Abstract
The invention relates to a device for suppressing the vibration of a milling machine cutter main shaft. The device comprises a milling machine chassis housing, a milling machine cutter main shaft and a radial containment extrusion film gas static pressure bearing, wherein the radial containment extrusion film gas static pressure bearing is installed on the milling machine cutter main shaft of the milling machine chassis housing, and is sleeved on the output end of the milling machine cutter main shaft. The device has the beneficial effects that the vibration problem of the main shaft can be effectively solved, the machining error caused by the vibration of the main shaft is greatly reduced, the machining precision is improved, and the requirement of the modern advanced machining technology can be met; compressed air does not need to be provided by outside; the structure is small and simple, and the device is directly fixed on a machine tool through a tightening bolt and a fixing screw; and the non-contact, the low abrasion and the low noise can be realized.
Description
Technical field
The invention belongs to the machine tool technology field, relate in particular to the device that suppresses the vibration of milling machine cutter spindle.
Background technology
The Milling Process technology is one of most crucial technology of metal cutting process technology, and the countries in the world machinery manufacturing industry extensively adopts advanced Milling Process technology, to improve manufacture level and to the adaptive faculty and the competitiveness in dynamic changeable market.The deficiency of existing Milling Process technology is the vibration of cutter in process, and it has reduced the workpiece machining surface quality; Having quickened the wearing and tearing of cutter and machine part, caused cutwork normally not carry out when serious, therefore reduced the vibration cutting in the process, is a technical problem of this area.
Summary of the invention
The purpose of this invention is to provide a kind of device that suppresses the vibration of milling machine cutter spindle.
Thinking of the present invention is: utilize the gas viscosity damping characteristic that radially contains the squeeze film aerostatic bearing in the ultrasonic vibration extrusion technique to suppress vibration.
Technical scheme of the present invention is: a kind of device that suppresses the vibration of milling machine cutter spindle, comprise the milling machine casing, milling machine cutter spindle and radially contain the squeeze film aerostatic bearing, radially contain the squeeze film aerostatic bearing and comprise piezoelectric patches, inner sleeve, trip bolt and outer sleeve, inner sleeve and piezoelectric patches are combined into PZT (piezoelectric transducer), PZT (piezoelectric transducer) is evenly distributed on the inner sleeve excircle by three groups of piezoelectric patches to be formed, interval 120 degree between every group of piezoelectric patches, outer sleeve is sleeved on outside the inner sleeve, with trip bolt inner sleeve is fastened on the outer sleeve, the device that it is characterized in that the vibration of described inhibition milling machine cutter spindle is to be installed in the milling machine cutter spindle place of milling machine casing with radially containing the squeeze film aerostatic bearing, radially contains on the output that the squeeze film aerostatic bearing is sleeved on the milling machine cutter spindle.
A kind of device that suppresses the vibration of milling machine cutter spindle of the present invention is characterized in that described outer sleeve one end that radially contains the squeeze film aerostatic bearing has axle sleeve, and axle sleeve is sleeved on the milling machine casing of milling machine cutter spindle, is screwed.
A kind of device that suppresses the vibration of milling machine cutter spindle of the present invention is characterized in that described hold-down screw and the fastening bolt on the axle sleeve wall that is included in the axle sleeve bottom that be screwed.
Principle of the present invention is: piezo-electric crystal produces the periodical high-frequency vibration under the alternating voltage effect, gas in the air gap is carried out the periodicity extruding, because the effect of gas viscosity forms the damping air film, thereby produce damping force inhibition spindle vibration and main shaft is not had the machinery wearing and tearing according to the main shaft of damping characteristic to vibration.
The invention has the beneficial effects as follows:
1, efficiently solves the spindle vibration problem, reduced the mismachining tolerance that produces by spindle vibration greatly, improved the requirement that machining accuracy satisfies modern advanced machining technology;
2, do not need the external world that Compressed Gas is provided,
3, structure is small and exquisite simple, with fastening bolt and hold-down screw it directly is fixed on the lathe to get final product;
4, noncontact, low wearing and tearing, low noise.
