Description

Square steel pipe joint boring grab

Technical Field

The utility model relates to the technical field of machining, concretely relates to square steel pipe connects boring grab.

Background

The square pipe is a hollow square section light thin-wall steel pipe, also called steel cold-bending section. The Q235 hot-rolled or cold-rolled strip steel or coiled plate is used as a base material, and is subjected to cold bending processing forming and high-frequency welding to prepare the section steel with the square cross section and the size. Square pipes are often used for manufacturing frameworks, the square pipe frameworks are generally assembled and constructed by welding, riveting or bolts, and the assembling and constructing mode of the square pipe frameworks has the disadvantages of complex process and low efficiency. Adopt the joint to connect convenient and fast, but square pipe joint has reserved the mounting hole when casting, but the mounting hole needs to carry out regular processing before using, just needs to reprocess on the drilling machine.

The drilling machine is a machine tool which mainly uses a drill to machine holes on a workpiece. The drilling machine is characterized in that a workpiece is not moved in the machining process, a cutter rotates and feeds along the direction of a main shaft, and the operation can be manual or motor-driven. Common clamps for fixing workpieces comprise common universal clamps such as bench vices, flat tongs, V-shaped irons and pressure plates, and the clamps have the advantages of firmly and reliably clamping the workpieces but cannot quickly clamp and process square pipe joints.

The utility model discloses a following scheme realizes: a square steel pipe joint drilling clamp comprises a clamp base and a clamp main body, wherein the clamp base is of an L-shaped plate structure, a bolt hole is formed in the middle of a horizontal plate 1 of the clamp base and used for being detachably fixed on a workbench of a drilling machine, a circular through hole 3 is formed in the middle of the upper portion of a vertical plate 2, the clamp main body comprises a step shaft and a positioning piece 4, the step shaft penetrates through and is fixed on the circular through hole 3 of the vertical plate 2, a check ring 5 with a shaft diameter larger than that of the circular through hole 3 is arranged at the joint of the step shaft and the positioning piece 4, a positioning shaft 6 which is located in the circular through hole 3 and is shorter than the circular through hole 3 is arranged in the middle of the step shaft, and a threaded shaft 7 with a shaft diameter smaller than that of the circular through hole 3 is arranged at the front end of the clamp main body; setting element 4 matches for appearance and square pipe joint 8 inner chamber size, and length is greater than the cuboid that square steel pipe connects, and the one end setting of keeping away from the step axle on the cuboid passes the rectangular shape through-hole of cuboid outer wall as placing chamber 9, and the drill bit gets into when breaking through the prefabricated hole on the square pipe joint 8 and places the intracavity 9.

The positioning piece 4 is a hollow cuboid.

Before other side coupling 8 drills, the horizontal plate 1 of anchor clamps base sets up on the workstation of drilling machine, the sectional fixture main part is gone up to vertical board 2, and guarantee placing chamber 9 vertical horizontal plate 1 of anchor clamps main part, add man-hour, with the direct cover of square coupling 8 on cuboid setting element 4, treat on the square coupling 8 and process prefabricated hole and be located and place chamber 9, directly use the drilling rod to aim at prefabricated hole and drill, the drilling rod stretches into after the drilling is accomplished and places chamber 9, later withdraw from the drill bit, other holes on the workable same face of removal square coupling, also can take off the hole of other faces of square coupling back direction of rotation processing, convenient operation is swift.

Has the beneficial effects that: (1) the utility model discloses the anchor clamps base is direct can dismantle to fix corresponding position on the drilling machine workstation, and the anchor clamps main part of setting on the anchor clamps base is used for fixed square pipe joint, and square pipe joint can not rotate wantonly, need not to fix a position once more and can process, can drill by a plurality of faces of quick change.

(2) Circular through-hole phase-match on step axle in the anchor clamps main part and the anchor clamps base needs add man-hour to the square pipe head of different models, only needs to demolish anchor clamps main part and reinstalls, satisfies not unidimensional square pipe head's centre gripping requirement, guarantees the stability and the security of centre gripping.
