[0041] Referring to the attached Figure 23 as shown, when the profile 100 is sawed as a door and window material, Figure 23 the dashed line in the upper figure in the middle is the cutting line, that is, a certain length of profile needs to be cut into several door and window materials. After sawing, the two door and window materials are pulled apart by a certain distance in the clamped state, and at the same time, the end faces of the two door and window materials are milled, Figure 23 the dashed frame line in the lower figure in the middle is the state line of end face milling, and the circles in the figure are the positions of drilling. There is no device that can achieve the above actions yet.

[0042] Referring to Figure 2 as shown, the present invention provides an embodiment of a profile sawing, milling and drilling integrated machine. For the convenience of description, the front and rear positions of this embodiment are defined by the left and right positions in Figure 2 . The profile enters from the right side of Figure 2 and exits from the left side. Moreover, the following connections and installations can be understood as direct connections or indirect connections. The meaning of indirect connection is that two components can be connected or installed through an intermediate component. This embodiment consists of three major parts: a loading and feeding device, a sawing and milling part, and a feeding and unloading device. The loading and feeding device can uniformly and automatically feed the profile into the sawing and milling part for sawing, milling and drilling, and the feeding and unloading device can take out and sequentially unload the profile after sawing and drilling. The following describes the above three major parts with reference to the attached drawings.

[0043] Referring to Figures 2 to 5 as shown, the figure schematically shows Figure 1An embodiment of a milling part in an embodiment, which includes a frame 1. There is a processing support table 18 on the frame 1 for the longitudinal movement of profiles. There is a profile channel for the movement of profiles on the processing support table 18. In this embodiment, the above-mentioned profile channel can be the upper surface of the processing support table 18. Of course, a groove-shaped profile channel can also be set separately. The frame 1 is connected with a drilling and milling table 2 and a sawing table 3 correspondingly located on both sides of the profile channel. A drill bit clamp 4 driven by a drilling motor and a milling shaft 5 driven by a milling motor are installed on the drilling and milling table 2. Different types of drill bits can be installed on the drill bit clamp. At least one horizontally arranged milling cutter disk 6 is installed on the milling shaft 5. When multiple milling cutter disks 6 are set, the multiple milling cutter disks are arranged at intervals, and multiple notches can be milled on the end face of the profile at the same time. Four milling cutter disks are shown in this embodiment. After sawing is completed, the two profiles can be pulled apart by a certain distance. The above-mentioned milling cutter disks can simultaneously perform end face milling on the two end faces of the front and rear profiles, greatly improving work efficiency. A sawing power shaft driven by a sawing motor is installed on the sawing table 3, and a sawing blade 7 is installed on the sawing power shaft. A sawing sliding power mechanism for sliding the sawing table 3 close to and away from the profile channel is installed on the frame. A drilling and milling sliding power mechanism for sliding the drilling and milling table to make the drill bit clamp and the milling cutter disk close to and away from the profile channel is also installed on the frame. In this embodiment, the above-mentioned sawing sliding power mechanism includes a sawing cylinder 8 connected to the frame. The sawing table 3 is located on one side of the profile channel and is horizontally slidably connected to the frame. The piston rod of the sawing cylinder is connected to the sawing table and can drive the sawing table to slide horizontally. When the profile passes through the above-mentioned profile channel, the sawing cylinder 8 drives the sawing table 3 to slide horizontally and close to the profile channel. The above-mentioned sawing blade 7 can saw off the profile. After sawing is completed, the sawing table slides horizontally away from the profile channel. The above-mentioned drilling and milling sliding power mechanism includes a lower sliding frame 9 horizontally slidably connected to the frame 1 and driven by a lower power machine. A middle sliding frame 10 longitudinally slidably driven by a middle power machine is connected to the lower sliding frame 9. An upper sliding frame 11 vertically slidably driven by an upper power machine is connected to the middle sliding frame 10. The drilling and milling table 2 is connected to the upper sliding frame 11. The above-mentioned structure of driving the sliding by power can adopt the way of a servo motor. For example, a power lead screw is installed on the servo motor. Threaded nuts screwed on the power lead screw are installed on the above-mentioned respective sliding frames. Of course, the power driving method of a cylinder can also be adopted. The above-mentioned respective sliding frames are slidably connected by a matching structure of a slider and a guide rail. The piston rod of the cylinder is connected to the sliding frame that needs to slide. The specific structure thereof will not be described in detail here. Its purpose is to accurately realize the up, down, horizontal and vertical position movements of the drilling and milling table, so as to facilitate accurate end face milling and drilling work.

