Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and in particular to a grooving device for prefabricated building components. Background Technology

[0002] The field of construction equipment technology encompasses various types of machinery and tools used on construction sites. Its core content lies in improving efficiency and precision control during the construction process through mechanization. This field systematically covers equipment for the entire process, from earthwork excavation and structural component processing to decoration and installation. Structural component processing focuses on the prefabrication and reprocessing of building components, involving specific processes such as cutting, grooving, and drilling to ensure that the components meet the dimensional and fit requirements of prefabricated buildings.

[0003] Among them, the prefabricated building component grooving device refers to a specialized piece of equipment used for grooving precast concrete or metal components. The technical issues addressed by this device include rapid positioning and clamping of components, precise adjustment of grooving dimensions, and maintenance of stability during the processing. Specific solutions include using adjustable clamps and a worktable to fix the components, driving a saw blade or milling cutter to perform rotary cutting via an electric motor, and controlling the lateral and longitudinal movement of the cutter using linear guides and a lead screw mechanism.

[0004] Existing adjustable clamps are difficult to adapt flexibly to plates of different widths, and the limiting fit is insufficient, resulting in deviations in the grooving position; the linear guide rail and lead screw mechanism have poor power stability during transmission, the plate is prone to shaking during grooving, and the impact force during grooving is large, which can easily lead to differences in grooving position and quality, and cannot meet the usage requirements of prefabricated building components for grooving accuracy and quality. Summary of the Invention

[0005] The main objective of this invention is to provide a grooving device for prefabricated building components, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A grooving device for prefabricated building components includes a processing table, a shielding cabinet disposed on the upper part of the processing table, a cabinet door disposed on the front side of the shielding cabinet, a support platform for supporting the board material disposed on the upper part of the processing table, a grooving structure for grooving the board material disposed on the upper part of the support platform, and a guide drive structure for guiding the grooving structure to move parallel to the board material disposed on the upper part of the support platform.

[0007] Preferably, the support platforms are symmetrically distributed on the left and right, and their inner cavities are rotatably connected to threaded rods driven by motors. Several support tubes are rotatably connected to one end of the two support platforms that are close to each other. The outer surface of each of the support tubes is fitted with a limiting member that is fixedly connected to the adjacent support platform.

[0008] Preferably, the limiting member includes a sliding tube sleeved on the outer surface of the support tube, and a compression spring fixedly connected to an adjacent support plate at one end of the sliding tube near the same side support plate. The inner wall of the sliding tube is provided with a rubber ring whose inner wall fits against the outer wall of the support tube.

[0009] Preferably, the guiding drive structure includes support plates symmetrically distributed on the left and right and slidably connected to the upper ends of adjacent support platforms. Each of the two support plates has a slider fixedly connected to the lower end, which is slidably connected to the inner cavity of the adjacent support platform and threadedly connected to a threaded rod. A second guide groove is fixedly connected to the upper part of one end of each of the two support plates that is close to each other, and a first guide groove is fixedly connected to the lower part of one end of each of the two support plates that is close to each other. The inner walls of both the second and first guide grooves are slidably connected to the slotted structure. An electric slide rail is provided at the upper end of the second guide groove and fixedly connected to the two side support plates. A connecting rod fixedly connected to the slotted structure is fixedly connected to the movable side of the electric slide rail.

[0010] Preferably, a second protrusion is fixedly connected to the top wall of the inner surface of the second guide groove, and a first protrusion is fixedly connected to the bottom wall of the inner surface of the first guide groove. Both the second and first protrusions are trapezoidal and have the same height. The midpoints of the paths of the first and second protrusions are on the same vertical line, but the width of the first protrusion is equal to the width of the second protrusion.

[0011] Preferably, the grooving structure includes a sliding block that is fixedly connected to the connecting rod and slidably connected to the inner wall of guide groove one and guide groove two. The upper and lower ends of the sliding block are symmetrically provided with driven components that are in close contact with adjacent protrusion two and protrusion one. The upper and lower ends of the sliding block are symmetrically rotatably connected with rollers that are slidably connected to the inner wall of guide groove two and guide groove one. The upper part of the outer surface of the sliding block is provided with a grooving component for grooving, and the lower part of the outer surface of the sliding block is provided with a limiting component that limits the plate by pressing.

