Description
Technical field
The utility model relates to the engine adjustable supports.
Background technology
The Engine Block Test technology is an important component part of automotive test technology, also is a most complicated part.When carrying out Engine Block Test, general all carry out at the threst stand of special use.By some special-purpose coupling arrangements engine is fixed on the test-bed during test, and tests after connecting required electricity, gas, water, oil and required instrument and equipment.Stationary engine generally adopts welding to support in the prior art, and highly non-adjustable, the height unanimity between the assurance equipment needs the finishing supporting surface, and can only be supporting with a kind of engine, does not accomplish interchangeability, and versatility is poor.
In recent years, some producer has also processed some adjustable for height motor support, similar bolt and nut pair, but when adjusting height, supporting surface is and then rotation also, the surface of contact of abrasion engine, and adjustable extent is little, and intensity is bad, can produce the partial points resonance effect when engine running, effect is not very desirable, does not realize the three-dimensional adjustable of single support yet.Also have some motor support, for example application number is 200920230317.9 the flexible adjustable supports of the disclosed a kind of engine rig test of Chinese utility model patent, comprise frame, frame is provided with the sleeve with upward opening, the opening of sleeve can tighten up or loosen, guiding is equipped with support bar in the sleeve, and the support bar upper fixed has the pallet seat, and the support pallet is fixedly arranged on the pallet seat.In addition, also be provided with the perforate of extending up and down in one side of supporting pallet on the pallet seat, is connected with the shaft component of rotation of the screw rod upper end of a upper and lower settings in the perforate, is provided with the structure of the similar shaft shoulder on the screw rod at pallet seat lower surface, for the pallet seat being applied the power that makes progress.The support pallet is stretched out in the screw rod upper end, and is connected with the drives structure of drive screw turns.Also be installed with on the frame with screw rod on the adaptive nut seat of threaded portion, screw rod rotates and is assemblied in the nut seat.
During use, the opening of sleeve is loosened, by adaptive instrument, for example spanner can make screw rod rise by the drives structure rotating screw bolt, and passes through shaft shoulder structure with the pallet seat and support pallet jack-up, and support bar upwards moves in sleeve simultaneously.After adjusting to correct position, tighten up the opening of sleeve, the relative sleeve of support bar is fixed, can bring into play supporting role, realize height control.But, supports pallet and need rely on the screw rod jacking to realize with the rising of engine it on, and the screw rod height is understood respective change in the adjustment, is not easy to operate drive unit.When the adjustment that needs high height, screw rod need move up than long distance, owing to have one section level interval between the support bar of this device and the screw rod, the screw rod of arranging at side drives heavy weight engine, support pallet and support bar moves up and down when regulating, requirement of strength to apparatus structure is higher, easy deformation, and stability of strutting system is poor, can make to adjust and cause difficulty, and structure inadequately compact, take up room big; In addition, be to realize that by the shaft shoulder structure friction force is big, also makes troubles to adjustment between screw rod and the pallet seat.For heavy-duty engine, the problems referred to above will be more outstanding.
The utility model content
