Abstract
A lathe center frame rotation ejector head for precision machining of a fine and long shaft comprises a spherical rolling body, a pressing cover, a base, a connection screw and a locking screw. The spherical rolling body is limited in a semi-spherical pit in the base by the pressing cover and can rolling in the pit, and the pressing cover is connected with the base through the screw. When the lathe center frame rotation ejector head is used, the rotation ejector head is directly arranged on a sliding supporting column of a center frame and then is located by the locking screw on the base.
Description
Technical field
The utility model relates to a kind of mechanical processing technique equipment, particularly a kind of for the accurately machined lathe center frame rotary jacking head of slender axles.
Background technology
In machining, in the time that workpiece to be machined is slender axles, for ensureing machining accuracy, often improve workpiece gyro rigidity with centre frame, on tradition centre frame, there are three adjustable sliding support posts, when use, the top of support column is withstood on the periphery of workpiece, thereby reach the supporting role to workpiece.But, owing to there being friction between sliding support capital end and workpiece, therefore, outer surface to workpiece has damage, also there are wearing and tearing on support column top simultaneously, in the time that workpiece speed of gyration is very high, outer surface of workpiece may be burnt, and changes this situation and will become very necessary so design a kind of new centre frame or centre frame annex.
Summary of the invention
The purpose of this utility model is to provide one for the accurately machined lathe center frame rotary jacking head of slender axles, and this apparatus structure is simple, with low cost, can effectively improve the gyro rigidity that slender axles add man-hour, thereby improves machining accuracy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of for the accurately machined lathe center frame rotary jacking head of slender axles, comprise spherical rolling body, gland, base, attachment screw, lock-screw.Spherical rolling body is limited in the hemispherical dimples on base with gland, and can roll in pit, and gland is connected it with screw with base.When use, rotary jacking head is directly contained on the sliding support post of centre frame, then with the lock-screw locking on base.
Use the beneficial effects of the utility model are: this device adopts spherical rolling body to contact with excircle of workpiece cylinder, become dry friction for rolling friction, reduce the damage to outer surface of workpiece, improved the gyro rigidity of workpiece simultaneously, thereby improved the machining accuracy of workpiece.The present invention is simple in structure in addition, easy to use.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model top view.
In figure: 1. sliding support post, 2. lock-screw, 3. base, 4. spherical rolling body, 5. gland, 6. attachment screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
When use, this device is arranged on the slipping column 1 of centre frame, and locked with lock-screw 2, then one end of workpiece being clamped with the scroll chuck on lathe, the other end withstands with top, then centering workpiece, and need to adjust centre frame position according to processing, adjust behind centre frame position, then by adjusting centre frame slipping column 1, the spherical rolling body 4 and excircle of workpiece Surface Contact that make three rotary jacking heads, reach the object to workpiece support.
Claims (1)
1. be used for the accurately machined lathe center frame rotary jacking head of slender axles in one, it is characterized in that: comprise spherical rolling body (4), base (3), gland (5), spherical rolling body (4) can roll in base (3).
