Abstract
A runner plate grinder comprises a support, wherein at least three lifting jacks are mounted on the support. The lifting jacks are arranged on the edge of a runner plate in a supporting mode and are evenly distributed along the edge of the runner plate. A power device which drives a rotating shaft to rotate is further arranged on the support. A cantilever is horizontally mounted on the rotating shaft and provided with at least three arm bodies, and a grinding disk is mounted on the side, corresponding to the runner plate, of each arm body. The runner plate grinder is simple in structure and good in grinding effect, and greatly saves time used for grinding and polishing of the runner plate.
Description
Technical field:
The utility model relates to a kind of runner plate grinder, is applicable to that hydraulic generator mirror plate grinds.
Background technology:
Runner plate is the important workpiece of hydrogenerator, and its machining accuracy and surface roughness require all very high, require runner plate parallelism of two planes≤0.02-0.04mm; Runner plate flatness≤0.02-0.04mm; The surface roughness of working face is≤0.2-0.4 μ m.After the operation that hydraulic generator mirror plate (is generally 8-10) through after a while, because the runner plate working face is long-term and the thrust bearing shoe valve friction, can cause the surfaces of mirror plate roughness to raise, thereby cause the rising of thrust bearing shoe valve temperature, acceleration thrust bearing shoe valve wearing and tearing are when serious even can influence the safe operation of unit.Therefore when each major overhaul, the situation of surfaces of mirror plate is checked in the capital, whether the situation decision according to surfaces of mirror plate grinds runner plate, but existing grinding generally all is need send to factory to grind very trouble, and simple grinder does not reach the grinding requirement.
The utility model content:
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, grinding effect good, save runner plate greatly grinds runner plate grinder with service time of polishing.
For achieving the above object, the technical scheme of employing is:
A kind of runner plate grinder, comprise support, at least three jack are installed on the described support, described jack is supported on the edge of runner plate and evenly arranges along the edge of described runner plate, also be provided with the power set of driven rotary axle rotation on the described support, the cantilever that level is laid is installed on the described rotating shaft, and described cantilever is provided with at least three arm bodies, and a side of corresponding described runner plate is equipped with abrasive disk on described each arm body.
Described abrasive disk is installed on the described arm body by adjusting device, and described abrasive disk can be regulated its position on described arm body by adjusting device.
The top of described jack is provided with disk with the end face that described runner plate contacts.
A plurality of described abrasive disks are whole on described runner plate to be arranged for misplacing.
Owing to adopt said structure, the utlity model has following advantage:
1, for the support of runner plate, adopt three jack to support, single jack all can be regulated respectively, and the level of being convenient to runner plate is regulated, and with the wooden disk of making of hard, enlarges supporting surface with the protection runner plate on jack.
2, bistrique has carried out the dislocation layout, can both be ground to guarantee the runner plate face, prevents to grind the dead band.
In sum, this apparatus structure is simple, grinding effect good, save runner plate greatly grinds and the service time of polishing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
The specific embodiment:
Below in conjunction with accompanying drawing, further describe the specific embodiment of this patent.
As shown in Figure 1, 2.This device comprises support 1, the jack 2 of three 5t levels is installed on the described support 1, described jack 2 is supported on the edge of runner plate 3 and evenly arranges along the edge of described runner plate 3, also be provided with the power set of driven rotary axle rotation on the described support 1, described power set comprise motor 8 and the reductor 7 that is connected with motor, the cantilever 5 that level is laid is installed on the described rotating shaft, rotating shaft and cantilever 5 are connected by spline, described cantilever 5 is provided with three arm bodies 10, a side of corresponding described runner plate is equipped with abrasive disk 4 on described each arm body 10, rotating shaft drives the rotation of grinder cantilever by splined shaft makes abrasive disk 4 produce rotation and revolution on the runner plate face, thereby realizes grinding and polishing to runner plate.
Described abrasive disk 4 is installed on the described arm body by adjusting device 6, and described abrasive disk 4 can be regulated its position on described arm body 10 by adjusting device 6.
The top of described jack 2 is provided with disk 9 with the end face that described runner plate 3 contacts, and disk 9 adopts the wooden making of hard, and diameter 300mm enlarges supporting surface with protection runner plate 3.
A plurality of described abrasive disks 3 are whole on described runner plate to be arranged for misplacing.
Regulate the height of cantilever 5 if desired, can be by on splined shaft, being inserted in one section hollow shaft sleeve in order to regulate the height of cantilever, to satisfy the needs that the different-thickness runner plate grinds.
