Therefore, in the existing quartzy mechanical processing process, drive motors is in the frequent starting operating state, not only the impact to electrical network is very big, energy consumption is also very big simultaneously, average 20～30% the energy consumption that increases, also very big to the damage of quartzy machinery, drive motors bearing failure and grinding spindle splined shaft failure phenomenon often appear.
Summary of the invention
The utility model provides a kind of automatic on-off braking device of quartzy machinery, make quartzy machinery in the process of changing grinding tool, need not drive motors is stopped, avoid the phenomenon that allows the drive motors frequent starting, stop, thereby improved the operating efficiency and the reliability of quartzy plant equipment, the working life that cuts down the consumption of energy and prolong drive motors greatly.
A kind of automatic on-off braking device of quartzy machinery comprises drive motors and the belt pulley that is installed on the drive motors.
The coaxial spacer shell of suit one on the output shaft of described drive motors; The first electromagnetic clutch coil, first clutch friction plate, second clutch friction plate and belt pulley are installed on the described spacer shell successively; The described first electromagnetic clutch coil is connected with described spacer shell by at least one bearing; Described second clutch friction plate is fixed on the described belt pulley; Described belt pulley is connected with described spacer shell by at least two bearings; Described first clutch friction plate matches with the described first electromagnetic clutch coil, constitutes first electromagnetic clutch device;
The place ahead of the output shaft of described drive motors is provided with a fixed support, and described fixed support is provided with coaxial and have the fixed axis of spacing mutually with the output shaft of described drive motors; The brake strip and the second electromagnetic clutch coil are installed on the described fixed axis successively; The described second electromagnetic clutch coil stationary is on described fixed support; Described brake strip matches with the described second electromagnetic clutch coil, constitutes second electromagnetic clutch device.
Wherein, described second clutch friction plate by screw on described belt pulley; Described spacer shell is sleeved on the output shaft of described drive motors by driving key; Described first clutch friction plate is sleeved on the described spacer shell by first retainingf key; Described brake strip is sleeved on the described fixed axis by second retainingf key.
Operation principle of the present utility model is: drive motors is in running order all the time, and the power of drive motors is delivered on the belt pulley by first electromagnetic clutch device on the spacer shell; When braking, automatic and the belt pulley disengagement of first electromagnetic clutch device on the spacer shell, second electromagnetic clutch device on the fixed axis is worked automatically, utilize brake strip that belt pulley is braked, need not frequently stop to start drive motors when so just can be implemented in the replacing grinding tool, reach the purpose that cuts down the consumption of energy.Therefore, the utility model is finished driving and braking to belt pulley by the combination of first electromagnetic clutch device and second electromagnetic clutch device, and drive motors then is in normal operating state all the time.To the control of first clutch friction plate and brake strip is that power on/off by the electromagnet on the first electromagnetic clutch coil and the second electromagnetic clutch coil realizes that the magnet switching electricity is then realized controlling by peripheral control unit.
With respect to prior art, the utlity model has following beneficial technical effects is: the utility model is by installing arrangement of clutch on the output shaft of drive motors, utilize electromagnetic clutch device to drive the belt pulley that is connected with grinding attachment with braking, make and drive motors need not be stopped when needing to change grinding tool in the course of the work, drive motors is in running order all the time, the bistrique braking is adopting the mode of friction plate to brake on the level at a high speed, thereby the frequent starting of drive motors when having avoided changing grinding tool, the phenomenon that stops to reach energy savings and the effect that prolongs the drive motors working life.Compared with prior art, the utility model device has improved mechanical operating efficiency greatly, alleviates operator's labour intensity, and energy savings is about 15～25%, has prolonged the working life of drive motors, and has improved mechanical reliability.
