Steel ball detection installation device for cage

Abstract

The invention discloses a device for detecting and mounting steel balls for a retainer. The device comprises a controller and parts arranged on a machine body; a driving air cylinder, a sliding rail, a sliding block, a bracket, ejector rods, changeover rods, compressed springs, displacement sensors and an adjusting block are arranged at the upper part of the machine body; a moving air cylinder and a limiting block are arranged in the middle of the machine body; a rotary table, a positioning tooling, a material distribution block, a material dropping hopper, a material sorting plate, a switchover air cylinder and a material feeding block are arranged at the lower part of the machine body; the positioning tooling is mounted on the rotary table, rotates relative to work stations and comprises guide holes A, guide holes B and positioning grooves; the material sorting plate comprises ball separating holes, waist-shaped holes and a detection fundamental plane; the material distribution block comprises qualification channels, recovery channels and a slideway groove; the material feeding block comprises ejector rod guide holes and ball inlet hole channels. When the detection result shows that steel balls are unqualified in diameter, an operation mechanism automatically discharges the unqualified steel balls to a waste material hopper; when the detection result shows that steel balls are qualified in the quantity and diameter, the operation mechanism conveys the qualified steel balls to press mounting hole channels, and then the qualified steel balls are pressed into spherical pits in the retainer through corresponding pressing rods.

Description

technical field [0001] The technology relates to the field of automobile manufacturing, in particular to a steel ball detection and installation mechanism device for a cage on a slide rail of an automobile seat. Background technique [0002] Based on the current rapid development of the automobile industry, as a key component of the seat, the car seat slide rail plays the role of adjusting, fixing and locking the seat. The size of the sliding force of the seat slide rail, whether the sliding is smooth and stable, whether the structure is reasonable and safe, whether it can improve production efficiency and reduce manufacturing costs are one of the focuses of engineers and technicians in the field of automobile manufacturing. [0003] Car seat slides consist of an inner rail and an outer rail. There are two spherical slideways on the longitudinal sides of the inner rail and two spherical slideways on the longitudinal sides of the outer rail, corresponding to each other. Corr...

AI Technical Summary

Problems solved by technology

There are two spherical slideways on the longitudinal sides of the inner rail and two spherical slideways on the longitudinal sides of the outer rail, corresponding to each other. Corresponding steel balls are placed between each slideway to make the inner rail and the outer rail retract. Longitudinal sliding and positioning and locking functions of outreach; the following methods are generally used for placing steel balls: 1. Place several corresponding steel balls symmetrically on both ends of each slide of the corresponding length slide rail, and place a corresponding length of steel ball in the middle. The advantage of this method is that the length of the gap spacer can be adjusted according to the requirements of the seat specification. The disadvantage is that it is inconvenient to place the materials scattered during the assembly of the slide rail. Regardless of manual assembly or mechanical tooling subsidy assembly, each It is labor-intensive and time-consuming to install the corresponding steel balls on the slide rails, and the steel balls will be mis-installed and mis-installed. After installation, the steel balls are easy to fall off, resulting in unstable sliding performance of the slide rails; For the corresponding plastic cage, a number of hollow spherical sockets are symmetrically arranged at both ends of the cage, and corresponding steel balls are placed in the spherical sockets. The advantage of this method is that the corresponding steel balls placed in the spherical sockets are stable and not easy to fall off, and the corresponding length of the cage is appropriate. The gap spacer is omitted, and the installation is more convenient. The disadvantage is that it can only be used on the slide rails of limited specifications, and each slide rail needs to be placed with a whole cage, which cannot adapt to the length change of the slide rail specifications. How to accurately place the corresponding steel balls If it is installed on a new type of cage, a set of detection and installation mechanism devices are required to accurately detect the diameter and quantity of steel balls, control the separation and recovery of unqualified steel balls, and place qualified steel balls in the spherical socket on the cage.
