Abstract

The utility model discloses a universal semi-automatic metal cutting machine which is the improved design of the existing semi-automatic cutting machine structure. A door shaped cutting frame is arranged on a vertical threaded rod extending from a driving device in the machine. The universal semi-automatic metal cutting machine is composed of two vertical shafts and a transverse shaft. The bottom end of the vertical shaft 1 is connected with the vertical threaded rod by a movable fit casing tube to cause the cutting frame to rotate around the vertical threaded rod. Thus the cutting position can be convenient adjusted. A vertical guideway, a transverse guideway and a cutting gun are arranged on the lower end of the vertical shaft 2. The vertical shafts and the transverse shaft are connected by a bevel gear set. The power in the machine can be led to the vertical shaft 2 to drive the cutting gun to do circular motion. The utility model can flexibly cut the circle with the diameter between 50 mm to 650 mm without installing accessories.

Description

Universal semi-automatic metal cutting machine

The utility model is to the sign an undertaking improvement design of structure of existing semi auto cutting machine.

Though existing semi auto cutting machine can be controlled height, angle, cutting speed of burning torch etc., automatic cutting straight line or great circle, but the burning torch position is difficult for regulating, can only be in fuselage one side cutting straight line, and burning torch and fuselage only about 200mm, all need dismounting walking track apart from adjustable extent during cutting straight line at every turn.The cutting bowlder needs radius rod to be installed earlier, to be decided pin, also need manage to decide pin during cutting, and it is very inconvenient to operate.The following circle of cutting φ 300mm because of cutting the influence that produces heat, is decided quite difficulty of pin, is difficult to practicality aborning, and the following roundlet of φ 100mm can't cut with it.

The purpose of this utility model is a structure of having improved existing semi auto cutting machine, has kept the over-all properties of former cutting machine, has increased new cutting function again.Improved structure can be adjusted the burning torch position flexibly, and burning torch all can be worked in each orientation all around of cutting machine; The design also can make burning torch carry out circular motion under the machine internally-powered drives, and need not dress and uses annex, can cut the circle of φ 60～650mm neatly.

The design has kept motor, deceleration transmission walking mechanism and the semiconductor stepless speed regulation control device of former cutting machine.In former cutting machine deceleration device, the upright screw rod of the lengthening that changes the outfit is extended to the body top, and door shape cutting rack is installed on it.Cutting rack is made up of two vertical pivots and a transverse axis.Vertical pivot 1 lower end links to each other with upright screw rod by sleeve pipe movingly, can rotate synchronously with upright screw rod.The one group of bevel gear in vertical pivot 1 upper end links to each other with transverse axis, and the transverse axis other end is passed to rotation vertically downward vertical pivot 2 again through another group bevel gear.Upright guide rail, cross rail and burning torch are installed in vertical pivot 2 lower ends.

The sleeve pipe movingly of vertical pivot 1 can rotate whole cutting rack around the upright screw rod that stretches out casing, selects cutting position around cutting machine arbitrarily.Fixed screw is arranged, fixedly cutting rack on the sleeve pipe.

Between vertical pivot 1 and transverse axis clutch is housed.When this clutch unclamped, transverse axis did not rotate, and motor can drive walking mechanism makes cutting machine by former working method cutting straight line or great circle.During this clutches engaged, with the throw-out-of clutch of walking mechanism driving wheel, cutting machine body maintains static.Vertical pivot 1 drives transverse axis through bevel gear and rotates, and transverse axis drives the vertical pivot 2 that upright guide rail, cross rail are housed through another group bevel gear again and rotates.Burning torch is contained in cross rail one end, rotates with vertical pivot 2 and makes circular motion, and the projection of vertical pivot center line is gives the circle of contact center of circle, adjusts the position of burning torch on cross rail, promptly adjusts and cuts the distance of chewing with the center of circle, can determine to give the circle of contact half warp, adjusting range 50～650mm.

The semiconductor control section of cutting machine can make the walking of cutting machine or the circular motion of burning torch realize stepless speed regulation.

Forward and reverse operation of cutting machine can make the walking of cutting machine forward-reverse, or makes burning torch against clockwise rotating.

Through upright guide rail handwheel, can adjust the burning torch height, control cut chew and cutting member between distance.

The burning torch angle can be adjusted in 45 ° of scopes, with bevel cut.

The utility model is compared with existing cutting machine, keeps that its structure is tightly played, light, inexpensive advantage and whole service behaviour, and newly-designed structure makes cutting rack rotatable, is easy to regulate the burning torch position.During cutting straight line, need not to move cutting machine or dismounting walking track, very easily change to opposite side and continue cutting from a side of cutting machine.Because cutting rack and cross rail arranged, burning torch and fuselage apart from maximum adjustable to 750mm.The cutting bowlder need not installation accessories, and radius is easy to regulate, and the center of circle is easy to determine, also need not in the cutting process to control again, can cut the circle of φ 50 to 650mm.In addition, cutting bowlder cutting machine body maintains static, and need not the smooth sheet material of large tracts of land and settles the cutting machine walking, can cut out the sheet material maximum inscribed circle, is beneficial to the use leftover pieces, radius rod is installed, is decided pin, still can be by former working method cutting great circle.

Accompanying drawing is the embodiment schematic diagram.6 is casing among the figure.Motor 8 is paid the driving wheel 5 of 3 drive walking mechanisms by the two-stage turbine in the transmission mechanism, and clutch 9 is housed therebetween.The door shape cutting rack of being made up of vertical pivot 1, transverse axis 7, vertical pivot 2 is housed on the upright screw rod 4.Vertical pivot 1 length is 180～250mm, and transverse axis 7 length are 340～420mm, and vertical pivot 2 length are 150～200mm.Perpendicular transverse axis all is equipped with sleeve pipe outward, plays protection and support effect.The sleeve pipe of the sleeve pipe of vertical pivot 1 and upright screw rod 4 can rotate vertical pivot 1 around upright screw rod 4 for joining movingly, changes the cutting rack position.Fixed screw on the sleeve pipe is cutting rack fixedly.Connect with bevel gear group 11,12 between the transverse axis vertical pivot, motor 8 power are reached vertical pivot 2.Upright guide rail 13, cross rail 15 are equipped with in vertical pivot 2 lower ends, upright guide rail 13 long 100～150mm, cross rail 15 long 250～350mm.Burning torch 16 is contained in an end of cross rail 15.Handwheel 14 can be regulated the burning torch height, and handwheel 16 can be regulated the distance between burning torch and the vertical pivot 2.

Clutch 10 unclamps, during clutch 9 engagement, transverse axis 7 does not rotate, motor 8 drives driving wheels 5.Like this, cutting machine just is being with the cutting rack walking, can be by former cutting machine working method cutting straight line or great circle.

Clutch 10 engagement, when clutch 9 unclamps, driving wheel 5 is motionless, cutting machine body maintains static.Vertical pivot 1 drives transverse axis 7 through bevel gear group 11, and transverse axis 7 drives vertical pivots 2 through bevel gear group 12, and that vertical pivot 2 drives is upright, cross rail and burning torch rotate.Burning torch 16 is made circular motion can cut circle, vertical pivot 2 center lines be projected as the center of circle, cut that to chew apart from the distance of vertical pivot 2 center lines be radius.Can cut the circle of φ 50 to 650mm.

Cutting speed, the adjusting of direction of travel, burning torch height, burning torch angle is identical with former cutting machine.

The utility model can combine with existing semi-automatic oxygen cutter, also can be used with existing air plasma cutter.
