Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and specifically to a cutting aid. Background Technology

[0002] In existing technologies, gas cutting guns are typically used to cut bevels and straight edges on parts, H-beams, and other materials. Gas cutting is a thermal cutting technique that uses the flame generated by the combustion of combustible gas and oxygen to separate materials. The flame preheats the material to its ignition point at the starting point, and then an oxygen stream is injected, causing the metal material to oxidize and burn violently. The resulting oxide slag is blown away by the airflow, forming a cut.

[0003] Currently, the standard operation involves workers holding a gas cutting torch to complete the cut. However, due to the hand-held operation, it is impossible to effectively avoid quality problems such as uneven cuts caused by the cutting nozzle of the gas cutting torch shaking due to hand tremors. Manual hand-held cutting is not only inefficient and produces poor bevel and straight edges, but also involves high labor intensity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cutting aid that can connect to the cutting nozzle using an angle adjustment structure, making it easy to adjust the cutting angle. Furthermore, it utilizes a linear guide rail for cutting guidance, reducing the problem of poor cut surface formation caused by hand-held cutting due to vibration. It is easy to operate and produces a neat cut surface.

[0005] This utility model is achieved through the following technical solution: A cutting aid is provided, including a support platform. A linear guide rail is connected to the support platform via a vertical strut, and a slider is slidably connected to the linear guide rail. A clamp for holding a cutting nozzle is connected to the slider via an angle adjustment structure. The clamp includes an annular fixed sleeve and an annular retainer movably disposed within the fixed sleeve. A polygonal through hole is provided in the center of the annular retainer for engaging cutting nozzles of different diameters. A threaded through hole is provided on the fixed sleeve, and a tightening screw for tightening and fixing the annular retainer is threaded into the threaded through hole.

[0006] This solution utilizes a support platform to place a steel plate, which is then secured to a matching cutting nozzle via a ring-shaped clamp. The nozzle is then positioned within a fixed sleeve using a tightening screw, thus providing positioning support for the cutting nozzle. Combined with the sliding guidance of the linear guide rail and slider, the cutting nozzle can be driven to move linearly for cutting, ensuring smooth movement and avoiding poor cut surface formation due to vibration.

[0007] Furthermore, the angle adjustment structure includes a positioning rod with an end-connected fixed sleeve and a positioning plate connected to the slider. The positioning plate has at least one positioning groove on one side along the length of the linear guide rail. The positioning groove is provided with positioning slopes of 45°, 60° and 90° respectively, and threaded holes are provided on the positioning slopes respectively. The positioning rod fits against the positioning slope in the length direction and is connected to the positioning slope by positioning screws.

[0008] One end of the positioning rod is connected to the fixing sleeve to support the fixture. The positioning groove can be set with positioning slopes of different angles, so that the positioning rod can be connected to the positioning slope with positioning screws, so that the cutting nozzle held by the fixture can maintain the required angle with the steel plate, thereby facilitating the adjustment of the cutting angle to meet the needs of different cutting surfaces.

[0009] Furthermore, the angle adjustment structure includes a fixed box connected to the slider. Inside the fixed box, a rotating shaft and a worm gear are rotatably mounted perpendicularly to each other. The rotating shaft is parallel to the linear guide rail, and a worm wheel is installed in the middle of the rotating shaft. One end of the rotating shaft is vertically connected to a telescopic rod connected to a fixed sleeve outside the fixed box. The worm gear is vertically arranged to the linear guide rail and meshes with the worm wheel for transmission. One end of the worm gear is connected to a handwheel outside the fixed box.

[0010] The fixed box contains a rotating shaft and a worm gear. A worm wheel is mounted on the rotating shaft. The worm gear is driven to rotate by a handwheel, which in turn drives the worm wheel to drive the rotating shaft and adjust the angle of the clamp at the end of the telescopic rod. This allows the cutting nozzle to be infinitely varied in different angle ranges. At the same time, the worm gear and worm wheel structure has a self-locking structure, which can lock itself after the angle is adjusted, allowing for a wider range of cutting nozzle angle adjustments.

[0011] Furthermore, a pressure rod is vertically connected to the bottom of the middle section of the linear guide, and an eccentric pressure wheel with a lever is hinged to the end of the pressure rod, forming a clamping space between the eccentric pressure wheel and the support platform.

[0012] The bottom of the linear guide is connected to a pressure rod, and the end of the pressure rod is hinged to an eccentric pressure roller. The steel plate can be clamped on the support platform by rotating the eccentric pressure roller, thereby ensuring the stability of the steel plate during cutting.

[0013] Preferably, limit blocks are provided at both ends of the linear guide.

[0014] Limit blocks are set at both ends of the linear guide rail. The limit blocks can be used to limit the slider and prevent the slider from falling off the linear guide rail.

