Welding material taking mechanical arm

Abstract

The invention discloses a welding material taking mechanical arm which comprises a machine base, a motor, a connecting rod, a hanging arm, a connecting block, an air cylinder, a pneumatic finger, pneumatic pipelines and a solenoid directional valve. The connecting rod is vertically arranged on the machine base. The bottom of the connecting rod is in transmission linkage with the motor. The top of the connecting rod is provided with the hanging arm. The end portion of the hanging arm is hinged to the connecting block. One end of the connecting block is provided with the pneumatic finger. A clamping block of the pneumatic finger is made of heat-resisting materials. The air cylinder used for driving the connecting block to turn is connected between the other end of the connecting block and the hanging arm. The air cylinder and the pneumatic pipeline are connected with the solenoid directional valve through the pneumatic pipelines. The welding material taking mechanical arm has the advantages of being simple in structure, high in cost-effectiveness ratio and the like.

Description

technical field [0001] The invention relates to a robot device, in particular to a welding and retrieving manipulator. Background technique [0002] Welding is the process of forming a permanent connection by applying heat or pressure or both to different workpieces to achieve interatomic bonding. The workpiece will heat up significantly during the welding process. Even after the welding is completed, there is still considerable heat on the surface of the workpiece. The operator needs to wear heat-resistant gloves or use clamps to remove the welded workpiece from the tooling. The speed is slow, the efficiency is low, and the delay in retrieving materials makes the welding work of batch workpieces intermittent. The temperature of the welding machine and the solder is cycled between a sudden rise, cooling and rising, which is likely to cause poor consistency of batch welded workpieces. defect. However, the current manipulator device is relatively complex, usually with mu...

Problems solved by technology

The workpiece will heat up significantly during the welding process. Even after the welding is completed, there is still considerable heat on the surface of the workpiece. It is necessary for the operator to wear heat-resistant gloves or use clamps to remove the welded workpiece from the tooling. The speed is slow, the efficiency is low, and the delay in retrieving materials makes the welding work of batch workpieces intermittent. The temperature of the welding machine and the solder is cycled between a sudden rise, cooling and rising again, which is likely to cause poor consistency of batch welded workpieces. defect

However, the current manipulator device is relatively complex, usually with multiple servo motors or cylinders installed in different motion directions, resulting in long motion trajectory and slow speed, and the cost of high-precision sensors and control centers for processing calculations is high. , not suitable for use in the occasion of welding and retrieving materials
