Abstract
A deep hole drill bit guide sleeve is composed of a guide sleeve (1), a drill bit converter (2) and a sealing ring (3). The guide sleeve (1) adopts a step type large- and small-end structure. A transition fit is provided between an inner hole on the small end of the guide sleeve and the drill bit converter (2). The deep hole drill bit guide sleeve is characterized in that the sealing ring (3) is equipped between the guide sleeve (1) and the drill bit converter (2). The sealing ring is required in a guider due to the fact that a deep hole drill bit is cooled by high-pressure oil. The guide sleeve provided in the utility model ensures that no high-pressure oil will spray out during a processing course of the guider. Meanwhile, the guide sleeve which has the advantages of simple manufacturing process, working stability and reliability, and low cost obviously lowers the reject ratio generated by high-gradient curved face processing or small planar hole processing.
Description
Technical field
The utility model relates to deep hole drilling machine drill bit guider, is mainly used in processing small holes on big slope curved surface or the plane.
Background technology
In the depth drill boring process; Big slope curved surface or the facet hole adds man-hour; Because former drill bit clamping device tool setting plane is bigger; When processing big slope curved surface or facet hole, drill bit is owing to contact with big slope curved surface, causes unbalance stress to be prone to take place that tool setting is inaccurate, drill bit fractures and break the generation that workpiece etc. is processed bad phenomenon.
Summary of the invention
To above deficiency; The purpose of the utility model is to provide a kind of depth drill drill bit fairlead; Be through changing original guider structure,, reduce the bad phenomenon that depth drill is occurred as far as possible when big slope of processing or facet hole to improve the force-bearing situation of drill bit in the process.
The technical scheme of the utility model realizes in the following manner: depth drill drill bit fairlead, by
Fairlead, drill bit converter, sealing ring are formed, and it is the concentric reducer structure that fairlead adopts step, and the endoporus of small end and drill bit converter are interference fits, it is characterized in that: be provided with sealing ring between described fairlead and the drill bit converter.
Described end diameter is 1/2 of the original-pack fairlead diameter of lathe.
The beneficial effect of the utility model is: because the depth drill drill bit cools off through hydraulic oil, this guider must increase sealing ring, has guaranteed that guider does not have the hydraulic oil ejection in process.And manufacturing process is simple, and working stability is reliable, and cost is low.Can significantly reduce the fraction defective of big slope curved surface or facet hole processing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Depth drill drill bit fairlead is made up of fairlead 1, drill bit converter 2, sealing ring 3, and it is the concentric reducer structure that fairlead 1 adopts step; End diameter is 32mm, is merely 1/2 of the original-pack fairlead diameter of lathe, when big slope curved surface or facet deep hole machining; Can shorten the distance of drill bit cutting edge to end face; The moment of drill bit blade is reduced, alleviate the bit force situation thus, process is steadily carried out.Drill bit converter 2 can be equipped with plurality of specifications according to different depth drill specifications, to satisfy the production needs.
Claims (2)
1. depth drill drill bit fairlead; Form by fairlead (1), drill bit converter (2) and sealing ring (3); It is the concentric reducer structure that fairlead (1) adopts step; The endoporus of small end and drill bit converter (2) are interference fits, it is characterized in that: be provided with sealing ring (3) between described fairlead (1) and the drill bit converter (2).
2. according to the said depth drill drill bit of claim 1 fairlead, it is characterized in that: described fairlead (1) end diameter is 1/2 of the original-pack fairlead diameter of lathe.
