[0041] Example:

[0042] See also Figure 1 and Figure 2 This embodiment provides a rotatable tooling, including a base plate 1, a first support plate 2, a second support plate 3 and a connecting rod 4.

[0043] The substrate 1 is perpendicular to the third direction. Since the substrate 1 is horizontally arranged, the third direction is perpendicular to the horizontal plane. The first support plate 2 is also horizontally arranged. The first support plate 2 is located above the substrate 1 so that the substrate 1 and the first support plate 2 are arranged relative to each other in the third direction. The first support plate 2 is rotatably arranged on the substrate 1, and the rotation axis of the first support plate 2 on the substrate 1 is parallel to the third direction. The second support plate 3 is also horizontally arranged and located above the first support plate 2, that is, the second support plate 3 is located on the side of the first support plate 2 away from the substrate 1, and the first support plate 2 and the second support plate 3 are arranged relative to each other and spaced apart in the third direction. The connecting rod 4 extends along the third direction, and the two ends of the connecting rod 4 are respectively fixed to the upper surface of the first support plate 2 and the lower surface of the second support plate 3, and the first support plate 2 and the second support plate 3 have a sufficient distance through the connecting rod 4.

[0044] See also Figure 5 , Figure 6 and Figure 8 First, the sound absorbing box 100 is placed on the second support plate 3, so that the sound absorbing box 100 can be supported on the side of the second support plate 3 away from the first support plate 2. Figure 11-13 After the sound absorbing box 100 is supported, the fan rack 200 is placed on the sound absorbing box 100, and the fan rack 200 is located on the side of the first support plate 2 away from the base plate 1. At this time, the fan rack 200 can be directly supported on the first support plate 2, or can be supported by the sound absorbing box 100. It is not difficult to understand that since the first support plate 2 and the second support plate 3 are fixedly connected, when the first support plate 2 rotates on the base plate 1, the relative position relationship between the fan rack 200 and the sound absorbing box 100 will not change.

[0045] See Fig.11 , a plurality of screw holes 202 are arranged on the top of the fan rack 200. Under the support and lifting action of the connecting rod 4, the sound absorbing box 100 can be aligned with the screw holes 202 on the inner side of the fan rack 200. When the staff is driving screws into different screw holes 202, they do not need to move around. They only need to rotate the first support plate 2 to control the rotation of the fan rack 200 so that different screw holes 202 are rotated to the staff, which greatly reduces the physical exertion of the staff during the screwing process. After all the screw holes 202 are screwed, the sound absorbing box 100 can be fixed on the fan rack 200.

[0046] Preferably, a plurality of operating notches 24 are provided on the edge of the first supporting plate 2 , and a worker can control the rotation of the first supporting plate 2 while avoiding the wind rack 200 by inserting fingers into the operating notches 24 .

[0047] In order to prevent the screw hole 202 and the sound absorbing box 100 from being misaligned during the rotation of the first support plate 2, the sound absorbing box 100 and the fan frame 200 need to be positioned. The first direction, the second direction and the third direction are perpendicular to each other, and accordingly, the first direction and the second direction are parallel to the horizontal plane.

[0048] See also Figure 1 and Figure 5 A first positioning member 31 and a second positioning member 32 are provided on the second support plate 3, and the first positioning member 31 and the second positioning member 32 are spaced apart in the second direction, so that the sound absorbing box 100 can be clamped between the first positioning member 31 and the second positioning member 32 along the second direction, and then obtain positioning in the second direction on the second support plate 3.

[0049] A third positioning member 33 and a fourth positioning member 34 are also provided on the second supporting plate 3. The third positioning member 33 and the fourth positioning member 34 are spaced apart in the first direction. The third positioning member 33 and the fourth positioning member 34 cooperate to clamp the sound absorbing box 100 in the first direction so that the sound absorbing box 100 is positioned in the first direction on the second supporting plate 3.

[0050] See also Figure 6-Figure 10 The first positioning member 31 and the second positioning member 32 are both positioning blocks with an L-shaped cross section, and are both installed on the side of the second support plate 3 that is away from the first support plate 2, that is, the upper surface of the second support plate 3. Therefore, the sound absorbing box 100 is not directly supported on the upper surface of the second support plate 3, but is supported by the first positioning member 31 and the second positioning member 32.

[0051] See also Figure 1 , Figure 2 , Figure 5 , Figure 11-13 A fifth positioning member 21 and a sixth positioning member 22 are provided on the first support plate 2. The fifth positioning member 21 and the sixth positioning member 22 are spaced apart in the first direction. The wind rack 200 is clamped between the fifth positioning member 21 and the sixth positioning member 22, so that the wind rack 200 is positioned in the first direction on the first support plate 2.

[0052] In this embodiment, a seventh positioning member 23 is further provided on the first supporting plate 2 , and the wind rack 200 abuts against the seventh positioning member 23 along the second direction, thereby the wind rack 200 is unidirectionally positioned in the second direction.

[0053] See also Figure 1 and Figure 5In this embodiment, in the second direction, the first positioning member 31 is located between the second positioning member 32 and the seventh positioning member 23, and the second positioning member 32 is located at the edge of the second support plate 3, so that the second positioning member 32 can be located on the inner side of the wind rack 200, so that the second positioning member 32 can abut against the rack rear plate 201 of the wind rack 200 along the second direction. Therefore, in this embodiment, the wind rack 200 is unidirectionally positioned in the second direction.

[0054] In some other embodiments, an eighth positioning member may be further provided on the first support plate 2, and the eighth positioning member and the seventh positioning member 23 clamp the wind rack 200 in the second direction, thereby enabling the wind rack 200 to be bidirectionally positioned in the second direction.

[0055] See also Figure 3 and Figure 4 The rotatable tooling also includes a rotating assembly, and the first support plate 2 is installed on the base plate 1 through the rotating assembly.

[0056] The rotating assembly includes a first bearing ring 41, a second bearing ring 42 and a ball 43. The first bearing ring 41 is fixed to the side of the first support plate 2 facing the substrate 1, the second bearing ring 42 is fixed to the side of the substrate 1 facing the first support plate 2, and the ball 43 is clamped between the first bearing ring 41 and the second bearing ring 42, thereby allowing the first support plate 2 to rotate on the substrate 1 with less resistance.

[0057] There are at least two balls 43, and generally there are more. The rotating assembly further includes a positioning ring 44, which is provided with at least two positioning holes arranged in sequence along the circumferential direction, and the number of the positioning holes matches the number of the balls 43, so that the balls 43 are rolled and arranged at the corresponding positioning holes, thereby ensuring that the center distance between two adjacent balls 43 remains unchanged. The positioning ring 44 can be supported on the second bearing ring 42.

[0058] Preferably, the rotating assembly further includes a partition 45 and a rotating shaft 46, wherein the partition 45 is located at the center of the first bearing ring 41 and the second bearing ring 42, the partition 45 is fixed to the substrate 1, and the partition 45 is located between the substrate 1 and the first support plate 2. The substrate 1 and the first support plate 2 are spaced apart by the partition 45, thereby reducing the contact area between the substrate 1 and the first support plate 2. One end of the rotating shaft 46 is fixed to the partition 45, and the other end of the rotating shaft 46 is passed through the first support plate 2.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
