Abstract

A method for machining a metallic member to provide a finished appearance uses a lathe and a scraping process. A metallic member comprising a top portion and a peripheral sidewall is provided, the metallic member is positioned on the worktable. The worktable is rotated with the metallic member, the lathe tool moved backwards and forwards to machine the top portion of the rotary metallic member circumferentially. The lathe tool is moved by the moving device along a predetermined path relative to the worktable to machine curved surfaces of the top portion of the metallic member. The scraping cutter is moved to contact the peripheral sidewall of the metallic member. The scraping cutter is moved along a predetermined path, and the scraping cutter is fed the metallic member to achieve the required shape and finish.

First claim

What is claimed is:

1. A machining method for machining a metallic member using lathing and scraping, comprising:
(1) providing a machine comprising a machine support, a worktable for rotating the metallic member, a moving device, a lathe feeding mechanism, and a scraping feeding mechanism; wherein the worktable is positioned on the machine support; the moving device is slidably assembled to the machine support to slide along a first direction and located above the worktable, the lathe feeding mechanism and the scraping feeding mechanism are slidably assembled to the moving device to slide along a second direction perpendicular to the first direction, the lathe feeding mechanism comprises at least one feeding assembly and a lathe tool, with the lathe tool connected to the at least one feeding assembly, the at least one feeding assembly is configured for driving the lathe tool to move reciprocally along a third direction substantially perpendicular to the first and second directions when processing the metallic member, the lathe feeding mechanism further comprises a sliding saddle slidably connected to the moving device to slide along the second direction, and a mounting seat assembled to the sliding saddle, the mounting seat comprises a frame including a first side wall and a second opposed side wall that cooperatively define a receiving space therebetween; wherein a through groove is defined in the second side wall; wherein the mounting seat further comprises a guiding portion mounted on the first side wall, and a sliding portion mounted on the second side wall; wherein the lathe feeding mechanism further comprises a substantially T-shaped tool holder including a main body and a sliding board, the lathe tool is mounted to the substantially T-shaped tool holder, the sliding board extends through the through groove and is slidably engaged for movement in the third direction with the guiding portion within the receiving space, and the main body comprises a holding portion that is slidably engaged for movement in the third direction with the sliding portion mounted on the second side wall, the scraping feeding mechanism comprises a scraping cutter and is configured for driving the scraping cutter to move along the third direction;
(2) positioning a metallic member on the worktable, the metallic member comprising a top portion and a peripheral sidewall extending from a peripheral edge of the top portion, the peripheral sidewall comprising an end edge away from the top portion;
(3) moving the lathe tool by the moving device to contact the top portion of the metallic member;
(4) applying the worktable to rotate with the metallic member along a first axis-parallel to the third direction;
(5) controlling the lathe tool to move backwards and forwards toward the metallic member to machine the top portion of the metallic member circumferentially;
(6) moving the lathe tool by the moving device along a predetermined path relative to the worktable to machine curved surfaces of the top portion of the metallic member;
(7) holding the metallic member to stop rotating, and moving the lathe tool away from the metallic member;
(8) driving the scraping cutter by the moving device to contact the peripheral sidewall of the metallic member; and
(9) moving the scraping cutter along a predetermined path to scrape the peripheral sidewall of the metallic member, simultaneously controlling a feed of the scraping cutter relative to the metallic member.

2. The method of claim 1 , wherein the scraping feeding mechanism further comprises a rotatable driving member configured for driving the scraping cutter to rotate along an axis parallel to the third direction, the peripheral sidewall comprises a plurality of side surfaces arranged in order and two adjacent of the plurality of side surfaces are connected by a corner, step (9) further comprises when the scraping cutter arrives at the corner, the rotatable driving member rotates the scraping cutter to enable the scraping cutter to scrape the corner along a tangent line of an outer surface of the corner, until the scraping cutter arrives at an adjacent side surface to the side surface that has been scraped, and followed by repeating the machining steps on the adjacent side surface.

3. The method of claim 1 , wherein in step (8), when the scraping feeding mechanism arrives at the peripheral sidewall, the scraping feeding mechanism drives the scraping cutter to slide along the third direction to enable the scraping cutter to arrive at a particular position of the peripheral sidewall.

4. The method of claim 3 , wherein the feeding assembly is received in the mounting seat, and the lathe tool is slidably mounted on the sliding saddle, and the scraping feeding mechanism is adjacent to the mounting seat.

5. The method of claim 4 , wherein the scraping feeding mechanism further comprises a linear driving assembly and a linking board, the linear driving assembly comprises a driving member, a screw leading rod, and a nut, the driving member of the linear driving assembly is mounted on the sliding saddle, the sliding saddle comprises a mounting block, the screw leading rod rotatably interconnects the driving member of the linear driving assembly and the mounting block, the nut is sleeved on and engages with the screw leading rod, the linking board is fixed to the nut and slidably engaged with the sliding saddle, and the rotatable driving member is mounted on the linking board.

6. The method of claim 5 , wherein the sliding saddle comprises two sets of guiding rails along the third direction, and the linking board is slidably assembled to the two sets of guiding rails.

7. The method of claim 4 , wherein the mounting seat further comprises another guiding portion mounted on the first side wall and extending along the third direction, and wherein the tool holder is slidably assembled to the two guiding portions mounted on the first side wall.

8. The method of claim 7 , wherein the sliding board is protruding substantially perpendicularly from the main body, the main body is positioned out of the mounting seat, the sliding board is received in the mounting seat and engages with the two guiding portions, and the lathe tool is fixed to the main body.

9. The method of claim 8 , wherein the feeding assembly comprises two forcers and two stators corresponding to the two forcers, the two forcers are fixed to the mounting seat, the sliding board is positioned between the two forcers, and the two stators are positioned on the opposite surfaces of the sliding board.
