Abstract

The invention discloses a steel pipe thread burr grinding machine. The steel pipe thread burr grinding machine comprises a lever and a support, wherein the middle of the lever is connected with the upper end of the support through a shaft, one end of the lever is provided with a grinding platform, a first balancing weight is arranged at the other end of the lever, a handle impeller is arranged on the grinding platform, and the weight of the first balancing weight is 10 kg-40 kg. According to the steel pipe thread burr grinding machine, in the using state, a hanging block is placed on a parking table, a second balancing weight is adjusted, so that the pressure of the handle impeller on the thread surface of a steel pipe is at a proper degree, the pressure on the thread on the surface of the steel pipe from the handle impeller is from the gravity of the balancing weights, so that the pressure is unchanged under the condition that the balancing weights are not changed, and the grinding force of the handle impeller on thread burrs at all positions of the steel pipe is the same.

Description

technical field [0001] The invention relates to the field of steel pipe processing, in particular to a steel pipe thread burr grinding machine. Background technique [0002] Exploiting underground oil or natural gas requires the use of steel pipes, which extend down through the steel pipes to transport underground oil and natural gas. Generally, the underground for mining oil or natural gas is very deep, and such long steel pipes are not produced during production. During mining, steel pipes are connected to extend downwards. [0003] Generally, the steel pipes are connected by connecting joints, and the steel pipes and the connecting joints are connected by threads. Therefore, threads need to be processed at the ends of the steel pipes, and the newly processed threads have thread burrs. The existing grinding method for thread burrs makes the contact force between the handle impeller of the grinder and the thread uneven, and the thread is easily worn out, so that the steel ...
