Description
Technical field
The utility model relates to a kind of fixed devices of welding ground, and in particular to one kind has the anti-welding magnetic biasing of hole header end cap
Blow the fixed device of ground wire.
Background technique
The principle of welding is exactly to pass through welding equipment, workpiece, welding material to form a welding circuit, in specified position
It is solidified again after workpiece is melted simultaneously with welding material, two sseparated workpiece is securely attached to together.Therefore,
Effective, the stable connection of welding circuit has direct influence to the stabilization of welding process and welding quality.Header is as boiler
The aorta of system bears huge internal pressure in the process of running, if welding quality is unqualified, gently if lead to boiler system
System cannot effectively be run, heavy then cause serious accident.
In the past when being welded with hole header end cap and header ontology, ground wire is usually ridden over into the roll-over table that pad puts header
On, but since header has meeting play in oval and header ontology rotation process, the welding that this ground wire mode of communicating is formed
Circuit is very unstable, influences the stability of welding process and welding quality.Another way is in the center of header end cap
Ground wire, is then fixed on steel pipe, this ground wire mode of communicating can guarantee the stabilization of ground wire and header by a piece steel pipe of upper weldering
Connection, but for there is hole header end cap, since hole is located at end cap central, steel pipe can not be directly welded in end cap central position, welded
Welding arc blow can be then generated on the side in hole；Simultaneously because ground wire connection is not flexible, ground wire is easy winding, damage, consumption
Greatly.
Summary of the invention
The stability of welding circuit when in order to guarantee to have hole header end cap and header ontology is eliminated welding magnetic blow-out phenomenon, is protected
The quality and safety for demonstrate,proving header weld seam, reduce the proportion of goods damageds of welding ground, the utility model, which provides one kind, hole header end cap
The fixed device of anti-welding arc blow ground wire.
The utility model uses technical solution: one kind having the fixed device of the anti-welding arc blow ground wire of hole header end cap, including
Connecting sleeve, sealing plate, stainless steel ground wire set hanging rod, thread fixing plate, bolt；The sealing plate is circle, and the welding of sealing plate side connects
Female connector pipe, other side center weld stainless steel ground wire cover hanging rod, and the stainless steel ground wire covers in hanging rod and the connecting sleeve
Heart line is overlapped, and hanging ground-wire fixed plate is covered in the connecting sleeve, and described ground thread fixing plate lower end is equipped with bolt, is linked with by bolt
Copper wire head ground wire.
The cylinder of opening is collectively formed in the end of the connecting sleeve side in the seal plate welding.
The ground wire dead plate upper end is a semicircle being relatively large in diameter, and lower end is a lesser semicircle of diameter, upper end
The circular hole for hitching is opened, lower end sets the small sircle hole for bolt precession.
It uses principle: connecting sleeve point being welded on end cap when use, and covers the hole among end cap, welding will be installed
The ground thread fixing plate of ground wire is hitched on ground wire set hanging rod, after header is soldered, removably thread fixing plate, then by connecting sleeve and end
Spot welded joint removal between lid can be taken down.
The effect of the present apparatus is: the device both can uniformly expand welding circuit contact area, avoid welding arc blow
The generation of phenomenon；It can also guarantee that welding circuit is connected to stability by the self weight of ground thread fixing plate and ground wire, while ground wire is not
Winding, damage can occur as header rotates.

Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Fig. 1-Fig. 4 is please referred to, one kind having the fixed device of the anti-welding arc blow ground wire of hole header end cap, including connecting sleeve
(1), sealing plate (2), stainless steel ground wire set hanging rod, thread fixing plate (4), bolt (5)；The sealing plate (2) is circle, sealing plate (2)
Side is welded to connect casing (1), and other side center weld stainless steel ground wire covers hanging rod, stainless steel ground wire set hanging rod with it is described
The center line of connecting sleeve (1) is overlapped, and covers hanging ground-wire fixed plate (4) on the connecting sleeve (1), described ground thread fixing plate (4)
Lower end is equipped with bolt (5), is linked with copper wire head ground wire by bolt (5).
The sealing plate (2) is welded on the end of the connecting sleeve (1) side, and the cylinder of opening is collectively formed.
