Description
Technical Field
The invention relates to the technical field of molding and trimming of die castings, in particular to a polishing and trimming device for post-molding treatment of a die-casting end cover of a generator.
Background
The generator is a mechanical device for converting mechanical energy into electric energy, and is driven by a water turbine, a steam turbine, a diesel engine or other power machines, so that energy generated by water flow, air flow, fuel combustion or nuclear fission is converted into mechanical energy to be transmitted to the generator, and then the mechanical energy is converted into electric energy by the generator. Structurally, a generator is generally composed of a stator, a rotor, an end cover, a bearing, and the like.
The miniature asynchronous generator generally adopts a cast iron end cover with a bearing, and a bearing chamber for accommodating the bearing and a spigot matched with the stand are arranged on the end cover. The end cover plays roles of supporting the rotating part, determining the relative position of the rotor and the stator, protecting the inside of the motor and guiding wind. The rigidity of the end cover structure, the dimensional accuracy and form and position tolerance of the spigot and the bearing chamber directly influence the uniformity of the air gap between the stator and the rotor and the quality level of the motor. Therefore, a key problem in end cap processing is how to control the accuracy of the spigot and bearing chamber, the coaxiality between the two, and the circular runout of the spigot step end face to the axis.
The bearing end cover is a connecting piece between the stator and the rotor, the accuracy of the motor air gap is ensured by means of the matching accuracy of the spigot and the bearing chamber, and the influence of loading and unloading abrasion on the accuracy is required to be small. Therefore, the requirements on the roughness of the spigot and the bearing chamber are high, and before the whole machine is assembled, special equipment is usually required to carry out precise finishing post-treatment on the die-cast bearing end cover.
Due to the special shape and processing position of the generator end cover, the following problems are inevitably caused when the generator end cover is trimmed by the existing device:
1. The trimming mode is single, the trimming processing of different processing parts is inconvenient, and the overall processing effect is not ideal. As described above, the bearing end cover has a plurality of machining portions, and the machining standards of different machining portions are different, specifically, the machining of the spigot should pay attention to the dimensional accuracy, cylindricity and roughness of the inner peripheral surface; the processing of the bearing chamber should pay attention to the roundness, roughness and coaxiality of the inner ring and the outer ring; the end face of the flange of the end cover is machined, the flatness and the circle run-out of the end face to the axis are noted, the existing device can only finish one part of the end cover of the bearing at one time due to single finishing function, and in the finishing treatment process of the end cover of the bearing, switching and transferring among a plurality of different machining devices are often needed, so that the time cost is increased, and the finishing effect is reduced.
2. The switching clamping inconvenience results in poor processing continuity. Specifically, when the bearing end cover is trimmed, the adopted machining mode and the selected clamping position are different, but the principle that a common clamping position is difficult to select and the common clamping mode is adopted to machine and clamp the bearing end cover is adopted, so that when the existing bearing end cover is trimmed, a method combining multiple clamping modes is generally adopted, and the bearing end cover is frequently disassembled and assembled according to the different machining positions in the machining process, so that the machining process is adapted, the overall duration of the trimming process is obviously prolonged, the machining efficiency is reduced, the continuity of the machining is damaged due to repeated disassembly and reassembly, and the trimming reference deviation and the trimming precision are easily caused.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
