[0026] Please refer to Figure 2 , the pressing piece 7 comprises a telescopic moving piece 71 with external threads and a turntable 72 and a lower pressing plate respectively installed on the upper and lower ends of the telescopic moving piece 71; the telescopic moving piece 71 is screwed on the turnover pressing plate 3, the turntable 72 is rotated to make the telescopic moving piece 71 with the lower pressing plate move up and down, and in the process of the telescopic moving piece 71 with the lower pressing plate moving down, the processed material can be pressed on the top of the processing table 1.

[0027] Please refer to 2、 Figure 5 、 Figure 6 and Figure 7The lower pressure plate includes a pressure head 73, with guide grooves 736 on both sides of the pressure head 73. A guide block 732 is slidably inserted into the guide groove 736, and an installation block 731 is installed on the outer end of the guide block 732. The installation block 731 can move horizontally on the side wall of the pressure head 73 by sliding the guide block 732 in the inner cavity of the guide groove 736 (the installation block 731 can move closer to or further away from the pressure head 73). A connecting rod is installed on the bottom wall of the installation block 731. The end is hinged to a contact member 733 (the contact member 733 refers to a flat plate) via a pivot. An elastic member 734 is provided between the contact member 733 and the mounting block 731. A slot 7311 is provided at the bottom of the mounting block 731, which is located on the outside of the connecting rod. A movable block 735 is slidably inserted in the slot 7311 (the movable block 735 can move up and down in the slot 7311). The bottom wall of the movable block 735 is in contact with the top wall of the contact member 733.

[0028] The movable block 735 is equipped with a pull rope 7323 connected to the guide block 732. This rope 7323 is used to ensure that the guide block 732 can move outward from the guide groove 736 during the movement of the movable block 735. Specifically, an elastic element 737 is provided between the guide groove 736 and the guide block 732 to push the guide block 732 to move outward from the guide groove 736. Several sets of limiting grooves 738 are provided in the guide groove 736, and the sets of limiting grooves 738 are arranged along the moving direction of the guide block 732. An installation groove 7322 is provided on the guide block 7322, and a limiting block 7321 is slidably provided in the installation groove 7322. A spring is installed between the limiting block 7321 and the installation groove 7322. The end of the limiting block 7321 away from the guide block 732 is inserted into the inner cavity of the limiting groove 738. The end of the pull rope 7323 away from the movable block 735 is connected to the limiting block 7321.

[0029] In this embodiment, as a further optimization, please refer to... Figure 6 and Figure 7 The inlet area of ​​the limiting groove 738 is larger than the end area of ​​the limiting block 7321, so that after the pull rope 7323 disappears from the action of the limiting block 7321, the limiting block 7321 can be inserted into other limiting grooves 738 (the inlet area of ​​the limiting groove 738 is larger than the end area of ​​the limiting block 7321, which means that the limiting block 7321 has a greater chance of being inserted into the limiting groove 738), ensuring that the position of the mounting block 731 and the contact member 733 can be fixed; the bottom of the contact member 733 is provided with a ball 7331, which is used to reduce the friction between the contact member 733 and the material, making it convenient for the mounting block 731 to move with the contact member 733.

[0030] Please see Figure 7A touch switch 7312 is provided within the slot 7311. The touch switch 7312 is located above the movable block 735 and is electrically connected to the telescopic moving member 71. The telescopic moving member 71 includes a moving rod 711 and a movable rod 712. An opening is provided at the bottom of the moving rod 711, and the movable rod 712 is slidably inserted into the opening. A telescopic mechanism 713 is provided on the moving rod 711 (the telescopic mechanism 713 refers to an electrically driven telescopic rod, hydraulic or pneumatic telescopic rod, etc.). (In preparation), the moving end of the telescopic mechanism 713 is connected to the movable rod 712 to drive the movable rod 712 to move up and down; the telescopic mechanism 713 is electrically connected to the touch switch 7312 via a wire (the touch switch 7312 is electrically connected to the power supply of the telescopic mechanism 713 to control the telescopic mechanism 713 to be energized); the end of the movable rod 712 away from the moving rod 711 is rotatably connected to the pressure head 73, so that the pressure head 73 can rotate below the telescopic movable member 71 to adjust the angle of the pressure head 73.

[0031] It should be noted that the working method of the processing clamping assembly is as follows: the material to be processed is placed above the processing table 1, the flipping pressure plate 3 is rotated to move the pressing part 7 above the material to be processed; then the limiting part 4 is rotated to restrict the flipping pressure plate 3 (preventing it from rotating); then the turntable 72 is rotated so that the telescopic moving part 71 moves down with the lower pressure plate to contact the upper part of the material to be processed, and the material is fixed above the processing table 1 before processing; after processing is completed, the fixing of the material to be processed is removed (there are two ways to remove the fixing: first, rotate the turntable 72 so that the telescopic moving part 71 moves up with the lower pressure plate to avoid contact with the material to be processed, and then rotate the limiting part 4 (to release the restriction on the flipping pressure plate 3) to flip the flipping pressure plate 3 outward; second, directly rotate the limiting part 4 to flip the flipping pressure plate 3 outward and remove the pressing part 7 from above the material to be processed), and the material to be processed is removed from the processing table 1.

