[0020] Please see Figure 1-4 This utility model provides a technical solution for a positionable stainless steel pipe butt welding auxiliary feeding mechanism: a positionable stainless steel pipe butt welding auxiliary feeding mechanism includes a device body 1, an outer frame 2 is provided at the upper end of the device body 1, a stainless steel pipe 3 is provided in the middle of the outer frame 2, a clamping and positioning component 4 is provided between the outer frame 2 and the stainless steel pipe 3, a feeding motor 5 is provided inside the device body 1, a drive gear 6 is provided at the output end of the feeding motor 5, a driven gear 7 is provided inside the device body 1, a support frame 8 is provided at the upper end of the device body 1, a welding torch 9 and an infrared sensor 10 are provided at the bottom of the support frame 8, and a control panel 11 is provided on the outer side of the device body 1;

[0021] The clamping and positioning assembly 4 includes an electric push rod 41, a pressure sensor 42 at the output end of the electric push rod 41, a positioning plate 43 at the bottom of the pressure sensor 42, a guide rod 44 at the upper end of the positioning plate 43, a guide sleeve 45 at the upper end of the outer frame 2, and an auxiliary wheel 46 and a movable shaft 47 at the bottom of the positioning plate 43.

[0022] like Figure 1-3As shown, there are two sets of outer frames 2, symmetrically distributed. The middle of the outer frame 2 is provided with a sliding hole that is compatible with the stainless steel pipe 3. A clamping and positioning component 4 is provided between the outer frame 2 and the stainless steel pipe 3. The feeding motor 5 is electrically connected to the control panel 11. The output end of the feeding motor 5 is fixedly connected to the drive gear 6. The drive gear 6 meshes with the driven gear 7. The driven gear 7 is movably connected to the main body 1 of the device. The support frame 8 is fixedly connected to the main body 1 of the device. The support frame 8 is connected to the welding torch 9 by bolts. The infrared sensor 10 is electrically connected to the control panel 11. The control panel 11 is provided with control buttons and a display screen on the outside. The control panel 11 is provided with a control circuit board and a battery inside, which facilitates the position identification of the end of the stainless steel pipe 3 and makes it convenient to feed the stainless steel pipe 3.

[0023] like Figure 3-4 As shown, the number of electric push rods 41 is equal to the number of outer frame 2, and the electric push rods 41 are electrically connected to the control panel 11. The output end of the electric push rod 41 is fixedly connected to the detection end of the pressure sensor 42. The pressure sensor 42 is electrically connected to the control panel 11 and fixedly connected to the positioning plate 43. The bottom of the positioning plate 43 has an arc-shaped structure. The number of guide rods 44 is twice the number of positioning plates 43. The number of guide sleeves 45 is equal to the number of guide rods 44 and the two are compatible. The number of auxiliary wheels 46 is several groups and distributed in an array.

[0024] The working principle of this utility model is as follows: During the use of the feeding mechanism, the stainless steel pipe 3 is inserted into the interior of the outer frame 2. The output end of the feeding motor 5 is controlled by the control panel 11 to drive the active gear 6 and the driven gear 7 to mesh and rotate, so that the driven gear 7 and the outer side of the stainless steel pipe 3 rotate, causing the stainless steel pipe 3 to move until the stainless steel pipe 3 moves to the front of the infrared sensor 10. Then, the clamping and positioning component 4 is controlled by the control panel 11 to clamp and position the stainless steel pipe 3, thereby facilitating the subsequent welding of the welding gun 9.

[0025] It should be noted that, through the setting of the clamping and positioning component 4, when positioning and clamping the stainless steel pipe 3, the output end of the electric push rod 41 controlled by the control panel 11 drives the pressure sensor 42 and the positioning plate 43 to descend, so that the positioning plate 43 drives the guide rod 44 to slide along the inside of the guide sleeve 45, and at the same time drives the auxiliary wheel 46 to contact the outside of the stainless steel pipe 3. At this time, the pressure sensor 42 detects the downward pressure. When the set range value is reached, it feeds back to the control panel 11 and controls the output end of the electric push rod 41 to stop running, thereby clamping and positioning the stainless steel pipe 3. When the stainless steel pipe 3 needs to be rotated for welding, the stainless steel pipe 3 can also be rolled along the outside of the auxiliary wheel 46. The structure is simple, the operation is convenient, and it saves time and effort. It can position stainless steel pipes 3 of different sizes.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
