Parallel clamping device and method for robot end

Abstract

The invention discloses a parallel clamping device and method for a robot end. The parallel clamping device for the robot end comprises a driving air cylinder, a parallel clamping mechanism and two end clamping mechanisms, wherein the two end clamping mechanisms are arranged on the two sides of the parallel clamping mechanism respectively, and the two ends of the driving air cylinder are fixedly connected with the two end clamping mechanisms respectively. The parallel clamping method for the robot end comprises the steps that the two end clamping mechanisms are symmetrically arranged on the two sides of the parallel clamping mechanism respectively, and are connected with the parallel clamping mechanism through adjusting rods, the two ends of each adjusting rod are hinged to the parallel clamping mechanism and the corresponding end clamping mechanism, a rotating base is used in cooperation so that when the driving air cylinder works, the two end clamping mechanisms can be driven to synchronously run, and clamping or loosening of workpieces can be achieved. According to the parallel clamping device for the robot end, the mode that one driving air cylinder is used for driving the two end clamping mechanisms is adopted, the rotating base and the adjusting rods are used in cooperation, synchronous operation of the two end clamping mechanisms is achieved, clamping is stable, alignment performance and synchronism are high, the accuracy rate of clamping is high, and production efficiency and the degree of automation of a production line can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of industrial robots for automatic handling, in particular to a parallel clamping device and method for the end of a robot. Background technique [0002] In robot automatic handling technology, the clamping method of two-finger parallel motion is widely used, and this clamping method can be used for plate parts, disk parts, shaft parts, box parts, etc. [0003] At present, there are two main two-finger gripping methods used at home and abroad: one is to directly use pneumatic parallel grippers, and the other is to use dual cylinders to control parallel grippers. However, in practical applications, the way of pneumatic parallel grippers is to use the pneumatic system of the production line to directly control the movement of parallel grippers. This method has complex equipment structure, small clamping force, inconvenient maintenance, and high equipment cost; The way the cylinder controls the grippers is to ...

However, in practical applications, the way of pneumatic parallel grippers is to use the pneumatic system of the production line to directly control the movement of parallel grippers. This method has complex equipment structure, small clamping force, inconvenient maintenance, and high equipment cost; The way the cylinder controls the grippers is to set up two sets of cylinder mechanisms to control the grippers that make up the parallel grippers separately. However, in actual production, the parallel grippers have poor synchronization and ri
