[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0020] This embodiment relates to a V-shaped turret tail machine, referring to Figure 4-Figure 6 , including: a bed 100, a first high and low rail 200, a second high and low rail 300, a tail top assembly 400, a turret assembly 500 and a spindle assembly 600.

[0021] A chip removal area 110 is provided downwardly in the middle of the bed 100. A first high-low rail 200 is arranged on the upper surface of the bed 100 at one side of the chip removal area 110, and the lower part of the first high-low rail 200 faces the chip removal area 110; a second high-low rail 300 is arranged on the upper surface of the bed 100 at the other side of the chip removal area 110, and the lower part of the second high-low rail 300 also faces the chip removal area 110. The tail top assembly 400 is slidably assembled on the first high-low rail 200; the turret assembly 500 is slidably assembled on the second high-low rail 300, and the tail top assembly 400 and the turret assembly 500 are V-shaped. The spindle assembly 600 is arranged on the upper surface of the bed 100, and is located on the same side as the first high-low rail 200, and is coaxially arranged with the tail top assembly 400.

[0022] The workpiece to be processed is clamped between the main spindle assembly 600 and the tail top assembly 400 . The main spindle assembly 600 drives the workpiece to be processed to rotate. The turret assembly 500 processes the workpiece to be processed, and waste chips fall into the chip removal area 110 .

[0023] Reference Figure 1 This is the first type of tail top guide rail currently available. The first type of tail top guide rail is an inclined rail. The chip removal area of ​​this structure will increase the width of the machine tool.

[0024] Reference Figure 2This is the second type of tail top guide rail currently available. The second type of tail top rail is a flat rail. The supporting ribs in the chip discharge area of ​​this structure will affect chip discharge.

[0025] Reference Figure 3 This is the third type of tail top guide rail. The third type of tail top guide rail is the inner high and low rail. The chip removal area of ​​this structure is outside the bed. It is similar to the first structure, but it must be equipped with a chip conveyor. After adding the chip conveyor, the actual width of the machine tool will also increase.

[0026] Back to the present solution, the chip removal area 110 is arranged at the bottom of the V-shaped area, which is conducive to chip removal; and since the chip removal area 110 is located between the tail top assembly 400 and the turret assembly 500, that is, located inside the bed 100, the chip conveyor 700 can be placed under the tail top assembly 400 and the turret assembly 500, and will not increase the width of the V-shaped turret tail top machine, making the overall structure of the bed 100 compact, effectively shortening the width of the bed 100.

[0027] Reference Figure 6-Figure 10 The tail top assembly 400 includes: a tail top slider 410 slidably mounted on the first high-low rail 200; a tail top seat 420 disposed on the tail top slider 410; a tail top 430 disposed on the tail top seat 420; and a first high-low rail shield 440 disposed on the tail top slider 410 and tilted. The turret assembly 500 includes: a turret slider 510 slidably mounted on the second high-low rail 300; a turret seat 520 disposed on the turret slider 510; a turret 530 disposed on the turret seat 520; and a second high-low rail shield 540 disposed on the turret slider 510 and tilted. The lower parts of the first high-low rail shield 440 and the second high-low rail shield 540 are both oriented toward the chip removal area 110.

[0028] The bevel angle of the first high-low rail guard 440 and the bevel angle of the second high-low rail guard 540 are conducive to the entry of chips into the chip removal area 110. Since the chip removal area 110 is inside the bed 100 and can store a certain amount of chips, a chip conveyor 700 can be selected. The bevel angle of the first high-low rail guard 440 and the second high-low rail guard 540 also play a role in protecting the first high-low rail 200 and the second high-low rail 300.

[0029] Specifically in this embodiment, refer to Figure 10-11, the first high-low rail guard 440 is 20° with the horizontal plane, and the second high-low rail guard 540 is 30° with the horizontal plane, that is, the first high-low rail guard 440 and the second high-low rail guard 540 are at an angle of 130°, similar to a V-shape. The 30° bevel angle of the second high-low rail guard 540 and the 20° bevel angle of the first high-low rail guard 440 are conducive to the entry of chips into the chip discharge area 110. In other embodiments, the angle between the first high-low rail guard 440 and the horizontal plane can also be 10°, 15°, 25°, 30°, 35°, 40°, etc.; the angle between the second high-low rail guard 540 and the horizontal plane can also be 15°, 20°, 25°, 35°, 40°, 45°, 50°, etc.

