Description

Technical Field

[0001] This application relates to the field of profile processing technology, and more specifically, to a door and window profile processing equipment. Background Technology

[0002] Traditional door and window profile processing equipment typically employs a modular, independent design to achieve multi-face milling, sawing, and clamping functions. For example, it uses a multi-slide structure to achieve tool tilting machining, but the separate drive of cylinders and motors leads to space redundancy. The CN220196867U uses a four-axis gantry to improve processing efficiency, but the parallel structure of the dual slides increases costs. Furthermore, existing equipment is expensive overall and lacks coordination. Therefore, there is an urgent need for a highly integrated, multi-module co-driven, low-cost processing equipment to effectively improve the processing accuracy and stability of the sawing zone in profile processing equipment. Utility Model Content

[0003] This application proposes a door and window profile processing equipment that improves processing efficiency and quality, and also helps to reduce the overall complexity and manufacturing cost of the equipment.

[0004] In the first aspect, this application provides a door and window profile processing equipment, the technical solution of which is as follows:

[0005] It includes a feeding area, a sawing area, and an unloading area. The profile workpiece is sent from the feeding area to the sawing area for processing and then sent to the unloading area for unloading.

[0006] The sawing zone is equipped with a four-sided drilling and milling structure, which is used to perform drilling and milling on profile workpieces in different directions. The four-sided drilling and milling structure moves along the conveying direction of the profile workpiece.

[0007] This application provides a door and window profile processing equipment that overcomes the problems of low equipment integration, poor coordination, and insufficient processing accuracy and stability in the prior art through structural integration and optimized clamping methods. The four-sided drilling and milling structure is used to drill and mill different sides of the profile workpiece, increasing the processing flexibility.

[0008] Furthermore, this application also proposes that the four-sided drilling and milling structure includes a frame, with slide rails provided at the bottom of the frame and on both sides of the profile workpiece conveying channel, and a square mounting bracket provided on the slide rail so that the mounting bracket can slide along the slide rail, and machining tools that can move independently along the Y-axis and Z-axis are provided on the four directions of up, down, left and right of the mounting bracket.

[0009] The door and window profile processing equipment provided in this application has processing tools that can move independently along the Y and Z axes in four directions of the mounting frame, which enables the four-sided drilling and milling structure to perform multi-directional, multi-position, and high-precision drilling and milling on profile workpieces, providing greater processing flexibility and adaptability.

[0010] Furthermore, this application also proposes that the mounting frame is provided with a through hole for the profile workpiece to pass through, and the bottom of the frame is provided with a lifting structure so that an operating space is formed between the bottom of the mounting frame and the ground to accommodate the movement of the processing tool on the underside of the mounting frame.

[0011] The door and window profile processing equipment provided in this application ensures that the lower cutting tool can process the bottom of the profile normally and effectively, realize the processing of the profile workpiece on all four sides, and improve the processing capacity and practicality of the equipment.

[0012] Furthermore, this application also proposes a follower clamp disposed on a mounting frame, the follower clamp including a clamping mechanism disposed within the mounting frame, the clamping mechanism including a mounting part and a clamping part, the mounting part being disposed on the mounting frame.

[0013] This application provides a door and window profile processing equipment, which is equipped with a follow-up fixture that moves together with the four-sided drilling and milling structure, so that the clamping point is always close to the working position of the processing tool. This close-range clamping can more effectively suppress the vibration and deformation of the profile during processing, especially when drilling and milling the side or bottom, it can provide more reliable support. The application of the follow-up fixture significantly improves the local stability and accuracy of the drilling and milling process.

[0014] Furthermore, this application also proposes an auxiliary follower fixture connected to the mounting bracket. The clamping mechanism and the clamping part of the auxiliary follower fixture are located on both sides of the machining tool in the X-axis direction. When the machining tool processes the profile workpiece, the clamping mechanism and the auxiliary follower fixture position and circumferentially clamp the profile workpiece.

[0015] This application provides a door and window profile processing equipment that, by adding an auxiliary follow-up fixture and having it work in conjunction with the clamping mechanism, positions and circumferentially clamps the profile workpiece on both sides of the working area of ​​the processing tool. This double-sided, circumferential clamping method can more effectively resist the complex stress generated during drilling and milling, and prevent the profile workpiece from deforming or displacing.

[0016] Furthermore, this application also proposes that the machining tool includes a tool moving plate, a tilting cylinder disposed on the tool moving plate, and a turntable rotatably connected to the tool moving plate. The telescopic rod of the tilting cylinder is connected to the turntable to drive the turntable to rotate. It also includes a drilling and milling cutter disposed on the turntable and a first limiting cylinder. The first limiting cylinder is installed on one side of the drilling and milling cutter. When the turntable and the drilling and milling cutter tilt and machine in a retracted manner on the tilting cylinder, the first limiting cylinder is in a retracted state; or, when the turntable and the drilling and milling cutter tilt and machine in an extended manner on the tilting cylinder, the first limiting cylinder is in an extended state, in order to resist the return tendency of the drilling and milling cutter during the milling process.

