Automatic assembling machine for tiny headless screws and nuts

Abstract

The invention relates to the technical field of automatic assembling machines, and discloses an automatic assembling machine for tiny headless screws and nuts. The machine comprises a rack, and the rack is provided with a screw feeding mechanism for screw feeding, a nut feeding mechanism, a screw grabbing mechanism, a screwing mechanism and a touch screen. The nut feeding mechanism is located at one side of the screw feeding mechanism and used for feeding nuts; the screw grabbing mechanism is located at one side of the nut feeding mechanism and used for grabbing screws; and the screwing mechanism is located at the rear side of the screw feeding mechanism and the nut feeding mechanism and used for assembling the screws and the nuts, and the touch screen is located at the front sides of the screw feeding mechanism and the nut feeding mechanism and used for controlling the assembling machine to start. According to the automatic assembling machine for the tiny headless screws and nuts, accurate butt joint of the screws and the nuts is achieved through an accurate screw grabbing and aligning mechanism, namely three sets of air cylinders are used for grabbing, aligning and limiting, and the situation that in the prior art, a claw clamp and spring integrated screwdriver bit cannot meet accurate alignment of the tiny screws and nuts, and consequently normal use cannot be achieved is avoided.

Description

technical field [0001] The invention relates to the technical field of automatic assembly machines, in particular to an automatic assembly machine for tiny headless screw nuts. Background technique [0002] Automatic assembly machine, also known as automatic assembly machine, refers to the combination of several parts of the product through tight fit, buckle, screw connection, bonding, riveting, welding, etc. to obtain predetermined dimensional accuracy and function. Finished (semi-finished) machinery and equipment. [0003] The general screw nuts in the prior art are relatively large in size, do not require high precision, and have a relatively simple structure. Therefore, most of the automatic assembly machines for tiny headless screw nuts are lacking on the market, and the minimum assembly size of the screw nut assembly also reaches M3 and above. , the automatic assembly of tiny headless screw nuts cannot be realized. In addition, the existing assembly machines will dama...

Problems solved by technology

[0003] The general screw nuts in the prior art are relatively large in size, do not require high precision, and have a relatively simple structure. Therefore, most of the automatic assembly machines for tiny headless screw nuts are lacking on the market, and the minimum assembly size of the screw nut assembly also reaches M3 and above. , the automatic assembly of micro-miniature headless screw nuts cannot be realized. In addition, the existing assembly machine will damage the electroplating layer of the product surface during use. Therefore, we propose an automatic assembly machine for micro-miniature headless screw nuts to solve the above problems
