Embodiment
In Fig. 1-Fig. 5, this a kind of inner diameter measurement milscale main part comprises: two parallel micrometer inside calipers of combining in front and back, fixedly elbow test aircraft, mobile elbow test aircraft, mobile elbow measuring staff, location round head screw and round end positioning and locking screw rod.
As follows with upper-part interconnected relationship and the kind of drive:
When gauger's turn microdrum (2) or dynamometry knob (1), micrometric screw (18) under the spacing drive of micrometric screw round end dog screw sphere (24), promote mobile elbow measuring staff (17) do before and after slippage, micrometric screw round end dog screw sphere (24) and micrometric screw round end dog screw periphery (23) limit the gap that is slidingly matched of itself and micrometric screw (18); The mode that micrometric screw (18) promotes forward is that micrometric screw locating slot (8) and the micrometric screw round end dog screw (19) of forward end drives; Mobile elbow measuring staff (17) in the slipping of front and back its axial location and bearing accuracy radially by measuring staff slideway round end positioning screw (5) and round end positioning and locking screw rod (33) and (36) control.Micrometric screw (18) is identical with the structure of outside micrometer with the drive mechanism of microdrum (2), and the ratchet helical teeth direction of dynamometry knob (1) the inside is opposite with outside micrometer, and Principle and method of measurement is identical with outside micrometer.
The feature of this a kind of inner diameter measurement milscale, structure and embodiment are as follows:
This a kind of inner diameter measurement milscale forms by two micrometer inside calipers (S1) with (S2), and two micrometer inside calipers detect respectively maximal value Dmax and the minimum value Dmin of workpiece diameter dimension limit; Two micrometer inside calipers adopt the design of elbow gauge rods, and fixedly elbow measuring staff and mobile elbow measuring staff realize that four gauge heads are to the detection of workpiece diameter dimension limit with two pairs.
Before testing begins, at first cooperate elbow gauge head adjusting knob (11,28) and elbow test aircraft adjusting screw(rod) (14) that elbow gauge head (9,10,31,32) is adjusted to the reference position value by the fixedly elbow test aircraft setting nut (12,13,29,30) on the blade (7), " 0 " line and fixed cover scale mark (4) measurement start line on the microdrum scale mark (3) are aligned.When detecting workpiece, at first according to the numerical value position that respectively be adjusted to required detection of two values (being maximal value Dmax and minimum value Dmin) that are detected workpiece diameter dimension limit with two micrometer inside calipers, then round end positioning and locking screw rod is locked, it is right directly to transfer according to scale datum line above the fixed cover (34,35) during logarithm value, and convenient survey the when the scale datum line (22) in fixed cover front is mainly used to process the internal diameter size measurement read.
When testing begins, when among the minimum value Dmin that the internal diameter of measured workpiece has been put into this internal diameter check milscale S2, illustrate that the minimum limit value of this workpiece diameter size meets the requirements, otherwise, then undesirable; When the internal diameter of measured workpiece is put to advance among the maximal value Dmax of this internal diameter check milscale S1, illustrate that the maximum limit of this workpiece diameter size meets the requirements, otherwise, then undesirable; That is to say, the internal diameter of measured workpiece has been put among the minimum value Dmin of this inner diameter measurement milscale S2, and puts to advance among the maximal value Dmax of this inner diameter measurement milscale S1, illustrates that just the internal diameter dimension limit of this measured workpiece meets the requirements.In like manner, if when the internal diameter of this measured workpiece is put to advance among the minimum value Dmin of this inner diameter measurement milscale S2, the least limit deviate Dmin overproof (namely too small) of this measured workpiece internal diameter is described; If the internal diameter of this measured workpiece has been put among the maximal value Dmax of this inner diameter measurement milscale S1, the greatest limit deviate Dmax overproof (namely excessive) of this measured workpiece internal diameter is described.Adopt the internal diameter dimension limit that this inner diameter measurement milscale not only can convenient, fast and accurate detection workpiece, simultaneously can also detect overproof scope, in order to tell certified products, reprocessed products (if the internal diameter minimum limit of size of measured workpiece is too small, can take according to circumstances special processing process to carry out secondary processing, the internal diameter minimum limit of size is met the requirements) and waste product.
This inner diameter measurement milscale is compared with traditional inner diameter measurement measurer and detection method, design ingenious, easy and simple to handle, detect accurately, can save operator's detection time, improve detection efficiency, be the novel product of inner diameter measurement detection field, the progress of machining being measured technique will have positive impetus.
