Two-dimensional displacement tracking mechanism

Abstract

The invention discloses a two-dimensional displacement tracking mechanism and relates to the technical field of heat treatment mechanical equipment. It includes a mounting plate, the first fixing plate and the second fixing plate are respectively fixed on both sides of the mounting plate, the first fixing plate and the second fixing plate are respectively provided with a displacement measurement component and a double cylinder, and the first fixing plate The plate and the second fixed plate are vertically fixed to the mounting plate, and the two displacement measuring components are arranged at an angle of 90°, and are driven and connected with the double cylinder. The invention can realize high-precision measurement of the deformation of the long axis at the same time, and can meet harsh working conditions, and has multiple advantages such as lower cost than the optical sensor compared with the same period.

Description

technical field [0001] The invention belongs to the technical field of heat treatment mechanical equipment, and in particular relates to a two-dimensional displacement tracking mechanism. Background technique [0002] In terms of the demand for CNC quenching machine tools, when the machine tool is quenching, it is necessary to heat and cool the long-axis workpiece. At this time, because the workpiece is heated, the long-axis is bent and deformed. If the sensor scans and quenches according to the original track, the workpiece will not be heated. Uniformity, so a mechanism that can detect the bending direction and deformation of the workpiece is needed, and feed it back to the CNC system. The horizontal two-dimensional direction of the sensor is adjusted by the servo axes in the XY directions to ensure that the center of the sensor is always in line with the workpiece. Concentric, which can improve the uniformity of the quenched layer of the workpiece. [0003] In addition, d...

Problems solved by technology

[0003] In addition, due to the harsh working conditions, there is a lot of oily smoke inside the machine tool, and there is also hot water vapor, which interferes with the general laser sensor and other problems, and when using loading and unloading, the sensor should not be damaged in advance, etc. Restricted conditions, the existing technology is a simple laser sensor, and when in use, this mechanism needs to be withdrawn from the loading position; in addition, the range of deformation is generally relatively small, and high-precision measurement and monitoring cannot be guaranteed
