Description

Technical Field

[0001] This utility model relates to the field of fire door processing technology, specifically a positioning and clamping device for processing steel fire doors. Background Technology

[0002] Steel fire doors are doors with a frame, leaf skeleton, and panel made of steel. The door leaf is typically filled with non-toxic and harmless fire-resistant and heat-insulating materials and fitted with fire-resistant hardware, resulting in a door with specified fire resistance performance. During production, to ensure accurate and stable positioning, steel fire doors are often placed on a work surface for positioning and clamping.

[0003] A search revealed a Chinese patent, publication number CN220463691U, which describes: "A positioning and pressing device for fire doors, comprising a worktable and a positioning plate. The worktable is mounted on the top of a frame for support. A conveyor belt is provided on the top of the worktable for conveying the fire door. The positioning plate is mounted on the top of a top plate. A drive mechanism is provided on one side of the worktable. A drive motor inside the limiting mechanism drives the positioning plate outside the lead screw to move along the inside of the limiting groove, thereby limiting and positioning the fire door. A sliding carriage is positioned on top of the fire door, so that the hydraulic rod drives the pressure plate downward. After the pressure plate at the bottom of the pressure plate abuts against the fire door, it continues to press down on the spring outside the second telescopic rod, thereby pressing and fixing the fire door, reducing the difficulty of fire door installation, preventing displacement during fire door installation, and improving installation efficiency."

[0004] Through a review of the aforementioned technologies, we found that these solutions have certain drawbacks in practice. When positioning and clamping fire doors, they primarily rely on structures such as positioning plates and pressure plates. Since the pressure plate is used to clamp the top surface of the fire door, it obstructs the top surface of the fire door, hindering the worker's processing. Although different positions on the top surface of the fire door can be processed by moving the slide, this operation is relatively cumbersome and not conducive to convenient and rapid positioning and clamping of the fire door. Therefore, to address the problems mentioned above in existing technologies, we have specifically designed a positioning and clamping device for processing steel fire doors. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and pressing device for processing steel fire doors, comprising a processing table, on which a positioning plate, a rotating roller, a limiting plate, and a pressing plate are provided; the positioning plate is fixed to one side of the top of the processing table; a limiting groove is formed at the center of the top of the processing table, and the limiting plate is slidably connected in the limiting groove and driven by a servo motor installed on one side of the processing table; the pressing plate is fixed to one side of the top of the limiting plate; and rolling grooves are formed at the top of the processing table and on both sides of the limiting groove to facilitate the insertion and rolling of the rotating roller.

[0007] As a further embodiment of this utility model: the positioning plate is designed in a "V" shape, a layer of rubber block one is glued and fixed on the side wall of the positioning plate, and a second rubber block is glued and fixed on the side wall of the pressing plate.

[0008] As a further embodiment of this utility model: a movable groove is provided at the center of the bottom wall of the limiting groove, a movable block is fixed on one side of the bottom of the limiting plate, the movable block is slidably connected in the movable groove, and the top surface of the limiting plate is flush with the top surface of the processing table.

[0009] As a further embodiment of this utility model: the power output shaft of the servo motor is movably inserted into the movable groove and is connected to a lead screw. The end of the lead screw away from the servo motor is rotatably connected to the other side of the inner wall of the movable groove, and the lead screw is threaded through the movable block in the movable groove.

[0010] As a further embodiment of this utility model: multiple rotating rollers are rotatably connected to the two rolling grooves on the top of the processing table, and the top of the rotating rollers protrudes from the top surface of the processing table.

[0011] As a further embodiment of this utility model: adjustment components are also provided on both sides of the top of the processing table. The adjustment components include a fixing block fixed on the processing table and a limiting block provided on one side of the fixing block. The bottom of the limiting block is away from the top of the processing table, and the top of the limiting block is flush with the top of the fixing block.

[0012] As a further embodiment of this utility model: an adjusting screw is threadedly connected to the middle of one side of the fixing block. One end of the adjusting screw is fixed with a handle, and the other end is threaded through the fixing block and rotatably connected to the middle of the side of the limiting block. Two limiting rods are also fixed on the side of the limiting block near the adjusting screw, and the end of the limiting rod away from the limiting block moves through the fixing block.

