Lathe gang tool rest installation precision adjusting method

Abstract

The invention provides a lathe gang tool rest installation precision adjusting method. According to the lathe gang tool rest installation precision adjusting method, a targeted gang tool rest structure is designed by analyzing the machining characteristics of lathe holes, and the gang tool rest installation precision adjusting method is formulated according to the structural characteristics and precision of a lathe; by additionally arranging the tool positions on a sliding plate, the machining capacity is improved, the designed gang tool rest installation precision adjusting method is suitablefor increasing the number of the lathe tool positions, the precision obtained through the gang tool rest installation precision adjusting method can meet the precision requirement of a machine tool,the machining precision of a refitted gang tool rest is improved to the maximum extent, rapid tool replacing is achieved, the toolsetting error is eliminated, the production efficiency is improved, the hole machining precision is improved to the maximum extent, and the high-precision and high-efficiency operation requirements of modern production and manufacturing are met.

Description

technical field [0001] The invention relates to the technical field of lathe tool holders, in particular to a method for adjusting the installation precision of a lathe tool holder. Background technique [0002] Due to its low cost, economical CNC lathes are still commonly used by most enterprises and play an extremely important role in my country's manufacturing industry; the four-station automatic rotary tool holder it has always used has simple structure, flexible movements, and repeatable It has high positioning accuracy and has been used on economical CNC lathes, but its processing capacity is severely limited by the number of tool positions. The four-station automatic rotary tool post can only be equipped with four knives under normal circumstances. The rough turning tool, finishing turning tool, threading knife, groove knife or cutting knife are used to process the external contour of the parts, but lack the processing of the internal contour. Capabilities, such as ce...

Problems solved by technology

[0002] Due to its low cost, economical CNC lathes are still widely used by most enterprises and play an extremely important role in my country's manufacturing industry; The four-station automatic rotary tool post has a simple structure, flexible movement, and high repeat positioning accuracy. It has been used on economical CNC lathes, but its processing capacity is severely limited by the number of its own tool positions.

The four-station automatic rotary tool post can only be equipped with four knives under normal circumstances. The rough turning tool, finishing turning tool, threading knife, groove knife or cutting knife are used to process the external contour of the parts, but lack the processing of the internal contour. Capabilities, such as centering positioning holes, drilling, reaming, reaming and turning various internal contours, etc.

However, when such modification is used to make center positioning holes, drill holes, ream holes and ream holes, it is necessary to adjust the tool on the x-axis, y-axis and z-axis at the same time, which is extremely difficult to adjust, and each time a new part is processed or replaced midway All the knives need to be re-adjusted. The workload is heavy, the efficiency is low, and the technical requirements are high. A small adjustment error will directly damage the knives, and the machining accuracy is low, which cannot meet the modern high-efficiency and high-precision manufacturing requirements.
