Abstract
The utility model relates to a rotary earthing device. A conductive copper shaft penetrates into the middle of an open holder, the copper shaft and the open holder are fixed via a pressure plate and locking screws, a rotary connection seat is arranged on the copper shaft, a hole is arranged in the middle of the connection seat, a cable core is pressed by an inner pressure plate through fastening screws, a chrome molybdenum copper gasket is mounted on an upper workpiece contact portion of the open holder, and an adjusting bolt is mounted on the lower portion of the open holder. The rotary earthing device is compact in structure and reasonable in design, earthing wires cannot be rotated to generate twisting force along with the workpiece during rotary welding of the workpieces, welding interruption due to cable twisting force is avoided, so that welding is continued, welding quality is ensured and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of cylindrical shape work and carries out circumferential weld weldering, especially relates to a kind of cylindrical workpiece carrying out circumferential weld when rotating welding continuously, twists strength youngster's conductive mechanism for avoiding the earth cable spiral.
Background technology
At present, connecing at the circular seam welding of cylindrical vessel mainly is to utilize turning rolls to drive the workpiece rotation, and welding gun keeps motionless the welding at the peak of workpiece.Along with increasing of thick-walled vessel, bevel for welding is darker, even welding process may be carried out several times, tens times tens times, thereby the ground wire that is connected with workpiece will produce stubborn strength youngster phenomenon along with the rotation of workpiece, because the stubborn strength youngster of ground wire often makes welding interrupt, and influences welding quality and welding efficiency.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, and welding ground is not twisted the rotation grounding device of strength in the rotating welding process.
In order to achieve the above object, the technical solution adopted in the utility model is: the copper axle that penetrates a conduction at opening deck middle part, copper axle and opening deck are fixed by pressing plate and lock-screw, the copper axle is provided with the single-revolution junction block, the junction block middle part is provided with a hole, cable core is compressed cable core by clip plate by holding screw, in the upper workpiece contact portion of opening deck the chrome molybdenum copper packing is housed, and the adjustment bolt is equipped with in the bottom of opening deck.
The utility model has the advantages that:
Compact conformation, reasonable in design, realized that earth connection in the workpiece rotating welding process can be not produce with the rotation of workpiece and twisted strength youngster phenomenon, can welding interrupted, thereby welding is carried out continuously, not only guarantee welding quality, also improved production efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model penetrates the copper axle 1 of a conduction at opening deck 4 middle parts, copper axle 1 is fixing by pressing plate and lock-screw 3 with opening deck 4, copper axle 1 is provided with single-revolution junction block 2, junction block 2 middle parts are provided with a hole, cable core is compressed cable core by clip plate 8 by holding screw 7, in the upper workpiece contact portion of opening deck 4 chrome molybdenum copper packing 5 is housed, and the bottom of opening deck 4 is equipped with and is adjusted bolt 6.
The utility model penetrates the copper axle 1 of a conduction at opening deck 4 middle parts, copper axle 1 is fixing by pressing plate and lock-screw 3 with opening deck 4; Establish single-revolution junction block 2 on the copper axle 1, junction block middle part is provided with a hole as inserting earth connection cable core hole, and cable core is compressed cable core by clip plate 8 by holding screw 7; Top and workpiece contact portion at opening deck 4 increase chrome molybdenum copper packing 5, strengthen conductivity and resistance to wear; The bottom of opening deck 4 is clamped on the opening deck on the workpiece by adjusting bolt for adjusting bolt 6; The rotation grounding device charges into conductive paste between copper axle 1 and revolution junction block 2, promptly lubricate strengthens electric conductivity again.The utility model is resultful have been realized that earth connection in the workpiece rotating welding process can be not produce with the rotation of workpiece and has twisted strength youngster phenomenon, can welding be interrupted, thereby welding is carried out continuously, and not only guaranteed welding quality, also improved production efficiency.
