Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] In one embodiment of this utility model, such as Figure 1-6As shown, this embodiment provides a fixing device for processing I-beams, the specific structure of which is as follows: Holding frame 1: Two are provided, in a relative position. The bottom side of the holding frame 1 is equipped with a slot 11, which is used to engage the flange of the I-beam, enabling initial positioning of the I-beam. On one side of each holding frame 1, a horizontally oriented first connecting rod 12 and a second connecting rod 13 are fixedly installed sequentially from top to bottom. Handle 2 and support sleeve 3: The two ends of the handle 2 are respectively axially slidingly connected to the first connecting rod 12 of the two holding frames 1, facilitating adjustment of the handle 2 position to adapt to different operating requirements. The two ends of the support sleeve 3 are also axially slidingly connected to the second connecting rod 13 of the two holding frames 1, providing auxiliary support for the operation of the handle 2. Protractor 4: The protractor 4 is fixed to the upper outer corner of the slot 11 of one of the holding frames 1. The protractor 4 is provided with a fan-shaped groove 41, which, with the hinge axis as the center, provides a trajectory reference for angle adjustment. Meanwhile, the protractor 4 is also equipped with a positioning hole, which corresponds to the movement trajectory of the fixed angle positioning blind hole 51, for precisely locking a specific angle. L-shaped angle positioning component: Its corner edge is hinged to the holding frame 1 via a hinge shaft, providing flexibility for angle adjustment. The upper surface of the L-shaped angle positioning component has at least one fixed angle positioning blind hole 51 and an arbitrary angle positioning blind hole 52, which can meet various angle fixing requirements. Angle locking mechanism: This mechanism passes through the positioning hole of the protractor 4 and the positioning blind hole of the angle positioning component, thereby locking the angle between the holding frame 1 and the L-shaped angle positioning component, ensuring the stability of the I-beam's angle during processing.

[0028] In another embodiment of this utility model, the short end of the L-shaped angle positioning member is hinged to the pressure holder 1 via a hinge shaft, and a fixed angle positioning blind hole 51 is formed on the upper surface of the long side along its length direction, and an arbitrary angle positioning blind hole 52 is formed along the arc trajectory of the corresponding fan-shaped groove 41 on the surface of the long side. This structural design makes angle adjustment more precise and convenient.

[0029] In another embodiment of this utility model, the positioning holes include right-angle positioning holes 42, 30° angle positioning holes, 45° angle positioning holes and 60° angle positioning holes. The positions of these positioning holes are precisely matched with the movement trajectory of the fixed-angle positioning blind hole 51, which can quickly achieve the fixing of common angles and improve processing efficiency.

[0030] In another embodiment of this utility model, the handle 2 has anti-slip texture in the middle, which effectively increases the friction between the operator's hand and the handle 2, preventing the handle 2 from slipping during operation. The two ends of the handle 2 are connected to the first connecting rod 12 through sliding bearings with clearance fit, ensuring the smooth sliding of the handle 2.

[0031] In another embodiment of this utility model, the support sleeve 3 adopts a telescopic sleeve structure, consisting of an inner sleeve and an outer sleeve. The outer wall of the inner sleeve is provided with elastic positioning beads, and the inner wall of the outer sleeve is provided with axially arranged positioning grooves. Through the cooperation of the elastic positioning beads and the positioning grooves, the length of the support sleeve 3 can be adjusted according to actual needs, enhancing the adaptability of the device.

[0032] In another embodiment of this invention, both the first connecting rod 12 and the second connecting rod 13 are telescopic rods with adjustable lengths, and the surface of the rods is marked with length scales. This design allows operators to accurately adjust the length of the connecting rods according to the dimensions of the I-beam, improving the device's versatility for I-beams of different sizes.

[0033] In another embodiment of this invention, the diameter of the fixed-angle positioning blind hole 51 is larger than the diameter of the arbitrary-angle positioning blind hole 52, and the diameters of the right-angle positioning hole 42, the 30° angle positioning hole, the 45° angle positioning hole, and the 60° angle positioning hole of the protractor 4 match those of the fixed-angle positioning blind hole 51. This hole diameter design facilitates the differentiation of different types of positioning holes while ensuring the stability of the angle locking mechanism at a fixed angle.

[0034] In another embodiment of this utility model, the protractor 4 is made of transparent engineering plastic, which has good light transmittance, making it convenient for operators to observe the relative position of the I-beam and the protractor 4. Fluorescent angle scale lines are provided on the surface, allowing for clear reading of angle values ​​even in low-light working environments.

