The second end of the linkage seat 323 is away from the positioning fixture 31. The holding cylinder 325 is installed on the machine base 1, and the piston rod of the holding cylinder 325 is hinged to the second end of the linkage seat 323. The holding cylinder 325 is electrically connected to the control host 2. The holding seat 324 is detachably connected to the first end of the linkage seat 323. The holding seat 324 is used to press the hollow rotating platform B. The drive mechanism 4 includes a drive motor 41, a tensioner 42, and a lifting device 43. The lifting device 43 and the drive motor 41 are electrically connected to the control host 2. The lifting device 43 is installed on the machine base 1. The lifting device 43 and the drive motor 41 are electrically connected to the control host 2. A tensioner 42 is connected to and used to drive the drive motor 41 for lifting and lowering. The drive motor 41 is located below the positioning fixture 31. The tensioner 42 is detachably connected to the output shaft of the drive motor 41.

The displacement detection mechanism 6 is installed on the machine base 1 and electrically connected to the control host 2. The displacement detection mechanism 6 is used to detect the displacement of the hollow rotating platform B.

[0031] The method for performing no-load testing of the hollow rotary platform B according to this utility model is as follows: First, the testing personnel place the hollow rotary platform B on the positioning fixture 31, so that the positioning fixture 31 is positioned and matched with the central rotary platform; then, the control host 2 controls the two pressing devices 32 to drive the pressing cylinders 325 to drive their respective pressing seats 324 to move, so that the pressing seats 324 of the two pressing devices 32 press the hollow rotary platform B, thus stably installing the hollow rotary platform B onto the machine base 1; next, the control host 2 controls the lifting device 43 to drive the tensioner 42 and the drive motor 41 to rise, so that the tensioner 42 is inserted into the input shaft of the hollow rotary platform B, and the tensioner 42 expands to form a tight fit with the input shaft; then, the control host 2 controls the drive motor 41 to... The hollow rotating platform B is driven to run unloaded. Simultaneously, the control host 2 detects the vibration and displacement of the hollow rotating platform B through the vibration detection mechanism 5 and the displacement detection mechanism 6. After the vibration and displacement detection of the hollow rotating platform B is completed, the control host 2 controls the drive motor 41 to stop running, and the control host 2 controls the lifting device 43 to drive the tensioner 42 and the drive motor 41 to descend, causing the tensioner 42 to disengage from the input shaft of the hollow rotating platform B. Next, the control host 2 controls the two holding devices 32 to control the holding cylinders 325 to drive their respective holding seats 324 to actuate, so that the holding seats 324 of the two holding devices 32 do not press against the hollow rotating platform B. Afterwards, the inspector removes the hollow rotating platform B after the inspection is completed. As can be seen from the foregoing, the operation of the hollow rotating platform B for unloaded testing using this invention is simple.

[0032] Furthermore, the positioning fixture 31 is detachably mounted on the mounting surface 11 of the machine tool 1, the holding seat 324 of the holding device 32 is detachably connected to the linkage seat 323, and the tensioner 42 is detachably connected to the output shaft of the drive motor 41. In this way, the positioning fixture 31, the holding seat 324 and the tensioner 42 can be replaced according to different models of hollow rotary platforms B, thereby making the hollow rotary platform no-load testing equipment A of this utility model highly versatile and adaptable to different models of hollow rotary platforms B. Manufacturers only need to configure the corresponding positioning fixture 31, holding seat 324 and tensioner 42 according to the hollow rotary platform B they produce, which greatly reduces the equipment cost for manufacturers.

[0033] In an embodiment of this utility model, the tensioner 42 of the drive mechanism 4 may include a tensioning seat 421, a tensioning sleeve 422, and a return spring 423; the outer periphery of the upper part of the tensioning seat 421 forms a tensioning conical surface 4211 that gradually expands from top to bottom; the tensioning sleeve 422 is fitted onto the tensioning conical surface 4211, and the tensioning sleeve 422 is provided with a plurality of tensioning spring pieces 4221 that are separated along the circumference of the tensioning sleeve 422, and the tensioning spring pieces 4221 abut against the tensioning conical surface 4211; the return spring 423 is disposed between the tensioning seat 421 and the tensioning sleeve 422, and the upper and lower ends of the return spring 423 abut against the tensioning sleeve 422 and the tensioning seat 421 respectively; and the output shaft of the drive motor 41 is detachably connected to the tensioning seat 421, and the output shaft of the drive motor 41 can be connected to the tensioning seat 421 through a coupling 44. As the lifting device 43 drives the tensioner 42 to rise, after the tensioning sleeve 422 is inserted into the input shaft of the hollow rotating platform B, the continued rise of the tensioning seat 421 will cause the tensioning seat 421 and the tensioning sleeve 422 to move closer to each other, causing the tensioning springs 4221 of the tensioning sleeve 422 to be opened by the tensioning cone surface 4211 (at this time, they are in an expanded state), so that the tensioning springs 4221 of the tensioning sleeve 422 form a tight fit with the inner wall of the input shaft; and when the lifting device 43 drives the tensioner 42 to rise, the tensioning sleeve 422 will be opened by the tensioning cone surface 4211 (at this time, it is in an expanded state), so that the tensioning springs 4221 of the tensioning sleeve 422 form a tight fit with the inner wall of the input shaft; and when the lifting device 43 drives the tensioner 42 to rise, the tensioning sleeve 422 will be opened by the tensioning cone surface 4211. During the descent of device 42, the return spring 423 will drive the tensioning seat 421 and tensioning sleeve 422 to move away from each other, so that the tensioning springs 4221 of tensioning sleeve 422 are not opened by tensioning cone surface 4211, so that the tensioning springs 4221 of tensioning sleeve 422 retract and reset (at this time they are in a retracted state), thereby making the tensioning springs 4221 of tensioning sleeve 422 no longer form a tight fit with the inner wall of input shaft, so that tensioning sleeve 422 can be easily pulled out from input shaft.

