Abstract

The utility model discloses a supplementary rotation angle's bulb round pin in numerical control. Include the bulb, be located the reference surface of terminal surface lies in under the bulb the axis of reference of terminal surface under the reference surface, the coaxial setting in axle center of the centre of sphere of bulb, the center of reference surface and axis of reference. Bulb, reference surface and axis of reference are the integrated into one piece structure. The utility model discloses following beneficial effect has: use the utility model discloses again, alignment labour saving and time saving is accurate simple and easy through the supplementary rotation angle of bulb round pin, the effect ideal.

Description

The ball head pin of auxiliary angle of rotation in a kind of numerical control

Technical field

The utility model relates to the ball head pin of auxiliary angle of rotation in a kind of numerical control.

Background technology

In vehicle mould numerical control, often can run into the profile of wall or negative angle, need to by insert angle of rotation. Before angle of rotation, selecting position useless in insert profile, make a call to a heavy head bore, wherein, heavy head bore diameter 31mm, bottom diameter 10mm, heavy head bore bottom surface needs accurately, and bottom diameter also needs to process by the tolerance of H7. Insert looks for positive method to have much after rotating again, has by reference plane, also has by side reference axis, but all time-consuming, require great effort, effect not ideal enough.

In view of this, it is necessary to provide a kind of new technical scheme to solve the problem in fact.

Practical novel content

Practical novel object: a kind of ball head pin that can accurately look for auxiliary angle of rotation in positive numerical control is provided.

For solving the problems of the technologies described above, the embodiment of the present application provides: the ball head pin of auxiliary angle of rotation in a kind of numerical control, comprises bulb, is positioned at the reference plane of described bulb lower surface, be positioned at the reference axis of described reference plane lower surface; The axle center of the centre of sphere of described bulb, the center of reference plane and reference axis is coaxially arranged.

Can selection of land, described bulb, reference plane and reference axis are formed in one structure.

Compared with prior art, the utility model has following useful effect:

The utility model is used just again to look for, time saving and energy saving, by the auxiliary angle of rotation of ball head pin, accurately simple and easy, satisfactory for result.

Accompanying drawing explanation

Some specific embodiments of the present invention are hereinafter described with reference to the accompanying drawings by way of example, and not by way of limitation in detail. Reference numeral identical in accompanying drawing denotes same or similar parts or part. Those skilled in the art should understand that, these accompanying drawings may not be drawn in proportion. In accompanying drawing:

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

Fig. 2 is using state figure of the present utility model.

In the drawings, 1, bulb, 2, reference plane, 3, reference axis, 4, ball head pin.

Embodiment

For making the object of the application, technical scheme and advantage clearly, below in conjunction with the application's specific embodiment and corresponding accompanying drawing, technical scheme is clearly and completely described. Obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments. Based on the embodiment in the application, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the application's protection.

Being the ball head pin of auxiliary angle of rotation in a kind of numerical control shown in Fig. 1, be installed in insert, just again looking for after rotating for insert, described ball head pin comprises bulb, is positioned at the reference plane of described bulb lower surface, is positioned at the reference axis of described reference plane lower surface; The axle center of the centre of sphere of described bulb, the center of reference plane and reference axis is coaxially arranged.

As an embodiment of the present utility model, described bulb, reference plane and reference axis are formed in one structure.

As shown in Figure 2, in use, being arranged in the bottom outlet in insert by the reference axis 3 of ball head pin 4, the reference plane 2 of ball head pin 4 contacts with the heavy head bore bottom surface in insert. The sphere center position of bulb 1 in measure-ball pin 4, as the digital-to-analogue reference point after rotation.

This digital-to-analogue reference point effect is: establishes one between insert with insert after rotation before rotation and associates. Insert after rotation, needs when numerical control to pick up position accurately, in order to find position accurately, it is necessary to determine the X-direction of insert, Y-direction and a reference point; The X-direction of insert, Y-direction can continue to use X-direction, the Y-direction of insert before rotating, and the reference point reference point that just selection ball head pin 4 obtains. The utility model is used just again to look for, time saving and energy saving, assist angle of rotation by ball head pin 4, accurately simple and easy, satisfactory for result.

Claims

1. a numerical control is assisted the ball head pin of angle of rotation, it is characterised in that: comprise bulb, it be positioned at the reference plane of described bulb lower surface, be positioned at the reference axis of described reference plane lower surface; The axle center of the centre of sphere of described bulb, the center of reference plane and reference axis is coaxially arranged.

2. the ball head pin of auxiliary angle of rotation in numerical control as claimed in claim 1, it is characterised in that: described bulb, reference plane and reference axis are formed in one structure.
