An angle steel opening fixture

Abstract

An angle steel hole opening fixture belongs to the field of transformer production, including a base, a pressure block, an angle steel and a butterfly nut. The main structures of the base and the pressure block are in a right-angle shape, the pressure block is installed on the base, and the angle steel is located between the pressure block and the base In between, the base is installed on the bench top of the bench drill, and the wing nut is installed on the base. The base includes a lower corner block, a lower back pull plate, a lower bottom pull plate, a column, an ear piece, a lower inclined pull plate, a screw rod and a sleeve, the lower corner block has a pair, and a lower back pull rod and a lower bottom pull are used between a pair of lower corner blocks Plate connection, the bottom of a pair of lower corner blocks each has a column, the bottom of the column has a pair of lugs, and the front end of the horizontal plate of a pair of lower corner blocks has a downward inclined stay plate inclined at 45°. The pressing block includes an upper corner block, an upper back pull plate, an upper bottom pull plate, an upper oblique lug, an upper inclined pull plate, a round table and a guide rod. The plate is connected with the upper bottom pull plate, and the front ends of the horizontal plate of a pair of upper corner blocks are respectively connected with an upward slanting lug inclined at 45°.

Description

technical field [0001] The invention belongs to the technical field of transformer production, and in particular relates to a jig for opening holes in angle steel. Background technique [0002] In the manufacturing process of transformer box, angle steel is often used as box strengthening structure, and it is usually necessary to pre-drill holes on the angle steel to facilitate the connection of angle steel. The drilling operation itself can usually be completed by common drilling machine or bench drill. The feature is that it is difficult to fix the angle steel when opening the hole, which brings a lot of trouble to the on-site operators. The production site needs a special angle steel opening fixture. Contents of the invention [0003] The present invention provides a jig for opening holes in angle steel to solve the above-mentioned problems in the background technology. [0004] The technical problem solved by the present invention adopts following technical scheme to...
