The rear support disclosed by the utility model has the advantage of avoiding frequently replacing the rear support of the engine pedestal in a pedestal test.
Description
Technical field
The utility model relates to engine test and uses device, relates in particular to a kind of being used for to support behind the engine pedestal that engine rig test uses.
Background technology
In the prior art, when carrying out engine rig test, need it be linked to each other with dynamometer machine with the rear end of bracing or strutting arrangement from the supported underneath engine cylinder-body.Between engine and the dynamometer machine, both can directly link to each other, also can link to each other with clutch coupling and wheel box earlier, be connected with dynamometer machine again through engine.
When engine directly is connected with dynamometer machine, support behind the engine pedestal of prior art, generally include base plate and side plate, side plate is provided with bolt hole, also has bolt hole on the rear end face of the cylinder block of engine.Through bolt support fixation behind engine cylinder-body rear end and the stand is connected so that the engine cylinder-body rear end is supported.
Yet the subjects on stand is when promptly engine condition changes; When for example between diesel motor not of uniform size and petrol engine, changing, because the difference of volume, the screw hole of engine cylinder-body rear end is arranged different; The screw hole spacing of same horizontal level is also different, therefore needs with supporting behind the different engine pedestals, and engine will often be gone up lower stage again when testing; Just must support behind the frequent change engine pedestal, waste time and energy.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model is, supports after a kind of engine pedestal is provided, and directly is connected the technical matters that supports behind the need frequent change engine pedestal when carrying out bench test to solve prior art engine and dynamometer machine.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
Support behind a kind of engine pedestal; Be used for when carrying out Engine Block Test, supporting the rear end of said engine and engine is directly linked to each other with dynamometer machine; Support behind the said engine pedestal and comprise: base, go back the two groups of through holes that are used to connect terrace iron that are provided with of symmetry on the said base; Back up pad; Be vertically connected at said base top; The top of said back up pad has the lower concave part that is used to dodge engine flywheel; The bottom of said lower concave part is the semicircle arcuation, and the said back up pad of said lower concave part both sides is provided with and is used for the slotted hole that matches with the fixed orifice of engine cylinder-body rear end face.
Support behind the engine pedestal of the utility model, preferred, on the inboard said back up pad in said slotted hole below also symmetry be provided with the pair of screws hole.
Support behind the engine pedestal of the utility model, preferred, said base is arranged at a side of said back up pad.
Support behind the engine pedestal of the utility model, preferred, said base is welded in said back up pad.
The beneficial effect of the utility model is; Support behind the engine pedestal of the utility model; Be applicable to the stand that adopts direct-connected mode to be connected between engine cylinder-body rear end face and stand dynamometer machine; Can solve a difficult problem that supports behind the frequent change engine pedestal, and solid and reliable, be applicable to vapour, the bavin engine model of different model, different size.
Description of drawings
Fig. 1 looks synoptic diagram for the master who supports behind the engine pedestal of the utility model embodiment.
Fig. 2 looks synoptic diagram for a left side of supporting behind the engine pedestal of the utility model embodiment.
Embodiment
The exemplary embodiments that embodies the utility model characteristic and advantage will be described in detail in following explanation.Be understood that the utility model can have various variations on various embodiment, the scope of its neither disengaging the utility model, and explanation wherein and appended accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the utility model.
As depicted in figs. 1 and 2; Support behind the engine pedestal of the utility model embodiment; Be used for when carrying out Engine Block Test from supported underneath engine cylinder-body rear end face and engine is directly linked to each other with dynamometer machine, said engine in this instructions does not comprise clutch coupling and wheel box.
Above-mentioned engine; For example be 486 type gasoline engines and 493 diesel engines; The rear end of the cylinder block face shape of two kinds of engines is similar, but the volume of 493 model diesel engines is a bit larger tham the volume of 486 type gasoline engines, and therefore the spacing of the fixed orifice of the vertical center of two kinds of engine cylinder-body rear ends is different.The fixed orifice of engine cylinder-body rear end is for example for being used to connect the bolt hole of clutch coupling.And except that the fixed orifice of vertical center, below vertical center, 493 diesel engines also have one group of symmetrical bolt hole, and do not have bolt hole on the same position of 486 type gasoline engines.
For the engine with top two kinds of models adapts, support behind the engine pedestal of the utility model embodiment, as depicted in figs. 1 and 2, comprise base 1 and back up pad 2, base 1 is vertical each other with supporting seat 2, and base 1 is welded in the bottom of supporting seat 2.Base 1, symmetry be provided with two groups of through holes 6 that are used to connect terrace iron, through hole 6 is used to pass the vertical supporting leg of stand terrace iron, so that dismountable fixed connection the between base 1 and the terrace iron.
Back up pad 2 is vertically connected at base 1 top, and the top of back up pad 2 has lower concave part 3, and lower concave part 3 is used to dodge engine flywheel, interferes between flywheel and the back up pad 2 when avoiding actual tests.The bottom of lower concave part 3 is the semicircle arcuation, and the vertical extension of certain altitude can be arranged on the semi arch.
The back up pad 2 of lower concave part 3 both sides is provided with slotted hole 4, and slotted hole 4 along continuous straight runs extend, and match with the fixed orifice with the engine cylinder-body rear end face; Bigger for the fixed orifice spacing; 493 diesel engines for example can be connected two outsides relatively of slotted hole 4, and less for the fixed orifice spacing; 486 type gasoline engines for example then can be connected two relative inner of slotted hole 4.
As depicted in figs. 1 and 2, on the inboard back up pad 2 in slotted hole 4 belows also symmetry be provided with pair of screws hole 5, be used for connecting the pair of bolts hole below the vertical center of 493 diesel engines through bolt.
Support behind the engine pedestal of the utility model, base 1 both can only be arranged at a side of back up pad 2, can be convenient to the rotation supported behind the engine pedestal, was convenient to take out from below, engine rear end; Base 1 also can be arranged at the both sides of back up pad 2, make support behind the engine pedestal more firm.
When carrying out the bench test of 493 diesel engines; In slotted hole 4 and screw hole 5, all wear bolt; With the rear end face of fixing 493 diesel engine cylinder bodies, and when carrying out the bench test of 486 diesel engines, only need in slotted hole 4, to wear the rear end face of its cylinder body of bolt.Therefore, when these two kinds of engines hocket bench test, need not to support behind the frequent change engine pedestal again, improved test efficiency.
Those skilled in the art should recognize change and the retouching of under the situation of scope that does not break away from the appended the utility model that claim disclosed of the utility model and spirit, being done, and all belong within the protection domain of claim of the utility model.
