Description

Portable cantilevered mode digital control cutting machine

Technical field

The cutting processing equipment that a kind of cutting metal member is used.

Background technology

At present, cutting processing equipment mainly is to be main with the planer type numerical control cutting machine.Though this equipment cut coverage is big, processing performance is good, involve great expense, and floor space is big, needs fixedly auxiliary facility such as factory building and rane trolley, so one-time investment is big.

02223427.6 number utility model patent has proposed a kind of " portable numerical control gas cutting machine "; Characteristics be simple in structure, volume is little, in light weight, be easy to carry and cost low; Can cut the hardware of arbitrary shape, high efficiency, adaptation large-scale production, single-piece production and maintenance activity.But there is following weak point:

1, the deceleration device in the horizontal and vertical travel mechanism is a worm-and-wheel gear.The shortcoming of this mechanism is that the assembling link is many, easy to wear, causes the complete machine mobile accuracy low.

2, the roller on this machine has two functions: the one, walk in orbit, and the 2nd, guiding.For accurate guiding, the contact-making surface between roller and the track is male and fomale(M&F) often.In the long-term use, the contact-making surface on the roller is easy to wear and cause the gap to increase, and has a strong impact on and vertically moves precision.In addition, roller skids easily in orbit, and also influence vertically moves precision.

3, laterally move owing to having only a horizontal mobile rack bar band cutting torch, therefore laterally mobile accuracy and operation balance are all undesirable.

Summary of the invention

The purpose of the utility model provides a kind of portable cantilevered mode digital control cutting machine, accomplishes that mobile accuracy is high, balance is strong, reaches the same cut coverage of planer type numerical control cutting machine and machining accuracy.

The utility model comprises travelling car and numerical control device; Travelling car is located on the guide rail and supporting track parallel to each other through four rolling, and improvements are that the horizontal stepper motor top connects firmly horizontal planetary reducer, and laterally planetary reducer is installed in the frame plate slotted eye of upper rack; Frame is fixed on the little car bottom plate; The frame plate top connects firmly transverse support, is coated with the balance rack bar in the guide hole of half of front and back walls middle part, a transverse support left side, and the right one side of something of transverse support has been screwed horizontal saddle; Laterally be coated with horizontal mobile rack bar and laterally steering bar respectively in the upper and lower guide hole of saddle; Laterally be fixedly connected with transverse drive shaft on the planetary reducer output shaft, duplicate gear is housed on the transverse drive shaft, the upper and lower gear of duplicate gear meshes with horizontal mobile rack bar, balance rack bar respectively.Laterally mobile rack bar and laterally steering bar front end are fixed with the cutting torch bearing; The lifter rack bar that setting is arranged on the cutting torch bearing; Lifting motor is fixed on the cutting torch bearing, and the engagement of helical gear and lifter rack bar is arranged on the lifting motor main shaft, and hold-down support is equipped with in lifter rack bar lower end; Cutting torch connects firmly on hold-down support through the adjustable holder of tape insulation cover, on the cutting torch bearing igniter is housed.Vertically the stepper motor below connects firmly vertical planetary reducer, and vertically planetary reducer is installed in the slotted eye of support and little car bottom plate, and the tooth bar engagement on vertical gear and the guide rail is vertically arranged on the planetary reducer output shaft.All there is nutted guide wheel shaft and the eccentric guide wheel axle that is distributed in the guide rail both sides at dolly base plate two ends, on guide wheel shaft and the eccentric guide wheel axle directive wheel that is close on guide rail are housed all.

Laterally shifting principle is following: when numerical control device sends horizontal move; Drive the rotation of horizontal planetary reducer and duplicate gear; Duplicate gear drives horizontal mobile rack bar and the balance rack bar carries out laterally moving simultaneously in the opposite direction; The outer cantilever of travelling car that stretches out that the cutting torch bearing laterally is housed on the mobile rack bar stretches out the outer mutual balance of balance rack bar of travelling car with rightabout all the time; Thereby keep travelling car not rock, balance is good, does not influence the precision of transverse cuts.When long term wear makes between horizontal mobile rack bar and the linkage gear gap increase, can unclamp the installation screw, the installation site of adjusting horizontal saddle makes gap smaller, thereby keeps mobile accuracy and prolong complete machine service life.

It is following to vertically move principle: vertically move when instruction when numerical control device sends; Vertically stepper motor rotation; The vertical gear pure rolling on the tooth bar of guide rail that drives on vertical planetary reducer output shaft is advanced, and vertically moves along guide rail thereby drive travelling car.At this moment, because two pairs of directive wheels are tightly clamped guiding rail, guarantee that travelling car vertically moves the direction non-migration.If long term wear makes between directive wheel and the guide rail when gapped, can adjust the installation site of eccentric guide wheel axle, be adjacent on guide rail all the time to keep directive wheel.

It is vertically upper and lower mobile that the lifting motor of the utility model drives the lifter rack bar through helical gear, can adjust the cutting torch height automatically.

Compared with present technology, the utility model has following characteristics:

1, owing to adopt the high accuracy planetary reducer, therefore simplifies the assembling link, improved mobile accuracy and cutting processing precision as deceleration device.

2, because duplicate gear makes horizontal mobile rack bar and balance rack bar carry out opposite laterally moving simultaneously, therefore realize the dynamic equilibrium of laterally moving, further improved horizontal mobile accuracy.

3, because travelling car carries out pure rolling through the rack-and-pinion engagement system on guide rail, no skidding adds the no gap guiding of two pairs of directive wheels, so it is very high to vertically move precision, can match in excellence or beauty with the planer type numerical control cutting machine.

4,, therefore prolonged the service life of complete machine owing to adjustable gaps between rack and pinion, directive wheel and the guide rail.

In a word, the utility model mobile accuracy is high, and laterally shifting balance property is good, vertically move to be pure rolling, no gap guiding, so the cutting processing precision is good, can match in excellence or beauty with the planer type numerical control cutting machine, and installs, carries easily, long service life.
