The hollow static blade milling lead and trailing edge fixture device is characterized by also comprising a profile compressing block, wherein the profile compressing block is fixed on a compressing beam; both ends of the compressing beam are arranged on the bottom plate by pressure plate supports; and both ends of the bottom plate are fixed on the four-axis rotary machine tool by a rotary disk of the four-axis rotary machine tool.
Description
Technical field
The utility model relates to hollow shelf class stator blade processing of leaves frock technical field, is specially a kind of hollow stationary blade that is used for four revolution lathes and mills into lagging edge grip device.
Background technology
Hollow shelf class stator blade is by interior back of the body two boards material, is welded after the punching press, and its turnover vapour side slope mouth size and angle for plate has very high requirement.The turnover vapour side slope mouth of hollow stationary blade entodorsum in the past mostly be by manual grinding or utilize three lathes fixedly milling obtain; Wherein the precision of manual grinding is low; The tolerance of its bevel angle is uncontrollable in ± 2 ° of scopes, and the uniformity of manual grinding is also relatively poor, and its groove size often can not once be polished and put in place; Need repeatedly repair, working (machining) efficiency is low; Though and the turnover vapour side slope mouth size precision of utilizing three lathes fixedly to mill out is high than the manual grinding precision; But its milling of advancing lagging edge need separately be carried out; Therefore back of the body two boards material needs twice clamping in, and its working (machining) efficiency is low, and the profile distortion that while twice clamping causes also can cause the deviation of turnover vapour side slope mouth size; Thereby influence the precision of bevel for welding size, the uniformity of lagging edge and the quality of bevel for welding are advanced in influence.In order to improve machining accuracy and working (machining) efficiency; The lagging edge of attempting at present adopting four revolution lathes to carry out hollow stationary blade that mills is processed; Adopt the lagging edge that advances of four revolution lathe milling hollow stationary blades, its needs are wanted the clamping location No. one time, can effectively guarantee the into uniformity of lagging edge; Improve the bevel for welding quality; Improve working (machining) efficiency, but be used for three lathes fixedly the grip device of milling see Fig. 1, its overall fixed is in three lathe platforms; Hollow stationary blade to be processed is positioned on the anchor clamps profile locating piece 5, it only compresses through two end clamp plates 6, and it is directly applied to four revolution lathes, and it exists blade to compress problems such as instability, the blade positioning and rigid is not enough, the blade surface chatter mark is more.
Summary of the invention
To the problems referred to above; The utility model provides a kind of hollow stationary blade that is used for four revolution lathes to mill into lagging edge grip device, and it can solve, and the blade that adopts three fixing machine lathe milling fixture devices to exist compresses instability, rigidity is not enough, blade surface chatter mark problem how.
Its technical scheme is such; It comprises base plate, profile locating piece; Said profile locating piece is fixed in said base plate; It is characterized in that: it also comprises the profile compact heap, and said profile locating piece cooperates with interior, the back of the body arc plate profile of hollow stationary blade to be processed with the profile of profile compact heap, and said profile compact heap is fixed in and compresses crossbeam; The said crossbeam two ends that compress are installed on said base plate through plate bearing, and said base plate two ends are fixed on said four revolution lathes through the rotary disk of four turn-around machine lathes.
It is further characterized in that: said compressing is connected through housing screw between crossbeam and the said profile compact heap and locks; On the said base plate, the medial extremity of said two ends plate bearing also is separately installed with major part positioning seat and microcephaly's positioning seat; Said major part positioning seat and microcephaly's positioning seat are provided with alignment pin, and said alignment pin cooperates the location with the centre of location hole interior, back of the body arc plate of said hollow stationary blade to be processed.
Adopt the utility model grip device; Its beneficial effect is: profile locating piece and profile compact heap are held blade profile tightly jointly, and blade compresses reliable and stable, and have strengthened the rigidity of blade location; Thereby reduce the blade surface chatter mark, improved the blade surface quality.
