CN2673542Y - Composite round inverted angle knife for processing bearing jacket ring - Google Patents

Abstract

The utility model belongs to a cutter for machine, a composite round inverted angle knife for processing bearing jacket ring provided is mainly composed of a knife bar (3) and a knife blade (4). The knife blade (4) is fixed on the anterior part of the knife bar (3), and two cutting edges respectively used for processing the inner round angle and the outer round angle of the bearing jacket ring are arranged on the knife blade. As the utility model has two cutting edges which are respectively used for processing the inner round angle and the outer round angle of the bearing jacket ring, so the cutting edges can replace the function of the existing two round angle knives. Thereby, the number of the knife bar is relatively cut down, the material of the knife bar is saved, and the cost is reduced. In addition, the frequency of the cutter clamping and the adjustment is cut down when in the processing time, the auxiliary time is cut down, and the production efficiency is raised.

Description

The machining bearing lasso is with making up the rounded corner cutter

Affiliated technical field

The utility model belongs to the machined cutter, relates generally to a kind of machining bearing lasso with making up the rounded corner cutter.

Background technology

In mechanical industry, almost each part all needs chamfering.For bearing industry, its main processing parts is a lasso, and the inside and outside circle chamfering on the lasso need be through twice processing successively.Once be the car chamfering before the ring quenching, another time is to remove the correction chamfering that oxide skin is carried out for improving the bearing presentation quality behind the ring quenching.In process, owing to have only a cutting edge on the rounded corner cutter of processing, traditional chamfering method generally is in vertical and horizontal direction two rounded corner cuttves to be installed simultaneously on knife rest.As shown in Figure 1, utilize level to be installed in the bull nose R that rounded corner cutter 1 on the knife rest 7 processes bearing ring 8 earlier, follow rest 7 utilizes the rounded corner cutter of vertically installing 2 to process the filleted corner r of bearing ring 8 to accompanying drawing 2 positions then.Like this, lasso of every processing just needs two rounded corner cuttves are installed, and knife rest 2 position strokes are bigger from accompanying drawing 1 to accompanying drawing, cause production efficiency low.

Summary of the invention

The purpose of this utility model provides a kind of machining bearing lasso of enhancing productivity with making up the rounded corner cutter.

The purpose of this utility model can adopt following technical scheme to realize: it mainly is made up of knife bar and blade, and blade is fixed on the front end of knife bar, has two cutting edges that are respectively applied for the inside and outside fillet of machining bearing lasso on it.

Described blade can constitute by being respectively applied for two blades of the inside and outside fillet of machining bearing lasso, and it is separately fixed at the both sides of knife bar front end.

As from the foregoing, the utlity model has two cutting edges, be respectively applied for the processing of the inside and outside fillet of bearing ring, can replace the function of existing two fillet knifes, thereby correspondingly reduced the quantity of knife bar, saved the knife bar material, reduced cost.In addition, add man-hour, also reduced the cutter clamping times and adjusted number of times, reduced non-cutting time, improved production efficiency.

The specific embodiment

In conjunction with the accompanying drawings, specific embodiment of the utility model is described:

Shown in Fig. 3,4,5, the utility model mainly is made of knife bar, blade 4, and blade 4 is fixed on the front end of knife bar 3, has two cutting edges on it, is respectively outer rounded corner cutting edge 5 and interior rounded corner cutting edge 6.Blade 4 also can be made of two blades, is separately fixed at the both sides of knife bar 3 front ends, constitutes two rounded corner cutting edges.

Shown in Fig. 6,7, cutter vertically is fixed on the knife rest 7, utilize outer rounded corner cutting edge 5 to process the bull nose R of bearing ring earlier, follow rest 7 then, and rounded corner cutting edge 6 processes the filleted corner r of bearing ring in utilizing.

Claims (2)

1, a kind of machining bearing lasso mainly is made up of knife bar (3) and blade (4) with combination rounded corner cutter, and it is characterized in that: blade (4) is fixed on the front end of knife bar (3), has two cutting edges that are respectively applied for the inside and outside fillet of machining bearing lasso on it.

2, machining bearing lasso according to claim 1 is with making up the rounded corner cutter, and it is characterized in that: described blade (4) can constitute by being respectively applied for two blades of the inside and outside fillet of machining bearing lasso, and it is separately fixed at the both sides of knife bar (3) front end.
