[0043] like Figure 1-2The figure shows an automatic feeding CNC machine tool for processing materials, which includes a machine base 1, a first spindle device 2, a second spindle device 3, and an X-axis movable platform 4. A processing platform 11 is provided on the machine base 1. The first spindle device 2 is disposed on the machine base 1 and is located above the processing platform 11. The first spindle device 2 has a hollow rotary fixture 23, and the axis direction of the first spindle device 2 is the X-axis direction. The X-axis movable platform 4 is disposed on the processing platform 11 and is located to one side of the first spindle device 2. The second spindle device 3 is disposed on the X-axis movable platform 4. The second spindle device 3 has a rotary fixture 33, and the axis direction of the second spindle device 3 is the X-axis direction.

[0044] In the present invention, a processing platform 11 is provided with a first spindle assembly 2 and a second spindle assembly 3. An X-axis movable platform 4 is disposed on one side of the first spindle assembly 2, and the second spindle assembly 3 is disposed on the X-axis movable platform 4. The first and second spindle assemblies 2 and 3 have the same axial direction, so that a rod-shaped material can be fed from the first spindle assembly 2. After the end of the rod-shaped material protrudes from the second spindle assembly 3, the hollow rotary fixture 23 clamps the rod-shaped material and processes the first end to form the first processed end. Thereafter, the X-axis movable platform 4 carries the second spindle assembly 3 and is placed over the first processed end. The rotary fixture 33 clamps the first processed end, the hollow rotary fixture 23 is released, and the X-axis movable platform 4 drives the second spindle assembly 3 away from the first spindle assembly 2. The rod-shaped material is processed to form the second processed end, thereby completing the processing of both ends of the product. The processed material is then removed, and the processing of the first end is repeated. In this way, the X-axis moving platform 4 drives the second spindle device 3 to move repeatedly, so that the second spindle device 3 repeatedly pulls the rod-shaped material to feed, thereby realizing automatic feeding of the rod-shaped material.

[0045] In some embodiments of the first spindle device 2, such as Figure 2 、 Figure 3 As shown, the first spindle assembly 2 includes a first spindle 21, a spindle housing 22, and the aforementioned hollow rotary fixture 23. The spindle housing 22 is mounted on the machining platform 11, and the first spindle 21 is mounted within the spindle housing 22. Both ends of the first spindle 21 protrude, and the hollow rotary fixture 23 is mounted at one end of the first spindle 21. The first spindle 21 is hollow, and rod-shaped materials extend into the first spindle 21. Under the traction of the second spindle assembly 3, the rod-shaped materials are repeatedly fed.

[0046] The corresponding second spindle assembly 3 includes a second spindle 31, a spindle base 32, and a rotary fixture 33. The spindle base 32 is mounted on the X-axis movable platform 4, the second spindle 31 is mounted on the spindle base 32, and the rotary fixture 33 is mounted on the second spindle 31. The second spindle 31 is a hollow spindle. Through the cooperation of the X-axis movable platform 4 and the rotary fixture 33, the rod-shaped material is pulled and fed during the reciprocating movement of the second spindle assembly 3.

[0047] The rotary fixture 33 may be hollow or solid. The rotary fixture 33 is disposed at the second spindle 31 , preferably at an end away from the first spindle device.

[0048] The hollow rotary clamps 23 and 33 may be rotary hydraulic cylinders or rotary air cylinders.

[0049] In addition, the automatic feeding CNC machine tool further includes two driving devices for driving the first spindle 21 and the second spindle 31 to rotate. The driving devices specifically include a transmission belt, a motor, etc.

[0050] In some embodiments of the X-axis moving platform 4, such as Figure 2 As shown, the X-axis movable platform 4 includes a first sliding assembly 41 and a first drive assembly 42. The second spindle device 3 is disposed on the first sliding assembly 41, and the second spindle device 3 is further connected to the first drive assembly 42. Specifically, the second spindle device 3 is disposed on the first sliding assembly 41 via the Y-axis movable platform 5, and is connected to the first drive assembly 42 via the Y-axis movable platform 5.

[0051] For the first drive assembly 42, the first drive assembly 42 includes a first bearing seat, a first motor seat, a first screw rod, a first nut, a first screw rod seat and a first motor. The first screw rod is arranged along the X-axis direction, and the first bearing seat and the first motor seat are arranged on the processing platform 11 and are respectively arranged at the two ends of the first screw rod. Specifically, the two ends of the first screw rod are respectively connected to the first bearing seat and the first motor seat for rotation, such as the first screw rod is connected to the first bearing seat and the first motor seat for rotation through a bearing. The first nut is arranged on the first screw rod, the first screw rod seat is arranged on the first nut, the first motor is arranged on the first motor seat, and the first motor is connected to the first screw rod to drive the first screw rod to rotate. The second spindle device 3 is connected to the first screw rod seat.

[0052] The second spindle assembly 3 slides with the machine base 1 via a first sliding assembly 41, with the sliding engagement direction being the X-axis. Simultaneously, in the first drive assembly 42, the first motor, first screw, first nut, and first screw base cooperate to enable the first screw base to move along the X-axis, thereby driving the second spindle assembly 3 to move along the X-axis, ultimately driving the rod-shaped material along the X-axis.

