Problems solved by technology

[0009] However, this solution is specifically designed to carry out machining operations underwater, and therefore uses elements that must have the characteristics of being able to use them underwater without roaring
So, it can be very expensive

Embodiment Construction

[0020] With reference to these drawings, in particular figure 1 , shows a portable boring machine 100 according to the present invention. The portable boring machine comprises a transmission unit 101 and a central unit 102 . A front view of machine 100 is at figure 2 , where its cross-section A-A and its longitudinal section A'-A' are shown. In more detail, the cross-section A-A of the machine 100 is shown as image 3 shown. The transmission unit 101 comprises an electric motor 103 with an axis of rotation B and a distribution block 104 to support it and transmit the rotation pressurized by the motor 103 onto a tool holder shaft 105 with an axis C of rotation. The flexible mechanical transmission of the motion produced by the electric motor 103 takes place inside the distribution block 104, which comprises a first drive ring gear 106 (whose axis of rotation coincides with the axis of rotation B of the electric motor) and a second guide ring gear 107 ( Its axis of rotatio...

Abstract

A portable boring machine includes:—a transmission unit comprising a first electric motor having an axis of rotation (B) and a distribution block of the motion imparted by said electric motor to a tools shaft supporting means for boring and welding and having an axis of rotation (C);—a centralized unit comprising a supporting shaft for advancement of said tools shaft formed by a hollow cylindrical tube internally comprising an externally threaded screw tube, and a second centralized electric motor adapted to manage said advancement;—means for coupling and decoupling said transmission unit from said centralized unit. The portable boring machine further comprises an advancement system of said screw tube configured for converting the rotary motion imparted by said electric motor in straight linear motion of said screw tube along said axis (C).

Description

technical field [0001] The present invention relates to a portable boring machine. [0002] In particular, the present invention relates to a portable boring machine of the type that is commonly used for boring and welding, that is, access to pivot pin holes or seats, rotating bushings, on the machine or parts thereof, without the need to transport the parts to be stored again in the workshop and without having to place the same part on a stationary tool machine. Background technique [0003] Portable boring machines are known to be able to carry out the operations of boring holes to be serviced, following operations of welding material by welding operations and restoration of original dimensions and tolerances by finishing boring operations. Boring and welding machines can have three or two motors. [0004] One example of a portable boring and welding machine with two motors is described in Italian Patent No. 0001336640 issued November 14, 2006 by SIR MECCANICA SPA. The ...
