Mechanical hand with balance cylinder

Abstract

The invention relates to the technical field of mechanical hands, in particular to a mechanical hand with a balance cylinder. The mechanical hand comprises a fixing rack and a first-stage movable arm arranged on the fixing rack in a penetrating manner; the first-stage movable arm is connected to a Z-axis transmission mechanism for driving the first-stage movable arm to move up and down; the fixing rack is provided with the balance cylinder; the end part of a piston rod of the balance cylinder penetrates the fixing rack to be fixedly connected with the first-stage movable arm. When being applied to an injection molding machine, the mechanical hand with the balance cylinder provided by the invention is suitable for driving and controlling first-stage movable arms in different sizes and quality to move up and down; as the balance cylinder is arranged, on one hand, the loading of the Z-axis transmission mechanism is reduced, so that the energy consumption of the Z-axis transmission mechanism is reduced; on the other hand, the Z-axis transmission mechanism can relatively flexibly and freely drive and control the first-stage movable arm to move up and down.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulator with a balance cylinder. Background technique [0002] With the development of computer and automation technology, manipulators are widely used in industrial production to replace manual operations. In the existing injection molding field, the role of the injection molding machine manipulator is to take out the injection molded product from the mold, saving manpower and material resources, thereby increasing production capacity and reducing costs; and with the development of manipulator technology, the industry’s requirements for manipulators are also increasing. Higher and higher, the action of the manipulator needs to achieve high precision, and it must be stable and reliable during operation. Among them, the weight of the first section of the mobile arm of the injection molding machine manipulator is often relatively large. The traditional injection mol...

Problems solved by technology

Among them, the weight of the first section of the mobile arm of the injection molding machine manipulator is often relatively large. The traditional injection molding machine manipulator uses a motor to drive the first section of the mobile arm to move up and down. Obviously, when the weight of the first section of the mobile arm is greater, the motor The greater the load driven, the greater the power consumption, and the flexibility of the motor drive to control the first section of the mobile arm to move up and down is not enough, and the work effect is not good; if a high-power motor is used to drive the first section of the mobile arm, the motor used The volume is very large and the assembly is quite inconvenient
