Guardrail plate automatically welding device

Abstract

Disclosed is a guardrail plate automatically welding device. The guardrail plate automatically welding device comprises a pressing wheel, a wheel seat, a jacking device and a displacement sensor. The wheel seat is provided with the pressing wheel; the jacking device comprises an oil cylinder or steam cylinder; the bottom of the wheel seat is connected with the jacking device; the displacement sensor is connected with the piston of the oil cylinder or steam cylinder or the wheel seat. According to the guardrail plate automatically welding device, force exerted on the pressing wheel by the oil cylinder or steam cylinder can keep the same, so that pressure between the pressing wheel and a ring piece has no significant change, the problem that the quality of the ring piece is affected by overhigh pressure of the pressing wheel can be voided; the displacement of the pressing wheel can be obtained through accurate measurement of an encoder, so that the measuring precision can be effectively improved, and errors can be effectively reduced.

Description

technical field [0001] The invention relates to a welding device, in particular to an automatic welding device for fences. Background technique Due to the thinner thickness and more bends of the semi-trailer sideboard, the welding seam tracking requirements are relatively high during welding, and the weld seam will be welded through if there is a slight deviation. In addition, due to the change of welding speed between the straight side and the beveled side, and the rotation control of the welding torch on the beveled side, the difficulty of controlling the equipment is increased. Therefore, automatic welding cannot be realized in the welding of similar equipment. Since the above-mentioned problems are difficult to solve so far, at present, all the side panels of semi-trailers are welded manually, resulting in high labor intensity for welders, low welding efficiency, and difficult to guarantee welding quality. Contents of the invention In order to solve the above probl...

Problems solved by technology

In addition, due to the change of welding speed between the straight side and the hypotenuse, and the rotation control of the welding torch on the hypotenuse, the difficulty of controlling the equipment is increased. Therefore, automatic welding cannot be realized in the welding of similar equipment.

Since the above problems have been difficult to solve so far, all semi-trailer railings are currently welded manually, resulting in high labor intensity for welders, low welding efficiency, and difficult to guarantee welding quality.
