Description
Technical Field
The utility model relates to the improvement of an optical projection type length measuring machine, in particular to a connecting device between a laser interferometer and the length measuring machine.
Background
The length measuring machine is an optical mechanical measuring instrument for measuring length, and is commonly used for directly measuring precision measuring tools, such as a micrometer calibration rod; the high-grade gauge block can be used for comparatively verifying the gauge block with the lower grade and measuring other precision parts, such as a smooth limit gauge, a smooth ring gauge, a pin gauge and the like. The reading mechanism of the traditional length measuring machine is realized by an optical projection principle, and during reading, decimeter, millimeter and micron sections need to be read respectively, and alignment needs to be carried out for many times. In actual operation, the reading error is inevitably generated due to inaccurate alignment of personnel, and the measurement accuracy is directly influenced. Therefore, it is necessary to modify the conventional length measuring machine digitally, and the laser interferometer is usually used to replace the optical projection reading mechanism of the original length measuring machine: the tripod is placed on the ground at one end of the length measuring machine, and the laser interferometer is arranged on the tripod to carry out auxiliary measurement. The method frees human eyes and reduces reading errors caused by misalignment of personnel, but the method not only needs to occupy larger space, but also can cause the shake of the laser interferometer and the relative displacement between the laser interferometer and the length measuring machine because the personnel walk near the tripod, thereby influencing the stability and the accuracy of the data measured by the laser interferometer.
Aiming at the defects in the prior art, the utility model provides the connecting device between the laser interferometer and the length measuring machine, which has the advantages of simple structure, convenience and quickness in use, space saving and capability of effectively avoiding the influence of personnel movement on the laser interferometer.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a connecting device between a laser interferometer and a length measuring machine, which has the advantages of simple structure and convenience in use, saves space and effectively avoids the influence of personnel movement on the laser interferometer.
In order to achieve the purpose, the utility model adopts the following technical scheme: a connecting device between a laser interferometer and a length measuring machine comprises a base, an adapter and a position regulator, and is characterized in that the base comprises a horizontal plate, a vertical plate and support ribs, the horizontal plate and the vertical plate are mutually perpendicular and are connected into a whole through the support ribs, the horizontal plate is provided with 2 first through holes, the vertical plate is provided with more than 3 second through holes for being connected with the length measuring machine, the adapter is of a columnar structure, the lower end of the adapter is provided with 2 threaded holes corresponding to the first through holes, the upper end of the adapter is provided with a positioning rod, the position regulator comprises a base plate, a first adjusting hand wheel and a second adjusting hand wheel, the bottom of the base plate is provided with a sleeve matched with the positioning rod, the side wall of the sleeve is provided with a jackscrew component, the base plate is provided with a laser interferometer fixing mechanism, the adapter is fixed on the horizontal plate through the threaded holes and the first through holes in cooperation with bolts, the position regulator is fixed on the adapter through the matching of the sleeve, the positioning rod and the jackscrew component.
Further, the adapter is a cylinder.
Further, the through holes are 4 and distributed at four corners of the vertical plate.
Further, the position regulator regulates the horizontal translation range of the laser interferometer in the direction perpendicular to the measuring axis of the length measuring machine to be 20 mm.
Further, the position adjuster adjusts the range of rotation of the laser interferometer in the horizontal plane to ± 5 °.
The working process of the utility model is as follows: mounting a laser interferometer on a position adjustment tool; opening the laser interferometer, installing an interference mirror, installing a reflecting mirror on an Abbe measuring head of a length measuring machine, adjusting the horizontal position of the laser interferometer in the direction vertical to the measuring axis of the length measuring machine by using a first adjusting hand wheel, adjusting the rotating angle of the laser interferometer in the horizontal plane by using a second adjusting hand wheel, and finally enabling the laser light path of the laser interferometer to be parallel to the moving direction of the Abbe measuring head; and reading the real-time position of the Abbe measuring head from the laser software of the laser interferometer by using a length measuring machine.
By adopting the utility model, the laser interferometer does not need to be additionally arranged beside the length measuring machine by a tripod, so that the space can be saved, more importantly, the laser interferometer can be directly used for a long time after being arranged once, and the laser interferometer does not need to be erected again each time, thereby not only improving the stability of data, but also avoiding the trouble that the light path of the laser interferometer needs to be readjusted because personnel walk to touch the tripod.
By adopting the utility model, the measured data can be directly read in the computer software of the laser interferometer, so that the method is more convenient and accurate; in addition, the length measuring machine does not need a light source in the original optical system any more, and the complex work caused by the fusing of the bulb is avoided.
The utility model has simple structure and convenient use.
