How to Adjust the Installation Accuracy of Lathe Tool Holder

Abstract

The adjustment method of the installation accuracy of the lathe tool holder, through the analysis of the characteristics of the lathe hole processing, design the targeted structure of the tool holder, and formulate the adjustment method of the installation accuracy of the tool holder according to the structural characteristics and accuracy of the lathe itself; Adding tool positions expands the processing capacity. The designed adjustment method for the installation accuracy of the tool holder is suitable for the increase in the number of lathe tool positions. The accuracy obtained by the installation accuracy adjustment method can meet the accuracy requirements of the machine tool itself, and the maximum It improves the processing accuracy of the modified tool holder, realizes quick tool change, eliminates tool adjustment errors, improves production efficiency, and maximizes the accuracy of hole processing. It is suitable for high-precision and high-efficiency operation requirements of modern manufacturing.

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.
