[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses an aero-engine measurement platform.

[0025] This utility model provides, for example Figure 1-3 The aero-engine measurement platform shown includes a base 1, a U-shaped plate 2 fixedly connected to the upper surface of the base 1, circular holes on both sides of the U-shaped plate 2, a circular block 3 rotatably connected inside the circular holes, a placement groove fixedly connected to one side of the circular block 3, an aero-engine body 4 disposed inside the placement groove, a cavity opened inside the circular block 3, a fixing mechanism disposed inside the cavity, the aero-engine body 4 being fixedly connected to the inside of the placement groove through the fixing mechanism, a drive mechanism disposed on the upper surface of the base 1, and the circular block 3 being rotated by the drive mechanism.

[0026] The aircraft engine body 4 is fixed inside the placement slot. The aircraft engine body 4 can then be rotated by rotating the circular block 3 to facilitate the measurement work of the staff.

[0027] To fix the aircraft engine body 4, such as Figure 1-3As shown, the fixing mechanism includes a cylinder 5, a first trapezoidal block 6, two second trapezoidal blocks 7, a T-shaped block 8, two connecting blocks 9, and two arc-shaped clamping plates 10. The cylinder 5 is fixedly connected to one side of the circular block 3. The output end of the cylinder 5 passes through one side of the circular block 3 and extends into the cavity. The two second trapezoidal blocks 7 are slidably disposed inside the cavity. The inclined surfaces of the two second trapezoidal blocks 7 are provided with T-shaped grooves. The two T-shaped blocks 8 are slidably disposed inside the corresponding T-shaped grooves. The first trapezoidal block 6 is fixedly connected between the two T-shaped blocks 8. The two connecting blocks 9 are fixedly connected to one side of the corresponding second trapezoidal block 7. One end of each connecting block 9 passes through one side of the cavity and is fixedly connected to the corresponding arc-shaped clamping plate 10. Two strip holes are opened between the cavity and the placement groove. The two strip holes are matched with the corresponding connecting blocks 9.

[0028] After cylinder 5 starts, the output end pushes the first trapezoidal block 6 into the cavity, and the two T-shaped blocks 8 slide along the T-groove of the second trapezoidal block 7, causing the second trapezoidal block to unfold to both sides. The connecting block 9 moves with the second trapezoidal block, so that the arc-shaped clamping plate 10 is tightly attached to the outer wall of the aircraft engine body 4, thereby fixing the aircraft engine body 4.

[0029] In order to make the aircraft engine body 4 rotate, such as Figure 1-2 As shown, the drive mechanism includes a motor 11, a gear 12 and an external gear ring 13. The external gear ring 13 is fixedly sleeved on the outer surface of the circular block 3. The motor 11 is fixed to one side of the U-shaped plate 2. The output end of the motor 11 passes through one side of the U-shaped plate 2. The gear 12 is fixedly sleeved on the output end of the motor 11 and meshes with the external gear ring 13.

[0030] The gear 12 at the output end of the motor 11 meshes with the external gear ring 13, driving the circular block 3 to rotate within the circular hole of the U-shaped plate 2. Subsequently, the circular block can drive the engine to achieve rotation without dead angles.

[0031] To support the other end of the aircraft engine body 4, such as Figure 1-2 As shown, a support block 14 is fixedly connected to the upper surface of the base 1. An arc-shaped groove is opened on the upper surface of the support block 14. The arc-shaped groove matches the aircraft engine body 4. Multiple spherical grooves are set inside the arc-shaped groove, and each spherical groove contains a ball bearing 15.

[0032] The ball bearings 15 are evenly distributed in the arc-shaped groove of the support block 14. When the engine body is placed, the ball bearings form point contact with the outer wall of the engine, converting sliding friction into rolling friction, thus avoiding rotational jamming caused by excessive friction.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
