Technical field
The invention belongs to the process unit of machining, be specifically related to a kind of drilling-hole positioning device.
Background technology
Some machine components are used for connecting hose because the needs of function are often designed with only hole boss at certain position, and boss cylindrical is made up of anti-slip part and hermetic unit.Boss oral area makes the similar hemispheric annular projection in a bit of cross section, and in order to block rubber tube with anti-slip, it is cylindrical as sealing surface that a long section is made at other positions of boss, and boss middle processes a cylindrical straight hole for ventilation or water flowing.Conventional machining process is located with the Position with One Plane and Two Holes of part, then arrange drill bushing at theoretical position place, only hole, and drill bit is holed under the guiding of drill bushing.Because the uniformity of blank is poor, the center, hole that part processes, often not at the center of boss, is caused the partially thin or hole wall of hole wall to penetrate, is produced a large amount of waste product.
Summary of the invention
The object of the invention is to the deficiency for existing processing technology and provide a kind of accurate positioning, easy to adjust, make simple drilling-hole positioning device.
Technical scheme of the present invention is: comprise bushing plate, be loaded on locating piece below bushing plate; Described bushing plate is provided with a step through-hole, and step through-hole comprises and is positioned at bottom for holding the large stepped hole of part upper end to be processed jut and superposed small stair hole, and the small stair portion of step drill bushing is plugged in the small stair hole of bushing plate; Locating piece is provided with corresponding with bushing plate step through-hole, to clamp part to be processed locating hole, and the tie down screw for locking part to be processed is equipped with in locating piece side.
Described locating piece side has the screwed hole connected with locating hole, and tie down screw is loaded on screwed hole.
Described locating hole is made up of V-arrangement section holes and rectangle cross-shaped holes, and drill bushing center line is equal with the radius of part cylindrical portion to be processed to the distance of V-arrangement section holes inwall two plane.
Described bushing plate is loaded on locating piece through screw, straight pin.
Locating hole cross section forms with the two sections being approximately square-section by being approximately V-arrangement cross section.Part only hole boss periphery is close in V-arrangement face makes only hole boss be able to accurate location, and tie down screw is by the screwed hole Clamp blocks of opposite side.Drill bushing is loaded in bushing plate small stair hole, and bushing plate and locating piece are located by straight pin, guarantees boss center, drill bushing center alignment element only hole.Together with bushing plate is connected by screw with locating piece.Tie down screw is welded by screw rod and moving rod.Compared with other technologies, accurate positioning of the present invention, structure is simple, easy to adjust, with low cost and easily safeguard, is suitable for widely.

Detailed description of the invention
In Fig. 1, the present invention includes bushing plate 1, be loaded on locating piece 11 below bushing plate 1, bushing plate 1 is provided with a step through-hole, and the small stair portion of step drill bushing 13 is plugged in the small stair hole 2 of bushing plate 1; Locating piece 11 is provided with locating hole 12 that is corresponding with bushing plate 1 step through-hole, that clamp part to be processed, and the tie down screw 10 for locking part to be processed is equipped with in locating piece 11 side.Only hole boss 5 of part 8 to be processed comprises several parts such as cylindrical portion 9, annular projection 4, cylindrical straight hole 6, only hole boss 5 own centre line 7.Locating hole 12 is made up of V-arrangement section holes and rectangle cross-shaped holes.Drill bushing center line 15 is equal with the radius of part cylindrical portion 9 to be processed to the distance of V-arrangement section holes inwall two plane.Boss center, part behind location only hole overlaps substantially with drill bushing endoporus 14 center.
In Fig. 2,3, bushing plate 1 and locating piece 11 are located by straight pin 18, are connected by screw 16.Bushing plate 1 is shaped with the location of cylinder pin hole 19 for straight pin 18, is shaped with the connection of stepped hole 17 for screw 16.Locating piece 11 is shaped with the screw hole 20 corresponding with stepped hole 17.
In Fig. 4, part 8 to be processed solely boss upper end, hole annular projection stretches in the large stepped hole of bushing plate, is stuck in V-arrangement section holes, offsets bottom tie down screw 10 with part outer wall to be processed.11 is locating piece.
In Fig. 5,6, locating piece 11 side has the screwed hole 23 connected with locating hole 12, and tie down screw 10 is loaded on screwed hole 23.Locating piece 11 is shaped with locating hole 12, two cylinder pin hole, two screw holes that are made up of V-arrangement section holes 21 and rectangle cross-shaped holes 22.V-arrangement section holes inwall two plane is V-arrangement section holes inwall plane 1, V-arrangement section holes inwall plane 2 25.