[0053] As shown in the figure, the first sliding assembly 41 includes a first guide rail arranged along the X-axis direction and a first slider disposed on the first guide rail. The second spindle device 3 is disposed on the first slider, specifically, the second spindle device 3 is disposed on the first slider via the Y-axis movable platform 5. There are two first sliding assemblies 41, and the two sets of first sliding assemblies 41 are located on either side of the first drive assembly 42. Specifically, the two first guide rails are located on either side of the first screw rod. Through the sliding cooperation between the first slider and the first guide rail, the second spindle device 3 is slidably disposed on the machine tool base 1.

[0054] In some embodiments of the processing platform 11, such as Figure 2 As shown, the top of the machining platform 11 is provided with an X-axis groove 111 extending along the axial direction. The first drive assembly 42 is disposed within the X-axis groove 111. Two sets of first sliding assemblies 41 are provided, one on each side of the X-axis groove 111. The X-axis groove 111 reduces the installation height of the first drive assembly 42, preventing assembly interference with the second spindle assembly 3 or the Y-axis movable platform 5, and improving overall assembly convenience.

[0055] In some embodiments of the automatic feeding processing CNC machine tool, the automatic feeding processing CNC machine tool further includes a Y-axis moving platform 5, specifically, as Figure 2 、 Figure 4 As shown, the Y-axis movable platform 5 includes an upper slide 51, a lower slide 52, a second sliding assembly 53, and a second drive assembly 54. The lower slide 52 is disposed on the X-axis movable platform 4, the second sliding assembly 53 and the second drive assembly 54 are disposed on the lower slide 52, and the upper slide 51 is disposed on the second sliding assembly 53 and connected to the second drive assembly 54. The second spindle device 3 is disposed on the upper slide 51.

[0056] The upper slide 51 is connected to the second spindle assembly 3, and the lower slide 52 is connected to the X-axis moving platform 4, specifically the first slider and the first screw seat. Thus, the lower slide 52 receives the motion state transmitted from the first screw seat, and the upper slide 51 outputs the motion state to the second spindle assembly 3, causing the second spindle assembly 3 to move along the X and Y axes.

[0057] For the second drive assembly 54, the second drive assembly 54 includes a second bearing seat, a second motor seat, a second screw rod, a second nut, a second screw rod seat and a second motor. The second screw rod is arranged on the lower slide 52 along the Y-axis direction, and the second bearing seat and the second motor seat are arranged on the lower slide 52 and are respectively arranged at the two ends of the second screw rod. Specifically, the two ends of the second screw rod are respectively connected to the second bearing seat and the second motor seat for rotation, such as the second screw rod is connected to the second bearing seat and the second motor seat for rotation through a bearing. The second nut is arranged on the second screw rod, the second screw rod seat is arranged on the second nut, the second motor is arranged on the second motor seat, and the second motor is connected to the second screw rod to drive the second screw rod to rotate. The upper slide 51 is connected to the second screw rod seat.

[0058] The second spindle assembly 3 slides with the lower slide plate 52 via a second sliding assembly 53, with the sliding engagement direction being the Y-axis. Simultaneously, in the second drive assembly 54, the second motor, second screw, second nut, and second screw seat cooperate to enable the second screw seat to move along the Y-axis, thereby driving the second spindle assembly 3 to move along the Y-axis. Ultimately, the second spindle assembly 3 moves along the Y-axis, aligning the second spindle assembly 3 with the first spindle assembly 2, particularly aligning the second spindle 31 with the first spindle 21.

[0059] The second sliding assembly 53 includes a second guide rail arranged along the Y-axis and a second slider mounted on the second guide rail. The upper slide 51 is mounted on the second slider. There are two second sliding assemblies 53, one on each side of the second drive assembly 54. Specifically, the two second guide rails are located on either side of the second lead screw. The sliding engagement of the second slider and the second guide rail allows the second spindle assembly 3 to slide on the Y-axis movable platform 5.

[0060] In some embodiments of the lower slide plate 52, as Figure 4 As shown, the lower slide 52 is provided with a Y-axis groove 521 extending along the Y-axis. The second drive assembly 54 is disposed within the Y-axis groove 521. Two sets of second sliding assemblies 53 are provided, one on each side of the Y-axis groove 521. The Y-axis groove 521 is recessed within the lower slide 52, reducing the space occupied by the second drive assembly 54. This further flattens the Y-axis movable platform 5, preventing assembly interference between the second drive assembly 54 and the second spindle assembly 3, and improving overall assembly convenience. This facilitates adjusting the height of the second spindle assembly 3 and aligning the second spindle 31 with the first spindle 21.

[0061] In addition, the top of the processing platform 11 is tilted, with an angle ranging from 10 to 60 degrees. The tilt of the processing platform 11 facilitates the automatic drop of debris and prevents a large accumulation of debris. Specifically, the tilt angle of the top of the processing platform 11 can be 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 degrees, or other angles between 10 and 60 degrees. Figure 1 The figure shows a preferred embodiment in which the top of the processing platform 11 is inclined at an angle of 30 degrees.

[0062] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
