Description

Technical Field

[0001] The invention relates to the technical field of automatic welding equipment, and in particular to automatic welding equipment for truss bars. Background Art

[0002] Truss reinforcement refers to a frame structure composed of steel grids and diagonal bars in a concrete frame structure. It is mainly used to enhance the bearing capacity and seismic resistance of a building. It consists of three groups of steel bars: upper chord steel bars, lower chord steel bars and web bars, forming a triangular cross-section. It is usually connected by resistance welding and is widely used in important buildings such as high-rise buildings, bridges and subways. It can significantly improve the bearing capacity and stability of the building.

[0003] During the welding process of existing truss bars, the clamping and fixing effect is weak, resulting in the position where the chord steel bars and the web steel bars contact each other being offset when being squeezed during welding, which will make the welding current unstable and lead to poor weld quality, and will make the structure of the truss bars unevenly stressed, resulting in safety hazards of weld cracks. At the same time, when welding truss bars of different sizes, the bending size of the web steel bars is also changing, but the movement of the clamping and fixing device is relatively limited, and it cannot adapt to web steel bars with different bending angles, and the clamping device needs to adjust the working position one by one, making the process operation cumbersome, inefficient, and time-consuming. After the welding and assembly of the truss bars are completed, personnel are required to unload the materials. The finished truss bars are long, difficult to operate, and heavy. It is difficult for a small number of personnel to lift the unloading materials, which is prone to safety accidents. Therefore, the present application provides an automatic truss bar welding equipment to meet the needs. Summary of the invention

The chord rod 20 and the web rod 19 are arranged on one side of the upper chord rod 18; it also includes a clamping and fixing component 6, a clamping and fixing component 6 is arranged on the top of the operating platform 1, and the clamping and fixing component 6 is used to transport and clamp and fix the lower chord rod 20; it includes a pushing adjustment component 7, a pushing adjustment component 7 is installed at the bottom of the clamping and fixing component 6, and the pushing adjustment component 7 is used to push the welded truss reinforcement to facilitate unloading; it includes an equidistant adjustment component 8, an equidistant adjustment component 8 is arranged inside the operating platform 1, and the equidistant adjustment component 8 is used to clamp and fix the web rods 19 with different bending angles; a pushing adjustment component 7 is installed at the bottom of the clamping and fixing component 6, and an equidistant adjustment component 8 is arranged on one side of the clamping and fixing component 6; the clamping and fixing component 6 is installed on the rolling output track of the sliding gear 12, the baffle 2 is electrically connected to the command sensor 14, and the electric push rod 15 installed at one end of the web rod pushing seat 17 moves synchronously with the moving direction of the web rod pushing seat 17.

[0041] As an implementation method in this embodiment, Figures 6 to 9As shown, the clamping and fixing assembly 6 includes a clamping frame 61, which is mounted on the surface of the operating platform 1. A support cavity 66 is mounted at one end of the clamping frame 61, and a hole is arranged at one end of the support cavity 66. A plurality of groups of support cavities 66 are arranged equidistantly on the surface of the operating platform 1. A circular groove sleeve 62 is arranged on the inner wall of the clamping frame 61, and a ball 63 is arranged inside the circular groove sleeve 62. The outer edge diameter of the circular groove sleeve 62 is larger than the diameter of the ball 63. A spring 65 is arranged below the circular groove sleeve 62. The spring 65 is arranged at the bottom of the circular groove sleeve 62. A contact head 64 is installed at one end of the contact head 64, and a flip clamping seat 67 is installed below the contact head 64. There are multiple groups of flip clamping seats 67, and the flip clamping seat 67 at the bottom is fixed. When the lower chord rod 20 passes through the clamping and fixing assembly 6, the clamping frame 61 limits the lower chord rod 20. At the same time, the ball 63 arranged on the surface of the clamping frame 61 is rotated and pushed inside the circular groove sleeve 62 by the force driven by the movement of the lower chord rod 20, thereby assisting the lower chord rod 20 to move in a directional manner. At the same time, the multiple groups of balls 63 make the lower chord rod 20 move inside the adjacent ones, positioning the lower chord rod 20, and at the same time, the extension of the abutment head 64 prevents the lower chord rod 20 from breaking away from the balls 63 and sinking, so that the lower chord rod 20 can only move in the multiple groups of balls 63. When the motor 11 stops and the belly rod 19 is placed, the electric push rod 15 starts to drive the chord rod pressing seat 16 to move, so that the pressing notch on its surface is accurately pressed on the surface of the upper chord rod 18 and the lower chord rod 20, and then continues to push downward. When the upper flip clamping seat 67 is in contact with the surface of the flip clamping seat 67, the upper flip clamping seat 67 is turned inwardly against the surface of the lower chord rod 20 until it touches the lower flip clamping seat 67 and stops. At this time, multiple groups of flip clamping seats 67 clamp the lower chord rod 20 tightly, and the supporting cavity 66 firmly supports the clamping frame 61.

