Roll-over type mechanical arm

Abstract

The present invention relates to an overturn type manipulator which comprises a driving arm, a driven arm, an overturn control cam, a clamp control cam, a clamp spring, a left jaw and a right jaw. The driving arm is fixed at a turnplate by a driving arm shaft. The driven arm is fixed at the turnplate by a driven arm shaft. One end of the driving arm is equipped with the left jaw by a left jaw rotating shaft. The other end of the driving arm is connected with one end of the driven arm by a gear pair. The other end of the driven arm is equipped with the right jaw by a right jaw rotating shaft. The left jaw rotating shaft is connected with an overturn transmission mechanism which is used for controlling the left jaw rotating shaft to rotate. The overturn transmission mechanism is contacted and matched with the overturn control cam. The present invention provides an overturn type manipulator which has simple and compact structure and low manufacturing cost, occupies small space and works stably and reliably.

Description

technical field [0001] The invention mainly relates to the field of manipulators widely used on large-capacity bottle cleaning and filling equipment in the medicine and food industries, in particular to a flip-type manipulator. Background technique [0002] At present, the reversible manipulator is completed in motion from grabbing materials to reversing materials to other processes (such as cleaning...) to reversing materials and unloading. Generally, the cam is fixed, and the turntable is equipped with the main arm, the driven arm and its accessories. Rotating together, this kind of manipulator includes a master arm and a slave arm, and there is a gear pair between them. The master arm is controlled by the cam through the gear pair to make the slave arm linked. , the spring between the master and slave arms pulls the master and slave arms back (the gear pair reverses), the manipulator closes, grabs the grasped object and turns it over together, and runs smoothly for a cert...

Problems solved by technology

Its shortcoming is that the flip cam not only needs to control the vertical movement of the pull rod but also controls the horizontal movement of the pull rod. It is generally made of a round tube with complex curves and a huge shape, making it difficult to manufacture; the connecting plate on the turntable The distance between the center of rotation and the center of the gripper is large, resulting in a large volume of the main machine using this flip-type manipulator as a component, a large footprint, and high cost; dry friction between the cam and the pull rod rubber sleeve produces fine wear particles, Affect the accuracy of control and pollute the working environment
