Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a dual-spindle turning and milling compound machine tool. Background Art

[0002] Traditional CNC machine tools generally use a single spindle structure and a separate power head. They are single-channel controlled and can only achieve single-axis processing of a single machine tool. If you need to achieve simultaneous processing of different processes, you need to use a robot to grab the workpieces of adjacent processes to achieve the coordination of multiple machine tools and achieve the effect of simultaneous processing. Because traditional turning and milling machines have 6 axes, they can achieve simultaneous processing of 4 axes at most. And because traditional turning and milling generally use a single ordinary power head, their transmission power is small and the processing efficiency is slow. Summary of the invention

[0046] When in use, the workpiece is fixed on the two main shafts by driving the oil cylinder 18, and the first motor 11 is rotated to drive the first mounting plate 14 to reach the double-headed turret 26. When the double-headed turret 26 can contact the workpiece, the first mounting plate 14 has pushed the baffle 342 to push the rotating plate 36 to rotate to the highest point, and the wiping block 35 is made of flexible material and can produce a certain degree of deformation.

[0048] like Figures 1 to 7As shown, as an optional embodiment: the cooling unit 4 includes a pumping assembly 41 arranged on the fixing rod 31, a water tank 42 arranged at the water inlet end of the pumping assembly 41, a spray assembly 43 arranged on one side of the double-headed turret 26, a driving assembly 44 arranged on the top of the pumping assembly 41, and a transmission assembly 45 arranged between the driving assembly 44 and the pumping assembly 41;

[0049] The shower assembly 43 is connected to the output end of the pumping assembly 41 .

[0050] Specifically preferably, the pumping assembly 41 includes an inlet pipe 411 and an outlet pipe 412 arranged at the bottom end of the fixed rod 31, a one-way valve 413 arranged on the inner wall of the inlet pipe 411 and the outlet pipe 412, a piston plate 414 slidably arranged in the inner cavity of the fixed rod 31, a rack 415 arranged on the top of the piston plate 414, a second spring 416 arranged between the piston plate 414 and the fixed rod 31, a driven shaft 417 rotatably arranged on the inner wall of the fixed rod 31, and a half gear 418 arranged at one end of the driven shaft 417;

[0051] The half gear 418 is meshed with the rack 415 .

[0052] It should be noted that the bottom end of the fixed rod 31 is fixedly connected with an inlet pipe 411 and an outlet pipe 412, and the inner cavities of both are provided with a one-way valve 413, the inlet pipe 411 has only a single inward passage, and the outlet pipe 412 has only a single outward passage, and a piston plate 414 is slidably connected to the inner cavity of the fixed rod 31, and a rack 415 is fixedly connected to the top of the piston plate 414, and a second spring 416 is provided between the piston plate 414 and the fixed rod 31, and a driven shaft 417 is rotatably connected to the inner wall of the fixed rod 31, and a half gear 418 is fixedly connected to one end of the driven shaft 417, and the half gear 418 is meshed with the rack 415.

[0053] Specifically and preferably, the spray assembly 43 includes a mounting frame 431 disposed on one side of the double-head turret 26 , and a spray head 432 disposed on the mounting frame 431 .

[0054] The spray head 432 is directed toward the cutter head.

[0055] It should be noted that the mounting frame 431 is fixedly mounted on one side of the double-headed turret 26 and is located between the two tool heads, and the nozzle 432 is directed toward the tool heads, thereby achieving precise cooling of the tool heads.

[0056] Specifically preferably, the driving assembly 44 includes a fixed tube 441 disposed at the top of the fixed rod 31, a transmission rod 442 rotatably disposed on the axis of the fixed tube 441, a limiting tube 443 rotatably disposed at both ends of the fixed tube 441, a connecting tube 444 slidably disposed at one end of the limiting tube 443, and a third spring 445 disposed between the connecting tube 444 and the fixed tube 441;

[0057] Both ends of the transmission rod 442 are slidably plugged into the connecting pipe 444 .

[0058] It should be noted that a fixing tube 441 is fixedly connected to the top of the fixing rod 31, a transmission rod 442 is rotatably connected to the axis of the fixing tube 441, both ends of the fixing tube 441 are fixedly connected to limiting tubes 443, the inner cavity of the limiting tube 443 is slidably connected to a connecting tube 444, the connecting tube 444 is made of rubber material and has an anti-slip effect, a third spring 445 is arranged between the connecting tube 444 and the fixing tube 441, both ends of the transmission rod 442 and the connecting tube 444 are slidably plugged, and when the connecting tube 444 rotates, the transmission rod 442 is driven to rotate.

[0060] When in use, when the spindle approaches the double-head turret and enters the processing area, the connecting tube 444 will contact one end of the workpiece, and the workpiece will squeeze the connecting tube 444. Under the elastic force of the third spring 445, the connecting tube 444 will fit tightly with the workpiece, and the connecting tube 444 has high anti-slip properties. When processing, the rotation of the workpiece will drive the connecting tube 444 to rotate, and then drive the transmission rod 442 to rotate;

[0061] When the transmission rod 442 rotates, it drives the driven shaft 417 to rotate through the belt, and the driven shaft 417 drives the half gear 418 to rotate continuously. The half gear 418 lifts the rack 415, drives the piston plate 414 to move upward, and draws coolant or water through the water inlet pipe 411. Then, when the gearless part of the half gear 418 rotates to the rack 415, under the extrusion of the second spring 416, the piston plate 414 is pushed downward, and the water or coolant is discharged from the water outlet pipe 412 to the nozzle 432, and then accurately sprayed from the nozzle 432 on the cutter head, thereby cooling the cutter head. This can prevent the cutter head from continuing to be high in temperature and reducing its service life under long-term high-efficiency working conditions.

[0062] like Figures 1 to 7 As an optional embodiment: the top of the water tank 42 is fixedly connected with a collecting pipe 421, and the top of the collecting pipe 421 is connected to the inner cavity of the receiving plate 33. The water or coolant sprayed on the cutter head rests on the receiving plate 33, and then flows into the water tank 42 along the collecting pipe 421, thereby realizing the recovery of water or coolant.

[0063] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
