[0012] The present invention provides a horizontal double-pallet machine tool with a tailstock. It has the following beneficial effects: 1. The horizontal double-pallet machine tool with tailstock pushes the air to the air outlet through the connecting pipe by rotating the fan blades, so that the air outlet generates a blowing airflow, which flows through the surface of the workpiece and blows downward, so that the chips cut off during processing are sucked to the left to prevent the chips from being rolled into the tool. As the length of the chips increases, the gravity and the thrust of the airflow will break the chips, avoiding the influence of curling on the processing, which can improve the processing speed.
[0013] 2. This horizontal double-pallet machine tool with tailstock uses the speed difference between the sweeping frame and the passive frame to cut the debris, so that the long debris can be broken. At the same time, the sweeping frame will swing the debris to the outside through centrifugal force. During the swinging process, the raised edge will cut the debris and further turn the debris into small debris, avoiding excessively long debris from accumulating in the processing area and affecting the cutting process, thereby improving the processing speed.
[0014] 3. The horizontal double-pallet machine tool with tailstock can transport the debris sent by the push plate to the right through the spiral push rod, and continuously squeeze the debris inside the compression tube. After the debris is compacted, it pushes the compression plate to open, and the debris falls into the receiving box under the action of the inclined surface of the compression plate and the guide guard plate to collect and process the debris, which compresses the space occupied by the debris, reduces the frequency of processing the debris during shutdown, and indirectly improves the processing speed.
[0015] 4. The horizontal double-pallet machine tool with tailstock can support the broken chips by sweeping the chips by the moving frame and cutting blade. The spiral push rod can squeeze the chips inside the compression tube, which can make the chips closer to each other and promote the compaction of the chips. It can further effectively reduce the space occupied by the chips, and then reduce the frequency of processing the chips during shutdown, which can indirectly improve the processing speed.

DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0020] Example 1: Please refer to Figure 1-5 The present invention provides a technical solution: a horizontal double-pallet machine tool with a tailstock, comprising a spindle box 1, a machining base 2 is fixedly connected to the right side of the spindle box 1, a tailstock slide 31 is fixedly connected to the top of the machining base 2, a tailstock body 32 is movably connected to the top of the tailstock slide 31, a secondary feed frame 39 is fixedly connected to the top of the machining base 2, an anti-roll mechanism 4 is fixedly connected to the top of the machining base 2, a compression mechanism 5 is fixedly connected inside the machining base 2, a first X feed box 33 is movably connected to the top of the machining base 2, a first tool support plate 35 is movably connected to the top of the first X feed box 33, a second X feed box 34 is movably connected to the front of the secondary feed frame 39, and a second tool support plate 36 is movably connected to the front of the second X feed box 34; The anti-roll mechanism 4 comprises: A pusher guide rail 403, which is fixedly connected to the top of the processing base 2; A box pusher 402, the box pusher 402 is movably connected to the outer wall of the pusher guide rail 403; The pneumatic box 401 is movably connected to the outer wall of the pusher guide rail 403, and the driving motor 404 is fixedly connected to the box pusher 402.
[0021] The second tool support plate 36 is fixedly connected to the second turret 37 on the front side, and the first tool support plate 35 is fixedly connected to the first turret 38 on the top. There is a driving structure inside the second tool support plate 36 that allows the second tool support plate 36 to slide up and down on the surface of the second X feed box 34. There is a driving structure inside the first tool support plate 35 that allows the first tool support plate 35 to slide back and forth on the top of the first X feed box 33. A claw fixedly connected to the spindle in the spindle box 1 is arranged on the right side of the spindle box 1.
[0022] The tools required for processing are fixed on the second turret 37 and the first turret 38 respectively, and the workpiece to be processed is clamped by a claw. The spindle box 1 drives the horizontal spindle inside to drive the claw to rotate the workpiece and feed the tool to perform turning processing on the workpiece.
[0023] A driving motor 404 is fixedly connected inside the pusher guide rail 403, a fan blade 405 is fixedly connected to the top of the driving motor 404, the driving motor 404 and the fan blade 405 output shaft are fixedly connected, a filter plate 406 is fixedly connected to the top of the pusher guide rail 403, a connecting pipe 407 is fixedly connected to the outer wall of the filter plate 406, an air outlet head 408 is fixedly connected to the left side of the second tool support plate 36, and the connecting pipe 407 is fixedly connected to the air outlet head 408.