[0032] It should also be noted that when the fixed material is hollow and the pressure exerted by the lower pressure plate on the material is too great, causing it to dent; during this process, the contact member 733 rotates (because the pressure from the lower pressure plate causes the material to dent, the lower pressure plate is located in the dented area, and the contact member 733 is located at the edge of the dented area, and the edge of the dented area is inclined, thus causing the contact member 733 to rotate into an inclined state), which will push the movable block 735 upward, pull the pull rope 7323, and cause the limiting block 7321 to move out of the limiting groove 73 8. The inner cavity is removed, releasing the restriction on the guide block 732; under the thrust of the elastic element 737, the guide block 732 will move along with the mounting block 731 and the contact member 733 to both sides of the pressure head 73 (causing the contact member 733 to move towards the edge of the processed material; because the edge of the hollow material has greater strength, the probability of deformation when fixing the processed material again is low); during the upward movement of the movable block 735, the touch switch 7312 will be pressed, energizing the telescopic mechanism 713, which will move the lower pressure plate upward as a whole, ensuring safety. The mounting block 731 and contact member 733 can move to both sides of the pressure head 73; when the lower pressure plate moves upward, it will cause the recessed area of ​​the processed material to disappear, and at the same time, the contact member 733 will tend to be parallel, causing the movable block 735 to move downward and reset, and not to contact the touch switch 7312, so that the telescopic mechanism 713 is de-energized and stops working; it will also cause the tension applied by the pull rope 7323 to the limit block 7321 to disappear, and under the action of the spring member, one end of the limit block 7321 will move to the outside of the mounting groove 7322, and move with the guide block 732, so that the limit block 7321 moves to the outside of the mounting groove 7322, and moves ... When 321 is aligned with the limiting groove 738, the limiting block 7321 will be inserted into the limiting groove 738, further restricting the guide block 732 so that it will not move; when the processed material is fixed and does not dent, the guide block 732, mounting block 731 and contact member 733 and other components will not work; and after the processed material is processed, the contact member 733 and mounting block 731 and other components that have moved need to be reset, and the telescopic mechanism 713 needs to be adjusted to ensure that the movable rod 712 can still move upward when the contact member 733 and other components are working.

[0033] In this embodiment, as a further optimization, please refer to section 2. Figure 3 and Figure 4The limiting components include a threaded rod 41 mounted on the base 2, a nut 42 sleeved on the outer wall of the threaded rod 41, and a pressure block 43 mounted on the bottom of the nut 42. The end of the threaded rod 41 away from the base 2 passes through the flipping pressure plate 3. An opening 5 is provided at the connection between the flipping pressure plate 3 and the threaded rod 41. The bottom of the pressure block 43 is in contact with the top wall of the flipping pressure plate 3 (to limit the flipping pressure plate 3). A handle 9 is hinged to the nut 42. By holding the handle 9 and rotating it around the center of the nut 42, the nut 42 rotates with the pressure block 43. The pressure block 43 is rotated to a position directly opposite the opening 5 so that the pressure block 43 does not contact the flipping pressure plate 3. This ensures that when the flipping pressure plate 3 rotates, the nut 42 and the pressure block 43 can pass through the opening 5, and the handle 9 can also pass through the opening 5, ensuring that the flipping pressure plate 3 flips outward normally.

[0034] In this embodiment, as a further optimization, please refer to 1. Figure 2 and Figure 3 The base 2 is provided with an elastic support 6. The top of the elastic support 6 is attached to the bottom wall of the flipping pressure plate 3 to support the flipping pressure plate 3. When the pressure block 43 is released from the restriction of the flipping pressure plate 3, the elastic support 6 will push the flipping pressure plate 3 upward, making it easy to rotate the flipping pressure plate 3 outward. And when the flipping pressure plate 3 rotates inward (that is, when the pressing part 7 is moved above the processing material and the processing material needs to be fixed), the elastic support 6 can support the flipping pressure plate 3, so as to prevent the flipping pressure plate 3 from accidentally getting out of the operator's control during the inward flipping process, which would cause the equipment to vibrate greatly.

[0035] In this embodiment, as a further optimization, please refer to 1 and Figure 2 A limiting mechanism 8 is provided on the side wall of the base 2; wherein, the limiting mechanism 8 includes a lead screw 81, a side stop 82 and a rotating part 83. The lead screw 81 is screwed to the side wall of the base 2, the rotating part 83 is installed on the outer end of the lead screw 81, and the side stop 82 is installed on the inner end of the lead screw 81. By rotating the lead screw 81, the side stop 82 moves inward to fit against the side wall of the processing material, which is used to limit the processing material and ensure the stability of the clamping assembly in fixing the processing material.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
