Description
Technical field
The present invention relates to plasma cutting, particularly a kind of servo-actuated protection mechanism of cutting gun of cutter nozzle.
Background technology
Plasma cutting is to utilize the heat of high-temperature plasma electric arc to make metal part or the office of workpiece incisionPortion's fusing (and evaporation), and get rid of motlten metal to form one of otch by means of the isoionic momentum of high speedPlant processing method. Its use does not need the auxiliary appliances such as compressor, transformer, gas cylinder, relatively light;And be furnished with singly takeing on and wrap of welder, be convenient for carrying; Cutting speed is fast, and precision is high; Cut young, neat,Without slag-off phenomenon. So be cutting mode conventional in steel tube cutting machine tool.
According to working condition requirement, use plasma cutting, between its cutting gun nozzle and workpiece, distance should be adjustedTo 3～8mm, but due to the cylindricity of work piece itself with to cross the swing that produces in machining long workpieces rotation etc. formerCause, work piece often surmounts setpoint distance, burning torch is produced to touching and even clash into, and has caused burning torch mistakeFast damage. And in process, work piece outside dimension be everlasting φ 297mm～φ 425mm itBetween change, each time change all in requisition for readjusting position, very loaded down with trivial details, affect operating efficiency.
At present, those skilled in the art have designed multiple structure or the device that can be used for burning torch protection, as inState patent CN203304765U, CN203304763U, although related to torch cutting follow and turned toFollow rifle headstock and protect cutting torch or burning torch, but still deposit in the time of the processing location for different size workpieceThere is deficiency.
Summary of the invention
For above-mentioned existing problems, the present invention aims to provide a kind of process for different size workpieceThe middle servo-actuated protection mechanism of can locate fast and can protect burning torch nozzle.
The present invention realizes by following technical proposals: the servo-actuated protection mechanism of a kind of burning torch nozzle, comprises and cuttingGun carriage, abutment sleeve, back-moving spring, the servo support being formed by sleeve pipe and semicircle buckle closure, buckle closure,Support wheel; Described abutment sleeve is fixed on described burning torch support, and its front end is drilled with screwed hole, and hole is in-builtThere is dog screw; Described servo support casing pipe sleeve is on burning torch and insert in described abutment sleeve, described fixedPosition sleeve can slide axially along described servo support sleeve pipe, described servo support sleeve pipe afterbody attacked screw thread withSetting circle nut coordinates; Described back-moving spring is enclosed within on described servo support sleeve pipe, its rear end and described fixedPosition sleeve end face is conflicted, and its front end and described servo support semicircle buckle closure end face are conflicted; Described support wheel is logicalCross baffle plate and bearing pin is hinged, can freely rotate around bearing pin; Described support wheel and buckle closure and described servo supportSemicircle buckle closure links together.
For ensureing the rotation life-span of described support wheel and bearing pin, as preferably, described support wheel inner ring is embedded withCopper sheathing.
For ensureing axiality and the weld strength of described pipe box and semicircle buckle closure, as preferably, described servo-actuatedSupport semicircle buckle closure and pipe box link have seam.
Adjustable for ensureing the distance between described support wheel and work piece, as preferably, described servo supportSleeve pipe front portion radial and axial is milled with a pair of orthogonal arc groove hole.
Advantage of the present invention is: simple and compact for structure; Burning torch is enclosed within the sleeve pipe of servo support, by buckle closureFix with the semicircle buckle closure of servo support, set the distance of support wheel and burning torch nozzle, ensureing complete cuttingUnder the state cutting, farthest protect the safety of burning torch nozzle; The flexible buffer of back-moving spring has preventedThe rigid shock of support wheel and workpiece Contact; The combination of dog screw and back-moving spring, has avoided machineThe accidental shock of structure.

Detailed description of the invention
Referring to Fig. 1, the present invention includes the burning torch support that formed by pressing plate I 1, intermediate plate 2 and pressing plate II 4,Servo support 6, abutment sleeve 17, back-moving spring 7, baffle plate 13, buckle closure 15, support wheel 9, bearing pin10, copper sheathing 11 etc. Abutment sleeve 17 is fixed on burning torch support, and its front end is opened in screwed hole and is equipped withDog screw 5, servo support 6 is made up of sleeve pipe and semicircle buckle closure, and its sleeve portion is enclosed within on burning torch, andInsert in abutment sleeve 17, sleeve pipe afterbody has been attacked screw thread, and setting circle nut 3 is housed on screw thread. Reset bulletSpring 7 one end are placed in abutment sleeve 17 one end, and the other end contacts with semicircle buckle closure one end of servo support 6.
Referring to Fig. 2, the support wheel 9 that is embedded with copper sheathing 11 is hinged by baffle plate 13 and bearing pin 10, bearing pin withBaffle plate junction is provided with nut 12, be arranged on support wheel on baffle plate 13 9 by baffle plate bolt 14 withThe semicircle buckle closure of moving support 6 links together, and buckle closure 15 is by buckle closure bolt 8 and half of servo support 6Round buckle lid links together.
Before work starts, distance to the plasma of adjusting between burning torch nozzle tip and support wheel 9 cutsOptimum Cutting distance, fixing. Adjust burning torch support, make support wheel 9 outer surfaces and work piece appearanceBetween face, to the state contacting and do not stress, support wheel can freely rotate around bearing pin.
After work starts, because the axiality of workpiece self is poor and the reason such as the amount of deflection of machining long workpieces, workPart outer wall and support wheel 9 are taken turns between wall can form contact force, and this contact force can force support wheel 9, bearing pin10, copper sheathing 11 moves and follows moment rigid shock to burning torch holder orientation together with baffle plate 13. ResetAbsorb impact and offset distance spring flexible, and made support wheel follow all the time work piece contact to existTogether. Under the prerequisite of effective cutting distance that ensures plasma cutting gun, effectively ensure burning torch nozzleSafety.
While variation between work piece diameter is by φ 297mm～φ 425mm, due to the existence of back-moving spring,Distance between this mechanism's meeting soft readjustment abutment sleeve 17 and baffle plate 13, makes this mechanism in similar cuttingThe scope of application in machine increases greatly.
