Abstract
The invention relates to a locating fixture for drilling of the excircle of a circular barrel. The locating fixture comprises a locating shaft, wherein the locating shaft is divided into a clamping section and a locating section, a shoulder is arranged between the clamping section and the locating section, a die hole is formed in the excircle of the locating section, a thread hole is formed in the end surface of the locating section, and a locating plate is fixedly connected by a screw nail via the thread hole; and the locating section and the inner hole of a workpiece form interference fit. The locating fixture disclosed by the invention is simple in structure, simple and convenient to operate, and high in locating machining accuracy.
Description
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to the positioner of Drilling operation on the cylinder cylindrical.
Background technology
Workpiece to cylinder type adds man-hour, in order to guarantee the machining accuracy of workpiece, not only needs it is carried out axial location, also must carry out radial location simultaneously; When the cylindrical to a cylindrical workpiece carried out Drilling operation, especially thinner to barrel workpiece in order to reduce the distortion of workpiece in the process, must adopt certain measure can guarantee that the precision of holing can reduce again the distortion of workpiece.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, a kind of cylinder cylindrical hole drilling positioning fixture is provided, it is simple in structure, and is easy and simple to handle, and the location machining accuracy is high.
The technical solution adopted in the present invention is as follows:
Cylinder cylindrical hole drilling positioning fixture comprises locating shaft, and locating shaft is divided into gripping section and positioning section, be provided with convex shoulder between gripping section and the positioning section, with nib, be threaded the hole on the end face of positioning section on the cylindrical of positioning section, be fixed with location-plate by screwed hole with screw; The endoporus of positioning section and workpiece is interference fit.
The invention has the advantages that: at locating shaft convex shoulder and positioning section are set, and process nib on the positioning section, can process Workpiece boring; On the end face of positioning section location-plate is installed, can be realized the axial location to workpiece, make simultaneously positioning section and workpiece interference fit, realize the accurate location to workpiece; The present invention is simple in structure, and is easy and simple to handle, and the location machining accuracy is high.
Description of drawings
Fig. 1 is the stereogram of locating shaft of the present invention.
Fig. 2 is use state diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the present invention includes locating shaft 1, locating shaft 1 is divided into gripping section 11 and positioning section 13, and gripping section 11 can be used for locating shaft 1 is navigated on the equipment; Be provided with convex shoulder 12 between gripping section 11 and the positioning section 13, on the cylindrical of positioning section 13 with nib 15, process locating hole 41 take nib 15 as benchmark at the cylindrical of workpiece 4, be threaded hole 14 on the end face of positioning section 13, be fixed with location-plate 2 by screwed hole 14 usefulness screws 3, location-plate 2 can clamp the two ends of workpiece 4 with convex shoulder 12, plays the axial location to workpiece 4; Positioning section 13 is interference fit with the endoporus of workpiece 4, can prevent in the process, and workpiece 4 occurs mutually to rotate with positioning section 13, guarantees the machining accuracy of locating hole 41 on the workpiece 4.
More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
