Abstract
The invention relates to a high-speed precision guiding structure. The high-speed precision guiding structure not only can realize high-precision machining, but also can bear a high-load working environment. The high-speed precision guiding structure comprises a guide post and a guide hole arranged on a body, and also comprises a gland, a sliding bearing and a rolling bearing; the gland is provided with a central hole, and is fixedly connected in the orifice of the guide hole; the sliding bearing and the rolling bearing are sequentially arranged under the gland, and are kept in axially movable connection with the guide post; the body and the sliding bearing are provided with oil holes via which the inner surface of the sliding bearing can communicate with the outside of the body; and the inner surface of the sliding bearing is provided with an oil groove. When the high-speed precision guiding structure is applied, lubricating oil enters the lubricating oil groove of the sliding bearing via an oil inlet, and when the guide post is driven by a slider to linearly move at high speed, the lubricating oil in the lubricating oil groove can rapidly bring away the heat produced by the guide post and the sliding bearing, thus guaranteeing the reliable and stable operation of the guiding structure. A seal ring in the seal gland can prevent the guide post from axially bringing out the lubricating oil, thus preventing the leakage of the lubricating oil.
Description
Technical field
The present invention relates to a kind of high speed and precision guide frame, belong 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, when bearing punching press, under the situation of shock loading, is difficult to realize accurate guiding; 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 that coefficient of friction is high, 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.
Summary of the invention
The present invention is directed to above problem, provide a kind of and can realize high-precision processing, can carry the guide frame of big load operation environment again.
Technical scheme of the present invention is: comprise lead and be arranged on the pilot hole on the body, it also comprises gland, sliding bearing and rolling bearing; Said gland is provided with mesopore, and is fixedly connected on the aperture of said pilot hole; Said sliding bearing and rolling bearing are successively set on the gland bottom, and with said lead retainer shaft to flexible connection; Said body and sliding bearing are provided with the oilhole that said sliding bearing inner surface is communicated with engine body exterior; Said sliding bearing inner surface is provided with oil groove.
Among the present invention; 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 through screw and fuselage body, simultaneously rolling bearing and sliding bearing is carried out axial restraint.Lubricating oil gets into the oil-way of sliding bearing through 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.

Fig. 1 is a structural representation of the present invention
1 is lead among the figure, the 2nd, and oilhole, the 3rd, sliding bearing, the 4th, rolling bearing, the 5th, body, the 6th, oil groove, the 7th, gland, the 8th, sealing ring.
The specific embodiment
The present invention is as shown in Figure 1: comprise lead 1 and be arranged on the pilot hole on the body 5, it also comprises gland 7, sliding bearing 3 and rolling bearing 4; Said gland 7 is provided with mesopore, and is fixedly connected on the aperture of said pilot hole; Said sliding bearing 3 is successively set on gland 7 bottoms with rolling bearing 4, and with said lead 1 retainer shaft to flexible connection; Said body 5 is provided with the oilhole 2 that makes said sliding bearing 3 inner surfaces and body 5 external communications with sliding bearing 3; Said sliding bearing 4 inner surfaces are provided with oil groove 6.For preventing that lubricating oil from leaking from the mesopore of gland 7, in gland 7 mesopores, be provided with sealing ring 8, to realize sealing.
