Abstract
A kind of clip type double trapezoidal thread lathe tool, it relates to a kind of double trapezoidal thread lathe tool, is specifically related to a kind of clip type double trapezoidal thread lathe tool.When the utility model processes the trapezoidal thread of double trapezoidal thread leading screw to solve existing monodentate threading tool, the problem that working (machining) efficiency is low.The utility model comprises cutter hub, blade and two holding screws, blade is arranged on the front end of cutter hub by two holding screws, the front end of cutter hub is provided with two the first projections, the front end of blade is provided with two the second projections, and the distance between two the first projections is identical with the distance between two the second projections.The utility model is used for field of machining.
Description
Technical field
The utility model relates to a kind of double trapezoidal thread lathe tool, is specifically related to a kind of clip type double trapezoidal thread lathe tool, belongs to field of machining.
Background technology
Leading screw is a kind of conventional drive disk assembly, single head trapezoidal threaded lead screw, double trapezoidal thread leading screw etc. is had by different instructions for use, for the processing of double trapezoidal thread leading screw, employing monodentate threading tool trapezoidal thread first head to double trapezoidal thread leading screw carried out machining in the past, and working (machining) efficiency is low.
Utility model content
When the utility model is the trapezoidal thread solving existing monodentate threading tool processing double trapezoidal thread leading screw, the problem that working (machining) efficiency is low, and then a kind of clip type double trapezoidal thread lathe tool is proposed.
The utility model is the technical scheme taked that solves the problem: the utility model comprises cutter hub, blade and two holding screws, blade is arranged on the front end of cutter hub by two holding screws, the front end of cutter hub is provided with two the first projections, the front end of blade is provided with two the second projections, and the distance between two the first projections is identical with the distance between two the second projections.
The beneficial effects of the utility model are: the utility model uses through reality, and effect is fine, not only ensure that the machining accuracy of double trapezoidal thread, also substantially increases working (machining) efficiency.This lathe tool adopts bidentate structure, and tooth pitch is consistent with the pitch of double trapezoidal thread, ensures machining accuracy, and owing to adopting bidentate cutter structure, two heads of leading screw trapezoidal thread are processed simultaneously, substantially increase working (machining) efficiency, and working (machining) efficiency improves nearly one times.Owing to adopting mechanical clamped cutting blade pattern, after tool wear tipping, only more need renew blade, avoid cutter entirety and scrap situation, save tool expense.
