Abstract
The utility model discloses a guiding and positioning hole expanding cutter which mainly comprises a cutter body; a fixed seat, a cutter head and a guiding and positioning rod are arranged on the cutter body from top to bottom in sequence; and the cutter head is spirally distributed at the periphery of the cutter body in the axial direction. The cutter has the advantages of simple structure, low manufacture cost, no washer, adjustment exemption, accurate positioning, and rapid mounting and cutter changing, and can effectively ensure the processing accuracy.
Description
Technical field
The utility model relates to the technical field of tools for machine tools, more particularly relates to a kind of tools for machine tools with guide-localization function.
Background technology
In mechanical processing process, lathe is a kind of important machine tools, at present, add man-hour utilizing lathe to do reaming, the orientation problem of broad is a very thing of trouble always, when broad is installed, need utilize pad to adjust positioning accuracy by range estimation, so not only waste time and energy, positioning accuracy also is difficult to improve, also have in order to improve positioning accuracy, cooperate special-purpose cutter to use together by means of sleeve with one heart, though positioning accuracy increases, but the complex structure of its whole cutter, the production cost height, same installation and tool changing also bother, and are difficult to adapt to the needs of existing market.
The utility model content
The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and production cost is low, exempts to use pad, exempts to adjust, install and tool changing quick, accurate positioning can effectively guarantee the guide-localization cornish bit of precision.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
The guide-localization cornish bit, it mainly is made of cutter hub, this cutter hub by last from being holder, cutter head and guide-localization bar successively down, described cutter head in axial direction in the shape of a spiral shape be distributed in around the cutter hub.
Described cutter head in axial direction is layered distribution.
Described cutter head constitutes by 2 to 5 layers.
Offer bit-withdrawing slot between each of described cutter head layer.
It also includes countersink, and direction perpendicular to axial direction offers the countersink installing hole on the described holder, and countersink is fixedly mounted in this countersink installing hole.
Offer locking hole perpendicular to the countersink installing hole on the described holder, this locking hole place is equipped with clamping screw.
Described holder upper end is provided with the installation screw thread.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, production cost is low, exempt to use pad, exempt to adjust, only need just can be very convenient and easily position by the guide-localization bar on the cutter hub, accurate positioning can effectively guarantee machining accuracy, installation and tool changing also faster only need just can be installed and tool changing work by the installation screw thread on the cutter hub more conveniently.
