The horizontal movement driving module further comprises an electrode seat, the electrode seat is provided with a through hole and an insulating surface, the through hole is arranged on the side electrode plate in a penetrating mode without contact, and the end electrode block is fixed on the insulating surface and is arranged opposite to the starting electrode block.
The arc high baffle unit 4 comprises an arc high baffle 41 and a front-back translation driving module 42, wherein the arc high baffle 41 is arranged on the test table top 1, one end of the arc high baffle is propped against the starting baffle 21 and can translate along the direction approaching to or separating from the side electrode plate 31 under the drive of the front-back translation driving module 42, specifically, the front-back translation driving module 42 comprises a plurality of long guide holes 421, a guide plate 422, two bases 423 and a sprocket chain driving assembly 424, the plurality of long guide holes 421 are arranged on the test table top 1 in the front-back direction, the two bases 423 are arranged at the bottom of the test table top 1 and are connected with the guide plate 422 through the long guide holes 421, and the two bases 423 are driven by the sprocket chain driving assembly 424 to move back and forth.
Wherein the starting electrode block 22, the side electrode plate 31 and the end electrode block 32 are all connected with the test circuit 5 but are not directly electrically conducted with each other, but are electrically conducted with the test circuit 5 through the tested rod.
The measuring process and the measuring principle of the invention are as follows:
1. When the measured rod is a long straight rod 200, as shown in fig. 4, the long straight rod 200 is placed on the workbench surface 1, the front-back translation driving module 42 drives the arc high baffle 41 to push the long straight rod 200 to lean against the side electrode plates 31, so that the long straight rod 200 at least conducts the two side electrode plates 31, the test circuit 5 controls the front-back translation driving module 42 to stop acting, the left-right translation driving module 33 drives the end electrode block 32 to move towards the direction of the start electrode block 22 until two ends of the long straight rod 200 respectively abut against and conduct the start electrode block 22 and the end electrode block 32, and the test circuit 5 controls the left-right translation driving module 33 to stop acting.
2. As shown in fig. 5, when the measured rod is the short straight rod 300, the measuring action and flow thereof are identical to those of the long straight rod 200, and will not be described herein.
3. As shown in fig. 6, when the rod to be measured is an arc rod 400, the measuring action and flow are basically identical to those of the long straight rod 200, but when the front-back translation driving module 42 drives the arc high baffle 41 to push the arc rod 400 to lean against the side electrode plates 31, two ends of the arc rod 400 can only conduct two side electrode plates 31, and the rest are identical.
As shown in fig. 3, each time a measurement is performed, the front-to-rear translation driving module 42 and the left-to-right translation driving module 33 have fixed translation starting points, that is, an arc height measurement zero point O1 and a length measurement zero point O2.
Setting the distance from the arc height measurement zero point O1 to the side electrode plate 31 as H1, and when in measurement, the distance that the front-back translation driving module 42 leans against the side electrode plate 31 until the movement is stopped as H2, wherein the measured value H of the arc height is H=H2;
similarly, let the distance from the length measurement zero point O2 to the starting electrode block 22 be L1, and when measuring, the distance that the left-right translation driving module 33 moves towards the starting electrode block 22 until stopping the motion is L2, and then the measured value L of the length is l=l1-l2;
here, since there is no so-called arc height for the long straight bar 200 and the short straight bar 300, no record can be made of the H value.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that the specific embodiments described are illustrative only and not intended to limit the scope of the invention, and that equivalent modifications and variations of the invention in light of the spirit of the invention will be covered by the claims of the present invention.
