Description
Technical field
The utility model relates to diesel engine part maintenance technique field, particularly relates to a kind of rounding device for scene polishing boat diesel engine cylinder sleeve.
Background technology
Cylinder of diesel engine on now domestic many boats and ships is enclosed within repair procedures, all can encounter the problem that ovality appears in cylinder sleeve, occurs that ellipse is mainly because the motion of piston in cylinder sleeve causes, and comprises normal wear and inordinate wear.If its wearing and tearing also, in the limit range of using, will be taked the method for reparation certainly, because the cost of cylinder sleeve is larger, particularly external diesel engine, uses external cylinder sleeve, and price is just expensive especially.The repair method now adopting is all that cylinder sleeve is hung out from the body of diesel engine substantially, then takes workshop and repairs, and as above lathe car, upper boring machine bore holes etc., though the method for this repairing is good, need to spend many manpower and materials.Device of the present invention is exactly the wear problem that solves at the scene cylinder sleeve.The method is limited to the renovation of cylinder muff that cylinder sleeve diameter is less than 350mm, and diameter causes too greatly the deadweight of device to increase, and concerning operating personnel, labour intensity is too large.
Therefore, instantly need the urgent technical problem solving to be exactly: a kind of effective measures of proposition how can innovate, to meet the actual demand of field repair cylinder sleeve.
Utility model content
Outside the deficiency existing in the problems referred to above, the utility model provides a kind of rounding device, to solve existing repair method, takes cylinder sleeve to hang out from the body of diesel engine, then takes the problem that repair in workshop.
In order to address the above problem, the utility model provides a kind of rounding device, comprises the cross frame for supporting, and described cross frame center is provided with axle sleeve, and described axle sleeve is connected with the connecting axle of motor, and described motor is provided with handle; Described cross frame comprises four sub-stents, described in each, sub-stent is connected with overhead gage, lower baffle plate by lever arm parcel wherein, described in each, sub-stent is tightened and is connected with described lever arm by set bolt, described overhead gage is by tighting a bolt and being threaded of described support upper end, described lower baffle plate is by tighting a bolt and being threaded of described support lower end, described lever arm end is provided with bistrique and guide head, is spaced.
Preferably, described sub-stent is spill.
Preferably, between described overhead gage and lever arm, be provided with press strip.
Further, described lever arm is provided with scale.
Further, described lever arm end is provided with open slot.
Further, the emery wheel that described bistrique is semi-cylindrical form, and be provided with connection handle and be fixedly connected with by screw with the open slot of described lever arm.
Further, described guide head is identical with structure and the connected mode of described bistrique.
Preferably, described lower baffle plate is provided with scale.
Compared with prior art, the utlity model has the advantage of Solve on site renovation of cylinder muff problem, saved repair time, reduced rehabilitation cost.
Accompanying drawing explanation
Fig. 1 is side view of the present utility model;
Fig. 2 is top view of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and example, the utility model is described in further detail.But example is not as to restriction of the present utility model.
As depicted in figs. 1 and 2, embodiment of the present utility model comprises the cross frame 1 for supporting, and cross frame center is provided with axle sleeve 2, and axle sleeve is connected with the connecting axle 3 of motor 4, and motor is provided with handle 5; Cross frame comprises four sub-stents 6, each sub-stent is connected with overhead gage 11, lower baffle plate 12 by lever arm parcel wherein, each sub-stent is tightened and is connected with lever arm 8 by set bolt 7, overhead gage is by tighting a bolt and being threaded of support upper end, lower baffle plate by tight a bolt 16 with being threaded of support lower end, lever arm end is provided with bistrique 9 and guide head 10, is spaced.
Sub-stent is spill.
Between overhead gage and lever arm, be provided with press strip 13.
Lever arm is provided with scale.
Lever arm end is provided with open slot.
Bistrique is the emery wheel of semi-cylindrical form, and is provided with connection handle 15 and is fixedly connected with by screw 14 with the open slot of lever arm.
Guide head is identical with structure and the connected mode of bistrique.
Lower baffle plate is provided with scale.
The course of work of the present embodiment and principle: rounding device is put into cylinder sleeve inside, the diameter of supposing cylinder sleeve is 300mm, now be deformed into an ellipse, oval major axis is 300+0.6mm, its minor axis is 300+0.3mm, regulate the lever arm above cross frame, the fixing set bolt of lever arm is come loose, mobile lever arm, by the scale on lever arm and the scale on lower baffle plate, principle is the same with the principle of slide measure, the distance of bistrique and bistrique and the distance of guide head and guide head are guaranteed at 300+0.32mm, bistrique is the emery wheel of semi-cylindrical form, the shape of guide head is the same with bistrique, material is wear-resisting alloy material, guide head plays the effect of guiding and balance.Now, open switch, allow the electric machine rotation, the speed of rotation be 80r/min, staff's both hands are held the position of handle, allow bistrique do relative motion with the endoporus of cylinder sleeve at leisure, the process of both having polished allows rounding device move up and down simultaneously, guarantees the consistent size up and down of cylinder sleeve bore, the general depth of cut is each 0.02mm, until the ovality of cylinder sleeve is eliminated.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
