Abstract
The utility model relates to an irregular bolt for improving the height of a cylinder boss and belongs to the technical field of automobile engines. The irregular bolt comprises a bolt head and a screw provided with threads, wherein the bolt head is formed by a disc-shaped heat portion and a neck portion with a hexagonal section, the front end face of the head portion is of a plane structure, a bolt hole is axially formed in the center of the front end face of the head portion, a limiting ring is arranged between the bolt head and the screw, a limiting surface of the limiting ring is of a plane structure, and a section of cylindrical heightening section is arranged between the limiting ring and the bolt head. The irregular bolt is ingenious in design and easy and convenient to operate, the irregular bolt is fixed on the boss needing to be heightened, and other parts needing to be fixed and assembled are fixedly screwed in a bolt hole in the rear end of the irregular bolt through the irregular bolt, so that the aim of lifting the boss and fixing other parts can be achieved.
Description
Technical field
The utility model belongs to motor car engine component technical field, relates to a kind of for the heterotypic bolt that promotes cylinder body boss height particularly.
Background technique
At present at motor in the proposal plan process, handling experiment problem and proposing in the process of the interim corrective measure of checking, often exist the boss height that needs on the interim increase engine cylinder-body to satisfy the fixing and assembling of other parts, if revise the boss height of component, need to revise mould and manufacture a product again, so not only the cycle is longer, also need to change component at motor, and just temporary measure verifies that whether tentative plan is feasible effective, might not directly implement at mould.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, and a kind of heterotypic bolt that is used for promoting cylinder body boss height simple to operation is provided.It can increase the boss height to satisfy the fixing and assembling of other parts temporarily.
The technical solution adopted in the utility model is: it comprises bolt head and is provided with the screw rod of screw thread, described bolt head is that hexagonal neck constitutes by discoidal head and cross section, the front-end face of described head is plane structure, head front-end face center is axially arranged with bolt hole, be provided with limited ring between described bolt head and the screw rod, the confined planes of limited ring is plane structure, is one section cylinder section of increasing between described limited ring and the bolt head.
In the such scheme, this heterotypic bolt is pressed the corresponding screw rod of bolt hole size design of cylinder body convex platform, the confined planes of limited ring is used for fitting with former boss plane, the middle part arranges one section cylinder section of increasing by the boss size, the hexagonal flanged surface of neck is used for tightening of spanner, the plane structure of head front-end face is used for fitting with quilt applying part plane,, makes by the applying part and fixes by bolt and this heterotypic bolt to the auger shell keyhole at head front-end face central shaft.
The utility model design is ingenious, simple to operation, this heterotypic bolt is fixed on the required boss that increases, with bolt required other parts fixing and assembling fixedly are tightened in the bolt hole of heterotypic bolt rear end, so just reached lifting boss height, the purpose of fixing other parts.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not constitute restriction to the utility model.
As shown in Figure 1, the utility model comprises that bolt head is not shown with the screw rod 2(screw thread that is provided with screw thread), bolt head is that hexagonal neck 5 constitutes by discoidal head 6 and cross section, the front-end face of head 6 is plane structure, head 6 front-end face centers are axially arranged with bolt hole 7, be provided with limited ring 3 between bolt head and the screw rod 2, the confined planes 3.1 of limited ring 3 is plane structure, is one section cylinder section of increasing 4 between limited ring 3 and the bolt head.
The utility model is pressed the corresponding screw rod 2 of bolt hole size design of cylinder body 8 convex platforms 9, the confined planes 3.1 of limited ring 3 is used for fitting with former boss 9 planes, the middle part arranges one section cylinder section of increasing 4 by boss 9 sizes, the hexagonal flanged surface of neck 5 is used for tightening of spanner, the plane structure of head 6 front-end faces is used for fitting with quilt applying part plane, to auger shell keyhole 7, make by the applying part fixing by bolt and heterotypic bolt 1 at head 6 front-end face central shafts.
As shown in Figure 2, the boss 9 of cylinder body 8 need increase to fix other parts temporarily, utilize the hexagonal flanged surface of heterotypic bolt 1 neck 5, with spanner screw rod 2 screw-ins are tightened cylinder body 8 convex platforms 9, the confined planes 3.1 that guarantees the limited ring 3 of heterotypic bolt 1 is fitted with the plane of boss 9, has so just increased the height of the boss 9 on the cylinder body 8.
As shown in Figure 3, with chain shell 10 press close to heterotypic bolt 1 bolt head, the through hole 11 on the chain shell 10 aligns with the bolt hole 7 of heterotypic bolt 1, with the fixing chain shell 10 of bolt 12, screw-in bolt hole 7 has so just reached the fixedly purpose of chain shell 10.
As shown in Figure 4, after fixedly finishing, heterotypic bolt 1 is fixed on by being threaded on the cylinder body 8 required boss that increase 9, and the chain shell 10 that need be fixed is close to heterotypic bolt 1, and is fixing by bolt 12, reaches like this to promote boss height, the fixedly purpose of chain shell.
The content that this specification is not described in detail belongs to related domain professional and technical personnel's known prior art.
