Adjustable centering clamp for numerical control machine

Abstract

The invention relates to an adjustable centering clamp for a numerical control machine. The adjustable centering clamp comprises a connecting plate, a centering base, a cylinder, bearing bases and bearings, wherein the centering base is mounted at one end of the connecting plate in an orthohexagonal form; three bearing bases are uniformly placed in the middle of the centering base around the center; the bearings are mounted at the front ends of the bearing bases and are faced to the center of the centering base; a cylinder door cover is mounted on a side wall at the upper end of the centering base; the cylinder is mounted at the upper end of the cylinder door cover; an ejecting rod of the cylinder downward passes through the cylinder door cover and is connected with one of the bearing bases in the centering base; fine tuning door covers are fixedly mounted on symmetrical side walls on the two sides at the lower end of the centering base; a fine tuning shaft which is vertical to the fine tuning door covers is mounted at the centers of the fine tuning door covers; one end of the fine tuning shaft is respectively connected with the other two bearing bases; and the other end of the fine tuning shaft is connected with a fine tuning handle. The adjustable centering clamp for the numerical control machine is simple in structure and convenient in operation; the adjustable centering clamp is used for fixing tail parts of long shafts during a processing process, so as to ensure the stable rotating of the long shafts; the processing quality of products is increased; and the rejection rate is reduced.

Description

technical field [0001] The invention relates to the field of auxiliary machinery for numerical control machine tools, in particular to an adjustable centering fixture for numerical control machine tools. Background technique [0002] CNC machine tools are mainly used to process shaft parts, and in many cases, relatively long shaft parts need to be processed. When processing long shaft parts, a section of the shaft is fixed on the machine tool spindle. Due to the long length of the shaft, the tail of the long shaft will sag, resulting in a height difference between the tail and the head of the long shaft. When the main shaft is rotating, the long-axis parts will be unstable, resulting in different cutting depths on the shaft, and waste products are prone to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adjustable centering fixture for CNC machine tools, which is simple in structure and easy to operate...
