[0036] In this embodiment, it should be noted that when the collecting component 14 needs to be replaced, the adjusting structure 17 can be driven to rotate by the external driving structure, so that the two clamping structures 15 move toward the middle to clamp, and then trigger the structure on the impact component 13, so that the impact component 13 releases the clamping restriction on the collecting component 14, so that the collecting component 14 can be taken out from the groove 8 and replaced, and then the support structure 16 is used to clamp the newly replaced collecting component 14 to ensure that the position is relatively stable, and combined with the subsequent rotation, the collecting component 14 is automatically clamped to the impact component 13 during the rotation process to complete the replacement.

[0038] In this embodiment, it should be noted that when replacing the collecting component 14, the electric telescopic rod 3 can be extended to allow the long rod 4 to push the slot 8 to expand, thereby allowing the impact component 13 to extend outward and push its end as close to the collecting component 14 as possible, thereby ensuring that the collecting component 14 can be connected to the impact component 13 under subsequent low-speed conditions, thereby ensuring the reliability of replacing the collecting component 14.

[0039] See also Figure 1-4 A dual-spindle turning and milling compound CNC machine tool includes a clamping structure 15, the number of the clamping structures 15 is two, and one is movably installed in the middle of the outer cylinder 5, and the other is movably installed near the side where the inner support assembly 18 is located, and the clamping structure 15 installed in the middle of the outer cylinder 5 is a fully enclosed setting, the bottom end of the inner support assembly 18 is plugged into the coolant recovery device of the machine tool, the middle guide pipe 10 communicates with the middle clamping structure 15 to divide the inner part of the outer cylinder 5 into two spaces, and one end of the liquid outlet 9 is connected to the liquid inlet end of the machine tool coolant supply device;

[0040] In this embodiment, it should be noted that the driving force generated by the rotating drive device connected to the processing clamping head 20 will be transmitted to the large gear 7 through the small gear 19, thereby driving the impact component 13 and the collecting component 14 inside the outer cylinder 5 to rotate, thereby realizing the rotational centrifugation of the coolant sucked up by the inner support component 18, so that the metal debris therein can be collected in large quantities in the collecting component 14 under the action of centrifugal force, thereby realizing rapid purification of the coolant, ensuring that the coolant can be quickly recycled, and greatly reducing the use cost of the device.

[0041] See also Figure 3-6 A dual-spindle turning and milling compound CNC machine tool includes a circular base rod assembly 6, the circular base rod assembly 6 includes a rod body 61, a square ring 62 is fixedly installed at one end of the rod body 61, a positioning rod 63 is fixedly installed at one end of the rod body 61, and a rod 64 is fixedly installed on the square ring 62;

[0042] In this embodiment, it should be noted that one end of the rod body 61 is inserted into the outer sleeve 12 and fixedly connected, the square ring 62 is adapted to one end of the inner support component 18, and the positioning rod 63 is inserted into one end of the inner support component 18 and movably arranged. In this way, the positioning of the positioning rod 63 can ensure the stability of the path of the inner support component 18 during the movement, thereby ensuring the stability of the deployment of the inner support component 18 when the collection component 14 needs to be replaced later, thereby ensuring the use effect of the entire structure.

[0043] See also Figure 3-9 A dual-spindle turning and milling compound CNC machine tool includes an impact assembly 13, the impact assembly 13 includes an outer plate 131, a leakage groove 132 is opened at the bottom of the outer plate 131, a first spring 133 is fixedly installed inside the outer plate 131, a slider 134 is movably installed inside the outer plate 131, a locking member 135 is movably embedded in the slider 134, and a second spring 136 is fixedly installed at one end of the locking member 135;

[0044] In this embodiment, it should be noted that the bottom end of the outer plate 131 passes through the inner support assembly 18 and is movably connected, the leakage groove 132 is located on both sides of the bottom end of the outer plate 131 and is opened through the inside of the outer plate 131, the bottom end of the slider 134 is fixedly connected to the top of the first spring 133, the top of the slider 134 is evenly provided with plug-in grooves, and the top of the locking piece 135 is L-shaped, and the bottom end of the collecting assembly 14 is plugged into the plug-in groove at the top of the slider 134. In this way, the first spring 133 will be stretched during the rotation process, so that the outer plate 131 carries the coolant to rotate and produce a centrifugal effect, so that the coolant carries the metal debris and flows into the inside of the collecting assembly 14, so that the metal debris remains in the collecting assembly 14, and the coolant flows out of it for recycling.

