Description

Technical Field

[0001] The utility model relates to the technical field of application of a sliding nozzle oil cylinder, in particular to a positioning and fixing device for a sliding nozzle oil cylinder. Background Art

[0002] The sliding nozzle oil cylinder is mainly composed of a piston rod, a cylinder body, a gland, a guide sleeve, a piston, and a high-temperature seal. The high-temperature seal is made of fluororubber. The oil cylinder can work normally and continuously at 200°C. After removing the sliding nozzle oil cylinder, it needs to be fixed and limited to prevent the sliding nozzle oil cylinder from moving. The existing patent (Announcement No.: CN115533788B) discloses a positioning and fixing device for a sliding nozzle oil cylinder. The invention can fix and limit cylinders of different diameters through the coordinated operation between a support plate, a sliding rod, a clamping block, a rotating block, a screw, a pulley group, a slide plate, a pressure block, and a card plate, thereby expanding the scope of application. However, in actual applications, when the diameter of the oil cylinder is different, the contact surface between the arc-shaped clamping block and the oil cylinder is very limited, which makes the fixing and limiting effect of the oil cylinder insufficient. Therefore, the technical solution of the above invention adopts a pressure block to make up for this defect, but it complicates the structure of the positioning and fixing device, and is not conducive to the normal heat dissipation of the oil cylinder that has just finished working. To this end, we propose a positioning and fixing device for a sliding nozzle oil cylinder. Utility Model Content
