Abstract
An internal and external diameter microcalipers comprises a U-shaped micrometer stand, a gage button equipped on the left of the micrometer stand, a micrometric screw equipped on the right of the micrometer stand and a data reading mechanism that form an external micrometer. The utility model is characterized in that a pair of internal diameter measuring paw heads are equipped correspondingly on the gage button and the micrometric screw of the external micrometer. The fixing paw head is fixedly connected with the gage button on the left and the moveable paw head is linked with the micrometric screw. A pair of paw heads of internal diameter measuring are added on the existing external micrometer. Thus the utility model has the function of measuring both internal and external diameter. The device is very convenient and the expenses of measuring apparatus equipment is reduced.
Description
Technical field:
The utility model relates to survey instrument.
Background technology:
In mechanical engineering, micrometer inside caliper and outside micrometer all are survey instruments that use always, indispensable.Milscale commonly used at present is divided into general milscale, outside micrometer, micrometer inside caliper and distortion milscale etc.Wherein, outside micrometer is mainly used in the outside diameter measuring of the axle class part in the certain limit, its formation mainly comprises: " U " shape chi frame, be fixedly installed on chi frame one end gage button, be slidingly arranged in micrometer spiral shell, the threaded sleeve of the chi frame other end, and reading mechanism, by micrometric screw and threaded sleeve as a pair of accurate screw male part, to return after axle motion changes rectilinear motion into, the reading mechanism of forming from fixed muffle and microdrum read length dimension.Micrometer inside caliper is mainly used in to be measured the internal diameter size of hole class, and it is a rod-like element that existing internal diameter do to divide a chi, during measurement, whole rod member is placed in the measured hole, with the length read of the bar internal diameter that portals.For a long time, failing will measure internal diameter all the time on milscale unifies with the function of measuring external diameter.Inconvenience is arranged in the use more.
Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology weak point, and a kind of interior outside micrometer that has inside and outside footpath measurement function concurrently is provided.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model by " U " shape chi frame, be located at chi frame left end gage button, be positioned at the micrometric screw of chi frame right part, and reading mechanism constitutes outside micrometer.
Architectural feature of the present utility model is that correspondence is provided with the inner diameter measurement pawl head that a pair of measurement faces outside survey on the gage button of described outside micrometer and micrometric screw, and wherein, fixed claw head and left side gage button connect firmly, moving jaws head and micrometric screw interlock.
The utility model is to increase a pair of inner diameter measurement pawl head is set on existing outside micrometer, thereby makes it have the function that inside and outside footpath is measured concurrently, can greatly make things convenient for use, and can reduce the expense that measuring appliance is equipped with.
Accompanying drawing is the utility model structural representation.
Number in the figure, 1 " U " shape chi frame, 2 gage buttons, 3 micrometric screws, 4 reading mechanisms, 5 fixed claw heads, 6 moving jaws heads, 7 shoulders, 8 interlock rings, 9 slide rails, 10 slide bars, 11 device for measuring force.
Embodiment:
Referring to accompanying drawing, adopt existing outside micrometer structure, by " U " shape chi frame 1, be located at chi frame 1 left end gage button 2, be positioned at the micrometric screw 3 of chi frame 1 right part, and reading mechanism 4 constitutes outside micrometers.
The outside micrometer structure is provided with routinely, reading mechanism 4 wherein is made up of fixed muffle and microdrum, and the left end of micrometric screw 3 is sounding rods, and the centre is the very high external thread of precision, with the internal thread precision-fit on the threaded sleeve, make external thread can be in internal thread rotation and the gap is minimum freely.The outer cone of the other end of micrometric screw 3 matches with the joint female cone, and connects with device for measuring force 11 by the internal thread on top, rotates together by device for measuring force 11 drive micrometric screws and microdrum, and two distances between the measurement face are changed.
In the present embodiment, different with prior art is on the gage button 2 of outside micrometer and micrometric screw 3 correspondingly is provided with the inner diameter measurement pawl head that a pair of measurement faces outside survey, and wherein, fixed claw head 5 connects firmly with left side gage button 2, moving jaws head 6 and micrometric screw 3 interlocks.
In order to realize the interlock between moving jaws head 6 and the micrometric screw 3, shown in the figure, at the slide rail 9 of the right part of " U " shape chi frame 1 setting with micrometric screw 3 parallel axes, the slide bar 10 that is slidingly matched is arranged in the slide rail 9, mobile melon head 6 is fixedly installed on the left part of slide bar 10, one shoulder 7 is arranged on slide bar 10, connect firmly the left side that interlock ring 8 on micrometric screw 3 is resisted against this shoulder 7.This structure is arranged so that micrometric screw 3 can be to the unidirectional drive of carrying out of moving jaws head 6, and promptly when measuring external diameter, moving jaws head 6 does not move thereupon.Only when measuring internal diameter, device for measuring force 11 drives micrometric screw 3, drive interlock ring 8 simultaneously, move to the right by being resisted against slide bar shoulder 7 first line of a couplet rotating rings 8 drive slide bars 10, thereby drive moving jaws head 6, make that distance changes between itself and the fixed claw head 5, on reading mechanism, carry out reading and can learn tested internal diameter.
In order to guarantee the measuring accuracy of internal diameter, in the present embodiment, the magnetic force that is set to adhesive mutually between the shoulder 7 of interlock ring 8 and slide bar 10 cooperates.In concrete the enforcement, interlock ring 8 can be set to magnetic.When measuring internal diameter, interlock ring 8 is pull-in on the shoulder 7, eliminates gap therebetween, thereby eliminates because the measuring error that exists the gap to bring.
