Description
Technical field
The utility model belongs to mechanical equipment technical field, particularly relates to a kind of roll shaft structure being convenient to manufacture.
Background technology
Roller-way is requisite equipment in modern Rolling production, roll shaft is comparatively huge as its quantity of chief component of roller-way, current roll shaft mostly is Welding Structure, its part---spindle nose class part all adopts cast steel material because of roller structure reason, its blank production cycle is long, costly, and also needs before welding to process to obtain locating surface to cast steel parts subregion, turn increase cost like this, reduce the production efficiency of roll shaft.
Summary of the invention
The utility model provides a kind of roll shaft structure being convenient to manufacture, to solve the problem that cost is high, the process-cycle is long in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of roll shaft structure being convenient to manufacture, it is characterized in that: comprise roll shaft, described roll shaft comprises roll shaft spindle nose A, rod body, roll shaft spindle nose B, described roll shaft spindle nose A, roll shaft spindle nose B is arranged at the both sides of rod body respectively, the two ends of described rod body are intilted inclined plane, described roll shaft spindle nose A, the junction of roll shaft spindle nose B and rod body is plane, weld part A is provided with between described roll shaft spindle nose A and rod body, weld part B is provided with between described roll shaft spindle nose B and rod body, described weld part A, weld part B is ring-type, described roll shaft spindle nose B is provided with flat key A, flat key B, described roll shaft is positioned at above gripper shoe, described gripper shoe is fixed with roll shaft seat A, roll shaft seat B, one end of described roll shaft is positioned at roll shaft seat A, the other end passes roll shaft seat B and is connected with decelerator, motor, described decelerator is between described roll shaft seat B and motor, spring fastening A is provided with below described gripper shoe, spring fastening B, described spring fastening A comprises overhead gage, lower shoe, described lower shoe is provided with limited post, cylindrical spring is provided with between described overhead gage and lower shoe, described cylindrical spring is enclosed within the outside of described limited post, connecting rod is provided with between described overhead gage and gripper shoe, the structure of described spring fastening B is identical with the structure of spring fastening A.
The material of described roll shaft spindle nose A, roll shaft spindle nose B is hot rolled rod.
Described spring fastening A, spring fastening B positional symmetry.
Described flat key A, flat key B are positioned at the side of roll shaft spindle nose B, and are symmetrical arranged.
The beneficial effects of the utility model are:
The junction of roll shaft spindle nose and rod body is arranged on the inside of rod body by 1 the technical program, due to the maximum gauge of roll shaft spindle nose and minimum diameter difference little, just hot rolled rod can be adopted as raw material, location dimension that can be corresponding with rod body according to the appearance and size processing of hot rolled rod before welding, due to hot rolled rod blank shape and surface accuracy is higher can not carry out welding before processing directly its outer surface is used as locating surface, so just, decrease one manufacturing procedure, improve the production efficiency of roller.
2 are provided with spring fastening below gripper shoe, can play the effect of damping during roll shaft work.
3 weld parts are ring-type, can reinforce the structure of roll shaft.