[0042] As an implementation method in this embodiment, Figures 7 to 10As shown, the push adjustment assembly 7 includes a bidirectional rack 71, which is meshed and connected to the bottom of the sliding gear 12, one end of the bidirectional rack 71 is meshed and connected to a gear 72, an internal threaded sleeve 73 is installed on the top of the gear 72, a chute cavity tube 75 is sleeved inside the internal threaded sleeve 73, a push head 76 is sleeved inside the chute cavity tube 75, a cylinder 74 is installed at the bottom of the push head 76, and the cylinder 74 is fitted with the internal threaded sleeve 73. When welding is completed, the command sensor 14 transmits a signal to the control center 9, and then the control center 9 controls the motor 11 to rotate in the opposite direction. When the motor 11 rotates in the opposite direction, the bottom meshes and connects The pushing adjustment assembly 7 starts to operate, and the two-way rack 71 starts to move. When the two-way rack 71 moves, it drives the gear 72 meshing at one end to rotate. The rotation of the gear 72 causes the internal threaded sleeve 73 installed on the top to rotate. When the internal threaded sleeve 73 rotates, the cylinder 74 rotates and moves in the internal thread. When the cylinder 74 moves, it moves up and down in the slide groove cavity 75. When the cylinder 74 moves up and down, the push head 76 pushes upward. At this time, the welded truss reinforcement is pushed by the push head 76, and the flip clamping seat 67 begins to flip, and then the truss reinforcement is separated from the clamping and fixing assembly 6 and is at the top.

[0043] As an implementation method in this embodiment, Figures 6 to 11As shown, the isometric adjustment component 8 includes a rocker 81, which is mounted at one end of the operating platform 1, a connecting rod 82 is mounted at one end of the rocker 81, a threaded sleeve 83 is threadedly connected to the surface of the connecting rod 82, a scissor bracket 84 is mounted on the surface of the threaded sleeve 83, the threaded sleeve 83 remains stationary inside the scissor bracket 84, the scissor bracket 84 and the connecting rod 82 are connected to each other, a moving rod 85 is mounted at one end of the scissor bracket 84, a web rod pushing seat 17 is mounted at the end of the moving rod 85 away from the scissor bracket 84, a fixed seat 86 is mounted on the top of the scissor bracket 84, a web rod bracket 87 is mounted on the top of the fixed seat 86, a clamping seat 88 is mounted on the top of the web rod bracket 87, a rotating shaft 89 is mounted at the bottom of the web rod bracket 87, a counter plate 810 is rotatably connected to the surface of the rotating shaft 89, and the operator swings the rocker 81, and the rotation of the rocker 81 drives the connecting rod 82 to rotate. At this time, the connecting rod 82 is pushed into the threaded sleeve 83 threaded on the surface When the connecting rod 82 rotates, the scissor bracket 84 is deformed, so that the fixed seat 86 at the top moves to the bending point of the web 19 and stops. At this time, the movement of the scissor bracket 84 drives the moving rod 85 connected at one end to move. When the moving rod 85 moves, the web push seat 17 connected at one end moves synchronously. At this time, the movement of the fixed seat 86 drives the web bracket 87 to move together. When the web 19 is placed on the top, the clamping seat 88 pushes the web 19 The web bar 19 is clamped, and at the same time, under the action of gravity, the web bar 19 tilts toward the upper chord bar 18. At this time, the bottom of the web bar 19 hits the abutment plate 810. The abutment plate 810 is tilted on the rotating shaft 89 at a certain angle due to the inclination of the web bar 19 and then stops. The top of the web bar 19 is close to one side of the upper chord bar 18, and then the web bar pushing seat 17 pushes and fixes the web bar 19, and then the welding truss manipulator 3 welds the intersection between the upper chord bar 18, the lower chord bar 20 and the web bar 19.

[0044] The working principle of the technical solution provided by the present invention is as follows:

