Abstract
The invention discloses a self-adaptive portal frame of a portal mobile machine tool, comprising a left upright post, a right upright post, a left sliding base and a right sliding base, wherein the left sliding base and the right sliding base are respectively positioned on longitudinal guide rails at two sides of a machine body, and the right upright post is rigidly and fixedly connected with the sliding bases; a support plate is arranged between the left upright post and the sliding bases, the support plate and the upright post arranged above the support plate are rigidly and fixedly connected and is in transverse sliding fit with the sliding base arranged below the support plate; and an inner circulating balance pressure cylinder is arranged at the outer side of the left sliding base, and the outer end of the support plate is connected with a piston rod of the cylinder. When the self-adaptive portal frame works and the whole stress of the portal frame reaches a certain value, the cylinder is automatically unloaded so as to ensure that the portal crane works normally without influencing the machining precision of the machine tool. The self-adaptive portal frame disclosed by the invention is simple and practical, is low in cost and convenient for debugging and installing and is beneficial to reducing the manufacturing difficulty and the installing and debugging difficulty of the machine tool.
Description
Technical field
The present invention relates to a kind of gantry frame, what be specifically related to is gantry frame on a kind of movable gantry lathe, particularly a kind of large-sized gantry framework with adaptive ability.
Background technology
That the movable gantry lathe mostly is is large-scale, heavy type and superduty process equipment, and the gantry frame weight on the lathe is big and stroke is long.In the prior art, the gantry frame of this class lathe mainly is rigidly connected by left and right pillar, back timber and slide and forms, the slide of left and right pillar below is slidingly matched with the fixed guide on lathe bed both sides respectively, framework integral body is bearing on the lathe bed, gantry frame moves forward and backward along bed ways, implements the processing to workpiece.The gantry frame of this structure, require the integral rigidity and the locating accuracy thereof of the depth of parallelism, gantry frame of lathe bed both sides guide rail all very high, the portable lathe of large-sized gantry of particularly high-speed, high accuracy, high strength and overlength stroke, its accuracy of manufacture and installation accuracy require higher.Its reason is, in the installation of lathe and in service, lathe self variations in temperature can cause the physical deformation that gantry frame and bed ways expand with heat and contract with cold in the variation of environment temperature and the processing work process, this distortion must influence machine finish, when deflection is excessive, the damage of rigid connector can be caused, also lathe can be damaged when serious, as not strict design, manufacturing, installation and debugging, above-mentioned consequence then is difficult to avoid.And this situation ubiquity on existing large-scale, heavy movable gantry lathe.
Summary of the invention
The object of the present invention is to provide a kind of gantry frame that is adapted to high-speed, high accuracy, high strength and the portable lathe of overlength stroke large-sized gantry, its can conform variation of variation of temperature and stressed size, adjust the position voluntarily, guarantee the machining accuracy of lathe, thereby reduce the manufacture difficulty and the Installation and Debugging difficulty of lathe.
The technical scheme that realizes above-mentioned purpose is: a kind of self adaptation gantry frame of movable gantry lathe, comprise left and right pillar and left and right sides slide, about two slides lay respectively on the longitudinal rail on lathe bed both sides, it is characterized in that: the column on the right rigidly fixes with slide and is connected; A supporting plate is installed between the column on the left side and the slide, and this supporting plate rigidly fixes and is connected with the column of its top, forms laterally with the slide of its below to be slidingly matched; The outside of left side slide is extended with a holder, and an interior cyclic balance oil pressure cylinder is installed on this holder, and the outer end of supporting plate is connected with the piston rod of oil cylinder.
There are two horizontal parallel guide rails described left slide upper surface, matches with cross slide way on the left slide in the lower surface of described supporting plate.
During work, gantry frame integral body vertically moves along bed ways.If because factor such as stressed and variations in temperature makes gantry frame laterally produce internal stress in the manufacturing of two bed ways and installation accuracy error and the workpiece processing, so, when this stress reaches certain value, overflow valve in the interior cyclic balance oil pressure cylinder will be opened automatically, carries out off-load; Meanwhile, the column on the left side will outwards be offset certain distance under the guiding of supporting plate, adjust the position automatically.The structural rigidity of gantry frame does not weaken during off-load, has so both guaranteed the normal operation at gantry, does not influence the machining accuracy of lathe again.
The present invention is simple in structure, practical, and is with low cost, debugs easy for installationly, reduced the manufacture difficulty and the Installation and Debugging difficulty of lathe, for the precision that improves large-scale and heavy movable gantry lathe provides a kind of guarantee.
Description of drawings
Fig. 1 is the organigram of one embodiment of the invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is that the B of Fig. 1 is to view.
Among the figure: 1. right slide, 2. right column, 3. back timber, 4. left column, 5. supporting plate, 6. left slide, 7. holder, 8. in cyclic balance oil pressure cylinder, 9. guide rail.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, about the main body of gantry frame of the present invention comprises two columns 2,4 and about two slides 1,6 and rigidly fixing be connected about the back timber 3 of two column upper ends, about two slides 1,6 lay respectively on the longitudinal rail on lathe bed both sides.Right column 2 rigidly fixes with right slide 1 and is connected; A supporting plate 5 is installed between left column 4 and the left slide 6, supporting plate 5 is rigidly connected with the left column 4 of its top, there are two horizontal parallel guide rails 9 slide 6 upper surfaces, a left side, match with guide rail 9 on the left slide 6 in the lower surface of supporting plate 5, the bearing of trend of guide rail 9 is vertical with the longitudinal rail on lathe bed both sides; The outside of left side slide 6 is extended with a holder 7, and an interior cyclic balance oil pressure cylinder 8 is installed on the holder 7, and the outer end of supporting plate 5 is connected with the piston rod of oil cylinder 8.
Above-mentioned " left side " and " right side " only are the relative positions at the gantry frame both sides, are not limitation of the invention.Above-mentioned " left side " the unified change can be " right side ", " right side " unified change is " left side ", not change structure of the present invention.
Before the work, be full of the pressure oil that adheres to specification for interior cyclic balance oil pressure cylinder 8.
In the work, gantry frame integral body is along the guide rail lengthwise movement of lathe bed.Because between supporting plate 5 below the left column 4 and the left slide 6 is to be slidingly matched, the outer end of supporting plate 5 is connected with the piston rod of oil cylinder 8, therefore, when the horizontal internal stress variation of gantry frame reached the rated value of designing requirement, the overflow valve in the interior cyclic balance oil pressure cylinder was just opened off-load automatically.At this moment, left column 4 will outwards be offset certain distance under the guiding of supporting plate 5, and cooperating still as before of left slide 6 and bed ways so just guaranteed the normal operation of gantry frame, and can not influence the machining accuracy of lathe.
