The hydraulic rod 6 controls the lifting and lowering of the forming plate 7 by telescopic movement, thereby cooperating with the auxiliary component 3 to complete the forming of the aviation composite material flat plate, and the forming plate 7 is installed at the output end of the hydraulic rod 6. End plates 9 are installed on the left and right ends of the processing table 1, and hydraulic rods 3 10 are installed on the surface of the end plates 9. The hydraulic rods 3 10 control the alternating movement of the auxiliary component 3 on the processing table 1 by telescopic movement, so that the two groups of auxiliary components 3 cooperate with the forming plate 7 to work alternately to increase work efficiency.

[0023] like Figure 2As shown, the auxiliary components 3 for assisting the workpiece positioning are arranged on both sides of the upper end of the processing table 1, and the auxiliary components 3 include side plates 301, adjustment grooves 302, auxiliary plates 303, double-threaded screw rods 304, limiting rings 305 and auxiliary rods 306. The surface of the side plate 301 is provided with an adjustment groove 302. The adjustment groove 302 on the side plate 301 allows the auxiliary plate 303 to move to a stable position, and the auxiliary plate 303 is arranged inside the adjustment groove 302. The auxiliary plate 303 plays a role in side clamping and positioning workpieces of different sizes when approaching, thereby increasing the accuracy of subsequent molding processing. The double-threaded screw rod 304 is installed on the inner side of the end of the auxiliary plate 303. 304 is driven to rotate by a motor, so that the two auxiliary plates 303 are moved closer or farther away from the outside of the double-threaded screw rod 304, and a limit ring 305 is installed on the side of the auxiliary plate 303 by screws. The limit ring 305 is also adjusted according to the size of the workpiece. An auxiliary rod 306 is arranged inside the limit ring 305. The limit ring 305 and the auxiliary rod 306 are symmetrically arranged in two groups about the center line of the auxiliary plate 303, and the limit ring 305 and the auxiliary rod 306 are sleeved. The limit ring 305 is sleeved on the outside of the auxiliary rod 306, so that the auxiliary rod 306 moves in the limit ring 305 when the auxiliary plate 303 approaches. At this time, the auxiliary rod 306 further positions the workpiece.

[0024] like Figure 3 As shown, a limit assembly 8 for limiting the auxiliary component 3 is provided on the side of the forming platen 7, and the number of the limit assembly 8 is set in two groups, the limit assembly 8 includes a hydraulic rod 801 and a mounting plate 802, the hydraulic rod 801 controls the position adjustment of the rotating rod 803 and the limit plate 804 by telescopic control, and the side of the fixed end of the hydraulic rod 801 is installed with a mounting plate 802, the limit assembly 8 also includes a rotating rod 803 and a limit plate 804, the output end of the hydraulic rod 801 is installed with a rotating rod 803 through a motor, and the end of the rotating rod 803 is installed with a limit plate 804, the rotating rod 803 and the limit plate 804 are vertically distributed, and the shape of the limit plate 804 is rectangular, and when the limit plate 804 rotates to a vertical state, it limits the side of the auxiliary component 3, so that the auxiliary component 3 is better positioned with the forming platen 7.

[0025] In summary, the aviation composite flat plate forming tooling is first based on Figure 1-Figure 3In the structure shown in the figure, the material is placed flat on the side plate 301, and the motor is turned on according to the size of the material, so that the double-threaded screw rod 304 rotates and drives the two auxiliary plates 303 to approach the side of the material workpiece outside the double-threaded screw rod 304. At this time, the auxiliary plates 303 play a role in side clamping and positioning workpieces of different sizes when approaching, thereby increasing the accuracy of subsequent forming processing. At the same time, the limiting ring 305 is adjusted on the side of the auxiliary plate 303 according to the size of the workpiece, so that the auxiliary rod 306 moves in the limiting ring 305 when the auxiliary plate 303 approaches. At this time, the auxiliary rod 306 further positions the workpiece position, and then the auxiliary component 3 on one side is pushed to the bottom of the forming plate 7 for processing and forming through the extension of the hydraulic rod three 10. When moving, the hydraulic rod two 801 is controlled by telescopic The position of the rotating rod 803 and the limit plate 804 is adjusted. At the same time, when the limit plate 804 is rotated to a vertical state under the drive of the motor at the end of the rotating rod 803, it limits the side of the auxiliary component 3. During molding, the hydraulic rod 1 6 controls the lifting and lowering of the molding plate 7 by telescoping to cooperate with the auxiliary component 3 to complete the molding of the aviation composite material flat plate. During molding, the stabilizer bar 5 slides in the top hole 4 to increase the stability of the molding plate 7, so that the auxiliary component 3 can be better positioned with the molding plate 7. After the material in a single auxiliary component 3 is processed, the hydraulic rod 3 10 retracts, and the other group of hydraulic rods 3 10 extends to push the other group of auxiliary components 3 under the molding plate 7. At this time, the auxiliary components 3 move alternately on the processing table 1, so that the two groups of auxiliary components 3 can cooperate with the molding plate 7 to work alternately to increase work efficiency.