[0035] The core structure of this utility model for fixing devices in I-beam processing is a pressure holder 1, which is integrally formed from a first connecting rod 12, a second connecting rod 13, and a slot 11. The device operates in a standardized and orderly manner, ensuring precise positioning and angle adjustment during I-beam processing.

[0036] In the assembly phase, first, place the two holding frames 1 in a facing position, ensuring precise alignment of the slots 11. Then, connect the two ends of the handle 2 to the first connecting rod 12 via sliding bearings with a clearance fit. This connection allows the handle 2 to slide smoothly during subsequent operations, facilitating adjustments to the position of the holding frames 1. Simultaneously, connect the two ends of the support sleeve 3 axially to the second connecting rod 13, providing auxiliary support during device operation. The protractor 4 needs to be fixed to the outer upper corner of the slot 11 of one of the holding frames 1; strict control of positional accuracy is crucial during installation. Next, hinge the L-shaped angle positioning component to the corner edge of the holding frame 1 via a hinge shaft, ensuring flexible rotation and laying the foundation for subsequent angle adjustments. Finally, prepare the angle locking mechanism, such as bolts or pins, ensuring they can smoothly pass through the positioning holes of the protractor 4 and the blind positioning holes of the angle positioning component for fixation after angle adjustment.

[0037] During use, the device needs to be adjusted according to the actual dimensions of the I-beam. By observing the clearly marked scale on the surface of the rod, the lengths of the first connecting rod 12 and the second connecting rod 13 are flexibly adjusted so that the spacing between the slots 11 of the two holding frames 1 perfectly matches the width of the I-beam flange. Then, the flange of the I-beam is precisely inserted into the slots 11 of the holding frame 1 to complete the initial positioning.

[0038] If the angle of the I-beam needs to be adjusted, it can be achieved by rotating the L-shaped angle positioning component. When the fixed angle positioning blind hole 51 on the L-shaped angle positioning component is precisely aligned with the corresponding positioning hole (such as right-angle positioning hole 42, 30° angle positioning hole, etc.) on the protractor 4, the angle locking mechanism (such as a bolt) is quickly passed through the positioning hole and the positioning blind hole and tightened to the specified torque, thus firmly fixing the I-beam at a specific angle. To adjust to any angle, the L-shaped angle positioning component is rotated to align the arbitrary angle positioning blind hole 52 with the corresponding position on the protractor 4, and then the angle locking mechanism is used to lock it. During the entire operation, the operator can easily adjust the position of the pressure frame 1 through the handle 2. At this time, the support sleeve 3 will slide synchronously, continuously providing stable auxiliary support for the device.

[0039] This fixing device plays an important role in various processing scenarios of I-beams:

[0040] 1. Welding Process: During H-beam welding, this device can be used to precisely fix the H-beam at the required angle according to specific welding process requirements. For example, when performing right-angle welding, align the fixed angle positioning blind hole 51 of the L-shaped angle positioning component with the right-angle positioning hole 42 of the protractor 4 and lock them firmly before proceeding with the welding operation. This effectively ensures the accuracy of the welding position, significantly improves the welding quality, and reduces welding defects caused by positioning deviations.

[0041] 2. Cutting Processing: When cutting I-beams, this device can stably fix the I-beams at a suitable angle, greatly facilitating the cutting operation. Taking cutting a 30° angle I-beam as an example, adjusting the L-shaped angle positioning piece to the corresponding angle and reliably locking it before cutting can effectively ensure the accuracy of the cutting angle, reduce cutting errors, and improve the precision and efficiency of the cutting process.

[0042] 3. Drilling: When drilling holes in I-beams, this device securely fixes the I-beam and adjusts it to the appropriate angle, ensuring more precise drilling positions. By preventing the I-beam from wobbling during drilling, it significantly improves drilling accuracy and efficiency, reduces scrap rates, and enhances overall processing quality.

[0043] In summary, this utility model's fixing device for I-beam processing, with its unique and ingenious structural design, successfully achieves precise angle adjustment and stable fixation of I-beams. The device is highly versatile, adaptable to the processing needs of various I-beam specifications; it is easy to operate, effectively reducing the labor intensity and skill requirements of operators. In practical applications, it can significantly improve the efficiency and quality of I-beam processing, comprehensively meeting the stringent requirements of different processing scenarios, and has extremely broad market application prospects, expected to be widely promoted and applied in the field of I-beam processing.