[0017] The drilling and milling cutter of the door and window profile processing equipment provided in this application has the ability to perform angular machining, which significantly improves the processing flexibility and functional versatility of the equipment. At the same time, by setting a first limit cylinder, the return tendency generated during the milling process is effectively resisted, enhancing the rigidity and stability of the cutter, thereby improving the accuracy of milling and the service life of the cutter.

[0018] Furthermore, this application also proposes a sawing device that includes at least one 90-degree saw blade for sawing the profile workpiece to a set length. The 90-degree saw blade cuts along the Y-axis direction, which is perpendicular to the conveying direction of the profile workpiece.

[0019] Furthermore, this application also proposes a telescopic support fixture, which includes a Z-axis clamping module disposed on the side of a 90-degree saw blade for clamping the profile workpiece when the 90-degree saw blade cuts it; it also includes a Y-axis drive module connected to the Z-axis clamping module for driving the Z-axis clamping module to extend and retract in the Y-axis direction.

[0020] This application provides a door and window profile processing equipment that can provide additional vertical clamping support at the critical moment when the profile is about to be cut, effectively preventing workpiece shaking and cross-sectional cracking, and greatly improving the stability of the sawing process and the accuracy of the cross-section.

[0021] Furthermore, this application also proposes a pressing clamp disposed between the feeding area and the sawing area. The pressing clamp includes a pressing holding part, which can be raised and lowered along the Z-axis and rotated around the Z-axis. When the profile workpiece is processed, the pressing holding part fixes the profile workpiece from the Z-axis direction.

[0022] The door and window profile processing equipment provided in this application can perform initial positioning and fixation when the profile enters the processing area, and can also serve as an auxiliary support during the processing to enhance the overall clamping stability.

[0023] Furthermore, this application also proposes that the pressing clamp further includes a lifting mechanism for driving the pressing clamping part to move up and down along the Z-axis and a rotating mechanism for driving the pressing clamping part to rotate around the Z-axis; the lifting mechanism is connected to the rotating mechanism through a rotary joint, and the rotating mechanism is connected to the pressing clamping part.

[0024] Beneficial Effects: The door and window profile processing equipment provided in this application achieves an automated continuous processing flow for profile workpieces by setting up a feeding area, a sawing area, and an unloading area, solving the problem of poor equipment coordination in existing technologies. In particular, the four-sided drilling and milling structure set in the sawing area allows the profile workpiece to complete multi-directional drilling and milling processing in the same area, greatly improving the integration of the equipment and overcoming the structural dispersion problem caused by modular independent design in existing technologies. This ensures the stability and accuracy of the processing process and effectively solves the problem that the processing accuracy and stability of existing technologies need to be improved. This highly integrated, multi-module co-driven design not only improves processing efficiency and quality but also helps to reduce the overall complexity and manufacturing cost of the equipment, demonstrating significantly superior technical effects compared to existing technologies.

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] With the continuous improvement of industrial automation, processing equipment for door and window profiles is also constantly evolving. Early equipment often had limited functionality, requiring manual handling and positioning of profiles between different workstations, resulting in low efficiency and difficulty in guaranteeing processing accuracy. To improve efficiency and achieve multi-functional processing, modularly designed processing equipment has emerged, distributing different processing functions (such as drilling, milling, and sawing) across different independent modules. However, while this modular design improves automation to some extent, it also introduces new problems. Because each module is relatively independent, the process of transferring and repositioning profiles between modules is complex, easily leading to accumulated errors that affect the processing accuracy and stability of the final product. Furthermore, the collaborative control and management of multiple independent modules increases system complexity and cost. For example, in scenarios requiring multi-faceted drilling and milling and fixed-length sawing of profiles, traditional solutions might require completing drilling and milling in one module before transferring the profile to another for sawing. This step-by-step approach is not only time-consuming but also makes it difficult to guarantee accurate secondary positioning during workpiece transfer, thus affecting processing quality. To overcome these limitations of existing technologies, this application proposes a highly integrated door and window profile processing equipment, which improves processing accuracy and stability through optimized structural design. Specifically, the door and window profile processing equipment of this application includes a feeding area, a sawing area, and an unloading area. The sawing area is equipped with a movable four-sided drilling and milling structure and a sawing device, as well as fixtures for positioning and clamping the profile workpieces, thereby efficiently and accurately completing the drilling, milling, and sawing processing of the profiles in a continuous process.

[0037] This application provides a door and window profile processing equipment designed for automated processing of profile workpieces used in door and window manufacturing. The equipment typically operates on a production line and includes a feeding area 100 for receiving raw profiles, a sawing area 200 for performing the main processing operations, and an unloading area 300 for collecting and processing finished profiles. The profile workpieces sequentially pass through these areas along a predetermined conveyor channel. Within the core sawing area 200, a four-sided drilling and milling structure 210 and a sawing device 240 are integrated; these are key components for completing the drilling, milling, and sawing of the profiles. Furthermore, the equipment is equipped with fixtures for reliable positioning and clamping of the profile workpieces during processing, ensuring processing stability and accuracy.

