Description
Technical field
The invention belongs to field of machining, and in particular to a kind of automatic blanking device.
Background technique
In automated forging line, the forging after completing previous process is sent into latter work after generally passing through robot automatic clamping
Following process is carried out in position, in order to the efficient operation of automated forging line.It is general to use on existing forging automatic production line
Device for discharging in, in order to guarantee robot clamp space, stripper and forging upper surface distance are increased, stripper is by forging
After pushing down formed punch, forging does the movement of falling object, because, so that forging falls rear position and is not fixed, making the problems such as distance, angle
Robot clamping is inconvenient.When robot automatic clamping, if clamp space is smaller, difficulty can be caused to the clamping of robot,
And robot is needed first to position and be clamped afterwards, and the time that whole process is spent is long, thus causes working efficiency slack-off.
Summary of the invention
The purpose of the present invention is to provide a kind of automatic blanking devices, to improve the efficiency of workpiece blanking.
In order to achieve the above object, base case of the invention are as follows: a kind of automatic blanking device, including rack, in rack
It is successively arranged conveyer belt, pedestal, clamping unit and processing unit from top to bottom, is equipped with mounting groove and intercommunicating pore vertically on pedestal,
Mounting groove and intercommunicating pore are coaxially disposed and be connected tos, 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 through slots along locking post axisymmetrical, and through slot is connected to locking hole,
The side wall of locking post is also circumferentially with several teeth, and rack gear is horizontally set on the side wall of mounting groove, and locking post and gear are and tooth
Item engagement；Clamping unit includes two gripping blocks being set on the base with locking post axisymmetrical, and gripping block is equipped with first
Magnet, the lower surface of gripping block are connected with engaging body, and gripping block is fixed with tension spring, the other end of tension spring far from the side of locking post
Also it is fixed on the rack；Processing unit includes the cylinder, push rod and processing head successively fixed, and cylinder is fixed on the rack vertically,
Described push rod one end is connect with cylinder slide, and the other end is fixed with processing head, is equipped with and institute on push rod close to one end of processing head
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 lead screw is connect with gantry rotation, and the other end is fixed with gear.
The principle of this base case is: starting cylinder, cylinder push 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 gradually
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, what drive was connect with screw rod
Gear rotation, wheel and rack engagement, gear rotation band carry-over bar move horizontally, the tooth engagement on rack gear and locking post, thus
Locking post rotates in mounting groove.With the rotation of two gripping blocks mutually drawn close with locking post, when the through slot in locking post
When opposite with holding section, holding section enters locking hole, engaging when locking post is rotated further by with the moving through through slot of gripping block
Portion is staggered with through slot and offsets simultaneously with locking post inner sidewall, so that gripping block be locked.After gripping block locking, workpiece is put into folder
It is processed on tight block.After processing is completed, cylinder drives push rod to move upwards again, nut also move upwards drive screw rod, gear,
Rack gear 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, be transferred directly to next processing work by conveyer belt
In sequence.
The beneficial effect of the technical program is:
1, the magnet to attract each other is set in push rod and gripping block and utilizes magnetic during push rod moves downward or upward
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.
2, ball-screw is set on push rod, the nut on ball-screw is fixed on push rod, the downward of push rod is utilized
Movement drives nut to move downwardly together, so that the screw rod on ball-screw be made to rotate, screw rod rotation band moving gear rotates, gear
Rotation band carry-over bar is mobile, and rack gear is mobile to drive locking post rotation, and locking post rotation makes the holding section in gripping block pass through through slot
Slide into locking hole and realize the automatically lock of gripping block, eliminate artificial locking work, both ensure that gripping block stability and
Reliability, and saved labour.
3, during cylinder pushes push rod downward, drawing close automatically for two gripping blocks had not only been realized, but also realize clamping
The locking of block, the power source that cylinder provides have obtained maximum utilization.
4, the setting of holding section and locking post not only realizes the locking of gripping block, and after locking, locking post is no longer rotated, right
Gripping block plays supporting role.
Further, push rod is equipped with for the adapter sleeve that nut is fixed.The effect of adapter sleeve is to avoid nut or more
Nut also rotates when mobile, to influence the rotation of screw rod.
Further, engaging body is ball, and ball and gripping block are rotatablely connected.Ball enters in locking hole, when locking post turns
When dynamic, the inner wall of ball and locking post is to be in rolling contact, and the friction that the two generates is smaller, to the abrasion of ball and locking post compared with
Small, simultaneously because ball and gripping block are rotation connections, 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 side of locking post.Workpiece is put into locating slot
In, keep workpiece more stable.
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 directly be contacted and defective work piece to avoid workpiece with 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 directly contacts the abrasion for generating frictional heating and causing locking post, while also ensuring the rotation precision of locking post, protects
Card holding section is able to enter locking hole.
