A kind of servo-actuated cutting headTechnical field
The utility model belongs to electronic cutting head field, especially relates to a kind of servo-actuated cutting head.
Background technology
Existing laser head mainly contains two kinds, and the first is Purely mechanical, it is reflector mount, and centre is lens barrel, and here is nozzle.Lens barrel is placed in lens barrel cover, can manually to upgrade lens barrel, then with an eyebolt or jackscrew locking lens barrel, make like this to need to focus during the material of its process different-thickness, but such design exists certain defect, it can only regulate focal length before machine operation, automatically focuses in can not working, if so the material out-of-flatness of cutting, that just can not carry out the work of cutting or carving.
The second is old-fashioned trailing type laser head, drives screw mandrel and line slideway motion by stepper motor, then drives laser lens barrel to realize moving up and down.The advantage of this laser head is the distance by inductive material and laser head in work, motor automatic lifting, thus automatically focuses.But it is large that its shortcoming is volume, inconvenient during installation, and cost of manufacture is high, manufactures and installation process complexity.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of servo-actuated cutting head, is especially applicable to cutting accurately sheet material and carving.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of servo-actuated cutting head, comprise lens barrel external member, side bottom lens barrel external member is fixedly connected with a motor plate, lens barrel external member is provided with a reflector mount, lens barrel is provided with in lens barrel external member, lens barrel slides in lens barrel external member, motor plate upper surface is provided with motor, the output of motor is provided with screw mandrel, screw mandrel top is through described motor and screw mandrel top is provided with nut, in the part that screw mandrel exceeds motor, cover has spring, the free end of screw mandrel is fixedly connected with a plate, the free end of lens barrel is through described connecting plate, and the bottom of lens barrel free end is provided with nozzle, connecting plate is arranged with two optical axises, bearing is provided with in lens barrel external member sidewall, two optical axises insert in the bearing of the sidewall of lens barrel external member, lens barrel external member side is provided with some fixing holes, the sidewall of connecting plate near nozzle side is provided with a laser sensor connecting plate, laser sensor connecting plate bends obliquely, and the below on its inclined-plane is provided with a laser sensor.Nozzle is laser nozzle or capacitance type sensor nozzle.Motor adopts through linear stepping motor, the similar cylinder moving of its motion mode.
In use, lens barrel external member is installed on the mobile apparatus by fixing hole by user, and then in its course of work, lens barrel moves up and down along with motor, and now two optical axises play stabilization.Screw mandrel in motor, the nut in upper end pins, screw mandrel overcoat spring, and spring, along with the motion of screw mandrel, plays the effect of stretching, contributes to screw mandrel straight line and motion stably.When lens barrel moves up and down, top and the bottom can mounting limit switch, ensures that lens barrel moves within the limits prescribed.The screw mandrel of motor moves up and down, and drives optical axis and the upper and lower rectilinear motion of lens barrel simultaneously.
On lens barrel connecting plate, a laser sensor is installed, can test nozzles laser spots out and the distance of sheet material automatically, thus realize engraving when cutting, motor automatic lifting, the effect of automatically focusing.
If laser nozzle is changed into capacitance type sensor nozzle, can when cutting metal material, the distance of induction nozzle and material automatically, thus motor automatic lifting, focus automatically.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, equipment is made to become convenient and accurate to the cutting of sheet material and engraving, it can testing laser nozzle laser spots out and the distance of sheet material automatically, thus when realizing engraving cutting, motor automatic lifting, the effect of automatically focusing; And the utility model has structure simply, easy to maintenance, processing cost is low, production efficiency advantages of higher.

Detailed description of the invention
As shown in the figures 1 and 2, the utility model is a kind of servo-actuated cutting head, comprise lens barrel external member 1, side bottom lens barrel external member 1 is fixedly connected with a motor plate 9, lens barrel external member 1 is provided with a reflector mount 3, lens barrel 4 is provided with in lens barrel external member 1, lens barrel 4 slides in lens barrel external member 1, motor plate 9 upper surface is provided with motor 2, the output of motor 2 is provided with screw mandrel 6, screw mandrel 6 top is through described motor 2 and screw mandrel 6 top is provided with nut 11, in the part that screw mandrel 6 exceeds motor 2, cover has spring 12, the free end of screw mandrel 6 is fixedly connected with a plate 7, the free end of lens barrel 4 is through described connecting plate 7, and the bottom of lens barrel 4 free end is provided with nozzle 8, connecting plate 7 is arranged with two optical axises 5, bearing is provided with in lens barrel external member 1 sidewall, two optical axises 5 insert in the bearing of the sidewall of lens barrel external member 1, lens barrel external member 1 side is provided with some fixing holes 10, the sidewall of connecting plate 7 near nozzle 8 side is provided with a laser sensor connecting plate 13, laser sensor connecting plate 13 bends obliquely, and the below on its inclined-plane is provided with a laser sensor 14.Nozzle 8 is laser nozzle or capacitance type sensor nozzle.Motor 2 adopts through linear stepping motor.
In use, lens barrel external member 1 is installed on the mobile apparatus by fixing hole 10 by user, and then in its course of work, lens barrel 4 moves up and down along with motor 2, and now two optical axises 5 play stabilization.Screw mandrel 6 in motor 2, the nut in upper end pins, screw mandrel 6 overcoat spring, and spring, along with the motion of screw mandrel 6, plays the effect of stretching, contributes to screw mandrel 6 straight line and motion stably.When lens barrel 4 moves up and down, top and the bottom can mounting limit switch, ensures that lens barrel 4 moves within the limits prescribed.The screw mandrel 6 of motor 2 moves up and down, and drives optical axis 5 and lens barrel about 4 rectilinear motion simultaneously.
On lens barrel 4 connecting plate, a laser sensor is installed, can test nozzles 8 laser spots out and the distance of sheet material automatically, thus realize engraving when cutting, motor 2 automatic lifting, the effect of automatically focusing.
If laser nozzle is changed into capacitance type sensor nozzle, can when cutting metal material, the distance of induction nozzle and material automatically, thus motor 2 automatic lifting, focus automatically.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