[0038] Reference Figure 1As shown, the door and window profile processing equipment of this application mainly consists of a feeding area 100, a sawing area 200, and an unloading area 300. The feeding area 100 is located at the beginning of the equipment and is responsible for feeding the profile workpieces to be processed into the equipment. The feeding area 100 can be implemented using various known conveying mechanisms, such as roller conveyors composed of rollers, belt conveyors composed of belts, or other suitable conveying methods. Its main function is to smoothly transport the profiles to the downstream processing area. The sawing area 200 is located downstream of the feeding area 100 and is the core processing area of ​​the equipment, where the profile workpieces undergo drilling, milling, and sawing processes. The unloading area 300 is located downstream of the sawing area 200 and is used to receive the processed profile workpieces output from the sawing area 200 for stacking or further processing.

[0039] Within the sawing zone 200, a four-sided drilling and milling structure 210 is provided for drilling and milling different sides of the profile workpiece. This four-sided drilling and milling structure 210 is designed to move along the conveying direction of the profile workpiece, i.e., the X-axis direction, to process the profile at different positions. The four-sided drilling and milling structure 210 has machining tools 214 capable of machining in the four directions of the profile: up, down, left, and right.

[0040] Compared with existing technologies, this application integrates machining tools 214 in different directions onto a four-sided drilling and milling structure 210. This integrated design significantly improves the compactness and synergy of the equipment. This application reduces the number of workpiece transfers and the need for repositioning, thereby effectively reducing accumulated errors and improving machining accuracy. Simultaneously, the four-sided drilling and milling structure 210, which moves along the profile workpiece conveying direction, allows the equipment to drill and mill at different positions along the length of the profile, increasing machining flexibility. Therefore, this application, through structural integration, overcomes the problems of low equipment integration, poor synergy, and insufficient machining accuracy and stability in existing technologies, demonstrating significant technological advancement.

[0041] The working process of the door and window profile processing equipment of this application is roughly as follows: First, the profile workpiece to be processed is fed into the equipment through the feeding area 100. Next, the profile workpiece is conveyed to the sawing area 200. Subsequently, the movable four-sided drilling and milling structure 210 moves along the conveying direction of the profile according to a preset program, and uses its four-sided cutting tools to perform the required drilling and milling processing on the profile. After the drilling and milling processing is completed, the sawing device 240 performs fixed-length sawing on the profile workpiece. After all processing operations are completed, the processed profile is conveyed to the unloading area 300 for collection or subsequent processing.

[0042] In this process, the feeding area 100 automatically feeds in the profiles, serving as the starting point for the entire continuous processing flow. The sawing area 200, as the core processing area, integrates drilling and milling functions, avoiding frequent workpiece transfers between different stations—a key factor in improving efficiency and precision. The unloading area 300 ensures a smooth completion of the processing flow and the orderly output of finished products. The mobility of the four-sided drilling and milling structure 210 allows the equipment to adapt to drilling and milling requirements of different lengths and positions, while its four-sided processing capability enhances the comprehensiveness of the processing. The sawing device 240 is responsible for precise, fixed-length cutting. Through the coordinated operation of the feeding area 100, sawing area 200, and unloading area 300, efficient, high-precision, and highly stable automated processing of door and window profiles is achieved.

[0043] Furthermore, referring to Figure 2 As shown, the four-sided drilling and milling structure 210 is mounted on a frame 211, which serves as the basic support frame for the entire structure. Slide rails 212 are provided on both sides of the frame 211 along the conveying channel of the profile workpiece. These slide rails 212 can be linear guides or other types of guiding mechanisms, providing a path for the four-sided drilling and milling structure 210 to move along the profile conveying direction (X-axis direction). A square mounting bracket 213 is mounted on the slide rail 212. The mounting bracket 213 can slide smoothly along the slide rail 212 via a slider or other connecting piece that mates with it, thereby enabling the overall movement of the four-sided drilling and milling structure 210 along the X-axis direction.

[0044] Specifically, the frame 211 provides a platform for mounting and supporting the various components of the four-sided drilling and milling structure. The slide rail 212 defines the movement trajectory of the four-sided drilling and milling structure 210, ensuring it moves along a predetermined straight path to process profiles at different positions along its length. The mounting bracket 213 is the core component carrying the machining tools 214; its square structure facilitates the arrangement of tools in four directions. Machining tools 214 are respectively arranged in the four directions (up, down, left, and right) of the mounting bracket 213. These machining tools 214 are mounted on their respective moving mechanisms, allowing them to move independently along the Y-axis (a horizontal direction perpendicular to the conveying direction) and the Z-axis (a direction perpendicular to the horizontal plane). For example, the machining tools 214 in each direction can be mounted on a two-dimensional moving platform composed of linear guides and a drive motor, thereby achieving independent movement in the YZ plane. This independent movement capability allows the machining tools 214 to be precisely positioned at any specified position on the profile workpiece for drilling or milling.

