[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 13 As shown, the embodiment of the present invention provides a dual-spindle turning and milling compound CNC machine tool, including a base 1, a No. 1 spindle box 2 and a No. 2 spindle box 3 slidably mounted on the top of the base 1, a movable frame 4 is slidably mounted on the top of the base 1, the movable frame 4 is sleeved on the outside of the No. 1 spindle box 2 and the No. 2 spindle box 3, a tool holder is fixedly arranged inside the movable frame 4, a connecting head 5 is movably sleeved on the front of the movable frame 4, a pushing mechanism 6 is fixedly arranged on the front of the movable frame 4, the pushing mechanism 6 is fixedly connected to the connecting head 5, and a collecting device is fixedly arranged at one end of the connecting head 5, the collecting device includes: a baffle 7, a material guide assembly 9 and a pulling assembly 10, the number of the baffles 7 is two, an intermediate frame 8 is fixedly arranged between the two baffles 7, one baffle 7 is fixedly connected to the connecting head 5, the material guide assembly 9 is elastically connected to both sides of the intermediate frame 8, and the pulling assembly 10 pulls the two groups of material guide assemblies 9 to swing together on the side of the intermediate frame 8;

[0039] An air supply assembly 13 is fixedly provided at the other end of the connector 5 , and the pressurized air output by the air supply assembly 13 pushes the pulling assembly 10 to move laterally.

[0040] Embodiment 1: During use, the workpiece to be processed is fixed on the spindle clamping part of the No. 1 spindle box 2, so that the movable frame 4 is moved between the No. 1 spindle box 2 and the No. 2 spindle box 3, and the air supply component 13 is started first. The air pump 131 inputs the pressurized air into the No. 1 air channel 15 through the control valve 132, and then passes into the sleeve hole 14. The pressurized air is between the fixed ring 104 and the movable plug 103 of the pulling component 10. The pressurized air acts on the inner side of the movable plug 103, pushing the movable plug 103 to move outward in the sleeve hole 14. The connecting rod 102 is moved horizontally, thereby driving the connecting rope 101 to move. The connecting rope 101 pulls the guide plate 91 in the guide assembly 9, so that the guide plate 91 swings upward around the fixed axis 92, and at the same time compresses the spring 93, so that the two sets of guide assemblies 9 are brought together and swing to a nearly vertical state, and the pushing mechanism 6 is started, so that the electric push rod 2 drives the connecting head 5 to move, and the intermediate frame 8 and the baffle 7 move horizontally along the front opening of the movable frame 4 and are inserted between the No. 1 spindle box 2 and the No. 2 spindle box 3, and the material guiding is realized. The position of the component 9 is adjusted. When the guide component 9 moves to between the first spindle box 2 and the second spindle box 3 and is located below the workpiece, the air supply is stopped, and the spring 93 is elastically reset, so that the guide component 9 swings downward to reset and abuts against the side wall of the spindle box. When processing is performed, the chips and cutting fluid fall fully downward on the guide plate 91 and are guided to the bottom of the intermediate frame 8 and the space between the composite processing component 11. At the same time, the cutting fluid penetrates into the storage chamber 17 through the penetration groove 113. When the first spindle box 2 and the second spindle box are in contact with each other, the cutting fluid penetrates into the storage chamber 17 through the penetration groove 113. When the two spindle boxes 3 move relative to each other, when they are close to each other, the moving spindle box pushes the guide plate 91 on the corresponding side to swing upwards. When one spindle box moves away from each other, the spring 93 further elastically pushes the guide plate 91 to swing downwards. The top of the guide plate 91 always presses against the inner wall of the spindle box to maintain sufficient collection on the top. When the collection and processing is completed, the air supply component 13 is started again, and the two groups of guide components 9 are actively closed, and then withdrawn from between the No. 1 spindle box 2 and the No. 2 spindle box 3 to complete the chip collection, and at the same time complete the collection and filtration storage of the cutting fluid.

[0041] Firstly, by utilizing the introduction of pressurized air from the air supply assembly 13, the pulling control of the pulling assembly 10 is controlled to realize the swing control of the material guide assemblies 9 on both sides of the intermediate frame 8, thereby adapting to the movement of the movable frame 4, and realizing the insertion from one side to between the two side spindle boxes, and cooperating with the elastically connected material guide assembly 9, after canceling the pressure air control, the material guide assembly 9 is opened outward, and rests against the inner wall of the spindle box, and upwardly receives the processing debris on the top to realize debris collection, and when the displacement of the spindle boxes on both sides changes during the processing, it can not only push the material guide assembly 9 to follow the swing, but also adapt to the outward movement of the spindle box. During the processing, it adapts to the position adjustment of the spindle box, and always maintains sufficient reception and collection on the top, which greatly improves the collection effect, avoids the debris from being ejected everywhere and difficult to clean, and has a good use effect.

