Abstract
The invention discloses an auxiliary clamping method and an auxiliary clamp for five-axis NC machine tool steam passage workpieces, and belongs to the technical field of clamping of NC machine tool workpieces. The auxiliary clamping method and the auxiliary clamp solve the problem that blade displacement happens in the adjustment process of a clamp on a machine tool driving shaft when existing large blades on a turbine are machined on a Ferrari NC machine tool. According to the clamping method, a clamping clamp blade root fixing centre on a driving shaft of a Ferrari machine tool, a driven shaft of the Ferrari machine tool and a corresponding centre hole of a blade to be machined are clamped and fixed; the blade to be machined and a clamping clamp are clamped and located at a clamping clamp blade root fixing centre position by adopting the auxiliary clamp; the blade to be machined and the corresponding blade root centre hole in the blade to be machined are matched, and then auxiliary clamping is completed; one end of an opening side of a clamping framework of the auxiliary clamp is fixedly connected with a bolt, the bolt is in threaded connection with a fastening screw, the spiral advancing direction of the fastening screw faces towards the other side of the opening side of the clamping framework and is parallel to the upper frame of the clamping framework. The auxiliary clamping method and the auxiliary clamp are used for auxiliary clamping of the steam passage workpieces.
Description
Technical field
The present invention relates to auxiliary clamping method and the auxiliary clamp of five-axle number control machine tool steam passage workpiece, belong to the fixture technology field of Digit Control Machine Tool workpiece.
Background technology
The large-scale blade of steam turbine there will be offset phenomena when five axle Ferrari Digit Control Machine Tool fine finishining clampings, cause offset phenomena former because: on the lathe bed surface of Ferrari, have two rotating shafts, wherein large is driving shaft, and the clamping device of blade processing is fixed on this driving shaft; What one end was little relatively is driven shaft, and the integral shroud centre hole of blade is corresponding with it, and hydraulic clamp.At present, treat that accurately machined large-scale blade is generally root two centre holes, bizet one centre hole location.Therefore, current blade fixture is in when design, and two centre holes of considering root of blade can not guarantee in full accordly adding in batch man-hour, and a root thimble of fixture is set to fixed form, and another root is arranged to adjustable state.When described blade fixture and Ferrari lathe are together used, there will be following phenomenon: on fixture during stressed the holding out against of adjustable root thimble, this power can cause the thimble that heads on integral shroud centre hole, be that driven shaft surpasses hydraulic coupling and then moves, thereby make to occur offset phenomena between the fixedly thimble of fixture root and corresponding centre hole, and then make the leaf quality that processes bad.
Summary of the invention
The present invention seeks on the Digit Control Machine Tool of Ferrari, to add man-hour in order to solve the large-scale blade of existing steam turbine, on lathe driving shaft, the adjustment process of fixture can cause the problem of blade displacement, and a kind of auxiliary clamping method and auxiliary clamp of five-axle number control machine tool steam passage workpiece is provided.
The auxiliary clamping method of five-axle number control machine tool steam passage workpiece of the present invention, it comprises the following steps:
Step 1: by clamping device blade root on the lathe driving shaft of Ferrari fixedly the respective top pin hole clamping of thimble and Ferrari lathe driven shaft and blade to be processed fix;
Step 2: adopt auxiliary clamp clamping device blade root fixedly thimble place by blade to be processed and clamping device clamping and positioning;
Step 3: adjust the adjustable thimble of clamping device blade root, it is coordinated with corresponding blade root centre hole on blade to be processed, complete the auxiliary clamping of blade to be processed;
Step 4: dismantle auxiliary clamp, complete the clamping of blade to be processed.
, this auxiliary clamp is for realizing the auxiliary clamping of the auxiliary clamping method blade to be processed of five-axle number control machine tool steam passage workpiece described in claim 1, and described auxiliary clamp is comprised of clamp frame, bolt and trip bolt,
Clamp frame is a door word frame, and one end of this clamp frame open side is fixedly connected with bolt, and bolt is threaded with trip bolt, and the spiral direction of advance of trip bolt is towards the opposite side of clamp frame opening, and parallel with the upper side frame of clamp frame.
In clamp frame with bolted vertical section be shorter in length than another vertical section of clamp frame, the end of trip bolt with described another vertically medial surface of section is relative.
Advantage of the present invention: the present invention, by setting up an auxiliary clamp, coordinates existing clamping device realization on the Digit Control Machine Tool of Ferrari to treat the fixing of machining blade position, has realized simply and easily the location for the treatment of machining blade.The blank state of its blade during for fine finishining, when integral shroud position centre hole and blade root fixedly centre hole fixing after, while adjusting adjustable blade root thimble, because of the difference of each staff strength, and the situation that causes integral shroud position driven shaft to move.The present invention, fixes the station of blade to be processed fixedly after thimble location positioning at integral shroud position and blade root position, and while making to adjust capable of regulating blade root thimble, driven shaft does not produce displacement, thereby makes the blade high conformity that machines, has guaranteed the total quality of blade.
Accompanying drawing explanation
Fig. 1 is the structural representation of auxiliary clamp of the present invention.
The specific embodiment
The specific embodiment one: below in conjunction with Fig. 1, present embodiment is described, the auxiliary clamping method of five-axle number control machine tool steam passage workpiece described in present embodiment, it comprises the following steps:

Step 2: adopt auxiliary clamp clamping device blade root fixedly thimble place by blade to be processed and clamping device clamping and positioning;
Step 3: adjust the adjustable thimble of clamping device blade root, it is coordinated with corresponding blade root centre hole on blade to be processed, complete the auxiliary clamping of blade to be processed;
Step 4: dismantle auxiliary clamp, complete the clamping of blade to be processed.
In present embodiment, adopt auxiliary clamp that the blade after clamping device and clamping is fixedly clamped at thimble position blade root, and then adjust adjustable blade root position thimble, like this, just can not cause the displacement of integral shroud position driven shaft.Auxiliary clamp has played the effect of auxiliary clamp, after the complete clamping of blade, just auxiliary clamp can be removed.Blade can normal process.
