Four-chain synchronous lifting mechanism applied in laser automatic feeding and discharging system

Abstract

The invention discloses a four-chain synchronous lifting mechanism applied in a laser automatic feeding and discharging system, and belongs to the field of laser cutting conveying mechanism. The four-chain synchronous lifting mechanism applied in the laser automatic feeding and discharging system includes a machine frame, a motor, a driving shaft, a driving chain wheel, a driving shaft lifting chain wheel, a transition chain wheel and a driven shaft. The motor is fixedly connected to the machine frame. The driving shaft is rotationally connected with the machine frame and is connected with a driving end of the motor. The driving chain wheel is fixedly in sleeved connection with the driving shaft. The driving shaft lifting chain wheel is fixedly in sleeved connection with the driving shaft.The transition chain wheel is fixedly in sleeved connection with the driving shaft. The driven shaft is rotationally connected with the machine frame. The four-chain synchronous lifting mechanism applied in the laser automatic feeding and discharging system reduces the material used for lifting tooling of a large surface plate and reduces the production cost of a lifting tool. The lifting area ofthe large surface plate is increased to ensure the production safety. Compared with rack and pinion transmission, the adoption of chain transmission for transmitting power reduces the cost of production; and a condition is provided for automatic machining of the large surface plate.

Description

technical field [0001] The invention relates to the technical field of laser cutting feeding mechanism, in particular to a four-chain synchronous lifting mechanism applied in a laser automatic loading and unloading system. Background technique [0002] With the continuous development and innovation of laser technology at home and abroad, the application of laser cutting technology in actual production is becoming more and more mature, and the cutting of metal materials is even more inseparable from the application of laser cutting technology. There are generally three ways to cut and blank metal sheets : [0003] One is shearing and blanking with a shearing machine. In this blanking method, the cutting surface of the sheet is rough, the incision is uneven, and the shape of the cutting blank is single; [0004] One is plasma cutting blanking, which has a rough cutting surface and can cut sheets with complex shapes; [0005] One is laser cutting blanking. The cutting surface...

Problems solved by technology

[0006] In the process of metal sheet cutting, the transportation and loading and unloading devices of sheet metal are essential. At present, sheet metal is generally transported in stacks, and the specifications are standard. The sub-size of sheet metal is generally 3000*1500mm, 4000mm *2000mm, 6000*2000mm, when the metal sheet is transported in a single sheet, it is generally carried by manual handling, driving and vacuum suction cup frame for lifting, and automatic loading and unloading system; but these handling methods are not suitable for the metal sheet transportation of the large plate pair Due to the large size of the board and the huge and cumbersome lifting equipment, it cannot be perfectly applied in the advanced process equipment such as automatic loading and unloading. Therefore, an automatic four-chain synchronous lifting mechanism is particularly important.
