Description
Technical field
The present invention relates to a kind of clamping mechanisms, and in particular to a kind of realize under the action of air operated reversing valve is persistently stepped up
Mechanism.
Background technology
Clamping mechanism is widely used, grasps as the term suggests being exactly to step up to be processed or other processing by workpiece in production
Facilitate.But current workpiece clamping mechanism can step up workpiece, but air source is sudden shut off under conditions of air source abundance
When, clamping mechanism can run out of steam, and gripping finger is made to lose grip, increase the insecurity of operation.
Invention content
In order to solve the problems, such as to can not achieve in the prior art it is automatic continuous step up and safety is low, the present invention provides
Rack-and-pinion a kind of easy to operate and high-efficiency continuous can stepping up continues clamping mechanism.
The invention is realized by the following technical scheme：
A kind of rack-and-pinion continues clamping mechanism, including pedestal, be provided on pedestal cylinder, rack and pinion drive mechanism and
Gripping finger, rack and pinion drive mechanism include rack and two gears, and two gears are symmetricly set on rack both sides, and simultaneously and tooth
Item engages, and rack connects piston rod one end of cylinder, and the piston rod other end of cylinder connects reversal valve, and gear is connect with gripping finger.
Said gear rack continues clamping mechanism preferred embodiment, and reversal valve is two-position four-way air operated reversing valve.
Said gear rack continues clamping mechanism preferred embodiment, and piston rod and the rack of cylinder are rigid connection.
Said gear rack continues clamping mechanism preferred embodiment, is toothed around in the semi-circumference of gear, in addition semi-circumference is
Shiny surface.
Said gear rack continues clamping mechanism preferred embodiment, the smooth part of gripping finger one end connection gear, and the other end is
Bending structure, and separate one end being connect with gear is arcuate structure.
The advantage of the invention is that：Workpiece need to be only put in gripping finger by user of service, opened air source and started reversal valve, lead to
The forward movement of rack is crossed, gear rotates inward, and then gripping finger can step up workpiece, is broken because unexpected in air source,
In the case of running out of steam, gripping finger remains under the protection for starting reversal valve, is clamped to workpiece, is just effectively ensured in this way
It remains to step up workpiece holding in the unexpected gripping finger such as unexpected power-off, protects the safety of operating personnel.
Description of the drawings
Attached drawing is used to provide further understanding of the present invention, and a part for constitution instruction, the reality with the present invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is cylinder and reversal valve connection diagram.
In figure, 1 air cylinder；2 pistons；3 pedestals；4 gears；5 racks；6 gripping fingers；7 two-position four way change valves.
Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
With reference to figure 1 and Fig. 2, a kind of rack-and-pinion continues clamping mechanism, including pedestal 3, and cylinder 1, tooth are provided on pedestal
Rack gear and gripping finger 6 are taken turns, rack and pinion drive mechanism includes rack 5 and two gears 4, and two gears 4 are symmetrical arranged
It in 6 both sides of rack, and is engaged simultaneously with rack 5, rack 5 connects 2 one end of piston rod of cylinder 1, and the piston rod 2 of cylinder 1 is another
End connection reversal valve 7, gear 4 are connect with gripping finger 6, and the smooth part of 6 one end connection gear 4 of gripping finger, the other end is bending structure,
And separate one end being connect with gear 4 is arcuate structure.
In the present embodiment, reversal valve 7 is two-position four-way air operated reversing valve.
In the present embodiment, piston rod 2 and the rack 5 of cylinder 1 are rigid connection.
It in the present embodiment, is toothed around in the semi-circumference of gear 4, in addition semi-circumference is shiny surface.
Workpiece to be clamped need to be only put into gripping finger 6 by user of service, opened air source and started reversal valve 7, the control of cylinder 1 is lived
The movement of stopper rod 2, piston rod 2 is rigidly connected with rack 5, while controlling the movement of rack 5, and rack 5 can drive while movement
Gear 4 rotates, and two gears 4 rotate simultaneously, and workpiece will be stepped up by gripping finger 6, in the case where air source is broken suddenly, gripping finger 6
Also can continue to step up workpiece under the protection of air operated reversing valve.This rack-and-pinion, which continues clamping mechanism, to be ensured
The safety of user of service, it is easy to use.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
With technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
