Grinding mechanism applied to grinding inner wall of taper pipe

Abstract

The invention discloses a grinding mechanism applied to grinding inner wall of a taper pipe. The grinding mechanism comprises a bottom frame, a support seat, an axial driving device, a screw rod and anut, wherein the support seat is fixed at one end of the bottom frame; two support components are arranged on the bottom frame side by side; the support components are used for supporting a taper pipe; the axial driving device is arranged at one side of the support seat; one end of the screw rod is fixed at the other side of the support seat; a screw thread lifting angle of the screw rod is larger than a screw thread self-locking angle; and the nut is connected with the screw rod in a threaded way; the nut sleeves a rotating shaft, the outer wall of the rotating shaft is provided with three inner wall grinding devices at intervals in the circumferential direction, the axial driving device is used for driving the nut to move in the axial direction, each inner wall grinding device comprisesa grinding assembly and two three-stage spring telescopic pieces, each two three-stage spring telescopic pieces are fixed on the rotating shaft side by side, and each grinding assembly is connected with the free ends of the corresponding two three-stage spring telescopic pieces. According to the grinding mechanism, grinding mechanization operation can be realized, grinding efficiency is improved,and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a grinding mechanism applied to grinding the inner wall of a tapered tube. Background technique [0002] The tapered pipe is spliced ​​by pipes of different diameters, and there will be defects such as weld bumps, welding slag and rust spots during welding at the joint of two pipes with different diameters, and the inner wall surface of the tapered pipe is relatively rough. In order to solve these problems, the inner wall of the pipeline is often polished manually with a hand-held grinding tool, which has low grinding efficiency and high labor intensity. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a grinding mechanism for grinding the inner wall of a tapered tube. [0004] To achieve the above object, the specific scheme of the present invention is as follows: [0005] A grindin...
