The utility model provides a spring assembly frock includes base 1, is equipped with the erector 2 and the depression bar 3 of compression chamber 21, and erector 2 sets up in depression bar 3 top, and erector 2 sets up the compression chamber 21 of the form of the round platform of falling, and base 1's upper end carries out the shutoff in the bottom of compression chamber 21. When the miniature spring 01 and the spring fixing sleeve 02 are assembled, the miniature spring 01 is obliquely placed in a compression cavity 21 of the inverted round table, the bottom end of the miniature spring 01 is abutted to the upper surface of the base 1, the pressing rod 3 extends into the compression cavity 21, when the bottom end of the pressing rod 3 acts on the top end of the miniature spring 01, the miniature spring 01 is axially unstable, the bottom end of the miniature spring 01 rotates around the circumferential direction of the compression cavity 21, the pressing rod 3 continues to move downwards, the miniature spring 01 is finally compressed into a circular ring with the top end and the bottom end connected, the height of the circular ring is approximately equal to the outer diameter of the miniature spring 01, and finally the circular ring is placed in the spring fixing sleeve 02 to complete the assembly.
The spring assembling tool provided by the invention is described in more detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, in the embodiment of the present invention, the mounting device 2 and the base 1 are provided in a split type, the mounting device 2 is a cylindrical structure, the compression cavity 21 is provided inside the mounting device 2 and axially penetrates through the mounting device 2, and the compression cavity 21 is specifically in a shape of an inverted circular truncated cone with a diameter gradually decreasing from top to bottom; the upper end face of the base 1 is used as a compression end face, the mounting device 2 is placed above the base 1, the axis of the compression cavity 21 is approximately vertical to the upper end face of the base 1, the compression rod 3 extends into the compression cavity 21, and the compression molding is carried out on the micro spring 01 placed in the compression cavity 21 by moving the compression rod body along the axial direction of the compression cavity 21. By means of the characteristic that the miniature spring 01 is axially unstable under pressure, the miniature spring 01 is extruded into a circular ring by matching with the limit of the inverted circular truncated cone-shaped compression cavity 21. Finally, the mounting device 2 is directly pushed into the spring fixing sleeve 02 by the pressure rod 3.
In order to prevent the mounter 2 from shaking relative to the base 1 when the micro spring 01 is compression molded, the mounter 2 and the base 1 are specifically positioned by adopting detachable assembly. Specifically, a positioning boss 11 may be provided on the upper end surface of the base 1, and a positioning hole 22 may be provided at the bottom (the end of the compression chamber 21 having a smaller diameter) of the mounting unit 2 to be engaged with the positioning boss 11. The positioning hole 22 is usually coaxial with the compression chamber 21 and is preferably provided as a circular positioning hole 22, and correspondingly, the positioning boss 11 is a circular boss. The diameter of the positioning hole 22 or the diameter of the positioning boss 11 is larger than the diameter of the bottommost part of the compression cavity 21 and equal to the outer diameter of the spring fixing sleeve 02, and after the mounter 2 and the base 1 are mounted and embedded in place through the positioning hole 22 and the positioning boss 11, the upper end face of the positioning boss 11 serves as a compression end face.
In the above embodiment, the assembly process is divided into two steps, the first step: firstly, mounting a mounting device 2 on a positioning boss 11 of a base 1, then putting a micro spring 01 into an upper port of a compression cavity 21, and finally compressing the micro spring 01 in the mounting device 2 along the axial direction of the inner wall of the micro spring by a pressure rod 3, so that the micro spring 01 is axially unstable and then axially and spirally moves downwards along the inner wall of the compression cavity 21 until being completely attached to the positioning boss 11 to form a circular ring; the second step is that: placing the spring fixing sleeve 02 on the base 1, and placing the installer 2 provided with the ring in the first step on the spring fixing sleeve 02 through the positioning hole 22 to ensure that the spring fixing sleeve 02 is placed in place; the compression bar 3 is used for directly pushing the circular ring spring fixing sleeve 02 formed by the micro spring 01 in the mounting device 2 along the axial direction, and thus, the assembling process of the micro spring 01 and the spring fixing sleeve 02 is completed.
The inverted circular truncated cone-shaped arrangement of the compression cavity 21 adopts the funnel principle, so that the miniature spring 01 can be conveniently placed in the compression cavity; the installer 2 scientifically utilizes the axial instability-prone characteristic of the cylindrical spring with a larger major diameter, and skillfully performs the micro spring 01 into a circular ring by means of the compression rod 3 and the compression cavity 21, so that convenience is provided for subsequent assembly; the miniature spring 01 (pressed into a circular ring) in the mounting device 2 is directly pushed into the spring fixing sleeve 02 by the pressure lever 3, so that the assembly efficiency is greatly improved. The positioning holes 22 are arranged to not only position the mounter 2 by matching with the positioning bosses 11, but also meet the requirement that the spring fixing sleeve 02 is mounted at the bottom of the mounter 2, so that the miniature spring 01 compressed into a circular ring can be conveniently pushed into the spring fixing sleeve 02, as shown in fig. 4 and 5.
Optionally, the upper end surface of the base 1 may be further provided with a circular groove, the center of the circular groove is provided with the positioning boss 11, and the bottom of the mounting device 2 is provided with the positioning hole 22; further positioning is achieved by means of the circular recess in cooperation with the mounting means 2.
In the above embodiment, the pressing rod 3 specifically includes a pressing rod body and a pressing rod handle, both of which are cylindrical and coaxially disposed. Wherein, the diameter of the compression bar body is equal to the diameter of the compression cavity 21 away from the preset height of the bottom surface of the compression cavity 21, for example, the diameter of the bottom of the compression cavity 21 is d1Top diameter of d3，d3Greater than d1D is the diameter at a distance h from the bottom of the compression chamber 212，d1＜d2＜d3(ii) a h is slightly smaller than the outer diameter of the micro spring 01, and the diameter of the pressure lever body is d2The compression bar body is prevented from flattening the micro spring 01 when the micro spring 01 is compressed into a circular ring. When the circular ring is pushed into the spring fixing sleeve 02, the diameter of the circular ring is smaller than d1The push rod pushes the circular ring.
