Description
Technical field
The present invention is applied to grinding field in machined, is mainly applicable to utilize polished machine with the test specimen of small batch, to carry out high-precision grinding and buffing field to experiment.
Background technology
Numerous, relate in the mach occasion of material surface high accuracy, the application of polished machine is in occupation of consequence.Particularly, under laboratory condition, often the particularity polished machine supplier due to test specimen cannot provide general clamping device completely.For some very little test specimens of length on vertical grinding and polishing in-plane, direct hand-held grinding and polishing difficulty is very large, and polishing even can damage by force.Under this background, invented a kind of force feedback self adaptation polished machine test specimen clamping device.
Summary of the invention
It is a kind of for coordinating polished machine to carry out the device of mach clamping test pieces that patent object of the present invention is to provide, and when with polished machine polishing test specimen, this device can regulate the height of test specimen in real time by force measurement is realized to feedback, to guarantee grinding and polishing quality.
A force feedback self adaptation polished machine test specimen clamping device, is characterized in that: comprise 4 permanent magnet Attraction blocks, 4 height regulate thread bush, and 4 height regulate threaded rod, 2 crossbeams, 2 bearings, roll adjustment beam, 2 roll adjustment beam screw threads are embraced ring, pin, roll adjustment connecting rod, 2 lift beams are embraced ring, controller, shaft coupling, headstock, distance-adjusting motor, lift beam, bolt, nut, clamp, power sensor, crossbeam level indicator;
Wherein 4 permanent magnet Attraction blocks are adsorbed on polished machine surface, be arranged symmetrically in each 1 height that is all rigidly connected above permanent magnet blocks 1 of polished machine working rotary table four positions around and regulate thread bush, highly regulate the upper part of thread bush be processed with internal thread highly regulate thread bush above have and highly regulate threaded rod, highly regulate one end of threaded rod to be processed with external screw thread, and highly regulate screwing into of threaded rod highly to regulate symmetrical placement of 2 crossbeams of internal thread of thread bush, by a pair of height, regulated respectively the dead eye that is processed with of threaded rod supporting traverse middle part level, the two ends that bearing is embedded in the interior roll adjustment beam of dead eye of crossbeam are spindle nose, middle part is symmetrily processed with two sections of reverse threads, roll adjustment beam passes crossbeam by bearing, and by bearing, can freely rotate 2 roll adjustment beam screw threads embraces ring and is threaded connection to be respectively symmetrically placed in and on two sections of reverse threads of roll adjustment beam, in one end of roll adjustment beam, by shaft coupling, is connected with distance-adjusting motor shaft coupling and distance-adjusting motor is all placed in the side that headstock internal motivation case is fixed on crossbeam, controller is fixed on headstock top, controller controls to the rotating speed of distance-adjusting motor the below that lift beam is placed in roll adjustment beam, 2 lift beams of the two axis keeping parallelism are embraced symmetrical being enclosed within on lift beam of ring and in the roll adjustment beam screw thread of homonymy, are embraced ring and lift beam and embrace to encircle and be connected by roll adjustment connecting rod, roll adjustment connecting rod is embraced ring with roll adjustment beam screw thread respectively, lift beam is embraced ring, and by pin, to connect clamp be the cuboid that is processed with penetrating screwed hole, fixed block be wherein fixed on lift beam below, when movable block keeps freely needing clamping test pieces, movable block and the fixed block of clamp pass through bolt, nut connects to clamp the surface that test specimen power sensor is placed in a vertical direction of clamp, power sensor and controller carry out signal transmission crossbeam level indicator and are embedded in the upper surface of crossbeam.
Basic functional principle is for when test specimen contacts with polished machine working rotary table, dial rotation direction tangentially can produce frictional force to test specimen, this frictional force can cause the distortion of clamp, this distortion can detect and send to controller 11 by power sensor 18.According to control program, have two kinds of situations, situation one is that the power detecting is less than or equal to setting value, and this setting value, for starting the front manually value of input of grinding and polishing, is the value that is applicable to a grinding tangential force of current test specimen, and grinding and polishing is carried out normally in this case; Situation two is that the power detecting is greater than setting value, and it is undesired that now grinding and polishing is carried out, and controller 11 can be controlled the height that distance-adjusting motors 14 regulate lift beams 15, until reach the state of situation one.Under the condition of situation one, controller 11 can judge the size of current grinding thickness and setting value, current grinding thickness is the total height that after beginning grinding and polishing, lift beam 15 declines, setting value is for starting a value of the front artificial input of grinding and polishing, if current grinding thickness is less than setting value, controller 11 sends command adapted thereto to distance-adjusting motor 14, distance-adjusting motor 14 rotates, drive roll adjustment beam 6 synchronously to rotate, because 6 two sections of screw threads of roll adjustment beam are reverse, can make two roll adjustment beam screw threads embrace ring 7 respectively to two side shiftings, and translational speed is equal, has guaranteed that lift beam 15 levels decline; If current grinding thickness is equal to or greater than setting value, controller 11 sends command adapted thereto to distance-adjusting motor 14, and it is rotated backward, and improves lift beam 15, make it turn back to setting height after distance-adjusting motor 14 stop operating.Completed the whole process that force feedback regulates test specimen grinding thickness and feed speed automatically.