[0013] As a further embodiment of this utility model, it also includes a fire door body, which is positioned and pressed against the top of the processing table by a positioning plate, a pressing plate and a limiting block, and the positioning plate, the pressing plate and the limiting block are at the same height.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In this application, through the designed processing table, positioning plate, servo motor, limiting plate and pressing plate and other structures, the fire door body to be processed can be conveniently placed directly on the processing table, and the pressing plate pushes it to press and position it on the top of the processing table, realizing convenient and fast positioning and pressing of the fire door. After the fire door body is pressed and positioned, its top is not covered by any structure and is exposed, which allows the staff to perform one-time processing at multiple positions on the top surface of the fire door body. The processing does not require the movement of related parts, making the operation more convenient.

[0016] Second, in this application, the design of the rolling groove and rotating roller makes it easier for the fire door body to move before pressing and positioning. The fire door body is pressed and positioned in the form of rolling conveying, which can reduce the possibility of scratches on the bottom of the fire door body due to friction caused by sliding during the movement, thereby ensuring the quality of the fire door body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 A positioning and pressing device for processing steel fire doors includes a processing table 1, on which a positioning plate 2, a rotating roller 4, a limiting plate 8, and a pressing plate 9 are provided; the positioning plate 2 is fixed to one side of the top of the processing table 1; a limiting groove 5 is provided at the center of the top of the processing table 1, and the limiting plate 8 is slidably connected in the limiting groove 5 and driven by a servo motor 7 installed on one side of the processing table 1; the pressing plate 9 is fixed to one side of the top of the limiting plate 8; and rolling grooves 3 are provided on the top of the processing table 1 and on both sides of the limiting groove 5 to facilitate the insertion and rolling of the rotating roller 4.

[0026] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the positioning plate 2 is designed in a "V" shape, and a layer of rubber block 201 is glued and fixed on the side wall of the positioning plate 2, and a second rubber block 901 is glued and fixed on the side wall of the pressing plate 9.

[0027] Specifically, the shape design of the positioning plate 2 can achieve the effect of inserting fire door bodies 11 of different sizes, that is, to achieve positioning of fire door bodies 11 of different sizes, thereby improving applicability. The positioning plate 2 and the pressing plate 9 are respectively provided with rubber block 201 and rubber block 901 on one side, which can protect the pressing side of the fire door body 11 and prevent damage to the side of the fire door body 11 when pressing.

[0028] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, a movable groove 6 is provided at the center of the bottom wall of the limiting groove 5. A movable block 801 is fixed on one side of the bottom of the limiting plate 8. The movable block 801 is slidably connected in the movable groove 6. The top surface of the limiting plate 8 is flush with the top surface of the processing table 1. The power output shaft of the servo motor 7 is movably inserted into the movable groove 6 and is connected to a lead screw 701. The end of the lead screw 701 away from the servo motor 7 is rotatably connected to the other side of the inner wall of the movable groove 6, and the lead screw 701 is threaded through the movable block 801 in the movable groove 6.

[0029] Specifically, after the servo motor 7 is started, it can drive the lead screw 701 to rotate. When the lead screw 701 rotates, it can drive the movable block 801 to slide in the movable groove 6, thereby driving the limiting plate 8 to slide in the limiting groove 5. By driving the lead screw 701 to rotate forward and backward by the servo motor 7, the limiting plate 8 can be driven to move closer to the positioning plate 2 or away from the positioning plate 2. When it moves closer, it can realize the positioning and pressing of the fire door body 11, which is convenient for subsequent processing. When it moves away, it can release the positioning and pressing of the fire door body 11, which is convenient for the removal of the fire door body 11.

[0030] Please see Figure 1 and Figure 3 In this embodiment, multiple rotating rollers 4 are rotatably connected to the two rolling grooves 3 at the top of the processing table 1, and the top of the rotating rollers 4 protrudes from the top surface of the processing table 1.

[0031] Specifically, the rotating roller 4 can provide support and conveying effect for the movement of the fire door body 11, allowing the fire door body 11 to move smoothly on the processing table 1, and preventing the bottom of the fire door body 11 from contacting the top surface of the processing table 1 and causing scratches.

[0032] Please see Figure 1 , Figure 3 and Figure 5 In this embodiment, adjustment components 10 are also provided on both sides of the top of the processing table 1. The adjustment components 10 include a fixing block 1001 fixed on the processing table 1 and a limiting block 1002 provided on one side of the fixing block 1001. The bottom of the limiting block 1002 is away from the top of the processing table 1, and the top of the limiting block 1002 is flush with the top of the fixing block 1001. An adjustment screw 1003 is also threadedly connected to the middle of one side of the fixing block 1001. One end of the adjustment screw 1003 is fixed with a handle, and the other end is threaded through the fixing block 1001 and rotatably connected to the middle of the side of the limiting block 1002. Two limiting rods 1004 are also fixed on the side of the limiting block 1002 near the adjustment screw 1003. The end of the limiting rod 1004 away from the limiting block 1002 moves through the fixing block 1001.

