The utility model discloses a crossbeam foundation device for a gantry type numerical control cutting machine, comprising a foundation crossbeam (1), a linear guide rail (2), and a lifting machine fixing plate (4), the linear guide rail (2) is an integral linear guide rail, the two sides are provided with guide rods (3), and the lifting machine fixing plate (4) is cooperated with the guide rods (3) via a roller (6). The crossbeam foundation device, compared with a current crossbeam foundation device for a gantry type numerical control cutting machine, is advantaged by novel structure, rapid and accurate installation, high cutting precision, stable transmission, low noise, generation of good economic benefit, and guarantee of development of a high precision gantry type numerical control cutting device.

Description

A kind of numerical-controlled gantry cutting machine crossbeam base apparatus
Technical field
The utility model relates to a kind of machine tool component, particularly a kind of numerical-controlled gantry cutting machine basic components.
Background technology
Along with the development of modern mechanical processing industry, people improve constantly the requirement of cut quality, precision and the production efficiency of sheet material, so that cutting technique is able to fast development.But still there is more problem in existing numerical control cutting machine, mainly contain: the integrated costs such as (1) guider complex structure and purchase, installation, maintenance are high, this device adopts two square ball line slideways usually, makes the lifting body fixed head realize rectilinear motion by two slide blocks that are fixed on the line slideway; (2) line slideway assembling difficulty, complex procedures, be difficult to guarantee the depth of parallelism of linearity and two line slideways of single line slideway, in the line slideway process is installed, every line slideway all needs 22 ~ 25 screws to fix that (the screw number depends on the physical length of line slideway, screw number when this routine cut-off line rail length is 3.6m), want so that line slideway has certain linearity and the depth of parallelism, must guarantee on the crossbeam screwed hole point-blank and be parallel to each other, consider simultaneously the clearance fit relationship of each screw and line slideway, when tightening a screw, all need linearity and the depth of parallelism of alignment guide rail at every turn; (3) traditional numerical control cutting machine also has transmission not steady, cutting accuracy is low, noise is large, the defectives such as reliability is low, the assembly process that said structure determines has a significant impact linearity and the depth of parallelism of line slideway, thereby causes transmission not steady, creep, cutting accuracy is low, and produces a large amount of noises in this process, can directly destroy slide block in the serious situation.
In addition, the domestic present special industry standard for the numerical control cutting machine cutting accuracy that also do not have, temporary transient reference " thermal cutting plasma cut quality and dimensional discrepancy " is industry standard (JB/T10045.4-1999), and the cutting accuracy of this standard definition is 0.5mm.
Summary of the invention
The utility model mainly is the deficiency that exists in the existing numerical-controlled gantry cutting machine technology for solving: complex structure, and during installation fee, steadily noise is not large in transmission, and cutting accuracy is low.
The technical solution adopted in the utility model is: a kind of numerical-controlled gantry cutting machine crossbeam base apparatus, the basis crossbeam is provided with line slideway, the line slideway both sides are fixed with guide rod, and the lift fixed head rolls at line slideway by roller shaft and roller, and roller cooperates with guide rod.Wherein, traditional bilinear guide rail is changed into a monoblock type line slideway, be fixed on a side of basic crossbeam, guide rod is separately fixed at the both sides of line slideway, and roller rolls at guide rod.Line slideway aluminium alloy material, and the wide 2 ~ 3mm of width with the Width of basic crossbeam matching part basis crossbeam, roller is selected the GCr15 bearing steel, and the lift fixed head rolls at line slideway by roller shaft and roller, and roller quadrate on perpendicular is arranged.
The utility model adopts the monoblock type line slideway, it is easy for installation, registration, and the stable drive noise is low, linearity and the depth of parallelism obviously improve, line slideway adopts aluminum alloy materials, has improved linearity and the depth of parallelism, has reduced crossbeam weight, during for fear of the shake of basic crossbeam on the impact of line slideway, width widen 2 ~ 3mm line slideway guarantees its linearity and the depth of parallelism, improves the cutting accuracy of numerical control cutting machine; The lift fixed head adopts the roller type transmission, and the material of roller is the GCr15 bearing steel, and simple with traditional slide block type transmission structure compared, transmission is more steady, and is easy installation and reliable.
The utility model is compared with existing numerical-controlled gantry cutting machine crossbeam base apparatus, and novel structure is simple, installs fast accurately, cutting accuracy is high, the stable drive noise is low, can produce good economic benefit, for the development of high accuracy planer type numerical control cutting equipment provides guarantee.This design changes traditional bilinear guide rail into the monoblock type line slideway, its linearity and the depth of parallelism have direct impact to transmission stability and cutting accuracy, use linearity and the depth of parallelism that this monoblock type line slideway can better guarantee the crossbeam transmission, and assembly process is very easy, the staff only need guarantee line slideway apart from the distance of beam-end this line slideway " edge " on crossbeam, get final product by the screw of both sides is fixing, and its linearity and the depth of parallelism are determined by line slideway self fully.Pass through verification experimental verification: the numerical control cutting machine stable drive that adopts this to improve design is reliable, the generation of well having stopped creeping phenomenon; Its cutting accuracy is brought up to 0.2mm by original 0.5mm; The equipment running noises is reduced to the 58.6dB decibel by original 76.2dB's, has reduced by 76.9%, reaches the industrial area Standard of Environmental Noise of national regulation.Aspect economic benefit, although the price of a monoblock type line slideway is 2 times of original line slideway, from aspect analysis-by-synthesis such as installation cost input, later maintenance inputs, the monoblock type line slideway is more economical more efficient.
