The motor and the limiting block are movably connected with the base. The first pneumatic mechanism and the second pneumatic mechanism are fixedly connected with the base. A connecting rod of the first pneumatic mechanism is flexibly connected with the limiting block. A connecting rod of the second pneumatic mechanism is flexibly connected with the motor. A cutting tool is installed at the front end of a spindle of the motor. A containing space which is matched with the outer lateral side of a bearing pad is arranged on the limiting block. The numerical system is in control connection with the first pneumatic mechanism, the second pneumatic mechanism and the motor. When the motor is started, the spindle drives the cutting tool to rotate and the end portion of the cutting tool machines the inner lateral side of the bearing pad to be machined in a matched mode. Due to the bearing pad automatic machining device, automatic machining of the inner lateral side of the bearing pad can be conducted, meanwhile machining precision and machining efficiency of the inner lateral side of the bearing pad are improved, and therefore product quality is ensured.

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
Problem for the prior art existence, the purpose of this utility model is to propose a kind of automatic processing device of bearing shell, by enforcement of the present utility model, can realize the bearing shell medial surface is implemented automation processing, simultaneously, thus can improve the machining accuracy of bearing shell medial surface and working (machining) efficiency guarantees product quality.
For reaching this purpose, the utility model by the following technical solutions:
A kind of automatic processing device of bearing shell, comprise base, motor, limited block, the first pneumatic mechanism, the second pneumatic mechanism and digital control system, described motor and described limited block are flexibly connected described base, described the first pneumatic mechanism is fixedly connected with described base with described the second pneumatic mechanism, the described limited block of the flexible connection of the connecting rod of described the first pneumatic mechanism, the described motor of the flexible connection of the connecting rod of described the second pneumatic mechanism, the rotating shaft front end mounting cutter of described motor, offer the spatial accommodation that cooperates with described bearing shell lateral surface on the described limited block, described the first pneumatic mechanism of described digital control system control connection, described the second pneumatic mechanism, 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 cutter of the utility model by adopting rotation carries out automation processing to the medial surface of bearing shell, 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.
