Abstract
The utility model discloses an alignment device for a square workpiece. According to the alignment device for the square workpiece, three top claws of a lathe chuck are utilized for aligning the workpiece. The ends of the workpiece have four outer right angles. The alignment device for the square workpiece comprises a hollow cylinder, the hollow cylinder is equally divided into three parts along the axis of the cylinder to form a first fan-shaped body, a second fan-shaped body and a third fan-shaped body, meanwhile, the interior of the first fan-shaped body, that of the second fan-shaped body and that of the third fan-shaped body are respectively provided with an inner right angle matched with one outer right angle of the workpiece, and the fourth outer right angle of the workpiece is located between the first fan-shaped body and the second fan-shaped body; besides, the outer side face of the first fan-shaped body, that of the second fan-shaped body and that of the third fan-shaped body are respectively matched with one top claw. The alignment device for the square workpiece has the advantages that the machining efficiency of the square workpiece can be improved.
Description
Technical field
The utility model relates to the frock technical field, especially relates to a kind of alignment device of square cross.
Background technology
The method of processing square shaft class miniature workpiece is on lathe: first use chuck centering workpiece, machining center hole and spindle nose, with same method processing other end centre bore, then change scroll chuck and clamp spindle nose, with tailstock centre, hold out against other end centre bore and process.Like this, need frequent replacing three-jaw, chuck, thereby working (machining) efficiency is low, comparatively loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to provide a kind of alignment device of square cross, and it has the characteristics of the working (machining) efficiency that can improve square cross.
the technical scheme that the utility model adopts is: the alignment device of square cross, in order to three top pawls that utilize lathe chuck, workpiece is carried out to centering, the termination of this workpiece has 4 outer right angles, the alignment device of described square cross comprises an inner penetrating cylinder, this cylinder forms the first segment after its axial line is divided into 3 equal portions, the second segment and the 3rd segment, simultaneously, this is first years old, second, the inside of the 3rd segment has respectively one and the interior right angle that matches, 1 outer right angle of this workpiece, and the 4th outer right angle of this workpiece is positioned at this first segment, between the second segment, and, this is first years old, second, lateral surface respectively with the one top pawl of the 3rd segment matches.
Described cylindrical outside is provided with a limited step.
The advantage that compared to the prior art the utility model has is: the working (machining) efficiency that can improve square cross.After three segments of the alignment device of square cross of the present utility model (comprising the first segment, the second segment, the 3rd segment) are wrapped in the outside of this workpiece, be equivalent to make this square workpiece to have circular outer surface, and then can carry out centering to this workpiece by the scroll chuck of lathe, without using chuck, avoided the frequent replacing of three-jaw, chuck, the operating efficiency while then having improved the square workpiece of lathe processing.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is that the alignment device of square cross of embodiment of the present utility model is at the front view of application state;
Fig. 2 is the front view of alignment device of the square cross of embodiment of the present utility model;
Fig. 3 is the right view of Fig. 2.
In figure: 10, cylinder, the 11, first segment, the 12, second segment, the 13, the 3rd segment, 14, interior right angle, 15, limited step; 100, lathe chuck, 101, the top pawl; 200, workpiece, 201, outer right angle.
The specific embodiment
Embodiment, be shown in that Fig. 1 is to shown in Figure 3: the alignment device of square cross, in order to the 101 pairs of workpiece of three top pawls 200 that utilize lathe chuck 100, carry out centering, the termination of this workpiece 200 has 4 outer right angles 201.That is the lathe chuck 100 here refers to scroll chuck, and the workpiece 200 here refers to square cross.Concretely, the alignment device of this square workpiece comprises an inner penetrating cylinder 10, and this cylinder 10 forms the first segment 11, the second segment 12 and the 3rd segment 13 after its axial line is divided into 3 equal portions.Simultaneously, the inside of this first segment 11, the second segment 12, the 3rd segment 13 has respectively one and 1 interior right angle 14 that outer right angle 201 matches of this workpiece 200, and the 4th outer right angle 201 of this workpiece 200 is between this first segment 11, the second segment 12, and lateral surface respectively with the one top pawl 101 of this first segment 11, the second segment 12, the 3rd segment 13 matches.That is, these 3 top pawls 101 withstand on respectively on the lateral surface of this first segment 11, the second segment 12, the 3rd segment 13.Like this, be equivalent to make the cross section of square workpiece 200 to be become as circle by square, thereby make this scroll chuck carry out centering to this square workpiece 200.
Optimize, the outside of this cylinder 10 is provided with a limited step 15.That is, an end face of this limited step 15 can withstand on the end face of this lathe chuck 100, makes the position of this cylinder 10 comparatively stable.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
