Abstract

The invention relates to a clamping centering device for shafts. The clamping centering device for shafts comprises a base, a rotating ring, lock blocks, connecting bars, a pneumatic telescopic bar, and a rotating rocker. An outer fixing ring and an inner fixing ring are arranged on the base; the center of the inner fixing ring is provided with a shaft round through hole; a circular groove is arranged between the outer fixing ring and the inner fixing ring. The rotating ring is mounted in the circular groove through press plates evenly distributed. The lock blocks around a shaft are evenly distributed on the outer end face of the inner fixing ring. One end of the rotating rocker is fixed on the outer end face of the rotating ring through a bolt; the other end of the rotating rocker is connected with the pneumatic telescopic bar; the pneumatic telescopic bar drives the rotating rocker and the rotating ring to rotate by extending or shortening, so that the lock blocks are driven to move in or out through the connecting bars so as to lock or loosen the shaft, and the shaft is centered and clamped. The clamping centering device for shafts is simple in structure, convenient to operate and adjustable in clamping size, and can operate reliably.

Description

technical field [0001] The invention relates to a pinch clamp centering device for shafts, in particular to a centering and fixing device for shafts. Background technique [0002] It is suitable for the fixed pinching clamp of shaft parts, and is an important clamping and clamping device in machine tool and shaft processing. In the production, processing and testing process of mechanical parts, it is usually necessary to support and fix the parts. Therefore, the clamp centering device is used as a fixing device to obtain a higher utilization rate. Although the various pinching devices currently used can pinch parts, they cannot be centered, and center line deviation often occurs. Therefore, there is a need for a centering and pinching device, which can not only realize the pinching function, but also realize the centering function at the same time. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficienci...
