Description
Technical field
The present invention relates to locks to pay technical field, locks in particular to a kind of screw self-locking device and automatically screw
Machine.
Background technology
With the maturation of mechanical technique, production line imports automated machine and has become in order to which the main of human cost is greatly reduced
Trend.
Existing lock screw machine low production efficiency, and cannot be to waiting for that locking piece carries out lock and pays under varying environment.
Invention content
First of the present invention is designed to provide a kind of screw self-locking device, which can be accurate
Ground treats locking piece and carries out positioning lock pair, can be effectively to waiting for that locking piece carries out lock and pays under varying environment.
Second object of the present invention is that provide one kind locking screw machine automatically, this locks screw machine with above-mentioned automatic automatically
Screw device is locked, can precisely treat locking piece by the automatic lock screw machine carries out positioning lock pair, effectively to being in different
Wait for that locking piece carries out lock and pays under environment.
What the embodiment of the present invention was realized in：
A kind of screw self-locking device, including：
Three-axis drive mechanism；
Screw locking machine structure, screw locking machine structure are connect with Three-axis drive mechanism driving, and screw locking machine structure drives in three axis
It can make respectively along the first preset direction perpendicular to each other, the second preset direction and third preset direction under the driving of motivation structure past
Multiple movement；
Screw locking machine structure has cis-position beak, actuator, electric screwdriver and vacuum absorption device, cis-position beak and electric screwdriver point
It not being sequentially connected with actuator, cis-position beak and electric screwdriver move back and forth under the driving of actuator along third preset direction respectively,
Vacuum absorption device is connect with cis-position beak；
Screw locking machine structure is configured to tool, and there are two types of working conditions：
Normal state, cis-position beak move to third preset direction under the driving of actuator and close to waiting for locking piece, electricity
It criticizes and moves to third preset direction under the driving of actuator and paid by the screw ejection in cis-position beak and with locking piece lock is waited for；
Adsorbed state, cis-position beak generate negative pressure under the action of vacuum absorption device and will wait for that locking piece is adsorbed to cis-position
At beak, electric screwdriver is paid by the screw ejection in cis-position beak and with locking piece lock is waited for；
Positioning device is transmitted, transmission positioning device has transport mechanism and lifting body, and transport mechanism, which is constructed, to be waited for
Locking piece moves along the second preset direction, and when locking piece arrives at precalculated position, lifting body will wait for locking piece jacking simultaneously
It is detached from transport mechanism, screw locking machine structure carries out lock and pays.
Inventor has found：When carrying out lock pair to workpiece, the environment residing for workpiece is different, and common lock, which pays mode, to be met
Demand, so as to cause the pinning failure of workpiece.It is installed for example, the lock of filter cover board is paid, raised electricity on wave device cover board
Sub- device, near screw and the screw lock of cover board water-proof edge pay that space is smaller, and according to common pinning mode, lock is paid
When carrying out lock under mechanism and paying, due to, screw posture out of plumb, bad with screwdriver bit concentricity, lead to that lock pair cannot be carried out.
For this purpose, inventor devises above-mentioned screw self-locking device, which can precisely treat lock and pay
Part carries out positioning lock and pays, can be effectively to waiting for that locking piece carries out lock and pays under varying environment.Screw self-locking device includes

Inventor has found：When carrying out lock pair to workpiece, the environment residing for workpiece is different, and common lock, which pays mode, to be met
Demand, so as to cause the pinning failure of workpiece.It is installed for example, the lock of filter cover board is paid, raised electricity on wave device cover board
Sub- device, near screw and the screw lock of cover board water-proof edge pay that space is smaller, and according to common pinning mode, lock is paid
When carrying out lock under mechanism and paying, due to, screw posture out of plumb, bad with screwdriver bit concentricity, lead to that lock pair cannot be carried out.
For this purpose, inventor devises above-mentioned screw self-locking device 10, which can precisely treat
Locking piece carries out positioning lock and pays, can be effectively to waiting for that locking piece carries out lock and pays under varying environment.Screw self-locking device
10 include Three-axis drive mechanism 11, screw locking machine structure 12 and transmission positioning device 13.Wherein, screw locking machine structure 12 is three
It can be respectively along the default side of the first preset direction perpendicular to each other, the second preset direction and third under the driving of axis driving mechanism 11
To reciprocating, as a result, in working face, can lock effectively be carried out to each screw hole and paid.By transmitting positioning device 13
In transport mechanism 130 so that wait for locking piece transmission positioning device 13 transmission under, and transmission positioning device 13 jacking
Mechanism 131 so that part to be locked pays position to preset lock and carries out lock pair by screw locking machine structure 12.It is different due to overcome
Lock pays environment, and there are two types of the working conditions that lock is paid for the tool of screw locking machine structure 12：Normal state and adsorbed state.Wherein, screw is locked
Paying mechanism 12 has cis-position beak 120, actuator, electric screwdriver 121 and vacuum absorption device.Normal state is：When lock pays environment
It is good, meet common pinning mode, then cis-position beak 120 move to third preset direction under the driving of actuator and close waited for
Locking piece, electric screwdriver 121 move to third preset direction under the driving of actuator and eject the screw in cis-position beak 120 simultaneously
It carries out lock with locking piece is waited for and pays.Adsorbed state is：When lock is paid, environment is bad, and lock pair space is small, screw posture out of plumb and screwdriver bit
When concentricity is bad, for example, in the case where the lock of filter cover board upper cover plate water-proof edge pays installation, cis-position beak 120 is inhaled in vacuum
Negative pressure is generated under the action of adsorption device and will wait for that locking piece is adsorbed at cis-position beak 120, and electric screwdriver 121 will be in cis-position beak 120
Screw ejection and with wait for locking piece carry out lock pay.The screw self-locking device 10 can precisely treat locking piece and carry out positioning lock
It pays, it can be effectively to waiting for that locking piece carries out lock and pays under varying environment.
