Embodiment Construction

[0048] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings:

[0049] Such as Figure 1 to Figure 7 As shown, a tool 2 locking device of a five-axis machining center includes a main shaft 1 and a tool 2 installed on the main shaft 1. The main shaft 1 is provided with an inner cavity 11, and the inner cavity 11 is provided with a locking device and a driving device, the driving device drives the locking device to operate the locking tool 2, and the driving device includes a pressure medium device. The tool 2 is inserted into the inner cavity 11 of the main shaft 1, and a locking device is arranged in the inner cavity 11. When the tool is changed, the tool 2 is inserted into the inner cavity 11 and then locked by the locking device to prevent the tool 2 from falli...

Abstract

The invention discloses a numerical control machine tool, and particularly relates to a tool locking device of a five-axis machining center and a tool changing method of the tool locking device. The tool locking device comprises a main shaft and a tool installed on the main shaft, an inner cavity is formed in the main shaft, a locking device and a driving device are arranged in the inner cavity, and the driving device drives the locking device to act to lock the tool. The driving device comprises a pressure medium device, the locking device comprises a first locking part and a second locking part, the locking effect on the tool can be enhanced through the two locking parts, when one locking part loses efficacy, the other locking part still locks and fixes the tool, and the tool can be prevented from falling off.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a tool locking device of a five-axis machining center and a tool changing method thereof. Background technique [0002] The tool is installed on the main shaft of the machining center, and the tool is designed as a replaceable structure, so that the machining center can realize different processing methods by changing the tool, and perform precision machining on the workpiece. [0003] The Chinese invention patent with the application number 201480083399.2 discloses an automatic tool changer for CNC machine tools. The tool changer arm picks up the tool from the tool magazine and the spindle and rotates through 180° to complete the tool position exchange. After that, the spindle needs to be replaced After the tool is locked, it can be processed. [0004] The Chinese invention patent with the application number 201680036465.X discloses a tool sp...
