Connecting, abrasive disk is positioned at runner plate and supports above seat.
In the present embodiment, described main spindle box includes casing, is vertically arranged with main shaft in casing, and main shaft is through being set in main shaft
On bearing be fixed in casing, main shaft bottom is provided with turbine, worm shaft, and main shaft is main spindle box output shaft, and worm shaft is main
Axle box power shaft, worm shaft is provided with the worm screw engaged with turbine, and worm screw is connected transmission, running through on main shaft with Power Component
Main spindle box upper side, and be connected with pivoted arm.
In the present embodiment, described pivoted arm includes intermediate sleeve, intermediate sleeve week side be symmetrically arranged with bull stick, for compatibility not
Process with the runner plate of size, described bull stick be provided with some installation sleeves from inside to outside, sleeve is installed and is used for abrasive disk is installed,
Pivoted arm is set on main shaft through intermediate sleeve and is connected with main shaft key, and intermediate sleeve top cover is provided with pressing plate, pressing plate and main shaft warp
Bolt is connected.
In the present embodiment, described abrasive disk includes that mandrel, mandrel top are set in installation sleeve, and mandrel lower end is arranged
Grinding disk body, grinding disk body warp beam is had to hold and be rotationally connected with mandrel.
In the present embodiment, mandrel lower end is provided with bearing block, and bearing is arranged on bearing block and grinds between disk body, bearing
Seat is spirally connected with grinding disk body.
In the present embodiment, intermediate sleeve being provided with the clamping screw locking mandrel, clamping screw one end sets
It is equipped with handle, the other end and mandrel joint.
In the present embodiment, described runner plate supports seat and includes supporting seat, supports and is vertically arranged at supporting screw on seat, supports
Screw head is provided with a bracer, and supporting screw is spirally connected with supporting seat, supports seat bottom portion and is spirally connected with soleplate, for compatible different chis
Very little runner plate processing, soleplate does not the most have some groups for installing the screw supporting seat.
In the present embodiment, supporting seat lateral surface and be provided with baffle plate, baffle plate is provided with alignment device, alignment device is for setting
Putting the centering screw rod on baffle plate top, centering screw rod is spirally connected with baffle plate, and centering screw rod one end is run through baffle plate and is provided with and supports

Footpath is typically within 1.8m.
In the present embodiment, abrasive disk is wrapped with and contaminates the sub-cloth of Buddhist nun having grinding agent.
During the work of common grinding machine, owing to the grinding rate of the different-diameter point on annulus minute surface is different, and the grinding of each point
Mill track repeats, so grinding resection and grinding effect at different-diameter are variant on minute surface, if excess is ground (removes mirror
Face cut or burn trace etc. and need) then can expand the flatness error of minute surface.
Compared with common grinding machine, this runner plate grinder lap diameter, more than the width of runner plate anchor ring, grinds owner
Axle is stirred abrasive disk by the mandrel being fixed on pivoted arm and is circled along runner plate face, the friction of different-diameter point on abrasive disk
The resultant moment of moment is ordered about abrasive disk and is made uniform rotation around mandrel again.So, on minute surface, the grinding rate of each point is the most equal, and respectively
The grinding track of point does not repeats, and in process of lapping, the roughness of minute surface and flatness error all can reduce.
| Lapping mode | Duration (my god) | Artificial work day (my god) | Expense (first) | Minute surface roughness |
| Send maker | 7-9 | 14 | 20000-30000 | ＜ Ra0.2 |
| Artificial mechanical | 7 | 70 | 8000-10000 | Ra0.2 |
| Common grinding machine | 6-7 | 21 | 5000-6000 | Ra0.2 |
| Runner plate grinder | 1 | 4 | 800-1000 | ＜ Ra0.2 |
This runner plate grinder, and prior art leading indicator such as following table:
During use, first according to runner plate size to be processed, the installation site of regulation runner plate support seat comparative basis plate, subsequently,
Runner plate is placed on runner plate support on seat, then pivoted arm is installed, suitably pacifies according to runner plate size Selection to be processed subsequently
Sleeved installation grinding assembly, then by the relative position of supporting screw regulation runner plate with centering screw rod regulation runner plate so that
Runner plate anchor ring and abrasive disk joint, subsequent start-up motor, pivoted arm rotates around main-shaft axis, stirs the abrasive disk circle along runner plate
Anchor ring circles, and is ground the minute surface of runner plate, after roughness reaches requirement, closes motor, parcel leaching on abrasive disk
Being infected with the sub-cloth of Buddhist nun of grinding agent, subsequent start-up motor, pivoted arm rotates around main-shaft axis, stirs the abrasive disk anchor ring work along runner plate
Circular motion, is processed by shot blasting the minute surface of runner plate.
On be classified as preferred embodiment, the object, technical solutions and advantages of the present invention are further described, institute
It should be understood that and the foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all the present invention's
Within spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
