Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a fixed fixture for welding two steel butt joints that facilitates multi-angle connection. Background Technology

[0002] With the widespread application of welding technology in various fields, the structural forms welded have become increasingly diverse. To meet the design requirements of various styles, welding multi-angle structures has become more complex. On construction sites, many square steel bars need to be welded together. Before welding, the pre-welded square steel bars are cut to specific angles and then manually joined together for welding. This process cannot be completed by a single person and requires multiple people to coordinate and position the welding work. During the welding process, poor weld quality often results from unstable joint fixing, especially when the joint angles of two square steel bars on site vary. Developing a fixing fixture suitable for various angles to improve welding quality and production efficiency has become a problem that needs to be solved on-site. Existing technologies have relatively complex procedures, low construction efficiency, and poor forming effects. Utility Model Content

[0009] Furthermore, an assembly groove is provided on the base; one end of the docking adjustment seat is rotatably disposed in the assembly groove via the deflection shaft.

Detailed Implementation

[0021] This embodiment discloses a fixing fixture for butt welding of two square steels that facilitates multi-angle docking, including a base 100, a docking adjustment seat 400 mounted on the base 100 via a deflection shaft 300, and arc-shaped guide rails 200 mounted on the base 100 and located at both ends of the docking adjustment seat 400; limiting rods 501 penetrating the arc-shaped guide rails 200 are respectively installed at both ends of the docking adjustment seat 400; locking nuts 500 for clamping and positioning the docking adjustment seat 400 are installed at the ends of the limiting rods 501; two clamping baffles I 101 are symmetrically installed on the base 100; two clamping baffles II 401 are symmetrically installed on the docking adjustment seat 400; and positioning mechanisms for holding workpieces are respectively installed on the clamping baffles I 101 and the clamping baffles II 401.

[0022] In use, the two workpieces 700 to be welded are positioned on the base 100 and the docking adjustment seat 400 respectively by the positioning mechanism. Since the workpieces 700 have already been cut with corresponding bevels, the docking adjustment seat 400 is then adjusted to rotate around the deflection shaft 300, so that the bevels of the two workpieces 700 are aligned. Then, by adjusting the two locking nuts 500, the docking adjustment seat 400 is clamped on the arc-shaped guide rail 200. Finally, the subsequent welding work is carried out.

[0023] In this embodiment, as Figure 2 As shown, an assembly groove 102 is provided on the base 100; one end of the docking adjustment seat 400 is installed in the assembly groove 102 through the deflection shaft 300 and the bearing; so as to flexibly adjust the deflection angle of the docking adjustment seat 400.

[0024] In specific implementation, the arc-shaped guide rail 200 is a semi-circular guide rail with an angle scale 201 pre-made on its outer side wall; the deflection angle of the docking adjustment seat 400 can be coarsely adjusted in advance according to the bevel angle of the workpiece 700.

[0025] In this embodiment, when applied to automated welding, a telescopic cylinder 600 for adjusting the deflection of the docking adjustment seat 400 is also installed on the base 100. The lower end of the telescopic cylinder 600 is mounted on the base 100 via a lower hinge seat 601, and its telescopic end is hinged to the back of the docking adjustment seat 400 via an upper hinge seat 602. The telescopic cylinder 600 automatically adjusts the welding angle to meet the welding requirements of an assembly line.

[0026] like Figure 3 and Figure 4As shown, the positioning mechanism includes a guide rod 800 passing through the clamping baffle I 101 or the holding baffle II 401, a limiting nut 801 and a guide seat 803 respectively installed at both ends of the guide rod 800; wherein a guide wheel 804 in contact with the workpiece is installed in the guide seat 803, and a clamping spring 802 for clamping the workpiece is also sleeved on the guide rod 800; the guide seat 803 is a U-shaped seat or an L-shaped seat.

[0027] In use, the workpiece 700 is pushed from one end of the clamping baffle I 101 or the holding baffle II 401 to the other end. During this process, the clamping spring 802 in the positioning mechanism increases the elastic force on the guide wheel 804 at the end of the guide rod 800, thereby achieving the clamping and positioning function of the workpiece 700, and making it convenient and flexible to pick up and put down.

[0028] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
