Description

Technical Field

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. They are generally classified into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools. Modern mechanical manufacturing employs many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, and extrusion. However, parts requiring high precision and fine surface roughness generally require final machining on a machine tool using cutting methods.

The two spindle boxes are respectively disposed at the upper ends of the machine body. A positive spindle and a secondary spindle are respectively disposed inside the two spindle boxes. An X1 drive shaft is disposed on the upper side between the positive spindle and the secondary spindle. A Y drive shaft is disposed on the side of the X1 drive shaft near the machine body. The positive servo power turret is disposed in front of the Y drive shaft. An X2 drive shaft is disposed on the lower side between the positive spindle and the secondary spindle. A Z1 drive shaft is disposed on the side of the positive spindle near the secondary spindle. A Z2 drive shaft is disposed on the side of the X2 drive shaft near the secondary spindle.

[0004] When using existing equipment, the workpiece can be accurately transferred between the machining table and the movable machining mechanism. However, due to the lack of an adaptive clamping mechanism, the workpiece is prone to loosening or deformation, which requires stopping the machine for adjustment. This fails to give full play to the advantages of dual-spindle dual-turret composite machining and reduces the machining speed, making it difficult to adapt to the needs of mass production. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dual-spindle, dual-turret CNC milling and turning machine for intelligent manufacturing, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A dual-spindle dual-turret CNC milling and turning composite machine for intelligent manufacturing, comprising a base, a machining table fixedly connected to the top of the base, a second tool holder fixedly connected to the top of the base, a first moving device fixedly connected to the top of the base, a first tool holder fixedly connected to the movable end of the first moving device, a second moving device fixedly connected to the top of the base, and a machining mechanism rotatably connected to the movable end of the second moving device; The processing mechanism includes: A rotating shaft is provided, the outer wall of which is rotatably connected to the frame at the top of the second moving device via a bearing.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Example 1: See Figures 1-8The present invention provides a technical solution: a dual-spindle dual-turret CNC turning and milling composite machine for intelligent manufacturing, including a base 1, a processing table 2 fixedly connected to the top of the base 1, a second tool holder 3 fixedly connected to the top of the base 1, a first moving device 4 fixedly connected to the top of the base 1, a first tool holder 5 fixedly connected to the movable end of the first moving device 4, and a fixing component 71 provided so that the workpiece can be quickly and stably changed between the processing table 2 and the processing mechanism 7; a second moving device 6 fixedly connected to the top of the base 1, and a processing mechanism 7 rotatably connected to the movable end of the second moving device 6. The processing mechanism 7 includes: a rotating shaft 701, the outer wall of which is rotatably connected to the frame at the top of the second moving device 6 via a bearing; a fixing assembly 71 is fixedly connected to the inner wall of the rotating shaft 701; a drive roller 702 is fixedly connected to the right side of the rotating shaft 701; the outer wall of the drive roller 702 is rotatably connected to the output end of the moving end at the top of the second moving device 6 via a belt; a push rod 703 is fixedly connected to the top of the moving end of the second moving device 6; a first connecting rod 704 is fixedly connected to the output end of the push rod 703; the first connecting rod 704 passes through the drive roller 702 and extends into the interior of the fixing assembly 71; wherein the push rod 703 can drive the first connecting rod 704 to move, and the movement of the first connecting rod 704 can change the state inside the fixing assembly 71.

[0026] The fixing component 71 includes a first outer shell 711, the outer wall of which is fixedly connected to the rotating shaft 701. A second outer shell 712 is fixedly connected to the left side of the first outer shell 711. A first limiting plate 715 is fixedly connected inside the second outer shell 712. A track 716 is fixedly connected to the inner wall of the first outer shell 711. An auxiliary component 74 is movably connected to the inner wall of the track 716. A placement component 73 is movably connected to the inner wall of the first limiting plate 715. The movement of the first connecting rod 704 can change the state of the auxiliary component 74. An arc-shaped block 713 is fixedly connected to the inner wall of the second outer shell 712. An inclined groove 714 is provided on the outer wall of the arc-shaped block 713. A clamping component 72 is movably connected to the inner wall of the inclined groove 714. The movement of the placement component 73 can change the state of the clamping component 72 through the inclined groove 714.

