Abstract

The present invention relates to an apparatus which can machine all sorts of shafts for power delivery, all sorts of collector rings for a generator, all sort of crank shaft main journals and crank pins of an engine, which are irregularly worn out, very efficiently, and a method thereof. More specifically, according to a machining apparatus and a machining method of the present invention, only one of two tool installation parts can be made to move by controlling a screw thread direction and a rotation direction of a lever while a sprocket able to be installed by being divided into two parts on a machining shaft is rotated by a chain. Also, shaft machining can be performed while the two tool installation parts move in an equal or opposite direction at the same time in a fixed amount. Machining time can be reduced by attaching an equal tool to the two tool installation parts and then performing machining at the same time. If different tools are attached to the two tool installation parts, different works can be done at the same time. If a dividable ring type connection part capable of connecting the two tool installation parts is attached, the two tool installation part can be moved by rotation of the lever and screw thread pitch in a fixed amount. If a long male screw bolt and the lever are detached, the machining apparatus can machine a surface of a shaft by pushing a side of the ring type connection part using a hand of a person or a position control part.

In order to fasten these two pairs of half sprockets to the original full pair of sprockets A pair of half sprockets which are divided into two halves and two circular rods are fastened in parallel to the axis and the circular rods are inserted and moved along the working axis to locate tool mounting portions for machining the surface of the working shaft, This type of tool And a long male threaded bolt having a thread is connected to the sprocket in a direction parallel to the machining axis, and the rotation of the long male threaded bolt Wherein a gear type lever is fastened to the end of the long male threaded bolt and a pair of sprockets which are integral with each other are rotated by the chain, The mounting part can move only one tool mounting part by adjusting the screw thread direction and the rotation direction of the lever and also can perform the axial machining while the two tool mounting parts move simultaneously in the same or opposite direction by a certain amount, Simultaneous machining by attaching the same tool to the tool mounting part When a split type ring type connecting rod capable of connecting the two tool mounting portions is attached, the pair of complete sprockets can be connected to the chain When the long male screw bolt and the lever are used, the tool can be moved by a certain amount by the rotation of the lever and the pitch of the screw thread. When the long male screw bolt and the lever are detached, Is a machining device and a machining method that can process the surface of a shaft while pushing the side of a ring-shaped connecting rod by using a hand or a ring-type position adjuster.

Through the above-mentioned problem solving means, the surfaces can be precisely machined without detaching and rotating the various power transmission shafts, collector rings for generators, main journal of the engine crankshaft, crank pins, and the like.

In addition, since the present invention has a tool mounting portion capable of attaching a tool to each pair of two half sprockets, which are installed in two halves on the working shaft, if the same tool is attached while a pair of complete sprockets are being rotated by the chain, It is possible to shorten the time, and by attaching different tools, there is an advantage that different operations can be performed at the same time.

When a split type ring-type connecting rod capable of connecting the two tool mounting portions is attached, when the pair of full sprockets are used with the long male screw bolt and the lever connected to the tool mounting block while being rotated by the chain, When the long male threaded bolt and the lever are detached, the surface of the shaft is machined while pushing the side of the ring-shaped connecting rod by using a position adjuster for a human hand or a ring-shaped connecting rod. There is an advantage to be able to do.
