[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is an automatic feeding grinder workbench structure, including a conveyor belt 1 and a grinding device, the grinding device is arranged at one end of the conveyor belt 1, the outside of the conveyor belt 1 is annularly distributed with multiple shells 3, the interior of the shells 3 is provided with multiple clamps 4 for clamping the parts to be processed, multiple fixed columns 15 are installed between the shells 3 and the conveyor belt 1, one side of the conveyor belt 1 is provided with multiple fixed plates 6, the inner side surfaces of the multiple fixed plates 6 are installed with a bearing plate 7, one end of the bearing plate 7 extends to the bottom surface of the shell 3 above, and one end of the multiple fixed plates 6 is installed with a base plate 10.

[0020] In this embodiment, the grinding device includes a grinding disc 16, a protective cover, a first motor 12, a fixed frame 13 and a cylinder 17. The grinding disc 16 is arranged inside the protective cover, and the first motor 12 is installed outside the protective cover. The rotating shaft of the first motor 12 passes through the protective cover and is fixedly connected to the grinding disc 16. One end of the fixed frame 13 is installed outside the motor. The piston rod of the cylinder 17 is fixedly connected to the other end of the fixed frame 13, and the other end of the cylinder 17 is installed on the corresponding fixed plate 6.

[0021] The fixing plate is made of metal material to increase its supporting strength.

[0022] In this embodiment, multiple compression springs 5 are installed between the splint 4 and the shell 3, and a first guide portion with an arc structure is provided on both sides of the outside of the shell 3, and a second guide portion with an arc structure is provided at both ends of the supporting plate 7. When the shell rotates to the top of the conveyor belt, the first guide portion on the shell and the second guide portion on the supporting plate can enable the shell to rotate more smoothly to the upper end of the supporting plate, thereby avoiding jamming.

[0023] In this embodiment, driving rollers 2 are provided at both ends of the conveyor belt 1, and cross plates 8 are installed on the fixed plates 6 on both sides. Bearings are embedded in the cross plates 8, and the roller shafts on the driving rollers 2 are installed in the inner rings of the bearings.

[0025] During operation, the worker stands away from the grinding equipment. After pushing the clamping plate outward, the worker can put the part to be ground into the interior of the shell. After releasing the clamping plate, the rebound of the compression spring can automatically drive the clamping plate inward, thereby clamping the part;

[0026] The rotating conveyor belt can drive each shell to pass through the grinding equipment, wherein the upper surface of the part is protruding from the top surface of the shell, and the height of the grinding disc can be adjusted according to the thickness of the part. When adjusting, the cylinder is started to extend and retract the piston rod of the cylinder. The movement of the piston rod drives the fixed frame and the first motor. The first motor moves the protective cover and the grinding disc until the grinding disc can just contact the part.

[0027] The first motor can drive the grinding disc to rotate, so after the part passes through the grinding equipment, the rotating grinding disc can quickly grind the upper surface of the part. A worker can be stationed on the left side of the grinding equipment to check the grinding quality. If it is unqualified, the second motor can be started in the reverse direction to drive the reverse rotation of the conveyor belt, so that a part can be repeatedly polished to ensure the grinding quality.

[0028] Among them, after the shell rotates to the top of the conveyor belt, the bottom surface of the shell can be placed on the supporting plate to ensure the stability of the shell itself and avoid tipping over. The inner ring of the conveyor belt can be supported by the supporting plate to avoid bending of the conveyor belt and affecting the quality of grinding.
