Description

Technical Field

[0001] This invention belongs to the field of building construction equipment technology, specifically relating to a grooving machine for slotting U-shaped brackets during wall panel installation and a method for grooving using the grooving machine. Background Technology

[0002] The traditional method for installing ALC partition panels is to directly fit the U-shaped bracket onto the ALC partition panel without taking any other precautions. This installation method results in the U-shaped bracket extending beyond the surface of the ALC partition panel on both sides.

[0003] If the wall is only plastered, the U-shaped brackets will protrude beyond the surface of the wall panel, making it impossible to cover them. This will result in raised areas at each bracket location, affecting the wall's appearance and hindering the plastering process. If painting is used, the U-shaped brackets will increase the overall thickness of the paint application. The U-shaped brackets themselves are 1.5 mm thick; considering the pre-installed gaps and subsequent deformation, each side will extend at least 3 mm beyond the wall's surface. Normally, a thin layer of paint is around 10 mm thick, but due to the U-shaped brackets, the paint thickness will increase by 30%. This not only leads to significant material waste but also prolongs the construction time.

[0004] To address the issues of low efficiency and poor quality in manual grooving, mechanized grooving equipment has emerged in the existing technology, such as the "A Plate Grooving Machine" with announcement number CN209174972U. Its technical solution includes a frame, an electrical control cabinet, a workbench, a horizontally moving sliding mechanism, and a grooving device. The grooving device consists of an L-shaped fixed base, a motor, a milling cutter, and rollers symmetrically arranged on both sides of the milling cutter. The grooving is achieved by driving the grooving device to move horizontally through the sliding mechanism.

[0005] However, the existing panel grooving machine still has many shortcomings that make it difficult to meet the needs of rapid on-site grooving of ALC partition wall panel U-shaped brackets, as follows: 1. Limited Work Efficiency: The single milling cutter structure requires the plate to be horizontally positioned on the worktable before grooving, enabling grooving only on one side. If grooves to fit the U-shaped bracket need to be machined on both sides of the plate, secondary positioning and two cutting operations are required. This is not only cumbersome, time-consuming, and costly, but also prone to causing asymmetry in the grooves due to positioning deviations between the two operations, failing to meet the precise dimensional requirements for the installation of the U-shaped bracket.

[0006] II. Limitations in Applicability: The equipment's operation heavily relies on a fixed workbench and horizontal sliding mechanism. Its overall size is large and its mobility is poor, making it only suitable for mass processing of standardized panels in a factory. However, on construction sites, where large ALC partition panels are difficult to transport and require on-site adaptation and processing, this equipment cannot achieve flexible operation. Furthermore, it requires significant space on the construction site, making it difficult to deploy in confined spaces and unable to adapt to the pace of on-site grooving.

[0007] In view of the shortcomings of the existing technology, there is an urgent need for a grooving device with high efficiency and strong adaptability to different scenarios to solve the core pain point of grooving U-shaped card slots for ALC partition boards. Summary of the Invention

[0008] This invention aims to overcome the problems of protruding panel surface, high subsequent construction costs, and low efficiency caused by the lack of pre-set slots in the installation of traditional ALC partition wall panel U-shaped brackets. At the same time, it solves the defects of existing panel grooving machines, such as limited operating efficiency and limited application scenarios. It provides a grooving machine and grooving method to achieve efficient on-site grooving operations and reduce construction costs.

[0009] The technical solution of this invention: This invention provides a grooving machine, comprising a frame, milling cutters, a drive mechanism, and a positioning and guiding device. Two milling cutters are arranged in parallel and rotatably mounted on the frame for simultaneously cutting grooves on both sides of a sheet metal surface. The drive mechanism is mounted on the frame and connected to the milling cutters for driving their rotation. The positioning and guiding device is mounted on the side of the frame near the milling cutters. The positioning and guiding device includes a reference positioning element, a depth positioning element, and a lateral positioning element. The reference positioning element slides against the end face of the sheet metal. The depth positioning element limits the cutting depth. The lateral positioning element clamps both sides of the sheet metal and can slide along the cutting depth direction. The reference positioning element, depth positioning element, and lateral positioning element enclose a directional sliding space to guide the milling cutters to slide directionally along the cutting position on the sheet metal to a specified cutting depth. The two milling cutters are located within the directional sliding space, and their axes are perpendicular to the positioning plane formed by the reference positioning element.

[0010] According to one embodiment of the present invention, the reference positioning member is mounted on the frame; the depth positioning member is mounted on the frame and close to one end of the reference positioning member, and the positioning plane formed by the depth positioning member is perpendicular to the positioning plane formed by the reference positioning member; the lateral positioning member is mounted on the frame and located on both sides of the reference positioning member.

[0011] According to an embodiment of the present invention, the lateral positioning member includes positioning wheels, and at least two rotatable positioning wheels are provided on both sides of the reference positioning member; the distance between the positioning wheels on one side of the reference positioning member and the positioning wheels on the other side is adapted to the thickness of the plate.

[0012] According to an embodiment of the present invention, the lateral positioning member further includes a connecting plate and a positioning seat; one end of the connecting plate is mounted on the machine frame, and the other end mounts the positioning seat; the positioning wheels are rotatably mounted on the positioning seat; each positioning wheel corresponds to one positioning seat, and each positioning seat corresponds to one connecting plate; the connecting plates mounted on one side of the machine frame and the connecting plates on the other side are arranged in parallel, and there is an elastic space between the parallel connecting plates for the positioning wheels on both sides to adaptively clamp the two side surfaces of the plate.

[0013] According to an embodiment of the present invention, the driving mechanism uses two motors, and each motor is correspondingly connected to one milling cutter.

[0014] According to an embodiment of the present invention, it further includes two handles mounted at both ends of the machine frame, which are used to hold and push the grooving machine to move to realize cutting and grooving.

