The specific embodiment

As shown in Figure 1 and Figure 2, a kind of unsteady revolution positioning tool mainly is made up of last finger plate 2, lower plate 3, main shaft 1, the whole radius upper slide 9 that withers, adjustment radius lower skateboard 8, screw rod 10, location loose piece 16 and locating shaft 15; Described go up finger plate 2 and lower plate 3 all be cylindric and all therein the heart open the cast iron of circular hole, wherein go up on the upper end face of finger plate 2 and along the circumferential direction offer several grooves; Described several grooves are to be used for several location loose pieces 16 to be stuck in groove, and location loose piece 16 can be in groove art skating along the circumferential direction; Described location loose piece is made up of upper and lower two blocks of square iron, and is provided with two holes is used for bolt upper and lower two blocks of square iron are coupled together on the surface of two blocks of square iron; In addition, the lower bottom part of following square iron is also established an aperture and is used for locating shaft 15 inconsistent; The central hole of described lower plate 3 also is equipped with linear bearing 4;

Main shaft 1 is provided with a step surface and main shaft 1 is to pass linear bearing 4 and pass through last finger plate 2 centre bores, promptly go up on the step surface that finger plate is provided in a side of main shaft 1, main shaft 1 upper end is concordant with last finger plate 2 upper end faces, and main shaft 1 lower end is connected by end bearing 17 with screw rod 10; Described screw rod 10 excircles are provided with screw thread, and are provided with an excircle projection 101 on the excircle of screw rod 10, and promptly the cross section of screw rod 10 forms cross shape; Excircle projection 101 edges of screw rod 10 are welded with an elevating lever 6; The lower end of described screw rod 10 is to be set in the nut seat 7, described nut seat 7 inner peripheral walls be provided with screw rod 10 excircles on corresponding screw thread; Nut seat 7 is fixed on by screw and adjusts on the radius upper slide 10; Lower plate 3 is fixed up by several fixed supports 5 and adjustment radius upper slide 9; Adjust in the radius lower skateboard 8 the screw mandrel (not shown) is installed, and in adjusting radius upper slide 9, be welded with the screw mandrel cover (not shown) that is complementary with this screw mandrel, screw mandrel is in the screw mandrel cover and can carries out pull and slide, the i.e. pull slip of sliding and driving the whole radius upper slide 9 that withers by the screw mandrel pull, thus the center of circle that places the workpiece on the finger plate 2 changed;

When turning elevating lever 6, screw rod 10 screws out in nut seat 7, and promptly driving upward by main shaft 1, finger plate 2 upwards floats;

Locating shaft 15 is installed in the cover for seat 14 of location, and extend downwards through positioning seat 13, the lower end of locating shaft 15 is equipped with spring 12, and at the other end of spring 12 depression bar 11 is housed, by pressing moulded rod 11,, the elastic reaction of spring 12 moves up and down because will driving locating shaft 15; Described location cover for seat 14 is fixed on the positioning seat 13 by screw, and an end of positioning seat 13 is fixed on the edge of lower plate 3 by screw.

The utility model is installed on the common upright drill, and the workpiece blank is positioned on the finger plate 2, with pulling moving elevating lever 6, driving main shaft 1 when to be screw rod 10 screw out in the nut seat 7 moves up, because the centre bore of last finger plate 2 passes main shaft 1 and puts on the step surface of main shaft 1, go up finger plate 2 risings so main shaft 1 drives when rising, finger plate 2 is separated with upper plate 3; Simultaneously pressing lever 11 makes locating shaft 15 move down, and then makes locating shaft 15 break away from the hole that offsets on the square iron block below the location loose pieces 16, can rotate the position that finger plate 2 comes any hole on the processing work by hand;

When the processing oversize workpiece, also only need to spur the screw mandrel of adjusting on the radius lower skateboard 8, can drive whole work-piece and move forward and backward, thus the home position on the change large-scale workpiece; At this moment spur a location loose piece 16 and be enclosed within on the locating shaft 15, turn elevating lever 6 simultaneously screw rod 10 is moved down, make that going up finger plate 2 is adjacent to lower plate 3, be both two bolts fixing above the location loose piece 16, so just fix the position in a hole.
