Abstract

The utility model discloses a clamp for drilling holes of a steel tube. The clamp comprises a pair of jig frames which are respectively made of a rectangular steel plate, wherein the shapes and the sizes of the two rectangular steel plates are the same; a thread through hole is respectively formed in each end of the long side of each rectangular steel plate; a bolt fastener is installed inside the thread through hole so as to splice the jig frame; vertical semicircular holes in corresponding positions are formed at the abutted seams of the two rectangular steel plates; a complete round hole is formed by each pair of the semicircular holes; and through holes which are opposite to the position of the semicircular holes and are communicated with the semicircular holes are formed in the other long side of each rectangular steel plate. The clamp can be used for clamping a plurality of steel tubes to drill holes, both the precision in drilling the holes in the steel tubes is ensued, and the machining efficiency is improved.

Description

The anchor clamps that are used for steel tube drilling
Technical field
The utility model relates to a kind of auxiliary equipment that applies to the structure steel fabrication field, is specifically related to a kind of anchor clamps for steel tube drilling.
Background technology
In the process of the hole of steel construction, remove a part by car, boring, mill etc. outside lathe finishes, utilize drilling machine and boring bar tool (drill bit, reamer, reamer etc.) to finish by pincers worker greatly.But for steel pipe, especially small-bore steel pipe has certain degree of difficulty in actual bore operation; When particularly drilling hole amount was extremely various, efficient was very slow, and was difficult to guarantee that each has degree of precision.Therefore need a kind of anchor clamps that are specifically designed to steel tube drilling of design, the precision when guaranteeing boring processing, and improve the efficient of processing.
The utility model content
The technical problems to be solved in the utility model provides a kind of anchor clamps for steel tube drilling, to improve precision and the working (machining) efficiency of steel tube drilling.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
The anchor clamps that are used for steel tube drilling comprise a pair of each moulding bed of being made by a rectangular steel plates, and the shape of two rectangular steel plates is identical with size; The two ends of rectangular steel plates long side are respectively equipped with tapped through hole, and bolted is housed in the tapped through hole, with the moulding bed amalgamation; At the assembly commissure of two rectangular steel plates, be provided with the corresponding semicircle orifice longitudinally in position, each forms a complete circular hole to semicircle orifice; Wherein on the other long side of a rectangular steel plates, have the position with respect to semicircle orifice, and the through hole that connects with semicircle orifice.
In the such scheme, the pore size of described each complete circular hole that semicircle orifice is formed is identical with the external diameter of processed steel pipe.
In the such scheme, the center of circle of described semicircle orifice is positioned on the long side of rectangular steel plates, and a plurality of semicircle orifices hollow out engrail with a side of rectangular steel plates.
In the such scheme, described through hole is through to the stage casing of another piece rectangular steel plates by a side of a rectangular steel plates.
The beneficial effects of the utility model are: the utility model firmly many steel pipes of clamping is used for boring processing, has both guaranteed borehole accuracy, has improved working (machining) efficiency again.
Description of drawings
Fig. 1 is the structural representation after the amalgamation of the utility model moulding bed.
Structural representation when Fig. 2 separates for the utility model moulding bed.
Fig. 3 is the location drawing of the utility model moulding bed long side through hole and tapped through hole.
Number in the figure is: 1-bolt, 2-through hole, 3-semicircle orifice, 4-moulding bed, 5-tapped through hole.
The specific embodiment
Describe below in conjunction with 1~3 pair of the utility model of accompanying drawing, should be appreciated that the specific embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
The anchor clamps that are used for steel tube drilling comprise the shape of a pair of each 4, two rectangular steel plates of moulding bed of being made by a rectangular steel plates and big or small identical; The two ends of rectangular steel plates long side are respectively equipped with tapped through hole 5, and it is fastening that bolt 1 is housed in the tapped through hole 5, with moulding bed 4 amalgamations; At the assembly commissure of two rectangular steel plates, be provided with the corresponding semicircle orifice longitudinally 3 in position, each forms a complete circular hole to semicircle orifice 3; Wherein on the other long side of a rectangular steel plates, have the position with respect to semicircle orifice 3, and the through hole 2 that connects with semicircle orifice 3.
Wherein, the pore size of described each complete circular hole that semicircle orifice 3 is formed is identical with the external diameter of processed steel pipe.
Wherein, the center of circle of described semicircle orifice 3 is positioned on the long side of rectangular steel plates, and a plurality of semicircle orifices 3 hollow out engrail with a side of rectangular steel plates.
Wherein, described through hole 2 is through to the stage casing of another piece rectangular steel plates by a side of a rectangular steel plates.
During use, processed steel pipe is held in the circular hole of being made up of semicircle orifice 3, the fixing bolt 1 of going up can be holed by 2 pairs of steel pipes of through hole then.
