Abstract
The utility model discloses a tailstock with a vertical die thimble, wherein the tailstock is provided with a dovetail groove. The die thimble comprises a dovetail part and a body part. The dovetail part has an elongated structure and is inserted into the dovetail groove. The body part is combined with one end of the dovetail part in the length direction. The body part is provided with an abutting surface which is projected from the dovetail part, and a first screw hole. A height adjusting screw is arranged in the screw hole through threaded connection. Furthermore one end of the height adjusting screw is projected from the abutting surface and abuts against the surface fo the tailstock. Therefore, rigidity of the tailstock can be improved for preventing no enough clamping force of the die thimble to a workpiece.
Description
Technical field
The utility model relates to thimble, relates in particular to a kind of tailstock with vertical thimble.
Background technology
Traditional vertical thimble and tailstock combination, dovetail block there is no any structure of design and can coordinate with tailstock breasting in the back side of thimble piece, therefore this thimble will produce distortion in the time holding workpiece, seriously cause dovetail groove rhegma, the relative power deficiency that holds workpiece that causes, and impact adds the precision in man-hour, often cause workpiece to scrap.
Utility model content
The purpose of this utility model is to be to provide a kind of tailstock with vertical thimble, can increase the rigidity of thimble, to avoid thimble to occur for the problem that holds power deficiency of workpiece.
According to an aspect of the present utility model, a kind of tailstock with vertical thimble is provided, this tailstock is provided with dovetail groove, this thimble comprises dovetail portion and body, dovetail portion is strip structure and is inserted in dovetail groove, this body is incorporated into one end of the length direction of this dovetail portion, and this body has breasting face and first screw hole of this dovetail portion of a protrusion; One height adjustment screw spiral shell is located at this screw hole, and the surface of protruding this breasting face and contacting at this tailstock, this height adjustment screw one end.
In some embodiments: body is more provided with one second screw hole and a groove, this groove is communicated with this second screw hole, and this groove is installed with wherein for a thimble piece, and this second screw hole is established wherein for a fixed screw spiral shell, this fixed screw is supported this thimble piece, in order to fix this thimble piece.
The utility model is simple in structure, easy to use, can increase the rigidity of thimble, to avoid thimble to occur for the problem that holds power deficiency of workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tailstock with vertical thimble of the utility model.
Fig. 2 is the sectional view of a kind of tailstock with vertical thimble of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing explanation, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of tailstock with vertical thimble, comprise dovetail portion 11 and body 12, this dovetail portion 11 is strip structure, its cross section is trapezoidal, this body 12 is incorporated into one end of the length direction of this dovetail portion 11, this body 12 has the breasting face 121 that protrudes this dovetail portion 11, another this body 12 is provided with the first screw hole 122, the second screw hole 123 and groove 124, this groove 124 is communicated with this second screw hole 123, and this groove 124 is installed with wherein for a thimble piece 13, this second screw hole 123 is established wherein for fixed screw 15 spiral shells, this fixed screw 15 is supported this thimble piece 13, in order to fix this thimble piece 13, separation design by this thimble piece 13 with body 12, the specification of conveniently replaced this thimble piece 13 when holding the workpiece 3 of different size, preferably hold power to obtain.One height adjustment screw 14 spiral shells are located at this first screw hole 122, and this height adjustment screw 14 is installed in the height of tailstock 2 for adjusting this thimble, therefore this height adjustment screw 14 can protrude or not protrude this breasting face (121).
After this thimble 1 and tailstock 2 combine, the dovetail portion 11 of this thimble 1 is inserted in the set dovetail groove of tailstock 2 21, now the breasting face 121 of this thimble 1 is bearing on the surface of this tailstock 2, if but the withstanding part of workpiece 3 and thimble piece 13 have height fall, can be by adjusting this height adjustment screw 14, make this height adjustment screw 14 protrude from this breasting face 121 and contact at the surface of this tailstock 2, to allow the height of this thimble piece 13 can be corresponding with workpiece 3.And be bearing on the surface of this tailstock 2 or the surface conflict of height adjustment screw 14 and this tailstock 2 by this breasting face 121, all can increase this thimble 1 and support the power of this workpiece 3, the relative rigidity that has also promoted this thimble 1, and lower the active force between this dovetail groove 21 and dovetail portion 11, to avoid this dovetail groove 21 rhegmas, therefore also extended the service life of tailstock (2).
The above is only a kind of embodiment of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some similar distortion and improvement, within these also should be considered as protection domain of the present utility model.
