Detailed description of the invention
Below the present invention is described in further details.
The most referring also to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.
The dual-purpose slide calliper rule of dual-purpose to be repaired are from top to bottom loaded in pedestal 1 in groove 10 by 1, use lock-screw [30] tight
Gu, abrasive sheet 2 is put into the quiet measuring jaw c26 of dual-purpose slide calliper rule, quiet measuring jaw d27 and dynamic measuring jaw a28, dynamic measuring jaw b29 before backward
Between, both are connected by hole thereon by abrasive sheet 2 with action shaft 14 connecting pin 19.
2 are from top to bottom sequentially placed into spring base 22, spring 21, regulating block 20 in main scale 24.Lower pressure regulating block 20, makes bullet
Spring 21 reduced size is the pretightning force that 20mm produces 10N, in screw-in screw 23 to regulating block 20 respective aperture, and locked regulating block 20.
Abrasive pastes are estimated uniform application in abrasive sheet 2 upper and lower surface by 3.
4 start servomotor 4, and band moving cam 7 rotates.When the short axle point of cam 7 contacts with bearing 16, grind
Plate 2 is in right limit operating position, and when both contact points are changed to major axis point by the short axle point of cam 7, cam 7 passes through
Bearing 16 drives action shaft 14 to be moved to the left, thus drives abrasive sheet 2 to enter grinding motion to the left, can repair dual-purpose simultaneously
Two groups of sound measuring jaws of slide calliper rule；When the major axis point of cam 7 contacts with bearing 16, abrasive sheet 2 is in maximal work position, left side,
When both contact points are changed to short axle point by the major axis point of cam 7, under the effect of back-moving spring 15, action shaft 14 is to the right
Mobile, thus drive abrasive sheet 2 to enter to the right grinding motion, two groups of sound measuring jaws of dual-purpose slide calliper rule also obtain synchronizing to repair.
Servomotor continuous running, can realize the sound measuring jaw of dual-purpose slide calliper rule is persistently repaired grinding.