[0045] Furthermore, the four-sided drilling and milling structure 210 is equipped with a total of 13-axis drive control modules. Specifically, the "13 axes" here refers to the number of independently controllable motion axes in the entire four-sided drilling and milling structure 210. The machining tools 214 in the four directions on the front of the mounting bracket 213 each have Z-axis and Y-axis degrees of freedom, so the front of the mounting bracket 213 has a total of 8-axis drive control modules. Similarly, the machining tools 214 in the left and right directions are located on the back of the mounting bracket 213, and each machining tool 214 in each direction also has Z-axis and Y-axis degrees of freedom, so the back of the mounting bracket 213 has a total of 4-axis drive control modules. In addition, the entire frame 211 achieves free movement in the X-axis direction through the X-axis drive module, for a total of 13-axis drive control modules, providing a motion control basis for realizing multi-directional, multi-degree-of-freedom drilling and milling of profile workpieces.

[0046] By configuring a 13-axis drive control module, the independent movement of machining tools in different directions of the mounting bracket along the Y and Z axes can be precisely controlled, as well as the movement of the entire mounting bracket 213 along the X axis. This multi-axis control system is key to realizing four-sided drilling and milling, improving machining efficiency, and ensuring machining accuracy. Compared to the complex double-slide structure that may be used in existing technologies, the 13-axis drive control module simplifies the mechanical structure and reduces manufacturing costs through integrated control. At the same time, through precise motion control, it improves the stability of the machining process, ultimately enhancing drilling and milling efficiency and machining quality. This 13-axis drive control module controls the collaborative work of machining tools in various directions. Since machining tools 214 in different directions all have degrees of freedom in the Y and Z axes, when performing complex machining, such as simultaneously milling or drilling different shapes on the four sides of a profile workpiece, the movement of all machining tools 214 can be precisely coordinated and controlled. This ensures that each machining tool 214 processes according to a predetermined program and trajectory, ultimately machining the required shape and size on the four sides of the profile workpiece. Throughout the machining process, the 13-axis drive control module ensured the coordination and precision of all tool movements, achieving efficient and stable four-sided drilling and milling.

[0047] Therefore, by setting up the frame 211, slide rail 212, and mounting bracket 213, this application provides a basic framework for a four-sided drilling and milling structure 210 capable of moving along the profile conveying direction. More importantly, machining tools 214 capable of independently moving along the Y-axis and Z-axis are set in the four directions of the mounting bracket 213, enabling the four-sided drilling and milling structure 210 to perform multi-directional, multi-position, and high-precision drilling and milling on profile workpieces. Compared with existing technical solutions that can only perform machining in fixed positions or limited directions, this structure provides greater machining flexibility and adaptability, and is a key component for realizing integrated and high-efficiency profile machining, significantly improving the processing capacity and automation level of the equipment.

[0048] Furthermore, referring to Figure 2 and Figure 3 As shown, a through hole is provided on the mounting bracket 213 of the four-sided drilling and milling structure 210. The size and shape of the through hole are designed to allow the profile workpiece to pass through smoothly. During the conveying process, the profile workpiece passes through the through hole on the mounting bracket 213 and enters the processing area inside the mounting bracket 213 to receive drilling and milling operations from the machining tools 214 in the four directions of up, down, left, and right.

[0049] Specifically, the through holes on the mounting bracket 213 serve as channels for the profile workpiece to move within the four-sided drilling and milling structure 210, ensuring that the profile workpiece can be fed into the working range of the machining tool 214. Simultaneously, a lifting structure 215 is provided at the bottom of the frame 211 of the four-sided drilling and milling structure 210. The function of this lifting structure 215 is to lift the entire frame 211 and its mounted components (including the mounting bracket 213 and the machining tool 214) off the ground at a certain height. This creates a sufficiently large operating space between the bottom of the mounting bracket 213 and the ground. This operating space is specifically designed to accommodate the space required for the machining tool 214 under the mounting bracket 213 to move in the Z-axis direction. Since the machining tool 214 needs to move downwards to machine the bottom of the profile workpiece, without sufficient space, its range of movement will be limited, or it may even be unable to function properly. The lifting structure 215 can be a simple support leg or a height-adjustable support mechanism; its core function is to provide the necessary clearance at the bottom.

[0050] Therefore, by providing through holes in the mounting bracket 213, it is ensured that the profile workpiece can smoothly enter the processing area. Furthermore, by providing a lifting structure 215 at the bottom of the frame 211, sufficient movement space is provided for the machining tool 214 located below the mounting bracket 213, ensuring that the lower tool can properly and effectively process the bottom of the profile. These additional technical features improve the function and layout of the four-sided drilling and milling structure 210, enabling it to truly achieve four-sided machining of the profile workpiece, enhancing the equipment's processing capacity and practicality. Compared to solutions that only have basic movement and tool configuration, this solution considers the space requirements in actual processing and has better engineering practicality.

