Description

High accuracy is milled and is bored multi-functional processing tool

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to a kind of positioner that bores multistage manufacturing processes that workpiece is milled.

Background technology

Blank 1 as shown in Figure 1, it contains a circular base plate 11 and with the cylinder boss 12 of locating hole, now need to be processed into finished parts 2 as shown in Figure 2, be square at finished parts shown in Figure 22, and bottom surface 21 is an arc surface, be distributed with inclined hole 22 on arc surface, and contain a counterbore 23.In traditional conventional machining mode, process finished parts shown in Figure 22, need first on milling machine the chassis 11 circumference facing cut squarelys of blank 1 are milled into the bottom surface on chassis 11 arc surface 21 of finished parts 2, and then to getting out inclined hole 22 on arc surface 21; Complete above operation, if use many cover frock clamps, will certainly affect production efficiency, improve processing cost, if but use machining center to process, the positioning tool that can realize milling, boring multistage manufacturing processes just must be arranged.

The utility model content

The utility model provides a kind of high accuracy to mill and bores multi-functional processing tool for above-mentioned shortcoming of the prior art, and it is simple in structure, and is economical and practical, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

High accuracy is milled and is bored multi-functional processing tool, comprises positioning disk and location-plate, on the plane of positioning disk with several locating holes; With First terrace and second step face, with the location counterbore, be provided with through hole in the bottom of counterbore on the second step face on location-plate; Location-plate is positioned on a distolateral wall of First terrace with several connecting holes;

Further technical scheme is as follows:

The quantity of the connecting hole on the locating hole on described positioning disk and location-plate is identical is 6;

Described First terrace is higher than the second step face;

Described positioning disk is connected the location with alignment pin by bolt with location-plate.

The utility model has the advantage of: positioning disk and location-plate are set, both are connected, man-hour positioning disk is clamped adding, drive location-plate and rotate; Process counterbore and through hole for the blank boss of location finished parts on location-plate, add man-hour when blank is milled, location-plate is in level, when carrying out Drilling operation, by the rotational positioning dish, make blank rotate required angle, carry out Drilling operation; The utility model is simple in structure, and is economical and practical, and machining accuracy is high.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

To shown in Figure 8, the utility model comprises positioning disk 3 and location-plate 4 as Fig. 1, and on the plane 31 of positioning disk 3, with several locating holes 32, locating hole 32 is used for being connected the location with location-plate 4; On location-plate 4 with First terrace 41 and second step face 42, step surface 41 is higher than step surface 42, and on second step face 42, with location counterbore 43, the external diameter of the cylinder boss 12 on the internal diameter of counterbore 43 and blank 1 is identical, be provided with through hole 44 in the bottom of counterbore 43, be used for fastening blank 1; Location-plate 4 is positioned on a distolateral wall of First terrace 41 with several connecting holes 45, is connected and fixed by bolt and alignment pin with locating hole 32 on positioning disk 3; The quantity of the connecting hole 45 on the locating hole 32 on positioning disk 3 and location-plate 4 is identical is 6, and positioning disk 3 is connected location by bolt with alignment pin with location-plate 4;

Using method of the present utility model is as follows:

The first step positions location-plate 4 and positioning disk 3 by alignment pin, then with bolt, that location-plate 4 and positioning disk 3 is fastening;

Second step is installed to positioning disk 3 on the scroll chuck of machining center, and guarantees that step surface 41 and step surface 42 levels on location-plate 4 make progress;

The 3rd step, the cylinder boss 12 on blank 1 is matched with counterbore 43 on step surface 42, then use screw from the counterbore 23 on the chassis 11 of blank 1, blank 1 to be fixed on location-plate 4, as shown in Figure 7;

In the 4th step, the circumference on the chassis 11 of blank 1 is milled squarely, then the bottom surface on chassis 11 is milled out arc surface 21, as shown in Figure 8;

The 5th step turned an angle positioning disk 4, and arc surface 21 is carried out Drilling operation, got out inclined hole 22, namely processed finished parts 2, as Fig. 2 and shown in Figure 8.

Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
