Description

Technical Field

[0001] The invention relates to the field of profile processing, and in particular to an angular position sawing and milling processing device and a processing method for a wood-like profile. Background Art

[0002] The imitation wood (HFL) right-angle welding process is mostly used at the corners of imitation wood profiles, which can achieve right-angle welding with imitation wood effect, so that plastic doors and windows can present the texture and grain of wood in appearance, improve the overall aesthetics of doors and windows, and make doors and windows more coordinated and unified with the home environment. In the specific operation, use cutting equipment to cut the plastic imitation wood profile into the required length and angle to prepare for right-angle welding. Place the cleaned profile on the workbench of the welding equipment, accurately position and fix the profile through the positioning device and clamp to ensure that the two ends of the profile to be welded form a right angle, start the welding equipment, and use the heating device to make the welding part of the profile reach a molten state. Under a certain pressure, the molten parts of the two profiles are fused to form a firm right-angle connection. In conventional cutting and welding methods, the welds are inclined relative to the door and window frames, and the welds at the welding positions are exposed on the outside, resulting in poor aesthetics of the plastic profile imitation wood doors and windows. The appearance of the connection positions of adjacent frames is quite different from the appearance of the mortise and tenon connection method of actual wooden doors and windows. The joints formed after the mortise and tenon connection of the wooden doors and windows are parallel to one of the frame rods.

[0003] A Chinese patent (publication number CN104453622A, publication date 20150325) discloses a corner connection structure of a plastic-steel window sash, wherein the connection of the first connection profile is a 45° bevel cutting structure, and a mortise groove is processed on one end face of the connection of the first connection profile, and the depth of the mortise groove is 5 to 10 mm; the connection of the second connection profile is a 45° bevel cutting structure, and the second connection profile is provided with a connecting tenon structure matched with the mortise groove, the first connection profile and the second connection profile are welded together at the 45° bevel cutting structure, and the first connection profile and the second connection profile on one side of the mortise groove form a 90° right-angle docking structure, thereby improving the imitation solid wood effect of the plastic-steel window surface. Since the connecting tenon and the mortise groove are in contact rather than directly connected, as the use time after installation increases, the thickness of the connecting tenon is small and the overall strength is insufficient, the end of the connecting tenon will deform and warp, resulting in the connecting tenon being unable to maintain fit with the mortise groove, which will not only greatly affect the appearance, but also lead to the deterioration of the shielding and protection effect of the mortise groove. Rainwater, dirt, etc. will penetrate into the interior of the profile along the mortise groove, accelerate its aging, and affect its durability. Summary of the invention

[0004] The purpose of the present invention is to provide a wood-like profile angular position sawing and milling processing device and processing method in view of the defects existing in the prior art, wherein a mortise and tenon groove is formed at the end of the profile through a milling component, and a limiting groove is formed on the side of the mortise and tenon groove, wherein the limiting groove can be clamped on the side of the connecting tenon, effectively restraining the connecting tenon from tilting, solving the deformation problem caused by insufficient strength of the connecting tenon, improving the aesthetics, maintaining a good fit between the mortise and tenon groove and the connecting tenon, ensuring the protection of the connecting tenon to the mortise and tenon groove, and reducing the erosion of the inside of the profile by external factors.

[0005] The first object of the present invention is to provide a wood-like profile angular position sawing and milling device, which adopts the following scheme: include: The clamping and conveying assembly comprises a conveying mechanism and two sets of clamping mechanisms distributed at intervals, and each set of clamping mechanisms is respectively matched with a conveying mechanism; The sawing assembly comprises a first mechanical arm and a sawing mechanism, wherein a saw blade at the end of the sawing mechanism changes its posture under the regulation of the first mechanical arm to saw the profiles between the two sets of clamping mechanisms and form a connecting tenon at the end of one profile; The milling assembly includes a second robotic arm and a milling mechanism. The milling cutter at the end of the milling mechanism changes its posture under the adjustment of the second robotic arm to mill the profiles carried by the two groups of clamping mechanisms, and form a mortise and tenon groove at the end of the other profile. The bottom surface of the mortise and tenon groove fits the connecting tenon, and the side surface of the mortise and tenon groove forms a limiting groove that clamps the side surface of the connecting tenon and constrains the connecting tenon from tilting.

[0006] Furthermore, the milling mechanism includes a first milling cutter and a second milling cutter that operate independently. The first milling cutter and the second milling cutter are located at different ends of the milling mechanism. The first milling cutter is used to form the mortise and tenon grooves and the limit grooves, and the second milling cutter is used to chamfer the ends of the connecting tenons.

