Specifically, the positioning plate 2 is used for being matched with a round cover mounting hole on a panel 6 of the cotton picker, and the round cover mounting hole on the panel 6 plays a role in positioning and mounting the positioning plate 2. The positioning plate 2 is provided with a second positioning hole for limiting the positioning rod 1.
One end of the positioning rod 1 is used for being inserted into a first positioning hole in a bottom plate 5 of the cotton picker, and the other end of the positioning rod 1 penetrates through a second positioning hole.
That is, the invention positions one end of the positioning rod 1 by arranging the first positioning hole on the bottom plate 5 of the cotton picker in advance, and positions the other end of the positioning rod 1 by arranging the positioning plate 2 matched with the round cover mounting hole on the panel 6 of the cotton picker and utilizing the second positioning hole on the positioning plate 2, so as to ensure the verticality of the positioning rod 1 and the middle partition plate of the cotton picker through the first positioning hole and the second positioning hole.
It should be noted that the main structure of the cotton picker in the present invention is the same as that of the conventional cotton picker in the prior art, and the panel 6, the dome mounting hole, the bottom plate 5 and the middle partition plate are all known structures of the conventional cotton picker, and are not described herein again.
It will be appreciated that the axes of the first and second locating holes are co-linear to ensure that the axes of the first and second locating holes are co-linear with the axis of the locating bar 1. Meanwhile, the axis of the first positioning hole is perpendicular to the bottom plate 5, the axis of the second positioning hole is perpendicular to the panel 6, and the panel 6, the middle partition plate and the bottom plate 5 of the cotton picker are parallel to each other, so that the perpendicularity of the positioning rod 1 and the middle partition plate can be ensured through the first positioning hole and the second positioning hole.
The detector 3 is used to detect a positional error after the cam 7 is attached, and when used, the detector 3 is provided on the positioning rod 1, and the positional error after the cam 7 is attached may be detected with the positioning rod 1 as a reference.
That is, the present invention detects a position error after the cam 7 is attached, with the positioning rod 1 as a reference. As the cam 7 is arranged on the middle partition board of the cotton picker, the invention ensures the accuracy of the detection reference by ensuring the verticality of the positioning rod 1 and the middle partition board, thereby ensuring the measurement accuracy.
Compared with the prior art that the position error of the cam 7 is detected by taking the plane of the cam 7 as a reference, the detection precision of the cam assembly detection device on the cotton picker is high, so that the measurement and adjustment times can be reduced, the assembly difficulty of the cam 7 is reduced, and meanwhile, the cam assembly precision is improved.
It should be noted that the present invention does not limit the specific structure of the detector 3 and the detection principle thereof, for example, the detector 3 may be a dial indicator.
