Technical Field

[0001] This utility model relates to the field of welding production equipment technology, and in particular to a metal structure welding and assembly production equipment. Background Technology

[0002] With the continuous growth in demand for metal structure welding and assembly in fields such as steel structure buildings, bridges, ships, and new energy vehicles, traditional manual welding is no longer able to meet the needs of large-scale production due to problems such as low efficiency and large quality fluctuations. Existing welding production mainly relies on special machines and fixed-station robots to solve the automated welding of simple straight welds, but it lacks flexibility and is difficult to adapt to multi-variety small-batch production.

[0003] However, in the current technology, most existing welding assembly equipment relies on manual hand-held or simple clamp positioning, which makes the workpiece prone to horizontal displacement due to welding vibration, resulting in large welding position deviations. Furthermore, when manually aligning and splicing, the alignment accuracy of the two sets of workpieces depends entirely on the operator's experience, resulting in large errors and affecting the welding quality of the workpiece. Utility Model Content

[0004] The purpose of this invention is to address the problems that existing welding and assembly equipment relies heavily on manual hand-held operation or simple clamps for positioning, which leads to the workpiece being prone to horizontal displacement due to welding vibration, resulting in large welding position deviations. Furthermore, during manual alignment and splicing, the alignment accuracy of the two sets of workpieces depends entirely on the operator's experience, resulting in large errors and affecting the welding quality of the workpieces. Therefore, this invention proposes a metal structure welding and assembly production equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal structure welding and assembly production equipment, including a support frame, wherein two sets of support frames are provided, and a driving mechanism is installed on the bottom surface of the support frame to drive the two sets of support frames to move. Clamping mechanisms are installed on both sides of the support frame.

[0008] Preferably, the driving mechanism includes a stop block, a traction block, a motor, a lead screw, and a fixing frame. Two fixing frames are provided, and the fixing frames are fixedly connected to both ends of the stop block. The top surface of the fixing frame is provided with a guide groove, and the traction block is slidably connected to the inner wall of the guide groove.

[0012] 1. In this utility model, the pressure block is deflected by the second cylinder, and the limiting groove opened on its bottom surface wraps around the part of the workpiece to prevent the workpiece from sliding in the horizontal direction. This achieves precise and stable fixation of the metal structural parts, provides position guarantee for subsequent welding operations, reduces the error and safety risk of manual hand positioning, and, in conjunction with the two sets of support frames of the drive mechanism, moves closer or further away from each other to realize the alignment and splicing of the workpieces clamped on the two sets of support frames, thereby improving the accuracy of the welding position.

[0013] 2. In this utility model, by activating the cylinder installed on the bottom surface of the top plate, the top end of its telescopic rod passes through the outer wall of the support plate and is fixedly connected to the bottom surface of the lifting plate, which can drive the lifting plate to move up and down along the inner wall of the movable groove.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a metal structure welding and assembly production equipment, including a support frame 1. Two sets of support frames 1 are provided. A driving mechanism 3 is installed on the bottom surface of the support frame 1. The two sets of support frames 1 are driven to move by the driving mechanism 3. Clamping mechanisms 2 are installed on both sides of the support frame 1. The clamping mechanism 2 includes a second cylinder 21, a connecting block 22, a pressure rod 23, a movable rod 24, a fixed plate 25, and a pressure block 26. The second cylinder 21 is installed on the bottom surface of the fixed plate 25. One side of the fixed plate 25 is fixedly connected to the outer wall of the support frame 1. The connecting block 22 is fixedly connected to the top end of the telescopic rod of the second cylinder 21. One end of the pressure rod 23 is rotatably connected to the connecting block 22. The pressure block 26 is fixedly connected to the other end of the pressure rod 23. The two ends of the movable rod 24 are rotatably connected to the middle outer wall of the pressure rod 23 and the top end of the fixed plate 25, respectively. A limit groove 27 is opened on the bottom surface of the pressure block 26.

[0022] The specific settings and functions of this embodiment are described in detail below. One side of the fixed plate 25 is fixedly connected to the outer wall of the support frame 1, providing rigid support for the entire clamping mechanism 2 and ensuring that the mechanism will not shake due to force during clamping. The extension and retraction of the telescopic rod provides the power required for clamping: when the telescopic rod of cylinder 21 extends, it drives the connecting block 22 to move upward, providing a power source for the rotation of the pressure rod 23, and driving the pressure block 26 at the other end of the pressure rod 23 to move closer to the workpiece. The pressure block 26 is fixedly connected to the other end of the pressure rod 23, and the limiting groove 27 opened on its bottom surface can be adapted to the edge or protrusion of the metal structural part. During clamping, the limiting groove 27 can wrap around the part of the workpiece to prevent the workpiece from sliding in the horizontal direction, realizing the precise and stable fixation of the metal structural part, providing position guarantee for subsequent welding operations, reducing the error and safety risk of manual hand positioning, and at the same time, the rigid material of the pressure block 26 can ensure the uniform transmission of clamping force and avoid the workpiece from deforming due to excessive local force, which is especially suitable for metal structural parts with regular cross sections such as rectangles and circles.

