Abstract
The utility model discloses a boring cutter and relates to the field of metal machining technology. The conventional double-blade heavy boring cutter has the disadvantages of lack of structural diversity, poor stability and difficulty in adjustment. The boring cutter comprises a cutter body and two cutter holders, cutting tools are fixed at the top ends of the cutter holders; one end of the cutter body is provided with guide rails; the cutter holders are provided with long holes; screws are installed fixedly to the cutter body after passing through the long holes; and sides of the cutter holders are provided with adjusting screws. The boring cutter has the advantage that: during locking of the cutter holders, the size after adjustment will not change and the adjusting precision is improved greatly.
Description
Technical field
The utility model belongs to the metal cutting processing technique field, is specifically related to a kind of double-blade adjustable rough boring tool for hole processing.
Background technology
The twolip rough boring cutter comprises that two tool rests are fixedly mounted on cutter hub, compares with the single-blade rough boring cutter, has two blades to participate in simultaneously cutting, and stock-removing efficiency is higher, and the radial load that acts on the cutting edge of two symmetries is cancelled out each other, and makes boring bar be difficult for producing vibration.Yet the twolip rough boring cutter is adjusted inconvenient, even after adjusting, in compaction process, size and the position of boring cutter easily change, and the poor stability of twolip rough boring cutter is adjusted extremely inconvenient.
The utility model content
The purpose of this utility model be exactly to solve that existing twolip rough boring cutter exists that structure is single, defective that poor stability and being difficult for is adjusted, provide a kind of and be easy to adjust, the double-blade adjustable rough boring tool of good stability.
For this reason, the utility model is by the following technical solutions: a kind of boring cutter, comprise cutter hub and two tool rests, cutter is fixedly installed in the top of tool rest, it is characterized in that: the end of described cutter hub arranges guide rail, slotted hole is set on tool rest, and screw passes slotted hole and is fixedly installed on cutter hub, and the side of tool rest is provided with the adjustment screw.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described two tool rests can be changed mutually, and two cutters are in heteropleural.
Process through correct grinding on the surface, contact site of described adjustment screw and screw.
When the utility model uses, tool rest is slipped in cutter hub along guide rail, be fixed on cutter hub with screw in compression, when needs carry out adjusted size, unclamp screw, this moment, tool rest can slide on guide rail, adjusted screw, and the adjustment screw is attached on the face of cylinder of screw, promote tool rest, be adjusted to the position that needs, tighten screw, complete adjusted size.
Use the utility model can reach following beneficial effect: the utility model is by connecting with guide rail between tool rest and cutter hub, tool rest can be free to slide on the guide rail at cutter hub when adjusting, adjust precision and greatly improve, when guaranteeing tool rest locking, the size of adjusting can not change.
