But this clamping device quick assembly disassembly increases and compresses tightly the area, simple structure, and convenient operation can press from both sides tight magnetic pole adjustment gasket high-efficiently, safely.
Description
Technical Field
The utility model belongs to the field of large-scale hydraulic generator equipment, and particularly relates to a rapid clamping device for a magnetic pole adjusting gasket of a large-scale hydraulic generator.
Background
After the rotor magnetic yoke stacking work of the large-scale water turbine generator set is completed, gaskets with different thicknesses are matched with contact positions of two sides of a dovetail groove of the magnetic yoke and the magnetic poles according to the roundness measurement condition of the magnetic yoke, the gaskets are spot-welded on the surface of the magnetic yoke, and the spot-welded part begins to hang the magnetic poles after being polished to be flat.
The conventional method of operation is as follows: one method is to use a magnetic pole reshaping tool to compress the adjusting gasket, and in the method, the reshaping tool needs to be moved along the magnet yoke dovetail groove to be taken out from the top when the method is disassembled, so that the disassembly and the assembly are difficult, time-consuming and labor-consuming; the other method is to use a C-shaped clamp to press the adjusting gasket, and the method has the defects that the contact area of the C-shaped clamp and the adjusting gasket is small, so that the pressing force is insufficient, high points can be generated locally after the gasket is subjected to spot welding, the contact area of a magnetic pole and a magnetic yoke is influenced, and even the whole roundness and the verticality of the rotor are not met.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a rapid clamping device for a magnetic pole adjusting gasket of a large-scale hydraulic generator, which can be rapidly assembled and disassembled, increases the pressing area, has a simple structure and convenient operation, and can efficiently and safely clamp the magnetic pole adjusting gasket.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a large-scale hydraulic generator magnetic pole adjustment gasket quick clamping device, includes the screw rod, and the screw rod lower extreme is equipped with the bottom plate, and the bottom plate card is gone into the dovetail groove of yoke, and the adjustment gasket upside is equipped with the clamp plate, is equipped with the through-hole that supplies the screw rod to pass on the clamp plate, is equipped with on the screw rod to carry out the lock nut who compresses tightly to the clamp plate.
In a preferred scheme, an elastic device is arranged at the bottom of the pressing plate.
In a preferred scheme, the elastic device is a rubber sleeve, and the rubber sleeve is sleeved at the end part of the pressing plate.
In a preferred scheme, the bottom plate is provided with a threaded hole matched with the screw rod.
According to the rapid clamping device for the magnetic pole adjusting gasket of the large-scale hydraulic generator, provided by the utility model, the fastening principle of the nut is utilized, and the fastening force of the bolt is transmitted to the pressing plate 5 by screwing the locking nut, so that the adjusting gasket is pressed by the pressing plate. Utilize the structural feature of yoke, clamp the bottom plate in the dovetail groove, can make the clamp plate atress compress tightly the adjusting shim through screwing up lock nut, it is convenient to dismantle, can easily take out from yoke dovetail groove with the device rotation 90 during the dismantlement, and the device principle is simple, has stronger practicality and reliability.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a schematic view of the overall structure of the present invention;
in the figure: the magnetic iron comprises a screw rod 1, a bottom plate 2, a magnetic yoke 3, an adjusting gasket 4, a pressing plate 5, a locking nut 6 and an elastic device 7.
Detailed Description
As shown in fig. 1, a quick clamping device of large-scale hydraulic generator magnetic pole adjusting shim, including screw rod 1, 1 lower extreme of screw rod is equipped with bottom plate 2, the length of bottom plate 2 is greater than the width of the entry of the dovetail groove of yoke 3, the width of bottom plate 2 is less than the width in the entry of the dovetail groove of yoke 3, bottom plate 2 card is gone into in the dovetail groove of yoke 3, 4 upsides of adjusting shim are equipped with clamp plate 5, be equipped with the through-hole that supplies screw rod 1 to pass on the clamp plate 5, be equipped with lock nut 6 that compresses tightly clamp plate 5 on the screw rod 1.
When a magnetic pole adjusting gasket is installed on a rotor of the hydraulic generator, firstly, the screw rod 1 and the bottom plate 2 are placed into the dovetail groove of the magnetic yoke 3, the bottom plate 2 is placed into the dovetail groove, the bottom plate 2 is longitudinally arranged and is placed to the bottom of the dovetail groove of the magnetic yoke 3, and then the bottom plate 2 is rotated by 90 degrees to clamp the bottom plate 2 in the dovetail groove; secondly, a pressure plate 5 penetrates into the screw rod 1 and then a locking nut 6 is installed; finally, the stress of the locking nut 6 is adjusted according to the requirement, so that the pressure plate 5 compresses the adjusting gasket 4, and when the required compression requirement is met, the locking nut 6 can be stopped being screwed; during the dismantlement, loosen lock nut 6, take off clamp plate 5, can easily take out from yoke dovetail groove with bottom plate 2 rotation 90.
Preferably, the bottom of the pressure plate 5 is provided with an elastic device 7. The elastic device 7 can be a rubber pad which is glued at the bottom of the pressing plate 5. The elastic means 7 prevents the spacer 4 from being damaged during clamping.
Preferably, the elastic device 7 is a rubber sleeve, and the rubber sleeve is sleeved at the end part of the pressure plate 5. The elastic device 7 is arranged as a rubber sleeve, so that the elastic device 7 is convenient to replace.
Preferably, the bottom plate 2 is provided with a threaded hole matched with the screw rod 1. Thereby realizing the detachable connection of the bottom plate 2 and the screw 1.
The device utilizes the fastening principle of nuts, and transmits bolt fastening force to the pressing plate 5 by screwing the locking nut 6, so that the pressing plate 5 compresses the adjusting gasket 4. Can make clamp plate 5 atress compress tightly adjusting shim 4 through screwing up lock nut 6, it is convenient to dismantle, can easily take out from yoke dovetail groove with the device rotation 90 during the dismantlement, and the device principle is simple, has stronger practicality and reliability.
