[0023] The technical scheme of the patent will be explained in further detail in combination with the specific embodiments.
[0024] Please refer to Figures 1-3 A clamping mechanism for CNC machining, comprising a clamping table 1, further comprising:
[0025] A plurality of regularly distributed clamping grooves 2 are formed on the clamping table 1;
[0026] A clamping block 3 is matched with the clamping groove 2, the clamping block 3 is provided with a mounting plate 5, the mounting plate 5 is rotatably provided with a rotating ring 8, the rotating ring 8 is provided with an extension rod 6, the extension rod 6 is fixedly connected with a driving frame 7, and the extension rod 6 is used for adjusting the height of the driving frame 7;
[0027] A positioning mechanism is arranged on the mounting plate 5 and used for positioning the extension rod 6;
[0028] A clamping mechanism is arranged on the driving frame 7 and used for clamping a workpiece.
[0029] The workpiece is placed in the middle of the clamping table 1, then the position of the clamping mechanism on the clamping table 1 is changed according to the shape of the workpiece, the clamping block 3 at the bottom of the mounting plate 5 is clamped into the corresponding clamping groove 2, the clamping block 3 is connected with the clamping table 1 through bolts, then the clamping angle of the clamping mechanism to the workpiece is adjusted by rotating the rotating ring 8, the rotating ring 8 is positioned by the positioning mechanism after adjustment, and then the workpiece can be clamped and fixed through the cooperation of the extension rod 6 and the clamping mechanism, so that the position of the entire clamping mechanism on the clamping table 1 can be adjusted according to the shape of the workpiece for CNC machining, in addition to being able to adapt to the clamping operation of workpieces of different sizes, the clamping angle and the clamping position of the clamping mechanism can also be adjusted according to the complex shape of the workpiece, and the practicability of the entire clamping mechanism is improved.
[0030] As an embodiment of the utility model, a plurality of positioning holes 18 corresponding to the clamping grooves 2 are formed at the bottom of the clamping table 1, and the bottom of the clamping block 3 is provided with a threaded hole 4 corresponding to the positioning hole 18.
[0031] The positioning hole 18 at the bottom of the clamping table 1 corresponding to the clamping groove 2 is used for conveniently putting in a bolt and screwing the bolt into the threaded hole 4 at the bottom of the clamping block 3, so that the clamping block 3 put into the clamping groove 2 can be fixedly connected with the clamping table 1, the clamping block 3 is fixed, that is, the positioning of the clamping mechanism on the driving frame 7 is realized, and according to the position of the clamping block 3 clamped into the clamping groove 2, the position of the driving mechanism on the clamping table 1 also changes correspondingly, so that the clamping mechanism is more flexible to use.
[0032] As an embodiment of the utility model, a placing table 17 is arranged at the middle of the clamping table 1.
[0033] The placement table 17 is located in the center of the clamping table 1, while the clamping mechanism is located around the placement table 17 and arranged around it. The workpiece to be clamped by the clamping mechanism is mainly placed on the placement table 17.
[0034] As an embodiment of the present invention, the positioning mechanism includes a hydraulic rod 11 mounted on the mounting plate 5, a positioning block 10 is mounted on one end of the hydraulic rod 11 near the rotating ring 8, and the outer wall of the rotating ring 8 is provided with a plurality of positioning grooves 9 that cooperate with the positioning block 10.
[0035] In this embodiment, in order to adjust the clamping angle of the clamping mechanism on the workpiece, the hydraulic rod 11 can be activated to retract it. During the retraction of the hydraulic rod 11, the positioning block 10 will be driven out of the positioning groove 9 of the rotating ring 8. At this time, the rotating ring 8 can be rotated, thereby changing the angle of the drive frame 7 through the telescopic rod 6. After the angle of the drive frame 7 is adjusted, the hydraulic rod 11 can be activated in reverse to extend it, thereby causing the positioning block 10 to re-enter the positioning groove 9 of the rotating ring 8, thus achieving the positioning of the rotating ring 8.
[0036] As an embodiment of the present invention, the clamping mechanism includes a threaded rod 12 rotatably disposed within the drive frame 7. A movable frame 13 that fits against the inner wall of the drive frame 7 is connected to the threaded rod 12. Connecting rods 15 are installed on both sides of the movable frame 13 located on the threaded rod 12. A clamping plate 16 is installed at the end of the connecting rod 15 away from the movable frame 13. A motor 14 is installed on the outer wall of the drive frame 7. The driving end of the motor 14 is connected to the threaded rod 12.
[0037] In this embodiment, after the position and angle of the clamping mechanism are adjusted, the motor 14 is started by the external control unit. The motor 14 drives the threaded rod 12 to rotate, thereby driving the moving frame 13 to move. The connecting rod 15 pushes the clamping plate 16 to move, so that the clamping plate 16 clamps the workpiece.
[0038] This invention places the workpiece on the placement table 17, then adjusts the position of the clamping mechanism on the clamping table 1 according to the shape of the workpiece, and inserts the locking block 3 at the bottom of the mounting plate 5 into the corresponding slot 2. The locking block 3 is then connected to the clamping table 1 by bolts. The clamping angle of the clamping mechanism on the workpiece is adjusted by rotating the rotating ring 8. After adjustment, the rotating ring 8 is positioned by the positioning mechanism. Then, with the cooperation of the telescopic rod 6 and the clamping mechanism, the workpiece can be clamped and fixed. Thus, the position of the entire clamping mechanism on the clamping table 1 can be adjusted according to the shape of the CNC machined workpiece. In addition to being able to adapt to the clamping operation of workpieces of different sizes, it can also adjust the clamping angle and clamping position of the clamping mechanism according to the complex shape of the workpiece, thereby improving the practicality of the entire clamping mechanism.
