Description

Technical Field

[0001] The utility model relates to the technical field of welding workbenches, and more specifically, to a welding workbench suitable for tubular structures. Background Art

[0002] In modern industrial manufacturing, welding workbenches are indispensable equipment. They are mainly used to support and fix workpieces to be welded, ensuring stability and precision during the welding process. For general plate-like structures, the welding workbench can relatively easily fix and position workpieces through fixtures and positioning devices, enabling precise welding operations. However, when it comes to welding tubular structures, existing welding workbenches face many challenges. Since the circular cross-section of tubular workpieces is not easy to directly contact the flat welding table, it is difficult to firmly fix them with conventional fixtures. During the welding process, even a slight position deviation or insecure fixation may lead to a decline in welding quality and even cause safety accidents. Summary of the Utility Model

[0003] To make up for the above deficiencies, the utility model provides a welding workbench suitable for tubular structures to solve the above problems.

[0004] The utility model is implemented as follows:

[0005] A welding workbench suitable for tubular structures includes a welding table. The top of the welding table is provided with uniformly distributed threaded holes a.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4 shown, the present utility model provides a welding workbench applicable to a tubular structure, including a welding table 10. Threaded holes a 11 are evenly distributed in the top of the welding table 10. A plurality of first limit blocks 20, angle limit plates 30 and vertical fixtures 40 are movably arranged on the welding table 10. The first limit blocks 20 can stably place the tubular workpiece on the welding table 10. Combining with the vertical fixture 40 to apply a downward pressure on the top of the tubular workpiece to fix it on the workbench. At the same time, the angle limit plate 30 is used to provide a certain included angle for two tubular workpieces that need to be welded at a certain angle. The two right-angle plates of the angle limit plate 30 abut against the side of the tubular workpiece. At the same time, the vertical fixture 40 and the first limit block 20 respectively fix both sides of the angle limit plate 30, and finally complete the fixation of the angle. Through this structure, the alignment and fixation problems of the tubular workpiece are solved, ensuring the stability and safety of the welding process.

[0023] As shown Figure 2 As shown, a first pin 21 is provided at the bottom of the first limit block 20. The first pin 21 is movably arranged in the threaded hole a11 and can rotate at any angle around the first pin 21 as the axis. A right-angle groove 22 is formed at the top of the first limit block 20, so that the circular cross-section of the tubular workpiece abuts against the two surfaces of the right-angle groove 22, thereby achieving the effect of stable support. Therefore, by placing a plurality of first limit blocks 20 along the length direction of the bottom of the tubular workpiece, the tubular workpiece can be stably placed on the welding table 10.

[0024] As shown Figure 3 As shown, the angle limit plate 30 includes a first right-angle plate 31 and a second right-angle plate 32. One end of the first right-angle plate 31 and the second right-angle plate 32 is hinged, and a second pin 3102 is provided at the bottom of the hinged part. The second pin 3102 is movably arranged in the threaded hole a11.

[0025] Furthermore, a lower connecting part 3101 is provided at one end of the first right-angle plate 31, and an upper connecting part 3201 is provided at one end of the second right-angle plate 32. The upper connecting part 3201 and the lower connecting part 3101 are hinged to each other, and the second pin 3102 is arranged at the bottom center of the lower connecting part 3101.

[0026] Furthermore, a plurality of positioning grooves 3103 are formed on the two connecting plates of the first right-angle plate 31, and a plurality of positioning holes 3202 are formed on the two connecting plates of the second right-angle plate 32.

[0027] It should be noted that the width of the positioning groove 3103 and the diameter of the positioning hole 3202 are equal to the diameter of the threaded hole a11.

[0028] As shown Figure 4 As shown, the vertical fixture 40 includes a threaded tube 41, a swing arm 42 and a contact screw 43. One end of the swing arm 42 is provided with a connecting part a4201, and the bottom of the connecting part a4201 is a concave part. The top of the threaded tube 41 is rotatably arranged in the concave part. The other end of the swing arm 42 is provided with a connecting part b4202, and a threaded hole b4203 is formed at the top of the connecting part b4202. The contact screw 43 is threadedly connected to the threaded hole b4203.

[0029] It should be noted that the axial direction of the threaded hole b4203 is the same as the axial direction of the threaded tube 41, ensuring that the contact screw 43 is always perpendicular to the welding table 10, thereby applying a downward pressure to the tubular workpiece and firmly clamping it on the right-angle groove 22.

[0030] Furthermore, a handle 4301 is connected to the top of the contact screw 43, and a stop block 4302 is provided at the bottom of the contact screw 43.

[0031] As a preferred embodiment, the bottom of the stopper 4302 is an arc surface, a boss is provided on the top of the stopper 4302, a rotation hole is opened on the top of the boss, a side groove is provided on one side of the side wall of the rotation hole close to the bottom, the contact screw 43 is inserted into the rotation hole, a limiting piece is provided at its end, and the edge of the limiting piece is located in the side groove. The contact area with the tubular workpiece is increased through the arc surface, so as to better increase the clamping effect of the stopper 4302 on the tubular workpiece.

[0032] Specifically, the working principle of the welding workbench applicable to the tubular structure: a plurality of first limit blocks 20 are arranged at the bottom according to the shape of the tubular workpiece to be welded. The first limit blocks 20 are placed and rotated so that the opening direction of the right-angle groove 22 is the same as the node direction of the tubular workpiece to be contacted. Then, an appropriate number of angle limit plates 30 are selected, the first right-angle plate 31 and the second right-angle plate 32 are unfolded to make them contact the outer side of the pipeline workpiece. Then, a plurality of vertical clamps 40 are selected to clamp and fix the top of the pipeline workpiece. It should be noted that the vertical clamp 40 also takes into account the fixation of the first right-angle plate 31 and the second right-angle plate 32 to form a fixed angle to ensure that it can provide support for the side of the tubular workpiece. That is, a threaded tube 41 of a right-angle clamp is selected to pass through the positioning groove 3103 of the first right-angle plate 31 and be threadedly connected to one of the threaded holes a11. Then, the angle of the swing arm 42 is adjusted so that the stopper 4302 is directly above the tubular workpiece. Then, another right-angle clamp is selected to make the threaded tube 41 pass through the positioning hole 3202 on the second right-angle plate 32 and be threadedly connected to the threaded hole a11. It is necessary to ensure that at least one vertical clamp 40 on the first right-angle plate 31 and the second right-angle plate 32 fixes them, solving the problem that the circular cross-section of the tubular workpiece of the existing welding workbench is not easy to directly contact with the flat welding table 10, resulting in difficulty in firmly fixing it with conventional clamps. During the welding process, a small position deviation or insecure fixation will cause the welding quality to decline and even lead to safety accidents.

[0033] The above further describes the present invention with the help of specific embodiments. However, it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the present invention. Various modifications made by those of ordinary skill in the art after reading the above embodiments belong to the scope protected by the present invention.
