Abstract
A method for machining holes on a workpiece includes such steps as locating a workpiece on a template set consisting of a template with small correcting-locating holes and another template with big ones, clamping the workpiece, fixing the template set onto platform, drilling from the small correcting-locating hole to big one, drilling reversely, broaching from big hole to small hole, and reaming from big hole to small hole.
Description
[technical field]
The present invention relates to a kind of machining process, especially a kind of cutting working method of hole.
[background technology]
Punch on workpiece at present, normally workpiece is directly placed on (location, clamping) processing platform and carry out drilling processing, concrete operations are subdrilling one aperture normally, again this aperture is carried out reaming, obtains requiring the hole of dimensions.This traditional drilling processing method, in drilling process, be difficult to avoid the distortion and the skew of drill bit, therefore when beginning subdrilling aperture, just can cause this little bore deformation (as bending) and increased in size and morpheme error, exceed the scope of its dimensional tolerance and form and position tolerance; And when reaming, this aperture has the effect to the drill bit guiding, therefore is difficult to correct by reaming.Especially the strict hole of relation, a plurality of position is processed in drilling on a workpiece, and when drilling processes the hole with identical dimensional tolerance and form and position tolerance on a plurality of workpiece, therefore this traditional drilling processing method more is difficult to reach machining accuracy owing to need repeatedly location and clamping work pieces.
[summary of the invention]
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome existing workpiece directly to be placed the deficiency of the existing large-size of drilling machining hole and morpheme error on the processing platform, and a kind of cutting working method of new hole is provided.For this reason, the present invention takes following technical proposals:
A kind of cutting working method of hole, it is characterized in that the workpiece location, be clamped on the mould, make workpiece corresponding with the concentricity large and small orthopedic locating hole of the row of two on mould two templates that is divided into, mould is placed on the processing platform, punch to big orthopedic locating hole direction from little orthopedic locating hole earlier with drill bit, again from big orthopedic locating hole to the reaming of little orthopedic locating hole direction, to little orthopedic locating hole direction fraising fine finishining is carried out in the hole on the workpiece from big orthopedic locating hole with reamer at last.With this method machining hole on workpiece, can aim at the position of punching by large and small orthopedic locating hole, and can correct drill bit and reamer, prevent distortion and the skew in the punching process of drill bit and reamer, reduce the size and the morpheme error in hole, guarantee that it reaches higher processing precision.
The cutting working method in described hole is characterized in that supporting positioning splint between described two templates, and corresponding workpiece location division is set on positioning splint.
The cutting working method in described hole is characterized in that in the end of workpiece Positioning Gear being installed.Prevent the rotation of workpiece in the process.
The cutting working method in described hole is characterized in that locating simultaneously, clamps a plurality of workpiece on mould, the concentricity large and small orthopedic locating hole corresponding with each workpiece is set respectively on two templates.The hole that processes on workpiece like this has good correspondence.
The cutting working method in described hole is characterized in that described punching and reaming finish through 1-3 time.
The existing relatively processing method of the present invention, be with the workpiece location, be clamped on the mould, aim at the position of punching by the large and small orthopedic locating hole on the mould, and correct drill bit and reamer, prevent distortion and the skew in the punching process of drill bit and reamer, reduce the size and the morpheme error in hole, guarantee that it reaches higher processing precision.
[description of drawings]
Fig. 1 is the structural representation of related mould in the inventive method.
Fig. 2 is the schematic diagram with the inventive method machining hole.
[specific embodiment]
Mould shown in Figure 1, comprise A template, B template and two support positioning splint C, wherein offer the parallel little orthopedic locating hole A1 of two row on the A template, offer two row and the big one to one orthopedic locating hole B1 of little orthopedic locating hole on the B template, the two ends of A template, B template also offer supported hole A2, B2; Two are supported the workpiece location division C1 that then offers two correspondences on the positioning splint respectively, two are supported positioning splint and are plugged in the supported hole, thereby guarantee the position corresponding relation of A, two templates of B, make the large and small orthopedic locating hole correspondence on it, realize that the dismounting of A, two templates of B connects.
As shown in Figure 2, earlier two workpiece E are installed in two workpiece location divisions of supporting on the positioning splint C, and intermeshing Positioning Gear are installed at the same end of two workpiece; Support positioning splint with two afterwards and be plugged in the supported hole of A, two templates of B, adjust the position of workpiece, make the position of preprocessing hole on the workpiece corresponding with large and small orthopedic locating hole A1, the B1 of A, two templates of B; Use clamping device (as to be connected A at last, screw rod between two templates of B, not shown in the figures) with A, two templates of B are fixed together, use again location structure (as be arranged on the mould can adjusting position the tooth bar that is meshed with this gear, not shown in the figures) Positioning Gear is fixed, the mould that will have workpiece at last places on the processing platform, punch to big orthopedic locating hole direction from little orthopedic locating hole earlier with drill bit, again from big orthopedic locating hole to the reaming of little orthopedic locating hole direction, to little orthopedic locating hole direction fraising fine finishining is carried out in the hole on the workpiece from big orthopedic locating hole with reamer at last.In this process, orthopedic locating hole is corrected drill bit and reamer, has limited the two distortion and skew, thereby can reduce the size and the morpheme error in hole, guarantees that it reaches higher processing precision.
The mode that positions by the gear mesh workpiece in the above-mentioned method can also get out a locating hole earlier with drill bit on arbitrary workpiece, and inserts the replacement of alignment pin (not shown) in this locating hole.And this method of the Positioning Gear that is meshing with each other being installed at the same end of two workpiece is convenient to make two workpiece to turn an angle simultaneously, thereby processes corresponding hole (this is especially crucial when paired workpiece symmetry work) thereon.
Need to prove, shown in Figure 2 is an object lesson of machining hole on two workpiece, under the prompting of this example, single or multiple workpiece are processed, and on each workpiece, process what holes, all can under the prerequisite of the large and small orthopedic locating hole that has mutual correspondence on two templates that guarantee mould, change the actual specification of mould according to actual needs.
