Description

Technical Field

[0001] This utility model relates to the field of stepless welding stud technology, specifically a stepless welding stud head structure. Background Technology

[0002] Stepless studs, also known as stepless cylindrical head studs, are a type of special fastener used to connect steel structures and concrete composite components. Their core feature is the absence of a distinct step in the stud shank, resulting in a smooth, cylindrical shape. Combined with a cylindrical head, they achieve a rapid, high-strength connection to the steel substrate primarily through electric arc stud welding. The working principle involves using the high-temperature electric arc generated during welding to melt the stud shank end and the substrate surface. Under pressure, the two fuse together, forming a strong welded joint after cooling. This provides reliable anchorage for the subsequently poured concrete, ensuring the coordinated stress distribution of the steel-concrete structure.

[0003] In existing technologies, the welding head and fixed storage structure in stepless stud welding are based on a combination of a dedicated, single-specification welding head and a rigid storage tank. The clamping mechanism (such as a lotus chuck) and positioning guide sleeve of the welding head are fixed in size and can only match stepless studs of a specific diameter and length. The welding current, arc length and other parameters are also preset to fixed values ​​that are compatible with this model and cannot be quickly adjusted by the electronic control system. The storage structure is mostly a small fixed material tank that is bound to the specification of the welding head. The inner cavity size strictly corresponds to a single model of welding stud and can only store welding studs of the same specification by gravity stacking, lacking the ability to be compatible with multiple models.

[0004] Welding heads are usually designed with fixed specifications and can only be used with a single type of stepless welding stud. If the welding stud type needs to be changed, the welding head and the matching stud feeding assembly must be completely disassembled and replaced. This is not only cumbersome and time-consuming, but also requires the additional storage of multiple sets of special tooling, increasing equipment investment costs. It is also impossible to efficiently weld different stepless welding studs. To address the above problems, a new type of stepless welding stud welding head structure is proposed.

Furthermore, the welding distance of multiple welding heads can be adjusted through the controller, enabling welding of different plates, greatly improving the adaptability of the equipment to different welding needs and expanding the application scenarios.

X-axis moving components 2 and Y-axis moving components 5 are existing technologies, and their function is to drive the platform 17 to move horizontally, for example, as disclosed in patent publication number CN113359336A. A clamping component 16 is set in the middle of the top of the workbench 1. The clamping component 16 can clamp the plate, facilitating welding. The clamping component 16 is not an improved technology in this patent; it adopts existing technology, such as using multiple small cylinders, clamping plates, etc., to form a structure that can push the clamping plates to move relative to each other, thereby achieving the clamping function.

[0028] Reference Figure 2 and Figure 3A fixed plate 6 is fixedly connected to the front end of the platform 17. Each fixed plate 6 has a cylinder assembly 7 at its front end. The movement of the fixed plate 6 causes the cylinder assembly 7 to move synchronously. An insulating plate 8 is fixedly connected to the bottom of the cylinder assembly 7. The insulating plate 8 is insulating and can isolate the current conduction between the cylinder assembly 7 and metal components such as the guide block 10 and connecting block 11, preventing welding current from interfering with the normal operation of the cylinder assembly 7. The cylinder assembly 7 is a structure found in the prior art, comprising a cylinder barrel, piston, piston rod, sealing components, auxiliary components, etc. A guide rod 9 is fixedly connected to the output end of the cylinder assembly 7.

A feeder 14 is provided at the front end of the storage box 3. The feeder 14 is not an improved technology of this patent. Its function is to transmit the stepless welding nails to the connecting block 11 through the flexible hose. The feeder 14 uses a vibratory feeder to arrange and directionally transport the randomly piled stepless welding nails, so that the welding nails enter the nail feeding channel in a specific direction and order.

[0029] Working principle: First, the sheet metal is fixed by the clamping assembly 16. Then, the X-axis moving assembly 2 and the Y-axis moving assembly 5 drive the platform 17 to move to the designated position. An external flexible hose is used, with one end connected to the feeder 14 and the other end connected to the connecting block 11, so that the feeder 14 is connected to the corresponding connecting block 11. Through the operation of the feeder 14, the stepless welding studs in the storage box 3 enter the interior of the connecting block 11 through the flexible hose. Guided by the guide block 10 and the guide rod 9, the stepless welding studs enter the interior of the welding head 12. The structure 12 is in the prior art. The limiting mechanism in the welding head 12 limits the stepless welding stud, and then the stepless welding stud is moved up and down by the drive of the cylinder assembly 7. Finally, the welding work is carried out. Different types of stepless welding studs can be used for welding through different welding heads 12. The stepless welding studs in the storage box 3 can store the same type or different types of stepless welding studs. The controller 15 controls the adjustment of the welding distance of two or more of the four welding heads 12, so that different plates can be welded.