[0015] According to an embodiment of the present invention, it further includes a power supply device, and the power supply device is a battery for supplying power to the driving mechanism; the battery and the positioning and guiding device are respectively mounted on the two side surfaces of the machine frame.

[0016] According to an embodiment of the present invention, the machine frame is a "U" - shaped structure, which is composed of two cover plates and two vertical plates; a space for accommodating the driving mechanism is formed between the two cover plates, the two vertical plates are vertically mounted at both ends of the cover plates, and the handles are mounted on the outer sides of the vertical plates.

[0017] According to an embodiment of the present invention, the reference positioning member is mounted on the overall two cover plates, the depth positioning member is mounted between the tops of the two vertical plates, and the lateral positioning member is mounted on the inner sides of the two vertical plates.

[0018] The present invention also provides a method for grooving using the grooving machine of the above - mentioned embodiment, which includes the following steps: First, start the driving mechanism to drive the two milling cutters to rotate at high speed; Second, hold the grooving machine by hand and put the positioning and guiding device on the starting position of the plate cutting: ① Reference positioning: make the reference positioning member fit the end face of the plate; ② Lateral positioning: clamp the two side surfaces of the plate through the lateral positioning member; Third, push the grooving machine to move along the plate, and the milling cutters synchronously cut the two side grooves; Fourth, when the depth positioning member abuts against the top surface of the plate, stop pushing; Fifth, remove the grooving machine to complete grooving.

[0019] The beneficial effects of the present invention: The grooving machine of this invention, through targeted structural innovation and component collaborative design, not only completely solves the inherent defects of traditional ALC partition wall panel U-shaped bracket installation, but also effectively overcomes the core deficiencies of existing panel grooving machines in terms of efficiency and applicability. The specific beneficial effects are as follows: I. Simultaneous completion of double-sided grooving results in a double leap in work efficiency and grooving accuracy.

[0020] This invention employs two parallel milling cutters, enabling simultaneous cutting of grooves matching the U-shaped mounting bracket on both sides of the sheet metal in a single operation, achieving "one-time advance, double-sided grooving." In contrast, existing sheet metal grooving machines are equipped with only a single milling cutter, requiring single-sided grooving to be completed after positioning on the worktable, followed by repositioning for a second cut. This not only increases the grooving time per sheet metal but also easily leads to asymmetrical grooves on both sides due to positioning deviations, failing to meet the precise installation requirements of the U-shaped mounting bracket. The dual-milling-cutter design of this invention significantly improves grooving efficiency, and the spacing error between the grooves on both sides is controlled within a minimal range, fundamentally solving the pain points of low efficiency and poor groove consistency in existing equipment.

[0021] Two-dimensional positioning and guidance ensure stable grooving quality.

[0022] This invention innovatively employs a positioning and guiding device composed of a reference positioning component, a depth positioning component, and a lateral positioning component. The directional sliding space formed by these three components constructs a full-dimensional positioning system: the reference positioning component slides against the end face of the sheet metal, providing an absolutely stable axial reference; the depth positioning component directly limits the cutting depth, ensuring that the depth of each groove is completely uniform; the lateral positioning component clamps both sides of the sheet metal and slides along the cutting direction, effectively preventing lateral deviation of the equipment. This positioning design standardizes the grooving quality, fully meeting the precision requirements of subsequent U-shaped bracket installation.

[0023] Third, it breaks free from the constraints of fixed equipment and adapts to the flexible operation needs of construction sites.

[0024] This invention achieves autonomous guidance through a directional sliding space formed by a positioning and guiding device, completely eliminating the reliance on the "fixed worktable + horizontal sliding mechanism" of existing panel grooving machines. The overall structure is more compact, and mobility is significantly improved. Existing equipment is bulky and can only process standardized panels in batches in the factory. It cannot meet the practical needs of large ALC partition panels on construction sites, which are difficult to transport and require on-site adaptation, thus failing to achieve flexible operation. Furthermore, it has high requirements for construction site space and is difficult to deploy in confined areas. This invention can be carried directly to the installation site by the operator, completing grooving in situ without the need for transportation. It is adaptable to various construction site environments and perfectly matches the construction rhythm of immediate grooving.

[0025] Fourth, it eliminates the defects of traditional installation and significantly reduces subsequent construction costs.

[0026] This invention precisely controls the groove depth using a depth positioning component, ensuring that the U-shaped bracket is completely lower than the surface of the board after installation. Subsequent filling with conventional mortar is sufficient to achieve a smooth surface. This design completely solves the problem of the U-shaped bracket protruding beyond the board surface in traditional grooveless installations, avoiding the protrusion defects during puttying and eliminating the need for increased plaster thickness as in traditional methods. This invention optimizes the construction process from the source, reduces the consumption of mortar and other raw materials, shortens the construction cycle, and significantly reduces overall construction costs.

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Please see Figures 1 to 5This invention provides a grooving machine, including a frame 1, a milling cutter 2, a drive mechanism 3, and a positioning and guiding device 4. The milling cutter 2 is rotatably mounted on the frame 1 and is used to cut and groove a sheet material 10 (such as an ALC partition wall panel). The drive mechanism 3 is mounted on the frame 1 and connected to the milling cutter 2, and is used to drive the milling cutter 2 to rotate to achieve the cutting motion. The positioning and guiding device 4 is mounted on the frame 1, forming a directional sliding space 40 adapted to the thickness of the sheet material 10, and is used to guide the milling cutter 2 to slide directionally along the cutting position on the sheet material 10 to a specified cutting depth.

