Figure.
Fig. 4 is the dynamometry schematic diagram of the grinding pressure of the utility model.
Fig. 5 is specific embodiment of the present utility model flow chart.
Specific implementation mode
Such as Fig. 1, the utility model is related to the primary structure of sluice valve grinder be：Fixed frame 1 by first rotating shaft 3 with
Movable machine frame 2 connects, and fixed frame 1 plays the role of the entire grinder of support.Movable machine frame 2 is that transverse arm is fixedly connected with straight-arm
At L-shaped crank arm.Grinding power drive mechanism includes abrasive power adjustment motor 4 and ball screw assembly, and it is general that abrasive power, which adjusts motor 4,
Logical electric rotating machine.Abrasive power adjusts motor 4 and is mounted on fixed frame 1 by shaft, and the output end that abrasive power adjusts motor 4 connects
The leading screw 5 of ball screw assembly, the nut of ball screw assembly, and the lower end of straight-arm is connect to connect by the second shaft 12.Abrasive power adjusts
The installation direction of motor 4 and ball-screw 5 is R axis directions.Force snesor 6 is installed on abrasive power adjustment motor 4 and the motor cabinet
Between clamping plate and rubber sheet gasket among.Mechanics sensor can experience the deformation of rubber sheet gasket to which resistance changes.Power
The controller that the inductive signal of sensor 6 adjusts motor 4 with abrasive power is connect, and controller is for controlling abrasive power adjustment motor 4
Driving output.
Drive link 7 is fixedly connected with above transverse arm, one end of drive link 7 is fixedly connected with grinding power motor 8, other end connection
Abrasive disk 9, several of abrasive disk 9 are ground on arms equipped with sand paper 10, and object 11 to be ground is ground by sand paper 10.Drive link 7,
Grind power motor 8, the composition grinding actuating unit of abrasive disk 9.
Abrasive power adjusts motor 4 and provides torque, rotates ball-screw 5 connected to it.Lead screw 5 is rotated, and rolling is driven
Nut on ballscrew 5 is for linear motion, and nut drives movable machine frame 2, and 3 rotation, movable machine frame 2 drive entire grinding around the shaft
Actuating unit is rotated, to adjust the pressure that abrasive disk treats grinding object.
It is that above-mentioned abrasive power is adjusted to the structure straight line of motor and ball-screw as a more optimized technical solution
Motor replaces the adjusting, it can be achieved that more accurate and faster speed.Disadvantage is that the cost of linear motor compared with electric rotating machine with
Ball-screw pattern wants high.
When grinding after a certain period of time, the surface of object to be ground is ground, generated between abrasive disk and grinding surface it is small between
Gap.Obviously, the pressure between mill and grinding surface will be reduced at this time.To ensure to keep the conjunction of setting between mill and grinding surface
Suitable pressure needs driving grinding actuating unit to be rotated to object direction to be ground.
As shown in Fig. 2, the steering driving mechanism that movable machine frame 2, abrasive power adjustment motor 4, ball-screw 5 form is in water
Level state.As shown in figure 3, driving grinding actuating unit is rotated around shaft, it is close to abradant surface.
Fig. 4 describes the principle of force sensor measuring power.Object to be ground gives mill upward abrasive power f, and sensor connects
Receive detection power f '.It then grinds object and gives the upward abrasive power f of mill and be：
F=(d1/d2) * f '
When grinding gate valve, starts abrasive power first and adjust motor 4, abrasive power adjusts motor 4 and provides torque, and rotation connects with it
The ball-screw 5 connect.Lead screw 5 is rotated, and drives the nut on ball-screw 5 for linear motion, and nut drives movable machine frame 2
3 rotation around the shaft, movable machine frame 2 drive entire grinding actuating unit to be rotated, abrasive disk 9 are made to be tightly attached to object 11 to be ground
On.Then, start grinding power motor 8, grinding power motor 8 provides torque to drive link 7, so that drive link 7 is rotated, drive is ground
Mill 9 rotates, and treats grinding object and is ground.In process of lapping, force snesor 6 monitors abrasive disk and object to be ground in real time
Grinding surface between pressure.When force snesor 6 receives pressure signal, pressure signal is converted into electric signal, feeds back to and grinds
It grinds power and adjusts electric machine controller.The controller of abrasive power adjustment motor 4 receives the electric signal that force snesor 6 is sent in real time, passes through
Pid algorithm judges the signal that force snesor 6 is sent and is filtered that, to exclude the interference that fluctuation generates, controller is to pressure
Power is analyzed, and changes the driving current generated to abrasive power adjustment motor according to analysis result, and abrasive power is made to adjust motor
Forward or reverse, to keep grinding pressure to be in stable state.
Such as Fig. 5, when grinding beginning, it is f0 to set required abrasive power, and the power detected in real time is f.As the power f measured
>When f0, illustrate the abrasive power applied higher than expection, controller driving abrasive power adjustment motor rotates in the forward direction, and passes through ball-screw
Movable machine frame is driven to rotate counterclockwise, movable machine frame drives entire grinding actuating unit to rotate counterclockwise, and abradant surface is applied in reduction
The pressure added；As the power f> measured;When f0, illustrate the abrasive power applied less than expection, controller drives abrasive power adjustment motor anti-
To rotation, movable machine frame is driven to rotate clockwise by ball-screw, movable machine frame drives entire grinding actuating unit clockwise
Rotation increases the pressure applied to abradant surface.When determining that grinding has been completed, reinforcing motor no longer applies abradant surface permanent
Power.
It should be pointed out that for the utility model through absolutely proving, can also have a variety of transformation and the implementation of remodeling
Scheme, it is not limited to the specific embodiment of the above embodiment.Above-described embodiment as just the utility model explanation, and
It is not limitations of the present invention.In short, the scope of protection of the utility model should be including those for ordinary skill
It obviously converts or substitutes and retrofit for personnel.
