Abstract
The invention discloses a lathe center frame. A radial ball bearing is arranged in a slot at the middle of the front end of a clamping jaw which is used generally, and the radial ball bearing rotates around a workpiece under the action of a cutting force, thus abrasion of the clamping jaw is reduced. The invention has the advantages of prolonging the service life of a clamp and reducing the cost consumption through application.
Description
Affiliated technical field
The present invention relates to a kind of lathe centre frame.
Background technology
At present, the centre frame that domestic machined into is used is that machine tool accessory factory produces, and in use jaw and workpiece mating part will add machine oil, and jaw is in use easy to wear.
Summary of the invention
For deficiency easy to wear in the lathe centre frame use that overcomes present use, the present invention provides a kind of lathe centre frame, and it is simple in structure, makes easily, and is easy to operate.
The technical method that the present invention adopts is: fluting in the middle of the normally used jaw front end is installed radial ball bearing, and radial ball bearing around the workpiece centre rotation, reduces the jaw wearing and tearing under the effect of cutting force.
The invention has the beneficial effects as follows,, improve anchor clamps service life, reduce cost consumption through application of the present invention.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a structural representation.
