[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The utility model provides Figure 1-8 The illustrated welding fixture for the machining center main frame includes a fixture body for fixing the machining center main frame 6 and auxiliary components for facilitating welding. The fixture body includes a shaped door contact plate 1, a detachable shaped door contact plate 2 being provided at the top of the shaped door contact plate 1, and a detachable center column support frame 4 being provided at the top of the shaped door contact plate 2.

[0031] The top of the special-shaped door contact plate 1 is also provided with a detachable form-position reinforcement rib 1 3 and a form-position reinforcement rib 2 5. The main frame 6 of the machining center is located at the top of the special-shaped door contact plate 2 2 during welding, and the center column support frame 4 is supported at the center position of the main frame 6 of the machining center. The main frame 6 of the machining center is clamped between the form-position reinforcement rib 1 3 and the form-position reinforcement rib 2 5 during welding.

[0032] The various components of the tooling body are made by laser cutting. Laser cutting is accompanied by welding position lines and positioning slots. The various components are assembled through the slots and lines. After completion, the joints are welded using carbon dioxide gas shielded welding. After that, the tooling body is flattened and shaped to ensure that the overall size of the tooling is qualified and the deformation is reduced.

[0033] The assembled tooling body can be placed directly on the welding platform to ensure the plane position accuracy of the tooling. During the welding process, the main frame 6 of the machining center is fixed with bolts through the mounting holes of the special-shaped door contact plate 1 and the special-shaped door contact plate 2 to ensure the relative position and size of each part are correct. The problem points are checked and the welding size and flatness, verticality, position and other requirements of the components are accurately guaranteed. Finally, the other components are fastened to the tooling body with bolts, which can effectively control welding deformation.

[0034] This method can greatly improve the welding qualification rate of such components, effectively limit the welding position and size after forming of each welding unit, and lower the welding skill threshold of welders. The tooling can also be placed on the welding robot workbench to realize batch operation. When the robot is automatically welding, the tooling body can be directly installed on the work platform. When manual welding is performed, the tooling body can be installed on the auxiliary components, and then the auxiliary components can be installed on the work platform.

[0035] During manual welding, it is necessary to provide convenience for the welders, such as Figure 1 、 5 As shown in Figure 6, the auxiliary component includes a base 7, a turntable 8 is provided on the top of the base 7 through a rotating shaft, and the special-shaped door contact plate 1 is detachably provided on the top of the turntable 8. The direction of the tooling body during the welding process can be adjusted by rotating the turntable 8.

[0036] A vertical plate 11 is fixed to the top of the base 7, and a positioning bolt 12 is provided on the vertical plate 11 through a thread. When the positioning bolt 12 is tightened, the position of the turntable 8 can be fixed, and the position of the main frame 6 of the machining center can be fixed;

[0037] A positioning hole 10 is formed at the outer end of the turntable 8 . When the main frame 6 of the machining center is in the initial position, one end of the positioning bolt 12 is inserted into the positioning hole 10 .

[0038] When manual welding work is performed, the tooling body is located at the top of the turntable 8, and the turntable 8 can rotate at the top of the base 7 to adjust the direction of the machining center main frame 6 so that the machining center main frame 6 can be welded from various directions and positions. During the adjustment process, tightening the positioning bolts 12 can fix the turntable 8 and then fix the position of the machining center main frame 6.

[0039] The base 7 needs to be fixed on the working platform, such as Figure 5 、 7 As shown, an annular groove 13 is provided at the bottom end of the base 7, and two sealing rings 14 are fixedly provided at the bottom end of the base 7. The open end of the annular groove 13 is located between the two sealing rings 14, and an air duct communicating with the annular groove 13 is fixed at the top end of the base 7. After the air inside the annular groove 13 is extracted through the air duct, the base 7 can be adsorbed and fixed on the work platform through the annular groove 13.

[0040] After the base 7 is placed on the work platform, the sealing ring 14 is in close contact with the work platform, thereby closing the open end of the annular groove 13. The air inside the annular groove 13 is then extracted through the air duct, and the negative pressure of the annular groove 13 can be used to adsorb and fix the base 7 on the work platform, thereby improving the stability of the auxiliary component.

[0041] Manual welding workers also need to be protected, such as Figure 1 、 8 As shown, a protective component 9 is provided on the top of the base 7, and the protective component 9 is located on the front side of the base 7. The protective component 9 includes a baffle 903, and the baffle 903 is inlaid with welding goggles 904 for protecting the eyes;

[0042] A plurality of fans 905 are provided at the bottom of the welding goggles 904. The fans 905 are embedded in the baffle 903. The fans 905 drive the air flow to blow the harmful gases generated during the welding process to the side away from the human body.

[0043] The protective assembly 9 also includes a support frame 901 installed on the top of the base 7 by bolts, and an adjustment frame 902 is provided on the top of the support frame 901 through a rotating shaft. The baffle 903 is arranged inside the adjustment frame 902 and is movably connected to the inner wall of the adjustment frame 902 through a damping rotating shaft. The direction of the welding goggles 904 can be adjusted by rotating the adjustment frame 902 and the baffle 903.

[0044] When manual welding is performed, the welded parts on the main frame 6 of the machining center are observed through the welding goggles 904, which can effectively protect the welder's eyes and avoid damage to the eyes caused by strong light during welding. The protective component 9 is fixed on the base 7 and does not need to be held during welding, making it more convenient to use. At the same time, the fan 905 is turned on, and the fan 905 drives the air flow to blow the harmful gases generated by the main frame 6 of the machining center during welding to the side away from the welder, avoiding the harmful gases being inhaled into the human body and causing harm.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
