Problems solved by technology

[0002] For processing some precision parts, such as the dynamic and static pressure axial end face cavity with high requirements for depth dimension and shape tolerance, the lathe generally does not have the precise adjustment of the depth of the knife, and the manual scraper can only be adjusted to the end based on experience and technology, and it is difficult to guarantee the shape tolerance Moreover, the depth of the cavity is not easy to grasp, which also affects the processing efficiency.

Abstract

The invention provides a fine-adjustable tool bar for a lathe, which comprises a fixed tool bar, a movable tool bar and a fine-adjustment device arranged on the fixed tool bar. A square columnar inner hole with an open front end is arranged at the front end of the fixed tool bar, the rear end of the movable tool bar extends into the inner hole and is compressed in the inner hole through a compression nut in threaded fit with the fixed tool bar, and the front end of the movable tool bar is provided with a tool setting inner hole and extends out of the compression nut. The fine-adjustable tool bar for the lathe has the advantages of applicability to micro-feeding of a boring bar or a scraper bar for the lathe, high adjustment accuracy, and capabilities of meeting the requirements of parts on machining depth and shape tolerance and improving machining efficiency.

Description

technical field [0001] The invention relates to a processing tool for a lathe, in particular to a fine-tuning cutter bar for a lathe. Background technique [0002] For processing some precision parts, such as the dynamic and static pressure axial end face cavity with high requirements for depth dimension and shape tolerance, the lathe generally does not have the precise adjustment of the depth of the knife, and the manual scraper can only be adjusted to the end by experience and technology, and it is difficult to guarantee the shape tolerance Moreover, the depth of the cavity is not easy to grasp, which also affects the processing efficiency. Contents of the invention [0003] The object of the present invention is to provide a fine-tuning tool holder for a lathe with high precision and high processing efficiency. [0004] The present invention is achieved through the following measures: the fine-tuning tool bar for lathes includes a fixed tool bar, a movable tool bar and...
