Description
Technical field
This utility model belongs to manufacture of steel structure field of engineering technology, is specifically related to a kind of round piece circumferential weld rotating welding
Clamping device, with this unit protection earth cable wire.
Background technology
At present, the girth welding of round piece is rotational workpieces on turning rolls, is welded by submerged arc welding machine, and work
The earth lead of part directly can not be delivered to weld body by turning rolls, is easy to like that damage turning rolls equipment, it is common that welding
The output negative pole (earth lead) of equipment is directly connected with workpiece with wire.Along with the carrying out of welding, workpiece is constantly rotating, is connecing
Ground wire is also rotated into twist shape with workpiece, adds that earth lead has big electric current to pass through, and produces heat, and time length may result in
The damage of earth lead affected stream, weld defect occurred, must more renew earth lead this moment, strengthened the input ability of cost
Guarantee product quality.
Summary of the invention
This utility model purpose is to provide a kind of round piece circumferential weld rotating welding clamping device, solves round piece circumferential weld
Problem with grounding during rotating welding, the service life of extension lead, reduce production cost.
The technical solution of the utility model is: a kind of round piece circumferential weld rotating welding clamping device, including clamper, folder
One end of holder connects a screw rod, screw rod is installed successively conductive seat, fixing conductive plate, active conductive dish, spring, back-up ring and
Nut, is fixed conductive plate and is fixed with conductive seat by sunk screw, and active conductive dish contacts with fixing conductive plate by spring compression,
The lower end of active conductive dish connects earth lead, and the earth lead other end connects welding machine negative pole.
Described clamper includes conducting bracket, be connected on conducting bracket T-shaped screw mandrel and T-nut.
Described clamper includes connecting shaft, positioning sleeve and clamping nut.
This device is clamped on tube wall or circular tube end face has on the connecting hole of flange, active conductive dish by spring compression with
Fixing conductive plate contact, the lower end of active conductive dish connects ground wire, and fixing conductive plate rotates with workpiece, and active conductive dish is with solid
Determining conductive plate and produce relative motion, and the direction of grounding terminal is the most down, frictionally conduction reaches the mesh of equilibrium transmission electric current
's.
Good effect of the present utility model:
Earth lead one end is connected on active conductive dish, and the other end connects welding machine negative pole, along with the rotation of workpiece, ground connection
Wire only can move up and down and swing, and self rotates never, solve earth lead because rotating, being wound around, heating etc.
Problem, is effectively protected the service life of earth lead, reduces and again put into because of the damage of earth lead, also ensure that
Being smoothed out and product quality of welding.Active conductive dish and fixing conductive plate select the copper material conducted electricity very well, and transmit electric current
Safe and reliable.It is applicable to the welding ground connection that various round piece circumferential weld rotates.
