A large-size variable-diameter robotic fixture for processing pipe pile end plates

Abstract

The invention provides a large-size variable-diameter robot clamp used for processing tubular pile end plates. The clamp mainly comprises a base, a linear position-changing mechanism, a clamping mechanism, a positioning mechanism and a dustproof mechanism. The linear position-changing mechanism is driven by a servo motor so that the automation degree of working of the clamp can be improved, and meanwhile, a ball screw and a linear slide rail are integrated so that high-precision large-size position changing of the clamp can be achieved. An electric permanent magnet mode is adopted by the clamping mechanism so that the tubular pile end plates can be clamped rapidly, efficiently, stably and reliably. The positioning mechanism guarantees precise actions and operation safety of the clamp through limit switches. The dustproof mechanism is provided with telescopic protecting sleeves so that a good working environment in the clamp can be ensured. The large-size variable-diameter robot clamp can meet the requirement for efficiently and reliably clamping the tubular pile end plates of various size specifications in robot automatic processing.

Description

technical field [0001] The invention belongs to the field of pipe pile end plate processing, and relates to a large-size variable-diameter robot clamp used for pipe pile end plate processing. Background technique [0002] Pipe pile end plates are widely used at both ends of high-strength prestressed cement pipe piles, and are indispensable ring-shaped metal components. Due to the various requirements of prestressed cement pipe piles and the huge difference in individual size, the diameter of the pipe pile end plate varies greatly. When performing robot welding, handling and testing operations on pipe pile end plates, the end plate clamps can be divided into two types: radial clamping and end clamping according to different clamping methods. These two types of clamps respectively realize the radial or surface pressure on the end plate of the pipe pile through the pneumatic chuck and the mechanical pressing device, so as to achieve the purpose of clamping. However, due to th...

Problems solved by technology

[0004] Aiming at the deficiencies of the existing processing technology, the present invention provides a clamp used for welding, transporting and testing the end plate of the pipe pile by the robot. The clamp adopts an electronically controlled permanent magnet to clamp the surface of the end plate of the pipe pile , and the linear displacement mechanism drives the movement of the clamping device to achieve large-scale precise displacement. The limit switch is used to position the slider, start the origin and prevent the stroke from exceeding. The internal working environment of the fixture is protected by the dust-proof device. The clamping of different types of pipe pile end plates solves the problems of frequent clamp replacement and low automation
