[0002] Laser cutting of pipes has the advantages of high processing efficiency, high cutting precision, and smooth edges. With the improvement of processing requirements, in addition to being able to cut pipes straight, the laser cutting mechanism also needs to have the function of bevel cutting. The laser cutting head in the existing pipe cutting machine only needs to perform straight cutting with the cutting head vertically downward, so the laser cutting head is directly set on the Z-axis slide table. However, when the laser cutting head needs to have the bevel cutting function, the laser cutting head cooperates with the A-axis turntable. However, the Z-axis slide table is generally a flat plate structure, with a thin structure, easy to deform, and poor cooperation accuracy with the A-axis turntable, affecting the processing accuracy.

[0003] It can be seen that the existing technology still needs to be improved. Summary of the Utility Model

[0004] In view of the above deficiencies of the existing technology, the purpose of the present utility model is to provide a bevel pipe cutting assembly, aiming to improve the structural strength of the Z-axis slide table and ensure the precise cooperation between the Z-axis slide table and the A-axis turntable.

[0005] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

A plurality of installation holes are arranged on the vertical plate around the avoidance hole, and installation screws pass through the installation holes and are connected to the main body of the A-axis turntable.

[0007] As a further improvement of the above technical solution, the strengthening module includes two vertical rods arranged on the back of the vertical plate and distributed left and right, and a plurality of horizontal connecting rods for connecting the two vertical rods.

[0008] As a further improvement of the above technical solution, a plurality of the horizontal connecting rods are arranged at intervals from top to bottom.

[0009] As a further improvement of the above technical solution, two vertical cushion strips are arranged on the front end face of the vertical plate and distributed left and right. A vertically extending guide rail is correspondingly arranged on each vertical cushion strip, and the back of the Z-axis slide plate is slidably connected to the corresponding guide rail through a slider.

[0010] As a further improvement of the above technical solution, the Z-axis driving structure includes a top plate disposed at the top of the vertical plate, a Z-axis motor disposed downward on the top plate, a lead screw vertically extending between the two vertical cushion strips, and a lead screw nut movably sleeved on the lead screw. Both ends of the lead screw are installed on the vertical plate through an adapter seat, and the top end of the lead screw is in transmission connection with the Z-axis motor.

[0011] As a further improvement of the above technical solution, bellows covers for protecting the lead screw and the guide rail are connected to both the top and the bottom of the Z-axis slide plate.

Detailed Description of the Embodiment

[0018] The present utility model provides a bevel pipe cutting assembly. To make the objectives, technical solutions and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0019] Please refer to Figure 1 and Figure 2 , the present utility model provides a bevel pipe cutting assembly, including an A-axis turntable, a laser cutting head arranged at the output end of the A-axis turntable, a vertical plate, a strengthening module arranged behind the vertical plate, a Z-axis slide plate slidably arranged vertically on the front end face of the vertical plate, and a Z-axis driving structure for driving the slide plate to move up and down. The rear end face of the vertical plate is set as a precision machining surface near the bottom, and an avoidance hole is opened at the center of the precision machining surface. The A-axis motor on the A-axis turntable passes through the avoidance hole, and the mounting surface of the A-axis turntable fits with the precision machining surface on the vertical plate. A plurality of mounting holes are arranged on the vertical plate around the avoidance hole, and mounting screws pass through the mounting holes and are connected to the main body of the A-axis turntable.

[0020] Compared with the prior art, the bevel pipe cutting assembly provided by the present utility model significantly improves the bearing capacity and anti-deformation ability of the Z-axis slide plate by arranging a strengthening module behind the vertical plate, ensuring the stability and precision of the assembly during bevel cutting operations. Also, by arranging a precision machining surface on the vertical plate, it ensures that the precision machining surface can closely fit with the mounting surface of the A-axis turntable, improving the assembly precision of the A-axis turntable. The mounting screws firmly fix the A-axis turntable on the vertical plate, simplifying the assembly process of the bevel pipe cutting assembly and facilitating future maintenance and component replacement.

[0021] During operation, since the laser cutting head can move up and down along the Z-axis slide plate and cooperate with the rotation of the A-axis turntable, the bevel pipe cutting assembly can not only perform straight cutting on the pipe, but also achieve bevel cutting at complex angles, meeting the requirements of high precision and high efficiency in modern processing.

[0022] Specifically, the strengthening module includes two vertical rods arranged on the back of the vertical plate and distributed left and right, and a plurality of horizontal connecting rods for connecting the two vertical rods. The frame structure composed of the two vertical rods and the plurality of horizontal connecting rods effectively increases the support area on the back of the vertical plate, thereby enhancing the bending strength and torsional stiffness of the entire assembly and ensuring the stability of the structure when bearing heavy loads or dynamic stresses. In addition, the heat generated during the laser cutting process may cause structural deformation. By arranging a strengthening module on the back of the vertical plate, it helps to disperse and conduct heat energy, reduce deformation caused by thermal expansion, and maintain cutting precision.

[0023] It is further understood that the plurality of horizontal connecting rods are arranged at intervals from top to bottom. The interval arrangement of the horizontal connecting rods can ensure that each part of the vertical plate is evenly supported in the vertical direction, avoiding the situation where the local force is too large, making the load distribution of the entire structure more balanced and enhancing the stability of the overall structure.

[0024] In order to ensure smooth movement of the Z-axis slide, two vertical pads are arranged on the front end of the vertical plate, each of which is provided with a vertically extending guide rail, and the back of the Z-axis slide is slidably connected to the corresponding guide rail through a slider. The combination of the guide rail and the slider provides a high-precision linear guide to ensure the straightness and stability of the Z-axis slide when it moves up and down.

[0025] In this embodiment, the Z-axis driving structure includes a top plate arranged on the top of the vertical plate, a Z-axis motor arranged downward on the top plate, a lead screw extending vertically and arranged between the two vertical pads, and a lead screw nut movably sleeved on the lead screw, the two ends of the lead screw are mounted on the vertical plate through an adapter, and the top end of the lead screw is connected to the Z-axis motor in a transmission manner. The combination of the lead screw and the lead screw nut provides high-precision linear motion control, and the Z-axis motor can very accurately control the rise and fall of the Z-axis slide plate by driving the lead screw to rotate, thereby achieving high-precision cutting depth control.

[0026] In order to ensure that the Z-axis slide works smoothly and accurately for a long time, the top and bottom of the Z-axis slide are connected with bellows covers for protecting the lead screw and guide rails. The bellows covers can effectively block dust, metal debris and other contaminants from entering the lead screw and guide rail area, preventing these contaminants from causing lead screw thread wear or jamming.

[0027] In order to reduce the risk of operators accidentally contacting rotating parts, improve operational safety and prevent safety accidents, a shield for protecting the A-axis motor of the A-axis turntable is provided on the vertical pad.

[0028] The vertical plate is provided with a wiring hole, which provides a clear passage for the optical fiber and other cables, avoiding the disorder of the cables and improving the neatness and safety of the equipment. The laser cutting head is provided with an I-shaped optical fiber fixing piece. The I-shaped optical fiber fixing piece can firmly clamp the optical fiber to avoid the optical fiber being pulled or worn when the equipment moves, thereby extending the service life of the optical fiber and reducing maintenance costs.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection or a connection capable of mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements.
