Summary of the invention
The object of the invention is exactly in order to make up the defect of prior art, provide a kind of can on-line measurement and control measurement mechanism and the method for amount of grinding.
The present invention is achieved by the following technical solutions:
A kind of mechanical type face contact amount of grinding on-line measurement device, it is characterized in that: described device is by base pad, screw, base, feeding screw thread, calibration nut, screw rod, locking nut, top nut, counterweight, dry submeter, amesdial mount pad, holding screw and carrying disk form, wherein base top is provided with amesdial mount pad, below is provided with base pad, there is ladder hole at base middle part, in hole, pass the screw rod coordinating with interporal lacuna, the upper and lower two ends of screw rod respectively with top nut, carrying disk thread connection, screw rod middle part cover has the feeding screw thread with its matched in clearance, feeding screw thread from top to bottom successively with locking nut, calibration nut thread connects, feeding screw thread and calibration nut are arranged on respectively in the shoulder hole and draw-in groove of base, amesdial is arranged on amesdial mount pad, and locate with holding screw.
Described amesdial has two, and symmetry is arranged on amesdial mount pad.
One in symmetrical two amesdials installing plays a part balance, the heavy burden on base is evenly distributed.
Described base pad is made with high-abrasive material, and bottom is circumferentially uniform-distribution with the position of three depressions, and screw is installed, and base pad is connected with base, although grind base pad, is also being worn, and its wear extent is negligible.
On described calibration nut, have graduation mark, be divided into 200 little lattice, calibration nut turns little lattice, makes feeding screw thread move axially 0.005mm, and calibration nut revolves and turns around, and makes feeding screw thread move axially 1mm.
A face contact amount of grinding On-line Measuring Method, comprises the following steps:
A. test specimen is sticked in the middle of carrying disk lower surface;
B. device is placed on smooth horizontal plane, rotary index nut, makes its light base of pressing, and writes down the now calibration nut zero right position base of groove;
C. according to the size of predetermined amount of grinding, the certain number of turns of reversion calibration nut, locks with locking nut;
D. amesdial is arranged on the amesdial mount pad of device, adjusts amesdial, make the contact compression carrying disk of amesdial, lock-screw, writes down the now reading of amesdial;
E. device is put on grinder and is ground, from amesdial, can read in real time the size of amount of grinding, when amount of grinding reaches predetermined value, nut lower surface, top stops the upper surface laminating with feeding screw thread to decline, the grinding of workpiece stops, thereby completes grinding.
Rotary index nut is gently pressed base, makes feeding threaded upper end face and the laminating of nut lower surface, top.
Calibration nut reverses after a fixing turn, and rotational lock nut makes locking nut compress calibration nut, and calibration nut is fixed to position, and the distance between now feeding threaded upper end face and nut lower surface, top just equals the size of predetermined amount of grinding.
Along with the carrying out of grinding, specimen thickness constantly reduces, and makes carrying disk, screw rod, top nut and counterweight do as a whole continuous decline, when screw thread lower surface, top and the laminating of feeding threaded upper end face, stop declining, test specimen is no longer ground, and amount of grinding reaches requirement.And amesdial is surveyed, be the distance that carrying disk declines, this distance equals the size of test specimen amount of grinding, so can realize on-line measurement.
Advantage of the present invention: according to sample dimensions requirement, by coordinating of feeding screw thread and calibration nut, the size of test specimen amount of grinding can be set in advance; By amesdial, can measure in real time online the size of amount of grinding.
The specific embodiment
A kind of mechanical type face contact amount of grinding on-line measurement device, it is characterized in that: described device is by base pad 1, screw 2, base 3, feeding screw thread 4, calibration nut 5, screw rod 6, locking nut 7, top nut 8, counterweight 9, amesdial 10, amesdial mount pad 11, holding screw 12 and carrying disk 13 form, wherein base 3 tops are provided with amesdial mount pad 11, below is provided with base pad 1, there is ladder hole at base 3 middle parts, in hole, pass the screw rod 6 coordinating with interporal lacuna, screw rod Shang Xia 6 two ends respectively with top nut 8, carrying disk 13 thread connection, screw rod 6 middle part covers have the feeding screw thread 4 with its matched in clearance, feeding screw thread 4 from top to bottom successively with locking nut 7, calibration nut 5 thread connection, feeding screw thread 4 and calibration nut 5 are arranged on respectively in the shoulder hole and draw-in groove of base 3, amesdial 10 is arranged on amesdial mount pad 11, and locate with holding screw 12.
Step while using this measurement device is as follows:
A. test specimen is sticked in the middle of carrying disk 13 lower surfaces;
B. device is placed on smooth horizontal plane, rotary index nut 5, makes its light base 3 of pressing, and writes down now right base 3 positions of calibration nut 5 zero grooves;
C. according to the size of predetermined amount of grinding, the number of turns that reversion calibration nut 5 is certain, with the female locking of locking screw 7;
D. amesdial 10 is arranged on the amesdial mount pad 11 of device, adjusts amesdial 10, make the contact compression carrying disk 13 of amesdial 10, lock-screw 12, writes down the now reading of amesdial 10;
E. device is put on grinder and is ground, from amesdial 10, can read in real time the size of amount of grinding, when amount of grinding reaches predetermined value, nut 8 lower surfaces in top stop the upper surface laminating with feeding spiral shell 4 lines to decline, the grinding of workpiece stops, thereby completes grinding.
