Description
Technical Field
The utility model relates to a clamping instrument, concretely relates to clamping instrument is used in processing of large-scale hydroelectric generating set axle class.
Background
When large-scale hydroelectric machine shafts are machined, due to the fact that the large-scale hydroelectric machine shafts are large in size, clamping is not easy to carry out mostly, and some clamping devices are tools with customized sizes, are poor in adaptability, cannot adapt to clamping of shafts with different sizes, and are poor in using effect.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model adopts the following technical scheme:
the utility model provides a clamping instrument is used in processing of large-scale hydroelectric generating set axle type, includes the bottom plate, the bottom plate inboard is formed with protruding eaves of annular, straining device, be provided with the fastening bolt who is used for pressing from both sides the tight axle type outside on the protruding eaves of annular, straining device includes central box, be provided with the worm in the central box, central box is provided with the tensioning box all around, be provided with the worm wheel that corresponds with the worm in the tensioning box, be fixed with the tensioner arm on the rotation axis of worm wheel, the outside of bottom plate is provided with the centre gripping barrel, the rear end of worm just stretches into in the centre gripping barrel with bottom plate threaded connection, the rear end of worm is provided with screws up the head.
As a further explanation, the tightening head is provided with a hexagon socket, which facilitates better rotation of the worm, and further better opens the tensioning mechanism to support the inside of the shaft.
As further explained, the front section of the central box body is of a closed structure, and a hinged plate corresponding to the worm is arranged in the central box body, so that the worm can be fixed better.
As further explained, the fastening bolts are uniformly arranged along the periphery of the annular convex eaves, so that the fastening bolts can be better clamped and fixed with the shaft outside.
Compared with the prior art, the utility model, have following advantage: the utility model discloses simple structure, can be fine carry out the centre gripping to large-scale hydroelectric generating set axle class fixed, adaptation not unidimensional axle class that moreover can be fine, excellent in use effect.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic view of the arrangement structure of the fastening bolt of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention.
Example (b): as shown in fig. 1-2, a clamping tool for processing shafts of a large hydroelectric generating set comprises a base plate 1, an annular convex brim 2 and a tensioning mechanism 3 are formed on the inner side of the base plate 1, a fastening bolt 4 used for clamping the outer side of the shafts is arranged on the annular convex brim 2, the tensioning mechanism 3 comprises a central box body 301, a worm 302 is arranged in the central box body 301, a tensioning box body 303 is arranged around the central box body 301, a worm wheel 304 corresponding to the worm 302 is arranged in the tensioning box body 303, a tensioning arm 305 is fixed on a rotating shaft of the worm wheel 304, a clamping cylinder body 5 is arranged on the outer side of the base plate 1, the rear end of the worm 302 is in threaded connection with the base plate 1 and extends into the clamping cylinder body 5, and a tightening head 6 is arranged at the rear end of the worm 302. The tightening head 6 is provided with an inner hexagonal hole 601, so that the worm can be rotated better, and the tensioning mechanism can be better expanded to support the inside of the shaft. The front section of the central box body 301 is of a closed structure, and a hinge plate 306 corresponding to the worm 302 is arranged in the central box body 301, so that the worm can be fixed better. Fastening bolts 4 are evenly arranged along the periphery of the annular convex eaves 2, and are favorable for better clamping and fixing with the outside of the shaft.
During the specific use, with bottom plate and axle bottom butt, then rotate the worm with the hexagonal instrument in, the worm drives the worm wheel rotatory to drive the tensioning arm and open the tight axle hole inner wall of card, screw up fastening bolt simultaneously and fix axle type outside, centre gripping barrel 5 is fixed with three-jaw chuck centre gripping, can follow the outside and press from both sides tight centre gripping barrel, also can follow inboard tensioning, and it is more convenient to use.
This embodiment simple structure, can be fine carry out the centre gripping to large-scale hydroelectric generating set axle class fixed, adaptation not unidimensional axle class that moreover can be fine, excellent in use effect.
The present invention is illustrated by way of example and not by way of limitation. It will be apparent to those skilled in the art that other variations and modifications of the present invention can be made in light of the above teachings, and it is not necessary or necessary to exhaustively enumerate all embodiments herein, and it is intended that all such obvious variations and modifications are within the scope of the present invention.
