Description

Technical Field

[0001] This invention relates to the field of tightening machine technology, and in particular to an automatic guide sleeve tightening machine. Background Technology

[0002] Currently, the assembly process for large hydraulic support cylinder column guide sleeves involves inserting the large guide sleeve between the outer and middle cylinders, and the small guide sleeve between the middle cylinder and the piston. For column guide sleeve assembly equipment, the market mainly offers semi-automatic cylinder column guide sleeve assembly equipment. Manual lifting is used to place the column and guide sleeve in their corresponding positions on the guide sleeve assembly equipment. The operator controls the installation via buttons and observes the guide sleeve as it is threaded downwards. If manual observation is inaccurate, and the guide sleeve is installed before the thread is fully threaded, it can damage the sealing ring. Furthermore, the threading process is slow, reducing labor efficiency and productivity. Therefore, we propose an automatic guide sleeve tightening machine. Summary of the Invention
