Description
Technical Field
The utility model relates to a machining equipment technical field specifically is a deep hole is sealed swivel sleeve of boring bar for boring machine.
Background
The deep hole boring machine adopts an oil supply device to supply oil, and the part of the rear part of the oil supply device connected with the boring rod is a rotary sealing sleeve, thereby playing two roles: 1. the boring bar is supported and guided, and the vibration of the boring bar in the machining process is reduced; 2. sealing the high-pressure cooling liquid in the oil feeder. The original rotary sealing sleeve component is shown in figure 2, and adopts a steckel seal and a Yx ring to respectively seal oil of a bearing and a rod; because the rotation of the bearing depends on the nylon taper sleeve to clamp the rod so as to drive the taper sleeve to rotate, and because the fit between the stet seal and the taper sleeve is tight, the friction force between the rod and the nylon sleeve can not drive the taper sleeve to rotate, dry friction between the rod and the nylon sleeve can be caused to generate heat expansion, and the locking between the rod and the nylon sleeve can be caused after a long time; if the fit clearance between the Stent seal and the conical sleeve is made large, the seal is not tight, oil leakage is caused, in addition, the structure has more parts, the processing is troublesome, and the cost is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sealed swivel mount of boring bar for deep hole boring machine to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a sealed rotary sleeve of a boring rod for a deep hole boring machine comprises: the oil supply device comprises an oil supply device shell, a rear cover shell, a deep groove ball bearing seat, a boring rod supporting sleeve, a boring rod and a sealing element, wherein the rear end of the oil supply device shell is provided with an opening, the rear cover shell is fixedly connected to the opening of the oil supply device shell through bolts, the outer side of the deep groove ball bearing seat is fixedly connected into a stepped hole in the front end of the rear cover shell, the boring rod supporting sleeve is fixedly connected to the inner side of the deep groove ball bearing seat, the boring rod is sleeved in the boring rod supporting sleeve, and the sealing element is arranged at the connecting position between the boring rod and the rear cover shell.
Furthermore, the front end of the rear cover shell is fixedly connected with a bearing gland through a bolt.
Compared with the prior art, the beneficial effects of the utility model are that: the boring rod sealing rotary sleeve for the deep hole boring machine cancels a taper sleeve structure, is changed into a straight sleeve, and adopts cast iron material, thereby preventing the gluing phenomenon of the boring rod in the rotating process; the bearing is changed into a common deep groove ball bearing, the starting torque is small, the rotation is flexible, and the sealing element is only acted between the boring bar and the rear cover shell; the structure only has three machined parts, has low requirement on machining precision, and greatly reduces the cost compared with the original structure.
The utility model has the advantages of simple structure, convenient assembly, low cost, etc.
