Tool changing tool position detecting mechanism and linear driving mechanism

Abstract

The invention discloses a tool changing tool position detecting mechanism. The mechanism comprises a sliding seat, a connecting rod and a detection air channel, wherein a non-sealed detection chamberis arranged on the sliding seat; the connecting rod is connected with a tool claw of a tool changing manipulator, and a sliding block slidably matched in the detection chamber is arranged on the connecting rod; and the detection air channel communicates with the detection chamber, and when the tool claw drives the connecting rod to slide on the sliding seat, the sliding block blocks or releases the detection air channel. According to the tool changing tool position detecting mechanism, the detection chamber is arranged on the sliding seat, and the detection air channel communicates with the detection chamber, so that when the tool claw drives the connecting rod to slide on the sliding seat, the sliding block blocks or releases the detection air channel; and through the air pressure condition of the detection air channel, the position of the tool claw is judged, the working state of the tool claw is determined, and whether a tool is clamped by the tool claw is judged. The invention further provides a linear driving mechanism with the detecting mechanism.

Description

technical field [0001] The invention relates to the technical field of machine tool processing, in particular to a tool change tool position detection mechanism and a linear drive mechanism. Background technique [0002] When machining complex workpieces with CNC machine tools, multiple tools may be required for machining. In order to store multiple tools, CNC machine tools need to be equipped with tool magazines. The tool magazine with automatic tool change needs to be equipped with an automatic tool change mechanism. [0003] In the tool changing mechanism currently on the market, after long-term operation of the tool changing manipulator, the parts will be worn and the claws will be stuck, which is prone to unstable tool clamping. In the existing tool change mechanism technology, there is a lack of effective detection means to detect whether the tool is clamped in place. Before the tool change rotation action, the existing tool change mechanism cannot judge whether the ...

Problems solved by technology

[0003] In the tool changing mechanism currently on the market, after long-term operation, the tool changing manipulator will cause wear of the parts and jamming of the claws, which is prone to unstable tool clamping.

In the existing tool change mechanism technology, there is a lack of effective detection means to detect whether the tool is clamped in place. Before the tool change rotation action, the existing tool change mechanism cannot judge whether the tool is clamped, resulting in Knives are easy to fly out of the claws, causing safety accidents

[0004] Moreover, the current tool change mechanism generally automatically locks the tool through an elastic telescopic mechanism. During the process of the tool arm rotating and automatically clamping the tool, the claws of the tool arm will collide with the tool. Due to the design of the spring, the instantaneous impact force will be relatively large, and at the same time , the impact force will be transmitted to the machining spindle through the tool

In this way, when the equipment is working, the long-term tool change action will cause repeated impacts on the processing spindle, which may cause the processing spindle to deviate or damage the processing spindle, and affect the machining accuracy of the processing spindle tool
