Abstract
The invention provides a locating and clamping device for machining a bacterial type blade shroud, which can effectively reduce influence on the location degree of the blade shroud due to shaped wire deformation, ensure the machining quality of the blade shroud and increase the machining efficiency. The locating and clamping device comprises a clamping base plate, wherein one end part of the clamping base plate is provided with a blade root locating seat. The locating and clamping device is characterized in that the other end of the clamping base plate is provided with a blade shroud compression seat, the oblique extending end of the blade shroud compression seat is provided with a back arc compression block, and the vertical end of the blade shroud compression seat is provided with a blade shroud hinge pressing plate of which the inner side is provided with an inner arc compression block; the blade shroud hinge pressing plate is provided with a trailing edge compression screw; and the blade shroud compression seat is internally provided with a leading edge ejector block.
Description
Technical field
The present invention relates to the blade processing tooling technical field, be specially the positioning and clamping device for mushroom blade shroud processing.
Background technology
The processing of general mushroom blade shroud mainly realizes by five axle rotating-millings, when finishing the milling of steam passage molded line, integral shroud is shaped together, the method working (machining) efficiency is high, back of the body arc high conformity in the blade, and therefore the processing at blade has obtained using very widely.But, blade on the revolution lathe during clamping with the blade root positioning compression, integral shroud is with the centre bore location and hold out against, the steam passage of blade partly is vacant state, and can produce certain machining deformation during with such state milling molded line, the steam passage molded line is thinner, and curvature is larger, and machining deformation is more serious, and when the steam passage molded line near integral shroud has larger distortion, can have a strong impact on the position dimension of each face of integral shroud.Require to be ± 0.05mm such as the integral shroud sagittal plane position degree of certain type product, but position degree can only satisfy ± 0.15mm after the actual processing, and this size also can be elongated and worse and worse along with steam passage.Therefore added man-hour in order to obtain preferably crudy in the revolution of five axles in the past, can only be by reducing cutting output and tool feeding amount, perhaps revise the method for moulding, eliminate the impact that the distortion of blade brings to processing as far as possible, but this still can not reach the dimensional requirement of drawing fully, also has a strong impact on the milling efficiency of blade simultaneously.
Summary of the invention
For the problems referred to above, the invention provides the positioning and clamping device for mushroom blade shroud processing, it can effectively reduce because molded line is out of shape the impact that brings to the integral shroud position degree, guarantees the crudy of integral shroud, improves working (machining) efficiency.
Its technical scheme is such, it comprises the clamping base plate, described clamping base plate one end is equipped with the blade root positioning seat, the described clamping base plate other end is equipped with the integral shroud pressed seat, the oblique external part of described integral shroud pressed seat is equipped with back of the body arc compact heap, the vertical end of described integral shroud pressed seat is equipped with integral shroud hinge pressing plate, and described integral shroud hinge pressing plate installed inside has the inner arc compact heap; On the described integral shroud hinge pressing plate lagging edge housing screw is installed; In the described integral shroud pressed seat leading edge withstanding tight block is installed.
Described inner arc compact heap cooperates with blade profile with back of the body arc compact heap profile.
A kind of positioning and clamping device for mushroom blade shroud processing of the present invention, it is held the integral shroud molded line of blade tightly by the leading edge withstanding tight block on the integral shroud pressed seat, interior arc shaped surface compact heap, convex profile compact heap and trailing edge housing screw, thereby strengthened the rigidity of blade shroud, reduced in the blade milling process owing to the impact of molded line distortion to the integral shroud position degree, improved the integral shroud crudy, also do not needed to eliminate blade by reducing cutting output and tool feeding amount.

Fig. 1 is master's TV structure schematic diagram of the present invention (the integral shroud pressed seat among the figure in the structure of the present invention is expressed emphatically inside admission limit withstanding tight block structure);
Fig. 2 is that the Q of Fig. 1 is to structural representation;
Fig. 3 is that the P of Fig. 1 is to structural representation.
The specific embodiment
See Fig. 1, Fig. 2, Fig. 3, apparatus of the present invention comprise clamping base plate 7, clamping base plate 7 one ends are equipped with blade root positioning seat 1, clamping base plate 7 other ends are equipped with integral shroud pressed seat 2, the oblique external part of integral shroud pressed seat 2 is equipped with back of the body arc compact heap 4, the vertical end of integral shroud pressed seat 2 is equipped with integral shroud hinge pressing plate 3, and integral shroud hinge pressing plate 3 installed inside have inner arc compact heap 5; On the integral shroud hinge pressing plate 3 lagging edge housing screw 8 is installed; Leading edge withstanding tight block 6 is installed in the integral shroud pressed seat 2.Inner arc compact heap 5 cooperates with blade profile with the profile of back of the body arc compact heap 4.Among Fig. 1, Fig. 2 and Fig. 3,9 is blade.
The below specifically describes the process of apparatus of the present invention clamping blade: clamping base plate 7 is installed on lathe, the blade root of blade is fixed on the blade root positioning seat 1, then regulate leading edge withstanding tight block 6 and locking, regulate again integral shroud hinge pressing plate 3 and itself and integral shroud pressed seat 2 is fixing, then regulate back of the body arc compact heap 4, inner arc compact heap 5, and it is pressed on the blade profile, note back of the body arc thrust in the control, can not with the blade compressive strain, after compressing screw lock namely be finished the positioning and clamping of blade.
