Description

一种盘式刹车片内外弧边缘倒角磨床A disc brake pad inner and outer arc edge chamfering grinder

技术领域technical field

本实用新型属于摩擦材料中的盘式刹车片表面加工技术领域,具体涉及一种盘式刹车片内外弧边缘倒角磨床。The utility model belongs to the technical field of surface processing of disc brake pads in friction materials, in particular to a disc brake pad inner and outer arc edge chamfering grinder.

背景技术Background technique

汽车盘式刹车片热压成型后,要对摩擦材料表面进行平面磨削、倒角等机械加工,刹车片的倒角形状及位置有多种,如图1a和图1b所示,常见的倒角位置是在刹车片左右两侧的直线边缘处,且倒角形状为常见的直倒角或斜倒角,这类倒角加工可通过现有的专用倒角机加工完成。After the automobile disc brake pad is hot-pressed, the surface of the friction material should be subjected to surface grinding, chamfering and other mechanical processing. The chamfering shape and position of the brake pad are various, as shown in Figure 1a and Figure 1b, the common inverted The corner position is at the straight edge on the left and right sides of the brake pad, and the chamfer shape is a common straight chamfer or oblique chamfer, which can be completed by the existing special chamfering machine.

近些年,有些新开发车型,尤其是大巴车,其刹车片的倒角位于刹车片前后侧的内外弧边缘处,使得其倒角走向为沿着内外弧的曲线形,如图2a和图2b所示。现有的专用倒角机不适用于此类倒角的加工。目前还没有专门针对此类刹车片内外弧边缘倒角加工的专有设备。有些厂家想到的方法是利用现有通用机械加工机床进行加工,如将刹车片安装在车床卡盘上转动,用车刀分别加工内外弧边缘倒角;或将工件安装在立式铣床工作台上,在特制的刀盘上的不同半径处,分别安装特殊的锥面立铣刀分别加工内外弧的倒角。In recent years, for some newly developed models, especially buses, the chamfers of the brake pads are located at the edges of the inner and outer arcs on the front and rear sides of the brake pads, so that the chamfers are curved along the inner and outer arcs, as shown in Figure 2a and Figure 2. 2b is shown. Existing dedicated chamfering machines are not suitable for this type of chamfering. There is currently no proprietary equipment for chamfering the inner and outer arc edges of such brake pads. The method that some manufacturers think of is to use the existing general-purpose machining machine for processing, such as installing the brake pad on the lathe chuck to rotate, and using the turning tool to process the inner and outer arc edge chamfers respectively; or installing the workpiece on the vertical milling machine table. , At different radii on the special cutter head, special conical end mills are respectively installed to process the chamfering of the inner and outer arcs.

采用上述加工方式,不仅仅是需要定制专用精密夹具,更主要的是受限于现有机床结构与功能,装夹及调整不方便,加工效率低,刀具寿命短。有些大尺寸工件倒角因受限于机床结构而无法加工。Using the above processing method not only needs to customize the special precision fixture, but also is limited by the structure and function of the existing machine tool, the clamping and adjustment are inconvenient, the processing efficiency is low, and the tool life is short. Some large-sized workpiece chamfers cannot be processed due to the limitation of the machine tool structure.