[0042] In addition, in conjunction with the guided collection of the material guide component 9, the penetration groove 113 in the composite processing component 11 is used to achieve filtering and collection, and the cutting fluid is collected and concentrated in the storage chamber 17, so as to separate and collect debris and cutting fluid, avoid large-scale splashing and dispersion of cutting fluid, and improve the cleanliness of the interior of the machine tool. The cutting fluid after filtration and collection is convenient for centralized transfer and subsequent treatment, so as to avoid the scattered cutting fluid from contaminating the machine tool and the site, and can be recycled and processed in conjunction with the subsequent processing mechanism, with good use effect.

[0043] Embodiment 2: When the collection and processing are completed and the machine needs to be shut down, as the material guide assemblies 9 on both sides swing up and close, the control valve 132 is started, and while the No. 1 air channel 15 is kept closed and sealed, the pressurized air is guided to the connecting pipe 12, and the heating pipe in the No. 2 air channel 16 is started, so that the hot pressurized air heated inside the No. 2 air channel 16 is passed into the middle cavity 114, and the hot pressurized air is blown out along the jet hole 112 at the upper end of the top slope of the connecting frame 111, and the hot air blows out to act on the No. 1 spindle box 2 and the No. 2 spindle box 3, and the space and surface between the two groups of spindle boxes are dried with hot air, completing the drying and further cleaning process.

[0044] First, by reusing the composite processing component 11 and the air supply component 13, in conjunction with the switched air supply processing, the pressurized air is heated and redirected to the composite processing components 11 on both sides, and after being folded together on the material guide component 9, the two groups of spindle boxes are purged with hot air through the inclined hot air spray. On the one hand, hot air drying of the surface of the equipment structure is achieved, and on the other hand, the purging and cleaning of pressurized air is achieved. When the processing is completed and the machine is ready to be shut down, the cleaning and drying processing after rapid connection is achieved, which improves the maintenance efficiency and has a good use effect.

[0045] Among them, a transverse movement control part is fixedly provided at one end of the base 1, and the transverse movement control part is an electric push rod 1. The transverse movement control part controls the movable frame 4 to move back and forth horizontally.

[0046] By utilizing the transverse movement control unit to push the movable frame 4 to move, the internal tool holder is driven to move, and the processing is realized in cooperation with the main shaft. In addition to the electric push rod 2, the transverse movement control unit can also be a hydraulic push rod or a lead screw to realize transverse reciprocating movement.

[0047] The pushing mechanism 6 includes an electric push rod 2 and a connecting plate. The electric push rod 2 is fixedly connected to the connecting head 5 through the connecting plate and controls the reciprocating movement of the connecting head 5.

[0048] The pushing mechanism 6 realizes the support, fixation and lateral movement control of the connecting head 5. In addition to the electric push rod 2, it can also be realized by a screw or a hydraulic push rod. When the guide assembly 9 is moved to the outside, the movable frame 4 can slide stably and adapt to the processing area after insertion for receiving and collecting.

[0049] Among them, the material guide assembly 9 includes a material guide plate 91, a fixed shaft 92 and a spring 93. The fixed shaft 92 is fixed between the two groups of baffles 7. The lower end of the material guide plate 91 is rotatably sleeved on the outer surface of the fixed shaft 92. One end of the spring 93 is fixedly connected to the material guide plate 91, and the other end is fixedly connected to the intermediate frame 8. A guide groove is provided on the inner side surface of the material guide plate 91.

[0050] The material guide assembly 9 can adapt to the displacement change of the spindle box by the elastic compressible upward swing and elastic reset downward swing of the spring 93, and is always open under the workpiece to receive the debris and cutting fluid. The guide groove provides a guiding effect to avoid leakage from the side.

[0053] Among them, the pulling assembly 10 includes a connecting rope 101, a connecting rod 102, a movable plug 103 and a fixed ring 104.

One end of the connecting rope 101 is fixedly connected to the guide plate 91, and the other end movably passes through the side of the intermediate frame 8 and is fixedly connected to the other end of the connecting rod 102.

[0054] The pulling assembly 10 realizes the pulling of the two groups of material guide assemblies 9 through the two groups of connecting ropes 101 at one end of the connecting rod 102. Under the pulling effect, the springs 93 are actively compressed and brought closer to each other, thereby reducing the volume share and facilitating the horizontal passage through the movable frame 4.

[0055] Among them, the air supply component 13 includes an air pump 131 and a control valve 132. The air pump 131 is fixed at the end of the connecting head 5. The control valve 132 is fixedly connected to the air outlet end of the air pump 131. The control valve 132 has two air outlet ends, one of which is fixed on the end face of the connecting head 5 and is connected to the No. 1 air channel 15.

