Abstract

The utility model discloses a precise lathe tail seat which comprises a base seat, a sleeve, a locking handle, a thread bar and a hand wheel. The front part of the sleeve is provided with a finely-reinforced kit which is made of wear-resistant materials. The fine-reinforced kit is flexibly matched with the sleeve. The conjugation space is kept within 0.020 millimeters. The fine-reinforced kit prolongs a bearing surface of the sleeve so as to avoid the reduction in the processing accuracy due to sleeve libration. When the fine-reinforced kit is worn and torn, and affects the processing accuracy, the fine-reinforced kit should be replaces with a new one. The replacement process is convenient and fast. The utility model can enhance the processing accuracy of the workpiece, and prolong the service life of the tail seat. The utility model is of good application performance and is of broad market prospects.

Description

The accurate tailstock of lathe
Technical field
The utility model relates to a kind of tail stock, especially the accurate tailstock of lathe.
Background technology
Traditional lathe tailstock structure generally includes base, sleeve, leading screw, handwheel and set lever, drive the leading screw rotation by shaking handwheel during use, and then the promotion sleeve carries out axially-movable in base, when the set thimble of sleeve ends holding out against on the workpiece put in place after, the set lever locking sleeve that manipulation is located on the base can carry out workpiece processing, because the vibration that produces in the axially-movable that sleeve is frequent and the course of work, make the faying face sharp wear of sleeve and base, especially in base aperture oral area position, after set lever locking, the axle center that originally is in same horizontal sleeve and main shaft produces skew, make the workpiece after the installation be in heeling condition, produce error when causing cutting and influence precision, the cylindrical ovalize that goes out with the lathe tool car for example, reduce in order to overcome the machining accuracy that causes thus, big multi-vendor way is to increase the base aperture, again make the sleeve that matches with this aperture, though this method is also calculated a kind of means that solve wear problem, but solve trouble, again make the time-consuming especially expense material of sleeve, the way that neither thoroughly deal with problems.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of easy assurance precision is provided, improves tailstock service life, changes the accurate tailstock of convenient and anti abrasive lathe.
Technical problem of the present utility model is achieved through the following technical solutions:
The accurate tailstock of a kind of lathe comprises the handle of base, sleeve, locking sleeve, leading screw and connect the handwheel of leading screw, and it is characterized in that described base leading section is provided with the essence of sleeve active mounting overlaps admittedly.
Compared with prior art, the utility model has additional the essence with the sleeve active mounting that high-abrasive material makes at the base leading section of original tail stock and overlaps admittedly, the bearing-surface of sleeve is prolonged, thereby avoid reducing problem because of the machining accuracy that the sleeve vibration causes, even overlap wearing and tearing admittedly and when influencing machining accuracy in essence, the essence that only needs directly more to renew is overlapped admittedly and is got final product, and changes very conveniently, has better Practical Performance and market prospects widely.
Description of drawings
Fig. 1 is the utility model sectional structure schematic diagram.
Fig. 2 overlaps schematic diagram admittedly for essence.
The specific embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1~shown in Figure 2, the accurate tailstock of lathe, comprise the base 1 that is slidingly mounted on the lathe guide rail, be provided with sleeve 2 in the base, base top is provided with the set lever 4 of locking bushing, be provided with the leading screw 5 that is threaded with it in the sleeve, be provided with the swivel nut 7 of locating leading screw at sleeve ends, it is fixing with outside handwheel 6 that leading screw passes base.The base leading section also is provided with the essence of sleeve 2 active mountings and overlaps 3 admittedly, and this essence is overlapped employing admittedly and made through high-abrasive materials such as heat treated spheroidal graphite cast-iron, bearing steels, has good wear resistance.
When the needs top tight workpiece adds man-hour, shake handwheel 6 and drive leading screw 5 rotations, and then the sleeve 2 that promotes to be threaded passes the set essence of base 1 leading section and overlaps 3 admittedly and prolong axially outwards motion, after the set thimble (not shown) top tight workpiece of sleeve ends puts in place, handle set lever 4 locking bushings 2 positions, can carry out the processing of workpiece.The essence that this tailstock adopts is overlapped 3 admittedly and is remained in 0.020 millimeter with the fit clearance of sleeve 2, and the gap is more little, and then machining accuracy is high more.
The utility model adds man-hour at top tight workpiece, and the position that need bear vibratory impulse power moves to smart 3 the front end aperture of overlapping admittedly from the front end aperture of base, and the wearing and tearing back only needs the smart solid cover of transposing to get final product, convenient and swift, have good practicability, and can improve the workpiece machining accuracy, prolong tailstock service life.
