Description
Technical field
The utility model relates to the clamping toolings of a kind of long hollow shaft class inner bore of part and outer circles processing.
Background technique
Long hollow shaft class part involved in the utility model is a kind of main component for carrying out hydrogen gas gun test, is to carry out
The core part of ultra-high-speed test device, inner hole is more demanding with outer circles, result of the Accuracy of finish to test
Play key effect.Traditional long hollow shaft class part concentricity processing method be by inner hole after processing is completed, both ends difference
With two center plugs, center plug one end processes a straight section and long hollow shaft class inner bore of part cooperates, another outer end face processing
One with the centre bore of lathe centre taper fit, through two top clampings on lathe, since the straight section of center plug is in
Have coaxiality error when heart hole machined, when centre bore and lathe top cone match can also generate error, often result in final
The concentricity of product is difficult to ensure, influences processing quality.
Summary of the invention
The purpose of this utility model is to be directed to above-mentioned status, it is desirable to provide one kind is not required to clamping centering；Long hollow shaft class zero
Part Excircle machining stability is good, the clamping tooling of the high long hollow shaft class part concentricity processing of concentricity.
The utility model aim implementation is the clamping tooling of long hollow shaft class part concentricity processing, by left tooling
And right tooling is constituted；
The left tooling end is the conical surface cooperated with machine chuck center hole, is had and machine chuck and workpiece on the inside of the conical surface
The boss that end face matches, the 1/20 of the left a length of long hollow shaft length of tooling；The internal diameter of left tooling outer diameter and long hollow shaft inner hole
Fit clearance is 0.005mm；
The right tooling end is the conical surface that the cooperation of center sleeve bore is filled with tailstock tool, has flange, flange on the inside of the conical surface
On have the hole matched with tailstock tool screw hole, be bolted；The internal diameter of right tooling outer diameter and long hollow shaft inner hole cooperates
Gap is 0.005mm.
The processing tool of the utility model alternative center plug and top cooperation solves long hollow shaft class part concentricity
The problem of processing.
Long hollow shaft class inner bore of part completes the process, and using the utility model, the conical surface of left tooling is mounted in lathe chuck top
In pointed orifice, the conical surface of right tooling uses bolt between the hole on flange and tailstock tool screw hole in tailstock tool center sleeve bore
It is fixedly connected.Directly using longaxones parts inner hole precision as the benchmark of Excircle machining, long hollow shaft class part is processed.
The utility model solves mismatch error when plug outer circle and hollow shaft inner hole clamping, when reducing clamping centering
Between；Long hollow shaft class part Excircle machining stability is good, and concentricity is high.

Fig. 2 is the left tooling usage state diagram of the utility model；
Fig. 3 is the right tooling usage state diagram of the utility model；
Fig. 4 is the left tool structure schematic diagram of the utility model；
Fig. 5 is the right tool structure schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings.
Referring to Fig.1, the utility model is made of left tooling 2 and right tooling 4.
Referring to Fig. 2,4, left tooling end is the conical surface cooperated with 1 center hole of machine chuck, is had and lathe card on the inside of the conical surface
The boss that disk and major axis parts hollow end face match.The 1/20 of the left a length of long hollow shaft length of tooling；Left tooling and long hollow shaft
The outer diameter of inner hole is surveyed size by the diameter of bore of long hollow shaft, is ground, left tooling outer diameter compares long hollow shaft
The small 0.005mm of the internal diameter of part；The internal diameter fit clearance of i.e. left tooling outer diameter and major axis parts hollow is 0.005mm.
Referring to Fig. 3,5, right tooling end is the conical surface cooperated with 5 center sleeve bore of tailstock tool, has flange on the inside of the conical surface,
There is the screw hole matched with tailstock tool screw hole on flange.The 1/20 of the right a length of long hollow shaft length of tooling；Right tooling with it is hollow
The outer diameter of long axis inner hole is surveyed size by the diameter of bore of long hollow shaft, is ground, right tooling outer diameter is than hollow
The small 0.005mm of the internal diameter of long shaft part；The internal diameter fit clearance of i.e. right tooling outer diameter and major axis parts hollow is 0.005mm.
1/20, fit clearance 0.005mm of the left and right a length of long hollow shaft length of tooling, ensure that left and right tooling with it is hollow
Long axis inner hole is close, keeps long hollow shaft class part Excircle machining stability good, and concentricity is high.
Long hollow shaft class inner bore of part completes the process, and when using the utility model, referring to Fig.1, the conical surface of left tooling is mounted in
In lathe chuck center hole, hole and tailstock tool spiral shell of the conical surface of right tooling in tailstock tool center sleeve bore, on flange
It is fixedly connected between hole with bolt, processes long hollow shaft class part.
By taking the processing of certain long hollow shaft class part as an example, which is 5000mm, and diameter of bore isTolerance
0.025mm, outside diameterOuter circle and coaxiality of inner hole are 0.025mm.Since the hollow shaft length is longer, inner hole precision,
Internal-external circle concentricity is more demanding, and processing is more difficult.
The applicant's selection carries out hollow shaft Excircle machining on CK61120 numerically controlled lathe.The left a length of 250mm of tooling, outside
The internal diameter fit clearance of diameter and long hollow shaft is 0.005mm；The right a length of 250mm of tooling；Outer diameter and the internal diameter of long hollow shaft cooperate
Gap is 0.005mm.
When using the utility model, for the conical surface of left tooling in lathe chuck center hole, the conical surface of right tooling is mounted in machine
In tailstock seat center sleeve bore, the hole on flange is fixedly connected between tailstock tool screw hole with bolt, directly by longaxones parts
Benchmark of the inner hole precision as Excircle machining does not need to carry out centering again, can carry out long hollow shaft outer circle finishing.
The utility model reduces clamping alignment time, and long hollow shaft class part Excircle machining stability is good, and concentricity is high.