[0056] The air supply component 13 realizes different effect control by using two air outlet ends to discharge air respectively. When it is passed into the No. 1 air channel 15, pulling control is realized, and after it is passed into the No. 2 air channel 16, subsequent hot air blowing and drying treatment are realized.

The air jet hole 112 array is opened on the top of the connecting frame 111 and is located on the inclined surface. The air jet hole 112 is connected to the intermediate cavity 114, and a connecting pipe 12 is fixedly connected between the connecting head 5 and the connecting frame 111, and the two ends of the connecting pipe 12 are respectively connected to the No. 2 air channel 16 and the intermediate cavity 114.

[0058] The heating pipe is used to heat the air volume in the second air channel 16 to achieve a drying effect, and the composite processing component 11 realizes auxiliary collection, cutting fluid separation and filtration, and hot air inclined blowing.

[0059] Among them, the penetration groove 113 is opened at the bottom of the inner surface of the connecting frame 111 and is connected to the storage cavity 17. The storage cavity 17 is opened in the bottom inner wall of the connecting frame 111 and the bottom inner wall of the intermediate frame 8. The end of the intermediate frame 8 is provided with an outlet hole, which is connected to the storage cavity 17. A sealing plug is threadedly sleeved in the outlet hole.

[0060] The storage chamber 17 stores the filtered cutting fluid and cooperates with the outlet hole and the sealing plug (not shown in the figure) to discharge the filtered cutting fluid, thereby achieving filtering and collection.

[0061] The working principle and use process of the present invention are as follows: during use, the workpiece to be processed is fixed on the spindle clamping part of the No. 1 spindle box 2, so that the movable frame 4 is moved between the No. 1 spindle box 2 and the No. 2 spindle box 3, and the air supply component 13 is started first. The air pump 131 inputs pressurized air into the No. 1 air channel 15 through the control valve 132, and passes it into the sleeve hole 14. The pressurized air is between the fixed ring 104 and the movable plug 103 of the pulling component 10. The pressurized air acts on the inner side of the movable plug 103, pushing the movable plug 103 to move outward in the sleeve hole 14, driving the connecting rod 102 to move horizontally, thereby driving the connecting rope 101 to move, and the connecting rope 101 pulls the guide plate 91 in the guide component 9 , so that the material guide plate 91 swings upward around the fixed axis 92, and at the same time compresses the spring 93, so that the two sets of material guide components 9 are close to each other and swing to a nearly vertical state, and the pushing mechanism 6 is started, so that the electric push rod 2 drives the connecting head 5 to move, and the intermediate frame 8 and the baffle plate 7 move laterally along the front opening of the movable frame 4 and are inserted between the No. 1 spindle box 2 and the No. 2 spindle box 3, and the position adjustment of the material guide component 9 is realized. When the material guide component 9 moves between the No. 1 spindle box 2 and the No. 2 spindle box 3 and is located below the workpiece, the air supply is stopped, and the spring 93 is elastically reset, so that the material guide component 9 swings downward to reset and presses against the side wall of the spindle box on the side. When processing is carried out, the debris and cutting fluid are fully pushed downward It falls on the guide plate 91 and is guided to the space between the bottom of the intermediate frame 8 and the composite processing component 11. At the same time, the cutting fluid penetrates into the storage chamber 17 through the penetration groove 113. When the No. 1 spindle box 2 and the No. 2 spindle box 3 move relative to each other, when they are close, the moving spindle box pushes the guide plate 91 on the corresponding side to swing upward. When one side of the spindle box moves away, the spring 93 further elastically pushes the guide plate 91 to swing downward. The top of the guide plate 91 always presses against the inner wall of the spindle box to maintain full collection on the top. When the collection and processing is completed, the air supply component 13 is started again, and the two sets of guide components 9 are actively closed, and then withdrawn from between the No. 1 spindle box 2 and the No. 2 spindle box 3 to complete the debris collection. , and at the same time complete the collection, filtration and storage of the cutting fluid; when the collection and processing are completed and the machine needs to be shut down, as the material guide assemblies 9 on both sides are swung up and closed, the control valve 132 is started, and while maintaining the closed seal of the No. 1 airway 15, the pressurized air is guided to the connecting pipe 12, and the heating pipe in the No. 2 airway 16 is started, so that the hot pressure air heated inside the No. 2 airway 16 is passed into the middle cavity 114, and the hot pressure air is blown out along the jet hole 112 at the upper end of the top slope of the connecting frame 111, and the hot air blows out to act on the No. 1 spindle box 2 and the No. 2 spindle box 3, and the space and surface between the two groups of spindle boxes are dried with hot air, completing the drying and further cleaning process.
