Detailed ways

As shown in Fig. 1 to Fig. 3, a kind of multifunctional stainless steel tube inner polishing device of the present utility model comprises at least two fixing frames 1 for fixing the stainless steel tube and a polishing rod 2 for inserting in the stainless steel pipe, and one end of the polishing rod 2 is provided There is an inner grinding head, and the inner grinding head includes a plurality of nuts 21 that are threadedly connected with the grinding rod 2, and each adjacent two nuts 21 are used to clamp the sandpaper 22, and the other end of the grinding rod 2 is provided with a drive that can drive the inner grinding head. The motor 23 that the head rotates along the central axis of the grinding rod 2. The utility model can be applied to the polishing and grinding of the inner side of stainless steel pipes of different sizes. The polishing rod 2 can be polished and polished more stably by fixing the fixing frame 1. The inner grinding head on the polishing rod 2 extends into the stainless steel pipe and passes through the other end The motor 23 of the motor controls the speed of the inner grinding head. Since the edge of the sandpaper 22 held is curved, the faster the speed, the greater the centrifugal force on the sandpaper 22, and the wider the range of the edge of the sandpaper 22, which can be used for larger sizes. The inside of the stainless steel tube is polished and polished; on the contrary, it is suitable for the inner polishing of the stainless steel tube with a smaller size.

In this embodiment, the grinding rod 2 is sheathed with a straightening mechanism 3 capable of reciprocating along the axial direction of the grinding rod 2 and used for straightening the horizontal position of the grinding rod 2 . Because the grinding rod 2 needs to be inserted in the longer stainless steel pipe, therefore, when grinding the end of the stainless steel pipe, the grinding rod 2 has a certain length between the motor 23 and the inner grinding head, which is easily affected by gravity and bent, so that the inner The grinding head cannot work horizontally. Therefore, the device is also provided with a straightening mechanism 3, through which the polishing rod 2 is assisted to be supported. The straightening mechanism 3 includes a moving frame 31, a pulley 32 is provided below the moving frame 31 for reciprocating the moving frame 31 along the axial direction of the grinding rod 2, and at least 3 first supports are evenly distributed around the grinding rod 2 on the moving frame 31 Roller 33 , the rotation axis of the first supporting roller 33 is perpendicular to the central axis of the grinding rod 2 . The support position of the mechanism on the grinding rod 2 is adjusted by the moving frame 31, and the fixing of the grinding rod 2 in the horizontal direction is realized by the clamping of three first support rollers 33, and the setting direction of the first support roller 33, This is to facilitate the continuous advancement of the grinding rod 2, so that the straightening mechanism 3 can continuously move along the central axis of the grinding rod 2.