[0032] The grooving machine provided by this invention, through the coordinated action of the frame 1, milling cutter 2, drive mechanism 3, and positioning and guiding device 4, addresses the traditional construction difficulties of installing U-shaped brackets 30 on ALC partition panels. It demonstrates significant advantages in solving installation defects, improving efficiency, ensuring quality, reducing costs, and enhancing applicability, comprehensively optimizing the construction process. Specifically, the beneficial effects in each aspect are as follows: I. Solving the Defects of Traditional Installation: In traditional construction, the U-shaped bracket 30 is directly fitted onto the ALC partition board, causing the sides to extend beyond the board surface, affecting subsequent puttying or increasing the thickness of the plaster. In this invention, the positioning and guiding device 4 forms a directional sliding space 40 adapted to the thickness of the board 10, which can accurately guide the milling cutter 2 to slide along the preset cutting position to the specified depth, so that the groove size is adapted to the U-shaped bracket 30. After installation, the sides of the U-shaped bracket 30 are lower than the plane of the board 10, and the overall surface is flat after the mortar is filled in the gaps. This completely solves the problem of the U-shaped bracket 30 extending beyond the board surface in traditional installation, ensuring the smooth progress of subsequent processes such as puttying and plastering.

[0033] II. Improved Construction Efficiency and Quality Stability: The drive mechanism 3 provides stable power to the milling cutter 2, and in conjunction with the directional guidance of the positioning guide device 4, enables rapid and standardized grooving. Compared with traditional construction methods without dedicated equipment, the grooving time for a single groove can be shortened to about 15 seconds, significantly improving efficiency. At the same time, the directional sliding space 40 ensures that the depth and position of each groove are consistent, avoiding human error and ensuring the stability of grooving quality, resulting in a uniform installation effect of the U-shaped bracket 30.

[0034] Third, reduced construction costs: Traditional methods require an additional 30% thickness of wall plastering due to the U-shaped bracket 30 extending beyond the panel surface, leading to increased consumption of mortar and other raw materials. This invention, through precise grooving, conceals the U-shaped bracket 30 within the groove, eliminating the need for additional plastering thickness and reducing raw material usage. Simultaneously, the efficient construction process shortens working hours and reduces labor costs, achieving cost reduction in both materials and time.

[0035] IV. Enhanced Construction Convenience and Adaptability: The frame 1 integrates the milling cutter 2, drive mechanism 3, and positioning guide device 4 to form a compact overall equipment, which is convenient for operators to handle and use; the directional sliding space 40 of the positioning guide device 4 ensures stable directional sliding on the plate 10, ensuring the smoothness of the cutting and grooving process. It is simple to operate and easy to learn, and can be used proficiently after a short training period.

[0036] In summary, this invention fundamentally solves the traditional defects in the installation of ALC partition wall panel U-shaped bracket 30 through the structural integration of the frame 1, the efficient cutting of the milling cutter 2 and the drive mechanism 3, and the precise guidance and adaptation design of the positioning guide device 4. At the same time, it achieves comprehensive improvement in efficiency, quality, cost and applicability, and has significant practical and economic value.

[0037] In this embodiment, the positioning guide device 4 includes a reference positioning member 41 for sliding against the end face of the plate 10, a depth positioning member 42 for limiting the cutting depth, and a lateral positioning member 43 for clamping the two side surfaces of the plate 10 and sliding along the cutting depth direction. The reference positioning member 41, the depth positioning member 42, and the lateral positioning member 43 enclose a directional sliding space 40. The milling cutter 2 is located within the directional sliding space 40 and is perpendicular to the positioning plane formed by the reference positioning member 41. In use, the reference positioning member 41 is against the end face of the plate 10. The distance between the depth positioning member 42 and the top surface of the plate 10 is the cutting depth. The lateral positioning member 43 is clamped and slid against the two side surfaces of the plate 10 for positioning. An external force is applied to the frame 1 to push the positioning guide device 4 and the milling cutter 2 to slide along the cutting direction until the depth positioning member 42 abuts against the top surface of the plate 10 and stops. The high-speed rotating milling cutter 2 cuts a groove 20 on the plate 10 during the sliding process.

[0038] The positioning and guiding device 4, as the core positioning component of the grooving machine of this invention, provides precise and stable positioning and guiding guarantee for the U-shaped card seat 30 groove cutting of the ALC partition wall panel through the coordinated action of the reference positioning component 41, the depth positioning component 42, and the lateral positioning component 43, as well as the directional sliding space 40 formed by the three components. The specific beneficial effects are as follows: 1. Achieving precise positioning of the cutting position: The reference positioning component 41 slides against the end face of the plate 10, providing a reliable reference for the entire cutting process. This ensures that the cutting position of the milling cutter 2 is fully matched with the installation requirements of the U-shaped bracket 30, avoiding the groove deviation problem caused by ambiguous positioning in traditional construction. This ensures the compatibility of the U-shaped bracket 30 with the plate 10 after installation from the source.

[0039] II. Strict Control of Cutting Depth: The distance between the depth positioning component 42 and the top surface of the plate 10 directly determines the cutting depth. When the pushing equipment slides to the point where the depth positioning component 42 abuts against the top surface of the plate 10, the cutting automatically stops, ensuring that the depth of each groove is completely consistent and meets the design requirements. This design solves the problem of difficulty in controlling the cutting depth when there is no dedicated equipment, ensuring that the U-shaped bracket 30 is precisely lower than the plane of the plate 10 on both sides after installation, laying the foundation for the flat construction of subsequent processes.

[0040] 3. Preventing lateral displacement during cutting: The lateral positioning component 43 clamps onto both sides of the plate 10 and slides along the cutting depth direction, providing stable lateral support for the equipment and limiting its left-right sway through the clamping force. This design effectively avoids groove deformation or positional displacement caused by equipment shaking during cutting, ensuring the flatness of both sides of the groove and making the U-shaped bracket 30 uniformly stressed, stable, and reliable after installation.

