Problems solved by technology

The valve seat can be processed by a lathe. Some valve seats have a sloped inner hole, and the axis of the inner hole and the axis of the valve seat have a certain offset. Processing, when processing a workpiece that needs to be turned at both ends, it needs to be clamped twice, which affects the work efficiency and easily causes the deviation of the coaxiality of the two ends of the workpiece, which cannot meet the requirements of use. The existing lathe tool holder is adjusting The height is achieved by adding or reducing gaskets at the bottom of the tool holder. This method requires a large number of gaskets, which is very troublesome to adjust. At the same time, the structure is unstable. When the parts are pr

Abstract

The invention relates to a lathe for machining an inner slope of a valve seat. The lathe comprises a frame, wherein a spindle box is arranged on the frame, a rotating shaft is arranged at the output end of the spindle box, a clamping device used for clamping a workpiece is arranged on the rotating shaft, and a tilting device used for enabling the clamping device to tilt relative to the rotating shaft and an adjusting device used for enabling the clamping device to shift in the radial direction of the rotating shaft are arranged between the rotating shaft and the clamping device. Compared withthe prior art, by means of the structure, an existing lathe can obtain the valve seat of which an inner hole is inclined and has a certain offset.

Description

technical field [0001] The invention relates to the technical field of valve seat processing, in particular to a lathe used for processing an inner inclined surface of a valve seat and a use method thereof. Background technique [0002] The valve seat is a detachable surface part in the valve, which is used to support the fully closed position of the valve core and constitute a sealing pair. The valve seat can be processed by a lathe. Some valve seats have a sloped inner hole, and the axis of the inner hole and the axis of the valve seat have a certain offset. Processing, when processing a workpiece that needs to be turned at both ends, it needs to be clamped twice, which affects the work efficiency and easily causes the deviation of the coaxiality of the two ends of the workpiece, which cannot meet the requirements of use. The existing lathe tool holder is adjusting The height is achieved by adding or reducing gaskets at the bottom of the tool holder. This method requires ...
