By making a thin plate positioning tooling, the reliability and stability of thin plate positioning are improved, different degrees of freedom are restricted, and the processed thin plate has better straightness and parallelism.

[0003] Currently, when processing thin plates, generally, pressing blocks are used to fix both sides of the thin plate. During the machining process, affected by the interaction between the cutting tool and the thin plate and the feed rate during machining, the thin plate will move backward, the straightness error is relatively large, and the parallelism between the two plate surfaces cannot be guaranteed within a relatively accurate dimension. Especially when processing thin plates with a relatively small thickness, the straightness of one side of the plate and the parallelism with both sides cannot meet the usage requirements.

[0004] To solve the above problems, this application designs and manufactures a tooling dedicated to positioning thin plates with different length dimensions to solve the existing problems. Utility Model Content

[0031] In machining, when processing thin plates, the positioning of thin plates is one of the most important steps. For working conditions with relatively strict machining dimensional accuracy and long thin plate lengths, currently, press plates are used to position thin plates during machining. By fabricating a thin plate positioning tooling, the reliability and stability of thin plate positioning can be improved, different degrees of freedom can be restricted, and the processed thin plates have better straightness and parallelism. Currently, when processing thin plates, generally, clamping blocks are used to fix both sides of the thin plate. During the machining process, affected by the interaction between the cutting tool and the thin plate and the feed rate during machining, the thin plate may move backward, with a large straightness error, and the parallelism between the two plate surfaces cannot be guaranteed to be within a relatively precise dimension. Especially when processing thin plates with a relatively small thickness, the straightness of one side of the plate and the parallelism with both sides cannot meet the usage requirements. To solve the above problems, this application designs and fabricates a tooling dedicated to positioning thin plates with different length dimensions to solve the existing problems.

[0032] In view of this, the thin plate positioning device provided in this application includes a positioning plate and at least two movable press plates; the movable press plate has a pressing portion, the edge of the pressing portion is aligned with the edge of the positioning plate, and the movable press plate is movably connected to the positioning plate so that the pressing portion can rise or fall to press against the thin plate to be processed. In the thin plate positioning device provided in this application, during the process of processing a thin plate, the side of the positioning plate provided with the movable press plates is covered on the thin plate to be processed. Due to at least two movable press plates pressing against the thin plate to be processed along the length direction of the thin plate, it effectively avoids the problems that during the machining process, the thin plate is affected by the interaction between the cutting tool and the thin plate and the feed rate during machining, resulting in the thin plate moving backward and the thin plate bending, leading to a large straightness error and the parallelism between the two plate surfaces not being guaranteed to be within a relatively precise dimension. Pressing the thin plate at multiple points effectively ensures the stability of machining, and thus ensures the machining accuracy.

[0033] Please refer to Figures 1 to 4 , the thin plate positioning device 10 provided in the embodiment of this application includes a positioning plate 11 and at least two movable press plates 13; the movable press plate 13 has a pressing portion 131, the edge of the pressing portion 131 is aligned with the edge of the positioning plate 11, and the movable press plate 13 is movably connected to the positioning plate 11 so that the pressing portion 131 can rise or fall to press against the thin plate to be processed.

[0034] The thin plate positioning device 10 provided by the present application, during the process of processing a thin plate, covers the side of the positioning plate 11 with the movable pressing plate 13 on the thin plate to be processed. Due to at least two movable pressing plates 13, they are pressed against the thin plate to be processed along the length direction of the thin plate, thereby effectively avoiding the problems that during the processing, the thin plate will move backward and the thin plate will bend due to the interaction between the cutting tool and the thin plate and the influence of the feed rate during processing, resulting in a large straightness error and the parallelism of the two plate surfaces cannot be guaranteed within a relatively precise dimension. Pressing the thin plate at multiple points effectively ensures the stability of processing, and thus ensures the processing accuracy.

By means of the telescopic adjusting nut 151, the connecting portion 132 rises or falls relative to the positioning plate 11, and thus the pressing portion 131 falls or rises relative to the positioning plate 11.

During use, by the combined use of the tension screw 15 and the telescopic adjusting nut 151, the connecting portion 132 can rise or fall relative to the positioning plate 11, and thus the pressing portion 131 falls or rises relative to the positioning plate 11, so as to realize that the pressing portion 131 presses against the thin plate to be processed with different thicknesses.

[0037] Specifically, in an optionally exemplary embodiment, first threaded holes 111 matching the tension screw 15 are provided at corresponding positions of the movable pressing plate 13 and the positioning plate 11, and the tension screw 15 sequentially penetrates through the positioning plate 11 and the movable pressing plate 13; the telescopic adjusting nut 151 is sleeved on the tension screw 15 and is disposed on the side of the positioning plate 11 away from the movable pressing plate 13.

[0038] It should be noted that specifically, in this embodiment, with such a setting, during use, by the combined use of the tension screw 15 and the telescopic adjusting nut 151, the connecting portion 132 can rise or fall relative to the positioning plate 11, and thus the pressing portion 131 falls or rises relative to the positioning plate 11, so as to realize that the pressing portion 131 presses against the thin plate to be processed with different thicknesses.

[0040] It should be noted that specifically, in this embodiment, the fixing screw 17 is provided, and an end of the connecting portion 132 of the movable pressing plate 13 is provided with a second threaded hole adapted to the fixing screw 17.

When the pressing portion 131 can be raised or lowered relative to the positioning plate 11 to a preset height by the cooperation of the stretching screw 15 and the telescopic adjusting nut 151, the fixing screw 17 is tightened to lock the stretching screw 15, thereby keeping the pressing portion 131 at the preset height.

[0043] Meanwhile, the pressing portion 131 of the movable pressing plate 13 is a convex platform provided on the movable pressing plate 13, and the convex platform protrudes from the movable pressing plate groove 112. The convex platform can realize multi-point pressing against the thin plate to be processed, thereby realizing the stability of processing.

[0048] Specifically, a connecting piece 133 is provided on each side of the movable platen 13, and the two connecting pieces 133 are symmetrically arranged. In this way, the stability of the connection between the movable platen 13 and the positioning plate 11 is effectively ensured.

[0049] Specifically, the connecting piece 133 is arranged at a position close to the middle of the movable platen 13. In this way, the connecting part 132 and the pressing part 131 of the movable platen 13 can move with the connecting piece 133 as the fulcrum, and then by adjusting the rise or fall of the connecting part 132, the rise or fall of the pressing part 131 can be adjusted.
