Embodiment Construction

[0014] Drilling, reaming and reaming guiding device can conveniently, quickly and accurately replace the mold sets for drill bits, reamers and reamers. It is necessary to ensure that the mold sleeve cannot rotate and move up and down with the tool after it is installed. Structure is as accompanying drawing, is identical with common drilling formwork, and fixed sleeve (2) is contained in the hole of drilling formwork (1), cooperates as H7 / n6, determines the position of hole. Positioning plate (4) is fixed on the drilling template (1) with spring washer (5) and bolt (6), is the positioning element of mold cover. The quick-change sleeve (3) is fitted in the hole of the fixed sleeve (2) through the outer circle and the groove of the quick-change sleeve (3) to fit H7 / g6. The quick-change sleeve (3) is rotated so that the facade of the quick-change sleeve (3) contacts the corresponding surface of the positioning plate (4), so as to limit the rotation and up-and-down movement of the...

Abstract

The invention discloses a drilling, expanding and hinge guiding device which is fixedly arranged in a hole of a drilling template in a sleeved mode. A positioning board is fixed on the drilling template through a spring washer and a bolt, and a quick change sleeve is arranged in a hole of a fixed sleeve through the outer circle of the quick change sleeve and a groove. A vertical face of the quick change sleeve is contacted with a corresponding face of the positioning board through rotation. The outer circle of the fixed sleeve is matched with the hole of the drilling template by H7 / n6, and the outer circle of the quick change sleeve is matched with the hole of the fixed sleeve by H7 / g6. The fixed sleeve, the quick change sleeve and the positioning board undergo heat treatment by 58-62HRC. The drilling, expanding and hinge guiding device has the advantages of being capable of rapidly changing mold sleeves used for a drill, a hole expanding cutter and a reamer, and therefore holes with high-precision positions and sizes can be machined. The drilling, expanding and hinge guiding device is low in manufacture cost and high in economic benefit.

Description

technical field [0001] The invention relates to a fixture for machining, especially a guide device for drilling, expanding and reaming. Background technique [0002] Workers in the mechanical industry know that when drilling holes on parts, they need to use drilling jigs to determine the positions of the holes. To process holes with high precision requirements, it usually needs to be drilled, reamed and reamed to complete. Since the holes on the drilling template are designed according to the diameter of the drill bit, the drilling template should be removed during reaming and reaming, and carried out on the processed holes. This may cause the position of the processed hole to be inaccurate or the hole to have a bell mouth defect. Contents of the invention [0003] The purpose of the present invention is to provide a kind of drilling, expanding, reaming guiding device, can all have the mold cover of positioning when drilling, reaming and reaming. [0004] The purpose of...
