Description

Technical Field

[0001] The utility model relates to a thin oil lubrication quick joint disassembly tool for a rolling mill working roll, belonging to the technical field of maintenance of rolling mill roll bearing lubrication equipment in the metallurgical industry. Background Art

[0002] Refer to the attached Figure 1 , 2 In cold rolling production, the lubrication of the thrust bearing seat of the working roll of the rolling mill is centralized thin oil lubrication. The lubricating oil is output to the main pipeline through the rotation of the main pump, and then flows through the joint connecting arm after the pressure is adjusted by the regulating valve. Through the female head fixed on the connecting arm and the male head on the bearing seat, the lubricating oil is transported to the bearing seat to provide lubrication for the roller thrust bearing.

[0003] Since the rolls need to be replaced regularly according to the rolling mileage, each time the rolls are changed, the working roll locking hydraulic cylinder drives the joint connecting arm to open, and the male and female quick connectors disengage. After the rolls are pulled out and replaced with new working rolls, the locking action of the working roll locking hydraulic cylinder drives the joint connecting arm to lock the male and female heads, and the lubricating oil is connected and flows into the bearing seat.

[0004] It was found during use that due to frequent roller changes, the male and female heads of the quick connector often become damaged after being engaged for a period of time. Once the quick connector is damaged, an accident of lubricating oil leakage will occur. Therefore, when the quick connector is damaged, it is necessary to replace the male and female heads of the quick connector in time. Due to the compact structure and small space of the rolling mill locking block, each time the quick connector is replaced, it is necessary to first disassemble the connector arm, and then disassemble the quick connector threaded thereon for replacement. Each replacement is time-consuming and laborious. In order to reduce the accident time of each replacement of the quick connector, it is urgently necessary to design a special tool for quickly replacing the lubricating oil quick connector. Utility Model Content

[0005] The utility model aims to provide a rolling mill working roll thin oil lubrication quick joint disassembly tool, which can quickly disassemble and assemble the rolling mill working roll thin oil lubrication quick joint and solve the problems existing in the background technology.

[0006] The technical solution of the utility model is:

[0007] A thin oil lubricated quick connector disassembly tool for a rolling mill working roll comprises a handle, a dovetail slider, a positioning screw and a locking screw. One end of the handle is cylindrical and the other end has a trapezoidal cross section. The end of the handle with a trapezoidal cross section serves as a dovetail track. Two dovetail sliders are respectively arranged on the dovetail tracks. A positioning screw and a locking screw are provided between each dovetail slider and the dovetail track.

[0008] The dovetail track is provided with a long strip through hole matching the positioning screw, and the dovetail slider is provided with a positioning threaded hole matching the positioning screw and a locking screw hole matching the locking screw.

[0009] The positioning threaded hole on the dovetail slider that matches the positioning screw and the locking screw hole that matches the locking screw are both through holes that penetrate the dovetail slider.

[0010] The long strip through hole on the dovetail track matching the positioning screw is arranged along the length direction of the handle.

[0011] The dovetail type sliding block is provided with a dovetail groove matching the dovetail track.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is easy to use, and the opening degree of the dovetail type slider can be adjusted according to the size of the quick connector, so as to achieve the purpose of quickly disassembling and assembling the quick connector, reduce the accident time of handling the oil leakage of the quick connector, and ensure the stable operation of production.
