Abstract
The utility model discloses a device for machining the inner side surface of a shaft shoe. The device comprises a base and a motor arranged on the base, wherein a limiting block is arranged on the base and provided with a containing space matched with the outer side surface of the shaft shoe, and a cutter is arranged at the front end of a rotating shaft of the motor; and when the motor is started, the rotating shaft drives the cutter to rotate, and the end of the cutter is matched to machine the inner side surface of the shaft shoe. The utility model aims at providing a device for machining the inner side surface of the shaft shoe, and through the implementation of the device, the machining accuracy and machining efficiency of the inner side surface of the shaft shoe can be improved, and the quality of products can be further ensured.
Description
Technical field
The utility model relates to a kind of bearing shell medial surface processing unit (plant).
Background technology
Bearing is one of critical component of steam turbine, under the lubrication and cooling effect of circulating lubricating oil, the turbine rotor that heavy duty is run up plays a supportive role, bearing shell is one of important building block of bearing, be the part that bearing directly contacts with rotating shaft, be shaped as the semi-cylindrical of watt shape, its effect is the active force that the carrying axle journal applies, keep oil film stable, bearing is worked reposefully and reduce the friction loss of bearing.The operation principle of bearing shell at first, needs to adopt exotic material to make bearing shell, so that bearing shell can be high temperature resistant so that bearing shell need to possess following characteristic; Secondly, the bearing shell medial surface need to be polished to smooth enough to reduce the frictional force between bearing shell and the rotating shaft as far as possible; At last, need to guarantee the radian of bearing shell medial surface.In the prior art, the bearing shell medial surface is processed main by mechanical means.Yet, because the particularity of bearing shell shape, lack a kind of frock that can process the bearing shell medial surface in the prior art, cause the machining accuracy of the medial surface of bearing shell not high, so that the medial surface smoothness of the bearing shell after the processing is inadequate, use thereby affect it, limit to a great extent the use of bearing shell and the quality of product, demand urgently improving.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of bearing shell medial surface processing unit (plant), and by enforcement of the present utility model, thereby machining accuracy and the working (machining) efficiency that can improve the bearing shell medial surface guarantee product quality.
For reaching this purpose, the utility model by the following technical solutions:
A kind of bearing shell medial surface processing unit (plant) comprises base, is installed in the motor on the described base, at described base limited block is set, and offers the spatial accommodation that cooperates with described bearing shell lateral surface on the described limited block, the rotating shaft front end mounting cutter of described motor;
When described electric motor starting, described rotating shaft drives described cutter and rotates, and makes described cutter end cooperate the medial surface of the described bearing shell of processing.
Also comprise baffle plate, fixing described base is used for the described bearing shell of axial restraint when described cutter rotates.
Described cutter two ends all arrange blade.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model is processed the medial surface of bearing shell by the cutter that adopts rotation, and the cutter two ends are equipped with blade, and working (machining) efficiency is high, simultaneously, the baffle plate of firm banking can guarantee that bearing shell can not be moved in processed process, thereby improves machining accuracy, guarantees product quality.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment 1:
Fig. 2 is part-structure schematic diagram among the utility model embodiment 1:
Wherein: 1, motor; 2, baffle plate; 3, limited block; 4, bearing shell; 41, lateral surface; 42, medial surface; 5, cutter; 6, rotating shaft; 7, base; 8, spatial accommodation.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
Propose a kind of bearing shell medial surface processing unit (plant), comprise base 7, be installed in the motor 1 on the base 7, at base 7 limited block 3 is set, offer the spatial accommodation 8 that cooperates with bearing shell 4 lateral surfaces 41 on the limited block 3, the rotating shaft 6 front end mounting cutters 5 of motor 1; Cutter 5 two ends all arrange blade, and bearing shell 4 is placed in the spatial accommodation 8, and when motor 1 startup, rotating shaft 6 band cutters 5 rapidly rotate, because the end of cutter 5 cooperates the medial surface 42 of processing bearing shell 4, the blade at cutter 5 two ends is to the medial surface 4 of bearing shell 4
2 process, and working (machining) efficiency is high, and simultaneously, the baffle plate 2 axial restraint bearing shells 4 of firm banking 7 prevent from causing bearing shell 4 to be subjected to displacement owing to the active force of 5 pairs of bearing shells 4 of cutter, cause bearing shell 4 damaged.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
Claims (3)
