Description

Welding gun carrier

Technical Field

The utility model relates to a welding equipment especially relates to a welder carrier.

Background

The welding process needs to use equipment such as a welding machine, and the equipment is usually placed on the wheel type chassis, but the gas storage tank is not protected for convenient movement; for example, a "welding machine loading cart" disclosed in chinese patent document, publication No. CN204381644U, includes a chassis and wheels disposed below the chassis, and the chassis of the cart is provided with two partitions, namely a first partition and a second partition, which are a gas cylinder placing area and a welding machine and wire reel storage device placing area. According to the scheme, the gas storage cylinder and other equipment are respectively arranged on the trolley, the gas storage cylinder is exposed and lacks external impact protection, and according to the design, if the external shell protection is simply increased, the weight is increased too much, and the moving difficulty is caused.

Disclosure of Invention

The utility model relates to an overcome the exposed problem of lacking the protection of placing of gas bomb of current welder carrier, provide a welder carrier, under the too much condition of avoiding increasing weight, increase crashproof protection for the gas bomb.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a welder carrier, includes the frame and is located the rim plate that is used for coiling welder gas circuit pipeline on the frame, the rim plate rotates the department and is equipped with the cavity structure, be equipped with the gas bomb in the cavity structure and hold the chamber, the gas bomb holds chamber and frame fixed connection, rim plate and gas bomb hold and rotate between the chamber and be connected, are equipped with clockwork spring reset mechanism and bolt locking mechanism on the rim plate. This scheme will be used for coiling welder gas line's rim plate and arrange the gas bomb in and hold the chamber outside, play the guard action to the gas bomb. The wheel disc has a certain rigid structure, and after the welding gun gas path pipeline is wound on the wheel disc, the flexible material of the welding gun gas path pipeline can also protect the gas storage cylinder, so that the gas storage cylinder is prevented from being collided in a factory environment. The effect of clockwork spring canceling release mechanical system is conveniently retrieving welder gas circuit pipeline, when drawing welder gas circuit pipeline and using, truns into the shutting state with blocked mechanical system state, and the rim plate is died by the lock this moment, can not withdraw welder gas circuit pipeline in the effect of clockwork spring canceling release mechanical system down antiport.

Preferably, the clockwork spring reset mechanism comprises a clockwork spring, the clockwork spring is positioned between the cavity structure and the gas storage bottle accommodating cavity, one end of the clockwork spring is fixed on the outer wall of the gas storage bottle accommodating cavity, and the other end of the clockwork spring is fixed on the inner wall of the wheel disc cavity structure. The clockwork spring coils between the outer wall that cavity structure and gas bomb held the chamber, its one of them tip that is located clockwork spring inner circle is fixed at gas bomb appearance chamber outer wall, because the gas bomb holds the chamber and is fixed with the frame, therefore this one end of clockwork spring is the fixed point, when the rim plate rotates, cavity structure drives the end of the outer lane of the french spring of being connected with its inner wall, clockwork spring takes place the elastic torsion, when the external force that stimulates welder gas circuit pipeline disappears, clockwork spring resumes original form and reverse torsion, drive rim plate reverse rotation, withdraw welder gas circuit pipeline gradually.

Preferably, a rotating bearing is arranged between the cavity structure and the gas storage bottle cavity. The inner ring of the rotating bearing is fixed with the outer wall of the gas storage bottle cavity, and the outer ring of the rotating bearing is fixed with the inner wall of the cavity structure, so that the rotating bearing is supported between the wheel disc and the gas storage bottle cavity, when the wheel disc and the gas storage bottle cavity rotate relatively, the rotating friction force of the rotating bearing is reduced, and a spring can be conveniently withdrawn from a welding gun gas circuit pipeline.

Preferably, the bolt locking mechanism comprises a bolt and a spring, a screw hole is formed in the inner wall of the accommodating cavity of the gas storage bottle, the bolt penetrates through the screw hole, the head of the bolt is located in the accommodating cavity of the gas storage bottle, a supporting plate is arranged at the other end of the bolt, and the spring is arranged between the supporting plate and the outer wall of the accommodating cavity of the gas storage bottle. The main effect of the bolt is that the wheel disc is tightly pressed by the bolt when the welding gun works, and the locking effect is achieved on the wheel disc through the friction between the bolt and the inner wall of the cavity structure, so that the reverse torsion of the French spring is avoided, and the wheel disc is retracted into a welding gun gas circuit pipeline. The spring plays the pressure effect, avoids when the bolt is not hard up, and the frictional force of bolt and cavity structure inner wall is not enough, and the shutting that causes is inefficacy.

Preferably, the number of the rotating bearings is two, and the rotating bearings are respectively positioned close to the end faces of the two sides of the wheel disc. The two rotating shafts play a supporting role and are respectively positioned at the end faces of the two sides of the wheel disc, so that the phenomenon that the wheel disc is stressed unevenly when the width of the wheel disc is too large is avoided.

Preferably, the spring is located at the axial centerline of the disc. The spring is a power source when the gas circuit pipeline of the welding gun is retracted, so that the spring is centrally arranged at the axial center line of the wheel disc, and the spring gives the same elastic force to the two ends of the wheel disc.

Preferably, a pair of wheels is arranged below the frame, and a support rod for parking is arranged at the edge of the frame. A pair of wheels effectively shortens the length of the inner frame and facilitates turning. The support rod is fixed at the lower part of the frame, the length of the support rod does not influence the movement of the carrier when the frame is in a horizontal state, the support rod mainly has the function of matching with wheels to provide a fulcrum when the carrier is parked, and when the carrier needs to be parked, the support rod can be grounded only by inclining the frame.

Therefore, the utility model discloses following beneficial effect has: (1) the wheel disc wound around the gas circuit pipeline of the welding gun is arranged outside the cavity of the gas storage bottle, so that the gas storage bottle is protected, and the additional structural weight is not greatly increased; (2) the clockwork spring can automatically retract into a welding gun gas path pipeline when needed; (3) the pair of wheel matching supporting rods is arranged, so that the vehicle can turn conveniently, and the vehicle length is shortened.
