C-shaped precision servo press

Abstract

The invention discloses a C-shaped precision servo press which is characterized in that a main frame is used as an integral support, an electrical cabinet is used for controlling a servo electric cylinder, and press fitting processing of the press is completed through cooperation of the servo electric cylinder and a workbench. The problem that the control accuracy is affected by elasticity of compressed gas and response lag of a hydraulic system is effectively solved. In addition, the press machine adopts the square piston rod, a piston rod in an existing servo electric cylinder is improved from a round shape to a square shape, longitudinal line contact of the existing round piston rod is upgraded to longitudinal face contact of the square piston rod, and the overall unbalance loading resisting capacity and precision of the press machine are greatly improved. An accurate and stable effect on constant-pressure and constant-stroke operation control is achieved; the press machine has the advantages of being simple in structure, reasonable in design, high in practicability, resistant to rotation, good in deflection resistance, high in precision and the like.

Description

technical field [0001] The invention discloses the technical field of servo presses, in particular to a C-type precision servo press, including a four-column press and a frame press. Background technique [0002] Servo press usually refers to a press that uses a drive motor for drive control. C-type servo press belongs to a small press, which is mainly used for the processing of pressure medicine and parts in the industry and the assembly and process of bearings. With the rapid development of assembly and manufacturing and the continuous improvement of living standards, people have higher requirements for product quality. For the assembly of parts such as bearings, screws, and plug-ins, it is not only required to control the assembly force of the result, but also to control the force and displacement of the assembly process, so it puts forward higher requirements for assembly equipment. [0003] The existing press-fitting equipment is mainly realized by pneumatic cylinders ...

AI Technical Summary

Problems solved by technology

[0003] The existing press-fitting equipment is mainly realized by pneumatic cylinders and hydraulic cylinders. The problem brought about by this method is that the press-fitting force changes with the change of air pressure and hydraulic pressure. However, it is difficult to accurately control the air pressure and hydraulic pressure. And the cost is very high; in addition, the elasticity of the compressed gas and the response hysteresis of the hydraulic system all lead to the inability to accurately control the pressing position