[0051] Furthermore, referring to Figure 2 , Figure 3 and Figure 4As shown, a follower fixture 220 is provided on the mounting frame 213 of the four-sided drilling and milling structure 210. The follower fixture 220 is designed to move synchronously with the mounting frame 213 so that it can locally and dynamically clamp the workpiece when the four-sided drilling and milling structure 210 is machining the profile workpiece. The core component of the follower fixture 220 is the clamping mechanism 221, which is located inside the mounting frame 213.

[0052] Specifically, the follower fixture 220 is a clamping unit that can move along with the four-sided drilling and milling structure 210. Its main function is to fix the profile workpiece near the tool's point of action during drilling and milling, thereby improving the local rigidity and stability of the machining process. The follower fixture 220 includes a clamping mechanism 221, which is the execution part that directly applies clamping force to the profile workpiece. The clamping mechanism 221 further includes a mounting part 222 and a clamping part 223. The mounting part 222 is used to securely fix or connect the entire clamping mechanism 221 to the mounting frame 213. For example, the mounting part 222 can be welded inside the mounting frame 213. The clamping part 223 is the component that directly contacts the profile workpiece and applies clamping force. The shape and structure of the clamping part 223 can be designed according to the cross-sectional shape of the profile to be processed, for example, using V-blocks, flat jaws, or other customized clamping surfaces to ensure effective envelopment and fixation of the profile. The clamping mechanism 221 can be driven by pneumatic, hydraulic or electric means to realize the action of the clamping part 223, thereby clamping and releasing the profile workpiece.

[0053] Therefore, by providing a follower fixture 220 and its internal clamping mechanism 221 on the movable mounting frame 213, this application provides a solution for localized, follower-type clamping of profile workpieces during drilling and milling. The follower fixture 220 moves together with the four-sided drilling and milling structure 210, ensuring that the clamping point is always close to the working position of the machining tool 214. This close-range clamping can more effectively suppress vibration and deformation of the profile during machining, especially providing more reliable support when performing side or bottom drilling and milling. Compared to solutions that only fix the workpiece at both ends or use fixed fixtures, the application of the follower fixture 220 significantly improves the local stability and accuracy of the drilling and milling process, representing a significant improvement in the overall machining quality of the equipment.

[0054] Furthermore, referring to Figure 4 As shown, an auxiliary follower fixture 224 is also provided. This auxiliary follower fixture 224 is connected to the mounting bracket 213 and can also move together with the four-sided drilling and milling structure 210. This auxiliary follower fixture 224 works in conjunction with the clamping mechanism 221 to position and clamp the profile workpiece.

[0055] Specifically, the auxiliary follower fixture 224 is mounted on the mounting bracket 213. Its position is carefully designed so that its clamping parts, along with those of the clamping mechanism 221, are located on either side of the working area of ​​the machining tool 214 in the conveying direction (X-axis direction) of the profile workpiece. This means that when the machining tool 214 performs drilling and milling on the profile workpiece, the clamping mechanism 221 and the auxiliary follower fixture 224 will clamp the profile workpiece from both sides of the machining point. This dual-sided clamping method provides a more stable and comprehensive fixation of the profile workpiece. When the machining tool 214 is working, the clamping mechanism 221 and the auxiliary follower fixture 224 will operate simultaneously to precisely position the profile workpiece and clamp it circumferentially. Circumferential clamping refers to applying clamping force from multiple directions on the profile cross-section to prevent the profile from twisting or shifting laterally under machining forces. For example, the clamping mechanism 221 and the auxiliary follower clamp 224 can clamp the profile from opposite sides or multiple angles to form a closed or semi-closed clamping envelope.

[0056] Therefore, by adding an auxiliary follower fixture 224 and having it work in conjunction with the clamping mechanism 221 to position and circumferentially clamp the profile workpiece on both sides of the working area of ​​the machining tool 214, this application provides a more reliable and stable clamping solution. This double-sided, circumferential clamping method can more effectively resist the complex stresses generated during drilling and milling, preventing deformation or displacement of the profile workpiece, especially for profiles with complex cross-sectional shapes or thin walls, where the effect is more significant. Compared to solutions using only single-sided or non-circumferential clamping, this solution significantly enhances the deformation resistance and stability of the machining process, further improving the accuracy and quality of drilling and milling, and is an important optimization for improving equipment performance.

[0057] Furthermore, referring to Figure 5 As shown, the machining tool 214 includes a tool moving plate 231, on which a swing cylinder 232 is mounted. The swing cylinder 232 is a pneumatic actuator capable of swinging at a certain angle. A turntable 233 is rotatably connected to the tool moving plate 231. The drilling and milling tool 234, which is used for the actual drilling and milling operation, is mounted on the turntable 233. The extension rod of the swing cylinder 232 is connected to the turntable 233. Through the extension and retraction of the swing cylinder 232, the turntable 233 can be driven to rotate around its axis of rotation at a certain angle, thereby achieving the swing angle machining of the drilling and milling tool 234.

