Mechanical fixture used for steel pipe cutting

Abstract

The invention relates to the technical field of mechanical fixtures, in particular to a mechanical fixture used for steel pipe cutting. The mechanical fixture comprises a base. A first worm wheel matched with a first worm is connected to the inner wall of a shell through a rotating shaft. Two threaded blocks are symmetrically arranged on the outer wall of the first worm. Clamping plates are arranged at the end, away from the corresponding threaded block, of each first connection rod and the end, away from the corresponding threaded block, of each second connection rod correspondingly. A secondworm matched with a second worm wheel is arranged between two second bearings. According to the mechanical fixture, the inner wall and the outer wall of a steel pipe can be clamped and fixed at the same time through the multiple clamping plates, the clamping strength is increased, and the fixing effect is improved; the first worm wheel and the first worm each have a self-locking function, the problem that the clamping force is decreased cannot be caused to the clamping plates after the steel pipe is clamped, and the work stability is greatly improved; and the second worm and the second worm wheel can conduct regulation and position fixation according to the length of the steel pipe, and comprehensiveness of use is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical clamps, in particular to a mechanical clamp for cutting steel pipes. Background technique [0002] Most of the construction industry needs to use large steel pipes. The steel pipes produced in the production of steel pipes are of uneven length. If you need steel pipes with the same length, you need to use a cutting machine. During the cutting process, due to the role of the cutting machine, The steel pipe vibrates, and it is difficult to control by manpower. The fixture basically needs to be manually rotated to clamp the workpiece, and the fixture is usually fixed in one place and cannot be moved with the length of the steel pipe. This is also a major disadvantage. , when the workpiece is processed, it is necessary to manually unscrew the fixture, which is not only time-consuming and laborious, but also causes safety hazards, thereby reducing people's work efficiency, and the existing fixture s...
