Abstract
The utility model discloses a grounding device for an anti-winding electric welder, which comprises an electric welder, a grounding wire, a cylinder body, a carrier roller and a grounding device, wherein the grounding device is arranged between the grounding wire and the cylinder body, and comprises a fixed conducting block, a movable conducting block and a ball bearing; the fixed conducting block is fixedly connected with the cylinder body; the ball bearing is arranged on the fixed conducting block by a shaft; the movable conducting block is sleeved and fixed on the ball bearing, and is in close contact with the fixed conducting block; and one end of the grounding wire is connected with the movable conducting block. By the grounding device, poor welding quality of welding beads caused by unstable voltage due to sparking formed by the damaged grounding wire and a contact surface is prevented; the cost is saved, and the grounding wire is prevented from being damaged; a flange and the cylinder are protected against damage, and the damage of the grounding wire due to the sparking with the contact surface is prevented; and the grounding device is safe and convenient for use.
Description
Technical field
The utility model belongs to the electric welding machine device, is specifically related to a kind of electric welding machine earthing device.
Background technology
To electric welding machine earth connection being installed is an important safety measure, the metal shell and the live part of electric welding machine insulate, can be not charged on the shell, if but the electrical equipment internal insulator is aging or damage, and electricity just may pass on the metal shell, if shell is earth-free, at this moment the people is if run into and will get an electric shock, if metal shell ground connection, electric current will flow into the earth by ground wire, the people runs into charged metal shell and just can not get an electric shock, and this line is referred to as earth connection.The general employing in prior art field is welded in earth connection on flange or the cylindrical shell steel plate, and in welding process, along with cylindrical shell rotates on carrying roller, earth connection is also along with the cylindrical shell rotation.Time has been grown earth connection and can twist into twisted shape, and can cause following shortcoming so adopt this mode to connect earth connection: 1. earth connection is damaged very soon; 2. earth connection damages back and contact-making surface sparking, causes the damage of flange or cylindrical shell steel plate easily; 3, cause voltage instability after earth connection damages the back and cylindrical shell contacts, cause the welding bead moulding poor, off quality.
Summary of the invention
In order to overcome the problems referred to above that the prior art field exists, the purpose of this utility model is, a kind of antiwind condenser discharge welder earthing device is provided, and has effectively solved earth connection winding problem in the cylindrical shell rotary course, significantly prolong the useful life of earth connection, reduced potential safety hazard.
The antiwind condenser discharge welder earthing device that the utility model provides, comprise electric welding machine, earth connection, cylindrical shell, carrying roller, it also comprises earthing device, described earthing device is arranged between earth connection and the cylindrical shell, this earthing device comprises fixedly conducting block, movable conducting block, ball bearing, fixedly conducting block is fixedlyed connected with cylindrical shell, ball bearing is arranged on fixedly on the conducting block by axle, movable conducting block suit is fixed on the ball bearing, movable conducting block closely contacts with fixing conducting block, and an end of earth connection is connected with movable conducting block.It also comprises flange, and fixedly conducting block is connected with cylindrical shell by flange.Described fixedly conducting block, movable conducting block are the copper coin cake.
The antiwind condenser discharge welder earthing device that the utility model provides, its beneficial effect are, avoid causing voltage instability to cause the welding bead poor welding quality because of earth connection damages with the contact-making surface sparking; Save cost, avoid earth connection often to damage; Protection flange and cylindrical shell are excellent, avoid striking sparks with contact-making surface because of earth connection and cause damage; Use safe and convenient.
Description of drawings
Fig. 1 is the overall structure schematic diagram of an embodiment of the utility model;

Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the antiwind condenser discharge welder earthing device to the utility model provides is described in detail.
Embodiment
With reference to Fig. 1, Fig. 2, the antiwind condenser discharge welder earthing device of present embodiment, comprise electric welding machine 1, earth connection 2, cylindrical shell 3, carrying roller 4, it also comprises earthing device, described earthing device is arranged between earth connection 2 and the cylindrical shell 3, this earthing device comprises fixed copper cake 5, active copper cake 6, ball bearing 7, flange 8, and fixed copper cake 5 is connected with cylindrical shell 3 by flange 8.Ball bearing 7 is arranged on the fixed copper cake 5 by axle, and active copper cake 6 suits are fixed on the ball bearing 7, and active copper cake 6 closely contacts with fixed copper cake 5, and an end of earth connection 2 is connected with active copper cake 6.
In welding process, when cylindrical shell 3 rotates on carrying roller 4, earthing device is also along with the friction of two copper coin cakes is rotated on cylindrical shell 3, fixed copper cake 5 on the earthing device be fixed after flange 8 is connected, active copper cake 6 rotates along with the rotation of cylindrical shell 3 under the effect of ball bearing 7, two copper coin cake phase mutual friction conductions, play the effect of carbon brush, like this, when cylindrical shell 3 rotations, earth connection 2 is non-rotary.
