The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of flexible adaptive mechanism of sander, comprise main shaft 100 and the handle of a knife 200 that is arranged at main shaft 100 front ends, main shaft 100 is outer is provided with bracing frame 300 by bolt 110 adapter sleeves, bracing frame 300 comprises the cylindrical sleeve 310 be set on main shaft 100 outer walls and the projection 320 that is arranged at cylindrical sleeve 310 1 ends, the outer supporting seat 400 that also is arranged with of main shaft 100 that projection 320 sides are other, supporting seat 400 comprises being set in the outer annulus cake of main shaft 100 410 and being connected in annulus cake 410 outer rings and extends and cover the supporting seat cylindrical sleeve 420 of the projection 320 of bracing frame 300 to the direction of bracing frame 300, there is gap between the annulus cake 410 of supporting seat 400 and main shaft 100, on supporting seat cylindrical sleeve 420 inwalls, the position corresponding with bracing frame 300 protruding 320 is arc, the periphery of projection 320 is also arc, be provided with pneumatic cylinder 500 in supporting seat 400, be provided with 8 groups of piston rod straight pins 510 and piston straight pin 520 in pneumatic cylinder 500, piston rod straight pin 510 ejects towards projection 320 directions of bracing frame 300.Piston rod straight pin 510 plays stressed effect; Piston straight pin 520 plays sealing function.
Referring to Fig. 2, in the utility model, be provided with pneumatic cylinder 500 in supporting seat 400, and be provided with an air inlet hydraulic quick coupler 530, UNICOM between 8 groups of piston straight pins, the 520 air inlet cavitys of air inlet hydraulic quick coupler 530 and pneumatic cylinder 500, by being ventilated to pneumatic cylinder 500 from air inlet hydraulic quick coupler 530.
Be arranged with O type circle 540 between pneumatic cylinder 500 and annulus cake 410, the effect of O type circle 540 is the sealings that guarantee the air inlet cavity.
The junction outer setting of supporting seat cylindrical sleeve 420 and the projection 320 of bracing frame 300 has and prevents that bracing frame 300 from skidding off the baffle ring 600 of supporting seat 400, baffle ring 600 be connected on supporting seat cylindrical sleeve 420 and and the cylindrical sleeve 310 of bracing frame 300 between gapped.
Also be provided with sealing ring 610 between cylindrical sleeve 310 outer walls of baffle ring 600 and bracing frame 300, sealing ring 610 effects are the dustproof and auxiliary main shafts 100 of installing.
Also be connected with on supporting seat 400 and cover the other end dust cover 700 that main shaft 100 is provided with handle of a knife 200, dust cover 700 can prevent dust access mechanism inside.
The other end that main shaft 100 is provided with handle of a knife 200 is provided with range finding inductor 120, be provided with reflecting plate 710 on dust cover 700, range finding inductor 120 and reflecting plate 710 on same straight line, range finding inductor 120 can measure and reflecting plate 710 between distance.
Referring to Fig. 3, by air inlet, pneumatic cylinder 500 is ventilated, piston rod straight pin 510 is all ejected, piston rod straight pin 510 withstands on the projection of bracing frame 300 320 on the end face of baffle ring 600.Main shaft 100 drives handle of a knife 200 High Rotation Speeds, foundry goods is polished, when foundry goods body or burr are larger, power tool is increased by radial load, because bracing frame 300 and main shaft 100 are assembled together, during the stressed confining force over setting, again because have gap between the annulus cake 410 of supporting seat 400 and main shaft 100, on supporting seat cylindrical sleeve 420 inwalls, the position corresponding with bracing frame 300 protruding 320 is arc, the periphery of projection 320 is also arc, so bracing frame 300 can rotate around the contact point with baffle ring 600, until the ejecting force of the external force that main shaft 100 is subject to and piston rod straight pin 510 reaches balance.When the suffered external force of main shaft 100 is less than the confining force of setting, poised state when bracing frame 300 can return to initial ventilation.In mechanism, steel ball 321 plays the effect of restriction bracing frame 300 axial-rotations.
Referring to Fig. 4, main shaft 100 axially loadeds surpass the confining force of setting, when main shaft 100 will axial dipole field occur, until the ejecting force of the external force that main shaft 100 is subject to and piston rod straight pin 510 reaches balance.When the suffered external force of main shaft 100 is less than the confining force of setting, poised state when bracing frame 300 can return to initial ventilation.
Referring to Fig. 3, Fig. 4, radial deflection and axial dipole field occur in main shaft 100, range finding inductor 120 is radial deflection and axial dipole field thereupon, by the cooperation range finding inductor 120 perception side-play amounts in real time of reflecting plate 710, and sends offset information to control system.Can set two pre-set threshold value in control system, when if displacement surpasses the first predetermined threshold value, meaning runs into larger accessible burr, the gait of march that control system is controlled main shaft 100 is automatically turned down a certain setting value and is carried out the low speed polishing, carrying out along with polishing, when the displacement detected is less than the first predetermined threshold value, control system control main shaft 100 automatically switches to normal gait of march and is polished.Like this, just can eliminate the impact brought not of uniform size of foundry goods self size and burr, guarantee the uniformity of polishing effect.If run into very large burr or surpass the foundry goods of tolerance; exceed normal polishing scope; at this moment the side-play amount that the inductor 120 of finding range detects is greater than the second pre-set threshold value (the second predetermined threshold value is greater than the first predetermined threshold value); control system hard stop now; polishing work stops; simultaneity factor is reported to the police, and waits for artificial treatment.Protect well in this way whole machine and instrument, avoid the destruction of improper factor to whole machine and instrument.
The beneficial effects of the utility model are: by keeping constant air pressure, guarantee constant polishing contact force, the size of flexible adaptive mechanism confining force is arranged according to the material of workpiece and the cutting parameter of cutter, the flexibility of flexible adaptive mechanism can auto-compensation workpiece self deviation, can adjust in real time gait of march in conjunction with offset detection and reponse system robot, can effectively evade large overlap cutter is caused and damages and guarantee stable polishing quality.Flexible adaptive mechanism can reduce the teaching difficulty of robot motion's track, significantly improves the operating efficiency of enforcement.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
