Description

Frock is repaired to sleeve pipe of turboshaft engine fuel house steward Technical Field The utility model relates to the technical field of pipe sleeve repair, in particular to a pipe sleeve repair tool for a fuel oil main pipe of a turboshaft engine. Background The sleeve for the fuel oil main pipe of the certain Russian aviation turboshaft engine is worn after long-term use, and two concave punching point insurance traces need to be repaired during maintenance and then put into use again. In the prior art, the copper rod and the hammer are manually used for repeatedly knocking and repairing, but the manual correction is difficult to position due to the small sleeve structure with the maximum diameter of 17mm, the manual operation difficulty is high, the manual one-time knocking time is about 5 minutes, the time and the efficiency are low, and the requirements on the skill of operators are high due to the fact that the sleeve wall thickness is only 0.5mm, if the manual positioning is inaccurate, the pipe wall cracks and internal thread crush injuries are easily caused by repeated multiple times of knocking, and the problem of scrapping is solved. Disclosure of utility model It is an object of the present utility model to address at least the above problems and/or disadvantages and to provide at least the advantages described below. To achieve these objects and other advantages and in accordance with the purpose of the utility model, there is provided a bushing repair fixture for a fuel manifold of a scroll engine, comprising a support having a threaded through-hole column provided at a top end thereof, further comprising: The top end of the threaded compression bar is provided with a spanner bar, and the threaded compression bar is in threaded connection with the through column through threads of the outer wall; The bottom of the T-shaped sliding block is provided with a semi-arc pressing plate, and the T-shaped sliding block is movably connected with the threaded compression bar; The positioning column is used for sleeving the sleeve, a shape correction arc plate is arranged on the positioning column opposite to the semi-arc pressing plate, and the positioning column is positioned at the middle section of the support; and the gland is connected to the positioning column through a bolt. Preferably, guide posts are arranged on two sides of the support, through holes are formed in two ends of the T-shaped sliding block, and the through holes are in sliding connection with the guide posts. Preferably, the gland is replaceable with a clamping assembly, and the structure of the clamping assembly includes: The middle section of the adjusting rod is sequentially provided with a forward thread section, a non-thread section and a reverse thread section, and one end of the adjusting rod is arranged on the support through a bearing; The clamping half-arc block is provided with threaded through holes, two groups of clamping half-arc blocks are symmetrically arranged on the unthreaded section of the adjusting rod, and the threaded through holes of the clamping half-arc block are in threaded connection with the matched forward-rotation threaded section or reverse-rotation threaded section. Preferably, the T-shaped sliding block is movably connected with the threaded compression bar in a mode that an inward concave sliding groove is formed in the top end of the T-shaped sliding block, an outward convex disc is arranged at the bottom end of the threaded compression bar, and the disc is in sliding connection with the sliding groove. The utility model at least comprises the following beneficial effects: the device drives the semi-arc pressing plate on the T-shaped sliding block to realize up-down expansion by rotating the threaded pressing rod, and is matched with the shape correction arc plate on the positioning column to realize the restoration of the concave punching mark on the sleeve by extruding in the up-down direction, so that the operation is simple and convenient, the efficiency is high, the restoration of 1 piece takes about 30 seconds, and the production efficiency is effectively improved; The device is directly sleeved on the positioning column by the sleeve to be repaired, is fixed by the gland, is fast to install and position, is tightly pressed by the shape correction arc plate, has small uniform stress, has no knocking trace on the surface, is attractive in repair and has low rejection rate. Additional advantages, objects, and features of the utility model will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the utility model.
