Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for steel structure splicing and welding. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of components such as beams, columns, and trusses made of steel sections and plates. Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings. To prevent displacement during the splicing and welding of steel structures, tooling fixtures are needed. However, existing tooling fixtures have at least the following drawbacks: 1. Existing tooling fixtures are not effective at fixing steel structures, leading to easy displacement during processing and reducing welding quality; 2. When welding steel structures, existing tooling fixtures are usually loosened after welding one side, then flipped over and fixed to weld the other side, making welding very inconvenient and reducing welding efficiency. Therefore, we introduce a new tooling fixture for splicing and welding steel structures. Utility Model Content

[0003] The main purpose of this utility model is to provide a tooling fixture for steel structure splicing and welding, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A steel structure splicing and welding assembly fixture includes a drive box. A drive mechanism is movably connected between the left and right walls of the drive box. A controller is fixedly connected to the middle of the front end of the drive box. A chip receiving tray is placed in the middle of the upper end of the drive box. Support plates are fixedly connected to the upper left and upper right parts of the drive box. Reinforcing plates are fixedly connected to the lower parts of the opposite surfaces of the two support plates. Adjusting cylinders are movably connected to the upper parts of the opposite surfaces of the two support plates through bearings. Adjusting wheels are fixedly connected to the left outer surface of the left adjustment cylinder and the right outer surface of the right adjustment cylinder. A drive belt is sleeved on the middle of the outer surface of the two adjusting wheels. Fixed frames are fixedly connected to the left and right ends of the two adjustment cylinders. Clamping mechanisms are movably connected between the upper and lower frame walls of the four fixed frames. Screws are movably connected to the front and rear ends of the four fixed frames through bearings. Fixed brackets are threaded to the outer surfaces of the eight screws.

[0006] Preferably, the clamping mechanism includes a positive and negative lead screw, an adjusting handle is fixedly connected to the middle of the lower end of the positive and negative lead screw, and clamping plates are threadedly connected to the upper and lower parts of the outer surface of the positive and negative lead screw. A limiting rod is movably connected between the rear parts of the opposite surfaces of the two clamping plates, and the upper and lower ends of the limiting rod are respectively fixedly connected to the upper and lower frame walls of the fixed frame. The upper and lower surfaces of the positive and negative lead screw are respectively movably connected to the upper and lower frame walls of the fixed frame through bearings.

[0007] Preferably, the distance between the rear end face of the positive and negative lead screws and the front end face of the limiting rod is greater than the inner diameter of the adjusting cylinder, the length of the screw is smaller than the distance between the lower end face of the fixed frame and the upper end face of the drive box, and the fixed frame is configured as a rectangular frame.

[0008] Preferably, the driving mechanism includes two fixed plates. A dual-head motor is provided between the middle of the opposite surfaces of the two fixed plates. The two output ends of the dual-head motor pass through the opposite surfaces of the two fixed plates and are fixedly connected to drive shafts. The opposite surfaces and outer surfaces of the two drive shafts are movably connected to the opposite surfaces of the two fixed plates and the wall of the drive housing through bearings.

[0009] Preferably, the dual-head motor is electrically connected to the controller, and the diameter of the drive wheel is smaller than that of the adjustment wheel.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In this utility model, by setting a fixing frame and a clamping mechanism, the two clamping plates are driven to move towards the middle by rotating the positive and negative screws, so that the steel structure can be clamped from the top and bottom. Then, by rotating the screw, the fixing frame is pushed towards the middle, so that the steel structure can be clamped from the front and back. This strengthens the fixing effect of the steel structure, thereby improving the stability of the steel structure and ensuring the welding quality of the steel structure.