[0015] The beneficial effects of this utility model are: This invention utilizes a clamp to position and clamp the cutting nozzle, and an angle adjustment structure supports and adjusts the cutting angle of the nozzle. The use of a linear guide rail and a slider greatly improves the stability of cutting, making it easy to operate, highly efficient, and producing a good cut surface. It effectively avoids quality problems such as uneven cutting caused by hand tremors.

[0016] In addition, compared with the existing manual hand-held cutting operation, it not only reduces labor intensity, improves work efficiency and cutting quality, but also improves the safety of use. Attached Figure Description

[0025] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] Example 1: A cutting aid includes a support platform 1, on which a linear guide rail 3 is connected via a vertical strut 2, and a slider 5 is slidably connected to the linear guide rail 3. Limiting blocks 4 are respectively provided at both ends of the linear guide rail 3 to prevent the slider 5 from dislodging. A clamp 8 for holding a cutting nozzle is connected to the slider 5 via an angle adjustment structure.

[0027] The clamp 8 includes an annular fixed sleeve 81 and an annular retainer 82 movably disposed within the fixed sleeve 81. The annular retainer 82 has a polygonal through hole 83 in the center for engaging with cutting nozzles of different diameters. The fixed sleeve 81 is provided with a threaded through hole, and a tightening screw 84 for tightening and fixing the annular retainer 82 is threadedly connected in the threaded through hole.

[0028] The angle adjustment structure includes a positioning rod 9 with an end-connected fixing sleeve 81 and a positioning plate 6 connected to the slider 5. The positioning plate 6 has at least one positioning groove 7 along one side of the linear guide rail's length direction. Figure 4 As shown, from right to left, the positioning groove 7 is provided with positioning inclined surfaces 11 of 45°, 60° and 90° respectively, and threaded holes 21 are opened on the positioning inclined surfaces 11 respectively. The positioning rod 9 fits against the positioning inclined surface 11 in the length direction and is connected to the positioning inclined surface 11 by positioning screws 10.

[0029] The working process of this embodiment: First, select a cutting nozzle of appropriate diameter according to the thickness of the steel plate, and attach a ring-shaped retainer 82 to the cutting nozzle. Place the ring-shaped retainer 82 into the fixing sleeve 81, and use the tightening screw 84 to tighten and fix the ring-shaped retainer 82, so that the cutting nozzle can be stably supported and fixed on the positioning rod 9. According to the cutting angle requirements of the steel plate, select the positioning rod 9 to install on the positioning inclined surface 11 at the corresponding angle. Taking 90° as an example, place the positioning rod 9 against the 90° positioning inclined surface 11, and tighten it with the positioning screw 10 to fix the positioning rod 9 to the positioning plate 6. Turn on the cutting gun, the cutting nozzle sprays cutting flame, pushes the slider 5 to drive the positioning rod 9 and the cutting nozzle to move laterally along the linear guide rail 3 to cut, which can achieve stable cutting. Compared with manual hand operation, it greatly improves the flatness of the cut surface, has high cutting efficiency, and reduces labor intensity.

[0030] Example 2: The difference between this embodiment and Embodiment 1 is that: the angle adjustment structure includes a fixed box 12 connected to the slider 5, and a rotating shaft 14 and a worm gear 13 that are perpendicular to each other are rotatably installed inside the fixed box 12. The rotating shaft 14 is arranged parallel to the linear guide rail 3, and a worm wheel 15 is installed in the middle of the rotating shaft 14. One end of the rotating shaft 14 is vertically connected to a telescopic rod 17 connected to the fixed sleeve 81 outside the fixed box 12; the worm gear 13 is arranged perpendicularly to the linear guide rail 3 and meshes with the worm wheel 15 for transmission, and one end of the worm gear 13 is connected to a handwheel 16 outside the fixed box 12.

[0031] A pressure rod 18 is vertically connected to the bottom of the middle section of the linear guide rail 3. An eccentric pressure wheel 19 with a lever is hinged to the end of the pressure rod 18. A clamping space is formed between the eccentric pressure wheel 19 and the support platform 1.

[0032] In this embodiment, the clamping and positioning steps for the cutting nozzle are the same as in Embodiment 1. Before cutting, the steel plate is clamped and fixed on the support platform 1 by rotating the eccentric pressure roller 19 through the lever 20. Then, the handwheel 16 is rotated, and the worm gear 13 drives the worm wheel 15 to rotate the rotating shaft 14. The rotating shaft 14 then drives the telescopic rod 17 to adjust its angle, which in turn drives the cutting nozzle clamped by the clamp 8 at the end of the telescopic rod 17 to adjust its angle. The angle of the cutting nozzle can be adjusted arbitrarily according to the needs of use. With the extension and retraction of the telescopic rod 17, the distance between the cutting nozzle and the steel plate can be adjusted to maintain the optimal distance during cutting. After the angle is adjusted, the self-locking performance of the worm gear 13 and the worm wheel 15 ensures that the cutting angle of the cutting nozzle will not change, thus ensuring the consistency of the cutting angle. With the guiding effect of the slider 5 and the linear guide rail 3, the stability of cutting can be guaranteed.
