Abstract
The utility model discloses a kind of turntable frock for aviation part processing, comprise three claws, a positioning core axle and nut, described positioning core axle is divided into thread segment, positioning section, step section and clamp segment from top to bottom, described three claws are in 120 ° and the clamp segment of positioning core axle bottom are clamped by front end, and described nut thread is connected on the thread segment of positioning core axle.The beneficial effects of the utility model are: aviation part can realize more high-precision Set and Positioning, and is fixed fast by nut; Clamped one time, then uses three axis numerically controlled machine just can complete whole following process, significantly saved production and processing cost and production efficiency, and product quality is also improved.
Description
Technical field
The utility model relates to processing tool technical field, particularly a kind of turntable frock for aviation part processing.
Background technology
Our unit is at present at a certain aviation part of processing, and its structure as shown in Figure 1, 2, 3.The production lot of this aviation part is large, and quality requirement is high, and each part must by process operation person self-inspection after production completes, and the qualified rear dish of self-inspection can be delivered to special inspection place and recheck, thus strict guarantee product quality.
Because this design of part size is very little, each locations of structures and dimension precision requirement are very high, and Set and Positioning, processing, detection supervisor all need to design special instrument, and those general instruments all can not meet requirement at present.
According to the Equipments Setting situation of our unit, the number of devices of four axles and Five-axis NC Machining Center is limited, be difficult to the production in enormous quantities ensureing this aviation part, and three axis machining central apparatus is sufficient, therefore can only considers to adopt three axis machining center to solve the production task of this part.Therefore, specialized designs is needed can be used in frock clamp on three axis machining central apparatus.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of turntable frock for aviation part processing, for the Set and Positioning of aviation part and fixing.
The technical solution adopted in the utility model is such:
A kind of turntable frock for aviation part processing, comprise three claws, a positioning core axle and nut, described positioning core axle is divided into thread segment, positioning section, step section and clamp segment from top to bottom, described three claws are in 120 ° and the clamp segment of positioning core axle bottom are clamped by front end, and described nut thread is connected on the thread segment of positioning core axle.
As preferably, described claw front end is interior concaved circular cambered surface termination.Use interior concaved circular cambered surface termination, still first the arc surface from indent in the past being contacted bit transitions is in the art point cantact location, can improve the positioning precision of positioning core axle.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: positioning core axle is for this kind of aviation part specialized designs; Aviation part can realize more high-precision Set and Positioning, and is fixed fast by nut; Clamped one time, then uses three axis numerically controlled machine just can complete whole following process, significantly saved production and processing cost and production efficiency, and product quality is also improved.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment:
As shown in Figure 4,5, a kind of turntable frock for aviation part processing, comprise three claws, 1, positioning core axle 2 and nut 3, described positioning core axle 2 is divided into thread segment 2-1, positioning section 2-2, step section 2-3 and clamp segment 2-4 from top to bottom, described three claws 1 are in 120 ° and are clamped by the clamp segment 2-4 of positioning core axle 2 bottom by front end, and described nut 3 is threaded on the thread segment 2-1 of positioning core axle 2.Described claw 1 front end is interior concaved circular cambered surface termination 1-1, as shown in Figure 6.
After aviation part to be processed is enclosed within the positioning section 2-2 of positioning core axle 2, then nut 3 is installed, aviation part is compressed.
By working out the nc program of this aviation part on lathe, after making a face completion of processing of this aviation part, numerical control rotating platform of the present utility model is rotational workpieces under the control of nc program, the next machined surface of this aviation part is made to be in Working position, until all machined surfaces of this aviation part machine.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