[0012] Preferably, the driven component includes a contact wheel that is slidably connected to the inner surface of the sliding block via a spring. The contact wheel is in close contact with the inner wall of the adjacent guide groove one or guide groove two. The inner cavity of the sliding block has a hydraulic chamber. A piston rod that is slidably connected to the inner wall of the hydraulic chamber is fixedly connected to the side of the contact wheel near the hydraulic chamber. A spring plate one is slidably connected to the side of the inner wall of the hydraulic chamber away from the piston rod via a spring. Both ends of the spring plate one are fixedly connected to driven plates that are slidably connected to the inner cavity of the sliding block. When the driven plates are at the uppermost and lowermost positions, the inner cavity of the hydraulic chamber is always not in communication with the outer wall of the sliding block. The driven plate at the upper position is fixedly connected to the slotting component, and the driven plate at the lower position is fixedly connected to the limiting component. When the contact wheel contacts the protrusion one or protrusion two, the contact wheel retracts into the inner cavity of the sliding block and drives the spring plate one and the driven plate to slide towards the center of the sliding block through hydraulic action.

[0013] Preferably, the limiting component includes symmetrically formed grooves on the lower part of the outer surface of the sliding block. Sliding rods are slidably connected to the inner walls of the two grooves. Cables are fixedly connected to the adjacent driven plates at the ends of the two sliding rods near the adjacent driven plates. Connecting blocks are fixedly connected to the lower ends of the two sliding rods. Spring plates are slidably connected to the inner walls of the two connecting blocks via springs. Limiting wheels extending through the inner cavity of the connecting blocks and reaching the lower ends of the connecting blocks are symmetrically fixed to the lower ends of the two spring plates.

[0014] Preferably, the connecting block has a limiting groove on the side near the center of the sliding block to limit the sliding path of the slotting assembly. The inner wall of the limiting groove is provided with a limiting rod, and the outer surface of the limiting rod is fitted with a compression spring. When the contact wheel at the lower part contacts the protrusion, it drives the driven plate to move upward and pulls the sliding rod downward through the cable. When the driven plate at the lower part resets, the sliding rod resets under the action of the compression spring and the slotting assembly.

[0015] Preferably, the grooving assembly includes a mounting block slidably connected to an adjacent limiting groove. The lower end of the mounting block has a mounting groove, and several sanding discs are rotatably mounted in an array on the inner wall of the mounting groove. These sanding discs are inclined, with their mounting height decreasing sequentially from left to right. An electric motor that drives the sanding discs to rotate is installed inside the mounting block. U-shaped plates are fixedly connected to both ends of the mounting block, and two U-shaped plates are jointly fixedly connected to a T-shaped rod that is fixedly connected to the driven plate located at the upper part. When the upper contact wheel contacts the second protrusion, it drives the driven plate downwards, and through the T-shaped rod and U-shaped plates, drives the mounting block downwards, causing the sanding discs to contact the plate material for grooving.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a support tube on a support platform to stably support the sheet metal and reduce friction. The limiting component on its outer surface, through the cooperation of a sliding tube and a compression spring, can adaptively adjust the limiting distance according to the width of the sheet metal. In conjunction with the rubber ring on the inner wall of the sliding tube, it enhances the fit and prevents dust and deviation, thereby improving the limiting stability and the service life of the component. Furthermore, through the cooperation of a threaded rod and a guide drive structure, the position of the guide drive structure can be adjusted to adapt to sheet metal of different widths, providing stable guidance for the grooving structure. The three work together to avoid the sheet metal from shifting and shaking during operation, and to ensure a smooth and orderly grooving process, meeting the grooving requirements of prefabricated building components.

