Abstract
The invention relates to spindle box mechanisms of two numerical control engraving and milling machines, belonging to the field of numerical control machine tools. The structures of two spindle box mechanisms are simple, and the assembly precision of spindles can be guaranteed. More important it is convenient for adjusting the verticality of the spindles and a workbench. The spindle box mechanism mainly comprises a spindle box, a sliding plate and an electrical spindle with a flange in appearance (electrical spindle 1). When the spindle box mechanism is assembled, the electrical spindle 1 is firstly fixed in the spindle box so as to finish the assembly of a spindle box component 1; and then the spindle box component 1 is mounted on the sliding plate so as to finish the assembly of the spindle box mechanism 1. The spindle box mechanism 2 mainly comprises a spindle base, a spindle base gasket, a spindle base cover, a sliding plate and an electrical spindle without flange in appearance (electrical spindle 2). The electrical spindle 2 is mounted on an assembly body composed of the spindle base, the spindle base gasket and the spindle base cover to be assembled to be the spindle box component 2; then the spindle box component 2 is mounted on the sliding plate so as to finish the assembly of the spindle box mechanism 2. If the verticality of the spindles and the workbench is needed to adjusted, the spindle box component 1 or the spindle box component 2 is disassembled from the sliding plate, and the surface of the sliding plate matching with the spindle box or the spindle base cover is scraped. Through the invention, the mounting precision of the spindle and the accuracy of motion transmission can be guaranteed; the verticality between the spindle and the worktable surface is conveniently and quickly adjusted; and the processing precision and the processing efficiency are enhanced.
Description
Technical field
The invention belongs to Digit Control Machine Tool field, particularly relate to a kind of spindle box mechanism of numerical controlled engraving and milling device.
Background technology
Numerical controlled engraving and milling device is a kind of Digit Control Machine Tool that simultaneously possesses engraving and Milling Process ability, and its principal character is to use little cutter and high-speed electric main shaft to carve milling processing.This lathe of machining center comes out soon, just has people's statement into question in machine industry, and the function of machining center is too complete, and that uses processes small sized product high cost; In order to process small sized product, more than the main shaft of machining center generally all requires to reach 20000r/min, not only give to manufacture and design and bring sizable difficulty, also make use cost too high.Afterwards, people expected, the function of processing small sized product should be separated from machining center, formed a kind of new lathe kind, and numerical controlled engraving and milling device just arises at the historic moment thus.
The working speed of the electric main shaft that numerical controlled engraving and milling device is used, generally at 20000～60000r/min, more than reaching as high as 100000r/min, and requires electric main shaft smooth running when running light, and actual speed deviation must guarantee in 10%.In dry run process, the temperature at electric mainshaft bearing place and temperature rise all should be controlled at lower scope.Because numerical controlled engraving and milling device is mainly used in processing small sized product, in reality processing, the cutting load of electric main shaft is little, and the power of the dynamo-electric main shaft of numerical control engraving and milling is less, generally only has several kilowatts, than machining center main shaft, easily realize high rotating speed, can meet preferably needs high-speed, high-accuracy processing.
The distinguishing feature of numerical controlled engraving and milling device is exactly that the speed of mainshaft is high, and this just requires the installation accuracy of main shaft to want enough high.And the electric main shaft of most of carving milling machine is mounted on the assembly of main shaft flap and slide plate composition at present, there is no the mechanism of specially electric main shaft being installed, the mated condition of slide plate and main shaft flap as shown in Figure 1, obviously, the electric main shaft of carving milling machine is arranged on the installation accuracy that is difficult to guarantee electric main shaft on the assembly that both form, when the geometric accuracy of lathe is tested, if the perpendicularity of main shaft and work top is undesirable, surpassed tolerance, slide plate must be pulled down, Z axis slide block installation base on scraping slide plate chair, or slide plate chair is pulled down from portal frame, X-axis slide block installation base on scraping slide plate chair, if these two kinds of methods all can not be improved the perpendicularity of main shaft and work top, just portal frame must be disassembled from lathe bed, portal frame installation base on scraping lathe bed.Obviously operate so very inconvenient, installation time is increased greatly, so must modify the mounting means of main shaft.
At present, the contour structures of electric main shaft mainly contains two kinds: the structural representation of the flanged (FLGD) electric main shaft one of profile and two, two kinds of electric main shafts of the not flanged (FLGD) electric main shaft of profile is respectively as shown in accompanying drawing 2 and accompanying drawing 3, and the mounting means of obvious two kinds of electric main shafts is not identical.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art part, electric main axle structure for existing two types, provide respectively a kind of simple in structure, can guarantee the installation accuracy of main shaft, and be convenient to adjust the novel spindle box mechanism of the perpendicularity of main shaft and work top.
The technical solution adopted for the present invention to solve the technical problems is: for the flanged (FLGD) electric main axle structure of profile (as shown in Figure 2), design numerical controlled engraving and milling device spindle box mechanism one (being called for short mechanism one), mainly comprises the flanged (FLGD) electric main shaft one of main spindle box, slide plate and profile; For the not flanged (FLGD) electric main axle structure of profile (as shown in Figure 3), design spindle box mechanism two (being called for short mechanism two), mainly comprises the not flanged (FLGD) electric main shaft two of spindle drum, spindle drum pad, main shaft flap, slide plate and profile.
In described spindle box mechanism one, main spindle box mainly comprises main spindle box axis hole and main spindle box ear seat.Electric main shaft one is mounted in main spindle box axis hole, forms one (as shown in Figure 5) of main spindle box assembly, utilize ear seat that main spindle box assembly one is installed on slide plate, form spindle box mechanism one; Described spindle box mechanism two, for electric main shaft two designs, mainly comprises spindle drum, spindle drum pad, main shaft flap, slide plate.Electric main shaft two is arranged between spindle drum, spindle drum pad, main shaft flap, forms two (as shown in Figure 9) of main spindle box assembly, then main spindle box assembly two is assembled on slide plate, form spindle box mechanism two.
Slide plate described in technique scheme is custom-designed for the spindle drum in the main spindle box in mechanism one and mechanism two, as shown in Figure 6, its structure not only makes the installation of main spindle box and spindle drum be convenient to realize, and is convenient to the adjustment of the perpendicularity of main shaft and work top simultaneously.In addition, slide plate is easy to process, and machined surface is few, is adding man-hour, only need to guarantee the machining accuracy of the minority polished surfaces such as main spindle box/spindle drum installed surface of slide plate and slide plate right side boss medial surface.
The invention has the beneficial effects as follows, can guarantee the installation accuracy of electric main shaft and the accuracy that motion is transmitted, can adjust quickly and easily the perpendicularity of main shaft and work top, improve machining accuracy and working (machining) efficiency, can fully demonstrate the feature of numerical controlled engraving and milling device, for producer brings larger economic benefit.
