Description
Technical field
The utility model relates to a kind of dynamic balancing measurement device that is used for the blind hole compression impellor.
Background technology
At present, in the manufacture process of compression impellor, must carry out dynamic balancing measurement to compression impellor, existing proving installation is had the mandrel that supports shelves by two ends, and belt pulley on the mandrel and the motor that is in transmission connection of pulley belt, dynamic balancing machine is formed, this device can only carry out the compression impellor that has through hole: the compression impellor that will have through hole earlier is enclosed within on the transient equilibrium mandrel, pass through end cap, with screw compression impellor is compressed, support shelves with the mandrel two ends are supported on whole compression impellor and mandrel on the dynamic balancing machine again, on belt pulley, put belt, starter motor, make compression impellor reach certain speed by belt gear, the unbalancing value of compression impellor is reflected on the display screen of dynamic balancing machine, according to this amount of unbalance compressor impeller is gone heavily to handle to reach dynamically balanced accuracy requirement; And for the blind hole compression impellor, this compression impellor can't put mandrel owing to there is not through hole at all, and the two ends of compression impellor do not have support zone yet, can not adopt above-mentioned proving installation to move flat test.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to use, measure the dynamic balancing measurement device that is used for the blind hole compression impellor accurately.
The purpose of this utility model is achieved in that a kind of dynamic balancing measurement device that is used for the blind hole compression impellor, it comprises: base, be arranged at intervals at two stands on the base, place the mandrel on the two stands, it is characterized in that: the front end of described mandrel has a thread segment, after this thread segment is a positioning section, what be close to positioning section is the shaft shoulder, after the shaft shoulder two support shelves, supporting between the shelves described two is belt pulley, they are a single piece, and two of described mandrel supports shelves and places on described two bracing frames; Be provided with an auxiliary support frame with the obverse described base of described mandrel, be equipped with one on the table bar of this auxiliary support frame and support steel ball.
Be with packing ring on the thread end of the thread segment of above-mentioned mandrel.
The thickness of above-mentioned packing ring be on the thread segment of described mandrel thread pitch 1/2nd.
Be provided with belt holder between the above-mentioned two stands, the belt on this belt holder is placed on the described belt pulley and with described motor and is connected.
Two bracing frames that described two bracing frames of the utility model and described two support the shelves touching position are provided with bearing.
The course of work of the present utility model is: the first step, adjust the spacing of two stands on the base according to the spacing of mandrel two support shelves, the thread segment of mandrel is carried on the back arc end screw with blind hole compression impellor to be measured to be threaded back (not adding packing ring), on the mandrel two supported shelves to be placed on the two stands respectively, the mandrel belt pulley is put belt on the belt holder, the support steel ball of auxiliary support frame upper meter rod front end and the tapered hole at blind hole compression impellor inlet end center are offseted; Second step, with switch board that this proving installation is connected on configure this dynamic balancing measurement mode be that biasing cantilever two sides is gone heavily, configure the unbalancing value of blind hole compression impellor designing requirement, and the rotating speed of this balance test, starter motor, the blind hole compression impellor is high speed rotating under the driving of motor, auxiliary support frame has been avoided the axial float of compression impellor, when the compression impellor rotating speed reaches setting value, unbalancing value passes to control system by sensor, and notes the size and Orientation of moving uneven amount; The 3rd step, the blind hole compression impellor is unloaded from mandrel, and at its thread end cover upper gasket, the thickness of this packing ring is 1/2nd of mandrel and compression impellor connecting thread pitch, purpose is to allow compression impellor rotate 180 degree on mandrel, starter motor once more after compression impellor installed, when the compression impellor rotating speed reaches setting value, unbalancing value passes to control system by sensor, and note the size and Orientation (unbalancing value of this moment and orientation are that the vector of twice unbalancing value and direction is synthetic) of moving uneven amount, can go heavy and counterweight to blind hole compression impellor two ends assigned position according to this unbalancing value and orientation, it is met design requirement.
The utility model is simple in structure, assembling is easy, easy to operate, measuring accuracy is high, is widely used in the dynamic balancing measurement of blind hole compression impellor.
