[0026] The turning mechanism 3 includes: a motion component 31, which is installed on the fixed seat 100; a multi-mode turning component 32, which is driven by the motion component 31 to perform turning; and a dual-mode cooling component 33, which performs dual-mode cooling on the multi-mode turning component 32.

[0030] The driving component 34 includes: a rotary driving member b341, which is installed inside the connecting rod 321; a disk gear 342, which is installed at the output end of the rotary driving member b341; a moving rod 343, a plurality of moving rods 343 are slidably arranged on the rotary disk 322, and a rotary cutter 324 is installed at one end of the moving rod 343; a gear b344, which is installed at the other end of the moving rod 343; a sliding sleeve 345, which is sleeved outside the moving rod 343; a sliding rod 346, which is installed on the sliding sleeve 345; a rotating table 347, which is rotatably arranged inside the rotary disk 322, a chute 348 is opened inside the rotating table 347, and the sliding rod 346 slides inside the chute 348.

[0031] A square block (not shown in the figure) is installed on the sliding sleeve 345, and a square groove (not shown in the figure) is opened inside the rotary disk 322, so that the sliding sleeve 345 can slide inside the rotary disk 322 but cannot rotate. A clamping groove (not shown in the figure) is opened inside the sliding sleeve 345, and a clamping block (not shown in the figure) is installed on the moving rod 343. The moving rod 343 can rotate inside the sliding sleeve 345. The sliding of the sliding sleeve 345 along the rotary disk 322 drives the moving rod 343 to move synchronously.

[0033] In this embodiment, there are four groups of rotary cutters 324, and the sizes and materials of each group of rotary cutters 324 are different, which is convenient for turning workpieces of different materials. For example Figure 4 As shown, the rotary cutter 324 at position A is the working cutter. The sliding rod 346 corresponding to the rotary cutter 324 at this position slides into the second track 3482, causing the gear b344 corresponding to the rotary cutter 324 at position A to mesh with the disk gear 342. The rotary driving member b341 drives the disk gear 342 to rotate, which can drive the rotary cutter 324 at position A to rotate for turning. For the sliding rods 346 corresponding to the other three groups of rotary cutters 324, they slide into the first rail 3481. The gear b344 corresponding to the rotary cutter 324 disengages from the disk teeth 342. When it is necessary to switch to the remaining rotary cutters 324 for turning, the rotary drive member c332 drives the rotating table 347 to rotate, driving the sliding rod 346 corresponding to the rotary cutter 324 to slide into the second rail 3482. The gear b344 corresponding to the rotary cutter 324 meshes with the disk teeth 342, thereby switching different rotary cutters 324 for turning and realizing turning in multiple modes.

[0044] A plurality of clamping points (not shown in the figure) can be arranged on the driving shaft 414, and a plurality of clamping holes (not shown in the figure) are arranged on the sliding strip 4171. The clamping points are inserted into the clamping holes to facilitate the driving shaft 414 to drive the filtering part 417 to move.

[0045] As Figure 15 shown, a sealing airbag 400 is arranged in the clamping seat 413. When filtering is required, the sealing airbag 400 is inflated and expanded for sealing. When the filtering part 417 needs to be cleaned, the sealing airbag 400 discharges gas and contracts.

[0046] Working steps Step 1: Feeding and clamping process: The workpiece to be turned is installed on the rotary table 209 through bolts, and then the workpiece to be turned is clamped on the rotary table 209, which is convenient for subsequent turning processes; Step 2: Five-axis turning process: The rotary driving member b341 drives the disk teeth 342 to rotate. Since the disk teeth 342 are engaged with the gear b344 on the lower rotary tool 324, it drives the lower moving rod 343 and the rotary tool 324 to rotate. The moving frame 202 slides on the third guide rail 201 (first axis), the moving frame 204 slides on the fourth guide rail 203 (second axis), the rotary driving member d206 drives the turning table 207 to turn (third axis), the rotary driving member e208 drives the rotary table 209 to rotate (fourth axis), and the lifting plate 314 moves on the second guide rail 313 (fifth axis), realizing five-axis machining of the workpiece clamped on the rotary table 209 by the rotary tool 324. The machining degree of freedom is high and the machining degree is high, which is convenient for machining workpieces with some complex structures; Step 3. Process switching: Rotate four groups of cutting tools 324. Each group of cutting tools 324 has different sizes and materials, which is convenient for turning workpieces of different materials. For example, Figure 4 and Figure 5 as shown in the figure, the cutting tool 324 at position A is the working tool. The sliding rod 346 corresponding to the cutting tool 324 at this position slides into the second rail 3482, causing the gear b344 corresponding to the cutting tool 324 at position A to engage with the disk teeth 342. The rotation driving part b341 drives the disk teeth 342 to rotate, which can drive the cutting tool 324 at position A to rotate for turning; For the sliding rods 346 corresponding to the other three groups of cutting tools 324, they slide into the first rail 3481. The gear b344 corresponding to the cutting tool 324 is disengaged from the disk teeth 342. When it is necessary to switch to the other cutting tools 324 for turning, the rotation driving part c332 drives the rotating table 347 to rotate, driving the sliding rod 346 corresponding to the cutting tool 324 to slide into the second rail 3482, and the gear b344 corresponding to the cutting tool 324 engages with the disk teeth 342; Step 3. Water cooling process: The water pump pumps the water flow in the water tank through the liquid inlet pipe 336, the fourth ring groove 3331, the flow cavity a3471, the liquid inlet groove 3341, and the first ring groove 3431 into the cooling groove 3241, and then discharges it into the water tank through the second ring groove 3432, the liquid discharge groove 3342, the flow cavity b3472, the fifth ring groove 3332, and the liquid discharge pipe 337. The water flow enters the liquid inlet groove 3341 to cool the cutting tool 324 internally, avoiding the cutting tool 324 from overheating during turning and affecting its use; Step 4. Blowing air for cooling and chip removal process: The compressor sprays high-pressure gas from the air spray holes 3242 after passing through the air pipe 338, the sixth ring groove 3333, the flow cavity c3473, the air inlet groove 3343, and the third ring groove 3433. The spraying of high-pressure gas can cool the cutting tool 324, and at the same time, it can also blow away the chips generated during turning, enhancing the turning quality; Step 5. Lubrication and filtration process: The circulating pump 404 pumps the lubricating oil into the shielding box 401 to lubricate the meshing between the gear b344 and the disk teeth 342 in the shielding box 401, enhancing the transmission effect between the gear b344 and the disk teeth 342; The circulating pump 404 pumps the lubricating oil in the shielding box 401 into the filtering housing 412, and the filtering part 417 filters the lubricating oil; Step 6. Two-way outward expansion cleaning process: The rotary drive member f427 drives one of the drive shafts 414 to rotate, driving the filter part 417 to slide in the T-shaped groove 4131, and transferring the impurities on the filter part 417 into the collection box; the linear drive member a421 drives the connecting frame 415 to move outward, driving the arc-shaped plate 418 and the drive shaft 414 to pull the flexible filter net 4172 from both sides, and pulling the flexible filter net 4172 in the X direction; The linear drive member d428 drives the moving plate 424 to move backward, driving the other moving plate 424 to move in the opposite direction through the gear c426, and driving the two clamping blocks 425 to pull the flexible filter net 4172 from the other two sides, and pulling the flexible filter net 4172 in the Y direction; Pull the flexible filter net 4172 from both the X and Y directions to expand the filter holes of the flexible filter net 4172, so that the impurities stuck in the filter holes fall into the collection box.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
