Technical field
The present invention relates to the parts on a kind of lathe, especially refer to a kind of cooling sealing device of rotary guide sleeve.
Background technology
Modern mechanical industrial expansion is more and more higher to the requirement on machining accuracy of lathe. With regard to high-precision numerical control lathe, its major advantage is high rotating speed, high accuracy, fast cutting speed. Main shaft and guide pin bushing are the vitals of lathe, concerning high-speed precise machine tool, its machining accuracy depends on the precision of main shaft and guide pin bushing system to a great extent, but in the time of lathe entry into service, the rolling element of bearing turns round in raceway, be subject to frictional force and can produce heat, make the temperature rise of bearing. In high rotation speed operation situation, caloric value is just larger for a long time, and the phase mutual friction while adding motion between other parts all can produce heat, causes axial region to heat up too high. Because the reason of expanding with heat and contract with cold, the precision of lathe is just subject to serious impact, the circular runout of guide pin bushing axial region and axial float are just larger, and handling ease produces the physical and mental health that the Relative Vibration between flutter, cutter and workpiece can make finished surface leave chatter mark, produce strong noise, has a strong impact on crudy and endanger operator; And all change because flutter makes to cut cross section, cutting angle, cutting force, when cutter is easy to wear, serious, can produce breakage. Due to the generation of cutting-vibration, in producing at present often to reduce cutting data, be cost such as reducing the depth of cut and reducing the speed of mainshaft, cause the service behaviour of lathe, cutter to be not in full use, limited the raising of machining production efficiency, this is undoubtedly huge loss concerning the manufacturing firm of batch production.
In the middle of Machinery Market with keen competition, high rotating speed, high-precision guide pin bushing becomes strong competition main points. Precision is high, has highly polishedly become necessarily requiring of client. For meeting the need of market, the requirement that vast same provisional capital adopts the sealing effectiveness that improves main shaft precision or improve guide pin bushing to improve product, and the sealing effectiveness that improves main shaft precision and guide pin bushing is difficult, study for many years to combine with practical effect and developed through my company and directly drive guide pin bushing by main shaft, guide pin bushing can do High Rotation Speed with main shaft, in the middle of High Rotation Speed, can produce heat, therefore develop oil cooling device and reduce heat, guarantee guide pin bushing is worked at normal temperatures. Driving claw formula rotary guide sleeve oil cooling sealing device can well meet client's requirement.
