Abstract
The utility model discloses a turbo-unit rotary shaft hatch grinding machine in the electric power system, which is composed of a rotary shaft 1, a grinding head 6 fixed on the rotary shaft, and two rotary shaft supporting brackets 2, 11; the two rotary shaft supporting brackets 2, 11 are cooperated with the internal diameter of the turbo-unit rotary shaft hatch, wherein, the grinding head is composed of a circular box shape grinding block bracket and a fan shape grinding block; the circumference of the circular box shape grinding block bracket is provided with an opening, and the part within the opening is provided with a plurality of fan shape spaces; the fan shape grinding block is freely positioned in the spaces of the grinding block bracket; one end of the rotary shaft is connected with a prime motor through a flexible shaft. When the prime motor drives the rotary shaft to rotate, the grinding block floats toward the circumference under the function of the centrifugal force to grind the inner wall of the shaft hatch.
Description
The utility model is a power system steam turbine engine group rotor axis hole sander.
When the making regular check on of Steam Turbine rotor, to carry out grinding process to the rotor shaft hatch inwall at the scene, make it neatly smooth, be convenient to inspections such as flaw detection, simultaneously in order to eliminate accident potential, also must bring out the corrosion of crackle easily and coarse defectives such as tool marks are carried out grinding process to shaft hole inner wall, having in the technology in the sixth of the twelve Earthly Branches, a kind of reliable and effective on-the-spot polishing means are not also arranged, is manually to polish with the stock that a head has husky cloth mostly, the polishing means are simple and crude, and efficient is low.
The purpose of this utility model provides a kind of sander of being convenient to The field.
Solution of the present utility model is as follows: this sander is made up of rotating shaft, bistrique and two shaft support framves that match with turbine rotor axis hole internal diameter of connecting firmly in rotating shaft, wherein bistrique by peripheral openings, in be divided into the round box shape abrading block frame in a plurality of fan-shaped spaces and the segmental abrasive block that freely is placed in the built on stilts lattice of abrading block is formed, an end of rotating shaft links by flexible axle and prime mover.
Sander is put into axis hole, two shaft support framves are positioned at the axis hole circle centre position with rotating shaft, and when the flexible axle of rotating shaft by the one end driven when rotating by prime mover, bistrique rotates with it, abrading block under action of centrifugal force to around float, shaft hole inner wall is polished.
Describe in detail according to embodiment below.
Fig. 1, the structure chart of sander.
Fig. 2, the A-A profile of Fig. 1.
Referring to Fig. 1, for disassembled for transport is put just, rotating shaft 1 can be divided into head, middle part and afterbody three joints, between three joints is thread connection, in the head rotating shaft, be provided with an adjustable shaft support frame 2, this bearing support has a circular base 3, this pedestal links by rolling bearing and head rotating shaft, on the circumference of pedestal 3, be provided with 3 120 ° of equally distributed Screw rod bearings pin 4, its fulcrum place is provided with the spring ball structure, also is provided with clamp nut 5 on the Screw rod bearings pin, after clamp nut is unscrewed, just the height of support foot can be regulated, the size of different shaft hole diameters can be adapted within the specific limits; Connected firmly bistrique 6 in the rotating shaft of middle part, bistrique is provided with 4 abrading blocks, and corresponding abrading block frame 7 is divided into 4 90 ° of fan-shaped spaces, and referring to Fig. 2, abrading block 8 freely is placed in the abrading block frame, and abrading block frame 7 connects firmly in the rotating shaft of middle part; The afterbody rotating shaft is provided with an axle sleeve 9, this axle sleeve links by two rolling bearings 10 and afterbody rotating shaft, the tail end of axle sleeve is with the splicing sleeve 11 that its external diameter matches with shaft hole diameter, when sander is put into axis hole, the supporting role of rotating shaft by its head rest supporting frame 2 and afterbody splicing sleeve 11 guaranteed the concentricity of it and axis hole, the power of prime mover is transferred to rotating shaft tail end 12 by flexible axle, plays the effect of soft polishing.
Use through overtesting and on-the-spot polishing, prove that this machine is reliable and effective on performance, it also has the advantage that the discrete parts combination is convenient to transport simultaneously.
