During the operation of the assembling device 100, the guide member 30 can be driven by the driving member 20 to be sleeved on the oil pump housing 200 through the guide hole 321, so that the position state of the whole oil pump housing 200 can be corrected, and the central axis of the oil pump housing 200 coincides with the central axis of the mounting hole 310 of the crankshaft 300.

Referring to fig. 1 to 3, in some embodiments, the guide member 30 includes a connecting frame 31 and a guide member 32, the connecting frame 31 is fixedly connected to the driving member 20, the guide member 32 is mounted on the connecting frame 31, and the guide member 32 is formed with a guide hole 321, and the guide hole 321 is located on a side of the connecting frame 31 facing away from the driving member 20.

In this way, the guide member 30 is coupled to the guide 32 via the coupling bracket 31, and the oil pump housing 200 can be guided and corrected while being moved by the driving member 20, thereby facilitating smooth press-fitting of the oil pump housing 200 into the crankshaft 300.

Specifically, the connection frame 31 of the guide member 30 may have an upper portion having a vertical shape and a lower portion having a horizontal shape vertically connected to the upper portion. One side of the upper portion of the connecting frame 31 may be fixedly connected to the driving member 20 by welding, bolting, riveting, or other fixing means.

The guide hole 321 of the guide member 32 may be located at a central region of the guide member 32.

Referring to fig. 1, 3 and 4, in some embodiments, the guiding holes 321 include a first hole 3211 and a second hole 3212 communicating with the first hole 3211, the second hole 3212 is located above the first hole 3211, a hole wall 3213 of the first hole 3211 is tapered, and an upper hole diameter D1 of the first hole 3211 is smaller than a lower hole diameter D2 of the first hole 3211.

In this way, in the process of guiding the oil pump case 200 by the guide hole 321, the oil pump case 200 can be corrected in the axial direction of the crankshaft 300 by gradually adjusting the oil pump case 200 through the tapered surface of the first hole 3211, so that the oil pump case 200 enters the second hole 3212.

Specifically, the guide hole 321 may have a stepped cylindrical shape as a whole, the guide hole 321 may have two holes communicating with each other, and the first hole 3211 may have a tapered shape. It is understood that the taper is an inverted funnel shape having a large lower portion and a small upper portion, i.e., the diameter D1 of the upper portion of the second hole 3212 is smaller than the diameter D2 of the lower portion of the second hole 3212. The first hole 3211 may be located at a lower portion of the guide hole 321, and the first hole 3211 may have a trapezoidal sectional shape. The upper portion of the first hole 3211 may be connected to the second hole 3212, the cross-sectional shape of the second hole 3212 may be rectangular, and the overall diameter D3 of the second hole 3212 may be the same.

Thus, the second hole 3212 is provided to further guide the oil pump housing 200 in the axial direction of the crankshaft 300 after passing through the first hole 3211. The oil pump housing 200 may be locked into the second hole 3212 to achieve a more stable position for facilitating subsequent pressing into the crankshaft 300.

Specifically, the second hole 3212 may be located at an upper region of the guide hole 321 of the guide 32, the second hole 3212 may be cylindrical in overall shape, and the second hole 3212 may be rectangular in cross-section. The bore diameter of the second hole 3212 may match the width of the oil pump housing 200. In the process that the oil pump housing 200 enters the guide hole 321, the second hole 3212 can reduce a gap between the oil pump housing 200 and the hole wall 3213 of the guide hole 321, and in the process that the guide piece 32 moves towards the oil pump housing 200, the second hole 3212 can gradually clamp and fix the oil pump housing 200, so that the oil pump housing 200 is kept to accurately face the axis direction of the crankshaft 300.

In some embodiments, after the lower end surface of the guide 32 contacts the upper end surface of the crankshaft 300, the lowering operation of the guide 32 is stopped, and at this time, the oil pump housing 200 is guided and protrudes through the guide hole 321 out of the upper end surface of the guide 32.

Specifically, the depth H1 of the first hole 3211 may be the height of a trapezoid when the cross-section of the first hole 3211 is trapezoidal. Similarly, the depth H2 of the second hole 3212 may be the width of a rectangle when the second hole 3212 is rectangular in cross-section. The depth H1 of the first hole 3211 and the depth H2 of the second hole 3212 may make up the depth of the guide 32 as a whole, with the depth H1 of the first hole 3211 being greater than the depth H2 of the second hole 3212.
