Description

Technical Field

[0001] The utility model relates to the technical field of parallelism, in particular to a parallelism inspection tool for tensioning arms of rice transplanters. Background Art

[0002] The parallelism tester of the tension arm of the rice transplanter is a special tool used to test the parallelism of the tension arm of the rice transplanter. The parallelism of the tension arm of the rice transplanter refers to whether the tension arm of the rice transplanter is parallel to the reference plane (usually the ground). The parallelism test is to ensure that the rice transplanter can correctly clamp and place the seedlings during operation to improve the operation efficiency and quality.

[0003] However, it still has the following disadvantages in actual use:

[0004] The original detection method is to use a height gauge to detect parallelism. When using a height gauge for detection, because it is necessary to measure point by point, it may be necessary to adjust and move the position of the height gauge multiple times to obtain sufficient data. This will make the operation complicated and require more time and energy, and the efficiency is extremely low.

[0005] Therefore, a new parallelism inspection tool for tensioning arms of rice transplanters is proposed to solve the above problems. Utility Model Content

When using the height gauge for detection, because point-by-point measurement is required, the position of the height gauge may need to be adjusted and moved multiple times to obtain sufficient data, which will lead to complicated operation, require more time and energy, and have extremely low efficiency.

By using the guide rail guide fixing seat, the position of the dial indicator can be quickly moved and adjusted, so that the parallelism data of the product can be quickly and accurately obtained.

[0018] Furthermore, the dial indicator is rotatably connected to the dial indicator fixing frame via a movable shaft, and the dial indicator performs a 90-degree rotational movement in the vertical direction on the outer surface of the dial indicator fixing frame.
