Press-fitting control system and method

Abstract

The invention discloses a press-fitting control system and a corresponding press-fitting control method. The system comprises a press-fitting execution assembly and a press-fitting control assembly, wherein the press-fitting control assembly is connected with the press-fitting execution assembly and used for controlling the operation of the press-fitting execution assembly; the press-fitting control assembly comprises a PLC control device and a PC control device, and the PLC control device is connected with the PC control device; the PLC control device comprises a central processing unit, a digital quantity input module and a digital quantity output module; and the PC control device comprises an industrial control all-in-one machine, a digital quantity input board card, a digital quantityoutput board card, an analog quantity input board card and an analog quantity output board card. According to the press-fitting control system and the corresponding press-fitting control method, the concept of PC control is introduced, and the control over the whole hydraulic press-fitting process is realized by using the mode of combining the PLC control device and the PC control device.

Description

technical field [0001] The invention relates to a control system and a corresponding control method, in particular to a press-fit control system and a press-fit control method, belonging to the field of industrial automation. Background technique [0002] With the development of the times and the continuous improvement of industrial production levels, the processing technology of products designed and manufactured by various industrial production enterprises is becoming more and more complex, and the requirements for the assembly and processing of various parts in the products are becoming more and more stringent. Specifically, in the process of product processing, the press-fitting between parts is a very important process, and it is also an important condition to ensure the product qualification rate. Under normal circumstances, processing companies will purchase corresponding hydraulic equipment to perform parts press-fitting operations according to the product needs of d...

Problems solved by technology

It can also be seen from the above requirements that the existing hydraulic press-fitting equipment is difficult to meet the needs of today's use, and its shortcomings are mainly reflected in the following aspects:

[0005] 1. The PLC and touch screen in the existing equipment do not have the function of data storage, so they cannot store various data during the pressing process;

[0006] 2. In the existing equipment, the data transmission efficiency between the PLC and the force and displacement sensors on the equipment is low, the data reading speed is very slow, and the amount of data read per unit time is very small;

[0007] 3. Using PLC to read the data in the force and displacement sensor, the real-time performance during the whole operation process is poor, and there will be a time difference when analyzing the data, which will reduce the accuracy and real-time performance of the system feedback;

[0008] 4. The information content displayed on the touch screen in the existing equipment is limited in quantity, it is difficult to achieve complete feedback on feedback information and operation information, and the entire information configuration process is not flexible enough