[0023] Example 2: Figure 1 - Figure 4 As shown, the support frame 1 includes a base 11, a top plate 12, a support plate 13, a movable groove 14, a lifting plate 15, and a cylinder 16. The top plate 12 is fixedly connected to the top surface of the base 11, the support plate 13 is fixedly connected to the top surface of the top plate 12, the movable groove 14 is formed on the top surface of the support plate 13, the lifting plate 15 is movably connected to the inner wall of the movable groove 14, the cylinder 16 is installed on the bottom surface of the top plate 12, and the top end of the telescopic rod of the cylinder 16 penetrates through the outer wall of the support plate 13 and is fixedly connected to the bottom surface of the lifting plate 15. The drive mechanism 3 includes a stop block 31. The system includes a traction block 32, a motor 33, a lead screw 34, and a fixing frame 35. Two fixing frames 35 are provided. The fixing frames 35 are fixedly connected to both ends of the stop block 31. The top surface of the fixing frame 35 is provided with a guide groove. The traction block 32 is slidably connected to the inner wall of the guide groove. The top surface of the traction block 32 is fixedly connected to the bottom surface of the base 11. The lead screw 34 is rotatably connected to the inner side wall of the fixing frame 35. The traction block 32 is threadedly sleeved on the outer wall of the lead screw 34. The motor 33 is installed on the end face of the fixing frame 35. The output shaft end of the motor 33 is connected to one end of the lead screw 34 for transmission.

[0024] The overall effect of this embodiment is that the support plate 13 is fixed to the top surface of the top plate 12, and the movable groove 14 on its top surface provides sliding space for the lifting plate 15. When it is necessary to adapt to metal structural parts of different thicknesses, the cylinder 16 installed on the bottom surface of the top plate 12 is activated. The top end of its telescopic rod passes through the outer wall of the support plate 13 and is fixedly connected to the bottom surface of the lifting plate 15, which can drive the lifting plate 15 to move up and down along the inner wall of the movable groove 14. This can adapt to workpieces of different thicknesses, reduce tooling change time, improve equipment versatility, and accommodate thicker workpieces. When the cylinder 16 extends its telescopic rod, the lifting plate 15 moves upward, raising the workpiece height and placing the welding part in a position that is easy to operate. When the workpiece is thin, the telescopic rod retracts and the lifting plate 15 moves downward to avoid welding inconvenience due to the workpiece being too low. By starting the motor 33 installed on the end face of the fixed frame 35, the lead screw 34 rotates and drives the traction block 32 to slide along the guide groove, thereby driving the two sets of support frames 1 to move closer or further apart, realizing the alignment and splicing of the workpieces clamped on the two sets of support frames 1, and improving the accuracy of the welding position.

[0025] The usage and working principle of this device are as follows: The workpiece is placed on the top surface of the support plate 13 and the lifting plate 15 of the support frame 1. Based on the workpiece thickness, cylinder 16 is activated. The telescopic rod of cylinder 16 moves the lifting plate 15 up and down along the movable groove 14, bringing the welding area of ​​the workpiece to a preset height. Cylinder 16 is then closed. Based on the length of the metal structural component, the motor 33 of the drive mechanism 3 is activated. The motor 33 drives the lead screw 34 to rotate, and the traction block 32 slides along the guide groove of the fixed frame 35, moving the base 11 of the two sets of support frames 1, thus achieving clamping on the two sets of support frames 1. For workpiece alignment and splicing, cylinder 21 of clamping mechanism 2 is activated. The telescopic rod of cylinder 21 extends, driving the connecting block 22 to move upward. The pressure rod 23 rotates around the connection point with the connecting block 22, and the movable rod 24 unfolds accordingly until the limiting groove 27 on the bottom surface of the pressure block 26 wraps around the edge of the workpiece. After confirming stable clamping, the welding operation of the metal structural parts is carried out. After welding is completed, cylinder 21 is activated to retract the telescopic rod, and the pressure block 26 moves away from the workpiece. Then, cylinder 16 is adjusted to lower the lifting plate 15 as needed. Finally, the workpiece is removed, completing one work cycle.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
