Have a knife rest, the knife rest is equipped with cutter, the pedestal side be equipped with the one-to-one sensor of item that works, it is above-described
Bearing race blank cutter device not only ensure that cutting accuracy, but also production efficiency is also very high.
But the cutter used is only used for cutting bearing race and detach, effect is single.
Utility model content
The utility model aim be intended to provide it is a kind of it is simple and reasonable, effectively raw material steel pipe can be carried out
Cutting detaches and can carry out chamfered to the outer rim of bearing race blank, save the bearing race blank cutting of subsequent processing operations
Equipment.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of bearing race blank cutting equipment, including the first cutter, the second cutter, first cutter is cuboid,
The first cutter upper surface is radially provided with the card slot for fixing the second cutter, and second cutter is fixed at card
In slot, the second cutter left end extends outside card slot to the left；The first cutter left end top surface extends to form first and cuts to the left
Portion is cut, first cutting portion sets there are two and is symmetrically distributed in card slot both sides, and the second cutter left end top surface is prolonged to the left
It stretches to form the second cutting portion.
It further limits, the card slot two side is equipped with limiting fin, second cutter and limiting fin corresponding position
Limiting groove is provided with, the limiting groove is clamped with limiting fin cooperation.
It further limits, card slot upper surface side center of keeping right is provided with step, and the step upper surface is provided with several
Evenly distributed bar shaped double wedge, the second cutter right end top are connected by shaft by turnover panel, and the turnover panel lower surface is provided with
Bar shaped recess corresponding with bar shaped double wedge, the bar shaped recess are clamped with the cooperation of bar shaped double wedge.
Further limit, it is described second cutting end surface be plane, it is described first cutting end surface on the inside of extend outwardly with
Outside forms arcwall face or inclined-plane.
It further limits, the second cutter thickness 1.5mm to 2mm.
Using the utility model of above-mentioned technical proposal, after the first cutter and the cooperation of the second cutting knife set, connect with knife rest
It connects, and the steel pipe of rotation is cut, realize and bearing race blank is cut；Outside two the first cutting portions of the first cutter left end
Language card slot both sides should be then positioned at the both sides of the second cutter, and the cutting portion of the second cutter is used as and the steel pipe that breaks, the first cutter
Cutting portion can cut notching edge while the second cutter pipe cutting for being cut to steel pipe notching edge
Chamfering is cut, simplifies subsequent processing operations, saves production cost；The limiting fin of card slot both sides and the limiting of the second cutter both sides
Groove cooperation clamping enables the slip of the second cutter income also to limit it while be conveniently adjusted cutting portion extension elongation
Position prevents it from vertical misalignment occurs, improves its structural stability；Bar shaped double wedge and the bar shaped of turnover panel lower surface setting on step
Groove is mutually clamped, since turnover panel is by being connect at the top of shaft and the second cutter right end, can effectively prevent the second cutter
The radial displacement in card slot further improves its structural stability；Second cutting end surface is that plane can effectively ensure that,
The section of bearing race blank is smooth, first cutting end surface be arcwall face when, can to the stupefied portion's rounded corner of bearing race blank section,
When first cutting end surface is inclined-plane, the stupefied portion bevelling of bearing race blank section can be needed according to different to first
Cutting end surface is polished；Horizontal distance is no more than processing raw material between second cutting end surface and the first cutting end surface
The thickness of steel pipe.
The utility model compared with prior art, it is simple and reasonable, can effectively to raw material steel pipe carry out cutting point
From and can to the outer rim of bearing race blank carry out chamfered, save subsequent processing operations.
