Therefore, how to allow and design a kind of adjustable grasping mechanism of automatic centering, so that transmission efficiency improves, crawl movement is flat
Surely, and grasp width can be adjusted in a certain range, become current field technical staff urgent problem to be solved.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of automatic centerings can adjust grasping mechanism, realizes and improve crawl
Stationarity, and gripping block can be realized automatic centering crawl.
In order to achieve the above object, the invention provides the following technical scheme:
A kind of adjustable grasping mechanism of automatic centering, including gripping block, rack gear, sector gear, motor, shell plates, feature exist
In there is sliding slot in the gripping block lower end, and there is screw hole in side, and the upper end of the rack has slideway, and the sector gear has circular hole, described
Shell plates upper and lower side has slideway and has circular hole.
Preferably, there are two above-mentioned gripping blocks, the slideway on above-mentioned rack gear top is closely stuck in by the sliding slot of bottom end respectively
On, side passes through screw hole bolt fastening.
Preferably, it there are two above-mentioned rack gears, is closely stuck in the sliding slot of above-mentioned shell plates by the slideway of bottom end respectively, and
It can slide along the chute.
Preferably, again close with above-mentioned rack gear respectively after two sector gear intermeshings there are two above-mentioned sector gears
Engagement, and by circular hole and said motor axis connection, use bolt fastening.
Preferably, said motor is bolted on above-mentioned shell plates.
Preferably, above-mentioned shell plates are divided into two pieces, have sliding slot for providing tracks and support for above-mentioned rack gear, and
Two pieces of shell plates are bolted to form complete shell protection internal mechanism.
The present invention provides a kind of adjustable grasping mechanism of automatic centering, including gripping block, rack gear, sector gear, motor, shell
Body plate, wherein the gripping block is connect with the rack gear, and the rack gear is engaged with the sector gear, the sector gear with
The motor connection, the shell plates are divided into two pieces, support the rack gear.When work, motor rotation drives one by shaft coupling
The rotation of side sector gear, this side sector gear drives the rotation of other side sector gear by engagement, while two sector gears divide again
It is not engaged with rack and is translated in opposite directions with carry-over bar, rack drives gripping block clamps at this time.At the end of, motor rotates backward, and leads to
It crosses shaft coupling and drives the rotation of side sector gear, this side sector gear drives the rotation of other side sector gear by engagement, simultaneously
Two sector gears are engaged with rack respectively and reversely translate with carry-over bar again, and rack drives gripping block is unclamped at this time.Whole process
Flexibly simple, the transmission efficiency of sector wheel and rack is higher, and mechanism kinematic is easily achieved, and two sector gears and two
Rack-driving is steady, can be realized automatic centering crawl, i.e. two gripping blocks move toward one another crawl simultaneously.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is the present invention
Some embodiments for those of ordinary skill in the art without creative efforts, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 is front view of the invention.
Fig. 2 is shaft side figure of the invention.
Fig. 3 is left view of the invention.
In attached drawing described above: gripping block 1, rack gear 2, sector gear 3, shell plates 4, motor 5.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical solution in the embodiment of the present invention is into ingeniously clearly and completely describing, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
According to attached drawing described above, there are two gripping blocks 1, is closely stuck in 2 top of rack gear by the sliding slot of bottom end respectively
On slideway, side is by screw hole bolt fastening, and there are two rack gears 2, is closely stuck in shell plates 4 by the slideway of bottom end respectively
In sliding slot, and can slide along the chute, there are two sector gears 3, two sector gears 3 be intermeshed after again respectively with rack gear 2
It tightly engages, and by circular hole and 5 axis connection of motor, with bolt fastening, motor 5 is bolted on shell plates 4, shell
It is two pieces that body plate 4, which is divided to, has sliding slot for providing tracks and supporting for rack gear 2, and two pieces of shell plates 4 are bolted
Form complete shell protection internal mechanism.
The present invention works in this way: when work, the rotation of motor 5 drives side sector gear 3 to rotate by shaft coupling, this side fan
