Abstract
The invention relates to a main roller supporting structure of a straightening machine. The main roller supporting structure comprises a main roller and a main shaft, the main roller is fixedly arranged on the main shaft through a flat key, the two ends of the main shaft are rotatably borne and arranged on bearing pedestals on the two sides of the main roller through supporting bearing assemblies respectively, and the bearing pedestals are fixedly arranged on a bearing base. The main roller supporting structure is characterized in that each supporting bearing assembly comprises a centering roller bearing and a bearing sleeve, the ends of the main shaft are arranged in the centering roller bearings, the centering roller bearings are arranged in the bearing sleeves, and the bearing sleeves are located in the bearing pedestals. The main roller supporting structure is simple and reasonable in design, the main roller can roll more stably, and the straightening precision of the straightening machine can be improved.
Description
Technical field
The present invention relates to arbor press main roller wheel supporting construction, belong to steel construction processing and manufacturing technical field.
Background technology
Along with the fast development of China's steel construction industry, the H profile steel for steel-structure factory building develops to meticulous type and heavy duty detergent day by day, and the group how improving H profile steel founds precision, working (machining) efficiency and automaticity, has become the difficult problem that steel construction industry must overcome.
H profile steel is by two blocks of wing plates and assembled group of one block of web is vertical forms, and the relative position relation of web and wing plate directly has influence on the qualification rate of H profile steel finished product.Existing general group to found machine be all by carrying out the setting of artificial position to the assembly welding of H profile steel needed in advance, and then carry out H-shaped steel assembly welding, adopt the position that the H profile steel of processing in this way is difficult to locate exactly each plate, always there will be some deviations, this just needs to use follow-up rectification step.But the structural design that current arbor press has is too complicated, is not suitable for production requirement, and the low problem of precision is corrected in the too simple existence of structure, and particularly as the main roller wheel of arbor press pith, its traveling comfort has material impact to rectification precision.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of arbor press main roller wheel supporting construction, its structure is simple, reasonable in design, the rolling of main roller wheel can be made more steady, be conducive to the rectification precision improving arbor press.
According to technical scheme provided by the invention: arbor press main roller wheel supporting construction, comprise main roller wheel and main shaft, main roller wheel is fixedly mounted on main shaft by flat key, main shaft two ends are arranged on the bearing block of main roller wheel both sides respectively by support bearing assembly rotatably support, and bearing block is fixedly mounted on bearing base; It is characterized in that: described support bearing assembly comprises self-aligning roller bearing and bearing holder (housing, cover), described spindle nose is contained in self-aligning roller bearing, and self-aligning roller bearing is contained in bearing holder (housing, cover), and bearing holder (housing, cover) is positioned in bearing block.
As a further improvement on the present invention, the bearing block of described main roller wheel side is fitted with bearing stifle, in self-aligning roller bearing, bearing holder (housing, cover) and main shaft end are encapsulated in by bearing stifle; The bearing block of described main roller wheel opposite side is fitted with the logical lid of bearing, in self-aligning roller bearing and bearing holder (housing, cover) are encapsulated in by the logical lid of bearing, the centre bore that main shaft leads to lid from bearing stretches out as axle stretch end.
compared with prior art, tool has the following advantages in the present invention:structure of the present invention is simple, reasonable in design, the rolling of main roller wheel can be made more steady, be conducive to the rectification precision improving arbor press.
Accompanying drawing explanation
Fig. 1 is the structural front view of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the arbor press main roller wheel supporting construction in embodiment leads to the compositions such as lid 6, main shaft 7 and bearing base 8 primarily of bearing stifle 1, bearing block 2, self-aligning roller bearing 3, main roller wheel 4, bearing holder (housing, cover) 5, bearing.
As shown in Figure 1, described main roller wheel 4 is fixedly mounted on main shaft 7 by flat key, and main shaft 7 two ends are arranged on the bearing block 2 of main roller wheel 4 both sides respectively by support bearing assembly rotatably support, and bearing block 2 is fixedly mounted on bearing base 8; Described support bearing assembly forms primarily of self-aligning roller bearing 3 and bearing holder (housing, cover) 5, and described main shaft 7 end is contained in self-aligning roller bearing 3, and self-aligning roller bearing 3 is contained in bearing holder (housing, cover) 5, and bearing holder (housing, cover) 5 is positioned in bearing block 2.The bearing block 2 of described main roller wheel 4 side is fitted with bearing stifle 1, in self-aligning roller bearing 3, bearing holder (housing, cover) 5 and main shaft 7 end are encapsulated in by bearing stifle 1; The bearing block 2 of described main roller wheel 4 opposite side is fitted with bearing and leads to lid 6, bearing leads in self-aligning roller bearing 3 and bearing holder (housing, cover) 5 be encapsulated in by lid 6, and the centre bore that main shaft 7 leads to lid 6 from bearing stretches out as axle stretch end.
During embody rule, the axle stretch end of main shaft 7 connects motor reducer, drives main shaft 7 and main roller wheel 4 to rotate, carry out corrective operations when motor reducer starts.
