[0025] Example 1

[0026] This embodiment provides a rotational testing apparatus; please refer to [link / reference]. Figure 1 and Figure 2 The system includes a first clamping assembly 1 and a second clamping assembly 3. The first clamping assembly 1 includes a first mounting frame 11, a rotating mechanism 12, and a first clamp 13. The first clamp 13 is used to clamp the workpiece 2. The rotating mechanism 12 is disposed on the first mounting frame 11 and connected to the first clamp 13. The rotating mechanism 12 can drive the workpiece 2 to rotate through the first clamp 13. The second clamping assembly 3 includes a second mounting frame 31 and a second clamp 32. The second clamp 32 is disposed on the second mounting frame 31 and can be adjusted in the horizontal and / or vertical direction to clamp the workpiece 2. The second mounting frame 31 can drive the second clamp 32 to move in the direction close to or away from the first mounting frame 11.

[0027] Workpiece 2, such as a waveguide rotary joint, is clamped by the first clamp 13 of the first clamping assembly 1. The rotating mechanism 12 on the first mounting frame 11 drives the workpiece 2 to rotate through the first clamp 13. In order for the workpiece 2 to rotate for rotation testing, the second clamp 32 of the second clamping assembly 3 needs to clamp the workpiece 2 synchronously. In addition, by setting the second clamp 32 to be able to move relative to the second mounting frame 31 in the horizontal and / or vertical directions, the relative position with the workpiece 2 can be adjusted, which facilitates clamping and improves flexibility. Moreover, the second mounting frame 31 can drive the second clamp 32 to move in the direction close to or away from the first mounting frame 11, so as to adjust the center distance between the first clamp 13 and the second clamp 32, thereby making it suitable for clamping workpieces 2 of different sizes and shapes, improving the testing flexibility and testing efficiency for workpieces of different sizes and shapes.

[0028] The rotating mechanism 12 includes a rotating motor 121 and a reducer 122. The rotating motor 121 and the reducer 122 are both fixedly connected to the first mounting bracket 11 by bolts. The rotating motor 121 is connected to the first clamp 13 through the reducer 122 and drives the first clamp 13 to rotate through the reducer.

[0029] In the optional embodiment, more preferably, the first clamp 13 includes two first clamping plates 131, which are used to clamp the workpiece 2. The two first clamping plates 131 are arranged opposite to each other and connected to the rotating mechanism 12 through the first adjusting mechanism 14. The first adjusting mechanism 14 can drive the two first clamping plates 131 to move in a direction that moves closer to or further away from each other.

[0030] The workpiece 2 can be stably clamped by setting two first clamping plates 131. The two clamping plates 131 can clamp or release the workpiece 2 through the first adjustment mechanism 14. Moreover, the first adjustment mechanism 14 can adapt to the clamping of workpieces 2 of different sizes by adjusting the distance between the two first clamping plates 131.

[0031] In an optional embodiment, more preferably, the first adjustment mechanism 14 includes a first fixed plate 141, two first limiting plates 142, and two first adjustment members 143.

The two first clamping plates 131 are slidably connected to the first fixed plate 141.

The first clamping plate 131 is slidably connected to the first fixed plate 141 via the first connecting plate. The first clamping plate 131 can slide and engage with the first fixed plate 141 by setting a C-shaped slider at one end of the first connecting plate and a C-shaped groove on the first fixed plate 141. Under the sliding guidance of the first fixed plate 141 on the first connecting plate, rotating the first adjusting bolt drives the first clamping plate 131 to reciprocate linearly through the first connecting plate. The first limiting plate 142 can also play a limiting role. In addition, the first adjusting component 143 can also be configured as other adjusting mechanisms such as an electric telescopic rod, which directly drives the first clamping plate 131 to move through extension and retraction.

[0034] In the optional embodiment, more preferably, the second clamping component 3 further includes a position adjustment mechanism 33, which is disposed on the second mounting bracket 31, and the second clamp 32 is disposed on the position adjustment mechanism 33. The position adjustment mechanism 33 can adjust the position of the second clamp 32 in the horizontal and vertical directions.

[0035] The position adjustment mechanism 33 can be configured as a conventional cross slide mechanism, specifically a precision cross slide, which is fixedly connected to the second mounting bracket 31 by bolt connection.

[0039] The second fixed plate 321 is fixedly connected to the position adjustment mechanism 33 by means of bolts, and the two second limiting plates 323 are fixedly connected to the two sides of the second fixed plate 321 by bolts.

The second clamping plate 322 can slide and cooperate by having a C-shaped groove on one end of the second connecting plate and a C-shaped slide rail on the second fixed plate 321. Under the sliding guidance of the second fixed plate 321 on the second clamping plate 322, rotating the second adjusting bolt drives the second clamping plate 322 to move back and forth linearly via the second connecting plate. The second limiting plate 323 can also serve as a limiting device. In addition, the second adjusting component 324 can also be configured as other adjusting mechanisms, such as an electric telescopic rod, which directly drives the movement of the second clamping plate 322 through extension and retraction.

[0042] The clamping surface of the first clamp 13, i.e. the first clamping plate 131, is set as a plane to facilitate stable clamping of the workpiece 2, such as a waveguide rotary joint. The clamping surface of the second clamp 32, i.e. the second clamping plate 322, is provided with an opening groove 325, such as a V-groove, to facilitate clamping of the circumferential segment of workpieces 2 of different sizes, such as waveguide rotary joints. In addition, the clamping surface can also match the shape of the workpiece 2, which can effectively avoid stress concentration, ensure uniform distribution of clamping force, and improve the accuracy of test results.

The first clamping component 1 and the second clamping component 3 can be installed by means of bolt connection, which facilitates the overall integration of the rotation test device. The control box 4 is set up as a conventional electrical box, which can realize the action control of the rotation mechanism 12, the position adjustment mechanism 33 and the linear drive mechanism 35 through wireless or cable means.

[0048] The display screen 42 allows operators to intuitively control the movements of the rotating mechanism 12, the position adjustment mechanism 33, and the linear drive mechanism 35, improving control accuracy and convenience. Furthermore, the display screen 42 can display rotation test information such as the number of rotations and speed.

[0049] The method of using the rotation test device provided in this embodiment is as follows: Pull the second clamping assembly 3 as a whole away from the first clamping assembly 1 until the waveguide rotation joint can be easily inserted. At the same time, make the first clamp 13 clamp the flat end of the waveguide rotation joint and insert the waveguide rotation joint into the opening slot 325 of the second clamp 32.
