Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding positioning devices, and in particular to a welding positioning device for processing fireproof windows. Background Technology
[0002] Fire-resistant windows are building components consisting of steel frames, steel sashes, and fire-resistant glass. They are primarily used to isolate and prevent the spread of fire, and are commonly installed in openings in exterior walls where fire separation distances are insufficient, in skylights or firewalls, in areas of fire-resistant partitions requiring observation, and in openings in exterior walls where vertical fire spread needs to be prevented. In the production and processing of fire-resistant windows, the welding of the window frame is a critical step, directly affecting the structural strength and fire resistance of the product. Existing welding positioning devices typically use fixed brackets or clamping mechanisms to position and clamp the window frame to ensure its stability during welding. However, these devices are often relatively simple in design, focusing primarily on the overall fixation of the window frame and lacking precise alignment control at the corner joints, resulting in inconsistent welding quality and making it difficult to meet the high standards required for fire-resistant window production.
[0003] Most existing clamping devices employ a two-sided clamping mechanism, applying pressure to both sides of the window frame for fixation. However, the frame materials of fireproof windows (such as steel or aluminum alloy) typically have poor resistance to pressure on both sides, making them prone to deformation or damage during clamping. Furthermore, existing clamping devices often use electric clamping, where the clamping force depends on the motor output, making precise adjustment difficult. Excessive clamping force can easily damage the window frame structure, even causing cracks or deformation, severely impacting the overall quality and service life of the fireproof window.

[0024] Example
[0025] Reference Figures 1-4 This utility model provides a welding positioning device for fireproof window processing, which aims to achieve precise positioning and stable clamping of fireproof window frames, so as to improve welding quality and production efficiency.
[0026] Specifically, the device includes a base 1, which serves as the supporting foundation for the entire device. Made of high-strength metal, the base 1 ensures the stability and durability of the overall structure, making it suitable for long-term use in high-temperature welding environments. A positioning groove 2 is formed on the upper surface of the base 1. This rectangular groove has a depth and size adapted to the placement of the fireproof window frame, providing initial positioning space and ensuring the window frame does not shift during processing. Right-angle positioning blocks 3 are evenly distributed at the four corners inside the positioning groove 2. These blocks feature a right-angle design, with their inner angles precisely matching the corner shape of the window frame, allowing them to fit tightly against the four corners and ensuring accurate alignment during welding. Moving plates 4 are connected to the opposite sides of the two right-angle positioning blocks 3 on the left and two on the right. These moving plates 4 serve as support and transmission carriers for the right-angle positioning blocks 3, moving horizontally to move them closer to or away from the window frame, thus achieving clamping or releasing actions. The bottom ends of both movable plates 4 are connected to the first adjustment assembly 6 via the first connecting block 5. The first connecting block 5 is a robust connector that ensures stable transmission between the movable plate 4 and the first adjustment assembly 6, preventing loosening or deviation during adjustment. Each of the two movable plates 4 has a second adjustment assembly 7 inside. The second adjustment assembly 7 is used to drive the right-angle positioning block 3 for fine adjustment on the movable plate 4, further improving the flexibility and precision of clamping.
[0027] Furthermore, the base 1 has symmetrically formed first moving grooves 8 on its left and right sides. These first moving grooves 8 are elongated groove structures that provide sliding space for the first adjusting component 6 and, through their symmetrical design, ensure the balance of movement of the two moving plates 4, preventing tilting during clamping. The two moving plates 4 also have symmetrically formed second moving grooves 9 at their front and rear ends. These second moving grooves 9 provide guide channels for the movement of the right-angle positioning block 3, ensuring a stable movement trajectory within the moving plate 4 and preventing uneven clamping due to offset. A cavity 10 is formed inside the moving plate 4, located between the two second moving grooves 9. This cavity 10 provides ample space for the installation and operation of the second adjusting component 7, while also reducing the weight of the moving plate 4 and improving the overall operating efficiency of the device.
