[0023] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely.

[0024] Such as Figures 1 to 7As shown in the figure, a loading and unloading mechanism for a bearing grinder manipulator includes a support plate 1. An upper loading plate 2 is installed at the upper end of the support plate 1. An upper loading channel is arranged inside the upper loading plate 2. A support block 3 is arranged below the upper loading channel. The support block 3 is installed on the support plate 1. The support block 3 catches the bearing materials falling from the upper loading channel. A lower loading seat 4 is arranged below the upper loading plate 2. The lower loading seat 4 is installed on the support plate 1. A lower loading groove 5 is arranged between the lower loading seat 4 and the support plate 1. An electromagnet is installed at the inlet position of the lower loading groove 5 on the back of the support plate 1. After the electromagnet is energized, an electromagnetic adsorption area 6 is formed in this area. A processing area 7 is arranged on the sides of the upper loading plate 2 and the lower loading seat 4. A mechanical rotating arm 8 is installed on the support plate 1. A material finger 9 is installed on the mechanical rotating arm 8. The material finger 9 is connected to the central hole of the bearing material. A cylinder support is installed on the side of the support plate 1. A spherical plain bearing 10 is connected to the cylinder support. A cylinder 11 is installed on the spherical plain bearing 10. The piston end of the cylinder 11 is connected to the mechanical rotating arm 8. The cylinder 11 pushes the material finger 9 on the mechanical rotating arm 8 to rotate and convey the bearing material between the upper loading plate 2, the lower loading seat 4 and the processing area 7. In this embodiment, a stopper 12 is arranged on the side of the support block 3. The stopper 12 is installed on the support plate 1 to control the material taking position of the mechanical rotating arm 8. A swing foot 13 is installed on the support plate 1. A cam block 14 is installed at one end of the swing foot 13. The other end of the swing foot 13 is blocked by a limit post 15. A stop block 16 is connected to the mechanical rotating arm 8. When the material finger 9 is disengaged from the bearing material, the bearing material is adsorbed in the electromagnetic adsorption area 6. The stop block 16 contacts the cam block 14, and the mechanical rotating arm 8 undergoes axial displacement, causing the material finger 9 to be disengaged from the bearing material.

[0025] In this embodiment, the mechanical rotating arm 8 includes a connecting shaft 811. The connecting shaft 811 is fixed on the support plate 1. A sliding bearing 812 is connected to the connecting shaft 811. A bearing sleeve 813 is connected to the outside of the sliding bearing 812. Plug heads 814 and plug head nuts 815 are respectively connected to both ends of the bearing sleeve 813. A mechanical rotating arm housing 816 is connected to the outside of the bearing sleeve 813. A clamping bracket 817 is arranged on the mechanical rotating arm housing 816. One end of the material finger 9 is fixed inside the clamping bracket 817. A retaining ring 818 is installed at the tail of the connecting shaft 811. A pressure ring 819 is arranged inside the mechanical rotating arm housing 816. The pressure ring 819 is located between the retaining ring 818 and the plug head nut 815. The front end of the connecting shaft 811 is connected to a lock nut seat 820. The lock nut seat 820 extends into the mechanical rotating arm housing 816. A compression spring 821 is arranged between the lock nut seat 820 and the bearing sleeve 813. The compression spring 821 provides elastic force. By pressing the pressure ring 819 through the bearing sleeve 813, the mechanical rotating arm housing 816 is clamped. The stop block 16 is connected to the mechanical rotating arm housing 816. A working inclined surface 1611 and a working surface 1612 are machined on the stop block 16.

[0026] A swing foot seat 17 is installed on the support plate 1. A swing foot shaft 18 is arranged inside the swing foot seat 17. The swing foot shaft 18 is connected to the swing foot seat 17 through a swing foot bearing. Above the swing foot shaft 18, a retaining ring 19, a gasket 20 and a stop column swing foot 13 are connected. A positioning groove is machined at one end of the swing foot 13. The cam block 14 is fixed on the positioning groove. In this embodiment, the cam block 14 is made of tungsten steel. An arc surface 1411 is machined on the side surface of the cam block 14. The other end of the swing foot 13 is connected with a limit screw 21. The cap of the limit screw 21 abuts against the limit post 15. A spring seat 22 is connected to the threaded rod of the limit screw 21. A tension spring 23 is connected between the spring seat 22 and the limit post 15.

[0027] A connecting seat is arranged on the mechanical rotating arm housing 816. A fixed shaft 822 is passed through the connecting seat. The piston end of the air cylinder 11 is connected to the fixed shaft 822 through a spherical plain bearing 24.

[0028] As Figure 8 shown, the air cylinder 11 pushes the mechanical rotating arm 8 to rotate counterclockwise. The finger 9 drives the bearing material to move towards the processing area 7. At this time, the stop block 16 is away from the cam block 14. After the bearing material is ground, the piston end of the air cylinder 11 retracts, driving the mechanical rotating arm 8 to rotate clockwise. When it rotates to the electromagnetic adsorption area 6, the electromagnet is energized to adsorb the bearing material. The working inclined surface 1611 on the stop block contacts the arc surface 1411 of the cam block 14. Since the mechanical rotating arm housing 816 on the mechanical rotating arm 8 can move, during the contact process between the working inclined surface 1611 and the arc surface 1411, the mechanical rotating arm housing 816 generates an axial movement, and the mechanical rotating arm housing 816 is lifted up. The finger 9 is separated from the adsorbed bearing material. Then the mechanical rotating arm 8 continues to rotate. The working surface 1612 of the stop block 16 contacts the arc surface 1411 of the cam block 14 to keep the finger 9 in position. The electromagnet is de-energized, causing the bearing material to fall into the lower blanking chute 5. When the working surface 1612 of the stop block 16 is separated from the arc surface 1411 of the cam block 14, under the action of the compression spring 821, the mechanical rotating arm housing 816 resets, and the finger 9 moves towards the support block. The finger penetrates into the inner hole of the bearing material. Then the air cylinder 11 pushes the mechanical rotating arm 8 to rotate counterclockwise again. The stop block 16 hooks the cam block 14 to rotate until the stop block 16 is separated from the cam block 14, and the tension spring 23 resets the cam block 14.

[0029] The present utility model is not limited to the described embodiments. Those skilled in the art can still make some corrections or changes without departing from the spirit of the present utility model, that is, within the scope of the disclosure. Therefore, the scope of the right protection of the present utility model shall be subject to the scope defined by the claims.
