Description
Technical field
The utility model relates to part of automobile engine erecting tools field, refers to a kind of engine flywheel lock device particularly.
Background technology
In engine, flywheel is installed on bent axle by threaded fastener, realizes the object of crank rotation flywheel driven rotation with this.During operation, need to use tightening tool to tighten above-mentioned threaded fastener, but certain moment of torsion can be applied to bent axle due to tightening tool, make flywheel along with crankshaft rotating, when subsequent operation, the problem cannot recognizing cap will be there is when tightening machine tights a bolt, for the installation of flywheel is made troubles.
In traditional installations, two the workman's co-operatings of general needs, a workman uses spanner to block flywheel to prevent it from rotating, an other workman uses the urgent bolt Flywheel of wrest fixing spanner on engine, such mounting means operating process is complicated, and workload is large, production efficiency is low, wasting manpower and material resources.
For addressing this problem, prior art produces a kind of special auxiliary mould to complete the installation of flywheel.Auxiliary mould as shown in Figure 1, this frock comprises fixture 9 and block piece 10, and during use, the fixture 9 of frock is fixed on engine cylinder-body, stops that flywheel rotates between the gear that the most advanced and sophisticated position of block piece 10 front end is stuck in flywheel.This frock can be good at the problem solving Conventional mounting techniques labor intensive material resources, and installs simple, easy to use.But this frock is because between the gear being directly fastened on flywheel, contact area is less, and when the rotary torsion of flywheel is larger, the damage of flywheel gear is easily caused in block piece 10 end, affects the service condition of whole engine.
Also patent is had to this has been improvement, it is the Chinese utility model patent of " auxiliary mould for engine flywheel is installed " by name of " CN202640292U " as the patent No., compared to the auxiliary mould of prior art, the utility model provides two location claws, larger with the auxiliary mould of the contact area rate prior art of flywheel, can avoid the damage of flywheel gear to a certain extent, but the contact area of two claws is still very little, may appoints for flywheel and so there is damage.The location structure of the utility model design is a locating dowel in addition, being extend in through hole by locating dowel is fixed on the cylinder body of engine, and during actual use, a locating dowel easily deflects, generation among a small circle may move, affect the installation of engine flywheel.
The Chinese utility model patent of " a kind of auxiliary mould of the flywheel for installing engine " by name that the patent No. is " CN203752088U ", the basis of above-mentioned patent has been made further improvement.The utility model comprises two locating dowels, more stable with the connection of engine cylinder-body.But also there are some shortcomings in the utility model, the utility model offers the through hole of a strip on body, flywheel is fixed through the installing hole on strip through hole and flywheel by bearing pin object, and in fact, do not have this installing hole above some flywheel, some are not had to the flywheel of installing hole, such installation is not all right certainly, therefore the utility model range of application is narrower, can not be applied to all engine flywheels and install.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provides a kind of engine flywheel lock device.
The technical solution of the utility model is: a kind of engine flywheel lock device, is characterized in that: comprise connecting plate; Described connecting plate is provided with one with the locating dowel corresponding with the through hole on engine cylinder-body of the circular arc flange face that flywheel rim is fitted and two vertical center web; Described flange face is provided with and is no less than three latches of answering with the gear mesh on flywheel; The axis of described locating dowel is vertical with the radial direction of flange face.
Further described circular arc flange face is positioned at the sidepiece of connecting plate.
Further described flange face is provided with and is no less than three continuous print latches.
Further described latch is taper type structure, and cone one end, the end is fixed on flange face, and its vertex of a cone and frustum sidepiece junction are entire fillet.
Further described latch uniform intervals is arranged on flange face.
The advantage that the utility model has has:
1, the utility model by arranging two locating dowels on connecting plate, can be more stable connecting plate is fixed on the cylinder body of engine, can not produce and to rock or mobile, fixing is more firm, and it is more accurate to install;
2, the flange face that the utility model is arranged is provided with the latch of multiple even arrangement, these latches can be fastened on the gear of flywheel uniformly, multiple latch adds contact area, lifting surface area increase avoids the destruction of latch to gear, solve prior art Problems existing, and install more convenient, locking is more firm, has great promotional value.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 2 ~ 5, a kind of engine flywheel lock device, comprises connecting plate 1, connecting plate 1 is square plate body structure, the side of connecting plate 1 caves inward and forms the flange face 2 of circular arc, and the depression radius of flange face 2 is identical with the radius of flywheel 7, and flange face 2 can be good at fitting with the edge of flywheel 7.Flange face 2 is provided with the continuous latch 4 to connecting plate 1 outer lug being no less than three, latch 4 uniform intervals is arranged on flange face 2, and latch 4 constructs arrangement according to the gear 8 on flywheel 7, and latch 4 can extend into the rotation stopping flywheel 7 between gear 8.
During actual use, flange face 2 can directly be offered along the sidepiece of connecting plate 1, arrangement as shown in Figure 4.In addition, flange face 2 also has other arrangement, and what need to ensure is the axis of flange face 2 and the axis being parallel of cylinder 5.
In addition, in order to prevent in installation process, latch 4 damages flywheel 7 gear 8, the latch 4 of the present embodiment is taper type, as shown in Figure 6, cone one end, the end is fixed on flange face 2, and the vertex of a cone and frustum sidepiece junction are entire fillet, can ensure that in the process that latch 4 contacts with gear 8, corner parts can not damage flywheel 7 like this.
In order to fixed connecting plate 1, the plate body of connecting plate 1 is provided with the locating dowel 3 corresponding with the through hole 6 on engine cylinder-body 5 of two vertical center web 1, the axis of locating dowel 3 is vertical with the radial direction of flange face 2.Locating dowel 3 extend in the through hole 6 on engine cylinder-body 5, is fixed on engine cylinder-body 5 by connecting plate 1, can be good at connecting plate 1 to fix.Two locating dowels 3 are more stable, avoid connecting plate 1 and deflect.
During use, first locating dowel 3 alignd with through hole 6, latch 4 aligns with gear 8 gap, then presses connecting plate 1 and be fixed on engine cylinder-body 5 by connecting plate 1, and latch 4 is fastened in gear 8 gap, completes the locking to flywheel 7.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
