The utility model discloses guarantee on the central voussoir by the position accuracy between two pinholes of processed with further having guaranteed the machining precision, to have simple structure, convenient to use, the machining precision is high, machining efficiency is high, the processing cost is low advantage.
Description
Technical field
The utility model relates to a kind of processing tool, especially relates to a kind of drilling tool of center wedge.
Background technology
Center wedge is a kind of cast member, center wedge needs process two pin-and-holes, and two pin-and-holes are positioned at two upper lateral parts of center wedge, and the status requirement between two pin-and-holes is: ensure two pin-and-hole coaxial lines.In prior art, when using conventional brace to be installed to center wedge, except non-used twin tip drill machine is processed the pin-and-hole of two in center wedge, otherwise be difficult to ensure the position relationship in center wedge between two pin-and-holes, but the use cost of double end rig is high, the processing that can increase center wedge drops into, and using two pin-and-holes of simple drilling tool respectively in center wedge to process, then the Product Precision processed is low, and working (machining) efficiency is not high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of drilling tool of center wedge.
The technical problem that the utility model further solves is to provide a kind of drilling tool of center wedge, comprises a support slot and a pressing plate; End face and the leading flank of described support slot are uncovered, and the top of the left and right wall of described support slot offers the boring be positioned on same central axis; The rear wall of described support slot is extended with two pieces of casting lug thereons forward, and the square hole of described casting lug thereon and center wedge coincide; Described pressing plate is fitted and is removably fixed on Zuo Bi and You Bi of described support slot before described support slot, and described pressing plate described support slot corresponding to the face that described support slot is fitted is provided with two pieces of casting lug thereons.
Relative to prior art, the drilling tool of a kind of center wedge of the utility model, position between this frock is holed for two of machining center voussoir pin-and-hole is through standard design, frock and simple drill with the use of, just the positional precision between two pin-and-holes processed in center wedge can be ensured, simultaneously the utility model fixedly utilizes center wedge square hole structure inherently to center wedge, from five faces, in addition stickiness is fixing, avoid the movement of center wedge in processing, further ensure machining accuracy, there is structure simple, easy to use, machining accuracy is high, working (machining) efficiency is high, the advantage that processing cost is low.
As the further improvement of the drilling tool of a kind of center wedge of the utility model, the rear wall top of described support slot turns forward, and its angle of inclination is consistent with the angle of inclination on center wedge trailing flank top; Described pressing plate top tilts backwards, and its angle of inclination is consistent with the angle of inclination on center wedge leading flank top.
As the further improvement of the drilling tool of a kind of center wedge of the utility model, in described boring, be provided with drill bushing.
According to a preferred embodiment of the present utility model, described pressing plate is fixedly connected with by screw with right wall with the Zuo Bi of described support slot.
The beneficial effects of the utility model are: the drilling tool of a kind of center wedge of the utility model, position between this frock is holed for two of machining center voussoir pin-and-hole is through standard design, frock and simple drill with the use of, just the positional precision between two pin-and-holes processed in center wedge can be ensured, simultaneously the utility model fixedly utilizes center wedge square hole structure inherently to center wedge, from five faces, in addition stickiness is fixing, avoid the movement of center wedge in processing, further ensure machining accuracy, there is structure simple, easy to use, machining accuracy is high, working (machining) efficiency is high, the advantage that processing cost is low.
Except technical problem, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model described above solves, the advantage that the other technologies feature comprised in the other technologies problem that the drilling tool of a kind of center wedge of the utility model can solve, technical scheme and these technical characteristics bring, will be described in further detail by reference to the accompanying drawings.
