[0002] With the continuous development of industrial automation and intelligent technologies, semi-automatic cutting machines have gradually become the mainstream equipment for cutting operations. Semi-automatic cutting machines, through preset programs and paths, can automatically cut materials, greatly improving cutting efficiency and precision. However, semi-automatic cutting machines still face some challenges when cutting curved bevels. Due to the complex and varied shapes of curved bevels, traditional semi-automatic cutting machines often cannot adapt directly and require additional auxiliary devices to guide the cutting head to cut along a predetermined curved trajectory.

[0003] The reference patent, entitled "A Device for Assisting a Semi-Automatic Cutting Machine in Cutting Arc-Shaped Bevels" (Publication No. CN214921255U, Application Date 2021-05-18), includes a control rod and a guide wheel.

In use, the outer wall of the guide wheel contacts the arc-shaped working surface of the workpiece to be cut. This device for assisting a semi-automatic cutting machine in cutting arc-shaped bevels is lightweight, portable, and highly practical. When used in conjunction with a semi-automatic cutting machine, it can achieve arc-shaped bevel cutting, effectively ensuring the production efficiency of pressure steel pipes and thus reducing production costs.

[0004] Based on the aforementioned patent, existing auxiliary devices for semi-automatic cutting machines lack the ability to adjust the angle of the cutting end, while more precise data-driven mechanical equipment requires higher costs and is difficult to use for small-scale production. Therefore, this utility model provides a device for assisting semi-automatic cutting machines in cutting curved bevels. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides a device for assisting a semi-automatic cutting machine in cutting curved bevels. Compared with the prior art, it has the following advantages:

[0016] (1) The device for assisting a semi-automatic cutting machine in cutting arc-shaped bevels is designed with an adjustment component. The adjustment component is located inside the support component and is used to adjust the angle of the movable support rod relative to the vertical rod, thereby achieving precise adjustment of the cutting head angle. When the worm gear is rotated, the adjustment rod is driven to move along the positioning groove through the transmission of the worm wheel and worm gear, thereby changing the included angle between the movable support rod and the vertical rod, and achieving adjustment of the cutting head angle. It can adjust the angle of the cutting end of the semi-automatic cutting machine. At the same time, it is cheaper than precision data equipment and can be used for small-scale production.

[0017] (2) The device for assisting a semi-automatic cutting machine in cutting arc bevels is designed with a clamping component for fixing the cutting head to ensure its stability during the cutting process. When the screw is rotated, the push rod will move back and forth along the screw, pushing or pulling the trapezoidal block to move synchronously. The trapezoidal block moves forward and then pushes the sliding plate to slide in a direction. The first clamping block and the second clamping block collide and clamp the cutting head of the semi-automatic cutting machine. The elastic telescopic rod is squeezed and clamps the cutting head. It can be adapted to the cutting heads of semi-automatic cutting machines of different sizes. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a device for assisting a semi-automatic cutting machine in cutting arc-shaped bevels, including a base frame 1. The upper end of the base frame 1 is provided with an adjustment mechanism for adjusting the angle of the cutting head of the semi-automatic cutting machine. The adjustment mechanism includes: a support component 2, which is located on the upper end of the base frame 1 and includes a vertical rod 21 rotatably mounted on the upper end of the base frame 1, and a movable support rod 22 is movably mounted on the top end of the vertical rod 21; and an adjustment component 3, which is located inside the support component 2 and includes a drive part 31 mounted on the movable support rod 22. An adjustment rod 32 is fixed at the lower end of the drive part 31. A positioning plate 33 is fixed on the side of the vertical rod 21 near the movable support rod 22, and a positioning groove 34 is provided on the positioning plate 33 for the directional movement of the adjustment rod 32.

[0025] In this embodiment, the drive unit 31 includes a rotating worm gear 311 rotatably mounted on the upper end of the movable support rod 22. The movable support rod 22 is provided with a through groove, and a worm wheel 312 that meshes with the rotating worm gear 311 is rotatably connected to the inside of the through groove. The lower end of the worm wheel 312 is fixed to the adjusting rod 32. When the rotating worm gear 311 rotates, the adjusting rod 32 is driven to move along the positioning groove 34 through the transmission of the worm wheel and worm gear, thereby changing the angle between the movable support rod 22 and the vertical rod 21, and realizing the adjustment of the cutting head angle.

