Description
Technical Field
The invention relates to the technical field of part grinding, in particular to a grinding device for processing parts of a gas generator set.
Background
The gas generator set consists of a gas engine, a generator, a control cabinet and other parts, wherein the gas engine and the generator are arranged on the same steel chassis. The unit takes combustible gases such as natural gas, well head associated gas, coal mine gas, water gas, refining tail gas, methane, coke oven gas, blast furnace gas and the like as fuels, and has the advantages of quick start and good economical efficiency.
The gas generator set is generally composed of thousands of parts, which are assembled together in sequence to jointly realize the function of the gas generator set. The gas generating set's part contains a circular ring shape part in the part, and this kind of part suit is on the rotor shaft of generator, mainly plays the rotation supporting role to the rotor shaft, and at the in-process of equipment, circular ring shape part is by fixed mounting in the circular recess that reserves on the generator shell.
However, since the annular part is obtained by casting, the end surface flatness and the circular degree of the outer circular surface of the finished product obtained by the rough machining method cannot meet the assembly requirement of the gas generator set with high precision, and if the cast annular part is directly put into use without being processed, the abrasion of the rotor shaft is aggravated, the service life of the rotor shaft is shortened, and the scrapping of the gas generator set is caused.
Therefore, the ring-shaped part obtained by rough machining needs to be subjected to finish machining, and the finish machining mainly comprises grinding machining of the opposite end faces and the outer circular face of the part.
The existing grinding method for the circular ring-shaped part is more conventional, the part is fixed on a processing table, and the grinding mechanism is used for respectively grinding two end surfaces and an outer circular surface of the part, and the processing method has the defects that:
1. when the opposite end faces of the circular ring-shaped part are machined, only one end face of the part can be ground at a time, and when the other end face of the part needs to be ground, the part needs to be detached from the machining table and clamped again. The two times of clamping and respectively processing not only increases unnecessary processing time and reduces processing efficiency, but also is difficult to ensure the consistency of the two times of clamping benchmarks, easily causes processing errors and improves the defective rate of finished products.
2. The two grinding processes of the end face and the outer circular face of the part are difficult to realize on the same device: on one hand, the grinding tools needed for grinding the end face and the outer circular face of the part are different; on the other hand, the two grinding processing modes have great difference, when the end face of the part is ground, the part needs to be fixed to enable the grinding cutter to rotate, and when the outer circular face of the part is ground, the cutter needs to be fixed to enable the whole part to rotate around the shaft, so that the existing grinding device cannot well coordinate the two grinding processing modes, and inconvenience is caused in the using process.
3. In the process of machining parts, a clamping mechanism is needed to clamp and fix the whole parts, the clamping mechanism adopted in the existing machining mode is often complex in structure, the degree of freedom of the parts in all directions can be completely limited, but the problem of excessive positioning is easily caused, the parts are inconvenient to disassemble and assemble, and even interference can be caused to the movement of a cutter or the parts in the grinding machining process.
4. Complicated mechanisms on the device often cause obstacles to manual feeding and discharging and clamping and mounting of parts, and are inconvenient to use.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
