Abstract
A screw shaft tube boring process professional cutter is provided, which comprises a shank, a blade and a jbckscrew. The front end of the shank is provided with a cutter square hole, a screw hole is arranged on the shank above the cutter square hole, the blade is arranged into the cutter square hole, the jbckscrew is rotated into the screw hole and the jbckscrew is rotated tightly, the blade is fixed tightly on the shank, which forms a screw shaft tube boring process professional cutter. The utility model has the effective results that: firstly, economic, the original cutter is reformed into blade, the using rate can be improved more than 5 times; secondly, after the blade is arranged into the cutter square hole, the verticality adjustment of knife edge and the inner wall of holes in the screw shaft tube can be achieved, which makes the good contact between the edge of the blade and the inner wall of the holes to improve processing accuracy; thirdly, when in processing, the knife edge is level and vertical with the inner wall of the holes, and the roughness is good after finish marching, which can reach Ra1.6.
Description
Technical field
The utility model relates to process tool, particularly relates to marine stern axle tube bore hole processing dedicated tool.
Background technology
In the shipbuilding process, stern tube shaft pipe bore hole is a very important work progress.This project construction difficulty is big, requires machining accuracy height (the brearing bore circularity after the processing, cylindricity≤0.04mm; The adjacent step axiality of stern tube shaft pipe orifice Φ≤0.025mm; Brearing bore roughness after the processing reaches Ra3.2), size Control and tolerance control in the particularly last finishing tool process are very important.Mainly be to select 25mm * 25mm three Te Weike cutter sides to process in the finishing tool process in the past.Because the wearing and tearing of process cutter, cutter is repaired cutter side through emery wheel and is shortened, and very sharp knife side can not use again, and cutter side's purchasing price is more expensive, has increased processing cost, has also wasted cutter.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of machining accuracy height, the stern tube shaft pipe bore hole processing dedicated tool that can increase economic efficiency.
The technical scheme that adopts is:
Stern tube shaft pipe bore hole processing dedicated tool comprises handle of a knife, blade and jackscrew.The front end of handle of a knife is provided with the cutter square hole, and the handle of a knife of its cutter square hole top is provided with a hole, and described blade is packed in the cutter square hole, and jackscrew screws in the silk hole and also screws jackscrew, and blade is fastened on the handle of a knife, constitutes stern tube shaft pipe bore hole processing dedicated tool.
The good effect that the utility model is obtained is:
1, economy is changed system into blade with former cutter side, and utilization rate can improve more than five times.
2, blade is packed into and can be carried out the perpendicularity adjustment of blade and hole inwall behind the cutter square hole in the stern tube shaft pipe, and the blade blade is contacted well with the hole inwall, has improved machining accuracy.
3, the flat and upright opening inwall of process blade, roughness is good after the fine finishining, and roughness reaches Ra1.6.
