Abstract
The utility model relates to the field of turning tools, in particular to a grinding head lathe tool which is characterized by comprising a lathe tool clamping sleeve, a cutter bar and a grinding head. The grinding head is fixedly connected with the cutter bar through an end surface locking screw. An external of the lathe tool clamping sleeve is in a tetragonal body structure, a through-hole is formed in the interior of the lathe tool clamping sleeve, the cutter bar is matched with the through-hole in a plugged mode and the cutter bar and the through-hole are locked tightly through a radial locking screw which is arranged on the surface of the lathe tool clamping sleeve. The tetragonal body structure outside the lathe tool clamping sleeve is a clamping portion of a tool. An axial cooling hole is formed in the center of the cutter bar; a radial cooling hole of 45 degrees is formed at the tail end of the axial cooling hole. The number of the radial cooling hole is four, and the four radial cooling holes are evenly scattered on the circumference of the cutter bar. The grinding head lathe tool improves the processing surface quality, enlarges functions of numerical-control turning abrasive machining. The design of the indexable cutter bar and the cooling holes greatly prolong the service life of the grinding head which is reconditioned at one time. The grinding head lathe tool has the advantages of being simple in structure, convenient to operate and low in manufacturing cost.
Description
Technical field
The utility model relates to the cutting tool fields, is specially a kind of bistrique lathe tool.
Background technology
Lathe tool for turning processing, is mainly used in the revolving parts such as turning machine working shaft-like, dish class.In machining, the turning working (machining) efficiency is higher than grinding, but the turning machined surface quality will be lower than grinding.The cutter that the numerical control turning lathe is commonly used at present has billmpse tool, recessing bit, threading tool, internal lathe-tool etc., these lathe tools are all processed in the mode of turning, finished surface to the great surface quality requirement, also need the secondary operations such as polishing, grinding and specially treated, the numerical control turning machined surface quality is subject to certain limitation.
The utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of bistrique lathe tool.
Described a kind of bistrique lathe tool is characterized in that comprising lathe tool chuck, knife bar and bistrique, and bistrique is fixedly connected with knife bar by the end face lock-screw; Lathe tool chuck outside is the tetragonal body structure, lathe tool chuck inside arranges through hole, knife bar and through hole are pegged graft and are coordinated, and knife bar and through hole lock by the radially lock-screw that is arranged on the lathe tool jacket surface, and the tetragonal body structure of lathe tool chuck outside is the retaining part of lathe; The knife bar center is provided with axial Cooling Holes, and axially the end setting of Cooling Holes is the radial cooling hole of miter angle, and radial cooling hole is set to 4, and is evenly distributed on the knife bar circumference.
Described a kind of bistrique lathe tool is characterized in that being provided with pad between described end face lock-screw and knife bar.
Described a kind of bistrique lathe tool is characterized in that described end face lock-screw is soket head cap screw.
Described a kind of bistrique lathe tool is characterized in that the radially lock-screw of described lathe tool jacket surface is set to 3.
Described a kind of bistrique lathe tool is characterized in that the diameter of described radial cooling hole is less than the diameter of axial Cooling Holes.
The utlity model has following advantage:
1. the raising machined surface quality, utilize the grinding surface quality higher than characteristic and the numerical control turning machining functions of turning processing, can obtain the requirement of numerical control turning fine finishining great surface quality, and surface roughness can reach Ra 0.8;
2. expand the function of numerical control turning grinding, utilized the bistrique lathe tool can realize general-purpose grinder part grinding function at the numerical control turning lathe, expanded the field of numerical control turning processing;
3. the design of indexable knife bar and Cooling Holes has improved the service life that bistrique is once repaired greatly;
4. simple in structure, easy to operate, cheap for manufacturing cost.
Description of drawings

Fig. 2 is plan structure schematic diagram of the present utility model;
In figure: 1-lathe tool chuck; The 2-knife bar; The 3-bistrique; The 4-pad; 5-end face lock-screw; 6-is lock-screw radially; The axial Cooling Holes of 7-; The 8-radial cooling hole.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described further:
A kind of bistrique lathe tool, comprise lathe tool chuck 1, knife bar 2 and bistrique 3, bistrique 3 is fixedly connected with knife bar 2 by end face lock-screw 5, end face lock-screw 5 is soket head cap screw, locking outside cylinder thickness is 1 mm～2mm, can between end face lock-screw 5 and knife bar 2, pad 4 be set, pad 4 adopts non-metallic gasket, prevents that bistrique is damaged; Lathe tool chuck 1 outside is the tetragonal body structure, lathe tool chuck 1 inside arranges through hole, knife bar 2 and through hole are pegged graft and are coordinated, and knife bar 2 and through hole lock by the radially lock-screw 6 that is arranged on lathe tool chuck 1 surface, and the tetragonal body structure of lathe tool chuck 1 outside is the retaining part of lathe; Knife bar 2 centers are provided with axial Cooling Holes 7, and axially the end setting of Cooling Holes 7 is the radial cooling hole 8 of miter angle, and radial cooling hole 8 is set to 4, and is evenly distributed on knife bar 2 circumference.
Particularly, the cross-sectional shape of lathe tool chuck is the square of 20mm * 20mm or 25mm * 25mm, the centre is provided with through hole, and lathe tool chuck one side axis is provided with three radially lock-screw holes, is mainly used in the clamping knife bar and is convenient to lathe tool in the installation of numerical control turning lathe.It is that circular-arc square forms that knife bar left end profile can be four jiaos, and it is axially arranged with axial Cooling Holes, and the outside cylinder plane is provided with and is the equally distributed 45 degree radial cooling holes of 90 degree (radial cooling hole footpath less than axial coolant aperture); Knife bar right-hand member profile can be set to optical axis, in be provided with the screw hole that matches with the end face lock-screw, knife bar is mainly used in being connected of bistrique and lathe.When bistrique one lateral wearing, need not the reconditioning bistrique, as long as upset knife bar 90 degree just can continue to use, corresponding Cooling Holes cooling medium will continue to aim at bistrique work cutting zone and carry out cooling.
