Abstract
The utility model relates to a tool for grinding cone inner holes of a shell reamer. The tool for the grinding cone inner holes of the shell reamer solves the problems that clamping and alignment time is long and working efficiency is low when the inner holes are processed by a grinding shell reamer tool in the prior art. The tool for the inner holes of the grinding shell reamer cone comprises a cylinder body, a first boss, a second boss, a pressing plate and a plurality of connecting pieces; round holes are processed in one end face of the second boss, the pressing plate, the second boss, the first boss and the cylinder body are sequentially arranged from bottom to top, and the second boss, the first boss and the cylinder body are sequentially connected into a whole from bottom to top, the connecting pieces are evenly arranged between the pressing plate and the second boss, and the tool for the inner holes of the grinding shell reamer cone is used for the field of machining.
Description
Technical field
The utility model relates to a kind of grinding shell reamer awl endoporus specific purpose tool.
Background technology
Shell reamer is a kind of universal cutter (as the connection pin-and-hole of processing steam turbine) of fine finishining pin-and-hole, the pin-and-hole of especially machining large-sized specification (Φ is more than 60), and this cutter structure pattern is the most commonly used.When this cutter of processing, benchmark when 1: 30 internal taper hole of tapering is processing and use, the machining accuracy of this endoporus influences fraising machining accuracy and the effect thereof of this cutter, adopt four paws chuck clamping, centering in the past, and owing to be the fine finishining endoporus, required the centering precision higher, need in the centering 0.05mm, when this mode was processed endoporus, clamping, centering time were longer, and operating efficiency is very low.
The utility model content
The utility model is when solving in the prior art grinding shell reamer processing endoporus, and clamping, centering time are longer, the problem that operating efficiency is very low, and then a kind of grinding shell reamer awl endoporus specific purpose tool is provided.
The utility model is to address the above problem the technical scheme that adopts to be: described instrument comprises cylinder, first round platform, second round platform, pressing plate and a plurality of connector; One end face of second round boss is processed with circular hole, pressing plate, second round platform, first round platform, cylinder set gradually from the bottom to top, and second round platform, first round platform, cylinder are in turn connected into one from the bottom to top, are laid with a plurality of connectors between pressing plate and second round platform.
The beneficial effects of the utility model are: the time that has reduced the clamping centering by the utility model, operating efficiency has improved 10%-40% on the basis of existing technology, improved grinding shell reamer endoporus centering precision simultaneously, because during grinding, axial location and clamping have reduced the distortion in the processing, and the utility model is simple in structure, at the bottom of the cost, easy to use, quick, the characteristics that usability is strong.
