Problems solved by technology

Its disadvantages are: the lifting adjustment accuracy is poor, and it cannot meet the requirements of the annunciator test
Its reason is: the first, the parallelism of tested signal device 16 and magnetic conductor 15 is difficult to guarantee; Because when screw thread rotates, the levelness of signal device seat is difficult to guarantee, so the parallelism of measured signal device 16 and magnetic conductor 15 is difficult to ensure. Guaranteed, resulting in a measurement error in the distance t, which reduces the accuracy of the annunciator test
Second, due to the rotation gap of the screw thread, the lifting repeatability of the lifting screw is very poor, and it is impossible to fine-tune the height; third, the measurement accuracy of the dial indicator cannot meet the requirements

Abstract

The invention belongs to a testing technology, and relates to an improvement on an elevating device for testing a flexible gyroscope annunciator. The elevating device is characterized by consisting of a bracket (1), a one-dimensional precision displacement mechanism (2), a connecting plate (3), an annunciator seat (4), a fine adjusting hand wheel (5), a pull rod (6), an elevating screw rod (7), apull spring (8), a coarse adjusting hand wheel (9), a bearing (10), a guide key (11), a pull spring seat (12), a blocking pin (13) and a coarse adjusting hand wheel seat (14). The elevating device has very high elevation adjusting accuracy, and meets the requirement of testing on the flexible gyroscope annunciator.

Description

technical field [0001] The invention belongs to testing technology and relates to the improvement of a lifting device used for testing a flexible gyro signal device. Background technique [0002] The lifting device for FOG annunciator tests is part of the test setup for measuring FOG annunciators, see figure 1 , The test device is composed of a lifting device, a magnetic conductor 15 installed on the digital display indexing head and an output signal processing system of the annunciator. During measurement, the indexing head is rotated according to the test requirements to drive the magnetic conductor 15 to swing a certain angle relative to the signal device 16 under test, and the output of the signal device 16 is collected for processing. During the test, the horizontal distance t between the annunciator 16 under test and the magnetic conductor 15 needs to be accurately measured, and the accuracy can reach the micrometer level. The current lifting device is composed of a ...