[0044] Refer to Figures 2 to 5As shown, in this embodiment, a pressing and clamping device capable of pressing the profile is connected to the processing support table 18. The pressing and clamping device includes a sliding column 12 vertically slidably connected to the processing support table 18. The sliding column 12 is driven by a pressing cylinder 15 to vertically slide. A pressing and clamping plate 13 is connected to the sliding column 12. A clamping shaft extending downward is installed on the pressing and clamping plate 13. A freely rotatable clamping sleeve 14 is rotatably connected to the clamping shaft. A longitudinally extending guide plate is fixedly connected to the processing support table 18. The lower surface of the pressing and clamping plate cooperates with the upper surface of the processing support table to press the profile, and the clamping sleeve 14 cooperates with the guide plate to clamp the profile. When the pressing cylinder is driven, the sliding column slides downward. The lower surface of the above-mentioned pressing and clamping plate cooperates with the upper surface of the processing support table to press the profile. At the same time, the clamping sleeve 14 cooperates with the guide plate to clamp the profile. Therefore, the profile can be accurately clamped and positioned, thus ensuring the processing accuracy of the profile.

[0045] Referring to Figures 6 to 9 As shown, the present invention provides another embodiment. Its basic structure is the same as that of the above embodiment. The pressing and clamping device is not shown in the figure. The difference is that the sawing and sliding power mechanism includes a sawing cylinder 8 connected to the machine frame. The sawing table 3 is located below the profile channel and is vertically slidably connected to the machine frame. The piston rod of the sawing cylinder is connected to the sawing table and can drive the sawing table to vertically slide. That is to say, in this embodiment, the sawing table 3 saws the profile by sliding up and down. The other structures of this embodiment will not be described in detail here.

[0046] Referring to Figures 10 to 13 As shown, the present invention provides another embodiment. Its basic structure is the same as that of the above embodiment. The pressing and clamping device is not shown in the figure. The difference is that only one milling cutter disc 6 is provided in this embodiment. The drilling and milling sliding power mechanism includes a lower sliding frame 9 longitudinally slidably connected to the machine frame 1 and driven by a lower power machine. A middle sliding frame 10 driven by a middle power machine to slide horizontally is connected to the lower sliding frame 9. An upper sliding frame 11 driven by an upper power machine to slide vertically is connected to the middle sliding frame 10. The drilling and milling table 2 is connected to the upper sliding frame 11. That is to say, in this embodiment, the lower sliding frame 9 slides longitudinally, the middle sliding frame 10 slides horizontally, and the upper sliding frame 11 slides vertically, finally realizing the three-axis positioning of the drilling and milling table and ensuring the processing accuracy.

[0047] Of course, the present invention is not limited to the above embodiments. For example, it is also possible to first achieve the vertical sliding of the lower sliding frame 9, then achieve the horizontal sliding of the middle sliding frame 10, and finally achieve the longitudinal sliding of the upper sliding frame 11, and so on. Such structures can also achieve the sliding of the drilling and milling table to move the drill bit fixture and the milling cutter head closer to and away from the profile channel. Similarly, the sawing table 3 is not limited to vertical sliding and horizontal sliding, and its purpose is only to achieve the sliding of the sawing table closer to and away from the profile channel. The specific left-right and up-down positions of the drilling and milling table 2 and the sawing table 3 relative to the profile channel are determined according to different types of profiles and corresponding installation requirements. In addition, the motion control of each of the above-mentioned sliding actions can be achieved through the conventional electrical control structure of those skilled in the art in combination with the above-mentioned action descriptions, and will not be elaborated in detail here.

