Abstract

The present invention provides a kind of crane angle case connecting hole drilling technique and drilling frock, crane angle to be processed case is arranged on hoistable platform, bushing plate is driven to rise by bushing plate lowering or hoisting gear, positioned by the locating cone and the locating piece inconsistent with two perpendicular end surfaces that match with angle case endoporus, bushing plate is fallen again crane angle case is compressed, feeding depth is controlled finally by bushing plate and is classified completion drilling, compared to the technique of drilling successively after traditional press strip and hold-down bolt fastening, the drilling quality and drilling efficiency of connecting hole are significantly increased.

Description

A kind of crane angle case connecting hole drilling technique and drilling frock
Technical field
The present invention relates to crane angle case drilling manufacture field, and in particular to a kind of crane angle case connecting hole drilling technique And drilling frock.
Background technology
Crane angle case usually requires drilling processing connecting hole, in order to be attached with logical boring cover, existing connection hole drill Technique is cut, as shown in Figures 1 and 2, bent plate 1 is fixed on workbench, by press strip 2 and hold-down bolt 3 by crane angle Case 4 is pressed on bent plate 1, and adjustment drill bit makes it corresponding with the hole position of connecting hole 5, and each connecting hole 5 is processed successively.
Using above-mentioned drilling technique, crane angle case is fixed by press strip and hold-down bolt, in drilling process press strip and Hold-down bolt easily produces loosening, and then causes crane angle case to be rotated around hold-down bolt so that the hole position of connecting hole is inclined Move, influence aligning for drill bit, and then influence the drilling quality of crane angle case connecting hole, meanwhile, each connecting hole is processed successively, is added Work is less efficient.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of drilling quality of connecting hole and that processing efficiency is higher Heavy-duty machine angle case connection hole drilling frock.
To achieve the above object, the technical scheme taken of the present invention is:A kind of crane angle case connection hole drilling frock, bag Hoistable platform, crane angle case, bushing plate and bushing plate lowering or hoisting gear are included, crane angle case is vertical including angle case endoporus and two End face, crane angle case are fixed by positioning device on hoistable platform, and positioner includes determining with what angle case endoporus matched Position cone and the locating piece inconsistent with two perpendicular end surfaces, bushing plate lowering or hoisting gear are fixed on hoistable platform, drill jig lifting dress Putting can drive bushing plate vertically to carry out lifting moving.
The bottom of hoistable platform is provided with horizontal slide rail.
Hoistable platform is electric-controlled type, and bushing plate lowering or hoisting gear is pneumatic type.
Template lowering or hoisting gear is two lift cylinders set along hoistable platform diagonal.
The technical problems to be solved by the invention also reside in the drilling quality for providing a kind of connecting hole and processing efficiency is higher Crane angle case connecting hole drilling technique.
To achieve the above object, the technical scheme taken of the present invention is:A kind of crane angle case connecting hole drilling technique, bag Include following steps:
S1, the crane angle case connection hole drilling frock using said structure, hoistable platform is risen and rises to suitable height;
S2, by bushing plate lowering or hoisting gear by bushing plate rise rise to be adapted to height;
S3, by positioner to crane angle case carry out Set and Positioning, be fixed on hoistable platform, positioner includes The locating cone and the locating piece inconsistent with two perpendicular end surfaces to match with angle case endoporus;
S4, bushing plate height is reduced, crane angle case is pressed on hoistable platform;
S5, drill bit group control feeding depth by bushing plate and are classified completion drilling.
The crane angle case connecting hole drilling technique and drilling frock of the present invention, liter is arranged on by crane angle to be processed case Drop on platform, drive bushing plate to rise by bushing plate lowering or hoisting gear, by the locating cone that matches with angle case endoporus and with The inconsistent locating piece of two perpendicular end surfaces is positioned, then bushing plate is fallen crane angle case is compressed, finally by Bushing plate control feeding depth is simultaneously classified completion drilling, compared to the work of drilling successively after traditional press strip and hold-down bolt fastening Skill, the drilling quality and drilling efficiency of connecting hole are significantly increased.

Fig. 4 is Fig. 3 top view.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
The specific embodiment one of the crane angle case connection hole drilling frock of the present invention, as shown in Figures 3 and 4, including Hoistable platform 1, crane angle case 2, bushing plate 3 and bushing plate lowering or hoisting gear 4, crane angle case 2 include angle case endoporus and two Perpendicular end surface, crane angle case 2 are fixed by positioning device on hoistable platform, and positioner includes matching with angle case endoporus Locating cone 5 and the locating piece 6 inconsistent with two perpendicular end surfaces, bushing plate lowering or hoisting gear 4 be fixed on hoistable platform 1, bore Mould lowering or hoisting gear 4 can drive bushing plate vertically to carry out lifting moving.
The bottom of hoistable platform 1 is provided with horizontal slide rail 7, then hoistable platform 1 rises rise to proper height after, can be along horizontal slide rail 7 move.
Hoistable platform 1 is electric-controlled type, and bushing plate lowering or hoisting gear 4 is pneumatic type, in order to carry out elevating control, ensures connection The precision of hole drilling.
Preferably, bushing plate lowering or hoisting gear 4 is two lift cylinders set along the diagonal of hoistable platform 1, so as to boring Template 3 is steadily lifted, and certainly, in other embodiments of the invention, drill jig lowering or hoisting gear 4 can use other distribution forms It is arranged on hoistable platform 1.
The specific embodiment one of the crane angle case connecting hole drilling technique of the present invention, comprises the following steps:
S1, the crane angle case connection hole drilling frock using said structure, hoistable platform is risen and rises to suitable height;
S2, by bushing plate lowering or hoisting gear by bushing plate rise rise to be adapted to height;
S3, by positioner to crane angle case carry out Set and Positioning, be fixed on hoistable platform, positioner includes The locating cone and the locating piece inconsistent with two perpendicular end surfaces to match with angle case endoporus;
S4, bushing plate height is reduced, crane angle case is pressed on hoistable platform;
S5, drill bit group control feeding depth by bushing plate and are classified completion drilling.
Using above-mentioned processing technology, compared to the technique of drilling successively after traditional press strip and hold-down bolt fastening, connecting hole Drilling quality and drilling efficiency be significantly increased.
