Embodiment
Below the present invention is described in further details. See Fig. 1 to Fig. 5, a kind of thread jaw chuck auxiliary positioning supporting device, it is characterised in that: it is made up of base plate 1, base plate retaining screw 2,2 strut members that structure is identical 3, strut member retaining screw 4 and 2 clamping screw rods 5; Base plate 1 is a rectangular plate 1a, the upper surface of base plate 1 has a base plate boss 1b that stretch along its length, that cross section is rectangle, base plate boss 1b has the base plate slotted hole 1c that is through, on rectangular plate 1a, base plate boss 1b both sides respectively have the base thread hole 1d of the spacing such as a row; Strut member 3 has, by what bottom had the bearing 3c of rectangular parallelepiped profile and top, the L-shaped component that the support arm 3b of rectangular parallelepiped profile connects to form, bearing 3c has the bearing slotted hole 3d of a through bearing 3c upper and lower surface, have the support arm threaded hole 3a that through in the upper end of support arm 3b, the axis of support arm threaded hole 3a is vertical with the center bisector of bearing slotted hole 3d width; Strut member retaining screw 4 is screwed in the 1d of base thread hole after bearing slotted hole 3d, is fixed on base plate 1 by strut member 3, and 2 strut members 3 are positioned at the both sides of boss 1b, and boss 1b is symmetrical relatively; 2 clamping screw rods 5 are screwed in the support arm threaded hole 3a of 2 strut members 3 respectively, and 2 clamping screw rods 5 are coaxial; At least 2 base plate retaining screws 2 are screwed in the threaded hole on thread jaw chuck 6 after base plate slotted hole 1c, are fixed on by auxiliary positioning supporting device on thread jaw chuck 6; Part to be processed 7 clamping is in the three-jaw of thread jaw chuck 6, and the cantilever structure on part to be processed 7 extends radially, and is clamped screw rod 5 clamping position by 2.
In order to improve the positioning precision of strut member 3 with base plate 1 and be connected rigidity, have in the lower left corner of strut member 3 bearing 3c a through front and rear surfaces, cross section be the breach 3e at right angle, breach 3e is positioned at below bearing slotted hole 3d, make the face, left side of bearing 3c is formed a bearing boss stretched to the left, bearing slotted hole 3d runs through the upper and lower surface of this bearing boss, the lower surface of this bearing boss and the step surface laminating of base plate 1 base plate boss 1b side.
The using method of the present invention is: first screw on machine chuck 6 in the threaded hole carried by base plate 1 with two base plate retaining screws 2, thus make base plate 1 be fixed on the upper surface of machine chuck 6, two base plate retaining screws 2 are first slightly tightened, then 2 two strut members 3 are fixed on base plate 1 boss both sides upper surface with strut member retaining screw 4 respectively, two strut member retaining screws 4 are first slightly tightened, again part 7 is installed in the three-jaw of chuck 6, part 7 is fitted with the three-jaw upper surface of chuck 6, in the middle of two the clamping the screw rods 5 simultaneously part of required for part 7 circumference location being positioned on two strut members 3, then with the three-jaw clamping part 7 on chuck 6, then the relative position of localization part needed for accurate adjustment base plate 1 and strut member 3 and part 7, object is the corresponding position making clamping screw rod 5 clamp the required location of part 7, tighten two base plate retaining screws 2 and two strut member retaining screws 4 afterwards completely, finally tighten two clamping screw rods 5 by suitable moment spanner symmetry, the supplemental support effect thus held concurrently in the location of part 7 by realization.