[0041] IV. Forming an directional sliding space adapted to the plate 10: The directional sliding space 40 formed by the reference positioning component 41, the depth positioning component 42 and the lateral positioning component 43 is adapted to the thickness of the plate 10, and the milling cutter 2 is perpendicular to the positioning plane of the reference positioning component 41, ensuring that the cutting direction is parallel to the two sides of the plate 10, ensuring the stability and continuity of the cutting process, and greatly improving the grooving efficiency.

[0042] In summary, the positioning and guiding device 4, through the coordinated positioning and guiding function of multiple components, ensures the quality of grooving from multiple dimensions such as position, depth, and stability. It not only solves many defects of traditional construction, but also provides core support for the efficient and precise operation of the equipment. It is the key to realizing the concealed installation of the U-shaped bracket 30 and optimizing the subsequent construction process.

[0043] The reference positioning component 41 is mounted on the frame 1, and the depth positioning component 42 is mounted on the frame 1 and located near one end of the reference positioning component 41. The positioning plane formed by the depth positioning component 42 is perpendicular to the positioning plane formed by the reference positioning component 41. The lateral positioning components 43 are mounted on the frame 1 and located on both sides of the reference positioning component 41.

[0044] The reference positioning component 41, depth positioning component 42, and lateral positioning component 43, as the core components of the positioning and guiding device 4, form a collaborative positioning mechanism through their respective structural designs and assembly relationships with the frame 1. This provides a key guarantee for the precise and efficient operation of the grooving machine, with the following specific beneficial effects: I. Positioning Reference Function of Reference Positioning Component 41: The reference positioning component 41 is installed on the frame 1 and slides against the end face of the plate 10 during use, providing a stable axial reference for the entire cutting process. This design ensures that the relative position of the cutting starting point of the milling cutter 2 and the end face of the plate 10 is always consistent, avoiding axial displacement of the groove caused by placement deviation of the plate 10 or equipment shaking. This fundamentally guarantees the positional matching of the U-shaped bracket 30 slot 20 with the end of the plate 10, laying the foundation for the subsequent accurate installation of the U-shaped bracket 30.

[0045] II. Precise Depth Control Function of Depth Positioning Component 42: The depth positioning component 42 is installed on the frame 1 and close to the end of the reference positioning component 41, and the positioning plane formed by it is perpendicular to the positioning plane of the reference positioning component 41. This vertical structural design allows the distance between the depth positioning component 42 and the top surface of the plate 10 to be directly converted into precise control of the cutting depth—when the equipment slides to the point where the depth positioning component 42 abuts against the top surface of the plate 10, the cutting automatically stops, ensuring that the depth of each groove is completely uniform. This design solves the problem of large errors caused by manual judgment of cutting depth in traditional construction, and ensures that the U-shaped bracket 30 is strictly lower than the plane of the plate 10 on both sides after installation, completely avoiding the phenomenon of the U-shaped bracket 30 exceeding the plate surface due to inaccurate depth.

[0046] III. Lateral Stabilizing Function of Lateral Positioning Component 43: The lateral positioning component 43 is installed on the frame 1 and located on both sides of the reference positioning component 41. During operation, it clamps the two sides of the plate 10 and slides along the cutting direction. This symmetrical arrangement on both sides provides uniform lateral clamping force to the equipment, effectively limiting the left and right swing of the equipment during the cutting process and ensuring that the milling cutter 2 always cuts along the preset lateral path. At the same time, the positional cooperation between the lateral positioning component 43 and the reference positioning component 41 further enhances the overall fit between the equipment and the plate 10, avoiding skewness or uneven depth on both sides of the groove, ensuring the regularity of the groove shape, and making the U-shaped bracket 30 evenly stressed, stable and reliable after installation.

[0047] IV. The Coordinated Positioning Loop of the Three Components: The reference positioning component 41, depth positioning component 42, and lateral positioning component 43, through assembly with the frame 1, form a three-dimensional positioning loop covering the axial, depth, and lateral dimensions. The axial direction is referenced to the reference positioning component 41, the depth is vertically controlled by the depth positioning component 42, and the lateral direction is symmetrically clamped by the lateral positioning component 43. The cooperation of these three components enhances the adaptability of the directional sliding space 40 to the plate 10. This collaborative mechanism not only ensures the accuracy of single-groove cutting but also significantly improves the consistency of multi-groove cutting, greatly reducing the rework rate caused by groove deviations. Simultaneously, combined with the high-speed cutting of the milling cutter 2, it effectively shortens the single-groove processing time and improves overall construction efficiency.

[0048] In summary, the reference positioning component 41, the depth positioning component 42, and the lateral positioning component 43, through their respective structural designs and assembly relationships with the frame 1, achieve precise positioning of the plate 10 in all directions. This fundamentally solves various problems caused by inaccurate positioning during the installation of the traditional U-shaped bracket 30, providing core support for the efficient and high-quality operation of the grooving machine and demonstrating significant practical value.

[0049] In this embodiment, both the reference positioning element 41 and the depth positioning element 42 are flat plates, but they are not limited to this. For example, a sliding rod can be used to form a positioning plane. The reference positioning element 41 and the depth positioning element 42 can be any structure that can form a positioning plane.

[0050] In this embodiment, the lateral positioning member 43 includes positioning wheels 431, and at least two rotatable positioning wheels 431 are provided on both sides of the reference positioning member 41. The distance between the positioning wheels 431 on one side of the reference positioning member 41 and the positioning wheels 431 on the other side is adapted to the thickness of the plate 10.

