The utility model content

Technical problem to be solved in the utility model is: a kind of vertical broaching machine lubricating arrangement is provided, and this device can satisfy lubrication needs by less oil filler point is set, thereby has avoided the leakage of lubricating oil and distributed the uneven insufficient lubrication that causes.

For solving the problems of the technologies described above, the technical solution of the utility model is: the vertical broaching machine lubricating arrangement, comprise vertical guide rail that fixedly installs and the dovetail that is in contact with it and moves reciprocatingly, have oil filler point on the described dovetail, have oil groove on described dovetail and the contacted surface of described guide rail, be provided with the oil duct that is communicated with described oil filler point and oil groove in the described dovetail.

As a preferred implementation, described oil filler point is positioned at the upper surface of described dovetail.

As a preferred implementation, the limit of sports record position of described dovetail is between the upper and lower end face of described guide rail.

As a preferred implementation, described oil groove is bending.

After having adopted technique scheme, the beneficial effects of the utility model are: because oil filler point is arranged on the dovetail, oil groove is arranged on dovetail and the contacted surface of guide rail, dovetail inside is provided with the oil duct that is communicated with oil filler point and oil groove simultaneously, when then lubricated, only less oil filler point need be set, make lubricating oil on average flow to each contact-making surface then along the oil duct of dovetail inside, thereby realize distribute lubrication oil equably, reduce the insufficient lubrication that causes because of the distribution of lubrication oil inequality, also avoided the leakage of lubricating oil.

Since this method broken originally on guide rail, be provided with oil groove lubricating method, oil groove only is set on dovetail, the limit of sports record position of dovetail is between the upper and lower end face of guide rail simultaneously, thereby in lubricated process, even if dovetail moves to extreme position, oil groove and lubrication hole can not come out all the time yet, thereby have both avoided the generation of Integrated Chip problem, have prevented that again dust and impurity particle from damaging contact-making surface.
