Abstract
The utility model discloses a taper-hole keyway gauge including a circular truncated cone, a cylinder, a key pin and a keyway. The cylinder is fixedly arranged on the bottom face of the circular truncated cone. The side face of the circular truncated cone is provided with the keyway. The bottom parts of the key pin and keyway are both provided with screw holes. The screw holes of the key pins penetrate through the key pins. Bolts penetrate through the screw holes so that the key pin is fixedly connected with the keyway. The external surface of the key pin is provided with scales. The keyway is added on the side face of the circular truncated cone so that in precision measurement of inner holes of impellers, precision measurement can be carried out on depths of inner-hole pin grooves simultaneously through the keyway and the key pin, thus not only the match degree of the keyway and the key pin can be ensured but also the labor frequency can be reduced and the testing efficiency of the impellers is improved.
Description
Technical field
The utility model relates to impeller subtest tool field, is specifically related to the taper hole keyseat gauge tool that a kind of impeller that is applied to industrial large-sized water pump is tested.
Background technology
In machine-building, the suitable trouble of the measurement of taper hole keyway degree of accuracy, refer more particularly to the industry that ask for something precision is very high, as the test of industrial large-sized water pump.In the process that industrial large-sized water pump is tested, the break-in degree of impeller and motor shaft is higher, more favourable to the serviceable life of water pump.For this reason, before the product impeller dispatches from the factory, we have carried out reliability testing for the coupling part of impeller, traditional method: endoporus and endoporus cotter way for impeller are made respectively corresponding tool, by craft, the coupling part of impeller is tested, although the result of test can guarantee the precision of taper hole and the precision of keyway like this, when keyway and taper hole are used simultaneously, can't guarantee that the quality of fit of two reaches the requirement of product.Simultaneously, the identical product impeller is carried out to twice test, also increased greatly artificial finished product.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of taper hole keyseat gauge, its objective is the measurement jig that improves keyway and taper hole matching degree on a kind of basis guaranteeing taper hole precision and keyway precision is provided, and also can reduce cost of labor simultaneously.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of taper hole keyseat gauge, it is characterized in that, comprise round platform, right cylinder, key pin and keyway, described right cylinder is fixedly installed on described round platform bottom surface, described frustum cone side is provided with described keyway, and described key pin and described keyway bottom are provided with screw, and described screw is through described key pin, described key pin passes described screw by bolt and is fixedly connected in described keyway, and described key pin outside surface is provided with scale.
Preferably, the axle of described right cylinder axle center and described round platform is located along the same line.
Preferably, described keyway, through described round platform side two ends, is communicated with described round platform bottom surface and described round platform upper bottom surface respectively.
Preferably, the screw on described key pin and described keyway bottom is three, is distributed in rear and front end and the centre position of described key pin and described keyway bottom.
Preferably, the longitudinal section of described keyway and described key pin is isosceles trapezoidal structure, and the upper base angle of the waist of described isosceles trapezoidal structure and described isosceles trapezoidal structure is 83 degree.
Pass through technique scheme, the beneficial effect that the utility model is obtained is: by frustum cone side, adding keyway, make when the impeller endoporus is carried out to accuracy test, just can carry out accuracy test to the endoporus cotter way degree of depth by keyway and key pin simultaneously, the matching degree that can either guarantee like this keyway and key pin can reduce the work number of times again, improves the detection efficiency of impeller.
