Tool changer assembly and machining center

Abstract

The invention discloses a tool changer assembly and a machining center. The tool changer assembly comprises a tool changer. The tool changer comprises a tool changer body and a tool sleeve used for installing a tool; the tool sleeve is rotationally connected to the tool changer body so as to overturn between the tool storing position and the tool changing position; the tool changer assembly further comprises a telescopic mechanism; the fixed end and the telescopic end of the telescopic mechanism are rotationally connected to the tool changer body and the tool sleeve correspondingly through a corresponding rotating pair; when the telescopic mechanism extends / shrinks, the tool sleeve is pushed away from / pulled close to the tool changer body; and meanwhile, each rotating pair works to make the tool sleeve overturn relative to the tool changer body. According to the tool changer assembly, by means of a small-size tool reversing mechanism, a tool reversing block in the prior art is saved, a tool disk is pre-arranged, differenced from a traditional tool changer, the front and back distance is greatly shortened, the center distance between machine tool main shafts is also reduced, the machine tool volume is reduced, the tool changing position is closer to a tool arm, it is easy to reduce the length of the tool arm used in cooperation with the tool changer assembly, and therefore the tool arm structure is optimized.

Description

technical field [0001] The invention relates to the field of machining, in particular to a tool magazine assembly and a machining center with the same. Background technique [0002] Machine tools are often used in the 3C industry, especially the mobile phone parts processing industry, in order to process fine parts, such as turning and milling parts. At present, the mainstream processing machine tools are still single-head machining centers, and multi-head machining centers are not commonly used. [0003] Whether it is a single-head machining center or a multi-head machining center, it includes the following parts: tool magazine, automatic tool change mechanism and tool reverse mechanism. The tool magazine is used for positioning and installing tools. One tool magazine can accommodate multiple tools. The capacity of the tool magazine is directly related to the number of tools that are positioned and installed on it. The automatic tool change mechanism is used to exchange t...

Problems solved by technology

[0007] The existing tool magazine assembly has a tool holder and a knife block set separately along the X-axis direction. The distance between the rotation center of the knife arm and the tool to be replaced is relatively long, and the tool arm that needs to be matched is long. The tool magazine assembly along the X-axis direction The overall size is large and the structure is not compact enough, which leads to the large volume of the machining center using the tool magazine assembly and low structural space utilization
