Rotary mechanical arm with clamping and locking capacity for plastic shell machining

Abstract

The invention discloses a rotary mechanical arm with clamping and locking capacity for plastic shell machining, and relates to the technical field of rotary mechanical arms. The rotary mechanical armcomprises a rotating mechanism, a telescopic arm, a middle connecting arm, a rotary arm and a clamping mechanism, wherein the telescopic arm is connected to one side of the rotating mechanism, the middle connecting arm is connected to the lower portion of the telescopic arm, the rotary arm is installed on the lower portion of the middle connecting arm, the clamping mechanism is connected to the lower portion of the rotary arm, grabbing devices are hung on the four sides of a first base plate and the four sides of a second base plate correspondingly, and each grabbing device comprises a fixed hanging plate, a driving rotating shaft, a driver and an octopus plate. According to the rotary mechanical arm with the clamping and locking capacity for plastic shell machining, a plastic shell is firmly clamped, sucked and fixed through an octopus-like foot principle and an air pressure principle, in this way, the problem that the shell is damaged due to clamping can be effectively avoided, the locking capacity is high, the shell clamping step is omitted, and the clamping and releasing process of the shell is simple and is easy to control.

Description

technical field [0001] The invention relates to the technical field of rotary mechanical arms, in particular to a rotary mechanical arm with clamping and locking capabilities for processing plastic shells. Background technique [0002] The robotic arm refers to a complex system with high precision, multiple input and multiple output, high nonlinearity, and strong coupling. Because of its unique operational flexibility, it has been assembled in industry and has been widely used. The appearance of the robotic arm greatly saves manpower. Bring greater production benefits to the enterprise. The robotic arm can accept program programming control and has certain automation capabilities. Generally, more advanced automation equipment will be equipped with robotic arms and manipulators. [0003] In the production and processing of plastic shells, in addition to molding the shells, the formed shells also need to be polished, painted, engraved, punched, etc., so the plastic shells need...

AI Technical Summary

Problems solved by technology

[0004] When the existing mechanical arm clamps a large plastic shell, it often has the problem of not being able to clamp firmly because the outer wall of the plastic shell is not regular enough. The plastic shell is soft, and the traditional way of clamping is very easy to damage the shell. The shape and outer wall surface, and the traditional clamping mechanism requires multiple steps whether it is clamping or releasing, which is not convenient enough to use
