Abstract

An arc surface milling machine includes a worktable, a base and a backup plate. The worktable is assembled adjacent to the base. The backup plate is adjustably mounted on the base and positioned adjacent to the worktable. The worktable includes a work surface, an opposite bottom surface, and a mounting end. The base is assembled to the mounting end of the worktable. The work surface defines a concave wedge-shaped receiving space adjacent to the mounting end and forms a milling opening communicating with the work surface and the mounting end.

Claims

1. An arc surface milling assistant processing device, comprising:

a worktable comprising a work surface, a bottom surface opposite to the work surface, and a mounting end, the work surface defining a concave receiving space adjacent to the mounting end, thereby forming a milling opening communicating with the work surface and the mounting end;

a base assembled adjacent to and connected with the mounting end of the worktable, wherein the base comprises two substantially parallel support blocks and a standard plate connecting the two support blocks together;

the two support blocks are fixed to the mounting end of the worktable and respectively positioned at two sides of the receiving space; and

a backup plate adjustably mounted on the base and positioned adjacent to the worktable, thereby forming a tool assembling space together with the base and the worktable,

wherein, the backup plate comprises a wedge-shaped inclined mounting side surface;

the base defines an inclined mounting surface declining toward the work surface of the worktable and positioned adjacent to a top surface thereof;

the inclined mounting side surface of the backup plate resists against the inclined mounting surface of the base.

2. The arc surface milling assistant processing device as claimed in claim 1, wherein the backup plate further comprises an abutting surface, the abutting surface of the backup plate faces toward the work surface of the worktable.
