Description
Technical field
The present invention relates to precision machinery technology field, and in particular to laser marking machine.
Background technology
Application No. 201720016205.8, the utility model patent that Authorization Notice No. is the U of CN CN 206373491 are public
A kind of intelligent vision positioning laser marking machine is opened, laser is carried out under the driving of first driving means and the second drive device
The movement of multiple dimensions, to precalculated position, mark is carried out to product.
Above-mentioned drive device is typically made up of motor and screw body, and under the driving of motor, screw body can make laser
Device stops at an arbitrary position, still, motor caused inertia during driving, may make laser out of position.
The content of the invention
Technical problem solved by the invention：Under the driving of drive device, how to make the laser of marking machine exactly
Rest on precalculated position.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of linearly moving laser marking machine, bag
Include substrate, the drive device on substrate, the laser being slidably fitted on dragging track provided with dragging track, driving
Device drives the laser to be moved along dragging track；The drive device includes motor, screw mandrel, cooperation the screw mandrel on screw mandrel

The rotating cylinder that is connected on plate-like base, the drag ring on plate-like base and in rotating cylinder, it is articulated in plate-like base
Rotary shaft upper and in drag ring；Rotary shaft outer surface is provided with the chute of axial direction, and slide cartridge up and down is arranged with rotary shaft, on
The madial wall of lower slide cartridge is provided with the sliding block coordinated with the chute；U-shaped chute is opened up on the lateral wall of upper and lower slide cartridge, U-shaped is slided
The both ends open of groove is located on the top end face of upper and lower slide cartridge；The upper and lower bottom end face of slide cartridge and the top end-face friction of drag ring
Contact, the drag ring are flexible；The madial wall of rotating cylinder is provided with drive rod, and drive rod is oppressed at the top of upper and lower slide cartridge
On end face；The center line of rotating cylinder overlaps with the axial line of rotary shaft；The motor is connected with the rotating cylinder, the rotary shaft
It is connected with the screw mandrel.
In above-mentioned technical proposal, the operation principle of transmission device is as follows.Original state, drive rod are oppressed in upper and lower slide cartridge
On the end face of top, the elasticity of axial direction occurs for the bottom end face of upper and lower slide cartridge and the top end face CONTACT WITH FRICTION of drag ring, drag ring
Deform and gather elastic potential energy.Rotating cylinder rotates, and drive rod rotates with, because drag ring is to the frictional force of upper and lower slide cartridge, on
Lower slide cartridge remains stationary, correspondingly, rotary shaft remains stationary, drive rod are slided on the top end face of upper and lower slide cartridge.Drive rod
Slide into U-shaped chute to be released in the opening at the top of upper and lower slide cartridge on end face, the elastic potential energy of drag ring, drive rod enters
U-shaped chute.Rotating cylinder keeps rotation, and the drive rod in U-shaped chute can be analyzed to radial component to the active force of upper and lower slide cartridge
And axial thrust load, slide cartridge lifts along rotary shaft up and down for the axial thrust load driving, the radial component driving slide cartridge rotation up and down,
Upper and lower slide cartridge driving rotary shaft rotation.
If U-shaped chute both ends open is respectively head end opening and tail end opening, head end opening to U-shaped chute minimum point it
Between chute be the left half section of chute of U-shaped chute, U-shaped chute minimum point to the chute between tail end opening is that U-shaped chute is right half section
Chute.Drive rod slides in the left half section of chute of U-shaped chute, and slide cartridge rises along rotary shaft up and down for driving, upper and lower slide cartridge and friction
Ring is disengaged, and upper and lower slide cartridge is freely rotatable, synchronously, drive rod driving slide cartridge and rotary shaft rotation up and down.Drive rod is in U
To be slided in the half section of chute in the shape chute right side, slide cartridge declines along rotary shaft up and down for driving, synchronously, drive rod driving slide cartridge and rotation up and down
Rotating shaft rotates, and when drive rod departs from the tail end opening, upper and lower slide cartridge contacts again with drag ring, departs from the driving of U-shaped chute
Bar is oppressed on the top end face of upper and lower slide cartridge, slide cartridge above and below drag ring friction catch.
By above-mentioned design, the rotation of rotating cylinder, rotary shaft can be driven to rotate predetermined or fixed angle every time, for example,
Rotating cylinder rotates a circle, and the angle of rotary shaft rotation is less than one week, but the anglec of rotation of rotary shaft is fixed, or perhaps in advance
Fixed.In this way, rotating the certain angle of the rotating cylinder roughly, the accurate anglec of rotation of rotary shaft, the i.e. rotation of screw mandrel can obtain
Gyration is precision, and then, displacement of the laser along dragging track is accurate.
Rotary shaft is provided with radial flange, and regulation spring is provided between radial flange and the top end face of upper and lower slide cartridge, is adjusted
The bottom of section spring is pressed at the top of the slide cartridge up and down between U-shaped chute both ends open on end face, and the top for adjusting spring compresses
In set screw, set screw is screwed onto on radial flange.
As described above, the set screw is rotated, the deflection for adjusting spring is adjusted, and drive rod is driven on described
When lower slide cartridge rises, regulation spring is adjusted to the active force of the slide cartridge up and down, to avoid drive rod from only driving on described
Lower slide cartridge lifting is without driving it to rotate the generation of this extreme case.But main, the regulation spring is to described upper and lower
The active force of slide cartridge is adjusted, and the adjustable drive rod, which covers the U-shaped chute, can drive slide cartridge and the rotation up and down
The anglec of rotation of rotating shaft.
End face is provided with end face convex portion at the top of slide cartridge up and down between U-shaped chute both ends open, and the end face convex portion is located at U-shaped
Arcuate guide portion is provided with chute both ends open, drive rod is imported U-shaped chute by the arcuate guide portion.
As described above, drive rod is oppressed on the top end face of the upper and lower slide cartridge, driving before entrance U-shaped chute
Bar rotates with rotating cylinder, runs into the end face convex portion, under the guiding of the arcuate guide portion, into U-shaped chute.The regulation
The bottom of spring is pressed on the end face convex portion.The design of end face convex portion can ensure that drive rod enters U-shaped chute, effectively avoid
With the drive rod of rotating cylinder rotation the opening of U-shaped chute is crossed because rotating speed is too fast.
Regulation screw is opened up in the side wall of upper and lower slide cartridge, the regulation adjusts spiral shell with regulating bolt is bolted with screw
The top of bolt is provided with damping block, and damping block is pressed on the lateral wall of rotary shaft.Damping block is to the slide cartridge up and down and the rotation
Frictional force between rotating shaft is adjusted, to avoid drive rod from only driving the lifting of slide cartridge up and down without driving its rotation this
The generation of extreme case.But main, the frictional force up and down between slide cartridge and the rotary shaft is adjusted, adjustable
The anglec of rotation of slide cartridge and the rotary shaft up and down can be driven by saving the drive rod and covering the U-shaped chute.
