The invention discloses a drilling method for an inclined hole, and relates to the technical field of mechanical processing. An inclined hole drilling fixture is used and comprises a positioning shaft and a shaft sleeve which are arranged on a supporting plate, wherein a drilling sleeve fixedly arranged on the supporting plate by virtue of a connection plate is arranged above the positioning shaft, and the inclined angle formed between the center line of the shaft sleeve and the positioning shaft and the axis of the drilling sleeve is a; the shaft sleeve is provided with a limiting boss and two opposite arc-shaped plates, the shaft sleeve is internally provided with a pull rod in a penetrating manner, and the pull rod is provided with a conical surface; one end, which penetrates through the supporting plate, of the pull rod is provided with a locking nut, the positioning shaft is provided with a positioning boss and a positioning pin, the upper part of the positioning pin is provided with a groove, and the outer end of the positioning shaft is provided with a bolt and a press plate. The operation comprises the following steps: A, installing the fixture; B, installing a workpiece; C, drilling; D, discharging finished pieces. Compared with the prior art, the drilling method has the advantages that the inclined hole of a swing block is processed by virtue of the inclined hole drilling fixture, so that the operation of clamping the swing block is simple and convenient, and the production efficiency is high.
Description
Technical field
The present invention relates to technological equipment manufacturing technology field, especially a kind of boring method for processing the inclined hole angled with plane.
Background technology
Swinging block 10 as shown in Figure 1 and Figure 2, have two planes be arrangeding in parallel and with the large footpath through hole of two plane orthogonal and path through hole, the outside of large footpath through hole and path through hole is arc surface and the plane tangent with two arc surfaces, a plane tangent with two arc surfaces has oblique screwed hole, and the angle of the center line of this oblique screwed hole and the line of centres of large and small footpath through hole is 60 degree.Owing to not having special clamp for drilling slant hole, can only fix swinging block with pressing plate when processing the inclined hole of swinging block and hole, this boring method production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of boring method of inclined hole, to solve the problem of the inclined hole production efficiency of processing swinging block.
In order to solve the problem, the technical solution used in the present invention is: the boring method of this inclined hole, use a kind of inclined hole drill jig, this inclined hole drill jig includes dress locating shaft on the supporting plate and is positioned at the axle sleeve above described locating shaft, the drill bushing be fixed on by connecting plate in described gripper shoe is housed above described locating shaft, and the line of centres of described axle sleeve and described locating shaft and the angle of described drill bushing axial line are a; Described axle sleeve has positive stop lug boss and links be oppositely arranged two pieces of arcs of this positive stop lug boss outer end, pull bar is coated with in described axle sleeve, described pull bar is provided with and the taper seat crimped inside two pieces of described arcs, and locking nut is equipped with in one end that described pull bar passes described gripper shoe; Described locating shaft is provided with positioning boss and links the alignment pin of this positioning boss outer end, and the top of described alignment pin is provided with groove vertically, bolt is housed in the outer end of described locating shaft and is sleeved on the pressing plate on described bolt;
Operating procedure comprises:
A, sectional fixture: described inclined hole drill jig is arranged on Drilling machines bench;
B, installation workpiece: be enclosed within respectively by the large and small footpath through hole of swinging block on described alignment pin and two pieces of described arcs, described pull bar, through described axle sleeve, tightens described locking nut, loads onto described pressing plate and described bolt;
C, boring: start drilling machine, Drilling operation is carried out to described swinging block;
D, unload finished piece(s): after machining, pull down described pressing plate and described pull bar, take off the Drilling operation that namely described swinging block completes this swinging block.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention uses inclined hole drill jig to carry out processing the inclined hole of swinging block, and outwards opened by two pieces of arcs by the taper seat of pull bar, make the path through hole of swinging block and the axis centering of axle sleeve, clamping swinging block is simple and convenient, and production efficiency is high.
