specific Embodiment approach 1

[0045] Specific implementation mode one: as figure 1 and figure 2 As shown, the bearing seat shell described in this embodiment is composed of two identical semi-annular bearing seat shells 1;

[0046] A set of holes are respectively set at the front and rear ends of each semi-annular bearing housing 1, and the mid-section planes of the two semi-annular bearing housings 1 are aligned and fixedly connected by bolts;

[0047]The outer surface of the bearing housing is provided with a ring of protrusions, forming an annular protrusion 11, which is close to the right end of the bearing housing, and the axis of the annular protrusion 11 coincides with the axis of the bearing housing; The diameter of the first outer circle 12 of the bearing housing on the left side of the annular protrusion 11 is greater than the diameter of the second outer circle 13 of the bearing housing on the right side of the annular protrusion 11;

[0048] The diameter of the cylinder mouth at the left and...

specific Embodiment approach 2

[0069] Specific implementation mode two: as Figure 11 and 12 As shown, the eccentric imitation tapered tool bar 14 in the fourth step of this embodiment includes a first connecting rod 14-1, a first tool bar seat 14-2 and a first tool seat 14-3; The radial cross section of a connecting rod 14-1 is a pseudo-tapered shape;

[0070] The top of the first connecting rod 14-1 is fixedly connected with the bottom end of the first tool holder 14-3, and the bottom end of the first connecting rod 14-1 is fixedly connected with an end of the first tool holder 14-2; the first connection The side ends of the rod 14-1, the first cutter holder 14-3 and the first cutter holder 14-2 are flush, and the axial centerline of the first connecting rod 14-1 is aligned with the axis of the first cutter holder 14-2. Compared with the axis of the first tool seat 14-3, it is closer to the said side end flush;

[0071] The first tool seat 14-3 is provided with a first clamping groove 14-3-1, and two b...

specific Embodiment approach 3

[0074] Specific implementation mode three: as Figures 8 to 10 As shown, the eccentrically enlarged long-head cutter bar 15 in step four described in this embodiment includes a second connecting rod 15-1, a second cutter bar seat 15-2 and a second tool bar seat 15-3;

[0075] The top of the second connecting rod 15-1 is fixedly connected with the bottom end of the second tool seat 15-3, and the bottom end of the second connecting rod 15-1 is fixedly connected with an end of the second knife bar seat 15-2; the second connection The side ends of the bar 15-1, the second tool bar seat 15-2 and the second tool bar seat 15-3 are flush, and the axis of the second connecting rod 15-1 is aligned with the axis of the second tool bar seat 15-2 and the second tool bar seat 15-2. The axis of the tool seat 15-3 is relatively close to the side end flush;

[0076] The second tool seat 15-3 is provided with a second clamping groove 15-3-1, and two bolt holes with internal threads are opened ...

Abstract

The invention relates to a machining technology of bearing seat shells, in particular to a machining method of a small-aperture large-cavity bearing seat shell. An original machining method of the small-aperture large-cavity bearing seat shell needs many steps, and the quality of a machined product is unqualified. The machining method of the small-aperture large-cavity bearing seat shell comprisesthe following steps that firstly, a blank is roughly machined into a cylindrical workpiece, the cylinder workpiece is divided into two identical semi-ring-shaped workpieces, the split of each semi-ring-shaped workpiece is fine machined, the two semi-ring-shaped workpieces are combined, and holes are drilled; secondly, the outer circles and the end faces of the semi-ring-shaped workpiece are finegrinded; thirdly, the two semi-ring-shaped workpieces are combined through benchwork; fifthly, multiple inner holes in the bearing seat shell, the left end face and right end face of the bearing seatshell and the outer circle of the bearing seat shell are accurately turned; fifthly, the two semi-ring-shaped bearing seat shells are opened by means of benchwork; sixthly, holes for assembly of the two semi-ring-shaped bearing seat shells are machined; seventhly, oil seal is conducted. The machining method is used for machining the bearing seat shell.

Description

technical field [0001] The invention relates to the processing technology of a bearing seat shell, in particular to a processing method of a bearing seat shell with a small orifice and a large cavity. Background technique [0002] The structural characteristics of bearing housing shell products are small openings and large cavities, strict requirements on shape and size tolerances and dimensional tolerances, and bearing housing shells are assembled from upper and lower halves of bearing housing shells; the original small hole There are many steps in the processing method of the bearing seat shell with a mouth and a large cavity, and the processed products will have wrong teeth after assembly, and the cavity sizes of the upper and lower halves of the bearing seat shell are inconsistent, resulting in shape and position The tolerance and dimensional tolerance are out of tolerance, which seriously affects the quality of the product. Contents of the invention [0003] The tech...
