Automatic screwturningmachine

Abstract

The invention discloses an automatic screw turningmachine which comprises a feeding mechanism and a screw turning mechanism. The feeding mechanism comprises a vibration disc, a material taking mechanical hand and a screw storing table, wherein the vibration disc is used for automatically sorting screws and conveying the screws in a directional mode, the material taking mechanical hand is used for attracting the screws and transferring the screws to the screw storing table, the screw storing table is used for storing the screws, the screw turning mechanism comprises at least one screw driver, a general electric screw driver and a first air cylinder, the screw drivers attract the screws through magnetic force, the general electric screw driver drives the screw drivers to rotate, the first air cylinder drives the general electric screw driver to move up and down, the first air cylinder drives the general electric screw driver to move downwards to be clamped with the screw drivers, and then the general electric screw driver drives the screw drivers to automatically turn the screws. According to the automatic screw turning machine, a magnetic type feeding automatic screw turning device is provided on the basis of traditional automatic nut turning, the screws can be fed at one time by the automatic screw turning machine, and the automatic screw turning machine drives the screw drivers to rotate so as to sequentially conduct screw turning. The automatic screw turning machine is rapid and reliable in feeding, stable and accurate in work, and capable of achieving rapid feeding of the screws of different specifications without replacing the screw drivers.

Description

technical field [0001] The invention relates to the field of automatic screw driving machinery, in particular to an automatic screw driving machine. Background technique [0002] At present, the automatic screw driving machines on the market generally realize orderly feeding and screw locking through two methods: array type and air blowing type. The efficiency is very low, and the structure is relatively complex, the working space is large, the reliability is not high, the maintenance is inconvenient, and the noise is loud. In addition, the track needs to be manually adjusted for the limited screws of different specifications; the air-blown automatic screw feeding machine is compared with the former The efficiency has been slightly improved, but there are still problems such as unstable feeding, low reliability, poor alarm maintenance, and easy screw superposition, especially for screws with a screw length-to-diameter ratio lower than 1:1. In addition, there is still no eff...
