[0022] 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.
[0023] According to an embodiment of the present invention, a special fixture for machining a spindle box is provided.
[0024] like Figures 1-4As shown, a special fixture for machining a spindle box according to an embodiment of the present invention includes a metal rectangular support base 1. A pair of support columns 2 are fixedly installed on adjacent sides of the surface of the support base 1. A lifting groove 3 is opened on one side of the surface of the support column 2. A lifting screw 4 is rotatably installed inside the lifting groove 3. A transmission block 5 is threadedly connected to the surface of the lifting screw 4. The transmission block 5 is slidably installed in the lifting groove 3. A support rod 6 is fixedly connected to one side of the transmission block 5. An adjustment groove 7 is opened on one side of the surface of the support rod 6. A limit groove 8 is opened inside the adjustment groove 7. The limit groove 8 is located on both sides of its interior. A pair of sliding blocks 9 are slidably installed. A threaded cylinder 10 is fixedly connected to the top of the sliding blocks 9. An adjusting screw 11 is threadedly connected inside the threaded cylinder 10. One end of the adjusting screw 11 is rotatably connected to a clamping plate 12. By turning the adjusting screw 11, the clamping position of the clamping plate 12 can be adjusted. Positioning columns 13 are fixedly installed on the surface of the support base 1 on both sides corresponding to the support column 2. When the spindle box is placed on the surface of the support base 1, the two sides of its surface move to fit against one side of the two positioning columns 13, so as to achieve quick positioning of the spindle box before clamping.
[0025] like Figures 1-4 As shown, the top of the positioning column 13 has a rotating groove 14, and a positioning rod 15 is rotatably installed inside the rotating groove 14. An adjusting screw 16 is rotatably installed on the surface of the positioning rod 15, and a clamping plate 17 is rotatably connected to the end of the adjusting screw 16. By turning the adjusting screw 16, the clamping plate 17 moves up and down, thus clamping the top of the spindle box after the clamping plate 17 is adjusted. The top of the support rod 6 has a fixing groove 18, and a limiting screw 19 is rotatably installed on the top of the threaded cylinder 10. The limiting screw 19 is slidably installed in the fixing groove 18, and a limiting plate 20 is threadedly connected to the surface of the limiting screw 19. A pair of directional plates 21 are fixedly connected to both sides of the surface of the threaded cylinder 10, and the limiting plate 20 is slidably installed between the two directional plates 21 to limit the rotation of the limiting plate 20. After the threaded cylinder 10 slides to a suitable position in the adjusting groove 7, turning the limiting screw 19 causes the limiting plate 20 to move upward and press against the inner wall of the adjusting groove 7. This increases the friction between the limiting plate 20 and the support rod 6, preventing the threaded cylinder 10 from continuing to slide in the adjusting groove 7. The tops of the lifting screw 4, adjusting screw one 11, adjusting screw two 16, and limiting screw 19 are all fixedly connected to a turning disc 22 for easy adjustment of each screw. The bottom surfaces of the support column 2 and the positioning column 13 are fixedly connected to a mounting plate 23, which is bolted to the surface of the support base 1. One side surface of the clamping plate one 12 and the clamping plate two 17 has anti-slip textures 24 to increase the friction when they contact the spindle box. Positioning holes 25 are opened on both sides of the surface of the support base 1 for easy fixing of the support base 1 to the working point.
[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0027] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the spindle box is hoisted to the surface of the support base 1, so that the two sides of the surface of the spindle box are attached to one side of the two positioning posts 13 on the surface of the support base 1, realizing rapid positioning of the spindle box before clamping. After positioning, by turning the lifting screw 4 in the support post 2, the transmission block 5 drives the support rod 6 to move to a suitable height, and the clamping plate 12 is slid to the side of the corresponding spindle box surface through the adjustment groove 7. Then, the limit screw 19 is turned to position the threaded cylinder 10, and the adjustment screw 11 is turned to move the clamping plate 12 to the surface of the spindle box for compression clamping. The clamping plate 17 is rotated and moved to the top of the spindle box through the positioning rod 15. Then, the adjustment screw 16 is turned to move the clamping plate 17 downward to the top of the spindle box, thereby completing the stable clamping of the spindle box in all directions.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
