Abstract

The utility model discloses a grinding head for an internal grinder, which is composed of an internal grinder rod (1), alloy oilstones (2) and oilstone slots (3), wherein the front end of the internal grinder rod (1) is in a cylindrical shape, a cylindrical end surface is provided with a plurality of symmetrical oilstone slots (3) along the vertical direction, the number of the oilstone slots (3) is determined according to the demands of processed parts, but at least is not less than two, the alloy oilstones (2) are inserted in the oilstone slots (3), the bottoms of the alloy oilstones (2) are adhered into the oilstone slots (3) of the internal grinder rod (1) at high temperature, the cylindrical end surfaces of various alloy oilstones need to be grinded to guarantee the cylindrical consistence of oilstones. Compared with the prior art, the grinding head for the internal grinder has the advantages of high efficiency, no need of regularly repair for the oilstones during the machining process, reusability, high wear resistance, high stability, low cost, simple structure and the like.

Description

A kind of novel internal grinder bistrique

Technical field

The utility model relates to a kind of instrument, relates in particular to a kind of grinding machine machining tool-bistrique.

Background technology

For a long time, the bistrique that plain grinding machine internal uses is all made by emery wheel mostly, owing to bigger in the loss of grinding process medium plain emery wheel, causes the size instability easily, so trimming wheel repeatedly.Owing to the part material or the size difference of being processed, selected emery wheel is also different simultaneously, and working (machining) efficiency relatively just reduces like this, and dimensional tolerance be cannot say for sure to demonstrate,prove.

Summary of the invention

The technical problem that solves

For addressing the above problem, the utility model provides a kind of new and effective internal grinder bistrique, substitutes the bistrique that common plain grinding machine internal uses.

Technical scheme

The utility model is achieved in that internal grinder usefulness bistrique described in the utility model is by interior mill bar, alloy oilstone and oilstone groove combine, the front end of interior mill bar is cylindrical, longitudinally have the oilstone groove of symmetry at cylindrical end face, the oilstone groove can have several, requirement on processing parts is decided, but minimumly must not be less than 2, the alloy oilstone inserts in the oilstone groove, the bottom of alloy oilstone with bonding agent by high temperature bonding in the oilstone groove of interior mill bar, the end face of each alloy oilstone cylindrical need pass through grinding, to guarantee the unanimity of alloy oilstone cylindrical.

Beneficial effect

The advantage that the utility model bistrique compared with prior art has:

1. the efficient height need not often be repaired oilstone in the process, can use repeatedly;

2. wearability is long, and stability is strong, and cost is low, and is simple in structure;

3. guarantee the quality of product, improve workman's operating efficiency.

1. interior mill bar, 2. alloy oilstone, 3. oilstone grooves among the figure.

The specific embodiment

Below in conjunction with accompanying drawing and concrete enforcement formula novel internal grinder described in the utility model is described in further detail with bistrique:

Embodiment 1:

Fig. 1 and Fig. 2 are internal grinding head overall structure schematic diagram, interior mill bar 1 selects for use the 40cr material to make, the car moulding, mill four long 20mm in bar portion front end face symmetry, wide 10mm, the oilstone groove 3 of dark 1mm, for the bending of anti-stopping bar portion, interior mill bar 1 is through Quenching Treatment, and quenching hardness is HRC35～40, and bar portion cylindrical need finish grind.

Alloy oilstone 2 usefulness brazing powder are added the bonding agent high temperature bonding of brass in four oilstone grooves 3 that interior mill bar 1 mills out.Four oilstone cylindricals need be worn into unanimity, could guarantee the circularity after bonding, so just have been combined into the novel internal grinder bistrique of an integral body.

Claims

1. novel internal grinder bistrique, by interior mill bar, alloy oilstone and oilstone groove combine, it is characterized in that: the front end of interior mill bar is cylindrical, longitudinally have the oilstone groove of symmetry at cylindrical end face, the alloy oilstone inserts in the oilstone groove, the bottom of alloy oilstone with bonding agent by high temperature bonding in the oilstone groove of interior mill bar.

2. a kind of novel internal grinder bistrique according to claim 1, it is characterized in that: the oilstone groove can have several.
