Benefits of technology

Enables safe and efficient machining of large surfaces around the rim of a bore without the need for manual radial adjustment, improving operational safety and versatility in confined spaces.

Problems solved by technology

Portable boring apparatuses, also known as line boring machines, are used for machining machinery parts where it would be impossible or impractical to set up said parts on a conventional machine tool (lathe, milling machine, etc.), primarily because of the relatively large size of the parts.
In this case, to cover the whole surface, it would be necessary to have a facing accessory which extends radially further from the shaft such that the tool would cover the entire surface of the rim to be machined, but this larger facing accessory may not be able to fit into small spaces.
In this case, the radial movement is usually coupled to the rotation of the shaft, or is done manually using a rod held by an operator standing next to the operating machine, putting the worker at risk of injury.

Embodiment Construction

[0058]In the following description of the embodiments, references to the accompanying drawings are by way of illustration of an example by which the invention may be practiced. It will be understood that other embodiments may be made without departing from the scope of the invention disclosed.

[0059]Referring to FIGS. 1 to 5, there is shown a facing accessory 100 for a portable boring apparatus, in accordance with one embodiment. The portable boring apparatus comprises a shaft 150 and rotating means (not shown) for rotating the shaft 150. The portable boring apparatus further comprises securing means (not shown) for temporarily securing the portable boring apparatus to the workpiece such that the shaft 150 extends along a longitudinal axis of the bore of the workpiece.

[0060]In the following description, the term “radially” refers to a direction which is orthogonal to the shaft 150 when the facing accessory is mounted on the shaft 150 of the portable boring apparatus. Specifically, th...

Abstract

There is described a facing accessory for a portable boring apparatus, the accessory comprising: a shaft mounting portion for mounting to a longitudinal shaft of the portable boring apparatus extending along a longitudinal axis; a tool holder secured to the shaft mounting portion and adapted to receive a facing tool thereon, the tool holder comprising at least a telescopic arm for enabling movement of the facing tool towards and away from the shaft mounting portion along a radial axis relative to the longitudinal shaft; and an actuator operatively connected to the second section of the telescopic section for translating the second section relative to the first section along the radial axis.

Description

TECHNICAL FIELD[0001]The invention relates to portable boring apparatuses. More specifically, the invention relates to a facing accessory for a portable boring apparatus.BACKGROUND[0002]Portable boring apparatuses, also known as line boring machines, are used for machining machinery parts where it would be impossible or impractical to set up said parts on a conventional machine tool (lathe, milling machine, etc.), primarily because of the relatively large size of the parts. Boring machine are specifically used to machine an inner sidewall of the bore (an operation known as “boring”) or to machine a rim of the bore (an operation known as “facing”) to repair damage caused by wear in this particular area.[0003]Typically, a portable boring apparatus comprises a shaft, rotating means to rotate the shaft and a bracket adapted to be temporarily secured on a workpiece, near a bore to be machined. One or more tool attachment is secured to the shaft and holds a tool which contacts the workpie...
