Abstract

The invention relates to a multifunctional mounting bolt which comprises a bolt head and a threaded rod. The bolt head is a hexagonal cylinder, a countersink hole is formed in the middle of the bolt head, a plurality of protrusions are evenly distributed on the side wall of the countersink hole, and the protrusions are in a strip shape and are formed in the axial direction of the threaded rod. The sections of the protrusions are conical, the tops of the protrusions point to the axis of the threaded rod, the roots of the adjacent protrusions are connected, and included angles are formed. Multiple dismounting and mounting modes can be provided for parts, convenience is brought for the operation of operators, and meanwhile the manufacturing cost of automobiles is lowered.

Description

A kind of multi-functional construction bolt
Technical field
The present invention relates to the bolt that a kind of automobile is used, especially relate to a kind of multi-functional construction bolt for engine power conveyor member.
Background technique
At present automobile can be divided into two kinds of patterns of manual gear and automatic catch (or hand, from one) by mode of operation, and in actual production, the bolt that manual gear flywheel is installed be often outer six square bolts, and the bolt of installation automatic catch drive plate is usually interior corner bolt.There is two states in the structure of bolt, the installation while being unfavorable for engine assembly; In the time that motor needs repairing, be unfavorable for maintenance man's dismounting, delay engineering time; On the production line of assembling motor and gearbox, need to be equipped with the bolt screwing machine of different model; The cost that has increased manufacturing mechanism drops into; There is two states in the bolt of identical function effect, is unfavorable for the unitized management of engine component.
Summary of the invention
Main purpose of the present invention is to provide a kind of installation for engine power conveyor member, the final multi-functional construction bolt that reduces manufacture cost that arrives.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of multi-functional construction bolt, comprise bolt head and threaded stem, this bolt head is six sides' Cylindrical object, it is characterized in that: bolt head middle part is provided with counterbore, on the sidewall of counterbore, be evenly distributed with several projections, this projection is bar shaped, along the axial setting of threaded stem; Convex cross section is taper, and threaded stem axle center is pointed at top, and the root of adjacent protrusion joins, and forms angle.Can for increasing multiple disassemble or assemble mode, part (can meet the dismounting of internal angle wrench and interior plum blossom shaped spanner, can meet again the dismounting of the instruments such as interior angle sleeve and open-end wrench and adjustable spanner), when bringing convenience for operator's operation, reduce automobile making cost.
As preferably, for adjacent protrusion, in the same plane in both conical surfaces in outside.Be convenient to the fitting area between raising and setting tool, raising can apply dynamics, also the stationarity of convenient operation.
In order to improve holding strength, as preferably, bolt head bottom arranges supporting disk, and supporting disk is cylindrical body.
As preferably, described counterbore in-and-out bolt head, and extend in threaded stem or connect threaded stem, projection is extended with counterbore.The degree of depth that raising instrument can go deep into, raising can apply dynamics, bears more high-intensity driving torque.
As preferably, described threaded stem is provided with guide hole along axle center, and this guide hole is tri-angle-holed or polygon hole, and guide hole communicates with counterbore bottom surface; In guide hole, be provided with rhabodoid, rhabodoid one end embeds guide hole, and the other end stretches out in counterbore, and external part arranges column head, the peripheral dimension of column head is consistent with bolt head, be highly at least a times of bolt head height, column head is provided with hexagonal shaped counterbore in outer end.The structure that rhabodoid embeds, can be integrally formed structure with threaded stem, also can extract; The darker place in mounting point, by the installation and removal of rhabodoid operating screw.
Therefore, the present invention is rational in infrastructure, is particularly useful for the installation of engine power conveyor member, the final reduction manufacture cost that arrives.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of the present invention.
Accompanying drawing 2 is a kind of structural representations of bolt head.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, technological scheme of the present invention is described in further detail.
Embodiment 1: a kind of multi-functional construction bolt of the present invention, as shown in accompanying drawing 1, accompanying drawing 2, comprise bolt head 3 and threaded stem 1, and this bolt head 3 is six sides' Cylindrical object.Bolt head 3 bottoms arrange supporting disk 2, and supporting disk 2 is cylindrical body.
Bolt head middle part is provided with counterbore 4, is evenly distributed with several projections 5 on the sidewall of counterbore 4, and this projection 5 is bar shaped, along the axial setting of threaded stem 1; Projection 5 cross sections are taper, and threaded stem 1 axle center is pointed at top, and the root of adjacent protrusion 5 joins, and forms angle.For adjacent protrusion 5, in the same plane in both conical surfaces 51 in outside.
Counterbore 4 in-and-out bolt heads 3, and extend in threaded stem 1 or connect threaded stem 1, projection 5 is extended with counterbore 4.
Embodiment 2: threaded stem 1 is provided with guide hole along axle center, and this guide hole is tri-angle-holed or polygon hole, and this guide hole communicates with counterbore 4 bottom surfaces; In guide hole, be provided with rhabodoid, rhabodoid one end embeds guide hole, and the other end stretches out in counterbore 4, and external part arranges column head, the peripheral dimension of column head is consistent with bolt head 3, be highly at least a times of bolt head 3 height, column head is provided with hexagonal shaped counterbore in outer end.All the other are with embodiment 1.
When the present invention uses, no matter be manual or automatic transmission, all adopt the bolt of same specification, adopt the mode of installation and removal of the same race.
The present invention has following beneficial effect: when can increasing multiple disassemble or assemble mode (dismounting that can meet internal angle wrench and interior plum blossom shaped spanner can meet again the dismounting of the instruments such as interior angle sleeve and open-end wrench and adjustable spanner) and bring convenience for operator's operation for part, reduce automobile making cost; By unified part feature, this bolt is realized to unitized standard, can be used as standard piece and use; By after this bolt standardization, the mounting type of all engine power conveyor members can be carried out to standardization.
