Abstract
The utility model discloses a kind of dual checknut linking sinking rollers, including roller, roll shaft, two connecting bushings；Connecting bushing ring flange excircle is equipped with external screw thread, and roller both ends seam allowance hole is internal thread hole, and connecting bushing ring flange excircle external screw thread is that internal thread hole is connect with roller both ends seam allowance hole；Roll shaft is the monolithic construction for axially penetrating through two connecting bushing inner holes, is fixedly connected with connecting bushing；Roller end seam allowance hole, connecting bushing ring flange excircle junction are equipped with 1 or more the alignment pin I for extending radially through roller end seam allowance hole hole wall insertion connecting bushing ring flange；Connecting bushing, roll shaft connecting portion are equipped with 1 alignment pin II, and alignment pin II is radial to run through roll shaft from connecting bushing small end.The utility model structural strength, rigidity are high, in use process, loosen when can effectively prevent roller, connecting bushing and connecting bushing, roll shaft use, and roller, connecting bushing are assembled or dismantled high-efficient.
Description
Technical field
The utility model relates to Hot Galvanizing Technology field, sinking roller on especially a kind of hot zinc plating equipment.
Background technique
Sinking roller on existing hot zinc plating equipment generally comprises roller, two roll shafts, two connecting bushings, and connecting bushing is
Stepped construction, big end are ring flange, and roller both ends seam allowance hole is sleeved on connecting bushing ring flange, and is fixedly connected；Connection
Axle sleeve small end is sleeved on roll shaft one end, and is fixedly connected；The major defect of this sinking roller is: first is that structural strength, rigidity
Difference；Second is that roller, connecting bushing are assembled or are dismantled time-consuming bothersome；Third is that roller, connecting bushing and connecting bushing, roll shaft junction
It is easy to loosen in use, influences the normal use of sinking roller.
Summary of the invention
Structural strength, rigidity can be significantly improved in view of the shortcomings of the prior art, the utility model provides a kind of, can significantly be mentioned
Efficiency is dismantled in high roller, connecting bushing assembling, pine when can effectively prevent roller, connecting bushing and connecting bushing, roll shaft use
Dynamic dual checknut linking sinking roller.
The utility model is achieved through the following technical solutions technical goal.
Dual checknut linking sinking roller, including roller, roll shaft, two connecting bushings；The connecting bushing is rank
Ladder type structure, big end are ring flange；The seam allowance hole at the roller both ends is sleeved on connecting bushing ring flange, and is fixedly connected；
It is theed improvement is that: the connecting bushing ring flange excircle is equipped with external screw thread, and the roller both ends seam allowance hole is internal screw thread
Hole, the connecting bushing ring flange excircle external screw thread are that internal thread hole is connect with roller both ends seam allowance hole；The roll shaft is axis
To the monolithic construction for running through two connecting bushing inner holes, it is fixedly connected with two connecting bushings；The roller end seam allowance hole,
Connecting bushing ring flange excircle junction is equipped with 1 or more and extends radially through roller end seam allowance hole hole wall insertion connecting bushing method
The alignment pin I of blue disk；The connecting bushing, roll shaft connecting portion are equipped with 1 alignment pin II；The alignment pin II is radial
Run through roll shaft from connecting bushing small end.
In above structure, the alignment pin I is evenly arranged on roller end seam allowance hole, the connection of connecting bushing ring flange excircle
Locate on circumference.
The utility model compared with prior art, has the positive effect that:
1, roll shaft is the monolithic construction for axially penetrating through two connecting bushing inner holes, significantly improve the utility model intensity and
Rigidity.
2, connecting bushing is threadedly coupled with roller, is significantly improved roller, connecting bushing assembling or is dismantled efficiency.
3, roller end seam allowance hole, connecting bushing ring flange excircle junction are equipped with 1 or more and extend radially through roller end
Portion's seam allowance hole hole wall is inserted into the alignment pin I of connecting bushing ring flange, can prevent roller, connecting bushing from generating when using opposite
Rotation；Connecting bushing, roll shaft connecting portion are equipped with 1 alignment pin II, and alignment pin II is radial to be run through from connecting bushing small end
Roll shaft can prevent connecting bushing, roll shaft from generating axial float, and locking measures play dual anti-loose effect at two.
4, alignment pin I is evenly arranged on roller end seam allowance hole, on the circumference of connecting bushing ring flange excircle junction, so that
Roller, connecting bushing junction structural strength are uniform.
Detailed description of the invention

Axle sleeve 3 is stepped construction, and big end is ring flange；The seam allowance hole at 1 both ends of roller is sleeved on 3 ring flange of connecting bushing, and solid
Fixed connection；3 ring flange excircle of connecting bushing is equipped with external screw thread, and roller both ends seam allowance hole is internal thread hole, 3 flange of connecting bushing
Disk excircle external screw thread is that internal thread hole is connect with roller both ends seam allowance hole；Roll shaft 2 is to axially penetrate through two 3 inner holes of connecting bushing
Monolithic construction, be fixedly connected with two connecting bushings；1 end seam allowance hole of roller, the connection of 3 ring flange excircle of connecting bushing
Place is equipped with 1 or more (the present embodiment is 6) and extends radially through 1 end seam allowance hole hole wall of roller insertion 3 ring flange of connecting bushing
Alignment pin I 4, in the present embodiment, alignment pin I 4 is evenly arranged on 1 end seam allowance hole of roller, 3 ring flange excircle of connecting bushing connects
It connects on place's circumference；Connecting bushing 3,2 connecting portion of roll shaft are equipped with 1 alignment pin II 5；Alignment pin II 5 is radial from connecting shaft
3 small ends are covered through roll shaft 2.
