Tool mechanism for clamping frame workpiece of robot workstation

Abstract

The invention discloses a tool mechanism for clamping a frame workpiece of a robot workstation. The mechanism comprises frame workpiece supports matched with the frame workpiece, wherein frame positioning blocks matched with workpiece frames are arranged on four frame supports; ejection air cylinders are arranged on inner sides of the frame positioning blocks; ejection rods of the ejection air cylinder are ejected, so that four frames of the frame workpiece are fixed and positioned stably in positions corresponding to the frame positioning blocks; and workpiece ejection mechanisms are arranged corresponding to the frames of the frame workpiece on the frame supports. The tool mechanism for clamping the frame workpiece of the robot workstation is ingenious and reasonable in structure; and the four scattered frames of the frame workpiece are directly positioned and fixed on the frame workpiece supports through arrangement of the ejection air cylinders and the frame positioning blocks, so that a complex underneath electric welding process in which positioning errors are prone to occur is not required, the workpice supports can be directly fixed and welded, the work efficiency is greatly improved, and the work errors are also greatly reduced.

Description

technical field [0001] The invention relates to a tooling mechanism, in particular to a tooling mechanism for a robot workstation. Background technique [0002] In the prior art, frame-type welding workpieces (i.e. frame-type workpieces, such as figure 1 The one shown is a frame-shaped typical workpiece) is a relatively special type of workpiece with a large variety and quantity. In the traditional process, spot welding is performed on the main joints of the frame-shaped workpiece in advance to form a After completing the frame structure, it is fixedly installed on the workbench of the robot workstation for welding. The whole process is complicated, and the positioning of each component in the spot welding process is also a troublesome problem. [0003] And when it is installed on the workbench of the robot workstation, manual adjustment and manual positioning are usually used. This positioning method has a large human factor and the quality is not stable enough. Contents...
