The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises 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, affixed first crossbeam 2 on guide rail 6, first crossbeam 2 is provided with the slide (not shown), device knife rest 1 is provided with second cross beam 9 second cross beams 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 is flexibly connected 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 arranges a supporting arrangement.
As shown in Figure 3, supporting arrangement comprises an axle 811, outer bearing 803, the roller 812 that is arranged with coaxial device of axle 811, and described roller 812 is connected with cover plate 813.Cover plate 813, roller 812 interior returning apparatus sealing rings 815, bearing 803 is cylinder roller bearing, also is provided with a plate 818 in the bottom of axle 811, has the hole in the plate 818, the screw that device is threaded with axle 811 in the hole play fixed supporting role, and prevents that axle 811 from coming off.Because the upper end of axle 811 is large, the lower end is little, and the axle of this shape can effectively limit the axial float of roller 812 and bearing 803.
The course of work of the present utility model is as follows:
When the processing draw ratio is large, during highly large workpiece, as shown in Figure 2, unclamp first screw 804, because upper frame 801 is flexibly connected with lower frame 802, lower frame 802 can be opened (open mode is as shown in Figure 4) along axle 817 to next side.Such as Fig. 1, shown in Figure 4, after opening, by 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; Screw 819 and fastening nuts can cause screw 816 and annular slab 807 to come off after annular slab 807 prevents that screw 816 from excessively unclamping.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 thus the front and back slip in the hole of supporting cylinder 810 regulates, until three rollers 812 of supporting arrangement contact with outer surface of workpiece and clamping work pieces 7, tighten screw 816 this moment, gap between annular slab 807 and the upper cover plate 808 is eliminated, namely finish the clamping (closed condition of lower frame such as Fig. 5, shown in Figure 6) of workpiece.Because bearing 803 adopts cylinder roller bearing, can reduce and friction of workpiece when lathe is worked, and bears larger friction radial load.
The utility model is by after increasing centre frame, solve the workpiece that diameter reached in the past, length is long and added man-hour, the situations such as the solid endoporus cylindricity that causes is low because clamping not strongly, damage cutter, by adopting 3 rolling ways of contact that workpiece is fixed at workpiece top periphery, avoid workpiece whipping and appearance damage cutter situation in rotary course, to occur, effectively raise processing progress and production efficiency.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that without prejudice to basic structure of the present utility model, the utility model can be done any type of modification.
