Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to an integrated milling tool for welding bevel structures. Background Technology

[0002] Because the weld strength of aluminum alloy castings is typically only 60% of that of the base material, the cleanliness of the weld surface is crucial. Furthermore, aluminum alloys have a low melting point, rapid heat transfer during welding, and high fluidity in molten aluminum. Therefore, weld bevels are usually designed for aluminum alloy castings to meet the required weld strength. Since the weld bevel structure of aluminum alloys has multiple machined surfaces, each surface needs to be machined individually using a milling cutter. Currently, existing milling cutters can only machine one weld surface at a time. Therefore, after machining each weld surface, a different size milling cutter is required, necessitating multiple cutter changes during the machining process. This complicates the factory's machining workflow and reduces processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an integrated milling tool for welding bevel structures, which can complete the milling of the welding bevel in a single pass, thereby improving milling efficiency.

[0004] The technical solution of the present invention is: an integrated milling tool for welding bevel structures, comprising a tool shank and a tool holder, one end of the tool shank being connected and fixed to the tool holder, and the other end of the tool shank being provided with milling edges, the milling edges including a welding end milling edge and a bevel milling edge, the welding end milling edge being located at the front end of the milling edges, a welding table milling edge being provided between the front end of the bevel milling edge and the welding end milling edge, the included angle between the bevel milling edge and the extension direction of the central axis of the tool shank being consistent with the angle of the welding bevel to be milled, a butt stop milling edge being provided at the rear end of the bevel milling edge, the butt stop milling edge being perpendicular to the central axis of the tool shank, a support table milling edge being provided at the rear end of the butt stop milling edge, and a support table stop milling edge being provided at the rear end of the support table milling edge.

[0005] Furthermore, the included angle α between the beveling cutting edge and the extension direction of the central axis of the tool holder is 35~45 degrees.

[0006] Furthermore, the height of the milling cutter for the mating stop is 0.5~1mm.

[0007] Furthermore, the length of the milling blade on the welding table is 5~10mm.

[0008] Furthermore, the length of the milling blade of the support table is 35~45mm.

[0009] Furthermore, both the milling edge of the welding table and the milling edge of the support table are parallel to the central axis of the tool holder.

[0010] Furthermore, the milling cutter for welding the weld neck is arc-shaped.

[0011] Furthermore, the radius of the welding end milling cutter is 25~30mm.

[0012] Furthermore, the tool holder is an ER series spring clip tool holder or a round shank heavy-duty tool holder.

[0013] The beneficial effects of adopting the above technical solution are as follows: Using this milling cutter, all structures such as the front support stop, front support platform, butt stop, weld bevel, welding platform, and weld termination can be milled on the workpiece in one pass. No tool changes are required during the milling process. Compared with ordinary milling cutters that require frequent changes of different specifications for milling, this reduces the complexity of the worker's operation and greatly improves the processing efficiency.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0016] Figure 2 This is a side view of the present invention. Detailed Implementation

[0017] See Figures 1 to 2An integrated milling cutter for welding bevel structures includes a cutter shank 1 and a cutter holder. One end of the cutter shank 1 is connected and fixed to the cutter holder. The cutter holder can be an ER series spring clip cutter holder or a round shank heavy-duty cutter holder, making the cutter shank 1 and the cutter holder detachably connected, facilitating the replacement of cutters of other sizes. The other end of the cutter shank 1 is provided with milling edges, including a welding end milling edge 3 and a bevel milling edge 4. The welding end milling edge 3 is located at the front end of the milling edge and is used to mill the welding end structure on the workpiece. In this embodiment, the welding end milling edge 3 is arc-shaped with a radius of 25~30mm, which can mill the arc-shaped welding end structure and avoid leaving sharp tool marks on the workpiece. A welding table milling blade 5 is provided between the front end of the beveling milling blade 4 and the welding end milling blade 3. This welding table milling blade 5 is used to mill the welding table on the workpiece. In this embodiment, the length of the welding table milling blade 5 is 5~10mm, ensuring that the welding table of the workpiece is flush with the outer surface of the workpiece, thereby ensuring that the dimensions of the weld bevel are consistent and guaranteeing the welding quality. The included angle between the beveling milling blade 4 and the extension direction of the central axis of the tool holder 1 is consistent with the angle of the welding bevel to be milled. The beveling milling blade 4 is used to mill the weld bevel on the workpiece, and the included angle α between the beveling milling blade 4 and the extension direction of the central axis of the tool holder 1 is 35~45 degrees. A butt stop milling blade 6 is provided at the rear end of the beveling milling blade 4. The butt stop milling blade 6 is perpendicular to the central axis of the tool holder 1. The butt stop is milled on the workpiece through the butt stop milling blade 6, so that the weld bevel, the butt stop and the workpiece form a "Y" shaped weld structure, which serves as the main fusion zone for welding. In this embodiment, the height of the butt joint stop milling blade 6 is 0.5~1mm to avoid excessive height of the butt joint stop on the workpiece, ensuring full penetration between the workpiece and the opposing part and guaranteeing welding quality. A support table milling blade 7 is provided at the rear end of the butt joint stop milling blade 6, and a support table stop milling blade 8 is provided at the rear end of the support table milling blade 7. In this embodiment, both the welding table milling blade 5 and the support table milling blade 7 are parallel to the central axis of the tool holder 1. The length of the support table milling blade 7 is 35~45mm, allowing the support table milling blade 7 to mill a forward support table for the workpiece, and the support table stop milling blade 8 to mill a forward support table stop for the workpiece, facilitating the assembly and fixation of the workpiece and the opposing part, and improving the strength of the welded structure.

[0018] When using this milling tool, the tool holder 1 of suitable size is assembled on the tool shank, and CNC milling is used to mill the side contour of the welded joint of castings, profiles and other parts. The applicable welded joint contours include circular cross-sections, rectangular cross-sections and irregular cross-sections. In one pass, the milling of all structures on the workpiece, including the front support table stop, the front support table, the butt stop, the weld bevel, the welding table and the weld termination, can be completed.

[0019] This milling cutter eliminates the need for tool changes during milling, unlike conventional milling cutters which require frequent changes of different sizes. This significantly reduces the complexity of the operation for workers and greatly improves machining efficiency. Furthermore, a set of milling cutters of different sizes can be manufactured to meet specific machining needs, allowing for the use of appropriate tools for different workpiece dimensions.
