[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] Please see Figure 1-5 As shown, the stainless steel pipe welding positioning mechanism includes a fixed support plate 1 and a movable support plate 2. The top of both the fixed support plate 1 and the movable support plate 2 is provided with a clamping component for clamping and fixing the stainless steel pipe.

[0030] The clamping assembly includes a fixed base 3 and a movable upper base 4. The movable upper base 4 is located above the fixed base 3. A clamp 5 for clamping and fixing the stainless steel pipe is installed on the opposite side of the fixed base 3 and the movable upper base 4. Four sets of connecting rods 6 are fixed around the bottom of the movable upper base 4. Through slots are opened on the fixed support plate 1 and the movable support plate 2. The bottom of the connecting rod 6 passes through the fixed base 3 and the through slot and is fixed with a connecting plate 7. Electric push rods 8 are fixed at the bottom of both the fixed support plate 1 and the movable support plate 2. The piston rod of the electric push rod 8 is movably connected to the connecting plate 7.

[0031] A fixed-angle deflection component 9 is provided between the movable support plate 2 and the fixed support plate 1;

[0032] The movable support plate 2 is equipped with a rotating component 10 for adjusting the angle of the clamping component;

[0033] This invention uses a fixed-angle deflection component 9 to rotate the movable support plate 2, thereby adjusting the position of the two sets of clamping components. Then, in conjunction with the rotation component 10, the angle of the clamping components on the movable support plate 2 is adjusted, so that the two sets of clamping components can process and fix the two sets of stainless steel pipes, and the included angle between the two sets of stainless steel pipes can be adjusted to achieve welding and positioning of steel pipes spliced ​​at various angles, thereby improving the flexibility of the device.

[0034] Please see Figure 4 As shown, a set of fixed bases 3 are fixed to the top of the fixed support plate 1, and a rotating shaft 11 is fixed at the center of the bottom of another set of fixed bases 3. The other end of the rotating shaft 11 is rotatably connected to the inside of the movable support plate 2 through a bearing. The through groove on the movable support plate 2 is arc-shaped. The set of fixed bases 3 and the movable support plate 2 are movably connected through the rotating shaft 11, so that the clamping component at the top of the movable support plate 2 can be deflected, which is convenient for the two sets of stainless steel pipes to be obliquely spliced ​​and connected with the other set of clamping components.

[0035] Please see Figure 3 As shown, an I-beam swivel base 91 is fixed at one corner of the fixed support plate 1, and a turntable 92 is fixed at one corner of the movable support plate 2. The turntable 92 is rotatably connected to the outer side of the I-beam swivel base 91. Multiple sets of positioning holes 93 are circumferentially formed on the turntable 92. A through hole 94 is formed on the I-beam swivel base 91, and a positioning pin 95 is inserted into the through hole 94 and the positioning hole 93. By rotating the turntable 92 onto the I-beam swivel base 91, the deflection adjustment of the movable support plate 2 and the fixed support plate 1 can be realized. At the same time, according to the welding requirements, the included angle between the two sets of positioning holes 93 can be specified, and the positioning pin 95 is used to limit and fix the movable support plate 2 to prevent the movable support plate 2 from rotating again and causing the welding angle deviation.

[0036] Please see Figure 4As shown, the rotating assembly 10 includes a worm gear 101 fixed on the outside of the rotating shaft 11, a servo motor 102 fixed inside the movable support plate 2, and a worm 103 meshing with the worm gear 101 fixed on the output shaft of the servo motor 102. The servo motor 102 drives the worm 103, which in turn drives the worm gear 101 to rotate the rotating shaft 11, thereby rotating the fixed base 3 on the top of the movable support plate 2 and adjusting the orientation of the clamping assembly that holds the stainless steel tube.

[0037] Please see Figure 4 As shown, a storage groove 12 is provided on one side of the fixed base 3 and the movable upper seat 4 facing each other. The clamp 5 is located in the storage groove 12. The clamp 5 has a countersunk hole, and a mounting bolt 13 is provided in the countersunk hole. The mounting bolt 13 passes through the clamp 5 and is threaded to the fixed base 3 and the movable upper seat 4 respectively. The clamp 5 is stored in the storage groove 12, which makes it convenient to change the clamp 5 according to the size of the stainless steel pipe. Thus, stainless steel pipes of different sizes can be clamped, welded and positioned. The clamp 5 is fixedly installed using the mounting bolt 13.

[0038] Please see Figure 5 As shown, a movable seat 14 is movably disposed at the center of the connecting plate 7. The two ends of the movable seat 14 are located on the upper and lower sides of the connecting plate 7. A mounting screw 15 is provided at the bottom of the movable seat 14. One end of the mounting screw 15 passes through the movable seat 14 and is threadedly connected to the end of the piston rod of the electric push rod 8. Through the cooperation of the movable seat 14 and the mounting screw 15, the electric push rod 8 and the connecting plate 7 can be movably connected to meet the deflection requirements of the top clamping assembly of the movable support plate 2, and avoid the piston rod of the electric push rod 8 and the connecting plate 7 from not rotating synchronously.

[0039] Please see Figure 1 As shown, a base box 16 is provided at the bottom of the fixed support plate 1 and the movable support plate 2. The fixed support plate 1 is fixed to the top of the base box 16, and the movable support plate 2 is slidably disposed on the top of the base box 16. A limit plate 17 is fixed to one side of the movable support plate 2, and a limit groove 18 is provided on one side of the fixed support plate 1 to engage with the limit plate 17. The fixed support plate 1 and the movable support plate 2 are installed through the base box 16.

[0040] Please see Figure 1 As shown, it also includes a PLC controller 19 installed on the outside of the base box 16. The PLC controller 19 is electrically connected to the electric push rod 8 and the servo motor 102 respectively. The extension distance of the electric push rod 8 and the rotation angle of the servo motor 102 can be programmed in advance through the PLC controller 19 for precise control of the device and to ensure the precision of stainless steel pipe welding.

[0041] When this utility model is in use, when the movable support plate 2 and the fixed support plate 1 are connected by the limiting plate 17 and the limiting groove 18, the two sets of stainless steel pipes to be welded are placed between the fixed base 3 and the movable upper seat 4. Then the electric push rod 8 drives the connecting plate 7 to move down through the movable seat 14. Then the connecting plate 7 moves down the movable upper seat 4 through the connecting rod 6. The clamp 5 is used to fix and hold the stainless steel pipes stably. Then the two sets of stainless steel pipes are connected and then welding can be performed.

[0042] When two sets of stainless steel pipes need to be welded at an angle, the movable support plate 2 is rotated first, and the turntable 92 rotates around the I-beam swivel base 91. Then, the positioning pin 95 is used to position the turntable 92 and the I-beam swivel base 91, clamping the two sets of stainless steel pipes inside the fixture 5. Then, the servo motor 102 is controlled by the PLC controller 19, and the servo motor 102 drives the worm gear 103 to rotate. Then, the worm gear 103 drives the worm wheel 101 to rotate the rotating shaft 11. The rotating shaft 11 drives the fixed base 3 above the movable support plate 2 to rotate, and then the angle of the stainless steel pipes is adjusted to achieve the adjustment of the splicing angle of the two sets of stainless steel pipes.