[0012] 2. In this utility model, by setting a driving mechanism, two drive shafts are driven to rotate synchronously by a double-headed motor, and then the drive wheel drives the adjustment wheel to rotate by the drive belt. This allows the adjustment cylinder to stably drive the steel structure to rotate, which facilitates the rotation and welding of the steel structure, making the welding process of the steel structure more convenient and efficient.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A steel structure splicing and welding assembly fixture includes a drive box 1. A drive mechanism 2 is movably connected between the left and right walls of the drive box 1. A controller 3 is fixedly connected to the center of the front end of the drive box 1. A chip receiving tray 4 is placed in the center of the upper end of the drive box 1. Support plates 5 are fixedly connected to the upper left and upper right parts of the drive box 1. Reinforcing plates 6 are fixedly connected to the lower parts of the opposite surfaces of the two support plates 5. Adjusting cylinders 7 are movably connected to the upper parts of the opposite surfaces of the two support plates 5 through bearings. The left side is adjustable. Adjusting wheels 8 are fixedly connected to the left and right sides of the outer surface of the cylinder 7. A drive belt 9 is sleeved on the middle of the outer surface of the two adjusting wheels 8. Fixed frames 10 are fixedly connected to the left and right ends of the two adjusting cylinders 7. A clamping mechanism 11 is movably connected between the upper and lower frame walls of the four fixed frames 10. Screws 12 are movably connected to the front and rear ends of the four fixed frames 10 through bearings. Fixed brackets 13 are threadedly connected to the outer surfaces of the eight screws 12.

[0023] In this embodiment, the clamping mechanism 11 includes a positive and negative lead screw 111. An adjusting handle 112 is fixedly connected to the middle of the lower end of the positive and negative lead screw 111. Clamping plates 113 are threadedly connected to the upper and lower parts of the outer surface of the positive and negative lead screw 111. A limiting rod 114 is movably connected between the rear parts of the opposite surfaces of the two clamping plates 113. The upper and lower ends of the limiting rod 114 are respectively fixedly connected to the upper and lower frame walls of the fixed frame 10. The upper and lower parts of the outer surface of the positive and negative lead screw 111 are respectively connected to the upper and lower frame walls of the fixed frame 10 through bearings. The wall-penetrating movable connection; the distance between the rear end face of the positive and negative screw 111 and the front end face of the limiting rod 114 is larger than the inner diameter of the adjusting cylinder 7, which is conducive to the insertion and placement of the steel structure. The length of the screw 12 is smaller than the distance between the lower end face of the fixed frame 10 and the upper end face of the drive box 1, so that the screw 12 does not affect the rotation of the fixed frame 10. The fixed frame 13 is set as a rectangular frame, which makes it easy to limit the fixed frame 13 on the frame wall of the fixed frame 10, and the fixed frame 13 does not contact the outer surface of the positive and negative screw 111 and the limiting rod 114, and does not affect the movement of the fixed frame 13.

[0024] In this embodiment, the drive mechanism 2 includes two fixed plates 21. A dual-head motor 22 is provided between the middle of the opposite surfaces of the two fixed plates 21. The two output ends of the dual-head motor 22 pass through the opposite surfaces of the two fixed plates 21 and are fixedly connected to drive shafts 23. The opposite surfaces and outer surfaces of the two drive shafts 23 are movably connected to the opposite surfaces of the two fixed plates 21 and the wall of the drive box 1 through bearings. Drive wheels 24 are fixedly connected to the opposite surfaces of the two drive shafts 23. The dual-head motor 22 is electrically connected to the controller 3, which can flexibly control the opening and closing of the dual-head motor 22. The diameter of the drive wheel 24 is smaller than that of the adjusting wheel 8. The drive of the drive wheel 24 can slow down the rotation of the adjusting wheel 8.

[0025] It should be noted that this utility model is a tooling fixture for steel structure splicing and welding. During use, the two steel structures to be welded are first inserted into the two adjusting cylinders 7 respectively. Then, rotating the adjusting handle 112 drives the positive and negative screws 111 to rotate, causing the two clamping plates 113 to move stably towards the center under the guidance and limitation of the limiting rod 114. This allows for clamping of the steel structure from above and below. Then, rotating the screw 12 pushes the fixing frame 13 towards the center, allowing for clamping of the steel structure from the front and back. Furthermore, the fixing frames 10 located at both ends of the adjusting cylinders 7 enhance the fixing effect of the steel structure, ensuring stable operation during processing. The process is less prone to displacement, thus improving the stability of the steel structure and effectively ensuring the welding quality. When welding one side of the steel structure is completed and welding of the other side is required, the controller 3 can control the dual-head motor 22 to start, causing the two drive shafts 23 to drive the two drive wheels 24 to rotate synchronously. Then, through the synchronous transmission of the two drive belts 9, the two adjusting wheels 8 drive the adjusting cylinders 7 to rotate, which can stably drive the two steel structures to flip over, making the welding process of the steel structure more convenient and efficient. This facilitates welding of the other side of the steel structure after flipping, and also improves the welding efficiency of the steel structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