[0024] When turning is performed, the box pusher 402 will push the pneumatic box 401 along the pneumatic box 401, so that the pneumatic box 401 is at the bottom of the workpiece processing position, and at the same time, the drive motor 404 is started. The drive motor 404 will rotate with the fan blades 405, and continuously push the air to the air outlet head 408 through the connecting pipe 407, so that the air outlet head 408 generates a blowing airflow, and the airflow flows through the surface of the workpiece and blows downward. The downward airflow will form a low-pressure area, which will first suck the cut debris to the left to prevent the debris from being rolled into the tool, and blow the debris generated by the processing downward to prevent the debris from rolling up. When the debris is pushed by the wind, as the length of the debris increases, the gravity and the thrust of the airflow will cause the debris to break.
[0025] A sweeping frame 409 is disposed on the top of the filter plate 406 , and the sweeping frame 409 is fixedly connected to the top of the fan blade 405 .
[0026] The fan blades 405 are driven by the driving motor 404 to suck airflow at the top of the filter plate 406 , and the fan blades 405 will synchronously rotate with the sweeping frame 409 to sweep the top of the filter plate 406 to prevent the top of the filter plate 406 from being blocked by debris.
[0027] The top of the sweeping frame 409 is movably connected to a passive frame 410 , the bottom of the passive frame 410 is located at the top of the sweeping frame 409 and is fixedly connected to a cutting blade 411 , and the outer wall of the sweeping frame 409 is provided with a raised cutting edge 412 .
[0028] When the sweeping frame 409 is driven to rotate, since the passive frame 410 is rotatably connected to the sweeping frame 409, the sweeping frame 409 will not rotate at the same speed as the passive frame 410. There will be a speed difference between the sweeping frame 409 and the passive frame 410. This speed difference will cause the debris falling onto the top of the filter plate 406 to be cut by the sweeping frame 409 and the cutting blade 411 at the bottom of the passive frame 410, so as to break the long strips of debris. At the same time, the sweeping frame 409 will swing the debris to the outside through centrifugal force. During the swinging process, the raised cutting edge 412 will cut the debris, further turning the debris into small pieces, thereby preventing excessively long debris from accumulating in the processing area and affecting the cutting process.
[0029] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The compression mechanism 5 includes a conveyor belt 501 . The conveyor belt 501 is arranged inside the processing base 2 . A driving structure for driving the conveyor belt 501 is arranged inside the spindle box 1 . A pushing plate 502 is arranged on the outer wall of the conveyor belt 501 .
[0030] During processing, the conveyor belt 501 is driven to move by the driving structure inside the spindle box 1 , and the conveyor belt 501 drives the push plate 502 on the surface to sweep the debris toward the front.
[0031] A screw push rod 503 is arranged inside the processing base 2 in front of the conveyor belt 501 , and a driving structure for driving the screw push rod 503 to rotate is arranged inside the spindle box 1 .
[0032] The conveyor belt 501 drives the push plate 502 to sweep the debris toward the screw push rod 503. The screw push rod 503 is driven to rotate by the driving structure inside the spindle box 1. The screw push rod 503 transports the debris sent by the push plate 502 to the right.
[0033] A compression tube 504 is fixedly connected to the outside of the screw push rod 503 inside the spindle box 1, a compression plate 505 is movably connected to the right side of the processing base 2, a guide guard plate 506 is fixedly connected to the top of the compression tube 504 on the left side of the compression plate 505, a pressure frame 507 is fixedly connected to the right side of the compression plate 505 on the right side of the processing base 2, a spring 508 is fixedly connected to the right side of the compression plate 505, and the right side of the spring 508 is fixedly connected to the pressure frame 507, and a receiving box 509 is arranged at the bottom of the compression plate 505.
[0034] The debris is continuously transported to the right by the spiral push rod 503, and the debris is continuously squeezed inside the compression tube 504. After the debris is cut by the sweeping frame 409 and the cutting blade 411, it will play a supporting role between the broken debris, allowing the debris to be closer to each other and promote the compaction of the debris. After the debris is compacted, it will be pushed by the spiral push rod 503 to push the compression plate 505 open, and the compression plate 505 will squeeze the spring 508 to the right. The spring 508 will keep the compression plate 505 at a certain leftward pressure. The compression plate 505 is squeezed to rotate around the part connected to the processing base 2 to form an inclined surface. Under the action of the inclined surface and the guide guard plate 506, the debris will fall into the receiving box 509 to collect and process the debris.
[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
