Abstract
A reaming and extruding tool for machining holes comprises a tool bar and a cutting section, wherein the cutting section is divided into a reaming part in front and an extruding part at back, the outer diameter of the reaming part is smaller than that of the extruding part, the two parts are coaxial, inverted cones are arranged at the head end and the tail end, a group of blades are embedded in the tool body, and the blades are uniformly distributed along the circumference. The utility model is used for the finish machining in hole once accomplishes reaming and extrusion, not only the operation is simplified, improves the work efficiency, can effectively improve the spot facing work precision moreover.
Description
Technical field
The utility model relates to a kind of machined compound tool, in particular for the accurately machined hinge-squeezed cutter in hole.
Background technology
To surface quality and the higher hole of required precision, add and generally will pass through reaming, fraising, extruding three process man-hour, usually fraising, extruding all are to adopt special reamer and extruding cutter to finish respectively, this not only increases number of changing knife, make troubles to operation, reduce work efficiency, and twice clamping cutter, the clamping error is arranged unavoidably, influence the hole machining accuracy.
The utility model content
The technical problems to be solved in the utility model provides a kind of simplified control, and the hole that can improve work efficiency and hole machining accuracy processes hinge-squeezed cutter.
The technical solution of the utility model is: the hole processes hinge-squeezed cutter, comprise knife bar, segment of cutting, improvements are that segment of cutting is divided into ream part that is positioned at the cutter front end and the crimping section that is positioned at thereafter, and ream part external diameter is less than the crimping section external diameter, two parts coaxial line, two ends are provided with back taper.
Above-mentioned ream part and crimping section respectively have one group of blade to be embedded in the cutter hub, and blade evenly distributes along circumference; Ream part blade is 4, and the crimping section blade is 6; Ream part blade external diameter is than the little 0.05～0.06mm of crimping section blade external diameter; The edge of a knife position of crimping section blade is an arc surface.
The utility model lumps together reamer and extruding cutter, can finish fraising, extrusion process, simplified control simultaneously; Hinge, crowded two parts coaxial line cut with scissors afterwards earlier and squeeze, and reduce the clamping error, improve work efficiency and hole machining accuracy.And hinge, squeeze two parts two ends back taper is all arranged, guarantee that feed is smooth, can not damage workpiece during withdrawing, strengthen result of use.
