DETAILED DESCRIPTION

[0019] In order to make the purpose and the advantage of the utility model more clearly, the following is further detailed with examples to the utility model.It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] As Figures 1-2As shown in the utility model embodiment, the steel ball feeding device comprises a body 1, a discharging rod 2 arranged below the body 1, a discharging channel 3 arranged in the body 1, the discharging channel 3 being communicated with the discharging rod 2, a pressing block 4 slidably connected in the body 1, a fixed jacking rod 5 arranged below the pressing block 4, one end of the fixed jacking rod 5 being arranged in the discharging channel 3, a steel ball limiting device 6 arranged on one side of the discharging channel 3, and a feeding channel 14 arranged in the body 1 and communicated with the other side of the discharging channel 3. The steel ball limiting device 6, the fixed jacking rod 5 and the discharging channel 3 form a steel ball accommodating cavity 7, and only one steel ball can be accommodated in the steel ball accommodating cavity 7. The workpiece pressure valve hole can be directly close to the discharging rod 2, and then the workpiece is pressed upward. When the body 1, the pressing block 4 and the steel ball limiting device 6 move upward together, one steel ball is discharged and falls into the workpiece pressure valve hole. After the workpiece moves downward and leaves the discharging rod 2, the next steel ball is clamped in the steel ball accommodating cavity 7, and the next workpiece pushes the discharging rod 2 upward. The device does not need compressed air or motor, and the mechanical structure is used for feeding. The device can ensure that one steel ball is loaded each time, the discharging port is automatically locked to prevent repeated loading, the steel ball free fall has no impact force, the workpiece is not damaged, and there is no safety risk. The device has small mechanism size, is easy to install, the mechanical structure is not easy to be damaged, and is easy to maintain and repair.

[0021] In order to prevent the body 1 from moving downward or upward excessively, a limiting groove 8 is arranged on the body 1, and a limiting screw 9 is connected to the body 1 through the limiting groove 8. A plurality of bolt holes 10 are arranged on the top of the pressing block 4, so as to be connected to other equipment, and the fixing of the pressing block is facilitated.

[0022] A limiting hole 11 is arranged in the body 1, the steel ball limiting device 6 comprises a limiting steel ball 12, the limiting steel ball 12 is connected to a screw 18 through a spring 13, the limiting steel ball 12 and the limiting screw 9 are arranged in the limiting hole 11, the opening of the limiting hole 11 towards the discharging channel 3 is in a circular truncated cone shape, so that the limiting steel ball 12 does not completely extend into the discharging channel 3, when the steel ball limiting device 6 moves upward, the limiting steel ball 12 moves into the limiting hole 11 under the pressure of the fixed jacking rod 5 and the steel ball, and the spring 13 deforms. When the steel ball is discharged, the spring 13 restores the deformation, and the limiting steel ball 12 returns to the previous position. In order to facilitate maintenance, the discharging rod 2 is movably connected below the discharging channel 3. In the embodiment, the discharging rod 2 is connected to the body 1 in a bolt connection mode. Figure 3 As shown in the utility model embodiment, in order to facilitate automatic feeding, a feeding port 15 is arranged on the outside of the feeding channel 14, and the feeding port 15 is connected to a steel ball hopper 17 through a hose 16.
