Two laser beam expanding lens are designed, one of beam expanding lens is designed to the structure that can be shifted one's position, when the big laser hair of needs
When dissipating angle, this laser beam expanding lens is removed into optical path, laser beam expanding lens are moved into laser light when needing small laser beam divergence
Road, simple laser beam expanding lens transposition mechanism are determined using the combination of the round seam allowance and positioning pin of laser beam expanding lens pedestal
The position of beam expanding lens makes the laser beam expanding lens optical axis of beam expanding lens and laser transmitting system optical axis weight when moving into laser transmitting system
The advantages of conjunction, this interchanging method is that structure is simple, but the positioning accuracy of beam expanding lens is by the size of round seam allowance and positioning pin essence
Degree limitation, positioning accuracy is lower, while most of inversion mechanism can only realize a kind of beam expanding lens transposition of specification.
Summary of the invention
In order to overcome the shortcomings of that prior art, the present invention provide a kind of laser beam expanding lens transposition mechanism, can be realized
The function of accurate positioning and more expanding locations.
The technical solution adopted by the present invention to solve the technical problems is: a kind of laser beam expanding lens transposition mechanism, including base
Seat, the pedestal top are equipped with buffer plate, and pedestal left side both ends are longitudinally provided with the sliding rail of cuboid, the cunning
There is lead screw by threaded engagement inside rail, stepper motor is installed, the stepper motor passes through company at the top of the buffer plate
Axis device is connected with transposition plate, and spline connection type is used between the shaft joint and transposition plate, and the main shaft of the shaft joint is horizontal
It is connected with discoid reel fixing piece to transposition plate is passed through, the reel fixing piece is fixed by screws in the right side of transposition plate
Face, the front and back side of the transposition plate are provided with trapezoidal expansion mirror fitting groove, and the two sides cell wall for expanding mirror fitting groove is arc
Concave edge, it is described expand mirror fitting groove two sides be provided with side regulating tank, the side regulating tank is internally provided with hydraulic buckling screw.
As a preferred technical solution of the present invention, the pedestal and sliding rail junction have been internally integrated feed screw nut
Auxiliary structure.
As a preferred technical solution of the present invention, the lead screw passes through the motor driven of laser beam expanding mechanism.
As a preferred technical solution of the present invention, the buffer plate uses plasticized polyurethane flitch.
As a preferred technical solution of the present invention, the stepper motor is provided with frequency converter and retarder.
As a preferred technical solution of the present invention, the diameter of the transposition plate is greater than the peace of stepper motor and pedestal
Fill size.
Compared with prior art, the beneficial effects of the present invention are: it is whole by the longitudinal sliding rail of setting and lead screw driving, from
And avoid in laterally linear motion, expanding vibration and gravity of the mirror by motor is influenced, the inaccuracy of resetting is caused,
The vibration of lead screw transmission is offset by gravity in longitudinally disposed guide rail, thus it is more accurate when being positioned, and reduce
The number of resetting drives transposition plate by setting stepper motor, the positioning for expanding mirror is realized, so as to accurately realize expansion
Mirror increases the installation position for expanding mirror, to improve the multi-level use for expanding mirror, makes in longitudinal consistent phase by the way that transposition plate is arranged
Mirror effect must be expanded to reach most preferably, while by hydraulic buckling screw, can be good at mounting and dismounting expansion mirror.
