When the five-axis rotary table body 2 is started, the connecting plate 23 drives the chassis 3 to rotate, and the chassis 3 drives the positioning plate 4 to rotate. The positioning plate 4 and the assembly plate 6 are fixedly connected by the reinforcing rib 5, so the assembly plate 6 rotates accordingly. Meanwhile, the pressure plate 81 of the corner cylinder 8 fixes the workpiece on the workpiece fixing plate 7. At the same time, the workpiece can move with the five-axis rotary table body 2, has multiple degrees of rotational freedom, and can process multiple positions of the workpiece. When processing certain positions, it is not necessary to disassemble and adjust the position before processing. It is suitable for more application scenarios and has high processing efficiency.

[0034] In one embodiment of this utility model, an assembly hole 61 is provided on one side of the assembly plate 6, and an assembly groove 62 is provided on the other side of the assembly plate 6. The corner cylinder 8 is fixedly installed in the assembly hole 61, and the workpiece fixing plate 7 is fixedly installed on the assembly groove 62 by bolts. The corner cylinder 8 is detachably installed in the assembly hole 61, and the position of the corner cylinder 8 can be moved up and down to adjust the extension and retraction height of the pressure plate 81 so as to better press the workpiece.

[0035] Furthermore, the assembly slot 62 is provided with a through hole 621 and a notch 622 for easy placement and removal of the workpiece fixing plate 7. The workpiece fixing plate 7 is placed and removed from the notch 622. The through hole 621 is for the purpose of fixing large products. The parts that do not need to be processed pass through the through hole 621, while the parts that need to be processed pass through the workpiece fixing plate 7 and are fixed by the pressure plate 81.

[0036] Furthermore, the workpiece fixing plate 7 is symmetrically provided with six first assembly holes 71, and the assembly groove 62 is symmetrically provided with eight second assembly holes 623. The first assembly holes 71 and the second assembly holes 623 are fixedly connected by bolts, with one first assembly hole 71 corresponding to one second assembly hole 623, so that the workpiece fixing plate 7 can be adjusted and fixed in position within the assembly groove 62. The spacing between each first assembly hole 71 is the same, and the spacing between each second assembly hole 623 is also the same, which facilitates fine adjustment of the position of the workpiece fixing plate 7 and facilitates processing.

[0037] In one embodiment of this utility model, the assembly plate 6 is provided with a plurality of positioning holes 63 at one end near the positioning disk 4, and a positioning post is fixedly installed in the positioning hole 63. The positioning disk 4 is provided with a plurality of third assembly holes 41, and the third assembly holes 41 are connected to the positioning holes 63 through the positioning post. The chassis 3 is provided with a plurality of chassis assembly holes 31, and the chassis assembly holes 31 are assembled and connected with the remaining third assembly holes 41, so that the chassis 3 drives the positioning disk 4 to rotate. The number of third assembly holes 41 on the positioning disk 4 is 13, the number of chassis assembly holes 31 is 8, and the number of positioning holes 63 is 3.

[0038] In one embodiment of this utility model, the reinforcing rib 5 is provided with a fourth assembly hole 51 that cooperates with and is fixed to the assembly plate 6 and a fifth assembly hole 52 that cooperates with and is fixed to the positioning plate 4. An assembly post is provided in the fifth assembly hole 52 and is inserted into the third assembly hole 41. At the same time, the fourth assembly hole 51 is fixedly connected to the assembly plate 6 by bolts, so that the positioning plate 4 drives the assembly plate 6 to rotate, allowing the workpiece to be processed in more positions.

[0039] In one embodiment of this utility model, the workpiece fixing plate 7 has a locking hole 72 in the middle for locking the workpiece. The locking hole 72 is an irregular hole-shaped structure, and the width at both ends of the locking hole 72 is smaller than the width in the middle. It is used to lock workpieces of a specific shape. The workpiece fixing plate 7 can be replaced according to the shape of the workpiece and can be applied to fixing various workpieces without the need for overall replacement, thus saving development costs.

[0040] In one embodiment of this utility model, a rubber component 82 is fixedly installed at the bottom of the pressure plate 81. The rubber component 82 is fixed to the bottom of the pressure plate 81 by bolts. When the pressure plate 81 presses down to clamp the workpiece, the rubber component 82 can prevent the workpiece from being crushed and play a buffering and protective role, while not affecting the clamping force.

[0041] When it is necessary to release the workpiece, the telescopic rotating end of the corner cylinder 8 extends upward and then rotates to one side, at which point the workpiece can be removed; if it is necessary to clamp the workpiece, place the workpiece, start the corner cylinder 8, its telescopic rotating end rotates to above the workpiece, and then retracts and presses down to clamp the workpiece, thereby fixing the workpiece.

[0042] In one embodiment of this utility model, the width of the end of the assembly plate 6 near the positioning disk 4 is smaller than the width of the end of the assembly plate 6 away from the positioning disk 4, so that the position of the workpiece fixing plate 7 is larger, which can be used to fix workpieces of different sizes and has a wide range of applications.

[0043] In one embodiment of this utility model, a base 10 is provided at the bottom of the base plate 1, and three T-shaped groove tracks 20 are provided on the base 10. Several fixing bolts 11 are fixedly provided on the base plate 1. One end of the fixing bolt 11 passes through the base plate 1 and is inserted into the T-shaped groove track 20, so that the base plate 1 can move back and forth along the length direction of the T-shaped groove track 20. When working with the cutting tool, the workpiece does not need to be disassembled to adjust the position, and the processing efficiency is high.
