[0026] Please refer to Figures 1-4 The utility model provides a kind of engine rubber sealing piece detection device, including annular seat 100, the inner side of annular seat 100 is rotatably installed with carousel 101, the outer surface of annular seat 100 is provided with the drive mechanism 200 that can drive carousel 101 angular intermittent rotation.The upper surface of carousel 101 is coaxially installed with multiple fixed columns 102 at equal angle, the top of fixed column 102 is installed with conical column 103, and the outer surface of fixed column 102 is provided with heating ring 104.The inside of fixed column 102 and conical column 103 is jointly provided with through hole 105, and the bottom of annular seat 100 is installed with detection mechanism 106, and the lower surface of carousel 101 is provided with the connecting mechanism 300 for making several through holes 105 all communicate with detection mechanism 106.The upper surface of annular seat 100 is provided with pressure tight inflation mechanism 400.

[0027] In use, the detection personnel first nest the sealing ring outside the conical column 103, then drive the sealing ring to rotate to the lower side of the compression and inflation mechanism 400 by the driving mechanism 200, and then the sealing ring is pressed and inflated by the compression and inflation mechanism 400, so that the sealing ring can be expanded and slid down to the heating ring 104 along the inclined surface of the conical column 103, and the heating ring 104 is heated, which can simulate the use environment of the sealing ring on the engine, and then the gas enters the detection mechanism 106 through the through hole 105 and the connecting mechanism 300, so as to realize the purpose of sealing detection. The arrangement of the connecting mechanism 300 enables several through holes 105 to share one detection mechanism 106, thereby reducing the complexity of the structure and reducing the cost of the equipment.

[0028] The structure and working principle of the detection mechanism 106 are consistent with those of the comparative patent, so no more description is made here.

[0029] Preferably, the driving mechanism 200 comprises a servo motor 201 mounted on the outer surface of the annular seat 100, and the end of the output shaft of the servo motor 201 is provided with a driving gear 202, and the outer surface of the rotating disc 101 is provided with a driven gear 203 which is in meshing connection with the driving gear 202.

[0030] By starting the servo motor 201, the output shaft drives the driving gear 202 to rotate, and since the driving gear 202 and the driven gear 203 are in meshing connection with each other, the rotating disc 101 can be driven to rotate intermittently at equal angles.
