Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a double-sided welding clamping and displacement mechanism. Background Art

[0002] The guardrails on existing railway tracks are mainly used to guide the wheels to move in the correct direction and prevent the wheels from collapsing the top surface of the heart rail. The guardrails wear quickly and have a short life under the repeated friction of the vehicles. When the wear exceeds the limit, they need to be replaced, which wastes a lot of manpower and material resources. If the replacement is not timely, when the wheels cannot be correctly guided to run in the correct direction, it will endanger driving safety. Therefore, wear-resistant metal is generally welded on the side of the guardrail to reduce the wear rate, extend the life of the guardrail, and ensure driving safety. At present, the wear-resistant guardrail is generally welded on both sides of the guardrail body and the alloy steel wear-resistant strip. When welding, the weld on the inner side below is welded first. Before welding, the wear-resistant guardrail body and the wear-resistant guardrail strip need to be positioned and clamped, and then submerged arc automatic welding is performed. After the weld is welded, it needs to be disassembled, turned upside down, and then positioned and clamped for a second time to perform submerged arc automatic welding of the upper weld.

[0003] When welding, it is necessary to weld the upper and lower ends of the joint position, so there are two upper and lower welds. When welding the inner weld, due to the structural limitations of the wear-resistant guard rail, the welding gun and the upper edge of the wear-resistant guard rail body will interfere, and the welding gun cannot weld vertically. If the welding gun is tilted, the position of the molten metal is prone to deviation, and the welding effect is limited, which will affect the forming of the inner weld and even cause undercutting, affecting the welding quality. Utility Model Content

[0004] The disclosed embodiment relates to a double-sided welding clamping and displacement mechanism. During welding, a motor is used to control a flip assembly to flip, and the flip assembly drives the guard rail body and the wear-resistant guard rail and wear-resistant strip to rotate, and perform a certain displacement and tilt to achieve a similar "boat-shaped welding" so that the welding gun is vertically in contact with the weld for welding, thereby achieving the verticality of the welding gun, eliminating undercuts, and ensuring welding quality.

[0005] According to the first aspect of the present disclosure, a double-sided welding clamping and displacement mechanism is provided, which specifically includes: a main body; the top end of the main body is connected to the motor through a bracket, the inner end of the motor is fixedly connected to the flip assembly, and controls the flip assembly to flip freely, a clamping plate assembly is installed on the upper left side of the flip assembly through a rotating shaft, a long groove is provided inside the clamping plate assembly, a second oil cylinder is fixedly installed on the left end of the main body, a third oil cylinder is inserted through the right end of the main body, and the third oil cylinder is installed with an inner rod and an outer rod through a connecting plate.

[0006] In at least some embodiments, two brackets are fixed to the top of the main body, and a motor is fixed above each bracket. The two motors are symmetrically arranged, and a through slot is provided in the middle of the flip assembly; the through slot of the U-shaped flip assembly is penetrated by evenly arranged bottom slots on the left side, and the bottom slots are dovetail-shaped structures; a first oil cylinder is embedded in the left end of the main body, and the top of the first oil cylinder is connected to the push rod assembly, and drives the push rod assembly to move up and down, and the rear end of the push rod assembly is inserted into the interior of the main body for pulling, and the push rod assembly is inserted into the long slot.

[0007] In at least some embodiments, the telescopic end of the second oil cylinder is fixedly connected to the connecting rod, and the bottom end of the connecting rod is fixedly connected to the linkage rod; the side of the linkage rod is provided with evenly arranged contact blocks, and the contact blocks with a dovetail structure are inserted into the inside of the bottom groove and can be freely pulled out.

[0009] The utility model provides a double-sided welding clamping and displacement mechanism, which has the following beneficial effects:

[0010] During welding, the motor controls the flip assembly to flip, and the flip assembly drives the guardrail body and the wear-resistant guardrail and wear-resistant strip to rotate, and perform a certain displacement and tilt to achieve a similar "boat-shaped welding" so that the welding gun can be vertically contacted with the weld for welding, so as to achieve the verticality of the welding gun, eliminate undercuts, and ensure welding quality;
