Production line is continuous conveying articles handling machinery on certain circuit, claims again conveyor line or conveyor.According to carrying series product substantially can be divided into: this seven classes production line of belt production line, plate chain line, multiple chain line, plug-in unit line, guipure line, suspension line and cylinder production line.Generally comprise the component such as traction piece, bearing carrier, drive unit, tension device, change course device, roller and supporting member.The production line conveying capacity is large, and haul distance is long, also can finish simultaneously some technological operations in course of conveying, so use very extensive.At present, existing its wear resistance of roller for the automobile assembling production line is relatively poor, that is to say, roller easily is worn, thereby cause often changing or to keep in repair roller, shortened the working life of production line, so not only impact is produced, but also increased maintenance cost, be difficult for being applied.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of Novel hydroelectric line, comprises a plurality of roller conveyor belt, a plurality ofly disassembles worktable, back conveying stand, loopback conveying belt and be connected swash plate; Described a plurality of roller conveyor belt and a plurality of worktable interval of disassembling arrange, back conveying stand unsettled a plurality of roller conveyor belt and a plurality of disassemble worktable above, be provided with the loopback conveying belt in back conveying stand; The upper end of described connection swash plate connects back conveying stand and is connected with the output port of loopback conveying belt, and the lower end that connects swash plate is tilted to down, and its lower end mouth is unsettled above outermost roller conveyor belt.Although such scheme has improved existing production line short partial technical problems in working life to a certain extent, but, also there is following shortcoming at least in this scheme: the working life of roller is short, in addition, this roller is easy axial float in the process of work, can affect so the normal operation of production line, it is reasonable not to design.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, and long service life can prolong the production line super wear-resistant roller that is used for the automobile assembling production line in working life virtually.
For achieving the above object, the utility model has adopted following technical proposal: this is used for the super wear-resistant roller of automobile assembling production line, comprise wheel body, be provided with axis hole in the wheel body axial centre, it is characterized in that, described wheel body one end has the stop part that is connected as a single entity with wheel body, forms the circular orientation step between described stop part and the wheel body, and described wheel body surface hardness is HRC56～60.Obviously, the utlity model has that wear resistance is good, high strength, high tenacity, the advantage such as corrosion-resistant and high temperature resistant, satisfy simultaneously national relevant industries required, long service life, can also virtually prolong the working life of production line, meet the trend of current social technical development.
At the above-mentioned super wear-resistant roller that is used for the automobile assembling production line, described stop part external diameter is provided with through hole greater than the external diameter of described wheel body in the stop part axial centre, described through hole center line and axis hole central lines.
At the above-mentioned super wear-resistant roller that is used for the automobile assembling production line, described wheel body has the first annular boss away from an end of stop part, and the described body diameter of taking turns is greater than described the first annular boss external diameter.
At the above-mentioned super wear-resistant roller that is used for the automobile assembling production line, described stop part has the second annular boss away from an end of wheel body, and described stop part external diameter is greater than the external diameter of described the second annular boss.
At the above-mentioned super wear-resistant roller that is used for the automobile assembling production line, described wheel body surface roughness is Ra≤1.6.
At the above-mentioned super wear-resistant roller that is used for the automobile assembling production line, described ratio of taking turns body diameter and the external diameter of stop part is 1:1.5.
At the above-mentioned super wear-resistant roller that is used for the automobile assembling production line, described axis hole surface roughness is Ra≤1.6.In addition, the utility model adopts high-intensity metallic material to make.
Compared with prior art, this advantage that is used for the super wear-resistant roller of automobile assembling production line is: have that wear resistance is good, high strength, high tenacity, an advantage such as corrosion-resistant and high temperature resistant, satisfy simultaneously national relevant industries required, long service life, can also virtually prolong the working life of production line, meet the trend of current social technical development.
