Description
Technical field
The present invention relates to centre frame, relate in particular to a kind of vertical lathe that has centre frame.
Background technology
Vertical lathe is mainly used in short large-scale, the heavy workpiece of big, the length of processing diameter and is difficult for the workpiece of clamping on horizontal lathe, in order to meet customer need, when needs processing long-axle workpieces; Traditional installation way just utilizes workbench that one end of workpiece is fixed, because the draw ratio of these workpiece is big, is long tubular; And the workpiece height is high, is adding man-hour, and the other end of workpiece is prone to whipping; Workpiece is subject to the effect of radial cutting force and produces flexural deformation; Cause its endoporus cylindricity of workpiece that processes low, diameter of bore or radius ratio are not up to standard, have oval phenomenon; The whipping of workpiece one end is prone to cause the vibrations of cutter simultaneously, damages cutter, influences processing progress, reduces production efficiency.
Summary of the invention
The applicant provides a kind of simple in structure to above-mentioned situation, the vertical lathe that has centre frame easy for installation, thus improved the processing column degree and the production efficiency of workpiece endoporus.
The technical scheme that the present invention adopted is following:
A kind of vertical lathe that has centre frame comprises on base, the base and installs workbench that base and workbench are connected with column; Column is provided with guide rail; Affixed first crossbeam on guide rail, first crossbeam is provided with slide, installs knife rest on the slide; Be provided with second crossbeam that is slidingly connected with guide rail in the bottom of first crossbeam, second crossbeam connects centre frame.
It is further characterized in that:
Said centre frame comprises upper frame and lower frame, and upper frame and lower frame flexibly connect; The centring means that the position is mutually 120 ° is set on upper frame and lower frame;
Said centring means comprises the supporting cylinder, and supporting has the hole in the cylinder, the device cover hole in, and cover is connected with the threaded one end of screw rod, and the other end through-going device of screw rod is in annular slab and upper cover plate, in the peripheral returning apparatus of annular slab and upper cover plate round overlapping arranged; End at the supporting cylinder also is provided with a supporting arrangement;
Said supporting arrangement comprises one, and the periphery of axle is provided with bearing, the roller of coaxial device, and roller is connected with cover plate;
Returning apparatus sealing ring in said cover plate, the roller, bearing is a cylinder roller bearing.
Beneficial effect of the present invention is following:
The present invention is through after increasing centre frame; Solve the workpiece that diameter reached in the past, length is long and added man-hour; Because of clamp not strongly the solid endoporus cylindricity that causes low, decrease situation such as cutter, through on the periphery of workpiece top, adopting 3 rolling ways of contact workpiece is fixed, cause workpiece to be subject to the effect of radial cutting force and produce flexural deformation and avoid workpiece whipping in rotary course, to occur; And decrease the cutter situation, effectively raise processing progress and production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes that device has workbench 5 on base 4, the base 4; Base 4 and workbench 5 are connected with column 3; Column 3 is provided with guide rail 6, and affixed first crossbeam, 2, the first crossbeams 2 are provided with the slide (not shown) on guide rail 6; Device knife rest 1 is provided with second crossbeam, 9 second crossbeams 9 that are slidingly connected with guide rail 6 in the bottom of first crossbeam 2 and is connected centre frame 8 on the slide.
As shown in Figure 2, centre frame comprises upper frame 801 and lower frame 802, and upper frame 801 flexibly connects with lower frame 802; Be provided with the centring means that the position is mutually 120 ° in upper frame 801 and lower frame 802.Centring means comprises supporting cylinder 810; Supporting has the hole in the cylinder 810, and device cover 805 hole in overlaps 805 and is connected with the threaded one end of screw rod 809; The other end through-going device of screw rod 809 is in annular slab 807 and upper cover plate 808, in the peripheral returning apparatus circle cover 806 of annular slab 807 and upper cover plate 808; End at supporting cylinder 810 also is provided with a supporting arrangement.
As shown in Figure 3, supporting arrangement comprises axle 811, and the periphery of axle 811 is provided with bearing 803, the roller 812 of coaxial device, and said roller 812 is connected with cover plate 813.Returning apparatus sealing ring 815 in cover plate 813, the roller 812, bearing 803 is a cylinder roller bearing, also is provided with a plate 818 in the bottom of axle 811, has the hole in the plate 818, device and the screw that axle 811 is threaded play fixed supporting role in the hole, prevent that axle 811 from coming off.Because axle 811 upper end is big, the lower end is little, and the axle of this shape is the axial float of limiting roller 812 and bearing 803 effectively.
The course of work of the present invention is following:
When the processing draw ratio big, as shown in Figure 2 during highly big workpiece, unclamp screw 804 earlier because upper frame 801 flexibly connects with lower frame 802, lower frame 802 can be opened (open mode is as shown in Figure 4) to next side along axle 817.Like Fig. 1, shown in Figure 4, after opening, through suspender workpiece 7 is winched to the center of centre frame after, as shown in Figure 2, unclamp screw 816, make between annular slab 807 and the upper cover plate 808 and leave the gap; After screw 819 and nut are fastened on and prevent on the annular slab 807 that screw 816 from excessively unclamping, can cause screw 816 and annular slab 807 to come off.This moment rotary screw 809; Because an end of screw rod 809 is to be threaded with cover 805; Cover 805 is affixed with supporting cylinder 810, and the hole that has on supporting cylinder 810 and upper frame 801 and the lower frame 802 is matched in clearance, can drive supporting cylinder 810 thus and slide before and after in the hole and regulate; Three rollers 812 until supporting arrangement contact with the workpiece outer surface and clamping work pieces 7; Tighten screw 816 this moment, and the gap between annular slab 807 and the upper cover plate 808 is eliminated, and promptly accomplishes the clamping (closed condition of lower frame such as Fig. 5, shown in Figure 6) of workpiece.Because bearing 803 adopts cylinder roller bearing, when lathe is worked, can reduce and the workpiece friction, bears bigger friction radial load.
The present invention is through after increasing centre frame; Solve the workpiece that diameter reached in the past, length is long and added man-hour; Situation such as the solid endoporus cylindricity that causes is low because of clamping not strongly, damage cutter; Through on the periphery of workpiece top, adopting 3 rolling ways of contact that workpiece is fixed, avoid workpiece whipping and appearance damage cutter situation in rotary course, to occur, effectively raise processing progress and production efficiency
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of basic structure of the present invention, the present invention can do any type of modification.
