Abstract
A tool for removing burr at inner orifice is provided. The tool is composed of a cutter rod and a cutter. In the cutter part, 3-6 cutter blades are uniformly arranged on the excircle of a cutter body circumferentially, a guide ring is arranged at one end of the cutter body, and a radial cylindrical pin is arranged in the inner hole of the cutter body; in the cutter rod, a transverse handgrip is arranged at one end of a cutter handle, an L-shaped open groove is arranged at the other end, width of the open groove is equal to the diameter of the cylindrical pin; the cutter blades are integrated with the cutter body by welding, and the cutter handle is a hollow shaft. The utility model is applicable for removing burr from an inner orifice of a specific part such as a case body and a plate, the cutter and the cutter rod are respectively arranged via the inner orifice and an outer orifice, the handgrip is rotated to scrap the burr on the inner orifice uniformly. The utility model is not restricted by structure of parts, and has the advantages of good effect, high efficiency and convenient operation.
Description
Technical field
The utility model relates to a kind of instrument that is used for casing or the inboard aperture deburring of plate.
Background technology
At mechanical processing industry, usually meet the jagged problem removed of needing in the inboard aperture of some casings or platen type component, owing to be subjected to the restriction of parts space structure, operating difficulties, not only efficient is low but also be difficult for clean with oilstone commonly used or file deburring.
The utility model content
It is a kind of easy to operate that the purpose of this utility model is to provide, efficient height, the inboard aperture deburring tool that deburring is effective.
The technical solution of the utility model is: this instrument partly is made up of knife bar part and cutter, the knife bar part is made of handle of a knife and handle, the cutter part is by cutter hub, blade, straight pin constitutes, described blade has 3～6, along circumferentially being evenly distributed on the periphery of cutter hub, one end of cutter hub is a guide ring, described straight pin radially is arranged in the cutter hub endoporus, the edge of a knife of each blade is positioned on the same taper seat with the guide ring coaxial line, the vertex of a cone of this circular cone is towards guide ring one end, and described handle is arranged in the radial direction through hole of handle of a knife one end, and the handle of a knife other end has " L " shape open slot, its groove width is consistent with above-mentioned straight pin diameter, and handle of a knife becomes little matched in clearance with the cutter hub endoporus.
Above-mentioned blade and cutter hub are integrally welded; Handle of a knife is a hollow shaft.
During use, the cutter part is put into from the opening part of casing or the bottom of plate, the inboard of guide ring from the hole inserted in the hole, make blade conical surface contact aperture, then handle of a knife upper shed groove is aimed at the straight pin of cutter part, handle of a knife is inserted the cutter hub endoporus, and turning handle slips on the handle of a knife in the L shaped groove straight pin, continue turning handle in the same way, and upwards mention the knife bar part, then burr is removed in the inboard aperture of the balanced scraping of blade; Behind the end-of-job, the backwards rotation handle takes out knife bar part and cutter part.This tool construction is simple, and is easy to operate, is particularly useful for the deburring in the inboard aperture of some specific workpiece, and the efficient height is effective.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, one end of cutter hub 1 is a guide ring 5, the guide ring external diameter is consistent with workpiece 2 diameter of bores, the guide ring inboard is provided with along circumferential six uniform blades 6, the edge of a knife of each blade is positioned on the same taper seat with the guide ring coaxial line, cone tip is towards guide ring one end, become the handle of a knife 3 of the little matched in clearance of H8/f8 to be hollow shaft with the cutter hub endoporus, the one end is provided with transverse handle 4, the other end has " L " shape open slot 8, groove width is consistent with circular radial pin 7 diameters in being located at the cutter hub endoporus, and above-mentioned each blade and cutter hub are integrally welded.
