Description
Technical field
The invention belongs to field of machining, and in particular to a kind of automatic blanking device.
Background technology
In automated forging line, the forging after previous process is completed generally by being sent into latter work after robot automatic clamping
Following process is carried out in position, in order to the Effec-tive Function of automated forging line.It is general to use on existing forging automatic production line
Device for discharging in, in order to ensure robot clamp space, stripper and forging upper surface distance are increased, stripper is by forging
After pushing punch, forging does the movement of falling object, because apart from angle so that position is not fixed after forging drops, and makes robot
Gripping is convenient.During robot automatic clamping, if clamp space is smaller, difficulty, and machine can be caused to the gripping of robot
People needs first to position to be gripped afterwards, and the time that whole process is spent is long, thus causes work efficiency slack-off.
The content of the invention
It is an object of the invention to provide a kind of automatic blanking device, to improve the efficiency of workpiece blanking.
In order to achieve the above object, base case of the invention is：A kind of automatic blanking device, including rack, in rack
It is equipped with conveyer belt, pedestal, clamping unit and processing unit successively from top to bottom, mounting groove and intercommunicating pore is equipped with vertically on pedestal,
Mounting groove and intercommunicating pore are coaxially disposed and connects, are equipped with locking post, rack and pinion in mounting groove, locking post axial direction equipped with
The locking hole of intercommunicating pore connection, locking post are radially provided with two straight slots along locking post axisymmetrical, and straight slot is connected with locking hole,
The side wall of locking post is also circumferentially with several teeth, and rack is horizontally set on the side wall of mounting groove, and locking post and gear are and tooth
Item engages；Clamping unit includes two gripping blocks being arranged on locking post axisymmetrical on pedestal, and gripping block is equipped with first
Magnet, the lower surface of gripping block are connected with engaging body, and one side of the gripping block away from locking post is fixed with tension spring, the other end of tension spring
Also it is fixed in rack；Processing unit includes fixed cylinder, push rod and processing head, cylinder successively and is fixed on vertically in rack,
Described push rod one end is connected with cylinder slide, and the other end is fixed with processing head, is equipped with and institute close to one end of processing head on push rod
The second attracting magnet of the first magnet is stated, is additionally provided with ball-screw on push rod, the nut on ball-screw is fixed with push rod, ball
Screw rod one end on leading screw is connected with gantry rotation, and the other end is fixed with gear.
The principle of this base case is：Start cylinder, cylinder promotes push rod to move downward by piston rod, and push rod is downward
During movement, on the one hand, the second magnet on push rod is gradually shortened with the first magnet distance in gripping block, and gravitation is gradual
Enhancing, two gripping blocks are mutually drawn close under the action of gravitation, and tension spring is in tensional state at this time；On the other hand, due to nut
It is fixedly connected with push rod, nut can also move downward, and nut, which moves downward, makes screw rod do rotary motion, drive what is be connected with screw rod
Gear rotates, and wheel and rack engagement, gear rotates band carry-over bar and moves horizontally, rack and the tooth engagement in locking post, so as to
Locking post rotates in mounting groove.With the rotation mutually drawn close with locking post of two gripping blocks, when the straight slot in locking post
When opposite with holding section, holding section engages with the moving through straight slot of gripping block and into locking hole when locking post is rotated further by
Portion staggers with straight slot to offset simultaneously with locking post madial wall, so as to which gripping block be locked.After gripping block locking, workpiece is put into folder
It is processed on tight block.After machining, cylinder drives push rod to move upwards again, nut also move upwards drive screw rod, gear,
Rack and locking post counter motion release the locking state of gripping block, while the first magnet and the second magnetic pull are gradually reduced,
Tension spring, which resets, drives gripping block to gradually return to original position, and due to separating for two gripping blocks, the workpiece in gripping block loses clamping
The support force of block will pass through locking hole, intercommunicating pore is fallen on transmission belt automatically, and next processing work is transferred directly to by conveyer belt
In sequence.
The advantageous effect of the technical program is：
1st, set the magnet to attract each other, during push rod moves downward or upward, utilize magnetic in push rod and gripping block
The variation of gravitation size makes two gripping blocks draw close or separate automatically between iron, and two gripping blocks are convenient for the placement of workpiece after drawing close,
Workpiece is just automatically fallen into conveyer belt after gripping block separation, it is no longer necessary to by the clamping discharging of robot, realize workpiece
Automatic blanking improves work efficiency.
The 2nd, ball-screw on push rod is set, the nut on ball-screw is fixed on push rod, utilizes the downward of push rod
Movement drives nut to move downwardly together, so that the screw rod rotation on ball-screw, screw rod rotation band moving gear rotates, gear
Rotation band carry-over bar moves, and rack movement drives locking post to rotate, and locking post rotation makes the holding section in gripping block pass through straight slot
Slip into locking hole and realize the auto lock of gripping block, eliminate artificial locking work, both ensure that gripping block stability and
Reliability, and saved labour.
3rd, during cylinder promotes push rod downward, two the automatic of gripping block had not only been realized and had been drawn close, but also have realized clamping
The locking of block, the power source that cylinder provides have obtained utilizing to greatest extent.
4th, the setting of holding section and locking post not only realizes the locking of gripping block, and after locking, locking post is not rotated further by, right
Gripping block plays supporting role.
Further, push rod is equipped with for by the fixed adapter sleeve of nut.The effect of adapter sleeve is to avoid above and below nut
Nut also rotates when mobile, so as to influence the rotation of screw rod.
Further, engaging body is ball, and ball is rotatablely connected with gripping block.Ball enters in locking hole, when locking post turns
When dynamic, for the inner wall of ball and locking post to be in rolling contact, the friction that the two generates is smaller, to the abrasion of ball and locking post compared with
Small, simultaneously because ball is rotation connection with gripping block, locking post rotation can also be such that ball flexibly rotates, and extend entire
The service life of retaining mechanism.
Further, gripping block is equipped with the locating slot that cross section is arc close to the one side of locking post.Workpiece is put into locating slot
In, workpiece is made more to stablize.
Further, the hole wall of intercommunicating pore and locking hole is equipped with sheet rubber.Sheet rubber has elasticity, workpiece from locking hole and
During intercommunicating pore is fallen, sheet rubber can contact directly and defective work piece to avoid workpiece and hole wall.
Further, the bottom of mounting groove is equipped with gasket.Locking post in mounting groove, the setting of gasket avoid mounting groove with
Locking post, which contacts directly, to be generated frictional heating and causes the abrasion of locking post, while also ensures the rotation precision of locking post, is protected
Card holding section can enter locking hole.
