Description
Technical field
The utility model belongs to field of machining, is related to special fixture, especially a kind of engine lathe inclined-plane hole machined
Special fixture.
Background technology
Special fixture is the equipment manufactured and designed for a certain procedure processing of part, is stablized relatively, in batches in product
Used in larger production；Labor intensity when it can be effectively reduced work in process of production, raise labour productivity, simultaneously
Obtain higher machining accuracy.
During inclined-plane hole machined, part location difficulty is easily deformed during clamping, is reduced the quality of product, is extended
The time of part processing, production efficiency is reduced, therefore typically design specialized fixture is needed during inclined-plane hole machined.But existing fixture is general
Structure is complex, and installation and debugging are difficult, and without versatility, is only used for the processing of single gradient beveled aperture.And use
Multi-shaft numerical control milling machine is processed, and processing cost is higher, and should not be added when requiring higher to beveled aperture machined surface quality using milling
Work mode.
Utility model content
For above-mentioned situation, the technical problems to be solved in the utility model is to provide one kind can process zero on engine lathe
The special fixture of part beveled aperture, the processing in component with inclined plane hole can be completed on engine lathe, processing cost is greatly reduced.
The technical solution of the utility model is as follows：
A kind of engine lathe beveled aperture Special Fixture for Machining, including stationary fixture, modular fixture, alignment pin, hold-down bolt
And pressing plate.
Stationary fixture is cylindrical structure, and modular fixture is wedge-shaped cylindrical structure, stationary fixture and modular fixture bolt connection；
The part mounting surface center of modular fixture has dowel hole, the uniform 4 sets of hold-down bolts in outward flange and pressing plate, to be added for installing
Work part；Modular fixture also includes rectangular channel and key, and modular fixture is evenly equipped with 12 groups of rectangles with stationary fixture mounting surface outer rim
Groove, inserts key in rectangular channel, and the fine setting to parts to be processed setting angle can be achieved.
The dowel hole of modular fixture is inserted in alignment pin one end, and other end insertion parts to be processed centre bore is realized to be added
Work part is accurately positioned.
Modular fixture uses seriation structure design, and wedge angle is 5~15 °, 1 ° of interval, totally 10 groups, for different oblique
Spend the turnery processing in component with inclined plane hole.
Preferably, stationary fixture design centre lightening hole, is easily installed debugging.
Preferably, modular fixture uniform loss of weight through hole at non-cooperation.
Effect and benefit of the present utility model are：
(1) the engine lathe beveled aperture Special Fixture for Machining can be used for there is provided seriation, modular modular fixture
The processing of different gradient hole in piece part；
(2) special fixture is simple in construction, easy for installation, improves its function universality, expands the range of work of lathe, drop
The processing cost of low beveled aperture part.