[0045] First, before welding the truss reinforcement, check the surfaces of the upper chord 18, the web 19 and the lower chord 20 for rust removal and crack inspection, check the status of the welding truss manipulator 3, open the chord pressing seat 16 and the web pushing seat 17, and then adjust the data between the displacement sensor 13 and the command sensor 14 through the control center 9, start the motor 11 and place the upper chord 18 and the lower chord 20 on the surface of the sliding gear 12, the output of the motor 11 drives the rotation of the sliding gear 12, and the rotation of the sliding gear 12 drives the upper chord 18 and the lower chord 20 to be continuously transported to one end of the operating platform 1, the upper chord 20 moves to one end through multiple groups of support frames 10, and the lower chord 18 passes through multiple groups of clamping and fixing components 6 until it touches the baffle 2, and the baffle 2 transmits a power signal to the command sensor 14, and the command sensor 14 transmits a stop command. To the control center 9, then the motor 11 stops rotating. When the motor 11 stops rotating, the equidistant adjustment component 8 is adjusted to drive the web push seat 17 to move in the slide groove 21. After adapting to the bending size of the web 19, the web 19 is placed on the inner side of the lower chord 20 and the outer side of the upper chord 18. Then the electric push rod 15 is started. The electric push rod 15 pushes the chord pressing seat 16 to fix the upper chord 18 and the lower chord 20, and pushes the web push seat 17 to fix the web 19. At this time, the displacement sensor 13 transmits the welding point of the web 19 back to the command sensor 14, and the command sensor 14 transmits the data to the welding truss manipulator 3. Then the welding truss manipulator 3 welds the welding point, and the impurities generated flow to the slide 4 through the holes on the surface of the operating platform 1, and then flow into the dust collecting bin 5 through the slide 4 for collection.

[0046] When the lower chord rod 20 passes through the clamping and fixing assembly 6, the clamping frame 61 limits the lower chord rod 20. At the same time, the ball 63 arranged on the surface of the clamping frame 61 is rotated and pushed inside the circular groove sleeve 62 by the force driven by the movement of the lower chord rod 20, assisting the lower chord rod 20 to move in a directional manner. At this time, multiple groups of ball 63 make the lower chord rod 20 move inside its adjacent inner part, positioning the lower chord rod 20. At the same time, the extension of the contact head 64 prevents the lower chord rod 20 from detaching from the ball 63 and sinking, so that the lower chord rod 20 can only move within the multiple groups of ball 63. When the motor 11 stops and the belly rod 19 is placed, the electric push rod 15 starts to drive The chord rod pressing seat 16 moves so that the pressing notches on its surface are accurately pressed on the surfaces of the upper chord rod 18 and the lower chord rod 20 and then continue to push downward. At this time, the lower chord rod 20 squeezes the contact head 64 and contracts backward, and the spring 65 squeezes and contracts at the same time. Then the lower chord rod 20 begins to contact the flip clamping seat 67. When contacting the surface of the flip clamping seat 67, the upper flip clamping seat 67 is tightly attached to the surface of the lower chord rod 20 and flipped inward until it touches the lower flip clamping seat 67 and stops. At this time, multiple groups of flip clamping seats 67 tightly clamp the lower chord rod 20, and at the same time, the support cavity 66 firmly supports the clamping frame 61.

[0047] After the upper chord 18 and the lower chord 20 are clamped and fixed, the equidistant adjustment component 8 is adjusted according to the bending angle of the web 19. The operator swings the rocker 81, and the rotation of the rocker 81 drives the connecting rod 82 to rotate. At this time, the connecting rod 82 rotates in the threaded sleeve 83 threadedly connected on the surface. When the connecting rod 82 rotates, the scissor bracket 84 is deformed, so that the fixed seat 86 at the top moves to the inflection point of the web 19 and stops. At this time, the movement of the scissor bracket 84 drives the moving rod 85 connected at one end to move. When the moving rod 85 moves, the web push seat 17 connected at one end moves synchronously. The movement of the fixed seat 86 drives the web support 87 to move together. When the web 19 is placed on the top, the clamping seat 88 clamps the web 19. At the same time, under the action of gravity, the web 19 tilts toward the direction of the upper chord 18. At this time, the bottom of the web 19 hits the abutment plate 810. The abutment plate 810 is tilted on the rotating shaft 89 at a certain angle due to the inclination of the web 19 and stops. The top of the web 19 is close to one side of the upper chord 18, and then the web pushing seat 17 pushes and fixes the web 19, and then the welding truss manipulator 3 welds the intersection between the upper chord 18, the lower chord 20 and the web 19.

[0048] When welding is completed, the command sensor 14 transmits a signal to the control center 9, and then the control center 9 controls the motor 11 to rotate in the opposite direction. When the motor 11 rotates in the opposite direction, the bottom meshing connection push adjustment component 7 starts to operate, and the two-way rack 71 starts to move. When the two-way rack 71 moves, it drives the gear 72 meshing at one end to rotate. The rotation of the gear 72 causes the internal threaded sleeve 73 installed on the top to rotate. When the internal threaded sleeve 73 rotates, the cylinder 74 rotates and moves in the internal thread. When the cylinder 74 moves, it moves up and down in the slide groove cavity 75. When the cylinder 74 moves up and down, the push head 76 pushes upward. At this time, the welded truss reinforcement is pushed by the push head 76, and the flip clamping seat 67 begins to flip, and then the truss reinforcement is separated from the clamping and fixing component 6 and is at the top, which is convenient for the operator to unload.

[0049] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
