Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of microscope zoom compensates microscope base drill jig.
Background technology
The mechanical compensation varifocal optical system that focal length continually varying stereomicroscope is used, generally has two motion constituent elements: Zoom lens constituent element and offset lens constituent element.When Zoom lens constituent element moves along optical axis, for guaranteeing stablizing of system image planes, offset lens constituent element moves along optical axis the most therewith.Zoom compensates microscope base and is used as supporting and the part of regulation offset lens constituent element, microscope zoom as shown in Figure 1 and Figure 2 compensates microscope base 6, include ring body 61 and from outward extending pin portion, ring body one end 62, ring body 61 centre bore 61a center and the line at pin pin-and-hole 62a center are angle a with the angle of vertical direction, offer two screwed holes 61f, 61g in the cambered surface end of ring body 61；Compensate microscope base in order to ensure zoom not change at the optical axis of offset lens constituent element along the moving process of systematic optical axis direction, therefore to the distance between these two screwed holes and perpendicularity and the precision in hole, it is desirable to precision is high；Otherwise can directly affect the image quality of whole optical system, owing to the line at the centre bore center of ring body 61 has angle with level, and irregular structure, therefore, processing is got up more difficult and loaded down with trivial details and machining accuracy does not the most often reach requirement, so being badly in need of a kind of simple and convenient and practical processing microscope zoom to compensate microscope base drill jig.
Summary of the invention
The technical problem to be solved is to provide a kind of microscope zoom and compensates microscope base drill jig, and this microscope zoom compensates microscope base drill jig can solve the problem that existing zoom compensates microscope base processing difficulties, precision is low and production efficiency is low.
nullIn order to solve the problems referred to above，The technical solution adopted in the present invention is: this microscope zoom compensates microscope base drill jig，Including the Workpiece clamping seat of annular and the workpiece model drilling body of arc that crosses out along this Workpiece clamping seat edge，Described Workpiece clamping seat one end is fixed with cylindrical Workpiece clamping core rod by work piece pressing plate，The described Workpiece clamping seat other end is fixed with mounting seat by lock-screw，Described mounting seat includes base and the circular slab being coaxially disposed with described Workpiece clamping seat，Workpiece slide opening is offered on described circular slab，The hole, location installing locating dowel is offered in described workpiece slide opening,Hole, described location includes the first hole, location and the second hole, location，Described first hole, location is angle a with the described line at Workpiece clamping seat center and the angle of vertical direction，Described second hole, location is angle b with the described line at Workpiece clamping seat center and the angle of vertical direction.
Above-mentioned microscope zoom compensates in microscope base drill jig technical scheme, more specifically technical scheme is it may also is that offer workpiece drill bushing along arc core direction in described workpiece model drilling body, described locating dowel is included in the interior trunk portion slided of described slide opening and the positioning round table in hole, described location inner position, the diameter of the described positioning round table width more than described slide opening, the diameter less than hole, described location, the width of described slide opening is connected with the spring being located in fixed cover by positioning round table less than the diameter in hole, described location, described trunk portion.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, being designed to compensate the workpiece model drilling body of the arc that microscope base matches with zoom according to its zoom compensating glass holder structure owing to microscope zoom compensates microscope base drill jig, clamped one time can be processed two holes, and reach required precision.
2, convenient mounting and clamping of the present invention, is suitable for producing in enormous quantities, has not only saved the production time and has also substantially increased production efficiency.