[0058] Specifically, the tool moving plate 231 is the basic platform supporting the tilting cylinder 232 and the drilling and milling cutter 234. The tilting cylinder 232 and the turntable 233 constitute the key mechanism for realizing the tool tilting function. By controlling the extension and retraction of the tilting cylinder 232, the rotation angle of the turntable 233 can be precisely controlled, allowing the drilling and milling cutter 234 to enter the profile workpiece at different angles for machining, such as performing inclined hole drilling or inclined surface milling. This tilting capability greatly increases the processing flexibility of the equipment and can meet the needs of more complex profile machining. In addition, a first limiting cylinder 235 is installed on the turntable 233, adjacent to the drilling and milling cutter 234. The first limiting cylinder 235 is designed to resist the return tendency generated by the milling force when the drilling and milling cutter 234 is performing milling. During the milling process, the tool is subjected to a reaction force from the workpiece, which may cause slight displacement of the tool or its supporting structure, affecting the machining accuracy. The first limiting cylinder 235 counteracts or weakens this return tendency by applying a reverse supporting force. Its working state is coordinated with the swing angle direction of the swing cylinder 232 to provide the best support effect.

[0059] The tool moving plate 231, serving as the base of the entire mechanism, can be made of high-strength metal to ensure the stability and rigidity of the mechanism. The tilting cylinder 232 is fixedly mounted on the tool moving plate 231, serving as the power source for driving the rotary table 233 to rotate. In a preferred embodiment, the tilting cylinder 232 can be a pneumatic cylinder, utilizing compressed air as power, offering advantages such as fast response and simple structure. However, in some preferred embodiments, other types of drive devices, such as hydraulic cylinders or electric cylinders, can also be used. The rotary table 233 and the tool moving plate 231 are rotatably connected, for example, through bearings, to ensure that the rotary table 233 can rotate flexibly relative to the tool moving plate 231. The drilling and milling cutter 234 is mounted and fixed on the rotary table 233; as the rotary table 233 rotates, the angle of the drilling and milling cutter 234 also adjusts. The specific type of drilling and milling cutter 234 can be selected according to actual machining requirements; for example, it can be a high-speed steel drill bit, a carbide end mill, etc. The first limit cylinder 235 is mounted on the turntable 233 and is specifically located on one side of the drilling and milling cutter 234. Its key function is to provide locking force when milling the profile workpiece to resist the reset tendency of the drilling and milling cutter 234 during the milling process.

[0060] To achieve reliable locking of the turntable 233, this application also ingeniously designs a mating structure between the first arc-shaped groove and the first limiting slider. Specifically, the first arc-shaped groove is set on the tool moving plate 231, and its arc shape is adapted to the rotation trajectory of the turntable 233. The first limiting slider forms a sliding fit with the first arc-shaped groove, and the first limiting cylinder 235 is mounted on the turntable 233 through the first tailstock mounting block. The extension rod of the first limiting cylinder 235 is hinged to the first limiting slider through the first limiting connector.

[0061] When the tilting cylinder 232 retracts to drive the turntable 233 and the drilling and milling cutter 234 to rotate at an angle and perform machining in an inclined state, the cutting force generated by the drilling and milling will force the turntable 233 to tend to return to its original position, resulting in a deviation in the machining angle or even failure. The first limiting connector is connected to the telescopic rod of the first limiting cylinder 235 through a hinge point, such as a pin. At this time, the first limiting cylinder 235 is in a retracted state, and its telescopic rod retracts, causing the first limiting connector to become inclined, forming an angle with the telescopic rod. The position of the first limiting slider in the first arc-shaped groove is limited by the inclined angle of the first limiting connector. When the cutting force attempts to make the drilling and milling cutter 234 return to its original position counterclockwise, the first limiting slider is fixed in the first arc-shaped groove by the inclined first limiting connector, thereby preventing the turntable 233 from rotating counterclockwise. During machining, as the milling cutter 234 continues cutting, the cutting force constantly changes. The first limiting cylinder 235 maintains the tilted state of the first limiting connector by continuously contracting, ensuring that the first limiting slider is always locked in the first arc-shaped groove, forming a dynamic static balance. Simultaneously, the hinged design allows the first limiting connector to adapt to angle changes within a certain range, avoiding jamming or stress concentration caused by rigid connections. This design, through mechanical constraints and dynamic limiting, resists the counter-clockwise reset tendency caused by the milling cutter 234 cutting, ensuring the stability of the tool during tilted machining and acting as a locking mechanism. When the tilting cylinder 232 extends, driving the turntable 233 to resume milling from its rotating state, the first limiting cylinder 235 extends its telescopic rod, pushing the first limiting connector to rotate around the hinge point, tilting it in the opposite direction to its contracted state, fixing the first limiting slider in the first arc-shaped groove to resist the clockwise rotation tendency caused by the cutting force of the milling cutter 234 during milling, ensuring machining accuracy and efficiency.