[0007] Furthermore, a milling rotary mechanism is provided at the end of the second robot arm, and the milling rotary mechanism drives the milling mechanism to rotate to adjust the posture and switch the working state of the first milling cutter and the second milling cutter.

[0008] Furthermore, the first robotic arm and the second robotic arm are both multi-degree-of-freedom robotic arms. The first robotic arm drives the saw blade to adjust the three-axis position and the three-axis inclination angle, and the second robotic arm drives the milling cutter to adjust the three-axis position and the inclination angle.

[0009] Furthermore, a material receiving trough is provided below the clamping and conveying assembly, the top of the material receiving trough is open as an inlet end for receiving waste materials, and the outlet end of the material receiving trough is connected to a conveyor belt.

[0010] The second object of the present invention is to provide a method for processing a wood-like profile angular position sawing and milling processing device, using the wood-like profile angular position sawing and milling processing device as described in the first object, comprising: The conveying mechanism grabs the whole profile and feeds it to the clamping mechanism, and the sawing assembly adjusts the position of the saw blade between the two sets of clamping mechanisms to cut off the whole profile to obtain the first profile and the second profile; The sawing assembly adjusts the saw blade posture to cut the first profile and the second profile ends, forming a first beveled welding surface and a connecting tenon extending from the beveled welding surface at the first profile end, and forming a second beveled welding surface at the second profile end; The milling assembly adjusts the milling cutter posture, and mills the second profile to form a tenon groove on one side of the second beveled welding surface, the thickness of the tenon groove is adapted to the thickness of the connecting tenon, and a limiting groove is formed on the side of the tenon groove; Output the first profile and the second profile, align the first beveled welding surface and the second beveled welding surface, fit one side of the connecting tenon into the mortise groove, and insert the connecting tenon into the limiting groove on the side facing the limiting groove, so that the first profile and the second profile form a right-angle docking structure.

[0011] Furthermore, when cutting the first profile, the first profile is first cut parallel to the length direction to form a connecting tenon, and then cut parallel to the direction of the first beveled welding surface to remove the material head to form the first welding beveled surface.

[0012] Furthermore, before cutting the first profile, one end of the first profile forming the connecting tenon is milled and chamfered using a milling assembly.

[0013] Furthermore, the second profile is firstly cut to form a beveled welding surface, and then part of the material is removed by milling in a direction parallel to the bottom surface of the mortise and tenon groove to form the mortise and tenon groove and the limiting groove.

[0014] Furthermore, after the entire profile is cut, the relative positions of the first profile and the second profile are adjusted to form a space for the sawing assembly and the milling assembly to operate.

[0015] Compared with the prior art, the present invention has the following advantages and positive effects: In view of the problem that the connecting tenons and mortise grooves at the corners of the current imitation wood profiles are prone to deformation and warping, which leads to reduced aesthetics and protection, a mortise groove is formed at the end of the profile through a milling component, and a limiting groove is formed on the side of the mortise groove, wherein the limiting groove can clamp the side of the connecting tenon, effectively restraining the connecting tenon from warping, solving the deformation problem caused by insufficient strength of the connecting tenon, improving aesthetics, maintaining a good fit between the mortise groove and the connecting tenon, ensuring the protection of the mortise groove by the connecting tenon, and reducing the erosion of the inside of the profile by external factors.

[0016] The multi-degree-of-freedom robot arm is used to accurately adjust the posture of the saw blade and the milling cutter, so that the sawing component can use a single saw blade to adjust the posture to establish multiple processing methods to meet the diverse sawing needs such as cutting and corner cutting. Similarly, by adjusting the milling cutter posture, the milling cutter completes the corresponding chamfering, milling to form the tenon groove and limit groove, so that the processed structural dimensions of the tenon, tenon groove and limit groove are accurate, which improves the processing quality of the corner position of the imitation wood profile and ensures the reliability of the profile connection. The setting of the receiving trough and conveyor belt realizes the automatic collection and transportation of waste materials, keeps the working area clean and tidy, and is conducive to safe production and equipment maintenance.

[0017] When cutting the first profile, a step-by-step cutting method is adopted. First, the first profile is cut parallel to the length direction to form a connecting tenon, which is equivalent to creating a stress release point on the profile, so that the stress inside the profile is initially dispersed in this process. Then, the first beveled welding surface is cut parallel to the direction of the first beveled welding surface, and the material head is removed to form the first welding beveled surface. By releasing part of the stress first and then performing subsequent cutting, the excessive concentration of stress in a certain area is effectively avoided, the connecting tenon of the cantilever structure is protected, and the deformation and cracking of the profile caused by stress concentration are reduced, thereby improving the mechanical properties and service life of the profile.

