Description
Technical field
The utility model belongs to the process unit of machining, is specifically related to a kind of boring and attacks two-used clip.
Background technology
Some machine components need often to be designed with screwed hole due to function, thread mill drilling needs boring and tapping two operations, traditional processing technology is after being holed on boring grab by parts fixation, again by parts fixation tapping on tapping clamp, its weak point is that process needs multiple clamping, can produce deviations in clamping process, cause the tooth of screwed hole dark shallow on one side on one side, produce waste product, and process labour intensity is large, production efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of cost of providing is low, and make simple, easy to use, labour intensity is low, and two-used clip attacked by the brill that production efficiency is high.
The technical solution of the utility model is: riser is provided with pivoting support, pivoting support is provided with bearing pin installing hole one, bushing plate has the bearing pin installing hole two, the drill bushing installing hole that match with bearing pin installing hole one, the pivoting support of bushing plate on bearing pin and riser is hinged, bearing pin is plugged in bearing pin installing hole one, bearing pin installing hole two, and drill bushing is loaded on the drill bushing installing hole on bushing plate.
Described pivoting support is two, and bushing plate is between two pivoting supports.
Described bushing plate one end is provided with lug, and the lug of bushing plate is between two pivoting supports, and bearing pin installing hole two is positioned on the lug of bushing plate.
Described bearing pin is bearing pin with holes, bearing pin with holes is equipped with for limiting the split pin of bolt axle with holes to movement.
Described drill bushing and drill bushing installing hole are interference fit.
The lug width α of described bushing plate is less than spacing b between two pivoting supports.
Described bearing pin installing hole two center line is equal to the distance d2 of riser upper surface with the central axis of bearing pin installing hole one to the distance d1 of bushing plate lower surface.
Bushing plate is coordinated by bearing pin with holes with riser, and be convertible bascule, riser is fixed, and bushing plate can rotate 180 ° by strip winding hole bearing pin.After clamping part, bushing plate is positioned at initial position, completes drilling operating, overturn drill template, then completes tapping procedures.Compared with other technologies, the utility model uses a sleeve clamp to complete two procedures, only needs clamping once, ensure that tapping can accurately be located, improves efficiency; This utility model structure simple, easy to operate, with low cost and be easy to safeguard, be suitable for widely.

Detailed description of the invention
In Fig. 1, the utility model comprises bushing plate (5) and is loaded on the drill bushing (3) of bushing plate (5), bushing plate (5) there is bushing plate lug (4), bushing plate lug (4) to be coordinated with two pivoting supports (6) on riser (7) by bearing pin with holes (1) and forms turnover movable device, bearing pin with holes (1) is equipped with split pin (2), limits bearing pin with holes (1) and move axially.
In Fig. 2,3, bushing plate (5) has drill bushing installing hole (10), for installing drill bushing (3), the central axis in hole one (10) and the central axes of hole to be processed (13), to ensure to lead accurately after drill bushing (3) is installed; Bushing plate (5) comprises bushing plate lug (4), and the width of bushing plate lug (4) is α, bushing plate lug (4) has bearing pin installing hole two (8), and bearing pin installing hole two (8) center line is d1 to the distance of bushing plate lower surface (9).
In Fig. 4, riser (7) there are two pivoting supports (6), distance between two pivoting supports (6) is b, a bearing pin installing hole one (11) is had in each pivoting support (6), the central axes of two bearing pin installing holes one (11), the central axis of bearing pin installing hole one (11) is d2 to the distance of riser upper surface (12).
In Fig. 5, bushing plate lug (4) is loaded between two pivoting supports (6), and width a and the spacing b of two pivoting supports (6) of bushing plate lug (4) are that small―gap suture coordinates, and moves left and right for limiting bushing plate (5); Bearing pin with holes (1) is through bearing pin installing hole two (8) and bearing pin installing hole one (11), and after installing, bushing plate lower surface (9) overlaps with riser upper surface (12), ensures bushing plate (5) above-below direction accurate positioning; Bearing pin with holes (1) is equipped with split pin (2), prevents bearing pin with holes (1) from deviating from from bearing pin installing hole two (8) and bearing pin installing hole one (11).
In Fig. 6,7, drill bushing (3) is loaded on the drill bushing installing hole (10) on bushing plate (5), drill bushing (3) and drill bushing installing hole (10) interference fit, drilling operating by bushing plate upset as shown in the figure, bearing pin installing hole two (8) center line is equal to the distance d2 of riser upper surface (12) with the central axis of bearing pin installing hole one (11) to the distance d1 of bushing plate lower surface (9), ensure that bushing plate (5) is in level, the central axis of drill bushing (3) and the central axes (as Fig. 6) of hole to be processed (13).In tapping procedures process (as Fig. 7), for making screw tap avoid bushing plate, bushing plate (5) upset 180 °, can process hole to be processed (13).Wherein, (7) are riser.
