Description
One, technical field
The utility model relates to a kind of device of processing of gas turbine straightener(stator) blade, especially blade overall length linear cutting clamp.
Two, background technology
When electric spark linear cutting machine machining blade overall length, if do not use special fixture, be difficult to guarantee the machining accuracy of blade overall length, and the uncertainty of the each clamping position of blade, add man-hour each part and all will carry out a tool setting, so just greatly reduce labor productivity.
Because the diversity of gas turbine blades specification, if in its manufacture process, to remove to design the anchor clamps of overpaying different size for the blade of different size, to adapt to the need of production of different size blade.So not only cause the waste of processing cost, bring inconvenience also for the management of production scene anchor clamps.
The gas turbine straightener(stator) blade of developing a kind of suitable different size cuts total lazy-tongs, not only can alleviate jig Design personnel's workload, saving anchor clamps manufactured materials and production cost, the time that anchor clamps are overpaied in shortening operative employee calibration, and can the management of production scene anchor clamps be brought great convenience.
Three, utility model content
The utility model purpose is that for the problems referred to above, the gas turbine straightener(stator) blade that has proposed a kind of suitable different size cuts total lazy-tongs.The utility model is considered with the basic demand of line cutting and the dimension precision requirement of this blade: the processing request that can guarantee workpiece; Can raise labour productivity again; And make simple, easy to maintenance; The anchor clamps manufacturing cost is lower.
Technical solutions of the utility model are that gas turbine straightener(stator) blade overall length linear cutting clamp comprises setting element and guide and limit element; The setting element of described anchor clamps by left and right sides locating piece, about auxiliary L locating piece, the locating piece that places straightener(stator) blade blade root place consist of with the location-plate that the leaf top is located, about being connected to by hexagon socket head cap screw, left and right sides locating piece on the auxiliary L locating piece, assists on the L locating piece about the location-plate at straightener(stator) blade blade root place's locating piece and place, leaf top is connected in by hexagon socket head cap screw respectively; The guide and limit element of described anchor clamps, comprise two parallel guide pads, auxiliary L locating piece is equipped with detent about described, and in the detent of auxiliary L locating piece, guide pad slided in the detent perpendicular to locating piece about two guide pads were connected in by hexagon socket head cap screw.
When using these anchor clamps to go to cut overall length, after only the spacing between the setting element of the left and right sides need being adjusted by the length dimension of different size blade, then with processing behind the relative position of hexagon socket head cap screw stationary positioned element and director element.
The beneficial effects of the utility model are: the principle of this cover linear cutting clamp is fairly simple, and it is convenient that these anchor clamps are not only adjusted length, clamping fast, simple, make simply, applicable gas turbine blades scope is wide, does not also require for the rotation direction of blade.The waste of having avoided processing to overpay clamp material has reduced jig Design and production cost, the management space of also greatly saving the production scene anchor clamps simultaneously.
Four, description of drawings
Fig. 1 is that the straightener(stator) blade line cuts total lazy-tongs 3D figure;
Fig. 2 is left redundant L locating piece 3D figure;
Fig. 3 guide pad 3D figure.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the utility model anchor clamps comprise setting element, the guide and limit element.
As shown in Figure 1, the setting element of described anchor clamps, consisted of with the location-plate 6 at place, leaf top by left redundant L locating piece 1, right redundant L locating piece 4, left locating piece 2, right locating piece 5, blade root place locating piece 3, choose the specification of left locating piece 2, right locating piece 5 according to the specification of blade; Left locating piece 2, right locating piece 5 are connected on left redundant L locating piece 1, the right redundant L locating piece 4 by hexagon socket head cap screw, and blade root place locating piece 3 is connected on left redundant L locating piece 1, the right redundant L locating piece 4 by hexagon socket head cap screw respectively with the location-plate 6 at place, leaf top.Also comprise hexagon socket head cap screw and pad 8,9 among the figure, the blade root 10 of straightener(stator) blade, blade profile 11, leaf top 12.Wherein the surface of at least one guide pad is provided with scale.
The guide and limit element of described anchor clamps is fixed on two guide pads by two guide pads 7, described left redundant L locating piece 1, right redundant L locating piece 4 as shown in Figure 1, assists in the L piece locating groove about guide pad is connected in by hexagon socket head cap screw.During assembling the left surface of the W face (see figure 2) on the 0 graduation mark guide pad 7 on the guide pad 7 and left redundant L locating piece 1 is fitted, can realize easily that datum line overlaps.When place, processing leaf top overall length, need to remove place, leaf top location-plate 6, unclamp the connection hexagon-headed bolt that guide pad 7 is connected with right redundant L piece, length of blade according to different stage, the right flank of adjusting right redundant L piece 4 compresses hexagon socket head cap screw to guide pad 7 corresponding graduation mark places, it is fixed, and then gas turbine blades is positioned on left locating piece 2 and the right locating piece 5, the blade root end face contacts with blade root place locating piece 3, compresses and can process with magnetic block absorption or the U-shaped pressing plate of standard.When the processing leaf is followed place's overall length, need remove blade root place locating piece 3, load onto place, leaf top location-plate 6.Method is consistent when locating overall length with processing leaf top.
On the auxiliary L piece locating groove is arranged all about the utility model, and on the guide pad scale is arranged all, can easily determine the position of length direction.These anchor clamps also have certain symmetry, can easily realize processing the exchange of left-right rotary blade.
This folder also has certain symmetry, and is in full accord at blade parameter, only in the inconsistent situation of rotation direction, only behind the location swap of need with left locating piece 1 and right locating piece 5, can easily realize the exchange of blade rotation direction.And need not at redesign one sub-folder tool.
