[0048] A feed system 3, the feed system 3 is arranged at the upper part of the lathe housing 1, and is used to control the processing tool for turning, milling, and drilling;

[0049] The feed system 3 includes a first feed component 301, a second feed component 302, a third feed component 303, and a motor base 307. The first feed component 301 is used to control the lateral movement of the second feed component 302. The second feed component 302 is used to control the longitudinal movement of the third feed component 303. The third feed component 303 is used to control the vertical movement of the motor base 307. A first servo motor 304 is installed on the motor base 307.

The turning tool 3053 is arranged along the radial direction of the tool disc 306.

[0050] Reference Figure 3 , the first feed component 301 can control the partial axial movement of the second feed component 302, enabling the tool assembly 305 to approach or move away from the two spindle components 2. The second feed component 302 can control the longitudinal movement of the third feed component 303, thereby controlling the synchronous longitudinal movement of the tool assembly 305.

[0051] The first feed component 301, the second feed component 302, and the third feed component 303 all include a moving housing 602. A moving lead screw 603 is rotatably installed in the moving housing 602. A second servo motor 601 is fixedly installed on the outside of the moving housing 602. The output end of the second servo motor 601 is fixedly connected to the moving lead screw 603. A moving seat 604 is threadedly connected to the moving lead screw 603. The moving seat 604 is slidably engaged with the moving housing 602.

[0052] Reference Figure 3 , during the moving operation, the second servo motor 601 works under the control of the lathe control panel, driving the moving lead screw 603 to rotate. The moving lead screw 603 can drive the moving seat 604 to move. The moving seat 604 can move along the length direction of the moving housing 602 to achieve the purpose of controlling the movement.

[0053] The chip removal component 5 is provided at the right part of the lathe housing 1 and is used for sucking and removing chips.

[0054] The chip removal assembly 5 includes an upper baffle 502. Symmetrically arranged moving channels 5021 are provided on the upper baffle 502. A core-pulling assembly for controlling the movement of one of the main shaft components 2 along the axis of the workpiece is provided inside the upper baffle 502.

[0055] Reference Figure 1 , Figure 8 , Figure 13 , Figure 14 The upper baffle 502 is used to block debris, so that the debris can only enter the collection housing 503 through the moving channels 5021, providing a block for the driving lead screw 705 and the slider 702 parts to prevent debris from directly falling on the driving lead screw 705 and the slider 702.

[0056] The core-pulling assembly includes a servo motor three 706 fixedly installed on the upper baffle 502. The output end of the servo motor three 706 is fixedly connected to a driving lead screw 705. A moving member 7 is provided on the driving lead screw 705. A main guide rail 506 is provided outside the air blowing member 505. The moving member 7 includes a chip blocking plate 701. Symmetrically and fixedly connected to the lower part of the chip blocking plate 701 are sliders 702. The sliders 702 are slidably matched with the main guide rail 506. Symmetrically and fixedly connected to the upper part of the chip blocking plate 701 are protruding strip blocks 703. A lead screw sleeve 704 is fixedly connected to the middle part of the chip blocking plate 701. The lead screw sleeve 704 is in threaded cooperation with the driving lead screw 705. The protruding strip blocks 703 pass through the moving channels 5021 and are fixedly connected to a mounting member 501. The mounting member 501 includes a mounting seat 5011. A support wheel 5012 is installed at the lower part of the mounting seat 5011.

[0057] Reference Figure 8 , Figure 14 During the core-pulling operation, the servo motor three 706 works under the action of the control panel of the lathe itself, driving the driving lead screw 705 to rotate. The driving lead screw 705 drives the lead screw sleeve 704 to move. The lead screw sleeve 704 drives the chip blocking plate 701 and the sliders 702 to move synchronously as a whole, so as to be able to drive the upper mounting member 501 and the right main shaft component 2 as a whole to approach the left main shaft component 2, and be able to drive the workpiece to move along the axis direction, maximizing the utilization of the workpiece raw material. The support wheel 5012 can roll on the upper baffle 502, so as to be able to overcome the weight of the main shaft component 2 and reduce the overall load of the moving member 7. The protruding strip blocks 703 can block a part of the moving channels 5021, so that the debris can only enter the collection housing 503 from the unblocked part.

