Description
Technical field
The present invention relates to a kind of roller, more particularly, to a kind of roller of printing machine.
Background technology
Roller includes roll body, and roll body includes version cylinder 1 and plug 2, traditional version cylinder 1 and the cooked mode of plug 2
It is that a platform is drawn out with lathe in the internal diameter of version cylinder 1, version tin 1 is put into after then plug 2 is heat-treated
The inside, is commonly called as " heat is embraced ", as shown in Figure 3.This cooked mode efficiency comparison is low, and expense is huge, because
For version cylinder more than 6mm seamless steel pipe must be used just to process.If using 4mm steel pipe, plug
Be loaded into, in cylindrical lathe process will because tube wall is thin and caused by car leak, produce waste product, once car leak once must
It must start anew to re-work.So in cost, causing huge waste in terms of the cycle.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of roller.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of roller, including roll body, and the central shaft being connected with roll body, described roll body include version cylinder and symmetrical
The plug at version cylinder two ends is fixed on, described central shaft passes through two plugs and is secured to connection, described plug bag
The end face for matching contact version cylinder and the limiting section welded with version cylinder end face are included, and inserts the grafting of the endoporus of version cylinder
Portion, described limiting section is integrally formed around plug division, on limiting section around plug central point be evenly distributed with to
Few two spacing preiections, the end face of described version cylinder is provided with the groove of matching spacing preiection.By spacing preiection plus
The mode of matching grooves, can increase the fixed effect of plug and version cylinder, particularly effectively both can be prevented relative
Rotate, while enabling to restraining force more to balance around the equally distributed mode of plug central point, so as to be hardly damaged portion
Part.
Described plug division includes integrally formed two parts：A part is fixedly connected with limiting section, and another part is convex
Go out limiting section and form insertion version cylinder and the frustum being in close contact with version cylinder internal face.The setting of frustum facilitates grafting
Insertion is docked with version cylinder in portion.
Described limiting section is matches the circular ring structure of version cylinder end face, and the circular ring structure internal face is connected simultaneously with plug division
It is integrally formed.
Described plug is provided with the through hole passed through for central shaft in center, and spline is provided with through hole, described
Central shaft is provided with moves radially portion with the anti-of spline mating connection, is also fixedly mounted props up anti-footpath on center shaft
To the anti-axial movement portion of move portion.The anti-of the connecting portion of central shaft and plug moves radially portion and anti-axial movement
The setting in portion, can prevent between central shaft and plug to axial with radial displacement so that ensure that central shaft,
Stablize between plug and version cylinder three in high-speed cruising, do not vibrate.
Place is threaded the disk in hole centered on described anti-axial movement portion, and the disk is by screwed hole in central shaft
It is upper to be fixedly mounted, and prop up and anti-move radially portion.Anti- axial movement is used as using the disk being connected with central axle threads
Portion, constant situation generation is changed in maintenance when being completely fixed locked this avoid anti-axial movement portion and central shaft.
The outer edge part of described disk is also welded and fixed with plug.Marginal portion is fixed by the way of welding,
Disk and central shaft were so both strengthened and had only had and be screwed and cause fixed illusive problem, in parts such as disks
Need repairing replacing when, and only need add to disc circumference except weldering can be achieved to be convenient for changing.
Seal washer is additionally provided between portion in disk and anti-move radially.Seal washer effectively avoids version cylinder work
When, ink on roll surface etc. enters the connecting portion of version cylinder along plug, so as to cause corrosive wear etc..
The end face of described limiting section and version cylinder is welded and fixed by weld part, and thickness is also coated with weld part outer surface
0.08~0.12mm layers of copper.Layers of copper can be effectively protected weld part and be damaged from external corrosion, so as to influence
Limiting section is fixedly connected with effect with version cylinder.
Compared with prior art, the present invention has advantages below：
(1) it is fixedly connected between plug and version cylinder using the stifled mode of lid, while the grafting with frustum on plug
The setting in portion, can easily realize being fixedly connected for plug and version cylinder, thus alleviate the labor intensity of workman,
Improve production efficiency.In addition, this be fixedly connected with form, the diametric requirements to version cylinder are also greatly reduced, are had
What is imitated reduces cost.
(2) spacing fixation is distinguished in pass through anti-axial movement portion and the anti-portion of moving radially of plug and central shaft, it is ensured that
Fixed effect between the two, and then avoid roller in high speed rotating operation, because the connection of each part is not firm
The generation of the problems such as vibration caused.
(3) seal washer and the isostructural setting of layers of copper further avoid the phenomenons such as the corrosion of coupling part
Occur, and then enhance the stability and service life of whole roller structure.
