Description
Technical field
The utility model relates to carbide alloy axle sleeve fixing technical field, particularly a kind of fixture of novel fixing carbide alloy axle sleeve.
Background technology
Axle sleeve refers to the sleeve on propeller shaft or stern tube shaft.And bearing (Japan's person " axle is subject to ") plays parts that are fixing and reduction load coefficient of friction in mechanical transmission course.Axle sleeve generally plays sliding bearing effect.In order to save the wall thickness of the axial load design axle sleeve that material needs according to bearing, usually select cast copper or carbide alloy material.Axle sleeve can not bear axial load, maybe can only bear less axial load.
Axle sleeve is owing to matching with axle, therefore, the endoporus of axle sleeve is needed to carry out polishing, to reduce the roughness value of axle sleeve inner surface, before processing, first the pressing plate of axle sleeve with two band V-shaped grooves is clamped, carry out artificial polishing or machine polishing again, but, for carbide alloy axle sleeve, because its mechanical strength is than the height several times of other material axle sleeve, therefore, can produce higher cutting force in polishing process acts on carbide alloy axle sleeve, cutting force is far above the chucking power of two pressing plates, cause realizing the fixing of axle sleeve, finally result in the increase of carbide alloy surface of inner hole of shaft sleeve roughness.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of compact conformation, effectively prevents the fixture that carbide alloy boss failure, clamping carbide alloy axle sleeve are firm, can ensure the novel fixing carbide alloy axle sleeve that polishing precision is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of fixture of novel fixing carbide alloy axle sleeve, it comprises grip block, threaded rod, pressing plate and oil cylinder, the top of described grip block is provided with V-shaped groove I, the top of grip block is also provided with screwed hole and groove, screwed hole and groove are separately positioned on the both sides of V-shaped groove I, one end of described threaded rod is threaded with screwed hole, described oil cylinder perpendicular to grip block bottom and be fixedly mounted in groove, described pressing plate is provided with the opposed V-shaped groove II with V-shaped groove I, one end of pressing plate is hinged on the other end of threaded rod, the other end of pressing plate is hinged on the piston rod of oil cylinder, V-shaped groove II be arranged on pressing plate and threaded rod hinged place and between pressing plate and the hinged place of cylinder piston rod, described V-shaped groove I and the surface of V-shaped groove II are provided with rubber blanket.
It also comprises controller, and described controller is connected with oil cylinder.
Described controller is arranged on the sidewall of grip block.
The groove depth of described V-shaped groove I is greater than V-shaped groove II.
The utility model has the following advantages: the surface of (1) V-shaped groove I of the present utility model and V-shaped groove II is provided with rubber blanket, rubber blanket can not only effectively prevent weighing wounded of carbide alloy sleeve outer surface, and the frictional force with carbide alloy axle sleeve can also be increased, the folder that effectively prevent carbide alloy sleeve outer surface damages.(2) when the piston rod of oil cylinder of the present utility model is in retracted mode, and the hydraulic coupling that oil cylinder provides is much larger than the cutting force produced in polishing, thus make the V-shaped groove II on pressing plate tightly be pressed on carbide alloy axle sleeve, therefore, in polishing process, effectively prevent carbide alloy axle sleeve from getting loose, ensure that the surface roughness of the endoporus of carbide alloy axle sleeve, ensure that polishing precision.
Accompanying drawing explanation

Fig. 2 is operating diagram of the present utility model;
In figure, 1-grip block, 2-threaded rod, 3-pressing plate, 4-oil cylinder, 5-V shape groove I, 6-screwed hole, 7-groove, 8-V-shaped groove II.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1 or 2, a kind of fixture of novel fixing carbide alloy axle sleeve, it comprises grip block 1, threaded rod 2, pressing plate 3 and oil cylinder 4, the top of described grip block 1 is provided with V-shaped groove I5, the top of grip block 1 is also provided with screwed hole 6 and groove 7, screwed hole 6 and groove 7 are separately positioned on the both sides of V-shaped groove I5, one end of described threaded rod 2 is threaded with screwed hole 6, described oil cylinder 4 perpendicular to grip block 1 bottom and be fixedly mounted in groove 7, described pressing plate 3 is provided with V-shaped groove I5 opposed V-shaped groove II8, one end of pressing plate 3 is hinged on the other end of threaded rod 2, the other end of pressing plate 3 is hinged on the piston rod of oil cylinder 4, V-shaped groove II8 is arranged between the hinged place of pressing plate 3 and threaded rod 2 and the hinged place of pressing plate 3 and oil cylinder 4 piston rod, when the piston rod controlling oil cylinder 4 is retracted, oil cylinder 4 makes the V-shaped groove II8 on pressing plate 3 be pressed on carbide alloy, in polishing process, effectively prevent carbide alloy axle sleeve from getting loose, ensure that the surface roughness of the endoporus of carbide alloy axle sleeve.The groove depth of described V-shaped groove I5 is greater than V-shaped groove II8, and the surface of V-shaped groove I5 and V-shaped groove II8 is provided with rubber blanket, and rubber blanket can not only effectively prevent weighing wounded of carbide alloy sleeve outer surface, and can also increase the frictional force with carbide alloy axle sleeve.
