Abstract
The auxiliary clamping method of five-axle number control machine tool steam passage workpiece and auxiliary clamp, belong to the fixture technology field of Digit Control Machine Tool workpiece.The present invention adds man-hour, the problem that on lathe driving shaft, the adjustment process of fixture can cause blade to be shifted to solve the large-scale blade of existing steam turbine on the Digit Control Machine Tool of Ferrari.Clamping method: the respective top pin hole clamping that clamping device blade root on the lathe driving shaft of Ferrari fixes thimble and Ferrari lathe driven shaft and blade to be processed is fixed; Auxiliary clamp is adopted to fix thimble place by blade to be processed and clamping device clamping and positioning clamping device blade root; Its blade root centre hole corresponding on blade to be processed is coordinated, completes auxiliary clamping; One end of the clamp frame open side of auxiliary clamp 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.The present invention is for realizing the auxiliary clamping of steam passage workpiece.
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, the reason of offset phenomena is caused to be: Ferrari lathe bed surface to have two rotating shafts, wherein large is driving shaft, and the clamping device of blade processing is fixed on this driving shaft; What opposite side was little 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 hole, bizet one centre hole is located.Therefore, current blade fixture is when designing, and consider that two centre holes of root of blade can not ensure completely the same when processing in batching, a root thimble of fixture is set to fixed form, and another root is then arranged to adjustable state.When described blade fixture and Ferrari lathe are together used, there will be following phenomenon: when root thimble adjustable on fixture is stressed hold out against time, this power can cause the thimble heading on integral shroud centre hole, namely driven shaft exceedes hydraulic coupling and then moves, thus make to occur offset phenomena between the fixing 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 solving the large-scale blade of existing steam turbine, the problem that on lathe driving shaft, the adjustment process of fixture can cause blade to be shifted, provides a kind of auxiliary clamping method and auxiliary clamp of five-axle number control machine tool steam passage workpiece.
The auxiliary clamping method of five-axle number control machine tool steam passage workpiece of the present invention, it comprises the following steps:
Step one: the respective top pin hole clamping that clamping device blade root on the lathe driving shaft of Ferrari fixes thimble and Ferrari lathe driven shaft and blade to be processed is fixed;
Step 2: adopt auxiliary clamp to fix thimble place by blade to be processed and clamping device clamping and positioning clamping device blade root;
Step 3: the adjustable thimble of adjustment clamping device blade root, makes its blade root centre hole corresponding on blade to be processed coordinate, complete the auxiliary clamping of blade to be processed;
Step 4: dismounting auxiliary clamp, completes the clamping of blade to be processed.
A kind of auxiliary clamp, this auxiliary clamp for realize five-axle number control machine tool steam passage workpiece described in claim 1 auxiliary clamping method in the auxiliary clamping of blade to be processed, described auxiliary clamp is made up of clamp frame, bolt and trip bolt,
Clamp frame is 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.
With another vertical section being shorter in length than clamp frame of bolted vertical section in clamp frame, the end of trip bolt is relative with the medial surface of another vertical section described.
Advantage of the present invention: the present invention, by setting up an auxiliary clamp, coordinates existing clamping device on the Digit Control Machine Tool of Ferrari to realize treating the fixing of machining blade position, achieves the location for the treatment of machining blade simply and easily.It is for the green state of blade during fine finishining, namely when integral shroud position centre hole and blade root fix centre hole fixing after, when adjusting adjustable blade root thimble, because of the difference of each staff strength, and cause the situation of integral shroud position driven shaft movement.The present invention fixes after thimble position determines at integral shroud position and blade root position, and fixed by the station of blade to be processed, when making adjustment adjustable blade root thimble, driven shaft does not produce displacement, thus makes the blade uniformity that machines good, ensure that the total quality of blade.
Accompanying drawing explanation
Fig. 1 is the structural representation of auxiliary clamp of the present invention.
Detailed description of the invention
Detailed description of the invention one: present embodiment is described below in conjunction with Fig. 1, the auxiliary clamping method of five-axle number control machine tool steam passage workpiece described in present embodiment, it comprises the following steps:
Step one: the respective top pin hole clamping that clamping device blade root on the lathe driving shaft of Ferrari fixes thimble and Ferrari lathe driven shaft and blade to be processed is fixed;
Step 2: adopt auxiliary clamp to fix thimble place by blade to be processed and clamping device clamping and positioning clamping device blade root;
Step 3: the adjustable thimble of adjustment clamping device blade root, makes its blade root centre hole corresponding on blade to be processed coordinate, complete the auxiliary clamping of blade to be processed;
Step 4: dismounting auxiliary clamp, completes the clamping of blade to be processed.
Adopt auxiliary clamp that the blade after clamping device and clamping is fixed thimble position blade root in present embodiment to clamp, and then adjust adjustable blade root position thimble, like this, the displacement of integral shroud position driven shaft would not be caused.Auxiliary clamp serves the effect of auxiliary clamp, when after the complete clamping of blade, just auxiliary clamp can be removed.Blade namely can normal process.
Detailed description of the invention two: present embodiment is described below in conjunction with Fig. 1, auxiliary clamp described in present embodiment, this auxiliary clamp for realize five-axle number control machine tool steam passage workpiece described in embodiment one auxiliary clamping method in the auxiliary clamping of blade to be processed, described auxiliary clamp is made up of clamp frame 1, bolt 2 and trip bolt 3
Clamp frame 1 is door word frame, and one end of this clamp frame 1 open side is fixedly connected with bolt 2, and bolt 2 is threaded with trip bolt 3, and the spiral direction of advance of trip bolt 3 is towards the opposite side of clamp frame 1 opening, and parallel with the upper side frame of clamp frame 1.
Present embodiment in use, is fixed thimble place clamping device blade root and blade to be processed and clamping device to be clamped between the opening of clamp frame 1, regulate trip bolt 3 to be fixedly clamped by it.
Detailed description of the invention three: present embodiment is described below in conjunction with Fig. 1, present embodiment further illustrates embodiment two, clamp frame 1 is connected with bolt 2 another vertical section being shorter in length than clamp frame 1 of vertical section, the end of trip bolt 3 is relative with the medial surface of another vertical section described.
