[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0019] like Figs. 1 to 3 As shown, a five-axis machining center worktable for fixing aviation metal processing parts includes a worktable body 1, and the worktable body 1 is made of aluminum alloy. This arrangement makes the worktable body 1 less prone to corrosion, has better support, and increases service life. The surface of the worktable body 1 is provided with a plurality of first pin holes 12, wherein the interior of the first pin hole 12 is detachably installed with a positioning pin. For the aviation parts to be processed, it itself has a hole position for fixing, and this hole position can be aligned with the first pin hole 12. During the installation process, it is necessary to align the hole position with the first pin hole 12, and then insert the positioning pin into the interior. The inserted positioning pin is very important in the machine tool processing process. Especially for five-axis machine tools, locating pins can be used to limit the degrees of freedom of the workpiece to be processed, so that it maintains a fixed position in the mechanical system. It is a very reliable positioning element that can greatly improve the accuracy and stability of mechanical equipment. Since the locating pins are fixed on the tooling, they will not be affected by factors such as vibration and temperature changes, so their stability is very good. Locating pins can also help to quickly align the workpiece, simplify the assembly process, improve work efficiency, and facilitate disassembly. After positioning is completed, if the workpiece cannot move within a certain range, it means that accurate positioning has been achieved. If the positioning fails, such as random shaking or inability to assemble correctly, it means that the positioning is unsuccessful, which may affect the normal operation of the machine tool equipment.

[0020] In this embodiment, the shape of the worktable body 1 is circular, and the corners of the worktable body 1 are chamfered. This setting is to prevent workers from cutting their bodies when installing or fixing / disassembling workpieces and installing, disassembling, and carrying the worktable. The surface of the worktable body 1 is also provided with a plurality of first through holes 11, and the interior of the first through holes 11 is provided with a plurality of removable wire braces for auxiliary fastening of the workpiece. There is an interference fit between the wire braces and the first through holes 11, and the interior of the wire braces is provided with a threaded inner hole. After such a setting, since some workpieces to be processed themselves have threaded holes, or aviation workpieces that have been processed by machine tools have threaded holes, then their threaded holes can be aligned with the first circular holes 13, and the fit between each threaded hole and the wire brace can be fixed by external bolts. Moreover, since the wire braces are removable, they can be taken out and replaced with new ones after being damaged. Such a design makes the entire tooling have better adaptability and versatility.

[0021] In this embodiment, the surface of the worktable body 1 is further provided with a plurality of table fixing holes 13, and the external bolts pass through the table fixing holes 13 to be connected to the worktable on the machine tool. The table fixing holes 13 are countersunk holes. This arrangement is to ensure that the end of the entire bolt is sunken into the interior of the worktable body 1 after fixation, thereby ensuring the flatness of the surface of the worktable body 1. The plurality of first through holes 11 and first pin holes 12 on the surface of the worktable body 1 are staggered to form a cross shape 14. Since the length or width of this cross shape 14 is spread over the entire surface of the worktable body 1, this arrangement allows the two ends of some oddly shaped workpieces to be processed to be aligned with the hole positions in the cross shape 14 area. The remaining end of the workpiece is then aligned with the first pin hole 12 or the first through hole 11 on the surface of the workbench body 1. At this time, a triangular area is formed for fixation, thereby achieving the adaptability and versatility of the entire tooling. The diameter of the table fixing hole 13 is larger than the diameters of the first through hole 11 and the first pin hole 12. This setting is to ensure that the workbench body 1 is more stable and will not shake when installed on the airport workbench. The number of the first through holes 11 is greater than the number of the first pin holes 12, and the number of the first pin holes 12 is greater than the number of the table fixing holes 13. This setting is to ensure that the entire tooling has more fixing hole positions, so that users can quickly select the appropriate hole position according to their needs when fixing.

[0022] Working principle and usage of this utility model:

[0023] First, the external bolts are passed through the table fixing holes 13 to connect to the workbench of the five-axis machine tool. The table fixing holes 13 are countersunk holes to ensure that the ends of the bolts are sunken into the interior of the workbench body 1 after fixing, ensuring the flatness of the surface of the workbench body 1. Then, the aviation parts to be processed are installed. If there are holes for fixing, these holes can be aligned with the first pin holes 12. During the installation process, the holes need to be aligned [2] In the first pin hole 12, the locating pin is then inserted into the inside. The inserted locating pin is very important in the machine tool processing process, especially for five-axis machine tools. The locating pin can be used to limit the degree of freedom of the workpiece to be processed, so that it maintains a fixed position in the mechanical system. If the aviation workpiece to be processed itself has a threaded hole, or the aviation workpiece that has been processed by the machine tool has a threaded hole, then its threaded hole can be aligned with the first circular hole 13, and then the external bolts are used to fix the fit between each threaded hole and the wire brace. Moreover, since the wire brace is removable, it can be taken out and replaced with a new one after being damaged. This design makes the entire tooling have better adaptability and versatility. For some oddly shaped workpieces to be processed, the two ends can be aligned with the hole position in the cross-shaped 14 area, and the remaining end of the workpiece to be processed is aligned with the first pin hole 12 or the first through hole 11 on the surface of the worktable body 1. At this time, a triangular area is fixed, thereby realizing the adaptability and versatility of the entire tooling.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
