Embodiment Construction

[0029] Such as Figure 1 to Figure 4 As shown, a drilling jig for cylindrical hole machining of the present invention includes:

[0030] The drill phantom body 1 has a rectangular parallelepiped structure. The drilling mold body 1 is provided with a first through hole 2 and a second through hole 3, and the first through hole 2 is bored in the middle of the drilling mold body 1 and the through hole that penetrates from top to bottom is the first through hole 2. The second through hole 3 is the through hole boring and penetrating right and left. The upper end of the second through hole 3 is a V-shaped groove 4, and the lower end is a groove. The V-shaped groove 4 is processed symmetrically with the central axis of the first through hole 2, and the V-shaped groove 4 is a 90-degree V-shaped groove. The workpiece 10 is arranged in the second through hole 3, the width of the second through hole is greater than the diameter of the workpiece 10, and the upper end of the workpiece 10 is...

Abstract

The invention discloses a drilling jig used for cylinder hole machining. The drilling jig comprises a drilling jig body, a drill bushing, a positioning baffle, a positioning threaded shaft, a base plate and screws, wherein the drilling jig body is provided with a first through hole and a second through hole, a V-shaped groove is formed in one end of the second through hole, and a workpiece is arranged in the second through hole and makes contact with the V-shaped groove; the drill bushing is arranged on the first through hole, the first end of the drill bushing is attached to the upper surface of the drilling jig body, and the second end of the drill bushing makes contact with the V-shaped groove; the positioning baffle is arranged on one side face of the drilling jig body; the positioning threaded shaft is arranged at the first end of the positioning baffle; the base plate is arranged below the workpiece; the screws are arranged at the lower end of the drilling jig body and make contact with the base plate. The V-shaped groove is located above, the workpiece is tightly pushed from bottom to top and arranged in a reversely positioned mode, the workpiece is clamped conveniently, positioning is stable, the holes are in close fit with the workpiece in a non-clearance mode, hole drilling is accurate, machining efficiency is high, machining cost is low, and processes are simple.

Description

Technical field: [0001] The present invention relates to the technical field of mechanical processing, in particular to a drilling jig for cylindrical hole processing. Background technique: [0002] Drilling holes on the outer cylindrical surface of cylinders or hollow cylinders of various lengths and diameters has higher position accuracy requirements. The drill bit is not easy to locate, easy to drill, and it is easy to break the tool. The drilling jig is a machine tool fixture used to guide the tool in drilling or reaming the workpiece. Its structural feature is that in addition to positioning and clamping the workpiece, it can also set the drill sleeve according to the position distribution of the processed hole And the drilling template to determine the position of the tool and prevent the tool from tilting during the machining process to ensure the accuracy of the position of the machined hole. The drilling dies currently used for cylindrical hole processing include: fixed...
