Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] see figure 1 and figure 2 , The clamp is mainly composed of guide rod 3, support plate 4, screw mandrel 2 and handle 1. The lower end of the guide rod 3 has a thread that matches the mounting hole 9 of the engine crankshaft 6, and the top is designed with a thimble 18. There are three guide rods, which are respectively screwed into the three mounting holes 9 of the engine crankshaft 6, and the thimble 18 at the top reaches the screw hole Bottom plane. The upper end of the guide rod 3 is designed with a guide chamfer and a radial plane, which is convenient for the ISG motor rotor to be introduced and the guide rod to be tightened by an open-ended wrench. The support plate 4 is strip-shaped, with handles 7 at both ends, which is easy to use. Both ends of the support plate 4 have connecting screw holes 16 corresponding to the mounting screw holes 13 for instal...

Abstract

The ISG motor installing fixture for mixed power engine includes three guide rods, one support board, one lead screw and one handle. Each of the guide rods screwed into the installation holes of the engine crankshaft has threads in the lower end and thimble in the top; the strip support board has connecting screw holes in two ends and central screw hole for the lead screw to pass through; and the lead screw through the central screw hole is screwed into the central hole in the rotor of ISG motor and the end hole in the crankshaft of the engine, with the guide rods penetrating the holes beside the central screw hole. The installing fixture can avoid deviation of the installed rotor, facilitate the installation and disassembling, avoid the damage of the rotor and the stator during assembling and raise work efficiency greatly.

Description

technical field [0001] The invention relates to a special installation fixture. Background technique [0002] The ISG motor is a permanent magnet excitation motor. Its stator is fixed on the cylinder block of the hybrid engine, and the rotor is fixed on the end face of the crankshaft. Since the rotor has a strong magnetic field, positioning pins are installed between the crankshaft and the rotor, so there is no special tool It is difficult to install the rotor on the crankshaft, and the same is true for disassembly, and it may cause friction between the rotor and the stator to damage the magnetic steel sheets and windings. Contents of the invention [0003] The purpose of the present invention is to design a special installation fixture for the problem of difficult installation of the ISG motor of the hybrid engine at present, so as to reduce assembly damage and improve assembly efficiency. [0004] Technical scheme of the present invention is as follows: [0005] The IS...
