一、机床结构简要说明
I. Brief description of structure
本机床为小吨位卧式内拉床，适用于拉削中小零件，如：圆孔、方孔、键槽孔，内花键孔等。机床结构紧凑，造型美观。主要由以下几部分组成。
This machine tool is a light-tonnage horizontal internal broaching machine. It is suitable for broaching medium and small sized parts, such as round hole, square hole, key slot hole, female spline hole, etc. The machine tool is compact in structure and aesthetic in appearance. It mainly consists following parts.
一）床身部分
I) Body section
床身前端装有花盘和接油斗。前部有冲屑冷却装置、照明工作灯、机床操作按钮，下部是冷却箱，并装有冷却泵，收集铁屑的抽屉。油箱与床身联为一体，上置液压系统，下为储油箱。
The front end of the body is installed with the face plate and the oil drip pan. In the front part, it is mounted with cooling device for punching, work light, operating buttons for the machine tool; the lower part is the cooler housing fitted with cooling pump and drawer for collecting iron chips. The oil tank is integrated with the machine body, the upper part is hydraulic system and the lower part is the oil storage tank.
二）液压油缸
II) Hydraulic cylinder
置于后床身的上半部，与床身采用法兰联接。活塞杆与溜板相联，带动溜板工作。www.en-ch.com
The hydraulic cylinder is placed at the upper half of the rear machine body and is coupled with the machine body by flanges. The piston rod is connected with the slide carriage and drives the slide carriage to work.
三）溜板部分
III) Slide carriage
溜板前部与卡刀体相联接，后部与油缸活塞杆相联接，在床身的两滚珠导轨上运动，从而带动拉刀工作。在溜板一侧装有限位碰铁，与限位开关感应，实现机床的拉削与返回功能。
The front part of slide carriage is joined with the swaging clamp, the rear part if connected with the piston rod of the cylinder, it moves on the two ball type guide rail of the machine body, so as to drive the broach to work. In one side of the slide carriage, there is limit cam, response to the limit switch, to realize the broaching and returning function of the machine tool.
四）刀夹头
IV) Tool chuck
安装在溜板的前部，随溜板运动，卡住或松开拉刀，从而对工件进行拉削。（具体结构见附图三）
It is installed in the front of slide carriage and moves along with the slide carriage, it broaches the work piece through clamping or unclamping the broach. (For specific structure, see the attached Fig.3)
