[0015] 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.
[0016] Please refer to Figures 1-3. This utility model provides a technical solution: a non-loosening spindle motor fixing plate, including a fixing mechanism 1 installed on a CNC machine tool and a spindle motor 2 installed inside the fixing mechanism 1. The fixing mechanism 1 includes a base plate 101 and a vertical plate 102 welded to the top of the base plate 101. Specifically, the coaxiality of the spindle motor 2 and the spindle is ensured by the fixing mechanism 1.
[0017] In Figures 1-6: The top of the base plate 101 is provided with a mounting mechanism 3 that is sleeved on the outside of the spindle motor 2. The mounting mechanism 3 is used to realize the quick installation of the spindle motor 2 on the spindle motor fixing plate. The mounting mechanism 3 includes a support plate 301 welded to the top wall of the base plate 101 and a flip plate 302 hinged to the top of the support plate 301. The front ends of the support plate 301 and the flip plate 302 are respectively fixed with a movable plate 303 and a fixed plate 304. The middle of the front end of the fixed plate 304 is provided with a positioning groove 306. The bottom end of the movable plate 303 is threadedly connected with a threaded connector 305 that forms a locking structure with the positioning groove 306. The threaded connector 305 and the positioning groove 306 cooperate to realize the positioning between the movable plate 303 and the fixed plate 304.
[0018] Specifically, the output shaft of the spindle motor 2 passes through the vertical plate 102, and the spindle motor 2 is placed on the top of the support plate 301. At this time, since the flip plate 302 and the support plate 301 are rotatably connected by the hinge, the flip plate 302 can be flipped by moving the movable plate 303 until the flip plate 302 and the support plate 301 are closed. At this time, the threaded connector 305 is aligned with the positioning groove 306. Then, by rotating the threaded connector 305, it is locked into the positioning groove 306, thereby realizing the quick installation of the spindle motor 2 on the spindle motor fixing plate.
[0019] In Figures 1, 2 and Figure 4 - In Figure 6: The threaded connector 305 includes a threaded post and a handle, and the surface of the handle is provided with anti-slip protrusions to increase friction.
[0020] Specifically, by incorporating anti-slip protrusions, the friction between the hand and the handle can be increased, preventing slippage and improving the ease of rotating the handle.
[0021] In Figures 1-3: elastic pads 5 are provided at the ends of the pallet 301 and the flip plate 302 that are close to each other, and the elastic pads 5 are made of natural rubber.
[0022] Specifically, the elastic pad 5 protects the spindle motor 2 and prevents hard contact damage between the spindle motor 2 and the support plate 301 and the tilting plate 302.
[0023] In Figures 1, 2, 4 and Figure 6 In the middle: The top of the inner side of the movable plate 303 is provided with an anti-loosening mechanism 4 to prevent loosening and displacement caused by vibration. The anti-loosening mechanism 4 includes a cylinder 402 that is slidably connected to the movable plate 303 and an anti-loosening groove 405 opened at the front end of the threaded connector 305. An anti-loosening plate 401 that is rotatably connected to the cylinder 402 via a rotating shaft is engaged inside the anti-loosening groove 405. The anti-loosening plate 401 and the anti-loosening groove 405 cooperate to prevent the threaded connector 305 from loosening. A return spring 404 sleeved on the outside of the guide rod 403 is connected between the cylinder 402 and the movable plate 303. The return spring 404 is used to realize the automatic reset of the anti-loosening plate 401.
[0024] Specifically, since the cylinder 402 and the movable plate 303 are elastically connected by the return spring 404, the return spring 404 can be stretched by pulling the anti-loosening plate 401 outward. Since the anti-loosening plate 401 is rotatably connected to the cylinder 402, it can be aligned with the anti-loosening groove 405 by rotating the anti-loosening plate 401. At this time, the anti-loosening plate 401 is released, so that it is locked into the anti-loosening groove 405, thereby locking the threaded connection 305, avoiding loosening and displacement caused by vibration, and helping to extend the service life.
[0025] exist Figure 4 In Figure 6, a guide rod 403, which is welded to the movable plate 303, is slidably connected to the rear end of the inner side of the cylinder 402 to support and limit the movement of the cylinder 402. Specifically, since the cylinder 402 and the movable plate 303 are slidably connected through the guide rod 403, the guide rod 403 can support and limit the movement of the cylinder 402 to prevent displacement, and at the same time, the guide rod 403 supports the return spring 404 to prevent tilting.
[0026] The output shaft of the main spindle motor 2 passes through the vertical plate 102, and the main spindle motor 2 is placed on the top of the support plate 301. At this time, the rotating plate 302 is flipped by moving the movable plate 303 until the rotating plate 302 and the support plate 301 are closed. Then, the threaded connector 305 is rotated to lock into the positioning groove 306, thereby realizing the quick installation of the main spindle motor 2 on the main spindle motor fixing plate. At this time, the anti-loosening plate 401 is pulled outward to stretch the return spring 404. After rotating the anti-loosening plate 401 to align with the anti-loosening groove 405, the anti-loosening plate 401 is released, so that it locks into the anti-loosening groove 405, thereby locking the threaded connector 305, preventing vibration from causing loosening and displacement, and helping to extend the service life. The electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source and controlled by a control box. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
