A three-coordinate measuring machine safety position signal acquisition device and method

Abstract

The present invention relates to a safety position signal acquisition device and method of a three-coordinate measuring machine. The acquisition device includes: a pluggable plug connected to a controller of the three-coordinate measuring machine; a relay module comprising a first relay, a second The relay and the third relay, the mapping channels corresponding to the X-axis, Y-axis and Z-axis of the CMM are respectively connected to the power supply ends of the coils of the first relay, the second relay and the third relay, the first relay, the second relay and the normally closed static contact in the two conversion contacts of the third relay are connected in turn with the normally open static contact in the remaining one conversion contact; the acquisition device has a collection positive terminal and a collection negative terminal, and the collection positive The terminal is connected with any movable contact of the two changeover contacts, and the collection negative end is connected with the moveable contact of the remaining one changeover contact. The invention is used to automatically collect the safety position signal of the measuring machine by modifying the parameters of the measuring machine controller, so as to improve the use safety of the measuring machine.

Description

technical field [0001] The invention belongs to the technical field of three-coordinate measuring machines, and in particular relates to a safety position signal acquisition device and method of three-coordinate measuring machines. Background technique [0002] The current automatic control system relies on the sensor to realize the safe position signal acquisition of the three-coordinate measuring machine. The sensor bracket needs to be designed according to different equipment requirements to fix the sensor, and it is necessary to find a suitable installation position to avoid the work position. [0003] For the detection of the existing three-coordinate measuring machine, sensors are generally installed on the X-axis and Y-axis to detect the position of the X-axis and the Y-axis. This detection method is used to determine whether the three-coordinate measuring machine is in a safe position, but due to structural reasons The sensor cannot be installed on the axis, and the...

AI Technical Summary

Problems solved by technology

[0005] (1) Installation is inconvenient. Different mechanisms need to design different sensor brackets and the installation position and fixing method need to be considered, resulting in inconvenient installation;

[0006] (2) It is not easy to adjust, the wiring is inconvenient and not beautiful, and sometimes it is necessary to punch holes in the measuring machine, which is not only not beautiful, but may also affect the original performance of the measuring machine;

[0007] (3) After the three-coordinate measuring machine completes the operation of returning to the origin each time, the operator needs to manually control the control box to move the measuring machine to a safe position. In order to ensure that the measuring machine can be moved to a safe position, the detection range of the sensor will be set The relatively wide range leads to the inability to accurately confirm the initial safe position and increases the amount of manual tasks;

[0008] (4) The operator needs to know how to operate the measuring machine, which increases the difficulty of the operator
