Abstract
The utility model provides a bidirectional circular hole chamfering tool. The bidirectional circular hole chamfering tool comprises a tool handle, a tool bar and a tool head, wherein the upper part of the tool handle is connected with a main shaft of a machine tool, the lower end of the tool handle is connected with the tool bar, and the front end of the tool bar is the tool head; forward tool edges are distributed at the lower end of the tool head, reverse tool edges are distributed at the upper end of the tool head, the tool edges are symmetrically distributed along the axis of the tool head, and the included angle alpha between the tool edges and the tool body is consistent with the chamfering angle of a circular hole to be machined. According to the bidirectional circular hole chamfering tool, the tool bar and the tool head are in an integrated structure, the two groups of tool edges for forward and reverse chamfering are distributed on the tool head along the axial direction, the forward tool edges on the front end of the tool head are used for forwardly interpolating chamfers, after the forward chambering is finished, the tool advances along the axis of the hole and the reverse tool edges on the back end of the tool head are used for reversely interpolating chamfers. The bidirectional circular hole chamfering tool has the advantages that the forward and reverse chamfering of the circular hole can be finished by adopting one tool, working procedure contents are concentrated, the machining efficiency is improved, an angle head tool is not used, and the tool cost and the maintenance cost of a production line are reduced.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of chamfering tool.
Background technology
During the present reverse chamfering of Cutter Body Processing with Machining Center cylinder body actuating motor installing hole, normally according to the requirement of product chamfering, the chamfering tool of selection coupling adds joins the reverse chamfer machining of angle head.The problem that this processing mode exists is: the two-way chamfering of actuating motor installing hole need to adopt subland drill and angle head rose reamer to process in two steps, has increased process time and non-cutting time, angle head cutter somewhat expensive, and the production line operation expense is high.
Chinese patent literature CN201950256U discloses a kind of circular-hole chamfering tool for machine tooling center, and it is provided with cutter hub and blade, and blade is arranged two groups at the cutter hub axial plane, can carry out chamfering to the circular hole two sides, but it can't carry out chamfering to the small-bore circular hole.
Chinese patent literature CN201313182Y discloses a kind of interior chamfering combination rose reamer, and it is provided with knife bar and two cutter heads, and a cutter head is arranged in the middle part of knife bar, and a cutter head is arranged in the knife bar front end, can be connected with knife bar or disconnect, and can carry out chamfering to cast spare.But it is unsuitable for machining center box parts chamfering.
Summary of the invention
The purpose of this utility model is that the existing working (machining) efficiency of the above-mentioned existing processing cylinder body actuating motor installing hole chamfering technology of solution is low, cost of charp tool high-technology problem, the two-way chamfering tool of the circular hole that provides a kind of machining center to use, make the cost of charp tool reduce, the operation content is concentrated, and working (machining) efficiency improves.
The technical solution of the utility model is as follows:
The two-way chamfering tool of a kind of circular hole comprises handle of a knife, knife bar and cutter head, and handle of a knife 1 top is connected with machine tool chief axis, and the lower end connects knife bar, and the knife bar front end is cutter head.Described cutter head lower end is distributed with the forward blade, and the upper end is distributed with reverse blade, and blade is symmetrical along the cutter head axis, and blade is consistent with the chamfer angle of cutter hub axis angle α and required processing circular hole.
This two-way chamfering tool adopts knife bar, cutter head overall structure, cutter head distributes vertically two groups and is used for the blades of forward and reverse chamfering, cutter head front end forward blade is used for forward interpolation chamfering, complete the forward chamfering after cutter along the feeding of axle center, hole, the reverse blade in cutter head rear end is used for reverse interpolation chamfering.
As preferably, the blade of cutter head is symmetrical along axis.
As preferably, described chamfering tool adopts carbide alloy to make and forms.
Forward and reverse chamfering of circular hole has been completed cutter in the utility model employing one, and the operation content is concentrated, and has improved working (machining) efficiency; Avoid employing angle head cutter, reduced the cost of charp tool and production line maintenance cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view in the A-A cross section of Fig. 1.
Be labeled as in accompanying drawing: 1. handle of a knife, 2. knife bar, 3. cutter head, 4. forward blade, 5. reverse blade.
The specific embodiment
Below contrast Fig. 1 and Fig. 2, the utility model be described further:
This cutter adopts carbide alloy to make and forms, and comprises handle of a knife 1, and handle of a knife top is connected with machine tool chief axis, lower end connection knife bar, and the knife bar front end is cutter head.The cutter head front-end and back-end are distributed with forward blade and reverse blade, and they are symmetrical along the cutter hub axis, and blade is consistent with the circular hole chamfer angle of cutter hub axis angle α and required processing.
During processing circular hole chamfering, select suitable tool dimension and knife edge angular according to workpiece circular hole aperture and chamfer dimesion, blade can be processed the chamfering of different depth by the circular interpolation program, after completing the forward chamfering, cutter is along the round hole axial feeding, complete the reverse chamfering of workpiece by reverse blade interpolation, realize that a cutter completes the forward and reverse chamfering of workpiece.
