一种组合辙叉用开口弹簧销的安装装置

Abstract

本实用新型涉及一种组合辙叉用开口弹簧销的安装装置，属于开口弹簧销安装技术领域。包括固定座，所述固定座的内部为空心管状结构，夹紧件设于所述固定座的顶端开口，并呈轴向移动设置，旋转件设于所述固定座的内部，带动夹紧件在固定座内呈轴向移动，对开口弹簧销完成变径，防转件固定设于所述固定座的一侧，并延伸至固定座的内部与夹紧件限位抵触，限制夹紧件在轴向移动过程中进行转动。通过配合电动扭矩扳手使用，不仅操作上更加简单、省力，而且还能够预先将开口弹簧销的外径变小，可轻易将开口弹簧销装入螺栓孔内，开口弹簧销装入过程中外壁不与螺栓孔壁发生摩擦，进而不会产生刮痕，保证了开口弹簧销的性能。

Claims

1. An installation device for open spring pins for a combination frog, characterized in that include: The fixing seat (10) has a hollow tubular structure inside; A clamping member (20) is provided at the top opening of the fixed base (10) and is axially movable; The rotating component (30) is located inside the fixed seat (10) and drives the clamping component (20) to move axially within the fixed seat (10), thereby changing the diameter of the open spring pin. The anti-rotation component (40) is fixedly disposed on one side of the fixed seat (10) and extends into the interior of the fixed seat (10) to limit and abut against the clamping component (20), thereby restricting the clamping component (20) from rotating during axial movement.

2. A mounting device for a split spring pin of a combination frog according to claim 1, characterized in that The clamping member (20) includes a straight tube section (201) and a variable diameter section (202), with the variable diameter section (202) integrally formed at the top end of the straight tube section (201); The fixed base (10) has a sliding cavity (102) inside that slides in contact with the straight tube (201); The top of the fixed base (10) is provided with an extrusion groove (103) that is used in conjunction with the variable diameter part (202), and the extrusion groove (103) is connected to the sliding cavity (102).

3. A mounting device for a split spring pin of a combination frog according to claim 2, characterized in that The variable diameter section (202) is composed of multiple extrusion plates arranged in an annular shape at equal intervals, and the inner surface of the multiple extrusion plates is a cylindrical inner circle, and the outer surface of the multiple extrusion plates is a conical outer circle.

4. A mounting device for a split spring pin of a combination frog according to claim 3, characterized in that The rotating component (30) includes a rotating head (301) and a threaded rod (302). The bottom end of the threaded rod (302) is integrally formed on the top of the rotating head (301), and the bottom end of the straight tube (201) is provided with an internal threaded hole (2012) that is threadedly connected to the threaded rod (302). The bottom end of the fixed base (10) is provided with a bottom groove (101) that is adapted to and engages with the rotating head (301), and the bottom groove (101) and the sliding cavity (102) are connected through a through hole (104).

5. A mounting device for a split spring pin of a combination frog according to claim 4, characterized in that The bottom of the rotating head (301) is provided with a square groove (3011).

6. A mounting device for a drop spring pin of a combination frog according to claim 2 or 5, characterized in that The anti-rotation component (40) includes an integrally formed locking block (401) and a stop block (402); The outer wall of one side of the fixed base (10) is provided with a slot (105) for connecting with the card block (401); The inner wall of one side of the fixed base (10) is provided with a card hole (107) that is adapted to be inserted into the abutment block (402), and the card hole (107) is connected to the card groove (105). The outer wall of one side of the straight tube section (201) is provided with a vertical groove (2011) that engages with the limiting and abutting block (402).

7. A mounting device for a split spring pin of a combination frog according to claim 5, characterized in that It also includes a cap (50) that is fixedly connected to the bottom end of the fixing seat (10) by bolts (60); The top of the pressure cap (50) has a hexagonal hole (501).
