It is vertically equipped with the screwed pipe of tubular from bull stick one end, is furnished with the threaded rod of mutual screw-thread fit, threaded rod one inside screwed pipe
Cutting ferrule of the end equipped with C-shaped tubular, the both sides of bearing are arranged with the identical L-shaped supporting rack of size, and two supporting rack ends are vertical
Equipped with the identical tabular pedestal of thickness.
As advanced optimizing for the technical program, the bull stick, supporting rack, pedestal are made of stainless steel, supporting rack
It is connect with pedestal by welding.
As advanced optimizing for the technical program, bearing is cylinder roller bearing, and bull stick passes through welding and bearing inner race
Connection, supporting rack are connect by welding with bearing outer ring.
As advanced optimizing for the technical program, the lifting pipe and screwed pipe are made of stainless steel, lifting pipe and
Screwed pipe is by being welded to connect.
As advanced optimizing for the technical program, the cutting ferrule and threaded rod are made of stainless steel, cutting ferrule and screw thread
Bar is by being welded to connect.
It is using the advantageous effect of above technical scheme：Pedestal can be lain in pipe fitting by the inner bore welding device when in use
Or the outside of inner bore of part, by bearing axis face endoporus, the then rotation and lifting pipe on bull stick adjusts screwed pipe and bearing
Distance, then the rotating threaded rod in screwed pipe, adjusts cutting ferrule at a distance from screwed pipe, welding gun is then fixed on cutting ferrule
On, welding machine is started, can rotate bull stick manually, drives lifting pipe and rotated threaded tubular, including driving threaded rod, cutting ferrule, welding gun
Rotating welding in hole, to complete inner hole welding of rapid cooling.Inner bore welding device design is simple, and of low cost, flexibility is good, can hand
It is dynamic to adjust speed of welding, and welding and assembling height can be freely adjusted, it is highly practical.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
