DETAILED DESCRIPTION

[0012] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0013] like Figure 1 and Figure 2 As shown, the utility model comprises: a frame 1 and a base 2; the frame 1 and the base 2 are fixedly connected; a steel ball bin 4 is fixedly arranged on the frame 1; a drop opening 18 is provided at the bottom of the steel ball bin 4; a cylinder bracket 6 is fixedly connected to the frame 1; a cylinder 3 is fixedly arranged on the cylinder bracket 6; a slide rail 9 is fixedly arranged on the frame 1; a slider 7 is fixedly connected to the piston rod of the cylinder 3 and is slidably connected to the slide rail 9; a push pin 8 is fixedly connected to the lower part of the slider 7; a push bin 10 is fixedly arranged on the frame 1, and its inner opening A ball track 19 and a through hole are provided; the push pin 8 is inserted into the through hole opened on the push bin 10; the gate pin 11 passes through the push bin 10; the spring 14 is sleeved on the gate pin 11; the positioning seat 12 is fixedly provided on the base 2 and is placed below the push bin 10; the upper end of the steel ball tube 13 is connected to the drop port 18, and the lower end thereof is connected to the ball track 19; the material-discharging cylinder 5 is fixedly provided on the side wall of the steel ball bin 4, and its piston rod passes through the steel ball bin 4; the material-discharging piece 17 is fixedly connected to the piston rod of the material-discharging cylinder 5.

[0014] The utility model adopts two pusher bins and six pusher pins 8 to press-fit six steel balls into a retaining frame 16 at the same time.

[0015] When doing specific operations, such as Figure 3 and Figure 4 As shown, workers put several steel balls 15 into the steel ball bin 4, and the steel balls 15 fall into the ball lanes 19 of the push bin 10 from the six drop ports 18 through the six steel ball tubes 13. Each push bin 10 has three ball lanes 19, and each push bin 10 is equipped with three push pins 8 and three gate pins 11, and the matching relationship is the same. When several steel balls 15 enter a ball lane 19 through the steel ball tubes 13, since the gate pin 11 is set below the ball lane 19, the gate pin 11 clamps the steel ball 15 to prevent it from continuing to fall along the through hole where the push pin 8 is inserted.

[0016] When assembly is required, Figure 5 and Figure 6 As shown, the worker installs the retaining frame 16 into the positioning seat 12 and operates the piston rod of the cylinder 3 to press down, forcing the slider 7 to move downward along the slide rail 9. At this time, the push pin 8 at the bottom of the slider 7 presses the steel ball 15 downward. The steel ball 15 overcomes the obstruction of the gate pin 11 and continues to move downward along the through hole and falls on the retaining frame 16. At the same time, the push pin 8 continues to press down, pressing the steel ball 15 into the retaining frame 16.

[0017] After the press-fitting is completed, the worker operates the piston rod of the cylinder 3 to retract, and the push pin 8 also moves upward. At this time, the steel ball at the bottom of the ballway 19 falls to the position as shown in FIG. Figure 4 The position is locked by the gate pin 11. The worker can repeat the above operation to continue production.

[0018] Every time 20 to 30 retainers are assembled, the worker should operate the piston rod of the material-shifting cylinder 5 to reciprocate and extend several times so that the material-shifting piece 17 can shift the steel balls in the steel ball bin 4 to prevent them from getting stuck and unable to fall into the drop opening 18.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
