Abstract
The utility model relates to an engine running-in handcart cushion block structure. With the engine running-in handcart cushion block structure of the utility model adopted, the problem of insufficient strength or high possibility of causing abrasion to an engine of an existing running-in handcart cushion block can be solved. The cushion block comprises a cushion block body; the surface of the cushion block body is divided into a first surface and a second surface; the second surface is higher than the first surface; the two surfaces form a ladder structure; and a gasket is fixed on the second surface. Two parts are assembled to form the cushion block; the cushion block body is made of a hard material, such that the overall strength of the cushion block can be guaranteed; the gasket is embedded in the cushion block body, and the gasket is made of a material softer than a cylinder body of the engine; and engine legs are mounted on the gasket, and the gasket will not cause abrasion to the engine, and therefore, the surface of the engine can be protected. Thus, overall hardness can not only be ensured, and the hardness of joints can satisfy test requirements.
Description
Technical field
The utility model relates to automotive engine test technical field, and relating in particular to a kind of both proof strengths has the engine break-in dolly cushion block structure that meets hardness requirement.
Background technology
Motor car engine needs to carry out hot running-in before the test working of dispatching from the factory; generally that engine is fixed on a break-in dolly; between engine and break-in dolly, be generally all provided with cushion block, cushion block can play buffer action in the period of adjustment by re-generating engine, and protection motor support face is without wearing and tearing.Cushion block is easy to wear, can cause engine from dolly, to drop in the period of adjustment, so examination is normally ground in the break-in of the good bad influence engine thermal of break-in dolly cushion block when serious.
Because engine cylinder-body crankcase hardness is 80 ~ 110HB, can not use than cylinder block-crankcase also hard material as cushion block, existing cushion block has employing nylon, 45 steel and leather substance, but existent defects all, 1. cushion block adopts nylon material, and nylon hardness is low, hardness is to have reached requirement, intensity is not enough, and engine thermal was shaken during the period of adjustment, to cushion block especially nylon cushion block wearing and tearing especially severe.2. cushion block adopts 45 Steel materials, and steel are harder than aluminium alloy, causes engine scuffing, can not use than cylinder block-crankcase also hard material as cushion block.3. cushion block adopts leather substance, and leather thickness is excessive, and rigidity is inadequate, and the replacement cycle is short.In sum, these three kinds of materials are all not suitable as cushion block material.
As the patent No. Chinese utility model that is 201020209400.0, a kind of no-load break-in tooling of vehicular starting motor is disclosed, it comprises the pedestal that is provided with deep-slotted chip breaker, the front side of pedestal, rear side are respectively arranged with adjustable for height front pods and rear cushion block, this front pods and rear cushion block adopt wear-resisting material to make as textolite, although this textolite can not cause wearing and tearing to starter, the intensity of this textolite is not very enough.
Summary of the invention
The utility model has mainly solved existing break-in dolly cushion block insufficient strength or easily engine has been caused the problem of wearing and tearing, provides a kind of both proof strengths to have to meet the engine break-in dolly cushion block structure of hardness requirement.
The utility model solves the technical scheme that its technical matters adopts: a kind of engine break-in dolly cushion block structure, comprise cushion block main body, described cushion block body surfaces is divided into first surface and second surface two parts, described second surface height is lower than first surface, two surfaces form step structure, are fixed with pad on second surface.In the utility model, cushion block being divided into two parts installation forms; this cushion block main body adopts relatively hard materials to be made; make like this cushion block bulk strength be guaranteed; in cushion block main body, set pad; this pad adopts the softer material of ratio engine cylinder body to make; engine foot is arranged in this pads placement, and pad can not cause wearing and tearing to engine, has protected Engine Surface.The utility model cushion block had both guaranteed integral hardness, made again junction hardness meet test request.
As a kind of preferred version, cushion block body surfaces be take axis and as boundary, surface is divided into first surface and second surface.
As a kind of preferred version, the shape of described pad is identical with second surface shape, and after installing, gasket surface and first surface flush.Pad is installed integral body rear and cushion block main body formation flush.
As a kind of preferred version, on second surface, be provided with fixed orifice one, on pad, be provided with the mounting hole corresponding with fixed orifice one, pad is fixed on second surface by rivet.Pad adopts riveted joint form to be connected with cushion block main body, reduces cost.
As a kind of preferred version, described cushion block main body adopts 45 steel to be made, and pad adopts red copper to be made.Cushion block main material is harder, has guaranteed the intensity of cushion block integral body, and pad adopts red copper material, and red copper material has good Dao electricity ﹑ Dao Re ﹑ ductility and corrosion stability, and during engine break-in, ductility is good, incrust.
As a kind of preferred version, described cushion block main body adopts 45 steel to be made, and pad adopts red copper to be made.
As a kind of preferred version, the thickness of described pad is 3mm ~ 7mm.This thickness had both met request for utilization, had also saved material simultaneously.
As a kind of preferred version, on described first surface, be provided with some fixed orifices two that are connected with break-in dolly, described fixed orifice two cross sections are T shape.Set bolt can integral body be screwed in fixed orifice two, has guaranteed cushion block surfacing.
The utility model has the advantages that: cushion block is divided into two parts installation and forms; this cushion block main body adopts relatively hard materials to be made; make like this cushion block bulk strength be guaranteed; in cushion block main body, set pad; this pad adopts the softer material of ratio engine cylinder body to make; engine foot is arranged in this pads placement, and pad can not cause wearing and tearing to engine, has protected Engine Surface.So both guarantee integral hardness, and made again junction hardness meet test request.
