Abstract
The invention belongs to the field of hydraulic press slider detection, and particularly relates to a hydraulic press slider detection device and a detection method thereof. The device comprises displacement sensors arranged beside a hydraulic press slider, the at least two displacement sensors are arranged around the hydraulic press slider at intervals, and the signal output ends of the displacement sensors are connected with a computer. Each displacement sensor is used for detecting the height and movement speed of the corresponding part of the edge of the hydraulic press slider. The computer samples and calculates the detection data of the displacement sensors to obtain the average value of the detection data of the displacement sensors, and the average value is the actual height and actual speed of the center of the hydraulic press slider. According to the invention, the multiple displacement sensors are adopted to measure multiple positions around the hydraulic press slider, then, the average of measurement results is calculated, and further, the actual position and movement speed of the center of the hydraulic press slider are obtained. The influence of slider tilting on the accuracy of slider position and speed measurement is eliminated.

Background technology
Hydromechanical deep drawing hydraulic press requires that the position control accuracy of speeds control and slide block is high, and the precision of the position and speed of therefore measuring its center also requires very high.The measurement of its speed goes out the displacement of slide block within the unit interval by displacement sensor to obtain.Because slide block Center of Pressure in operational process changes always, cause slide block changing with the depth of parallelism of worktable in operational process always.Again due to can not position in the middle part of direct-detection slide block and speed by installation site limiting displacement sensor, hydropress of the prior art is by detecting the position of a certain position, slide block edge as its center, this method, by the impact of the slide block depth of parallelism, is not suitable for hydro-mechanical drawing technique to position and the high-precision requirement of velocity measuring.
Summary of the invention
The object of this invention is to provide a kind of slider tilt of can eliminating to the slider of hydraulic press pick-up unit of slide position and velocity survey Accuracy and detection method thereof.
For achieving the above object, the invention provides following technical scheme: a kind of slider of hydraulic press pick-up unit, comprise the displacement transducer for detecting slider of hydraulic press speed and position that slider of hydraulic press side is arranged, institute's displacement sensors is at least provided with two, each displacement transducer is arranged along slider of hydraulic press ambient separation, and the signal output part of each displacement transducer is connected with computing machine.
Present invention also offers a kind of detection method applied said apparatus and carry out detecting: each displacement transducer detects height and the movement velocity at each position, slider of hydraulic press edge respectively; The detection data of computing machine to each displacement transducer are carried out sampling and are calculated, and obtain the mean value that each displacement transducer detects data, this mean value is true altitude and the actual speed at slider of hydraulic press center.
Technique effect of the present invention is: adopt multiple displacement transducer to measure multiple positions of slider of hydraulic press periphery respectively, then the mean value of each measurement result is calculated, and then obtain physical location and the movement velocity at slider of hydraulic press center, eliminate the impact of slider tilt on slide position and velocity survey precision.
