Abstract
The utility model discloses a triangular tailstock, which comprises a base. The base is provided with a base hole. A center sleeve capable of moving along the axis of the base hole is arranged in the base hole, a center is fixed at the front end of the center sleeve, three planes are arranged in the base hole, three planes corresponding to the three planes are arranged on the outer surface of the center sleeve, and the base hole contacts with the center sleeve through the three planes. Since the base hole of the tailstock is in contact with the center sleeve through the three planes, the linear movement of the center sleeve relative to the base hole is more stable, abrasion is uniform, position precision of the center is guaranteed well, and further machining precision and machining efficiency of a machine tool are improved.
Description
Technical field
The utility model relates to a kind of lathe, particularly relates to the tailstock of lathe.
Background technology
In lathe, tailstock is a kind of common outfit, and it be used for to support and fixation workpiece, owing to cutting force and vibrations workpiece is offset to prevent cutter when the cutting metal material.Tailstock is comprised of pedestal, top, columniform tailstock sleeve etc. usually, in the top taper hole that is fixed on tailstock sleeve, and reaches the tailstock sleeve front end, and whole tailstock sleeve places circular pedestal hole.During use, drive moving linearly in the present body opening of tailstock sleeve by various known modes, realize the top purpose of from pedestal, stretching out or retracting, with the fine setting distance between centers.Yet, above-mentioned tailstock in actual use, tailstock sleeve is because reciprocally telescopic moving from the pedestal hole, because wearing and tearing are so that the gap between the hole of tailstock sleeve and pedestal has exceeded rational scope, to such an extent as to tailstock sleeve is flexible dumb in the tailstock body opening, cause top malposition, affect machining accuracy.Simultaneously, the difficulty that the tailstock sleeve that this wearing and tearing occur is repaired is also larger, and often changing has also increased use cost virtually.
The utility model content
The technical problems to be solved in the utility model provides a kind of tailstock, and this tailstock has the high and low characteristics of use cost of quality of fit.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of triangle tailstock, comprise pedestal, has a pedestal hole on the described pedestal, be provided with the tailstock sleeve that can move along this pedestal axially bored line direction in the described pedestal hole, the front end of described tailstock sleeve is fixed with top, described pedestal has three dimensions in the hole, has three planes corresponding with this three dimensions on the outer surface of described tailstock sleeve, contacts by this three dimensions between described pedestal hole and the tailstock sleeve.
As further improvement in the technical proposal, described pedestal hole is limited and is formed by the pressing plate that is positioned at the V-type groove on pedestal top or the sidepiece plane and be fixed on this plane.
As further improvement in the technical proposal, be provided with the trip bolt for the stationary center sleeve on the described pressing plate.
Compared with prior art, the beneficial effects of the utility model are: owing to have three dimensions in the pedestal hole of the utility model triangle tailstock, have three planes corresponding with this three dimensions on the outer surface of tailstock sleeve, thereby be to contact by this three dimensions to realize guiding between pedestal hole and the tailstock sleeve, so more steady with respect to pedestal hole rectilinear motion at tailstock sleeve, wearing and tearing also can be relatively average, top positional precision be can guarantee preferably, thereby machining accuracy and the working (machining) efficiency of lathe improved.In addition, based on above-mentioned improvement, repair for worn out tailstock sleeve and also to be highly susceptible to realizing, therefore, also can well control use cost.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use was done simple declaration during the below will describe embodiment:
Fig. 1 is the structural representation of the tailstock of an embodiment of the utility model;
Fig. 2 is the vertical cross-sectional schematic of embodiment pedestal among Fig. 1;
Fig. 3 is the horizontal cross-sectional schematic of embodiment pedestal among Fig. 1;
Fig. 4 is that embodiment removes structural representation behind the tailstock sleeve among Fig. 3;
Fig. 5 is the cross section cross-sectional schematic of the tailstock sleeve of embodiment among Fig. 3.
The specific embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand fully the purpose of this utility model, feature and effect.Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.In addition, if no special instructions, the descriptions such as the connection described in the embodiment of the present application, setting, installation can be directly to connect, arrange or be installed together between two features, also can be indirectly connecting, arrange or be installed together by further feature of two features.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the triangle tailstock of an embodiment of the utility model, this tailstock comprises pedestal 10, has a pedestal hole 11 on the described pedestal 10, be provided with tailstock sleeve 20 in the described pedestal hole 11, the front end of described tailstock sleeve 20 is fixed with top 30, the rear end of described tailstock sleeve 20 is provided with screwed hole 21, one screw rod, 40 driving coupling are in this screwed hole 21, it is outer and be fixed with a handwheel 50 in its end that the tail end of described screw rod 40 reaches pedestal 10, between described pedestal hole 11 and the tailstock sleeve 20 by several plane contact.
As shown in Figure 3 and Figure 4, have three dimensions in the pedestal hole 11, have three planes corresponding with this three dimensions on the outer surface of described tailstock sleeve 20.Particularly, described pedestal hole 11 is limited and is formed by the pressing plate 60 that is positioned at the V-type groove 12 on the pedestal 10 sidepiece planes and be fixed on this plane, and like this, two planes of the inner plane of pressing plate 60 and V-type groove 12 have just formed the three dimensions in the pedestal hole 11.V type groove 12 does not need to be particularly limited its position, can be arranged at the top of pedestal 10 yet.Thus, can easily tailstock sleeve 20 parts such as grade be dismantled from pedestal 11 by removing pressing plate 60.
When rotation hand wheel 50, tailstock sleeve 20 can move by present body opening 11 cathetus, after it has arrived preposition, in order to be fixed, is provided with trip bolt 70 for stationary center sleeve 20 at pressing plate 60.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
