Abstract

The utility model relates to an angle iron boring mold with an adjustable edge distance, which belongs to the technical field of steel structure producing. The angle iron boring mold with an adjustable edge distance comprises a horizontal base, a vertical base, a bearer, a drill jig, a setting-up screw, a fastening bolt, a variable pitch nut, a support plate and a drill sleeve. The angle iron boring mold with an adjustable edge distance is characterized in that the vertical base and the bearer are fixed on the horizontal base; the horizontal base is provided with the support plate; the vertical base is provided with the variable pitch nut; the variable pitch nut are respectively welded to two ends of the drill jig; the drill jig is provided with the drill sleeve; the bearer conducts tapping and is provided with the fastening bolt. The angle iron boring mold with an adjustable edge distance is advantageous in that the structure is simple, use is convenient, and producing cost is low; boring precision is high, repetitive marking can be prevented, and work efficiency is high; edge distance is adjustable and the drill jig can be saved; the angle iron boring mold is suitable for batch boring of angle iron parts having high-strength bolt holes in the producing of steel structures.

Description

A kind of back gauge adjustable angle iron clamping fixture for drilling

Technical field

The utility model relates to a kind of back gauge adjustable angle iron clamping fixture for drilling, belongs to the manufacture of steel structure technical field.

Background technology

In steel structure member is made, processing to high-strength bolt hole group on the angle steel part, general adopt method of scoring one by one the number of line hole, beat develop and print, the work such as Gui Kong, then hole, but often because the line precision is inadequate, cause the high-strength bolt hole group on the angle steel part in installation, to have the situation that the hole site deviation is large, punching rate is low, and identical parts repeated number hole, the waste in man-hour caused.

Summary of the invention

The purpose of this utility model is in order to solve in the manufacture of steel structure construction, angle steel part high-strength bolt hole group exists in the line of number hole that the hole site deviation is large, punching rate is low, the shortcoming in identical parts repeated number hole, provide a kind of simple in structure, back gauge adjustable angle iron clamping fixture for drilling easy to use, that cost of manufacture is lower.

The purpose of this utility model is realized by following mode:

The utility model comprises horizontal base, vertical pedestal, bearing, drill jig, setting-up screw, fastening bolt, adjusting screw nut, gripper shoe, drill bushing, it is characterized in that: vertical pedestal and bearing are fixed on the horizontal base, and at horizontal base gripper shoe is installed, on the vertical pedestal adjusting screw nut is installed, setting-up screw is welded in the drill jig two ends, drill bushing is installed on the drill jig, and the bearing tapping also is equipped with fastening bolt.

The utility model has the advantages that: simple in structure, easy to use, cost of manufacture is low, and borehole accuracy is high, avoids repeating line, high efficiency, and back gauge is adjustable, saves drill jig.Be applicable to have in the structure steel fabrication angle steel parts batch boring in high-strength bolt hole.
