Abstract

本实用新型公开了一种改进型的钎杆座,它包括座体、内套、外套、圆销和螺栓,其特征在于座体开有与钎杆配合的腔,内套设置于腔中部,外套设置在腔外侧,所述的座体在内套与外套之间开有圆销孔,圆销孔一端为直径小于圆销直径的沉孔,另一端为沉头螺栓孔,所述的圆销和螺栓通过沉孔和沉头螺栓孔与座体连接。本实用新型结构简单,从根本上杜绝了圆销脱落的问题。

Description

一种改进型的钎杆座
技术领域
    本实用新型属于工程机械设备,具体的是一种钎杆座。
背景技术
     钎杆是指向钎头传递动力,随同钎头进入钻孔的杆状或管状零件,因其具有良好的穿透力、破碎性,常被用于开山、修路、拆房等破碎面积较大的作业;现有的钎杆座一般通过开两头和圆销一样大小的两头沉孔和圆销、橡皮塞实现与内套、外套的配合,经过破碎锤的长期打击,由于冲击力及热胀冷缩等原因,橡皮塞容易滑落,导致内外套、扁销等脱落从而使整锤无法工作。
发明内容
    本实用新型所要解决的技术问题是提供一种改进型的钎杆座,从根本上杜绝圆销脱落的问题。
为解决上述技术问题,本实用新型提供一种改进型的钎杆座,它包括座体、内套、外套、圆销和螺栓,座体开有与钎杆配合的腔,内套设置于腔中部,外套设置在腔外侧,所述的座体在内套与外套之间开有圆销孔,圆销孔一端为直径小于圆销直径的沉孔,另一端为沉头螺栓孔,所述的圆销和螺栓通过沉孔和沉头螺栓孔与座体连接。
   本实用新型结构简单,从根本上杜绝了圆销脱落的问题。
附图说明
图1为本实用新型主视结构示意图。
图2为M-M剖视示意图。
具体实施方式
参见附图,一种改进型的钎杆座,它包括座体3、内套2、外套1、圆销5和螺栓4,座体开有与钎杆配合的腔,内套设置于腔中部,外套设置在腔外侧,所述的座体在内套与外套之间开有圆销孔,圆销孔一端为直径小于圆销直径的沉孔,另一端为沉头螺栓孔,所述的圆销和螺栓通过沉孔和沉头螺栓孔与座体连接。
   本实用新型结构简单,从根本上杜绝了圆销脱落的问题。
