Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
The structural representation holding the examples of implementation of nog plate drilling equipment that Fig. 3 provides for the utility model.As shown in Figure 3, what the utility model provided hold nog plate drilling equipment comprises the first bushing plate 4, second bushing plate 5, needs are holed hold nog plate 1 by gripping means grips between the first bushing plate 4 and the second bushing plate 5, first bushing plate 4 and the second bushing plate 5 are provided with the drill bushing hole that the hole that nog plate 1 needs bore with holding of needing to hole is corresponding, clamping device comprises bolt and pin, and the first bushing plate 4 is fixed with leg 403.
Fig. 4-1 is the structural representation of the first bushing plate, and Fig. 4-2 is the top view of the structural representation of the first bushing plate, and the concrete structure of the first bushing plate 4 is as follows:
First bushing plate 4 comprises the first drill bushing hole 402, drill bushing hole 401, second, leg 403, first support plate 404 forms.
Supporting each three of the drill bushing in first drill bushing hole 401 and the second drill bushing hole 402, makes by high-abrasive material, rises lead effect of contraction to drill bit.
Turn-over supporting when leg 403 is convenient to hole, prevents from damaging pin.For guaranteeing that boring is correct, the second bushing plate 5 surface level when leg 403 should ensure to hole turn-over.
First support plate 404 is processed with two bolts hole 405, during assembling, wears bolt.First support plate 404 is also processed with a pin-and-hole 406, during assembling, wears pin 7.
Each 3 of the first drill bushing hole 402, drill bushing hole 401, second of processing on the first support plate 404, for assembling first bushing plate 4 and the second bushing plate 5.
Fig. 5-1 is the structural representation of the second bushing plate, and Fig. 5-2 is the top view of the structural representation of the second bushing plate, and the concrete structure of the second bushing plate 5 is as follows: the second bushing plate 5 comprises the 3rd drill bushing hole 501, second support plate 502.As Fig. 5-1 and Fig. 5-2, and the 3rd drill bushing hole 501 drill bushing is made up of high-abrasive material, rises lead effect of contraction to drill bit.
Support plate 502 is processed with three holes, for assembling drill bushing.
Support plate 502 is processed with two screws (503 in Fig. 5-1), for erection bolt.
Support plate 502 is processed with a pin (in Fig. 5-1 and 5-2 504) hole, for assembling pin.
On first support plate 404 and the second support plate 502, brill is joined in each hole.
Bolt, packing ring, pin are standard component, bolt and fastening first bushing plate 4 and the second bushing plate 5 of packing ring.Pin plays the role of positioning, and guarantees that counterbore is concentric.
Between bolt and the first bushing plate 4, packing ring 6 is installed.
What Fig. 6 provided for the utility model holds nog plate drilling equipment structural representation in use.Concrete installation process is as follows:
(1), as Fig. 3, by bolt, packing ring, pin, by the first bushing plate 4, nog plate 1 is held and the second bushing plate 5 assembles;
(2), leg upward, bore the bottom outlet of three screws;
(3), more bit change 8, bore the through hole of three counterbores;
(4), as Fig. 6, turn-over, leg, is replaced by 90 ° of taper countersinks down, processes three counterbores.
(5), dismantle drill jig, remove drilling cuttings, burr, machine.
In order to solve the deficiency of conventional method, adopt this device can lead to drill bit, limit bit deflection, thus ensure that hole is round, hole center line is parallel to and holds nog plate axis.
The utility model clamped one time, machining is porose, can ensure position and concentricity, ensures that drill bit will make the hole got out in oval by secundly.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
