[0018] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0019] A cage-type fixing device for machining the inner hole of an aluminum motor housing, in combination with Figures 1 to 2 as shown, includes a bottom plate 1, columns 2 and a top plate 3. Among them, the top plate 3 is located above the bottom plate 1; the columns 2 are arranged between the bottom plate 1 and the top plate 3, so as to form a space for accommodating the aluminum motor housing between the bottom plate 1 and the top plate 3.

[0020] The bottom plate 1 is provided with a positioning hole 11 that penetrates through. The positioning hole 11 is in a two-layer stepped shape that is wider at the top and narrower at the bottom, and is adapted to the bottom of the aluminum motor housing. The positioning hole 11 is used to accommodate the bottom of the aluminum motor housing, so as to facilitate machining the inner hole of the aluminum motor housing.

[0021] A positioning groove 31 is formed at the bottom of the top plate 3. The positioning groove 31 has a three-layer stepped shape that is narrow at the top and wide at the bottom, and is adapted to the top of the aluminum motor housing. The positioning groove 31 is used to accommodate the top of the aluminum motor housing. A through hole 32 is formed through the top of the top plate 3, and the through hole 32 communicates with the positioning groove 31. A top seat 4 is provided on the outer surface of the top of the top plate 3. A threaded through hole is longitudinally formed in the top seat 4. A compression bolt 5 is threadedly connected to the top seat 4 through the threaded through hole formed therein. By rotating the compression bolt 5 downward, the compression bolt 5 can pass through the through hole 32, thereby pressing the aluminum motor housing downward, making the bottom of the aluminum motor housing abut against the positioning hole 11, realizing the fixation of the aluminum motor housing. This not only has a simple operation but also a good fixation effect, and can improve the working efficiency of the inner hole machining of the aluminum motor housing.

[0022] Specifically, the outer contours of the bottom plate 1, the top plate 3 and the top seat 4 are all cylindrical and coaxially arranged; the positioning hole 11, the positioning groove 31, the through hole 32 and the threaded through hole of the top seat 4 are all coaxially arranged. The upright columns 2 are four that enclose a rectangle, and two adjacent ones and the other two adjacent ones are symmetrically arranged between the bottom plate 1 and the top plate 3. The aluminum motor housing can be placed through two adjacent upright columns 2 that are farther apart.

[0023] Mounting screw holes 33 are symmetrically formed in the top plate 3. The mounting screw holes 33 are formed through the top plate 3 and are located outside the positioning groove 31. The mounting screw holes 33 are used for threaded connection with mounting bolts to realize the fixed installation of the device.

[0024] When the utility model is in use, the aluminum motor housing is placed between the bottom plate 1 and the top plate 3 through two adjacent upright columns 2 that are farther apart, so that the bottom of the aluminum motor housing is aligned with the positioning hole 11 and the top of the aluminum motor housing is aligned with the positioning groove 31. The compression bolt 5 is rotated downward to press the aluminum motor housing from the top of the aluminum motor housing and make the bottom of the aluminum motor housing abut against the positioning hole 11, thereby realizing the fixation of the aluminum motor housing for inner hole machining of the aluminum motor housing.
