Abstract

本实用新型公开了一种用于加工汽门杆的夹具,该夹具包括后孔和与后孔相通的夹持孔,所述夹持孔的长径比为1:10。本实用新型夹持孔长径比由原来的1:8改为1:10,有效径增长解决二端加工的误差,夹持孔增长直线度更高,产品的合格率大大增加。

Description

一种用于加工汽门杆的夹具
技术领域
 本实用新型涉及机械加工领域,具体地说是用于加工汽门杆的夹具。
背景技术
原有汽门杆加工的夹具夹持孔长径比为1:8,产品设计要求装夹精度(引出40mm)跳动在0.002mm以内,原夹持孔长度为40mm,夹持孔过短,使产品精度不能达到要求。
发明内容
本实用新型的目的是针对现有技术存在的不足,提供一种可解决二端加工误差的用于加工汽门杆的夹具。
为实现上述实用新型目的,本实用新型采用的技术方案为一种用于加工汽门杆的夹具,包括后孔和与后孔相通的夹持孔,所述夹持孔的长径比为1:10。
所述夹持孔的长为50mm。
夹持孔的截面直径不变,夹具的总长不变,缩短了后孔的长度,加长了夹持孔的长度。
有益效果:本实用新型夹持孔长径比由原来的1:8改为1:10,有效径增长解决二端加工的误差,夹持孔增长直线度更高,产品的合格率大大增加。
附图说明
图1为本实用新型结构框图。
具体实施方式
下面结合附图和具体实施例,进一步阐明本实用新型,本实施例在以本实用新型技术方案为前提下进行实施,应理解这些实施例仅用于说明本实用新型而不用于限制本实用新型的范围。
如图1所示,一种用于加工汽门杆的夹具,包括后孔1和与后孔1相通的夹持孔2,夹持孔的长径比为1:10,夹持孔的长为50mm。
原夹具总长为143mm,原夹持孔的长味40mm,后孔长103mm,现在夹具总长不变,夹持孔截面直径不变,将其长径比由原来的1:8改为1:10,即夹持孔长度变为50mm,而后孔的长度缩短为93mm。夹持孔增长后,有效结局了二端加工误差问题,产品精度更高。
