Description

一种具有快速装夹功能的定位销装置A positioning pin device with quick clamping function

技术领域technical field

本实用新型涉及一种具有快速装夹功能的定位销装置,用于产品装配过程零部件的定位,属于装配制造技术领域。The utility model relates to a positioning pin device with a fast clamping function, which is used for the positioning of components in the product assembly process and belongs to the technical field of assembly and manufacturing.

背景技术Background technique

用于孔定位的定位销结构通常结构只是一个直径和定位孔有配合关系的简单圆柱体结构,这种构造导致定位销插入定位孔进行装配时,无法立即实现被定位件的夹紧固定,通常还需要其他辅助工具(如弓形夹等)配合使用,实现夹紧功能。The structure of the positioning pin used for hole positioning is usually just a simple cylindrical structure with a diameter and a matching relationship with the positioning hole. This structure makes it impossible to clamp and fix the positioned part immediately when the positioning pin is inserted into the positioning hole for assembly. It also needs other auxiliary tools (such as bow clips, etc.) to be used in conjunction to realize the clamping function.

因此,目前的定位销只能实现孔定位,而无法同时实现夹紧,装配效率低;采用辅助工具时还需考虑夹紧空间等问题,给操作过程带来繁琐和不便。此外,国内外在产品装配时,也采用了其他定位件如手动或气动拉码等,虽然可以实现被定位件的快速定位,但拉码直径和定位孔直径相差较大,定位精度差,而且拉码结构本身较为复杂,制造成本高。Therefore, the current locating pins can only achieve hole positioning, but cannot achieve clamping at the same time, and the assembly efficiency is low; when using auxiliary tools, issues such as clamping space need to be considered, which brings cumbersome and inconvenient operations. In addition, other positioning parts such as manual or pneumatic pull codes are also used in product assembly at home and abroad. Although the rapid positioning of the positioned parts can be achieved, the diameter of the pull code and the diameter of the positioning hole are quite different, and the positioning accuracy is poor. The pull code structure itself is relatively complicated, and the manufacturing cost is high.
