Abstract
The utility model relates to a combined boring tool which comprises a tool bit and boring tool blades. Three circumferential evenly arranged tool bores are axially formed on the tool bit; two threaded through holes are respectively and radially formed on the tool bit in the positions corresponding to each tool bore; each threaded through hole is respectively communicated with the corresponding tool bore; the boring tool blades are mounted in the corresponding tool bores and fixed through the threaded through holes via screws; the three boring tool blades on the tool bit can be used for simultaneously processing corresponding chamfered surfaces; and the tool bit is not required to be replaced at midway. Therefore, the machining accuracy of parts is guaranteed, and the production efficiency is improved.
Description
Technical field:
The utility model relates to a kind of auxiliary cutter of processing spiracle line on the motorcycle engine cylinder cap, particularly a kind of combination boring cutter.
Background technology:
In the prior art, spiracle line has three continuous different angles on the motorcycle engine cylinder cap, the fillet surface of different depth, these three fillet surfaces are directly connected to the quality of engine quality, thereby its shape, position and dimension precision requirement are all very high, common process equipment is a lathe, special fixture and three corresponding cutter heads, processing method is earlier with workpiece clamping once on special fixture, three cutter heads that change the outfit respectively then machine it, wherein each cutter head is processed a corresponding fillet surface, the weak point of this kind process equipment and method is: need the frequent cutter head that changes the outfit, rigging error appears in cutter head easily in the process of changing the outfit, and then directly influence the machining accuracy of part, cause product quality to be not easy control, in addition, the frequent cutter head that changes the outfit has also directly reduced production efficiency.
The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of combination boring cutter that can be simultaneously three fillet surfaces of spiracle line on the cylinder cap be processed at one time is provided.
A kind of combination boring cutter that provides according to the utility model, comprise cutter head, boring cutter sheet, described cutter head axially on have three tool bores, the footpath that circumferentially evenly are provided with and upwards all have two tapped through holes corresponding to each tool bore place, each tapped through hole all communicates with corresponding tool bore, the boring cutter sheet is installed in the corresponding tool bore, and is fixed by tapped through hole by screw.
In addition, the utility model also has following attached technical characterictic:
Described cutter head front end is provided with the axis of guide, the place, axle center has the cutter shaft hole that connects cutter shaft.
A kind of combination boring cutter that provides according to the utility model with respect to the advantage of prior art is:
In the utility model, cutter head axially on have three tool bores that circumferentially evenly are provided with, corresponding boring cutter sheet all is installed in each tool bore,, is regulated and set the axial location and the blade angle of each boring cutter sheet respectively according to the position and the size of three fillet surfaces of spiracle line on the cylinder cap, in process, three boring cutter sheets can process corresponding fillet surface simultaneously on this cutter head, and the centre does not need the cutter head that changes the outfit, thereby, guarantee the machining accuracy of part, also improved production efficiency.
Put description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of left apparent direction of the present utility model;
Fig. 2 is the sectional structure schematic diagram of A-A among Fig. 1;
Fig. 3 is the structural representation of right apparent direction of the present utility model.
The specific embodiment:
With reference to Fig. 1, Fig. 2, a kind of combination boring cutter that provides according to the utility model, comprise cutter head 1, boring cutter sheet 2, cutter head 1 axially on have three tool bores 11 that circumferentially evenly are provided with, the footpath upwards all has two tapped through holes 12 corresponding to each tool bore 11 place, each tapped through hole 12 all communicates with corresponding tool bore 11, boring cutter sheet 2 is installed in the corresponding tool bore 11, and pass through tapped through hole 12 by screw and fixed, position and size according to three fillet surfaces of spiracle line on the cylinder cap, before the processing, regulate and set the axial location and the blade angle of each boring cutter sheet 2 respectively, in process, three 2 of boring cutters can process corresponding fillet surface simultaneously on this cutter head 1, the centre does not need the cutter head that changes the outfit, thereby, guaranteed the machining accuracy of part, also improved production efficiency, cutter head 1 front end is provided with the axis of guide 13, the place, axle center has the cutter shaft hole 14 that connects cutter shaft.
