Description

齿盘滑爪螺旋槽加工装置
技术领域
本发明涉及一种机械技术，具体为一种齿盘滑爪螺旋槽加工装置。
背景技术
在金属加工、木器加工中，有许多设备的主轴上都有夹盘，用来装夹工件。夹盘的主要零件为齿盘和齿盘滑爪，齿盘的端面上加工有等螺距端面螺旋齿，端面螺旋齿沿径向的螺距为固定值，整条螺旋齿的曲率半径是变化的，越靠近齿盘圆心，曲率半径越小，越远离齿盘圆心，曲率半径越大。与齿盘配合的零件是齿盘滑爪，齿盘滑爪上加工有螺旋槽，螺旋槽与齿盘端面上的螺旋齿配合。在使用过程中，齿盘滑爪和齿盘相对转动的同时，齿盘滑爪还要沿齿盘径向移动，以夹持不同直径的工件。由于齿盘上的螺旋齿为等螺距、变曲率半径，所以，齿盘滑爪上的螺旋槽，必须保证既能和齿盘中心处、曲率半径小的螺旋齿配合，也能和齿盘周边处、曲率半径大的螺旋齿配合，与齿盘端面螺旋齿配合间隙过小会影响滑动，与齿盘端面螺旋齿配合间隙太大会影响夹盘的最终精度，所以，齿盘滑爪上的螺旋槽具有一定的特殊性，其外形尺寸和加工方法都成了影响夹盘加工的主要因素。齿盘滑爪上的螺旋槽通常通过数控铣床，采取模拟方法单件加工，或者多件车削后再单件修复，不但加工效率低，而且加工精度差。
发明内容
本发明的目的在于提供一种加工装置，一次装夹多件齿盘滑爪，多件齿盘滑爪成组加工，按同一车削轨迹，先后两次车削，完成齿盘滑爪上的螺旋槽加工，不但加工效率高，而且还能有效地控制齿盘滑爪与齿盘的配合间隙。
为实现上述目的，本发明采用了以下技术方案：
齿盘滑爪螺旋槽加工装置,主要由主体、偏心轴、顶销、弹簧、定位销组成，主体的前端面上设置有四条径向的T形槽，T形槽内用于装夹工件齿盘滑爪，主体中部设置有四个径向的偏心轴，偏心轴的位置与T形槽对应，偏心轴的前面设置有与之配合的顶销，顶销外圆面设有弹簧，偏心轴与主体配合处设置有定位销，在工件齿盘滑爪的背面上设置两个轴向工艺孔A和B，两个工艺孔的距离等于螺旋槽（齿）螺距的倍数，当顶销顶在工艺孔B中时，齿盘滑爪应处于工作时的最小夹持直径处，当顶销顶在工艺孔A中时，齿盘滑爪应处于工作时的最大夹持直径处。
加工齿盘滑爪螺旋槽时，主体的后部装夹在车床夹盘中，将齿盘滑爪插入T形槽内，顶销顶在工艺孔B中，旋转偏心轴锁紧顶销，按齿盘滑爪螺旋槽设计要求设置车刀走刀参数，车削齿盘滑爪螺旋槽，然后顶销再顶在工艺孔A中，按原走刀参数对齿盘滑爪螺旋槽进行第2遍车削，完成加工。
本发明对齿盘滑爪螺旋槽的加工，一个工位两道工序就能完成，加工效率高，并且加工精度高。
附图说明
图1为本发明结构图，
图2为图1的俯视图，
图3为图1的右视图。
图中：1、主体，2、偏心轴，3、顶销，4、T形槽，5、弹簧，6、齿盘滑爪，601、工艺孔A，602、螺旋槽，603、工艺孔B，7、定位销。
具体实施方式
下面以实施例结合附图，对本发明作进一步说明。
下面结合附图对本实施例进行说明：主体采用45#钢，通过车削、铣削、钻削工序加工；偏心轴采用45#钢，通过车削、钻削、冲孔加工完成；顶销采用45#钢，采用车削加工完成。定位销采用45#钢，采用车削加工完成；弹簧采用弹簧钢65Mn。定位销采用45#钢，通过车削加工完成。工作时，主体的后部装夹在车床夹盘中，将齿盘滑爪插入T形槽内。