DETAILED DESCRIPTION

[0026] Example 1 In a typical embodiment of the present invention, Figure 1-Figure 6 As shown, a device for sawing and milling the angular position of imitation wood profiles is provided.

[0027] In the prior art, the thickness of the connecting tenon 11 is small and the overall strength is poor. After long-term use, the end is prone to deformation and warping. Since the connecting tenon 11 and the tenon groove 7 are in close contact rather than welded, if the connecting tenon 11 is thickened, the welding range of the profile angle position will be reduced, resulting in reduced welding strength. After the connecting tenon 11 is deformed and warped, the poor fit leads to poor protection of the tenon groove 7, and rainwater and dirt easily invade the interior of the profile to accelerate aging. Based on this, the present embodiment provides a wood-like profile angle position sawing and milling device, which forms a tenon groove 7 with a limiting groove 8 at the end of the profile through a milling component, and the limiting groove 8 is located on the side of the tenon groove 7. The limiting groove 8 is used to clamp the side 6 of the connecting tenon. The side 6 of the connecting tenon is used as a limiting block, and cooperates with the tenon groove 7 to form a clamping constraint, which effectively limits the connection tenon 11 from tilting, solves the deformation problem caused by insufficient strength of the connecting tenon 11, and ensures the stability of the connection structure.

[0028] In the past, the connecting tenon 11 and the tenon groove 7 were in contact but not directly connected and fixed by welding, bonding, etc., but kept in close contact, and the constraint between the two was not tight enough. When there are external environmental factors such as temperature changes and humidity fluctuations, the plastic profile will produce thermal expansion and contraction. Due to the lack of tight and effective constraints between the connecting tenon 11 and the tenon groove 7, the connecting tenon 11 is prone to displacement and deformation during the thermal expansion and contraction process. As time goes by, the accumulated deformation manifests as warping. Moreover, in actual use, after the profile is used to make doors and windows, the doors and windows may be subjected to various unexpected external impacts, such as strong winds, collisions, etc. The connecting tenon 11 without tight constraints is also more likely to warp under the action of these external forces. The warped connecting tenon 11 loses its fit to the tenon groove 7, resulting in poor protection of the tenon groove 7, and rainwater and dirt easily invade the interior of the profile to accelerate aging.

[0029] like Figure 1-Figure 4As shown, the sawing and milling device for the corner position of the imitation wood profile makes the bottom surface 10 of the mortise groove fit the connecting tenon 11 to enhance the fit. At the same time, the limiting groove 8 structure can clamp one side of the connecting tenon 11. Even if the connecting tenon 11 tends to warp due to prolonged use, the limiting groove 8 can restrain the connecting tenon 11 to prevent the connecting tenon 11 from detaching from the mortise groove 7, thereby ensuring the stability of the connection, strengthening the protection of the mortise groove 7, and reducing the erosion of the internal part of the profile by external factors.

[0030] Specifically, Figure 5 As shown, the angular position sawing and milling processing device for imitation wood profiles includes a clamping and conveying component 12, a sawing component and a milling component.

[0031] The clamping and conveying assembly 12 is composed of a conveying mechanism and two groups of clamping mechanisms distributed at intervals, and each group of clamping mechanisms cooperates with the conveying mechanism. The clamping and conveying assembly 12 can stably convey and fix the profile, providing a reliable basis for subsequent sawing and milling processing. The conveying mechanism is responsible for accurately conveying the profile to the specified position, and the clamping mechanism firmly clamps the profile to prevent displacement during the processing and ensure processing accuracy.

[0032] In this embodiment, the clamping and conveying assembly 12 can be formed by combining an existing clamping mechanism and a conveying mechanism. The conveying mechanism can adopt a roller conveyor belt 18, which is driven by a motor and realizes stable operation of the conveyor belt 18 through gear transmission. The surface of the conveyor belt 18 is made of rubber material, which increases the friction between the conveyor belt and the profile to ensure that the profile does not slip during the conveying process. Adjustable guide baffles are provided on both sides of the conveyor belt 18, which can be adjusted according to the width of different profiles to ensure that the profile is always accurately conveyed to the specified position along the predetermined path. In other optional embodiments, the conveying mechanism can also adopt an electric cylinder, a pneumatic cylinder, etc. in conjunction with a mechanical claw to clamp the profile. After the mechanical claw clamps the profile, it is driven by a linear drive component such as an electric cylinder or a pneumatic cylinder to move and adjust the position to meet the needs of sawing and milling.

