Full-route high-accuracy servo press mounting method

Abstract

The invention discloses a full-route high-accuracy servo press mounting method and belongs to the technical field of numerical control machine tools. The full-route high-accuracy servo press mounting method integrates advanced technologies of servo control technology, sensing technology, industrial computer control technology and the like and solves the problem of inaccurate position and bounce of press-in workpieces of the previous production process. By means of the full-route high-accuracy servo press mounting method, pressure, speed and interference magnitude can be automatically adjusted according to different gaps, different roughness and different hardness, and stable and accurate positioning accuracy can be ensured. By monitoring the pressure and displacement during the whole pressing process, workpieces deformed elastically can be pressed accurately, errors caused by manual observation can be reduced, and qualified pressing on the workpeices deformed elastically can be ensured.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a full-stroke high-precision servo pressing method based on a press. Background technique [0002] The servo press is a press that is driven and controlled by a servo motor. The servo motor can control the pressing process of the press quickly and flexibly. The most critical parameters in the pressing process of the press are the pressure, the pressing amount or the displacement of the pressure head. However, the existing servo presses do not have a device or means for monitoring the relationship between the pressure and the displacement during the entire pressing process, that is, The lack of quantitative monitoring of the overall pressing process makes it impossible to judge whether the pressure-displacement relationship in the processing process is normal or not, and whether the entire processing process is normal, which weakens the ability ...

Problems solved by technology

The most critical parameters in the pressing process of the press are the pressure, the pressing amount or the displacement of the pressure head. However, the existing servo presses do not have a device or means for monitoring the relationship between the pressure and the displacement during the entire pressing process, that is, Lack of quantitative monitoring of the overall pressing process, so that it is impossible to judge whether the pressure-displacement relationship in the processing process is normal, and whether the entire processing process is normal, which weakens the ability of the servo press to control the processing accuracy and quality

[0003] For workpieces that are elastic and deformable, it is very difficult to standardize the pressing of them, because the workpiece itself is elastic, so it is very easy to have problems such as insufficient pressing, which affects the processing accuracy of elastically deformed workpieces
