Description

加工机动车摩擦片的专用机床Special machine tool for processing friction plates of motor vehicles 技术领域Technical field
本发明涉及一种机床,尤其涉及一种加工机动车摩擦片的专用机床。The invention relates to a machine tool, in particular to a special machine tool for processing a friction plate of a motor vehicle.
背景技术Background technique
机动车刹车是通过刹车制动鼓和刹车制动蹄铁上的摩擦片摩擦产生的摩擦力来实现的。使用传统的机床(参见图3)加工摩擦片时,先将已组装在一起的摩擦片与制动蹄铁安装到专用夹具上(专用夹具已固定在机床主轴上)。加工时,机床主轴旋转,带着工件(即摩擦片)旋转。机床滑板移动,带着刀具,沿着摩擦片轴线移动,刀具切削摩擦片外圆,使其外圆成为圆柱形。使这种方法加工摩擦片时,摩擦片处于旋转状态,在离心力的作用下,摩擦片有向外张开的趋势。加工时摩擦片的外圆呈圆柱形,而当摩擦片停止旋转时,离心力消失,则摩擦片的外圆出现变形,不再是精度较好的圆柱形。将这样的摩擦片安装到机动车的制动鼓内,机动车行驶时摩擦片是不转动的。机动车刹车时摩擦片张开,摩擦片外圆与制动鼓内孔接触时其摩擦面接触率低,将影响车辆刹车效果。Motor vehicle brakes are achieved by friction between the brake drum and the friction plates on the brake shoes. When machining a friction lining with a conventional machine (see Figure 3), the assembled friction linings and brake shoes are first mounted on a special fixture (the special clamp is fixed to the machine spindle). During machining, the machine tool spindle rotates and rotates with the workpiece (ie, the friction lining). The machine tool slides and moves with the tool along the axis of the friction plate. The tool cuts the outer circumference of the friction plate to make the outer circle cylindrical. When the friction plate is processed by this method, the friction plate is in a rotating state, and under the action of the centrifugal force, the friction plate has a tendency to open outward. When the friction plate is rotated, the outer circle of the friction plate is cylindrical, and when the friction plate stops rotating, the centrifugal force disappears, and the outer circle of the friction plate is deformed, which is no longer a cylindrical with high precision. Such a friction lining is mounted in the brake drum of the motor vehicle, and the friction lining does not rotate when the vehicle is running. When the motor vehicle brakes, the friction plate is opened, and the outer surface of the friction plate is in contact with the inner hole of the brake drum, and the friction surface contact rate is low, which will affect the braking effect of the vehicle.

The column 1 is vertically connected to the spindle box 9. The spindle box 9 is fixedly mounted with a spindle motor 10, and the spindle box 9 is also connected to the spindle 8 with a spindle 8 and a spindle motor. The transmission is connected, the main shaft 8 is vertically disposed, and the lower end of the main shaft 8 is fixedly connected with the tool holder 7. The tool holder 7 corresponds to the tooling 4. The tool holder 7 is located above the tooling 4. The tool holder 7 is fixedly connected with the friction plate 5 Tool 6.
在本实施例中,所述刀架7为开口向下的“U”型。所述刀具6安装在刀架7的内侧。In the present embodiment, the tool holder 7 is of a "U" shape with an open downward. The cutter 6 is mounted inside the tool holder 7.
工作台3横向活动连接在底座2上。底座2固定安装有工作台进给电 机12,工作台进给电机12与工作台3传动相连。立柱1固定安装有主轴箱进给电机11,主轴箱进给电机11与主轴箱9传动相连。The table 3 is laterally movably connected to the base 2. The base 2 is fixedly mounted with a table feed motor 12, and the table feed motor 12 is connected to the table 3. The column 1 is fixedly mounted with a headstock feed motor 11, and the headstock feed motor 11 is connected to the spindle box 9.
在本实施例中,刀具的两个自由端均分别开设有方孔,方孔的开口朝向所述主轴,刀具安装在其中一个方孔内,另一个方孔内安装有配重块。In this embodiment, the two free ends of the cutter are respectively provided with square holes, the opening of the square hole faces the main shaft, the cutter is installed in one of the square holes, and the other square hole is installed with the weight.
