Abstract

The utility model is related to a kind of engine lathe beveled aperture Special Fixture for Machining, including stationary fixture, modular fixture, alignment pin, hold-down bolt and pressing plate.The positioning of parts to be processed and modular fixture is realized by alignment pin, and clamping is realized using hold-down bolt and pressing plate.Modular fixture can provide the flexible jig of different gradients, to adapt to the different gradients of parts to be processed beveled aperture, realize seriation and generalization.Modular fixture is bolt-connected on stationary fixture, and clamped with scroll chuck, you can the processing on engine lathe to component with inclined plane hole is realized.Modular fixture also includes rectangular channel and key, and modular fixture is evenly equipped with 12 groups of rectangular channels with stationary fixture mounting surface outer rim, key is inserted in rectangular channel, and the fine setting to parts to be processed setting angle can be achieved.The special fixture is simple in construction, and versatility is good, and part processing cost is low.

Description

A kind of engine lathe beveled aperture Special Fixture for Machining
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.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.
A kind of engine lathe beveled aperture Special Fixture for Machining, as shown in Figure of description 1, including stationary fixture 2, is pressed from both sides in groups Tool 3, alignment pin 4, hold-down bolt 5 and pressing plate 6.Stationary fixture 2 is cylindrical structure, and modular fixture 3 is wedge-shaped cylindrical structure, fixed Fixture 2 and the bolt connection of modular fixture 3;The part mounting surface center of modular fixture 3 has dowel hole, uniform 4 sets of outward flange Hold-down bolt 5 and pressing plate 6, for installing parts to be processed 7, as shown in Figure of description 2.
Embodiment
In use, realizing the positioning of parts to be processed 7 and modular fixture 3 by alignment pin 4, and use the He of hold-down bolt 5 Pressing plate 6, which is realized, to be clamped.Wherein, modular fixture 3, as shown in Figure of description 3, it is possible to provide the flexible jig of different gradients, with suitable The different gradients of parts to be processed beveled aperture are answered, seriation and generalization is realized.Modular fixture 3 is bolt-connected to fixation On fixture 2, and clamped with scroll chuck 1, you can realize the processing on engine lathe to component with inclined plane hole.Key 32 is inserted At the rectangular channel 31 of modular fixture 3, as shown in accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, you can realize to the installation site of parts to be processed 7 Fine setting.The design centre lightening hole of stationary fixture 2, the uniform loss of weight through hole at non-cooperation of modular fixture 3.
Embodiment described above is only that embodiment of the present utility model is described, not to the utility model Spirit and scope be defined.On the premise of the utility model design concept is not departed from, this area ordinary person is to this reality The all variations and modifications made with new technical scheme, all should drop into protection domain of the present utility model, and this practicality is new The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained All changes in justice and scope are included in the utility model, any reference in claim should not be considered as into limitation Involved claim.
