Abstract
The utility model relates to a positioning drilling tool for a lightning protection shunting bar ground connector. The positioning drilling tool mainly comprises fastening screws, a drill sleeve, a compressing device, an upper cover and a base, wherein the base is a cube with a groove, the upper cover is located above the base, the upper cover is connected with the base through the fastening screws in a fastening mode, and the drill sleeve is located above the upper cover and fixedly connected with the upper cover. The upper cover and the base are respectively provided with a through hole, wherein the through holes correspond, the through holes and the drill sleeve are located on the same axis, and the axis penetrates a circle center of a semi-circular arc of the sealed end of the groove of the base. The compressing device comprises a compressing bolt and a screwing handle, the compressing bolt penetrates the upper cover and is matched with the threaded through hole of the upper cover, and the compressing bolt corresponds to the groove of the base in position. The positioning drilling tool is simple in structure, a workpiece is positioned by the groove in the base when drilled, and the positioning drilling tool guarantees that the drilling position of the workpiece to be drilled and the drill sleeve are coaxial, can be used for machining a plurality of workpieces simultaneously, is convenient to operate and strong in practicability, can improved efficiency, guarantees accuracy, and reduces cost.
Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of location drilling frock for anti-lightning strike shunt bar bonding sheet.
Background technology
Anti-lightning strike shunt bar bonding sheet is requisite part on most of radome of fighters, is strip, and two ends are semi arch, at semi arch center, two ends with screw hole.The machining process of anti-lightning strike shunt bar bonding sheet is generally that first machinery processes anti-lightning strike shunt bar bonding sheet profile, and then gets out the two ends screw hole.Boring procedure is as follows: scribing by bench worker is found out the screw hole location center line, after using pressing plate clamping location on drilling machine, visual alignment screw centerline hole, get out the two ends screw hole, and its shortcoming is: scribing by bench worker bore position precision is not easy to guarantee, clamping efficiency is low, qualification rate is low.
The utility model content
Technical problem to be solved in the utility model is: a kind of quick, effective, low-cost, high-precision location drilling frock for anti-lightning strike shunt bar bonding sheet is provided.
The technical solution of the utility model is: a kind of location drilling frock for anti-lightning strike shunt bar bonding sheet, and it is characterized by: described frock mainly comprises trip bolt, drill bushing, hold down gag, upper cover, base; Wherein base is for being with reeded cube, plane parallel on the bottom surface of groove and cube, the cross section of groove are rectangle, an end opening of groove, the other end seals and is semicircular arc, and this semicircular arc is consistent with an end profile of anti-lightning strike shunt bar bonding sheet; Described upper cover is positioned at above base, and by trip bolt and base, is fastenedly connected; Described drill bushing is positioned at above upper cover, and with upper cover, is fixedly connected with; Corresponding through hole is arranged on upper cover, base, and through hole, drill bushing are positioned at same axis and axis and pass the center of circle of base groove blind end semicircular arc; Described hold down gag comprises hold-down bolt and swing handle, and described hold-down bolt passes upper cover and with the tapped through hole of upper cover, matches, and hold-down bolt is corresponding with the base groove position.
The beneficial effects of the utility model are: the location drilling tool structure that the utility model is used for anti-lightning strike shunt bar bonding sheet is simple, utilize the groove on base that workpiece is located during boring, the bore position that guarantees workpiece to be processed is coaxial with drill bushing, can process simultaneously many workpiece, easy to operate, practical, can raise the efficiency, guarantee precision, reduce costs.
