Description

A kind of annular tongue-and-groove processing presetting cutter method

Technical field

The present invention relates to a kind of machining process, select when processing annular tongue-and-groove knife point more particularly to a kind of Method.

Background technique

In aviation industry, with the promotion of designed capacity and manufacturing capacity, the integration degree of engine component is also got over Come higher, Element Design tends to entirety, light weight, accurate development, and moulding surface structure also becomes increasingly complex.This model disc type work is High-temperature alloy material belongs to one of easily-deformable material, and the complex-curved development such as thin-walled, more space type faces are also tended in structure.It is high Temperature alloy material hinge is hard, exists allow knife in process, annular tongue-and-groove required precision is higher, not easy to be processed to arrive qualified size.

During processing annular groove, part is easy to appear deformation, causes annular tongue-and-groove precision that cannot reach standard, so such as The problem being not easily overcome is deformed into during the annular tongue-and-groove Vehicle Processing of what reduction.

The shape of annular tongue-and-groove such as attached drawing, middle part most narrow dimension only have width 5+0.075mm, and lower part the widest part size has 8.28 +0.2mm.Groove structure is complicated, and middle part is narrow, and universal cutter is caused to cannot be introduced into, so processing one cannot complete knife, it can only Application specific annular groove knife by processing step by step.

Summary of the invention

The technical problem to be solved in the present invention: processing dimension is caused not conform to because material deforms for when processing annular tongue-and-groove The problem of lattice, provide a kind of multipair knife point to knife mode.

Technical solution of the present invention:

A kind of annular tongue-and-groove processing presetting cutter method: there be one of outer circle fluting in part side to be processed, and middle part longitudinally has one Road annular tongue-and-groove, the exposed straight mouth for selecting the outer circle of side to slot first is as first longitudinal direction to knife point, the end face of outer circle fluting It is vertical using the right side of annular tongue-and-groove bottom end face or left side as second after processing outer circle fluting as first laterally to knife point To knife point, using the right side at the most narrow place of annular tongue-and-groove or left side as second laterally to knife point, finally with annular tongue-and-groove bottom The left or right side of end surface is longitudinal to knife point as third, using the left side at the most narrow place of annular tongue-and-groove or right side as third Laterally to knife point.

The tool nose used when for the first time to knife is vertical.

The cutter that the tool nose used when for the second time and third time is to knife is stretched out from side, and used when processing twice Point of a knife is contrary.

The invention has the advantages that:

Normal Vehicle Processing only with one to knife point to knife, do not account in processing part deformation to the shadow next processed It rings, this patent avoids influence of the part in a disguised form to next processing, ensure that the essence of size by the different selections to knife point Degree.

This presetting cutter method is suitable for annular tongue-and-groove Vehicle Processing on all types of disk parts of aeroplane engine, can guarantee tongue-and-groove processing essence The technical requirements such as degree, symmetry, position degree solve and not can guarantee asking for annular tongue-and-groove precision during machining Topic reduces the influence that annular tongue-and-groove two sides are processed in deformation, is successfully applied to annular groove disk-like accessory.

Detailed description of the invention:

Fig. 1 is the position view of first pair of knife point.

Fig. 2 is the structural schematic diagram of straight knife tool.

Fig. 3 is to have the schematic diagram just slotted using straight knife.

Fig. 4 is the position view of second pair of knife point.

Fig. 5 is the structural schematic diagram of turning cutting tool on the right side of annular groove.

Fig. 6 is position view of the third to knife point.

Fig. 7 is the structural schematic diagram of turning cutting tool on the left of annular groove.

Fig. 8 is three overall schematics to knife point on part.

Specific embodiment:

Embodiment: being longitudinally X in the present embodiment to lateral is Z-direction, is the edge of a knife when to knife to knife, i.e. Z=0.

1. first straight knife tool (T0707 knife) to knife point: for X to knife point, Fig. 1 show straight mouth outer circle.Z-direction is to knife Point: as shown in Figure 1 for part base position end face.Fig. 2 is cutter schematic diagram.First selection to knife point: as shown in Figure 1, Because necking tool is just to slot (i.e. normal cylindrical fluting)

Reason:

Normal precision of just slotting is ensured that with precision of the end face to knife.So this selects knife point exposed straight mouth As X to knife point, end face as shown in the figure is as Z-direction to knife point.(Fig. 1)

2. on the right side of annular groove turning cutting tool to knife point (T1010 is to knife point):

(Fig. 3) is again to T1010 knife after first just being slotted using T0707 knife.

The X of T1010 is to tool setting position (Fig. 4), because the position can directly be measured by vernier caliper, which is ring Trench bottom position can be ignored with the position deflection of annular groove.

The Z-direction tool setting position of T1010: point of a knife as shown in the figure is fitted on the right of straight trough knife point, is Z-direction on the right of setting straight trough Zero point.(Fig. 4)

Because being that a upper work step is process (Fig. 3) on the right of straight trough, can directly be neglected with the deflection of annular groove on the right of straight trough Slightly disregard.

Reason: this part thin-wall part, straight mouth exists with annular groove diagram X position deforms inconsistent, deflection at the straight mouth in outside Probably within 0.20.So this is directly to avoid outer straight mouth to knife point in annular groove inner plane (i.e. diagram X position) to knife point With the deflection of annular groove interior diameter.It is to knife point that Z-direction, which directly selects the end face just slotted,.

3. on the left of annular groove turning cutting tool to knife point (T0909 is to knife point):

(Fig. 3) is again to T0909 knife, the cutter structure of T0909 such as Fig. 7 after first just being slotted using T0707 knife

Annular groove knife tool setting position is the position of X as shown in Figure 6.Because the position can directly be measured by vernier caliper, The position is annular groove bottom position, be can be ignored with the position deflection of annular groove.

The Z-direction tool setting position of T0909: point of a knife as shown in the figure is fitted in the straight trough left side to knife point, and the setting straight trough left side is Z-direction Zero point.

Because the straight trough left side is that a upper work step is process (Fig. 3), the straight trough left side can directly be neglected with the deflection of annular groove Slightly disregard.
