Abstract
The utility model relates to a turning-lathe tailstock center comprising a center shaft (1), a center sleeve (2), a bearing and a sleeve gland (3). The bearing comprises a first bearing (4) and a second bearing (5) which are arranged in the inner wall of the sleeve. The center sleeve (2) is fixedly connected with one end of the center shaft (1) through the bearing, and the other end of the center shaft (1) extends out of the sleeve gland (3). According to the turning-lathe tailstock center, machining precision is high, machining friction force is small, the center sleeve plays a role in protecting, abrasion can not caused by the center shaft which is used for a long time, application range of an original turning-lathe is widened, and large parts can be machined by the turning-lathe. Therefore, a new turning-lathe is not needed buying and cost is saved.
Description
Technical field
It is top that the utility model relates to a kind of tail stock.
Background technology
Lathe is the lathe that mainly with lathe tool the workpiece of rotation is carried out turning processing.Tail stock is mainly by tailstock body, form with the sleeve of internal taper hole, screw mandrel etc., and the effect of tail stock mainly is to hold work with top, and bears cutting force.
During the lathe grinding workpiece, be to utilize the chuck of headstock and the tailstock centre that is installed in lathe tail to fix workpiece.Tail stock is top to be the benchmark bearing carrier of machine cut processing, has that certain load-bearing rigidity and intensity are top can stretch flexibly, can accurately locate again, and tailstock centre making precision itself has determined the processing and manufacturing precision of product.The CW61100E lathe is to use at present very widely one of lathe model, it is larger that the tailstock tailstock centre of this lathe adds man-hour frictional force, thereby long-time use can cause wearing and tearing so that machining accuracy is not high, and can't the machining large parts large-scale industrial and mineral parts for example, do not satisfied real need of production, and it is larger to purchase the spent cost of new lathe.
The utility model content
The purpose of this utility model is exactly that to solve the tailstock machining accuracy of lathe not high, adds man-hour frictional force larger, problem that can't the machining large parts.
The technical solution adopted in the utility model is: a kind of tail stock is top, and it comprises tail spindle, tailstock sleeve, bearing and sleeve gland, and described bearing comprises clutch shaft bearing and the second bearing that is positioned at sleeve lining; One end of described tail spindle is fixedly connected with tailstock sleeve by bearing, and the other end stretches out the sleeve gland.
As further improvement of the utility model, described clutch shaft bearing is the single-row centripetal cylindrical roller bearing, and the second bearing is single-row tapered roller bearing.
As further improvement of the utility model, described tailstock sleeve outer wall has 4 screw holes, and screw hole is positioned at the tailstock sleeve outer wall and evenly distributes, and the bottom of screw hole is near the second bearing.
As further improvement of the utility model, described screw hole is M27 * 2mm screw hole.
As further improvement of the utility model, the tapering of described tail spindle is 1:20.
The beneficial effect that the utility model adopts is: after having adopted this technical scheme; machining accuracy is high, it is less to add man-hour frictional force; tailstock sleeve has played protective effect; tail spindle can not cause wearing and tearing for a long time yet; enlarged simultaneously the scope of application of former lathe; so that lathe can the machining large parts, needn't purchase new lathe like this, saved cost.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Shown in the figure: 1, tail spindle, 2, tailstock sleeve, 3, the sleeve gland, 4, clutch shaft bearing, the 5, second bearing, 6, screw hole.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, preference of the present utility model is that a kind of tail stock is top, and it comprises tail spindle 1, tailstock sleeve 2, bearing and sleeve gland 3, and the tapering of described tail spindle 1 is 1:20; Described bearing comprises clutch shaft bearing 4 and the second bearing 5 that is positioned at sleeve lining, and described clutch shaft bearing 4 is the single-row centripetal cylindrical roller bearing, and the second bearing 5 is single-row tapered roller bearing; One end of described tail spindle 1 is fixedly connected with tailstock sleeve 2 by bearing, and the other end stretches out sleeve gland 3; Described tailstock sleeve 2 outer walls have 4 M27 * 2mm screw hole 6, and described screw hole 6 is positioned at tailstock sleeve 2 outer wall both sides, and the bottom of screw hole 7 is near the second bearing 5.
After having adopted this technical scheme, at tail spindle tailstock sleeve is set, has played protective effect, tail spindle can not cause wearing and tearing for a long time yet; Single-row centripetal cylindrical roller bearing and single-row tapered roller bearing are used in combination, and have reduced friction; The Morse's taper of tail spindle and the Morse's taper of tailstock tool are consistent, and bearing accuracy is got the D class precision, has guaranteed machining accuracy; The M27 that the tailstock sleeve outer wall arranges * 2mm screw hole is used for installing the adjustment screw rod, make so the top topmast that can not only be used for of tail stock support and can be used in interior topmast support cutting, enlarge like this scope of application of former lathe and needn't purchase new lathe, saved cost.