[0027] The clamping assembly 72 includes an annular plate 721. A first connecting plate 722 is fixedly connected to the outer wall of the annular plate 721. A first force-bearing column 723 is fixedly connected to the end of the first connecting plate 722 away from the annular plate 721. The outer wall of the first force-bearing column 723 is movably connected to an inclined groove 714. A second connecting rod 724 is fixedly connected to the inner wall of the annular plate 721. A slider 725 is fixedly connected to the outer wall of the second connecting rod 724. The inclined groove 714 can change the height of the annular plate 721 through the first force-bearing column 723. The inner side of the annular plate 721 may even have a fixed... The fixed plate 726 has a groove 727 on its outer wall. The inner wall of the groove 727 is movably connected to the second connecting rod 724. A sliding column 728 is fixedly connected to the inner wall of the fixed plate 726. A first spring 729 is sleeved on the outer wall of the sliding column 728. The bottom of the first spring 729 is fixedly connected to the fixed plate 726, and the top of the first spring 729 is fixedly connected to the slider 725. The change in height of the annular plate 721 can adjust the pressure of the fixed plate 726 on the inner side. When the workpiece needs to be clamped, as the workpiece enters the fixed assembly 71... The placement component 73 will be pushed to move rearward along its movement path; during this process, the placement component 73 will drive the clamping component 72 to move rearward synchronously. Since the inclined groove 714 is designed with a preset inclined trajectory, when the clamping component 72 moves, its first force-bearing column 723 will slide along the inclined trajectory of the inclined groove 714 and simultaneously change its height. Because the first force-bearing column 723 is fixedly connected to the first connecting plate 722 and the annular plate 721, the height of the first force-bearing column 723 will drive the annular plate 721 to change its height synchronously; at this time, the annular plate 721... The second connecting rod 724, fixed to the inner wall of the ring plate 721, moves synchronously with the position change of the ring plate 721. The slider 725, fixed to the outer wall of the second connecting rod 724, slides along the preset guide trajectory of the slide groove 727 on the outer wall of the fixed plate 726. During the sliding process, the slider 725 will compress the first spring 729 sleeved on the outer wall of the sliding column 728, so that the first spring 729 forms an elastic thrust. This elastic thrust will act in the opposite direction on the fixed plate 726, pushing the fixed plate 726 to move closer to the workpiece, and finally achieving stable clamping and fixing of the workpiece.

[0028] Example 2: Please refer to Figures 9-12Based on Embodiment 1, the present invention provides the following technical solution: To ensure that the locked state of the device does not easily change, a placement component 73 and an auxiliary component 74 are provided. The placement component 73 includes a hollow column 731, the outer wall of which is movably connected to a first limiting plate 715, a second limiting plate 732 fixedly connected to the outer wall of the hollow column 731, the inner wall of the second limiting plate 732 movably connected to a fixing plate 726, a triangular prism 733 fixedly connected to the right side of the hollow column 731, a locking hole 734 provided on the outer wall of the triangular prism 733, a connecting column 735 fixedly connected to the end of the triangular prism 733 away from the hollow column 731, and a circular plate 736 fixedly connected to the end of the connecting column 735 away from the triangular prism 733. When the workpiece is being processed by the processing table 2 and the processing mechanism 7, the workpiece to be processed is first pushed into the hollow column 73 of the placement component 73. Inside 31, the initial bearing and positioning of the workpiece are completed. As the workpiece is continuously pushed in, it will push the placement component 73 to move backward, which will then drive the clamping component 72 to move, so that the fixing plate 726 of the clamping component 72 gradually moves towards the workpiece along the preset trajectory, and finally achieves stable clamping and fixing of the workpiece. During this process, the continuous pushing of the workpiece will also drive the hollow column 731 and the second limiting plate 732 to move backward along the trajectory of the first limiting plate 715 until the hollow column 731 drives the entire placement component 73 to reach the preset processing position. At this time, the locking component of the auxiliary component 74 is embedded in the locking hole 734 on the outer wall of the triangular column 733. By locking the position of the triangular column 733, the overall position of the placement component 73 is indirectly fixed, effectively avoiding displacement of the placement component 73 during processing, thereby ensuring that the workpiece processing accuracy is not affected by the movement of the component.