[0048] Refer to Figure 2 , Figures 14 to 16As shown in the figure, the loading and feeding device includes a loading rack 30. On the loading rack 30, a plurality of longitudinally arranged and spaced loading and conveying brackets are installed. On the loading and conveying brackets, at least two laterally opposite loading and conveying wheels 31 are installed. A loading conveyor belt 32 is connected between the two laterally opposite loading and conveying wheels 31. On the loading conveyor belt 32, a plurality of conveying stoppers 33 are installed at intervals along its surface. A loading and conveying shaft 34 is installed through a plurality of longitudinally opposite loading and conveying wheels. The loading and conveying shaft is driven by a loading motor. That is to say, the conveying wheels on the adjacent two conveying brackets are on the same longitudinal straight line. The conveying stoppers 33 on the loading conveyor belts 32 on the adjacent two conveying brackets are longitudinally corresponding. A plurality of longitudinally opposite conveying stoppers 33 are on the same longitudinal straight line. The profiles are blocked by the conveying stoppers 33 and conveyed by the loading conveyor belt. A plurality of conveying wheels on the same longitudinal straight line are installed on the same loading and conveying shaft. In this embodiment, multiple loading conveyor belts 32 gradually become lower from front to back, which is beneficial to the conveying of profiles. A feeding rack 35 corresponding to the processing platform 10 is installed on the loading rack and longitudinally slides driven by a feeding motor. The sliding of the feeding rack 35 can adopt a structure driven by a servo motor. A longitudinal rack is provided on the loading rack. A gear is installed on the power output shaft of the servo motor. Through the meshing of the gear and the rack and the power drive of the servo motor, the sliding of the feeding rack is realized. The loading clamping device includes a clamping hand 36 connected to the feeding rack 35 and capable of clamping profiles. The rod-shaped object in the figure is the clamping hand. The clamping end of the clamping hand is two hinged clamping arms. By driving one clamping arm to act, the two clamping arms can clamp the profiles. Of course, a thumb cylinder structure can also be used as the clamping hand, and its structure will not be elaborated here. In this embodiment, a lower feeding sliding seat 39 driven by a clamping and feeding power machine to slide laterally is installed on the feeding rack 35. An upper feeding sliding seat 40 driven by a power machine to slide vertically is connected to the lower feeding sliding seat 39. The clamping hand is connected to the upper feeding sliding seat 40. Through the power drive of the clamping and feeding power machine and the power machine, the up-and-down position and left-and-right position of the clamping hand 36 are adjusted to facilitate accurate clamping of profiles. A straightening plate 37 driven by a pressing and straightening power machine to slide laterally is also installed on the loading rack 30. A plurality of retaining columns 38 are installed on the loading rack 30 longitudinally arranged and spaced. A freely rotatable retaining ring is connected to the retaining column. The straightening plate is located on one side of the retaining column and at the output end of the loading conveyor belt. When the straightening plate slides laterally, it can pull the profiles and make them lean against the retaining column. The loading conveyor belt 32 conveys the profiles towards the clamping hand. Before the profiles are conveyed to the clamping position and clamped, through the pressing and straightening action of the straightening plate, the profiles are further straightened to improve the accuracy of sawing and drilling. The above-mentioned straightening plate 37 and the pressing and straightening power machine can be installed on a lifting frame. The lifting frame is driven by a cylinder. After the lifting frame is raised, the above-mentioned pressing and straightening work is carried out. After completion, the lifting frame can be lowered. In order to further ensure the straightness of the profiles and the stability during end milling after the profiles are sawed off, in combination withFigures 20 to 22 As shown, a flow guiding and straightening device capable of guiding and straightening profiles when they enter is installed on the processing support table 18. The flow guiding and straightening device includes a translation roller 60 and a static roller 61 which are connected to the front part of the processing support table and arranged transversely opposite to each other. The profile channel passes through between the translation roller 60 and the static roller 61. A translation cylinder 62 capable of pushing the translation roller towards the static roller is connected to the processing support table 18. At the front part of the processing support table, an upper moving roller 63 and a lower static roller 64 which are arranged vertically opposite to each other are also installed. The profile channel passes through between the upper moving roller 63 and the lower static roller 64. A vertical moving cylinder 65 capable of pushing the upper moving roller 63 towards the lower static roller 64 is connected to the processing support table 18. The rear section of the profile after being cut by the saw can be clamped and pressed from above and below by the upper moving roller 63 and the lower static roller 64, and the rear section of the profile after being cut by the saw can be clamped and pressed from left and right by the translation roller 60 and the static roller 614, which not only ensures the straightness of the profile when it extends, but also prevents the profile from vibrating during the end milling process and ensures the processing accuracy.

