[0002] The CNC machine tool transmits the compiled processing program to the CNC system, which controls the action sequence, movement amount and feed speed of the lathe feed moving parts through the X, Z (or other) coordinate axis servo motors. Combined with the spindle speed and direction, it can process various shapes of shaft or disk-type rotating parts.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides a dual-servo turret CNC lathe, comprising a body 1; a spindle unit 2, comprising a headstock 21 disposed on the body 1, a rotary cylinder 22 disposed on one side of the headstock 21, and a spindle 23 disposed at the output end of the headstock 21;

[0037] The tail fixing unit 3 includes a linear component 31 disposed on the top of the vehicle body 1 and a tail top mechanism 32 disposed on the top of the linear component 31;

[0038] The turning unit 4 includes a CNC slide 41 provided on both sides of the linear assembly 31 and a servo turret 42 provided at the moving end of the CNC slide 41;

[0039] The shielding unit 5 includes a fixing base 51 provided on both sides of the linear assembly 31, a shielding belt 52 slidably connected to the upper surface of the fixing base 51, a connecting plate 53 provided at one end of the shielding belt 52, and a winding assembly 54 provided at the other end of the shielding belt 52;

[0040] The connecting plate 53 is fixedly connected to the moving end of the linear component 31 .

[0041] It should be noted that the upper surface of the vehicle body 1 is fixedly connected to a headstock 21, a rotary oil cylinder 22 is fixedly connected to one side of the headstock 21, and a main shaft 23 is fixedly connected to the other side;

[0042] The upper surface of the vehicle body 1 is further fixedly connected to a linear assembly 31, which is preferably composed of a linear guide rail, a ball screw, and a servo motor. A tail lift mechanism 32 is fixedly connected to the moving end of the linear assembly 31. The tail lift mechanism 32 and the main shaft 23 are located at the same height and on the same horizontal line.

[0043] The processing area is between the main spindle 23 and the tail lift mechanism 32. CNC slides 41 are provided on both sides of the processing area. The CNC slides 41 are fixedly mounted on the top of the vehicle body 1. The CNC slides 41 are composed of an X-axis moving assembly 411 and a Y-axis moving assembly 412 fixedly mounted on the moving end of the X-axis moving assembly 411. The X-axis moving assembly 411 and the Y-axis moving assembly 412 are preferably composed of linear guides, roller screws, and servo motors. A servo turret 42 is fixedly connected to the moving end of the Y-axis moving assembly 412.

[0044] The shielding unit 5 forms a shield on the top of the linear component 31, which can prevent metal chips dropped during the processing from entering the components of the linear component 31. The fixed seat 51 is wrapped around the outside of the linear component 31 and is fixedly connected to the vehicle body 1. A connecting plate 53 is fixedly connected to the movable end of the linear component 31, and a shielding belt 52 is fixedly connected to one side of the connecting plate 53. The winding component 54 is fixedly connected to one side of the fixed seat 51, and the other end of the shielding belt 52 is wound around the winding component 54.

[0045] When in use, the motor is connected to the main shaft 23 through a belt, the metal raw material is fixed on the main shaft 23, and then the tail end of the metal raw material is fixed by starting the linear component. By setting the linear component, it can meet the processing needs of metal raw materials of various lengths;

[0046] Start the equipment, and use the motor to drive the spindle 23 to rotate, thereby driving the metal raw material to rotate. The CNC slide 41 moves the servo turrets 42 to their respective processing areas through the X-axis moving component 411 and the Y-axis moving component. Then, the two servo turrets 42 advance toward the center of the metal raw material from both ends to process the outer surface of the metal raw material. After the outer surface processing is completed, the CNC slide 41 moves the two servo turrets 42 to the place where the groove needs to be opened for processing. Since the two servo turrets 42 are located on both sides of the metal material, there will be no interference when grooving, and the effect of opening two grooves at the same time is achieved.

[0047] When the linear component 31 moves and fixes the metal raw material, it will drive the connecting plate 53 to move, and the connecting plate 53 will pull the shielding belt 52 to shield the formed metal processing area. During processing, metal chips will fall on the shielding belt 52.

[0048] In summary, by adding a linear component 31 to the bottom of the original conventional tail top mechanism 32, it is possible to fix metal raw materials of different lengths, and add two CNC slides 41 to drive two servo turrets 42 to work to realize the processing of raw materials, thereby improving work efficiency. By driving the shielding belt 52 to move by the linear component 31, the formed processing area can be shielded to prevent metal chips from entering the linear component 31.

[0049] like Figure 4 As shown, as an optional embodiment: the winding assembly 54 includes a fixed shell 541 provided at one end of the fixed base 51, a coil spring 542 provided in the inner cavity of the fixed shell 541, and a rotating rod 543 provided in the fixed shell 541;

[0050] One end of the coil spring 542 is fixedly connected to the inner wall of the fixed shell 541 , and the other end of the coil spring 542 is fixedly connected to the rotating rod 543 . The shielding belt 52 passes through the fixing seat 51 and is wrapped around the outer wall of the rotating rod 543 .

[0051] It should be noted that one end of the fixed seat 51 is fixedly connected to a fixed shell 541, and the inner wall of the fixed shell 541 is rotatably connected to a rotating rod 543. A coil spring 542 is provided between the rotating rod 543 and the fixed shell 541, and the two ends of the coil spring 542 are respectively fixedly connected to the outer wall of the rotating rod 543 and the inner wall of the fixed shell 541. One end of the shielding belt 52 is fixedly connected to the outer wall of the rotating rod 543 and is wrapped around the rotating rod 543 as the rotating rod 543 rotates. The shielding belt 52 passes through the fixed seat 51.