[0062] Therefore, by integrating the tilting cylinder 232 and the rotary table 233 into the machining tool unit, this application enables the drilling and milling tool 234 to have tilting machining capability, significantly improving the machining flexibility and functional versatility of the equipment. Simultaneously, by setting the first limit cylinder 235, the return tendency generated during milling is effectively resisted, enhancing the rigidity and stability of the tool, thereby improving the milling accuracy and tool life. Compared to solutions lacking tilting function or effective anti-return support, this solution has significant advantages in improving machining capability and ensuring machining quality, representing an important technical improvement for enhancing the overall performance of the equipment.

[0063] Furthermore, referring to Figure 6 and Figure 8 As shown, in the sawing zone 200, in addition to the four-sided drilling and milling structure 210, a sawing device 240 is also provided. This sawing device 240 is a key component for performing fixed-length cutting of profile workpieces. The sawing device 240 includes at least one 90-degree saw blade 241. This 90-degree saw blade 241 is a circular saw blade or band saw blade capable of making cuts perpendicular to the surface of the profile.

[0064] Specifically, the sawing device 240 functions to precisely cut profile workpieces, whether milled or directly fed, to a preset length. The 90-degree saw blade 241 is the cutting tool that performs the cutting operation. The "90 degrees" refers to the fact that its cutting direction is perpendicular to the surface of the profile workpiece, thus obtaining a flat cross-section. The 90-degree saw blade 241 is mounted on a corresponding drive and feed mechanism, enabling it to saw along the Y-axis direction. The Y-axis direction is generally defined as a horizontal direction perpendicular to the profile workpiece's transport direction (X-axis direction). Therefore, the sawing direction of the 90-degree saw blade 241 is perpendicular to the profile workpiece's transport direction. This means that after the profile workpiece is transported to a designated position in the X-axis direction, the 90-degree saw blade 241 feeds from the side (Y-axis direction), sawing the profile vertically. The sawing device 240 may include a motor for driving the saw blade's rotation, a guide rail and drive mechanism for controlling the saw blade's feed, and a structure for supporting and positioning the saw blade.

[0065] Therefore, by setting at least one 90-degree saw blade 241 along the Y-axis in the sawing zone 200, this sawing method is a basic operation in door and window profile processing, used to cut long profiles into the required component lengths. Integrating the sawing device 240 with the four-sided milling structure 210 in the same area reduces workpiece transfer steps and improves processing efficiency. The 90-degree saw blade 241's cutting method, perpendicular to the conveying direction along the Y-axis, ensures the flatness and perpendicularity of the cut surface, meeting the cutting quality requirements of door and window profiles. Compared to solutions that require transferring workpieces to independent sawing stations, this integrated design simplifies the process, improves the compactness and synergy of the equipment, and is an important component for achieving efficient continuous processing.

[0066] Furthermore, referring to Figure 6 As shown, a telescopic support clamp 242 is provided. This telescopic support clamp 242 is used to provide additional support and clamping for the profile workpiece during sawing operations. The telescopic support clamp 242 includes a Z-axis clamping module 243. The Z-axis clamping module 243 is disposed on the side of the 90-degree saw blade 241. Its main function is to clamp the profile workpiece in the Z-axis direction (perpendicular to the horizontal plane) at the moment when the 90-degree saw blade 241 is about to completely cut the profile workpiece.

[0067] Specifically, the Z-axis clamping module 243 typically includes one or more clamping blocks capable of applying a vertical clamping force to the profile workpiece from above. Positioned on the side of the 90-degree saw blade 241, the Z-axis clamping module 243 secures the workpiece close to the cutting position during sawing. When the profile is about to be completely cut, the material's cohesion weakens, making it prone to wobbling or uneven fracture surfaces. At this time, the clamping action of the Z-axis clamping module 243 effectively stabilizes the workpiece, preventing displacement or breakage at the moment of cutting, thus ensuring the quality and accuracy of the cut surface. Furthermore, the telescopic support fixture 242 also includes a Y-axis drive module 244 connected to the Z-axis clamping module 243. The Y-axis drive module 244 drives the Z-axis clamping module 243 to telescopically move in the Y-axis direction. This means that the Z-axis clamping module 243 can not only perform clamping actions in the Z-axis direction but also adjust its position along the Y-axis direction to accommodate profile workpieces of different widths or cutting positions. The Y-axis drive module 244 can be implemented by a cylinder, electric push rod, or lead screw transmission mechanism.

[0068] Therefore, by setting up a telescopic support clamp 242, which includes a Z-axis clamping module 243 located on the side of the saw blade and a Y-axis drive module 244 for driving its Y-axis extension and retraction, this application provides an auxiliary clamping solution specifically for the sawing process. This solution can provide additional vertical clamping support at the critical moment when the profile is about to be sawn off, effectively preventing workpiece shaking and cross-sectional cracking, and greatly improving the stability of the sawing process and the accuracy of the cross-section. The Y-axis extension and retraction function increases the adaptability of the clamp. Compared with the solution of relying solely on general-purpose clamps for sawing fixation, the design of this telescopic support clamp 242 is more targeted, plays an important role in improving sawing quality, and is an important component in ensuring the overall processing accuracy of the equipment.

