Abstract

A method for machining a metallic member to provide a finished appearance, the method uses a lathe and a scraping process. A metallic member includes a top portion and a peripheral sidewall, is positioned on the worktable. The worktable is rotated with the metallic member, the lathe tool reciprocates to machine the top portion of the rotary metallic member circumferentially. The lathe tool is moved along a predetermined path relative to the worktable by the moving device 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, 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 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 along a second direction perpendicular to the first direction, the lathe feeding mechanism comprises a sliding saddle, a mounting seat, at least one feeding assembly received in the mounting seat, and a 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 along a third direction substantially perpendicular to the first and second direction reciprocally when processing the metallic member, the sliding saddle is slidably connected to the moving device along the second direction, 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; the mounting seat further comprises a guiding portion mounted on the first side wall, and a sliding portion mounted on the second side wall; 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, 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 and the mounting seat 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 by the at least one feeding assembly 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;
(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; and
(10) applying the worktable to rotate the metallic member along the first axis and a second axis parallel to the second direction to enable the end edge of the peripheral sidewall to face the scraping cutter, and chamfering the end edge by the scraping cutter along a predetermined path, 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 about an axis parallel to the third direction, the peripheral sidewall comprises a plurality of side surfaces arranged in order and adjacent two 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 2 , wherein the step (10) further comprises: rotating the metallic member by the worktable along the second axis upward; chamfering the end edge along the end edge; when the scraping cutter arriving at the corner, driving the scraping cutter by the moving device to adjust a feed direction of the scraping cutter, and rotating the scraping cutter by rotatable driving members to enable the scraping cutter to scrape the corner along the tangent line of the outer surface of the corner; the scraping cutter stopping working and moving the scraping cutter by the moving device away from the metallic member; rotating the metallic member by the worktable along first axis and second axis for a certain angle, moving the scraping cutter by the moving device to contact the metallic member and chamfering the end edge; the scraping cutter chamfering the end edges on the side surfaces one by one, thereby accomplishing chamfering the metallic member.

4. The method of claim 1 , wherein the scraping feeding mechanism is slidably mounted on the sliding saddle along the third direction 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 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 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 1 , wherein the worktable is capable of rotating along multi-axis, in the step (10), the worktable rotates the metallic member along the multi-axis, the moving device moves the scraping cutter simultaneously to enable the scraping cutter to contact and scrape the end edge all the time.

7. The method of claim 1 , wherein in the step (9), the worktable remains still, the scraping cutter moves along a predetermined path to scrape the peripheral sidewall of the metallic member.

8. The method of claim 1 , wherein in the step (9), the worktable rotates the metallic member about the first axis to match with the scraping of the scraping cutter.

9. The method of claim 1 , wherein in the 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.