[0028] Furthermore, the first adjustment component 6 includes a first threaded rod 61 rotatably connected within two first moving slots 8. The first threaded rod 61 employs a high-precision thread design to ensure smooth and accurate transmission, converting rotational motion into linear motion to drive the horizontal movement of the moving plate 4. A transmission shaft 62 is fixedly connected between the two first threaded rods 61, serving as a synchronous connection component for the two first threaded rods 61, ensuring synchronous rotation of the first threaded rods 61 on both sides, thereby enabling coordinated clamping actions of the moving plates 4 on both sides. A first drive rod 63 is fixedly connected to the left side of the left-end first threaded rod 61. The first drive rod 63 serves as a transmission medium for manual operation, penetrating the inner wall of the base 1 and extending to its exterior where a first knob 64 is fixedly connected. The first knob 64 is designed in an ergonomic shape, facilitating manual rotation by the operator to precisely control the amplitude of the clamping action. The outer surfaces of the two first threaded rods 61 are threaded with first moving blocks 65. The first moving blocks 65 are tightly threaded with the first threaded rods 61, and can move smoothly when the threaded rods rotate. Their top ends are fixedly connected to the bottoms of the two first connecting blocks 5 respectively, ensuring that the movement of the moving plate 4 is synchronized with the drive of the first threaded rods 61, and enhancing the stability of clamping.
[0029] Furthermore, the second adjustment component 7 includes driven conical teeth 71 symmetrically arranged on the front and rear sides of the cavity 10. The driven conical teeth 71 are made of high-strength alloy material with precisely machined tooth surfaces, enabling efficient power transmission and ensuring stable rotation of the second threaded rod 72. The two driven conical teeth 71 are fixedly connected to the opposite sides of each other with a second threaded rod 72, which extends into the two second moving slots 9. Through its threaded structure, it drives the movement of the right-angle positioning block 3, achieving precise clamping and adjustment of the window frame. The upper sides of the two driven conical teeth 71 are meshed with an active conical tooth 73. The active conical tooth 73 serves as a power input component, converting the rotation direction to a vertical direction through the meshing of the conical teeth, driving the two driven conical teeth 71 to rotate in opposite directions, ensuring synchronous movement of the right-angle positioning block 3. A second drive rod 74 is fixedly connected to the top of the active conical tooth 73. The second drive rod 74 penetrates the inner top wall of the movable plate 4 and extends to its outer side where a second knob 75 is fixedly connected. The second knob 75 allows the operator to manually adjust the position of the right-angle positioning block 3 to achieve precise clamping of the window frame. A second moving block 76 is threadedly connected to the outer surface of each of the two second threaded rods 72. The second moving block 76 is fixedly connected to the two right-angle positioning blocks 3 respectively via a second connecting block 11. The second connecting block 11 ensures a firm connection between the right-angle positioning block 3 and the second moving block 76, making the clamping action more stable and reliable.
[0030] It should be noted that the outer surface threads of the two first threaded rods 61 are set in opposite directions, while the outer surface threads of the two second threaded rods 72 are set in the same direction. This design ensures that when the first drive rod 63 drives the two first threaded rods 61 to rotate in the same direction, the two first moving blocks 65 can move horizontally relative to or away from each other due to the opposite thread directions. This allows the two moving plates 4 to clamp towards or away from the window frame, meeting the needs of clamping and releasing operations. When moving away from each other, the two moving plates 4 can move away from the fireproof window frame, releasing the limiting fixation and facilitating the installation and removal of the window frame. The second threaded rods 72 have the same thread direction because when the active conical tooth 73 rotates, it drives the two driven conical teeth 71 to rotate in the opposite direction. This ensures that the two second moving blocks 76 can move horizontally away from each other or relative to each other, thereby driving the two right-angle positioning blocks 3 to move closer to or away from the fireproof window for clamping, ensuring the coordination and accuracy of the clamping action. This design effectively improves the adaptability of the device to window frames of different sizes while ensuring the stability of the clamping process.