[0033] As for the clamping mechanism, each clamping mechanism consists of two movable clamping arms, which are pneumatically controlled. An elastic rubber pad is installed on the inside of the clamping arm, which can increase the friction with the profile to prevent the profile from sliding during clamping and avoid clamping the profile surface. The clamping arm is connected to the mounting base through a slide rail and can be adjusted up and down according to the height of the profile. When clamping the profile, the clamping arm is driven inward by air pressure to tightly clamp the profile; when the profile needs to be released after processing, the air pressure drives the clamping arm to open outward in the opposite direction. Maintain the stability of the profile during sawing and milling.

[0034] When the entire profile is placed on the conveyor belt 18, the conveying mechanism starts to work and conveys the profile to the predetermined position between the two sets of clamping mechanisms. After reaching the position, the conveying mechanism pauses, and the clamping arms of the two sets of clamping mechanisms move simultaneously to tightly clamp the profile. At this time, the sawing assembly and the milling assembly can perform corresponding processing operations on the profile. During the processing, the clamping mechanism always maintains a firm grip on the profile to prevent it from moving and ensure processing accuracy. After the processing is completed, the clamping mechanism releases the profile, and the conveying mechanism starts again to convey the processed profile to the next process.

[0035] like Figure 6 As shown, the sawing assembly includes a first mechanical arm 13 and a sawing mechanism 14. The saw blade 19 at the end of the sawing mechanism 14 changes its posture under the adjustment of the first mechanical arm 13. Driven by the first mechanical arm 13, the profile located between the two sets of clamping mechanisms can be sawed flexibly. On the one hand, the entire profile can be cut off, and on the other hand, a connecting tenon 11 can be formed at the end of a profile, and the beveled surface for welding can also be sawed. Through the precise adjustment of the mechanical arm, the sawing accuracy and the dimensional accuracy of the connecting tenon 11 can be guaranteed.

[0036] Specifically, the first robot arm 13 can be a six-axis industrial robot arm with high degree of freedom and high precision. Its joints are driven by servo motors and equipped with high-precision reducers to achieve precise angle control and position positioning. The base of the first robot arm 13 is fixed on a movable slide, which is connected to the frame of the processing equipment through a linear guide rail. The servo motor drives the ball screw to move forward and backward, expanding the working range of the first robot arm 13. The arm span of the first robot arm 13 is designed according to the processing requirements, so that it can cover the profile processing area between the two sets of clamping mechanisms.

[0037] It is understandable that in other optional embodiments, a combination of multiple sets of lead screw slider mechanisms and swing electric cylinders can be used to establish the first mechanical arm 13. Multiple sets of lead screw slider mechanisms are used to form a multi-axis mechanical arm, and multiple swing electric cylinders are connected in series to form the required posture adjustment mechanism.

[0038] The sawing mechanism 14 is installed at the end of the first mechanical arm 13, and is mainly composed of a saw blade 19, a saw blade 19 motor and a saw blade 19 mounting seat. The saw blade 19 is made of cemented carbide, has high hardness and wear resistance, and its diameter is selected according to the profile to be sawed, such as 300 mm, etc., which is suitable for sawing various plastic imitation wood profiles. The saw blade 19 motor is a high-speed variable frequency motor, and the speed can be adjusted according to the material and thickness of the profile. The maximum speed is also selected according to demand, and a saw blade 19 motor with a maximum speed of 5000 rpm can be used. The saw blade 19 mounting seat is connected to the end of the first mechanical arm 13 through a rotatable joint, which is driven by a motor and can realize the angle adjustment of the saw blade 19 within a range of 360° to meet the sawing needs of different angles.

[0039] The first robot arm 13 and the sawing mechanism 14 are equipped with corresponding numerical control systems, and the motion trajectory and sawing parameters of the robot arm are set by programming. The operator can input parameters such as sawing length, angle, cutting speed, etc. on the control panel, and the numerical control system accurately controls the movement of the robot arm and the sawing mechanism 14 according to these parameters. During the sawing process, the robot arm moves according to the preset trajectory, accurately positions the saw blade 19 to the sawing position of the profile, and adjusts the angle and sawing speed of the saw blade 19 as needed. For example, when cutting off the entire profile, the robot arm cuts the saw blade 19 vertically downward; when forming the connecting tenon 11, the robot arm adjusts the angle and motion trajectory of the saw blade 19 according to the design requirements to ensure the dimensional accuracy and shape accuracy of the connecting tenon 11.

