[0006] Further, the oil flinger pressing cylinder has a sleeve portion that is sleeved on the crankshaft shaft portion, and the sleeve portion has a stepped shaft shape with a gradually increasing diameter from top to bottom and is transitionally connected to the oil flinger pressing ring.

[0007] Further, the number of rollers is two, and they are symmetrically arranged on the mounting arm of the lower part of the oil flinger rotating machine.

[0008] The utility model has the advantages of simple fixture structure, low manufacturing cost, convenient clamping, significantly improved oil flinger press -fitting efficiency and improved installation stability of oil flinger. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 is the structural schematic diagram of the utility model;

[0010] Fig. 2 is a structural schematic view of the positioning plate. DETAILED DESCRIPTION

[0011] The utility model discloses a positioning plate structure.

[0012] A crankshaft oil flinger press fitting clamp as Figs. 1-2 shown, comprising base 9, positioning plate 8, height difference cushion block 7, oil flinger pressing cylinder 5, fixed column 3, oil flinger rotating machine 1. Positioning plate 8 is arranged on the top surface of base 9, and positioning plate 8 is provided with positioning groove 10, and positioning groove 10 is in U type, facilitating the installation of the crankshaft. Positioning plate 8 is provided with a sunken platform, and height difference cushion block 7 is arranged on the sunken platform, and height difference cushion block 7 supports the crankshaft crank part. Oil flinger pressing cylinder 5 is located directly above height difference cushion block 7. Fixed column 3 is floatingly arranged on oil flinger rotating machine 1, and oil flinger rotating machine 1 is connected with lifting driving unit and rotary driving unit, and the lower end of fixed column 3 abuts against the upper end surface of oil flinger pressing cylinder 5. Oil flinger pressing cylinder 5 is provided with oil flinger pressing ring 52 at the lower end, and oil flinger rotating machine 1 is provided with roller 2 corresponding to the outer side of oil flinger pressing ring 52 at a predetermined distance.

[0013] Oil flinger pressing cylinder 5 is provided with sleeve part 51 sleeved on the shaft part of the crankshaft, and sleeve part 51 is in the shape of stepped shaft gradually increasing in diameter from top to bottom and is connected with oil flinger pressing ring 52 in transition.
