Abstract

The invention discloses a tool changing error detection prewarning device for a machining centre in the technical field of machining. The tool changing error detection prewarning device comprises a prewarning system, a compensating system, a tool loading brake switch, a displacement sensor, a brake block, a tool unloading brake switch, a magnetic base and a connecting rod, wherein the displacement sensor is fixedly connected with the magnetic base to transmit tool change errors of the machining centre to the prewarning system, the prewarning system is arranged on the magnetic base and connected with the tool loading brake switch and the compensating system to transmit tool changing error prewarning decision information of the machining centre, the tool loading brake switch is connected with the magnetic base to brake a tool changing mechanism of the machining center, the compensating system is connected with the base to transmit a tool changing error compensating strategy, and the brake block and the connecting rod are fixedly connected and move simultaneously to trigger the tool loading brake switch for realizing tool changing error hard braking.

Description

technical field [0001] The invention relates to a device in the technical field of machining, in particular to a tool change error detection and early warning device for a machining center. Background technique [0002] The CNC machining center has the characteristics of high precision, high flexibility, and high automation. It is widely used in the manufacture of box parts and molds. It is superior to ordinary CNC milling machines because of its automatic tool change function (ATC). However, when the machining center automatically changes the tool, the stroke of the plunger bolt will continue to shorten under the action of impact force and torsion force, resulting in tool change errors. Even if the cylinder pressure and cylinder piston stroke are normal, it is difficult to expand the tool circlip and remove the tool. Since the machining center cannot detect the stroke of the punch rod when changing the tool automatically, let alone detect whether the tool clip spring is fu...
