Abstract
The utility model relates to a hydraulic rapping bar of a diesel engine. The hydraulic rapping bar comprises a cylinder liner and a cylinder head arranged at one end of the cylinder liner. The hydraulic rapping bar is characterized in that a piston is arranged in an inner cavity of the cylinder liner, hydraulic oil is filled in a space between the piston and the cylinder liner, the piston is fixedly connected with one end of a pressure bar, and the other end of the pressure bar extends out of the cylinder head and is connected with a rapping bar head. An annular groove is formed in the outer surface of the piston, and a second O-shaped sealing ring is arranged in the annular groove and clings to the inner wall of the cylinder liner. A first O-shaped sealing ring is arranged between the cylinder liner and the cylinder head, and a third O-shaped sealing ring is arranged between the cylinder head and the pressure bar. A first hexagon head is arranged at the end, which is far away from the cylinder head, of the cylinder liner. The hydraulic rapping bar has the advantages that the hydraulic rapping bar is smart, reliable and reasonable in structure, phenomena of excessively high stress and uneven stress on inner rings of bearings can be effectively reduced under the buffering and balancing effects of the hydraulic oil when workers rap the bearings of power output shafts, the rapping stability can be improved, and the service lives of the bearings can be prolonged.
Description
Technical field
The utility model relates to a kind of Diesel engine power take-off lever bearing and strikes dress frock, and especially a kind of hydraulic pressure of Diesel engine strikes bar, belongs to frame for movement technical field.
Background technology
Along with the quickening of Workshop Production rhythm, it is frequent that plant personnel flows, the raising of part processing precision, and original Diesel engine power take-off lever bearing strikes the assembly quality that dress frock is difficult to guarantee part.Often produce in process of production engine power output shaft bearing and strike when dress bearing dustproof cover this phenomenon that drops, because the precision of bearing parts own is just very high, unbalance stress slightly in assembling process, the deformation quantity producing will cause dropping of bearing dustproof cover, has greatly affected productive temp and quality.Existing frock is struck bar, and the effect of power is direct, and workman's the gimmick of controlling has directly affected assembly quality, deviation slightly in assembling process, or the excessive damage that will cause bearing of exerting oneself.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of hydraulic pressure of Diesel engine to strike bar, simple in structure, easy accessibility, effectively reliable, effectively reduce workman and strike dress during power take-off lever bearing, the phenomenon of the stressed excessive and discontinuity of bearing inner race.
The technical scheme providing according to the utility model, a kind of hydraulic pressure of Diesel engine strikes bar, comprise cylinder sleeve and the cylinder head that is arranged on cylinder sleeve one end, feature is: in described cylinder sleeve inner chamber, piston is set, between piston and cylinder sleeve, be full of hydraulic oil, piston is fixedly connected with one end of depression bar, and the other end of depression bar stretches out cylinder head and connects and strike bar head in end.
Outer surface at described piston arranges cannelure, and the 2nd O RunddichtringO is set in cannelure, and the 2nd O RunddichtringO is close to the inwall of cylinder sleeve.
The one O RunddichtringO is set between described cylinder sleeve and cylinder head, the 3rd O model sealing ring is set between cylinder head and depression bar.
At described cylinder sleeve, away from one end of cylinder head, the first turret head is set.
At described depression bar, stretch out on one end of cylinder head and be provided with the second turret head.
Compared with the prior art the utility model has the following advantages: the utility model structure is ingenious, reliable, reasonable, by the cushioning balance effect of hydraulic oil, effectively reducing workman strikes while filling power take-off lever bearing, the phenomenon of the stressed excessive and discontinuity of bearing inner race, improve the stability of striking dress, extended the service life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1: the hydraulic pressure of described Diesel engine strikes bar and comprises and strike bar head 1, cylinder head 2, cylinder sleeve 3, depression bar 4, piston 5, an O RunddichtringO 6, the 2nd O RunddichtringO 7, the first turret head 8, the second turret head 9, the 3rd O model sealing ring 10 etc.
As shown in Figure 1, the utility model comprises cylinder sleeve 3 and the cylinder head 2 that is arranged on cylinder sleeve 3 one end, and the other end of cylinder sleeve 3 arranges the first turret head 8, is convenient to dismounting; In described cylinder sleeve 3 inner chambers, piston 5 is set, between piston 5 and cylinder sleeve 3, is full of hydraulic oil, piston 5 is fixedly connected with one end of depression bar 4, and the other end of depression bar 4 stretches out cylinder head 2 and connects and strike bar head 1 in end;
Outer surface at described piston 5 arranges cannelure, and the inwall that the 2nd O RunddichtringO 7, the two O RunddichtringOs 7 are close to cylinder sleeve 3 is set in cannelure, plays sealing function, prevents that the hydraulic oil in cylinder sleeve 3 from overflowing;
The one O RunddichtringO 6 is set between described cylinder sleeve 3 and cylinder head 2, the 3rd O model sealing ring 10 is set between cylinder head 2 and depression bar 4, play multi-sealed effect;
At described depression bar 4, stretch out on one end of cylinder head 2 and be provided with the second turret head 9, easy disassembly.
In the utility model, described in strike the part that the shape of bar head 1, large I strike dress as required and design separately; Described cylinder head 2 can play the effect of seal cylinder sleeve inner chamber; In the inner chamber of described cylinder sleeve 3, deposit hydraulic oil, knocking of active force born in rear end thickening; Bar head and piston are struck in each connection of two of described depression bar 4, play the effect of conductance; Hydraulic oil in the promotion compression cylinder sleeve of described piston 5 pressured bars plays the effect of buffering.
The course of work of the present utility model: knock cylinder sleeve end, the cushioning effect of percussion power by piston compression hydraulic oil is transmitted to strikes on bar head, acts on stressed bearing inner race, completes once to strike and pretends to use; Can effectively reduce workman and strike dress during bearing, the phenomenon of the stressed excessive and discontinuity of bearing inner race.
