Abstract

The invention discloses a clamping arm for a robot. The clamping arm comprises a driving motor, a second sliding rod, a first connecting rod, a first clamping jaw, a second connecting rod and a secondclamping jaw. The driving motor is fixed in a base, the base, a middle section bracket, a front section bracket and a top seat jointly form a clamping arm body, the output end of the driving motor isfixedly provided with a reel, a pulling cord is wound around the reel, the extending-out end of the pulling cord is fixedly connected with a first sliding rod, the first sliding rod is slidably arranged in a pillar, the first sliding rod is sleeved with a spring, the first sliding rod is also fixedly connected with the second sliding rod, and the other end of the second sliding rod is provided with a clamping component. The clamping arm is novel in design and simple in structure; and through the set spring specification, when large objects are clamped, the objects cannot be damaged, and whenthe small objects are clamped, contact rubber is used for increasing the friction force between the clamping arm and the objects.

Description

technical field

[0001] The invention belongs to the field of clamping devices, and in particular relates to a clamping arm for a robot. Background technique

[0002] With the development of science and technology, more and more attention has been paid to robots. The main task of robots is to assist or replace human work, which can better serve human beings. However, the existing robot clamping arms often have complex structures and high costs. Problems such as poor clamping.

[0003] For example, the application number is 201821689627.2, and the Chinese patent (a robot clamping arm) with the announcement number CN208826625U discloses "a robot clamping arm, which is characterized in that: it includes a first clamping arm (1), a second clamping arm (2), the first jaw (3), the second jaw (4), the hinged seat (5), the hinged shaft (6), the reset cushion (7), the first stepper motor (8), the rope idler roller (9), traction rope (10), vertical support block (11), fastening nut (...