[0017] 2. This invention uses the cooperation of a threaded rod, a slider, and a support plate to drive the guide groove one and guide groove two to adjust their positions to adapt to plates of different widths; the protrusion one and protrusion two adopt a trapezoidal structure, and the width of protrusion one is % of that of protrusion two. This design can smoothly trigger the grooving structure action, avoid the components being subjected to force impact, and at the same time realize the plate is fixed before the grooving operation, preventing the plate displacement from affecting the grooving consistency and ensuring the cut is neat.

[0018] 3. This invention optimizes the grooving effect and ensures the quality of operation by coordinating the grooving structure and the guiding drive structure. Specifically, the driven component ensures smooth and uniform power transmission through the hydraulic chamber and piston rod, providing stable support for grooving operations; the limiting component's limiting wheel, in conjunction with the spring plate, applies pressure to stabilize the limiting plate while avoiding damage, preventing the plate from shaking or shifting, and ensuring consistent grooving position; the grooving component's abrasive blades are distributed with decreasing inclination to reduce cutting impact, minimize plate damage, effectively prevent edge chipping and cracking, and improve the smoothness of the grooving cut. All components work together to ensure grooving quality and stability. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: A grooving device for prefabricated building components, see reference. Figure 1 and Figure 2 The system includes a processing table 1, a shielding cabinet 3 located on top of the processing table 1, and a cabinet door 6 located on the front side of the shielding cabinet 3. The processing table 1 has a support platform 2 for supporting the sheet metal, and the support platform 2 has a grooving structure 5 for grooving the sheet metal. The support platform 2 also has a guide drive structure 4 for guiding the grooving structure 5 to move parallel. The processing table 1 provides a stable support foundation for the entire device, ensuring the overall stability of each component during operation. The shielding cabinet 3 can effectively isolate the dust and noise generated during grooving operations, reducing the impact on the surrounding environment and operators. The cabinet door 6 allows operators to easily pick up and put down the sheet metal to be processed and to perform daily maintenance and repair on the internal components. The support platform 2 provides dedicated support space for the sheet metal, and the guide drive structure 4 guides the grooving structure 5 to move stably, ensuring that the grooving position meets expectations.

[0023] For further details, please refer to [link / reference]. Figure 2 and Figure 3The support platforms 2 are symmetrically distributed on both sides, and their inner cavities are rotatably connected to threaded rods 23 driven by motors. At the ends of the two support platforms 2 that are close to each other, several support tubes 21 are rotatably connected in an array. The outer surface of each support tube 21 is fitted with a limiting member 22 that is fixedly connected to the adjacent support platform 2. When the threaded rods 23 are rotated by the motor, they can provide power for the movement of the guide drive structure 4. The symmetrical support platforms 2 can ensure balanced force and improve the stability of the device operation. The array of support tubes 21 can provide stable support for the plate, and the support tubes 21 can rotate synchronously with the movement of the plate, effectively reducing the frictional resistance between the plate and the support structure, facilitating the placement and fine adjustment of the plate position. The limiting member 22 can elastically limit the two sides of the plate to prevent the plate from shifting laterally during operation.

[0024] For further details, please refer to [link / reference]. Figure 3 The limiting component 22 includes a sliding tube 221 sleeved on the outer surface of the support tube 21. One end of the sliding tube 221 near the support platform 2 on the same side is fixedly connected to a compression spring 222 fixedly connected to the adjacent support platform 2. A rubber ring is provided on the inner wall of the sliding tube 221, and the inner wall of the rubber ring is in contact with the outer wall of the support tube 21. The sliding tube 221 can slide along the axial direction of the support tube 21. With the elastic force of the compression spring 222, the limiting distance can be adaptively adjusted according to the width of the plate, adapting to the limiting requirements of different specifications of plates. The rubber ring can not only enhance the tightness of the contact between the sliding tube 221 and the outer wall of the support tube 21, preventing the sliding tube 221 from shifting and shaking during movement, but also play a good dustproof role, preventing the grooved dust from entering the gap between the two and affecting the flexible operation of the component, improving the limiting stability and the service life of the component.

