Embodiment Construction

[0020] The present invention completes the structural principle of functional action as:

[0021] see Figure 1 to Figure 8 , the vertical cylinder 1 drives the pressure sleeve 3 and the follower rod 5 (the inner diameter of the pressure sleeve 3 is larger than the diameter of the middle part of the follower rod 5 but smaller than the diameter of the upper end, and the follower rod 5 and the cylinder rod are elastically connected) to move downward, pressing The lower end of the sleeve 3 is fixed with a plurality of snap spring push rods 4 with an elastic ring, and the snap spring push rods 4 can be spread out or gathered, and the follower rod 5 contacts the cone 8 and pushes it to move downward to disengage from the horizontal baffle plate 12. The spring ejector rod 4 moves along with it during this process. After the internal diaphragm 11 of the cone cylinder 8 contacts the workpiece 15, the follower rod 5 is forced to shrink, and the spring ejector rod 4 slides along the out...

Abstract

The invention discloses a device for automatically installing a snap spring. The device is composed of a frame, a vertical cylinder, a pressing sleeve, a follower lever and a cone cylinder; the vertical cylinder is fixed at the top part of the frame, the pressing sleeve is coaxially fixed at a lower end of a hollow piston rod of the vertical cylinder, and a plurality of mandrils along the snap spring is arranged on the periphery of the lower end of the pressing sleeve; an upper end of the follower lever is thicker and positioned in the piston rod of the vertical cylinder and a lower end of the follower lever is fixed with a driving magnet, and a buffer spring is arranged in the piston rod of the vertical cylinder; the cone cylinder is positioned under the vertical cylinder, a diaphragm plate in the cone cylinder is fixed with a driven magnet which has a thick lower end and is positioned in a through hole on a horizontal baffle in the middle of the frame, a cone cylinder top block is arranged in a side wall of the through hole, and a compression spring is arranged between the cone cylinder top block and the horizontal baffle. The device for automatically installing the snap spring can well realize the automatic installation of a dustproof sleeve snap spring of ball pin products, the product quality is improved, the labor intensity of the worker is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a device for installing a locking clip spring of a dust cover of a ball pin product, which belongs to the technical field of automobiles. Background technique [0002] Ball pin products (such as attached figure 1 The dust cover of the product shown) is generally locked with a ring circlip. At present, the installation of the dust jacket circlip is generally done by hand or with the help of simple auxiliary tools. When installing, first use a special tool to stretch the circlip, and then rely on wrist force to wind the circlip on the dust jacket. The disadvantages of this installation method are complex operation, high labor intensity, low production efficiency, high requirements for the operator's operation skills, and because the end of the circlip is often tilted during the operation, it is easy to damage the dust cover, thereby Affect the tightness of the assembly. Therefore, how to efficiently install the dust jacket ret...