[0058] A collection housing 503 is fixedly connected below the upper baffle 502. A collection chamber 5031 is provided inside the collection housing 503. A suction pipe 504 is fixedly connected to the bottom of the collection chamber 5031. The suction pipe 504 is connected to an external suction device. Guide rails 5032 are symmetrically provided outside the collection chamber 5031. Air blowing members 505 for generating horizontal and vertical airflows are symmetrically provided outside the guide rails 5032.

[0059] Reference Figure 10 、 Figure 8 When the peripheral suction device is working, a negative pressure can be generated in the collection chamber 5031 through the suction pipe 504, so that debris can enter the collection chamber 5031 and then be sucked into the suction device from the suction pipe 504; the guide rail 5032 is used to guide the telescopic direction of the telescopic member 8.

[0060] The blowing member 505 includes a blowing housing 5051. End blowing holes 5053 are provided at both ends of the blowing housing 5051. A contact inclined surface 5056 and a support plane 5055 are provided on the upper surface of the blowing housing 5051. Oblique blowing holes 5052 are evenly provided on the contact inclined surface 5056. An air inlet pipe 5054 is fixedly connected to the end of the blowing housing 5051, and the air inlet pipe 5054 is in communication with the peripheral air source;

[0061] Reference Figure 12 During the blowing operation, the air flow generated by the peripheral air source enters the blowing housing 5051 from the air inlet pipe 5054, and the gas can be blown out from the oblique blowing holes 5052 and the end blowing holes 5053 at the same time. The air flow blown out from the end blowing holes 5053 will act on the wind receiving block 803 of the telescopic member 8, so that the telescopic member 8 is in the extended state, thereby being able to block the gap at the guide rail 5032 and prevent debris from entering the guide rail 5032; the oblique blowing holes 5052 are used to generate an air flow in an inclined direction, so that the air flow blows towards the collection chamber 5031, so that the debris can only enter the collection chamber 5031; and the blowing housing 5051 can provide a blocking effect on the slider 702 to further ensure that no debris enters the slider 702.

[0062] A telescopic member 8 is symmetrically and slidably connected to the guide rail 5032. The telescopic member 8 is closely attached to the guide rail 5032 under the action of the air flow blown out by the blowing member 505, and is used to block the movement space of the debris;

[0063] The telescopic member 8 includes a telescopic sleeve 801. A telescopic portion 802 is provided on the telescopic sleeve 801. A mating groove 804 is provided at the lower part of the telescopic sleeve 801. The mating groove 804 is slidably mated with the guide rail 5032. One end of the telescopic sleeve 801 close to the middle of the collection housing 503 is fixedly connected with a wind receiving block 803;