[0040] like Figure 6 As shown, the milling assembly is composed of a second mechanical arm 15 and a milling mechanism 16, and the milling cutter 20 at the end of the milling mechanism 16 changes its posture under the adjustment of the second mechanical arm 15. The milling assembly is mainly used to form a tenon groove 7 and a limit groove 8 at the end of another profile. The multi-degree-of-freedom adjustment function of the second mechanical arm 15 enables the milling cutter 20 to perform milling accurately according to the design requirements, ensuring that the bottom surface 10 of the tenon groove fits the connecting tenon 11, and at the same time accurately forming the limit groove 8 on the side of the tenon groove 7 to achieve effective constraint on the connecting tenon 11.

[0041] Specifically, the second robot arm 15 can also use a six-axis industrial robot arm, and each joint is driven by a high-performance servo motor, which cooperates with a high-precision planetary reducer to achieve extremely precise angle control and position positioning. The base of the second robot arm 15 is fixed on a lifting platform that can move up and down along the guide rail. The lifting platform is connected to the main frame of the processing equipment through a high-precision linear guide rail. The servo motor drives the ball screw to complete the lifting action, which greatly expands the working range of the robot arm in the vertical direction. The maximum extension length of the second robot arm 15 is selected according to demand, which is sufficient to flexibly cover the profile processing area between the two sets of clamping mechanisms, ensuring that profiles in different positions can be milled.

[0042] The milling mechanism 16 is installed at the end of the second mechanical arm 15, and is mainly composed of a milling cutter 20, a milling cutter motor and a milling cutter mounting seat. The milling cutter 20 is made of super-hard alloy, and its hardness and wear resistance can meet the requirements of profile processing. The diameter and shape of the milling cutter 20 can be designed according to the requirements. For example, a milling cutter 20 with a cross-sectional shape that matches the limit groove 8 can meet the complex milling requirements of various imitation wood profiles. The milling cutter motor adopts a high-frequency high-speed motor, and the speed can be accurately adjusted through a frequency conversion controller according to the material characteristics and processing requirements of the profile. The milling cutter mounting seat is connected to the end of the second mechanical arm 15 through a rotary joint with a 360° rotation function as a milling rotary mechanism. The rotary joint is driven by an independent servo motor, which can realize the precise adjustment of the milling cutter 20 at any angle, fully meeting the milling requirements of the mortise and tenon grooves 7 and limit grooves 8 of different angles and shapes.

[0043] like Figure 5 and Figure 6 As shown, the milling mechanism 16 adopts a double milling cutter design, with clear division of labor to improve efficiency. The milling mechanism 16 includes a first milling cutter and a second milling cutter that operate independently and are located at different ends of the milling mechanism 16. The first milling cutter is responsible for forming the mortise and tenon groove 7 and the limit groove 8, which are key structures for forming the corner position connection of the imitation wood profile; the second milling cutter is used to chamfer the end 3 of the connecting tenon 4. The chamfering 4 treatment can not only optimize the appearance of the connecting tenon 11, but also avoid safety hazards and component damage caused by sharp corners during subsequent installation and use. The double milling cutters 20 operate independently and can perform processing of different processes at the same time, which greatly improves the processing efficiency and shortens the overall processing time.

[0044] Different processing tasks are handled by a dedicated milling cutter 20, avoiding the precision error that may be caused by frequent replacement of processing tasks by a single milling cutter 20. When forming the tenon groove 7 and the limit groove 8, the first milling cutter can perform precise milling according to preset parameters to ensure the dimensional accuracy of the tenon groove 7 and the position accuracy of the limit groove 8, thereby ensuring good cooperation with the connecting tenon 11.

[0045] like Figure 5 and Figure 6 As shown, the milling rotary mechanism at the end of the second mechanical arm 15 can drive the milling mechanism 16 to rotate, which can not only adjust the posture of the milling cutter 20, but also switch the working state of the first milling cutter and the second milling cutter, so that at the same processing position, the processing process can be quickly switched without replacing the entire milling mechanism 16. After the milling of the tenon groove 7 and the limit groove 8 is completed, the second milling cutter can be quickly switched to the working position through the milling rotary mechanism, and the end of the connecting tenon 11 can be chamfered 4, which improves the continuity of processing and the efficiency of equipment use.

