The profile tolerance detector is characterized in that a fixing plate is mounted on the base; a locating pin is mounted on the fixing plate; the detector also comprises a profile tolerance detection clamp plate and a shell compaction device, wherein the profile of a detection surface of the profile tolerance detection clamp plate is consistent with the that of a theoretical molded surface of the shell to be detected, and the condition that the distance between the detection surface and the theoretical molded surface is the measurement reference value can be ensured; and the shell compaction device is mounted on the base. The profile tolerance detector provided by the utility model realizes fast detection and has high detection efficiency.
Description
Technical field
The utility model relates to the processing detection technique field of automobile exhaust gas recirculated cooling system parts, is specially a kind of profile tolerance cubing of automobile exhaust gas recirculated cooling system fan diffuser housing.
Background technology
Its effect of automobile exhaust gas recirculated cooling system fan diffuser is that the waste gas that motor car engine is discharged is sent to the cold filtration system; Again the gas delivery behind the cold filtration is postbacked motivation; Thereby effectively reduce the automobile emission amount, improve automobile fuel ecomomy; It is one of critical component of motor car engine, therefore its manufacturing accuracy, installation accuracy are required high, so need detect its housing profile tolerance.Mostly in the past is through three coordinate machine its profile tolerance to be detected, and its detection is loaded down with trivial details, and detection efficiency is low.
Summary of the invention
To the problems referred to above, the utility model provides a kind of profile tolerance cubing of automobile exhaust gas recirculated cooling system fan diffuser housing, and it is simple in structure, can carry out the detection of profile tolerance fast to housing, and is easy to detect.
Its technical scheme is such; It comprises pedestal; It is characterized in that: on the said pedestal fixed head is installed, on the said fixed head register pin is installed, it comprises that also profile tolerance detects clamp and housing hold down gag; The detection faces profile of said profile tolerance detection clamp is consistent with the theoretical profile of housing to be detected and guarantee that said detection faces and said theoretical profile distance are the measuring basis value, and said housing hold down gag is installed on the said pedestal.
It is further characterized in that: said profile tolerance detects clamp and comprises that the housing outline detects clamp and clamp is detected on the port plane; The installation end that said housing outline detects clamp is installed on holder through rotational pin, and said holder is installed on said pedestal; Said housing outline detects clamp and comprises detection clamp one, detects clamp two and detect clamp three; Said detection clamp one installation direction is vertical with housing roundlet mouth direction to be measured; Said detection clamp two is installed along the diametric(al) of housing to be measured, and the installation direction of said detection clamp three is vertical with the installation direction of said detection clamp two; When housing clamping to be measured detects, said test card one with detect clamp two stiff end lock onto bearing through wing bolt, said bearing is installed on said fixed head; The workpiece roundlet mouth positioning table terrace place that clamp is installed on said fixed head is detected on said port plane; Said housing hold down gag comprises energetically folder, and said the folder energetically through holder energetically is installed on said pedestal.
Adopt the profile tolerance cubing of the utility model; Its beneficial effect is: its detection is quick and convenient; It locatees housing to be measured through register pin and roundlet mouth location-plate; Compress housing to be measured through clamp device energetically; It is consistent and guarantee that said detection faces and said theoretical profile distance are the measuring basis value that the profile tolerance that is provided with detects the theoretical profile of clamp detection faces profile and housing to be detected, adopts to end the distance that drift carries out between profile tolerance detection clamp and the housing outline profile to be measured and can accomplish detection, and its detection is quick, detection efficiency is high.
