When the tool is used, the tool is laterally placed into the magnetic pole key groove, the arc-shaped plate is extruded through the key groove, the file on the front face of the fixing plate is tightly attached to the side wall of the key groove through spring force, and the tool is made to slide along the key groove to remove high points generated in the key groove. The tool has the advantages of simple structure, quickness in manufacturing, convenience in operation and high treatment efficiency, and is suitable for strain treatment of the magnetic pole key keyways of the rotors of various hydroelectric generating sets.
Description
Technical Field
The utility model belongs to generator frock field, concretely relates to simple and easy hydraulic generator magnetic pole key keyway strain handles frock.
Background
The magnetic pole key is required to be pulled out to process the magnetic pole or pull out the magnetic pole key for inspection in the installation and maintenance processes of the hydraulic generator set, the magnetic pole key groove is easily damaged in the key pulling process, and the subsequent installation of the magnetic pole key and the normal operation of the hydraulic generator are influenced due to the protruding high point in the magnetic pole key groove. Because general keyway is narrower, and length is long moreover, general electronic multiplexer utensil can't use, and the special broach preparation cycle of keyway is longer, influences hydraulic generator's normal work.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a simple structure, preparation are swift, convenient operation, processing are high-efficient is provided to be applicable to the simple and easy hydraulic generator magnetic pole key keyway strain processing frock that various hydroelectric set rotor magnetic pole key keyway strain was handled.
In order to solve the technical problem, the utility model discloses a technical scheme is: a simple hydro-generator magnetic pole key keyway strain treatment tool comprises a fixed plate, wherein a file is arranged on the front surface of the fixed plate, an arc-shaped plate is arranged on the back surface of the fixed plate, and a spring is arranged between the concave surface of the arc-shaped plate and the back surface of the fixed plate; the file connecting plates are arranged at the two ends of the file, and the file connecting plates, the fixed plate and the arc-shaped plate are fixed through connecting countersunk bolts. When the tool is used, the tool is laterally placed into the key groove of the magnetic pole key, the arc-shaped plate is extruded through the key groove, the file on the front face of the fixing plate is tightly attached to the side wall of the key groove through the elastic force of the spring, and then the tool slides along the key groove to remove high points generated by strain in the key groove; the fixing mode of the file is convenient to replace the file when the file cannot meet the working requirement due to abrasion.
Furthermore, an adjusting gasket is arranged between the file and the fixing plate, the tool can treat the damage of various different degrees in the key groove by adjusting the thickness of the gasket, and the tool can be suitable for rotor magnetic pole key grooves of water turbine generator sets of various models.
Furthermore, the side welding of fixed plate has the connecting rod, makes things convenient for the manual work to make the frock reciprocate, gets rid of the high point that the keyway strains.
Compared with the prior art, the utility model has the advantages that: the structure is simple, the operation is easy, the treatment efficiency is high, the device can be repeatedly used for a long time, and the device can be suitable for treating the strain of the magnetic pole key groove of each type of hydraulic generator rotor.
Drawings
Fig. 1 is a side view of the present invention.
Fig. 2 is a plan view of the present invention.
In the figure, 1 is a file connecting plate, 2 is a file, 3 is an arc-shaped plate, 4 is a spring, 5 is a connecting countersunk bolt, and 6 is a fixing plate.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the simple hydro-generator pole key keyway strain treatment tool comprises a fixing plate 6, wherein a file 2 is arranged on the front surface of the fixing plate 6, an arc-shaped plate 3 is arranged on the back surface of the fixing plate 6, and a spring 4 is arranged between the concave surface of the arc-shaped plate 3 and the back surface of the fixing plate. The file 2 has file connecting plates 1 at both ends, and the file connecting plates 1, the fixing plate 6 and the arc plate 3 are fixed by connecting countersunk bolts 5. An adjusting gasket is arranged between the file 2 and the fixing plate. The welding of fixed plate 6 side has the connecting rod (the connecting rod does not mark in the attached drawing, in order not to influence this device overall view show, nevertheless does not influence understanding the utility model discloses technical scheme).
During the specific use, at first use keyway measuring tool to measure the minimum thickness of keyway, according to the measured value, through the adjusting shim thickness between adjustment file and the fixed plate, make the whole thickness of frock be greater than about 0.20mm of the minimum thickness of keyway, make things convenient for the file laminating keyway side. The tool with the adjusted thickness is laterally placed into the magnetic pole key groove, the arc-shaped plate is extruded through the key groove, and the file on the front face of the fixing plate is tightly attached to the side wall of the key groove through the elastic force of the spring. And welding a connecting rod on the tool, manually moving the tool up and down in the key slot, and removing the high point of the key slot strain. Due to the different damage degree of the pulled wound part and the abrasion of the file, the thickness of the adjusting shim between the file and the fixing plate should be gradually increased during the operation until all the high points are removed.
When the higher keyway of horizontal position need be handled to the frock, can carry out further improvement to the frock, set up the screw hole in the side of frock fixed plate 6, use the connecting rod of different length, connecting rod one end be equipped with the side screw hole complex screw of frock fixed plate 6, according to the processing position of different level, select to change the connecting rod of suitable length, make the frock satisfy the keyway and handle the needs. The connecting rod can be further improved, the connecting rod adopts a two-section design, the connecting rod adopts a hollow tube and comprises an inner tube and an outer tube, the outer tube is sleeved on the inner tube, the outer tube and the inner tube can slide relatively, and threads matched with the threads on the side surface of the fixing plate 6 are arranged at one end of the inner tube connected with the fixing plate 6. The side wall of the inner pipe is provided with a fixing screw, and the fixing and moving relation between the inner pipe and the outer pipe is changed by rotating the fixing screw. When the connecting rod is used, the screw is screwed outwards to fix the inner pipe and the outer pipe to slide, so that the length of the connecting rod is changed. Adjusting the connecting rod to a proper length, internally screwing a fixing screw, fixing the inner pipe and the outer pipe to fix the length of the connecting rod, and then finishing the key groove strain treatment.
