Abstract
The invention relates to an angle-adjustable turning tool. The angle-adjustable turning tool comprises a tool holder, a tool bar, a blade and a pressing plate, wherein the section of the tool holder is V-shaped; the pressing plate is reverse U-shaped; the tool holder is connected with the pressing plate through bolts to form a cavity for accommodating the tool bar; elastic layers are arranged both on the V-shaped surface of the tool holder and on one surface, in contact with the tool bar, of the pressing plate; steps are arranged on the two sides of the pressing plate; the blade fixed through a screw is arranged at the front end of the tool bar. The angle-adjustable turning tool has the characteristics of avoidance of phenomena of vibration and blade rolling, high simplicity, high production efficiency, adjustable angle and length of the tool bar, and the like.
Description
Technical field
The present invention relates to machinery knives technical field, be specifically related to a kind of lathe tool of angle adjustable.
Background technology
Turnery processing is the major part processing technology of mechanical manufacturing field.Generally, when carrying out turnery processing to workpiece, the lathe tool of different lathe tool angle need be selected for process system machining condition.Although lathe tool kind is more, for independent one lathe tool, its turning tool label angle such as anterior angle, relief angle is definite value.
With same lathe tool being carried out slightly, finish turning adds man-hour, the main angle of lathe tool, as anterior angle, relief angle and cutting edge inclination, should change with should turning accordingly to some extent, rough turnly should select less anterior angle greatly because of the depth of cut, finish turning then should select larger anterior angle etc., to add the sharpness of lathe tool, reduces surface roughness.Traditional lathe tool angle is once wear into, just immutable after installing, serious production efficiency, and pattern is single, and use cost increases.
Summary of the invention
For above-mentioned technical problem, the invention provides one and effectively prevent vibration and guillotine phenomenon when doing, and simply, the lathe tool of the angle adjustable that production efficiency is high.
Realize technical scheme of the present invention as follows:
A kind of lathe tool of angle adjustable, comprise tool rest, knife bar, blade and pressure strip, described tool rest cross section is V-structure, and pressure strip is for falling " recessed " shape, tool rest and pressure strip are bolted the cavity being formed with and placing knife bar, V-type face on tool rest and the one side of pressure strip that contacts with knife bar are all provided with elastic layer, and pressure strip both sides are provided with step, and knife bar front end is provided with by the fixing blade of screw.
Described elastic side is rubber, and advantage is that plasticity is good, and elasticity is strong, and effectively can protect tool rest, knife bar and pressure strip itself, be to be worn at adjustment in use.
Described step and pressure strip are structure as a whole, and step is provided with the installing hole of construction bolt, and tool rest is provided with thinks corresponding screwed hole with installing hole, and advantage simplifies structure, and use for convenience detach, is convenient to fastening pressure strip and tool rest.
Have employed such scheme, tool rest cross section is V-structure, can so that knife edge bar and rotation regulate its angle, pressure strip is connected formed cavity radial height and is less than knife bar diameter with tool rest, so just by tighting a bolt, elasticity of compression layer, reach the effect of fastening knife bar, also the cutters such as knife bar can be protected, prevent its displacement in the course of the work, precision is caused to have deviation so that scrap, in turning process, bolt can be unclamped after withdrawing, rotate the length that knife bar can adjust arbitrarily the front end of the equal angular size of lathe tool anterior angle and knife bar, after adjusting, fastening bolt can cut again again, simple to operate, easy to use, efficiently avoid vibration and guillotine phenomenon when doing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of Fig. 1;
In accompanying drawing, 1 is tool rest, and 2 is pressure strip, and 3 is knife bar, and 4 is step, and 5 is bolt, and 6 is elastic layer, and 7 is blade, and 8 is screw.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, as Fig. 1 and Fig. 2, a kind of lathe tool of angle adjustable, comprise tool rest 1, knife bar 3, blade 7 and pressure strip 2, described tool rest 1 cross section is V-structure, pressure strip 2 is for falling " recessed " shape, and tool rest 1 and pressure strip 2 are connected to form the cavity placing knife bar 3 by bolt 5, and the V-type face on tool rest 1 and the one side of pressure strip 2 that contacts with knife bar 3 are all provided with elastic layer 6, elastic layer on pressure strip is set to arc shape, match with knife bar, pressure strip 2 both sides are provided with step 4, and knife bar 3 front end is provided with by the fixing blade 7 of screw 8.
Described elasticity 6 side is rubber, spring or shell fragment, and advantage is that plasticity is good, and elasticity is strong, can effectively protect tool rest 1, and knife bar 3 and pressure strip 2 itself, can not be worn when adjustment in use.
Described step 4 is structure as a whole with pressure strip 2, and step 4 is provided with the installing hole of construction bolt 8, and tool rest 1 is provided with the screwed hole corresponding with installing hole, and advantage simplifies structure, and use for convenience detach, is convenient to fastening pressure strip and tool rest.
