Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-3 The utility model provides a technical solution: a high-speed stability single-axis test turntable, including a turntable base 1, a rotating shaft 2 is arranged on the top of the turntable base 1, a placing table 3 is fixedly connected to the top of the rotating shaft 2, a fixing device 4 is arranged at an equal angle on the top of the placing table 3, a reinforcing device 5 is arranged in the gap of the fixing device 4, and the fixing device 4 cooperates with the reinforcing device 5 to stably clamp and fix the equipment. The rotating shaft 2 is arranged on the top of the turntable base 1, so as to drive the placing table 3 to rotate. Since the fixing devices 4 are arranged at equal angles on the surface of the placing table 3, multiple fixing devices 4 cooperate to stably fix the object and improve the stability during the rotation process. At the same time, the reinforcing device 5 is arranged in the gap of the fixing device 4, so that the placing table 3 can further squeeze and fix the object while rotating, improve the stability of the object fixation, and facilitate the operation of the staff.

[0024] There are six fixing devices 4 and six reinforcing devices 5. Multiple fixing devices 4 cooperate with reinforcing devices 5 to stably fix the object and improve the stability during the rotation process.

[0025] The fixing device 4 includes a fixing block 41, a threaded rod 42, a rotating block 43 and an extrusion block 44. The fixing block 41 is fixedly connected to the top of the placing table 3. The fixing block 41 is threadedly connected to the threaded rod 42. The end of the threaded rod 42 is fixedly connected to the rotating block 43. The end of the threaded rod 42 away from the rotating block 43 is fixedly connected to the extrusion block 44. The fixing device 4 is provided to facilitate the extrusion and fixation of the object. The rotating block 43 is rotated to drive the threaded rod 42 to rotate, and the extrusion block 44 is driven to move. The six extrusion blocks 44 cooperate with each other, so as to extrude and fix objects of different specifications.

[0026] Among them, a rubber pad is provided at the end of the extrusion block 44. The rubber pad is provided to improve the protection of the object.

[0027] Among them, the reinforcement device 5 includes a fixed frame 51, an extrusion rod 52, a contact block 53, a stopper 54, a connecting block 55, a guide wheel 56, a traction rope 57, a metal fixing sleeve 58 and a metal block 59. The fixed frame 51 is slidably connected to the extrusion rod 52, the end of the extrusion rod 52 is fixedly connected to the contact block 53, the end of the extrusion rod 52 away from the contact block 53 is fixedly connected to the stopper 54, the surface of the extrusion rod 52 is fixedly connected to the connecting block 55, the surface of the fixed frame 51 is fixedly connected to the guide wheel 56, the surface of the connecting block 55 is fixedly connected to the traction rope 57, the traction rope 57 is slidably connected to the guide wheel 56, the traction rope 57 is slidably connected to the fixed frame 51, the end of the traction rope 57 located inside the fixed frame 51 is fixedly connected to the metal fixing sleeve 58, and the metal fixing sleeve 58 is fixedly connected to the metal block 59. A reinforcement device 5 is provided. When the placement table 3 rotates, the metal block 59 generates an outward centrifugal force, which drives the metal fixing sleeve 58 to move, drives the traction rope 57 to move, pulls the connecting block 55, drives the extrusion rod 52 to move toward the center of the placement table 3, drives the contact block 53 to move, thereby squeezing the object. The faster the placement table 3 rotates, the greater the squeezing force on the object, further improving the fixation stability of the object.
