Description

Technical Field

[0001] This utility model relates to the field of flange assembly technology, and in particular to a clamping fixture for spot welding of steel pipes and flanges of different lengths. Background Technology

[0002] Currently, the welding and fixing of steel pipes and flanges mainly relies on manual clamping. In actual production, to improve the efficiency of prefabrication welding, the steel pipe and flange are usually aligned first, and then fixed in position by spot welding before being transferred to the next processing area for full welding. Existing spot welding racks have simple structures and can only meet the spot welding of one specification of steel pipe, resulting in the need to set up multiple spot welding racks to meet different needs. This not only leads to high assembly costs but also occupies a lot of storage space. Utility Model Content

[0003] The purpose of this invention is to provide a clamping fixture for spot welding steel pipes and flanges of different lengths, thereby solving the aforementioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a clamping fixture for spot welding steel pipes and flanges of different lengths, including a workbench and a support assembly connected to the bottom surface of the workbench. Several support assemblies are connected to the workbench, and the spacing between two adjacent support assemblies is equal. Each support assembly includes an L-shaped plate with its bottom welded to the workbench. An arc-shaped groove is formed on the vertical end of the L-shaped plate, and second fixing holes are formed on the L-shaped plate on both sides of the arc-shaped groove. An mounting plate is connected to the top surface of one end of the workbench. An insertion hole is formed at the center of the mounting plate, and first fixing holes are formed at each of the four corners of the mounting plate.

[0006] Furthermore, the support assembly includes two symmetrically arranged support legs, the tops of which are connected to the two ends of the bottom surface of the workbench.

[0007] Furthermore, the bottom of the mounting plate is connected to the first support plate, one end of which is welded to the bottom surface of one end of the workbench.

[0008] Furthermore, a second support plate is welded to the bottom left end of the workbench.

[0009] Furthermore, two inclined triangular top plates are connected to the top surface of the horizontal end of the L-shaped plate, and the tips of the two triangular top plates are inclined toward the central axis of the arc-shaped groove.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0011] This utility model fixes the flange to the mounting plate with a pin and allows for the selection of a suitable L-shaped plate according to the length of different steel pipes. The selected L-shaped plate can support the end of the steel pipe, and the other end of the steel pipe is inserted into the flange. The position of the steel pipe is limited by two triangular top plates to prevent rotation. Then, electric welding is performed, which is efficient and convenient and reduces assembly costs.

[0018] like Figure 1-4 As shown, a clamping fixture for spot welding steel pipes and flanges of different lengths includes a workbench 1 and a support assembly connected to the bottom surface of the workbench 1. The support assembly includes two symmetrically arranged support legs 8, the tops of which are connected to the two ends of the bottom surface of the workbench 1.

[0019] The workbench 1 is connected to several support components, and the spacing between two adjacent support components is equal. Each support component includes an L-shaped plate 5 with its bottom welded to the workbench 1. An arc-shaped groove 6 is provided on the vertical end of the L-shaped plate 5. Second fixing holes 7 are provided on the L-shaped plate 5 on both sides of the arc-shaped groove 6. Two inclined triangular top plates 11 are connected to the top surface of the horizontal end of the L-shaped plate 5. The tips of the two triangular top plates 11 are inclined toward the central axis of the arc-shaped groove 6. The tips of the two triangular top plates 11 press against the outer wall of the steel pipe, which plays a supporting and limiting role.

[0020] A mounting plate 2 is connected to the top surface of one end of the workbench 1. The bottom of the mounting plate 2 is connected to the first support plate 9. One end of the first support plate 9 is welded to the bottom surface of one end of the workbench 1 to facilitate the installation of a flange.

[0021] The mounting plate 2 has an insertion hole 3 at its center and first fixing holes 4 at each of its four corners. The flange is fixed in position by means of the first fixing holes 4 and the pin.

[0022] A second support plate 10 is welded to the bottom left end of the workbench 1 to extend its length.

[0023] The operation process of this utility model is as follows:

[0024] In use, the flange is fixed to the mounting plate 2 by a pin, then one end of the steel pipe is inserted into the flange, and the other end of the steel pipe is placed in the arc groove 6, and then spot welding is performed.
