The existing milling cutter head either has many structural components with complex production and assembly process, or cannot mill both above and below the workpiece with fixed position, and needs to flip the workpiece after milling one side to mill the other side, or replace the symmetrical cutter head to mill the other side without moving the workpiece, which is time-consuming and laborious, and low in production efficiency. SUMMARY

[0003] To solve the above problems of the prior art, it would be advantageous to provide a milling cutter head for milling splicing plate welding integrated machine with fewer structural components, which saves time and labor in the milling process.

[0005] In the utility model, the first cutting edge arranged at the center of the waist of the cutter body can be used to mill the workpiece to be spliced for better splicing. The two second cutting edges arranged in mirror image can be used to mill the workpiece to be spliced on the upper surface or lower surface for welding. The two third cutting edges arranged in mirror image can be used to thin the upper surface or lower surface of the thicker workpiece when splicing two workpieces with different thicknesses into one large workpiece. In addition, the five cutting edges arranged as above, and the symmetrical arrangement of the two third cutting edges and the two second cutting edges, enable the milling cutter head to mill different surfaces of the workpiece without replacing the cutter head or flipping the workpiece, which greatly saves time and labor and improves production efficiency.

[0006] Further, the thinning installation surface is inclined by 20° towards the waist relative to the horizontal plane.

[0007] Through the above structure, the thick workpiece can be thinned to generate a 20° chamfer, so as to be flush with the thin workpiece at the joint.

[0008] Further, the thinning blade includes a plurality of thinning blades arranged along the circumference of the cutter body, each of which is installed on the thinning installation surface at an angle α of 3°-7° with respect to the tangential direction of the thinning installation surface, and the angle α is preferably 5°.

[0009] Through the above structure, the thinning blade can complete the thinning process of the thick workpiece.

[0010] Further, the plurality of thinning blades are arranged in two rows, and every two adjacent thinning blades are arranged in a circumferential staggered manner.

[0011] Through the above structure, the thinning process is more efficient.

[0012] Further, a chip groove is arranged between every two adjacent thinning blades on the thinning installation surface.

[0013] Through the arrangement of the chip groove, the accumulation of milling chips during the thinning process is avoided, which affects the thinning process.

[0014] Further, the bevel blade is arranged perpendicularly with respect to the thinning blade.

[0015] Through the above structure, the bevel blade is inclined at an angle of 20° with respect to the plumb surface, so that a 20° chamfer bevel can be milled on the workpiece, and a 40° welding bevel can be formed between the two workpieces.

[0016] Further, the bevel blade includes a plurality of bevel blades arranged along the circumference of the cutter body, each of which is installed at an angle β of 3°-7° with respect to the tangential direction of the center of the waist portion. Further, the plurality of bevel blades are arranged in two rows, and every two adjacent bevel blades are arranged in a circumferential staggered manner. Further, a chip groove is arranged between every two adjacent bevel blades on the center of the waist portion of the cutter body.

[0017] Through the above structure of the bevel blade, on the one hand, the bevel milling process can be efficiently completed, and on the other hand, the accumulation of milling chips is avoided.

[0018] Further, the flattening blade includes a plurality of flattening blades arranged along the circumference of the cutter body, each of which is installed at an angle θ of 3°-7° with respect to the tangential direction of the center of the waist portion, and the plurality of flattening blades are arranged in a row, and a chip groove is arranged between every two adjacent flattening blades.

[0019] By using the above-mentioned structural design for the grinding blade, we can ensure efficient completion of the grinding process on the one hand, and avoid the accumulation of milling chips on the other.

[0020] These and other aspects of the present invention will be more clearly illustrated by referring to the embodiments described below. Attached Figure Description

For example... Figure 8 A milling and welding machine 1000 with a milling cutter head 500 is shown. In this figure, the milling cutter head 500 is mounted on the milling unit 501 of the milling and welding machine 1000.

[0033] like Figure 1 As shown, in this embodiment, the milling cutter head 500 includes a cutter head body 50 in the shape of a flat hub and multiple cutting edges mounted on the cutter head body 50. The multiple cutting edges include a grinding cutting edge 51 located at the center of the waist of the cutter head body 50, two beveling cutting edges 53 located on the upper and lower sides of the center of the waist of the cutter head body 50 in a mirror-symmetrical manner on the upper and lower sides of the grinding cutting edge 51, and two thinning cutting edges 55 located on the thinning mounting surfaces 52 on the top and bottom of the cutter head body 50 in a mirror-symmetrical manner.

[0034] In this embodiment, the thinning mounting surface 52 is set to be inclined at 20° towards the waist relative to the horizontal plane, so that a 20° chamfer Φ can be generated on a thicker workpiece 61 (thickness dimension H2, for example, 30 cm thick). Specifically, in this embodiment, as... Figure 9 As shown, in this embodiment, when it is necessary to splice workpiece 61 and workpiece 63 (workpiece with a smaller thickness dimension H3, such as 20 cm thick) into workpiece 60, it is necessary to first thin the end of workpiece 61 that is close to workpiece 63. Thinning can be accomplished by the thinning blade 55 of the milling cutter head 500. A slope 610 is generated on this end of workpiece 61, and the chamfer Φ formed by the slope 610 relative to the surface of workpiece 61 is 20°.

[0035] like Figure 1 and Figure 5 As shown, and with reference Figure 2 and Figure 3 The thinning blade 55 includes a plurality of thinning blades 550 evenly distributed circumferentially along the blade body 50.

In addition, a chip removal groove 56 is provided between every two adjacent thinning blades 550.

[0036] like Figure 3As shown, in this embodiment, the beveling blade 53 is arranged perpendicularly to the thinning blade 55. That is, the beveling blade 53 is inclined at 20° relative to the plumb face (perpendicular to the horizontal plane), thus enabling the simultaneous milling of 20° bevels on both workpieces 61 and 62, thereby forming a 40° welding bevel δ at the connection between workpieces 61 and 63. Figure 9 As shown.

[0037] like Figures 1 to 3 as well as Figure 6 As shown, in this embodiment, the beveling cutting edge 53 includes a plurality of beveling blades 530 evenly distributed circumferentially along the cutter head body 50. Each beveling blade 530 is installed at an angle β of 3° to 7° relative to the tangential direction of the center sides of the waist, and this angle β is preferably 5°. For example... Figure 1 As shown, in this embodiment, multiple beveling blades 530 are arranged in two rows, and every two adjacent beveling blades 530 are staggered in the circumferential direction. A chip removal groove 54 is provided between every two adjacent beveling blades 530.

[0038] like Figure 1 and Figure 7 As shown, and with reference Figure 2 and Figure 4 In this embodiment, the grinding blade 51 includes a plurality of grinding blades 510 evenly distributed circumferentially along the blade body 50.
