Embodiment
In Fig. 1-Fig. 5, this a kind of digital display internal diameter detects the milscale main part and comprises: the micrometer inside caliper that parallel-group lumps together before and after two, fixedly elbow is surveyed frame, moves elbow survey frame, is moved elbow measuring staff, location round head screw and round end positioning and locking screw rod.
Following with the 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 to move 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 the micrometric screw locating slot (8) and the micrometric screw round end dog screw (19) of forward end drives; Moving elbow measuring staff (17) its axial location and bearing accuracy radially in the slipping of front and back is controlled by measuring staff slideway round end positioning screw (5) and round end positioning and locking screw rod (33) and (36).Micrometric screw (18) is identical with the structure of outside micrometer with the drive mechanism of microdrum (2), and the ratchet helical teeth direction and the outside micrometer of dynamometry knob (1) the inside are opposite, and measuring principle is identical with outside micrometer with method.
Characteristic, structure and embodiment that this a kind of digital display internal diameter detects milscale are following:
This a kind of digital display internal diameter detects milscale to be formed by two micrometer inside calipers (S1) with (S2), and two micrometer inside calipers show maximal value Dmax and the minimum value Dmin that detects workpiece diameter dimension limit respectively; Two micrometer inside calipers adopt the design of elbow gauge rods, and fixedly elbow measuring staff and mobile elbow measuring staff are realized the detection of four gauge heads to workpiece diameter dimension limit with two pairs.
Before testing begins; At first surveying frame setting nut (12,13,29,30) through the fixedly elbow on the blade (7) cooperates elbow gauge head adjusting knob (11,28) and elbow survey frame adjusting screw(rod) (14) that elbow gauge head (9,10,31,32) is adjusted to the reference position value; " 0 " line and fixed cover scale mark (4) measurement start line on the microdrum scale mark (3) are aligned; Numerical value in the display screen (39) in the digital display device is identical with the numerical value of check and correction simultaneously; When detecting workpiece; At first according to two values (being maximal value Dmax and minimum value Dmin) of workpiece diameter dimension limit to be detected numerical value position that is adjusted to required detection respectively with two micrometer inside calipers; With the locking of round end positioning and locking screw rod, it is right directly to transfer according to scale datum line above the fixed cover (34,35) during logarithm value then, and convenient survey the when the positive scale datum line (22) of fixed cover mainly is used for processing the internal diameter size measurement read.
When testing begins, when among the minimum value Dmin that has put the internal diameter of measured workpiece into this internal diameter check milscale S2, explain 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, explain that the maximum limit of this workpiece diameter size meets the requirements, otherwise, then undesirable; That is to say that the internal diameter of measured workpiece has been put this internal diameter into and detected among the minimum value Dmin of milscale S2, and puts to advance among the maximal value Dmax of this internal diameter detection milscale S1, explains 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 that this internal diameter detects milscale S2, the least limit deviate Dmin overproof (promptly too small) of this measured workpiece internal diameter is described; If the internal diameter of this measured workpiece has been put this internal diameter into and detected among the maximal value Dmax of milscale S1, the greatest limit deviate Dmax overproof (promptly excessive) of this measured workpiece internal diameter is described.Adopting this internal diameter to detect milscale not only can convenient, fast and accurate detection inner diameter of workpiece dimension limit; Simultaneously can also detect overproof scope; So that tell certified products, reprocessed products (if the internal diameter minimum limit of size of measured workpiece is too small; Can take special processing technology to carry out secondary processing according to circumstances, the internal diameter minimum limit of size is met the requirements) and waste product.
This a kind of digital display internal diameter detects milscale and compares with traditional digital display internal diameter test measuring device and detection method; Design ingenious, easy and simple to handle, detect accurately; Can save operator's detection time; Improving detection efficiency, is the novel product of digital display inner diameter measurement detection range, and the progress of machining being measured technology will have positive impetus.
