Description
Technical field
The present invention relates to laser cutting technique field, especially a kind of laser nozzle attachment device.
Background technique
Currently, laser cutting is used as a kind of novel thermal cutting technology, have cutting speed fast, high production efficiency, cut end
The advantages that face is high-quality, and heat affected area is small and environmentally friendly has become one of main sheet metal cutting mode, has obtained more next
More it is widely applied.However, in actual use since irregular by cutting material, there are maloperation and other interference
The influence of object, therefore the damage for hitting to cause cutting head will be caused to laser cutting head at runtime.
There are mainly two types of common anticollision device, collision-prevention devices, and one is spring anticollision device, collision-prevention device, which is gun iron link, and when collision holds
The components easy to damage connecting with spring, need to often replace；Another kind is exactly to work as cutting head using simple magnetic anti-collision device
After being hit, cutting head can be completely disengaged with magnetic anti-collision device, and lower end workpiece, which is fallen, to be caused to damage, and needs manually install again
Debugging, while dust can also fall into cutting head, pollute focusing lens.And swashing in high voltage and high power is applied in this anticollision design
Light nozzle can be easy because cannot withstand high pressure gas and mistake stops working.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of laser nozzle attachment device.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of laser nozzle attachment device is used to install the capacitance sensor of laser cutting head including screw thread positioning body,
Ceramic insulation guard member made of brittle ceramic material is set with outside the screw thread positioning body, in the ceramic insulation guard member
It wears and is connected to conductive pin, be additionally provided with nut piece in the ceramic insulation guard member and connect with conductive pin.
As a preference, the conductive pin is made of red copper alloy material, and is additionally provided on conductive pin very golden
Coating.
As a preference, the screw thread positioning body and nut piece are made of brass material or stainless steel material.
As a preference, the conductive pin tail end is connect by screw thread with nut piece.
The beneficial effects of the present invention are: the cooperation conductive pin of the ceramic insulation guard member made of brittle ceramic material is set
Meter, both eliminate solve original technology cannot withstand high pressure gas cause conductive sheet fall off laser nozzle can not normal use disadvantage
End, while guaranteeing to shut down in time when laser nozzle encounters shock and protecting the element inside laser cutting head.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is perspective view of the invention.
Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The present invention is further elaborated.For the thorough explanation present invention, some certain details can be related in following description
Section.And in these no specific details, the invention can still be realized, i.e., the technical staff in fields uses herein
These describe and state that the others skilled in the art into fields can more effectively introduce their work essence.
Referring to Fig.1, a kind of laser nozzle attachment device is used to install the electricity of laser cutting head including screw thread positioning body 1
Hold sensor, is set with ceramic insulation guard member 2 made of brittle ceramic material, the ceramics outside the screw thread positioning body 1
It is worn on insulation protection part 2 and is connected to conductive pin 3, be additionally provided with nut piece 4 in the ceramic insulation guard member 2 and connect with conductive pin 3.
Ceramic insulation guard member 2 is both for installing the attachment device of laser nozzle, and effect is insulated with laser nozzle and surrounding metal, simultaneously
As rapid wear breakable member, the cutting head under high-speed cruising state is protected
When laser cutting head is in normal operating conditions, the capacitance sensor of laser cutting head is for detecting laser cutting head
Nozzle and workpiece distance, capacitance sensor is electrically connected with the power circuit of circuit board.Cutting head body is grounded by lathe, electric current
Detection circuit and circuit board communicate to connect, and current detection circuit is the power circuit power supply of circuit board.Ceramic insulation guard member 2
There are enough insulating properties, and conductive pin 3 connects weak current, guarantees that capacitance sensor has stable capacitance, just can ensure that laser
The stability of nozzle and cutting material height.
When the capacitance sensor side of laser cutting head and workpiece or lathe etc. collide, ceramic insulation guard member 2
It can be contacted with workpiece or lathe, since ceramic insulation guard member 2 connects power circuit by conductive pin 3, workpiece or lathe need
In ground state, therefore, shell can be shorted with workpiece or lathe, and current detection circuit can detecte curent change,
It can be learnt that side collision has occurred and shuts down rapidly, more serious side collision damage is avoided, safeguard protection is played
Effect.3 tail end of conductive pin is connect by screw thread with nut piece 4.
The frangible ceramics of the preferred brittleness of ceramic insulation guard member 2, guarantee its bear 200 kilograms shock can fragmentation, phase
Than conventional ceramic (shock that can bear 500 kilograms), safety is higher.High pure zirconia can be used in specific ceramic insulation guard member 2
Aluminium ceramic system is standby, and purity may be selectedSimilar ceramic material can also be selected according to laser cutting machine specific targets.
The conductive pin 3 is made of red copper alloy material, and true gold plate is additionally provided on conductive pin 3, be can be improved and is led
The electric conductivity of acusector 3.
The screw thread positioning body 1 and nut piece 4 are made of brass material or stainless steel material.
According to above-mentioned principle, the present invention can also be made appropriate changes and modifications to the above embodiments.Therefore, this hair
It is bright to be not limited to specific embodiment disclosed and described above, some modifications and changes of the invention should also be as to fall into this
In the scope of protection of the claims of invention.
