Description

Technical Field

[0001] This utility model relates to the field of tooling fixtures, and in particular to a flexible tooling fixture for welding cross-shaped structures. Background Technology

[0002] In many fields such as machinery manufacturing, steel structure processing, and power equipment, the cross-shaped structure, as an important connecting component, is widely used in the assembly of various load-bearing structures and support frames. Its welding quality directly determines the stability, load-bearing capacity, and service life of the overall structure. Therefore, the welding precision and efficiency of the cross-shaped structure has always been one of the core focuses of the industry. Cross-shaped structures are typically formed by the cross-welding of two or more components. During the welding process, it is essential to ensure precise cross-angles and uniform gaps between components. Simultaneously, the workpiece must be securely clamped to prevent weld misalignment, incomplete welds, or missed welds due to workpiece displacement or vibration, or workpiece deformation caused by welding heat input. These issues can negatively impact subsequent assembly accuracy and structural safety. Existing welding fixtures for cross-shaped structures are mostly specialized jigs. These jigs are usually custom-designed for specific sizes and specifications of cross-shaped workpieces. Their fixed structure cannot be flexibly adjusted according to changes in workpiece dimensions, resulting in poor versatility. When different specifications of cross-shaped workpieces need to be replaced during production, corresponding specialized jigs must be redesigned and manufactured, increasing production costs and preparation time. This makes it difficult to adapt to multi-variety, small-batch production and to quickly meet demand. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a more flexible tooling fixture for welding cross-shaped structures, which offers greater adjustment flexibility.

[0004] To achieve the above objectives, this utility model provides a flexible tooling fixture for welding cross-shaped structures, including a mounting table that can rotate circumferentially. The mounting table is provided with a frame, two adjusting parts, and several first connecting parts. The two adjusting parts can move laterally within the frame. The adjusting parts and the frame provide abutment support for the workpiece, and the adjusting parts can form a gap with the frame or adjacent adjusting parts for partial insertion of the workpiece. The several first connecting parts are detachably connected to the frame or adjusting parts, and the first connecting parts can clamp and position the workpiece with the frame or adjusting parts.

[0005] The advantages of the above technical solution are as follows: By using a circumferentially rotatable mounting platform, and setting a frame, two laterally movable adjustment parts, and a detachable first connecting piece on the mounting platform, the frame and adjustment parts cooperate to form a gap for inserting the cross-shaped workpiece to achieve abutment support. Then, the detachable connecting piece, together with the frame and adjustment parts, completes the workpiece clamping and positioning. Not only can the lateral position of the two adjustment parts be flexibly adjusted according to the size of the cross-shaped workpiece, effectively adapting to cross-shaped welding workpieces of different specifications and sizes, greatly improving the versatility and flexibility of the tooling, but it can also provide stable support and precise positioning for the cross-shaped intersection, effectively preventing workpiece displacement, angle distortion, and heat deformation during welding. At the same time, the circumferentially rotatable mounting platform can easily switch welding positions, eliminate welding blind spots, and clamping is convenient and fast without the need to change special fixtures, effectively shortening the production preparation cycle, reducing production costs, and significantly improving the welding accuracy and welding efficiency of the cross-shaped structure.

[0006] The present invention can be further configured such that: the frame has a laterally extending screw at one edge near the longitudinal end, the screw is screwed to the adjusting part, and the internal threads of the two adjusting parts for cooperating with the screw are arranged in opposite directions.

[0007] By further designing the frame, a transverse bidirectional threaded screw structure is adopted on the longitudinal edge of the frame. The two adjustment parts are screwed with the screw in opposite internal threads. Rotating the screw can drive the two adjustment parts to move laterally in opposite directions, which can quickly adapt to cross-shaped workpieces of different widths. There is no need to adjust them one by one. The adjustment operation is simple and the self-locking position of the threads after adjustment is stable and reliable.

[0008] The present invention can be further configured such that: the frame is rotatably provided with a laterally extending guide rod near both ends of the longitudinal direction, and the guide rod slides through the adjustment part.

[0009] By further designing the frame, horizontal guide rods are installed at both ends of the frame and slide through the adjustment part. This provides stable guidance and limit for the lateral movement of the adjustment part, ensuring that the adjustment part always slides smoothly along a straight line. This improves the smoothness of the adjustment movement and provides support and limit to ensure stability.

[0010] The present invention can be further configured such that: the frame includes a longitudinally extending side, and the adjustment part and the side are provided with a plurality of connecting holes, the connecting holes being through-holes, and the first connector is connected to the side or the adjustment part through the connecting holes.

[0011] By further designing the frame, through-holes are made on the longitudinal side and adjustment section of the frame. The connector can be flexibly installed at any position on the side or adjustment section. The installation point of the connector can be flexibly adjusted according to the shape and size of the cross-shaped workpiece and the position of the opening. It can adapt to the clamping requirements of cross-shaped workpieces with different structural forms. The clamping position is flexible and adjustable, and the flexibility is strong, which improves the positioning adaptation range and clamping stability of the tooling for the cross-shaped workpiece.

[0012] The present invention can be further configured such that: a plurality of second connectors are provided on the mounting platform, the main body of the second connectors is composed of flexible steel wire ropes, and the second connectors can be inserted through the connecting holes and pass through the holes of the workpiece.

[0013] By further designing the system, a flexible steel wire rope is used as the main body of the second connector. It can be connected and inserted into multiple connection holes and the workpiece's own holes for reinforcement. Utilizing the flexible and bendable characteristics of the steel wire rope, which can adapt to the shape and contour of the workpiece, it can serve as an auxiliary reinforcement, forming more stress points and support points, making the workpiece more evenly compressed, and avoiding squeezing damage and hard deformation to the workpiece surface caused by rigid clamping.

[0014] The present invention can be further configured such that: the first connecting member includes a bolt and an abutment block, the abutment block is provided with a long groove for the bolt to slide through, and the bolt can be connected to the connecting hole.

[0015] By further designing the structure, a bolt-fitted abutment block with a long groove is adopted. The position of the abutment block can be finely adjusted by sliding relative to the bolt through the long groove. The abutment position and clamping force can be flexibly adjusted according to the actual shape and size of the cross-shaped workpiece. The abutment positioning is more in line with the shape of the workpiece. The abutment block directly contacts and abuts the workpiece to form a clamping action. Attached Figure Description