[0025] During operation in this embodiment, the support tube 21 on the support platform 2 can stably support the plate and reduce friction. The limiting member 22 on its outer surface can adaptively adjust the limiting distance according to the width of the plate through the cooperation of the sliding tube 221 and the compression spring 222. In conjunction with the rubber ring on the inner wall of the sliding tube 221, the fit is enhanced and dustproof and offset prevention is provided, thereby improving the limiting stability and the service life of the component. Furthermore, through the cooperation of the threaded rod 23 and the guide drive structure 4, the position of the guide drive structure 4 can be adjusted to adapt to plates of different widths, providing stable guidance for the grooving structure 5. The three work together to avoid the plate from shifting and shaking during operation, and to ensure that the grooving process is smooth and orderly, meeting the grooving requirements of prefabricated building components.

[0026] In Example 2, based on Example 1, the threaded rod 23, slider 42 and support plate 41 work together to adjust the position of guide groove 1 43 and guide groove 2 44 to adapt to plates of different widths. The protrusions 1 431 and 2 441 adopt a trapezoidal structure, and the width of protrusion 1 431 is 90% of that of protrusion 2 441. This design can smoothly trigger the action of the grooving structure 5, avoid the impact of force on the parts, and at the same time realize the plate is fixed before the grooving operation, prevent the plate displacement from affecting the grooving consistency and ensure the cut is neat.

[0027] For further details, please refer to [link / reference]. Figure 4 The guide drive structure 4 includes support plates 41 symmetrically distributed on the left and right and slidably connected to the upper ends of adjacent support platforms 2. Each support plate 41 has a slider 42 fixedly connected to its lower end, which is slidably connected to the inner cavity of the adjacent support platform 2 and threadedly connected to a threaded rod 23. A second guide groove 44 is fixedly connected to the upper part of one end of the two support plates 41 that is close to each other, and a first guide groove 43 is fixedly connected to the lower part of one end of the two support plates 41 that is close to each other. The inner walls of both the second guide groove 44 and the first guide groove 43 are slidably connected to the slotted structure 5. An electric slide rail 46 is fixedly connected to the upper end of the second guide groove 44 and to the two side support plates 41. The movable side of the electric slide rail 46 is fixedly connected to... The connecting rod 45, which is fixedly connected to the slotted structure 5, drives the slider 42 to slide in the inner cavity of the support platform 2 through the threaded engagement when the threaded rod 23 rotates. This, in turn, drives the support plate 41 to move smoothly along the upper end of the support platform 2, thereby adjusting the position of the guide groove 1 43 and the guide groove 2 44 to adapt to the slotting requirements of different width plates. The threaded engagement between the slider 42 and the threaded rod 23 can achieve accurate alignment, ensuring the movement effect of the guide structure. The guide groove 1 43 and the guide groove 2 44 provide bidirectional sliding guidance for the slotted structure 5. After the electric slide rail 46 is started, it drives the slotted structure 5 to slide smoothly along the guide groove through the connecting rod 45, providing stable lateral power for the slotting operation.

[0028] For further details, please refer to [link / reference]. Figure 5 and Figure 6 A second protrusion 441 is fixedly connected to the top wall of the inner surface of the second guide groove 44, and a first protrusion 431 is fixedly connected to the bottom wall of the inner surface of the first guide groove 43. Both the second protrusion 441 and the first protrusion 431 are trapezoidal and have the same height. The midpoint of the paths of the first protrusion 431 and the second protrusion 441 are on the same vertical line, but the width of the first protrusion 431 is 90% of the width of the second protrusion 441. The trapezoidal protrusions can make the driven component 53 on the slotting structure 5 make smooth contact and gradually trigger the action, avoiding damage to the component due to instantaneous force impact. The same height of the two can ensure that the stroke of the limiting action and the slotting action are matched, ensuring that the action amplitude is coordinated and consistent. The width difference design can realize that the limiting action starts before the slotting action. After the plate is stabilized and limited, the slotting operation is carried out, which improves the slotting effect and avoids displacement of the plate due to incomplete fixation.

