Abstract

The utility model relates to the anti-countersink of a kind of large scale, comprise knife bar, mandrel, tool rest, knife rest plate, blade and correcting wedge, coaxially mandrel is fixedly mounted with in axial one end of knife bar, a tool rest is coaxially fixedly mounted with in mandrel upper end, the radial side extension of this tool rest is shaped with knife rest plate, clamps and be fixed with a correcting wedge between blade and knife rest.The utility model adopts the blade of clamping resetting, adjustable blade is long, blade registration, and blade exchange is convenient and swift, working (machining) efficiency is made to improve 2 times, reduce and even thoroughly eliminate precision adjustment non-cutting time and reprocess the time, reduce anti-countersink sheet consumption costs, reduce anti-ream and process comprehensive manufacturing cost.

Description

The anti-countersink of a kind of large scale
Technical field
The utility model belongs to hydrogenerator and manufactures field, the anti-countersink of especially a kind of large scale.
Background technology
At present, processing anti-ream nut pretension plane conventional tool is that above straight hole boring cutter bar, tool bore internal fixtion is installed high-speed steel side's tool section, tool section needs the technical merit being accumulated processing experience and repetition training for many years by operator self for many years to go out required angle in conjunction with hand grinding, often need to carry out sharpening repeatedly and correction to cutter, surface roughness and Geometrical Tolerance Principle could be met, be difficult to accurate controlled working efficiency, and need after tool damage again to repair sharpening, tool sharpening difficulty, working (machining) efficiency is low, and cost is high.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the anti-countersink of large scale of a kind of installation rational in infrastructure, convenient, highly versatile.
The utility model solves its technical problem and takes following technical scheme to realize:
The anti-countersink of a kind of large scale, it is characterized in that: comprise knife bar, mandrel, tool rest, knife rest plate, blade and correcting wedge, coaxially mandrel is fixedly mounted with in axial one end of knife bar, a tool rest is coaxially fixedly mounted with in mandrel upper end, the radial side extension of this tool rest is shaped with knife rest plate, clamps and be fixed with a correcting wedge between blade and knife rest.
And, described correcting wedge form angle groove with the processing side wall of blade.
And radial both sides are all embedded with the stop screw that is fixed on mandrel upper end in tool rest lower end.
Advantage of the present utility model and good effect are:
1, this cutter increases push type broach voussoir between cutter body and blade, making cutter body, blade, push type broach voussoir form perfect chip space makes the rake face flowing through blade that iron filings can be smooth not result in blockage, and improves the disposable passing rate of processing of anti-ream nut pretension plane.
2, this cutter utilizes angle wedge principle realize the clamping of blade and provide sufficient clamping force, thus makes the work of more allowing blade replacement more convenient.
3, the utility model adopts the blade of clamping resetting, adjustable blade is long, blade registration, and blade exchange is convenient and swift, working (machining) efficiency is made to improve 2 times, reduce and even thoroughly eliminate precision adjustment non-cutting time and reprocess the time, reduce anti-countersink sheet consumption costs, reduce anti-ream and process comprehensive manufacturing cost.

Fig. 2 is the right view of Fig. 1;
Fig. 3 is the top view of Fig. 1;
Fig. 4 is the structural representation of prior art.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The anti-countersink of a kind of large scale, comprise knife bar 7, mandrel 3, tool rest 1, knife rest plate 4, blade 6 and correcting wedge 5, coaxially mandrel is fixedly mounted with in axial one end of knife bar, a tool rest is coaxially fixedly mounted with by centre bolt 2 in mandrel upper end, the radial side extension of this tool rest is shaped with knife rest plate, knife rest plate is used for being fixedly mounted with blade, and the cutting edge of blade extends toward the outer side, and blade cutting edge angle can adopt Standard Machine processing and fabricating.
The present embodiment knife rest plate structure is see shown in accompanying drawing 2, and knife rest plate is by the right angle rack structure being made into integration transverse slat and riser and being formed, for installing fixed blade inside this right angle rack.
In order to can adjustable blade angle, clamp between blade and knife rest and be fixed with a correcting wedge 5, by changing angle, length, the positioning precision of the correcting wedge adjustment blade coordinated, and, correcting wedge form angle groove with the processing side wall of blade, this angle groove can be used as the chip space that processing produces iron filings, avoids clogging, and promotes crudy.
In order to prevent tool rest from rotating, in tool rest lower end, radial both sides are all embedded with the stop screw 8 that is fixed on mandrel upper end.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
