The utility model relates to a grounding block for rail vehicle, the welded joint leakproofness is good, and welded intensity is high, and the mother metal part is by detachable is whole with one heat fusing formation under the circumstances of not bearing the impressed pressure during welding.
Description
Technical field
The utility model is related to a kind of earthing block for rail vehicle.Belong to field of mechanical technique.
Background technology
Earthing block overall performance need to meet DIN 43670-2 requirements, it is ensured that the good earth of equipment on vehicle, it is to avoid due to
The problems such as cable that imperfect earth is brought or device scaling loss, disabler, communication interference, bearing and mechanical part galvano-cautery.
Existing earthing block is made up of carbon steel or aluminum alloy materials, and adopts soldering, and soldering is to compare mother metal using fusing point（Quilt
Brazing material）Low-melting filling metal（Referred to as solder or solder）, less than mother metal fusing point, higher than the temperature of solder fusing point
Under, using liquid solder in mother metal moistened surface, sprawl and the joint filling in mother metal gap, be mutually dissolved and diffusion with mother metal, and
Realize the welding method of the connection between part.
The maximum problem of the earthing block of soldering is：1st, strength of joint is low, poor heat resistance, and it is tight that requirement is leveled before welding
Lattice, solder is expensive；2nd, the hole on earthing block needs to be assembled together binding post by bolt, causes when bolt is tightened
Impact of the stress to soldered fitting it is larger；And on ground wire if any electric current flow through produced by resistance heat or soldered fitting can be made
Fusing；So that joint fails.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of earthing block for rail vehicle.
What the purpose of this utility model was realized in：
A kind of earthing block for rail vehicle, is characterized in：Earthing block for rail vehicle includes workpiece one and two
Individual workpiece two, the workpiece one is " T " shape, the hole for wiring, lower end of workpiece one or so is provided with workpiece one and is respectively provided with
There is a workpiece two, workpiece one forms the chamber of a semi-closed with workpiece two, and workpiece one is brought into close contact to form weldering with workpiece two
Contact, the lower end of workpiece one is located at workpiece two side faces middle part, bottom and workpiece dimorphism grooving, the workpiece one and the work of workpiece one
Part two is made by copper clad aluminum material.
Compared with prior art, the beneficial effects of the utility model are：
A kind of earthing block for rail vehicle of the utility model, welding point good airproof performance, the intensity of welding is high, welding
When mother metal local in the case where impressed pressure is not subject to be heated fusing formed a non-removable entirety.
Description of the drawings
Fig. 1 is a kind of schematic diagram of the earthing block for rail vehicle of the utility model.
In figure：
Workpiece 1,
Workpiece 22,
Pad 3,
Groove 4,
Chamber 5.
Specific embodiment
Referring to Fig. 1, the utility model is related to a kind of earthing block for rail vehicle, including workpiece 1 and two workpiece
22, the workpiece 1 is " T " shape, the hole for wiring, lower end of workpiece 1 or so is provided with workpiece 1 and is respectively arranged with
One workpiece 22, workpiece 1 is brought into close contact to form pad 3 with workpiece 22, and the lower end of workpiece 1 is located at the side of workpiece 22
Middle part, workpiece 1 forms groove 4 with workpiece 22, and the sealing of welding can be observed at groove 4.
Wherein, workpiece 1 and workpiece 22 are made by copper clad aluminum material.
In order to ensure abundant fusion of two workpiece at pad 3, workpiece 1 be difficult with the contact surface of workpiece 22 it is excessive,
Therefore the lower end of workpiece 1 is located at the side of workpiece 22 middle part.
The workpiece 1 of T-shaped forms the chamber 5 of a semi-closed with workpiece 22, in welding process, molten bath will not sinuous flow,
The weld seam of high-quality can be obtained.
The hole opened on workpiece 1, this hole is used to connect binding post.
In referring to welding process, by welding point in the presence of high temperature etc. to molten state.
Welding method：Workpiece 1 and workpiece 22 are closely sticked together, with argon tungsten-arc welding at pad 3, heat
Amount is produced between pole rod and pad 3, in the presence of temperature field, gravity etc., is not added with pressure, two workpiece fusings it is molten
Liquid can occur mixing phenomena.After temperature is reduced, melt portions condense, two workpiece just by firm welded together, so as to complete
Into connection.
