Abstract
The utility model discloses an adjusting mechanism for a circular grating and a reading head. The adjusting mechanism comprises a support (1), the reading head (5), a guide block (2), a slide block (3), a handwheel (4) and a locking screw (6), wherein the support (1) is used as the supporting structure for the whole adjusting mechanism, and the locking screw (6) is in threaded fixation with the guide block (2). During work of the adjusting mechanism, the locking screw (6) is loosened; when the handwheel (4) is rotated clockwise, the guide block (2) retracts, and the reading head (5) is driven to retract; or when the handwheel (4) is rotated anticlockwise, the guide block (2) extends, and the reading head (5) is driven to extend; fine tuning for the gap between the reading head (5) and the circular grating is thus completed; and finally the locking screw (6) is tightened. The goal of rapid adjustment is thus achieved. According to the utility model, rapid adjustment for the reading head is realized by utilizing the principle of mechanical drive, the working efficiency is improved, time is saved and the adjusting process is simplified.
Description
Technical field
The utility model relates to a kind of adjusting mechanism, particularly a kind of round grating reading head adjusting mechanism.
Background technology
Common round grating reading head adjusting mechanism comprises at present: support and read head, wherein read head is connected with the direct screw of support.While adjusting the gap between read head and circle grating, need to move forward and backward support with hand, thereby drive, read head is close or away from circle grating, because read head is higher with circle grating gap precision prescribed, this kind adjusted mode process complexity, is awkward, and length expends time in.
Utility model content
The purpose of this utility model is to provide a kind of round grating reading head adjusting mechanism, solves the problem that current adjusting mechanism adjustment process is complicated, be inconvenient to operate.
A round grating reading head adjusting mechanism, comprising: support, read head, also comprise: orienting lug, slide block, handwheel, lock-screw.
Support is the supporting construction of whole round grating reading head adjusting mechanism.The first half of orienting lug is plane, and the latter half has the square through hole of horizontal direction, and the cross section of the latter half is " returning " font, and orienting lug is jagged away from one end of read head, and there is the threaded hole of vertical direction orienting lug bottom.Orienting lug is placed in support lower end, and fixes with bracket screw.Handwheel is cylindrical, in the middle of handwheel, is tapped through hole, and handwheel is placed in the breach of orienting lug.One end of slide block is dull and stereotyped, and centre is square column, and the other end is screw rod, and flat board, square column, screw rod are formed in one.Slide block is placed in the square through hole of orienting lug, and the screw portion of slide block is through the tapped through hole of handwheel.Read head is placed in the dull and stereotyped outside of slide block, and is connected with the dull and stereotyped screw of slide block.Lock-screw is placed in the threaded hole of orienting lug bottom, and fixes with orienting lug screw.
During the work of circle grating reading head adjusting mechanism, first unclamp lock-screw, while clockwise rotating handwheel, orienting lug is retracted, and drives read head to retract; While rotating counterclockwise handwheel, orienting lug stretches out, and drives read head to stretch out, thereby completes the clearance fine adjustment of read head and circle grating, finally tightens lock-screw, reaches quick-adjustsing object.
The utility model utilizes mechanical drive principle, has designed adjusting mechanism, has realized the rapid adjustment of read head, has improved work efficiency, has saved the time, has simplified adjustment process.

Embodiment
A round grating reading head adjusting mechanism, comprising: support 1, read head 5, also comprise: orienting lug 2, slide block 3, handwheel 4, lock-screw 6.
During the 5 adjusting mechanism work of circle grating reading head, first unclamp lock-screw 6, while clockwise rotating handwheel 4, orienting lug 2 is retracted, and drives read head 5 to retract; While rotating counterclockwise handwheel 4, orienting lug 2 stretches out, and drives read head 5 to stretch out, thereby completes the clearance fine adjustment of read head 5 and circle grating, finally tightens lock-screw 6, reaches quick-adjustsing object.
