Abstract

The utility model relates to a device for accurately positioning the central position of a wire cutting penetration hole, which is composed of a fixed mount, a shim plate, a threaded rod, a spring, a connecting rod, a central cone, etc., which are arranged on an upper screw rod of a wire cutting machine. The central cone can be stopped at the central position of a penetration hole by the proper process control movement of the wire cutting machine. The top part of the connecting rod can be struck by a hammer or a heavy article. The central cone can strike out a central pit on a work piece, and the central pit is the central position of the penetration hole. The central cone can be stopped at the central position of a next penetration hole according to the process movement. The position of each central hole can be exactly positioned by repeat.

Description

The device in the accurate centre of location of wire cutting machine hole

Technical field

The utility model belongs to wire cutting machine tool manufacture field

Background technology

Boring again that the endoporus of wire cutting machine processing parts and interior being pickled with grains or in wine all will have wire hole, and conventional method is setting-out---hitting heart hole---.But its site error is too big, often can not ensure the quality of products for aperture, narrow groove.It is too high to process this class wire hole cost with jig boring machine, and the cooperation of going out is also mistaken very much.

Summary of the invention

In order to process the high wire hole of precision, the utility model provides the device in the accurate centre of location of a kind of wire cutting machine hole, utilizes the program control motion of wire cutting machine itself to determine that central hole location just can deal with problems well.

The technical scheme that the utility model addresses the above problem is: a fixed mount is installed on the upper screw rod of wire cutting machine, and fastening by screw rod, insert connecting rod on the fixed mount, a center cone is installed in the connecting rod lower end.The centre coordinate position of each wire hole is weaved into the controller of numerical control program input wire cutting machine, under this programme-control, center cone stops in the center of each wire hole successively, impact the connecting rod top with Hammer head or weight, center cone can be got center hole on workpiece, thus determined each wire hole the center.

Advantage of the present utility model is to make full use of the program control motor function of wire cutting machine itself, mixes a centre bore positioner, can process the very high hole, center of positional precision on workpiece, simultaneously, the centre bore positioning device structure is simple, and processing cost is very low, uses also very convenient.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a basic example structure structural map of the present utility model.

Fig. 2 is another example structure structural map of the present utility model.

1. workpiece, 2. center cones, 3. screws, 4. connecting rods, 5. fixed mounts, 6. upper screw rods, 7. backing plates, 8. apertures, 9. Luo bars, 10. metallic cylinder, 11. guide posts among the figure

The specific embodiment

In Fig. 1,

1, workpiece (1) is fixed on the workbench of wire cutting machine,

2, the fixed mount (5) of centre bore positioner is installed in the upper screw rod (on 6) of wire cutting machine, and with Luo bar (9) and backing plate (7) with they firm connections,

3, input central hole location program,

4, every central hole location impacts the top of connecting rod (4) with Hammer head or weight, and center cone (2) can be got the hole, center on workpiece (1).

5, allow the centre bore positioner move to next central hole location again, the operation that repeated for the 4th step gets final product.

So repeatedly, can accurately determine the position of all centre bores, its positional precision can satisfy the line cutting processing requirement of aperture, narrow groove etc. fully.

In Fig. 2

Operation principle and Fig. 1 are basic identical.Only be that with Fig. 1 difference the connecting rod top has added a metal guide post (11), the guide post overcoat metallic cylinder (10) of a suitable weight, when needs hit heart hole, the metal ring that raises can fall along the metal guide post, rely on the gravity effect to get the hole, center, this is much more steady than impacting with the Hammer head.

Claims

1, the device in the accurate centre of location of a kind of wire cutting machine hole is characterized in that a fixed mount is installed on the upper screw rod of wire cutting machine, and is fastening by screw rod, inserts connecting rod on the fixed mount, and a center cone is installed in the connecting rod lower end.