[0046] The milling assembly is equipped with a set of numerical control systems, and professional programming software is used to set the motion trajectory of the robot arm and the milling process parameters. The operator can conveniently input the size, depth, angle and other processing parameters of the mortise and tenon groove 7 and the limit groove 8 on the operation panel, and the numerical control system will accurately calculate and control every movement of the robot arm and the milling mechanism 16 based on these parameters. During the milling process, the robot arm moves strictly according to the preset trajectory, accurately positions the milling cutter 20 to the milling part of the profile, and adjusts the angle and milling speed of the milling cutter 20 in real time according to the processing requirements. When milling the mortise and tenon groove 7, the robot arm drives the milling cutter 20 to cut steadily according to the predetermined depth and width; when processing the limit groove 8, the robot arm accurately adjusts the angle and motion path of the milling cutter 20 according to the design requirements to ensure that the size accuracy and shape of the limit groove 8 meet the design standards, thereby achieving effective constraints on the connecting tenon 11.

[0047] The first mechanical arm 13 and the second mechanical arm 15 are both multi-degree-of-freedom mechanical arms, which can drive the saw blade 19 and the milling cutter 20 to adjust the three-axis position and the three-axis inclination angle, giving the processing device extremely high flexibility and precision. During the sawing process, the first mechanical arm 13 can accurately adjust the position and angle of the saw blade 19 according to the shape, size and processing requirements of the profile, to ensure that the cut connecting tenon 11 is accurate in size and meets the design requirements in shape. Similarly, when the second mechanical arm 15 drives the milling cutter 20 for milling, it can also achieve high-precision processing of the tenon groove 7 and the limit groove 8 through multi-degree-of-freedom adjustment to meet the complex processing requirements of different imitation wood profiles. The application of multi-degree-of-freedom mechanical arms enables the processing device to adapt to the processing of imitation wood profiles of different specifications and shapes. Whether it is a profile of conventional size or a special-shaped profile with special design requirements, the processing task can be completed through the flexible adjustment of the mechanical arm, which greatly expands the scope of application of the device.

[0048] Through the processing of the imitation wood profile by the sawing and milling device at the corner position of the imitation wood profile, the clamping constraint of the limit groove 8 on the side 6 of the connecting tenon significantly enhances the stability of the connection between the connecting tenon 11 and the tenon groove 7, improves the connection strength at the corner position of the imitation wood profile, makes the entire profile structure more solid, and prolongs the service life. It ensures the good fit between the connecting tenon 11 and the tenon groove 7, avoids the appearance defects caused by the deformation and warping of the connecting tenon 11, further enhances the imitation wood effect of the imitation wood profile, meets the consumer's pursuit of aesthetics, and the optimized connection structure effectively blocks rainwater, dirt, etc. from invading the interior of the profile, slows down the aging speed of the profile, improves durability, and reduces the later maintenance cost.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the side surface 6 of the connecting tenon refers to one side along the length direction of the profile where the connecting tenon 11 is located, and the end 3 of the connecting tenon refers to one end along the length direction of the profile where the connecting tenon 11 is located. The bottom surface 10 of the mortise groove is the bottom surface of the groove recessed in the profile surface formed after the profile is milled by the milling assembly. The side surface of the mortise groove 7 refers to the side away from the end along the length direction of the profile where it is located, and is also the side surface of the groove. The limiting groove 8 is a groove distributed on the side surface of the mortise groove 7, which is recessed relative to the side surface of the mortise groove 7. The cross-sectional shape of the limiting groove 8 is adapted to the cross-sectional shape of the side surface 6 of the connecting tenon to achieve a snap-on connection. The snap-on connection with the side surface of the connecting tenon 11 is achieved through this adaptation relationship, thereby effectively restraining the connecting tenon 11 and preventing it from tilting, thereby ensuring the stability and reliability of the corner position connection of the imitation wood profile.

[0050] The operation switching of different milling cutters 20 is achieved by the rotation of the milling rotary mechanism, thereby avoiding the space occupation problem that may be caused by setting up multiple independent milling mechanisms 16, making the structure of the entire processing device more concise and efficient.

[0051] like Figure 5 and Figure 6 As shown, a receiving trough 17 is provided below the clamping and conveying assembly 12, with the top open as the inlet end for receiving waste materials, and the outlet end docking with the conveyor belt 18. Waste materials generated during sawing and milling processing, such as plastic scraps, metal scraps, material heads, etc., can directly fall into the receiving trough 17, and then be transported to a designated location for centralized processing through the conveyor belt 18, thereby realizing the automatic collection and transportation of waste materials, avoiding the accumulation of waste materials in the processing area, keeping the working environment clean, and also reducing the workload of manual waste cleaning, thereby improving production efficiency. Timely cleaning of waste materials can prevent waste materials from entering key parts of processing equipment, such as the joints of the robot arm, the transmission parts of the saw blade 19 and the milling cutter 20, thereby avoiding equipment failures caused by waste accumulation, extending the service life of the equipment, and ensuring the continuity and stability of the processing process.

