The tooling has the characteristics of simple structure, convenient installation and adjustment as well as high machining precision.
Description
Technical field
The utility model relates to a kind of machining frock, is specifically related to a kind of for the frock for boring one-piece camshaft end-face hole.
Background technology
Camshaft is divided into one-piece camshaft and separated cam shaft, and being with cogged camshaft is one-piece camshaft, and the camshaft with gear is not separated cam shaft.For one-piece camshaft, conventionally need on end face, process various holes for filling pressure reducing valve component or as timing points identification hole etc.
Existing camshaft end face drilling tool configurations, but ubiquity complex structure, install and regulate inconvenient, angle orientation benchmark to be difficult to determine to cause the not high series of problems of machining accuracy.
Utility model content
The purpose of this utility model is to provide a kind of frock being exclusively used in for boring one-piece camshaft end-face hole, have simple in structure, feature easy to adjust, machining accuracy is high is installed.
For this reason, what the utility model provided is a kind of for boring the frock of one-piece camshaft end-face hole, comprise base (1), and be installed in the column (2) on base (1), bushing plate (3) is equipped with in the upper end of described column (2), on described bushing plate (3), be embedded with drill bushing (12), it is characterized in that: also comprise top (4), lower top (5), location-plate (6), lower top fairlead (7), handle nut (8) and "T"-shaped seal washer (13), described location-plate (6) and lower top fairlead (7) are installed on column (2), and be arranged at interval in the upper and lower between bushing plate (3) and base (1), described top (4) are installed on bushing plate (3), in the blind hole of the lower end inserted base (1) of "T"-shaped seal washer (13) and be fixed on base (1), insert in the endoporus of "T"-shaped seal washer (13) through after the pilot hole of lower top fairlead (7) lower end of described lower top (5), described handle nut (8) is screwed together formation screw-nut body with lower top (5), and handle nut (8) is positioned between lower top fairlead (7) and "T"-shaped seal washer (13), the dead ahead of described location-plate (6) right-hand member is provided with the breach (6a) passing through for camshaft, before and after being also provided with axis, the right-hand member of location-plate (6) extends also the just location adjustment screw (9) to breach (6a)
Be preferably, described bushing plate (3), location-plate (6) are fixed on column (2) by bolt (10) respectively, it is upper that "T"-shaped seal washer (13) is fixed on base (1) by bolt (10), and described lower top fairlead (7) is sleeved on column (2) again by bolt (10) locking by connecting portion (7a).Be bolted, dismantle more convenient.
Using method, first rotary handle nut, drive lower top moving down, vacate behind enough spaces, then workpiece is put into frock, in the upper top locating hole that withstands on workpiece upper surface, the middle part of workpiece is positioned at the breach of location-plate, opposite spin handle nut again, drives in the lower top locating hole that is moved upward to workpiece lower surface, thereby workpiece is clamped in advance; Regulate again location expansion screw, the front end of locating expansion screw is against on the confined planes of camshaft setting, to determine the setting angle of camshaft, finally by handle nut, workpiece is locked again, just can pass drill bushing by drill bit afterwards camshaft end face is holed.Seal washer is set, prevents that the bits end producing in boring procedure from entering between lower top and handle nut, produce clamping stagnation, reduce the service life of part.
The beneficial effects of the utility model are: have simple in structure, feature easy to adjust, machining accuracy is high is installed.
