Positioning device for cutting steel pipes

Abstract

The invention discloses a positioning device for cutting steel pipes. The positioning device comprises a handle, a clamping plate, a worktable, a support plate, a strut, a base, a sliding groove, a support plate, an air blower, a screw, an iron rod, a spring, a clamping hole, a clamping plate, an air inlet hole, a screw hole and a clamping groove. The positioning device is provided with the clamping plate, a user can push the clamping plate to move by screwing the handle, the steel pipes are clamped through the clamping groove in the clamping plate, fixation of the steel pipes is facilitated,and cutting is more convenient to achieve; the support plate is arranged and is clamped into the sliding groove, and therefore the support plate can slide on the sliding groove back and forth, the user can identify the lengths of the steel pipes according to the scale on the worktable, and the steel pipes are cut more accurately; and the air blower is arranged, and therefore the air blower can beused for blowing chippings generated in the cutting process out of the sliding groove, and the condition that the chippings are accumulated in the sliding groove and sliding of the support plate is influenced are prevented. The positioning device has the characteristics of being firm in fixation and accurate in positioning.

Description

technical field [0001] The invention relates to a steel pipe cutting device, in particular to a positioning device for steel pipe cutting. Background technique [0002] The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and realize factory-like mechanized construction. The use of steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​the protective layer, saving investment and maintenance costs. [0003] However, the existing steel pipe cutting device still has certain defects in use. Although the existing steel pipe cutting device can cut the steel pipe, it will affect the accuracy of cutting due to vibration during the cutting process, and the existing steel pipe cutting device Due to...