[0052] Example 2 In another typical embodiment of the present invention, Figure 1-Figure 6 As shown, a processing method of an angular position sawing and milling processing device for imitation wood profiles is provided, using the angular position sawing and milling processing device for imitation wood profiles as in Example 1.

[0053] A processing method of a wood-like profile angular position sawing and milling processing device, comprising: The conveying mechanism grabs the whole profile and feeds it to the clamping mechanism. The sawing assembly adjusts the position of the saw blade 19 between the two sets of clamping mechanisms to cut off the whole profile to obtain the first profile 1 and the second profile 2. The sawing assembly adjusts the posture of the saw blade 19 to cut the ends of the first profile 1 and the second profile 2, forming a first beveled welding surface 5 and a connecting tenon 11 extending from the beveled welding surface at the end of the first profile 1, and forming a second beveled welding surface 9 at the end of the second profile 2; The milling assembly adjusts the posture of the milling cutter 20, and mills the second profile 2 to form a mortise groove 7 on one side of the second beveled welding surface 9, the thickness of the mortise groove 7 is adapted to the thickness of the connecting tenon 11, and a limiting groove 8 is formed on the side of the mortise groove 7; Output the first profile 1 and the second profile 2, align the first beveled welding surface 5 and the second beveled welding surface 9, fit one side of the connecting tenon 11 into the mortise groove 7, and insert the connecting tenon 11 into the limiting groove 8 on the side facing the limiting groove 8, so that the first profile 1 and the second profile 2 form a right-angle docking structure.

[0054] Different from the existing single-machine processing mode, the profile can only be cut first, and then the cut small sections are loaded and clamped, and then sawing and milling operations are carried out in sequence. The existing single-machine method has many disadvantages: on the one hand, multiple loading and clamping not only consumes a lot of time, but also each loading may introduce positioning errors, making it difficult to ensure processing accuracy; on the other hand, frequent manual operations or equipment switching actions increase the complexity of operations and the probability of errors, reducing overall production efficiency.

[0055] In this regard, Figure 5 and Figure 6 As shown, in the processing method of the wood-like profile angle sawing and milling processing device provided in this embodiment, the whole profile material can be directly processed. First, the conveying mechanism accurately grabs the whole profile and sends it to the clamping mechanism to ensure the stability of the profile position. Then the sawing component cuts the profile between the two sets of clamping mechanisms to obtain two profiles to be processed, which provides a basic unit for subsequent processing, and the orderly loading and cutting ensures the initial accuracy of the processing, avoids the error caused by multiple loading, and ensures the stability of the profile position.

[0056] The sawing assembly continues to adjust the posture of the saw blade 19, forming a connecting tenon 11 and a first beveled welding surface 5 at the end of the first profile 1, and a second beveled welding surface 9 at the end of the second profile 2. Then the milling assembly processes the second profile 2, forming a tenon groove 7 and a limit groove 8 on one side of the second beveled welding surface 9. The step-by-step processing method allows each processing step to focus on the forming of a specific structure, and since there is no need to frequently replace profiles and adjust equipment positioning, the processing process is more coherent, and each component can operate stably according to the preset program, improving the processing accuracy of key structures such as the connecting tenon 11, beveled welding surface, tenon groove 7 and limit groove 8.

[0057] Finally, the beveled welding surfaces of the first profile 1 and the second profile 2 are assembled at an angle so that the connecting tenon 11 cooperates with the mortise groove 7, and the connecting tenon 11 is inserted into the limiting groove 8 to form a stable right-angle docking structure, completing the final assembly link of the entire processing flow and ensuring the stability of the corner connection of the imitation wood profile.

[0058] By accurately adjusting the posture of the saw blade 19 and the milling cutter 20 through each component, the dimensional accuracy of the connecting tenon 11, the tenon groove 7 and the limiting groove 8 is ensured, which solves the problems of large dimensional deviation and loose connection of the connection structure in traditional processing, and makes the thickness of the connecting tenon 11 and the tenon groove 7 compatible, thereby improving the connection strength. The design and processing of the limiting groove 8 effectively solves the problem of unstable connection caused by the easy warping of the connecting tenon 11. By inserting the connecting tenon 11 into the limiting groove 8, the displacement of the connecting tenon 11 is limited, and the stability of the connection at the angle of the profile is enhanced. Clear processing steps and the coordinated work of each component avoid confusion and repeated operations during the processing, improve processing efficiency, and reduce processing time and labor costs compared to traditional processing methods.