[0049] Referring to Figure 2 、 Figures 17 to 19 As shown, the feeding and discharging device includes a discharging frame 50. A blanking sliding frame 41 corresponding to the processing platform 10 and longitudinally sliding driven by a discharging motor is installed on the discharging frame 50. The sliding of the blanking sliding frame 41 can adopt a structure driven by a servo motor. A longitudinal rack is provided on the discharging frame 50, and a gear is installed on the power output shaft of the servo motor. Through the meshing of the gear and the rack and the power drive of the servo motor, the sliding of the blanking sliding frame 41 is realized. A blanking gripper 42 capable of gripping the profile is installed on the blanking sliding frame 41. A plurality of discharging brackets 43 which are longitudinally arranged and spaced are also connected to the discharging frame 50. At least two discharging conveying wheels 44 which are arranged transversely opposite to each other are installed on the discharging brackets 43. A discharging conveyor belt 45 is connected between the two transversely opposite discharging conveying wheels 44. A discharging conveying shaft 46 is penetrated through a plurality of longitudinally opposite discharging conveying wheels 44, and the discharging conveying shaft is driven by the discharging motor. That is to say, the discharging conveying wheels on the adjacent two discharging brackets are on the same longitudinal straight line, and a plurality of discharging conveying wheels on the same longitudinal straight line are penetrated through the same discharging conveying shaft 46. In this embodiment, the plurality of discharging conveyor belts 45 gradually become lower from front to back, which is beneficial to the conveying of the profile. The discharging clamping device includes a discharging clamping support roller 51 connected to the discharging frame 50. A moving clamping block 52 corresponding to the discharging clamping bottom support is installed on the discharging frame 50. A discharging clamping cylinder 53 capable of driving the moving clamping block to slide downward so as to clamp the profile together with the discharging clamping support roller is connected to the discharging frame 50. Since the profile is relatively long, the above-mentioned discharging clamping support roller can support the profile, the above-mentioned moving clamping block presses the profile, and the discharging gripper 42 grips the profile. The three work together to ensure the stability of the end milling.

[0050] As shown in all the attached drawings, when the present invention is in use, the profile is conveyed on the loading conveyor belt 32 by the conveying stopper 33 and the loading conveyor belt 32. The pressing and straightening power machine drives the straightening plate 37 to slide horizontally, pulling the profile and making it lean against the stop post. Then, the clamping hand 36 precisely clamps the profile through the sliding of the lower feeding sliding seat 39 and the upper feeding sliding seat 40. After clamping the profile, the feeding rack 35 slides longitudinally for feeding. When the feeding reaches the appropriate position, the front end of the profile will extend into the feeding and unloading device, and the front section of the profile is clamped by the unloading clamping hand 42. During the feeding process, the upper moving roller 63, the lower static roller 64, the horizontal moving roller 60, and the horizontal static roller 61 cooperate with each other to clamp, press, and straighten the profile. The sawing sliding power mechanism slides the sawing table 3 close to the profile channel to saw the profile. After sawing, under the clamping action of the two sections of the profile respectively, the two sections of the profile are pulled apart by a certain distance. The milling sliding power mechanism slides the drilling and milling table to make the drill bit fixture and the milling cutter disc close to the profile channel. The milling cutter disc simultaneously mills the front and rear ends of the two sections of the profile and drills the profile. After drilling and end milling, under the sliding action of the unloading sliding frame 41, the completed door and window materials are transported backward, and finally, the unloading conveyor belt 45 transports the door and window materials out.

[0051] The present invention is not limited by the above embodiments. For those skilled in the art, equivalent changes and component replacements based on the specific structure of the present invention are within the protection scope of the present invention. In addition, the present invention can not only be used for sawing and drilling of door and window profiles, but also for other profiles.
