Abstract
The utility model discloses a lathe tailstock sleeve, which comprises a sleeve body, wherein a fastening sleeve is movably connected to the front end of the sleeve body; and an inner hole of the sleeve body is a mold hole. According to the lathe tailstock sleeve, the original tailstock sleeve is changed into the mold hole, and the end parts of a taper shank and a screw rod of a drill bit are correspondingly improved, so that the using effect is good, the taper shank of the drill bit no longer rotates in a sleeve hole when a big hole is drilled, the problem of grinding damage of a taper hole of the sleeve is solved, and the lathe tailstock sleeve is simple in structure, low in cost, convenient to operate, safe and reliable; the fastening sleeve is movably connected to the front end of the sleeve body, so that the supporting surface of the sleeve is extended, thereby avoiding the problem of low processing precision caused by vibration of the sleeve; and even if the fastening sleeve is abraded and the processing precision is influenced, only the fastening sleeve needs to be replaced, so that the lathe tailstock sleeve is very convenient to use.
Description
Technical field
The utility model belongs to the technical field of lathe, relates in particular to a kind of tail stock sleeve.
Background technology
The design tail stock must guarantee the lathe positioning accuracy.Tail stock is when boring macropore, and due to the friction torque of the cutting moment of torque greater than taper shank, drill taper shank is moving in the transfer of sleeve taper hole, cause that sleeve taper hole and drill bit tapering grind wound, Machine Tool Positioning Accuracy is reduced, and the moment of torsion of taper shank transmission reduces greatly, bores macropore just more and more difficult.Reconditioning sleeve taper hole is more nerve-racking problem in present repair work.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of tail stock sleeve, prevents that drill taper shank is moving in the transfer of sleeve taper hole.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of tail stock sleeve, comprise cylindrical shell, and the front end of described cylindrical shell is connected with adapter sleeve, and the endoporus of cylindrical shell is the type hole.
Compared with prior art, the utility model has the advantage of: 1, original barrel of tail stock is changed into the type hole, corresponding improvement is also done in the taper shank end of drill bit and screw mandrel end, result of use is good, and when boring macropore, drill taper shank no longer rotates in sleeve hole, has solved grinding of sleeve taper hole and has hindered problem, and simple in structure, with low cost, easy to operate, safe and reliable.2, the front end of cylindrical shell is connected with adapter sleeve, and the bearing-surface of sleeve is extended, thereby avoids vibrating because of sleeve the problem of the machining accuracy reduction that causes, and is even when affecting machining accuracy in fastening cylinder wearing and tearing, only need get final product by the fastening cylinder of replacing, very convenient.
Further, for convenient processing, described endoporus is the tang shape.
Description of drawings
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of the utility model tail stock sleeve embodiment;
Fig. 2 is the left view of the utility model tail stock sleeve embodiment.
The specific embodiment
As depicted in figs. 1 and 2, the tail stock sleeve in the present embodiment comprises cylindrical shell 1, and the front end of described cylindrical shell 1 is connected with adapter sleeve 2, and the endoporus of cylindrical shell 1 is the type hole.For convenient processing, described endoporus is the tang shape.
The present embodiment changes original barrel of tail stock into the type hole, corresponding improvement is also done in the taper shank end of drill bit and screw mandrel end, result of use is good, when boring macropore, drill taper shank no longer rotates in sleeve hole, solve grinding of sleeve taper hole and hindered problem, and simple in structure, with low cost, easy to operate, safe and reliable.The front end of cylindrical shell 1 is connected with adapter sleeve 2, and the bearing-surface of sleeve is extended, thereby avoids vibrating because of sleeve the problem of the machining accuracy reduction that causes, and is even when affecting machining accuracy in fastening cylinder wearing and tearing, only need get final product by the fastening cylinder of replacing, very convenient.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. a tail stock sleeve, comprise cylindrical shell, it is characterized in that: the front end of described cylindrical shell is connected with adapter sleeve, and the endoporus of cylindrical shell is the type hole.
2. tail stock sleeve as claimed in claim 1, it is characterized in that: described endoporus is the tang shape.