[0031] Preferably, limiting grooves 12 are provided on the left and right sides of the top of the two first moving grooves 8. The limiting grooves 12 adopt a rectangular groove structure with precise dimensions to provide stable sliding space for the limiting block 13, effectively limiting the movement range of the moving plate 4 and preventing it from losing control or deviating in positioning due to excessive movement during clamping. The limiting blocks 13 are slidably connected inside the two limiting grooves 12. The precise cooperation between the limiting blocks 13 and the limiting grooves 12 can strictly constrain the movement trajectory of the moving plate 4, ensuring the smoothness and high precision of the clamping action, while improving the safety of the device in high-intensity welding environments. Both limiting blocks 13 have baffles 14 fixedly connected to their opposite surfaces. As a key connecting and protective component, the baffles 14 penetrate the two limiting grooves 12 and extend into the first moving groove 8, where they are firmly fixed to the side wall of the first connecting block 5. This not only significantly enhances the connection stability between the moving plate 4 and the first adjusting component 6, preventing loosening or deviation during transmission, but also effectively shields the upper surface of the first moving groove 8 through its wide design. This effectively prevents metal shavings, sparks, or other debris generated during welding from falling into the first moving groove 8, thus avoiding damage or obstruction to internal workpieces (such as the first threaded rod 61 or the first moving block 65) due to debris accumulation. This extends the service life of the device and ensures continuous and stable clamping performance.
[0032] Preferably, buffer pads 15 are fixedly installed at the included angles of the four right-angle positioning blocks 3. The buffer pads 15 are made of flexible material, which can effectively absorb the impact force generated during clamping and protect the window frame surface from scratches or deformation. The interior of each of the four buffer pads 15 is filled with sponge. The sponge filling has good elasticity and cushioning performance, which can provide uniform contact pressure when the right-angle positioning blocks 3 clamp the window frame, avoid local stress concentration, effectively protect the structural integrity of the fireproof window frame, and is particularly suitable for window frame materials with weak compressive strength, thereby improving the applicability of the device and the welding quality.
[0033] The working principle of this device is as follows: First, the operator places the fireproof window frame into the positioning groove 2. The rectangular structure of the positioning groove 2 provides initial positioning for the window frame, ensuring its stable placement without displacement. Then, the operator rotates the first knob 64. The first knob 64 drives the left-end first threaded rod 61 to rotate via the first drive rod 63, and synchronously drives the other side's first threaded rod 61 to rotate in the same direction via the transmission shaft 62. Since the outer surface threads of the two first threaded rods 61 rotate in opposite directions, the two first moving blocks 65 achieve relative horizontal movement under the rotation of the threaded rods. This, in turn, drives the two moving plates 4 to move closer to the center of the positioning groove 2 via the first connecting block 5, causing the right-angle positioning blocks 3 on the left and right sides to gradually approach the sides of the window frame, forming a preliminary lateral limiting clamp, ensuring the stability of the window frame in the horizontal direction. After clamping is completed, the operator rotates the second knob 75. The second knob 75 drives the active conical tooth 73 to rotate via the second drive rod 74. The active conical tooth 73 meshes with the two driven conical teeth 71, driving the two second threaded rods 72 to rotate in opposite directions. Because the threads of the second threaded rods 72 have the same direction of rotation, the two second moving blocks 76 move horizontally relative to or away from each other under the drive of the second threaded rods 72. This, in turn, drives the right-angle positioning blocks 3 on both sides of the front and rear sides towards or away from the window frame via the second connecting block 11, thus achieving precise longitudinal clamping. During clamping, the buffer pads 15 on the right-angle positioning blocks 3 absorb the clamping force through sponge padding, protecting the window frame surface from damage and ensuring even distribution of the clamping force. Finally, through coordinated horizontal and vertical clamping, the four right-angle positioning blocks 3 precisely fit against the four right angles of the window frame, achieving firm fixation and precise positioning of the window frame. This provides a stable foundation for subsequent welding processes, ensuring the alignment accuracy and overall quality of the welded joints.
