Abstract
The invention relates to a hydraulic rapping bar for a diesel engine. The hydraulic rapping bar comprises a cylinder sleeve and a cylinder head arranged at one end of the cylinder sleeve, and is characterized in that a piston is arranged in an inner cavity of the cylinder sleeve, wherein hydraulic oil is filled between the piston and the cylinder sleeve; the piston is fixedly connected with one end of a compression bar; the other end of the compression bar extends out of the cylinder head, and the end part of the other end of the compression bar is connected with a rapping bar head; an annular groove is formed in the outer surface of the piston; a second O-shaped sealing ring is arranged in the annular groove, and clings to the inner wall of the cylinder sleeve; a first O-shaped sealing ring is arranged between the cylinder sleeve and the cylinder head; a third O-shaped sealing ring is arranged between the cylinder head and the compression bar; a first hexagon head is arranged at one end, away from the cylinder head, of the cylinder sleeve. The hydraulic rapping bar is ingenious, reliable and reasonable in structure; under the buffering and balancing action of the hydraulic oil, the phenomenon that an inner circle of a bearing is excessively and non-uniformly stressed when the bearing of a power output shaft is rapped by a worker is effectively reduced, the rapping stability is improved, and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to a kind of Diesel engine power take-off lever bearing and strike the dress frock, especially a kind of hydraulic pressure of Diesel engine strikes bar, belongs to the 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 the dress frock is difficult to guarantee part.Often produce in process of production the 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 is slightly arranged in assembling process, the deformation quantity produced 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, and deviation is slightly arranged in assembling process, or the excessive damage that will cause bearing of exerting oneself.
Summary of the invention
The objective of the invention 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, when effectively reducing the workman and striking the dress power take-off lever bearing, the phenomenon of the stressed excessive and discontinuity of bearing inner race.
According to technical scheme provided by the invention, 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, be full of hydraulic oil between piston and cylinder sleeve, piston is fixedly connected with an end of depression bar, and the other end of depression bar stretches out cylinder head and connects and strike the 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.
Away from an end of cylinder head, the first turret head is set at described cylinder sleeve.
Stretch out at described depression bar on an end of cylinder head and be provided with the second turret head.
Compared with the prior art the present invention has the following advantages: structure of the present invention is ingenious, reliable, reasonable, cushioning balance effect by hydraulic oil, effectively reducing the 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
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 present invention includes cylinder sleeve 3 and the cylinder head 2 that is arranged on cylinder sleeve 3 one ends, 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 an 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;
Stretch out at described depression bar 4 on an end of cylinder head 2 and be provided with the second turret head 9, easy disassembly.
In the present invention, the part that described shape of striking bar head 1, large I are struck dress as required designs separately; Described cylinder head 2 can play the effect of seal cylinder sleeve inner chamber; Deposit hydraulic oil in the inner chamber of described cylinder sleeve 3, knocking of active force born in the 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 invention: knock the cylinder sleeve end, the cushioning effect of percussion power by piston compression hydraulic oil is transmitted to strikes on the bar head, acts on stressed bearing inner race, completes once to strike and pretends to use; Can effectively reduce the workman and strike dress during bearing, the phenomenon of the stressed excessive and discontinuity of bearing inner race.
