Embodiment
As shown in Figure 2, Figure 3 and Figure 4, in metering pin integrated form of the present utility model, tray (well) diameter detector comprises support 6, clock gauge 4, upper gauge head 1, lower gauge head 2 and spring 5; Its medium-height trestle is U-shaped structure, 90 degree of placements of tilting, and support comprises epipleural 11, lower side panel 12 and base plate 13;
Epipleural 11 all has vertical coaxial aperture with lower side panel 12, clock gauge 4 relies on clamping plate to be fixed in the hole of epipleural 11, above the upper side edge 11 being vertically fixed on support 6, clock gauge 4 measuring junction passes epipleural 11 and connects firmly mutually with the upper gauge head 1 of below, spring is provided with between the sleeve of clock gauge 4 and upper gauge head 1, its objective is and allow gauge head 1 can contact closely with the central diameter of screw mandrel 9 with lower gauge head 2, the measuring junction of clock gauge does radial motion along with upper gauge head in the measurements, clock gauge pointer is driven to do spinning movement, thus measure the displacement obtaining the measuring junction of clock gauge.
Described lower gauge head 2 is fixed on the top of lower side panel 12 and the position corresponding with upper gauge head 1; Ball-screw 9 to be measured to be clamped between upper gauge head 1 and lower gauge head 2 bottom upper gauge head 1 and to include a hemisphere needle body 3, lower gauge head 2 top comprises two hemispheres 3, spacing between two the hemisphere needle bodies 3 wherein descending gauge head 2 is the pitch of leading screw, the size of hemisphere needle body and the metering pin of face shape and traditional measurement are consistent, use hemisphere needle body 3 to be stuck in the helicla flute of leading screw to be measured, it replaces metering pin to use.This integrated amount stylus structure, simplify and facilitate metering pin in use put requirement, this detector also can measure leading screw by vergence direction simultaneously, such as tilts the detector in Fig. 2 90 ° to can be used for too the measurement of leading screw, expands instrument application scope and occasion.
Support base plate 13 side be in U-shaped structure is inner side, and the side outside U-shaped structure is outside, and wherein inner side is fixed with adjustable plate 7.Adjustable plate 7 is the removable flat board of polylith thickness, and its effect ensures that upper and lower gauge head can fully touch on the peak of central diameter on screw mandrel, guarantees that reading is more accurate.Conveniently change the U-shaped hole (as shown in Figure 5) that adjustable plate is provided with one-sided open, adjustment 7 plate is fixed on the inner side of support base plate 13 through described U-shaped hole by screw, and so only needing to unscrew screw can change adjustable plate.Support base plate 13 arranged outside jug, easy to carry and use.
The measuring surface of upper gauge head 1 and lower gauge head 2 is provided with hemisphere needle body 3, the xsect of hemisphere needle body is semisphere, hemispheric diameter is identical with the ball diameter of leading screw, also mate with the cross-sectional dimension of traditional measurement metering pin 3, upper gauge head 1 and downside 2 adopts processing and forming or 3D to print and makes, and work in-process needs to guarantee that its face shape, size are consistent with metering pin.
The utility model in use, needs prior production standard sample bar (as shown in Figure 6), guarantees that sample bar is identical with measured leading screw parameter, and obtains its central diameter value (D0) accurately.According to three-needle measuring method, sample bar is placed on middle tray (well) diameter detector during measurement, then carries out the clearing of milscale his-and-hers watches; Then remove sample bar, change measured leading screw into, according to length and the processing request of leading screw, usually measuring the numerical value of one group of milscale every 300mm, is likely just also may be negative, with the central diameter value on sample bar for radix, in conjunction with the reading on indicator, the central diameter value of institute's survey screw mandrel can be read.
If change and detect the leading screw of different parameters, then need according to screw mandrel specification as the parameters such as steel ball, helical pitch, lead angle, public journey diameter process sample bar, upper gauge head 1, lower gauge head 2 and adjustable plate 7 again, then Installation and Debugging, and his-and-hers watches reset, and repeat above step.Because this measurement is comparing and measuring in sample bar Fundamentals of Measurement, therefore reduce the machining precision to hemisphere needle body, more feasible.
The features such as the utility model has easy to carry, and structure is simple, during central diameter when being used successfully to same specification, leading screw production and processing in enormous quantities detects.
