Abstract

The utility model discloses an adjustable tailstock for a TSL. The adjustable tailstock for the TSL comprises a base and an open groove base body located on the base. A centre base which can move up and down along the groove walls on the two sides of a notch is arrange inside the notch of the base body, perpendicular key grooves are formed in the lateral wall of the centre base and the inner wall, corresponding to the lateral wall, of the notch, and keys used for fastening the centre base and the base body are installed inside the key grooves. A centre penetrates through the centre base in a parallel mode. The adjustable tailstock has the advantages that the adjustable tailstock is small in size, compact in structure and capable of being used on a small domestic machine tool while an existing adjustable tailstock can hardly be installed on the small machine tool; due to the fact that the tailstock and the centre base are located through the key grooves in the vertical direction, the horizontal location of the center base does not need manual adjustment and operation is convenient; when the tailstock is acted by external force, displacement cannot occur in the flat keys and the key grooves, and therefore high precision is guaranteed.

Description

The special-purpose adjustability tailstock of a kind of TSL

Technical field

The utility model relates to a kind of machine tool accessories, relates in particular to the special-purpose adjustability tailstock of a kind of TSL.

Background technology

Existing and TSL rotary table be used in conjunction with the tailstock volume large, quality large, operation inconvenience, special pretty troublesome when the height of manual adjustment dead head, while is the depth of parallelism of wayward its horizontal direction also, easily be subjected to displacement phenomenon, in addition, tailstock is also inharmonious in appearance with rotary table, makes a whole set of machine seem heavy.

The utility model content

The utility model purpose: the purpose of this utility model is to provide a kind of depth of parallelism without manual adjustment dead head horizontal direction, is difficult for being subjected to displacement, the degree of accuracy is high, volume is little, the special-purpose adjustability tailstock of maneuverable a kind of TSL.

Technical scheme: the special-purpose adjustability tailstock of a kind of TSL described in the utility model, comprise base and be positioned at the fluting seat body on base, the dead head that can move up and down along notch both sides cell wall is set in the notch of present body, on the sidewall of dead head with on corresponding with it notch inwall, be provided with vertical keyway, in keyway, installing for by dead head and the fastening key of seat body; The top parallel dead head that penetrates.

Wherein, on dead head, with top parallel screw-in bolt, at an end of bolt, be provided with and handle knob, this has a discoid projection on handling knob, on top, be provided with the groove that can be held into this discoid projection, discoid projection and groove fit are used, and drive top horizontal direction and move forward and backward.The equal cutting elongated groove of two cell walls of described seat body, bolt penetrate two elongated slots and dead head and by nut check.Described dead head is provided be used to clamping top clamping slot, and the notch degree of tightness of this clamping slot is regulated by bolt.On dead head, be provided be used to limiting the only hook bolt of top rotation.

The adjustable tailstock of TSL of the present utility model and TSL series panoramic table and other machine tool accessories are used in conjunction with, and can process the shaft-like workpiece with conical sliding support.

Beneficial effect: compared with prior art, its advantage is that this tailstock volume is little, compact conformation to the utility model, can use on the little lathe of less family expenses, and existing adjustable tailstock almost can't be installed on little lathe; Tailstock and dead head are located by keyway in vertical direction, and be without the artificial level orientation of adjusting dead head, easy to operate; When this tailstock was subject to External Force Acting, flat key and keyway can not be subjected to displacement, thereby guaranteed higher precision; Employing is optimized structure, and under the prerequisite that guarantees serviceability, the locking bolt is changed to the tight bolt of monolock.

The accompanying drawing explanation

Fig. 1 is stereogram of the present utility model;

Fig. 2 is top view of the present utility model;

Fig. 3 is front view of the present utility model.

The specific embodiment:

As Figure 1-3, tailstock of the present utility model comprises base 1 and the seat body 2 that is positioned at base central authorities, and U-shaped groove is opened at present body 2 centers, and dead head 3 is installed simultaneously in groove, and top 4 levels penetrate in the center hole of dead head 3.At the dead head end face, open clamping slot 10, hexagon socket head cap screw 12 by dead head 3 sidewalls during work locks top 4, the plastic deformation of dead head generation part, thereby lock toply, make it not to be subjected to displacement, guarantee the security of work, while not working, unclamp hexagon socket head cap screw 12, dead head 3 resiliences, loosen top 4.Dead head 3 can slide up and down along the U-shaped groove inwall of seat body 2, thereby regulate the height of dead head 3, specifically be achieved in that on the U-shaped groove inwall of present body 2 on the two sides with the dead head 3 that contacts with it and drive two pairs of keyways 5, keyway 5 is in vertical direction, and insert therein flat key, thereby guarantee that the present body 2 of dead head 3 is interior only lower mobile in vertical direction, be not offset, guarantee dead head 3 depth of parallelism in the horizontal direction.By present 2 liang of arm cutting elongated grooves 8 of body, outer-hexagonal bolt 9 penetrates elongated slot 8 and dead head 3, then locks dead head 3 by hex nut again.Below top 4, be parallel to top 4, to the interior screw-in bolt 6 of dead head 3, these bolt 6 one ends fixedly handle knob 7, handling knob 7 has discoid projection 7.1, on top 4, be provided with the groove 4.1 that can be held into this discoid projection 7.1, when rotation is handled knob 7 the time, discoid projection 7.1 drives grooves 4.1, thereby top 4 advance as level dead head 3 is interior, groove 4.1 only has a bit of, can avoid top 4 along with handle knob 7 the rotation, top 4 at the interior moving linearly of dead head 3, move forward and backward.In the side of dead head 3, be positioned at hexagon socket head cap screw 12 tops and insert only hook bolt 11, it is stuck in top 4, also can prevent top 4 rotations.
