Abstract
The utility model relates to a high-speed precision guide structure. The high-speed precision guide structure not only can realize high-precision processing, but also can bear a high-load working environment. The high-speed precision guide structure comprises a guide pillar, a guide hole arranged on a machine body, a gland, a sliding bearing and a rolling bearing, wherein the gland is provided with a middle hole an is fixedly connected with an orifice of the guide hole; the sliding bearing and the rolling bearing are arranged at the lower part of the gland sequentially and are kept in axial movable connection with the guide pillar; the machine body and the sliding bearing are provided with oil holes for ensuring the inner surface of the sliding bearing to be communicated with the outside of the machine body; and the inner surface of the sliding bearing is provided with an oil tank. In the application of the high-speed precision guide structure, lubricating oil enters the lubricating oil tank of the sliding bearing through an oil inlet; when a sliding block partly drives the guide pillar to take the high-speed straight-line motion, the lubricating oil in the lubricating oil tank can rapidly take away heat generated by the sliding bearing through the guide pillar so as to ensure that the guide structure is reliable and stable to operate. A sealing ring in a sealing gland is used for preventing the guide pillar from axially taking away the lubricating oil and preventing the lubricating oil from being leaked out.
Description
Technical field
The utility model relates to a kind of high speed and precision guide frame, belongs to the press technologies category.
Background technology
In the forcing press field, for realizing the operation of high accuracy, heavy load, the guide frame of axially-movable has only two kinds of forms, and a kind of is the guiding of rolling; A kind of is slide-and-guide.The advantage of rolling guide frame is that coefficient of friction is low, and heating is few, is easy to realize high-speed cruising, and shortcoming is that the rated load that can bear is low, under the situation of shock loading, is difficult to realize accurate guiding when bearing punching press; The advantage of gliding movement targeting structure is that to bear load capacity strong, is out of shape for a short time, is easy to realize accurate guiding, and shortcoming is the coefficient of friction height, and caloric value is big, and when high-speed cruising, heat is not easy to distribute fast, causes targeting part inordinate wear or fatal damage to occur.
The utility model content
The utility model provides a kind of and can realize high accuracy processing at above problem, can carry the high speed and precision guide frame of big load operation environment again.
The technical solution of the utility model is: comprise lead and the pilot hole that is arranged on the body, it also comprises gland, sliding bearing and rolling bearing; Described gland is provided with mesopore, and is fixedly connected on the aperture of described pilot hole; Described sliding bearing and rolling bearing are successively set on the gland bottom, and with described lead retainer shaft to flexible connection; Described body and sliding bearing are provided with the oilhole that described sliding bearing inner surface is communicated with engine body exterior; Described sliding bearing inner surface is provided with oil groove.
In the utility model, the lead upper end is fixedly connected with press ram part (moving part), rolling bearing and sliding bearing and fuselage body endoporus precision-fit, sealing gland is fixed by screw and fuselage body, simultaneously rolling bearing and sliding bearing is carried out axial restraint.Lubricating oil enters the oil-way of sliding bearing by oil-in, when Slipper drive lead is done the high-speed straight-line motion, lubricating oil in the oil-way can be taken away through the heat of lead and sliding bearing generation fast, has guaranteed the operation that guide frame is reliable, stable.Sealing ring in the sealing gland prevent lead with lube shaft to taking out of, prevent oil leak.