[0051] The lateral positioning component 43 also includes a connecting plate 432 and a positioning seat 433. One end of the connecting plate 432 is mounted on the frame 1, and the other end is mounted on the positioning seat 433. Positioning wheels 431 are rotatably mounted on the positioning seats 433. Each positioning wheel 431 corresponds to one positioning seat 433, and each positioning seat 433 corresponds to one connecting plate 432. The connecting plates 432 mounted on one side of the frame 1 are arranged parallel to each other. There is an elastic space between the parallel connecting plates 432. Utilizing the deformable characteristics of this elastic space, the positioning wheels 431 on both sides can adaptively clamp the two sides of the plate 10, ensuring positioning stability.

[0052] The unique design of the lateral positioning component 43 in this invention, through the positioning wheel layout, elastic adaptation structure, and multi-component collaboration, achieves precise, stable, and flexible technical advantages in the grooving positioning of the plate 10, laying a solid foundation for the efficient operation of the grooving machine. The specific beneficial effects are as follows: I. Precise Adaptation to Plate Thickness, Ensuring Consistent Positioning: At least two rotatable positioning wheels 431 are provided on both sides of the reference positioning component 41, and the spacing between the positioning wheels 431 on both sides is adapted to the thickness of the plate 10. During construction, the positioning wheels 431 roll along the surface of the plate 10, utilizing the spacing adaptation characteristic to firmly hold the plate 10 from both sides, preventing the plate 10 from shifting during grooving. Compared to traditional positioning structures without precise spacing design, this ensures a consistent lateral reference for each grooving operation, making the relative height of the groove and the edge of the plate 10 consistent, solving problems such as groove skew and misalignment of the U-shaped bracket 30 caused by inaccurate lateral positioning.

[0053] II. Elastic Adaptive Clamping, Compatible with Different Working Conditions: The lateral positioning component 43 achieves adaptive clamping through the combination of "connecting plate 432 + positioning seat 433 + positioning wheel 431" and the elastic space between the parallel connecting plates 432. When facing plates 10 with slight thickness differences (such as ALC partition wall panel production tolerances), or when the surface of plate 10 has slight unevenness, the elastic space allows the connecting plate 432 to deform slightly, ensuring that the positioning wheel 431 always fits against both sides of plate 10. This ensures stable clamping force, preventing plate 10 from loosening, and avoids damage to plate 10 due to rigid clamping, significantly improving the equipment's adaptability to different construction scenarios and different plates 10, and reducing positioning failure problems caused by differences in plate 10.

[0054] III. Modular Assembly Enhances Structural Stability: The modular design, with one positioning wheel 431 corresponding to one positioning seat 433 and one connecting plate 432, ensures more even force distribution across components. During assembly, the installation accuracy of each positioning wheel can be independently controlled, avoiding cumulative errors caused by excessive component integration. During operation, the modular structure distributes lateral forces across multiple connecting plates and positioning seats, reducing the load on individual components and improving overall structural durability. Compared to integrated, difficult-to-disassemble lateral positioning structures, this design offers easier maintenance, allowing for quick replacement of worn positioning wheels and ensuring long-term stable operation of the equipment.

[0055] IV. Reduced Friction for Smooth Operation: The positioning wheel 431 rolls in contact with the surface of the sheet 10, significantly reducing friction compared to sliding contact methods such as sliders or rigid plates. Operators do not need to overcome significant sliding resistance when pushing the equipment, requiring less effort and allowing for easy control of the grooving rhythm. This is especially beneficial for grooving longer sheets 10, reducing physical exertion and improving construction efficiency. Simultaneously, the less heat generated by rolling friction prevents damage to the surface of the sheet 10 due to frictional heat, ensuring the integrity of the sheet 10.

[0056] In summary, the lateral positioning component 43, through its precisely spaced positioning wheel layout, elastically adaptive clamping structure, modular assembly design, and rolling positioning wheel design, solves the problems of easy lateral positioning deviation, difficulty in adapting to different sheet metals 10, and easy structural damage in traditional grooving machines from four dimensions: positioning accuracy, working condition compatibility, structural stability, and operational smoothness. It provides a stable lateral reference for precise grooving of the milling cutter 2, significantly improving the dimensional consistency and positional accuracy of the U-shaped chuck 30 and slot 20, helping the entire machine achieve efficient and high-quality sheet metal 10 grooving operations, and possessing both practical and economic value (reducing rework rates and extending equipment lifespan).

[0057] It is understood that the lateral positioning member 43 is not limited to the structure described above. For example, the lateral positioning member 43 can use two parallel clamping plates to clamp the two sides of the plate 10. The lateral positioning member 43 can be any structure that can achieve sliding positioning of the two sides of the plate 10.

[0058] In this embodiment, two milling cutters 2 are installed in parallel, and the two milling cutters 2 are used to cut grooves 20 on both sides of the plate 10. The milling cutters 2 adopt a helical cutting head.

[0059] In this embodiment, the milling cutter 2 adopts a double parallel mounting design and is equipped with a spiral cutter head. Working in conjunction with the overall structure of the equipment, it exhibits significant advantages in terms of grooving efficiency, groove quality, and adaptability of the plate 10, as detailed below: I. Simultaneous operation of dual parallel milling cutters significantly improves construction efficiency: Two milling cutters 2 are installed in parallel, allowing for simultaneous cutting of grooves 20 on both sides of the board 10, achieving "one-time advance, double-sided grooving." Compared to the traditional method of using a single milling cutter to groove both sides of the board 10 separately, this eliminates the need for secondary positioning and adjustment, directly halving the grooving time for a single board 10. This is particularly significant in the batch construction of ALC partition boards, significantly shortening the process cycle and improving the overall construction progress. Simultaneous grooving on both sides avoids the problem of groove asymmetry caused by two separate operations, ensuring that the position and depth of the grooves 20 on both sides strictly correspond, providing a foundation for the precise installation of the U-shaped bracket 30.

