Abstract
The utility model relates to an instrument movement and dial precision centring structural device which belongs to the technical field of metering test. The utility model is characterized in that a positioning bearing sleeve is arranged on the upper end of the upper splint of the original instrument movement, the positioning bearing sleeve is sheathed in a machine core column, a shoulder shield is arranged on the upper end of the positioning bearing sleeve to tightly match with a dial, the two sides of the positioning bearing sleeve are fixed with the upper splint by screws, so that the instrument movement and the dial are combined as integration. The precision of the instrument can not be affected by the separation or the movement of a casing and the instrument movement.
Description
The utility model belongs to gaging pressure in the metrology and measurement field or a kind of instrument of pressure-type thermometer, makes tensimeter reduce error on the indicating structure specifically, and has kind of the device of going up of high stability first finger.
The error that present employed tensimeter causes on indicating device is mainly inaccurate at indicating device design of part and fit on, specifically be reflected at the coaxiality error in the center of circle of cursor backward center and circular graduation line, generally by the adjustment personnel by range estimation and adjust repeatedly and control, be difficult to guarantee the tensimeter precision, meter movement and scale are separate type simultaneously, instrument is directly influenced by external force and causes indicating value to be drifted about, in case and shell is loosening, the capital makes the instrument misalignment, when the internal mechanism of whole instrument separates with watchcase or watchcase is taken off, then can't guarantee normally and exactly indication.
The purpose of this utility model provides a kind of external force of working as and directly interferes watchcase can not cause indicated value drift and instrument misalignment, and whole gauge internal mechanism separates with watchcase, inner structure is an integral body, can guarantee equally that normally and exactly a kind of meter movement of indication and scale precision are to the core structure device.
For finishing the technical scheme that above-mentioned purpose is taked: the train wheel bridge upper end at existing meter movement is provided with the locating shaft bearing sleeve, and is inserted in the movement post, lives the bearing holder (housing, cover) upper end surely and establishes shoulder first and scale wringing fit, lives the bearing holder (housing, cover) both sides surely and is fixed by screw and train wheel bridge.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation.
According to shown in Figure 1, fix by column 7 and by screw 6 at existing train wheel bridge 3 and lower plate 9, be provided with between the upper and lower clamping plate 3 and 9 on the meter movement base of sector gear 8 compositions, the upper end that it is characterized in that clamping plate 3 is provided with locating shaft bearing sleeve 1, and be inserted in movement post 2, shoulder first and scale 4 wringing fits are established in locating shaft bearing sleeve 1 upper end, locating shaft bearing sleeve 1 both sides are fixing with train wheel bridge 3 by screw 5, thereby finish movement and scale accurately to the heart, and making scale and movement is one, can not be subjected to separating or moving and influence instrument precision of watchcase and movement.