进一步的,刀具所在的方孔外侧的刀具螺纹连接有螺钉,螺钉的里端顶在刀具的外端。主轴的皮带轮处安装有主轴定位感应开关。Further, the tool outside the square hole where the cutter is located is screwed with a screw, and the inner end of the screw is placed at the outer end of the cutter. A spindle positioning sensor switch is mounted on the pulley of the spindle.
使用本发明加工机动车摩擦片时,先将已与制动蹄铁组装在一起的摩擦片安装到专用夹具上(夹具已安装到机床工作台上),将工作台移动到机床主轴下部,启动旋转主轴,主轴上的刀架和切削刀具绕摩擦片的外圆旋转。同时,主轴箱自摩擦片的一端沿摩擦片外圆的轴线方向向另一端进给移动(即进给运动)。在此过程中,将摩擦片外圆加工成圆柱形。When the motor vehicle friction plate is processed by the invention, the friction plate which has been assembled with the brake shoe is first mounted on a special fixture (the clamp has been mounted on the machine table), and the table is moved to the lower part of the machine tool spindle to start Rotating the spindle, the tool holder and cutting tool on the spindle rotate around the outer circumference of the friction lining. At the same time, the headstock is fed from one end of the friction lining to the other end along the axial direction of the outer circumference of the friction lining (ie, the feed motion). In this process, the outer circumference of the friction plate is processed into a cylindrical shape.
使用本发明加工机动车摩擦片最主要的特点是:在加工中,摩擦片是固定的,不旋转的,旋转的是切削用的刀具。The most important feature of using the invention to process a friction plate of a motor vehicle is that during machining, the friction plate is fixed, non-rotating, and rotating is a cutting tool.
在本发明中,刀架的形状呈“U”形,两侧各有一个方孔,这种形状相对于主轴的轴线对称,旋转时平衡性能好,加工时在一个方孔内安装刀具,另一个方孔内安装与刀具重量相等的配重块,使刀架整体平衡,可以消除因刀架不平衡造成的振动。刀架上的方孔截面尺寸为32mm×32mm,安装的刀具截面尺寸也为32mm×32mm,较传统加工方法所使用的刀具截面尺寸(25mm×25mm)要大,刚性强。刀具后侧设有一个螺钉,可按所加工磨擦片的直径尺寸确定刀具里端伸出方孔的长度,对刀具伸出的长度进行微调。In the present invention, the shape of the tool holder is "U"-shaped, and each side has a square hole. The shape is symmetrical with respect to the axis of the main shaft, and the balance performance is good when rotating, and the tool is installed in one square hole during processing, and A counterweight equal to the weight of the tool is installed in a square hole to balance the tool holder as a whole, which can eliminate the vibration caused by the imbalance of the tool holder. The square hole section size on the tool holder is 32mm × 32mm, and the installed tool cross-section size is also 32mm × 32mm, which is larger than the tool cross-section size (25mm × 25mm) used in the traditional processing method, and the rigidity is strong. A screw is arranged on the back side of the tool to determine the length of the protruding hole at the inner end of the tool according to the diameter of the processed friction piece, and to finely adjust the length of the tool extension.
加工时,在该机床的工装上一次安装两件磨擦片,两件磨擦片之间大概有50~100mm(不同的工件该尺寸有所变化)的空档,加工完磨擦片表面,主轴停止旋转,刀具返回时,由于刀具不具备沿直径方向退刀功能,因此可能会造成刀具划伤已加工的磨擦片表面,这是不允许的,然而这种现象 出现的机率却很大,所以,本机床在主轴皮带轮处安装了主轴定位感应开关,使主轴具有定位功能,能使刀具准确停在没有磨擦片的位置,避免了刀具返回时划伤磨擦片已加工完的表面。During processing, two pieces of friction plates are installed on the tooling of the machine tool. There is about 50-100mm between the two friction pieces (the size of the different workpieces varies). After the surface of the friction plate is processed, the spindle stops rotating. When the tool returns, since the tool does not have the function of retracting in the diameter direction, it may cause the tool to scratch the surface of the processed friction plate. This is not allowed, but the probability of this phenomenon is very large, so this is The machine tool is equipped with a spindle positioning sensor switch at the spindle pulley, so that the spindle has a positioning function, which can accurately stop the tool in the position without the friction plate, and avoid scratching the surface of the friction plate that has been processed when the tool returns.
