Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figure 1-5As shown, the positioning structure of the switchable output threaded shaft includes a base 1, a positioning seat 2 and a switching seat 3. The positioning seat 2 is connected to the base 1. The switching seat 3 is detachably connected to the positioning seat 2 through a movable rod 4, forming two positioning connection positions, so that the switching seat 3 is placed inside the positioning seat 2 or extends out of the positioning seat 2. The end of the switching seat 3 that extends out of the positioning seat 2 is detachably connected to the output threaded shaft 5.
[0018] The positioning structure of this utility model is simple. Through the cooperative design of the switching seat 3, the positioning seat 2, and the output threaded shaft 5, it is possible to flexibly replace the output threaded shaft 5 of different specifications, thereby switching and assembling different specifications of threads in real time, realizing the diverse assembly of threads, reducing operational errors and mismatch of parts threads caused by frequent changes of positioning fixtures, significantly improving work efficiency and reducing costs.
[0019] Furthermore, the positioning seat 2 is provided with a through hole 201, one end of which extends outward to form a connecting post 202. The base 1 is provided with a mounting hole 101 for mounting the connecting post 202. The positioning seat 2 is also provided with a slide 203 for moving the movable rod 4, and the slide 203 communicates with the through hole 201. The two ends of the slide 203 form two first positioning grooves 204 and second positioning grooves 205 for locking the movable rod 4, and the two positioning grooves are arranged parallel to each other. One end of the movable rod 4 is connected to the switching seat 3, and the movable rod 4 drives the switching seat 3 to move along the through hole 201. The switching seat 3 is provided with a first connecting groove 301 and a second connecting groove 302. The output threaded shaft 5 is connected in the first connecting groove 301, and one end of the movable rod 4 passes through the slide 203 and is connected in the second connecting groove 302, and the second connecting groove 302 is laterally located below the first connecting groove 301.
[0020] In the above design, the slide 203 is used to limit the movement of the movable rod 4, and is then fixedly connected to the second connecting groove 302 at the positions of the two positioning grooves 205 via the movable rod 4. This facilitates the limited movement of the switching seat 3 and ensures stable positioning, thereby improving the connection stability of the entire positioning structure. The positioning seat 2 is connected to the mounting hole 101 of the base 1 via the connecting column 202. The specific fixing method can be selected according to the needs of the positioning structure, and conventional fixing methods in existing designs can be flexibly adopted. The specific connection method between the output threaded rod 5 and the first connecting groove 301 can also be flexibly selected according to the structure of the output threaded rod 5, and will not be elaborated here.
[0021] Furthermore, the slide 203 includes a first straight track and a second straight track formed by bending the first straight track, and the first and second straight tracks are parallel to each other. A first positioning groove 204 is located at one end of the first straight track, and a second positioning groove 205 is located at one end of the second straight track, with the second positioning groove 205 positioned above the first positioning groove 204. The movable rod 4 is a cylindrical head hexagonal screw, and its thread is connected to the second connecting groove 205. The above design facilitates the movement of the movable rod 4 along the straight track and drives the switching seat 3 to rotate along the output threaded rod 5, realizing the switching between the two straight tracks. The position of the movable rod 4 is then fixed by the two positioning grooves. The specifications of the slide 203 and the switching seat 3 can be flexibly designed according to actual usage requirements. The selection of a cylindrical head hexagonal screw as the movable rod 4 is convenient in material selection and simple in operation. The two cross sections of the slide 203 are square, which facilitates the movement of the cylindrical head hexagonal screw. The two positioning grooves are arc-shaped grooves, which can stably lock and fix the cylindrical head hexagonal screw.
[0022] In use, first fix the positioning seat 2 to the base 1, then insert the switching seat 3 through the through hole 201 of the positioning seat 2, so that the switching seat 3 is placed at the bottom of the through hole 201. At this time, the second connecting groove 302 on the switching seat 3 is opposite to the first positioning groove 204. Then, the movable rod 4 is passed through in sequence to complete the initial connection between the switching seat 3 and the positioning seat 2. The output threaded shaft 5 is pre-fitted into the through hole 201. Figure 2 and 4 As shown; then, the movable rod 4 drives the switching seat 3 to move along the first straight track. When the first connecting groove 301 on the switching seat 3 fits onto the bottom end of the output threaded shaft 5, the movable rod 4 is located at the bend of the first and second straight tracks. Rotate the movable rod 4 to drive the switching seat 3 to rotate along the output threaded shaft 5, completing the connection between the switching seat 3 and the output threaded shaft 5. When the movable rod 4 rotates to the position of the second straight track, it finally moves down to the position of the second positioning groove 205. Tighten the movable rod 4 to complete the installation of the output threaded shaft 5. When it is necessary to replace the output threaded shaft 5, first loosen the movable rod 4, then drive the switching seat 3 to move and turn, so that the switching seat 3 is disengaged from the output threaded shaft 5. Finally, return the switching seat to the first positioning groove 204.
[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
