Press sliding block detection device, detection method and press

Abstract

The invention provides a press sliding block detection device, detection method and press, and belongs to the field of press position detection. The press sliding block detection device includes a sliding block mechanism, a main shaft, a supporting piece, a rotating piece and a detection mechanism. The main shaft is connected with the sliding block mechanism, so that the main shaft and the slidingblock mechanism synchronously move, and a tooth part is arranged along a length direction of the main shaft; and the rotating piece is rotatably supported by the supporting piece and is in transmission connection with the tooth part of the main shaft. The detection mechanism is configured to detect rotation data of the rotating piece and convert the rotation data into digital data. Data of the position, speed and acceleration of the press sliding block mechanism can be detected through the rotation data. The press sliding block detection device can solve the technical problem existing in theprior art that measured data of the press sliding block position, speed and acceleration are low in precision, realize interlocking of related data of a press automatic device, and effectively improveworking stability and safety of the press.

Description

technical field [0001] The invention relates to the field of position detection of a press, in particular to a detection device and method for a slider of a press and a press. Background technique [0002] With the rapid development of my country's manufacturing industry, stamping technology is widely used in machinery, automobiles, equipment and other fields. As an important part of the stamping automation system, the position, speed and acceleration detection technology of the slider in the stamping process has been paid more and more attention. [0003] The crankshaft in the traditional press is arranged horizontally, and the connecting rod mechanism is respectively connected to the crankshaft and the slider. The rotation of the crankshaft drives the movement of the connecting rod mechanism, which in turn drives the slider to move up and down. The rotary encoder is generally installed on the crankshaft. When the traditional press detects parameters such as the position, ...
