Description

Technical Field

[0001] The utility model belongs to the technical field of terminal machines, and particularly relates to a link-type rapid terminal machine. Background Art

[0002] A terminal is a fitting product used to achieve electrical connection. With the increasing level of industrial automation and the increasingly strict and precise requirements for industrial control, the usage of terminals has gradually increased. With the development of the electronics industry, terminals have been widely used in various fields, including signal terminals, power terminals, connection terminals, etc., and are the connection ends in a circuit. A terminal machine refers to a machine used for wire processing. It presses a terminal piece onto the conductive end of a wire, enabling electrical connection between the terminal piece and the conductive end of the wire. After pressing, the connection between the terminal and the conductive end of the wire can be achieved without welding, which is convenient for use.

[0003] For example: The Chinese utility model patent with the publication number CN210576965U discloses a servo terminal machine. Paragraph

[0065] of its specification records that "as Figures 4 - 5 shown, the up-and-down driving assembly 42 includes a servo motor 421, an eccentric shaft 422, a small slider 423, and a large slider 424; the output shaft of the servo motor 421 is connected to one end of the eccentric shaft 422 through a coupling, one end of the eccentric shaft 422 is connected to the small slider 423, a horizontally oriented groove 425 is provided on one side surface of the large slider 424, the small slider 424 extends into the groove 425 and slides along the inner wall of the groove 425, and the lower end of the large slider 424 is connected to the up-and-down moving block 30041. Specifically, when the servo motor 421 drives the eccentric shaft 422 to rotate, when the eccentric shaft 422 drives the small slider 423 to slide left and right along the groove 425, it drives the large slider 424 to move up and down."

[0004] As can be seen from the above, during operation, the servo motor 421 drives the small slider 423 to reciprocally slide along the inner wall of the groove 425 through the eccentric shaft 422, thereby driving the large slider 424 to move up and down, and further driving the upper forming member 45 to move up and down, so that the upper forming member 45 abuts against or moves away from the lower forming member 46, and when the upper forming member 45 and the lower forming member 46 cooperate and abut, the terminal piece is pressed onto the conductive end of the wire. However, the above-mentioned servo terminal machine has the following technical defects during actual use: During the process of the small slider 423 reciprocally sliding along the inner wall of the groove 425, the friction between the small slider 423 and the groove wall of the groove 425 of the large slider 424 is relatively large, which is prone to wear, affecting the service life, and the movement is not smooth enough, and the processing efficiency needs to be improved.