[0029] The auxiliary component 74 includes a connecting ring 741, the outer wall of which is fixedly connected to the first housing 711. An elastic component 742 is fixedly connected to the inner wall of the connecting ring 741. A connecting block 743 is fixedly connected to the end of the elastic component 742 away from the connecting ring 741. A locking pin 745 is fixedly connected to the end of the connecting block 743 away from the connecting ring 741. A second connecting plate 744 is fixedly connected to the right side of the connecting block 743. A right-angle rod 746 is rotatably connected to the end of the second connecting plate 744 away from the connecting block 743 via a bearing. The locking pin 745 can be inserted into the locking hole 734 by the elastic force of the elastic component 742, thereby locking the placement component 73. At the position, a first sliding ring 747 is movably connected to the inner wall of track 716. A third connecting plate 748 is fixedly connected to the inner wall of the first sliding ring 747. A second sliding ring 7411 is fixedly connected to the end of the third connecting plate 748 away from the first sliding ring 747. A connector 7412 is fixedly connected to the outer wall of the second sliding ring 7411. The outer wall of the connector 7412 is rotatably connected to a right-angle rod 746 via a bearing. The inner wall of the second sliding ring 7411 is movably connected to a connecting post 735. A second spring 7413 is sleeved on the outer wall of the connecting post 735. One end of the second spring 7413 is fixedly connected to a circular plate 736. The second spring 7413 is located away from the circular plate 736. One end of 6 is fixedly connected to the second sliding ring 7411, and a connecting frame 749 is fixedly connected to the right side of the third connecting plate 748. The end of the connecting frame 749 away from the third connecting plate 748 is fixedly connected to the second force-bearing column 7410. The movement of the first connecting rod 704 can push the movement of the second force-bearing column 7410. When it is necessary to lock the position of the placement component 73, the elastic component 742 fixed to the inner wall of the connecting ring 741 is initially in a compressed state, which can apply a continuous elastic force to the inward side, giving the connecting block 743 a tendency to move in the direction of the placement component 73. When the placement component 73 moves to the preset processing position with the workpiece, the outer wall of the triangular prism 733 The locking hole 734 is aligned with the locking post 745. At this time, the elastic force of the elastic component 742 continuously pushes the connecting block 743, causing the locking post 745 to be embedded in the locking hole 734, restricting the axial movement of the placement component 73, and realizing the position locking of the placement component 73. This prevents the placement component 73 from shifting during processing. During the movement of the connecting block 743, the second connecting plate 744 on its right side drives the right-angle rod 746 to move synchronously through the bearing. The right-angle rod 746 pushes the second sliding ring 7411 to slide along the connecting post 735 and the track 716 until the locking post 745 is embedded in the locking hole 734. Then, the second sliding ring 7411 maintains a stable position with the right-angle rod 746. When the completed workpiece needs to be pushed out, the push rod 703 drives the first connecting rod 704 to move towards the auxiliary component 74; the first connecting rod 704 directly acts on the second force-bearing column 7410, and drives the second force-bearing column 7410, the connecting frame 749, the third connecting plate 748 and the second sliding ring 7411 to move synchronously through the thrust. During this process, the second sliding ring 7411 slides along the connecting post 735, simultaneously stretching the second spring 7413 on the outer wall of the connecting post 735. At the same time, the connecting head 7412 on the outer wall of the second sliding ring 7411 drives the right-angle rod 746 to rotate around the connecting head 7412. The right-angle rod 746 pushes the connecting block 743 through the second connecting plate 744, causing the connecting block 743 to overcome the elastic force of the elastic component 742 and move towards the connecting ring 741. This causes the locking post 745 to disengage from the locking hole 734, releasing the position lock on the placement component 73. After the locking post 745 disengages from the locking hole 734, the compressed second spring 7413 releases its elastic potential energy, pushing the placement component 73 to reset along the preset trajectory. During the reset process of the placement component 73, the clamping component 72 will be linked to release the clamping of the workpiece. Finally, under the pushing force of the placement component 73, the workpiece is pushed out of the processing mechanism 7, completing the entire unloading process and preparing for the next workpiece clamping and locking.
