The specific embodiment
The elongated taper rod shaft bracket of a kind of turning as shown in Figure 1, 2, a pallet body 1 is arranged, and is carriage rail below the pallet body, and carriage rail 9 matches with lathe bed surface guide rail, its carriage rail faces down, and carriage rail face one side is that level gauge face, opposite side are the V-type rail faces; Two vertical threaded bore are arranged on the carriage rail, screw 5 is housed on the vertical threaded bore, be equipped with on the screw and can be locked at clamp 7 on the machine tool guideway to pallet body, fastening by nut 6, pallet body is fixed on the lathe bed surface guide rail 8; The pallet body top connects a trunnion axis bearing sleeve 2, and bearing holder (housing, cover) is equipped with bearing 3, and brearing bore is the bellmouth that matches with the awl bar tapering of the elongated taper rod shaft of workpiece to be machined.
The priming cup 4 of oiling voluntarily is installed on the bearing holder (housing, cover) on the pallet body, and the oilhole on the bearing holder (housing, cover) communicates with bearing, and the oil groove on the porose and bearing inner conical hole wall on the bearing communicates.
The side of pallet body is factory's font support.
Put on the guide rail of tailstock originally at the rear portion that the elongated taper rod shaft bracket of a kind of turning, pallet body are installed in lathe, and its center is to overlap fully with main shaft.There are level gauge and V-type rail and machine tool guideway to match below the pallet body, can on machine tool guideway, carry out axial slip arbitrarily, determine that in the position back fixes it with screw.The bearing holder (housing, cover) that can roll is installed on carriage, the cylindrical of bearing holder (housing, cover) be with pallet body in the hole be slidingly matched, the area of bearing holder (housing, cover) contact is 30 times of centre frame Area of bearing.Feasible support is more steady, and the endoporus of bearing holder (housing, cover) has tapering, partly matches with the elongated awl bar that will support exactly.The diameter of awl bar was changed when the hole size basis connect cutter in the bearing holder (housing, cover), studded with bearing in the place of bearing holder (housing, cover) and pallet body plane contact, to bear the axial force of cutting, had reduced the friction with carriage.And the pallet body endoporus does not have the lubricating oil line, and what lubricating cup did not stop is lubricated bearing holder (housing, cover), guarantees the smooth rotation of bearing holder (housing, cover), thereby has guaranteed normally carrying out of cutting.
