Description

The trolley type numerical control cutting machine

A kind of equipment that cuts steel component of technical field, the particularly cutting mechanics of band numerical control device.

The existing planer type numerical control cutting machine of background technology cut coverage is big, cutting width can reach 4～6 meters, length can reach more than 10 meters, processing performance is good, but it is bulky, involves great expense, every need 40～800,000 yuan, and floor space is big, needs fixedly auxiliary facility such as factory building and rane trolley, so one-time investment is big.Existing trolley type cutting machine does not have the numerical control device, and function singleness can only be carried out straight cuts, just can carry out the cutting of φ circular pieces more than 200 millimeters after adding accessory.

The summary of the invention the purpose of this utility model provides a kind of trolley type numerical control cutting machine, accomplishes to cut in the certain width scope member of size, shape arbitrarily, and volume is little, cost is low, and convenient in carrying can be in the open and field work.

Technical scheme is as follows: main engine bed is the dolly shape, is seated on the light guide rail by driving wheel and scroll wheel, and light guide rail surface has been rolled anti-skid design.Gas path device is housed in the main engine bed, and the computer of band special-purpose software control program is by vertical stepper motor and horizontal stepper motor in interface board connection and the main control system seat.Vertically stepper motor reaches by worm gear pairs and squeezes with the driving wheel on the formula clutch driving main engine bed at vertical light-duty guide rail top offset.Horizontal stepper motor drives horizontal carrier wheel by worm gear pairs, and laterally carrier wheel drives the horizontal rack bar displacement that is engaged with, and laterally on the rack bar cutting torch is housed.In order to guarantee that horizontal rack bar stretches out the indeformable and raising job stability of the outer part of machine, 1～3 and rack bar parallel guide rod are installed, guide rod is installed on the support by linear bearing, and the baffle plate at two ends connects into rectangular-shaped frame frame shape with rack bar and guide rod, to guarantee the accuracy of cutting torch work.In addition, laterally be fixed with the balance travelling gear on the same vertical shaft of carrier wheel, the balance rack bar is engaged with, and balance iron is housed on the balance rack bar.When horizontal rack bar moves, the reverse displacement of balance rack bar, the balance iron on it plays balanced action to cutting torch.Shared horizontal space is unlikely too big when making machine works, and the designing requirement of balance travelling gear and balance iron counterweight is that the displacement of balance rack bar is 1/3～1/2 of horizontal rack bar displacement.

Cutting torch of the present utility model can replace with the plasma burning torch, carries out the plasma cutting.

Compared with the prior art, the utility model has following characteristics:

1, simple in structure, volume is little, in light weight, convenient in carrying and cost are low.

Because vertically stepper motor is by the driving wheel displacement on worm gear pairs and the crowded expanding clutch driving main engine bed, horizontal stepper motor drives the horizontal rack bar displacement that cutting torch is housed by worm gear pairs and horizontal carrier wheel, some middle transmission links have all been omitted than existing various numerical control cutting machines, therefore drive mechanism is simple, can alleviate the complete machine weight and volume, be convenient to carrying, and simple in structure, make easily, cost reduces.

2, high efficiency can be cut the member of arbitrary shape in the certain width scope.

Two groups of driving mechanisms of vertical and horizontal can divide into groups to work alone and work simultaneously.When grouping worked alone, cutting torch can vertically done unlimited rectilinear motion, can do rectilinear motion in horizontal 1.5 meters left and right sides width ranges.When the while co-ordination, cutting torch can be realized the two-way simultaneous walking, thereby can cut the member of arbitrary shape in 1.5 meters left and right sides width ranges, adapts to large-scale production, single-piece production, and the field maintenance operation in the open.

3, good, the accurate positioning of stable working, cutting accuracy are higher.

On the crossfeed direction, owing to adopt by linear bearing and be installed in the displacement that guide rod on the support guides horizontal rack bar, add the stabilization of the rectangular frame that forms between top guide bar and the rack bar and the stabilization of balance iron, can guarantee the smooth working state of cutting torch, therefore stable working is good, accurate positioning, the cutting accuracy height.On the longitudinal feed direction, because vertical light guide rail surface has been rolled anti-skid design, can prevent that driving wheel from skidding, therefore work is more reliable.

4, can carry out the plasma cutting.

5, avoid the injury of radiation to human body.

Owing to can realize stepless adjustment and far distance controlled, therefore can avoid the injury of radiation to greatest extent to human body.
