端面齿立式专用外拉床方案
Proposal for Special-purpose Face Tooth Vertical External Broaching Machine

一、总体要求
I. Overall requirements

1. 机床采用立式外拉削方式,采用乳化液或油类拉削液湿式加工,回转工作台回转90度人工装卸工件及让刀,专用夹具定位夹紧,用以完成被加工零件的拉削,达到零件的工艺要求。
1.This machine uses an emulsified or oily broaching fluid for wet processing in the manner of vertical external broaching. The swivel table can swivel by 90° for manual work-piece handling and tool back-off; the special clamps can position and clamp the work-piece to finish its broaching up to the process requirements.
2. 工位数量:单工位
2. Number of working positions: one
3. 工厂条件:
3. Factory conditions:
(1) 地基: 整体地基.
(2) 车间高度:6米以上 (机床可埋入地下一部分)
(3) 车间具有提供冷却液的装置.
(4) 车间要求机床安装范围.
(1) Foundation: integral.
(2) Workshop height: over 6m (This machine can be partially buried in the ground.)
(3) The workshop has a device to supply coolant.

二.被加工零件的工艺要求.
II. Process requirements for processed part

1. 工件加工前状态。
1. Pre-processing conditions of work-pieces.
(1) 零件加工前的余量< 3.5mm;
(2) 材料;硬度:HRC22-28以下
(3) 零件的位置精度、尺寸精度、形位公差要求。
(1) Allowance before work-piece processing: <3.5mm;
(2) Material: ______; hardness: below HRC22-28
(3) Position accuracy, dimensional accuracy and tolerance of form and position requirements of the work-piece.
2. 尺寸精度: 符合图纸要求。 
粗糙度:Ra3.2
2. Dimensional accuracy: as per drawing requirements.qnryb.com
Roughness: Ra3.2
3. 位置精度: 符合图纸要求。
3. Position accuracy: as per drawing requirements.

三.机床的布置、结构
III. Layout and structure

1.根据工件工艺要求,工件采用内花键小径及内端面定位,采用液压夹紧。
1.According to the process requirements of the work-piece, the work-piece will be positioned by the minor diameter and inner end face of the internal spline, and clamped hydraulically.
2.机床夹具为一套,回转70度两次拉削。
2.The clamps of this machine are in one set, and broach the work-piece twice within a swivel angle of 70°.
3.拉削采用人工上、下料,工件自动定位、夹紧后,回转工作台回转90度送进拉削区。经过工作台定位、锁紧,工件进入拉削状态。拉削完成后,工作台定位、锁紧松开,回转工作台回转90°,此时工件定位、夹紧不松开,夹具回转轴转动70度后重复上次动作进行第二次拉削。拉削完成后,工件又进入上、下料状态,机床完成一个循环价段。

After being positioned and locked by the worktable, the work-piece will enter the broaching state. After broaching, the worktable will release the work-piece, and the swivel table will swivel by 90°, when the work-piece is not released from positioning and clamping, and the swivel shaft of the clamps will rotate by 70° to repeat the last operation for a second time of broaching. After broaching, the work-piece will enter the charging and discharge state again, and this machine has completed one cycle.
