Abstract

The utility model discloses a carriage structure for a lathe, which comprises a small carriage of a lathe, wherein the small carriage of a lathe is formed by the match of a small dovetail body and a small dovetail groove body. One side wall of a reentrant of the small dovetail groove body is a slope, and the other side wall is a groove, wherein a chock is matched in the groove. A slope of a chock is symmetric to the slope of one side wall of the reentrant of the small dovetail groove body to jointly form a groove cavity of the small dovetail groove body, and a convex body of a chock is in clearance fit with the small dovetail groove body in a vertical direction. An adjusting screw used for adjusting clearance is arranged on the outer side of the groove at the other side wall of the small dovetail groove body, and a press screw used for pressing the chock is arranged on the upper surface of the groove of the small dovetail groove body. The chock and the small dovetail groove body form a dovetail groove, and because the height of the chock is a little smaller than that of the small dovetail groove body, both upper surfaces of the small dovetail groove body only need to be machined on the contact surface of a body of a dovetail groove and the small dovetail body. Under the condition that the small carriage is not pulled apart and the pressing screw is loosened, the screw can be directly adjusted to change the clearance of dovetail slopes.