[0064] Reference Figure 11 、 Figure 8, the telescopic sleeve 801 has a telescopic function. When the telescopic part 802 is in the retracted state, it is in a contracted state, and when in the extended state, it is in an extended state. Therefore, it can fit the space gap above the blowing part 505. The wind-receiving block 803 will stop when it contacts the side surface of the chip-blocking plate 701 under the push of the air flow. Therefore, it is ensured that there is no gap between the chip-blocking plate 701 and the wind-receiving block 803, ensuring that the overall blocking effect of the telescopic sleeve 801 is good; and an air flow channel is reserved between the wind-receiving block 803 and the contact inclined surface 5056 for the air flow to pass through in the blocking state. After passing through the air flow channel, the air flow will be blown out from the gap below the chip-blocking plate 701, preventing chips from entering the blowing part 505 from the gap below the chip-blocking plate 701; when the moving part 7 moves, the closer side will push the wind-receiving block 803 to move, causing the telescopic sleeve 801 on the closer side to contract. Since the wind-receiving block 803 on the farther side lacks the restriction of the chip-blocking plate 701, it will further extend, thus ensuring that the wind-receiving blocks 803 on both sides always closely adhere to the chip-blocking plate 701. And there is a slight height difference between the telescopic part 802 and the main body of the telescopic sleeve 801. This part of the height difference can also be used for air flow circulation. The larger the extended state of the telescopic sleeve 801, the smaller this part of the height difference, and the smaller the space for air flow to pass through. On the contrary, the smaller the extended state of the telescopic sleeve 801, the larger this part of the height difference, and the larger the space for air flow to pass through. Therefore, the air flow passing amounts of the telescopic parts 802 of the telescopic sleeves 801 on both sides are different, which also meets the needs during processing. When the two spindle components 2 are closer, the length of the moving channel 5021 through which chips can enter is smaller, the amount of chips entering the moving channel 5021 per unit distance is larger, and the probability of chips flying laterally is higher. Therefore, a large air flow passing amount can provide wind resistance for the lateral flying of chips, making the chips only fall into the collection cavity 5031; when the two spindle components 2 are far away from each other, the length of the moving channel 5021 through which chips can enter is larger, the amount of chips entering the moving channel 5021 per unit distance is smaller, and the probability of chips flying laterally is lower. At this time, a small air flow passing amount can meet the wind resistance needs of the small amount of laterally flying chips, ensuring the maximum utilization of the air flow and ensuring that the chips can be completely sucked away with good chip suction efficiency.

[0065] Working principle: During turning, milling, and drilling operations, the spindle component 2 is used to process the workpiece and control the workpiece to rotate. The feed system 3 is used to control the required tool to the cutting point to complete the turning, milling, and drilling processing of the workpiece. Among them, the program programming control part can implement the existing control panel;

[0066] When sucking debris, when the peripheral suction device is working, a negative pressure can be generated in the collection chamber 5031 through the suction pipe 504, so that the debris can enter the collection chamber 5031 and then be sucked into the suction device through the suction pipe 504. During the blowing operation, the air flow generated by the peripheral air source enters the blowing housing 5051 through the air inlet pipe 5054, and the gas can be blown out simultaneously from the inclined blowing holes 5052 and the end blowing holes 5053. The air flow blown out from the end blowing holes 5053 acts on the wind-receiving block 803 of the telescopic member 8, so that the telescopic member 8 is in the extended state, thereby being able to block the gap at the guide rail 5032 and prevent debris from entering the guide rail 5032; the inclined blowing holes 5052 are used to generate an air flow in an inclined direction, so that the air flow blows towards the collection chamber 5031, so that the debris can only enter the collection chamber 5031; and the blowing housing 5051 can provide a blocking effect on the slider 702, further ensuring that no debris enters the slider 702;

[0067] The telescopic sleeve 801 has the function of telescoping. When the telescopic part 802 is in the retracted state, it is in the contracted state, and when it is in the extended state, it is in the extended state. Therefore, it can fit the space gap above the blowing member 505. When the wind-receiving block 803 is pushed by the air flow, it will stop only when it contacts the side surface of the debris-blocking plate 701. Therefore, it is ensured that there is no gap between the debris-blocking plate 701 and the wind-receiving block 803, and the overall blocking effect of the telescopic sleeve 801 is good; and an air flow channel is reserved between the wind-receiving block 803 and the contact inclined surface 5056 for the air flow to pass through in the blocking state. After passing through the air flow channel, the air flow will be blown out from the gap below the debris-blocking plate 701, preventing debris from entering the blowing member 505 from the gap below the debris-blocking plate 701, so that the debris completely enters the collection housing 503, preventing the debris from affecting the relevant components and improving the durability of the overall lathe.
