Abstract
The invention provides a hollow static blade leading and trailing edge milling clamp device for a four-axis rotary machine tool. By the device, the problems of unstable blade compaction, insufficient rigidity and multiple blade surface vibrating lines in a milling clamp device for a three-axis fixed machine tool can be solved. The device comprises a base plate and a profile positioning block, wherein the profile positioning block is fixed on the base plate. The device is characterized by also comprising a profile compacting block, wherein profiles of the profile positioning block and the profile compacting block are matched with those of an inner arc plate and a back arc plate of a hollow static blade to be machined; the profile compacting block is fixed on a compacting beam; two ends of the compacting beam are arranged on the base plate by pressing plate supports; and two ends of the base plate is fixed on the four-axis rotary machine tool by rotary discs of the four-axis rotary machine tool.
Description
Technical field
The present invention relates to the processing tool technical field of hollow shelf class stator blade blade, be specially for the hollow stationary blade milling of four axle revolution lathes and enter lagging edge grip device.
Background technology
Hollow shelf class stator blade is by interior back of the body two boards material, after punching press, is welded, 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 axle lathes fixedly milling obtain, wherein the precision of manual grinding is low, the tolerance of its bevel angle is uncontrollable within the scope of ± 2 °, and the uniformity of manual grinding is also poor, its groove size often can not once be polished and put in place, need repeatedly repair, working (machining) efficiency is low; And although the turnover vapour side slope mouth size precision of utilizing three axle lathes fixedly to mill out is high compared with manual grinding precision, but its milling of entering lagging edge need to separately be carried out, therefore in, back of the body two boards material needs twice clamping, its working (machining) efficiency is low, the profile distortion that while twice clamping causes also can cause the deviation of turnover vapour side slope mouth size, thereby affect the precision of bevel for welding size, affect into the uniformity of lagging edge and the quality of bevel for welding.In order to improve machining accuracy and working (machining) efficiency, attempt at present adopting four axle revolution lathes to carry out the milling lagging edge processing of hollow stationary blade, adopt the lagging edge that enters of four axle revolution lathe milling hollow stationary blades, its needs are wanted clamped one time location, can effectively guarantee the uniformity into lagging edge, improve bevel for welding quality, improve working (machining) efficiency, but for three axle lathes fixedly the grip device of milling see Fig. 1, its integral body is fixed on three axle platform of machine tools, hollow stationary blade to be processed is positioned on fixture profile locating piece 5, it only compresses by two end clamp plates 6, it exists blade compression unstable to be directly applied to four axle revolution lathes, blade positioning and rigid is not enough, the problems such as blade surface chatter mark is more.
Summary of the invention
For the problems referred to above, the invention provides for the hollow stationary blade milling of four axle revolution lathes and enter lagging edge grip device, it can solve and adopt the blade that three axle fixing machine lathe milling fixture devices exist to compress problem unstable, that rigidity is not enough, blade surface chatter mark is many.
Its technical scheme is such, it comprises base plate, profile locating piece, described profile locating piece is fixed on described base plate, it is characterized in that: it also comprises profile compact heap, described profile locating piece coordinates with the profile of profile compact heap and interior, the back of the body arc plate profile of hollow stationary blade to be processed, described profile compact heap is fixed on compression crossbeam, described compression crossbeam two ends are installed on described base plate by plate bearing, and described base plate two ends are fixed on described four axle revolution lathes by the rotary disk of four axle revolution lathes.
It is further characterized in that: between described compression crossbeam and described profile compact heap, by housing screw, be connected and locked; The medial extremity of described base plate Shang, two ends plate bearing is also separately installed with major part positioning seat and microcephaly's positioning seat, described major part positioning seat and microcephaly's positioning seat are provided with alignment pin, and described alignment pin coordinates location with the positioning center hole interior, back of the body arc plate of described hollow stationary blade to be processed.
Adopt grip device of the present invention, its beneficial effect is: profile locating piece and profile compact heap are held blade profile tightly jointly, and blade compresses reliable and stable, and has strengthened the rigidity of blade location, thereby reduces blade surface chatter mark, has improved blade surface quality.
