Abstract
The utility model discloses a dismounting device of an air cylinder cover seat ring. An end of a coordination part of the seat ring is a coordination part which is in a cone platform shape, and a circle of protrusions is placed at the end of the coordination part along the peripheral direction. A through hole is formed in a connection part of the seat ring, the connection part of the seat ring is divided into four equal elastic bodies along the length direction of the connection part, and the seat ring is further provided with a positioning rod with the external diameter larger than that of the through hole. The positioning rod is inserted into the through hole and is matched with a thread hole formed in a connection part of the positioning rod. When the dismounting device of the air cylinder cover seat ring is used, the connection part of the seat ring penetrates through the seat ring, the positioning rod is used for enabling the elastic bodies to expand outwards to enable the coordination part which is in the cone platform shape to be tightly matched with the inner wall of the seat ring, and the protrusions at the end of the coordination part are used for clamping the end of the seat ring. The back end face of the positioning rod is hammered by applying of a hammer, and pressure force produced by the hammer is evenly centralized on the end face of the seat ring and the seat ring hole. Meanwhile, the situation that an air cylinder cover cannot be damaged in the process of dismounting the seat ring can be guaranteed due to the elasticity of the elastic bodies, so that the seat ring is dismounted.
Description
Technical field
The utility model relates to a kind of demounting tool, more precisely, relates to a kind of provision for disengagement of cylinder cover seat ring.
Background technology
In the design of middle-size and small-size engine, making, under the underproof situation of engine cylinder cap seat ring, press-fiting cylinder cap seat ring later needs to remove, change, otherwise whole cylinder cap will be scrapped, and the present effective means of not disassembling seat ring, cylinder head needs to change again processing, causes cost waste.
Summary of the invention
The utility model provides a kind of provision for disengagement of cylinder cover seat ring in order to solve problems of the prior art, and it is simple in structure, can effectively underproof seat ring be disassembled from cylinder cover, easy to use, and reduced the scrappage of cylinder cover, seat ring, reduced production cost.
In order to realize above-mentioned purpose, the technical solution of the utility model is: a kind of provision for disengagement of cylinder cover seat ring, the backstay connecting portion and the seat ring connecting portion that comprise coaxial connection, the termination of described seat ring auxiliary section is one to be the auxiliary section of circular cone shape, described termination in the auxiliary section is provided with a circle projection along its circumferencial direction, described seat ring connecting portion is provided with through hole, described seat ring connecting portion is along the elastomer that is cut into quarter on its length direction, and the gap between the described adjacent resilient body connects to described through hole; Also be provided with external diameter greater than the backstay of described through hole, described backstay inserts in the through hole, and and the screwed hole that arranges of backstay connecting portion cooperate.
Preferably, the nominal diameter of described screwed hole is less than the diameter of through hole.
Preferably, the gap between the described adjacent resilient body is less than the diameter of seat ring auxiliary section through hole.
Provision for disengagement of the present utility model is when disassembling the seat ring of cylinder cover, the seat ring connecting portion passes seat ring, make the inwall matched in clearance of seat ring auxiliary section and seat ring, backstay passes the guide hole of valve, and penetrate the through hole of seat ring auxiliary section, screw in the screwed hole of seat ring connecting portion, form screw thread pair, the diameter of backstay is greater than the diameter of through hole, thereby make elastomer expand, in order to the auxiliary section that is circular cone shape and the inwall of seat ring are cooperated more closely, simultaneously, the projection of termination, auxiliary section is blocked the termination of seat ring.At this moment, adopt the rear end face of hand hammer hammering backstay, the pressure that hand hammer produces evenly concentrates on the end face and seat ring hole of seat ring, simultaneously, because therefore the elasticity of elastomer self can guarantee that seat ring can not damage cylinder head, thereby seat ring is removed in the process of disassembling.
Description of drawings
Fig. 1 shows the part-structure schematic diagram of the utility model provision for disengagement.
Fig. 2 shows the use state diagram of the utility model provision for disengagement.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
With reference to figure 1, Fig. 2, the provision for disengagement of a kind of cylinder cover seat ring of the present utility model, the backstay connecting portion 10 and the seat ring connecting portion 13 that comprise coaxial connection, the termination of described seat ring auxiliary section is one to be the auxiliary section 130 of circular cone shape, it is described that 130 termination is provided with a circle projection 131 along its circumferencial direction in the auxiliary section, described seat ring connecting portion 13 is provided with through hole, described seat ring connecting portion 13 is along the elastomer 14 that is cut into quarter on its length direction, and the gap between the described adjacent resilient body 14 connects to described through hole; Also be provided with external diameter greater than the backstay 3 of described through hole, described backstay 3 inserts in the through holes, and and the screwed hole 101 that arranges of backstay connecting portion 10 cooperate.Provision for disengagement of the present utility model is when disassembling the seat ring 2 of cylinder cover 4, seat ring connecting portion 13 passes seat ring 2, make the inwall matched in clearance of seat ring auxiliary section 13 and seat ring 2, backstay 3 passes the guide hole of valve, and penetrate the through hole of seat ring auxiliary section 13, screw in the screwed hole 101 of seat ring connecting portion 10, form screw thread pair, the diameter of backstay 3 is greater than the diameter of through hole, thereby make elastomer 14 expand, in order to the auxiliary section 130 that is circular cone shape and the inwall of seat ring 2 are cooperated more closely, simultaneously, the termination that the projection 131 of 130 terminations, auxiliary section is blocked seat ring 2.At this moment, adopt the rear end face of hand hammer hammering backstay 3, the pressure that hand hammer produces evenly concentrates on the end face and seat ring hole of seat ring 2, simultaneously, because therefore the elasticity of elastomer 14 self can guarantee that seat ring can not damage cylinder head, thereby seat ring is removed in the process of disassembling.
The utility model preferably, the nominal diameter of described screwed hole 110 is less than the diameter of through hole, so that backstay 3 can pass through hole and screwed hole 110 cooperates.
The utility model more preferably, the gap between the described adjacent resilient body 14 is less than the diameter of seat ring auxiliary section 13 through holes.
The utility model is by preferred embodiment having carried out detailed explanation.Yet, by to the studying carefully of preamble, to the variation of each embodiment with to increase also be that one of ordinary skill in the art institute is apparent.Being intended that all these variations and increasing of applicant all dropped in the scope that the utility model claim protects.
