Description

Technical Field

[0001] This utility model relates to the field of light steel keel technology, and in particular to a positioning and fixing device for cutting light steel keels. Background Technology

[0002] Light steel keel is a material used in building and decoration for wall and ceiling structures. It is made of cold-formed light steel material, commonly galvanized steel sheet, using high-quality continuous hot-dip galvanized strip as raw material, and rolled by cold bending process. The positioning and fixing device for cutting light steel keel is a key piece of equipment to ensure cutting accuracy and stability during the processing of light steel keel.

[0003] In use, this utility model faces challenges because the device needs to handle light steel keels of varying sizes and specifications. Traditional light steel keel cutting devices cannot effectively limit their movement when fixing them, making them unsuitable for different sizes of light steel keels. This reduces the equipment's versatility, necessitates frequent replacement or adjustment of the fixing device, increases operational complexity and downtime, and requires repeated adjustments to the fixing device when cutting multiple specifications of light steel keels, reducing production efficiency and affecting the continuity of large-scale production. Unstable fixing limits can cause keel displacement during cutting, resulting in dimensional deviations or rough edges, affecting product quality and consistency. Therefore, an improved positioning and fixing device for light steel keel cutting is needed to solve these problems. Utility Model Content

[0004] To overcome the problem that the positioning and fixing device for cutting light steel keel cannot be adjusted and fixed according to the size of the light steel keel, which reduces the versatility of the equipment, reduces production efficiency, and affects product quality and consistency.

[0005] The technical solution of this utility model is as follows: a positioning and fixing device for cutting light steel keel, including a supporting cutting platform, a first air pump and a positioning component. A conveying device for driving the light steel keel is provided on one side of the supporting cutting platform. An installation support base for supporting the positioning component is provided on one side of the supporting cutting platform. A support bracket for supporting the supporting cutting platform, the conveying device and the installation support base is fixedly connected to the bottom of the supporting cutting platform, the conveying device and the installation support base. A cutting device for cutting light steel keel is provided on the supporting cutting platform. The positioning component is provided on the installation support base. A first air pump is provided on the supporting cutting platform. A first pneumatic telescopic rod is provided on the first air pump. A second air pump is provided on the first pneumatic telescopic rod. The second air pump slides inside the supporting cutting platform. A second pneumatic telescopic rod is provided on the second air pump. A pressing and pushing plate is provided on the second pneumatic telescopic rod. A fixing and limiting block for limiting the light steel keel is provided on the supporting cutting platform.

[0006] Preferably, the support cutting platform has a groove at the corresponding position of the second air pump, and the second air pump slides inside the groove.

[0007] Preferably, there are two second pneumatic telescopic rods, and the two second pneumatic telescopic rods are symmetrically arranged on the second air pump.

[0008] Preferably, a mounting support is fixedly connected to a mounting connector, a sliding limit post is slidably connected inside the mounting connector, a fixed mounting rod is fixedly connected inside the mounting connector, a compression limit plate is fixedly connected to the sliding limit post, the compression limit plate is slidably connected inside the mounting connector, and a return spring is fixedly connected between the compression limit plate and the mounting connector.

[0009] Preferably, there are two fixed mounting rods, and the two fixed mounting rods are symmetrically fixedly connected inside the mounting connector.

[0010] Preferably, a drive motor is fixedly connected to the mounting support, and a rotating threaded rod is fixedly connected to the output end of the drive motor. The rotating threaded rod is rotatably connected inside the mounting support, and a limit fixing rod is fixedly connected inside the mounting support. A positioning sliding plate is threadedly connected to the rotating threaded rod and slidably connected to the limit fixing rod. A measuring probe for positioning distance is provided on the positioning sliding plate, and a scale plate for precise guidance of positioning length is fixedly connected to the mounting support.

[0011] Preferably, the position of the ray from the measuring probe is perpendicular to the scale plate.

[0012] Preferably, the mounting support has a groove at the corresponding position of the positioning sliding plate, and the positioning sliding plate slides inside the groove.

[0013] The beneficial effects of this utility model are: 1. Compared to the positioning and fixing device for cutting light steel keel, which cannot be adjusted according to the size of the light steel keel, the second pneumatic telescopic rod on the second air pump pushes the extrusion plate to push the light steel keel into contact with the fixed limit block. This allows for adjustment according to the size of the light steel keel and allows for limiting the light steel keel as needed. This improves the equipment's versatility, eliminates the need for frequent replacement or adjustment of the fixing device, reduces operational complexity and downtime, eliminates the need for repeated debugging of the fixing device, improves production efficiency, ensures the continuity of large-scale production, and guarantees product quality and consistency.

