Description

Tool for machining fan-shaped cutter

Technical Field

The utility model relates to the field of machining, especially, relate to a frock for processing fan-shaped cutter.

Background

As shown in fig. 1, due to the special shape of the sector cutter, the machining of the outer circle and the cutting edge of the sector cutter needs to be performed on a special machine tool, and because the required amount is not very large, a special machine tool is specially configured to cause a huge burden of production investment to enterprises, which is not favorable for resource optimization configuration and a production mode of energy conservation and emission reduction.

Disclosure of Invention

To the problem, the utility model discloses a frock for processing fan-shaped cutter, this frock can break the cutter and to the requirement restriction of lathe, only uses common cylindrical grinder to process fan-shaped cutter.

The utility model provides a frock for processing fan-shaped cutter, includes the cutter fixed disk, the up end outside of cutter fixed disk is provided with fixed recess, fixed recess and the coaxial setting of cutter fixed disk, evenly be provided with multiunit shop bolt along circumference in the fixed recess, recess upper portion is provided with the preforming.

Preferably, the cross section of the tablet is L-shaped.

Preferably, the inner diameter of the fixing groove is larger than the combined inner diameter of the fan-shaped cutters.

Preferably, the pressing sheet is connected with the cutter fixing disc through a butterfly nut.

Preferably, the outer diameter of the cutter holder disk is 5mm smaller than the combined outer diameter of the fan-shaped cutters.

Preferably, the center of the cutter fixing disc is provided with a through hole.

The utility model has the advantages that:

(1) by adopting the tool, a plurality of fan-shaped cutters can be simultaneously machined on a common grinding machine, one set of tool realizes the technical effects of machining an excircle and a cutting edge, the input cost of a machining machine tool is saved, and the machining efficiency is improved.

(2) The inner diameter of the groove is larger than the combined inner diameter of the fan-shaped cutter, so that the installation is convenient.

(3) The butterfly nut is convenient for hand tightening, and operation time is saved.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a view of a fan blade configuration;

FIG. 2 is a front view of the fan-shaped cutter after assembly with the tooling;

FIG. 3 is an assembled view during the machining of the cutting edge;

FIG. 4 is an assembled view when processing an outer circle;

1. the cutting tool comprises a cutting tool fixing disc, 2, a pressing sheet, 3, a butterfly nut, 4, a fan-shaped cutting tool and 5 and a positioning pin.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it should be understood that the terms "inside", "outside", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

As shown in fig. 2-4, the utility model discloses a frock for processing fan-shaped cutter, this frock includes cutter fixed disk 1, and the center of cutter fixed disk is provided with the through-hole, is convenient for be connected with the lathe. The up end outside of cutter fixed disk is provided with fixed recess, and fixed recess and the coaxial setting of cutter fixed disk, 4 circumference of fan-shaped cutter are installed side by side in the recess, and this fixed recess's internal diameter is greater than the combination internal diameter of fan-shaped cutter, so set up the installation of can being convenient for, prevent to arouse between the adjacent cutter and interfere. The outer diameter of the cutter fixing disc is 5mm smaller than the combined outer diameter of the fan-shaped cutter, so that the outer circle of the fan-shaped cutter can be conveniently machined. For convenient location, evenly be provided with multiunit shop bolt 5 along circumference in the fixed recess, every group is two, sets up with the mounting hole cooperation of fan-shaped cutter. After the fan-shaped cutter 4 is matched with the fixed groove and installed in place, the cutter is pressed by the pressing sheet 2 at the upper part, and the pressing sheet and the fixed disc 1 are fixed by the butterfly nut 3. The butterfly nut is convenient for tighten by hand, and is convenient and quick to detach.

During machining, the sector cutter hole is inserted into a fixing pin on the fixing disc, then the butterfly nut is manually screwed to compress, the angle of the grinding head of the grinding machine is adjusted according to the machined part to machine the corresponding part, and the hard alloy sector blade can be simply and quickly ground in an excircle mode and can be ground at any angle (within the machining range of the machine tool) in a blade changing mode.

In order to realize that a set of tool can simultaneously carry out two processing procedures of grinding the excircle and opening the edge on the fan-shaped cutter, the cross section of the pressing sheet is set to be L-shaped, and the single fan-shaped cutter is pressed towards one side of the fixed groove by the convex side of the L-shaped pressing sheet during edge opening; when the excircle is ground, a plurality of fan-shaped cutters can be installed in the fixed groove in an overlapping mode, and then the protruding side of the L-shaped pressing sheet faces the outer side to press the fan-shaped cutters.

The tool can break the requirement limit of the tool on a machine tool, and the fan-shaped tool can be machined only by using a common cylindrical grinding machine.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