[0059] Before cutting the first profile 1 to form the connecting tenon 11, the end is milled and chamfered 4 by a milling assembly. At this time, the first profile 1 has not yet formed the connecting tenon 11, and the overall stability is good when the chamfer 4 is processed. The chamfer 4 process can not only avoid the sharp corners at the end of the connecting tenon 11 causing safety hazards in subsequent processing and use, but also make the connection tenon 11 and the tenon groove 7 fit more closely during connection. By accurately controlling the parameters of the milling assembly, it can be ensured that the size and angle of the chamfer 4 meet the design requirements, further improving the accuracy and quality of the connection part.

[0060] Figure 1 , Figure 3 The structure of the end of the first profile 1 and the second profile 2 is shown. When cutting the first profile 1, first cut parallel to its length direction to form the connecting tenon 11, and the complete length of the profile can be used as a reference to ensure the length accuracy of the connecting tenon 11. The side 6 of the connecting tenon naturally forms a limit block that can cooperate with the limit groove 8. Then cut parallel to the direction of the first beveled welding surface 5 to remove the material head to form a welding bevel surface. The order of the two cuttings ensures that the dimensions of the connecting tenon 11 and the welding bevel surface can be accurately controlled, avoiding dimensional deviations caused by one-time cutting, improving the processing accuracy of the profile end structure, and providing a better foundation for the subsequent connection with the second profile 2.

[0061] Among them, the operation sequence of cutting the end of the first profile 1 is configured, first cutting parallel to the length direction of the first profile 1 to form a connecting tenon 11, which is equivalent to creating a stress release point on the profile, so that the stress inside the profile is initially dispersed in this process. Then cutting is parallel to the direction of the first beveled welding surface 5 formed, and the material head is removed to form the first welding beveled surface. By releasing part of the stress first and then performing subsequent cutting, it is effectively avoided that the stress is excessively concentrated in a certain area, and the connecting tenon 11 of the cantilever structure is protected, reducing the deformation and cracking of the profile caused by stress concentration, and improving the mechanical properties and service life of the profile.

[0062] The second profile 2 is first cut to form a beveled welding surface, and then part of the material is removed by milling in a direction parallel to the bottom surface 10 of the tenon groove to form the tenon groove 7 and the limit groove 8. The layered milling method makes the processing process more refined, and can better control the depth and width of the tenon groove 7 and the position and size accuracy of the limit groove 8, ensuring perfect fit with the connection tenon 11 of the first profile 1, and improving the accuracy and stability of the corner position connection of the imitation wood profile.

[0063] After cutting the entire profile, the relative positions of the first profile 1 and the second profile 2 are adjusted to form space for the sawing component and the milling component to operate. The processing space is planned in advance so that the sawing component and the milling component can be quickly put in place and start working, avoiding equipment adjustment and waiting time caused by improper profile positioning, thereby improving overall processing efficiency.

[0064] The milling process of the second profile 2 accurately forms the mortise and tenon groove 7 and the limit groove 8. The tightly fitting structure enables the connecting tenon 11 to be effectively constrained by the limit groove 8 when subjected to external force, thereby preventing the connecting tenon 11 from warping or displacement, thereby greatly improving the stability of the angular position connection of the imitation wood profile and ensuring that the entire profile structure remains firm during long-term use.

[0065] For the assembly structure of the connecting tenon 11 and the tenon groove 7 of the first profile 1, as shown in Figure 1 , Figure 4 As shown, the processed first profile 1 and the second profile 2 are angled, the first beveled welding surface 5 and the second beveled welding surface 9 are aligned close to each other so that they are in a state to be connected, and the first beveled welding surface 5 and the second beveled welding surface 9 are heated to angle them; in the process of angled, the connecting tenon 11 on the first profile 1 is inserted into the tenon groove 7 of the second profile 2, ensuring that one side of the connecting tenon 11 is tightly fitted to the bottom surface 10 of the tenon groove, so as to achieve preliminary connection positioning; then, the connecting tenon 11 is accurately inserted into the limiting groove 8 on the side facing the limiting groove 8, and the limiting groove 8 is used to constrain the side of the connecting tenon 11 to effectively prevent the connecting tenon 11 from warping or displacement during use, thereby further enhancing the stability of the connection. The assembled first profile 1 and the second profile 2 are as shown in FIG. Figure 4 shown.
