Abstract
The invention relates to a grounding method and a grounding device used for cylinder girth welding, belonging to the technical field of welding production. The technical scheme is as follows: a rolling block (1), a support rod (2), a guide sleeve (3) and a spring (5) are provided; the rolling block is arranged at the top of the support rod; the tail part of the support rod is arranged inside the guide sleeve; and the guide sleeve is internally provided with the spring so as to compress the support rod inside the guide sleeve. A cylinder (6) rotates on a roller support (7), the rolling block of a grounding device (8) rotates along with the rotation of the cylinder, and the spring also drives the support rod to move up and down, thereby ensuring that the rolling block is constantly contacted with the surface of the cylinder. The grounding method and the grounding device have the beneficial effects that due to the action of the spring and the rolling block in the grounding device made of a metal material, the good contact between the grounding device and the cylinder wall in rolling is ensured, and the contact point then changes along with the rolling of the cylinder, so that the grounding method is strong in generality, light in device and convenient to operate; and by utilizing the grounding method and the grounding device, the good grounding is ensured, the welding process is smooth, and the operation efficiency is improved.

Described pilot sleeve is arranged vertically, and the bottom is provided with base plate.
Described scroll box, support bar, pilot sleeve, spring and base plate are metal material and make, and guarantee ground connection.
Described support bar is square bar, and the top of pilot sleeve is provided with a square opening, and square bar passes from this hole.
A kind of cylinder ring seam welding earthing method adopts above-mentioned earthing device, and cylinder is placed on the roller support, and earthing device is placed on by the roller support, and the scroll box of earthing device contacts with drum surface, guarantees that contact is good; In the welding process, cylinder rotates at roller support, and the scroll box of earthing device rotates with rotary drum, and the spring action support bar also moves up and down thereupon, guarantees that scroll box contacts with drum surface all the time.
The support bar of described earthing device is square bar, and the top of pilot sleeve is provided with a square opening, and square bar passes from this square opening; Square opening can prevent again its rotation in the horizontal direction to the existing guide effect of square bar, thereby guarantees the good contact of moving block and cylinder.
Make one week of rotary drum before the welding, check scroll box and the cylinder Grounding of earthing device, find out that contact is good after, begin welding.
Good effect of the present invention: spring and scroll box effect in the earthing device of making by metal material, guarantee good the contacting of barrel in earthing device and the rolling, contact point changes immediately with the rolling of cylinder, and highly versatile, install light, convenient operation; The present invention can guarantee good earth, makes again welding process smooth and easy, improves operating efficiency.
