Intelligent powder spraying device for machining automobile hub

Abstract

The invention relates to an intelligent powder spraying device for machining an automobile hub. The intelligent powder spraying device comprises a powder box, a controller, a fixing mechanism, a firstnozzle, a bottom surface spraying mechanism, a branch pipe and a top surface spraying mechanism. The bottom surface spraying mechanism comprises a first motor, a driving gear, a driven gear, a vertical pipe, a transverse pipe, a second nozzle and a supporting assembly. The fixing mechanism comprises a plurality of fixing assemblies. Each fixing assembly comprises a fixing rod, a fixing plate, a driving unit, a movable ring and a plurality of fixing units. The top surface spraying mechanism comprises a top plate, a lifting assembly, a third nozzle and a hose. According to the intelligent powder spraying device for machining the automobile hub, fixing of the hub is achieved through the fixing mechanism, and the hub is conveniently driven to rotate and be sprayed, not only that, the hub is driven to rotate by utilizing the bottom surface spraying mechanism so that powder sprayed out by the first nozzle, the second nozzle and the third nozzle can evenly adhere to the two surfaces of the hub, and the hub powder spraying quality is improved accordingly.

Description

technical field [0001] The invention relates to the field of production equipment for automobile spare parts, in particular to an intelligent powder spraying device for processing automobile wheel hubs. Background technique [0002] The wheel hub is also called the rim, the wheel, and the tire bell. It is a barrel-shaped, center-mounted metal part that supports the tire on the inner profile of the tire. There are many types of hubs according to diameter, width, molding method and material. The manufacturing process of the wheel hub is very complicated. According to the production process, it mainly includes raw material dissolution, mold preparation, casting, casting molding, X-ray inspection, high temperature heat treatment, machining, runout inspection, dynamic balance inspection, water leak test, sand blasting, and powder spraying. , Finished product off-line, radius load test, bending force test, impact test, finished product packaging and other production and processin...

AI Technical Summary

Problems solved by technology

However, the structure of the existing spraying device is simple, the direction of the nozzle is fixed, and only one side of the wheel hub is sprayed. In order to ensure that both sides of the wheel hub can adhere to the powder, it is necessary to switch the direction for secondary spraying, resulting in a decrease in spraying efficiency. Not only that, Before spraying, the bracket is usually inserted into the bolt hole of the hub for fixing, causing the bracket to block the spread of powder, resulting in uneven powder adsorption on the surface of the hub, thereby reducing the practicability of the existing powder spraying device
