Specific embodiment
The simple operations that the present invention passes through " once leaning on, two tops, three pressures " can be rapidly completed positioning and the locking of flat board group.
As shown in figure 1, three faces that " leans on " is flat board group rest on main location-plate, left locating piece and lower locating piece respectively
On；" two tops " is to hold out against spiral to hold out against flat board group from right side；" three pressures " is to rotatably compress knob to make to hold down assembly from front side supports
Flat board group.In order to ensure the positioning precision of frock, first each locating piece is installed on positioning support, then repaiies the positioning cutting locating piece
Face reaches the form and position tolerance precision specified.The use of disc spring ensure that compression rhampotheca can slide up and down in stationary bushing, reaches
To the purpose compressing or loosening flat board group.
Specifically, the quick-gripping device of this heavy caliber ultra-thin panel includes positioning support, positioning group and compression group.Fixed
Position bearing is to be connected by bolt by positioning seat base plate, main location-plate and reinforcement gusset, L-shaped.Flat board group (band inside casing) is hanged
Hang on positioning support, and only lean against on main location-plate.
Positioning component by left locating piece, lower locating piece, right fixed block and holds out against spiral and forms.Left locating piece and lower locating piece
Ensure being accurately positioned of flat board as positioning datum in vertical plane, hold out against in the screw that spiral is arranged on right fixed block, and from the right side
Side holds out against inside casing through right fixed block.Hold out against screw selecting nylon 1010.
Hold down assembly and be distributed in the corner of main location-plate, by screw rod of usheing to seat, stationary bushing, compression rhampotheca, compression knob and
Disc spring group forms.There is screw in the middle of compression knob, be arranged on and usher to seat on screw rod.Disc spring group selection outer diameter D=8mm disc spring, every group
20, it is through and ushers to seat on screw rod.The quantity adjusting every group of disc spring can be with the regulated quantity size of effective control compression group.Rotatably compress
Knob, the disc spring group in compression compression rhampotheca, promote compression rhampotheca to slide in stationary bushing, until rhampotheca is in front is pushed down
Four angles of frame.
It is, in principle, that the present invention is built for flat board orientation adjustment by design measurement seat group locating piece and measurement seat group rotating shaft
Vertical benchmark rotary shaft.Measurement seat group locating piece is fixed on optical table, and is located in the groove below positioning seat base plate.Measurement
Seat group rotating shaft is arranged on measurement seat group locating piece, tangent with main location-plate also cross the via on positioning seat base plate.Debugging
During light path, whole measurement and positioning frock group passes through plate center all the time around measurement seat group rotating shaft rotation, the center line of rotating shaft.
To sum up, the present invention realizes the orientation adjustment of flat board group by positioning rotating shaft, is ensured and rotating shaft cooperation by processing
Installing hole vertical precision, also to ensure that rotating shaft upper end is tangent with main location-plate, then according to thickness surveyed by flat board simultaneously
Twice is processing rotating shaft upper end external diameter.So, rotating shaft when whole positioning component rotates remains stationary as, and shaft centerline is all the time
By plate center, thus realizing high-precision attitude adjustment.
