DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a limiting fixture for a thread ring gauge includes an upper fixing plate 1 for placing and supporting the go gauge and no-go gauge of the thread ring gauge. The bottom end of the upper fixing plate 1 is fixedly connected to a lower fixing plate 2 through a fixing shaft 9. Inside the upper fixing plate 1, at the top, and inside a rotating ring 3, there is a clamping mechanism movably connected for limiting and clamping the thread ring gauge. A rotating mechanism is installed on the outer periphery, at the top of the clamping mechanism, and at the top of the upper fixing plate 1; the clamping mechanism moving outward is used to drive the rotating mechanism to rotate and open, and the clamping mechanism moving inward is used to drive the rotating mechanism to block the top of the clamping mechanism.
[0021] In this embodiment: when the go gauge and no-go gauge are not in use, stack the go gauge and no-go gauge vertically on the top center of the upper fixing plate 1. Then, apply a force to the outer periphery of the rotating ring 3 to make the rotating ring 3 rotate. The rotating ring 3 drives the clamping mechanism to limit the placed go gauge and no-go gauge. At the same time, during the movement of the clamping mechanism, the rotating mechanism rotates simultaneously to block the upper part of the placed go gauge and no-go gauge.
[0022] Please refer specifically to Figure 1 and Figure 2 , the clamping mechanism includes an axial chute 4 opened at the top end of the upper fixing plate 1 and recessed downward. An arc-shaped groove 12 recessed downward is opened at the top of the lower fixing plate 2. The inner wall of the arc-shaped groove 12 is movably connected to a movable column 13 extending to the inner wall of the axial chute 4. The top of the movable column 13 is fixedly connected to a clamping rod 6, and the clamping rod 6 is located above the upper fixing plate 1.
[0023] In this embodiment: by rotating the rotating ring 3, the rotating ring 3 drives the arc-shaped groove 12 to rotate synchronously. The rotating arc-shaped groove 12 squeezes the movable column 13. The stressed movable column 13 moves along the axial chute 4. At this time, the movable column 13 drives the clamping rod 6 at its top to move synchronously until the outer periphery of the clamping rod 6 contacts the outer walls of the no-go gauge and go gauge, placing and limiting the no-go gauge and go gauge, and avoiding the problem that the no-go gauge and go gauge are separated due to force and are not easily paired.
[0024] Please refer specifically to Figure 3 and Figure 4 , the rotating mechanism includes a limiting ring 15 rotatably connected to the outer periphery of the movable column 13. A limiting groove 14 is opened in the upper fixing plate 1 along the direction of the axial chute 4. The inner cavity of the limiting groove 14 is communicated with the inner cavity of the axial chute 4. The rotating mechanism further includes a tooth block 7 integrally formed below the outer periphery of the clamping rod 6. A rack 5 is fixedly connected to the top of the upper fixing plate 1. The rack 5 and the tooth block 7 cooperate to drive the moving clamping rod 6 to rotate by 90 degrees. A limiting rod 8 is fixedly connected to the top of the clamping rod 6.
[0025] In this embodiment: When the clamping mechanism moves, the clamping rod 6 drives the tooth block 7 on its outer periphery to move synchronously. The moving tooth block 7 meshes with the rack 5. Since the tooth block 7 is fixed, the tooth block 7 drives the clamping rod 6 to rotate under force. Since the number of teeth on the rack 5 is half of the total number of tooth blocks 7, the clamping rod 6 rotates 90 degrees. The rotating clamping rod 6 drives the limit rod 8 on its top to rotate 90 degrees. After the four limit rods 8 rotate 90 degrees, they are in a "cross" shape, covering the top space of the go - gauge and the no - go - gauge, preventing the separation of the no - go - gauge and the go - gauge caused by the device tipping over, and thus avoiding the problem of difficult pairing.
[0026] Please refer specifically to Figure 2 , annular grooves 10 are provided at the top and bottom of the rotating ring 3 and at the bottom of the upper fixed disk 1 and the top of the lower fixed disk 2. Ball bearings 11 are rollingly connected to the inner sides of the annular grooves 10.
[0027] In this embodiment: When the rotating ring 3 rotates, the ball bearings 11 can effectively reduce the frictional force suffered by the rotating ring 3 during rotation.
[0028] Please refer specifically to Figure 3 , the outer periphery of the fixed shaft 9 is rotationally connected to the inner periphery of the rotating ring 3.
[0029] In this embodiment: A hole groove matching the fixed shaft 9 is provided at the center of the rotating ring 3, facilitating the rotation of the rotating ring 3, while the fixed shaft 9 and the upper fixed disk 1 and the lower fixed disk 2 on its top remain stationary.
[0030] The above - mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