[0030] Reference Figure 6-Figure 9 The tail top slider 410 is provided with two groups, one group is slidably mounted on the high rail of the first high-low rail 200, and the other group is slidably mounted on the low rail of the first high-low rail 200. The lower end of the tail top seat 420 is mounted on the two groups of tail top sliders 410, and the upper end of the tail top seat 420 is a plane parallel to the upper surface of the bed 100. The tail top 430 is mounted on the plane.

[0031] The first high-low rail 200 and the tail top seat 420 raise the installation surface of the tail top 430, shorten the distance between the tail top 430 and the center of the main shaft 620, and also shorten the distance from the force point of the tail top 430 when supporting the workpiece to the guide rail of the tail top 430, thereby improving the overall rigidity of the tail top 430.

[0032] Reference Figure 6-Figure 9 The turret sliders 510 are provided with two groups, one group is slidably mounted on the high rail of the second high-low rail 300, and the other group is slidably mounted on the low rail of the second high-low rail 300. The lower end of the turret seat 520 is mounted on the two groups of tail top sliders 410, and the upper end is an inclined surface for the installation of the second high-low rail shield 540. The turret assembly 500 specifically also includes a turret motor, etc., which will not be described in detail here.

[0033] Reference Figure 6-Figure 7 and Fig.10 The spindle assembly 600 includes: a spindle seat 610 disposed on the upper surface of the bed 100 and located on the same side as the first high-low rail 200, and a spindle 620 disposed on the spindle seat 610 and coaxially disposed with the tail top 430. The spindle assembly 600 specifically also includes a headstock and a spindle motor, etc., which will not be described in detail here.

[0034] Specifically in this embodiment, refer to Figure 7-10The first high and low rail guard 440 is located on both sides of the tail top slider 410 to cover the first high and low rail 200; the second high and low rail guard 540 is located on both sides of the turret slider 510 to cover the second high and low rail 300. The first high and low rail guard 440 and the second high and low rail guard 540 are both arranged to avoid the operation of the V-type turret tail top machine. Of course, in other embodiments, the first high and low rail guard 440 can also be arranged only on the side of the tail top slider 410 close to the main shaft 620; the second high and low rail guard 540 can also be arranged only on the side with the turret 530.

[0035] In order to assist the waste chips to fall into the chip discharge area 110, refer to Figure 4-Figure 5 The bed 100 is arranged in an inclined shape at the peripheral side of the chip removal area 110. This arrangement plays a second role in assisting chip removal.

[0036] Reference Fig.10 , the V-type turret tail top machine also includes: a chip conveyor 700. The bed 100 of the V-type turret tail top machine is also provided with a chip discharge port 120 connected to the chip discharge area 110. Part of the chip conveyor 700 is located in the chip discharge area 110, and the other part extends from one end of the bed 100, that is, from the chip discharge port 120. The chip conveyor 700 is used to collect the waste chips generated by the V-type turret tail top machine and transfer the waste chips to the chip collection vehicle 800. The chip conveyor 700 can be used in conjunction with a filtered water tank to recycle various coolants. The chip conveyor 700 includes a scraper chip conveyor, a chain plate chip conveyor, a magnetic chip conveyor, a spiral chip conveyor, and the like. In this embodiment, a chip collection vehicle 800 is also provided on the lower side of the discharge end of the chip conveyor 700. The chip collector 800 is used to collect various chips transmitted from machine tools by various chip conveyors. It is equipped with wheels at the bottom to send the chips out of the workplace for centralized cleaning. It is divided into dry and wet types. The dry type material box can be tilted to pour out the chips. The wet type is based on the dry type with a double-layer filter and an oil drain valve to separate the coolant in the chips from the chips, which plays a role in recycling and environmental protection. Chip collectors 800 with different volumes and functions can be designed according to different chip removal amounts and user requirements.

[0037] In some embodiments of the present invention, the first high-low rail 200 and the second high-low rail 300 are both integrally formed on the bed 100 , that is, the bed 100 is a V-shaped structure.

[0038] The working principle of the present invention is roughly as follows: the tail top assembly 400 on the first high-low rail 200 and the turret assembly 500 on the second high-low rail 300 are V-shaped, and the chip removal area 110 is arranged at the valley of the V-shaped area, which is conducive to chip removal; and because the chip removal area 110 is located between the tail top assembly 400 and the turret assembly 500, that is, located inside the bed 100, the chip conveyor 700 can be placed under the tail top assembly 400 and the turret assembly 500, and will not increase the width of the V-shaped turret tail top machine, so that the overall structure of the bed 100 becomes compact, and the width of the bed 100 is effectively shortened.

[0039] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