[0026] In this embodiment, a clamping assembly 4 is provided at the front end of the movable support rod 22. The clamping assembly 4 includes a screw 41 rotatably mounted on the upper end of the adjusting rod 32, and the screw 41 is connected to a rotating worm gear 311. A push rod 42 that abuts against the upper surface of the movable support rod 22 is threaded onto the screw 41. A trapezoidal block 43 is fixed to one side of the push rod 42. A base rod 44 is fixed to the front end of the adjusting rod 32, and a sliding plate 45 is slidably mounted on one side of the base rod 44. An elastic telescopic rod 46 is fixed to one side of the sliding plate 45, and a first clamping block 47 is fixed to the other end of the elastic telescopic rod 46. The base rod 44 has a second clamping block 48 fixed on the side opposite to the first clamping block 47. When the screw 41 is rotated, the extension rod 42 will move back and forth along the screw 41, pushing or pulling the trapezoidal block 43 to move synchronously. The forward movement of the trapezoidal block 43 will then push the sliding plate 45 to slide in a direction. The first clamping block 47 and the second clamping block 48 will clamp the cutting head of the semi-automatic cutting machine. The elastic telescopic rod 46 will be compressed. The elastic telescopic rod 46 is specifically composed of a rod sleeve and an internal telescopic rod body. A spring is connected between the rod head and the rod sleeve for easy and quick reset.

[0027] In this embodiment, a housing 5 and a cylinder 8 are fixed inside the base frame 1. A central shaft is rotatably mounted inside the housing 5, and a gear 7 is welded on the central shaft. A piston rod extending into the housing 5 is connected to the end of the cylinder 8. A rack 6 that meshes with the gear 7 is fixed to the end of the piston rod. The top of the central shaft passes through the top wall of the base frame 1 and is fixed to the vertical rod 21. By starting the cylinder 8, the piston rod drives the rack 6 to move back and forth. Through the meshing transmission between the gear 7 and the rack 6, the central shaft and the vertical rod 21 are driven to rotate. Since the vertical rod 21 is connected to the movable support rod 22, it can drive the entire support assembly 2 and the cutting head to move in an arc.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the support assembly 2 is located on the upper end of the base frame 1, including a vertical rod 21 rotatably mounted on the base frame 1 and a movable support rod 22 movably mounted on the top of the vertical rod 21. The vertical rod 21 can rotate around its connection point with the base frame 1, while the movable support rod 22 can move within a certain range on the vertical rod 21, providing support for the cutting head and a basis for adjusting the angle.

[0030] First, the clamping assembly 4 is used to fix the cutting head and ensure its stability during the cutting process. When the screw 41 is rotated, the push rod 42 will move back and forth along the screw 41, pushing or pulling the trapezoidal block 43 to move synchronously. The trapezoidal block 43 moves forward and then pushes the sliding plate 45 to slide in a direction. The first clamping block 47 cooperates with the second clamping block 48 to clamp the cutting head of the semi-automatic cutting machine. The elastic telescopic rod 46 is squeezed and clamps the cutting head.

[0031] Subsequently, the adjustment component 3 is set inside the support component 2 to adjust the angle of the movable support rod 22 relative to the vertical rod 21, thereby achieving precise adjustment of the cutting head angle. When the worm gear 311 is rotated, the adjustment rod 32 is driven to move along the positioning groove 34 through the transmission of the worm wheel and worm gear, thereby changing the included angle between the movable support rod 22 and the vertical rod 21, and achieving adjustment of the cutting head angle.

[0032] Finally, by starting the cylinder 8, the piston rod drives the rack 6 to move back and forth. Through the meshing transmission between the gear 7 and the rack 6, the central shaft and the vertical rod 21 are driven to rotate. Since the vertical rod 21 is connected to the movable support rod 22, it can drive the entire support assembly 2 and the cutting head to move in an arc, thereby performing arc bevel cutting on the workpiece.