[0029] For further details, please refer to [link / reference]. Figure 6 The grooving structure 5 includes a sliding block 51 fixedly connected to the connecting rod 45 and slidably connected to the inner walls of guide groove 1 43 and guide groove 2 44. The upper and lower ends of the sliding block 51 are symmetrically provided with driven components 53 that are in close contact with adjacent protrusions 2 441 and 1 431. The upper and lower ends of the sliding block 51 are symmetrically rotatably connected with rollers 52 that are slidably connected to the inner walls of guide groove 2 44 and guide groove 1 43. The upper part of the outer surface of the sliding block 51 is provided with a grooving component 54 for grooving, and the lower part of the outer surface of the sliding block 51 is provided with a mechanism for pressing the plate. The limiting component 55, which performs the limiting function, and the sliding block 51, which is the core load-bearing component of the grooving structure 5, reduce friction loss and improve the smoothness of sliding by sliding along the guide groove through the roller 52, and avoid jamming that affects the grooving effect. The left and right symmetrical rollers 52 can ensure that the sliding block 51 is subjected to balanced force and prevent tilting during the sliding process. The driven component 53 can sense the position of the protrusion and trigger subsequent limiting and grooving actions to achieve orderly linkage between the two. The limiting component 55 is responsible for pressing and fixing the plate during operation, and the grooving component 54 undertakes the specific cutting and grooving tasks.

[0030] Example 3: Based on Example 2, this example further optimizes the grooving effect and ensures the quality of operation by coordinating the grooving structure 5 and the guiding drive structure 4. Specifically, the driven component 53 ensures smooth and uniform power transmission through the hydraulic chamber 532 and the piston rod 533, providing stable support for the grooving operation; the limiting wheel 558 of the limiting component 55, together with the spring plate 557, applies pressure to stabilize the limiting plate while avoiding crushing, preventing the plate from shaking or shifting, and ensuring the consistency of the grooving position; the sanding blades 545 of the grooving component 54 are distributed with decreasing inclination to reduce the cutting impact force, reduce plate damage, effectively avoid edge chipping and cracking, and improve the smoothness of the grooving cut. All components work together to ensure the quality and stability of the grooving.

[0031] For further details, please refer to [link / reference]. Figure 7The driven component 53 includes a contact wheel 531 that is slidably connected to the inner surface of the sliding block 51 via a spring. The contact wheel 531 is in close contact with the inner wall of the adjacent guide groove 43 or guide groove 44. A hydraulic chamber 532 is formed in the inner cavity of the sliding block 51. A piston rod 533 that is slidably connected to the inner wall of the hydraulic chamber 532 is fixedly connected to the side of the contact wheel 531 near the hydraulic chamber 532. A spring plate 534 is slidably connected to the side of the inner wall of the hydraulic chamber 532 away from the piston rod 533 via a spring. Both ends of the spring plate 534 are fixedly connected to driven plates 535 that are slidably connected to the inner cavity of the sliding block 51. When the driven plates 535 are at the uppermost and lowermost positions, the inner cavity of the hydraulic chamber 532 is always not in communication with the outer wall of the sliding block 51. The driven plate 535 at the upper position is fixedly connected to the slotted component 54, and the driven plate 535 at the lower position is fixedly connected to the slotted component 54. The moving plate 535 is fixedly connected to the limiting component 55. When the contact wheel 531 contacts the first protrusion 431 or the second protrusion 441, the contact wheel 531 retracts into the inner cavity of the sliding block 51 and drives the first spring plate 534 and the driven plate 535 to slide towards the center of the sliding block 51 through hydraulic action. The contact wheel 531 is always in close contact with the inner wall of the guide groove through the spring, ensuring that the position of the protrusion can be sensed in time. The hydraulic transmission method can ensure smooth and uniform power transmission and avoid action jamming or impact. The spring on the first spring plate 534 can assist the driven component 53 in resetting and improve the stability of repeated use of the component. The design of the hydraulic cavity 532 not being connected to the outside can prevent hydraulic oil leakage and avoid affecting the operation of the equipment and the working environment. The upper and lower driven plates 535 are linked to the slotting component 54 and the limiting component 55 respectively to achieve synchronous coordination of actions.

