Then, the workpiece flows into the guide pipe 52 and is delivered to the feeding mechanism 3 in order under the mutual pushing of the workpieces, so as to realize the orderly feeding of the workpiece.

[0032] As shown in the figure, Figure 4 The punching assembly 6 includes a material collecting block 61 and a punching pipe 62, the material collecting block 61 and the punching pipe 62 are respectively connected with the machine table 1, the punching pipe 62 is arranged above the material collecting block 61, the material collecting block 61 is connected with the material guide pipe 52 and the feeding turntable 33 respectively, and the punching pipe 62 is used for connecting with a water source to flush the workpiece on the material collecting block 61 into the groove 34. In the embodiment, the punching pipe 62 is connected with the cooling system of the rotary feeding double-end-face grinding equipment, and cooling water can flow out of the punching pipe 62 in work. The punching pipe 62 can rotate on the machine table 1 to adjust the direction of the punching pipe 62, so that the cooling water flowing out of the punching pipe 62 can flush the workpiece on the material collecting block 61 into the groove 34 on the feeding turntable 33.

[0033] In specific work, the vibration disc 51 delivers the workpiece into the material guide pipe 52, under the mutual pushing and shoving of the workpieces in the material guide pipe 52, the workpieces automatically flow into the material collecting block 61; and the cooling water flowing out of the punching pipe 62 can flush the workpiece on the material collecting block 61 into the groove 34 on the feeding turntable 33, so as to realize accurate feeding of the feeding turntable 33. In the rotary feeding double-end-face grinding equipment, the punching pipe 62 is arranged, so that the flexible contact between the workpiece and the cooling water will not damage the appearance of the workpiece, thereby ensuring the yield of the processed products.

[0034] In order to facilitate the cooling water in the punching pipe 62 to successfully punch the workpiece into the material groove 34 on the feeding turntable 33, in the embodiment, the end face of the material collecting block 61 close to the punching pipe 62 is in an inclined slope structure, and the material collecting block 61 close to the feeding turntable 33 is provided with a material collecting groove 63 connected with the end of the material guide pipe 52 away from the vibration disc 51. When the vibration disc 51 works, the workpiece is orderly delivered into the material guide pipe 52 and finally falls into the material collecting groove 63 on the material collecting block 61; by arranging the material collecting groove 63, the workpiece flowing out of the material guide pipe 52 can be better collected, and the end face of the material collecting block 61 is arranged in an inclined slope shape, so that the cooling water flowing out of the punching pipe 62 can successfully punch the workpiece into the material groove 34, improving the stability of work.

[0035] As shown in Figure 3 , As shown in 5 , the machine table 1 is provided with an adjusting hand wheel 35 connected with the feeding base 31, and rotating the adjusting hand wheel 35 can drive the feeding base 31 to slide on the machine table 1; when debugging the equipment, rotating the adjusting hand wheel 35 drives the feeding base 31 to slide on the machine table 1, and the feeding base 31 drives the feeding drive assembly 32 and the feeding turntable 33 to move synchronously, so that the workpiece on the feeding turntable 33 can be successfully ground, improving the versatility of the equipment and the machining accuracy of the equipment.

[0036] The machine table 1 is provided with a material guide mechanism for aligning the workpiece in each material groove 34 to a unified position. The material guide mechanism includes a material guide plate 36 capable of covering the end face of one side of the material groove 34, and the material guide plate 36 is provided with a material guide slope 37 at a position corresponding to the material groove 34, which can be in contact with the workpiece in the material groove 34 and can push the workpiece to move axially in the material groove 34. Specifically, when the punching pipe 62 pushes the workpiece to the material groove 34, the feeding drive assembly 32 drives the feeding turntable 33 to rotate, and the feeding turntable 33 moves with the workpiece; when the workpiece moves to the corresponding position of the material guide plate 36, the material guide slope 37 on the material guide plate 36 is in contact with the workpiece, and with the continuous rotation of the feeding turntable 33, the material guide slope 37 pushes the workpiece to move axially in the material groove 34 until the position of the workpiece in each material groove 34 is uniform.

[0037] In order to improve the working stability of the material guiding mechanism, a material flushing hole 38 is arranged on the end face of the material guiding plate 36 close to one end of the feeding turntable 33, and the material flushing hole 38 is arranged at the corresponding position of the material guiding plate 36 relative to the material groove 34.

The tensioning roller 312 is slidably limited and connected with the machine table 1, and is used for tensioning the pressing belt 310. The pressing belt 310 is used for limiting the workpiece in the material groove 34. In specific work, after the material guiding plate 36 pushes the workpiece in each material groove 34 to the same position, the workpiece will be brought to the corresponding position of the pressing belt 310 with the rotation of the feeding turntable 33. The pressing belt 310 is in contact with the outer side wall of the workpiece, and limits the workpiece in the material groove 34. Then, the workpiece is delivered to the grinding mechanism 2 for grinding processing with the rotation of the feeding turntable 33. By arranging the pressing belt 310, the workpiece can be prevented from rotating in the material groove 34 during machining, so as to improve the yield of machining. The pressing belt 310 only covers part of the circumferential side wall of the feeding turntable 33. When the workpiece on the feeding turntable 33 is separated from the limitation of the pressing belt 310, the workpiece will automatically fall into the discharging mechanism 4, so as to facilitate automatic discharging.

[0054] When the workpiece moves to the corresponding position of the guide plate 36, the guide slope 37 on the guide plate 36 will be in contact with the workpiece, and as the feeding turntable 33 continues to rotate, the guide slope 37 will push the workpiece to move axially in the groove 34 until the position of the workpiece in each groove 34 is uniform; on the other hand, if the guide slope 37 is worn and cannot correct the workpiece, as the feeding turntable 33 continues to rotate to deliver the workpiece to the corresponding position of the punching hole 38, the punching hole 38 will flow out cooling water and flow to the workpiece in the groove 34, and the cooling water will push the workpiece to move axially in the groove 34, so that the position of the workpiece in each groove 34 is uniform.

[0055] After the feeding turntable 33 continues to move, the workpiece is brought to the corresponding position of the pressing belt 310, and the pressing belt 310 covers the outside of the workpiece to limit the position of the workpiece in the groove 34; then the feeding turntable 33 delivers the workpiece to the corresponding position of the grinding wheel 22, and controls the driving motor 23 to work, drives the transmission belt 25 to move, and the transmission belt 25 drives the rotating main shaft 24 to rotate, and the rotating main shaft 24 drives the grinding wheel 22 to rotate, so that the grinding wheel 22 grinds the two end faces of the workpiece to grind the workpiece to the preset size.

[0056] After grinding is completed, the workpiece processed by the feeding turntable 33 continues to move until the processed workpiece is delivered to the position where the pressing belt 310 is not limited, and at this time the workpiece will fall into the receiving hopper 41 under the action of its own gravity, and then flow from the receiving hopper 41 to the receiving box 42 to collect the processed workpiece.

[0057] The above specific embodiments are the preferred embodiments of the present application, and are not intended to limit the specific implementation range of the present application, and the scope of the present application includes but is not limited to the specific embodiments, and any equivalent changes made according to the present application are within the protection scope of the present application.
