Description

凹坑拉出器 技术领域
本实用新型涉及钣金机械领域，具体来说涉及一种凹坑拉出器。
背景技术
在汽车钣金中为了将凹陷的汽车板材复原，常常需要使用凹坑拉出器将板材拉平。而现有的凹坑拉出器设计简单，使用时常常需要先用电钻将汽车板材钻孔，再将凹坑拉出器插入板材凹坑中将板材表面褶皱凹陷处拉平，操作起来十分麻烦，且不够灵活。
实用新型内容
本实用新型主要解决的技术问题是提供一种凹坑拉出器，可以无需使用电钻，直接在汽车板材凹陷处开口，并且能够直接拉平板材，完成钣金工作，提高了汽车钣金的工作效率。
为实现上述目的，本实用新型提供以下的技术方案：一种凹坑拉出器，其特征在于：所述凹坑拉出器包括圆柱形的拉杆，拉杆一端设有环形的握环，拉杆的另一端设有分叉杆，分叉杆两端分别设有自攻钻头和拉钩，自攻钻头呈圆锥形，且自攻钻头表面攻有凸螺纹。
作为本技术方案的进一步优化，所述拉杆、自攻钻头、拉钩、握环、分叉杆均由合金工具钢制造，分叉杆、拉杆、自攻钻头、拉钩、握环、分叉杆均为整体结构。
作为本技术方案的进一步优化，所述分叉杆为圆角形。
采用以上技术方案的有益效果是：该凹坑拉出器的拉杆一端设有环形的握环，拉杆的另一端设有分叉杆，分叉杆两端分别设有自攻钻头和拉钩。当需要将凹陷的汽车板材复原时，钣金工人可手握握环并旋转，将自攻钻头钻入汽车板材凹陷处，直接将凹陷的板材拉平，而当汽车板材凹陷较深时，可退出自攻钻头，将拉钩穿入钻孔内，手 握握环将汽车板材凹陷处拉平。该凹坑拉出器圆角的分叉杆有效保护了操作人员的人身安全，而且使用简单方便，提高了汽车钣金的工作效率。
附图说明
下面结合附图对本实用新型的具体实施方式作进一步详细的描述。
图1是本实用新型第一种结构示意图。
图2是本实用新型第二种结构示意图
其中，1—拉杆、2—自攻钻头、3—拉钩、4—握环，5.分叉杆。
具体实施方式
下面结合附图详细说明本实用新型一种凹坑拉出器的优选实施方式。
图1出示本实用新型一种实施方式：该凹坑拉出器包括圆柱形的拉杆1，拉杆1一端设有环形的握环4，拉杆1的另一端设有两个平行的分叉，两分叉上分别设有自攻钻头2和拉钩3，自攻钻头2呈圆锥形，且自攻钻头2表面攻有凸螺纹。
如图1所示，拉杆1、自攻钻头2、拉钩3、握环4均由合金工具钢制造，坚固耐用，使用寿命长，拉杆1、自攻钻头2、拉钩3、握环4均为整体结构。
图2出示本实用新型的另一种实施方式：该凹坑拉出器包括圆柱形的拉杆1，拉杆1一端设有环形的握环4，拉杆1的另一端设有分叉杆5，分叉杆5两端分别设有自攻钻头2和拉钩3，自攻钻头2呈圆锥形，且自攻钻头2表面攻有凸螺纹。
如图1所示，拉杆1、自攻钻头2、拉钩3、握环4、分叉杆5均由合金工具钢制造，坚固耐用，使用寿命长，拉杆1、自攻钻头2、拉钩3、握环4、分叉杆5均为整体结构。
当需要将凹陷的汽车板材复原时，钣金工人可手握握环4并旋转，将自攻钻头2钻入汽车板材凹陷处，直接将凹陷的板材拉平，而当汽车板材凹陷较深时，可旋转着退出自攻钻头2，将拉钩3穿入钻孔内，手握握环4将汽车板材凹陷处拉平。该凹坑拉出 器圆角的分叉杆有效保护了操作人员的人身安全，而且使用简单方便，提高了汽车钣金的工作效率。
以上的仅是本实用新型的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。