[0060] II. The spiral-shaped cutter head optimizes cutting performance and ensures groove quality: Smoother cutting and reduced damage to sheet metal 10: The spiral-shaped cutter head has a spiral cutting edge that makes progressive cutting when in contact with sheet metal 10, rather than the instantaneous impact cutting of a straight-edged cutter head. This significantly reduces vibration and impact during the cutting process. For brittle ALC partition boards, this effectively avoids problems such as cracking and chipping of sheet metal 10 caused by impact, ensuring smooth groove edges and reducing subsequent repair work.

[0061] Smooth chip removal, preventing clogging in the groove: The spiral structure forms an axial chip removal channel during rotation, allowing cutting chips to be quickly discharged from the groove along the spiral edge, preventing chip accumulation inside the groove from affecting the continuous cutting of the milling cutter or causing groove deformation due to chip compression. This feature ensures the continuity of the grooving process and further improves construction efficiency.

[0062] The smooth groove wall reduces the difficulty of subsequent processes: The continuous cutting trajectory of the spiral cutter head makes the surface roughness of the groove wall lower. Compared with the rough surface after cutting by the straight cutter head, it is easier to adhere and cure the mortar during subsequent filling, reducing gaps and ensuring the stability of the overall structure after the U-shaped bracket 30 is installed.

[0063] III. Enhanced Overall Adaptability through Collaboration with Positioning and Guiding Devices: The parallel layout of the dual milling cutters precisely matches the lateral positioning components 43 (especially the positioning wheels 431) of the positioning and guiding device 4. The spacing between the two milling cutters matches the clamping distance of the positioning wheels 431, ensuring that the milling cutters are always aligned with the preset cutting position when the positioning wheels guide the device to slide stably along the plate 10, avoiding groove deviation caused by equipment offset. Simultaneously, the low-vibration characteristics of the helical cutter head, in conjunction with the rolling guidance of the positioning wheels, reduce "chatter" during equipment operation, further improving the symmetry and consistency of the double-sided grooving, and providing greater flexibility when adapting to ALC partition boards of different thicknesses and specifications.

[0064] In summary, the dual parallel mounting design and helical cutter head structure of the milling cutter 2 solve the problems of low efficiency, poor groove shape, and easy damage to the plate 10 that exist in traditional single-cut and straight-edged cutter heads in terms of efficiency, quality, and adaptability. It works in conjunction with other components of the equipment to achieve efficient, accurate, and stable grooving of the plate 10, and provides key guarantees for the concealed installation of the U-shaped bracket 30 and the smooth progress of subsequent processes, which has significant practical value.

[0065] In this embodiment, the drive mechanism 3 uses two motors, each connected to a milling cutter 2. Each milling cutter 2 is driven by an independent motor, ensuring that both milling cutters receive balanced and stable power. Compared to a single motor driving two milling cutters simultaneously via a transmission mechanism (such as gears or belts), this design avoids differences in milling cutter speeds caused by uneven transmission losses—wear or loosening of transmission components on one side will not affect the operation of the milling cutter on the other side. This characteristic ensures that the cutting speed and cutting force of the slots 20 on both sides of the plate 10 are completely consistent, resulting in highly uniform dimensional parameters such as slot depth and width. It also prevents the slots on one side from being too shallow, too wide, or rough due to uneven power, providing a precise dimensional basis for the symmetrical installation of the U-shaped bracket 30. The dual motors driving the dual milling cutters provide sufficient and continuous power to each helical cutter head, ensuring cutting stability during high-speed rotation. The progressive cutting of the helical cutter head requires stable speed support, and the independent motors can avoid speed fluctuations caused by load changes (such as cutting into hard impurities inside the plate 10), ensuring smooth chip removal and smooth slot walls. This "dual-motor + dual-milling-cutter" matching design enables the stable realization of the efficient operation mode of "one-time advance, double-sided grooving," further improving construction efficiency. It can be understood that the drive mechanism 3 could also use a single motor to synchronously drive the two milling cutters 2 through a transmission mechanism.

[0066] The grooving machine of the present invention also includes a power supply device, which is a battery 5 that supplies power to the drive mechanism 3. The battery 5 and the positioning guide device 4 are respectively installed on the two side surfaces of the frame 1. The battery 5 is provided with a charging interface. A switch 6 for controlling the start and stop of the drive mechanism 3 is installed on the circuit connecting the battery 5 and the drive mechanism 3. Alternatively, the power supply device can also directly supply power using a power cord and plug.

[0067] The grooving machine of the present invention also includes two handles 7 installed at both ends of the frame 1. Cutting and grooving are achieved by holding the two handles 7 with both hands and pushing the grooving machine to move.

[0068] The grooving machine of this invention has two handles 7 at both ends of the frame 1, allowing the operator to hold them with both hands and push the equipment to move it for cutting and grooving. This design works synergistically with the overall machine structure, demonstrating significant advantages in terms of ease of operation, force application stability, and safety, as detailed below: I. Enhanced Operational Stability and Precision through Coordinated Two-Handed Operation: Two handles 7 are installed at both ends of the frame 1, allowing operators to maintain stable control of the equipment by gripping them with both hands. When pushing the grooving machine, applying force with both hands enables more precise control of the machine's speed and direction, preventing tilting or deviation caused by single-handed operation. Especially when grooving along the length of the plate 10, balanced force from both hands ensures that the machine moves smoothly in a straight line. Combined with the directional guidance of the positioning guide device 4, the milling cutter 2 can cut strictly according to the preset path, further ensuring the straightness and positional accuracy of the groove and reducing groove deviation caused by unstable operation.

