Description
Technical field
The present invention relates to field of machining, the specifically a kind of big overhanging casing method of processing parts of narrow space and folder
Tool.
Background technology
With the raising of engine performance and reliability, the machining accuracy to engine spare part proposes higher want
Ask, for being processed before some crucial sizes and technical conditions under single-piece state, the laggard luggage of single-piece work is matched somebody with somebody, this to add
Work and assembling mode can cause error accumulation, the assembly precision of component be influenceed, in order to reduce the error accumulation shadow of each single-piece work
Component accuracy is rung, Combined machining after assembling is needed for important critical size, to improve component machining accuracy, but combination adds
Man-hour, part working position compares closing, overhangs too big, and processing accessibility is poor, part poor rigidity, and part chatter is tight during processing
Weight, it is impossible to meet assembling and design requirement, accordingly, it would be desirable to explore suitable for the accurate spare part matching requirements of advanced aero engine
Module processing method.
The content of the invention
In order to solve the above technical problems, the purpose of the present invention is to explore a kind of big overhanging of aero-engine, narrow space dress
The ensuring method of distribution assembly critical size and technical conditions, solves component assembling post-processing because the big, system rigidity that overhangs is not enough
Caused processing chatter problem, realizes that single-piece work is processed to component, improves engine pack assembly precision, pass through Auxiliary support
The experiment and optimization of frock, the turnery processing experiment with Auxiliary support frock, the use of cutter cutter holder experiment, are solved processed
Journey chatter problem, completes part processing checking, meets design to engine performance requirement.
Concrete technical scheme is as follows：
A kind of big overhanging casing method of processing parts of narrow space, it is characterised in that：
1) radial direction and axial Auxiliary support are increased in processed corresponding position, in order to solve what can be supported in narrow space
Problem, is supported by the way of upper lower baffle ring clamping elastic rubber ring, the additional deformation of part is not resulted in, to solve component
Processing space is narrow and small the problem of can not support；
2) using the cutter for lengthening handle of a knife；
3) using the tool rest with adjustment knife up, tool rest is connected with lathe cutter saddle, and tool rest clamping cutter flute profile and position pass through
Lathe is calculated knife, using tool rest and lengthening knife combination.
The present invention further discloses a kind of fixture for realizing methods described, including bottom plate, bearing, support ring, guide block, under
Set on support plate, upper cover plate, gland, O-ring, screw, compression spring, the bottom plate on bearing, bearing and support ring be fixedly installed,
Set in support ring and spring eye is set on guide block, guide block, spring is set in the spring eye, and one end of spring is fixed on support ring
On；Set above guide block and lower carrier plate and upper cover plate are set above gland, gland, O-ring, gland are set between upper cover plate and lower carrier plate
Screw is set between lower carrier plate.
It is an advantage of the invention that：The present invention can improve system rigidity, eliminate processing vibration, realize that component is processed, satisfaction is set
Meter and matching requirements, reduce the occurrence of component is overproof, it is ensured that engine is smoothly delivered in time.
Brief description of the drawings
Fig. 1 illustrates for certain component processing request；
Fig. 2 is clamp structure schematic diagram；
Fig. 3 is tool rest schematic diagram.
Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings, and Fig. 1 is certain sub-assembly machining sketch chart, and the component is by component 1, component
2 compositions, combination post-processing size Φ A, technical conditions relative datum A, B bounce 0.05, working position sheet as cantilever design, and
Working position is remote away from upper surface distance, reaches 300mm, and part radially can support position narrow space, it is difficult to support, whole part
Processing technology is poor.
For solve fixture designed by the technical problem as shown in Fig. 2 including bottom plate 1, bearing 2, support ring 3, guide block 4,
Set solid on bearing 2, bearing 2 on lower carrier plate 5, upper cover plate 6, gland 7, O-ring 8, screw 9, compression spring 10, the bottom plate 1
Surely set to set to set on guide block 4, guide block 4 in support ring 3, support ring 3 and spring 10, bullet are set in spring eye, the spring eye
One end of spring 10 is fixed in support ring 3；The top of guide block 4 sets gland 7, and the top of gland 7 sets lower carrier plate 5 and upper cover plate 6, on
O-ring 8 is set between cover plate 6 and lower carrier plate 5, screw 9 is set between gland 7 and lower carrier plate 5.
It is as follows using step：
Step 1: it is corresponding cylindrical that upper cover plate 6, O-ring 8 and lower carrier plate 5 be attached into working position on workpiece 11 during clamping, so
Screw 9 is tightened into compression afterwards；
Step 2: the component that bottom plate 1, bearing 2, support ring 3, guide block 4 and compression spring 10 are constituted is put into lathe work
Centering on platform；
Step 3: the mounted workpiece of step one and Auxiliary support are put on the component that step 2 is assembled；
Step 4: gland 7 two parts will be connected up and down by screw, so as to realize the function of Auxiliary support.
Using the tooling system for lengthening cutter and tool rest, improve cutter and overhang and tooling system rigidity, knife rest figure such as Fig. 3.
By above-mentioned measure, whole component system of processing is rigidly significantly increased, and chatter no longer occurs for processing, using numerical control lathe
The mode of cutting can reach design requirement.
