Abstract

The invention provides a power head, which belongs to the technical field of machinery. It solves the problem of poor stability of the existing power head when it starts and stops. The power head of the improved structure includes a main body and a main shaft passing through the main body, the main body is provided with a connecting flange for connecting to a machine tool, the power head also includes a rotation driving source for driving the main shaft to rotate, and a main shaft for driving the main shaft to rotate. A synchronous pulley transmission assembly connecting a rotary drive source and a main shaft, the synchronous pulley transmission assembly includes a driven wheel sleeved outside the main shaft, characterized in that the rotary drive source and the main shaft are axially fixed, and the driven wheel A ring-shaped expansion sleeve is arranged between the expansion sleeve and the main shaft. The outer peripheral wall of the expansion sleeve abuts against the driven wheel and the inner peripheral wall of the expansion sleeve abuts against the main shaft. The driven wheel is expanded and positioned on the main shaft through the expansion sleeve. . The power head of the improved structure has good stability in the start-stop state.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a machined part, in particular to a power head. Background technique [0002] The power head is a power component that can realize main movement and feed movement, and has automatic workpiece circulation. It is a relatively simple variable speed transmission mechanism with various forms. The basic principle is that the motor drives a gear transmission mechanism, which can realize functions such as boring, milling, and drilling. Some have guide rails and can move linearly in a small range. The power head mainly realizes different processing through the rotation and feed of the main shaft. The existing middle power head is divided into horizontal type and vertical type according to the way it cooperates with the installation surface of the machine tool. The body of the vertical power head is provided with a connecting flange, which is connected against the machine tool through the...
