Abstract
The utility model discloses a flywheel hardness testing fixture used for testing hardness of flywheels irregular in undersurface shape. The flywheel hardness testing fixture comprises a discal body which is provided with an inner concave cavity and a through hole communicated with the undersurface of the inner concave cavity, a flywheel is flatwise placed in the inner concave cavity, a kidney-shaped hole is arranged at a position, deviating from the center, of a flywheel web, a press plate is arranged on the upper plane of the flywheel, and a bolt connecting member is arranged between the undersurface of the body and the press plate and penetrates through the through hole and the kidney-shaped hole to tightly press the flywheel. By flatwise placing the flywheel on the body which can be guaranteed to be smoothly placed on a tester workbench, accuracy of harness measuring of the flywheel is guaranteed.
Description
Technical field
The utility model relates to a kind of flywheel hardness test frock.
Background technology
Flywheel causes when carrying out hardness test owing to its side view is irregular, is difficult to entirely be placed on the worktable of test machine, to such an extent as to influenced the accuracy of hardness measurement.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of flywheel hardness test frock that can guarantee flywheel hardness measurement accuracy is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of flywheel hardness test frock, be used for the irregular flywheel tested for hardness of bottom shape, the body that comprises plate-like, the through hole that described body has inner cavity and communicates with the inner cavity bottom surface, flywheel lies in the inner cavity, the flywheel web departs from center position and has mounting hole, the plane is provided with pressing plate on the flywheel, be provided with bolt connection piece between body bottom surface and the pressing plate, bolt connection piece passes described through hole and mounting hole compresses flywheel.
The beneficial effects of the utility model are: the utility model is by lying in flywheel on the body, and this physical efficiency guarantees entirely to be placed on the test machine worktable, thereby has guaranteed the accuracy of flywheel hardness measurement.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. flywheels, 2. bodies, 3. inner cavities, 4. through holes, 5. mounting holes, 6. pressing plates, 7. bolt connection pieces among the figure
Embodiment
By reference to the accompanying drawings the utility model is further described now.The synoptic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of flywheel hardness test frock as shown in Figure 1, be used for irregular flywheel 1 tested for hardness of bottom shape, the body 2 that comprises plate-like, the through hole 4 that described body 2 has inner cavity 3 and communicates with inner cavity 3 bottom surfaces, flywheel 1 lies in inner cavity 3, and flywheel 1 web departs from center position and has mounting hole 5, and the plane is provided with pressing plate 6 on the flywheel 1, be provided with bolt connection piece 7 between body 2 bottom surfaces and the pressing plate 6, bolt connection piece 7 passes described through hole 4 and mounting hole 5 compresses flywheel 1.During test, only needing has the body 2 of flywheel 1 to be placed on the test machine worktable clamping, and bolt connection piece 7 parts that body 2 bottom surfaces are exposed depart from the test machine worktable, namely avoid plane on the test machine worktable, can accurately measure flywheel 1 hardness, because flywheel 1 is lain on the body 2, and body 2 can guarantee entirely to be placed on the test machine worktable, thereby has guaranteed the accuracy of flywheel 1 hardness measurement.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
