During welding operation, the welding part is arranged on the utility model, so that the high temperature generated by welding is transmitted to the metal heat dissipation sleeve through the insulating ceramic plate in time, and the local deformation caused by the high temperature generated by welding is avoided; the insulating ceramic piece is arranged on the metal heat dissipation sleeve, so that the problem that electric arcs cannot be concentrated is solved.
Description
Technical Field
The utility model relates to a head is accepted in switch board wire side welding operation.
Background
A back plate of the power distribution cabinet is provided with holes with certain specifications due to the requirements of ventilation and heat dissipation, and the holes are covered with a net surface for intercepting foreign matters; the mesh surface is usually connected to the back plate by adopting an argon arc welding technology, and because the thickness of the back plate is usually only one millimeter to two millimeters and the thickness of the mesh surface is very thin, in the welding process, the back plate and the mesh surface are easy to deform due to high temperature, so that waste products are generated.
Disclosure of Invention
The utility model aims to solve the above problem, a head is accepted in switch board wire side welding operation is provided, specifically realizes by following technical scheme:
a net surface welding operation bearing head of a power distribution cabinet comprises an end rod arranged below a welding gun, an insulating ceramic piece and a metal heat dissipation sleeve; the end rod is fixedly arranged below a tungsten electrode of the welding gun and is electrically connected with a ground wire of the welding gun; the metal heat dissipation sleeve is sleeved on the end rod, the insulating ceramic sheet covers the upper side face of the metal heat dissipation sleeve, and the insulating ceramic sheet is flush with the upper end of the end rod.
The power distribution cabinet mesh surface welding operation bearing head is further designed in that the diameter of the lower portion of the end rod is larger than that of the upper portion of the end rod, so that a first limiting step surface is formed in the middle of the end rod, a through hole for the end rod to penetrate through is formed in the middle of the metal heat dissipation sleeve, and a second limiting step surface matched with the limiting step surface is formed in the through hole.
The utility model provides a switch board net face welding operation accept head, its further design lie in, the cross section of the lower part of end pole personally submits many deformations, the lower part of through-hole is the polygon that suits with the end pole lower part, thereby metal heat dissipation cover can not produce the rotation for the end pole.
The power distribution cabinet mesh surface welding operation bearing head is further designed in that a cooling hole channel is formed in the metal heat dissipation sleeve and is connected with an external cooling water source.
The beneficial effects of the utility model reside in that:
during welding operation, the welding part is arranged on the utility model, so that the high temperature generated by welding is transmitted to the metal heat dissipation sleeve through the insulating ceramic plate in time, and the local deformation caused by the high temperature generated by welding is avoided; the insulating ceramic piece is arranged on the metal heat dissipation sleeve, so that the problem that electric arcs cannot be concentrated is solved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the net surface welding operation bearing head of the power distribution cabinet shown in fig. 1 comprises an end rod 1 arranged below a welding gun, an insulating ceramic piece 2 and a metal heat dissipation sleeve 3; the end rod is fixedly arranged below a tungsten electrode of the welding gun and is electrically connected with a ground wire of the welding gun; the metal heat dissipation sleeve is sleeved on the end rod, the insulating ceramic sheet covers the upper side face of the metal heat dissipation sleeve, and the insulating ceramic sheet is flush with the upper end of the end rod.
During welding operation, the welding part is arranged on the utility model, so that the high temperature generated by welding is transmitted to the metal heat dissipation sleeve through the insulating ceramic plate in time, and the local deformation caused by the high temperature generated by welding is avoided; the insulating ceramic piece is arranged on the metal heat dissipation sleeve, so that the problem that electric arcs cannot be concentrated is solved.
The diameter of the lower part of the end rod is larger than that of the upper part of the end rod, so that a first limiting step surface is formed in the middle of the end rod, a through hole for the end rod to pass through is formed in the middle of the metal heat dissipation sleeve, and a second limiting step surface matched with the limiting step surface is formed in the through hole. Based on this, the metal heat dissipation cover can directly cup joint on the end pole, and does not need other parts to fix.
The cross section of the lower part of the end rod is deformed, the lower part of the through hole is a polygon matched with the lower part of the end rod, in the embodiment, the lower part of the through hole is a regular hexagon, and therefore the metal heat dissipation sleeve cannot rotate relative to the end rod.
The metal heat sink sleeve has a cooling channel 31 inside, which is connected to an external cooling water source via a hose. The cooling water source flows through the inner part of the metal radiating sleeve and takes away heat transferred to the metal radiating sleeve in the welding process.
