Abstract

The utility model relates to a kind of lathe knife bar, particularly relate to a kind of lathe circle shaft chisel clamping knife bar, it comprises knife bar body (1), also comprise pressing plate (2) and be positioned at 90 ° of V-type grooves (3) of knife bar body (1) end, described 90 ° of V-type grooves (3) are located on the direction of line centered by turning center height, and it is parallel with the longitudinal section of knife bar; Described pressing plate (2) has 90 ° of V-type groove (3) sides removably end with knife bar is connected.Compared with prior art, the utility model has the advantages that: achieve clamping circle shaft chisel centering, boring, save back and forth the time that dilatory tailstock is wasted, have greatly reduce labourer intensity, improve operating efficiency.

Description

Lathe circle shaft chisel clamping knife bar

Technical field

The utility model relates to a kind of lathe knife bar, particularly relates to a kind of lathe circle shaft chisel clamping knife bar.

Background technology

At present, boring on lathe, centering, turning and boring endoporus need planker combine with tailstock and use the processing that could realize part, especially present 4 used cutter spacing numerically controlled lathes.Because 4 cutter spacing numerically controlled lathes are generally with protective cover, therefore dilatory tailstock is extremely inconvenient, and particularly manufacturing batch part, needs repeatedly to draw tailstock, not only waste the time, and add labour intensity.

In prior art, knife bar can only be used for welding or clamping square blade, and the utility model by increasing a V-type groove on knife bar, achieves clamping circle shaft chisel.

Compared with prior art, the beneficial effects of the utility model are: save back and forth the time that dilatory tailstock is wasted, greatly reduce again the intensity of labourer, improve operating efficiency.

Utility model content

The purpose of this utility model is to provide a kind of simple and practical lathe circle shaft chisel clamping knife bar, and turner uses this knife bar can clamp round shaft chisel centering, boring.

In order to solve the problems of the technologies described above, the utility model by the following technical solutions, a kind of lathe circle shaft chisel clamping knife bar, comprise knife bar body, pressing plate and be positioned at 90 ° of V-type grooves of knife bar end of body, described 90 ° of V-type grooves are located on the direction of line centered by turning center height, and it is parallel with the longitudinal section of knife bar; Described pressing plate has 90 ° of V-type groove sides removably end with knife bar is connected.

Further, described pressing plate is fixed by screws in the end that knife bar has 90 ° of V-type groove sides.

During work, by required centre drill or the circle such as drill bit, milling cutter shaft chisel, put into 90 ° of V-type grooves, put pressing plate, use screw fastening pressing plate, get final product clamping complete, realize centering, boring, bore hole with vertically moving of planker.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Wherein, 1-knife bar body; 2-pressing plate; 3-90 ° of V-type groove; 4-screw.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail.

A kind of lathe circle shaft chisel clamping knife bar as shown in Figure 1, they 90 ° of V-type grooves 3 comprising knife bar body 1 and be positioned at knife bar body 1 end, described 90 ° of V-type grooves 3 are located on the direction of line centered by turning center height, and V-type groove center line is parallel with the longitudinal section of knife bar; Described lathe circle shaft chisel clamping knife bar also comprises pressing plate 2, and the end that described pressing plate 2 has 90 ° of V-type groove 3 sides by screw 4 and knife bar is connected.

During use, drill jig is held in 90 ° of V-type grooves 3, then uses screw 4 by fastening for pressing plate 2, the knife bar after fastening is arranged on lathe saddle, can machining state be entered.

The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvement, these improvement should be considered as protection domain of the present utility model.

Claims
