Benefits of technology

The present invention provides a tool that can be attached to a robotic arm for use in machining operations. The tool is compact and can access hard-to-reach spaces. It has a frame that can be connected to the robot arm and a foot plate that can be securely attached to the workpiece. The tool is positioned accurately using an attachment system and locking means. The invention also includes an electromagnet system to provide resistance and damping of movement between the plates. The tool is suitable for drilling and can accommodate jerky movements while maintaining precise positioning. The invention allows for a compact and flexible tool to be easily attached to a robotic arm and used in machining operations.

Problems solved by technology

Regardless of the mounting arrangement and the requisite reaction member, the issue of traversing the machining tool relative to the workpiece and with respect to its mounting, in confined spaces, is problematic.

Embodiment Construction

[0088]A drilling tool 10 comprises a frame 12 that has a fore plate 14 and an aft plate 16 connected together by limbs 18. The plates 14, 16 are rounded squares, so that there are four limbs 18. At least one of the limbs incorporates a mounting flange 20 for connection to a robot arm (not shown).

[0089]Opposing corners 14a,b of the fore plate 14 and 16a,b of the aft plate 16 incorporate sleeve bearings 22 through which a pair of pillars 24,26 slide. The pillars 24, 26 are fixed on a yoke 28 on which is also mounted a tool motor 30. The tool motor 30 has a body 32 that is substantially cylindrical and drives an armature (not shown) about a longitudinal axis 50 of the tool 10. A chuck 34 receives a drill bit 36 to be driven by the motor 30 for drilling holes in a workpiece (not shown).

[0090]In drilling holes, it is of course necessary to advance the drill bit 36 in the direction of the hole it is drilling, which is in the direction of axis 50 in FIG. 1. It is of course feasible that a ...

Abstract

A machining tool comprises a frame mounting an extendable yoke slidable with respect to the frame in a first direction through one or more mounting pillars. A tool motor is mounted on the yoke. A drive mechanism for the yoke is also mounted in the frame, with a drive motor to drive the yoke drive mechanism. A belt is between pulleys on the drive motor and mechanism to transmit drive between them. A rotatable sleeve is around the tool motor and on which sleeve the belt engages on opposite sides of the tool motor, whereby the tool motor can extend between the drive motor and mechanism, thereby resulting in a compact arrangement of the tool.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present Application is a divisional of U.S. patent application Ser. No. 13 / 389,435 titled “Remote Confined-Space Machining, and Positioning and Securing Arrangement,” filed Feb. 7, 2012, U.S. Pat. No. 8,267,188 issued Sep. 18, 2012, which is a national stage of International Patent Application No. PCT / GB2010 / 051315, titled “Remote Confined-Space Machining, and Positioning and Securing Arrangement,” filed Aug. 9, 2010, which claims priority from Great Britain Patent Application No. GB0913830.6, filed Aug. 7, 2009, the contents of which are incorporated in this disclosure by reference in their entirety.BACKGROUND[0002]This invention relates to a system for positioning and holding a machine for working in a confined space at a distance from a support base. It relates to means rendering the machine compact, but also secure in a correct position. In another aspect, it relates to mounting structure being an arrangement of a mechanism for pe...
