Abstract

The invention relates to a longitudinal beam hydraulic press displacement detection device, which comprises a stretching-type displacement sensor and an on-site bus interface. One end of the stretching-type displacement sensor is fixedly connected on the lower surface of an upper beam of the hydraulic press; a stay rope outgoing end of the stretching-type displacement sensor is connected with an upper surface of a hydraulic press slide block; and the on-site bus interface forms a communication connection with a controller through the on-site bus. The device provided by the invention is suitable for position detection of the long center longitudinal beam hydraulic press slide block stroke, has advantages of high precision, strong partial load resistance and high defense grade, and is convenient to install.

Description

technical field [0001] The invention belongs to the technical field of hydraulic presses, in particular to a displacement detection device for longitudinal beam hydraulic presses. Background technique [0002] Currently, the table tops of stringer hydraulic presses used in the automotive industry are relatively long, reaching 12 meters. At the same time, due to the stress requirements of various longitudinal beams, there is a large partial load force during the pressing process, which leads to the out-of-tolerance parallelism of the longitudinal beam hydraulic press and needs to be leveled. During the leveling process, the traditional linear displacement sensor sends the detection data to the controller, and the controller judges the eccentric load force of the longitudinal beam hydraulic press. However, due to the limitations of the installation location and its own high-precision linear requirements, it cannot be used in the case of large eccentric loads, and the linear d...
