[0014] The utility model is described in detail below in conjunction with the accompanying drawings. As shown in Figure 1, a column fine-tuning device for a cylindricity measuring instrument includes a column adjustment plate 1, a column 2 is fixedly installed on the middle part of the upper side of the column adjustment plate 1, mounting frames 3 are respectively integrated on the front and rear sides of the upper part of the column adjustment plate 1, and fine-tuning column assemblies 4 are installed on the four corners of the column adjustment plate 1.

[0015] In this embodiment, combined with the Figure 2 As shown, the fine-tuning column assembly 4 includes a threaded column 41, an outer toothed disc 42 is integrally provided on the upper end of the threaded column 41, and gear teeth are integrally provided on the outer end of the outer toothed disc 42. A gear 44 is meshedly connected to one side of the outer toothed disc 42, and a motor 45 is installed on the lower part of the gear 44. A threaded hole is provided inside the threaded column 41, and an inner stud 43 is threadedly installed on the lower end of the threaded column 41 through the threaded hole. A limiting groove 46 is provided on one side of the lower end of the inner stud 43, and a limiting frame 47 is provided in conjunction with the limiting groove 46. One end of the limiting frame 47 is slidably provided in the limiting groove 46. The motor 45 is connected to the external control device. The motor 45 drives the outer gear plate 42 to rotate through the gear 44, thereby driving the threaded column 41 to rotate. When the threaded column 41 rotates, it drives the inner stud 43 to move. Since the inner stud 43 is limited by the limit groove 46 and the limit frame 47, the inner stud 43 moves upward or downward, thereby lifting or lowering a corner of the column adjustment plate 1, which plays a role in leveling the column 2. After leveling, the column adjustment plate 1 is fixed by the fixing device on the external cylindricity measuring instrument, thereby achieving the effect of fine-tuning and the adjustment accuracy is relatively high.

[0016] In this embodiment, specifically, every two threaded columns 41 disposed opposite to each other on the left and right sides are connected to the mounting frame 3 with a bearing.

[0017] In this embodiment, specifically, the plurality of threaded columns 41 penetrate the column adjustment plate 1 respectively.

[0018] In this embodiment, specifically, the plurality of limit frames 47 are respectively fixedly mounted on the four lower corners of the column leveling plate 1 .

[0019] How it works

[0020] In the utility model, when the user is leveling the column 2 of the cylindricity measuring instrument, the user uses the fine-tuning column assembly 4 to level the column 2, and then uses the fixing device on the external cylindricity measuring instrument to fix the column adjustment plate 1 after leveling, thereby achieving the effect of fine-tuning.

[0021] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
