Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0027] like Figure 6 As shown, the main reducer housing cover blank 6 is cast and includes a bearing outer ring 63 for installing bearings and oil seals, two ribs 62 arranged opposite to each other on the left and right (to enhance structural strength), and a plurality of (at least three) process press feet 61 arranged at intervals on its edge (to facilitate clamping machine processing).

[0028] like Figure 1-5 As shown, the utility model discloses a machining tool for a main reducer housing cover blank, comprising a base plate 1 that can be positioned and installed on a machine tool, a centering mechanism 2, at least three pressing mechanisms 3 and a plurality of auxiliary support devices 4 that can support the outer edge of the main reducer housing cover blank 6 are positioned and installed in the middle of the base plate 1, and the auxiliary support devices 4 are arranged at intervals between the pressing mechanisms 3 (to ensure the stability of the support and the reliability of the pressing); the centering mechanism 2 comprises a mounting seat positioned and installed on the base plate 1 and a first positioning block 21 and two second positioning blocks 22 with a V-shaped opening installed on the mounting seat, and a circular space for engaging and positioning the outer ring 63 of the bearing is formed between the V-shaped opening of the first positioning block 21 and the two second positioning blocks 22; the pressing mechanism 3 comprises a support 38 positioned and installed on the base plate 1, a swivel cylinder 31 and a support seat 33 that can support the process pressure foot 61 are installed on the support 38, and a pressing block 32 that can press the process pressure foot 61 is installed at the shaft end of the swivel cylinder 31.

[0029] The V-shaped opening of the first positioning block 21 on the centering mechanism 2 and the two second positioning blocks 22 are engaged to position the outer ring of the bearing 63, so as to realize the centering of the main reducer housing cover blank 6; the outer edge of the main reducer housing cover blank 6 is supported by the auxiliary support device 4, the process pressure foot 61 is supported by the support seat 33, and the process pressure foot 61 is pressed by the pressure block 32, so as to realize the reliable and accurate clamping of the main reducer housing cover blank 6, avoid the inaccurate centering of the main reducer housing cover blank and the uneven clamping phenomenon, and ensure the machining accuracy. The use of the angle cylinder 31 can realize the convenience of clamping and avoid interference in the removal and placement of the main reducer housing cover blank 6. The overall structure is simple, easy to use, and practical.
