Abstract
The utility model discloses a cylinder pad with a bolt-hole edge, which comprises a pad body with a circular arc transition, wherein the pad body is provided with a cylinder hole, a water pore, a positioning hole, an installing hole and a tappet hole, wherein the positioning hole is a kidney-shaped hole. Both sides of the pad body are arranged with two protruding side ears respectively and the side ears are provided with bolt-holes respectively. The two surfaces of the pad body are coated with a black electrophoretic coating respectively and the black electrophoretic coating ranges from 0.02 mm to 0.04 mm in thickness. The cylinder hole is provided with a steel-hole retainer. The positioning hole, the tappet-hole and the near installing hole are coated with a Teflon coating. The cylinder pad with the bolt-hole edge has the advantages that the pad body is convenient to process and manufacture so that production cost can be reduced, the whole pad is sealed to a certain degree through the structure of the black electrophoretic coating so that partial sealing performance is enhanced, and the installing and positioning performance is good through structures of the side ears and bolt-holes.
Description
Technical field
The utility model relates to cylinder seal technical field, relates in particular to a kind of head gasket with bolt hole bound edge.
Background technique
The effect of head gasket is the microscopic void of filling up between cylinder block and head, guarantees that there is good sealing at junction plane place, and then guarantees that the sealing of firing chamber prevents that cylinder leakage tester and water jacket from leaking.Existing gasket structure design is improper, in order to increase its sealability, mostly adopts multi-layer structure, and multi-layer structure certainly exists certain drawback, as manufacturing inconvenience, finished product is high, in order to reduce production costs, therefore need the structure of individual layer shim body to improve.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of head gasket with bolt hole bound edge is provided.
The utility model is achieved through the following technical solutions:
A kind of head gasket with bolt hole bound edge, include the excessive shim body of circular arc, in described shim body, be distributed with cylinder-bore, water hole, positioning hole, mounting hole, tappet bore, it is characterized in that: described positioning hole is waist shaped hole, the both sides of described shim body are respectively equipped with picking up the ears of two outer protrusions, on described picking up the ears, be respectively equipped with bolt hole, on the two sides of described shim body, be coated with respectively black electrophoretic coating, the thickness of described black electrophoretic coating is 0.02-0.04mm, described cylinder-bore place is provided with steel hole guard ring, described positioning hole, on tappet bore and near mounting hole, be coated with polytetrafluorethylecoatings coatings.
The utility model has the advantages that:
The utility model is excessive by the circular arc of shim body, can facilitate being processed into of shim body, reduced cost of production, by the structure of black electrophoretic coating, whole pad entirety is carried out to sealing to a certain degree simultaneously, on cylinder hole guard ring by cylinder-bore and positioning hole, tappet bore and near mounting hole, be coated with the structure of polytetrafluorethylecoatings coatings, strengthened local sealability, by picking up the ears and the structure of bolt hole, it is good that it installs positioning stablity performance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of head gasket with bolt hole bound edge, include the excessive shim body of circular arc 1, in shim body 1, be distributed with cylinder-bore 2, water hole 3, positioning hole 4, mounting hole 5, tappet bore 6, positioning hole 4 is waist shaped hole, what the both sides of shim body 1 were respectively equipped with two outer protrusions picks up the ears 7, pick up the ears on 7 to be respectively equipped with bolt hole 8, on the two sides of shim body 1, be coated with respectively black electrophoretic coating 9, the thickness of black electrophoretic coating 9 is 0.02-0.04mm, cylinder-bore 2 places are provided with steel hole guard ring 10, positioning hole 4, on tappet bore 6 and near mounting hole 5, be coated with polytetrafluorethylecoatings coatings 11.
