod 20 slidably mounted on the top surface of the inner cavity of the processing chamber 2 through a linear guide rail, the pushing end of the electric push rod 20 is fixedly connected to an upper plate 21, a hollow plate frame 22 is connected below the upper plate 21, and a side of the hollow plate frame 22 is provided with a broken groove for vertically passing the electric clamp 30, the lower surface of the upper plate 21 is meshed with a driven gear through a main gear driven by a servo motor, and the outer part of the driven gear is meshed with a gear ring fixedly connected to the lower surface of the upper plate 21, and A welding gun 23 is installed at the bottom end of the middle shaft of the moving gear, facing the connection part between the steel component and the beam steel. When the steel component is flipped and pushed to the welding position of the beam steel, the electric push rod 20 pushes the upper plate 21 and the hollow plate frame 22 downward synchronously. After the broken groove passes through the outside of the electric clamp 30, the driven gear rotates evenly around the main gear for one circle. In this process, the welding gun 23 welds the connection part between the steel component and the beam steel, realizing the welding work of the beam steel and the steel component. Fixed-point automatic welding is highly efficient.

[0044] When the present invention is used, in order to adapt to the welding of beam steels of different widths, the distance between the two frame plates 6 is adjusted. First, the servo motor 8 drives the worm 9 to rotate 90 degrees, and the shaft on the worm wheel 10 rotates 90 degrees together, pushing the cam 2 13 to rotate to the initial position of the cam 12. At this time, the longitudinal wheel 15 contacts the surface of the conveyor belt 1 4 and is used for the longitudinal sliding of the frame plate 6. After adjusting the distance between the two frame plates 6, the servo motor 8 continues to rotate 90 degrees, so that the cam 12 returns to the initial height. At this time, the transverse wheel 14 contacts the surface of the conveyor belt 1 4, reducing the friction between the frame plate 6 and the conveyor belt 1 4, and realizing the use of two functions;

[0045] The beam steel is placed on the transmission component 1 for positioning and conveying, and arrives at the inner cavity of the processing chamber 2 with the transmission of the supporting roller 18. The driving member 34 starts to slide through the rotation of the screw rod 2 33. The two driving members 34 simultaneously drive the inclined block 35 to slide toward the middle of the tilting table 11, and the driving member 34 passes through the through groove 24 to ensure the smooth sliding of the inclined block 35. Since the slope surface of the tilting table 11 abuts against the inclined block 35, the elastic member 2 36 begins to compress at this time, and the pressure plate 19 slides in a limited position toward the middle direction on the surface of the transfer plate 17. The height of the pressure plate 19 during the sliding rises and is higher than the upper surface height of the supporting roller 18. The beam steel is clamped and fixed by the pressure plates 19 on both sides of the end to ensure its welding stability with the steel member.

[0046] The steel component is positioned and transported by the transmission component 2 to the limit flip push component for fixing. Then, it is flipped 90 degrees clockwise and rotated to a vertical state. At this time, the lower surface of the steel component is horizontally fitted with the upper surface of the beam steel. Then, the steel component is horizontally pushed by the limit flip push component to move it to the welding position for fixed-point welding. After that, the connection between the beam steel and the steel component is welded evenly by rotating the rotating welding component for one circle. Since the beam steel and the steel component are in a clamped state during welding, the accuracy of the welding point is improved, thereby improving the welding quality.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