[0032] For further details, please refer to [link / reference]. Figure 8 and Figure 9 The limiting component 55 includes symmetrically arranged grooves 554 on the lower part of the outer surface of the sliding block 51. Sliding rods 551 are slidably connected to the inner walls of both grooves 554. Cables 552, which are fixedly connected to the adjacent driven plate 535, are fixedly connected to the ends of both sliding rods 551 near the adjacent driven plate 535. Connecting blocks 553 are fixedly connected to the lower ends of both sliding rods 551. Spring plates 557 are slidably connected to the inner walls of both connecting blocks 553 via springs. Symmetrically fixed to the lower ends of the two spring plates 557 are laterally connected to the inner cavities of the connecting blocks 553, extending to the lower ends of the connecting blocks 553. The limiting wheel 558 and the slide groove 554 provide stable sliding guidance for the sliding rod 551, ensuring that the sliding rod 551 moves up and down without deviation. When the driven plate 535 moves, the sliding rod 551 is pulled by the cable 552, which drives the connecting block 553 to move synchronously. The limiting wheel 558 contacts the surface of the plate and applies pressure to achieve the limiting. The spring of the spring plate 557 can provide buffer pressure to avoid excessive pressure from damaging the surface of the plate, while ensuring the firmness of the limiting of the plate and preventing the plate from shaking up and down during the grooving process. The left and right symmetrical limiting wheels 558 can make the plate evenly stressed, further improving the limiting stability.

[0033] For further details, please refer to [link / reference]. Figure 9 The connecting block 553 has a limiting groove 555 on the side near the center of the sliding block 51 to limit the sliding path of the grooving assembly 54. A limiting rod is provided on the inner wall of the limiting groove 555, and a compression spring 556 is sleeved on the outer surface of the limiting rod. When the contact wheel 531 at the lower part contacts the protrusion 431, it drives the driven plate 535 to move upward and pulls the sliding rod 551 downward through the cable 552. When the driven plate 535 at the lower part resets, the sliding rod 551 resets under the action of the compression spring 556 and the grooving assembly 54. The limiting groove 555 and the limiting rod can effectively limit the sliding path of the grooving assembly 54 and prevent the grooving assembly 54 from deviating and affecting the grooving effect. The compression spring 556 can provide elastic reset force to ensure that the sliding rod 551 quickly returns to the initial position after the driven plate 535 resets, preparing for the next operation. At the same time, it can improve the smoothness of the reset action in conjunction with the grooving assembly 54, avoid component jamming, and ensure the continuity of the operation process.

[0034] For further details, please refer to [link / reference]. Figure 9 and Figure 10 The slotted assembly 54 includes a mounting block 543 slidably connected to an adjacent limiting groove 555. A mounting groove 544 is formed at the lower end of the mounting block 543. A plurality of sanding discs 545 are rotatably mounted in an array on the inner wall of the mounting groove 544. The sanding discs 545 are inclined and their mounting height decreases sequentially from left to right. An electric motor is installed inside the mounting block 543 to drive the sanding discs 545 to rotate. U-shaped plates 542 are fixedly connected to both ends of the mounting block 543. The two U-shaped plates 542 are jointly fixedly connected to a T-shaped rod 541 fixedly connected to the upper driven plate 535. When the upper contact wheel 531 contacts the second protrusion 441, it drives the driven plate 535 to move downwards and through the T-shaped rod. The U-shaped plate 541 and U-shaped plate 542 drive the mounting block 543 to move downwards, causing the sanding disc 545 to contact the plate for grooving. The mounting block 543 provides a stable mounting carrier for the sanding disc 545 and the motor. The U-shaped plate 542 and T-shaped rod 541 ensure that the power of the driven plate 535 is smoothly transmitted to the mounting block 543, causing the sanding disc 545 to smoothly contact the plate. The design of the sanding disc 545 with its inclined distribution and decreasing height enables progressive cutting, reduces the impact force on the plate in a single cut, effectively avoids edge chipping and cracking of the plate, and improves the flatness and smoothness of the grooving cut, meeting the grooving requirements of prefabricated building components. The motor provides stable power to the sanding disc 545, ensuring the cutting effect.
