Abstract

一种高效滚刀，主要是在普通滚刀的基础上，在每个刀齿上设有主刀齿和附刀齿，将传统滚刀的刀齿数增加了一倍，具有工作效率高、齿轮加工质量好、刀具使用寿命长和性价比高等优点，适合在滚齿机上广泛使用。

Description

高效滚刀
技术领域
本实用新型涉及滚齿机的一种滚刀，特别是一种滚齿效率更高的滚刀，属于齿轮制造领域。
背景技术
滚刀是最常用的齿轮刀具，每一模数的滚刀可以滚切任意齿数的齿轮，是一种多刃的连续切削的刀具，生产效率较高，但现有滚刀的刀齿数量较少，限制其进一步提高工作效率。
发明内容
本实用新型的目的是为了进一步提高工作效率，设计一种工作效率更高的高效滚刀。
本实用新型的高效滚刀，主要是在每个刀齿上设有主刀齿和附刀齿。对于模数大于8的滚刀，可在主刀齿的顶端中部设有V形分屑槽，附刀齿的顶端两侧设有V形分屑槽。为了便于进刀，可在滚刀的切入端设有10-20度的切削锥。
本实用新型的高效滚刀，由于将传统滚刀的刀齿数增加了一倍，具有工作效率高、齿轮加工质量好、刀具使用寿命长和性价比高等优点，适合在滚齿机上广泛使用。
附图说明
附图1是本实用新型的结构示意图；
附图2是附图1的A向结构示意图；
附图3是附图2中主刀齿的B向结构示意图；
附图4是附图2中附刀齿的C向结构示意图。
具体实施方式
参见附图，图1中的1是刀齿，2是容屑槽，3是切削锥，主刀齿与附刀齿设在同一蜗杆面上。为了便于进刀，在滚刀的切入端设有10-20度的切削锥3。对于左旋滚刀，其切削锥做在右端；对于右旋滚刀，其切削锥做在左端。图2是图1的A向视图，图2中的4是附刀齿，5是附容屑槽，6是主刀齿，7是主容屑槽。附刀齿4设在主刀齿6的后部，在附刀齿4与主刀齿6之间增设有附容屑槽5，附容屑槽5的深度约为主容屑槽7的一半，实际上相当于将现有的一个刀齿改为两个刀齿。对于模数大于8的滚刀，可在主刀齿的顶端中部设有V形分屑槽8，其结构如图3所示，附刀齿的顶端两侧设有V形分屑槽9，其结构如图4所示。由于滚刀的圆周刀排数增加了1倍，可使每个刀齿的切削屑厚度大为下降，可将轴向走刀速度提高到普通滚刀的1-2倍，所以其效率是普通滚刀的1-2倍。滚齿时，齿轮的齿面被滚刀刀齿包络的数量增多，齿面鱼鳞状滚齿波纹较密，齿面的波纹高度大大降低，使齿轮的齿面光洁度高。又因附刀齿同主刀齿一样有效的承担了切削载荷，使每个刀齿的刀尖承受的切削力降低，减少了刀具磨损，延长了刀具使用寿命，同时也延长了刀具重磨的时间间隔，也能有效的提高工作效率。具有工作效率高、齿轮加工质量好、刀具使用寿命长和性价比高等优点，适合在滚齿机上广泛使用。

Claims (3)
