Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, clamping device floats, comprise the rotating main shaft 6 that is in transmission connection with motor 9, be provided with bearing 14 between main shaft 6 and the frame 12, main shaft 6 for hollow structure and in establish pull bar 5, the upper end of pull bar 5 is provided with elastic conical drogue 8, reserve the clamped location of workpiece between elastic conical drogue 8 and main shaft 6 upper ends, establish counterbore in the lower end of main shaft 6 and dish spring 4 is set, pull bar 5 is set in the dish spring 4, the lower end of pull bar 5 is provided with the card 13 of anti-dish spring 4 slippages, and the lower end of main shaft 6 is provided with main shaft annulus 11; The below of main shaft 6 is provided with power cylinder 1, be provided with piston 2 in the power cylinder 1, the cavity of resorption of power cylinder 1 is communicated with the pressure fluid control appliance, the upper end of piston 2 is corresponding with pull bar 5 lower end in the vertical directions, be provided with back-moving spring 3 between power cylinder 1 and frame 12 bottoms, power cylinder 1 upside is provided with trip 10, and the upper end of trip 10 and main shaft annulus 11 are equipped with.
Measurement state lower main axis 6 is at high speed rotary, so when the state of measurement, workpiece 7 must be stepped up, can not contact with main shaft 6 but step up device, therefore be designed to the clamping device that floats, this device has automatic clamping and the function of unclamping, and can satisfy the balance needs again simultaneously.
Operation principle is as follows: when piston 2 in the power cylinder 1 is in when the next, the clamping device trip 10 that floats separates with main shaft annulus 11, and hollow main shaft 6 is equipped with one group of dish spring 4, by pull bar 5, tension elastic conical drogue 8 utilizes the frictional force of elastic conical drogue 8 that workpiece 7 and main shaft 6 are connected as a single entity.Starter motor 9 just can carry out unbalance dynamic and measure this moment.
The utility model promptly can be used on the automatic balancing machine, also can apply on the automatically processing device of other dish series products.
