Description
Technical field
The utility model relates to automobile exhaust gas recirculated cooling system parts processing technique field, is specially a kind of cubing of automobile exhaust gas recirculated cooling system fan diffuser support.
Background technology
A kind of automobile exhaust gas recirculated cooling system fan diffuser support, its structure is seen Fig. 1 and Fig. 2, it is a kind of important installing component of automobile exhaust gas recirculated cooling system fan diffuser.The 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; Be one of critical component of motor car engine, therefore require high its manufacturing accuracy and installation accuracy.The fan diffuser support is as the important installing component of automobile exhaust gas recirculated cooling system fan diffuser; Its processing and manufacturing precision can directly have influence on the installation accuracy of fan diffuser; Therefore must detect its upper end square hole 13 position degree, upper end level and lower end arc surface 14 profile tolerances; Need respectively to need three secondary pick-up units to detect respectively in the past; Not only testing process is loaded down with trivial details for it, detection speed is slow, and divides and detect repeatedly positioning and clamping of workpiece needs for three times, is prone to cause positioning error and causes the inaccurate of testing result.
Summary of the invention
To the problems referred to above, the utility model provides a kind of cubing of automobile exhaust gas recirculated cooling system fan diffuser support, and its testing process that can solve the existence of fan diffuser support detection in the past is loaded down with trivial details, detection efficiency is low and the inaccurate problem of testing result.
Its technical scheme is such; It comprises installing plate; It is characterized in that: on the said installing plate fixed head is installed, the left and right sides of said fixed head is separately installed with folder energetically, and said fixed head front end is equipped with the workpiece limited block, the rear end is equipped with locating piece; The theoretical machined surface profile of support corresponding to be detected position, the both sides of said limited block has the support stopper slot; Said limited block vertically upper end is fixed with banking pin, and square hole detection and location pin is installed on the said locating piece, on the said workpiece limited block detection piece is installed also.
It is further characterized in that: both sides, the bottom end face of said detection piece is detection faces; Said two detection faces are respectively go side detection faces and not-go-end detection faces; Said go side detection faces is consistent with the theoretical profile face of support to be detected lower end circular arc, and said not-go-end detection faces is by the tolerance biasing of the theoretical profile face of support to be detected lower end circular arc; Said detection piece is set in turning axle, and said turning axle is fixed in said limited block, and said detection piece is spacing through nut; The said folder energetically through cushion block is fixed in said installing plate.
Adopt the cubing of the automobile exhaust gas recirculated cooling system fan diffuser support of the utility model; Its beneficial effect is: it carries out the first location of workpiece through the support stopper slot in the fixed head, workpiece limited block and banking pin; And workpiece is clamped in fixed head by the folder energetically of both sides; Square hole detection and location pin in the positioning and clamping process, on the locating piece directly detects the position degree of workpiece upper end square hole, and clamping is accomplished the back and detected piece through rotation and the lower end arc surface of workpiece is carried out the detection of profile tolerance, level on can detecting through the gap detection pin again; It can carry out three detections to clamping of workpiece; Not only simplified trace routine, improved detection efficiency, and reduced the positioning error that in the past caused, improved the accuracy of testing result owing to the multiple clamping detection.

Embodiment
See Fig. 3, Fig. 4 and Fig. 5; It comprises installing plate 1 the utility model; Fixed head 4 is installed on the installing plate 1, and the left and right sides of fixed head 4 is separately installed with and presss from both sides 3 energetically, and fixed head 4 front ends are equipped with workpiece limited block 5, the rear end is equipped with locating piece 10; The theoretical machined surface profile of support corresponding to be detected position, the both sides of workpiece limited block 5 has support stopper slot 12; Limited block 5 vertically upper end is fixed with banking pin 11, and square hole detection and location pin 9 is installed on the locating piece 10, also is equipped with on the workpiece limited block 5 to detect piece 6.The bottom both ends of the surface that detect piece 6 are detection faces; Two detection faces are respectively go side detection faces and not-go-end detection faces; Said go side detection faces is consistent with the theoretical profile face of support to be detected lower end circular arc, and said not-go-end detection faces is by the tolerance biasing of the theoretical profile face of support to be detected lower end circular arc; Detect piece 6 and be set in turning axle 8, turning axle 8 is fixed in workpiece limited block 5, and it is spacing through nut to detect piece 6; Press from both sides 3 energetically and be fixed in installing plate 1 through cushion block 2.
During detection; Support to be detected is positioned on the fixed head 4; Wherein the workpiece lower end is positioned in the support stopper slot 12, and the left and right sides presss from both sides 3 energetically support to be detected is pressed on the fixed head 4 then, and banking pin 11 is inserted in two square openings of support to be detected lower end; The square opening of support to be detected upper end is inserted in square hole detection and location pin 9 on the locating piece 10 (if the square opening of support to be detected upper end can't be inserted in square hole detection and location pin 9; Then the square hole location of this support upper end is defective, then no longer carries out all the other two detections), detect support lower end arc surface profile tolerance through rotating detection piece 6 again; Can be if detect the go side detection faces of piece 6 through then qualified, if the not-go-end detection faces of detection piece 6 can be through then defective; Adopt clearance ruler or clearance gauge to detect support upper end level again.
