Barrel bottom flange automatic screw fixing equipment

Abstract

The invention discloses barrel bottom flange automatic screw fixing equipment which comprises an automatic tightening unit, a rotary positioning tool and an automatic screw feeding unit. The automaticscrew feeding unit is composed of a stock bin, a screw screening mechanism, a screw separation mechanism and a screw blowing mechanism. The screw screening mechanism pushes screws in the stock bin toa screw temporary storage track through lifting, multiple sets of air cylinders of the screw separation mechanism are combined with sensor signals to distribute the screws to screw feeding pipelines,the screw blowing mechanism senses screw side blowing to blow the screws to a spray head, the automatic tightening unit is composed of a servo system, a lifting mechanism and tightening mechanism, apressing mechanism drives the tightening mechanism to descend to the preset height, a screwdriver drivers the screws to descend to a given position, and the servo system drives the screwdriver to tighten the screws. The automation degree is high, automatic screw conveying and tightening can be achieved, an air cylinder pushes a screw feeding mechanism to feed screws, operation is economic and simple, the accuracy rate is high, torque is controllable, and compatibility is high.

Description

technical field [0001] The invention relates to automatic equipment for screwing the bottom flange of a pulsator washing machine, in particular to an automatic screwing device for the bottom flange of a drum. Background technique [0002] The bottom of the barrel of the pulsator washing machine is equipped with a disc pulsator with protruding ribs. Driven by the pulsator, the water flow in the bucket forms a vortex that is sometimes right-handed and sometimes left-handed, driving the fabric to rotate and tumble, so that the dirt on the clothes can be removed. The pulsator washing machine is a kind of washing machine. The pulsator is driven by the motor to rotate, and the clothes are constantly tumbled up and down with the water. There are several kinds of washing clothes, such as single bucket, sleeve bucket and double bucket. Its structure is relatively simple, easy to maintain, and has a high cleaning rate, but it has a high wear rate on clothes and uses a lot of water. ...

AI Technical Summary

Problems solved by technology

However, the existing pulsator washing machine has a low degree of automation for screwing the bottom flange of the drum, and the automatic delivery and tightening of the screws cannot be realized, and the accuracy is low, and the torque is uncontrollable. In order to solve the above-mentioned problems, the present invention designs a drum Bottom flange automatic screwing equipment
