Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a three-dimensional rapid tool changing device for a processing center. Background Art

[0002] In processing and production, the selection of tools is very important. In order to make the turning tool perform good cutting on the lathe, it is crucial to correctly prepare and select the tool. Different cutting tasks require turning tools of different shapes, and cutting different materials requires different blade angles. Therefore, how to choose a turning tool is one of the factors that need to be considered in the use of the turning tool. In the process of machining parts, the machine tool needs to spend a lot of time on changing the tool. In order to shorten the non-cutting processing time and improve the degree of automation of the machine tool, CNC machine tools are developing in the direction of completing multiple processing steps in one clamping. In this type of multi-process CNC machine tool, there must be an automatic tool changer. The machining center is one of the most used equipment in modern mechanical processing, and the automatic tool changer, as the core component of the machining center, has been in continuous improvement. The rapid tool change technology has become an important part of the high-speed machining center technology, aiming to shorten the tool change time and comprehensively improve the cutting efficiency of the machining center on the basis of accuracy and reliability.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN 211991983 U discloses a rapid tool changing device for a machining center, which realizes tool changing by driving the cutter disc to rotate through a motor, eliminating a series of complex operations such as manual loosening, clamping, unloading, loading and tool handling, thereby shortening the tool changing time. However, with the increasing complexity of machined parts, the number of tools installed in the existing back-end tool module can no longer meet the processing of related parts. At the same time, when the machining center is processing, the debris generated during processing may damage the tool on the tool holder, thereby affecting subsequent use. Therefore, it is necessary to design a three-dimensional rapid tool changing device for a machining center. Utility Model Content
