An automatic tool changer for scissor mechanism and its modular design method

Abstract

The invention relates to an automatic tool changer for a numerical control machining center, in particular to an automatic tool changer for a scissor-fork mechanism and a modularized design method for the automatic tool changer. According to the automatic tool changer for the scissor-fork mechanism, the automatic tool changer comprises a transmission box, mechanical clamping jaws, a telescopic mechanism, a rotating mechanism and a lifting mechanism. The stretching out and drawing back functions of the mechanical clamping jaws are achieved by the telescopic mechanism through the combination of the scissor-fork mechanism and other components, and then the transmission box, the rotating mechanism and the lifting mechanism are matched for achieving rotating, rising and falling of the automatic tool changer. Compared with the prior art, the automatic tool changer for the scissor fork mechanism is compact in structure, has good interchangeability and is suitable for tool changing environments of various machining centers, and modularization, seriation and rapid design can be achieved; the non-cutting time is shortened by shortening tool changing time, and accordingly the working efficiency of the numerical control machining center is improved. The post-maintenance cost of the automatic tool changer can also be reduced due to the good interchangeability of the automatic tool changer.

Description

technical field [0001] The invention relates to an automatic tool changing device of a numerical control machining center, in particular to an automatic tool changing device of a scissor mechanism and a modular design method thereof. Background technique [0002] The automatic tool changer is an automatic device for machining centers used to realize tool transfer and loading and unloading between the machine tool spindle and the tool magazine. According to the tool change method, it can usually be divided into the tool change method with a manipulator and the relative movement between the tool magazine and the machine tool spindle. Tool change without manipulator to complete the tool change action. The automatic tool changer is an important auxiliary device of the CNC machining center. Its main function is to shorten the non-cutting time during the machining process and reduce the labor intensity of the workers. Efficiency and surface processing quality have a certain influ...
