DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] In order to make the purpose, technical solutions, and advantages of the utility model implementation cases clearer, the following will, in combination with the accompanying drawings in the implementation cases, clearly and completely describe the technical solutions in the implementation cases of the present utility model. Obviously, the described implementation cases are a small part of the implementation cases of the present utility model, rather than all of them. Based on the implementation cases in the present utility model, all other implementation cases obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0018] An automatic oiling and lubricating device for a rolling mill includes an installation frame 2. A driving motor 3 is fixedly installed on the outer wall of one side of the installation frame 2. One end of the output shaft of the driving motor 3 is fixedly installed with an installation shaft 5. A rolling roll 1 and two side pressure cams 6 are fixedly installed on the outside of the installation shaft 5. A supplementary oil component 4 and an automatic oiling component 7 are fixedly installed in the housing cavity of the installation frame 2. The supplementary oil component 4 is located below the automatic oiling component 7.
[0019] The automatic oiling component 7 includes an oil box 78. The oil box 78 is fixedly installed in the housing cavity of the installation frame 2. A fueling pipe 79 is fixedly installed on the outer wall of one side of the oil box 78. One end of the fueling pipe 79 passes through and extends to the outside of the installation frame 2.
[0020] Above the oil box 78, an oil guiding sleeve 76 is fixedly installed through an oil guiding pipe 77. The oil guiding sleeve 76 is sleeved on the outside of the installation shaft 5. A side cover 73 is fixedly installed on one side of the oil box 78. A middle partition plate 75 is fixedly installed on the outer wall of one side of the side cover 73. A pressure oil piston 74 is slidably installed between the middle partition plate 75 and the side wall of the oil box 78.
[0021] A piston rod 710 is fixedly installed on the outer wall of one side of the pressure oil piston 74. The piston rod 710 is slidably connected to a sliding hole provided in the side cover 73. A sleeve spring 71 is sleeved on the outside of the piston rod 710. One end of the piston rod 710 is fixedly installed with a side pressure plate 72.
