Abstract
The utility model relates to a clamp used for flattening and inner circle processing of a turbine support ring sleeve, in particular to a flattening and processing clamp used for a gas turbine high-speed power turbine support ring sleeve. The flattening and processing clamp used for the gas turbine high-speed power turbine support ring sleeve resolves the problems that no suitable clamp exists when an existing gas turbine high-speed power turbine support ring sleeve is flattened and an inner circle is processed, and therefore the manufacturing is difficult. A right clamp body and a left clamp body are arranged on a support frame, a workpiece to be machined is arranged in a limiting groove which is matched with the workpiece to be machined in shape and is formed by a first semi-circle arc groove and a second semi-circle arc groove, the right clamp body and the left clamp body are connected through a positioning block and a connection piece, one end of a screw jack is connected with the support frame, the other end of the screw jack is connected with the outer wall of the right clamp body, the width of the positioning block is 62mm, a baffle is arranged on the support frame, and the side wall of the right clamp body contacts the baffle. The flattening and processing clamp is used for flattening and processing the gas turbine high-speed power turbine support ring sleeve.
Description
Technical field
The utility model relates to a kind of turbine support ring and adds the anchor clamps of using man-hour with flattening and the inner circle of overlapping.
Background technology
Certain type gas turbine has adopted many new technologies, new material, new construction in design, causes the planform of part complicated, and machining accuracy, surface roughness require high.Because high voltage power turbine part turn up 5500rpm, so antiwhip is put forward very high requirement, stability that need to be when bearing outer ring adds a pretightning force and guarantees bearing rotary with this, this pretightning force is to provide with the ellipse cover of high resiliency potential energy very by one, because so the material that the very high oval cover of temperature adopts is 8Cr2Ni4WA, belong to high-strength alloy carburizing steel, owing to be that ellipse need to be pressed into oval processing inner circle and cylindrical to annulus under the prerequisite that leaves very large surplus, could produce so larger internal stress to produce larger elastic potential energy simultaneously.Because the blank annulus is thicker and diameter is less so flat pressure need to reach 10T, make flattening and processing inner circle become huge difficult problem.
The utility model content
The utility model is enclosed within flattening and processes interior bowlder without suitable anchor clamps in order to solve existing gas turbine high speed power turbine support ring, cause making hard problem, a kind of flattening and clamp for machining that supports ring set for gas turbine high speed power turbine is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described anchor clamps comprise support, screw jack, right clamp body, locating piece, left clamp body and two connectors, support is provided with right clamp body and left clamp body, the sidewall of right clamp body has the semicircular arc groove, have the second semicircular arc groove corresponding with the first semicircular arc groove on the sidewall of left clamp body, in the stopper slot that to be processed that be located at that the first semicircular arc groove and the second semicircular arc groove form and to be processed shape are complementary, right clamp body be connected clamp body and connect by locating piece and connector, one end of screw jack is connected with support, the other end of screw jack is connected with the outer wall of right clamp body, the width of locating piece is 62mm, support is provided with baffle plate, and the sidewall of right clamp body contacts with baffle plate.
The utlity model has following beneficial effect: the utility model can accurately have gas turbine the stable flattening of cover of huge elastic potential energy, so because the existence of limited location piece does not need to measure the flattening amount, make process operation simple, efficient is high, labour intensity is little, is fit to promote.
