A kind of fixing device for the welding of logistics roller
Technical field
The invention belongs to logistics roller auxiliary welding equipment technical field, more particularly, to a kind of for the welding of logistics roller
Fixing device.
Background technology
Existing logistics roller divides two big class:General on power roller and unpowered roller, the wherein rotating shaft of power roller
It is provided with the gear being driven by driving, and unpowered roller is generally used for the goods conveying of light weight, the therefore group of light-type roller
By the way of the many end caps using cylinder with rotating shaft of dress are welded to each other, which has easy to assembly it is only necessary to two welding is grasped
The advantage made.
In solder technology, in welding process, especially in the welding process of melting welding and soldering, using heating metal material
To liquid, by solidifying the purpose realizing being welded to connect again, therefore direction of welding is preferably located at the lower section of staff, to keep away to matter
Harmful flowing in the metal exempting from liquid, finally affects welding effect.In existing light-type roller welding process, adopt more
End cap finally butt-welded mode will be inserted vertically into again, the metal which has liquid is past along end cap face after cylinder traverse
Dirty, cause weld deformation, thinning problem, eventually affect welding effect, reduce weld strength.
The Chinese utility model patent that patent announcement number is CN 205151033U, the day for announcing is 2016.04.13 discloses
A kind of Novel gluing welds roller, comprises cylinder and axle, also comprises one side and described cylinder friction welding, another side and described axle
The capping of friction welding, described cylinder side circularizes, and with described capping friction welding, forms fusion portion one after friction welding,
Described cover as disc, described capping is vertical with described cylinder axis, described capping also vertical with the axis of described axle
With described axle friction welding, after friction welding, form fusion portion two, the section radius of described axle are less than the section half of described capping
Footpath.
But there is a problem of in this utility model that welding is inconvenient and welding effect is poor.
