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 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;
wherein the moving device is slidably assembled to the machine support to slide along a first direction while being located above the worktable;
wherein 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;
wherein the at least one feeding assembly drives the lathe tool to move reciprocally along a third direction substantially perpendicular to the first and second directions;
wherein the lathe tool moves according to a depth of cutting required for a machined portion to machine the metallic member circumferentially thereby reducing a reciprocating distance of a movement of the lathe tool relative to the metallic member,
wherein 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 side wall spaced apart from the first side wall, the first side wall and the second side wall together define a receiving space; wherein a through groove is defined in 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 with the first side wall for movement in the third direction, and the main body comprises a holding portion slidably engaged with the second side wall for movement in the third direction, 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 having a peripheral edge, and a peripheral sidewall extending from the peripheral edge of the top portion, the peripheral sidewall comprising an end edge facing away from the top portion;
(3) moving the lathe tool by the moving device to 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 back and forth 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 from rotating, and moving the lathe tool away from the metallic member;
(8) the moving device drives the scraping cutter to contact the peripheral sidewall of the metallic member; and
(9) applying the worktable to rotate the metallic member along an axis parallel to the third direction, moving the scraping cutter along a predetermined path to scrap the peripheral sidewall of the metallic member, and simultaneously controlling a feed of the scraping cutter relative to the metallic member.

2. The method of claim 1 , wherein in step (9), the worktable rotates the metallic member along an axis parallel to the third direction, and the moving device drives the scraping feeding mechanism to move according to the movement of the worktable, thereby enabling the scraping cutter to contact the peripheral sidewall continuously during scraping.

3. 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, and wherein the peripheral sidewall of the metallic member comprises a plurality of side surfaces arranged in order, wherein each adjacent two of the plurality of side surfaces connect to each other at a corner of the metallic member, and wherein step (9) further comprising, wherein when the scraping cutter arrives at the corner, the worktable rotates the metallic member along an axis parallel to the third direction, and the rotatable driving member drives the scraping cutter to scrap the corner, then the worktable rotates the metallic member along the axis parallel to the third direction until the scraping cutter arrives at a side surface adjacent to the side surface that has been scraped, then followed by repeating the machining steps on the adjacent side surface.

4. The method of claim 3 , wherein when the scraping cutter is scraping the corner, the worktable rotates the metallic member along the axis parallel to the third direction, 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.

5. The method of claim 3 , wherein the feeding assembly is received in the mounting seat, and the scraping feeding mechanism is adjacent to the mounting seat.

6. The method of claim 5 , 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.

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

8. The method of claim 5 , wherein the mounting seat comprises two separate guiding portions mounted on the first side wall along the third direction, the tool holder is slidably assembled to the two separate guiding portions mounted on the first side wall.

9. 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 resist the peripheral sidewall.

10. A method for machining 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;
