Abstract
The utility model discloses a hydraulic nut pin which comprises a cylindrical pin body, wherein the axial outer periphery of the pin body is provided with a lubricating oil groove which is arranged in a spiral line shape; and the cross section of the lubricating oil groove is semicircular, and the radius of the lubricating oil groove is 3-5mm. The hydraulic nut pin provided by the utility model is simple in structure, before installation, the spiral lubricating oil groove is filled with grease for lubrication, and during disassembly, the lubricating oil groove plays roles in cutting up impurities and storing the impurities, and the effects of the original performances are not changed, and the hydraulic nut pin is convenient to use.
Description
Technical field
The utility model relates to a kind of hydraulic nut pin.
Background technique
For a long time; Because in the steel rolling equipment system; The heavy corrosion of cooling water makes union piece hydraulic nut pin corrosion between rolling mill hydraulic nut and the rolling mill base in positioning hole, after the hydraulic nut Sealing damages; Need the hydraulic nut pin be removed, so a lot of inconvenience and helpless have been come in each periodical repair work zone of giving.
Summary of the invention
The purpose of the utility model is to provide a kind of hydraulic nut pin, and it is simple in structure, can dismantle nut pin easily, and it is time saving and energy saving to use.
The purpose of the utility model is achieved in that a kind of hydraulic nut pin, comprises the cylinder shank, and the oil groove of linear layout in the shape of a spiral is being set on the axial periphery face of shank, the cross section semicircular in shape of oil groove, and the radius of oil groove is 3-5mm.
The utility model is simple in structure, fills it up with grease lubrication in the spirality oil groove before installing, and this groove plays chopping impurity and stores it during dismounting; And do not change the effect of original performance; Owing to stored lubricating grease, significantly reduced the corrosion of steel rolling cooling water, can also part corrosion thing be stored in the spiral chute simultaneously; When preventing to dismantle in the cooperation place wedge dead, it is time saving and energy saving to use.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure schematic representation of the utility model.