[0033] Specifically, by turning the handle on the adjusting screw 1003, the limiting block 1002 can be moved, thereby adjusting the distance between the two limiting blocks 1002. This achieves the effect of limiting the two sides of the fire door body 11 of different sizes, ensuring that the fire door body 11 is stably placed between the positioning plate 2 and the pressing plate 9, achieving a good positioning and pressing purpose. The limiting rod 1004 is also provided on the limiting block 1002, which can improve the stability of the limiting block 1002 during movement. The limiting block 1002 only fits against the side of the fire door body 11 to achieve limiting, without clamping, which can ensure the normal movement of the fire door body 11. At the same time, the bottom of the limiting block 1002 is far away from the top of the processing table 1, which can facilitate the movement of the limiting block 1002 and avoid the influence of the rotating roller 4.

[0034] Please see Figure 1 and Figure 4 In this embodiment, a fire door body 11 is also included. The fire door body 11 is positioned and pressed on the top of the processing table 1 by the positioning plate 2, the pressing plate 9 and the limiting block 1002, and the positioning plate 2, the pressing plate 9 and the limiting block 1002 are at the same height.

[0035] Specifically, the positioning plate 2, the pressing plate 9, and the limiting block 1002 are all the same height, which allows the positioning plate 2, the pressing plate 9, and the limiting block 1002 to be located on the four sides of the fire door body 11 respectively, forming a positioning and pressing structure only on the sides, while the top surface of the fire door body 11 has no structure, which avoids obstruction and facilitates normal processing of the fire door body 11 by the staff.

[0036] When using:

[0037] When positioning and pressing multiple fire door bodies 11 of the same size for processing, the worker can first place the fire door body 11 on the processing table 1, use multiple rotating rollers 4 to support the fire door body 11, and then turn the two adjusting screws 1003 to push the two limiting blocks 1002 to move towards each other. Without tightening, the two limiting blocks 1002 are made to fit against the two sides of the fire door body 11, thereby limiting the two sides of the fire door body 11. That is, the distance between the two limiting blocks 1002 is the appropriate positioning position for processing multiple fire door bodies 11 of the same size, which facilitates the direct entry of the subsequent fire door bodies 11 and can directly limit the two sides of the subsequent multiple fire door bodies 11 of the same size.

[0038] Then, the servo motor 7 is started. The power output shaft of the servo motor 7 drives the lead screw 701 to rotate, thereby driving the movable block 801 to slide in the movable groove 6, which in turn drives the limiting plate 8 to slide in the limiting groove 5. When the limiting plate 8 slides, the fire door body 11 can be pushed by the pressing plate 9, causing the fire door body 11 to roll on multiple rotating rollers 4 and gradually approach the positioning plate 2, until the pressing plate 9 pushes the fire door body 11 to be pressed between the pressing plate 9 and the positioning plate 2 (e.g., Figure 3 (as shown);

[0039] After the worker finishes processing the fire door body 11 that is currently positioned and pressed, the servo motor 7 can drive the lead screw 701 to reverse, thereby causing the pressing plate 9 to stop pressing the fire door body 11 and move away from the side of the fire door body 11. At this time, the fire door body 11 can be released. Then the worker can directly remove the processed fire door body 11. Then, a new fire door body 11 of the same size that needs to be processed can be placed on multiple rotating rollers 4, and the servo motor 7 can be started again to press the fire door body 11.

[0040] It should be noted that when positioning and pressing multiple fire door bodies 11 of the same size, this solution only requires one adjustment of the adjusting component 10 to make the two limiting blocks 1002 fit against the sides of the fire door body 11. Subsequently, fire door bodies 11 of the same size can be directly limited on both sides by the two limiting blocks 1002. When positioning and pressing fire door bodies 11 of the same size for easy processing, it is only necessary to start the servo motor 7 to drive the pressing plate 9 to automatically position and press the fire door body 11, and it can ensure that there are no obstructions on the top of the fire door body 11, making the operation more convenient.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
