[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0023] Please refer to Figures 1-3, in the present utility model, a steel ball detection device for assembling suspension bearing steel balls includes a guiding rail 1, the inner diameter of the guiding rail 1 is matched with the standard diameter of the suspension bearing steel balls, a discharge port 2 is provided on the guiding rail 1, an electric push rod 3 is arranged at the bottom of the guiding rail 1, a first trapezoidal slider 4 is fixedly installed on the output shaft of the electric push rod 3, a second trapezoidal slider 5 is slidably connected to the first trapezoidal slider 4, a vertical rod 6 is fixedly installed on the top of the second trapezoidal slider 5, a top block 7 is fixedly installed on the top of the vertical rod 6, the top of the top block 7 extends to the bottom of the discharge port 2, and a discharge plate 8 is fixedly installed at the bottom of the guiding rail 1, and the discharge plate 8 is located on one side of the top block 7.

[0024] In the present utility model, by placing the suspension bearing steel balls to be assembled on the guiding rail 1, the steel balls slide down along the guiding rail 1. During the sliding process of the steel balls, they will pass through the discharge port 2. The steel balls with a diameter too small to meet the assembly requirements of the suspension bearing will fall onto the top block 7. After the top block 7 moves downward, the unqualified steel balls are discharged through the discharge plate 8, while the qualified steel balls will be stuck at the discharge port 2 and cannot fall onto the top block 7. Then the electric push rod 3 works to push the first trapezoidal slider 4, jack up the second trapezoidal slider 5, thereby driving the top block 7 on the vertical rod 6 to move upward, jack up the stuck qualified steel balls, and let them continue to slide, so as to complete the diameter detection and screening work of the suspension bearing steel balls and ensure the assembly quality of the suspension bearing.

[0025] Please refer to Figure 1 , wherein: both the guiding rail 1 and the discharge plate 8 are inclined in the same direction, and the surfaces of the guiding rail 1 and the discharge plate 8 are smooth.

[0026] In the present utility model, the inclined guiding rail 1 and the discharge plate 8 facilitate the sliding of the steel balls falling thereon, thus facilitating the detection and screening work, and the smooth surface avoids the stuck state of the steel balls.

[0027] Please refer to Figure 1 and Figure 3 , wherein: the guiding rail 1 includes a steel ball feeding plate 11, a screening guide rail 12 is integrally formed on the downward inclined side of the steel ball feeding plate 11, the number of the screening guide rails 12 is more than one, and the number of the top blocks 7 is the same as the number of the screening guide rails 12.

[0028] In the present utility model, the steel ball feeding plate 11 facilitates the centralized placement of a large number of suspension bearing steel balls to be detected. Then the steel balls close to the screening guide rail 12 slide into the screening guide rail 12, which facilitates the detection and screening work. And multiple screening guide rails 12 can detect the steel balls with high efficiency and improve the detection efficiency of the suspension bearing steel ball assembly.

[0029] Please refer to Figure 1 and Figure 2 , wherein: a receiving groove 71 is provided on the top of the top block 7. When the top block 7 moves to the lowest position, the receiving groove 71 is docked with the groove on the top of the discharge plate 8.

[0030] In the present utility model, the receiving groove 71 facilitates the falling of the steel balls, and at the same time can guide the sliding direction of the steel balls after the unqualified steel balls fall, so as to facilitate the steel balls to slide out through the top groove of the discharge plate 8.

[0031] Please refer to Figures 1-3 , wherein: a replacement plate 13 is in close contact with the inner side of the screening guide rail 12, and a material dropping port corresponding to the discharge port 2 is formed on the replacement plate 13.

[0032] In the present utility model, according to the size of the suspension bearing to be assembled, the replacement plate 13 can be removed or replaced, so as to adapt to the detection and screening work of steel balls of different sizes, and the applicable range is wider.

[0033] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes an equivalent substitution or change, and should be covered by the protection scope of the present utility model.