[0069] II. Ergonomic Design Reduces Operator Fatigue: The two-handed grip on both ends of the handle 7 aligns with the body's natural force application habits, distributing force across the hands and arms, avoiding excessive load on a single limb when operating with one hand. During prolonged, batch grooving operations, this effectively reduces muscle fatigue, extends continuous working time, and improves overall construction efficiency. Simultaneously, the optimized handle spacing and placement allow operators to maintain a comfortable operating posture, reducing operational errors caused by improper posture and ensuring efficient and stable construction.

[0070] III. Enhanced Safety Performance Through Integration with the Overall Machine Structure: Two handles 7 are installed at both ends of the frame 1. During operation, the operator's hands maintain a safe distance from high-speed rotating components such as the milling cutter 2, reducing the risk of accidental contact. Simultaneously, the two-hand grip enhances the operator's control over the equipment. In the event of emergencies (such as abnormalities in the sheet metal 10 or increased equipment vibration), a counterforce can be quickly applied to stop the equipment, preventing accidents or equipment damage and improving operational safety.

[0071] In summary, the two handles 7 installed at both ends of the frame 1 improve operational stability and accuracy by applying force with both hands, conform to ergonomics to reduce operator fatigue, and enhance safety performance in conjunction with the overall machine structure.

[0072] In this embodiment, please refer to the relevant documentation. Figure 6 The frame 1 includes two cover plates 11 and two upright plates 12. A space is formed between the two cover plates 11 to accommodate the drive mechanism 3, and the two cover plates 11 clamp and fix the drive mechanism 3. The two upright plates 12 are respectively vertically installed at both ends of the two cover plates 11, forming a "U"-shaped structure. Two handles 7 are respectively installed on the outer sides of the two upright plates 12. A connecting plate 432 is installed on the inner side of the two upright plates 12. A reference positioning component 41 is installed on the two cover plates 11. A depth positioning component 42 is installed between the tops of the two upright plates 12.

[0073] The frame 1 adopts a combination structure of two cover plates 11 and two upright plates 12. Through scientific layout design, it provides a stable installation foundation for all components of the grooving machine, and at the same time, it shows significant advantages in terms of structural strength, space utilization and collaborative operation, as detailed below: 1. The combination of cover plates and upright plates enhances structural stability and ensures reliable equipment operation: Two cover plates 11 and two upright plates 12 form a U-shaped structure. This highly enclosed frame design significantly improves the overall rigidity of the frame 1. Compared to a frame formed by bending a single sheet of material 10, the U-shaped structure can more evenly distribute the vibration and impact forces generated during equipment operation. Especially when the drive mechanism 3 drives the milling cutter 2 to rotate and cut at high speed, it can effectively prevent deformation or shaking of the frame 1, providing solid support for the stable operation of each component. At the same time, the upright plates 12 are vertically installed at both ends of the cover plates 11, further enhancing the torsional resistance of the structure and ensuring that the equipment can maintain good structural accuracy even after long-term high-intensity operation.

[0074] II. Optimizing spatial layout and improving the rationality and compactness of component installation: The space formed between the two cover plates 11 is specifically used to accommodate the drive mechanism 3, and the drive mechanism 3 is positioned by clamping and fixing, which not only ensures that the drive mechanism 3 is firmly installed, but also avoids the need for additional fasteners to occupy too much space, making the connection between the drive mechanism 3 and the milling cutter 2 more direct and reducing power transmission losses. The two upright plates 12 serve as the mounting carriers for the handle 7 and the connecting plate 432, respectively. The handle 7 is installed on the outside for easy gripping by the operator, while the connecting plate 432 is installed on the inside to bring the lateral positioning component 43 closer to the plate 10, improving positioning accuracy. In addition, the reference positioning component 41 is installed on the two cover plates 11 as a whole, and the depth positioning component 42 is installed between the tops of the two upright plates 12. The components are rationally distributed around the core working area, making the overall structure compact, reducing unnecessary space waste, and facilitating flexible movement of the equipment in narrow construction scenarios.

[0075] III. Closer Coordination of Components Enhances Overall Machine Efficiency: The structural design of the frame 1 creates favorable conditions for the coordinated operation of all components. The drive mechanism 3 is stably clamped by the cover plate 11, ensuring it can provide continuous and stable power to the milling cutter 2; the depth positioning component 42 at the top of the upright plate 12 can precisely limit the cutting depth, and cooperates with the reference positioning component 41 on the cover plate 11 to form a complete positioning system; the lateral positioning component 43 connected to the connecting plate 432 on the inner side of the upright plate 12 can stably clamp the plate 10 from both sides, and when the handle 7 pushes the equipment to move, the milling cutter 2 cuts strictly according to the positioning guide. This orderly layout of the components on the frame 1 makes the power output, positioning guide, operation control and other functions of the equipment form an organic whole, greatly improving the overall operating accuracy and efficiency of the machine.

[0076] Fourth, it facilitates production, manufacturing, and maintenance, and reduces costs: The simple structure of the two cover plates 11 and the two upright plates 12 makes them easy to process and manufacture. Standardized production can improve production efficiency and reduce manufacturing costs. At the same time, the installation positions of each component on the frame 1 are clear, making disassembly and replacement convenient. When a component malfunctions, there is no need to disassemble the entire frame 1, allowing for quick repair or replacement, reducing equipment downtime and maintenance costs.

[0077] In summary, the frame 1, through the rational combination of two cover plates 11 and two upright plates 12, not only possesses excellent structural stability and space utilization, but also promotes close collaboration among various components, while facilitating production, manufacturing, and maintenance. This structural design provides crucial support for the grooving machine to achieve efficient, precise, and stable operation. Working together with components such as the drive mechanism 3, milling cutter 2, positioning and guiding device 4, and handle 7, it further enhances the overall performance and practical value of the equipment.

