Upper beam mounting bracket of safety light curtain, and angle adjusting base

Abstract

The invention provides an upper beam mounting bracket of a safety light curtain, and an angle adjusting base, and belongs to the field of machining equipment. The upper beam mounting bracket comprises a bracket fixing base, a cross beam, a vertical beam and four adjusting blocks, wherein the cross beam is fixedly connected with the bracket fixing frame; the vertical beam is connected with the cross beam through a rail mechanism and a locking mechanism; the first adjusting block is fixed on the vertical beam; the second adjusting block is hinged with the first adjusting block through a first rotating shaft; the third adjusting block is hinged with the second adjusting block through a second rotating shaft; the fourth adjusting block is hinged with the third adjusting block through a third rotating shaft; and the fourth adjusting block is provided with a fixing position. The upper beam mounting bracket of the safety light curtain can easily realize left-and-right position movement, up-and-down position movement, up-and-down angle adjustment, left-and-right angle adjustment and front-and-back angle adjustment of a light curtain emitter or a light curtain receiver, is high in adjusting freedom degree, and can simplify mounting operation of the light curtain emitter and the light curtain receiver.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to an upper beam installation bracket and an angle adjustment seat of a safety light curtain. Background technique [0002] Safety light curtain, also known as safety grating, punch protector, infrared safety protection device, etc., is a photoelectric safety protection device. In modern factories, people and machines work together. In mechanical transmission and handling equipment, various machining lathes, and hazardous areas such as poisonous, high pressure, and high temperature, which are likely to cause personal injury to workers, safety light curtains are required. [0003] The safety light curtain is mainly composed of a light curtain transmitter and a light curtain receiver. The light curtain transmitter emits infrared rays or lasers, and the photosensitive unit of the light curtain receiver receives the infrared rays or lasers to form a gap between the light c...
