Abstract
本实用新型公开了一种钻孔深度套筒，它包括钻头套筒(3)，所述钻头套筒通过紧固螺钉(1)、(4)固定在钻柄(2)上。本实用新型提供在C615车床上加工紧定螺母，精确加工固定深度的小孔提供了辅助工具。结构设计合理，操作简单，工作效率高，加工后得到的工件的形位公差小，不易造成孔深度不精确而导致的报废等。加工得到的小孔工件质量高，精度高，实用性较强。
The utility model discloses a drilling depth sleeve, which comprises a drill bit sleeve (3), and the drill bit sleeve is fixed on a drill handle (2) through fastening screws (1) and (4). The utility model provides an auxiliary tool for processing a set nut on a C615 lathe, precisely processing a small hole with a fixed depth. The structure design is reasonable, the operation is simple, the work efficiency is high, the shape and position tolerance of the workpiece obtained after processing is small, and it is not easy to cause scrapping caused by inaccurate hole depth. The processed small hole workpiece has high quality, high precision and strong practicability.
Description
Technical field
This utility model relates to a kind of machinery, is specifically related to a kind of drilling depth sleeve.
Background technology
In machining, normally used parallel shank twist drill is when boring, is all to clamp the staight shank of fluted drill directly to part implementation boring with three-jaw drill chuck.Either using pneumatic drill or machining apparatus, boring is nearly all driven straight in, and the degree of depth of boring is all the degree of depth that manually experience grasp and continuous dimensioning carry out keyhole.If assembling boring between Drilling operation two interlayer when, operator are not in order to injure the surface of lower floor it is necessary to the degree of depth of keyhole of extreme care, even if the operator known a thing or two, it also is difficult to the surface controlling not injure second layer part, quality problems occur.
Utility model content
The degree of depth uppity weak point when the purpose of this utility model is to improve C615 lathe boring, it is provided that a kind of aid that can freely regulate bit operation length.
Technical scheme: in order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of adjustable positioning drill holder, by its fixed position on drillstock of trip bolt scalable.
Preferably, with two dregs guiding grooves in the middle of the above sleeve.
Preferably, described sleeve afterbody has two trip bolts.Sleeve can be fixed on drillstock (2) by trip bolt.
Preferably, sleeve afterbody, there is rubber sheet gasket, it is simple to fastening on the downside of trip bolt.
Preferably, bush material select 9CrSi, heat treatment hardness HRC60～64, deform little, wearability is high.
Beneficial effect: compared to the prior art the bit depth sleeve barrel tool that this utility model provides has the advantage that
The degree of depth of this utility model convenient control and regulation boring, improves working (machining) efficiency and quality, reduces mismachining tolerance, be convenient for measuring, especially assembling boring between Drilling operation two interlayer when, will not destroy underlying surfaces.
Accompanying drawing explanation
The structural representation of a kind of drilling depth sleeve that Fig. 1 provides for this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
Fig. 1 describes the preferred example of the scalable locating drilling head that this utility model is mainly made up of drill bit (2) and degree of depth spacing collar (3).Sleeve can slide on drill bit, has the trip bolt (1) (4) of two mating sleeve work at deep sleeve afterbody.Being loaded by drill bit during work in degree of depth spacing collar (3), regulation drill bit stretches out spacing collar length according to demand, then locks with trip bolt (1) (4), can process workpiece.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
