Abstract
The invention provides a held tip mechanism, and relates to the technical field of processing of gas turbine blades. The held tip mechanism effectively prevents vibration of the blades, and does not generate over cutting phenomenon so that the single tip of the caudal vertebra is not easily damaged. The held tip mechanism comprises a base and a rotary shaft sleeve, wherein the rotary shaft sleeve transversely passes through the base, the tail end of the rotary shaft sleeve is connected with a hand wheel, and the front end of the rotary shaft sleeve is connected with a tip. The held tip mechanism is characterized in that: a rotary disc is sleeved on the external circular face of the tip, the circle center of the rotary disc is positioned on the central line of the tip, and clamping frames are fastened at two ends of the same diameter of the rotary disc.

Technical field
The present invention relates to the processing technique field of turbine blade, but be specially held tip mechanism.
Background technology
The turbine blade profile is a distortion profile, and blade profile processing utilizes three centre bores location usually, and root adopts two centre bores, and the centre bore in top adopts three top clamping and positioning, carries out four axles revolution digital control processing at Digit Control Machine Tool.
Along with the development of technology, turbines vane profile width is increasing, weight is more and more heavier, and this brings certain difficulty for blade profile numerical control rotary processing and loading clamp.In the blade actual production process, two problems appear.Problem 1: leaf jacking lagging edge, the vibrations in man-hour are larger adding, and easily produce over-cutting; Problem 2: because blade is heavier, the original tail bone list of lathe is top easily damaged.
Summary of the invention
For the problems referred to above, but the invention provides held tip mechanism, it effectively prevents the vibrations of blade, can not produce over-cutting, and so that the tail bone list is top not fragile.
But held tip mechanism, its technical scheme is such: it comprises base, swivel sleeve, described swivel sleeve laterally runs through described base, described swivel sleeve tail end connects handwheel, front end connects top, it is characterized in that: described top periphery is set with rotary disk, the center of circle of described rotary disk is positioned at described top center line, and the two ends of the same diameter of described rotary disk are fastened with clamping support.
It is further characterized in that: described clamping support comprises support, housing screw, and in the outer face of described rotary disk, the front end two sides of described support are connected with respectively described housing screw in opposite directions to described support by T-shaped screw fastening;
The tail end of described swivel sleeve is fastened with connecting plate, described connecting plate connects the driving double-screw bolt of its afterbody, end cap shrouding internal thread connects the periphery screw thread of described driving double-screw bolt, and described end cap shrouding is fastenedly connected described base, and the afterbody of described driving double-screw bolt is fastenedly connected described handwheel;
Be set with the revolution mandrel in the cavity of described swivel sleeve, the afterbody of described revolution mandrel is fastened with end surface press plate, described revolution mandrel is supported on the inner headed face of described swivel sleeve by the oblique cone bearing, the front end of described revolution mandrel exposes to described base, swivel sleeve, the described top front end center that is anchored on described revolution mandrel, described rotary disk is set in the periphery of described revolution mandrel, top formed evagination;
The below of described swivel sleeve is equipped with latch segment, described latch segment is divided into two, between two described latch segments spring is installed, the outside of described two latch segments is fastenedly connected with respectively locking wrench, the fit periphery bottom of described swivel sleeve, the upper surface of two described latch segments.
After adopting structure of the present invention, during the blade clamping, adopt three centre bores location, with blade install to three top on, by rotation hand wheel, drive swivel sleeve and push ahead, thereby make top compression blade, the clamping support at the same diameter two ends by rotary disk clamps blade afterwards, and it is so that the both sides of blade are clamped, firm position, it effectively prevents the vibrations of blade, can not produce over-cutting, and toply can not be subject to the stress that blade vibration produces, so that the tail bone list is top not fragile.
Description of drawings
Fig. 1 is top view structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 cuts open structural representation;
Fig. 3 is that the B-B of Fig. 1 cuts open structural representation.
The specific embodiment
See Fig. 1, Fig. 2, Fig. 3, it comprises base 1, swivel sleeve 2, swivel sleeve 2 laterally runs through base 1, the tail end of swivel sleeve 2 is fastened with connecting plate 3, connecting plate 3 connects the driving double-screw bolt 4 of its afterbody, end cap shrouding 5 internal threads connect the periphery screw thread that drives double-screw bolt 4, and end cap shrouding 5 is fastenedly connected base 1, and the afterbody that drives double-screw bolt 4 is fastenedly connected handwheel 6;
Be set with revolution mandrel 7 in the cavity of swivel sleeve 2, the afterbody of revolution mandrel 7 is fastened with end surface press plate 8, revolution mandrel 7 is supported on the inner headed face of swivel sleeve 2 by oblique cone bearing 9, the front end of revolution mandrel 7 exposes to base 1, swivel sleeve 2, top 10 are anchored on the front end center of revolution mandrel 7, rotary disk 11 is set in revolution mandrel 7, the periphery of top 10 formed evaginations, the center of circle of rotary disk 11 is positioned at top 10 center line, the two ends of the same diameter of rotary disk 11 are fastened with clamping support, clamping support comprises support 12, housing screw 13, support 12 is anchored on the outer face of rotary disk 11 by T-shaped screw 14, the front end two sides of support 12 are connected with respectively housing screw 13 in opposite directions;
The below of swivel sleeve 2 is equipped with latch segment 15, latch segment 15 is divided into two, between two latch segments 15 spring 16 is installed, the outside of two latch segments 15 is fastenedly connected with respectively locking wrench 19, the periphery bottom of the upper surface applying swivel sleeve 2 of two latch segments 15, two latch segments 15 are installed on the latch segment cavity 17 of base 1, and cover plate 18 mounts cover latch segment cavity 17 both ends of the surface in base 1, the be threaded internal thread through hole of cover plate 18 of the external screw thread of locking wrench 19.
Its operation principle is as follows: by rotation hand wheel 6, promote connecting plate 3, drive swivel sleeve 2 and push ahead, thereby make top 10 to compress blade; Locking wrench 19 by both sides acts on simultaneously, promotes latch segment 15, and swivel sleeve 2 is held tightly from both sides, realizes swivel sleeve 2 lockings, and this moment, spring 16 was in compressive state; By the clamping support of top both sides, utilize housing screw 13 that blade is clamped, realize vane tip auxiliary clamp location.Process, the locking wrench 19 of both sides is unclamped simultaneously, utilize the elastic force of spring 16 that latch segment 15 is pushed open, realize swivel sleeve 2 releases; By rotation hand wheel 6, pulling connecting plate 5 retreats, and drives swivel sleeve 2 and retreats, thereby make top 10 to retreat, and unclamps afterwards housing screw 13, finishes the release process to blade.
