High reliability multifunctional welding machine clamping device

Abstract

The invention relates to a high reliability multifunctional welding machine clamping device. The device comprises a base, a fixed clamping table, a lifting and moving clamping table, two driving hydraulic cylinders, a centering mechanism, first and second pressure detecting members and a controller, and two guiding rods are arranged on the base; the fixed clamping table horizontally protrudes fromthe upper end of the front side of the base, a first groove is formed in the outer side of the upper end surface, and a front lining plate is embedded inside the first groove; a second groove is formed in the rear side of the upper end surface of the base, and a rear lining plate is embedded in the second groove; the lifting and moving clamping table is slidably disposed on two guiding rods; cylinder bodies of the two driving hydraulic cylinders are arranged on both sides of the lifting and moving clamping table, and the ends of piston rods are connected to the tops of the guiding rods; the centering mechanism is arranged in a guide groove of the lifting and moving clamping table; the first and second pressure detecting members are arranged under the front and rear lining plates; the driving hydraulic cylinders, a lifting hydraulic cylinder, a pressing hydraulic cylinder, a centering hydraulic cylinder, a displacement detector and the first and second pressure detecting members are all connected to the controller. The device overcomes the problems that an original welding machine is affected by the rubbing of a strip steel plate (edge waves, medium waves and the like) so that a strip steel cannot be effectively clamped, which affects the quality of a weld seam, and deviations easily occur to affect the welding reliability.

Description

technical field [0001] The present invention relates to welding equipment, in particular to a high-reliability multi-functional welding machine clamp device, which is suitable for plate clamping and anti-sequencing and self-prevention during the welding process of laser welding machines for high-speed pickling and cold rolling mills. damage. Background technique [0002] The cold-rolled acid tandem mill adopts a laser butt welding machine. During the welding process of the welding machine, the strip to be welded must be reliably clamped. Due to the influence of rubbing, the jaw liner of the clamp is prone to wear and the strip steel cannot be clamped effectively, and the unclamped abnormality cannot be found in time to affect the quality of the weld. At the same time, in order to realize the entrained steel in the middle of the clamp A camera centering device is installed on the back of the clamp. The centering speed is relatively slow and deviations are prone to affect wel...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to design a kind of high-reliability multifunctional welding machine clamping device, has overcome original welding machine owing to being affected by the rubbing influence of strip plate type (edge ​​wave and middle wave etc.), the jaw liner plate of clamp is easily damaged. Wear and tear caused the strip steel to be unable to be effectively clamped, and the unclamped abnormality could not be detected in time to affect the quality of the weld. At the same time, the independent camera centering device installed on the rear side of the original clamp has a relatively slow centering speed and is prone to deviation Problems affecting welding reliability
