Description

A kind of positional punch device of shaped piece circular hole position

Technical field

The utility model is related to a kind of positional punch devices, more particularly to a kind of positional punch of shaped piece circular hole position Device.

Background technology

When at present in machine-building production industry for being punched on the workpiece of special-shaped workpiece round hole hole position, for can not dosage The position for having size setting-out positioning measured directly, measurer can only be affiliated to other auxiliary items and carries out range estimation setting-out, makes its picture Line error is big, and positioning is inaccurate, and setting-out working hour is long, and it is low to make product quality.Processing cost can carry if being processed with numerically-controlled machine tool Height, and manually it will cause the low of production efficiency and product quality for setting-out.

Utility model content

The purpose of this utility model is the problem of being difficult to ensure for the round positional punch precision of current abnormity, it is proposed that one The positional punch device of kind shaped piece circular hole position, the position that quickly and accurately positional punch may be implemented using the present apparatus is subtracted Measurement setting-out error is lacked, has saved detection time, save labour turnover, has solved while can not ensure setting-out precision, improve Working efficiency and product quality, save manpower and time.

To achieve the above object, the utility model provides a kind of positional punch device of shaped piece circular hole position, described Positional punch device includes disc for die identical with step cutting pattern bore dia on shaped piece, the disc for die and the abnormity Step cutting pattern hole uses hole base system of fits, the disc for die to match using basic hole system with step cutting pattern hole on the shaped piece on part It closes, the marginal position of the disc for die is equipped with 360 ° of angle index line, and the disc for die center is equipped with handle Hand, the disc for die are equipped with location hole.

Preferably, the disc for die is made of sheet metal.

Based on the above-mentioned technical proposal, the utility model has the advantages that：

The positional punch device of the shaped piece circular hole position of the utility model can fast implement on special-shaped workpiece circular hole Be accurately positioned, surveyed and drawn without the position dimension for carrying out surface on special-shaped workpiece, reduce can not setting-out or setting-out it is difficult and lead The precision of cause is difficult to ensure problem, is conducive to improve working efficiency and product quality.

Description of the drawings

Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application, The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model It limits.In the accompanying drawings：

Fig. 1 is positional punch apparatus structure schematic diagram；

Fig. 2 is positional punch device schematic side view；

Fig. 3 is positional punch device operating diagram.

Specific implementation mode

Below by drawings and examples, the technical solution of the utility model is described in further detail.

The utility model provides a kind of positional punch device of shaped piece circular hole position, may be implemented soon using the present apparatus Speed, the position that punching is precisely located, which reduce, measures setting-out error, saves detection time, saves labour turnover, solve nothing It while method ensures setting-out precision, improves work efficiency and product quality, saves manpower and time.As shown in FIG. 1 to 3, A kind of preferred embodiment of the utility model is shown.

As shown in Figure 1 and Figure 2, the positional punch device includes mold identical with step cutting pattern bore dia on shaped piece Disk 2, step cutting pattern hole uses hole base system of fits on the disc for die 2 and the shaped piece, the disc for die 2 with it is described Step cutting pattern hole uses hole base system of fits, the marginal position of the disc for die 2 to be equipped with 360 ° of angle index on shaped piece Line 3,2 center of the disc for die are equipped with handle 5, and the disc for die 2 is equipped with location hole 4.

The present apparatus is made of disc for die, location hole, dial, four part of handle.The disc for die of the utility model is A disk of a diameter identical (basic hole system) is made according to step cutting pattern hole machined on special-shaped workpiece, scale is put in top, It requires to drill out location hole or centre bore on this disk according to the hole position on drawing, handle is fixed on disc centre.

Preferably, the disc for die 2 is made of the higher sheet metal of the mechanical performances such as tensile strength, yield strength. The disc for die 2 uses hole base system of fits with step cutting pattern hole on the shaped piece, to adapt to the round platform in special-shaped workpiece Rank hole.The angle index line 3 is used to refer to angle positioning, and the location hole 4 is determining that hole position, handle 1 are used for rotating pair Angle and pick and place mold.

As shown in figure 3, the positional punch device of the shaped piece circular hole position of the utility model can refer to following steps progress Punching：

Two mother rib lateral rotundums in step cutting pattern hole are done on special-shaped workpiece, front or the back side is not square in step cutting pattern hole Just in the case of setting-out, with square on the outside end face of great circle, a center line perpendicular to great circle is drawn, by the positioning Perforating device is put into circular hole, 0 of angle index line alignment perpendicular to the center line of great circle, with the location hole on mold To position the centre bit in the hole on special-shaped workpiece.It such as needs to divide equally on the same circumference and punch, need several holes as long as calculating Angle can get the centre bit in each hole accordingly carrying out each angle to it.Using positional punch device large quantities of The setting-out time can be saved in amount production, is improved product quality and production efficiency.

If punching is few on this kind of workpiece in production, the angle index line in disc for die can be only arranged to an instruction Label, the centre bore to be punched is got on disc for die, as long as the cue mark scale and work on disc for die when use Scale alignment punching on part, the workpiece centre bore to be punched can transfer to next procedure to be produced later.

Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than limits it System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model In range.
