Milling clamping tool for an irregular outward convex side face of round thin sheet with center hole

Abstract

The invention discloses a milling clamping tool for an irregular outward convex side face of a round thin sheet with a center hole. The milling clamping tool for the irregular outward convex side faceof the round thin sheet with the center hole solves the problem that an existing clamp cannot be adapted to milling of a small arc tooth arranged at the outward protrusion of a round thin sheet workpiece with the center hole. A vertical center through hole (2) is formed in a lower step of a stepped base block (1). A cylinder body (4) is movably arranged in the vertical center through hole (2). Acylinder lifting guide pin (6) is movably arranged in an upwards inclined spiral groove (8) of the side wall of a cylindrical sleeve (7). A center guide cylinder (10) is fixedly arranged at the centerof the top face of the cylinder body (4). The center guide cylinder (10) is movably connected with a rectangular supporting plate (14) in a sleeved manner. The top end of the center guide cylinder (10) penetrates through an inner side end guide cylinder guide hole (16) and then is connected with a workpiece center hole (25) of the workpiece (28) in a sleeved manner. The milling clamping tool forthe irregular outward convex side face of the round thin sheet with the center hole achieves rapid machining of the workpiece and meets the machining requirement for mass production.

Description

technical field [0001] The invention relates to a milling and clamping tool for thin slices, in particular to a clamping tool for milling irregular convex side surfaces of circular thin slices with central holes. Background technique [0002] Some circular sheet workpieces with a central hole are made of alloy copper sheets with relatively high prices. Considering the processing cost, such workpiece blanks are generally completed by stamping; On the side, sometimes the process requires irregular outward protrusions, and small arc-shaped teeth are arranged on the outward protrusions, and the arc-shaped teeth cannot be processed by stamping. If the method of wire cutting is used to process , it is necessary to reserve a large machining allowance, and remove a lot of material, which will cause a huge waste of material; in this case, it is generally considered that the combination of milling and stamping is more economical and practical, but it needs to be clamped during milling...
