Accordingly, the outer casing 7 has two clamping positions, which are oriented in opposite directions: one where the first side surface 7a and the third side surface 7c serve as two contact surfaces, and the first holes 7a1 serve as positioning holes; and the other where the first side surface 7a and the second side surface 7b serve as two contact surfaces, and the second holes 7c1 serve as positioning holes.

[0035] Please see Figure 3 A mounting part 1 is rotatably connected to a rotating disk 2 about a horizontal axis. A drive part 3 is used to drive the rotating disk 2 to rotate. More specifically, the drive part 3 can be a servo motor, and the rotating disk 2 has a rotating shaft, which can be geared to the output shaft of the servo motor.

[0036] Mounting plate 4 is fixedly connected to rotating disk 2. More specifically, the end face of rotating disk 2 may have a strip-shaped protrusion, and mounting plate 4 is fitted to the end face of rotating disk 2 for positioning and fixedly connected to the strip-shaped protrusion by bolts.

[0037] Correspondingly, the rotating disk 2 can also rotate the outer casing 7 that is subsequently clamped on the mounting plate 4. In addition, the rotating disk 2 can have a standard scale, and a pointer is set on the mounting part 1, so that the tilt angle of the rotating disk 2 can be directly obtained.

[0038] Please see Figure 3 Along the axis of the rotating disk 2, the mounting plate 4 is divided into a first tooling area and a second tooling area. The first tooling area and the second tooling area are used for two clamping positions, respectively.

[0039] Please see Figure 4 and Figure 5 The first clamp 5 is disposed in the first tooling area and includes four first support columns 5a, two first positioning columns 5b, and four first clamping parts 5c. That is, the four first support columns 5a and the two first positioning columns 5b are fixedly connected to the mounting plate 4; the first side 7a of the outer shell 7 is placed on the four first support columns 5a and is supported; two of the four first holes 7a1 on the first side 7a are selected for the insertion of the two first positioning columns 5b, preferably, the two selected first holes 7a1 are diagonally opposite; the four first clamping parts 5c press the second side 7b of the outer shell 7, cooperate with the four first support columns 5a, and press and fix the outer shell 7.

[0040] Please see Figure 4In some embodiments, the pressing points of the two first pressing parts 5c on one side and the two first support columns 5a correspond to the same straight line; the pressing points of the two first pressing parts 5c on the other side and the two first support columns 5a also correspond to the same straight line.

[0041] In some embodiments, the first pressing part 5c is a rotary pressing cylinder. More specifically, when placing the housing 7, the first connecting arm 5c1 of the rotary pressing cylinder can be perpendicular to the axis of the rotating disk 2, so as not to interfere with the housing 7 entering the first tooling area; the housing 7 enters the first tooling area, is placed on the four first support columns 5a and engages with the two first positioning columns 5b; the rotary pressing cylinder moves, the first connecting arm 5c1 rotates to be parallel to the axis of the rotating disk 2, and moves down at the same time to press the housing 7.

[0042] Please see Figure 5 In some embodiments, based on the above-described embodiment where "the first pressing part 5c is a rotary pressing cylinder", the first connecting arm 5c1 is also provided with a threaded through hole, and a bolt 5c2 is threadedly connected to the threaded through hole. The bolt 5c2 is the pressing point of the first pressing part 5c. By rotating the bolt 5c2, the position of the pressing point can be adjusted up and down relative to the first connecting arm 5c1 to ensure that the outer shell 7 can be pressed tightly.

[0043] Please see Figure 4 and Figure 5 The second clamp 6 is located in the second tooling area and includes two second support columns 6a with second positioning posts 6a1 at their top ends and four second clamping parts 6b. That is, the two second support columns 6a are fixedly connected to the mounting plate 4; the third side 7c of the outer shell 7 is placed on the two second support columns 6a and is supported, while the two second positioning posts 6a1 are inserted into the second holes 7c1 on the third side 7c; the four second clamping parts 6b press against the first side 7a of the outer shell 7, cooperating with the two second support columns 6a to press and fix the outer shell 7.

[0044] Please see Figure 4 In some embodiments, the pressing points of the two second pressing parts 6b on one side and the second support column 6a correspond to the same straight line; the pressing points of the two second pressing parts 6b on the other side and the second support column 6a also correspond to the same straight line.

[0045] Please see Figure 5 and Figure 6In some embodiments, the second pressing part 6b includes a second cylinder 6b1, a pressing block 6b2, and a connecting strip 6b3. The middle position of the pressing block 6b2 is hinged to one end of the connecting strip 6b3, and the other end of the connecting strip 6b3 is hinged to the cylinder body of the second cylinder 6b1. The pressing block 6b2 has the aforementioned pressing point on one side of the hinge point. The pressing block 6b2 is hinged to the piston rod of the second cylinder 6b1 on the other side of the hinge point. The extension and retraction of the piston rod of the second cylinder 6b1 causes the pressing block 6b2 and the connecting strip 6b3 to swing together. When the outer casing 7 is placed, the piston rod of the second cylinder 6b1 is retracted, and the pressing point of the pressure block 6b2 is tilted upward, so as not to interfere with the outer casing 7 entering the second tooling area; the outer casing 7 enters the second tooling area, is placed on the two second support columns 6a and is engaged with the two second positioning columns 6a1; the piston rod of the second cylinder 6b1 extends, driving the pressure block 6b2 and the connecting bar 6b3 to swing, and the pressing point on the pressure block 6b2 presses down to hold the outer casing 7 in place.
