Description
Technical field
The utility model belongs to the Technology of Precision Measurement field, specially refers to the measurement transition apparatus that a kind of gapless accurate transmits displacement.
Background technology
Measurement is to weigh the instrument whether product reaches each grade standard, is the means of pinpointing the problems.Measurement occupies important status in mechanical industry.The accurate measurement guaranteed the interchangeability of parts and the reliability of assembling, thereby also guaranteed the quality and the performance of machine product, the life-span of having improved product.The level of measuring technique, whole value of the reliability of measurement result and surveying work are the degree of accuracy and the unitarity of measurement result.
In precision measurement, length displacement is measured most widely used general in mechanical industry.The method and apparatus of Displacement Measurement and instrument have many, such as using displacement transducer, and the torsion spring table, hundred, clock gauge, lever and gear wheel comparators etc. are measured and are shown displacement.In the displacement measurement system that has, owing to be subjected to the restriction of internal mechanical structure, these instrument can not directly contact with tested part, displacement can not directly show with these measurement devices, and intermediate demand is with measuring transition apparatus such as bascule, the parallel plate spring assembly waits and transmits displacement, so inevitable generation measuring error.
Summary of the invention
In order to better meet the requirement of accurate displacement measuring system, the utility model has designed the measurement transition apparatus that a kind of gapless accurate transmits displacement, and this measurement transition apparatus can be used as parts and uses, and is used for the displacement transmission of precision measurement.
The utility model has adopted following technical scheme:
Described gapless accurate transmits the measurement transition apparatus of displacement, it is that hollow, top and the bottom are respectively with the sleeve on internal thread and concave station rank that a centre is arranged in this measurement transition apparatus, the circular piece spring is equipped with at this place, band concave station rank, sleeve top and the bottom respectively, relies on the centering of concave station rank and the location at sleeve two ends; Boss respectively is with at the drive link two ends, and it is contained in the interstitial hole of two circular piece springs, and pad is equipped with at the drive link two ends respectively, and two ends are linked together pad, circular piece spring and drive link with gage button and measuring staff respectively; Elastic clamp seat is connected with sleeve by internal thread, and compresses the circular piece spring, and set nut is housed on elastic clamp seat, is used to clamp displacement transducer or dial gauge; Gland nut connects with sleeve by external thread, and compresses down the circular piece spring; Gauge head is housed on the measuring staff, fastening with screw; The gauge head end is inlaid with sintered carbide ball.
Owing to adopted technical scheme as mentioned above, the utlity model has following characteristics:
1. should measure transition apparatus when transmitting displacement, and meet the abbe ' s principle that length displacement is measured, there is not the errors of principles in transfer device.
2. this measurement transition apparatus has adopted circular piece spring formula guide rail, has eliminated when transmitting displacement and has produced the factor in gap, and the ergometry that produces during work is less, friction does not have substantially, the indicating value variation is little, the transmitting accuracy height, and also two circular piece springs are got the effect that fine motion is felt relieved.
3. should measure the groove structure of transition apparatus, limit maximum Displacement Measurement, and avoid the displacement of being transmitted excessive and damage transfer device, play a protective role by elastic clamp seat and gland nut.

Embodiment
As shown in Figure 1: the displacement transmitted measurement transition apparatus of gapless accurate of the present utility model, it is measured, and in transition apparatus a centre to be arranged be hollow, two ends are respectively with the sleeve (6) on internal thread and concave station rank, its external diameter clamping when measuring.A circular piece spring (4) respectively is equipped with at the position, concave station rank at two ends, and circular piece spring (4) has the semi-circular groove of twice, and the centre has the hole, external diameter is processed with a semicircular breach, rely on the centering of concave station rank and the location at sleeve (6) two ends, the semi-circular groove of twice is in order to increase elasticity and Displacement Measurement.Boss respectively is with at drive link (5) two ends, all be processed with internal thread in the middle of the two ends, the boss at two ends is contained in the interstitial hole of two circular piece springs (4) and protrudes the sheet spring, the pad at two ends (7) is contained in drive link (5) respectively and protrudes on the boss of circular piece spring (4), use gage button (3) and measuring staff (9) with pad (7) respectively, circular piece spring (4) is linked together with drive link (5).In the middle of the elastic clamp seat (2) is the hole of diameter Ф 8, and two steps and two sections screw threads are arranged on the external diameter, the end face band conical surface of top screw thread, and design has 4 open slots such as branch such as grade on the circumference, to produce elasticity.Elastic clamp seat (2) connects with sleeve (6) with screw thread, and compress circular piece spring (4), the set nut (1) of band inner conical surface is housed on the elastic clamp seat (2), tighten set nut (1), contact by interior male cone (strobilus masculinus), make elastic clamp seat (2) with the generation elastic deformation, thereby clamp displacement transducer or dial gauge.Gland nut (8) connects with sleeve (6) with screw thread, and compresses down the circular piece spring.Gauge head (10) is housed on the measuring staff (9), and tightens up with screw (12).Gauge head (10) end is inlaid with sintered carbide ball (11), and contact workpiece during in order to measurement is with anti-wear.
The concrete using method of measurement transition apparatus of the present utility model is as follows:
1), displacement transducer or dial gauge are packed in the elastic clamp seat (2), the measuring head of displacement transducer or dial gauge is contacted gently with gage button (3), with set nut (1) with displacement transducer or dial gauge locking;
