Clamping device, mechanical paw and the method for carrying implemented by the mechanical paw
Technical field
The present invention relates to mechanical devices, and in particular to clamping device, mechanical paw and is removed by what the mechanical paw was implemented
Transportation method.
Background technology
During existing actual industrial production, it is typically necessary and the several processes of workpiece point is processed, therefore need
Workpiece is taken out, is put into the processing unit (plant) of second process and is processed, if desired manually this generic operation is carried out, then operates
Single, repetition is acted, and inconvenient, low production efficiency, and be easy to damage and pollute workpiece, it then passes through using manipulator
It solves these problems, but many volumes of existing manipulator are larger, without protection structure between mechanical paw and workpiece, is easy
Trace is generated on workpiece, clamping is unstable, and the larger manipulator of volume is not suitable for some junior machines yet.
Invention content
To solve the above-mentioned problems, the invention discloses a kind of mechanical paws.
Present invention technical solution used for the above purpose is:A kind of clamping device comprising pushing material component, drive

The sliding slot that several horizontal directions are provided on the shell of hydraulic cylinder is stated, the sliding block is movably arranged on the sliding slot, the cunning
The corresponding pushing block, which is provided with, on the inside of block fixes with matched second inclined-plane in first inclined-plane, the clamping jaw with the sliding block
Connection, the pushing material component can be up or down arranged on the outside of the hydraulic cylinder.For having the workpiece of pore structure, hydraulic cylinder work
Make, piston rod pushes pushing block to push, and second inclined-plane on the first inclined-plane and sliding block on the outside of pushing block is corresponding, and pushing block pushes, sliding block
It is pushed outwardly, because sliding block is movably arranged on the sliding slot being arranged on the shell of hydraulic cylinder, sliding block does the outside shifting of horizontal direction
Dynamic, several clamping jaws in pore structure push out the clamping realized to workpiece jointly.
The pushing material component includes scraping wings, several guide rods and compression spring corresponding with the guide rod quantity, described
Hydraulic cylinder outside spacers are equally equipped with the mounting plate with the guide rod quantity etc., and the guide rod upper end is provided with block, institute
It states guide rod end to wear above the mounting plate to the mounting plate, the scraping wings is provided with and the guide rod quantity phase
Corresponding plate arm, the plate arm are fixedly connected with the guide rod end, and compression spring setting is in the mounting plate and described
Between scraping wings.Workpiece pushes scraping wings, scraping wings compression pressure spring to move up, and clamping jaw enters the pore structure of workpiece at this time
It is interior, setting position rear clip-claw clamping workpiece is arrived, because clamping jaw has chucking power, compression spring to keep confined state workpiece, when
Chucking power disappears, and compression spring pushes pusher sheet reset, releases workpiece, realizes automatic release workpiece, increases production efficiency.
The pushing block upper end setting is fluted, and the resetting spring for resetting the sliding block is equipped in the groove,
The front end of the resetting spring is connect with the shell of the hydraulic cylinder, and the end of the resetting spring and the cell wall of the groove connect
It connects.The piston rod of hydraulic cylinder moves up, and pushing block is driven to move up, and pushing block disappears to the extruding force of sliding block, and resetting spring restores shape
Become, pawl return.
The housing exterior walls of the hydraulic cylinder be provided with it is several for incude the scraping wings close to switch.When workpiece pushes
Setting position is moved on on scraping wings, close to inductive switching to scraping wings, is closed close to switch, the operating circuit connection of hydraulic cylinder,
Hydraulic cylinder is started to work, and driving clamping jaw is implemented to be clamped to workpiece.
It is provided with antiskid rubber on the outside of the clamping jaw.When clamping workpiece, there is antiskid rubber to be clipped among clamping jaw and workpiece, increases
Big frictional force keeps clamping more stable, and avoids the rigid collision of clamping jaw and workpiece, avoids pollution and damage to workpiece.
A kind of mechanical paw comprising two clamping devices and rotating device recited above, the rotating device include
Rotary cylinder and fixed plate for fixed clamping device, the fixed plate are fixedly connected with the rotary cylinder, the fixation
Plate lower surface is provided with two symmetrical constant inclined surfaces, and two clamping devices are individually fixed in a constant inclined surface
On.Two constant inclined surfaces are symmetrical, can as needed to the target location of workpiece handling be arranged constant inclined surface gradient, and because
It is fixed symmetrical for two constant inclined surfaces, the clamping device being fixed on two constant inclined surfaces can work alternatively, and improve production
Efficiency.
The connecting plate for being useful for connection process equipment is fixedly connected with above the rotary cylinder.It is connected and is processed by connecting plate
Equipment avoids rotary cylinder from directly being connected with process equipment, extends the service life of rotary cylinder.
A kind of method for carrying implemented by the mechanical paw comprising following steps:
Step 1, workpiece are pushed towards clamping device, and workpiece squeezes pushing material component, and workpiece is pushed to move on on pushing material component and be set
Positioning is set, Driven by Hydraulic Cylinder clamping jaw clamping workpiece;
Step 2, rotary cylinder start, and rotary cylinder drives fixed plate to rotate set angle, and fixed plate drives clamping device
It rotates to destination locations;
Step 3, pawl return, pushing material component release workpiece, complete the carrying to workpiece.
In the step 1, workpiece squeezes scraping wings, and scraping wings squeeze pressure spring, workpiece is tactile together with being moved on scraping wings
Hair is started to work close to switch, hydraulic cylinder, and the piston rod of hydraulic cylinder pushes pushing block to push, and the first inclined-plane of pushing block squeezes on sliding block
The second inclined-plane, the outer shipper pole of sliding block moves and moved outside clamping jaw, clamps workpiece.
In the step 3, the piston rod of hydraulic cylinder moves up, and piston rod drives pushing block to move up, answering in upper end of slide block groove
Position spring pushes sliding block to reset, and sliding block drives pawl return, the pressure bullet that corresponding guide rod is arranged between scraping wings and mounting plate
Spring pushes scraping wings, pusher sheet reset to realize and release workpiece.
Beneficial effects of the present invention are:Structure of the invention reasonable design is ingenious, small, the design of pushing material component, can
Workpiece is released well, the resetting spring installed on sliding block, is convenient for the reset of clamping jaw, the housing exterior walls of hydraulic cylinder, which are provided with, to be connect
Nearly switch, realizes the automatic clamping to workpiece, by the antiskid rubber being arranged on the outside of clamping jaw, increases clamping stability, avoids
Damage and pollution to workpiece is worked alternatively by two clamping devices being fixed on two constant inclined surfaces, improves life
Produce efficiency.
Below in conjunction with the accompanying drawings with specific implementation mode, the present invention is further described.