[0052] When in use, the shielding belt 52 is pulled to move by the connecting plate 53, and the shielding belt 52 will drive the rotating rod 543 to rotate, and apply force to the coil spring 542. Under the elastic action of the coil spring 542, a reverse rotational force will be generated on the rotating rod 543, so that the shielding belt 52 is in a taut state, and the shielding belt 52 will shield the linear component 31.

[0053] like Figure 5 As an optional embodiment: the collection unit 6 includes a storage cover 61 disposed on the top of the fixed shell 541, a connecting pipe 62 disposed on one side of the storage cover 61, a solenoid valve 63 disposed on the connecting pipe 62, a connecting terminal 64 disposed at the rear end of the connecting pipe 62, a trigger assembly 65 disposed between the connecting plate 53 and the fixing base 51, and a filter disposed at the top of the connecting pipe 62;

[0054] The connection terminal 64 is connected to an external negative pressure device.

[0055] It should be noted that multiple sets of storage covers 61 are fixedly connected to the top of the fixed shell 541. The inner cavity of the storage cover 61 is connected to a connecting pipe 62, and the storage cover 61 faces the shielding belt 52. The storage cover 61 is located on both sides of the shielding belt 52 and does not affect the movement of the shielding belt 52. The thickness of the storage cover 61 is almost the same as the thickness of the shielding belt 52. A solenoid valve 63 is fixedly connected to the connecting pipe 62. A connecting terminal 64 is fixedly connected to the tail end of the connecting pipe 62. The connecting terminal 64 is connected to the external negative pressure equipment. A filter is provided at the top of the connecting pipe 62.

[0056] When in use, it is connected to an external negative pressure device through the connecting end 64. During the movement of the linear component 31, the corresponding solenoid valve 63 will be opened through the trigger component 65, and the storage cover 61 will generate suction through the external negative pressure device to suck the metal chips fallen from the surface of the shielding belt 52 into the storage cover 61. In addition, the only passage between the storage cover 61 and the connecting pipe 62 is provided with a filter to prevent metal chips from entering the connecting pipe 62. After the processing is completed, the negative pressure device is turned off and the metal chips in the storage cover 61 are cleaned up in a centralized manner.

[0057] In summary, by setting up multiple suction storage covers 61 to collect the fallen iron chips, it is possible to prevent the problem of inconvenience in collecting the metal chips on the surface of the shielding belt 52 after the processing is completed due to the obstruction of the shielding belt 52 around them.

[0058] like Figure 6 As shown in the figure, as an optional embodiment: the trigger assembly 65 includes a mounting plate 651 provided on the inner side of the fixing base 51, a paddle switch 652 provided on the upper surface of the mounting plate 651, and trigger members 653 provided on both sides of the connecting plate 53.

[0059] Specifically, preferably, the trigger member 653 includes a slide plate 6531 slidably arranged on the inner wall of the bottom of the connecting plate 53, a spring 6532 arranged between the top of the slide plate 6531 and the inner cavity of the connecting plate 53, and a limiting rod 6533 arranged in the inner cavity of the connecting plate 53;

[0060] The slide plate 6531 and the limiting rod 6533 are slidably connected.

[0061] It should be noted that a mounting plate 651 is fixedly connected to the inner side of the fixing seat 51, and a number of paddle switches 652 corresponding to the storage cover 61 are fixedly connected to the mounting plate 651. A slide plate 6531 is slidably connected to the bottom of the connecting plate 53, and a spring 6532 is arranged between the slide plate 6531 and the inner cavity of the connecting plate 53. A limiting rod 6533 is also fixedly connected to the inner cavity of the connecting plate 53, and the bottom end of the limiting rod 6533 is slidably connected to the inner cavity of the slide plate 6531.

[0062] During use, when the connecting plate 53 moves following the linear component 31, the slide 6531 will push the paddle of the paddle switch 652. After pushing the paddle to open or close the solenoid valve 63, the slide 6531 will slide along the upper surface of the paddle and shrink toward the inner cavity of the connecting plate 53 under the pushing action of the paddle surface until it passes through the paddle.

[0063] In summary, by pushing the paddle switch 652 through the connecting plate 53, and then sliding along the surface of the paddle, the solenoid valve 63 at the corresponding position is opened or closed, which can prevent the problem that all the solenoid valves 63 are opened and the suction force generated by the remaining storage covers 61 causes interference with the movement of metal chips and falls from the connecting plate 53 into the linear component 31.

[0064] like Figure 5 As shown, as an optional embodiment: one side of the connecting pipe 62 is connected to a branch pipe 621, and one end of the branch pipe 621 is arranged on the upper surface of the fixing seat 51;

[0065] The radius of the branch pipe 621 is smaller than the radius of the connecting pipe 62 .

[0066] During use, when the solenoid valve 63 is opened, both the branch pipe 621 and the connecting pipe 62 will generate suction. The top end of the branch pipe 621 is set on the inner wall of the fixed seat 51 and is located on the upper surface of the fixed seat 51, so that the upper surface of the fixed seat 51 generates suction, which can adsorb the shielding belt 52 and make the shielding belt 52 fit tightly with the fixed seat 51, and can prevent metal chips from entering the linear component 31 through the gap between the shielding belt 52 and the fixed seat 51. In addition, the radius of the branch pipe 621 is smaller than the radius of the connecting pipe 62, and the suction flowing through is smaller than the suction of the connecting pipe 62, which can reduce the impact on the storage cover 61.

[0067] like Figure 1As shown, as an optional embodiment, an arc-shaped baffle is fixedly connected to the outer side of the servo turret 42.

[0068] It should be noted that the arc-shaped baffle can shield the metal chips flying during the processing so that they fall onto the shielding belt 52 .

[0069] 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.
