Description

A kind of laser cutting machine bed

Technical field

The present invention relates to laser cutting machine correlative technology field, particularly relate to a kind of can collection cut flat board and pipe, gantry-type laser cutting machine.

Background technology

Existing laser cutting machine, major part is all the cutting flat board of simple function, or the cutting pipe of simple function；Small part can working flat plate and pipe laser cutting machine, being structurally characterized in that of employing, split design principle, independent secondary lathe bed with stretch out the significant component of cantilever beam of main lathe bed.

In the market can with machine cut flat board and pipe laser cutting machine, secondary lathe bed is mostly adopted to be separately set in the outside side of main lathe bed, pipe placed by secondary lathe bed, and when cutting pipe, if required precision is higher, when workpiece is complex with the conversion of laser head relative position, the laser cutting machine of this kind of design, owing to the depth of parallelism of secondary bed ways and main bed ways cannot be ensured, and the design of cantilever beam, relative inertness is big, and bigger moment of torsion can cause that beam deformation is bigger；Therefore above-mentioned design is difficult to meet its requirement on machining accuracy；And the design of cantilever beam, not readily transportable.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of laser cutting machine bed.When solving same machine cutting flat board with pipe, it is necessary to external independent secondary lathe bed, and the structure of cantilever beam need to be designed；And easily occurring that header portion deformation is difficult to control to, machining accuracy is not enough, and cutting speed reduces, transport inconvenience, the problem increasing production cost.

The technical solution adopted in the present invention is: adopt a kind of laser cutting machine bed, and lathe bed main body is formed by standard rectangular pipe and the connection of standard square tube；In two parallel square tubes in outside, coupling and have longer boss, for installing guide rail and tooth bar after polish, guide rail is used for laying crossbeam herein；In two parallel square tubes of lathe bed lower inside, coupling and have shorter boss, for installing guide rail after polish, guide rail is used for laying the circular tube support frame that can slide herein；There is electric machine support at lathe bed rear portion, and place the panel beating case of laser instrument；Two parallel square tubes that in the middle part of lathe bed, top is shorter, for laying the platform at workpiece to be machined place.

Compared with prior art, the invention has the beneficial effects as follows: 1, the secondary lathe bed of held circular pipe and main lathe bed are integrated, eliminate the design of cantilever beam, during beam motion state conversion, inertia is relatively small, and lathe bed stress is more uniform, header portion deflection is greatly lowered, so its machining accuracy is high, reliability is high, good stability；2, the design of laser cutting machine bed of the present invention, is provided with fork truck bracing frame bottom lathe bed；Top is provided with lifting bolt hole, and has coupled boss so that it is stress evenly, reduces lifting deformation；It is convenient in factory and moves lathe bed；3, the design of laser cutting machine bed of the present invention, internal structure is compact and reasonable, and floor space designs compared to split, little by general 1/3rd, convenient transportation, is conducive to plant area to produce the division in region.

Accompanying drawing explanation

Fig. 1 is the example structure schematic diagram of this laser cutting machine bed.

In figure: 1 hole for hoist part, 2Y to square tube, 3 long boss, 4 platform beams, 5 short boss,

6 pipe fixtures support beams, 7 motor bearing seats, 8 panel beating casees, 9 pedestals, 10Z to support column, 11 fork truck bracing frames,

12 operating board bracing frames, 13X to rectangular tube, 14 rectangular openings.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described, and exemplary embodiment therein and explanation are only used for explaining the present invention, but not as a limitation of the invention.

As it is shown in figure 1, a kind of laser cutting machine bed, the 2Y in its structure is linked together the main part of composition lathe bed to support column and 13X to rectangular tube to square tube, 4 platform beams, 6 pipe fixtures support beams, 10Z.

1 described hole for hoist part, is by, shown in Fig. 1, being connected in two 2Y on the four of square tube end positions, the centre position of 1 hole for hoist part, is drilling screwed hole, when needs handling the machine, it is screwed into threaded hook, coordinates flexible steel wire, sling with ground jack；11 described fork truck bracing frames, are two short square tubes are connected in 6 pipe fixtures support beam lower surface, when the crane inconvenience used, use fork truck to be held up, and short distance is transported.

3 described long boss, shown in Fig. 1, are connected in 2Y to square tube upper surface, and 3 long boss are after milling herein, install guide rail and tooth bar, then will be equipped with the header portion of laser head and servomotor, mounted thereon.This header portion is not belonging to lathe bed main body；5 described short boss, are be connected in 6 pipe fixtures to support the upper surface of beams, and 5 short boss are after milling herein, install guide rail, then the fixture that is used for supporting pipe is mounted thereon, and this fixture is not belonging to lathe bed main body；The milling operation of 3 long boss and 5 short boss completes at an in-process, once ensure that assembly precision.

4 described platform crossbeams, shown in Fig. 1, it is possible to according to the platform size to lay, select its quantity, and the present embodiment is to have selected three, and wherein two are positioned at top, for supporting the platform laying flat-type workpiece；Also have one and be positioned at lathe bed bottom, support the following faces of beam with 6 pipe fixtures and contact and couple, and contact to support column with the 10Z of lathe bed middle part and couple；Support beam for supporting 6 pipe fixtures, reduce by 6 pipe fixtures with this and support the deflection of beam.
