[0015] The adjustable support 12 is designed with four, and the four adjustable supports 12 are evenly installed on the outer circumferential surface of disc main part 11 close to the lower end position.

[0016] In use, the four adjustable supporting legs are pre-adjusted to a uniform height, and the height is locked by the upper and lower nuts. The horizontal line emitted by the laser leveler is required to be flush with the upper plane of the disc body, and when the height is adjusted, the inner nut is loosened first, and then the outer nut is rotated to extrude the vertical plate to stretch the adjusting rod outward, so that the adjusting rod and the upper pad move outward and upward along the inclined surface of the lower pad, thereby lifting one side of the disc body above, and after the adjustment is completed, the inner nut is locked on the vertical plate; when the height is adjusted, the outer nut is loosened first, and then the inner nut is rotated to extrude the vertical plate to push the adjusting rod inward, so that the adjusting rod and the upper pad move inward and downward along the inclined surface of the lower pad, thereby lowering one side of the disc body above, and after the adjustment is completed, the outer nut is locked on the vertical plate.

[0018] The outer diameter of the circular protrusion 113 is smaller than the minimum inner diameter of the center hole 32 of the tiller handle 3. This design avoids interference and ensures high precision.

[0019] A tiller fork detection method, which adopts the method of detecting the tiller fork of any one of the above-mentioned tiller fork detection platforms, and the specific steps are as follows:

[0020] 1) First, install the disc platform 1 on the horizontal ground, and fix the laser leveler 2 on one side of the disc platform 1;

[0021] 2) Turn on the laser leveler 2 to emit a horizontal plane, and use the horizontal plane to correct the upper plane of the disc body 11 of the disc platform 1;

[0022] 3) After the correction is completed, process a horizontal reference surface on the lower end surface of the poured tiller handle 3, and place the lower end surface of the tiller handle 3 on the upper plane of the disc body 11, and then perform secondary horizontal correction on the upper plane of the disc body 11, and perform fine adjustment by the adjustable supporting pad 13;

[0023] 4) Make the laser leveler 2 aim at the position of the tiller fork 31, and emit a horizontal line and a vertical line, and use a ruler to mark a fork center line at the position of the tiller fork 31, so that the vertical line coincides with the center line of the tiller, and compare whether the coincidence degree of the vertical line and the marked fork center line is within the deviation range, so as to determine the pouring deviation of the tiller fork 31; and mark a processing reference line between the vertical line and the fork center line;

[0024] 5) Put the tiller 3 into the machine tool according to the machining reference line for machining, and after the machining is completed, the steps 1-4 are repeated until the coincidence degree of the fork center line of the tiller fork 31 and the vertical line is within the error range.

[0025] The tiller needs to ensure that the center of the inner hole is on the center line of the fork on both sides. Since the casting has deviation, when the inner hole of the tiller is machined on the vertical machine tool, the position of the fork center line cannot be determined. The platform and method of the utility model can effectively solve the problem of inaccurate positioning and unable to accurately process. At the same time, the platform of the utility model is not only suitable for the detection of the tiller, but also suitable for other large castings. When the disc platform is not enough to support the casting, the castings are supported by the iron pad, and the horizontal line is virtually extended to the upper plane (reference surface) of the disc platform by the laser level, so that the upper plane of the iron pad is also the reference surface. In this way, it is not necessary to manufacture a large detection platform. The small disc body of the utility model can meet the use demand, save space, and ensure high detection accuracy.
