Automatic screw locking machine and screw guiding mechanism

Abstract

The invention discloses a screw guiding structure and an automatic screw locking machine. The screw guiding structure comprises a conical base and four plane jaw pieces. The four plane jaw pieces are fixedly connected with the four side walls of the conical base respectively. A first guiding channel is defined by the parts, extending out of a first opening, of the four plane jaw pieces, and the first guiding channel is provided with a first guiding hole communicated with the outside. A first screw slides to the first guiding channel from the first opening and slides in the first guiding channel until the inner walls of the first guiding channel clamp the brim of the first screw and a screw rod of the first screw protrudes out of the screw guiding structure in the first direction, and then the first screw is locked. The projection area of the first guiding hole on a first plane is smaller than the projection area of the first opening on the first plane. Thus, the requirement for the locking space is lowered, and the structure is simple.

Description

technical field [0001] The invention describes an automatic screw locking machine, especially a screw guide structure of the automatic screw locking machine. Background technique [0002] At present, in many manufacturing industries such as electronics, electrical machinery, mechanical hardware, toys and furniture products, the combination and fixation of workpieces are often completed by locking and locking, so screws play an indispensable role in daily life and industry. role, and widely used in various fields, the market opportunities are huge. [0003] The traditional way of locking screws for workpieces is often to use purely manual operation for screw locking. This technology is not only time-consuming and laborious, but also has extremely low work efficiency. [0004] In order to improve the speed and quality of locking screws, using an automatic screw locking machine is a solution. Compared with the traditional screw locking method, the automatic screw locking mach...

Problems solved by technology

However, the mouth-shaped design of the existing automatic locking screw machine takes a large locking space, especially when the screw is to be locked near the screw hole with a boss (protruding from the outer edge of the screw hole), and the screw hole When the distance between the outer edge and the boss is small (for example, our current display frame is generally 2mm-5mm from the outer edge of the screw hole), the mouth shape design of the automatic locking screw machine will interfere with the boss (the existing automatic lock The minimum distance between the boss and the edge of the screw hole required by the mouth shape design of the screw machine, that is, the clearance space, is 10mm), which affects the locking of the screw, resulting in low reliability

Moreover, the commonly used automatic locking screw machine has a complex structure, requires high machining accuracy, complex process, and high cost
