Description

Technical Field

[0001] This utility model belongs to the field of tooling auxiliary technology, specifically an auxiliary tooling for laser cutting machine to cut pipes. Background Technology

[0002] In modern industrial production, laser cutting machines have been widely used in pipe processing due to their significant advantages such as high precision, high efficiency, and good cut quality, especially in industries with stringent precision and quality requirements, such as aerospace, automotive manufacturing, and precision machining. However, in the actual pipe cutting process, a series of problems arise due to the pipe's own structure and characteristics, which highlights the importance of auxiliary tooling for pipe cutting.

[0003] Most pipes are round, which makes them inherently unstable and prone to wobbling and displacement during cutting. Once the pipe's position deviates, the cutting trajectory cannot precisely match the preset path, ultimately leading to quality problems such as dimensional deviations and uneven cuts. In severe cases, the pipe may even become scrap, resulting in a waste of raw materials.

[0004] In order to overcome the shortcomings of existing technologies, it is urgent to develop a new type of auxiliary tooling for laser cutting machines to cut pipes, so as to improve the accuracy, quality and efficiency of pipe cutting, reduce production costs, and promote the further application and development of laser pipe cutting technology in industrial production. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tool for laser cutting machines to cut pipes, which is used to assist in laser cutting of pipes, has good stability, and is easy to install and fix before use and disassemble and maintain after use.

[0006] This utility model is achieved using the following technical solution: An auxiliary tooling for laser cutting machine for cutting pipes includes a worktable, bolts, a U-shaped support frame, guide blocks, and pipe supports.

[0007] Two identical U-shaped support frames are symmetrically fixed on the workbench. The pipe to be cut is placed between the two U-shaped support frames and supported on at least two pipe supports. Side positioning bolts are symmetrically provided on two opposite sides of the U-shaped support frame, and end positioning bolts are provided on the bottom surface of the U-shaped support frame. The end of the end positioning bolt is equipped with a guide block, which limits the end face of the pipe to be cut.

[0008] More preferably, the U-shaped support frame has threaded holes I on two opposite sides for installing side positioning bolts, and threaded holes II on its bottom surface for installing end positioning bolts.

[0009] More preferably, the guide block has a bolt slot on its back and a guide boss on its front, and the guide block is assembled to the end of the end face positioning bolt through the bolt slot.

[0010] More preferably, the outer diameter of the guide boss is the same as the end face diameter of the pipe to be cut.

[0011] During assembly, first mark the required length of the pipe to be cut on the workbench, then mark the positions for installing the support brackets on both the left and right sides. For the left U-shaped support bracket, screw two side positioning bolts into the threaded holes I at both ends of the support bracket, and screw one end positioning bolt into the threaded hole II on the bottom surface of the support bracket. Then, install the guide block's back bolt slot into the bottom of the end positioning bolt in threaded hole II on the bottom surface of the support bracket. After that, spot weld the support seat with the side positioning bolts, end positioning bolts, and guide blocks installed to the marked position on the left side of the workbench where the U-shaped support bracket is installed. Finally, complete the installation of the right U-shaped support bracket on the workbench in the same order.

[0012] Next, install the pipe to be cut. First, place 2 to 3 pipe supports 5 on the workbench (the placement positions are marked on the workbench). Then, place the pipe to be cut on the pipe supports and align the front end of the pipe with the guide block at the bottom of the guide block in the threaded hole II on the bottom surface of the support frame on the left side of the workbench, and align the rear end with the guide block on the right side. At this time, the guide block at the front end of the guide block is located in the inner diameter of the front end of the pipe, completing the installation of the pipe. Then, tighten the end positioning bolts and side bolts on the support seats on the left and right sides of the workbench downwards to fix the pipe to be cut to the support seats on the left and right sides of the workbench. Then, start cutting the pipe with the laser machine. This utility model makes the cutting process more stable and the pipe is less likely to roll.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This utility model can improve the precision, efficiency and quality of pipe cutting, and also ensure the safety and stability of the processing.

[0014] 2. This utility model can be combined with the pipe's own structure to ensure that the pipe's properties are not damaged during processing.

[0015] 3. This utility model can reduce the production cost of laser cutting.

[0016] This utility model is reasonably designed and enables laser cutting of pipes of different lengths, improving the accuracy, efficiency and quality of pipe cutting, reducing production costs, and ensuring stability during laser cutting, making it less prone to pipe deformation. It has good practical application value. Attached Figure Description

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described clearly and completely below in conjunction with the accompanying drawings.

[0023] This utility model provides an auxiliary tooling for laser cutting machine to cut pipes, mainly including: worktable 1, bolts 2, support frame 3, guide block 4, pipe support 5, etc.

[0024] like Figure 1 As shown, two identical U-shaped support frames 3 are symmetrically fixed on the workbench 1. The pipe to be cut 6 is placed between the two U-shaped support frames 3, and the pipe to be cut 6 is supported on at least two pipe supports 5. Figure 3 As shown, side positioning bolts are symmetrically provided on two opposite sides of the U-shaped support frame 3, and end positioning bolts 201 are provided on the bottom surface of the U-shaped support frame 3. The end of the end positioning bolts 201 is equipped with guide blocks 4, which limit the end face of the pipe 6 to be cut.

[0025] like Figure 3 As shown, the U-shaped support frame 3 has threaded holes I 301 on two opposite sides for installing side positioning bolts, and threaded holes II 302 on its bottom surface for installing end face positioning bolts 201.

[0026] like Figure 2 As shown, the guide block 4 has a bolt slot 402 on its back and a guide boss 401 on its front. The guide block 4 is assembled to the end of the end face positioning bolt 201 through the bolt slot 402.

[0027] like Figure 1 As shown, the outer diameter of the guide boss 401 is the same as the end face diameter of the pipe 6 to be cut.

[0028] During assembly, first mark the required length of the pipe 6 to be cut on the workbench 1, and then mark the positions of the support brackets 3 on the left and right sides. For the left U-shaped support bracket, screw two side positioning bolts into the threaded holes I 301 at both ends of the support bracket 3, and screw one end positioning bolt 201 into the threaded hole II 302 on the bottom surface of the support bracket 3. Then, install the bolt slot 402 on the back of the guide block 4 at the bottom of the end positioning bolt 201 in the threaded hole II 302 on the bottom surface of the support bracket 3. After that, spot weld the support seat 3 with the side positioning bolts, end positioning bolts 201, and guide block 4 installed to the marked position on the left side of the workbench 1 for installing the U-shaped support bracket 3.