[0034] In an embodiment of this utility model, the tensioner 42 of the drive mechanism 4 may further include a limiting rod 424 and a limiting connector 425. The tensioner 42 and the tensioning sleeve 422 are hollow structures. The limiting rod 424 moves through the tensioning sleeve 422 and the tensioning seat 421. The upper end of the limiting rod 424 forms a limiting stop 4241 for moving against the top of the tensioning sleeve 422. The lower end of the limiting rod 424 is connected to the limiting connector 425. The limiting connector 425 moves against the bottom of the tensioning seat 421. In this way, the limiting rod 424 and the limiting connector 425 can limit the tensioning seat 421 and the tensioning sleeve 422 to prevent them from separating. The return spring 423 can be sleeved on the limiting rod 424 to prevent the return spring 423 from shifting.

[0035] In an embodiment of this utility model, the lifting device 43 of the drive mechanism 4 may include a lifting seat 431, a lifting screw 432, and a lifting motor 433.

The lifting motor 433 can drive the lifting screw 432 through a synchronous belt transmission device 434. The drive motor 41 is mounted on the lifting seat 431 and lifts with the lifting seat 431.

[0036] In an embodiment of this utility model, the vibration detection mechanism 5 includes a suspended seat 51, a lifting cylinder 52, and a vibration sensor 53. The suspended seat 51 is installed on the machine base 1 and above the positioning fixture 31. The lifting cylinder 52 is installed on the suspended seat 51. The vibration sensor 53 is connected to the piston rod of the lifting cylinder 52. The lifting cylinder 52 and the vibration sensor 53 are electrically connected to the control host 2. After the control host 2 controls the tensioner 42 of the drive mechanism 4 to connect with the hollow rotating platform B, the control host 2 then controls the lifting cylinder 52 to drive the vibration sensor 53 down until the vibration sensor 53 contacts the hollow rotating platform B, so that the vibration sensor 53 can accurately detect the vibration of the hollow rotating platform B. After the vibration detection of the hollow rotating platform B is completed, the control host 2 then controls the lifting cylinder 52 to drive the vibration sensor 53 up to reset.

[0037] In an embodiment of this utility model, the displacement detection mechanism 6 includes a mounting base 61, a translational electric cylinder 62, and a displacement sensor 63. The mounting base 61 is mounted on the machine base 1 and located to the side of the positioning fixture 31. The translational electric cylinder 62 is mounted on the mounting base 61. The displacement sensor 63 is connected to the slide of the translational electric cylinder 62. The displacement sensor 63 and the translational electric cylinder 62 are electrically connected to the control host 2. After the control host 2 controls the tensioner 42 of the drive mechanism 4 to connect with the hollow rotating platform B, the control host 2 then controls the translational electric cylinder 62 to drive the displacement sensor 63 to move closer to the hollow rotating platform B, so that the displacement sensor 63 can accurately detect the displacement of the hollow rotating platform B. After the displacement detection of the hollow rotating platform B is completed, the control host 2 then controls the translational electric cylinder 62 to drive the displacement sensor 63 to reset.

[0038] In an embodiment of this utility model, the positioning fixture 31 of the mounting mechanism 3 is locked to the mounting platform 11 by bolts.

[0039] In an embodiment of this utility model, the pressing cylinder 325 of the mounting mechanism 3 can be installed on the bottom side of the mounting platform 11. The mounting platform 11 is provided with a clearance hole 112 for the piston of the pressing cylinder 325 to move. When the piston rod of the pressing cylinder 325 extends and retracts, it will drive the connecting seat 323 and the swing seat 322 to swing, thereby controlling whether the pressing seat 324 presses the hollow rotating platform B. The pressing seat 324 can be detachably connected to the first end of the connecting seat 323 through the pin 326, so that the pressing seat 324 is easy to install and remove.
