[0004] The purpose of the present invention and the solution of its main technical problems are achieved by adopting the following technical solutions: The present invention discloses a front and back direction selection device for a headstock bowl bearing steel ball retainer, comprising a track, a direction selection groove, a slide plate, a cylinder, an inclined plate and a spiral plate, wherein a direction selection groove is arranged in the middle of the track, and the slide plate and the inclined plate are fixedly connected at both ends respectively, the track, the slide plate and the inclined plate are fixedly mounted on the side of the cylinder respectively, and a spiral plate is mounted in the cylinder.
[0005] The track is arc-shaped, with a forward channel, a reverse channel and a convex head respectively arranged on the upper and lower sides. The slide plate is fan-shaped, with a high inner side and a low outer side, and a retaining edge is arranged on the outer low surface.
[0006] The inclined plate is fan-shaped, lower inside and higher outside.
[0007] The bottom of the cylinder is in a cone shape convex upward.
[0008] The spiral plate is in a spiral shape with the inner side higher and the outer side lower.
[0009] The slide plate is fixedly connected to the outlet, and the outlet is connected to the conveying trough.
[0010] A reverse trough is installed on the side of the cylinder, and an inlet is arranged on the reverse trough.
[0011] A method for using a front and back direction selection device for a headstock bowl bearing steel ball retainer of the present invention comprises the following steps: 1) Erecting the ball retainer; The vibration pump vibrates several steel ball holders placed in the cylinder to the edge, and then moves to the top along the spiral plate. The steel ball holder slides from the top of the spiral plate to the inclined plate. The steel ball holder is tilted and the upper end is against the side of the cylinder, and the lower end is in contact with the bottom of the inclined plate. Then it slides from the inclined plate to the groove on the inclined plate and the side of the cylinder. The groove narrows from wide, and the steel ball holder moves to the narrow part and stands upright. 2) Select the front and back direction of the ball retainer; The steel ball retainer then moves to the forward channel and reverse channel on the track. The larger side of the steel ball retainer circle rolls along the forward channel on the inner surface of the track. When the smaller side of the steel ball retainer circle rolls along the inner surface of the track to the notch of the direction selection groove set on the reverse channel, the ball will fall from the notch of the direction selection groove due to the notch of the direction selection groove set on the reverse channel.
[0012] Compared with the prior art, the present invention has obvious beneficial effects; from the above technical scheme, it can be seen that: by providing a direction selection groove in the middle of the track, the two ends are respectively fixedly connected to the slide plate and the inclined plate, the track, the slide plate and the inclined plate are respectively fixedly installed on the side of the cylinder, and a spiral plate is installed in the cylinder. The steel ball retainer slides from the top of the spiral plate to the inclined plate. The steel ball retainer is tilted and the upper end is against the side of the cylinder, and the lower end is in contact with the bottom of the inclined plate. Then it slides from the inclined plate to the groove on the inclined plate and the side of the cylinder. The groove narrows from wide to narrow. The steel ball retainer moves to the narrow place and stands upright. The steel ball retainer then moves to the forward channel and the reverse channel on the track. The larger side of the steel ball retainer rolls along the forward channel on the inner surface of the track without passing through the direction selection groove (see Figure 5 , 8 9) When the small side of the steel ball retainer circle rolls along the inner surface of the track to the notch of the direction selection groove set on the reverse channel, it will fall from the notch of the direction selection groove and cannot cross the direction selection groove. The large side of the steel ball retainer circle crosses the forward channel behind the direction selection groove and rolls to the slide plate. The lower end of the steel ball retainer first leaves the forward channel on the track and slides onto the slide plate. The large steel ball retainer circle is on the slide plate, and the small steel ball retainer circle faces upward, and then flows out from the outlet into the conveying groove. There is no need to manually select the direction and turn it over, so the front and back sides of the steel ball retainer can be selected by themselves. The assembly time of the steel ball is short, the speed is fast, and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
