[0002] The main purpose of the laser cutting positioning device for stainless steel pipe fittings is to ensure that the stainless steel pipe fittings can be accurately positioned during the laser cutting process, so as to ensure the cutting effect and the dimensional accuracy of the product. The laser cutting device is equipped with a table, and the positioning device is installed on the table with bolts. The laser cutting head starts cutting according to the set path and parameters. The positioning device mainly limits the stainless steel pipe fittings through the support frame.

[0003] Dust easily adheres to the surface of stainless steel pipes, preventing the laser beam from directly reaching the material surface. The laser's penetration power varies in different areas, resulting in uneven cutting lines and affecting the cutting effect. Manually wiping stainless steel pipes also increases labor costs. Therefore, a laser cutting positioning device for stainless steel pipes was designed. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a laser cutting and positioning device for stainless steel pipe fittings:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a positioning device for laser cutting of stainless steel pipe fittings includes a positioning table 1. A threaded rod 2 is installed inside the positioning table 1. A threaded block 3 is fitted onto one end of the threaded rod 2. A U-shaped seat 5 is installed on the top of the threaded block 3. A U-shaped plate 6 is installed on one side of the U-shaped seat 5. A hydraulic cylinder 7 is installed on the top of the U-shaped plate 6. Two clamping frames 8 are installed on the top of the positioning table 1. Silicone pads 9 are installed on the outer surfaces of both clamping frames 8. A first L-shaped plate 10 is fixedly installed on the front of the U-shaped seat 5. A fixing rod 11 is installed inside the U-shaped plate 6. A moving block 12 is fitted onto one end of the fixing rod 11. A second L-shaped plate 13 is installed on one side of the moving block 12. When the stainless steel pipe fitting is pushed towards the clamping frame 8, a moistened water plug 16 continuously rubs against the stainless steel pipe fitting, wiping away dust adhering to its surface and improving the quality of laser cutting.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, each of the two brackets 14 is provided with a water injection plug 16 on one side, and multiple absorbent cotton strips 15 are arranged at equal intervals. The output shaft of the micro motor 4 is connected to one end of the threaded rod 2. The moving block 12 is movably sleeved on one end of the fixed rod 11. The top of one clamping frame 8 is connected to the output shaft of the hydraulic cylinder 7, and the bottom of the other clamping frame 8 is fixedly connected to the top of the U-shaped seat 5. After the micro motor 4 is started, it drives the threaded rod 2, which is connected to its output shaft, to rotate, which in turn drives the threaded block 3 sleeved on it to move left and right, thereby adjusting the position of the two clamping frames 8 and increasing the clamping and positioning range of the stainless steel pipe fitting. After the hydraulic cylinder 7 is started, it drives the clamping frame 8, which is connected to its output shaft, to move up and down.

[0026] Working Principle: The design of the stainless steel pipe laser cutting positioning device aims to ensure precise positioning of the stainless steel pipe during laser cutting, ensuring cutting effect and product dimensional accuracy. The laser cutting device is equipped with a table, and the positioning device is bolted to the table. The laser cutting head begins cutting according to the set path and parameters. The positioning device mainly limits the stainless steel pipe through the support frame. Dust easily adheres to the surface of the stainless steel pipe, preventing the laser beam from directly acting on the material surface. The laser penetration varies in different areas, resulting in uneven cutting lines and affecting the cutting effect. Manually wiping the stainless steel pipe also increases labor costs. Therefore, a stainless steel pipe laser cutting positioning device is designed. The stainless steel pipe is clamped and positioned by two clamping frames 8. The positioning table 1 is installed on the laser cutting device table, applying pressure to the second L-shaped plate 13. The moving block 12 moves up and down at one end of the fixed rod 11, thereby adjusting the position and height of the top bracket 14. The two brackets 14 are respectively positioned relative to the outer surface of the stainless steel pipe. The surfaces are in contact with each other. Water is injected into the interior of the bracket 14 beforehand through the water injection plug 16. The absorbent cotton strip 15 absorbs water and gradually becomes wet, pushing the stainless steel pipe towards the position of the clamping frame 8. The wet water injection plug 16 continuously rubs against the stainless steel pipe, which can wipe away the dust attached to its surface and improve the quality of laser cutting. After starting the micro motor 4, it drives the threaded rod 2 connected to its output shaft to rotate, which in turn drives the threaded block 3 fitted with it to move left and right, thereby adjusting the position of the two clamping frames 8 and increasing the clamping and positioning range of the stainless steel pipe. After starting the hydraulic cylinder 7, it drives the clamping frame 8 connected to its output shaft to move up and down. The top clamping frame 8 gradually approaches the other clamping frame 8, thereby clamping the stainless steel pipe. After the second L-shaped plate 13 moves to the appropriate position, one end of the limiting strip 17 is embedded into the interior of the concave hole 18. The threaded connection between the two can limit and fix the U-shaped plate 6 and the second L-shaped plate 13, ensuring the firmness of the top bracket 14.
