Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, but the present invention is not limited to the scope of the present invention.
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the slider mounting of the present invention;
the servo motor comprises a servo motor 1, a support 2, a supporting plate 3, a speed reducer mounting seat 4, a speed reducer 5, a spring 6, a guide post 7, a positioning shaft 8, a bearing seat 9, a supporting plate 10, a sliding block 11, a guide rail 12, a connecting wire 13 and an adjusting block 14.
Detailed Description
Referring to fig. 1 to 2, a reduction gear clearance automatic measuring device is shown, including servo motor 1, support 2 and backup pad 10, the upper end of support 2 is equipped with layer board 3, installs reduction gear mount pad 4 on the layer board 3, and reduction gear 5 fixes on reduction gear mount pad 4, servo motor 1 fixes in backup pad 10, and location axle 8 is installed to servo motor 1's upper end, and the top of location axle 8 is connected with reduction gear 5, the middle section of location axle 8 is equipped with bearing frame 9, and bearing frame 9 fixes in backup pad 10.
Further, a guide rail 12 is installed on the bracket 2, and a sliding block 11 matched with the guide rail 12 is arranged on the supporting plate 10.
Furthermore, guide pillars 7 are arranged on two sides of the servo motor 1, the lower ends of the guide pillars 7 penetrate through the support 2, and springs 6 are arranged on the guide pillars between the support 2 and the servo motor 1.
Further, a bearing is arranged between the bearing seat 9 and the positioning shaft 8.
Further, an adjusting block 14 is mounted on the bracket 2.
