Abstract
The invention relates to a numerical control vertical lathe spindle assembly. In the invention, the upper end of a spindle is connected with a disk body, the lower end of the spindle is connected with a power wheel, a cylindrical spindle sleeve is sheathed on the spindle, the middle section of the outer wall of the spindle sleeve is provided with an annular subpanel, the periphery of the annular subpanel is evenly distributed with bolt holes, the lower part of the disk body is provided with a circular groove which is convex upwards, the upper part of the outer wall of the spindle sleeve is provided with a ladder platform, a crossed cone roller bearing is arranged between the circular groove in the lower part of the disk body and a ladder platform of the outer wall of the spindle sleeve, a deep groove ball bearing is arranged between the upper section of the inner periphery of the power wheel and the spindle sleeve, a deep groove ball bearing is arranged between the lower section of the inner periphery of the power wheel and the lower end of the spindle, and a seal groove is arranged on the outer periphery of the spindle sleeve. In the invention, the spindle is arranged in the spindle sleeve and matches with the spindle sleeve; the size of the spindle sleeve is smaller than the size of the lathe body, so the size with higher matching precision compared with the spindle can be easily processed to enable the precision of the numerical control vertical lathe to be more higher; and the crossed cone roller bearing is arranged between the circular groove in the lower part of the disk body and the ladder platform of the outer wall of the spindle sleeve, the disk body has considerable loading capacity, and the rotation precision of the spindle is guaranteed to be higher.
Description
Technical field
The present invention relates to the axle sleeve and the bearing of a kind of numerical control vertical lathe spindle, particularly a kind of numerical control vertical lathe spindle.
Background technology
NC vertical lathe has main shaft, the main shaft upper end is connected with the disc disk body of axis on same straight line of axis and main shaft, the lower end of main shaft is connected with power input wheel, and the vertical spindle of NC vertical lathe will have higher rotating accuracy, and the disk body that is connected in the main shaft upper end will have bigger bearing capacity.In the prior art, main shaft is mounted in the axis hole on the NC vertical lathe lathe bed.In order to make main shaft that higher rotating accuracy and bigger bearing capacity be arranged, main shaft is installed in requirement on the NC vertical lathe lathe bed axis hole has higher precision, when main shaft is installed in axis hole, the outer wall of main shaft and and lathe bed on the inwall of axis hole between 2～3 cylinder roller bearings and 1～2 deep groove ball bearing are arranged.The size of NC vertical lathe lathe bed is bigger, is difficult to produce the higher axis hole of precision on larger-size NC vertical lathe lathe bed, if the axis hole precision is not high, can cause the rotating accuracy of numerical control vertical lathe spindle not high; Produce the higher axis hole of precision on larger-size NC vertical lathe lathe bed, processing charges is higher; Bearing consumption between the axis hole on main shaft and the lathe bed is more, and particularly the price of cylinder roller bearing is higher, makes the cost of NC vertical lathe higher.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of rotating accuracy height, bearing capacity is big.Handling ease, the numerical control vertical lathe spindle assembly that processing charges is lower, the bearing consumption is few.
The present invention is achieved using the following method.
Numerical control vertical lathe spindle assembly has main shaft, the main shaft upper end is connected with the disc disk body of axis on same straight line of axis and main shaft, the lower end of main shaft is connected with power input wheel, main shaft is with the tubular axle sleeve of axis on same straight line of axis and main shaft, stretch out from the upper end of axle sleeve the upper end of main shaft, stretch out from the lower end of axle sleeve the lower end of main shaft, there is the annular mounting disc of axis on same straight line of axis and axle sleeve in the stage casing of axle sleeve outer wall, in the mounting disc, the bolt hole that is evenly distributed in along mounting disc, the circular groove of the oriented fovea superior in below of disc disk body, there is the ladder platform top of axle sleeve outer wall, between the circular groove of disc disk body below and the ladder platform of axle sleeve outer wall the crossed-circle taper roller bearing is arranged, between the epimere of power input wheel inner periphery and the axle sleeve lower end outer wall circumference deep groove ball bearing is arranged, the hypomere of power input wheel inner periphery is connected with terminal pad, between the lower end of terminal pad and main shaft deep groove ball bearing is arranged, the annular seal groove is arranged, sealing ring is arranged in the seal groove in sleeve outer circle week.
The present invention is installed on the NC vertical lathe lathe bed of the axle sleeve hole that matches with axle sleeve, the circular mounting platform that matches with the annular mounting disc in axle sleeve outer wall stage casing is arranged, on the erecting bed, along the internal thread hole that is evenly distributed in of erecting bed in the axle sleeve hole of NC vertical lathe lathe bed.During use, the present invention is placed in the axle sleeve hole on the NC vertical lathe lathe bed, the present invention is fixed on the erecting bed with bolt.
Main shaft of the present invention is installed in the axle sleeve, main shaft matches with axle sleeve, the size of axle sleeve is less than the size of the body of lathe bed, process the size that higher quality of fit is arranged with main shaft easily, make the precision of NC vertical lathe higher, between the circular groove of disc disk body below and the ladder platform of axle sleeve outer wall the crossed-circle taper roller bearing is arranged, make disk body have bigger bearing capacity, and guarantee that main shaft has higher rotating accuracy.After sealing ring can make the present invention be installed in the axle sleeve hole of NC vertical lathe lathe bed, clearance seal was oil-proof.
Below in conjunction with accompanying drawing, the present invention is further described.