[0045] See also Figure 7-10 A dual-spindle milling compound CNC machine tool includes a collecting assembly 14, the collecting assembly 14 includes a collecting box 141, rollers 142 are movably embedded on both sides of the outside of the collecting box 141, an inner partition 143 is fixedly installed in the middle of the inner part of the collecting box 141, and a plug rod 144 is fixedly installed on the inner partition 143;

[0046] In this embodiment, it should be noted that the roller 142 can be supported and arranged together with the clamping structure 15 at one end inside the outer cylinder 5, the collection box 141 as a whole has magnetic attraction, the lower middle part of the inner partition 143 is spaced apart from the inside of the collection box 141, and the insertion rod 144 is inserted between the locking piece 135 and the insertion groove at the top of the outer plate 131, so that the centrifugal force generated by the rotation can be used to make the used coolant carry metal debris along the surface of the outer plate 131 toward the inside of the collection box 141. With the help of the magnetic attraction of the collection box 141, the metal debris can be separated, and the coolant flows into one side of the collection box 141. In this way, with the existence of the inner partition 143, the coolant needs to turn to flow inside the collection box 141 before it can flow out, and then the coolant overflows therein, which can ensure the separation effect of metal debris and also realize the rapid and effective purification and reuse of the coolant.

[0047] See also Figure 1-6A dual-spindle turning and milling compound CNC machine tool includes an inner support assembly 18, the inner support assembly 18 includes a square plate 181, a connecting rod 182 is movably mounted on the square plate 181, a base block 183 is movably mounted on one end of the connecting rod 182, a support rod 184 is fixedly mounted on one end of the connecting rod 182, and a top block 185 is fixedly mounted on the end of the support rod 184;

[0048] In this embodiment, it should be noted that a square groove is provided on one end of the square plate 181 located on the square ring 62, and the square groove is provided inside the long rod 4. The two ends of the connecting rod 182 are respectively connected by hinges, the base block 183 is movably sleeved on 64, and the top block 185 is arranged inside the outer plate 131. In this way, when the collecting component 14 needs to be replaced, the electric telescopic rod 3 can be extended to push the long rod 4 to move, so that the connecting rod 182 can slide the base block 183 along 64, and then the top block 185 pushes the slider 134 to move out, thereby ensuring that the end of the slider 134 can smoothly contact the plug-in collecting component 14 during the rotation process, thereby ensuring the reliability of replacing the collecting component 14.

[0049] Working principle: the rotary drive device drives the processing clamping head 20 to rotate, the processing clamping head 20 drives the small gear 19 to rotate, the small gear 19 drives the large gear 7 to rotate, the large gear 7 drives the circular base rod assembly 6 to rotate, the circular base rod assembly 6 drives the inner tube 11 to rotate, and then drives the impact assembly 13 and the collecting assembly 14 to rotate. During the rotation, suction is generated inside the outer cylinder 5, so that the inner support assembly 18 sucks the used coolant at the bottom into it, and the coolant will flow to the inside of the collecting box 141 along the surface of the outer plate 131 under the action of centrifugal force, and the metal debris will stay in the collecting box 141. When the coolant in the collecting box 141 is excessive, the coolant flows out by overflow, and then is guided to the other side of the inner part of the outer cylinder 5 through the intermediate guide pipe 10, and then overflows and is discharged from the top after it is filled, and then is sucked into the original machine tool coolant pumping device for circulation. The ring is used. When the collecting component 14 needs to be replaced, the bottom plate 1 is moved up and down to allow the small gear 19 and the large gear 7 to alternately disengage and mesh. The adjusting structure 17 is driven to rotate by the external rotary drive structure, so that the clamping structure 15 is contracted toward the middle to clamp the two sides of the collecting component 14. At the same time, the locking piece 135 is also pushed to move and open the plug-in slot at the top of the slider 134. In this way, after the impact component 13 continues to rotate, the collecting component 14 will be disengaged, and then the collecting component 14 will be taken out from the through groove 8, and replaced with a new collecting component 14. When the clamping structure 15 gathers and clamps toward the middle, the supporting structure 16 will support the bottom of the roller 142. Therefore, after the collecting component 14 is placed in, the bottom plate 1 continues to move up and down, allowing the circular base rod component 6 to intermittently receive the rotational driving force, so that the impact component 13 is rotated to clamp the collecting component 14 to complete the replacement of the collecting component 14.
