Problems solved by technology

There are the following problems: 1. Manually adjust the centering of the support points, which is inefficient; 2. There is sliding friction between the workpiece and the top support block of the chuck jaw, which is easy to wear and has a short life; 3. The outer circle of the workpiece blank cannot be used directly and must be processed The positioning port is used for the positioning of the center frame, and the efficiency is low; 4. The installation is poor. The upper and lower parts of the center frame are linked by simple bolts.

Abstract

The invention belongs to the technical field of machine tool machining auxiliary equipment and particularly provides a self-centering rotary completely-closed center frame. The center frame comprises a base, a frame body and a circularly annular rotary body. The base is fixed to a machine tool. The frame body is connected with the base and is connected with the rotary body rotationally. 3 clamping oil cylinders are fixed to the annular circumference of the rotary body. Through telescopic movement of piston rods of the clamping oil cylinders, a to-be-machined workpiece is clamped to be machined by the machine tool. According to the self-centering rotary completely-closed center frame, through the clamping oil cylinders, a self-centering function is achieved, the procedure that a center frame locating belt is machined on the workpiece is avoided, and labor time is reduced. The rotary body and the workpiece rotate together relative to the frame body, thus friction of the workpiece on a clamping jaw is avoided, and the equipment service life is prolonged. In addition, the frame body and the base can rotate relatively by a certain angle, and thus the workpiece can be put into the position conveniently.

Description

technical field [0001] The invention belongs to the technical field of machine tool processing auxiliary equipment, and in particular provides a self-centering rotating fully enclosed center frame. Background technique [0002] The center frame is an auxiliary device for radially supporting the rotating workpiece during processing. During processing, there is no relative axial movement with the workpiece. The center frame mostly adopts a three-jaw centering structure. The existing center frame mostly uses a manual structure to clamp the three chuck claws to the rotating workpiece. The rotating workpiece rotates, but the center frame does not rotate. There are the following problems: 1. Manually adjust the centering of the support points, which is inefficient; 2. There is sliding friction between the workpiece and the top support block of the chuck jaw, which is easy to wear and has a short life; 3. The outer circle of the workpiece blank cannot be used directly and must be ...
