Rivet perforation guide device of rotation wheel assembling machine

Abstract

The invention discloses a rivet perforation guide device of a rotation wheel assembling machine. The rivet perforation guide device is arranged at a perforation position of the rotation wheel assembling machine and comprises a propelling device and a guide device which are symmetrically arranged on two sides of the perforation position and cooperate for perforating a rivet, wherein the propelling device comprises a feeding device and an ejector pin device mounted behind the feeding device; a through hole used for horizontally placing the rivet is formed in the feeding device; the through hole directly faces the axle center of a trundle at the perforation position; the ejector pin device comprises an ejector pin used for ejecting the rivet in the through hole; the ejector pin is connected to an ejector pin cylinder which drives the ejector pin to move; the guide device comprises a guide pin capable of penetrating through the axle center of the trundle at the perforation position and then guiding the rivet to the axle center of the trundle; the guide pin is connected to a guide pin cylinder which drives the guide pin to move. Through the rivet perforation guide device of the rotation wheel assembling machine, the guide pin penetrates through the axle center of the trundle; when the rivet is pushed out by the ejector pin, one cap-free end of the rivet perforates along the guide pin and enters the axle center of the trundle; the perforation deviation of the rivet can be avoided; the perforation success rate of the rivet is increased; the automatic perforation is achieved; the perforation efficiency is improved.

Description

technical field [0001] The invention relates to a rivet piercing guide device of a runner assembly machine. Background technique [0002] The runner is the so-called movable caster, and its structure allows horizontal 360-degree rotation. Casters are a general term, including movable casters and fixed casters. The fixed casters have no rotating structure, and cannot be rotated horizontally but can only be rotated vertically. These two types of casters are generally used together. For example, the structure of the trolley is two fixed wheels on the front, and two movable wheels on the back near the push armrest. The runner means that the bracket installed on the caster wheel can rotate 360 ​​degrees horizontally under dynamic load or static load. When processing the runner, it is necessary to fix the caster wheel and the bracket together with rivets, not only to ensure that the caster can rotate vertically, but also to ensure that the bracket can rotate 360 ​​degrees horiz...

AI Technical Summary

Problems solved by technology

The existing processing technology is to manually insert the rivets into the bracket and the caster to connect the bracket and the caster, and then enter the next step of stamping and fixing. The manual mechanical operation has the disadvantages of low efficiency and high labor intensity.