[0069] Furthermore, referring to Figure 1 and Figure 7As shown, a pressure clamp 250 is provided in the area between the feeding area 100 and the sawing area 200. This pressure clamp 250 is positioned in the transition area where the profile workpiece enters the sawing area from the feeding area, and is used to position and clamp the profile workpiece in this area. The pressure clamp 250 includes a pressure clamping part 251.

[0070] Specifically, the downward clamping fixture 250 is a clamp that applies clamping force to a profile workpiece from above. It is positioned between the feeding area 100 and the sawing area 200, and functions when the profile workpiece first enters the processing area or when auxiliary support is needed during processing. The core of the downward clamping fixture 250 is the downward clamping part 251, which is the component that directly contacts the top of the profile workpiece and applies clamping force. The downward clamping part 251 is designed to move vertically along the Z-axis to accommodate profile workpieces of different heights or to lift and release the workpiece when needed. Simultaneously, the downward clamping part 251 can also rotate around the Z-axis. This Z-axis rotation capability allows the downward clamping part 251 to adjust its angle or direction to better adapt to the shape of the profile workpiece or to clamp it at a specific position. When the profile workpiece is being processed, the downward clamping part 251 moves downward along the Z-axis, applying clamping force to the profile workpiece and fixing it in a predetermined position. This top-mounted fixing method effectively prevents the profile workpiece from shifting horizontally or vertically, providing additional stability, especially when machining the sides or bottom. The downward clamping part 251 can be a pressure block, roller, or other structure suitable for applying pressure to the top of the profile.

[0071] Therefore, by providing a pressing clamp 250 between the feeding area 100 and the sawing area 200, and by giving its pressing clamping part 251 the ability to lift and rotate around the Z-axis, this application provides a flexible and diverse clamping solution. The pressing clamp 250 can be used for initial positioning and fixing when the profile enters the processing area, and can also serve as an auxiliary support during processing, enhancing overall clamping stability. The Z-axis lifting and rotation capabilities allow the clamp to adapt to the needs of different workpieces and different processing stages. Compared to solutions that rely solely on lateral or bottom clamping, the pressing clamp 250 provides a method of fixing from above, increasing the dimensionality and flexibility of clamping, and helping to improve the stability and adaptability of the entire processing flow.

[0072] Furthermore, referring to Figure 7 As shown, in this pressing clamp 250, a specific drive mechanism is provided to realize the lifting and lowering function of the pressing clamping part 251 along the Z-axis and the rotation function around the Z-axis. Specifically, the pressing clamp 250 includes a lifting mechanism 252 for driving the pressing clamping part 251 to move up and down along the Z-axis, and a rotating mechanism 253 for driving the pressing clamping part 251 to rotate around the Z-axis.

[0073] Specifically, the lifting mechanism 252 is configured to provide linear motion in the vertical direction, thereby controlling the up-and-down position of the pressing clamping part 251. The lifting mechanism 252 can be implemented in various forms, such as a cylinder, hydraulic cylinder, electric actuator, or a lead screw or rack and pinion mechanism driven by a motor. The rotating mechanism 253 is configured to provide rotational motion about the Z-axis, thereby controlling the rotation angle of the pressing clamping part 251. The rotating mechanism 253 can be driven by a rotary cylinder, rotary hydraulic cylinder, stepper motor, or servo motor. To enable the pressing clamping part 251 to rotate about the Z-axis while simultaneously lifting and lowering it, the lifting mechanism 252 and the rotating mechanism 253 are connected via a rotary joint 254. The rotary joint 254 allows the linear motion of the lifting mechanism 252 to be transmitted to the rotating mechanism 253, while simultaneously allowing the rotating mechanism 253 to freely rotate the pressing clamping part 251 without interfering with the lifting motion. The output end of the rotating mechanism 253 is directly connected to the pressing clamping part 251, thereby transmitting the rotational power to the pressing clamping part 251.

[0074] Therefore, by equipping the pressing clamping part 251 of the pressing clamp 250 with an independent lifting mechanism 252 and a rotating mechanism 253, and cleverly connecting them through a rotary joint 254, this application provides a pressing clamping scheme that enables precise control of the clamping part. The lifting mechanism 252 ensures that the pressing clamping part 251 can accurately reach the predetermined Z-axis height for clamping or lifting, adapting to profiles of different thicknesses. The rotating mechanism 253 allows the pressing clamping part 251 to adjust its angle to contact and fix the profile in the best posture, or to rotate and avoid it when necessary. This clamping part with independent lifting and rotating capabilities greatly improves the flexibility and adaptability of the pressing clamp 250, enabling more precise and reliable positioning and fixing of profile workpieces, especially when multi-angle or complex shape processing of profiles is required, its advantages are more obvious. Compared with single-function fixing or only lifting clamps, this application provides more refined control capabilities, which helps to improve the automation level and processing accuracy of the equipment.

[0075] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
