Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an electron beam automatic welding tool. Background Art

[0002] Electron beam welding technology uses high-energy electron beams as a processing heat source, bombarding the metal at the joint of the weld with a high-energy density electron beam to make it melt quickly, and then quickly cool to achieve the purpose of welding. In the process of electron beam welding of pressed workpieces, there is a sequence for welding various parts of the workpiece. The parts welded first are prone to deformation and tension, resulting in gaps in the pressed fitting surfaces of the parts welded later, and the quality of the workpiece cannot be guaranteed.

[0003] After searching, the patent number is CN219632810U, which discloses an electron beam welding tool. A fixing flange is arranged on the surface of the positioning disk and the fixing flange is threadedly connected to the positioning disk. The welding part is pressed onto the plane of the substrate by rotating the fixing flange. An adjustment frame is arranged in the middle of the screw rod and a weld is arranged inside the adjustment frame. The welding part is moved to the weld of the adjustment frame, and the surface undulation of the welding part at the weld is adjusted by the reserved threaded holes on the frame. Bolts are used for tightening during press fitting. This arrangement solves the problem that the flatness of the product cannot be ensured after welding, ensures the sealing of the weld, and the dimensional deformation of the product after welding is within the dimensional requirement range, which solves the problem that the welding part will sink after welding. However, manual bolts are required for tightening during press fitting, which is inefficient and cannot ensure efficient production. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an electron beam automatic welding tool for the above-mentioned shortcomings, thereby overcoming the defect of low production efficiency in the prior art and achieving the purpose of high production efficiency.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an electron beam automatic welding tool, characterized in that: it includes a base, a first flange is provided below the base, and a sealing ring, a third flange, an inner sleeve and a welding protective cover are provided on the inner surface of the first flange in sequence from the outside to the inside;

[0006] A second flange is provided above the base, a protective cover is provided at the central through hole of the second flange, a positioning block is provided below the protective cover, a central protective cover connecting block is provided below the positioning block, a groove is provided at the lower part of the central protective cover connecting block, and springs are provided in the grooves.

[0007] Furthermore, a central protective cover adapter block is provided below the central protective cover connecting block;

[0008] One end of the spring is connected to the central protective cover connecting block, and the other end of the spring is connected to the central protective cover adapter block;

[0009] A lower limit plate is arranged between the base and the second flange plate, and an upper limit plate is arranged above the third flange plate.

[0010] Furthermore, the base is provided with a plurality of guide pins distributed circumferentially, and the base and the guide pins are interference fit.

[0011] Furthermore, a guide column is provided inside the guide pin, and the guide pin and the guide column are matched with a small gap.

[0012] Furthermore, the protective cover plate is loosely matched with the second flange and is fixedly connected by bolts;

[0013] The positioning block is interference-fitted with the second flange and is fixedly connected with the second flange by bolts.

[0014] Furthermore, a through hole is provided in the positioning block.

[0015] Further, the upper portion of the central protective cover connecting block cooperates with the through hole in the positioning block;

[0016] A bearing is arranged between the central protective cover connecting block and the through hole in the positioning block.

[0017] Furthermore, central axes of the positioning block, the central protective cover connecting block and the central protective cover adapter block are on the same straight line.

[0018] The utility model adopts the above technical scheme, and has the following advantages compared with the prior art: when in use, first fix the welding pressing block on the bottom of the electron beam automatic welding tool, then put the electron beam automatic welding tool into the welding chamber, fix the workpiece in the positioning seat, start the automatic processing program, and the positioning seat automatically rises. When the positioning seat drives the workpiece to rise to the set height, the workpiece contacts the welding pressing block and rises at the same time, and the electron beam program is started to start welding. After welding is completed, the positioning seat descends and the electron beam automatic welding tool returns to its original position.

[0019] When the positioning seat drives the workpiece to rise to the set height, the spring of the electron beam automatic welding tooling is squeezed and generates a reaction force on the workpiece. The workpiece is subjected to up and down squeezing force. By applying up and down squeezing force, thermal deformation can be offset or reduced during welding, so that the workpiece can better maintain its original shape after welding.

[0020] At the same time, the upper and lower extrusion pressures can increase the stability of the workpiece in the electron beam automatic welding tooling. During welding, the workpiece is supported by the extrusion force to prevent the workpiece from accidentally moving or shaking, which helps to ensure the precise alignment of the welding parts and reduce the problems of mismatch or gaps in the fitting surfaces caused by the movement of the workpiece.

[0021] In general, the reaction force generated by the spring of the electron beam automatic welding tooling on the workpiece can effectively control the deformation of the workpiece during the welding process and maintain the close contact of the fitting surfaces, thereby reducing the possibility of gaps on the fitting surfaces due to welding deformation, helping to improve the welding quality and the accuracy of the workpiece. At the same time, there is no need to manually tighten the bolts to clamp the workpiece. The positioning seat automatically rises to achieve automated clamping, achieving the purpose of high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
