Description
Technical field
The invention belongs to non-contact automatic transporting field, especially a kind of block form binary vortices for inhibiting workpiece rotation are non-to be connect
Touch vacuum chuck.
Background technique
Non-contact vacuum sucker can be divided into Bernoulli Jacob's formula Non-contact vacuum sucker and vortex Non-contact vacuum sucker,
Since vortex Non-contact vacuum sucker has the advantages that air consumption is small, suction force is big than Bernoulli Jacob's formula vacuum chuck, so should
Kind structure is more expected, and has more industrial application value in the energy-efficient today's society of advocating environment protection.But vortex is non-contact true
During suction takes, due to the presence of swirling eddy, the case where workpiece will appear rotation, leads to the unstable of suction process, make
Workpiece may be in contact to destroying non-contact absorption with sucker bottom, when but will destroy non-contact absorption when serious
Dynamic equilibrium.
The case where industrially rotating for workpiece at present, fragrant river professor Li Chun propose a kind of identical using three pairs of sizes
Non-contact vacuum sucker composition end effector mechanism, each pair of sucker is oppositely oriented, and rotation is passed through in the sucker being symmetrically installed
To opposite gas, thus the turning moment that workpiece of cancelling out each other is subject to.But for drawing the lesser workpiece of geometric dimension, by
Limitation in terms of space, can not in pairs using, be symmetrically installed, which results in the feelings that workpiece can rotate in suction process
Condition greatly affected the reliability of Non-contact vacuum absorption.Therefore it needs a kind of small volume, workpiece rotation can be prevented
Vortex Non-contact vacuum sucker.
Summary of the invention
The purpose of the present invention is to provide a kind of block form binary vortices Non-contact vacuum suckers for inhibiting workpiece rotation, with reality
Now solve the Rotation of workpiece in Non-contact vacuum suction process.

Specific embodiment
With reference to the accompanying drawing and specific embodiment is described further the present invention.
In conjunction with Fig. 1-Fig. 6;A kind of block form binary vortices Non-contact vacuum sucker of inhibition workpiece rotation of the invention, including
Upper end cover 1, lower cover 3;It is fixedly connected between the upper end cover 1 and lower cover 3 by screw 4;The upper end cover 1 and lower cover
Toroidal cavity 6 is equipped between 3;It is symmetrically arranged on the lower cover 3 in two cylinders 3-1, the cylinder 3-1 and is equipped with air inlet 2;
The air inlet 2 is tapped blind hole;The air inlet 2 is equipped with venthole 10;The venthole 10 be through-hole, venthole 10 with
Toroidal cavity 6 is connected to;Sealing device is equipped between the upper end cover 1 and lower cover 3, to be sealed to toroidal cavity 6;It is described
3 bottom symmetrical of lower cover is set there are two circulation chamber 7, and 7 central boss of circulation chamber is as circulation body 8;Two circulation chambers 7 are respectively with two
A air inlet 2 is coaxial;7 outer ring of circulation chamber is evenly distributed with four tangential nozzles 11, and is located at tangential nozzle on the same circulation chamber 7
11 rotation directions are identical, and the tangential nozzle 11 of two circulation chambers 7 is oppositely oriented;Such as the tangential nozzle 11 of first circulation chamber 7 is suitable
When hour hands rotation direction, the tangential nozzle 11 of second circulation chamber 7 is rotation direction counterclockwise.The tangential nozzle 11 is used for toroidal cavity
6 are connected with circulation chamber 7.When block form binary vortices sucker works, (arrow indicates eddy flow side to schematic diagram in enclosing as shown in Figure 6
To enclosing outer arrow indicates the direction that eddy flow generates).Since four tangential nozzles of each vortex are central symmetries
, the frictional force that eddy flow generates workpiece can be equivalent to 1.~8. shown in, in this way, frictional force 1. with 2. mutually balance each other, 3. with
4. mutually balancing each other, 5., 6. with 7., 8. mutually balance each other, so that the frictional force that two eddy flows generate offsets each other, ensure that non-contact
The stability of vacsorb process.
Further, the first chamfering 12 is equipped on the outside of the circulation chamber 7, first chamfering 12 is fallen for ladder twice
Angle;So that 7 outside of circulation chamber is in bell-mouth structure of air downwards, the vibration of workpiece when can weaken the work of vortex Non-contact vacuum sucker
It swings.
Further, the second chamfering 9 is equipped on the outside of the circulation body 8, so that the V-shaped structure of circulation body 8, can be improved whirlpool
The suction force of rotating Non-contact vacuum sucker.
As an implementation, the positional symmetry that the upper end cover 1 is contacted with 3 upper surface of lower cover set there are two annular
Slot 5;Two annular grooves 5 are coaxial with two air inlets 2 respectively;Sealing ring is equipped in annular groove 5;3 bottom of lower cover is equipped with
One circle flange 3-2;The position that 1 lower end of upper end cover is contacted with flange 3-2 is equipped with circle a seal groove 1-1, seal groove 1-1
It is interior to be equipped with sealing ring;The upper and lower ends of toroidal cavity 6 for being sealed by seal groove 1-1 and two annular grooves 5.
Further, the upper end cover 1, lower cover 3 are in kidney ellipsoid structure, ring lumen diameter is identical, two annular chambers
It can reduce the size of sucker in the case that centre distance is equal.
The block form binary vortices Non-contact vacuum sucker course of work of the invention are as follows: compressed air enters from air inlet 2, warp
Cross through hole 10 enters toroidal cavity 6, then is projected by tangential nozzle 11, in the intracavitary high speed rotation of circulation, due to centrifugal force
In the presence of the air at circulation chamber center is thrown to circulation cavity wall face and rotate together at high speed with eddy flow, thus in circulation chamber bottom centre
Negative pressure is generated, this negative pressure picks up workpiece under the collective effect of workpiece bottom atmospheric pressure, and since eddy flow is from sucker
Gap discharge between bottom and workpiece surface, has the presence of an air damping to workpiece, the damping force and workpiece weight
Power direction all straight down, so ensure that untouchable in suction process.And since block form binary vortices of the invention are non-
Vacuum chuck structure is contacted, two oppositely oriented eddy flows are generated in suction process, is being passed through uniform pressure, same traffic
After air, two eddy flow sizes, intensity are equal, contrary, equal in magnitude, contrary rub so generating two to workpiece
Torque is wiped, is mutually balanced between two moment of frictions, to inhibit the rotation of workpiece in Non-contact vacuum suction process, is guaranteed
The stability of suction process.