[0078] The grooving machine provided by this invention can accurately groove the board 10 (such as ALC partition board). Its grooving method is based on the synergistic effect of various components of the equipment. The specific steps are as follows: 1. Start the drive mechanism 3 to drive the milling cutter 2 to rotate at high speed, providing power for cutting and grooving. At this time, the two milling cutters 2 rotate synchronously, ready to carry out the cutting operation.

[0079] 2. The operator holds the grooving machine with both hands and places the positioning guide device 4 onto the cutting start position of the plate 10, aligning the milling cutter 2 with the cutting start position on the plate 10. The specific positioning process of the positioning guide device 4 is as follows: Reference positioning: Adjust the position of the grooving machine so that the reference positioning part 41 of the positioning guide device 4 fits against the end face of the plate 10, and use this as the axial positioning reference to ensure that the cutting position of the milling cutter 2 and the relative position of the end of the plate 10 meet the preset requirements.

[0080] Lateral positioning: Operate the grooving machine so that the positioning wheels 431 of the lateral positioning component 43 of the positioning guide device 4 contact the two side surfaces of the plate 10. Since the connecting plates 432 of the lateral positioning component 43 are arranged in parallel and have elastic space between them, the positioning wheels 431 will adaptively clamp the two sides of the plate 10. Utilizing their rotatable characteristics, they provide stable lateral guidance for the equipment to slide along the plate 10, preventing the equipment from shifting laterally during the cutting process.

[0081] 3. The operator slowly pushes the grooving machine, moving it along the grooving depth direction of the plate 10. During the movement, the high-speed rotating milling cutter 2 begins to contact the plate 10 and cut.

[0082] 4. As the equipment moves, the depth positioning component 42 of the positioning guide device 4 gradually approaches the top surface of the plate 10. When the depth positioning component 42 abuts against the top surface of the plate 10, it indicates that the milling cutter 2 has cut to the preset depth, and the operator stops pushing the equipment.

[0083] 5. Turn off the drive mechanism 3 to stop the milling cutter 2 from rotating, and remove the grooving machine from the plate 10 to complete one grooving operation. At this time, a slot 20 that meets the size requirements has been cut into the plate 10.

[0084] By using the above-mentioned grooving method, the grooving machine frame 1, milling cutter 2, drive mechanism 3 and positioning guide device 4 work together to quickly and accurately cut slots 20 on the plate 10, which facilitates the subsequent installation of U-shaped brackets 30 and effectively improves construction efficiency and quality.

[0085] The grooving machine of the present invention achieves precise grooving of the board 10 (such as ALC partition board) through the coordinated operation of components such as the frame 1, milling cutter 2, drive mechanism 3, positioning and guiding device 4, and handle 7. The specific working principle is as follows: Before starting the equipment, the plate 10 to be processed must be placed stably to ensure that there are no obvious protrusions or impurities on its surface. At this time, the "U"-shaped structure of the frame 1 provides stable support for each component. The drive mechanism 3 (two motors) clamped and fixed between the two cover plates 11 is in the ready-to-start state. The two milling cutters 2 (spiral cutter heads) connected to it are not in contact with the plate 10. Each component of the positioning guide device 4 is in the initial position: the reference positioning component 41 has not yet been attached to the end face of the plate 10, the depth positioning component 42 maintains a certain distance from the top surface of the plate 10 (this distance is preset to the required cutting depth), and the positioning wheel 431 of the lateral positioning component 43 is not in contact with the sides of the plate 10. After the equipment is started, the two motors of the drive mechanism 3 operate synchronously, driving the corresponding milling cutters 2 to rotate at high speed, providing power for cutting and grooving. The operator holds the handles 7 installed on the outside of the upright plates 12 at both ends of the frame 1, aligns the equipment with the position to be grooved on the plate 10, and makes the reference positioning component 41 of the positioning guide device 4 fit against the end face of the plate 10, which serves as the axial positioning reference. Then, the position of the equipment is adjusted so that the positioning wheels 431 of the lateral positioning component 43 contact the two side surfaces of the plate 10. Due to the elastic space between the parallel connecting plates 432, the positioning wheels 431 will adaptively clamp the plate 10, using their rotatable characteristics to ensure that the equipment can slide smoothly along the surface of the plate 10, while restricting the equipment offset from the side. As the operator pushes handle 7 to move the equipment along the length of the plate 10, the high-speed rotating milling cutter 2 begins to contact the plate 10 and cut. At this time, the reference positioning component 41 slides against the end face of the plate 10 to ensure that the cutting position of the milling cutter 2 is always consistent with the relative position of the end of the plate 10; the positioning wheels 431 of the lateral positioning component 43 roll along both sides of the plate 10, and with the elastic clamping force, prevent the equipment from shifting laterally during the sliding process, ensuring that the milling cutter 2 cuts along the preset lateral path; the depth positioning component 42 gradually approaches the top surface of the plate 10 as the equipment moves. When the depth positioning component 42 abuts against the top surface of the plate 10, it indicates that the milling cutter 2 has cut to the preset depth, and the operator stops pushing the equipment, completing one grooving operation. During this process, the helical milling cutter 2, while rotating at high speed, reduces the impact on the plate 10 through progressive cutting. At the same time, the helical structure discharges the cutting debris axially, preventing blockage in the groove. The two milling cutters 2 operate in parallel, simultaneously cutting grooves 20 on both sides of the plate 10, achieving "one-time advance, double-sided grooving". The cover plate 11 and the upright plate 12 of the frame 1 provide stable structural support to ensure that the drive mechanism 3, the milling cutter 2, and the positioning guide device 4 do not shake or deform during the cutting process, ensuring the precision of the coordinated operation of each component. Finally, through the orderly operation of the above components, the grooving machine cuts out a slot 20 on the plate 10 that meets the size requirements (depth, width, and precise position), providing a suitable slot for the subsequent installation of the U-shaped bracket 30 and meeting the construction needs.
