Abstract
The utility model provides an utensil is assisted in magnetic drill processing which uses the holding surface to be supporting, with binding face and navigation key piece location, alignment, adjusts the position simultaneously, and the machining precision expects much and the hole of the unable processing of numerical control device. Design center position and product design two measure -alike holes on the structure, this hole is used for installing the interchangeable uide bushing. Magnetic drill adsorbs on the face, through the uide bushing direction, carries out the processing in hole. The utility model discloses the position degree and the straightness that hangs down in the hole of magnetic drill processing have been guaranteed, the mechanism design of interchangeable uide bushing has increased the life of structure, reduction in production cost.
Description
Technical field
This utility model is related to a kind of magnetic drill and processes thermal power generation steam turbine low-pressure outer shell lower half key slot ends hole
Frock, belongs to machining cutting tool special for processing frock.
Background technology
For the thermal power generation processing in steam turbine low-pressure outer shell lower half key slot ends hole, also do not occur in prior art specially
With frock to more accurately being processed herein, and lack special tooling often result in numerical control device cannot process, magnetic drill
Adsorption area is little, the positional precision in hole and perpendicularity can not guarantee, causing cannot the result such as Repair gene.
But adopt rational cutter frock, our course of processing can be simplified, ensure design requirement simultaneously, thus greatly
The big production efficiency improving machine-building, improve product quality, saving manufacturing time, reduction production cost, therefore design a kind of
The frock being exclusively used in magnetic drill processing thermal power generation steam turbine low-pressure outer shell lower half key slot ends hole is very important.
Content of the invention
In view of the defect of prior art, this utility model provides a kind of magnetic drill processing accessory it is therefore intended that assisting magnetic
Bore the processing auxiliary mould in the hole of processing dedicated location.This utility model breaches existing Traditional Thinking and structure, thus will
Magnetic drill processes the position degree in hole and Perpendicular Problems solve, and improves working (machining) efficiency it is ensured that qualification rate, reduces human cost
And manufacturing cost.
For achieving the above object, a kind of magnetic drill processes accessory, it include magnetic drill adsorption plate, limited block, positioning key block,
Fairlead installing hole and fairlead；The side upper end setting limited block that magnetic drill adsorption plate is contacted with the surface of workpiece to be processed,
On limited block lower surface, setting positioning key block, magnetic drill adsorption plate arranges some fairlead installing holes, and in the hole installed by fairlead
Fairlead is installed.It is the cooperation of unthreaded hole slight interference between fairlead installing hole and fairlead, be bumped into installation.
Preferably magnetic drill adsorption plate is U-shaped, and the inner concave of U-shaped magnetic drill adsorption plate is supporting surface.
This utility model with supporting surface for support, simultaneously with the binding face on limited block and positioning key block positioning, centering,
Adjust state.Hole at two is designed on structure, this hole is used for installing interchangeable fairlead.Magnetic drill is adsorbed in plate face, leads to
Cross fairlead guiding, carry out the processing in hole；By pilot hole, carry out the processing operation of magnetic drill.Using interchangeable fairlead, guide
The material of set is wear-resisting, long service life；Change without whole after abrasion, only need to change fairlead.The present invention is especially suitable for it is fiery
Power power generation turbine lp outer casing lower half key slot ends hole machined.
The beneficial effects of the utility model：Apply in magnetic drill in the course of processing in end face silk hole, can process once to become
Product, it is to avoid numerical control device cannot be processed, magnetic drill adsorption area is little, hole positional precision and perpendicularity can not guarantee, cause
Cannot the result such as Repair gene, thus magnetic drill is processed the position degree in hole and Perpendicular Problems solve, improve processing effect
Rate, it is ensured that qualification rate, reduces human cost and manufacturing cost.

Specific embodiment
As accompanying drawing, this utility model, to paste dough-making powder 5 for supporting, is positioned with positioning key block 3, centering simultaneously, adjusts state.
Magnetic drill is adsorbed in magnetic drill adsorption plate 1 plate face, is guided by fairlead, carries out the processing in hole.
A kind of magnetic drill processes accessory, and it includes magnetic drill adsorption plate 1, limited block 7, positioning key block 3, fairlead installing hole
2 and fairlead 6；The side upper end setting limited block 7 that magnetic drill adsorption plate 1 is contacted with the surface of workpiece to be processed, under limited block 7
Setting positioning key block 3 on surface, magnetic drill adsorption plate 1 arranges some fairlead installing holes 2, installs in fairlead installing hole 2
Fairlead 6.
Preferably magnetic drill adsorption plate 1 is U-shaped, and the inner concave of U-shaped magnetic drill adsorption plate 1 is supporting surface 5.
Accessory is processed due to magnetic drill and requires must assure that stationarity and the machining accuracy of processing, design must assure that it is strong
Degree and rigidity, therefore structure design is durable, and weight is also heavier, but the weight of itself is just sufficient for processing and wants
Ask, be fixed operation without especially accessory being processed to magnetic drill.Fairlead installing hole designs strictly with the depth of parallelism of binding face,
So as to ensure the perpendicularity in hole and workpiece on request, this frock fully achieves design requirement through practical operation.
The beneficial effect of the present embodiment：Magnetic drill adds to silk hole at thermal power generation steam turbine low-pressure outer shell lower half keyway
Work impact greatly, to processing one-pass finished herein, it is to avoid in the past herein numerical control device cannot process, magnetic drill adsorption area
Little, hole positional precision and perpendicularity can not guarantee, causing cannot the result such as Repair gene.
