With moving up and down for grinding wheel spindle sliding block realized respectively by two separate drive mechanisms, cause the movement of trimmer
Movement with emery wheel can not be coordinated, it may appear that and trimmer finishing excessive to emery wheel or situation about can not repair occur, and this
Two kinds of situations occur at random, it is difficult to overcome.Meanwhile occur at random it is excessive to emery wheel finishing or can not repair, also lead
Having caused the grinding accuracy of workpiece can not ensure.
The content of the invention
The purpose of this technology be to provide it is a kind of being capable of the accurately and timely change with emery wheel position and grinding wheel cylindrical size
Change and adjust the dresser location following mechanism of dresser position, it ensure that trimmer is repaiied to the accurate of emery wheel
It is multiple, it ensure that the grinding accuracy of workpiece.
The technical scheme taken for this this technology is：Dresser location following mechanism, when repairing emery wheel with trimmer
Connecting line with the finishing point and emery wheel axis of grinding wheel cylindrical contact is glide direction, and grinding wheel spindle is disposed relative to frame in institute
State on the grinding wheel spindle sliding block slided in glide direction, what trimmer was disposed relative to that frame slides in the glide direction repaiies
On whole device sliding block, rotate set frame on a screw mandrel on respectively have with grinding wheel spindle sliding block coordinate emery wheel axle thread and with
The trimmer screw thread that trimmer sliding block coordinates, trimmer thread pitch is twice of grinding wheel spindle thread pitch；When screw mandrel rotates, repair
Whole device sliding block displacement in the glide direction is grinding wheel spindle sliding block twice of displacement in the glide direction.
Above-mentioned dresser location following mechanism, for trimmer in the top of emery wheel, the glide direction is upper and lower
To.
Above-mentioned dresser location following mechanism, it also includes the driving machine rotated with drive screw that is connected with screw mandrel
Structure.
Above-mentioned dresser location following mechanism, it also includes the handwheel rotated with drive screw that is connected with screw mandrel.
The beneficial effect of this technology：There are two kinds of different screw threads of pitch, i.e. trimmer spiral shell in this technology, on a leading screw
Line and emery wheel axle thread, trimmer thread pitch are twice of grinding wheel spindle thread pitch；The root leading screw by trimmer screw thread with
Trimmer sliding block coordinates, while is coordinated by emery wheel axle thread and grinding wheel spindle sliding block, so during rotational lead screw, trimmer sliding block exists
The distance moved on leading screw axial direction is twice of grinding wheel spindle displacement, thus trimmer displacement is emery wheel movement
Twice of distance.When abrasion of grinding wheel s distances（Radius reduces s）Afterwards, in order to ensure grinding points position that emery wheel contacts with workpiece not
Become, it is necessary to be rotated by leading screw, the glide direction such as drive grinding wheel spindle sliding block, emery wheel moves s towards workpiece.Due to emery wheel movement away from
Reduce s from s and grinding wheel radius, therefore, the finishing point positional distance after the finishing point position before emery wheel movement is moved with emery wheel is
2s.This technology is driven trimmer and emery wheel simultaneously mobile, realized by the screw thread of two sections of different pitch on a leading screw
Trimmer displacement is twice of emery wheel displacement all the time.
