Description
The utility model relates to a kind of aperture distance, elongated hole fine boring machine, belongs to metal cutting process equipment field.
Existing porous series, aperture adopt the multiaxis of single shaft processing or roller bearings to process apart from accurate boring mostly, and the former production efficiency is low, and the latter is limited by rigidity and pitch-row.There is the problem of boring bar poor rigidity and toolsetting difficulty in the processing of elongated hole.Domestic horizontal fineboring machine workbench chip space is very little, makes to adopt big flow to spray cooling cleaning difficulty; Any conversion of hydraulic system speed is not easy to realize that the fuel tank heating is bigger, and fast forward speed is not high.
The objective of the invention is to overcome the deficiency of prior art, and a kind of aperture distance, elongated hole fine boring machine are provided.
The utility model is achieved in that this boring machine combines fuel tank 1, lathe bed 2, electrical system 3, outer cover 4, pipe-line system 5, boring bar 6, boring head 7, anchor clamps 8 and static pressure fuel tank 9 by known method.Wherein, the support part of the main shaft 10 of boring head 7 is one by directly being embedded in hydrodynamic and hydrostatic pressure bearing on the main shaft 10 shell spares or hydrostatic bearing 11 and flow controller 12 combinations are made, and belt pulley 13 and 14 is staggered and is an end of main shaft 10; The axis part of boring bar 6 studs with cemented carbide 15, is associated with on the boring bar 6 by its front axis part and is milled with two not deflectors 16 of the Baltimore groove of UNICOM, and reaching with the axial line gradient is the micro-adjusting mechanism of oblique forks 17 compositions of 1.5 degree; The both sides of lathe bed 2 are equipped with travel switch 19 and 20 respectively; Two flow speed control valves 21 and 22 are equipped with in fine filter below in the hydraulic system of fuel tank 1, and a solenoid directional control valve 23 is set before or after flow speed control valve 21 and 22, and main oil pump 24 is used variable vane pump.The operation and the using method of this fine boring machine have technology with method.

The utility model is described in further detail below in conjunction with accompanying drawing:
This fine boring machine is made up of fuel tank 1, lathe bed 2, electrical system 3, outer cover 4, pipe-line system 5, boring bar 6, anchor clamps 8 and static pressure fuel tank 9 by known coupling method.Wherein, for making compact conformation, increase rigidity, improve the roughness on boring surface, the support part of the main shaft 10 of boring head 7 is manufactured-, simultaneously known belt pulley 13 and 14 is arranged in main shaft 10 first alternately by directly being embedded in the known hydrodynamic and hydrostatic pressure on the main shaft 10 shell spares or the one-piece parts of hydrostatic bearing 11 and flow controller 12 combinations.For improving the rigidity of boring bar 6, realize fine setting, axis part at boring bar 6 is inlaid with cemented carbide 15, on boring bar 6, be associated with by its front axis part and be milled with two not deflectors 16 of the Baltimore groove of UNICOM, reaching with the axial line gradient is the micro-adjusting mechanism of oblique forks 17 compositions of 1.5 degree, and the outside and the main shaft of the deflector 16 in the micro-adjusting mechanism connect firmly, and belong to standing part, inner and boring bar 6 links, and belongs to adjustable part.During fine setting, move tiltedly fork 17, deflector 16 will be around its axis tilt certain angle, and boring bar 6 is the corresponding deflection certain angle also, because tiltedly fork 17 angles are less, can realize point of a knife micron order fine setting radially.For the Integrated Chip that makes workbench is convenient to shower nozzle by workbench top towards Xian, casting one inclined plane 18 below the central guide track of lathe bed 2.For making travel switch break away from the cooling fluid workspace, improve safety in operation, known travel switch 19 and 20 is loaded on the both sides of lathe bed 2 respectively.For the feed speed that makes this boring machine is regulated flexibly, below the fine filter of the hydraulic system of fuel tank 1, two known flow speed control valves 21 and 22 are housed, and a known solenoid directional control valve 23 is set before or after flow speed control valve 21 and 22.For reducing the temperature rise of horizontal fineboring machine fuel tank, the main oil shaft pump in the system adopts known variable vane pump 24.The same prior art of the operation of this fine boring machine and using method.
The utility model compared with prior art has main shaft and boring bar good rigidly, can realize radially little of point of a knife The meter level fine setting, cooling and easy to clean after the cutting, the hydraulic system feeding is steady, and flexible adjustment can improve it and add The advantages such as worker's precision and surface roughness.
