Abstract
The utility model relates to a grounding device for rotary welding, which is characterized in that the grounding device comprises a clamp body, the clamp body is provided with a C-shaped opening, and the upper part of the C-shaped opening is provided with a penetrated screw hole which is vertically downward; a lock screw is arranged in the screw hole and can move in a rotation way up and down; and the side of the clamp body, which is not provided with an opening, is provided with a shaft fixed with the clamp body, the axis of the shaft is parallel to a rotary axis of a cylinder structure during welding, a ground wire connector capable of rotating along the shaft is arranged on the shaft, and one end of a ground wire is fixedly connected with the ground wire connector. The utility model has the characteristics that the grounding device has excellent contact and can effectively prevent the ground wire from twisting and knotting.
Description
Technical field
The utility model belongs to the welding processing technical field, is specifically related to a kind of rotating welding grounding device of cylinder type spare.
Background technology
Cylinder type spares such as pipeline, cylindrical shell, ship jar, boiler are after the pre-assembly unit of more piece on the turning rolls, under go on foot operation and just use automatic submerged-arc welding machine and directly over cylindrical shell, weld, in the time of Lincoln weld, turning rolls can rotate by the speed of technological requirement, thereby the formation circular weld splices the cylindrical shell of two brachymemmas the cylindrical shell of growth.
During cylindrical shell welding at present, welding ground is often pushed down with briquetting, and is welded on the drum surface, and the back that finishes to be welded is with under the gas welding.Perhaps directly ride over surface of the work with steel bar.Above-mentioned two kinds of ground wire bridging methods not only can cause surface of the work that crator, cutting scar are arranged, and also can loose contact cause the contact-making surface sparking, the damage surface of the work.Bigger disadvantage is cylindrical shell when welding is rotated, and ground wire also can and then rotate, and after rotating cycle was many, welding ground just can twist, tie a knot, and the lighter damages welding ground, damages the welding machine binding post; Weight person causes short circuit, causes ground wire to be scrapped, electric arc potential safety hazard such as hurt sb.'s feelings.
Summary of the invention
The purpose of this utility model is to provide a kind of good, as to prevent ground wire distortion knotting rotating welding grounding device that contacts.
To achieve these goals, the technical solution of the utility model is: the rotating welding grounding device is characterized in that: it comprises that a jig main body, this jig main body are provided with " ㄈ " shape opening, and the top of " ㄈ " shape opening is provided with perforation screw vertically downward; One tie down screw is located in this screw and turn up and down; The not open side of jig main body is provided with fixing with it axle, and the rotation when axis welds with cylindrical structure spare is parallel, and axle is provided with can be around the ground of its rotation wire-connecting device, and ground wire one end is fixedly connected on the ground wire-connecting device.
Described ground wire-connecting device is connected with bearing with axle.
Described ground wire-connecting device is provided with screw, and brass bolt passes screw is pushed down ground wire through the copper lug pressure head line nose.
The beneficial effects of the utility model are:
1. contact is good.
2. prevent ground wire distortion, knotting.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-jig main body, 2-" ㄈ " shape opening, 3-tie down screw, 4-axle, 5-ground wire-connecting device.
Embodiment
As shown in Figure 1, the rotating welding grounding device, it comprises that a jig main body 1, this jig main body 1 are provided with " ㄈ " shape opening 2, the top of " ㄈ " shape opening 2 is provided with perforation screw vertically downward; One tie down screw 3 is located in this screw and turn up and down; Cylindrical structure spare places " ㄈ " shape opening 2, turn tie down screw 3 can clamp cylindrical structure spare, the not open side of jig main body 1 is provided with fixing with it axle 4, and the rotation the when axis of axle 4 welds with cylindrical structure spare is parallel, and axle 4 is provided with around the ground of its rotation wire-connecting device 5.
In order can better to rotate, be connected with bearing between ground wire-connecting device 5 and the axle 4.Ground wire-connecting device 5 is provided with screw, is pressed on this screw with copper lug pressure head and the brass bolt line nose with ground wire.
During welding, jig main body 1 is with columnar structured rotation, and ground wire-connecting device 5 is around axle 4 opposite spins of jig main body 1, and the old place line can not twine, tie a knot.
