Handheld automatic screw machine

Abstract

The invention discloses a handheld automatic screw machine. The handheld automatic screw machine comprises an electric screwdriver, a driving device and a clamping nozzle structure, the clamping nozzle structure comprises a clamping nozzle structure body provided with a material storage cavity and two clamping nozzle blocks rotationally arranged on the clamping nozzle structure body, the top end of the clamping nozzle structure body is movably sleeved with a transmission sleeve fixedly connected with a driving rod, an elastic piece is arranged between the transmission sleeve and the clamping nozzle structure body, a screw in the material storage cavity is pushed and positioned at a clamping opening between the two clamping nozzle blocks through a screwdriver head of the electric screwdriver, and by means of the design, the screwdriver head is kept in a vertical state when abutting against the screw, and can be quickly and accurately aligned with a hole position of a mounting position, and then the screw is inserted into the hole for locking through the screwdriver head. According to the automatic screw machine adopting the scheme, the perpendicularity when the screwdriver head and the screw are installed and locked can be guaranteed, the situation that the screw deflects and shakes is avoided, the use stability is good, the screw can be rapidly installed, installation is accurate and reliable, and the use performance and the market competitiveness of products are improved.

Description

Technical field [0001] The present invention relates to the field of screw machine, and more particularly to a hand-held automatic screw machine. Background technique [0002] The hand-held screw machine is also called the automatic lock screw machine, which is used to replace the manager's finishing, put, tighten the automation device, which can be used for automatic assembly of the pillar and small parts. The application prospect is very broad. This kind of hand-held screw machine can be liberated, only one hand is aligned with the screw hole lock screw, just lift the screwdriver to match the next screw hole lock screw after the lock is locked. However, the machine will automatically transfer a screw to a batch of nozzles in an instant that lifts the screwdriver, waiting to lock a screw, so repeated. [0003] For example, China Patent Document CN210818343U discloses a hand-held lock screw machine, including electric batch, chuck assembly, and suction attachment, wherein one end...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the problem that the screws absorbed by the bit cannot maintain verticality during the screwing process of the screw locking machine in the prior art, so that the screws are deflected and shaken, and the use stability is poor, which affects the product. In order to provide a hand-held automatic screw machine that maintains the verticality between the bit and the screw, prevents the screw from deflecting and shaking, has good stability in use, and improves the performance of the product.
