Abstract
The invention discloses a multiple-unit roller unloading mechanism for a gantry machine tool. The mechanism comprises a cross beam, wherein the cross beam is provided with a sliding plate which bears load through a supporting surface on the cross beam; an unloading beam is fixed on the cross beam; the upper ends of a plurality of groups of springs are pressed on the sliding plate; the lower end of each spring is pressed on a corresponding supporting seat; each supporting seat is provided with a roller; and each roller is positioned on the unloading beam. Since the cross beam is provided with the unloading beam, and a spring supporting mechanism is arranged between the unloading beam and the sliding plate, the load born on the supporting surface is reduced, the wear of the supporting surface is relieved, the service life of the mechanism can be prolonged, and the problem of deformation of the cross beam is also solved.
Description
Technical field
The present invention relates to a kind of unloading mechanism, particularly a kind of many groups roller unloading mechanism that is used for gantry machine tool.
Background technology
Gantry machine tool has two fixing columns, is horizontally arranged with crossbeam above column, and slide plate is installed on crossbeam, and slide plate is by the supporting surface load-bearing on the crossbeam, and slide plate connects driving mechanism.During work, driving mechanism can drive slide plate horizontal slip on crossbeam.The gantry machine tool supporting surface of this structure is carrying the weight of all parts on slide plate and the slide plate, causes the supporting surface serious wear.
Summary of the invention
The purpose of this invention is to provide the many groups roller unloading mechanism that is used for gantry machine tool that the load-bearing of a kind of crossbeam upper support face alleviates, weares and teares and reduce, overcome the deficiencies in the prior art.
The many groups roller unloading mechanism that is used for gantry machine tool of the present invention comprises crossbeam, is furnished with slide plate on crossbeam, and slide plate is by the supporting surface load-bearing on the crossbeam; Be fixed with the off-load beam on crossbeam, the upper end of organizing spring leans on slide plate more, and the lower end of each spring leans on corresponding bearing, and roller all is installed on each bearing, each roller all be seated in the off-load beam above.
The many groups roller unloading mechanism that is used for gantry machine tool of the present invention is fixed with thread bush on the wherein said slide plate, is furnished with hold-down bolt mutually with thread bush, is provided with pressing plate in the termination of hold-down bolt, and the upper end of described spring leans the bottom surface at pressing plate.
The many groups roller unloading mechanism that is used for gantry machine tool of the present invention, wherein said spring is the butterfly spring.
The many groups roller unloading mechanism that is used for gantry machine tool of the present invention has cushion block between the lower end of wherein said spring and the bearing, fixedlys connected between cushion block and the bearing; Described roller is a bearing, matches above the outer ring of this bearing and the described off-load beam, and bearing is installed on the bearing by axle.
The many groups roller unloading mechanism that is used for gantry machine tool of the present invention because the off-load beam is arranged, has the spring supporting mechanism between off-load beam and slide plate on crossbeam, reduced the load-bearing of supporting surface, alleviate the wearing and tearing of supporting surface simultaneously, can prolong its service life, also overcome the problem on deformation of crossbeam.
Description of drawings
Fig. 1 is the structural representation that the present invention specifically executes mode;
Fig. 2 is an A-A sectional schematic diagram shown in Figure 1;
Fig. 3 is the structural representation of slide plate, crossbeam, off-load beam.
The specific embodiment
As shown in Figure 1, 2, 3: 16 is the crossbeam of Longmen machine tool, and supporting surface 14 is arranged on the crossbeam 16, is furnished with slide plate 5 mutually with crossbeam 16, and slide plate 5 can drive horizontal slip on crossbeam 16 by driving mechanism.
On slide plate 5, be processed with a plurality of holes 17, the step place of the top in each hole 17 is fixed with thread bush 4 by cover plate 2 and set bolt 3, is furnished with hold-down bolt 1 mutually with the internal thread hole of thread bush 4, in the lower end of hold-down bolt 1 pressing plate 6 is arranged, below pressing plate 6, be provided with butterfly spring 7, there is cushion block 8 lower end of spring 7, there is bearing 10 lower end of cushion block 8, be connected by connecting bolt 9 between cushion block 8 and the bearing 10, on bearing 10, roller 11 is installed by axle 13, roller 11 is a bearing, and is connected with end cap 15 at the termination of axle 13 screw.Horizontal direction is fixed with off-load beam 12 on crossbeam 16, for bolting is connected, matches above the outer ring of bearing and the off-load beam 12 between off-load beam 12 and the crossbeam 16, promptly be seated in off-load beam 12 above.After the installation, can adjust the size of the support force of 12 pairs of slide plates 5 of off-load beam by adjusting hold-down bolt 1.Because off-load beam 12 has supporting role, can alleviate the load-bearing of crossbeam supporting surface 14, has also reduced the wearing and tearing of supporting surface 14, and the existence of off-load beam 12 is arranged, and has also overcome the problem of crossbeam 16 stress deformations.
