Abstract
The utility model discloses a heavy caliber 90-degrees elbow clamping device, comprises a frame; two concentric round tracks are disposed on the base; a boring/cutting apparatus installation base is mounted on the rails; the elbow is installed on the base by a locking device; the locking device is mounted on the base, and can move along the rail arc direction on the base. The clamping device can realize the metalworking on the inner wall and outer wall of the elbow, guarantee the surface smoothness of the inner and outer wall, enables the heavy caliber elbow to be used in nuclear industry, and guarantee the safety of nuclear conveying pipelines.
Description
Technical field:
The utility model relates to the process technology of 90 ° of elbows of a kind of large diameter pipeline, relates in particular to the fixture technology of 90 ° of elbows of a kind of heavy caliber.
Background technology:
The large-diameter centrifugal casting pipeline can be used for the employed high alloy conversion tube of petroleum chemical industry, concetrated pipe and cracking of ethylene pipe etc., and the conveyance conduit of nuclear power plant is used.This pipeline in course of conveying because the variation in geographical position, in process of deployment, must use 90 ° of elbows, for the heavy caliber straight pipeline, present process technology is full maturity, and also do not possess this technology now for the process technology of bigbore elbow, it now mainly is the surface smoothness that satisfies elbow interior wall by the technology that improves casting, adopt the metalworking technology to process the part that the elbow two ends cooperate with straight tube then, as boring endoporus etc., other inner wall section and excircle part for elbow can't be processed, in case the fineness of elbow does not reach certain requirement, damping phenomena can appear when pumped (conveying) medium, choking phenomenon can occur after time is long, the conveyance conduit of nuclear power plant is particularly important, and inside and outside wall must reach the requirement of certain surface roughness by processing.
The utility model content:
The clamping device that the utility model purpose is to provide a kind of novel 90 ° of elbows of heavy caliber comes the inwall and the cylindrical of elbow are processed by this clamping device, improves the surface smoothness of elbow interior wall, avoids damping phenomena can occurring when pumped (conveying) medium.
The utility model is achieved in that the clamping device of 90 ° of elbows of a kind of heavy caliber, comprise base, it is characterized in that: two concentric circuit orbits are arranged on described base, bore hole and topping machanism mounting seat are installed on the described track, described two bases move on described track, elbow is installed on the described base by locking device, and described locking device is sleeved on the described base, and this locking device can move in the circular arc direction of the described track in described base upper edge.
The utility model compared with prior art has following advantage:
Because the mounting seat of bore hole and topping machanism is installed on this clamping device, can realize the metalworking of the inner and outer wall of elbow by this device, guarantee the surface smoothness of elbow inside and outside wall, large caliber bend can be used on nuclear industry, guarantee the safety of nuclear conveyance conduit.
