Abstract
The utility model provides a boring lathe used for machining curve shaft holes of an engine cylinder body, which comprises a boring lathe working platform, a base, a location plate, a spindle, a boring rod and a boring knife fixed on the circumferential face of the boring rod, wherein the base is fixed on the upper surface of the boring lathe working platform, the location plate is fixed on the upper surface of the base, and the head end of the boring rod is installed on the spindle. The boring lathe is characterized in that the tail end of the boring rod is connected into a support mechanism fixed on the base, so that the boring rod cannot swing when lengthened, and the lengthened boring rod can finish machining the curve shaft holes once without rotating the boring lathe working platform. The boring lathe not only improves machining accuracy but also improves machining efficiency.
Description
Technical field
The utility model relates to a kind of boring machine of processing engine cylinder-body, relates in particular to a kind of boring machine of processing the engine cylinder-body crankshaft hole.
Background technology
The crankshaft hole of engine cylinder-body is one of cylinder body processing key operation, removes hole tolerance, garden post degree, and outside the roughness, five crankshaft hole linearitys also are crucial parameters.If this parameter do not reach requirement, gently then influence the bent axle smooth rotation, bearing shell produces uneven wear, and is heavy then bent axle can't normal rotation.And five endoporus processing lengths are 372.5 millimeters, and linearity is 0.005 millimeter, belong to interrupted cut, and difficulty of processing is very big.Existing boring machine comprises main shaft, boring bar and is fixed on the boring cutter of boring bar periphery, and an end of boring bar is installed on the main shaft, and the other end of boring bar is unsettled, and the length of boring bar can not be long, otherwise boring bar can produce and rock, and reduces machining accuracy.Therefore process the engine cylinder-body of five dead eyes for needs; Add wherein rotary table turnback reprocessing 2 dead eyes in addition behind 3 holes of man-hour elder generation boring; Its linearity of this processing method depends on machining center rotary table precision fully; Overproof scrapping often appears in product, and owing to need rotary table, reduced operating efficiency.
The utility model content
The technical problem that the utility model solves is: a kind of boring machine of processing the engine cylinder-body crankshaft hole is provided, can disposablely machines crankshaft hole, and improve machining accuracy and working (machining) efficiency.
The technical scheme of the utility model is: a kind of boring machine of processing the engine cylinder-body crankshaft hole comprises boring table, base, location-plate, main shaft, boring bar and is fixed on the boring cutter of boring bar periphery, wherein; Said base is fixed on the boring table upper surface; Said location-plate is fixed on base upper surface, and the head end of said boring bar is installed on the main shaft, it is characterized in that; The tail end of said boring bar is connected in the supporting mechanism, and this supporting mechanism is fixed on the said base.
Said supporting mechanism comprises that cross section is the sleeve of " ┬ " shape, clutch shaft bearing, second bearing and bearing cap; Said bearing cap is fixed on the said base; Said clutch shaft bearing and said second bearing holder (housing, cover) are located on the said sleeve path section; The end of said sleeve path section is provided with locking nut, and between the bigger diameter end and locking nut of sleeve, the tail end of said boring bar is inserted in the sleeve by axial limiting for clutch shaft bearing, second bearing.
Said sleeve and boring bar are positioned on the same axis.
Be provided with spacer ring between said clutch shaft bearing and said second bearing, this spacer ring is set on the path section of said sleeve.
The beneficial effect of the utility model is: the tail end of the boring bar of the utility model is connected in the supporting mechanism; Supporting mechanism is fixed on the base; Make can not produce behind the length lengthening of boring bar and rock that the boring bar behind the lengthening can disposablely machine crankshaft hole, need not rotate boring table; Not only improve machining accuracy, and improved working (machining) efficiency.
