Abstract
The utility model provides a taper-shank moving cartridge for processing long shaft article, which is characterized in that a connecting shaft is arranged in the frontend of the taper shank matched with the taper hole of the lathe tailstock; two single-row radial ball bearings and a single-row thrust ball bearing are installed on the connecting shaft; in addition, a position shaft sleeve and a locking circlip are arranged on the connecting shaft; a connecting sleeve is coated on the housing washers of the two single-row radial ball bearings and the front end of the single-row thrust ball bearing; a four-jaw chuck is arranged at the front end of the connecting sleeve, which eliminates the loosing phenomenon of the long shaft article being mounted on the lathe tailstock. The working piece can be chucked firmly, the center of the working piece is adjustable, and the machining allowance is decreased; in addition, the utility model has the advantages of simple structure and easy production.
Description
Technical field
The utility model relates to a kind of lathe of machine cut processing, and especially a kind of major axis class part is processed with taper shank chuck alive.
Background technology
The processing of axial workpiece is at present mainly finished by lathe, and its process is that the end with axial workpiece steps up on the chuck of lathe spindle, and the other end is fixed on tail stock top.But many longaxones parts are arranged, and as hydraulic machine column, pull bar etc., its draw ratio is much larger than 10, because its weight is bigger, tighten by spindle chuck at the machined into Shi Yiduan that is installed, the other end can produce a sagging naturally power, top pressure to tail stock is very big, easily produces the phenomenon that gets loose.Therefore it is very unreliable to be installed like this.
Summary of the invention
The utility model provides a kind of simple in structure, reliable major axis class part processing that is installed with the taper shank chuck of living for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of major axis class part is processed with taper shank chuck alive, by chuck, the taper shank that is installed in the chuck rear end is formed, described taper shank front end is shaped on connecting axle, two single-row radial ball bearings and a location axle sleeve are installed on the connecting axle front and back end, at the connecting axle front end a single-row thrust ball bearing and locking elastic back-up ring are installed also, with a single-row thrust ball bearing front end adapter sleeve that is connected with chuck is installed in two single-row radial ball bearing outer rings, be shaped on the annular boss that is complementary with chuck rear end seam on the front end face of adapter sleeve, the screw that connects chuck also is installed on the front end face of adapter sleeve.
The utility model can also adopt following technical measures:
Described chuck is a chuck.
Advantage and the good effect that the utlity model has are: because the rotating chuck that has bearing is installed on tail stock, when being installed the major axis part, can tighten the tail end of part securely, avoided getting loose easily phenomenon, there is chuck can also adjust workpiece centre again, this reduces allowance when helping turning processing blank part, be saving of labor's material-saving again, the utility model also has advantage simple in structure, that be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the top taper hole of the tapering of taper shank 10 and tail stock is complementary, and the front end of taper shank also is shaped on coaxial with it connecting axle 11.Two single-row radial ball bearings 5 and location axle sleeve 6 are installed on the connecting axle front and back end, a single-row thrust ball bearing 4 and locking elastic back-up ring 3 also are installed at the front end of connecting axle.At outer ring and adapter sleeve 7 of a single-row thrust ball bearing front end suit of two single-row radial ball bearings, the front end of adapter sleeve is equipped with chuck 1 and the trip bolt 2 thereof that the rear end has positioning spigot 13.The front end of adapter sleeve also is shaped on the annular boss 12 that is complementary with the chuck positioning spigot, and the clamp nut 9 that Packed felt pad 8 and screw thread are installed also is installed in the rear end of adapter sleeve.
Claims (2)
1. a major axis class part is processed with taper shank chuck alive, by chuck, the taper shank that is installed in the chuck rear end is formed, it is characterized in that: described taper shank front end is shaped on connecting axle, two single-row radial ball bearings and a location axle sleeve are installed on the connecting axle front and back end, at the connecting axle front end a single-row thrust ball bearing and locking elastic back-up ring are installed also, with a single-row thrust ball bearing front end adapter sleeve that is connected with chuck is installed in two single-row radial ball bearing outer rings, be shaped on the annular boss that is complementary with chuck rear end seam on the front end face of adapter sleeve, the screw that connects chuck also is installed on the front end face of adapter sleeve.
