Detailed description of the invention
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in the figure, the present embodiment comprises main body locating shaft 1, connecting leg 3, support set 4, and connecting leg 2 one end connect main body locating shaft 1, and the other end connects support set 4, and main body locating shaft 1 is fixed on turning machine; The body 41 that support set 4 comprises connecting axle 42 and is integrated with connecting axle 42, the pyramidal structure of body 4 for outwards opening, inside is hollow, body 4 is provided with multiple openings 43.
Preferably, body 4 is made for elastomeric material; Opening 43 on body 4 is uniformly distributed along body 4 taper seats.
Preferably, the opening 43 on body 4 is extended to the intersection of body 4 and connecting axle 42 by body 4 end faces.
Preferably, body 4 maximum gauges are less than machine tool chief axis 3 internal diameters.
Preferably, main body locating shaft 1 is multidiameter, multidiameter comprises and is positioned at the first shaft part 11 that end is connected with turning machine, be positioned at the 3rd shaft part 14 that the other end is connected with connecting leg 2, and between the first shaft part 11 and the 3rd shaft part 14, coordinate with machine tool chief axis 3 install the second shaft part 12, the second shaft part 12 is diminished shaft, and the miner diameter end of diminished shaft is positioned near the 3rd shaft part 14 sides.
Preferably, the second shaft part 12 is provided with the circular groove 13 of locating with machine tool chief axis 3.
The operation principle of this positioner is below described:
As shown in Figure 1, this positioner is installed in the machine tool chief axis 3 of turning machine, the first shaft part 11 of main body locating shaft 1 is connected with lathe, the second shaft part 12 coordinates installation with machine tool chief axis 3, circular groove 13 on it coordinates with the jackscrew on machine tool chief axis 3, makes main body locating shaft 1 fixing with machine tool chief axis 3.
Long shaft part to be processed 5 is inserted in machine tool chief axis 3 from the positioning chuck of turning machine, and when long shaft part 5 ends arrive the body 41 of support sets 4 when interior, body 41 is inwardly pushed in long shaft part 5 ends.Because body 41 is provided with the opening 43 that is extended to body 41 and connecting axle 42 intersections by body 41 end faces, body 41 adopts elastomeric material to make simultaneously, therefore, in the time that body 41 is squeezed, body 41 can open in radial direction, until the end face of body 41 contacts with machine tool chief axis 3 internal faces.Now, because one end and the connecting leg 2 of support set 4 are fixing, the other end is close to machine tool chief axis 3 inwalls, therefore when after long shaft part 5 end extruding bodies 41, can make long shaft part 5 ends follow machine tool chief axis 3 rotates together, ensure the stable of long shaft part 5 ends, the phenomenon that the part of avoiding in rotation process long shaft part 5 to be positioned at machine tool chief axis 3 bends, improves machining accuracy and the working (machining) efficiency of long shaft part 5.
