Detailed Implementation
[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0021] Example 1 Reference Figure 1-4 The first embodiment of this utility model provides a positioning device for the production and processing of spline shafts, including a base 1 and two placement seats 2. The two placement seats 2 are respectively fixedly connected to the left and right sides of the top of the base 1. Two through holes 3 are opened on the left and right sides of the base 1. An extension structure 4 is provided inside the through holes 3. Lifting structures 5 are fixedly connected to the front and rear sides of the placement seats 2, and the lifting structures 5 correspond to the positions of the placement seats 2.
[0022] Specifically, spline shafts of different lengths can be placed using the extension structure 4, and then the placed spline shafts can be pressed using the lifting structure 5, thereby enabling the processing of the spline shafts.
[0023] Furthermore, after the spline shaft is placed on the mounting base 2, the extension structure 4 can be adjusted according to its length to support the spline shaft and prevent it from tilting during processing. Then, the spline shaft can be pressed by the lifting structure 5 to improve its stability.
[0024] Example 2 In the second embodiment of this utility model, the extension structure 4 includes two movable rods 401, an auxiliary frame 402, two square holes 403, and two blocks 404. The two movable rods 401 are slidably connected to the inside of the two through holes 3. The auxiliary frame 402 is fixedly connected to the side of the two movable rods 401 away from the base 1. The two square holes 403 are both opened on the surface of the auxiliary frame 402. The two blocks 404 are both fixedly connected to the side of the placement seat 2 near the auxiliary frame 402, and the positions of the blocks 404 and the square holes 403 correspond to each other. A cavity 6 is opened inside the block 404. A first electric cylinder 7 is arranged inside the cavity 6. Multiple slots 8 are equidistantly opened on the top of the movable rods 401. The output end of the first electric cylinder 7 is inserted into the inside of the slot 8.
[0025] Specifically, the use of extension structure 4 allows users to flexibly adjust according to different sizes of the spline shaft, and then the spline shaft can be supported by extension structure 4.
[0026] Furthermore, when it is necessary to stretch the auxiliary frame 402, the auxiliary frame 402 can be moved. When the auxiliary frame 402 moves, it slides in the through hole 3 inside the base 1 via the moving rod 401. When the auxiliary frame 402 moves to the appropriate position, the first electric cylinder 7 can be activated. The output end of the first electric cylinder 7 is inserted into the slot 8 at the top of the moving rod 401 to position the moving rod 401, thereby completing the positioning of the auxiliary frame 402.
[0027] Example 3 In the third embodiment of this utility model, the lifting structure 5 includes two placement frames 501, two second electric cylinders 502, two connecting plates 503, and a pressing seat 504. The two placement frames 501 are respectively fixedly connected to the front and rear sides of the placement seat 2. The two second electric cylinders 502 are respectively fixedly connected to the top of the two placement frames 501. The two connecting plates 503 are respectively fixedly connected to the output ends of the two second electric cylinders 502. The pressing seat 504 is disposed on the top of the placement seat 2, and both the front and rear sides of the pressing seat 504 are connected to the connecting plates 503. The surface of the receiving plate 503 is fixedly connected. The middle of the top of the pressing seat 504 is threaded with a screw 9. The top of the screw 9 is fixedly connected with a knob 10. The bottom of the screw 9 passes through and extends out of the bottom of the pressing seat 504. The bottom of the screw 9 is fixedly connected with an arc plate 11. The shape of the arc plate 11 matches the shape of the pressing seat 504. The arc plate 11 is opposite to the placement seat 2. The front and rear sides of the top of the placement seat 2 are fixedly connected with telescopic rods 12. The top of the telescopic rods 12 is fixedly connected to the bottom of the pressing seat 504.
[0028] Specifically, the spline shaft can be clamped by the clamping seat 504 to stably position it on the top of the placement seat 2, and then the spline shaft can be machined.
[0029] Furthermore, after the spline shaft is placed in the placement seat 2, the second electric cylinder 502 can be activated. The second electric cylinder 502 drives the connecting plate 503 to move down. When the connecting plate 503 moves, it drives the clamping seat 504 to move down, thereby clamping the spline shaft. Then the knob 10 can be rotated. After the knob 10 is rotated, it drives the screw 9 to move. The movement of the screw 9 can drive the arc plate 11 to move. Then the spline shaft can be clamped by the arc plate 11, thereby avoiding the gap between the spline shaft and the clamping seat 504.
[0030] Working principle: After placing the spline shaft in the mounting base 2, the auxiliary frame 402 can be moved when it is necessary to stretch it. When the auxiliary frame 402 moves, it slides in the through hole 3 inside the base 1 via the moving rod 401. When the auxiliary frame 402 moves to the appropriate position, the first electric cylinder 7 can be activated. The output end of the first electric cylinder 7 is inserted into the slot 8 at the top of the moving rod 401 to position the moving rod 401, thereby completing the positioning of the auxiliary frame 402. Then, the second electric cylinder 502 can be activated. The second electric cylinder 502 drives the connecting plate 503 to move down. When the connecting plate 503 moves, it drives the clamping seat 504 to move down, thereby clamping the spline shaft. Then, the knob 10 can be rotated. After the knob 10 is rotated, it drives the screw 9 to move. The movement of the screw 9 can drive the arc plate 11 to move, and then the spline shaft can be clamped by the arc plate 11, thereby avoiding gaps between the spline shaft and the clamping seat 504.
[0031] In summary, by using the combination of base 1, placement seat 2, through hole 3, extension structure 4, moving rod 401, auxiliary frame 402, square hole 403, block 404, lifting structure 5, placement frame 501, second electric cylinder 502, connecting plate 503, clamping seat 504, cavity 6, first electric cylinder 7, slot 8, screw 9, knob 10, arc plate 11, and telescopic rod 12, the problem of spline shafts potentially shifting during processing if not clamped and positioned is solved, thus affecting the processing of spline shafts.
