Abstract

The invention discloses a jack guide sleeve tightening machine which is suitable for a jack with a piston rod set and a cylinder barrel assembled together, the head of the cylinder barrel is provided with an internal thread matched with a guide sleeve, the tail of the cylinder barrel is provided with a pin hole lug, and the outer edge of a flange of the guide sleeve is provided with a groove. An operation table of the tightening machine is provided with a clamping mechanism, a clamping mechanism and a clamping mechanism, wherein the clamping mechanism is provided with a clamping jaw for clamping a cylinder barrel; the rotation stopping mechanism is arranged on one side of the clamping mechanism and provided with a clamping unit used for clamping the pin hole lug, and a first pushing unit is arranged between the clamping unit and the operation table; and the tightening mechanism is arranged on the other side of the clamping mechanism and provided with a tightening unit used for screwing the guide sleeve, and a second pushing unit is arranged between the tightening unit and the operation table. The device is simple in structure and convenient to use, automatic tightening of the jack guide sleeve can be achieved, the labor intensity of workers is effectively relieved, and the thread tightening effect and the pre-tightening force of the guide sleeve are ensured.

Description

technical field [0001] The invention relates to the technical field of jack assembly, in particular to a jack guide sleeve tightening machine. Background technique [0002] The hydraulic support is one of the key equipments in fully mechanized coal mining, and the jack is one of the important parts of the hydraulic support, which plays a vital role in the safe and stable operation of the hydraulic support. The assembly of the jack mainly includes incoming material cleaning, piston rod assembly, cylinder piston rod assembly assembly, guide sleeve tightening, finished product pressure test, etc. Wherein, the tightening operation of the guide sleeve adopts manual operation, that is, the thread of the guide sleeve is screwed into the cylinder barrel with a bayonet wrench, and pre-tightened. The above method of manual installation of the guide sleeve cannot guarantee the thread tightening effect and pre-tightening force of the guide sleeve, resulting in lower production efficien...
