Abstract

The utility model relates to a to the supplementary tooling, especially a large -scale pipe fitting multi -angle multiposition drilling frock of parts drilling processing, it includes that both ends have the circular -arc metal donor of plane otic placode, the equipartition is equipped with the plane tangent with the arch face on this metal donor outer wall, planar one serves and be equipped with one through the through -hole of this plane with the arch face tangential point at every, and the central line of this through -hole is coincident mutually with the arch face radius through this tangential point. Adopt the utility model discloses the frock can be drilld on the different angles of pipe fitting, different cross -section. Effectively improve the machining precision to improve production efficiency greatly.

Description

Large-size pipe multi-angle multiposition drilling tool

Technical field

The utility model relates to for being equipped the auxiliary process of parts Drilling operation, particularly a kind of multi-angle multiposition drilling tool being applicable to large-size pipe.

Background technology

The boring of pipe fitting generally adopts universal radial drilling machine to carry out, and due to the position in hole and the varied of angle, therefore need before boring to adjust drill press spindle, makes it perpendicular to the surface of pipe fitting, and then hole.The difficult point of this method is the hole that is difficult to ensure to bore perpendicular to the axle center in tube surface and hole by the center line of pipe fitting.

Summary of the invention

The purpose of this utility model is intended to be not orthogonal to tube surface and center, hole not by the center line problem of pipe fitting in order to solve large-size pipe in diverse location different angles boring hole when, proposes a kind of large-size pipe multi-angle multiposition drilling tool.

The multi-angle multiposition drilling tool of the utility model large-size pipe, comprise two ends have plane otic placode arc-shaped metal donor, on this metal donor outer wall, be laid with the plane tangent with arch face, on one end of each plane, be provided with one by the through hole at this plane and arch face point of contact, and the center line of this through hole with coincided by the arch face radius at this point of contact.

When adopting the work of the utility model frock, can this frock and processed pipe fitting be fixed on same workbench, by magnetic drill being placed in the different described plane of this frock, drill bit can be holed by described through hole in the different angles of pipe fitting, by Mobile tool, can hole on the different cross section of pipe fitting.Can ensure that the center line of machining hole is accurately by the center line of pipe fitting, effectively improves machining accuracy, and greatly enhances productivity.

Accompanying drawing explanation

Fig. 1 is the structural representation of the multi-angle drilling frock of the utility model large-size pipe;

Fig. 2, Fig. 3 are working state schematic representations of the present utility model.

Detailed description of the invention

The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.

Embodiment 1

With reference to Fig. 1, a kind of large-size pipe multi-angle multiposition drilling tool, it is characterized in that, comprise two ends have plane otic placode arc-shaped metal donor 1, on this metal donor outer wall, be laid with the plane 3 tangent with arch face, on one end of each plane, be provided with one by the through hole 2 at this plane and arch face point of contact, and the center line of this through hole with coincided by the arch face radius at this point of contact.

Adopt the method for work of the utility model large-scale workpiece heat treatment lifting device as shown in Figure 2,3,

Pipe fitting 5 and frock are fixed on same workbench, can hole in the different angles of pipe fitting on a different plane by magnetic drill 4 is placed, by Mobile tool, can hole on the different cross section of pipe fitting.

Claims

1. a large-size pipe multi-angle multiposition drilling tool, it is characterized in that, comprise two ends have plane otic placode arc-shaped metal donor (1), on this metal donor outer wall, be laid with the plane (3) tangent with arch face, on one end of each plane, be provided with one by the through hole (2) at this plane and arch face point of contact, and the center line of this through hole with coincided by the arch face radius at this point of contact.
