High-precision rapid positioning device for automatic production line

Abstract

The invention discloses a high-precision rapid positioning device for an automatic production line. The high-precision rapid positioning device is composed of a moving device, a guide mechanism, a position detection sensor, a sensor trigger block, a fixed supporting plate, a concave positioning block, a concave positioning groove, a transmission assembly and a ground fixing base, the position detection sensor is arranged on the moving device, moreover, whether the moving device reaches the target position or not is detected and judged through the sensor, after the moving device reaches the pre-stop position, the position detection sensor sends a feedback signal to automatically control the moving device to stop moving so as to realize one-time automatic positioning, the transmission assembly adopts an air cylinder as a driving element, a linear bearing is used for reducing the movement gap of a guide shaft, the guide shaft rolls in the linear bearing in an interference fit mode, no radial gap exists, the air cylinder pushes the concave positioning block to be in coaxial fit with the concave positioning groove to be rapidly positioned in the moving direction of the moving device ina high-precision mode. The high-precision rapid positioning device has the characteristics of being high in automation degree, reliable in positioning and good in guiding performance.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing and assembly technology, in particular to a high-precision fast positioning device used in an automated production line. Background technique [0002] Automated and intelligent production workshops are developing rapidly, and material transportation is an important part of the production process. At present, the mobile device for material transportation is equipped with a guide structure. When entering the station, it only needs to be positioned along the moving direction to improve the accuracy and stability of the operation. Generally, limit switches and limit stops are used for positioning. However, the existing methods have problems such as low positioning accuracy, poor reliability, and easy shaking during operation. It is difficult to ensure high-precision and reliable positioning of the mobile device along the moving direction. Simple, fast and accurate high-precision posi...