[0014] 2. By rotating the threaded rod and connecting it to the positioning sliding plate, the positioning sliding plate slides inside the mounting support, causing its measuring probe to point to the required mark on the scale plate to achieve positioning. By pre-setting positioning parameters, it can be ensured that the length of the keel cut each time fully meets the design requirements, with the error controlled within the millimeter range. This avoids dimensional deviations caused by manual measurement or adjustment. There is no need for repeated manual measurement and marking of the cutting position. Operators only need to input the target length to complete the positioning, reducing labor intensity and shortening the processing time per piece. Precise positioning can avoid insufficient or excessive keel length due to cutting errors, reducing the defect rate and scrap production, and directly reducing raw material consumption costs.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 - Figure 5This utility model provides an embodiment of a positioning and fixing device for cutting light steel keel, including a supporting cutting platform 1, a first air pump 801, and a positioning component. A conveying device 2 for transporting the light steel keel is provided on one side of the supporting cutting platform 1. A mounting support 3 for supporting the positioning component is provided on one side of the supporting cutting platform 1. A support bracket 4 for supporting the supporting cutting platform 1, the conveying device 2, and the mounting support 3 is fixedly connected to the bottom of the supporting cutting platform 1, the conveying device 2, and the mounting support 3. A cutting device 5 for cutting the light steel keel is provided on the supporting cutting platform 1. The positioning component is provided on the mounting support 3. The first air pump 801 is provided on the supporting cutting platform 1, and a first pneumatic telescopic rod 802 is provided on the first air pump 801. A second air pump 803 is installed on the 802, and the second air pump 803 slides inside the supporting cutting platform 1. A second pneumatic telescopic rod 804 is installed on the second air pump 803, and a pressing push plate 805 is installed on the second pneumatic telescopic rod 804. A fixed limiting block 811 for limiting the light steel keel is installed on the supporting cutting platform 1. The first air pump 801 drives the first pneumatic telescopic rod 802 to push the second air pump 803 to slide inside the supporting cutting platform 1, so that the second air pump 803 slides to a suitable position, and the light steel keel is transported to the bottom of the cutting device 5 through the supporting cutting platform 1. The second air pump 803 drives the second pneumatic telescopic rod 804 to drive the pressing push plate 805 to push the light steel keel to contact the fixed limiting block 811 to fix it.

[0019] Please see Figure 2 - Figure 3In this embodiment, the supporting cutting platform 1 has a groove at the corresponding position of the second air pump 803. The second air pump 803 slides inside the groove. The groove at the corresponding position of the second air pump 803 inside the supporting cutting platform 1 makes the second air pump 803 more stable when sliding inside the groove. Two second pneumatic telescopic rods 804 are provided, and the two second pneumatic telescopic rods 804 are symmetrically arranged on the second air pump 803. The two second pneumatic telescopic rods 804 make the compression and pushing plate 805 more stable when fixing the light steel keel. An installation connecting seat 806 is fixedly connected to the mounting support 3. A sliding limiting post 807 is slidably connected inside the installation connecting seat 806. A fixed mounting rod 808 is fixedly connected, and a compression limiting plate 809 is fixedly connected to the sliding limiting post 807. The compression limiting plate 809 is slidably connected inside the mounting connecting seat 806. A return spring 810 is fixedly connected between the compression limiting plate 809 and the mounting connecting seat 806. The return spring 810 pushes the compression limiting plate 809 to contact the light steel keel under the limitation of the fixed mounting rod 808, thereby fixing the light steel keel. There are two fixed mounting rods 808, and the two fixed mounting rods 808 are symmetrically fixedly connected inside the mounting connecting seat 806. The two fixed mounting rods 808 make the compression limiting plate 809 more stable when fixing the light steel keel.

[0020] Please see Figure 4 - Figure 5 In this embodiment, a drive motor 901 is fixedly connected to the mounting support 3. A rotating threaded rod 902 is fixedly connected to the output end of the drive motor 901. The rotating threaded rod 902 is rotatably connected inside the mounting support 3. A limit fixing rod 903 is fixedly connected inside the mounting support 3. A positioning sliding plate 904 is threadedly connected to the rotating threaded rod 902. The positioning sliding plate 904 is slidably connected to the limit fixing rod 903. A measuring probe 905 for positioning distance is provided on the positioning sliding plate 904. A scale plate 906 for precisely guiding the positioning length is fixedly connected to the mounting support 3. The drive motor 901 drives the rotating threaded rod 902 to rotate within the mounting support 3. The internal rotation of the mounting support 3, through the threaded connection between the rotating threaded rod 902 and the positioning sliding plate 904, causes the positioning sliding plate 904 to slide inside the mounting support 3 under the limitation of the limiting fixing rod 903. The position of the ray of the measuring probe 905 is perpendicular to the scale plate 906. The perpendicularity between the positioning sliding plate 904 and the scale plate 906 ensures the accuracy of the positioning measurement. The mounting support 3 has a groove at the corresponding position of the positioning sliding plate 904. The positioning sliding plate 904 slides inside the groove. The groove inside the mounting support 3 corresponding to the position of the positioning sliding plate 904 limits the sliding of the positioning sliding plate 904 inside the groove.

[0021] During operation, the drive motor 901 drives the rotating threaded rod 902 to rotate inside the mounting support 3. With the threaded connection between the rotating threaded rod 902 and the positioning sliding plate 904, the positioning sliding plate 904 slides inside the mounting support 3 under the limitation of the limiting fixing rod 903. The measuring probe 905 monitors the indication on the scale plate 906, and the positioning of the light steel keel is achieved through contact between the light steel keel and the positioning sliding plate 904. When limiting the light steel keel, the first air pump 801 drives the first pneumatic telescopic rod 802 to push the second air pump 803 to support the cutting platform 1. The internal sliding mechanism allows the second air pump 803 to slide to a suitable position, transporting the light steel keel to the underside of the cutting device 5 via the supporting cutting platform 1. The second air pump 803 drives the second pneumatic telescopic rod 804, which in turn drives the extrusion push plate 805 to push the light steel keel into contact with the fixed limit block 811, thus fixing it. The reset spring 810 pushes the extrusion limit plate 809 to contact the light steel keel under the limit of the fixed mounting rod 808, thus fixing the light steel keel and making the cutting of the light steel keel more stable. The light steel keel is then fixed before cutting.

[0022] Through the above steps, the second pneumatic telescopic rod 804 on the second air pump 803 pushes the extrusion push plate 805 to push the light steel keel into contact with the fixed limit block 811, thereby fixing and limiting the light steel keel. This solves the problem that the positioning and fixing device for cutting light steel keel cannot be adjusted and fixed according to the size of the light steel keel, which leads to reduced equipment versatility, reduced production efficiency, and affected product quality and consistency.
