A control system and method for agricultural machinery chain hydraulic riveting machine

Abstract

The invention relates to a control system for a chain hydraulic riveting machine of farm machinery, and the control system comprises a program logic controller (PLC) and a sensor assembly, wherein the PLC is used for receiving a sensor signal and controls an oil cylinder to act; and the sensor assembly is used for sensing positions of a chain feeding assembly and a riveting assembly. The PLC controls a feeding ejection block oil cylinder to eject or not to eject a fixed chain ejection block according to a preset program. The control method comprises the following steps of presetting a program for the PLC; selecting one operation mode according to the production requirement; transmitting a signal to the PLC after the sensor senses the corresponding positions of the chain feeding assembly and the riveting assembly, controlling each component of the chain hydraulic riveting machine of the far machinery according to the selected preset program through the PLC, and realizing the automatic assembling of a chain of the farm machinery. By utilizing the control system and the control method provided by the invention, automatic control for riveting assembling nonstandard farm machinery chains with different specifications on the same device can be realized, the chain is easy to fix in the riveting process, the entire device can be completely automatically operated, and the production performance is stable.

Description

technical field [0001] The invention relates to the technical field of chain manufacturing, in particular to a control system and method for an agricultural machinery chain hydraulic riveting machine.

AI Technical Summary

Problems solved by technology

However, the chain links of agricultural machinery chains used for agricultural machinery are non-standard, and the structure is more complicated. The size and shape of the outer chain pieces are different, and some of them are called accessories. Compared with ordinary outer chain pieces, the shape is special. Not easy to fix

Because the existing chain riveting head equipment adopts the principle of mechanical linkage, the structure is complex, the delivery is huge, the noise is large, the action of the top block of the fixed chain is fixed, and the agricultural machinery chains for different attachments need to be assembled or replaced on different equipment. Production low efficiency
