Problems solved by technology

But after using for a period of time, the rotating track of the turntable will accumulate dust and other dirt, so that electromagnetic radiation will be generated when the turntable rotates, which will affect the normal test, so it is necessary to disassemble the turntable and manually remove the dirt, which is time-consuming and laborious. Convenience, but also increase the cost of laboratory maintenance

Embodiment Construction

[0010] Please refer to figure 1 , the test turntable of the present invention is used to carry a test object (not shown in the figure) and can rotate 360 ​​degrees. The test turntable includes a disc-shaped bearing part 10 for carrying the test object, an annular track 20 located below the bearing part 10 , and a plurality of ring-shaped rolling elements 30 fixed on the bottom of the bearing part 10 . A cleaning member 40 is disposed on one side of each rolling member 30 .

[0011] Each rolling member 30 includes two clamping arms 32 vertically extending downward from the bottom surface of the supporting portion 10 and a roller 36 rotatably mounted on the ends of the two clamping arms 32 . The roller 36 abuts against the track 20 and can roll along the track 20 to drive the bearing part 10 to rotate.

[0012] Each cleaning element 40 includes a square-shaped mounting portion 42 and a diamond-shaped cleaning portion 46 . The top end of the installation portion 42 is fixed on...

Abstract

A test platform includes an annular rail, a supporting member rotatably mounted upon the rail, a number of wheel members mounted on a bottom of the supporting member, and a number of cleaning members mounted on the bottom of the supporting member. Each wheel member includes a wheel capable of rolling along the rail. Each cleaning member includes a cleaning portion rested on the rail. The wheels roll along the rail to rotate the supporting member and the cleaning member. The cleaning portions slide relative to and clean the rail.

Description

technical field [0001] The invention relates to a test turntable. Background technique [0002] During the electromagnetic compatibility (EMC) test, the object under test is required to rotate 360 ​​degrees to find the emission position of the maximum radiation of the object under test. At present, the general practice is to place the object under test and its test table on a large turntable, and the turntable can drive the object under test and its test table to rotate 360 ​​degrees. But after using for a period of time, the rotating track of the turntable will accumulate dust and other dirt, so that electromagnetic radiation will be generated when the turntable rotates, which will affect the normal test, so it is necessary to disassemble the turntable and manually remove the dirt, which is time-consuming and laborious. Convenience, but also increase the cost of laboratory maintenance. Contents of the invention [0003] In view of the above, it is necessary to provide a...
