Abstract
The utility model belongs to machine tool series, and particularly relates to a tailstock with chucks, which is used on a lathe, and consists of chucks (4) and a tailstock body (14). The tailstock with chucks is characterized in that the construction center comprises chuck roots (9) and a bearing core sleeve (11), wherein the chuck root (9) are internally provided with a single-row radial ball bearing (8) and a single-direction thrust ball bearing (10), and the bearing core sleeve (11) is internally provided with a tapered hole; the bearing core sleeve (11) is fixedly matched a cone-shaped body (13) arranged at the front end of the tailstock body (14); the chuck roots (9) are fixed at the rear end of the chucks (4) by bolts (7); the bearings built in the chuck roots (9) are assembled on the shaft diameter of the bearing core sleeve (11) and fixed by check rings (12); and a circle of balls (6) are arranged between the inner end surfaces of the chuck roots (9) and the front end surface of the bearing core sleeve (11). In the utility model, the two chucks clamp a workpiece together from two ends so as to process the workpiece, and the efficiency for processing substandard semifinished product pieces is high.
Description
Technical field:
The utility model belongs to the machine tool class, is specifically related to the band chuck tailstock of using on a kind of lathe.
Background technology:
At present in the engine lathe production and processing; especially on large-scale engine lathe; in substandard forging, the processing of cast steel blank; centering, centering; it all is sub-fraction with one of head of a bed chuck mounting board workpiece; the weight of workpiece 90% and area all are unsettled on lathe bed; it is very difficult carrying out centering and centering like this; the workpiece phenomenon that falls down appears through regular meeting; cause the damage of equipment and the injury of the person; the operator will bear out a lot of muscle power and time, also has danger, inefficiency.
Summary of the invention:
The purpose of this utility model, provide the chuck tailstock of using on a kind of lathe, at the chuck that is provided with on the tailstock on the revolvable chuck cooperation head of a bed, two chucks from two together the mounting board workpiece carry out centering and processing, the tailstock mandrel drives drill point and centre drill, can finish the work of centering in tailstock chuck endoporus freely, to centering, the centering of workpiece, processing all is very convenient, fast, safe, efficient like this.
Technical scheme is: a kind ofly be used in band chuck tailstock on the lathe, be made up of chuck, tailstock body, it is characterized in that: be provided with in organization center also comprises single-row radial ball bearing and single direction thrust ball bearing the chuck root and in be provided with the bearing core retainer plate of bellmouth.
The bullet immovable fitting that described bearing core retainer plate and tailstock body front end are provided with, described chuck root is fixed by bolts to the rear end of chuck, and the built-in bearing of chuck root is assemblied on the diameter of axle of bearing core retainer plate, and locatees with back-up ring.
Be equipped with a circle ball between the front end end face of the inner face of described chuck root and described bearing core retainer plate.
The utility model advantage is: two chucks from two together workpiece of mounting board process, to machining large not specification forge, the blank of cast steel, mounting board is safer, centering is faster, centering is simpler and easy, the processing efficient of getting up is higher.
Description of drawings:
Fig. 1 is a band chuck tailstock schematic diagram:
Mark among the figure: 1, be chuck jaw, 2, be centre drill, 3, be drill point, 4, be chuck, 5, be tailstock mandrel, 6, be ball, 7, chuck set bolt, 8, be single-row radial ball bearing.9, be chuck root, the 10th, single direction thrust ball bearing, 11, be bearing core retainer plate, 12, be back-up ring, 13, be bullet, 14, be tailstock body, 15, be tailstock set bolt, 16, be crank.
The specific embodiment:
Be described further below in conjunction with embodiment:
Referring to Fig. 1, the band chuck tailstock of using on a kind of lathe is made up of chuck 4, single-row radial ball bearing 8, chuck root 9, single direction thrust ball bearing 10, bearing core retainer plate 11, tailstock body 14.Wherein chuck root 9 endoporus are provided with single-row radial ball bearing 8 and single direction thrust ball bearing 10 and bearing core retainer plate 11, be provided with bellmouth in the bearing core retainer plate 11, tailstock body 14 1 ends are outside equipped with bullet 13, and with bearing core retainer plate 11 bellmouth immovable fitting, ball 6 edges are clipped between chuck root 9 and the bearing core retainer plate 11, play and separate chuck root 9 and can not contact with bearing core retainer plate 11, play thrust and turning effort again, back-up ring 12 is to be threaded with chuck root 9, block single direction thrust ball bearing 10, crank 16 rotations promote tailstock mandrel 5 and drive drill point 3 and centre drill 2, the flexible centering of free safety in tailstock chuck 4 endoporus, tailstock chuck 4 cooperates head of a bed chuck to be rotated work from workpiece of two mounting board together, this is to the substandard forging of machining large, the blank of cast steel, mounting board is safer, and centering is faster, centering is simpler and easy, and working (machining) efficiency is higher.
